Sphincter Sparing Rectal Surgery

Overview

Sphincter sparing rectal surgery is a complex procedure that requires special training and immense precision to safely remove rectal tumors close to the anal sphincter. This procedure is typically performed on patients affected by rectal cancer.

Traditional surgical techniques may necessitate an ostomy, an opening within the abdominal wall that allows patients to have bowel movements. With the sphincter sparing procedure, however, the sphincter mechanism is kept intact, effectively eliminating the need for an ostomy. Following the procedure, patients will have the ability to use the restroom as they normally would, without the use of a permanent colostomy bag.  

Sphincter Sparing Rectal Surgery Options

There are various sphincter sparing rectal surgery techniques that aid the safe removal of rectal tumors without impacting sphincter function. Your surgeon at West Valley Colon and Rectal Surgery Center will educate you on the most appropriate treatment options.

Neoadjuvant Therapy

Neoadjuvant therapy is the administration of therapeutic agents for cancer, also known as chemotherapy, radiation, or hormone therapy. In regards to sphincter sparing rectal surgery, the goal of neoadjuvant treatment is to mitigate the rectal tumor before surgery to increase post-procedural success. 

Transanal Excision

Transanal excision is generally reserved for patients with early-stage rectal cancers. During the procedure, a surgeon removes the rectal tumor through the anus instead of the abdomen. There are many advantages to transanal excision, including minimal impact on sphincter function, a relatively quick recovery, and low perioperative morbidity.

Ileal Pouch-Anal Anastomosis (IPAA)

An ileal pouch-anal anastomosis (IPAA) is a surgical operation that removes the inflammatory, infectious, or cancerous colon and rectum to restore gastrointestinal function. Once the diseased colon and rectum is removed, an internal pouch is created and attached to the remaining anus to increase storage capacity while preserving continence.
