Colorectal Surgery Q & A

Why might I need colorectal surgery?

You may need immediate surgery for an acute injury, rectal cancer, or colon cancer. However, for most colorectal conditions, your treatment begins with conservative therapies. Then, Dr. Harris consults with you about surgery when medical options fail to improve your symptoms.

These are a few examples of the colorectal conditions that often require surgery:

  • Colon cancer
  • Diverticulitis
  • Rectal cancer
  • Anal fissure
  • Motility disorders
  • Colorectal polyps
  • Endometriosis
  • Rectal prolapse
  • Bowel obstruction
  • Inflammatory bowel disease
  • Volvulus (twisted colon)

The type of surgery you need depends on your diagnosis and the severity of the disease.

What procedures might I receive during colorectal surgery?

Dr. Harris performs many surgical procedures. These are a few examples:

Colectomy and proctocolectomy

Colectomy refers to surgery to remove the damaged part of your colon, while a proctocolectomy is the same procedure for your rectum. After removing a small segment, Dr. Harris can reconnect the two ends to restore function.

In cases of severe disease, Dr. Harris must remove the entire colon. Then she performs a procedure such as a colostomy or ileal pouch anal anastomosis to create a path for eliminating waste.


Rectopexy is a surgical procedure to repair a rectal prolapse by securing the rectum in its normal position.

Will I have minimally invasive colorectal surgery?

Dr. Harris specializes in minimally invasive techniques to manage numerous colorectal conditions, including colon cancer, diverticulitis, polyps, motility disorders, rectal prolapse, and endometriosis.

During minimally invasive surgery, you either don’t need an incision or your procedure is performed through a few small incisions:

Colonoscopy and sigmoidoscopy

These procedures don’t need an incision because Dr. Harris inserts long, flexible scopes through the anus. Then, she gently advances the scope through your rectum or colon. A sigmoidoscopy is done for your rectum and lower colon, while a colonoscopy is performed for the entire length of the colon.

The scopes contain lights and a video camera that allow Dr. Harris to examine the inside of your rectum and colon. Then she inserts surgical instruments through the scope to repair the problem or remove tissues.


This procedure uses another type of scope inserted through a small incision in your abdomen. To perform your surgery, she may guide instruments through the scope or make another small incision to accommodate the tools.
