Radiofrequency ablation (RFA) vs. argon plasma coagulation (APC) for the management of gastric antral vascular ectasia (GAVE) in patients with and without cirrhosis: results from a retrospective analysis of a large cohort of patients treated at a single center.
Endoscopy International Open 2018 March
INTRODUCTION AND STUDY AIMS: Gastric antral vascular ectasia (GAVE) is a mucosal abnormality associated with multiple conditions, most notably cirrhosis and systemic sclerosis, that causes indolent gastrointestinal bleeding. It is primarily managed with endoscopic therapy. Traditionally, GAVE is endoscopically ablated using argon plasma coagulation (APC) but radiofrequency ablation (RFA) is emerging as an alternative modality. No prior comparison of the 2 modalities has been published.
PATIENTS AND METHODS: After receiving IRB approval, we reviewed our electronic health records to identify all patients who underwent endoscopic evaluation for GAVE between January, 2011 and October, 2016. We compared important variables between APC and RFA, as well as between cirrhosis and non-cirrhosis, using the Chi-square test and the Wilcoxon two-sample test as appropriate.
RESULTS: During our study period, 81 patients were endoscopically evaluated for GAVE. 24 patients were treated with APC alone, 28 with RFA alone and 25 patients received both treatment modalities.
CONCLUSIONS: RFA and APC were both effective in treating bleeding from GAVE. Though we found subtle differences, patients underwent a similar number of treatment sessions and had similar procedure times and a similar time between sessions no matter the treatment modality used.
