Abstract: Congenital diaphragmatic hernia (CDH) in adults is rare and often misdiagnosed,leading to delayed treatment.A 29-year-old male patient was admitted on November 21,2024,with progressive dyspnea.CT imaging revealed a left diaphragmatic defect with massive herniation of abdominal organs into the thoracic cavity.On the sixth day of hospitalization,the patient underwent laparoscopic tension-free repair of the left diaphragmatic hernia.Intraoperatively,a 5cm diaphragmatic defect was observed,and the herniated contents were successfully reduced into the abdominal cavity and secured with a mesh.The postoperative recovery was good,with full lung re-expansion and no significant complications.No recurrence was observed during the 3-month follow-up.

Key words: diaphragmatic hernia, congenital diaphragmatic hernia, bochdalek hernia, laparoscopic tension-free repair surgery
