Acute cholecystitis due to strangulation of a floating gallbladder by the lesser omentum

Gallbladder strangulation caused by a fibrotic band due to chlamydia infection: A case report

Acute cholecystitis, a very common disease, is usually caused by gallstone obstruction of the cystic duct. Meanwhile, strangulated cholecystitis is extremely rare, and it develops when the gallbladder is strangled by a band. It is very similar to gallbladder torsion in terms of imaging findings and obstruction of blood and biliary flow, and it requires emergency surgery. We herein report a case of a 90-year-old woman with gallbladder strangulation caused by a fibrotic band due to a chlamydia infection, and we also reviewed some literature on strangulated cholecystitis.

Strangulated gallbladder caused by a tip of the omentum attached to the abdominal wall: a case report

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.

Floating gallbladder strangulation caused by the lesser omentum: report of a case

Strangulation of the gallbladder by the omentum is extremely rare. We report what to our knowledge is only the second documented case of strangulation of a floating gallbladder by the lesser omentum. A 61-year-old Japanese woman presented to a local hospital after the sudden onset right upper quadrant pain. Her clinical features suggested a gallbladder volvulus, and the patient was referred to our hospital for investigation and treatment. Ultrasonography and computed tomography showed no cholecystolithiasis, but the fundus and body of the gallbladder were markedly swollen without wall thickening, whereas the neck of the gallbladder was normal. A narrowed, twisted area was seen between the body and neck of the gallbladder. Based on these findings, gallbladder volvulus was diagnosed and she underwent emergency laparoscopic cholecystectomy. The fundus and body of the gallbladder were grossly necrotic. The narrowest part of the gallbladder was tightly strangulated by the lesser omentum, but the gallbladder neck was normal. Histopathologic examination of the resected gallbladder showed ischemic changes in the wall of the fundus and body. This case highlights that the clinical features and imaging findings of a gallbladder strangulated by the lesser omentum are similar to those of gallbladder volvulus and that a positive outcome is dependent on a correct diagnosis and prompt surgical management.

Strangulation Resulting from an Encasement of the Small Intestinal Loop by the Omentum without an Adhesive Band

The most common cause of small-bowel obstructions in adults is postoperative adhesions. However, strangulation of the small intestine in a patient without history of laparotomy is a rare condition. We experienced an unusual case of a small-bowel obstruction secondary to omental encasement in a patient without previous history of abdominal surgery or acute inflammatory process in the abdomen.
