ABSTRACT
BACKGROUND AND AIM:
Acute severe lower gastrointestinal bleeding (LGIB) in patients with Crohn's disease (CD) is uncommon; however, it is a potentially life-threatening complication, and its recurrence is common. We thus aimed to identify the predictors for rebleeding in CD patients with acute severe LGIB and particularly focused on whether anti-tumor necrosis factor (TNF) therapy lowers the risk of rebleeding compared with conventional medical therapy (CMT) or surgery.METHODS:
The risk of rebleeding was analyzed in 131 CD patients with acute severe LGIB. Patients were classified into the CMT group (n = 99), anti-TNF therapy group (n = 22), and surgery group (n = 10). No patients in the surgery group received anti-TNF therapy.RESULTS:
During the median follow-up of 98 months after the first episode of acute severe LGIB, rebleeding occurred in 50.5%, 18.2%, and 30.0% of the CMT group, anti-TNF therapy group, and surgery group, respectively (P = 0.015). The cumulative risks of rebleeding at 1 and 10 years were 20.0% and 64.7% in the CMT group, 13.6% and 18.4% in the anti-TNF therapy group, and 0% and 40.7% in the surgery group, respectively (P = 0.020). Multivariable Cox regression analysis showed that anti-TNF therapy was associated with a lower risk of rebleeding compared with CMT (hazard ratio, 0.303; 95% confidence interval, 0.108-0.849; P = 0.023).CONCLUSIONS:
In CD patients with acute severe LGIB, anti-TNF therapy may reduce the risk of rebleeding compared with CMT. Although surgery is considered effective in preventing early rebleeding, concomitant anti-TNF therapy may be helpful in further lowering the long-term risk of rebleeding.Palavras-chave
