A total of 179 patients with obscure gastrointestinal bleeding (OGIB) referred for DBE from June 2004 to November 2008 were analysed looking for the incidence of non-small-bowel lesions (NSBLs; all and newly diagnosed) encountered during DBE.RESULTS: There were 228 (150 antegrade and 78 retrograde) DBE procedures performed in 179 patients. The mean number of DBE procedures was 1.27 per patient. The mean age (SD) of the patients was 62 ± 16 years old. There were 94 females (52.5%). The positive yield for a bleeding lesion was 65.9%. Of the 179 patients, 44 (24.6%) had NSBLs (19 of them had dual pathology with small-bowel lesions and NSBLs); 27 (15.1%) had lesions not detected by previous endoscopies. The most common type of missed lesions were vascular lesions.CONCLUSION: A significant proportion of patients (24.6%) had lesions within reach of conventional endoscopy. Careful repeat examination with gastroscopy and colonoscopy might be required.展开更多

The patients with gastrointestinal obstructions,fistulas, strictures, or cardiac pacemakers, as well as pregnant women, and individuals who could not accept the capsule-retention or capsule-removal surgery were excluded. Patients with heart, lung and other vital organ failure diseases were also excluded. Everyone involved in this study had undergone CE and DBE. The results were divided into:(1) the definite diagnosis(the diagnosis was confirmed at least by one of the biopsy,surgery, pathology or the drug treatment effects with follow-up for at least 3 mo);(2) the possible diagnosis(a possible diagnosis was suggested by CE or DBE,but not confirmed by the biopsy, surgery or follow-up drug treatment effects); and(3) the unclear diagnosis(no exact causes were provided by CE and DBE for the disease). The detection rate and the diagnostic yield of the two methods were compared. The differencein the etiologies between CE and DBE was estimated,and the different possible etiologies caused by the age groups were also investigated.RESULTS: CE exhibited a better trend than DBE for diagnosing scattered small ulcers(P = 0.242, Fisher's test), and small vascular malformations(χ 2 = 1.810,P = 0.179, Pearson χ 2 test), but with no significant differences, possible due to few cases. However,DBE was better than CE for larger tumors(P =0.018, Fisher's test) and for diverticular lesions with bleeding ulcers(P = 0.005, Fisher's test). All three hemangioma cases diagnosed by DBE in this study(including sponge hemangioma, venous hemangioma,and hemangioma with hamartoma lesions) were all confirmed by biopsy. Two parasite cases were found by CE, but were negative by DBE. This study revealed no obvious differences in the detection rates(DR) of CE(60.0%, 53/88) and DBE(59.1%, 52/88). However,the etiological diagnostic yield(DY) difference was apparent. The CE diagnostic yield was 42.0%(37/88),and the DBE diagnostic yield was 51.1%(45/88).Furthermore, there were differences among the age groups(χ 2 = 22.146, P = 0.008, Kruskal Wallis Test). Small intestinal cancer(5/6 cases), vascular malformations(22/29 cases), and active bleeding(3/4cases) appeared more commonly in the patients over50 years old, but diverticula with bleeding ulcers were usually found in the 15-25-year group(4/7cases). The over-25-year group accounted for the stromal tumors(10/12 cases).CONCLUSION: CE and DBE each have their own advantages and disadvantages. The appropriate choice depends on the patient's age, tolerance, and clinical manifestations. Sometimes CE followed by DBE is necessary.展开更多

METHODS: Four hundred and forty consecutive DBE examinations were performed in 400 patients (250 males and 150 females, mean age 46.9 ± 16.3 years, range 14-86 years) between January 2007 and April 2012. Of these, 252 patients underwent the antegrade approach, and 188 patients underwent the retrograde approach. All the patients enrolled in our study were suspected of having small bowel diseases with a negative etiological diagnosis following other routine examinations, such as upper and lower gastrointestinal endoscopy and radiography tests. Data on tumors, such as clinical information, endoscopic findings and opera-tion results, were retrospectively collected. RESULTS: Small bowel tumors were diagnosed in 78 patients, of whom 67 were diagnosed using DBE, resulting in a diagnostic yield of 16.8% (67/400); the other 11 patients had negative DBE findings and were diagnosed through surgery or capsule endoscopy. Adenocarcinoma (29.5%, 23/78), gastrointestinal stromal tumor (24.4%, 19/78) and lymphoma (15.4%, 12/78) were the most common tumors. Among the 78 tumors, 60.3% (47/78) were located in the jejunum, and the overall number of malignant tumors was 74.4% (58/78). DBE examinations were frequently performed in patients with obscure gastrointestinal bleeding (47.4%) and abdominal pain (24.4%). The positive detection rate for DBE in the 78 patients with small bowel tumors was 85.9% (67/78), which was higher than that of a computed tomography scan (72.9%, 51/70). Based on the operation results, the accuracy rates of DBE for locating small bowel neoplasms, such as adenocarcinoma, gastrointestinal stromal tumor and lymphoma, were 94.4%, 100% and 100%, respectively. The positive biopsy rates for adenocarcinoma and lymphoma were 71.4% and 60%, respectively. CONCLUSION: DBE is a useful diagnostic tool with high clinical practice value and should be considered the gold standard for the investigation of small bowel tumors.展开更多

METHODS: The data about 75 OGIB patients who underwent DBE in January 2007-June 2009 in our hospital were retrospectively analyzed. RESULTS: DBE was successfully performed in all 75 patients without complication. Of the 75 patients, 44 (58.7%) had positive DBE findings, 22 had negative DBE findings but had potential bleeding at surgery and capsule endoscopy, etc . These 66 patients were finally diagnosed as OGIB which was most commonly caused by small bowel tumor (28.0%), angiodysplasia (18.7%) and Crohn’s disease (10.7%). Lesions occurred more frequently in proximal small bowel than in distal small bowel (49.3% vs 33.3%, P = 0.047). CONCLUSION: DBE is a safe, effective and accurate procedure for the diagnosis of OGIB.展开更多

METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, 3apan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis. RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3 out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm. CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel.展开更多

METHODS: A retrospective analysis in a tertiary referral center. This study reviewed all cases from June 2006 to April 2011 with a target lesion in the small-bowel identified by either capsule endoscopy or computed tomography scan posted for DBE examinations. Main outcome measurements were: (1) Technical success of aDBE def ined by f inding or excluding a target lesion after achieving suff icient length of small bowel intubation; and (2) Technical success for rDBE was def ined by either f inding the target lesion or achieving stable overtube placement in the ileum. RESULTS: Two hundred and eighty two procedures fulf illed the inclusion criteria and were analyzed. These procedures were analyzed by blocks of 30 cases. Therewas no distinct learning curve for aDBE. Technical success rates for rDBE continued to rise over time, although on logistic regression analysis testing for trend, there was no signif icance (P = 0.09). The odds of success increased by a factor of 1.73 (95% CI: 0.93-3.22) for rDBE. For these data, it was estimated that at least 30-35 cases of rDBE under supervision were needed to achieve a good technical success of more than 75%. CONCLUSION: There was no learning curve for aDBE. Technical success continued to increase over time for rDBE, although a learning curve could not be proven statistically. Approximately 30-35 cases of rDBE will be required for stable overtube intubation in ileum.展开更多

An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital. She was suspected of having bleeding from the jejunum, and was referred to our department for diagnosis and treatment. An oral DBE revealed a 20 mm × 10 mm, regularly surfaced, white to yellowish, elongated, pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz. Since no other source of bleeding was identified by endoscopy in the deep jejunum, anendoscopic polypectomy (EP) was performed for this lesion. A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions. Although clip-ping hemostasis was performed during EP, re-bleeding occurred. Finally, a complete hemostasis was achieved by performing an additional argon plasma coagulation.展开更多

Here, we report a 48-year-old man with SBA and a 21-year history of CD who was diagnosed by a combination of positron emission tomography/computed tomography (PET/CT) and double-balloon enteroscopy (DBE). Since the age of 27 years, the patient had been treated for ileal CD and was referred to our hospital with persistent melena. Multiple hepatic tumors were found by CT. PET/CT detected an accumulation spot in the small bowel. DBE revealed an ulcerative tumor in the ileum about 100 cm from the ileocecal valve. An endoscopic forceps biopsy specimen showed poorly differentiated adenocarcinoma. There were some longitudinal ulcer scars near the tumor, and the chronic inflammation inthe small bowel appeared to be associated with the cancer development. Previous reports suggest the risk of SBA in patients with CD is higher than in the overall population. Since early diagnosis is extremely difficult in these cases, novel techniques, such as PET/CT and DBE, may be expected to help in making a preoperative diagnosis of the development of SBA in CD.展开更多

Here, we report ...An inverted Meckel’s diverticulum is a rare gastrointestinal congenital anomaly that is difficult to diagnose prior to surgery and presents with anemia, abdominal pain, or intussusception. Here, we report the case of 57-year-old men with an inverted Meckel’s diverticulum, who was preoperatively diagnosed using double-balloon enteroscopy. He had repeatedly experienced epigastric pain for 2 mo. Ultrasonography and computed tomography showed intestinal wall thickening in the pelvis. Double-balloon enteroscopy via the anal route was performed for further examination, which demonstrated an approximately 8-cm, sausage-shaped, submucosal tumor located approximately 80 cm proximal to the ileocecal valve. A small depressed erosion was observed at the tip of this lesion. Forceps biopsy revealed heterotopic gastric mucosa. Thus, the patient was diagnosed with an inverted Meckel’s diverticulum, and single-incision laparoscopic surgery was performed. This case suggests that an inverted Meckel’s diverticulum should be considered as a differential diagnosis for a submucosal tumor in the ileum. Balloon-assisted enteroscopy with forceps biopsy facilitate a precise diagnosis of this condition.展开更多

METHODS: Between September 2006 and April 2011, 47 procedures of DB-ERCP were performed in 28 patients with a Roux-en-Y total gastrectomy (n = 11), Billroth Ⅱ gastrectomy (n = 15), or Roux-en-Y anastomosis with hepaticojejunostomy (n = 2). DB-ERCP was performed using a short-type DBE combined with several technical innovations such as using an endoscope attachment, marking by submucosal tattooing,selectively applying contrast medium, and CO2 insufflations. RESULTS: The papilla of Vater or hepaticojejunostomy site was reached in its entirety with a 96% success rate (45/47 procedures). There were no significant differences in the success rate of reaching the blind end with a DBE among Roux-en-Y total gastrectomy (96%), Billroth Ⅱ reconstruction (94%), or pancreatoduodenectomy (100%), respectively (P = 0.91). The total successful rate of cannulation and contrast enhancement of the target bile duct in patients whom the blind end was reached with a DBE was 40/45 procedures (89%). Again, there were no significant differences in the success rate of cannulation and contrast enhancement of the target bile duct with a DBE among Roux-en-Y total gastrectomy (88 %), Billroth Ⅱ reconstruction (89%), or pancreatoduodenectomy (100%), respectively (P = 0.67). Treatment was achieved in all 40 procedures (100%) in patients whom the contrast enhancement of the bile duct was successful. Common endoscopic treatments were endoscopic biliary drainage (24 procedures) and extraction of stones (14 procedures). Biliary drainage was done by placement of plastic stents. Stones extraction was done by lithotomy with the mechanical lithotripter followed by extraction with a basket or by the balloon pull-through method. Endoscopic sphincterotomy was performed in 14 procedures with a needle precutting knife using a guidewire. The mean total duration of the procedure was 93.6 ± 6.8 min and the mean time required to reach the papilla was 30.5 ± 3.7 min. The mean time required to reach the papilla tended to be shorter in Billroth Ⅱ reconstruction (20.9 ± 5.8 min) than that in Roux-en-Y total gastrectomy (37.1 ± 4.9 min) but there was no significant difference (P = 0.09). A major complication occurred in one patient (3.5%); perforation of the long limb in a patient with Billroth Ⅱ anastomosis.CONCLUSION: Short-type DBE combined with several technical innovations enabled us to perform ERCP in most patients with altered gastrointestinal anatomy.展开更多

METHODS: We retrospectively reviewed 56 patients who underwent double-balloon enteroscopy to localize intestinal bleeding prior to surgical intervention, and compared enteroscopic findings with those of intraoperation to determine the accuracy of enteroscopy in identifying and localizing the sites of small intestinal bleeding. RESULTS: Double-balloon enteroscopy was performed in all 56 patients in a 30-mo period. A possible site of blood loss was identified in 54 (96%) patients. Enteroscopy provided accurate localization of the bleeding in 53 (95%) of 56 patients, but failed to disclose the cause of bleeding in 4 (7%). There was one case with negative intraoperative finding (2%). Resection of the affected bowel was carried out except one patient who experienced rebleeding after operation. Gastrointestinal stromal tumor (GIST) was most frequently diagnosed (55%). CONCLUSION: Double-balloon enteroscopy is a safe, reliable modality for determining bleeding lesion of small intestine. This technique can be used to direct selective surgical intervention.展开更多

METHODS: The medical files of patients who underwent DBE at Gazi University School of Medicine, Ankara, Turkey between 2009 and 2011 were examined retrospectively. Adult and pediatric patients were compared according to DBE indications, procedure duration, final diagnosis, and complications. DBE procedures were performed in an operating room under general anesthesia by two endoscopists. An oral or anal approach was preferred according to estimated lesion sites. Overnight fasting of at least 6 h prior to the start of the procedure was adequate for preprocedural preparation of oral DBE procedures. Bowel cleansing was performed by oral administration of sennosides A and B solution, 2 mL/kg, and anal saline laxative en-ema. The patients were followed up for 2 h after the procedure in terms of possible complications. RESULTS: DBE was performed in 35 patients (5 pediatric and 30 adult). DBE procedures were performed for abdominal pain, chronic diarrhea, bleeding, chronic vomiting, anemia, and postoperative evaluation of anastomosis. Final diagnosis was diffuse gastric angiodysplasia (n = 1); diffuse jejunal angiodysplasia (n = 1); ulceration in the bulbus (n = 1); celiac disease (n = 1); low differentiated metastatic carcinoma (n = 1); PeutzJeghers syndrome (n = 1); adenomatous polyp (n = 1) and stricture formation in anastomosis line (n = 1). During postprocedural follow-up, abdominal pain and elevated amylase levels were noted in three patients and one patient developed abdominal perforation. CONCLUSION: With the help of technological improvements, we may use enteroscopy as a safe modality more frequently in younger and smaller children.展开更多

AIM: To assess the diagnostic success and outcome among patients with obscure gastrointestinal bleeding who underwent total enteroscopy with double-balloon endoscopy.
文摘AIM:To report the incidence of non-small-bowel bleeding pathologies encountered during double-balloon enteroscopy (DBE) procedures and to analyse their significance.METHODS: A retrospective study of a prospective DBE database conducted in a tertiary-referral center was conducted. A total of 179 patients with obscure gastrointestinal bleeding (OGIB) referred for DBE from June 2004 to November 2008 were analysed looking for the incidence of non-small-bowel lesions (NSBLs; all and newly diagnosed) encountered during DBE.RESULTS: There were 228 (150 antegrade and 78 retrograde) DBE procedures performed in 179 patients. The mean number of DBE procedures was 1.27 per patient. The mean age (SD) of the patients was 62 ± 16 years old. There were 94 females (52.5%). The positive yield for a bleeding lesion was 65.9%. Of the 179 patients, 44 (24.6%) had NSBLs (19 of them had dual pathology with small-bowel lesions and NSBLs); 27 (15.1%) had lesions not detected by previous endoscopies. The most common type of missed lesions were vascular lesions.CONCLUSION: A significant proportion of patients (24.6%) had lesions within reach of conventional endoscopy. Careful repeat examination with gastroscopy and colonoscopy might be required.
文摘AIM: To compare the roles of capsule endoscopy(CE)and double-balloon enteroscopy(DBE) in the diagnosis of obscure small bowel diseases.METHODS: From June 2009 to December 2014, 88 patients were included in this study; the patients had undergone gastroscopy, colonoscopy, radiological small intestinal barium meal, abdominal computed tomography or magnetic resonance imaging scan and mesenteric angiography, but their diagnoses were still unclear. The patients with gastrointestinal obstructions,fistulas, strictures, or cardiac pacemakers, as well as pregnant women, and individuals who could not accept the capsule-retention or capsule-removal surgery were excluded. Patients with heart, lung and other vital organ failure diseases were also excluded. Everyone involved in this study had undergone CE and DBE. The results were divided into:(1) the definite diagnosis(the diagnosis was confirmed at least by one of the biopsy,surgery, pathology or the drug treatment effects with follow-up for at least 3 mo);(2) the possible diagnosis(a possible diagnosis was suggested by CE or DBE,but not confirmed by the biopsy, surgery or follow-up drug treatment effects); and(3) the unclear diagnosis(no exact causes were provided by CE and DBE for the disease). The detection rate and the diagnostic yield of the two methods were compared. The differencein the etiologies between CE and DBE was estimated,and the different possible etiologies caused by the age groups were also investigated.RESULTS: CE exhibited a better trend than DBE for diagnosing scattered small ulcers(P = 0.242, Fisher's test), and small vascular malformations(χ 2 = 1.810,P = 0.179, Pearson χ 2 test), but with no significant differences, possible due to few cases. However,DBE was better than CE for larger tumors(P =0.018, Fisher's test) and for diverticular lesions with bleeding ulcers(P = 0.005, Fisher's test). All three hemangioma cases diagnosed by DBE in this study(including sponge hemangioma, venous hemangioma,and hemangioma with hamartoma lesions) were all confirmed by biopsy. Two parasite cases were found by CE, but were negative by DBE. This study revealed no obvious differences in the detection rates(DR) of CE(60.0%, 53/88) and DBE(59.1%, 52/88). However,the etiological diagnostic yield(DY) difference was apparent. The CE diagnostic yield was 42.0%(37/88),and the DBE diagnostic yield was 51.1%(45/88).Furthermore, there were differences among the age groups(χ 2 = 22.146, P = 0.008, Kruskal Wallis Test). Small intestinal cancer(5/6 cases), vascular malformations(22/29 cases), and active bleeding(3/4cases) appeared more commonly in the patients over50 years old, but diverticula with bleeding ulcers were usually found in the 15-25-year group(4/7cases). The over-25-year group accounted for the stromal tumors(10/12 cases).CONCLUSION: CE and DBE each have their own advantages and disadvantages. The appropriate choice depends on the patient's age, tolerance, and clinical manifestations. Sometimes CE followed by DBE is necessary.
文摘AIM: To analyze the clinical characteristics of small bowel tumors detected by double-balloon enteroscopy (DBE) and to evaluate the diagnostic value of DBE in tumors. METHODS: Four hundred and forty consecutive DBE examinations were performed in 400 patients (250 males and 150 females, mean age 46.9 ± 16.3 years, range 14-86 years) between January 2007 and April 2012. Of these, 252 patients underwent the antegrade approach, and 188 patients underwent the retrograde approach. All the patients enrolled in our study were suspected of having small bowel diseases with a negative etiological diagnosis following other routine examinations, such as upper and lower gastrointestinal endoscopy and radiography tests. Data on tumors, such as clinical information, endoscopic findings and opera-tion results, were retrospectively collected. RESULTS: Small bowel tumors were diagnosed in 78 patients, of whom 67 were diagnosed using DBE, resulting in a diagnostic yield of 16.8% (67/400); the other 11 patients had negative DBE findings and were diagnosed through surgery or capsule endoscopy. Adenocarcinoma (29.5%, 23/78), gastrointestinal stromal tumor (24.4%, 19/78) and lymphoma (15.4%, 12/78) were the most common tumors. Among the 78 tumors, 60.3% (47/78) were located in the jejunum, and the overall number of malignant tumors was 74.4% (58/78). DBE examinations were frequently performed in patients with obscure gastrointestinal bleeding (47.4%) and abdominal pain (24.4%). The positive detection rate for DBE in the 78 patients with small bowel tumors was 85.9% (67/78), which was higher than that of a computed tomography scan (72.9%, 51/70). Based on the operation results, the accuracy rates of DBE for locating small bowel neoplasms, such as adenocarcinoma, gastrointestinal stromal tumor and lymphoma, were 94.4%, 100% and 100%, respectively. The positive biopsy rates for adenocarcinoma and lymphoma were 71.4% and 60%, respectively. CONCLUSION: DBE is a useful diagnostic tool with high clinical practice value and should be considered the gold standard for the investigation of small bowel tumors.
文摘AIM: To evaluate the diagnostic value of double-balloon enteroscopy (DBE) for obscure gastrointestinal bleeding (OGIB). METHODS: The data about 75 OGIB patients who underwent DBE in January 2007-June 2009 in our hospital were retrospectively analyzed. RESULTS: DBE was successfully performed in all 75 patients without complication. Of the 75 patients, 44 (58.7%) had positive DBE findings, 22 had negative DBE findings but had potential bleeding at surgery and capsule endoscopy, etc . These 66 patients were finally diagnosed as OGIB which was most commonly caused by small bowel tumor (28.0%), angiodysplasia (18.7%) and Crohn’s disease (10.7%). Lesions occurred more frequently in proximal small bowel than in distal small bowel (49.3% vs 33.3%, P = 0.047). CONCLUSION: DBE is a safe, effective and accurate procedure for the diagnosis of OGIB.
文摘AIM:To assess the value of double-balloon enteroscopy(DBE) for the diagnosis of gastrointestinal mesenchymal tumors(GIMTs) in the small bowel and clarify their clinical and endoscopic characteristics.METHODS:A retrospective review in a total of 783 patients who underwent a DBE procedure from January 2003 to December 2011 was conducted.Data from patients with pathologically confirmed GIMTs were analyzed at a single tertiary center with nine years' experience.The primary outcomes assessed included characteristics of patients with GIMTs,indications for DBE,overall diagnostic yield of GIMTs,endoscopic morphology,positive biopsy,comparison of diagnosis with capsule endoscopy,and subsequent interventional management.RESULTS:GIMTs were identified and analyzed in 77 patients.The mean age was 47.74 ± 14.14 years(range:20-77 years),with 63.6% being males.The majority of individuals presented with gastrointestinal bleeding,accounting for 81.8%,followed by abdominal pain,accounting for 10.4%.Small bowel pathologies were found in 71 patients,the detection rate was 92.2%.The diagnostic yield of DBE for GIMTs was 88.3%.DBE was superior to capsule endoscopy in the diagnosis of GIMTs(P = 0.006;McNemar's χ2 test).Gastrointestinal stromal tumor was the most frequent and leiomyoma was the second frequent GIMT.Single and focal lesions were typical of GIMTs,and masses with smooth or unsmooth surface were the most common in the small bowel.GIMTs were removed from all the patients surgically except one patient treated with endoscopic resection.CONCLUSION:DBE is a safe and valuable procedure for patients with suspected GIMTs,and it provides an accurate position for subsequent surgical intervention.
文摘AIM: To investigate the correlations between serum amylase levels, intestinal permeability (IP), and pancreatic injury and to explore the mechanisms responsible for hyperamylasemia in double-balloon enteroscopy (DBE).
文摘AIM:To evaluate the clinical outcome of enteroscopy, using the double-balloon method, focusing on the involvement of neoplasms in strictures of the small intestine. METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, 3apan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis. RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3 out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm. CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel.
文摘AIM: To determine the learning curves for antegrade double-balloon enteroscopy (aDBE) and retrograde DBE (rDBE) by analyzing the technical success rates. METHODS: A retrospective analysis in a tertiary referral center. This study reviewed all cases from June 2006 to April 2011 with a target lesion in the small-bowel identified by either capsule endoscopy or computed tomography scan posted for DBE examinations. Main outcome measurements were: (1) Technical success of aDBE def ined by f inding or excluding a target lesion after achieving suff icient length of small bowel intubation; and (2) Technical success for rDBE was def ined by either f inding the target lesion or achieving stable overtube placement in the ileum. RESULTS: Two hundred and eighty two procedures fulf illed the inclusion criteria and were analyzed. These procedures were analyzed by blocks of 30 cases. Therewas no distinct learning curve for aDBE. Technical success rates for rDBE continued to rise over time, although on logistic regression analysis testing for trend, there was no signif icance (P = 0.09). The odds of success increased by a factor of 1.73 (95% CI: 0.93-3.22) for rDBE. For these data, it was estimated that at least 30-35 cases of rDBE under supervision were needed to achieve a good technical success of more than 75%. CONCLUSION: There was no learning curve for aDBE. Technical success continued to increase over time for rDBE, although a learning curve could not be proven statistically. Approximately 30-35 cases of rDBE will be required for stable overtube intubation in ileum.
文摘We report a rare case of a small-bowel lymphangioma causing massive gastrointestinal (GI) bleeding that we successfully diagnosed and treated using double-balloon enteroscopy (DBE). An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital. She was suspected of having bleeding from the jejunum, and was referred to our department for diagnosis and treatment. An oral DBE revealed a 20 mm × 10 mm, regularly surfaced, white to yellowish, elongated, pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz. Since no other source of bleeding was identified by endoscopy in the deep jejunum, anendoscopic polypectomy (EP) was performed for this lesion. A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions. Although clip-ping hemostasis was performed during EP, re-bleeding occurred. Finally, a complete hemostasis was achieved by performing an additional argon plasma coagulation.

文摘AIM:To evaluate the efficacy of endoscopic diagnosis and therapy for jejunal diverticular bleeding.METHODS:From January 2004 to September 2009,154 patients underwent double-balloon enteroscopy (DBE) for obscure gastrointestinal bleeding.Ten consecutive patients with jejunal diverticula (5 males and 5 females) at the age of 68.7 ± 2.1 years (range 1995 years) at Chang Gung Memorial Hospital,Academic Tertiary Referral Center,were enrolled in this study.RESULTS:Of the 10 patients,5 had melena,2 had hematochezia,2 had both melena and hematochezia,1 had anemia and dizziness.DBE revealed ulcers with stigmata of recent hemorrhage in 6 patients treated by injection of epinephrine diluted at 1:10 000,Dieulafoylike lesions in 4 patients treated by deploying hemoclips on the vessels,colonic diverticula in 2 patients,and duodenal diverticula in 3 patients,respectively.Of the 2patients who underwent surgical intervention,1 had a large diverticulum and was referred by the surgeon for DBE,1 received endoscopic therapy but failed due to massive bleeding.One patient had a second DBE for recurrent hemorrhage 7 mo later,which was successfully treated with a repeat endoscopy.The mean follow-up time of patients was 14.7 ± 7.8 mo.CONCLUSION:DBE is a safe and effective treatment modality for jejunal diverticular bleeding.
文摘Endoscopic intervention is less invasive than percutaneous or surgical approaches and should be considered the primary drainage procedure in most cases with obstructive jaundice.Recently,therapeutic endoscopic retrograde cholangiopancreatography(ERCP) using double-balloon enteroscopy(DBE) has been shown to be feasible and effective,even in patients with surgically altered anatomies.On the other hand,endoscopic partial stent-in-stent(PSIS) placement of selfexpandable metallic stents(SEMSs) for malignant hilar biliary obstruction in conventional ERCP has also been shown to be feasible,safe and effective.We performed PSIS placement of SEMSs for malignant hilar biliary obstruction due to liver metastasis using a short DBE in a patient with Roux-en-Y anastomosis and achieved technical and clinical success.This procedure can result in quick relief from obstructive jaundice in a single session and with short-term hospitalization,even in patients with surgically altered anatomies.
文摘Small bowel adenocarcinoma (SBA) in patients with Crohn’s disease (CD) is quite rare, difficult to diagnose without surgery, and has a poor prognosis. Here, we report a 48-year-old man with SBA and a 21-year history of CD who was diagnosed by a combination of positron emission tomography/computed tomography (PET/CT) and double-balloon enteroscopy (DBE). Since the age of 27 years, the patient had been treated for ileal CD and was referred to our hospital with persistent melena. Multiple hepatic tumors were found by CT. PET/CT detected an accumulation spot in the small bowel. DBE revealed an ulcerative tumor in the ileum about 100 cm from the ileocecal valve. An endoscopic forceps biopsy specimen showed poorly differentiated adenocarcinoma. There were some longitudinal ulcer scars near the tumor, and the chronic inflammation inthe small bowel appeared to be associated with the cancer development. Previous reports suggest the risk of SBA in patients with CD is higher than in the overall population. Since early diagnosis is extremely difficult in these cases, novel techniques, such as PET/CT and DBE, may be expected to help in making a preoperative diagnosis of the development of SBA in CD.
文摘An inverted Meckel’s diverticulum is a rare gastrointestinal congenital anomaly that is difficult to diagnose prior to surgery and presents with anemia, abdominal pain, or intussusception. Here, we report the case of 57-year-old men with an inverted Meckel’s diverticulum, who was preoperatively diagnosed using double-balloon enteroscopy. He had repeatedly experienced epigastric pain for 2 mo. Ultrasonography and computed tomography showed intestinal wall thickening in the pelvis. Double-balloon enteroscopy via the anal route was performed for further examination, which demonstrated an approximately 8-cm, sausage-shaped, submucosal tumor located approximately 80 cm proximal to the ileocecal valve. A small depressed erosion was observed at the tip of this lesion. Forceps biopsy revealed heterotopic gastric mucosa. Thus, the patient was diagnosed with an inverted Meckel’s diverticulum, and single-incision laparoscopic surgery was performed. This case suggests that an inverted Meckel’s diverticulum should be considered as a differential diagnosis for a submucosal tumor in the ileum. Balloon-assisted enteroscopy with forceps biopsy facilitate a precise diagnosis of this condition.
文摘AIM: To investigate the clinical outcome of double balloon enteroscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (DB-ERCP) in patients with altered gastrointestinal anatomy. METHODS: Between September 2006 and April 2011, 47 procedures of DB-ERCP were performed in 28 patients with a Roux-en-Y total gastrectomy (n = 11), Billroth Ⅱ gastrectomy (n = 15), or Roux-en-Y anastomosis with hepaticojejunostomy (n = 2). DB-ERCP was performed using a short-type DBE combined with several technical innovations such as using an endoscope attachment, marking by submucosal tattooing,selectively applying contrast medium, and CO2 insufflations. RESULTS: The papilla of Vater or hepaticojejunostomy site was reached in its entirety with a 96% success rate (45/47 procedures). There were no significant differences in the success rate of reaching the blind end with a DBE among Roux-en-Y total gastrectomy (96%), Billroth Ⅱ reconstruction (94%), or pancreatoduodenectomy (100%), respectively (P = 0.91). The total successful rate of cannulation and contrast enhancement of the target bile duct in patients whom the blind end was reached with a DBE was 40/45 procedures (89%). Again, there were no significant differences in the success rate of cannulation and contrast enhancement of the target bile duct with a DBE among Roux-en-Y total gastrectomy (88 %), Billroth Ⅱ reconstruction (89%), or pancreatoduodenectomy (100%), respectively (P = 0.67). Treatment was achieved in all 40 procedures (100%) in patients whom the contrast enhancement of the bile duct was successful. Common endoscopic treatments were endoscopic biliary drainage (24 procedures) and extraction of stones (14 procedures). Biliary drainage was done by placement of plastic stents. Stones extraction was done by lithotomy with the mechanical lithotripter followed by extraction with a basket or by the balloon pull-through method. Endoscopic sphincterotomy was performed in 14 procedures with a needle precutting knife using a guidewire. The mean total duration of the procedure was 93.6 ± 6.8 min and the mean time required to reach the papilla was 30.5 ± 3.7 min. The mean time required to reach the papilla tended to be shorter in Billroth Ⅱ reconstruction (20.9 ± 5.8 min) than that in Roux-en-Y total gastrectomy (37.1 ± 4.9 min) but there was no significant difference (P = 0.09). A major complication occurred in one patient (3.5%); perforation of the long limb in a patient with Billroth Ⅱ anastomosis.CONCLUSION: Short-type DBE combined with several technical innovations enabled us to perform ERCP in most patients with altered gastrointestinal anatomy.
文摘AIM: To evaluate preoperative double-balloon enteroscopy for determining bleeding lesions of small intestine, thus directing selective surgical intervention. METHODS: We retrospectively reviewed 56 patients who underwent double-balloon enteroscopy to localize intestinal bleeding prior to surgical intervention, and compared enteroscopic findings with those of intraoperation to determine the accuracy of enteroscopy in identifying and localizing the sites of small intestinal bleeding. RESULTS: Double-balloon enteroscopy was performed in all 56 patients in a 30-mo period. A possible site of blood loss was identified in 54 (96%) patients. Enteroscopy provided accurate localization of the bleeding in 53 (95%) of 56 patients, but failed to disclose the cause of bleeding in 4 (7%). There was one case with negative intraoperative finding (2%). Resection of the affected bowel was carried out except one patient who experienced rebleeding after operation. Gastrointestinal stromal tumor (GIST) was most frequently diagnosed (55%). CONCLUSION: Double-balloon enteroscopy is a safe, reliable modality for determining bleeding lesion of small intestine. This technique can be used to direct selective surgical intervention.
文摘A 73-year old man presented with abdominal pain. A tumor with central ulceration was observed in the ileum using double-balloon enteroscopy. Histological findings of the biopsy specimens were consistent with malignant lymphoma. Double-balloon enteroscopy confirmed the diagnosis of a malignant lymphoma tumor which was surgically resected. The patient is still in complete remission now.
文摘BACKGROUND Double-balloon,single-balloon,and spiral enteroscopy(DBE,SBE,and SE)have revolutionized the management of intestinal diseases.However,evidence about efficacies of these methods is lacking.We aimed to conduct a meta-analysis comparing the clinical outcomes among DBE,SBE,and SE.METHODS We searched randomized controlled trials and prospective studies in MEDLINE,PubMed,EMBASE,Cochrane Library,and Chinese CQVIP database.Studies referencing the comparison of at least two of these three methods were included.Primary outcome was diagnostic yield.Other outcomes were therapeutic yield,total enteroscopy,examination time,time to maximum insertion,and depth of maximal insertion(DMI).RESULTS Eleven studies including 727 patients were identified:DBE vs SE(n=6),DBE vs SBE(n=4),and SBE vs SE(n=1).The diagnostic and therapeutic yields did not differ significantly when comparing DBE with SE[odds ratio(OR)=1.19,95%confidence interval(CI):0.68-2.08;OR=1.17,95%CI:0.61-2.23]and DBE with SBE(OR=0.85,95%CI:0.55-1.33;OR=1.71,95%CI:0.64-4.60).Total enteroscopy,examination time,time to maximum insertion,and DMI were similar between SBE and DBE.DBE was superior to SE with regard to DMI[mean difference(MD)=36.76,95%CI:5.09-68.43],with longer time to maximum insertion(MD=15.14,95%CI:12-18.27)and examination time(MD=12.98,95%CI:9.57-16.38).CONCLUSION DBE and SBE have similar clinical outcomes.Compared with DBE,SE seems to have similar diagnostic and therapeutic yields,but shorter procedural time in cost of less depth of insertion.SE needs further evaluation vs SBE.DBE is recommended for complete enteroscopy.
文摘AIM: To compare results of double balloon enteroscopy (DBE) procedures in pediatric and adult patients. METHODS: The medical files of patients who underwent DBE at Gazi University School of Medicine, Ankara, Turkey between 2009 and 2011 were examined retrospectively. Adult and pediatric patients were compared according to DBE indications, procedure duration, final diagnosis, and complications. DBE procedures were performed in an operating room under general anesthesia by two endoscopists. An oral or anal approach was preferred according to estimated lesion sites. Overnight fasting of at least 6 h prior to the start of the procedure was adequate for preprocedural preparation of oral DBE procedures. Bowel cleansing was performed by oral administration of sennosides A and B solution, 2 mL/kg, and anal saline laxative en-ema. The patients were followed up for 2 h after the procedure in terms of possible complications. RESULTS: DBE was performed in 35 patients (5 pediatric and 30 adult). DBE procedures were performed for abdominal pain, chronic diarrhea, bleeding, chronic vomiting, anemia, and postoperative evaluation of anastomosis. Final diagnosis was diffuse gastric angiodysplasia (n = 1); diffuse jejunal angiodysplasia (n = 1); ulceration in the bulbus (n = 1); celiac disease (n = 1); low differentiated metastatic carcinoma (n = 1); PeutzJeghers syndrome (n = 1); adenomatous polyp (n = 1) and stricture formation in anastomosis line (n = 1). During postprocedural follow-up, abdominal pain and elevated amylase levels were noted in three patients and one patient developed abdominal perforation. CONCLUSION: With the help of technological improvements, we may use enteroscopy as a safe modality more frequently in younger and smaller children.
文摘AIM:To review safety,efficacy,and proper nursing care of double-balloon enteroscopy (DBE) in pediatric patients with small intestinal disease.METHODS:Our study included 37 patients with abdominal pain,diarrhea,passage of blood in the stools,and other symptoms,who underwent DBE from December 2006 to July 2010.DBE was retrograde in 36 procedures,antegrade in six,and from both ends in five.The diagnostic significance and salient points in nursing care are discussed in this article.RESULTS:At least one lesion was discovered in 28 out of 37 patients,which yielded a positive diagnosis in 75.7% of cases.Good bowel preparation and skilled nursing care not only shortened the procedure time,but could also alleviate patient discomfort and enhance the quality of examination.No serious procedure-related complications were observed in any cases.CONCLUSION:DBE is a new modality of endoscopic procedure that improves the standard of diagnosis and treatment of small bowel diseases in children.Good nursing care is essential to the successful execution of the procedure.
文摘AIM: To assess the diagnostic success and outcome among patients with obscure gastrointestinal bleeding who underwent total enteroscopy with double-balloon endoscopy.
