The Section of Colon and Rectal Surgery in the Division of General Surgery at Washington University School of Medicine provides comprehensive care for patients with diseases of the colon, rectum and anus.

Washington University colorectal surgeons have special expertise in laparoscopic colon surgery, offering this treatment for colon and rectal cancer, diverticulitis, ulcerative colitis, Crohn’s disease, colon polyps, rectal prolapse and chronic constipation.

Working as part of a leading academic medical center, an integrated team of colon and rectal surgeons, gastroenterologists, oncologists and radiologists works together to provide the best possible care for patients in the St. Louis region and beyond.
