Comparison of the diagnostic accuracy of CT scan with oral and intravenous contrast versus CT scan with intravenous contrast alone in the diagnosis of blunt abdominal traumas

Diagnosis of small intestinal microperforation by cell morphology detection in abdominal puncture fluid: A case report

INTRODUCTION AND IMPORTANCE

Although abdominal computed tomography angiography (CTA) may be a gold standard for early diagnosis of small intestinal microperforation, early missed and delayed diagnosis are often important factors leading to poor prognosis. The cellular morphology diagnosis of abdominal puncture fluid (DAPF) or diagnostic peritoneal lavage (DPL) may have unexpected clinical outcomes.

CASE PRESENTATION

We report a case of small bowel microperforation which dues to BAT. A 39-year-old male with a chief complaint of "multiple injuries to the whole body from a car accident within 7 hours" was admitted to the trauma center. The first abdominal CTA ruled out perforation of abdominal parenchymatous organs and gastrointestinal tract. Subsequently, the patient underwent emergency surgery for traumatic shock, followed by clinical manifestations of persistent fever and septic shock. After diagnostic abdominal puncture fluid cell morphology examination, intestinal perforation was first considered.

CLINICAL DISCUSSION

Routine examination of abdominal puncture fluid can usually roughly determine the condition of visceral trauma, especially quickly and conveniently determine whether there is intra-peritoneal bleeding. However specific diagnostic components which were found in the cell images of abdominal puncture fluid also showed the clinical value of cellular morphology of DAPF.

CONCLUSION

The cellular morphology examination of DAPF/DPL may be the simplest, fastest, and most effective method for diagnosing small intestinal perforation due to blunt abdominal trauma(BAT). The value of DAPF /DPL in traumatic gastrointestinal injury cannot be ignored, especially for patients with BAT.
