Colectomy – Bowel Resection Surgery

What is a Colectomy?

Colectomy is a surgical procedure to remove all or part of the colon (also known as the large intestine). It is commonly performed to treat colon cancer, inflammatory bowel disease (IBD) like Crohn’s disease or ulcerative colitis, diverticulitis, or colon blockages.

Depending on the condition, the procedure may involve:
  • Partial Colectomy (Segmental Colectomy) – Only the affected portion of the colon is removed
  • Total Colectomy – The entire colon is removed
  • Hemicolectomy – Right or left side of the colon is removed
  • Proctocolectomy – Removal of the colon and rectum
Why is a Colectomy Performed?

A colectomy may be recommended for:

  • Colon cancer or polyps
  • Diverticulitis with complications
  • Inflammatory bowel disease (IBD) – Crohn’s or ulcerative colitis
  • Bowel obstruction or perforation
  • Bleeding or ischemia in the colon
  • Precancerous lesions or genetic conditions (like FAP or Lynch syndrome)
Types of Colectomy Techniques
  1. Open Colectomy

    2. – Traditional surgery with one large abdominal incision

  2. Laparoscopic Colectomy

    3. – Minimally invasive surgery using small incisions and a camera

  3. Robotic-Assisted Colectomy

    4. – Offers enhanced precision and quicker recovery using robotic tools

What to Expect During Surgery
  • Performed under general anesthesia
  • Duration: Typically 2–4 hours
  • The affected part of the colon is removed, and the healthy ends are joined (anastomosis)
  • In some cases, a temporary or permanent stoma (colostomy/ileostomy) may be created
Recovery after Colectomy
  • Hospital stay: 3–7 days depending on surgery type
  • Full recovery: 4–6 weeks
  • Gradual reintroduction of diet
  • Hydration and bowel management guidance
  • Stoma care support (if applicable)
  • Regular follow-ups to monitor healing and function
Risks and Complications
  • Bleeding or infection
  • Anastomotic leak (at the reconnection site)
  • Bowel obstruction or adhesions
  • Stoma-related issues
  • Changes in bowel habits
Life after Colectomy

Many patients return to normal activities with lifestyle adjustments. Bowel movement frequency and consistency may change, but long-term quality of life is generally good. If a stoma is needed, stoma care nurses provide education and support.
