Diaphragm replacement: An experimental animal study

Delayed traumatic diaphragmatic hernias presenting with strangulation

Traumatic diaphragmatic injuries commonly occur following blunt and penetrating trauma, and that may be missed during a first evaluation, resulting in chronic diaphragmatic hernia and/or strangulation. In this study, we present three cases of delayed traumatic diaphragmatic hernias presenting with strangulation. The type of trauma was blunt in two and penetrating in one patient. In all three cases, the diagnoses of diaphragmatic injuries were missed in acute and chronic settings. While two patients had transverse colonic strangulation, the other one had strangulated stomach and spleen. Transverse colon resection was performed in one patient. Two patients had postoperative complications, and no postoperative mortality was detected. Patients complaining of upper abdominal pain and dyspnea with past history of thoracoabdominal trauma should be evaluated for a missed diaphragmatic injury. A high index of suspicion, physical examination of the chest, and x-ray film are helpful for diagnosis of delayed traumatic diaphragmatic hernias presenting with strangulation.

Late bilateral diaphragmatic rupture: Challenging diagnostic and surgical repair

A 67-year-old man was referred to our department, after a vehicle accident, with multiple bone fractures and a left blunt diaphragmatic rupture. An emergency laparatomy was performed, and the left diaphragmatic defect directly sutured. Postoperatively, a delayed right diaphragmatic rupture occurred due to progressive inflammation and muscle devitalisation. The diagnosis was challenging because the right rupture became clinically evident later after extubation. Diaphragmatic reconstruction was performed through a right thoracotomy. A high index of suspicion should always be observed for missed or delayed bilateral diaphragmatic ruptures.

Surgical embryology and anatomy of the diaphragm with surgical applications

This article reviews the development, surgical anatomy, and teratology of the diaphragm, and discusses the diagnostic procedures, surgical therapy, and prognosis of congenital disturbances. Special attention is paid to the traumatic rupture of the diaphragm, concerning incidence, cause, diagnosis, prognosis, and surgical repair.
