[Idiopathic megaesophagus in the child. A series of 8 cases (author's transl)]

The authors report a series of 8 cases of idiopathic Megaesophagus in the child. Age distribution is between 5 and 15 years: 4 boys and 4 girls. Clinical signs are dominated by dyphagia and thinness. Heller's operation modificated by J.L. Lortat-Jacob and completed by reconstitution of His's angle, via an abdominal approach, is the operation proposed. No recurrence of Megaesophagus was seen. However, in two cases, a hernia of mucosa occurred, without any clinical symptom. Long term results were favourable (follow up between 7 years and 10 months).
