The Role of Laparoscopy in the Diagnosis and the Treatment of Missed Diaphragmatic Hernia after Penetrating Trauma

Background: The traumatic diaphragmatic hernia (TDH) may appear acutely after a blunt or penetrating trauma, or it can remain missed also for many years. The discussion about the utility of a laparoscopic repair in acute and chronic TDH is controversial. Methods: In this paper, we present two cases of chronic TDH that were successfully treated with laparoscopy. The first patient was treated 1 year after a stab wound and the second one 10 years after a firearm injury. Results: In both cases, the diaphragmatic defects were easily laparoscopically detected and treated. The defects were repaired with a direct running suture owing to the acceptable dimensions of the tears. The mean operative time was 135 minutes (range, 75–195). The blood loss during the operations was unremarkable. No intraoperative complications occurred, and the conversion rate was null. The postoperative course was uneventful in the first patient, whereas the second patient, owing to the intraoperative respiratory problems, needed an accur...
