Colon and Rectal Surgery

About Us

Weill Cornell Medicine’s colorectal surgeons are nationally and internationally recognized for their pioneering efforts and extensive experience in minimally invasive surgery and state-of-the-art laparoscopic technologies for colorectal cancer, Crohn’s disease and other inflammatory diseases.

The Colon and Rectal Division of the Department of surgery specializes in treating the full range of diseases and disorders that affect the colon, rectum, anus, appendix and small bowel. 

In particular, we concentrate on precancerous polyps and cancers of the colon, rectum, anus and appendix as well as inflammatory bowel disease diverticulitis, lower gastrointestinal bleeding, ischemic or inflammatory colitis, familial adenomatous polyposis, rectal prolapse, pelvic floor disorders, constipation, incontinence, hemorrhoids, anal fissures and pilonidal cysts. 

Weill Cornell Medicine's dedication to improving the lives of patients with colon and rectal disorders extends to a robust research program, where we are developing new types of minimally invasive devices and procedures, improving postoperative recovery and maintaining our commitment to excellence in patient care.

Through our medical education programs in New York, we also train future generations of colorectal surgeons.
