ObjectiveTo investigate the timing and clinical efficacy of diaphragmatic plication in the treatment of diaphragmatic paralysis after congenital heart disease (CHD) operation.MethodsFrom January 2013 to February 2019, 30 children with CHD who were treated in Fuwai Hospital were collected, including 17 males and 13 females with a median age of 19.5 (3, 72) months. There were 6 patients with bilateral diaphragmatic paralysis (bilateral group) and 24 patients with unilateral diaphragmatic paralysis (unilateral group). The clinical data of the two groups were compared.ResultsAmong the 6 bilateral diaphragmatic paralysis patients, 2 underwent bilateral diaphragmatic plication, and the other 4 patients continued their off-line exercise after unilateral diaphragmatic plication. Patients in the unilateral group had shorter ventilator use time (266.77±338.34 h vs. 995.33±622.29 h, P=0.001) and total ICU stay time (33.21±23.97 d vs. 67.33±28.54 d, P=0.008) than those in the bilateral group. One patient died in the bilateral group, and there was no statistical difference between the two groups (P=0.363). There was no statistical difference in the ICU stay time after diaphragm plication between the two groups (11.68±10.28 d vs. 29.83±27.73 d, P>0.05).ConclusionDiaphragmatic plication is an effective treatment for diaphragmatic paralysis after CHD operation once the conservative treatment failed. The prognosis of bilateral diaphragmatic paralysis is worse than that of unilateral diaphragmatic paralysis. Strict control of indications for surgery is beneficial to the early recovery of patients.
ObjectiveTo explore the technical feasibility, safety, and short- and long-term efficacy of totally portal minimally invasive thoracoscopic diaphragmatic folding assisted by a stapler for the treatment of symptomatic diaphragmatic eventration in adults. MethodsAretrospective study was conducted on patients with symptomatic diaphragmatic eventration who underwent totally portal minimally invasive thoracoscopic stapler-assisted diaphragmatic folding from August 2021 to February 2025. Surgical time, intraoperative blood loss, postoperative drainage volume, length of hospital stay, and complications were recorded. One month postoperatively, diaphragmatic position, lung function [forced expiratory volume in one second (FEV1), forced vital capacity (FVC) ], and symptom relief were assessed, with extended follow-up to 36 months to monitor long-term efficacy. ResultsA total of 7 patients were included, comprising 3 (42.9%) males and 4 (57.1%) females, with an age range of 34 to 66 years and a mean age of (56.4±12.5) years. All surgeries were successfully completed without conversion to open thoracotomy or intraoperative complications. The average surgical time was (44.29±11.47) minutes, intraoperative blood loss was (25.71±33.09) mL, and the postoperative length of stay was (2.00±0.58) days. One-month follow-up showed that the diaphragmatic position returned to normal anatomical levels, FEV1 improved from preoperative (1.93±0.33) L to (2.36±0.47) L, and the effective rate of clinical symptom relief reached 100.0%. Long-term follow-up (36 months) showed: (1) Pain scores decreased from (1.14±0.38) points at one month postoperatively to (0.14±0.38) points at three months postoperatively, remaining at 0 points at six months and thereafter; (2) All patients had stable diaphragmatic positions with no recurrence; (3) FEV1/FVC was ≥80% at three months postoperatively, with three assessable patients at six months maintaining ≥80%; (4) SpO2 remained ≥95% throughout, with no hypoxic events. ConclusionTotally portal minimally invasive thoracoscopic stapler-assisted diaphragmatic folding is a minimally invasive procedure with rapid recovery, significantly improving lung function and stabilizing diaphragmatic anatomical position. Follow-up at 36 months showed complete pain relief, no recurrence, and long-term stability of lung function, making it a safe and effective surgical option for treating symptomatic diaphragmatic eventration in adults. Long-term efficacy still requires validation with a larger sample size.
