Combination of concurrent endoscopic submucosal dissection and modified peroral endoscopic myotomy for an achalasia patient with synchronous early esophageal neoplasms

Abstract

Achalasia is generally accepted as a condition associated with an increased risk for developing esophageal squamous cell carcinoma. In our paper, we introduced an achalasia patient combined with synchronous early esophageal neoplasms. We performed a combination of concurrent endoscopic submucosal dissection (ESD) and peroral endoscopic myotomy (POEM). No complications other than postoperative pain that needed morphine treatment for two days had occurred. Dysphagia was significantly improved. Neither reflux nor cough occurred. The short-term efficacy and safety of our case is favorable and suggests that concurrent ESD and POEM could be a treatment option to such patients.

Case of Concomitant Endoscopic Treatment of Achalasia with Superficial Esophageal Cancer

“…Few cases where achalasia and superficial esophageal cancer were treated simultaneously have been reported (Table 1). 10,11 In one case, concurrent chemoradiotherapy was performed on a patient with achalasia and advanced esophageal cancer. 12 In other cases, ESD for esophageal cancer was performed either before or after POEM for achalasia rather than at the same time.…”
