Mesh erosion into the colon following repair of parastomal hernia: A case report

BACKGROUND: In recent years, mesh has become a standard repair method for parastomal hernia surgery due to its low recurrence rate and low postoperative pain. However, using mesh to repair parastomal hernias also carries potential dangers. One of these dangers is mesh erosion, a rare but serious complication following hernia surgery, particularly parastomal hernia surgery, and has attracted the attention of surgeons in recent years. CASE SUMMARY: Herein, we report the case of a 67-year-old woman with mesh erosion after parastomal hernia surgery. The patient, who underwent parastomal hernia repair surgery 3 years prior, presented to the surgery clinic with a complaint of chronic abdominal pain upon resuming defecation through the anus. Three months later, a portion of the mesh was excreted from the patient’s anus and was removed by a doctor. Imaging revealed that the patient’s colon had formed a t-branch tube structure, which was formed by the mesh erosion. The surgery reconstructed the structure of the colon and eliminated potential bowel perforation. CONCLUSION: Surgeons should consider mesh erosion since it has an insidious development and is difficult to diagnose at the early stage.
