Laparoendoscopic single-site adrenalectomy versus multi-port laparoendoscopic adrenalectomy: A systemic review and meta-analysis.

ABSTRACT:

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.
