Herniation of the gallbladder through the foramen of Winslow.

A rare case of herniation of the gallbladder through the foramen of Winslow is presented. There are only six surgically proven previously reported cases. This condition should be suspected where symptoms suggest gallbladder disease in the presence of normal functioning gallbladder. A simultaneous cholecystogram and an upper gastrointestinal study is necessary to confirm the diagnosis. A cholecystectomy with plication of the foramen of Winslow is the suggested treatment.
