Results
Results of our analysis are listed below:
Types of ASBI in our sample:
-7% of our patients had an evidence of ASBI from vascular (arterial/venous) occlusion;
- 12% of our sample had ASBI due to hypovolemic insult or a low flow state;
- in 81% of our cases,
ASBI was a consequence of bowel obstruction.
Analysis of every single CT sign associated with ASBI:
-Altered bowel wall enhancement and thickness resulted almost always present in patients with ASBI due to a vascular occlusion or a low flow state (primary bowel ischemia),
differently from patients with bowel obstruction (p< 0.001).
-Patients with ASBI due to a vascular occlusion or a low flow state presented more frequently with intramural bowel gas than patients with bowel obstruction and underwent bowel resection under surgery (p=0.001).
-Free abdominal fluid was almost equally represented in the three categories of our sample (p=0.105).
