Parastomal hernias occur frequently after placement of a permanent colostomy. Preliminary reports have shown a beneficial effect of placing a mesh at the primary operation to prevent the formation of a parastomal hernia. We studied the safety and prophylactic effect of placing a newly designed polypropylene mesh in an onlay position at the primary operation.
Methods
This was a prospective study that included 25 patients scheduled for elective colorectal surgery. Risk factors for development of parastomal hernia were recorded before surgery. A prepared lasercut polypropylene mesh with six “arms” was placed in an onlay position. Immediate and long-term complications were evaluated by an experienced stoma nurse and a surgeon. Abdominal ultrasound was performed at 6 and 12 months follow-up. Parastomal hernia was defined as both clinical and ultrasonographic signs of protrusion in the vicinity of the stoma.
Results
The median follow-up time was 12 (range, 2–26) months. One patient died eight days after surgery. Of the 24 patients included, none had infections or immediate complications after surgery. Two patients had minor complications necessitating a local revision of one of the mesh arms. No other long-term complication was found. Two patients had signs of parastomal hernia at 6 and 12 months follow-up, respectively.
Conclusions
Placement of a polypropylene mesh in an onlay position at the primary operation is a safe procedure and probably results in a low risk of parastomal hernia occurrence.
