The fate of the forgotten rectal pouch after Hartmann's procedure without reconstruction

The rectal pouches of 45 patients who underwent Hartmann's procedure and were not scheduled to have a colostomy closure were examined with an endoscope at least 1 year after operation. Twenty-five patients had no symptoms related to the rectal pouch. The rest had pain, mucous discharge, moderate-to-severe bleeding, or discharge of small bowel contents. Endoscopic findings included moderate-to-severe proctitis in 20 patients, 10 of whom had no symptoms. Polyps were found in four patients (two asymptomatic) and carcinoma in seven (one asymptomatic). Of 24 patients operated upon for diverticulitis, 12 had proctitis and 2 had polyps. Of 14 patients with carcinoma, 4 had proctitis, 1 polyps, and 5 carcinoma. Of two patients with benign polyps, one had polyps and one, carcinoma and of five patients with inflammatory bowel disease, four had proctitis and one, carcinoma. The treatment of polyps and carcinoma is the same as for other patients with these conditions. Proctitis should be treated with reanastomosis. The frequent presence of abnormality in the rectal pouch indicates the need for regular follow-up examinations of these patients.
