Short-middle Term Results of the ONSTEP Technique for Repair of Inguinal Hernia

Abstract

The open new simplified totally extraperitoneal (ONSTEP) technique is a technique for the repair of inguinal hernia through the anterior approach. This technique places the mesh in the preperitoneal space medially and between the internal and external oblique abdominis muscles laterally. It has been performed in our country as a novel technique since November 2016. We have also introduced the technique as a day-surgery since 2017 and experienced a total of 367 lesions in 345 patients for two years. Recurrence occurred in only one case (0.27%). Complications included subcutaneous hemorrhage in eight cases, hematoma in three, seroma in four, surgical wound infection in two, and mesh infection in one. No serious complications such as postoperative intestinal obstruction, chronic pain and bladder injury were encountered. The mean operating time was 26 ± 7 min. Since the ONSTEP technique does not require any technique for dissecting the lateral preperitoneal space, it shortens the operating time compared with other transinguinal preperitoneal repairs (TIPP). From these findings, the ONSTEP technique appears to be a simple and highly safe technique that can be used as a day-surgery. We should wait accumulation of clinical experiences as to the long-term results, but we have gained favorable short-middle term results.
