Anatomical basis for the low incidence of internal hernia after a laparoscopic Roux-en-Y gastric bypass without mesenteric closure.

Background: Different techniques have been designed to reduce the rate of internal hernia (IH) after laparoscopic bariatric surgery, and mesenteric closure is possibly the most controversial. We propose a laparoscopic Roux-en-Y gastric bypass (LRYGB) procedure without mesenteric closure with several specific technical details to avoid IH. To support this view, we have reviewed the outcome of our LRYGB patients and have carried out an anatomical study on cadavers.

[Adenocarcinoma of the gallbladder as a histopathological finding after cholecystectomy].

Objective: We wanted to determine the incidence in our population of gallbladder adenocarcinoma based on a histopathologic study done after cholecystectomy in patients with a diagnosis of gallstones.

Material And Methods: We made a census-type study during the last 3 years that included a total of 4548 gallbladders. Histopathologic results were analyzed and recollected in an established format.
