Abstract: Objective:To explore the feasibility, surgical experience and therapeutic outcomes of video-assisted thoracoscopy for esophageal diverticulum after congenital esophageal atresia(CEA).Methods:From November 2018 to May 2021, clinical data were retrospectively reviewed for 5 children undergoing thoracoscopic resection of esophageal diverticulum after CEA.There were 1 boy and 4 girls with a median age of 12.8(6.3-36.0) months and a median body weight of 8.0(6.5-10.5) kg.Operative duration, amount of blood loss, length of hospitalization stay, postoperative complications and follow-up results were recorded.Results:All operations were completed successfully.Average operative duration was 2.3(1.5-3.6) hours and amount of blood loss <5 ml.No intraoperative blood transfusion was required.During a stay of pediatric intensive care unit(PICU), mean postoperative time of using invasive ventilator was 3(1-7) days and mean postoperative hospital stay 16(10-21) days.Upper gastrointestinal angiography hinted at anastomotic leakage at Week 1 postoperatively and the child recovered spontaneously within a week.During a follow-up period of (1-30) months, all of them resumed a normal diet and both growth and development were decent.Conclusions:Esophageal diverticulum is rare after CEA.Its common clinical manifestations include dysphagia, coughing during ingestion and recurrent upper respiratory tract infection.Thoracoscopy is both safe and effective for thoracic esophageal diverticulum.
