Inflammatory bowel disease (IBD) is a group of conditions that cause ongoing inflammation in the digestive tract, with Crohn’s disease and ulcerative colitis being the two main types. Although they share some features, they affect the digestive tract differently.
For many people with IBD, treatment centres on medication rather than surgery. However, surgery may become part of the treatment pathway when the disease remains difficult to control or complications develop, significantly affecting daily life.
Medical treatment is generally used to control inflammation, manage symptoms and maintain remission. Surgery is therefore not automatically required simply because someone has been diagnosed with IBD.
A healthcare team may begin discussing surgery when medical treatment does not adequately control the disease or when complications cannot be managed safely with medication alone. Whether surgery is suitable also depends on how the disease is affecting the bowel and the patient’s response to treatment.
Surgery may also need to be considered more urgently when serious complications develop. For this reason, surgical treatment can range from a planned procedure after careful discussion to emergency surgery in more severe circumstances.
Crohn’s disease can affect different areas of the digestive tract and may involve the full thickness of the bowel wall. Over time, ongoing inflammation can lead to complications such as intestinal strictures, fistulas or abscesses.
Surgery may be considered when Crohn’s disease leads to:
In some cases, a diseased section of the intestine may be removed and the healthy ends reconnected.
Unlike Crohn’s disease, ulcerative colitis affects the colon and rectum. Surgery may be discussed when symptoms continue to have a substantial effect on daily life despite medical treatment or when severe complications occur.
For example, surgery may become an option when frequent or severe flare-ups do not respond adequately to medication. Emergency surgery may also be required if severe inflammation cannot be controlled or complications such as toxic megacolon, significant bleeding or colon perforation develop.
Surgery for ulcerative colitis may involve removing the colon and, depending on the procedure, the rectum. Options for passing stool after surgery can include an ileostomy or an ileoanal pouch, commonly known as a J-pouch.
The role of surgery differs because the two conditions behave differently.
With Crohn’s disease, surgery generally aims to address a specific area of diseased bowel or a complication while preserving as much healthy bowel as possible. Because Crohn’s disease can occur in other parts of the digestive tract, further disease activity remains possible after surgery.
With ulcerative colitis, the disease is limited to the colon and rectum. Removing the colon and rectum therefore removes the areas affected by ulcerative colitis.
If surgery has been raised as a possibility for your IBD, you may have questions about why it is being considered and what it could mean for your treatment. A surgical consultation can help you understand the reason for considering an operation and how it may fit alongside your ongoing IBD care.
At Kam Colorectal Centre, patients can consult Senior Consultant Colorectal Surgeon Dr Kam Ming Hian, for assessment and treatment planning. With more than two decades of clinical experience, Dr Kam diagnoses and manages a wide range of conditions affecting the colon and rectum.

Recovery after IBD surgery can take several weeks, depending on the procedure and the patient’s overall health. Many patients gradually return to everyday activities over 4–6 weeks, although recovery after more extensive or emergency surgery may take longer.
Not necessarily. Many people with IBD are managed with medication and ongoing monitoring. Whether surgery becomes appropriate depends on factors such as the type of IBD, disease severity, response to treatment and whether complications develop.
Many patients can gradually return to work, exercise, travel and other everyday activities after recovering from IBD surgery. Depending on the operation, some may need longer-term adjustments to their diet or bowel habits, particularly if a stoma or ileoanal pouch is involved.
Not every IBD operation requires a stoma. A temporary stoma may be created to allow the bowel to heal after certain procedures, while a permanent stoma may be necessary if the rectum and anus are removed or the bowel cannot be safely reconnected.
Before IBD surgery, you may undergo blood tests and other assessments to check your general health and nutritional status. Your care team may also review your medications, advise when to stop eating and drinking before surgery and provide bowel preparation instructions if needed.
