Abstract: Objective To explore the feasibility of single-incision laparoscopic cholecystectomy using a three-dimensional (3D)
laparoscopic system. Methods Two patients with benign gallbladder disease with a history of recurrent abdominal pain were
selected to undergo the surgery. Gallstones were diagnosed by B ultrasound examination. All the operations were performed
through the umbilical incision with the 3D laparoscopic system. Results The 2 operations were completed successfully with a
operative time of 35 min and 50 min. Both of the patients were ambulatory 8 h after the surgery, began to have a normal diet 1
day after operation, and were discharged 2 days postoperatively without any clinical symptoms. Conclusions 3D
single-incision laparoscopic operation can well reveal the tissue anatomy in the operative field especially for some important
structures such as the Calot’s triangle with an improved safety compared to conventional laparoscopic operations.
