[Use of polypropylene mesh for incisional hernia repair]

Incisional hernia is an important complication of abdominal surgery. Procedures for the repair of these hernias with sutures and with mesh have been reported, but there is no consensus about which type of procedure is best. We have performed a retrospective analysis on 1014 patients operated on in our unit between 1994 and 2003 for simple or recurrent incisional hernias. The polypropylene mesh has been used in a number of 107 patients. The mesh has been placed either intraperitoneal, extraperitoneal/subfascial or onlay. Median follow-up was 36 months. There were 1 enterocutaneous fistula and 5 wound sinus developed. The mesh had to be removed in 6 cases. All of these complication developed when the mesh has been placed either extraperitoneal/subfascial or onlay. We note 5 recurrent incisional hernias after a period of up to 24 months. The recurrence rates after open mesh repair are less then after primary closure. The intraperitoneal use of polypropylene mesh with omental coverage is a good procedure with less complications.
