Background:
The aim of the present study was to comparatively evaluate the outcomes of laparoscopic transabdominal preperitoneal inguinal hernia repair and totally extraperitoneal repair.
Methods:
The electronic databases of Medline, EMBASE, and the Cochrane Central Register of Controlled Trials were searched, and a meta-analysis of randomized clinical trials was undertaken.
Results:
Seven studies comprising 516 patients with 538 inguinal hernia defects were identified. A shorter recovery time (P = .02) was found for totally extraperitoneal repair in comparison with transabdominal preperitoneal inguinal hernia repair (weighted mean difference = -.29; 95% confidence interval [CI], -.71 to .07) although the length of hospitalization (P = .89) was similar in the 2 treatment arms (weighted mean difference = .01; 95% CI, -.13 to .15). Operative morbidity (P = .004) was higher for the preperitoneal approach (odds ratio = 2.15; 95% CI, 1.29 to 3.61). No differences were found with regard to the incidence of recurrence, long-term neuralgia, and operative time.
Conclusions:
Current evidence suggests similar operative results for endoscopic and laparoscopic inguinal hernia repair, with a trend toward higher morbidity for the preperitoneal approach. Randomized trials with a longer-term follow-up are needed in order to assess the effect of each approach on the prevention of recurrence.
