The most common site of ectopic pregnancy is the fallopian tube. The goal of this retrospective study is to address medical and conservative surgical management of unruptured fallopian tube EP as an effective manner to preserve tubes to prevent secondary infertility. This study was conducted between January 1, 2010, and April 30, 2024, in Ponni Hospital, Madurai. It included 319 women, out of 6248 pregnant women diagnosed with ectopic pregnancy by using an Inexecreen kit, trans-abdominal scan, trans-vaginal scan, and doubling of beta-human chorionic gonadotropin (β-HCG) in 48 hours and Magnetic Resonance Imaging (MRI). Medical and conservative surgical management were given to those patients effectively. Out of 319 patients, 62 patients (19.4%) had a ruptured ectopic pregnancy and underwent surgical treatment;257 patients (80.6%) had an unruptured ectopic pregnancy. The conservative medical management was provided to 257 patients. Out of 257 patients, 235 patients were treated by injecting methotrexate and folic acid rescue when the criteria were met. 14 patients had salpingostomy and injection methotrexate (Inj. Methotrexate) and inj. Prostaglandin F2 alpha was administered into the tubal wall to preserve tubes. 8 patients had a live ectopic pregnancy;for those patients, Inj. Methotrexate was injected into the gestational sac through ultrasound guidance. 225 out of 257 patients reached out to us to seek fertility treatment;the remaining 32 patients were not seeking fertility. All fertility-seeking patients had successful pregnancies. We lost follow-up of 12 patients in this study. Out of 213 patients who came for fertility treatment, a 76.1% success rate was achieved with live birth, the recurrent ectopic pregnancy rate was 13.6%, the miscarriage and stillbirth rates were 10.3%. 32 patients, who were not seeking fertility, had quality life without surgical scars for ectopic pregnancy and cost-effective treatment. 25 patients out of 32 had laparoscopic sterilization later, and 7 patients followed temporary contraception as per our advice. This clinical data was retrieved from medical records.展开更多

This condition also has an adverse effect on the fertility prospects of women who experience it. Objective: To determine the outcomes of subsequent spontaneous fertility after medical treatment of patients with methotrexate (MTX) in patients with ectopic pregnancy at two university teaching hospitals of Yaounde. Methodology: We carried out a cross-sectional study with retrospective data collection in two university teaching hospitals of Yaounde during a six years period from 1<sup>st</sup> January 2015 to 31<sup>st</sup> May 2021. Seventy records of patients who had medical treatment for ectopic pregnancy were included in this study. Statistical analysis was performed using SPSS. 23. The Chi-2 statistical test was used to compare qualitative variables. Binary logistic regression method was performed to identify independent risk factors associated with infertility after medical treatment of tubal ectopic pregnancy (TEP). The significance level was set at 0.05. Results: The mean age in our study population was 27.8 ± 3.8 years. According to the past medical history, 52.9% had a pelvic inflammatory disease (PID) and the most frequently germ found was C. trachomatis (47.1%). Almost 15% of our study population had previous surgery for EP. The median Fernandez score was 11 with a minimum score of 4 and a maximum score of 13. The route of administration of methotrexate was intramuscular in all our patients, and the single-dose protocol was used most frequently (58.6%). After medical treatment of the EP, we found a spontaneous conception rate of 58.6%. After multivariate analysis, we were unable to confirm that there was an association between a history of sexually transmitted infections (STIs) and fertility prognosis. Conclusion: The spontaneous fertility rate after medical management of EP was 58.6%, of which 73.2% were term pregnancies and 14.6% were recurrent ectopic pregnancies.展开更多

Methodology: This was a retrospective, descriptive study lasting two years (January 1, 2020 to December 31, 2022), carried out in the general surgery and gyneco-obstetrics departments of the Ignace Deen national hospital, Conakry University Hospital. We included all patients with a ruptured ectopic pregnancy who received surgical treatment during the study period. Results: We collected 13,524 cases of surgical interventions in the two services, among them, we recorded 89 cases or 0.66% GEUR. The average age of the patients was 24.26 years. Brides were the most represented with 80.96% of cases. Women practicing a liberal profession were 51.69% (n = 46) and housewives 26.97% (n = 24). Clinically, amenorrhea was noted in all patients, i.e. 100%, abdominal-pelvic pain in 95.2% (n = 85) of cases, metrorrhagia in 94.08% (n = 84), abdominal-pelvic sensitivity in 97.44% (n = 87) of cases and anemia in 85.39% of cases. The GEUR was ampullary in 69.66% (n = 62) cases. Salpingectomy was performed in 90.72% (n = 81). The surgical outcomes were satisfactory in 98.87% (n = 88) of cases. We recorded one case of surgical site infection. We have not recorded any deaths. The average length of hospitalization was 4 days. Conclusion: GEUR is relatively high in our context. A good understanding of the prognostic factors of GEUR, awareness and family planning could reduce GEUR.展开更多

His blood chemistry showed no infection with hepatitis B or C virus and no elevations of tumor markers or pancreatic hormones. Abdominal ultrasound showed an encapsulated, rather heterogeneous, hypoechoic tumor, 6.5 cm in maximum diameter, with a beak sign. Helical dynamic CT revealed an irregularly enhanced tumor with pooling of contrast medium in the delayed phase. Abdominal angiography showed a hypervascular tumor. With a tentative diagnosis of non-functional islet-cell tumor, the patient underwent resection of the pancreatic body and tail with splenectomy. The contour of the liver and its surface were normal. In microscopic examination, tumor cells arranged in a trabecular pattern with focal bile pigment resembling hepatocellular carcinoma (HCC). Immunohistochemically, these tumor cells were positivefor HEPPAR-1, CAM5.2, cytokeratin 18 and COX-2, but negative for MUC-1, and cytokeratins 7, 20 and 8. These results supported a diagnosis of HCC without any adenocarcinoma component. The patient is currently doing well without any signs of recurrence in either the remaining pancreas or liver three years after surgery. We report the rare case with ectopic HCC in the pancreas with a review of the literature.展开更多

Clinical data of patients who underwent IVF-ET treatment and had clinical pregnancy from 12463 cycles were retrospectively analyzed. Their findings of serum β-hCG test and transvaginal ultrasonography were also obtained during follow-up. These patients were divided into two groups according to the diagnosis accuracy of EP/HP: early diagnosis and misdiagnosis/delayed diagnosis. The results showed that the incidence of EP and HP was 3.8%(125/3286) and 0.8%(27/3286) respectively for IVF/ICSI-ET cycle, and 3.8%(55/1431) and 0.7%(10/1431) respectively for frozen-thawed embryo transfer(FET) cycle. Ruptured EP occurred in 28 patients due to initial misdiagnosis or delayed diagnosis. Related factors fell in 3 categories:(1) clinician factors: misunderstanding of patients' medical history, insufficient training in ultrasonography and unawareness of EP and HP;(2) patient factors: noncompliance with medical orders and lack of communication with clinicians;(3) complicated conditions of EP: atypical symptoms, delayed elevation of serum β-hCG level, early rupture of cornual EP, asymptomatic in early gestation and pregnancy of unknown location. All the factors were interwoven, contributing to the occurrence of EP and HP. It was concluded that complicated conditions are more likely to affect the diagnosis accuracy of EP/HP after IVF-ET. Transvaginal ultrasonography should be performed at 5 weeks of gestation. Intensive follow-up including repeated ultrasonography and serial serum β-hCG tests should be performed in patients with a suspicious diagnosis at admission.展开更多

Here, we reported the characterization of a soybean KNOX gene GmKNT1, which was highly homologous to Arabidopsis STM. The GmKNT1 was strongly expressed in roots, flowers and developing seeds. Its expression could be induced by IAA, ABA and JA, but inhibited by GA or cytokinin. Staining of the transgenic plants overexpressing GmKNT1-GUS fusion protein revealed that the GmKNT1 was mainly expressed at lobe region, SAM of young leaves, sepal and carpel, not in seed and mature leaves. Scanning electron microscopy (SEM) disclosed multiple changes in morphology of the epidermal cells and stigma. The transgenic Arabidopsis plants overexpressing the GmKNT1 showed small and lobed leaves, shortened internodes and small clustered inflorescence. The lobed leaves might result from the function of the meristems located at the boundary of the leaf. Compared with wild type plants, transgenic plants had higher expression of the SAM-related genes including the CUP, WUS, CUC1, KNAT2 and KNAT6. These results indicated that the GmKNT1 could affect multiple aspects of plant growth and development by regulation of downstream genes expression.展开更多

Methods Two hundred and fifteen women with ectopic pregnancy underwent operative laparoscopy. These patients were divided into two groups. The study group included 21 patients with shock and intraperitoneal hemorrhage more than 1000 mL, and control group included 194 patients, hemodynamically stable, with blood loss less than 1000 mL. Clinical data of perio-perative periods in two groups were retrospectively analyzed. Results All patients were tubal pregnancies. The occurrence rate of tubal rupture was higher in study group than in control group (80.95% vs. 15.98%, P < 0.001). Intraabdominal blood loss was significantly higher in study group than in control group (1900 mL vs. 300 mL, P < 0.001), and autologous blood transfusions were given to 95.24% and 9.3% of patients in study and control group, respectively (P < 0.001). Laparoscopic salpingectomy was performed on 85.7 % and 50.5% of patients in study and control group (P < 0.001). The operative time was somewhat longer in study group than that in control group (60 minutes vs. 45 minutes), but with no significant difference. All patients had no perioperative complications. Conclusion Operative laparoscopy in patients with hopovolemic shock can be safely and effectively performed by experi-enced laparoscopists with the aid of optimal anesthesia, advanced cardiovascular monitoring, and autologous blood transfusion.展开更多
文摘This editorial discusses the article written by Zheng et al that was published in the latest edition of the World Journal of Gastrointestinal Surgery.Our primary focus is on the causes,location,diagnosis,histological classification,and therapy of ectopic pancreas.Ectopic pancreas refers to the presence of pancreatic tissue that is situated in a location outside its usual anatomical placement,and is not connected to the normal pancreas in terms of blood supply or anatomical struc-ture.Currently,the embryological origin of ectopic pancreas remains uncertain.The most prevalent form of ectopic pancreatic is gastric ectopic pancreas.Endoscopic ultrasonography examination can visualize the morphological charac-teristics of the ectopic pancreatic lesion and pinpoint its anatomical location.The histological categorization of ectopic pancreas evolves.Endoscopic treatment has been widely advocated in ectopic pancreas.
文摘BACKGROUND An intrauterine device(IUD)is a contraceptive device placed in the uterine cavity and is a common contraceptive method for Chinese women.However,an IUD may cause complications due to placement time,intrauterine pressure and other factors.Ectopic IUDs are among the most serious complications.Ectopic IUDs are common in the myometrium and periuterine organs,and there are few reports of ectopic IUDs in the urinary bladder,especially in the anterior wall.CASE SUMMARY A 52-year-old woman was hospitalized due to a urinary bladder foreign body found via abdominal ultrasound and computed tomography(CT)examination.The patient had a 2-year history of recurrent abdominal distension and lower abdominal pain,accompanied by frequent urination,urgency,dysuria and other discomfort.Ultrasound examination revealed foreign bodies in the bladder cavity,with calculus on the surface of the foreign bodies.CT revealed a circular foreign body on the anterior wall of the urinary bladder,suggesting the possibility of an ectopic IUD.After laparoscopic exploration,an annular IUD was found in the anterior wall of urinary bladder,and an oval calculus with a diameter of approximately 2 cm was attached to the surface of the bladder cavity.The IUD and calculus were successfully and completely removed.The patient recovered well after surgery.CONCLUSION Abdominal ultrasound and CT are effective methods for detecting ectopic IUDs.The IUD is located in the urinary bladder and requires early surgical treatment.The choice of surgical method is determined by comprehensively considering the depth of the IUD in the bladder muscle layer,the situation of complicated calculus,the situation of intravesical inflammation and medical technology and equipment.
文摘The pancreatic development variations are relatively frequent but are often overlooked in clinical practice.This is due to the fact that they do not present with a distinct clinical picture and are usually asymptomatic.It also refers to the ectopic pancreatic tissue in the stomach.This anomaly can be diagnosed in any part of the digestive system,but it is mostly seen in the upper gastrointestinal tract,especially in the stomach,duodenum and jejunum.The management of this condition has evolved due to the development of minimally invasive procedures.

文摘BACKGROUND Digital subtraction angiography(DSA),the gold standard for the diagnosis of intracranial arteriovenous malformations(AVMs),can show clean nidus resection,leading to a perceived cure.Most cases of intracranial AVM recurrence have been reported in pediatric patients.The conventional understanding indicates that AVMs arise when abnormal blood vessels develop between the fourth and eighth weeks of embryonic development,which coincides with the typical period of blood vessel formation in the brain.As such,recurrent ectopic AVM are rare in adults.CASE SUMMARY Herein,we present the case of a 31-year-old adult with a history of an intracranial AVM originally diagnosed with a symptomatic de novo cerebellar AVM formation.Recurrence was observed five years following angiographically-confirmed excision of the initial AVM.DSA performed prior to initial AVM resection indicated no cerebellar abnormalities.Moreover,the recurrent arteries exhibited differences in arteries and draining veins.In addition to reporting this case,we analyzed six previously-reported adult patients with similar ectopic recurrent AVMs.These cases are summarized to review and explore the potential causes of ectopic AVM recurrence in adults,which increase the likelihood of acquired AVM.CONCLUSION The clinical course of the reported patients demonstrated the possibility of ectopic AVM recurrence in adults.The median time between the diagnosis of the initial AVM and the occurrence of ectopic recurrent AVM in adults was 11 years(range:5–20 years).Magnetic resonance imaging follow-up for more than 10 years may be required in adult AVM-treated patients.
文摘BACKGROUND Renal angiomyolipoma and renal cell carcinoma are the most common benign and malignant tumors of the kidney respectively,and the preoperative differential diagnosis is crucial due to the wide difference in treatment methods.Fat-poor renal angiomyolipoma is a relatively rare type of in renal angiomyolipoma.Its fat imaging features are not obvious,and it is easily misdiagnosed as renal cell carcinoma.CASE SUMMARY We report the case of a 41-year-old man who complained of osphyalgia.Subsequent abdominal computed tomography scans revealed that a heterogeneous mass was seen in the lower pole of the right kidney,with the size of about 53 mm×47 mm.And showed two right renal arteries,with the mass supplied by an ectopic vessel from the abdominal aorta.Fluorescent laparoscopic blockade of the right renal heterotopic artery and partial nephrectomy was performed.Based on histological and immunohistochemical findings,the tumor was diagnosed as fatpoor renal angiomyolipoma.CONCLUSION The use of fluorescent laparoscopy can effectively help intraoperative management,and the fluorescence pattern provided by intravenous indocyanine green can help suggest the final diagnosis,effectively guide the surgical decisionmaking,and avoid preoperative imaging diagnosis leading to nephrectomy for benign renal tumors,through fluorescent navigation of tumor supply vessel precise block,minimize the loss of renal function.
文摘An ectopic pregnancy (EP) is defined as any pregnancy that occurs outside the uterine cavity. The most common site of ectopic pregnancy is the fallopian tube. The goal of this retrospective study is to address medical and conservative surgical management of unruptured fallopian tube EP as an effective manner to preserve tubes to prevent secondary infertility. This study was conducted between January 1, 2010, and April 30, 2024, in Ponni Hospital, Madurai. It included 319 women, out of 6248 pregnant women diagnosed with ectopic pregnancy by using an Inexecreen kit, trans-abdominal scan, trans-vaginal scan, and doubling of beta-human chorionic gonadotropin (β-HCG) in 48 hours and Magnetic Resonance Imaging (MRI). Medical and conservative surgical management were given to those patients effectively. Out of 319 patients, 62 patients (19.4%) had a ruptured ectopic pregnancy and underwent surgical treatment;257 patients (80.6%) had an unruptured ectopic pregnancy. The conservative medical management was provided to 257 patients. Out of 257 patients, 235 patients were treated by injecting methotrexate and folic acid rescue when the criteria were met. 14 patients had salpingostomy and injection methotrexate (Inj. Methotrexate) and inj. Prostaglandin F2 alpha was administered into the tubal wall to preserve tubes. 8 patients had a live ectopic pregnancy;for those patients, Inj. Methotrexate was injected into the gestational sac through ultrasound guidance. 225 out of 257 patients reached out to us to seek fertility treatment;the remaining 32 patients were not seeking fertility. All fertility-seeking patients had successful pregnancies. We lost follow-up of 12 patients in this study. Out of 213 patients who came for fertility treatment, a 76.1% success rate was achieved with live birth, the recurrent ectopic pregnancy rate was 13.6%, the miscarriage and stillbirth rates were 10.3%. 32 patients, who were not seeking fertility, had quality life without surgical scars for ectopic pregnancy and cost-effective treatment. 25 patients out of 32 had laparoscopic sterilization later, and 7 patients followed temporary contraception as per our advice. This clinical data was retrieved from medical records.
文摘Background: Ectopic pregnancy is a major cause of maternal morbidity and mortality, estimated to occur in 1% - 2% of pregnancies worldwide. This condition also has an adverse effect on the fertility prospects of women who experience it. Objective: To determine the outcomes of subsequent spontaneous fertility after medical treatment of patients with methotrexate (MTX) in patients with ectopic pregnancy at two university teaching hospitals of Yaounde. Methodology: We carried out a cross-sectional study with retrospective data collection in two university teaching hospitals of Yaounde during a six years period from 1<sup>st</sup> January 2015 to 31<sup>st</sup> May 2021. Seventy records of patients who had medical treatment for ectopic pregnancy were included in this study. Statistical analysis was performed using SPSS. 23. The Chi-2 statistical test was used to compare qualitative variables. Binary logistic regression method was performed to identify independent risk factors associated with infertility after medical treatment of tubal ectopic pregnancy (TEP). The significance level was set at 0.05. Results: The mean age in our study population was 27.8 ± 3.8 years. According to the past medical history, 52.9% had a pelvic inflammatory disease (PID) and the most frequently germ found was C. trachomatis (47.1%). Almost 15% of our study population had previous surgery for EP. The median Fernandez score was 11 with a minimum score of 4 and a maximum score of 13. The route of administration of methotrexate was intramuscular in all our patients, and the single-dose protocol was used most frequently (58.6%). After medical treatment of the EP, we found a spontaneous conception rate of 58.6%. After multivariate analysis, we were unable to confirm that there was an association between a history of sexually transmitted infections (STIs) and fertility prognosis. Conclusion: The spontaneous fertility rate after medical management of EP was 58.6%, of which 73.2% were term pregnancies and 14.6% were recurrent ectopic pregnancies.
文摘Introduction: The aim of this study was to contribute to improving the quality of GEUR management in the general surgery department and in the maternity ward of the Ignace Deen national hospital, Conakry University Hospital. Methodology: This was a retrospective, descriptive study lasting two years (January 1, 2020 to December 31, 2022), carried out in the general surgery and gyneco-obstetrics departments of the Ignace Deen national hospital, Conakry University Hospital. We included all patients with a ruptured ectopic pregnancy who received surgical treatment during the study period. Results: We collected 13,524 cases of surgical interventions in the two services, among them, we recorded 89 cases or 0.66% GEUR. The average age of the patients was 24.26 years. Brides were the most represented with 80.96% of cases. Women practicing a liberal profession were 51.69% (n = 46) and housewives 26.97% (n = 24). Clinically, amenorrhea was noted in all patients, i.e. 100%, abdominal-pelvic pain in 95.2% (n = 85) of cases, metrorrhagia in 94.08% (n = 84), abdominal-pelvic sensitivity in 97.44% (n = 87) of cases and anemia in 85.39% of cases. The GEUR was ampullary in 69.66% (n = 62) cases. Salpingectomy was performed in 90.72% (n = 81). The surgical outcomes were satisfactory in 98.87% (n = 88) of cases. We recorded one case of surgical site infection. We have not recorded any deaths. The average length of hospitalization was 4 days. Conclusion: GEUR is relatively high in our context. A good understanding of the prognostic factors of GEUR, awareness and family planning could reduce GEUR.
文摘Cervical pregnancy is a rare clinical entity that accounts for less than 1% of all ectopic pregnancies.

The cornerstone in the management of cervical ectopic is early diagnosis by high index of suspension and a qualified sonographer. Management options for cervical ectopic pregnancies range from conservative drug treatment to radical hysterectomy. Over the last few years, the mortality and morbidity rates of ectopic pregnancies have been reduced.

文摘A 56-year-old man was found to have a pancreatic tail tumor. His blood chemistry showed no infection with hepatitis B or C virus and no elevations of tumor markers or pancreatic hormones. Abdominal ultrasound showed an encapsulated, rather heterogeneous, hypoechoic tumor, 6.5 cm in maximum diameter, with a beak sign. Helical dynamic CT revealed an irregularly enhanced tumor with pooling of contrast medium in the delayed phase. Abdominal angiography showed a hypervascular tumor. With a tentative diagnosis of non-functional islet-cell tumor, the patient underwent resection of the pancreatic body and tail with splenectomy. The contour of the liver and its surface were normal. In microscopic examination, tumor cells arranged in a trabecular pattern with focal bile pigment resembling hepatocellular carcinoma (HCC). Immunohistochemically, these tumor cells were positivefor HEPPAR-1, CAM5.2, cytokeratin 18 and COX-2, but negative for MUC-1, and cytokeratins 7, 20 and 8. These results supported a diagnosis of HCC without any adenocarcinoma component. The patient is currently doing well without any signs of recurrence in either the remaining pancreas or liver three years after surgery. We report the rare case with ectopic HCC in the pancreas with a review of the literature.
文摘BACKGROUND The ampulla of Vater is an opening at the confluence of the common bile duct and pancreatic duct.It is located in the second portion of the duodenum.An ectopic papilla of Vater is an anomalous termination.Few cases have been reported.We report the rare case of a man with an ectopic ampulla of Vater in the pylorus.CASE SUMMARY An 82-year-old man had experienced abdominal pain and fever with chills 1 d before his presentation.A computed tomography scan of the abdomen demonstrated dilatation of the common bile duct approximately 2.2 cm in width.Gas retention was found in his intrahepatic ducts.Acute cholangitis with pneumobilia was identified,and he was hospitalized.Esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography disclosed no ampulla of Vater in the second portion of the duodenum.Moreover,a capsule-like foreign body(pharmaceutical desiccant)approximately 1 cm×2 cm in size was found at the gastric antrum and peri-pyloric region.After the foreign body was removed,one orifice presented over the pyloric ring in the stomach,a suspected ectopic ampulla of Vater.Subsequently,sludge in the common bile duct was cleaned,and balloon dilatation was performed.The general condition improved daily.The patient was discharged in a stable condition and followed in our outpatient department.CONCLUSION This case involved an ampulla of Vater in an unusual location.Endoscopic retrograde cholangiopancreatography with balloon dilatation is the main treatment recommended and performed.

文摘This study examined the misdiagnosis and delayed diagnosis factors for ectopic pregnancy(EP) and heterotopic pregnancy(HP) after in vitro fertilization and embryo transfer(IVF-ET) in an attempt to reduce the diagnostic error. Clinical data of patients who underwent IVF-ET treatment and had clinical pregnancy from 12463 cycles were retrospectively analyzed. Their findings of serum β-hCG test and transvaginal ultrasonography were also obtained during follow-up. These patients were divided into two groups according to the diagnosis accuracy of EP/HP: early diagnosis and misdiagnosis/delayed diagnosis. The results showed that the incidence of EP and HP was 3.8%(125/3286) and 0.8%(27/3286) respectively for IVF/ICSI-ET cycle, and 3.8%(55/1431) and 0.7%(10/1431) respectively for frozen-thawed embryo transfer(FET) cycle. Ruptured EP occurred in 28 patients due to initial misdiagnosis or delayed diagnosis. Related factors fell in 3 categories:(1) clinician factors: misunderstanding of patients' medical history, insufficient training in ultrasonography and unawareness of EP and HP;(2) patient factors: noncompliance with medical orders and lack of communication with clinicians;(3) complicated conditions of EP: atypical symptoms, delayed elevation of serum β-hCG level, early rupture of cornual EP, asymptomatic in early gestation and pregnancy of unknown location. All the factors were interwoven, contributing to the occurrence of EP and HP. It was concluded that complicated conditions are more likely to affect the diagnosis accuracy of EP/HP after IVF-ET. Transvaginal ultrasonography should be performed at 5 weeks of gestation. Intensive follow-up including repeated ultrasonography and serial serum β-hCG tests should be performed in patients with a suspicious diagnosis at admission.
文摘AIM:To study the clinical,endoscopic,sonographic,and cytologic features of ectopic pancreas(EP).METHODS:This was a retrospective study performedat an academic referral center including two hospitals.Institutional review board approval was obtained.Patients referred to the University Hospital or Denver Health Medical Center Gastrointestinal Endoscopy Lab for gastroduodenal subepithelial lesions(SEL)with a final diagnosis of EP between January 2009and December 2013 were identified.Patients in this group were selected for the study if they underwent endoscopic ultrasound(EUS)with fine-needle aspiration(FNA)or deep biopsy.A review of the medical record was performed specifically to review the following information:presenting symptoms,endoscopic and EUS findings,computed tomography or magnetic resonance imaging findings,pathology results,procedure-related adverse events,and subsequent treatments after EUSFNA.EUS with FNA or deep submucosal biopsy was performed in all patients on an outpatient basais by one of two physicians(Attwell A,Fukami N).Review of all subsequent clinic notes and operative reports was performed in order to determine follow-up and final diagnoses.RESULTS:Between July 2009 and December 2013,10patients[3 males,7 females,median age 52(26-64)years]underwent EUS for a gastroduodenal SEL and were diagnosed with EP.One patient was symptomatic.Six(60%)lesions were in the antrum,3(30%)in the body,and 1(10%)in the duodenum.A mucosal dimple was noted in 6(60%).Mean lesion size was 17(8-25)mm.Gastrointestinal wall involvement:muscularis mucosae,10%;submucosa,70%;muscularis propria,60%;and serosa,10%.Nine(90%)lesions were hypoechoic and 5(50%)were homogenous.A duct was seen in 5(50%).FNA was attempted in 9(90%)and successful in 8(80%)patients after 4(2-6)passes.Cytology showed acini or ducts in 7 of 8(88%).Superficial biopsies in 7 patients(70%)showed normal gastric mucosa.Deep endoscopic biopsies were taken in 2 patients and diagnostic in one.One patient(10%)developed pancreatitis after EUS-FNA.Two patients(20%)underwent surgery to relieve symptoms or confirm the diagnosis.The main limitation of the study was the fact that it was retrospective and performed at a single medical center.CONCLUSION:EUS features of EP include antral location,mucosal dimple,location in layers 3-4,and lesional duct,and FNA or biopsy is accurate and effective.
文摘AIM:To evaluate the efficacy of human thrombin in the treatment of bleeding gastric and ectopic varices.METHODS:Retrospective observational study in a Tertiary Referral Centre.Between January 1999-October 2005,we identified 37 patients who were endoscopically treated with human thrombin injection therapy for bleeding gastric and ectopic varices.Patient details including age,gender and aetiology of liver disease/segmental portal hypertension were documented.The thrombin was obtained from the Scottish National Blood Transfusion Service and prepared to give a solution of 250 IU/mL which was injected via a standard injection needle.All patient case notes were reviewed and the total dose of thrombin given along with the number of endoscopy sessions was recorded.Initial haemostasis rates,rebleeding rates and mortality were catalogued along with the incidence of any immediate complications which could be attributable to the thrombin therapy.The duration of follow up was also listed.The study was conducted according to the United Kingdom research ethics guidelines.RESULTS:Thirty-seven patients were included.33 patients(89%) had thrombin(250 U/mL) for gastric varices,2(5.4%) for duodenal varices,1 for rectal varices and 1 for gastric and rectal varices.(1) Gastric varices,an average of 15.2 mL of thrombin was used per patient.Re-bleeding occurred in 4 patients(10.8%),managed in 2 by a transjugular intrahepatic portosystemic shunt(TIPSS)(one unsuccessfully who died) and in other 2 by a distal splenorenal shunt;(2) Duodenal varices(or type 2 isolated gastric varices),an average of 12.5 mL was used per patient over 2-3 endoscopy sessions.Re-bleeding occurred in one patient,which was treated by TIPSS;and(3) Rectal varices,an average of 18.3 mL was used per patient over 3 endoscopy sessions.No re-bleeding occurred in this group.CONCLUSION:Human thrombin is a safe,easy to use and effective therapeutic option to control haemorrhage from gastric and ectopic varices.

文摘Plant morphology is specified by leaves and flowers, and the shoot apical meristem (SAM) defines the architecture of plant leaves and flowers. Here, we reported the characterization of a soybean KNOX gene GmKNT1, which was highly homologous to Arabidopsis STM. The GmKNT1 was strongly expressed in roots, flowers and developing seeds. Its expression could be induced by IAA, ABA and JA, but inhibited by GA or cytokinin. Staining of the transgenic plants overexpressing GmKNT1-GUS fusion protein revealed that the GmKNT1 was mainly expressed at lobe region, SAM of young leaves, sepal and carpel, not in seed and mature leaves. Scanning electron microscopy (SEM) disclosed multiple changes in morphology of the epidermal cells and stigma. The transgenic Arabidopsis plants overexpressing the GmKNT1 showed small and lobed leaves, shortened internodes and small clustered inflorescence. The lobed leaves might result from the function of the meristems located at the boundary of the leaf. Compared with wild type plants, transgenic plants had higher expression of the SAM-related genes including the CUP, WUS, CUC1, KNAT2 and KNAT6. These results indicated that the GmKNT1 could affect multiple aspects of plant growth and development by regulation of downstream genes expression.
文摘Ectopic varices are unusual with portal hypertension and can involve any site along the digestive tract outside the gastroesophageal region. Hemorrhage from ectopic varices generally are massive and life threatening.Diagnosis of ectopic varices is difficult and subsequent treatment is also difficult; the optimal treatment has not been established. Recently, interventional radiology and endoscopic treatments have been carried out successfully for hemorrhage from ectopic varices.
文摘Ectopic adrenal cortical neoplasms are extremely rare. Ectopic adrenocortical tissue can be found in locations such as the celiac axis,the broad ligament,the adnexa of the testes,and the spermatic cord;however,they rarely involve the stomach.We report an unusual case of a patient with an ectopic adrenal cortical adenoma in the gastric wall.The patient was a 72-year old female admitted to our hospital with upper abdominal discomfort.Physical examination revealed tenderness below the xiphoid process.Both computed tomography and fibergastroscopy revealed a mass on the lesser curvature side of the gastric antrum;it was initially diagnosed as a gastric stromal tumor.After adequate preparation,the patient underwent surgery.During the procedure,we found a 30 mm×30 mm mass with medium density in the lesser curvature near the gastric antrum within the serosa.Following immunohistochemistry examination, we corrected the diagnosis to an ectopic adrenal cortical adenoma;the tumor was nonfunctional.
文摘Objective To evaluate the feasibility and safety of operative laparoscopy for ectopic pregnancy with hypovolemic shock. Methods Two hundred and fifteen women with ectopic pregnancy underwent operative laparoscopy. These patients were divided into two groups. The study group included 21 patients with shock and intraperitoneal hemorrhage more than 1000 mL, and control group included 194 patients, hemodynamically stable, with blood loss less than 1000 mL. Clinical data of perio-perative periods in two groups were retrospectively analyzed. Results All patients were tubal pregnancies. The occurrence rate of tubal rupture was higher in study group than in control group (80.95% vs. 15.98%, P < 0.001). Intraabdominal blood loss was significantly higher in study group than in control group (1900 mL vs. 300 mL, P < 0.001), and autologous blood transfusions were given to 95.24% and 9.3% of patients in study and control group, respectively (P < 0.001). Laparoscopic salpingectomy was performed on 85.7 % and 50.5% of patients in study and control group (P < 0.001). The operative time was somewhat longer in study group than that in control group (60 minutes vs. 45 minutes), but with no significant difference. All patients had no perioperative complications. Conclusion Operative laparoscopy in patients with hopovolemic shock can be safely and effectively performed by experi-enced laparoscopists with the aid of optimal anesthesia, advanced cardiovascular monitoring, and autologous blood transfusion.
