Popis: Single incision laparoscopic appendectomy (SILA) has been proposed as an alternative to conventional laparoscopic appendectomy (CLA). The aim of this study was to evaluate the safety and efficacy of SILA when compared with CLA through a systematic review. We performed an electronic search of EMBASE, PubMed, MEDLINE, and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) that compared SILA with CLA were included. Six RCTs met eligibility criteria, which included a total of 800 patients, 401 in the SILA group and 399 in the CLA group. There were no significant differences in terms of overall complications (odds ratio [OR] 0.93; 95 % confidence interval [CI] 0.59–1.47; p = 0.77). SILA had a higher technical failure rate (OR 3.30; 95 % CI 1.26–8.65; p = 0.01) and required a longer operative time (mean difference [MD] 4.67; 95 % CI 1.76–7.57; p = 0.002). SILA was associated with better cosmetic results (standardized MD –0.4; 95 % CI –0.64 to –0.16; p = 0.001) and earlier return to normal activity (MD –0.64; 95 % CI –1.09 to –0.20; p = 0.005), although these advantages should be taken with caution due to the small number of studies reporting these two items and the short follow-up in the evaluation of cosmetic results. There were no significant differences in terms of postoperative pain or length of hospital stay between groups. SILA is comparable to CLA in selected patients, although it is associated with a higher technical failure rate and longer operative time. Further randomized trials are needed to determine if SILA really offers benefits over CLA.
