What is bowel bypass syndrome?
Bowel bypass syndrome (Cheng, 2012).
‘Bowel bypass syndrome is also known as bowel-associated dermatitis-arthritis syndrome and blind loop syndrome.
Bowel bypass syndrome is a relapsing condition characterised by rash and arthritis. It is most commonly associated with bowel shortening surgery, where a ‘blind loop’ of bowel is created. This kind of surgery was previously popular for the treatment of morbid obesity. Up to 20% of patients undergoing bowel bypass surgery develop bowel bypass syndrome.
A similar syndrome has been reported in people who have not had bowel bypass surgery (bowel bypass syndrome without bowel bypass). In these cases associated conditions have included:
- Inflammatory bowel disease.
- Peptic ulcer disease.
What are the symptoms of bowel bypass syndrome?
Onset of symptoms of bowel bypass syndrome is usually 1-6 years following bowel bypass surgery. Symptoms usually last 2-4 weeks and may recur every 4-6 weeks.
- Small red bumps (papules), blisters and pustules on trunk and upper arms.
- May resemble acute neutrophilic dermatosis (Sweet’s syndrome).
- Erythema nodosum.
- Muscle aches and pains.
- Non-destructive polyarthritis (affecting many joints).
- Tenosynovitis (inflammation of tendons).’
