Previous research has shown that the repair of a recurrent inguinal hernia is subject to a greater risk of additional recurrence. Further, bilateral inguinal hernia is subject to a greater recurrence risk than unilateral inguinal hernia. These increased risks may be due to certain anatomical difficulties that complicate the surgical approach in these types of patients. Some clinicians have suggested that laparoscopic approaches are better suited to recurrent and bilateral hernias, and in we delineate separate comparisons for primary, bilateral, and recurrent hernia.
Based on prospective data of the Swiss association of laparoscopic and thoracoscopic surgery, all patients undergoing unilateral TEP or TAPP between 1995 and 2006 were included. The following outcomes were compared: conversion rates, intraoperative and postoperative complications, duration of operation.Data on 4,552 patients undergoing TEP (n=3,457) and TAPP (n=1,095) were collected prospectively. Average age and American Society of Anesthesiologists score were similar in the two groups.
