Situs inversus totalis is a rare anatomical anomaly of internal viscera in the reversed position. It is estimated to occur in 1 in 5,000-20,000 birth annually. Symptomatic cholecystitis in patients with situs inversus totalis renders diagnostic and therapeutic challenges. Because the routine preoperative examination may not detect this anatomical variation and there are limited medical literatures of cholecystectomy in patients with situs inversus totalis, it may surprise surgeons during operation and lead to higher surgical complications. Here we presented a case report of laparoscopic cholecystectomy of left- sided gallbladder in patient with situs inversus totalis. The gallbladder was situated between segment III and IV and to the left of the falciform ligament. The cystic duct jointed the common bile duct (CBD) from the right side. The successful laparoscopic cholecystectomy was performed and patient was discharged home on the same day. We also discussed the unpredictable confluence of cystic duct into the common bile duct, the key procedures for safe laparoscopic cholecystectomy for left-sided gallbladder in situs inversus totalis and reviewed the relevant medical literatures.
