| Abstract |
Small-bowel angioectasias are frequently diagnosed with capsule endoscopy (CE) or balloon endoscopy however, major predictors have not been defined and the indications for endoscopic treatment have not been standardized. The aim of this study was to evaluate the predictors and management of small-bowel angioectasia. Among patients with obscure gastrointestinal bleeding (OGIB) who underwent both CE and double-balloon endoscopy at our institution, we enrolled 64 patients with small-bowel angioectasia (angioectasia group) and 97 patients without small-bowel angioectasia (non-angioectasia group). The angioectasia group was subdivided into patients with type 1a angioectasia (35 cases) and type 1b angioectasia (29 cases) according to the Yano-Yamamoto classification. Patient characteristics, treatment, and outcomes were evaluated. Age (P = 0.001), cardiovascular disease (P = 0.002), and liver cirrhosis (P = 0.003) were identified as significant predictors of small-bowel angioectasia. Multivariate logistic regression analysis identified cardiovascular disease (odds ratio 2.86; 95 % confidence interval, 1.35-6.18) and liver cirrhosis (odds ratio 4.81; 95 % confidence interval, 1.79-14.5) as independent predictors of small-bowel angioectasia. Eleven type 1a cases without oozing were treated conservatively, and 24 type 1a cases with oozing were treated with polidocanol injection (PDI). Re-bleeding occurred in two type 1a cases (6 %). Seventeen type 1b cases were treated with PDI and 12 type 1b cases were treated with PDI combined with argon plasma coagulation (APC) or clipping. Re-bleeding occurred in five type 1b cases (17 %) that resolved after additional endoscopic hemostasis in all cases. There was one adverse event from endoscopic treatment (1.6 %). Cardiovascular disease and liver cirrhosis were significant independent major predictors of small-bowel angioectasia. Type 1a angioectasias with oozing are indicated for PDI and type 1b angioectasias are indicated for PDI with APC or clipping. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 May 2016.
All research outputs
#17,770,433
of 22,824,164 outputs
Outputs from BMC Gastroenterology
#1,033
of 1,745 outputs
Outputs of similar age
#180,629
of 267,539 outputs
Outputs of similar age from BMC Gastroenterology
#22
of 40 outputs
Altmetric has tracked 22,824,164 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,745 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 267,539 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 40 others from the same source and published within six weeks on either side of this one. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
