Early esophageal carcinomas in achalasia patient after endoscopic submucosal dissection combined with peroral endoscopic myotomy: A case report

Abstract

BACKGROUND Achalasia is associated with high risk of esophageal carcinoma. However, the optimal endoscopic surgery for patients with early esophageal carcinoma concomitant with achalasia remains unclear. CASE SUMMARY A combination of concurrent endoscopic submucosal dissection (ESD) and modified peroral endoscopic myotomy (POEM) was performed on a 62-year-old male, who presented with multiple early esophageal carcinomas concomitant with achalasia. The patient exhibited an improvement in feeding obstruction, and presented no evidence of disease during the 3-year follow-up. CONCLUSION The combination of ESD and POEM is a feasible treatment modality for patients with early esophageal carcinoma concomitant with achalasia.
