Damage to the Gastrointestinal Tract in Blunt Abdominal Trauma, a Retrospective Assessment.

Introduction: Blunt abdominal trauma is a leading cause of morbidity across all age groups. Traumatic injury to the gastrointestinal tract remains challenging to diagnose early, as clinical signs can be subtle and imaging may miss small perforations. Delayed recognition increases the risk of infection, sepsis, and death. This retrospective study, conducted at the University Hospital of Trauma, aimed to characterize the mechanisms leading to gastrointestinal injury in blunt abdominal trauma and to review the anatomical distribution of lesions, diagnostic approaches, time to presentation, management strategies, complications, and outcomes. The first report of traumatic intestinal injuries dates back to 1899, when Geille reported that traumatic intestinal injuries had an 11% incidence in a group of patients who had undergone Blunt Abdominal Trauma. Some studies said that traumatic intestinal injuries recently ranked third overall in the standings of intra-abdominal injuries in Blunt Abdominal Trauma [3].

Objectives are to: Characterize the mechanisms leading to gastrointestinal injury in blunt abdominal trauma;  Describe the anatomical distribution of lesions; Evaluate diagnostic approaches and time to presentation; Review management strategies, complications, and outcomes.

Materials and Methods: We performed a retrospective review of all blunt abdominal trauma admissions at the University Hospital of Trauma over two years. Inclusion criteria were documented injury to any segment of the gastrointestinal tract. We extracted data on the following: Mechanism of injury, time from injury to hospital presentation, hemodynamic status on arrival, anatomic site of gastrointestinal lesions, diagnostic modalities used (imaging, clinical evaluation), treatment approach (operative vs. non-operative), and complications, morbidity, and mortality.

Results: Out of 257 blunt abdominal trauma patients, 21 (8%) sustained gastrointestinal injuries. Mean age was 32.8 years (range 5–70); age-group distribution: Pediatric (0–14 years): 23.8%; Adult (15–60 years); 62.0%; Geriatric (>60 years): 14.2%. Motor vehicle collisions were the predominant mechanism (33%). Injury sites: Small intestine: 57% and Colon: 43%. All 21 patients underwent laparotomy. Surgical repairs included: Primary closure in 12 cases. Resection with primary anastomosis in 9 cases. 

Conclusion: Gastrointestinal injuries in blunt abdominal trauma comprise a small but critical subset of cases. Early suspicion—especially after high-energy mechanisms—and prompt surgical exploration are key to reducing infectious complications and mortality. Consistent protocols for imaging and clinical monitoring can help expedite diagnosis and improve outcomes. However, it is essential to acknowledge that this study has several limitations, including its retrospective nature and the potential for selection bias, which may have impacted the results.
