Long-term follow-up circular myotomy for XXXX .

Between January 1976 and March 1979, @entity1152 was successfully repaired in six @entity1 with circular myotomy (Livaditis technique) and end-to-end @entity254 . @entity1 were 1 day-6 mo in age and weighed 2.4 to 8.0 kg at the time of repair. Four @entity1 required one and two @entity1 required two circular myotomies in the proximal esophagus to bridge gaps between esophageal ends, which varied from 1.2-3.0 cm. Follow-up has been 1-4 yr (mean-3 yr). Operative complications included: opening of the mucosa at myotomy (2) and @entity834 (2). Subsequently, three @entity1 developed anastomotic stricture which required dilatation. Current x-rays show ballooning of the esophagus at the myotomy site during swallowing in all. However, the esophageal diameter at the myotomy site was never more than 2 cm greater than that of the distal esophagus. In the three @entity1 with anastomotic stricture, mucosal ballooning was not greater than in the others. During follow-up, weights have ranged from the 3rd to the 50th percentile for age. Swallowing has been good in 4, fair in 1 (dilatation still required), and poor in 1 ( @entity85 necessitate @entity3685 ). Circular myotomy offers a safe means of esophageal lengthening. Complications directly related to the myotomy are minimal (mucosal tear) and should be recognized at operation. Ballooning of the mucosa at the myotomy site is a common late finding but diverticulum formation has not occurred. Swallowing and esophageal motility are similar to other @entity1 who have had @entity1152 repair.
