Trajectory of NAFLD characteristics after Roux-en-Y gastric bypass: a five-year historical cohort study.

Background: The long-term effects of bariatric surgery on the course of non-alcoholic fatty hepatopathy (NAFLD) are not fully understood.

Objective: To analyze the evolution of NAFLD characteristics through noninvasive markers after Roux-en-Y gastric bypass (RYGB) over a five-year period.

Design And Setting: Historical cohort study; tertiary-level university hospital.

Rendez-Vous laparoendoscopic after ERCP failure in patient with Billroth II gastrectomy.

Endoscopic retrograde cholangiopancreatography (ERCP) is the treatment of choice in patients with choledocholithiasis. However,despite its high success rate, in some cases it is not successful, requiring alternative therapy. Billroth II partial gastrectomy is a condition associated with an important failure rate of ERCP.

Biliary ileus: case report.

Biliary ileusis a uncommon cause of mechanical bowel obstruction, affecting older adult patients who often have other significant medical conditions. It is caused by intestinal impaction of a gallstone that enters the bowel via a cholecysto-enteric fistula. The mortality rate is considerable, ranging between 12 and 27%.

Laparoendoscopic rendez-vous: a safe alternative to the treatment of choledocholithiasis.

The choice treatment for choledocholithiasis when associated with lithiasic cholecystitis is endoscopic retrograde cholangiopancreatography (ERCP). However, in some cases this therapeutic fails, which requires an alternative method to extract the stones. The surgical approach tends to be the next step, but it is related to greater complexity of achievement and higher complications rates.

Perforated Meckel's diverticulum.

We report a patient with diffuse peritonitis due to perforation of Meckel's diverticulum. This patient was referred to the operating room and underwent bowel resection segment encompassing the area of the diverticulum and terminoterminal primary enteroanastomosis on two levels with good evolution. The diverticulum complications are often related to the presence of ectopic mucosa, specially the gastric and pancreatic type.
