Systematic review and meta-analysis of single-incision versus conventional multiport laparoscopic splenectomy.

Abstract

Background:There is no consensus that single-incision laparoscopic surgery splenectomy (SILS-SP) is on a par with conventional multiport laparoscopic surgery splenectomy (CMLS-SP).Aims:The aim of this systematic review and meta-analysis was to assess feasibility and safety of SILS-SP when compared with CMLS-SP.Materials and Methods:Eligible articles were identified by searching several databases including PubMed, EMBASE, CNKI (China) and the Cochrane Library, up until February 2016. Studies were reviewed independently and rated by Newcastle–Ottawa Quality Assessment Scale. Evaluated outcomes were complications, operative time, post-operative hospital stay, blood loss, starting diet, post-operative pain scores, conversion and analgesic requirements.Results:Ten retrospective studies met the eligibility criteria. Overall, there was no significant difference between SILS-SP and CMLS-SP in complications, operative time, post-operative hospital stay, blood loss, starting diet, post-operative pain scores, conversion and analgesic requirements.Conclusions:SILS-SP is feasible and safe in certain patients, with no obvious advantages over CMLS-SP. Therefore, it may be considered an alternative to CMLS-SP. We await high-quality, double-blind RCTs. These should include clear statements on standard scores of post-operative pain and cosmetic results, longer follow-up assessment and cost–benefit analysis.
