A prospective, randomized, single-blind trial of 5-mm versus 3-mm ports for laparoscopic cholecystectomy: is smaller better?

Background Single-incision laparoscopic cholecystectomy (SILC) is said to provide improved cosmesis with a reduction in postoperative pain, but SILC involves a change in operative technique. A single-blind, randomized controlled trial compared cosmetic outcomes and postoperative pain between 3- and 5-mm ports used for laparoscopic cholecystectomy (LC).
