Single-Incision Laparoscopic Cholecystectomy Using Conventional Laparoscopic Instruments and Comparison with Three-Port Cholecystectomy.

Single-incision laparoscopic surgery also known as laparo-endoscopic single-site surgery for cholecystectomy is performed using a single umbilical skin incision through which a laparoscope and two instruments are introduced. It is virtually a "scarless" surgery. The present study was undertaken to evaluate the efficacy of single-incision laparoscopic cholecystectomy using conventional instruments and compare it with three-port laparoscopic cholecystectomy.
