Evaluation and validation of a new score to measure the severity of small-bowel angiodysplasia on video capsule endoscopy (cesbai)

Introduction: Angiodysplasias are responsible of 50 % of small bowel bleeding. An endoscopic method that allows measuring its severity is not available Aims: 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 three variables: A. Extent of lesions: E1: located in one half of the intestine and E2:in both halves. B. Number of lesions: N110 lesions. C. Probability of bleeding: P1: pale red spots; P2: bright red spots; P3: bleeding stigmata and P4: active bleeding. CESBAI was calculated as follows: E x 1 + N x 2 + P x 3. Interobserver variability was analyzed by the Spearman's correlation and agreement Kappa statistic tests. Results. The mean CESBAI scores by observers (O) were: O1= 11.6 ± 4.1; O2 =: 11.3 ± 4.8; O3 = 11.1 ± 4.9 and O 4 = 11.8 ± 4.2 (p>0.05). Spearman ’s correlation values of CESBAI between every two observers were from 0.61 to 0.94 ( p
