This study assessed safety and efficacy associated with hernia prophylaxis using a retromuscular slowly resorbable synthetic mesh for stoma reinforcement.
This was a cohort study with a historic reference group. The study took place in a high-volume surgical department. During a 2-year period (July 2012–July 2014), we included 109 patients undergoing emergency surgery with formation of ileostomy or colostomy. All patients received a retromuscular slowly resorbable synthetic mesh (TIGR®, Novus Scientific) at the stoma site. The reference group included 117 patients who underwent emergency stoma formation without a prophylactic mesh in the 2-year period prior to July 2012. The primary endpoint was effect on prevention of parastomal hernia within 1 year. Secondary endpoints were 30-day and 1-year complications including mortality.
The operative field was contaminated or dirty in 48% of the procedures. Operative time was significantly longer in the mesh group. The cumulative incidences of parastomal hernia at 1 year for the control and the mesh group were 8 and 7% (p = 0.424), respectively. The postoperative 30-day and 1-year rate of complications, reoperations and mortality were not different between the two groups. No patients underwent removal of the mesh and no clinical mesh infections were seen.
Use of a resorbable synthetic mesh during emergency ostomy formation showed no significant preventive effect on formation of parastomal hernia after 1 year. Although surgery was often conducted in a severely contaminated field, the procedure was without significantly increased complication rate.
