Single incision laparoscopy versus conventional multiport laparoscopy for colorectal surgery: a systematic review and meta-analysis.

There has been an increase in colorectal cancer resections worldwide and in the UK. Initially conducted as an open procedure, this was replaced with the conventional multiport technique. Laparoscopic colectomy became the standard surgical technique in 1991. With innovation in surgical technology, single incision laparoscopy (SIL) has attracted more attention as the possible next step in colorectal resection. The aim of this review was to compare outcomes between SIL and conventional laparoscopy (CL). A literature search was carried out in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. The PubMed A total of 11 RCTs were extracted with 1,370 patients (686 SIL, 684 CL). There was no significant difference between SIL and CL for operative time (standardised mean difference [SMD]: 0.01, 95% confidence interval [CI]: -0.19 to 0.22, z=0.11, SIL can be considered a safe alternative to CL if performed by experienced surgeons.
