The misclassification of gastric antral vascular ectasia.

Background: Gastric antral vascular ectasia (GAVE) is characterized by angiodysplastic lesions and is a rare form of gastrointestinal bleeding. Given the multiple patterns, GAVE can be misclassified.

Aim: We analyzed the misclassification of GAVE among patients undergoing esophagogastroduodenoscopy (EGD).

Prevalence of metabolic syndrome in cirrhotics with gastric antral vascular ectasia.

Background And Aims: Gastric antral vascular ectasia (GAVE) is characterized by angliodysplastic lesions that can cause upper gastrointestinal bleeding (UGIB). The mechanism behind GAVE and its association with other diseases remains unknown. We investigated the association of metabolic syndrome in cirrhotic GAVE patients when compared to esophageal variceal hemorrhage (EVH) patients.

Postbariatric Surgery Hyperammonemia: A Rare Cause of Encephalopathy.

Hyperammonemic encephalopathy is an under-recognized and potentially fatal complication of Roux-en-Y gastric bypass surgery. We present a case of a 42-year-old woman with no known history of liver disease who experienced worsening encephalopathy 1 year after bariatric surgery. She presented with elevated ammonia and severe encephalopathy requiring intubation.

Orthotopic liver transplantation changes the course of gastric antral vascular ectasia: a case series from a transplant center.

Background And Aim: Gastric antral vascular ectasia (GAVE) is an important cause of upper gastrointestinal bleeding and anemia in patients with cirrhosis. The aim of our study was to evaluate the effect of orthotopic liver transplantation (OLT) on GAVE and associated anemia.

Patients And Methods: We performed a chart review and identified all cirrhotic patients with GAVE who underwent OLT at the University Of Alabama at Birmingham between 2005 and 2013.

Endoscopic closure of a gastrocolic fistula using the over-the-scope-clip-system.

Gastrointestinal (GI) defects such as fistulas and leaks can be potentially closed endoscopically using hemoclips and loops. However, hemoclips may not allow for closure of large defects and they do not exert enough tensile force to keep fibrotic defects larger than 5 mm approximated. Herein we present a case of successful endoscopic closure of a gastrocolic fistula in a severely malnourished patient with complex post-surgical upper GI anatomy.

Equivalent survival following liver transplantation in patients with non-alcoholic steatohepatitis compared with patients with other liver diseases.

Background: Orthotopic liver transplantation (LT) in non-alcoholic steatohepatitis (NASH) is increasing in parallel with the obesity epidemic.

Methods: This study retrospectively reviewed the clinical outcomes of LTs in NASH (n = 129) and non-NASH (n = 775) aetiologies carried out at a single centre between 1999 and 2009.

Results: Rates of 1-, 3- and 5-year overall survival in NASH (90%, 88% and 85%, respectively) were comparable with those in non-NASH (92%, 86% and 80%, respectively) patients.
