🔍 Key Findings
- Microvascular density at the site of foreign body obstruction was significantly lower in obstructed dogs compared to healthy controls.
- PBR (perfused boundary region) was paradoxically lower in obstructed dogs, indicating that PBR may not reliably correlate with tissue viability in this context.
- No significant difference in microvascular perfusion between subjectively viable vs nonviable intestines, suggesting subjective assessment is unreliable.
- No difference in perfusion parameters between handsewn and stapled enterectomies, indicating both techniques preserve vascular health equally.
- Stapled enterectomy using green TA staples is safe and did not impair intestinal perfusion at the anastomosis site.
- SDF videomicroscopy is feasible intraoperatively and can differentiate healthy from diseased intestine in dogs.
- Surgeons' subjective evaluations led to potentially unnecessary enterectomies, as microvascular parameters did not differ.
- No cases of dehiscence or mortality, suggesting both surgical approaches are effective when applied properly.
