Single incision versus conventional multiport laparoscopic appendectomy: a systematic review and meta-analysis of randomized controlled trials.

Abstract

BACKGROUND:

The efficacy of single incision laparoscopic appendectomy (SILA) in comparison with conventional multiport laparoscopic appendectomy (CMLA) has not been conclusively determined.

METHODS:

A systematic literature review (Medline, EMBASE, Science Citation Index, and Cochrane Central Register of Controlled Trials) was performed. Meta-analyses of randomized controlled trials (RCTs) comparing SILA with CMLA were carried out by RevMan 5.0 software.

RESULTS:

Eleven RCTs comparing SILA and CMLA were included. Overall, 1,216 patients were operated on: 611 cases by SILA versus 605 cases by CMLA. Compared with CMLA, SILA was associated with increased procedural difficulty, prolonged procedural duration, shorter length of hospital stay, earlier return to normal activity and better cosmesis. There were no significant differences in postoperative pain scores and complication rates between SILA and CMLA.

CONCLUSION:

The current best evidence shows SILA holds the promise of improving postoperative recovery and cosmetic result with equal efficacy and safety, whereas it is associated with higher surgical difficulty with longer surgical time when compared with CMLA.
