Single-incision Versus Conventional Laparoscopic Cholecystectomy

To evaluate the feasibility and limitation of single-incision laparoscopic cholecystectomy (SILC), we performed a systematic literature search and 11 studies were included. SILC was successfully performed in 91.9% participants and conventional instruments were used mostly. Although longer operative time was required for this novel procedure than the conventional laparoscopic cholecystectomy, mean difference was 18.54 minutes (P=0.0001) and a learning curve was noted. There was no significant discrepancy in overall complications and severe complications (P=0.51 and 0.82, respectively). No difference in the length of hospital stay between the 2 groups was detected (P=0.09). No consensus has reached on the postoperative pain score between the 2 techniques. SILC with conventional instruments was a feasible and safe approach. It may be offered as an alternative for cholecystectomy in carefully selected patients.
