PURPOSE: Tension-free hernia repair with polypropylene mesh plug and patch is currently the most popular technique for open inguinal hernioplasty. It is well tolerated by most patients with few complications. Despite these excellent results, late-onset complications may occur. METHODS: An 83-year-old man reported 2 weeks of bloody stool. His medical history was significant for a left open inguinal herniorrhaphy with the mesh plug and patch technique. Barium enema revealed a stenotic segment in the sigmoid colon and multiple diverticulosis. Because a malignant lesion could not be ruled out, the patient underwent an operation. Laparotomy revealed an inflamed sigmoid colon with diverticulosis adherent to a hard tumor, which was mesh plug used for the previous open inguinal hernia repair. After mobilization of the adhesion between the mesh plug tumor and the sigmoid colon, sigmoidectomy was performed. The patient's postoperative course was uneventful. CONCLUSIONS: We reported a case of sigmoid colon diverticulosis adherent to mesh plug migration after open inguinal hernia repair. The potential risk of plug migration should be well understood by the surgeon. To avoid this risk completely, several methods have been proposed such as suturing the plug and patch together, or using an all-in-one design such as the Prolene Hernia System (Johnson and Johnson Co., Tokyo, Japan).
