ABSTRACT
INTRODUCTION:
Angiodysplasias are responsible of 50% of small bowel bleeding. An endoscopic method that allows measuring its severity is not available.AIMS:
The aim of the study was to validate a new endoscopic score with VCE to measure the severity of small bowel angiodysplasias (SBAD).METHODS:
Four endoscopists independently reviewed VCE videos of 22 patients with SBAD. The score graded 3 variables A - extent of lesions E1, located in one half of the intestine and E2, in both halves; B - number of lesions N1, <5; N2, 5-10; and N3, >10 lesions; C - probability of bleeding P1, pale red spots; P2, bright red spots; P3, bleeding stigmata; and P4, active bleeding. Capsule Endoscopy Small Bowel Angiodysplasia Activity Index (CESBAI) was calculated as follows E × 1 + N × 2 + P × 3. Interobserver variability was analyzed by Spearman's correlation and agreement Kappa statistic tests.RESULTS:
The mean CESBAI scores by observers were O1= 11.6 ± 4.1; O2 = 11.3 ± 4.8; O3 = 11.1 ± 4.9; and O4 = 11.8 ± 4.2 (p > 0.05). Spearman's correlation values of CESBAI between every 2 observers were from 0.61 to 0.94 (p < 0.001) with a global correlation of 0.73 among all observers. Kappa values of CESBAI between every 2 observers ranged from 0.42 to 0.87 (p < 0.001) with a global agreement of 0.57 among all observers. All evaluators stated that the method was easy to use.CONCLUSIONS:
CESBAI is a reliable and reproducible score. Nevertheless, these results must be validated in other studies with larger population before assessing its power for predicting bleeding recurrence.Palavras-chave
