In Situ Mesh Repair of Parasternal Hernias

Abstract

Options for the repair of parastomal hernias include contralateral transposition or in situ repair. The latter can be accomplished either primarily or with prosthetic mesh. Concerns with mesh include possible gut erosion and infection. Recurrence rates in the literature are dismal regardless of technique. We retrospectively reviewed our experience with this problem focusing on in situ repairs. We identified 9 patients who underwent 10 in situ repairs. Of these, 6 were women, average age was 69.4 years, and stomas had been constructed for cancer in 6, inflammatory bowel disease in 2, and incontinence in 1. Eight patients had colostomies; one had an ileostomy. All patients were symptomatic from their hernias. Repairs were performed an average of 8 years after stoma construction. Hernia repair was performed transabdominally in four and through a parastomal incision in six. Complications included hematoma formation requiring evacuation in one and delayed resumption of oral intake secondary to nausea and cramps in three. Of the 9 initial repairs, 1 recurred (11%) and was repaired without subsequent failure. No mesh erosions or wound infections have occurred. This technique is safe and may be preferable to contralateral placement of the stoma.
