Laparoscopic cholecystectomy is a broadly used technique for gallbladder treatment. However, situs inversus, a rare anomaly, is reportedly difficult to treat by conventional laparoscopic cholecystectomy. A 36-year-old woman with chronic cholecystitis and multiple gallstones was found to have dextrocardia on a chest X-ray. Magnetic resonance imaging demonstrated situs inversus, cholecystitis, and cholelithiasis. We successfully performed laparoscopic cholecystectomy using our modified technique, which mainly involved a left-handed operation and adjustment of the port positions. This case will be very instructive for right-handed surgeons in the management of cholelithiasis by laparoscopic cholecystectomy in patients with situs inversus.
