Upper Gastrointestinal Bleeding as Delayed Presentation of Traumatic Diaphragmatic Hernia; a Case Report.

Abstract

Introduction: Traumatic diaphragmatic hernia (TDH) is one of the critical complications resulting from penetrating chest trauma. The rate of undiagnosed TDH equivocates 12-60%. The significant part of complications happens 1-4 years after the primary damage. Here, we report a case of delayed TDH presented with upper gastrointestinal bleeding (GIB) as an excuse to discuss this issue.

Case presentation: The patient was a 35-year-old man, admitted with objection of abdominal pain. A nasogastric tube was inserted and fixed that resulted in drainage of about 500cc dark blood. He was candidate for emergent endoscopy due to upper GIB. During resuscitation measures, he suddenly developed respiratory distress that could not be justified by upper GIB alone. Therefore, bedside sonography discovered some soft tissue apart from lung tissue in the left hemithorax. After performing diagnostic measures, with diagnosis of diaphragmatic herniation and strangulation he underwent emergent surgery.

Conclusion: Small diaphragmatic lesions, which usually result from stab wounds, may develop into larger injuries if left untreated and they might lead to a diaphragmatic hernia with a potential risk of early or late complications and mortality. One of the rare complications is GIB, which should be considered in a patient with past history of trauma and presentation of GIB.
