Colorectal Surgery

Colorectal surgery is performed to repair damage to the colon, rectum and anus, caused by diseases of the lower digestive track, such as cancer, diverticulitis, and inflammatory bowel disease (ulcerative colitis and Crohn’s disease).  Injury, obstruction, and ischemima (compromised blood supply) may require bowel surgery. Masses and scar tissue can grow within the rectum, causing blockages that prevent normal elimination of feces. Other diseases such as diverticulitis and ulcerative colitis can cause perforations in the rectum. Surgical removal of the damaged area or areas can return normal bowel function.

Common Procedures

Colorectal surgery procedures include:
  • Hemorrhoidectomies
  • Fistulotomy
  • Pilonidal cyst excision
  • Colon resection
  • Creation of colostomies, ileostomy



Diagnostic procedures, such as colonoscopy, are very important in colorectal surgery. A colonoscopy can tell what type of diagnosis should be given and what procedure is recommended to correct the condition.


Colorectal surgery is a necessary treatment option for colorectal cancer, ulcerative colitis, colectomy, Crohn's disease, and some cases of diverticulitis, often resulting in major reconstruction of the intestinal tract. Other bowel conditions that may require surgery to a lesser extent are hemorrhoids (internal or external), anal fistulas (an infected tunnel between the skin and the anus), rectal prolapse, pilonidal cyst excision and bowel incontinence. Most of these surgeries repair tears, remove blockages, or tighten sphincter muscles.


Some procedures, such as colon resection and creation of colostomy or ileostomy, are able to be done laproscopically. Laparoscopic surgery typically has lower risks, decreased recovery time, and smaller, more precise incisions.

Surgeon Brings Colorectal Surgical Robotics Expertise

Dr Feo on Minimally Invasive Surgery

"Minimally invasive procedures allow for less pain and quicker recovery. During da Vinci procedures I am 100% in control of the robotic-assisted da Vinci System, which translates my hand motions into smaller, more precise movements of the tiny instruments inside the patient's body. CMC was the first in NH to employ robotic fluorescence imaging technology (Firefly) to optimize and enhance robotic surgery techniques."
