By Dr Pranab Gyawali, Consultant Gastroenterologist (UK-trained) in Dubai
Occasionally in clinic, I come across a piece of research that genuinely makes me pause and rethink how we understand ulcerative colitis. This is one of those.
As a UK-trained gastroenterologist in Dubai, practising in a JCI-accredited clinic, I find this type of research particularly interesting because it focuses not just on treatment, but on the underlying biology of the disease.
This video explores a very unusual question: could the appendix play a role in ulcerative colitis, and could removing it influence inflammation?

What does the appendix actually do?
The appendix is not a useless organ. It contains immune tissue and acts as a reservoir for beneficial gut bacteria. This allows it to play a role in regulating the gut microbiome and supporting immune balance.
This is important because ulcerative colitis is strongly linked to both immune system dysfunction and microbiome changes.
Why is the appendix relevant in ulcerative colitis?
Ulcerative colitis is not just inflammation of the colon. It is driven by complex interactions between the immune system and the gut microbiome.
The appendix sits at the centre of this interaction. Some research suggests it may act as a local driver or trigger point for inflammation in certain patients.
Can removing the appendix improve ulcerative colitis?
Some studies have explored whether removing the appendix could influence disease outcomes, particularly in patients whose ulcerative colitis is not fully controlled.
There is some evidence of improved remission rates in selected groups, but this is not consistent across all patients and remains an area of ongoing research.
Is appendix removal a standard treatment?
No. Appendectomy is not part of standard treatment guidelines for ulcerative colitis.
Most patients are treated with advanced medical therapies such as biologics and JAK inhibitors.
How is this different from Crohn’s disease?
Crohn’s disease behaves very differently. It is more widespread and can affect the entire gastrointestinal tract.
Appendectomy does not improve Crohn’s disease and may be associated with a higher likelihood of diagnosis, likely because early Crohn’s can mimic appendicitis.
This highlights a key difference in disease biology between ulcerative colitis and Crohn’s disease.
What does this mean for patients?
The key message is not that surgery is the answer.
The key message is that we are beginning to understand ulcerative colitis at a deeper biological level, particularly the role of the immune system and microbiome.
The future of treatment is not removing organs, but targeting these pathways more precisely.
