Esophageal function following Livaditis repair of long gap esophageal atresia

Proximal pouch esophagomyotomy (Livaditis) allows for repair of long gap esophageal atresia (EA). Postoperative esophageal functional studies in these patients are lacking. Six such infants were followed for up to 42 months. Esophageal function was assessed clinically and by barium swallow, manometry, 24 hr pH monitoring, esophagoscopy, and biopsy. Operative complications included two minor anastomotic leaks and two asymptomatic diverticula at the myotomy site. All patients had dysmotility on barium swallow. Gastroesophageal reflux (GER) was seen in four. Manometry showed a variable aperistaltic segment in each infant but lower esophageal sphincter pressures and relaxation were retained. Twenty-four hour pH monitoring showed an increase in frequency and duration of GER. All four patients biopsied had esophagitis. Five of the six patients showed normal growth velocity. Livaditis modified repair of EA was not associated with significant surgical complications. Esophageal motility showed abnormalities similar to those reported after the standard repair of EA. Myotomy did not adversely affect the esophageal function.
