[Heller's operation in the treatment of idiopathic megaesophagus. Apropos of 25 cases].

The authors report 25 cases of idiopathic mega-oesophagus treated by Heller's myotomy via an abdominal incision with prevention of gastro-oesophageal reflux by means of Toupet, Dor or Nissen procedures. The results, with a follow-up of 2 to 13 years, were considered to be good in 82% of cases with 2 moderate results (9%) and two failures (9%). The authors consider Heller's operation to be the operation of choice in preference to forced dilatations.
