Background: To investigate the outcomes of laparoendoscopic single-site adrenalectomy (LESS-A) compared to multi-port laparoendoscopic adrenalectomy (m-LA).
Methods: Studies comparing LESS-A with m-LA were identified from PubMed, Embase, and Cochrane Library before June 2020. Post-operative pain, resumption outcomes, and perioperative outcomes were analyzed. We conducted meta-analyses using the Mantel-Haenszel method with random-effects model. Subset analyses were conducted according to peritoneal and retroperitoneal approaches. A small study effect was illustrated using funnel plots and Egger's test.
Results: One randomized controlled trial (RCT) and nineteen retrospective cohort studies involving 1554 patients were included for analyzed. Pooled analysis showed that LESS-A had significantly lower postoperative pain scores (MD -0.77, 95%CI -1.45 to -0.10) and less pain medication used (RR 0.74, 95%CI 0.60 to 0.91) compared to m-LA. Besides, LESS-A had significantly shorter hospital stays (MD -0.75, 95%CI -1.18 to -0.33), shorter duration of oral intake resumption (MD -0.33, 95%CI -0.60 to -0.06), and better cosmetic satisfaction (SMD 1.15, 95%CI 0.21 to -2.09). As for perioperative outcomes, LESS-A led to significant longer operative time (MD 13.43, 95%CI 4.08 to 22.77). No significant differences were observed in terms of the remaining perioperative outcomes.
Conclusions: LESS-A is associated with less post-operative pain and quicker recovery duration. However, the longer operative time of LESS-A compared with m-LA is a drawback.
