Chronic anemia due to transmural e-PTFE anti-adhesive barrier mesh migration in the small bowel after open incisional hernia repair: A case report

Introduction: Meshes are commonly employed in abdominal hernia repair to reduce recurrence rates. Prosthetic repair, however, increases the risk of mesh related complications, including migration into adjacent viscera and erosion which can occur as uncommon and can be difficult to be diagnose. Presentation of case: This is a case of transmural migration of composite mesh into the bowel, presenting as chronic abdominal pain and anemia 14 years after incisional hernia repair. Discussion: Mesh implantation in hernia repair has increased the incidence of complications, such as seroma, hematoma and infection. Migration into adjacent viscera and erosion may present as complications related to the use of meshes. Their precise frequency after abdominal wall hernia repair is not well known and their late occurrence can make the diagnosis difficult. Conclusion: Transmural migration of composite mesh is an uncommon complication of incisional hernia repair. Its pathogenesis is still not completely clear but it has been reported many years after implant surgery. It should be considered in a typical presentation of patients with history of previous prosthetic ventral hernia repair.
