Dig Dis Sci: Identification of re-bleeding and high-risk patients with small intestine angiodulation disorder

Since 2001, small intestine capsule endoscopy (SBCE) has been widely used in the investigation of small intestine lesions, and small intestine capsule endoscopy (SBCE) is the gold standard for the examination of suspected small intestine haemorrhage (SBB).
blood vessel dilation is the most common vascular abnormality in the gastrointestinal tract, which is reported to be the main cause of intestinal bleeding in up to 80% of SBB patients.
the study was to identify some of the characteristics and possible independent predictors of re-bleeding in patients with small intestine vascular dilation in SBCE.
this study is a retrospective study that included patients who under had a SBCE test between April 2008 and December 2017 accompanied by blood vessel dilation, all of which were followed up for at least 12 months.
is defined as a drop in hemoglobin ≥2 g/dl and/or intestinal bleeding in the presence of an esophagic gastroenteroscopy and a return colonoscopy.
researchers collected clinical data from medical records and classified vascular dilation by number, location, size and type.
single-variable and multivariable statistical analysis to determine possible re-bleeding predictors.
study included 630 patients who had SBCE tests on suspicion of SBB, 129 of whom had vasodulation.
women accounted for 59.7 per cent, with a medium age of 72 (19-91) years and an average follow-up of 44.0±31.9 months.
at least one re-bleeding was recorded in 32.6% of patients .42.
heart failure (OR 3.41; 95％CI 1.18–9.89; p - 0.024), degree of vascular dilation (OR 5.41; 95％CI 2.15-13.6; p slt;0.001) and smoking status (OR 3.15; 95% CI 1.07-9.27; p s 0.038) is an independent predictive factor for re-bleeding.
the authors of this study found that heart failure, smoking status and vascular dilation larger than 5 mm were independent predictive factors for re-bleeding in blood vessel dilation populations diagnosed by SBCE.
