Introduction of the Mini- or Less-open Sublay Operation for Abdominal Wall Hernia

Abstract

Objective : To report short-term results of the recently introduced mini- or less-open sublay operation (MILOS) technique for abdominal wall hernia.

Method : We analyzed the surgical results of six cases in which MILOS repair was performed for abdominal wall hernias with less than 5-cm protrusion through the hernia orifice. Further, the results were compared with 39 cases where the laparoscopic intraperitoneal onlay mesh (IPOM)-Plus technique was used.

Results : There were no intraoperative complications in patients in the MILOS repair group. The average operation time was 133.3 minutes for MILOS repair and 123.4 minutes for the laparoscopic IPOM-Plus technique, the difference not being statistically significant (P = 0.545). Post-operative pain on the day after surgery and 7 days after surgery was significantly lesser with MILOS repair (P = 0.019 and 0.031, respectively).

Conclusion : MILOS repair for abdominal wall hernia can be performed safely even during the introduction period of surgical procedure without extending the duration of the operation, and the postoperative pain is less than that of the laparoscopic IPOM method.
