Small-Bowel Angioectasias: Are They Responsible for a Real Impact on Survival?

This study aimed to evaluate the effect of small-bowel angioectasia on survival, given the hypothesis that angioectasia might be an independent risk factor of frailty and poor outcomes. In this retrospective cohort study, all patients undergoing small-bowel capsule endoscopy between 2010 and 2013 for obscure gastrointestinal bleeding from a Portuguese tertiary centre were included. Follow-up started after capsule endoscopy and ended upon death or end of the study (November 2020). Survival analysis was performed using a Cox proportional-hazards model, in order to analyse the effect of small-bowel angioectasia on survival as well as potentially confounding factors (age, vascular diseases and chronic kidney disease). A total of 176 patients were included in this study (50.6% male), with a median age of 68.5 years (IQR 24). The median follow-up was 7 years (IQR 4), during which 67 (38.1%) patients died. Seventy-three (41.5%) patients had at least one small-bowel angioectasia on capsule endoscopy. On multivariate Cox regression analysis, only age, peripheral arterial disease, history of previous mesenteric ischaemia and chronic kidney disease were independent risk factors of death. The presence of small-bowel angioectasia did not affect survival in this analysis (HR 1.30; 95% CI 0.75-2.23; In this retrospective cohort study, some comorbidities and age were independent predictors of poor survival. The presence of small-bowel angioectasia per se did not affect survival.
