Port-sharing techniques for laparoscopic cholecystectomy and sleeve gastrectomy.

In Japan, the number of bariatric surgeries performed has remained low. Thus, concomitant laparoscopic cholecystectomy (LC) with laparoscopic sleeve gastrectomy (LSG) is still relatively uncommon, but is increasing. We developed new port-sharing techniques for LC and LSG, which we performed on 26 obese Japanese patients with gall bladder (GB) diseases, using the LSG trocar arrangement and one additional trocar. We performed LC first, and after exchanging a port for a liver retractor in the epigastrium, we then completed LSG. One patient with an anomalous extrahepatic bile duct required one additional port. The mean LC time was 55 min, and the transition to LSG just after LC was smooth in all the patients. One patient suffered postoperative intraperitoneal hemorrhage, which was managed conservatively. Concomitant LC with LSG using port-sharing techniques is feasible and safe for obese Japanese patients with GB diseases.
