Most patients with cirrhosis and portal hypertension eventually require liver transplantation. Esophageal neoplasia in this population (especially in patients who use alcohol and tobacco) might contraindicate liver transplantation. Early Barrett’s neoplasia should be treated with endoscopic resection if there are no signs of advanced adenocarcinoma, and complete eradication of all remaining Barrett’s epithelium should be striven for, preferably with radiofrequency ablation (RFA) [1]. However, these treatments may become challenging in patients with portal hypertension and esophageal varices, due to the risk of variceal bleeding and hepatic decompensation. Some reports have been published of endoscopic resection after a session of endoscopic variceal ligation, but without RFA for eradication therapy [2] [3]. We present a case series of three patients with esophageal varices and Barrett’s neoplasia successfully treated with a modified endoscopic resection technique and RFA ([Table 1]).

* In case 1 there was poor adherence to treatment and follow-up, with no surveillance endoscopy after the last RFA session.
Esophageal varices were confirmed by endoscopic ultrasound on prior endoscopy. All procedures were performed with the patient under deep sedation, and with antibiotic prophylaxis and somatostatin perfusion. After identifying and marking the target lesion, we “blocked” the distal-to-proximal variceal flow by endoscopic band ligation of visible esophageal varices distal to the lesion. Conventional band ligation-assisted endoscopic mucosal resection (EMR) of the target lesion was then performed in the same session ([Fig. 1], [Fig. 2]). Another EMR session was used if needed. When the lesions were completely removed, RFA was performed in a further session until complete eradication of Barrett’s esophagus was achieved ([Video 1], Case 3). No intraprocedural complications occurred. One patient presented delayed bleeding 8 days after EMR, but this did not require endoscopic treatment. No other relevant complications were seen.

Video 1 Modified technique for endoscopic mucosal resection followed by radiofrequency ablation for eradication of neoplastic Barrett’s esophagus in the presence of esophageal varices.
Quality:
In conclusion, EMR of dysplastic lesions in Barrett’s esophagus with underlying esophageal varices, followed by RFA for complete eradication, is feasible. The use of band ligation to decrease the blood flow prior to EMR may be helpful.
