Clinical Trial Summary

Recommended therapies for esophageal achalasia are endoscopic pneumatic dilation and Heller-Dor surgical myotomy. Endoscopic myotomy has been recently proposed in human patient in expert centers in Japan, US and Germany. In theory, endoscopic myotomy is as effective as surgical myotomy but less invasive and more effective with less complications than endoscopic pneumatic dilation. Up to now, published studies have confirmed these expectations, with 100% efficacy and no clinically significant complications. The present clinical trial with study the security and efficacy of peroral endoscopic myotomy in primary achalasia patients.

Intervention

Procedure:
Peroral endoscopic myotomy
An endoscopy is performed under anesthesia with orotracheal intubation. After submucosal saline injection, an entry point in the submucosal space is created at 10 cm above the cardia. The endoscope will create a 12cm long tunnel in the caudal direction by submucosal dissection, stopping at 2cm below cardia. Then the muscular circular internal layer is sectioned on a 9cm length, starting 3 cm below the submucosal entry point. At the end the submucosal entry point is closed with metallic clips. A scanner is performed after the procedure so as to check the esophageal wall integrity. Alimentation is progressively introduced at day 1. This is a study of a procedure - peroral endoscopic myotomy (POEM). No new, unapproved device is used. All endoscopic tools are already approved for endoscopic submucosal dissection and associated complications (hemorrhage or perforation): dissection knifes, hot biopsy forceps, endoscopic metallic clips.

elevated white blood count with elevated neutrophils and elevated CRP, ascending values
subcutaneous emphysema, pneumomediastinum, penumoperitoneum seen at imaging studies (day 1 CT scan)
Day 1 after procedure Yes
Secondary percentage of patients with Eckardt score less than 3 Eckardt score calculated at baseline and after procedure at 3rd and 12th month after procedure No
Secondary significant variation of Eckardt score Eckardt score calculated at baseline and after procedure at baseline and at 1st, 3rd, 6th and 12th month after the procedure No
