A new technique of "Marlex-peritoneal sandwich" in the repair of large incisional hernias.

Repair of a large abdominal wall incisional hernia is a difficult surgical problem with recurrence being a common complication. In addition, other complications such as hematomas, seromas, and sinus formation result from the use of foreign material. A new technique to obviate these complications was used in 60 patients with large incisional hernias repaired over the last 15 years. Marlex polypropylene mesh was used for repair, sandwiched between 2 layers of peritoneum of the overstretched hernia sac. There was no operative mortality and no recurrence in follow up from 3 years to 7 years. Postoperative complications encountered could be managed conservatively, without necessitating any major surgical procedure or mesh removal.
