Small bowel vascular lesions, including angioectasia (AE), Dieulafoy’s lesion (DL) and arteriovenous malformation (AVM), are the most common causes of obscure gastrointestinal bleeding. Since AE are considered to be venous lesions, they usually manifest as a chronic, well-compensated condition. Subsequent to video capsule endoscopy, deep enteroscopy can be applied to control active bleeding or to improve anemia necessitating blood transfusion. Despite the initial treatment efficacy of argon plasma coagulation (APC), many patients experience re-bleeding, probably because of recurrent or missed AEs. Pharmacological treatments can be considered for patients who have not responded well to other types of treatment or in whom endoscopy is contraindicated. Meanwhile, a conservative approach with iron supplementation remains an option for patients with mild anemia. DL and AVM are considered to be arterial lesions;therefore, these lesions frequently cause acute life-threatening hemorrhage. Mechanical hemostasis using endoclips is recommended to treat DLs, considering the high re-bleeding rate after primary APC cauterization. Meanwhile, most small bowel AVMs are large and susceptible to re-bleeding therefore, they usually require surgical resection. To achieve optimal diagnostic and therapeutic approaches for each type of small bowel lesion, the differences in their epidemiology, pathology and clinical presentation must be understood. 展开更多

Continuous-flow left ventricular assist devices(CF-LVADs)have significantly improved outcomes for patients with end-stage heart failure when used as a bridge to cardiac transplantation or,more recently,as destination therapy.However,its implantations carries a risk of complications including infection,device malfunction,arrhythmias,right ventricular failure,thromboembolic disease,postoperative and nonsurgical bleeding.A significant number of left ventricular assist devices(LVAD)recipients may experience recurrent gastrointestinal hemorrhage,mainly due to combination of antiplatelet and vitamin K antagonist therapy,activation of fibrinolytic pathway,acquired von Willebrand factor deficiency,and tendency to develop small intestinal angiodysplasias due to increased rotary speed of the pump.Gastrointestinal bleeding in LVAD patients remains a source of increased morbidity including the need for blood transfusions,extended hospital stays,multiple readmissions,and overall mortality.Management of gastrointestinal bleeding in LVAD patients involves multidisciplinary approach in stabilizing the patients,addressing risk factors and performing structured endoluminal evaluation with focus on upper gastrointestinal tract including jejunum to find and eradicate culprit lesion.Medical and procedural intervention is largely successful and universal bleeding cessation occurs in transplanted patients. 展开更多

Splenic rupture is a rare complication of diagnostic and therapeutic gastrointestinal endoscopy procedures.Herein, we report for the first time a case of splenic rupture following therapeutic retrograde double-balloon enteroscopy, which occurred in an 85-year-old man who was treated for recurrent mid-intestinal bleeding that resulted from ileal angioectasia. This patient promptly underwent an operation and eventually recovered. 展开更多

AIM: To determine the test characteristics of community based video capsule endoscopy (VCE) in patients undergoing sequential VCE and double balloon enteroscopy (DBE). METHODS: Eighty-nine patients (34 females, 55 males, mean age 66) who underwent both VCE and DBE from 2008-2010 were retrospectively reviewed. Lesions detected at VCE were categorized. Capsule directed DBE followed and included 44 antegrade, 11 retrograde and 34 combined antegrade and retrograde procedures. Lesions detected were compared utilizing the McNemar’s test. RESULTS: Angioectasia detection with VCE was 25% and with DBE 35% (P 【 0.03) with a calculated sensitivity and specificity of 58% and 93% respectively. Polyps were detected by VCE in 22% and in DBE 20%, (P = 0.6), with a sensitivity and specificity for VCE of 61% and 87%. Small bowel diverticula were only seen in 1% of VCE but in 12% of DBE patients (P 【 0.002) with a calculated sensitivity and specificity of VCE of 9% and 100%. CONCLUSION: VCE would be moderately sensitiveand specific overall with considerable variation by lesion. Furthermore, VCE cannot be relied upon to diagnose small bowel diverticula. 展开更多

AIM To investigate visceral fat accumulation inassociation with the risk of small bowel angioectasia.METHODS: We retrospectively investigated 198consecutive patients who underwent both capsuleendoscopy and CT for investigation of obscuregastrointestinal bleeding (OGIB) from January 2009to September 2013. The visceral fat area (VFA) andsubcutaneous fat area were measured by CT, andinformation on comorbidities, body mass index, andmedications was obtained from their medical records.Logistic regression analysis was used to evaluateassociations.RESULTS: Capsule endoscopy revealed small bowelangioectasia in 18/198 (9.1%) patients with OGIB.Compared to patients without small bowel angioectasia,those with small bowel angioectasia had asignificantly higher VFA (96 ± 76.0 cm2 vs 63.4 ±51.5 cm2, P = 0.016) and a higher prevalence of livercirrhosis (61% vs 22%, P 〈 0.001). The proportionof patients with chronic renal failure was higher inpatients with small bowel angioectasia (22% vs 9%,P = 0.11). There were no significant differences insubcutaneous fat area or waist circumference. Theprevalence of small bowel angioectasia progressivelyincreased according to the VFA. Multivariate analysisshowed that the VFA [odd ratio (OR) for each 10-cm2increment = 1.1; [95% confidence interval (CI):1.02-1.19; P = 0.021] and liver cirrhosis (OR = 6.1,95%CI: 2.2-18.5; P 〈 0.001) were significant riskfactors for small bowel angioectasia.CONCLUSION: VFA is positively associated with the prevalence of small bowel angioectasia, for whichVFA and liver cirrhosis are independent risk factors inpatients with OGIB. 展开更多
