Transabdominal preperitoneal versus totally extraperitoneal repair of inguinal hernia: a meta-analysis of randomized studies

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.
