The Role of Routine Upper Gastrointestinal Endoscopy Before Bariatric Surgery.

Background: Obesity remains a major health concern for which surgery has proven to be the most effective treatment in the long term. Routine upper gastrointestinal endoscopy (UGE) is recommended before surgery, but few studies have evaluated its impact on postoperative complications.

Methods: We studied a cohort of 613 patients submitted to UGE before being listed for bariatric surgery between May 2004 and May 2015.

Role of endoscopy after an acute episode of diverticulitis: analysis of a cohort of Portuguese patients from a tertiary referral center.

Introduction: Acute diverticulitis represents an inflammatory process originating in a colonic diverticulum. Although acute diverticulitis usually follows a benign course - uncomplicated diverticulitis (UCD), up to 25% may develop complicated diverticulitis (CD) including abscesses, fistulas, strictures, and perforation. Current guidelines recommend performing colonoscopy after an episode of acute diverticulitis to rule out colorectal cancer (CRC).

Three decades of hepatitis B control with vaccination.

Hepatitis B virus (HBV) continues to represent a major health problem and can lead to acute liver failure, acute hepatitis, chronic carriership, chronic hepatitis of HBV, liver cirrhosis, liver cancer, liver transplantation and death. There is a marked difference in the geographic distribution of carriers. More than 240 million people worldwide are chronic HBV carriers.

Outcomes of endoscopic management of primary and refractory postcholecystectomy biliary leaks in a multicentre review of 178 patients.

Background: Biliary leaks have been treated with endoscopic management using different techniques with conflicting results. Furthermore the appropriate rescue therapy for refractory leaks has not been established. We evaluated the clinical effectiveness of initial endotherapy for postcholecystectomy biliary leaks using an homogenous approach (sphincterotomy + placement of a 10-French plastic stent) in a large series of patients as well as the optimal and efficacy of rescue endotherapy for refractory biliary leaks.

A non-randomized study in consecutive patients with postcholecystectomy refractory biliary leaks who were managed endoscopically with the use of multiple plastic stents or fully covered self-expandable metal stents (with videos).

Background: Endoscopic management of postcholecystectomy biliary leaks is widely accepted as the treatment of choice. However, refractory biliary leaks after a combination of biliary sphincterotomy and the placement of a large-bore (10F) plastic stent can occur, and the optimal rescue endotherapy for this situation is unclear.

Objective: To compare the clinical effectiveness of the use of a fully covered self-expandable metal stent (FCSEMS) with the placement of multiple plastic stents (MPS) for the treatment of postcholecystectomy refractory biliary leaks.

Life history of the land snail Habroconus semenlini (Stylommatophora: Euconulidae) under laboratory conditions.

Habroconus semenlini is a micro-terrestrial gastropod native to South America. There are no previous studies on its biology. We studied its pattern of growth, fertility and lifespan under laboratory conditions.
