Comparison of postoperative pain between single-incision laparoscopic cholecystectomy and conventional laparoscopic cholecystectomy: prospective case-control study.

Background: Single-incision laparoscopic cholecystectomy (SILC) is an emerging technique used in cholecystectomy. Nevertheless, studies on the difference in postoperative pain between SILC and conventional laparoscopic cholecystectomy are lacking in the literature.

Patient And Methods: From August 2009 to July 2010, 20 consecutive patients who underwent SILC (SILC group) were compared with a prospective cohort of 20 patients who underwent conventional 4-port laparoscopic cholecystectomy (LC group) during the same period.
