Randomized Controlled Trial Multicenter Study Comparative Study
Randomized clinical study for assessment of incision characteristics and pain associated with LESS versus laparoscopic cholecystectomy.
Laparoendoscopic single-site surgery (LESS) has emerged as a technique that uses a natural scar, the umbilicus, within which a multiple-entry portal is placed into a 3.0-4.0-cm single incision to perform operations. The objective of this study was to compare incision size, wound complications, and postoperative pain of LESS compared with those of laparoscopic cholecystectomy (LC). ⋯ The LESS single-port (SP) operations demand a bigger incision than LC surgery. However, there were no differences in healing, wound infections, and hernia development. We found a tendency of less postoperative pain associated with LESS/SP than with LC.
