Esophageal manometrical assessment after esophageal circular myotomy for wide-gap esophageal atresia

We treated 3 children with wide-gap esophageal atresia by a circular myotomy of Livaditis technique, after which no postoperative complaints, such as heartburn, vomiting or dysphagia, were seen. Esophageal manometry, performed to evaluate the postoperative esophageal motor function revealed; (1) that lower esophageal sphincter pressure (LESP) increased gradually with time, (2) esophageal contraction waves (ECW) were evident at the site of the circular myotomy with swallowing, though these contractions were simultaneous; and (3) relaxation of the LES with swallowing was evident. These findings, as determined by the esophageal manometrical assessments, indicate that there is no difference between the postoperative esophageal function after either repair with a circular myotomy or primary anastomosis for esophageal atresia.
