Single-incision laparoscopic colectomy (SILC) requires only one umbilical port site and (depending on technique) a specimen extraction site. The aim of this study was the assessment of the available evidence for the comparison of SILC to conventional multi-port laparoscopic colectomy (MLC) in adult patients, in whom elective colectomy is indicated because of malignant or benign disease. First, previous meta-analyses on this topic were assessed. Secondly, a systematic review and meta-analysis of randomised controlled trials, was performed. ⋯ The currently available study results are too sparse to detect (or rule out) relevant differences between SILC and MLC. The quality of the current evidence is low, and the additional analysis of non-randomised data attempts, but does not solve this problem. SILC should still be considered as an experimental procedure, since the evidence of well-designed randomised controlled trials is too sparse to allow any recommendation.
