Over the past 20 years, TP use has doubled, whereas intestinal surgery has fallen by one-third among the UK population of Crohn's patients. Prolonged exposure is associated with a reduced likelihood of surgery whereby more than 12 months TP therapy reduces the risk of first intestinal surgery two-fold; however, early initiation of TP treatment offered no apparent additional benefit.

TP use is associated with a 40% lowered risk of surgical resection in patients with CD. Despite significant reductions in rates of surgical resection in patients with CD over the last 5 decades and increasing use of TPs, a large proportion of patients with CD still require resectional surgery.

SUMMARY BackgroundDiagnostic imaging plays a pivotal role in the diagnosis and management of inflammatory bowel disease (IBD); however, increasing use has led to concerns about the malignant potential of ionising radiation. Several studies have demonstrated that diagnostic imaging can result in exposure to potentially harmful levels of ionising radiation in IBD patients.

SUMMARY BackgroundThe role of thiopurines in altering the risk of colectomy in ulcerative colitis (UC) remains unclear.
