Abstract

PURPOSE:

To evaluate the safety and efficacy of transcatheter arterial embolization with N-butyl cyanoacrylate (NBCA) for the treatment of gastrointestinal (GI) bleeding via a meta-analysis of published studies.

MATERIALS AND METHODS:

The MEDLINE/PubMed and EMBASE databases were searched for English-language studies from January 1990 to March 2016 that included patients with nonvariceal GI bleeding treated with transcatheter arterial embolization with NBCA with or without other embolic agents. The exclusion criteria were a sample size of < 5, no extractable data, or data included in subsequent articles or duplicate reports.

RESULTS:

The cases of 440 patients (mean age, 63.8 y ± 14.3; 319 men [72.5%] and 121 women [27.5%]) from 15 studies were evaluated. Of these patients, 261 (59.3%) had upper GI bleeding (UGIB) and 179 (40.7%) had lower GI bleeding (LGIB). Technical success was achieved in 99.2% of patients with UGIB (259 of 261) and 97.8% of those with LGIB (175 of 179). The pooled clinical success and major complication rates in the 259 patients with UGIB in whom technical success was achieved were 82.1% (95% confidence interval [CI], 73.0%-88.6%; P = 0.058; I2 = 42.7%) and 5.4% (95% CI, 2.8%-10.0%; P = 0.427; I2 = 0.0%), respectively, and those in the 175 patients with LGIB in whom technical success was achieved were 86.1% (95% CI, 79.9%-90.6%; P = 0.454; I2 = 0.0%) and 6.1% (95% CI, 3.1%-11.6%; P = 0.382; I2 = 4.4%), respectively.

CONCLUSIONS:

Transcatheter arterial embolization with NBCA is safe and effective for the treatment of GI bleeding.
