**Abstract**

Of the several procedures that has to treat esophageal achalasia, the esophagectomy is to be the most indicated in advanced disease, which prompted Pinotti the disseminate the transmediastinal esophagectomy technique in the 1970s, with the advantage of avoiding thoracotomy. Nevertheless, several series demonstrated that this technique was not exempt from complications one of which could lead to massive hemopneumothorax due to injury to the trachea- bronchial tree and vessels due the periesophagitis that may be present with consequent adherence of the esophagus to these noble organs. Thus, Aquino in 1996 introduced the esophageal mucosectomy technique with preservation of the esophageal muscle tunic at the level of mediastinum as well as the transposition of the stomach to the cervical region inside in this tunic for the reconstruction of digestive tract. The advantage of this procedure is to avoid transgression of the mediastinum. This author describes in details this procedure, and shows early results and late evaluation using the ECKARDT score in a series of patients showing the advantages of the esophageal mucosectomy due the low incidence of immediate postoperative complications and good resolution in long term due the absence of symptoms in most patients.
