Surgery for inflammatory bowel disease

Inflammatory bowel disease (IBD), primarily comprising Crohn’s disease and ulcerative colitis, involves chronic inflammation of the digestive tract. Consultant general and colorectal surgeon Mr Henry Ferguson provides expert surgical intervention to manage these complex conditions when medical treatments no longer suffice.

Surgery becomes necessary when symptoms are no longer controlled by drugs or when complications like blockages or perforations occur. This article explores surgery for inflammatory bowel disease in expert depth.

What is surgery for inflammatory bowel disease?

Surgery for inflammatory bowel disease involves the physical removal of damaged sections of the intestine or the creation of new pathways for waste to leave the body. It's a vital intervention for 20 to 30 per cent of ulcerative colitis patients and up to 75 per cent of those with Crohn's disease who eventually require surgical management.

For patients with ulcerative colitis, surgery can be curative if the entire large intestine (colon) is removed. In contrast, surgery for Crohn’s disease focuses on conserving as much of the bowel as possible, as the condition can recur in other parts of the digestive tract.

Data indicates that surgical intervention often significantly improves the quality of life for patients who have suffered from chronic pain, malnutrition, or medication side effects for many years.

When is surgery necessary for IBD?

Surgery is required when medical therapies don’t clear things up, or when emergency complications arise that threaten the patient's immediate health. Doctors typically recommend a surgical consultation if a patient develops a bowel obstruction, a fistula, or precancerous changes in the intestinal lining.

In emergency settings, surgery is vital for treating life threatening conditions such as a perforated bowel. Elective surgery is often discussed when a patient's quality of life is severely diminished despite using advanced biological therapies.

What are the different types of surgery?

The type of surgery depends entirely on whether the patient has Crohn’s disease or ulcerative colitis and the specific location of the inflammation. Modern techniques, such as laparoscopic (keyhole) surgery, have reduced recovery times and improved outcomes.

• Proctocolectomy: The complete removal of the colon and rectum, often resulting in a permanent or temporary ileostomy.
• IPAA (J-pouch): A procedure for ulcerative colitis where an internal pouch is created from the small intestine to replace the rectum, allowing for natural bowel movements.
• Resection: The removal of a specific diseased segment of the small or large intestine, after which the healthy ends are joined back together (anastomosis).
• Stricturoplasty: A bowel-sparing technique used in Crohn’s disease to widen a narrowed section of the intestine without removing any tissue.

How does surgery impact a patient's lifestyle?

Surgery often provides a dramatic reduction in symptoms, allowing many patients to return to work, travel, and exercise without the constant need for nearby facilities. While some procedures involve an ostomy bag, modern stoma care and support groups help patients adapt quickly to this change.

Research indicates that approximately 80 per cent of patients who undergo surgery for Crohn's disease report a significant improvement in their wellbeing five years post-operation. The goal of surgery isn’t just to treat the disease, but to restore a sense of normalcy to the patient's daily life.
