Dr Green's specialized colon and rectal training brings to the area an expertise in the diagnosis, medical management and surgical treatment of:

• Colorectal and anal tumors, including hereditary tumor syndromes such as Familial Polyposis, and hereditary non-polyposis colon cancers. (New surgery techniques for rectal cancers may preserve the anal sphincters, often avoiding the need for a colostomy.)

• Inflammatory bowel disease (Crohn's Disease and Ulcerative Colitis), including ileo-anal pouch procedures, also called J- or S- pouches.

• Diverticular disease, especially when complicated by fistulas to other organs such as the bladder, uterus or vagina.

• Endoscopy of the colon and rectum: Flexible and rigid evaluations of the anus, rectum, and colon (with biopsy or polyp removal if necessary).

• Intestinal and anorectal functional disorders such as anal incontinence (the accidental passage of stool or gas), anal or rectal pain, chronic diarrhea and rectal prolapse (falling out).

• Common anorectal conditions such as hemorrhoids, fissures, abscesses, and fistulas.
