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.
