Treatment of long-segment Barrett's adenocarcinoma by complete circular endoscopic submucosal dissection: A case report

Abstract

Background: We present the first description of en bloc endoscopic submucosal dissection (ESD) for total circumferential Barrett's adenocarcinoma, predominantly of the long-segment Barrett's esophagus (LSBE), with a 2-year follow-up and management strategies for esophageal stricture prevention. Case presentation: A 59-year-old man was diagnosed with LSBE and Barrett's adenocarcinoma by esophagogastroduodenoscopy (EGD). A 55-mm-long circumferential tumor was completely resected by ESD. Histopathology revealed a well-differentiated adenocarcinoma within the LSBE superficial muscularis mucosa. For post-ESD stricture prevention, the patient underwent an endoscopic triamcinolone injection administration, oral prednisolone administration, and preemptive endoscopic balloon dilatation. Two years later, there is no evidence of esophageal stricture or recurrence. Conclusions: ESD appears to be a safe, effective option for total circumferential Barrett's adenocarcinoma in LSBE.
