Abstract
BACKGROUND: Previous meta-analyses on the clinical outcome after laparo-endoscopic single-site surgery (LESS) versus conventional laparoscopic surgery (CLS) have not revealed any major differences in postoperative pain between the two procedures. This meta-analysis aims to evaluate the difference in postoperative pain between the two procedures, focusing on whether LESS was conducted with a non-expanding port (LESSnonex) or a port expanding (LESSex) within the incision.
METHOD: EMBASE, Medline, PubMed, Science Citation Index Expanded, and Cochrane Central Register of Controlled Trials were searched for randomized clinical trials (RCTs) on LESS versus CLS for general abdominal procedures. Weighted mean difference (WMD) and Odds ratios (OR) were calculated with 95% confidence intervals (CI).
RESULTS: A total of 29 RCTs with 2999 procedures were included. Pain (VAS 0-10) 6 h after surgery was significantly lower in the group where LESS was conducted with LESSnonex compared to CLS, WMD=-0.72 (- 1.10 to - 0.33). Pain 18-24 h was significantly higher in the group where LESS was conducted with LESSex compared to CLS, WMD = 0.38 (0.01-0.75). Wound-related complications were significantly more frequent in LESSex procedures compared to CLS, OR = 1.94 (1.03-3.63).
CONCLUSION: The present meta-analysis indirectly indicates that the type of access device that is used for an abdominal LESS procedure may contribute to the development of early postoperative pain as the use of a non-expanding model was associated with a more advantageous outcome. Direct randomized comparison of LESSnonex and LESSex is warranted to confirm if the use of expanding access devices generates more pain and wound complications.
