Abstract
Strangulation of the gallbladder associated with the omentum is extremely rare and, to our knowledge, only two cases have been previously reported. The patient was a 91-year-old female who presented to our emergency room with a chief complaint of upper abdominal pain. Computed tomography imaging revealed a gourd-shaped gallbladder with biphasic appearance divided clearly at the body. In the fundus side, the wall of the gallbladder was oedematous and thickened, while the neck side was intact. On the second day after onset, a laparoscopic cholecystectomy was performed. A tip of the omentum encircling the gallbladder was adhered to the abdominal wall and was strangling the gallbladder. By cutting the omentum at the attachment site, the strangulation was released. Laparoscopic cholecystectomy was performed, and the patient was discharged with an uneventful course. We experienced an extremely rare case of strangulated gallbladder caused by a tip of the omentum attached to the abdominal wall.
