"Comparison of Pick'n Roll Single-incision Laparoscopic Cholecystectomy Technique, and Laparoscopic Cholecystectomy"

Classical four port laparoscopic cholecystectomy

"SILC-PR was performed by the intraumbilical single port technique. A 10-mm, 30º scope was used. The surgeon was elevated gallbladder fundus with left hand using grasper in whole operation. If required, infindibulum was freed with monopolar hook. A 2.0 straight needle was inserted through the right of the falciform ligament, grasped with a laparoscopic needleholder using by surgeon's right hand, and passed through the Hartmann's pouch at the lowest point. To allow free manipulation, the passing suture with needle was turned around the suture to form a half-knot. The needle was passed back out from the right of the midclavicular line. An assistant was grasped two ends of the suture and with the help of right or left hand dominant pulling tension, critical view of safety was provided"
