RESUMEN

The esophageal achalasia is an infrequent disease with significant morbidity. Multiple therapeutic alternatives are available with varying results. In 2008, POEM (Peroral Endoscopic Myotomy) endoscopic surgery was initiated in Japan (Inoue, Yokohama). Since then, it has been performed with excellent results. Objective: To describe this technique and the performance of POEM surgery based on a clinical case. Methods: The first POEM surgery was performed in Chile, according to the standards described in Inoue’s technique. It was performed by a single operator with previous training. Original devices were used. Prior informed consent was obtained, at Hospital Padre Hurtado in Santiago in January 2014. Results: A 34-year-old female patient, due to significant dysphagia and weight loss, was fully studied and diagnosed of esophageal achalasia type II. POEM surgery was carried out using the technique described by Inoue. The operating time was 150 minutes. No bleeding or intraoperative complications were detected. Upper endoscopic control at 24 h was normal, initiating progressive oral feeding. Discharged at the 4th postoperative day, without problems after a month. Conclusions: POEM surgery is a safe, effective and replicable treatment for esophageal achalasia in a public hospital in Chile.
