Mesh migration to the sigmoid colon complicated by the formation of colocutaneous fistula 36 years post incisional hernia repair: a case report

This article provides clinical insights into a rare instance of mesh patch migration complicated by colocutaneous fistula formation occurring post incisional hernia repair operation in a 67-year-old male. Our patient had a history of laparotomy due to a gunshot wound, followed by the development of an incisional hernia which was subsequently repaired with mesh implantation. Further examinations suggested mesh migration to the sigmoid colon, necessitating him to undergo laparotomy. While some complications from mesh placement are well known, mesh migration to the sigmoid colon remains an extremely rare complication, particularly after such an extended period, and only reported in the literature in few cases with inguinal hernia. This case underscores the importance of considering mesh migration, although rare, as a potential diagnosis in patients with prior hernia repairs, regardless of the elapsed duration since surgery. It emphasizes the need for further research to establish follow-up guidelines for patients with mesh placement (refer to graphical abstract).
