Single-Incision Laparoscopic Cholecystectomy Using a Dome-Down Approach for a Patient with Left-Sided Gallbladder

Abstract

True left-sided gallbladder (sinistroposition) is a rare anatomic anomaly in which the gallbladder is found to the left of the falciform ligament under the left lobe of the liver. Though uncommon, it is important for the surgeon to identify this anomaly because the ductal anatomy is unique and the surgery is technically challenging. Multiple case reports have documented safe management of sinistroposition encountered during conventional laparoscopic cholecystectomy. We present a case of sinistroposition encountered during a single-incision laparoscopic cholecystectomy. We conclude that this single-site laparoscopic technique is not only safe when sinistroposition is encountered, but it may actually provide certain ergonomic benefits for surgeons.
