About Our Division

The prime focus of the Division of Colon & Rectal Surgery is the diagnosis and treatment of diseases and ailments arising in the anus, rectum, and large bowel (colon). All of the Division surgeons have completed fellowship training in this specialty and are board certified by the American Board of Surgery as well as the American Board of Colon and Rectal Surgery. Penn Colon and Rectal surgeons are highly experienced and committed to providing the entire spectrum of care for their patients. The Division sees patients with diverse problems, including colon, rectal, and anal cancer, inflammatory bowel disease (Crohn’s and ulcerative colitis), diverticular disease, problems with incontinence and prolapse, as well as hemorrhoids, fissures, and fistulas. The Division specializes in diagnosing colorectal conditions by colonoscopy, endorectal and endoanal ultrasound, flexible sigmoidoscopy, and routine proctoscopic examination. The Division treats appropriate cases operatively—specializing in sphincter (anal)-preserving colon and rectal surgery for cancer and benign disease, laparoscopic colon surgery, surgery for anal incontinence and rectal prolapse, and both operative and medical therapies for anal diseases and complaints. Penn Colon & Rectal Surgeons are recognized nationally and internationally for their clinical and scientific contributions.
