Abstract:Objective To explore the safety, feasibility, and clinical effects of thoracoscopic surgery for congenital diaphragmatic hernia and to summarize the surgical experience. Methods The clinical data of 97 child patients with congenital diaphragmatic hernia obtained from the Department of Pediatric Cardiothoracic Surgery of the Children's Hospital of Nanjing Medical University from April 2015 to March 2021 were retrospectively analyzed. The patients, aged 2 days to 3 years ([3.1 ± 7.2] months), consisted of 61 males and 36 females, and 51 cases were left side, and 46 cases were right side. All children underwent diaphragmatic hernia repair under thoracoscopy. During the operation, the contents of the hernia were observed for necrosis, perforation, and injury, and the time of operation, intraoperative blood loss, postoperative thoracic drainage, drainage tube removal time, and hospital stay time after surgery were recorded. Regular follow-up after operation was performed, and the occurrence of related complications, such as incision infection, diaphragm expansion, chylothorax, pneumothorax, intestinal obstruction, and diaphragmatic hernia recurrence after operation were recorded. Results Thoracoscopic surgery was successfully performed in all patients, and none of them switched to traditional surgery. During the operation, the contents of the hernia sac were mostly spleen, stomach, omentum majus, colon, and small intestine, and intestinal perforation, necrosis, liver, and spleen hemorrhage did not occur. The operation time was 75–150 (90.5 ± 12.1) min, the surgical blood loss was 6–15 (8.3 ± 0.6) mL, postoperative thoracic drainage volume was 30–130 (41.2 ± 7.6) mL, drainage tube removal time was 3–10 (6.1 ± 1.3) d, hospital stay after surgery was 10–18 (11.7 ± 2.1) d. During hospitalization, two cases recurred because of the loss of sutures and thus subjected to thoracoscopic surgery again. One case died of severe dysplasia of the left lung on the first postoperative day. A total of 96 child patients were followed up after the operation. The follow-up time ranged from 1 month to 3 years, with an average of 9.2 months. During the follow-up period, no incision infection, chylothorax, respiratory tract infection, intestinal obstruction, and intestinal perforation were observed. The children grew well and did not suffer a recurrence. Conclusions Total thoracoscopic surgery for the treatment of congenital diaphragmatic hernia in infants has the following advantages: clear surgical field of vision, decreased blood loss during operation, decreased postoperative complications, and short hospital stay. The short-term curative effect is reliable, safe, and feasible.
