H. Neugebauer et al., Seventy cases of injuries of the small intestine caused by blunt abdominaltrauma: A retrospective study from 1970 to 1994, J TRAUMA, 46(1), 1999, pp. 116-121
Background: Injuries of the hollow viscera are far less common in blunt abd
ominal trauma than in penetrating abdominal trauma. This article is a 25-ye
ar retrospective study of 70 patients with injuries of the small intestine
caused by blunt trauma. All patients were treated surgically at the trauma
hospital (Unfallkrankenhaus) in Graz, In our series, blunt abdominal trauma
causing hollow viscus injuries occurred in conjunction with multiple traum
a in 68.8% of cases. The overall mortality rate was 25.7%,
Methods: The following methods were used for evaluating the intestinal inju
ry: detailed history of the accident and examination of the patients (eg.,
transverse abdominal bruise) diagnostic peritoneal lavage before 1984, abdo
minal sonography since 1984, computed tomography, and laboratory tests.
Results: Prognosis and results depended partly on the general condition of
the patient, as web as the timeliness of diagnosis and surgical management
of the small bowel injury. Delays in diagnosis were common because of the o
verall condition of the patient, as well as the difficulty in establishing
a definitive diagnosis by using current radiologic and serologic modalities
.
Conclusion: It should be stated that the high mortality of small bowel inju
ries after blunt abdominal trauma justifies an aggressive approach to diagn
osis and surgical treatment of these injuries. This article focuses on inju
ry mechanisms and current concepts in diagnosis and the therapy of small in
testine lacerations in blunt abdominal trauma.
