Colectomy for acute colitis: is it safe to close the rectal stump?

ABSTRACT

We report 62 operations for acute colonic inflammatory bowel disease in which the rectal stump was closed. Operative findings were of severe colitis in 46, toxic megacolon in 8 and faecal peritonitis in 8 patients. Histology showed ulcerative colitis in 48, Crohn's disease in 9 and indeterminate colitis in 5 patients. Clinical evidence of stump leakage occurred in only one of 53 patients with a long rectal stump in contrast to 3 of 9 patients who had a short rectal stump. Leaving a very short stump also led to difficulty at subsequent proctectomy in 3 patients and at restorative proctocolectomy in 1 patient. This suggests that careful closure of the rectum above the peritoneal reflection can be a safe means of dealing with the rectal stump after total colectomy and ileostomy for acute colitis.
