Introduction: Situs inversus totalis is a rare congenital condition that involves sagittal mirroring of all thoracic and abdominal organs. The mirrored anatomy poses a challenge to the surgeon performing intra-abdominal surgery. Several laparoscopic techniques have been described for cholecystectomy in these patients.
Case Description: A 50-year-old woman with situs inversus totalis presented with left upper quadrant pain, cholelithiasis, and clinical findings consistent with acute cholecystitis. She underwent laparoscopic cholecystectomy with a single-site, “marionette” technique. This entailed a single periumbilical incision with 2 trocars (for camera and dissecting instrument) with suture suspension of the infundibulum, body, and fundus of the gallbladder, to facilitate manipulation and visualization.
Discussion: Several case reports have described safe completion of laparoscopic cholecystectomy in the setting of situs inversus totalis by using either mirroring of the traditional 4-port arrangement or a single port, multichannel apparatus. This article describes a single-site, marionette technique that circumvents many of the ergonomic and technical short- comings of approaches described elsewhere.
