Even though the incidence of peptic ulcer disease and gastritis is decreasing, the incidence rates in neoplasm, Dieulafoy’s lesions, angiodysplasia, and esophagitis are trending up, which necessities physicians to be aware of those pathologies and their specifics. Here, we represent a case of a 62-year-old male on dual antiplatelet therapy who was transferred to our hospital due to severe melena with suspicion of upper gastrointestinal bleeding. Due to hemodynamic instability, the patient was intubated and started on vasopressors. However, several repeated EGDs and CTs of the abdomen with GI bleeding protocol did not reveal the location of active bleeding to stop it. At the same time, clinically, the patient was hemodynamically unstable with continued melena. On the last EGD, a small area of concern resembling gastric varix was clipped for identification purposes, and the patient underwent a selective angiogram with further diagnosis of Dieulafoy’s lesion, which was successfully embolized. Our case demonstrates that Dieulafoy’s lesions can present as severe life-threatening hemorrhage, hard to diagnose with traditional methods such as EGD or CTs, in which case it is recommended to proceed with an angiogram sooner rather than later for further diagnosis and treatment if needed.展开更多

It was subsequently diagnosed as Dieulafoy’s lesion localized in the lesser curvature of the stomach. Endoscopic diagnosis and treatment were done by angiographic embolization. Dieulafoy’s lesion is considered rare even for adult cases, much more for pediatric patients and usually underdiagnosed. Hence, patients presenting with gastrointestinal bleeding should be managed in a multidisciplinary approach. Spreading awareness about this lesion by including it in the considerations, may help improve early detection and treatment.展开更多

METHODS:All patients who received emergency upper gastrointestinal(GI)endoscopy due to gastric DL from February 2000 to August 2008 at GI endoscopy center of Renmin Hospital of Wuhan University were included in this study.The clinical presentation,medical history,location and characteristics of DL methods and effectiveness of therapy of patients with DL were retrospectively analysed by chart reviews.Long-term follow-up data were collected at outpatient clinics or telephone interviews. RESULTS:Fifteen patients were diagnosized with DL,which account for 1.04%of the source of bleed- ing in acute non-variceal upper GI bleeding.Common comorbidities were found in one patient with hypertension and diabetic mellitus.Hemoclip or combined therapy with hemoclip produced primary hemostasis in 92.8%(13/14) of patients. CONCLUSION:DL is uncommon but life-threatening in China.Hemoclip proved to be safe and effective in controlling bleeding from DL.展开更多

Early endoscopy during a bleeding episode is essential for an accurate diagnosis and sometimes multiple endoscopies are needed to establish the diagnosis. In this report, we describe a case of duodenal DL detected and treated by endoscopy. We report the case of a 65-year-old patient admitted for massive upper gastrointestinal bleeding due to a Dieulafoy lesion of the duodenum. Endoscopic diagnosis and treatment were possible and hemostasis was achieved by injecting adrenaline and placing 3 clips. Various effective endoscopic techniques are available to control bleeding, the combination of injection therapy and mechanical therapy reduces the risk of recurrence.展开更多

METHODS: One hundred and seven patients with gastrointestinal bleeding due to Dieulafoy's lesion were treated with three endoscopic hemostasis methods: aethoxysklerol injection (46 cases), endoscopic hemoclip hemostasis (31 cases), and a combination of hemoclip hemostasis with aethoxysklerol injection (30 cases). RESULTS: The rates of successful hemostasis using the three methods were 71.7% (33/46), 77.4% (24/31) and 96.7% (29/30), respectively, with significant differences between the methods (P 〈 0.05). Among those who had unsuccessful treatment with aethoxysklerol injection, 13 were treated with hemoclip hemostasis and 4 underwent surgical operation; 9 cases were successful in the injection therapy. Among the cases with unsuccessful treatment with hemoclip hemostasis,7 were treated with injection of aethoxysklerol and 3 cases underwent surgical operation; 4 cases were successful in the treatment with hemoclip hemostasis. Only 1 case had unsuccessful treatment with a combined therapy of hemoclip hemostasis and aeth- oxysklerol injection, and surgery was then performed. No serious complications of perforation occurred in the patients whose bleeding was treated with the endoscopic hemostasis, and no releeding was found during a 1-year follow-up. CONCLUSION: The combined therapy of hemoclip hemostasis with aethoxysklerol injection is the most effective method for gastrointestinal bleeding due to Dieulafoy's lesion.展开更多

CASE SUMMARY A 44-year-old female with medical history of chronic renal failure who was on renal replacement therapy presented with lower gastrointestinal hemorrhage. Physical examination revealed signs of hypovolemic shock and massive rectal bleeding. Complete blood count revealed abrupt decrease in hematocrit. After hemodynamic stabilization, an urgent colonoscopy was performed. A rectal DL was diagnosed, and it was successfully treated with two hemoclips. There were no signs of recurrent bleeding at thirty days of follow-up. CONCLUSION Rectal DLs represent an unusual cause of lower gastrointestinal bleeding. Massive hemorrhage can increase the morbidity and mortality of these patients. Endoscopic management continues to be the reference standard in the diagnosis and therapy of these lesions. Thermal, mechanical (hemoclip or band ligation), or combination therapy (adrenaline injection combined with thermal or mechanical therapy) should be considered the first choice for treatment.展开更多

A Dieulafoy’s lesion is an aberrant vessel that does not reduce in caliber when it extends from the submucosa to the mucosa. Damage to this artery can cause severe and intermittent arterial bleeding from small vascular stumps that are difficult to visualize. Furthermore, these catastrophic bleeding episodes frequently result in hemodynamic instability and the need for transfusion of multiple blood products. Recently, uremic syndrome has been identified as a risk factor for gastric mucosal lesions. We present two clinical cases of acute digestive bleeding due to Dielafoy lesion with chronic kidney disease as the main cause, where two different therapies were performed endoscopically. We concluded with the results of our patients that the best therapy was the application of the hemostatic hemoclip on the injury vs the injection with adrenaline on the wound site. Uremia is identified as a risk factor for upper gastrointestinal bleeding in patients with pre-existing Dieulafoy’s lesion, as well as a higher incidence of new bleeding.展开更多

Frequently, more than one enteroscopy is needed to identify the bleeding vessel. In our practice, video capsule endoscopy (VCE) identified and guided therapy in four cases of DLs-like; three of them were localized on the small bowel. We report, for the first time, a diagnosis of colonic DL-like performed by colon capsule endoscopy. Two patients presented with severe cardiovascular disorders, being hemodynamically unstable during VCE examination. Based on the VCE findings, only one invasive therapeutic procedure per patient was necessary to achieve hemostasis. VCE and enteroscopy may be regarded as complementary procedures in patients with gut DLs-like.展开更多

METHODS: Retrospective study of patients with gas- trointestinal bleeding secondary to Dieulafoy's lesion (DL) from 2005 to 2011. We analyzed the demographic characteristics of the patients, risk factors for gastro- intestinal bleeding, endoscopic findings, characteristics of the endoscopic treatment, and the recurrence of bleeding. We included cases in which endoscopy de- scribed a lesion compatible with Dieulafoy. We exclud- ed patients who had potentially bleeding lesions such as angiodysplasia in other areas or had undergone other gastrointestinal endoscopic procedures. RESULTS: Twenty-nine patients with DL were identi- fied. Most of them were men with an average age of 71.5 years. Fifty-five percent of the patients received antiaggregatory or anticoagulant therapy. The most common location for DL was the stomach (51.7%). The main type of bleeding was oozing in 65.5% of cases. In 27.6% of cases, there was arterial (spurting) bleeding, and 6.9% of the patients presented with an adherent clot. A single endoscopic treatment was ap- plied to nine patients (31%), eight of them with adren- aline and one with argon, while 69% of the patients received combined treatment. Six patients (20.7%) presented with recurrent bleeding at a median of 4 d after endoscopy (interquartile range = 97.75). Within these six patients, the new endoscopic treatment ob- tained a therapeutic success of 100%. The presence of arterial bleeding at endoscopy was associated with a higher recurrence rate for bleeding (50% vs 33.3% for other type of bleeding) rP = 0.024, odds ratio (OR) = 8.5, 95% CI = 1.13-63.87]. The use of combined en- doscopic treatment prevented the recurrence of bleed- ing (10% vs 44.4% of single treatment) (P = 0.034, OR = 0.14, 95% CI = 0.19-0.99). CONCLUSION: Endoscopic treatment of DL is safe and effective. Adrenaline monotherapy and arterial (spurting) bleeding are associated with a high rate of bleeding recurrence.展开更多

There are no recommendations regarding the prime endoscopic treatment technique for this condition. A 61-year-old woman presented with melena without signs of hemodynamic instability. During an urgent upper endoscopy, blood oozing from the normal mucosa of the duodenum was seen and this was classified as a Dieulafoy's lesion. A mini-loop was opened at the rim of a transparent ligation chamber, at the end of the endoscope, and after aspiration of the lesion, closed and detached. Complete hemostasis was achieved without early or postponed complications. In every day clinical practice, mini-loop ligation is rarely used because of possible complications, such as site ulceration, organ perforation, re-bleeding and possible inexperience of the operator. To the best of our knowledge this is the first case of successful treatment of bleeding duodenal Dieulafoy's lesion by mini-loop ligation.展开更多

Mortality rates are similar to those of other causes for gastrointestinal bleeding. Diagnosis by upper endoscopy is the modal-ity of choice during acute bleeding. In the absence of active bleeding, the lesion resembles a raised nipple or visible vessel. There are no guidelines regarding effective selective therapy for DL, when diagnosed, en-doscopist experience is the major determinant of the treatment strategy. Following our strategy, an expert endoscopist with a skilled assistant should have a high rate of successful DL diagnosis when an obscured gas-trointestinal lesion is suspected. Cyanoacryltes com-pounds have been used successfully in management of Gastric varices and DLs. To our knowledge, there have been no previous reports regarding use of isoamyl-2-cyanoacrylate (AMCRYLATE ; Concord Drugs Ltd.,Hyderabad, India) as an effective therapy for gastric DL without serious complications. In our case study, Isoamyl-2-cyanoacrylate (AMCRYLATE) was effective and safe for treating DL. Surgical wedge resection of the lesion should be considered as a therapeutic option if endoscopic therapy fails.展开更多

Unlike normal vessels of the gastrointestinal tract which become progressively smaller in caliber peripherally, Dieulafoy's lesions maintain a large caliber despite their peripheral, submucosal, location within gastrointestinal wall. Dieulafoy's lesions typically present with severe, active, gastrointestinal bleeding, without prior symptoms; often cause hemodynamic instability and often require transfusion of multiple units of packed erythrocytes. About 75% of lesions are located in the stomach, with a marked proclivity of lesions within 6 cm of the gastroesophageal junction along the gastric lesser curve, but lesions can also occur in the duodenum and esophagus. Lesions in the jejunoileum or colorectum have been increasingly reported. Endoscopy is the first diagnostic test, but has only a 70% diagnostic yield because the lesions are frequently small and inconspicuous. Lesions typically appear at endoscopy as pigmented protuberances from exposed vessel stumps, with minimal surrounding erosion and no ulceration(visible vessel sans ulcer). Endoscopic therapy, including clips, sclerotherapy, argon plasma coagulation, thermocoagulation, or electrocoagulation, is the recommended initial therapy, with primary hemostasis achieved in nearly 90% of cases. Dual endoscopic therapy of epinephrine injection followed by ablative or mechanical therapy appears to be effective. Although banding is reportedly highly successful, it entails a small risk of gastrointestinal perforation from banding deep mural tissue. Therapeutic alternatives after failed endoscopic therapy include repeat endoscopic therapy, angiography, or surgical wedge resection. The mortality has declined from about 30% during the 1970's to 9%-13% currently with the advent of aggressive endoscopic therapy.展开更多

Demographic data, mode of presentation, riskfactors for gastrointestinal bleeding, blood transfusion requirements, endoscopic findings, details of endoscopic therapy, recurrence of bleeding, and mortality rates were collected and analyzed retrospectively.RESULTS: Hemostasis was attempted by dextrose 50% plus epinephrine in 10 patients, hemoclipping in 8 patients,heater probe in 2 patients and ethanolamine oleate in 2 patients. Comorbid conditions were present in 17 patients (74%). Overall permanent hemostasis was achieved in 18 patients (78%). Initial hemostasis was successful with no recurrent bleeding in patients treated with hemoclipping, heater probe or ethanolamine injection. In the group of patients who received dextrose 50% plus epinephrine injection treatment, four (40%) had recurrent bleeding and one (10%) had unsuccessful initial hemostasis.Of the four patients who had rebleeding, three had unsuccessful hemostasis with similar treatment. Surgical treatment was required in five patients (22%) owing to uncontrolled bleeding, recurrent bleeding with unsuccessful retreatment and inability to approach the lesion. One patient (4.3%) died of sepsis after operation during hospitalization. There were no side-effects related to endoscopic therapy. None of the patients in whom permanent hemostasis was achieved presented with rebleeding from Dieulafoy's lesion over a mean long-term follow-up of 29.8 mo.CONCLUSION: Bleeding from Dieulafoy's lesions can be managed successfully by endoscopic methods, which should be regarded as the first choice. Endoscopic hemoclipping therapy is recommended for bleeding Dieulafoy's lesions.展开更多

They are largely under recognised and difficult to treat. Up to 95% occur in the stomach, and only case reports document their occurrence in the small bowel(SB). Little is known about their pathophysiology, although there have been associations made previously with chronic liver disease, thought to be due to the erosive effects of alcohol on the mucosa overlying the abnormally dilated vessels. We present a case series of 4 patients with a long duration of obscure gastrointestinal bleeding, who were diagnosed with small intestinal DLs and incidentally diagnosed with chronic liver disease. The histories describe the challenges in both diagnosis and treatment of small intestinal DLs. Our case series suggest a previously unreported link between chronic liver disease and SB DLs which may be due to anatomical vasculature changes or a shift in angiogenic factors as a consequence of portal hypertension or liver cirrhosis.展开更多

METHODS:Endoscopic data from esophagogastroduo denoscopies (EGDs),done at Wyckoff Heights Medical Center,Brooklyn,NY between 2000 and 2006 were reviewed to identify patients with Dieulafoy's lesions. Demographic data,medical history,examination findings,lab data,endoscopic findings and details of therapy for patients treated for Dieulafoy's lesions were reviewed retrospectively. RESULTS:Dieulafoy's lesions were documented to be the cause of bleeding in approximately 1% of patients presenting with upper gastrointestinal bleeding,while they were detected in only 2 patients when the indications for EGDs were different from active GI bleeding. When we analyzed EGDs performed in patients above age 65 years presenting with gastrointestinal bleeding,prevalence of Dieulafoy's lesions approached 10 percent. The most common location of the lesion was the body of stomach (7),followed by the cardia (4) and the esophagus (2). One patient had this lesion in the fundus and one patient in the duodenal apex. All patients were initially treated endoscopically with epinephrine injection,in eight cases heater probe was applied following epinephrine and endoscopic clips were applied in two cases. All but one of the patients did well in near and intermediate term follow-up (average follow-up period of 18 mo). One patient died of multi-organ failure during the same hospital stay. Average length hospital stay was 7 d.CONCLUSION:Community hospital gastroenterologists and endoscopists should be aware that Dieulafoy's lesions are an uncommon cause of upper GI bleeding among elderly patients. Early accurate diagnosis through emergent endoscopy and endoscopic therapy,especially in patients with multiple co-morbid conditions,can be very effective and life saving.展开更多

文摘Upper gastrointestinal bleeding remains a significant cause of hospital admissions. Even though the incidence of peptic ulcer disease and gastritis is decreasing, the incidence rates in neoplasm, Dieulafoy’s lesions, angiodysplasia, and esophagitis are trending up, which necessities physicians to be aware of those pathologies and their specifics. Here, we represent a case of a 62-year-old male on dual antiplatelet therapy who was transferred to our hospital due to severe melena with suspicion of upper gastrointestinal bleeding. Due to hemodynamic instability, the patient was intubated and started on vasopressors. However, several repeated EGDs and CTs of the abdomen with GI bleeding protocol did not reveal the location of active bleeding to stop it. At the same time, clinically, the patient was hemodynamically unstable with continued melena. On the last EGD, a small area of concern resembling gastric varix was clipped for identification purposes, and the patient underwent a selective angiogram with further diagnosis of Dieulafoy’s lesion, which was successfully embolized. Our case demonstrates that Dieulafoy’s lesions can present as severe life-threatening hemorrhage, hard to diagnose with traditional methods such as EGD or CTs, in which case it is recommended to proceed with an angiogram sooner rather than later for further diagnosis and treatment if needed.
文摘This is a case of a 5-month-old infant who experienced repeated episodes of hematemesis and no known underlying health conditions. It was subsequently diagnosed as Dieulafoy’s lesion localized in the lesser curvature of the stomach. Endoscopic diagnosis and treatment were done by angiographic embolization. Dieulafoy’s lesion is considered rare even for adult cases, much more for pediatric patients and usually underdiagnosed. Hence, patients presenting with gastrointestinal bleeding should be managed in a multidisciplinary approach. Spreading awareness about this lesion by including it in the considerations, may help improve early detection and treatment.

文摘Dieulafoy lesion (DL) is a rare source of gastrointestinal tract bleeding that can affect any site of the gastrointestinal tract, particularly the stomach and less commonly the duodenum. Early endoscopy during a bleeding episode is essential for an accurate diagnosis and sometimes multiple endoscopies are needed to establish the diagnosis. In this report, we describe a case of duodenal DL detected and treated by endoscopy. We report the case of a 65-year-old patient admitted for massive upper gastrointestinal bleeding due to a Dieulafoy lesion of the duodenum. Endoscopic diagnosis and treatment were possible and hemostasis was achieved by injecting adrenaline and placing 3 clips. Various effective endoscopic techniques are available to control bleeding, the combination of injection therapy and mechanical therapy reduces the risk of recurrence.

文摘AIM: To investigate the endoscopic hemostasis for gastrointestinal bleeding due to Dieulafoy's lesion. METHODS: One hundred and seven patients with gastrointestinal bleeding due to Dieulafoy's lesion were treated with three endoscopic hemostasis methods: aethoxysklerol injection (46 cases), endoscopic hemoclip hemostasis (31 cases), and a combination of hemoclip hemostasis with aethoxysklerol injection (30 cases). RESULTS: The rates of successful hemostasis using the three methods were 71.7% (33/46), 77.4% (24/31) and 96.7% (29/30), respectively, with significant differences between the methods (P 〈 0.05). Among those who had unsuccessful treatment with aethoxysklerol injection, 13 were treated with hemoclip hemostasis and 4 underwent surgical operation; 9 cases were successful in the injection therapy. Among the cases with unsuccessful treatment with hemoclip hemostasis,7 were treated with injection of aethoxysklerol and 3 cases underwent surgical operation; 4 cases were successful in the treatment with hemoclip hemostasis. Only 1 case had unsuccessful treatment with a combined therapy of hemoclip hemostasis and aeth- oxysklerol injection, and surgery was then performed. No serious complications of perforation occurred in the patients whose bleeding was treated with the endoscopic hemostasis, and no releeding was found during a 1-year follow-up. CONCLUSION: The combined therapy of hemoclip hemostasis with aethoxysklerol injection is the most effective method for gastrointestinal bleeding due to Dieulafoy's lesion.
文摘BACKGROUND Rectal Dieulafoy's lesions (DLs) are very rare;however, they can be life threatening when presented with massive hemorrhage. CASE SUMMARY A 44-year-old female with medical history of chronic renal failure who was on renal replacement therapy presented with lower gastrointestinal hemorrhage. Physical examination revealed signs of hypovolemic shock and massive rectal bleeding. Complete blood count revealed abrupt decrease in hematocrit. After hemodynamic stabilization, an urgent colonoscopy was performed. A rectal DL was diagnosed, and it was successfully treated with two hemoclips. There were no signs of recurrent bleeding at thirty days of follow-up. CONCLUSION Rectal DLs represent an unusual cause of lower gastrointestinal bleeding. Massive hemorrhage can increase the morbidity and mortality of these patients. Endoscopic management continues to be the reference standard in the diagnosis and therapy of these lesions. Thermal, mechanical (hemoclip or band ligation), or combination therapy (adrenaline injection combined with thermal or mechanical therapy) should be considered the first choice for treatment.
文摘Dieulafoy’s lesions are rare vascular malformations of the gastrointestinal tract. A Dieulafoy’s lesion is an aberrant vessel that does not reduce in caliber when it extends from the submucosa to the mucosa. Damage to this artery can cause severe and intermittent arterial bleeding from small vascular stumps that are difficult to visualize. Furthermore, these catastrophic bleeding episodes frequently result in hemodynamic instability and the need for transfusion of multiple blood products. Recently, uremic syndrome has been identified as a risk factor for gastric mucosal lesions. We present two clinical cases of acute digestive bleeding due to Dielafoy lesion with chronic kidney disease as the main cause, where two different therapies were performed endoscopically. We concluded with the results of our patients that the best therapy was the application of the hemostatic hemoclip on the injury vs the injection with adrenaline on the wound site. Uremia is identified as a risk factor for upper gastrointestinal bleeding in patients with pre-existing Dieulafoy’s lesion, as well as a higher incidence of new bleeding.
文摘AIM:To systematically review the data on distinctive aspects of peptic ulcer disease(PUD),Dieulafoy’s lesion(DL),and Mallory-Weiss syndrome(MWS)in patients with advanced alcoholic liver disease(a ALD),including alcoholic hepatitis or alcoholic cirrhosis.METHODS:Computerized literature search performed via Pub Med using the following medical subject heading terms and keywords:"alcoholic liver disease","alcoholic hepatitis","alcoholic cirrhosis","cirrhosis","liver disease","upper gastrointestinal bleeding","nonvariceal upper gastrointestinal bleeding","PUD",‘‘DL’’,‘‘Mallory-Weiss tear",and"MWS’’.RESULTS:While the majority of acute gastrointestinal(GI)bleeding with a ALD is related to portal hypertension,about 30%-40%of acute GI bleeding in patients with a ALD is unrelated to portal hypertension.Such bleeding constitutes an important complication of a ALD because of its frequency,severity,and associated mortality.Patients with cirrhosis have a markedly increased risk of PUD,which further increases with the progression of cirrhosis.Patients with cirrhosis or a ALD and peptic ulcer bleeding(PUB)have worse clinical outcomes than other patients with PUB,including uncontrolled bleeding,rebleeding,and mortality.Alcohol consumption,nonsteroidal anti-inflammatory drug use,and portal hypertension may have a pathogenic role in the development of PUD in patients with a ALD.Limited data suggest that Helicobacter pylori does not play a significant role in the pathogenesis of PUD in most cirrhotic patients.The frequency of bleeding from DL appears to be increased in patients with a ALD.DL may be associated with an especially high mortality in these patients.MWS is strongly associated with heavy alcohol consumption from binge drinking or chronic alcoholism,and is associated with a ALD.Patients with a ALD have more severe MWS bleeding and are more likely to rebleed when compared to non-cirrhotics.Preendoscopic management of acute GI bleeding in patients with a ALD unrelated to portal hypertension is similar to the management of a ALD patients with GI bleeding from portal hypertension,because clinical distinction before endoscopy is difficult.Most patients require intensive care unit admission and attention to avoid over-transfusion,to correct electrolyte abnormalities and coagulopathies,and to administer antibiotic prophylaxis.Alcoholics should receive thiamine and be closely monitored for symptoms of alcohol withdrawal.Prompt endoscopy,after initial resuscitation,is essential to diagnose and appropriately treat these patients.Generally,the same endoscopic hemostatic techniques are used in patients bleeding from PUD,DL,or MWS in patients with a ALD as in the general population.CONCLUSION:Nonvariceal upper GI bleeding in patients with a ALD has clinically important differences from that in the general population without a ALD,including:more frequent and more severe bleeding from PUD,DL,or MWS.
文摘Dieulafoy's-like lesions (DLs-like) represent a cause of obscure gastrointestinal bleeding, enteroscopy being the main diagnostic and therapeutic procedure. Frequently, more than one enteroscopy is needed to identify the bleeding vessel. In our practice, video capsule endoscopy (VCE) identified and guided therapy in four cases of DLs-like; three of them were localized on the small bowel. We report, for the first time, a diagnosis of colonic DL-like performed by colon capsule endoscopy. Two patients presented with severe cardiovascular disorders, being hemodynamically unstable during VCE examination. Based on the VCE findings, only one invasive therapeutic procedure per patient was necessary to achieve hemostasis. VCE and enteroscopy may be regarded as complementary procedures in patients with gut DLs-like.
文摘AIM: To analyze the effectiveness of the endoscopic therapy and to identify prognostic factors for recurrent bleeding. METHODS: Retrospective study of patients with gas- trointestinal bleeding secondary to Dieulafoy's lesion (DL) from 2005 to 2011. We analyzed the demographic characteristics of the patients, risk factors for gastro- intestinal bleeding, endoscopic findings, characteristics of the endoscopic treatment, and the recurrence of bleeding. We included cases in which endoscopy de- scribed a lesion compatible with Dieulafoy. We exclud- ed patients who had potentially bleeding lesions such as angiodysplasia in other areas or had undergone other gastrointestinal endoscopic procedures. RESULTS: Twenty-nine patients with DL were identi- fied. Most of them were men with an average age of 71.5 years. Fifty-five percent of the patients received antiaggregatory or anticoagulant therapy. The most common location for DL was the stomach (51.7%). The main type of bleeding was oozing in 65.5% of cases. In 27.6% of cases, there was arterial (spurting) bleeding, and 6.9% of the patients presented with an adherent clot. A single endoscopic treatment was ap- plied to nine patients (31%), eight of them with adren- aline and one with argon, while 69% of the patients received combined treatment. Six patients (20.7%) presented with recurrent bleeding at a median of 4 d after endoscopy (interquartile range = 97.75). Within these six patients, the new endoscopic treatment ob- tained a therapeutic success of 100%. The presence of arterial bleeding at endoscopy was associated with a higher recurrence rate for bleeding (50% vs 33.3% for other type of bleeding) rP = 0.024, odds ratio (OR) = 8.5, 95% CI = 1.13-63.87]. The use of combined en- doscopic treatment prevented the recurrence of bleed- ing (10% vs 44.4% of single treatment) (P = 0.034, OR = 0.14, 95% CI = 0.19-0.99). CONCLUSION: Endoscopic treatment of DL is safe and effective. Adrenaline monotherapy and arterial (spurting) bleeding are associated with a high rate of bleeding recurrence.
文摘Two percent of gastrointestinal hemorrhages are caused by Dieulafoy's lesions, which are located in duodenum in only 15% of cases. There are no recommendations regarding the prime endoscopic treatment technique for this condition. A 61-year-old woman presented with melena without signs of hemodynamic instability. During an urgent upper endoscopy, blood oozing from the normal mucosa of the duodenum was seen and this was classified as a Dieulafoy's lesion. A mini-loop was opened at the rim of a transparent ligation chamber, at the end of the endoscope, and after aspiration of the lesion, closed and detached. Complete hemostasis was achieved without early or postponed complications. In every day clinical practice, mini-loop ligation is rarely used because of possible complications, such as site ulceration, organ perforation, re-bleeding and possible inexperience of the operator. To the best of our knowledge this is the first case of successful treatment of bleeding duodenal Dieulafoy's lesion by mini-loop ligation.
文摘Dieulafoy's lesion (DL) is a rare but important cause of obscure gastrointestinal bleeding that may be over-looked during diagnostic endoscopy. Mortality rates are similar to those of other causes for gastrointestinal bleeding. Diagnosis by upper endoscopy is the modal-ity of choice during acute bleeding. In the absence of active bleeding, the lesion resembles a raised nipple or visible vessel. There are no guidelines regarding effective selective therapy for DL, when diagnosed, en-doscopist experience is the major determinant of the treatment strategy. Following our strategy, an expert endoscopist with a skilled assistant should have a high rate of successful DL diagnosis when an obscured gas-trointestinal lesion is suspected. Cyanoacryltes com-pounds have been used successfully in management of Gastric varices and DLs. To our knowledge, there have been no previous reports regarding use of isoamyl-2-cyanoacrylate (AMCRYLATE ; Concord Drugs Ltd.,Hyderabad, India) as an effective therapy for gastric DL without serious complications. In our case study, Isoamyl-2-cyanoacrylate (AMCRYLATE) was effective and safe for treating DL. Surgical wedge resection of the lesion should be considered as a therapeutic option if endoscopic therapy fails.
文摘Although relatively uncommon, Dieulafoy's lesion is an important cause of acute gastrointestinal bleeding due to the frequent difficulty in its diagnosis; its tendency to cause severe, life-threatening, recurrent gastrointestinal bleeding; and its amenability to life-saving endoscopic therapy. Unlike normal vessels of the gastrointestinal tract which become progressively smaller in caliber peripherally, Dieulafoy's lesions maintain a large caliber despite their peripheral, submucosal, location within gastrointestinal wall. Dieulafoy's lesions typically present with severe, active, gastrointestinal bleeding, without prior symptoms; often cause hemodynamic instability and often require transfusion of multiple units of packed erythrocytes. About 75% of lesions are located in the stomach, with a marked proclivity of lesions within 6 cm of the gastroesophageal junction along the gastric lesser curve, but lesions can also occur in the duodenum and esophagus. Lesions in the jejunoileum or colorectum have been increasingly reported. Endoscopy is the first diagnostic test, but has only a 70% diagnostic yield because the lesions are frequently small and inconspicuous. Lesions typically appear at endoscopy as pigmented protuberances from exposed vessel stumps, with minimal surrounding erosion and no ulceration(visible vessel sans ulcer). Endoscopic therapy, including clips, sclerotherapy, argon plasma coagulation, thermocoagulation, or electrocoagulation, is the recommended initial therapy, with primary hemostasis achieved in nearly 90% of cases. Dual endoscopic therapy of epinephrine injection followed by ablative or mechanical therapy appears to be effective. Although banding is reportedly highly successful, it entails a small risk of gastrointestinal perforation from banding deep mural tissue. Therapeutic alternatives after failed endoscopic therapy include repeat endoscopic therapy, angiography, or surgical wedge resection. The mortality has declined from about 30% during the 1970's to 9%-13% currently with the advent of aggressive endoscopic therapy.
文摘AIM: To investigate retrospectively the clinical and endoscopic features of bleeding Dieulafoy's lesions and to assess the short- and long-term effectiveness of endoscopic treatment.METHODS: Twenty-three patients who had gastrointestinal bleeding from Dieulafoy's lesions underwent endoscopic therapy. Demographic data, mode of presentation, riskfactors for gastrointestinal bleeding, blood transfusion requirements, endoscopic findings, details of endoscopic therapy, recurrence of bleeding, and mortality rates were collected and analyzed retrospectively.RESULTS: Hemostasis was attempted by dextrose 50% plus epinephrine in 10 patients, hemoclipping in 8 patients,heater probe in 2 patients and ethanolamine oleate in 2 patients. Comorbid conditions were present in 17 patients (74%). Overall permanent hemostasis was achieved in 18 patients (78%). Initial hemostasis was successful with no recurrent bleeding in patients treated with hemoclipping, heater probe or ethanolamine injection. In the group of patients who received dextrose 50% plus epinephrine injection treatment, four (40%) had recurrent bleeding and one (10%) had unsuccessful initial hemostasis.Of the four patients who had rebleeding, three had unsuccessful hemostasis with similar treatment. Surgical treatment was required in five patients (22%) owing to uncontrolled bleeding, recurrent bleeding with unsuccessful retreatment and inability to approach the lesion. One patient (4.3%) died of sepsis after operation during hospitalization. There were no side-effects related to endoscopic therapy. None of the patients in whom permanent hemostasis was achieved presented with rebleeding from Dieulafoy's lesion over a mean long-term follow-up of 29.8 mo.CONCLUSION: Bleeding from Dieulafoy's lesions can be managed successfully by endoscopic methods, which should be regarded as the first choice. Endoscopic hemoclipping therapy is recommended for bleeding Dieulafoy's lesions.
文摘Dieulafoy lesions(DLs) are an uncommon cause of gastrointestinal bleeding, accounting for up to 2% of cases overall. They are largely under recognised and difficult to treat. Up to 95% occur in the stomach, and only case reports document their occurrence in the small bowel(SB). Little is known about their pathophysiology, although there have been associations made previously with chronic liver disease, thought to be due to the erosive effects of alcohol on the mucosa overlying the abnormally dilated vessels. We present a case series of 4 patients with a long duration of obscure gastrointestinal bleeding, who were diagnosed with small intestinal DLs and incidentally diagnosed with chronic liver disease. The histories describe the challenges in both diagnosis and treatment of small intestinal DLs. Our case series suggest a previously unreported link between chronic liver disease and SB DLs which may be due to anatomical vasculature changes or a shift in angiogenic factors as a consequence of portal hypertension or liver cirrhosis.
文摘Dieulafoy's lesion is an unusual cause of recurrent GI bleeding. This report describes a case of actively bleeding Dieulafoy's lesion of the small bowel in which the diagnosis was made by capsule endoscopy, followed by treatment with the use of push enteroscopy. The case illustrates that capsule endoscopy and enteroscopy are highly complementary in patients with small bowel diseases.
文摘AIM:To identify rates of occurrence,common clinical and endoscopic features,and to review the outcome of endoscopic management of Dieulafoy's lesions in the upper gastrointestinal (GI) tract in an urban community hospital setting. METHODS:Endoscopic data from esophagogastroduo denoscopies (EGDs),done at Wyckoff Heights Medical Center,Brooklyn,NY between 2000 and 2006 were reviewed to identify patients with Dieulafoy's lesions. Demographic data,medical history,examination findings,lab data,endoscopic findings and details of therapy for patients treated for Dieulafoy's lesions were reviewed retrospectively. RESULTS:Dieulafoy's lesions were documented to be the cause of bleeding in approximately 1% of patients presenting with upper gastrointestinal bleeding,while they were detected in only 2 patients when the indications for EGDs were different from active GI bleeding. When we analyzed EGDs performed in patients above age 65 years presenting with gastrointestinal bleeding,prevalence of Dieulafoy's lesions approached 10 percent. The most common location of the lesion was the body of stomach (7),followed by the cardia (4) and the esophagus (2). One patient had this lesion in the fundus and one patient in the duodenal apex. All patients were initially treated endoscopically with epinephrine injection,in eight cases heater probe was applied following epinephrine and endoscopic clips were applied in two cases. All but one of the patients did well in near and intermediate term follow-up (average follow-up period of 18 mo). One patient died of multi-organ failure during the same hospital stay. Average length hospital stay was 7 d.CONCLUSION:Community hospital gastroenterologists and endoscopists should be aware that Dieulafoy's lesions are an uncommon cause of upper GI bleeding among elderly patients. Early accurate diagnosis through emergent endoscopy and endoscopic therapy,especially in patients with multiple co-morbid conditions,can be very effective and life saving.

文摘BACKGROUND Bronchial Dieulafoy’s disease(BDD)is characterized by the erosion of an anomalous artery in the submucosa of the bronchus.The etiology of pediatric BDD is mainly congenital dysplasia of bronchus and pulmonary arteries,which is different from chronic inflammatory injury of the airway in adult patients.The internal thoracic artery,subclavian artery,and intercostal artery are known to be involved in the blood supply to the BDD lesion in children.CASE SUMMARY We report a case of BDD in a 4-year-old boy with recurrent hemoptysis for one year.Selective angiography showed a dilated right bronchial artery,and anastomosis of its branches with the right lower pulmonary vascular network.Bronchoscopy showed nodular protrusion of the bronchial mucosa with a local scar.Selective embolization of the bronchial artery was performed to stop bleeding.One month after the first intervention,the symptoms of hemoptysis recurred.A computed tomography angiogram(CTA)showed another tortuous and dilated feeding artery in the right lower lung,which was an abnormal ascending branch of the inferior phrenic artery(IPA).The results of angiography were consistent with the CTA findings.The IPA was found to be another main supplying artery,which was not considered during the first intervention.Finally,the IPA was also treated by microsphere embolization combined with coil interventional closure.During the one-year follow-up,the patient never experienced hemoptysis.CONCLUSION The supplying arteries of the bleeding lesion in children with BDD may originate from multiple different aortopulmonary collateral arteries,and the IPA should be considered to reduce missed diagnosis.CTA is a noninvasive radiological examination for the screening of suspected vessels,which shows a high coincidence with angiography,and can serve as the first choice for the diagnosis of BDD.
文摘Meckel diverticulum is an embryonic remnant of the Gastrointestinal duct which causes symptoms < 5% in the 2% population. Painless bleeding and abdominal pain are the most often reported symptoms. Dieulafoy lesion/dieulafoy-like lesion often cause upper gastrointestinal(GI) tract bleeding, but massive lower gastrointestinal bleeding is rare. We reported a 19-year-old male presented massive lower GI tract bleeding caused by Meckel diverticulum synchronous dieulafoy-like lesion.
文摘A Dieulafoy's lesion is a dilated,aberrant,submucosal vessel that erodes the overlying epithelium without evidence of a primary ulcer or erosion.It can be located anywhere in the gastrointestinal tract.We describe a case of massive gastrointestinal bleeding from Dieulafoy's lesions in the duodenum.Etiology and precipitating events of a Dieulafoy's lesion are not well known.Bleeding can range from being self-limited to massive life- threatening.Endoscopic hemostasis can be achieved with a combination of therapeutic modalities.The endoscopic management includes sclerosant injection,heater probe,laser therapy,electrocautery,cyanoacrylate glue,banding,and clipping.Endoscopic tattooing can be helpful to locate the lesion for further endoscopic re-treatment or intraoperative wedge resection.Therapeutic options for re-bleeding lesions comprise of repeated endoscopic hemostasis,angiographic embolization or surgical wedge resection of the lesions.We present a 63-yearold Caucasian male with active bleeding from the two small bowel Dieulafoy's lesions,which was successfully controlled with epinephrine injection and clip applications.
