Delayed presentation of traumatic diaphragmatic hernia.

Area of Science:

• Trauma Surgery
• Thoracic Surgery
• Abdominal Surgery

Background:

• Traumatic diaphragmatic hernia (TDH) can result from penetrating or blunt force injuries.
• Delayed diagnosis of TDH is common, often presenting months after the initial trauma.
• Left-sided TDH is more prevalent due to anatomical factors.

Purpose of the Study:

• To describe the clinical characteristics, diagnostic methods, and surgical outcomes of patients with delayed traumatic diaphragmatic hernia.
• To evaluate the efficacy of different surgical approaches for repairing TDH.

Main Methods:

• Retrospective review of 25 patients with TDH diagnosed at least five months post-injury.
• Analysis of etiological factors (stab wounds vs. blunt trauma), diagnostic modalities (radiography, barium studies, gastric drainage), and surgical techniques (thoracotomy, thoracoabdominal, abdominal approaches).

Main Results:

• 22 of 25 cases resulted from stab wounds, with 24 hernias on the left side.
• Radiography was the primary diagnostic tool; barium studies and gastric drainage aided diagnosis in some cases.
• Thoracotomy or thoracoabdominal incisions facilitated easier repair compared to abdominal approaches in some instances.
• Commonly involved organs included the stomach and colon; strangulation occurred in five patients.
• Overall mortality was 20%, increasing to 80% in cases with gangrene.

Conclusions:

• Delayed diagnosis of TDH is a significant challenge, often linked to penetrating trauma.
• Surgical approach influences repair ease and success, with thoracic routes sometimes preferred.
• High mortality rates associated with strangulation and gangrene underscore the urgency of timely diagnosis and intervention.
