Laparoscopic versus open mesh repair for recurrent inguinal hernia: a meta-analysis of outcomes.

Background: The objective of this study was to examine the outcomes of comparisons between laparoscopic and open mesh repairs in the setting of recurrent inguinal hernia.

Methods: The electronic databases MEDLINE, Embase, Pubmed, and the Cochrane Library were used to search for articles from 1990 to 2008. The present meta-analysis pooled the effects of outcomes of a total of 1,542 patients enrolled into 5 randomized controlled trials and 7 comparative studies, using classic and modern meta-analytic methods.

Results: Significantly fewer cases of hematoma/seroma formation were observed in the laparoscopic group in comparison with the Lichtenstein group (odds ratio, .38; .15-.96; P = .04). A matter of great importance is the higher relative risk of overall recurrence in the transabdominal preperitoneal group compared with the totally extraperitoneal group (relative risk, 3.25; 1.32-7.9; P = .01).

Conclusions: Laparoscopic versus open mesh repair for recurrent inguinal hernia was equivalent in most of the analyzed outcomes.
