Summary

Blunt abdominal trauma rarely causes hollow visceral injuries, often resulting from high-energy impacts like car crashes without restraints. Early diagnosis is crucial, with peritoneal lavage outperforming CT scans for detecting these severe gut injuries.

Area of Science:

  • Trauma Surgery
  • Abdominal Trauma
  • Gastrointestinal Surgery

Background:

  • Hollow visceral injuries are infrequent in blunt abdominal trauma compared to penetrating injuries.
  • These injuries result from high-energy impacts and are often associated with multiple other traumas.

Purpose of the Study:

  • To analyze the characteristics, mechanisms, and outcomes of blunt hollow visceral injuries.
  • To compare diagnostic modalities for blunt hollow visceral injuries.

Main Methods:

  • Retrospective review of 50 patients with 57 major blunt gut injuries (perforation, transection, devascularization) treated between 1982-1993.
  • Analysis of injury mechanisms, Injury Severity Score (ISS), associated injuries, and diagnostic test results (peritoneal lavage vs. CT scan).

Main Results:

  • Motor vehicle collisions were the primary cause (64%), with unrestrained occupants having significantly higher ISS.
  • Small bowel perforations were most common, followed by devascularization; colonic and gastroduodenal injuries had higher mortality.
  • Peritoneal lavage demonstrated a lower false-negative rate (6.7%) compared to CT scanning (36%) for diagnosing these injuries.

Conclusions:

  • Blunt hollow visceral injuries, though rare, are severe and linked to high-energy trauma and multiple associated injuries.
  • A high index of suspicion and prompt diagnosis, preferably with peritoneal lavage, are essential to improve outcomes and avoid complications.
