Laparoscopic Repair of a Chronic Diaphragmatic Hernia

Abstract

Diaphragmatic injuries that remain undetected after an acute traumatic event may lead to the formation of a diaphragmatic hernia. Symptoms of a chronic diaphragmatic hernia are related to the incarceration of abdominal contents in the defect or to impingement of the lung, heart, or thoracic esophagus by abdominal viscera. A 49-year-old woman with a symptomatic chronic diaphragmatic hernia from an unrecognized iatrogenic injury to the left hemidiaphragm sought treatment. The diaphragmatic injury occurred 2 years earlier when a low, left-sided chest tube was placed for a persistent pleural effusion 2 weeks after a lower lobectomy for an aspergilloma. The patient's diaphragmatic hernia was diagnosed after an upper gastrointestinal series and an esophagogastroduodenoscopy. Approximately 75% of her stomach was incarcerated in the diaphragmatic defect. The diaphragmatic hernia was repaired laparoscopically using a 9 cm x 10-cm polytetrafluoroethylene patch sewn with nonabsorbable, interrupted, horizontal mattress sutures. Improvement of video technology, laparoscopic instruments, and surgical skills has allowed surgeons to expand the boundaries of advanced therapeutic laparoscopy. These factors facilitated the authors' standard tension-free prosthetic repair of a chronic diaphragmatic hernia using minimally invasive techniques.
