Strangulation of the Floating Gallbladder by the Lesser Omentum

ABSTRACT

The strangulation of the gallbladder by the omentum is extremely rare. We report a unique case of acute cholecystitis due to the strangulation of a floating gallbladder by the lesser omentum. A 16-year-old male patient presented to a local hospital after the recurrent epigastric pain. The clinical features and image study suggested the gallbladder torsion, and the patient was referred for surgical treatment. Abdominal computed tomography showed no cholecystolithiasis, but the fundus and body of the gallbladder were markedly swollen with wall thickening, whereas the neck of the gallbladder was normal. Based on these findings, the gallbladder torsion was clinically diagnosed and he underwent laparoscopic cholecystectomy. The narrowed part of the gallbladder was tightly strangulated by the lesser omentum. So, strangulation of a floating gallbladder by the lesser omentum was finally diagnosed. We believe this case to be the third case of reported literatures in English.
