title: Gallbladder herniation into the lesser sac through the foramen of Winslow: report of a case.
abstract: We report a case of gallbladder hernia into the lesser sac through the foramen of Winslow. The patient was a 90-year-old woman, admitted to hospital with obstructive jaundice. Computed tomography (CT) showed a left-deviated and remarkably enlarged gallbladder dragging the liver, and a dilated intrahepatic bile duct. The deviated gallbladder was thought to compress the common bile duct, causing the obstruction. Laparoscopic examination revealed gallbladder herniation into the lesser sac without a floating gallbladder; thus, we performed laparoscopic cholecystectomy. Herniation of the gallbladder is the rarest of all internal hernias and most reported cases have involved a floating gallbladder. The case we report here is therefore considered especially unusual.
