Single-incision laparoscopic cholecystectomy versus traditional laparoscopic cholecystectomy performed by a single surgeon: findings of a randomized trial

Abstract

Purposes

Traditional laparoscopic cholecystectomy (TLC) is performed widely; however, single-incision cholecystectomy (SILC) has been proposed as a better and less traumatic procedure.

Methods

In this prospective, double-blinded, randomized study, patients were randomized to undergo either elective SILC or TLC. The primary endpoint was the level of pain after surgery and the secondary endpoints were complications, cosmetic outcomes, and patient satisfaction.

Results

A total of 59 patients were enrolled (SILC, n = 30; TLC, n = 29). The median operative time was longer for the SILC group (55 vs. 40 min; P < 0.0001). Patients in the SILC group had a lower median VAS pain score 4 h after surgery (20 mm for the TLC group vs. 15 mm for the SILC group). Complications were distributed equally. Twenty-eight of the 30 patients in the SILC group vs. 23 of the 29 patients in the TLC group were very satisfied with their operation (P = 0.032). The cosmetic results of SILC were better than those of TLC, with visible scars in 21 patients from the TLC group vs. 3 patients from the SILC group (P = 0.0001).

Conclusions

We found SILC to be a safe, feasible, and adaptable surgical technique. The pain scores at 4 h were significantly better for SILC than for TLC.
