A Case of Laparoscopic Cholecystectomy(TANKO)for Gallbladder Cancer with Torsion

: Gallbladder torsion is comparatively rare. Gallbladder cancer is found in 1.5% of cases of acute cholecystitis. We report a case of laparoscopic cholecystectomy(TANKO)for gallbladder cancer with torsion. CASE: A 54-year-old woman with epigastric pain underwent enhanced computed tomography. Gallbladder torsion and a tumor at the gallbladder neck were suspected, and ascites was observed. She was diagnosed with gallbladder torsion, and surgery was performed the same day. Intraoperative findings: The gallbladder was movable, minimally attached to the liver bed, rotated 360°around the cystic duct and cystic artery, and appeared necrotic. The torsion was relieved and laparoscopic cholecystectomy(TANKO)was performed. We accidentally perforated the gallbladder and bile leaked out. COURSE: The patient did well postoperatively. Pathological diagnosis revealed gallbladder cancer. DISCUSSION: Gallbladder cancer with torsion has been reported in 14 cases, not including ours. Among these, none were performed using laparoscopic cholecystectomy(TANKO). We believe that laparoscopic cholecystectomy is appropriate for such cases, but the approach must be carefully considered because of the risk of perforation.
