Open mesh repair of interstitial hernia containing small bowel

Abstract

Interparietal hernias are rare entities of the anterior abdominal wall in which the hernia sac protrudes between peritoneum, fascia, muscle, or subcutaneous tissue. There are three types of interparietal hernias: interstitial, superficial, and preperitoneal. The interstitial type hernia is rare and involves herniation between the abdominal wall musculature and fascial planes. Diagnosis is rarely made preoperatively, and treatment consists of operative reduction of the hernia sac with primary tissue or mesh repair. Repair of interparietal hernias can be performed open or laparoscopically. We report the case of a 40-year-old male who presented with an incarcerated interstitial hernia which contained small bowel and had developed after open appendectomy performed 20 years prior. The hernia was repaired using the open technique and employed a mesh for reinforcement. The patient tolerated the procedure well and remained free of recurrence.
