The following link mentions a longitudinal study (20 years) conducted by a surgeon on Crohn's. The key findings of the study, mentioned in the link:
- Strictureplasty carries a lower risk of stricture recurrence than resection.
- If a patient has a stricture, but the stricture doesn't cause any symptoms, the patient might still want to consider a strictureplasty because eventually 25% of strictures will cause problems.
- However, if the stricture can only be removed via a resection, then the surgeon advises the patient wait, because there is still a 75% chance that the stricture will not cause "any harm."
