- W4376453361 abstract "Background Endoscopic ablation of Barrett's esophagus has been described in which various thermocoagulation modalities are used in combination with a high dose of a proton pump inhibitor. No randomized comparison of ablation strategies has been published. Methods Referred patients were screened to identify those with Barrett's esophagus 2 to 7 cm in length, without high-grade dysplasia or cancer. Included patients received pantoprazole (40 mg twice a day), followed by randomization to treatment with argon plasma coagulation (APC) or multipolar electrocoagulation (MPEC). The primary outcome measure was the number of treatment sessions required for endoscopic ablation. Results Of 235 patients screened, 52 were randomized. The mean length of Barrett's esophagus was 3.1 cm in the MPEC group vs. 4.0 cm in the APC group (p = 0.03). Otherwise, the treatment groups were similar with regard to baseline characteristics. The mean number of treatment sessions required for endoscopic ablation was 2.9 for MPEC vs. 3.8 for APC (p = 0.04) in an intention-to-treat analysis (p = 0.249, after adjustment for the difference in length of Barrett's esophagus). The proportion of patients in which ablation was endoscopically achieved proximal to the gastroesophageal junction was 88% for the MPEC group vs. 81% for the APC group (p = 0.68) and histologically achieved in 81% for MPEC vs. 65% for APC (p = 0.21). The mean time required for the first treatment session was 6 minutes with MPEC vs. 10 minutes with APC (p = 0.01) in per protocol analysis. There was no serious adverse event, but transient moderate to severe upper-GI symptoms occurred after MPEC in 8% vs. 13% after APC (p = 0.64). Conclusions Although there were no statistically significant differences, ablation of Barrett's esophagus with pantoprazole and MPEC required numerically fewer treatment sessions, and endoscopic and histologic ablation was achieved in a greater proportion of patients compared with treatment with pantoprazole and APC.
