[Reoperation of esophageal achalasia].

From 1980 to 1989, 18 patients with esophageal achalasia had postoperative restricture. Inadequate myotomy was shown in 7 patients, scar constriction in 5, gastroesophageal reflux in 3, and paraesophageal hiatus hernia in 1. Seventeen patients underwent reoperation including modified myotomy (11), esophagastrotomy (4), operation for esophageal hiatus hernia (1), and cardioplasty combined with fundoplication (1). The causes of restricture, diagnostic methods, operative procedure and methods of precaution are discussed.
