Single-Institution Case Series of Patients Undergoing Cholecystectomy for Gallbladder Torsion

Abstract

Gallbladder torsion is one subtype of acute cholecystitis. Because of the very low incidence of the condition, there are few reports analyzing multiple cases of gallbladder torsion. The preoperative diagnosis is difficult and reported to be made in only 26% of patients. Herein, we report 6 consecutive cases of gallbladder torsion in 7 years and highlight the clinical and radiologic findings that facilitate preoperative diagnosis. Between 2005 and 2011, a total of 6 patients received a diagnosis of and were treated for gallbladder torsion in Toyonaka Municipal Hospital. A total of 5 patients received a diagnosis of gallbladder torsion or were suspected of having gallbladder torsion preoperatively, and 1 additional patient was diagnosed intraoperatively. The computed tomography findings of both excessive gallbladder swelling and rotation of the gallbladder fundus were observed in 5 patients, which were indicative findings of gallbladder torsion. The remaining 1 patient received a diagnosis intraoperatively. The twisted cystic duct and artery had been observed as a “whirl sign” preoperatively in 2 patients. Emergency cholecystectomy was performed: laparoscopic cholecystectomy was performed in 4 patients and open cholecystectomy in 2 patients. The patients treated by laparoscopic approach showed more rapid recovery and shorter postoperative hospital stay before discharge. The radiologic findings of both excessive gallbladder swelling and rotation of the gallbladder fundus are indicative of gallbladder torsion. The laparoscopic cholecystectomy approach could be considered the first choice for patients with gallbladder torsion.
