A case of a stuck mesh in the rectum after pelvic surgery

A 67‐year‐old woman was referred to our hospital for further evaluation of a positive fecal occult blood test. Colonoscopy revealed an elevated rectal lesion (10 mm in size) with a central depression. A rod‐like object was noted in the center of the lesion. Magnifying endoscopy with narrow‐band imaging showed obscure surface structures and dilated vessels. Magnifying endoscopy with crystal violet staining showed that the pit pattern had disappeared. These endoscopic findings suggested that the lesion was comprised of granulation tissue. A detailed medical history revealed that she had undergone a total hysterectomy with mesh placement for bladder prolapse. We reasoned that the mesh used during pelvic surgery might have penetrated the rectum. She underwent subsequent surgery to remove the mesh. Although most foreign bodies in the rectum are swallowed or self‐inserted, pelvic surgery is another source of foreign bodies in the rectum.
