A 60-year-old woman with Barrett’s esophagus (Prague class C8M10) with flat high grade dysplasia underwent radiofrequency ablation (RFA) therapy. She underwent four sessions with the circumferential balloon and one treatment with the focal 90 ablation catheter for a total of five sessions. Sessions were performed every 3 months and the patient adhered to maximal acid suppression therapy.

The patient returned for a sixth session (15 months from the start of therapy). Endoscopy showed a 5-cm area of salmon-colored mucosa remaining. There was also a slightly raised 2-cm island that was suspicious for residual neoplasia ([Fig. 1], arrow). The decision was made to perform extensive biopsies to rule out progression of disease. Results showed intramucosal cancer in the raised area while the remaining distal Barrett’s segment was nondysplastic.

Given the presence of refractory Barrett’s mucosa, the decision was made to switch therapy to hybrid argon plasma coagulation (hAPC). The neoplastic island was removed using band ligation endoscopic mucosal resection technique; histology showed intramucosal cancer with negative margins. The EMR defect was treated with hAPC. The mucosa was raised using a submucosal injection (Erbejet, Effect 50; Erbe Elektromedizin GmbH, Tübingen, Germany) and ablated at 40 W ([Video 1]). The remaining distal nondysplastic Barrett’s mucosa was also treated with hAPC at 60 W ([Fig. 2]).

Follow-up endoscopy 3 months later showed minimal islands, which were re-treated with hAPC ([Fig. 3]). Follow-up endoscopy 6 months from the start of hAPC therapy showed complete eradication of intestinal metaplasia ([Fig. 4]), as confirmed by histology from biopsies. The patient tolerated all procedures well and had no post-procedural pain.

This case shows that hAPC is an option when RFA has failed. In our institution we have used hAPC to successfully treat five consecutive cases of disease that was refractory to RFA with or without cryotherapy ([Table 1]).
