A prospective study between two different techniques for the repair of a large recurrent ventral hernia: a double...

Massive ventral hernias are difficult to repair, especially with multiple recurrences. Numerous methods of repair have been described with an overall recurrence rate up to 33% after first repair and 44% after second repair, mostly occurring within 3 years of the repair.

This is a prospective study on 41 patients who underwent surgery between January 2000 and August 2004 for recurrent large ventral hernias. Patients were randomized into two groups: group A included 22 patients, who were subjected to suture repair with an onlay polypropylene mesh, and group B, which included 19 patients, who were subjected to a tailored double mesh (Vicryl + polypropylene) intraperitoneal repair.

Superficial wound infection occurred in two patients (4.8%), one in each group. By a median follow up of 30 months, seroma formation or hernia recurrence was not found in group B in comparison to seven and six cases, respectively, in group A (p < or = 0.000). There was no intraabdominal complication in the cases subjected to double mesh intraperitoneal repair due to the protective effect of the inner Vicryl layer, which is characterized by its low reactivity.

A double mesh intraperitoneal repair (ADMIR) is successful for the repair of recurrent large ventral hernias as it is applicable to all sites of ventral hernias. The mesh is mostly hidden within the abdomen with relatively affordable pain allowing for early mobilization, the complication rate is low and so far no recurrence was reported. A long-term follow up with a larger number of cases is advisable in order to determine the long-term success of this kind of repair.
