Abstract
A 73-year-old man developed abdominal pain after straining his abdomen due to constipation. He had undergone repair of an abdominal incisional hernia using a composite mesh in another hospital at the age of 67 years. He visited our hospital after 2 days because his abdominal pain persisted. Abdominal CT showed gas and an irregularly deformed mesh in the abdominal wall. A diagnosis of mesh infection due to intestinal penetration was made, and an emergency operation was performed. The composite mesh had been placed in the abdominal cavity, and folding of the mesh margin toward the abdominal cavity was observed. The mesh had adhered to, and had penetrated, the cecum. The mesh was removed, and the penetrated area was closed with sutures. For abdominal incisional hernias, repair using a composite mesh is widely performed. When the polypropylene mesh layer is exposed to the abdominal cavity, there is a risk of its strong adhesion to the intestinal tract, causing intestinal obstruction and enterocutaneous fistula. Therefore, mesh fixation at the abdominal wall requires careful attention.
