Drain After Laparoscopic Cholecystectomy for Acute Calculous Cholecystitis. A Pilot Randomized Study.

Drainage after laparoscopic cholecystectomy (LC) for acute calculous cholecystitis (ACC) is used without evidence of its efficacy. The present pilot study was designed to address this issue. After laparoscopic gallbladder removal, 15 patients were randomized to have a drain positioned in the subhepatic space (group A) and 15 patients to have a sham drain (group B).

Prevalence of adenoma of gallbladder, ultrasonographic and histological assessment in a retrospective series of 450 cholecystectomy.

Background: Adenomyomas of the gallbladder are difficult to examine during standard ultrasound examination of the abdomen. They sometimes undergo malignant transformation and their optimal management still remains a problem. The authors have aimed to investigate the ultrasonographic and histopathological prevalence of gallbladder adenomyomas focusing on the diagnostic performance of ultrasound examination.
