[Achalasia of the esophagus: modified Heller's esophagomyotomy and floppy Nissen fundoplication, via the abdomen].

Six patients with achalasia of the esophagus were submitted to an abdominal esophagomyotomy which extended two centimeters in width and six to eight centimeters in length, descending one or two centimeters from the esophagealgastric union without having to remove the mucosa in 50% of the esophageal circumference while also performing total funduplication of the floppy Nissen type. The clinical evaluation showed the disappearance of all symptoms. Both the endoscopic as well as the X-rays studies showed the obsence of obstructive symptoms or reflux of any sort.
