An aim of the present study is to clarify the changes of esophageal function after surgical treatments of the esophageal varices or the congenital esophageal stenosis in children. Esophageal manometric studies were performed in sixteen children undergoing the esophageal transection with paraesophageal devascularization or the esophago-esophagostomy with partial esophagectomy before, within 1 month and over 7 months after the operation.
The pressure of lower esophageal sphincter（LES）, the length of LES, the LES relaxation test and the gastro- esophageal reflux（GER）inducing test were measured.
1） Esophageal transection；The pressure dropped within 1 month and returned to the preoperative level over 11 months after the operation. Temporal deterioration of LES function was observed during the early postoperative days. However, return to the preoperative state was gained over 1 year.
2） Esophago-esophagostomy；The pressure and the length of LES were not changed after the operation. The LES function was disturbed preoperatively and moreover long postoperatively, in the case when congenital stenosis closely existed to the esophago-gastric junction.
Degree of the postoperative disturbance of the LES function may be influenced by the distance to the part of the transection or the partial esophagectomy from the E-C junction.
