Plain-English summary
A 5-year-old Beagle was brought in for vomiting and lethargy due to an intestinal blockage caused by a foreign object. The veterinarian used a special imaging technique to assess the blood flow in the dog's intestines and determined the best surgical approach. Both hand-sewn and stapled methods for removing the damaged section of the intestine were found to be equally effective in preserving blood flow. The dog recovered well after surgery and was able to return to normal activities.

Abstract
OBJECTIVE: To investigate sidestream dark field (SDF) videomicroscopy as an objective measure of intestinal viability and determine the effects of enterectomy techniques on intestinal microvasculature in dogs with foreign body obstructions. STUDY DESIGN: Prospective, randomized, clinical trial. ANIMALS: A total of 24 dogs with an intestinal foreign body obstruction and 30 systemically healthy dogs. METHODS: An SDF videomicroscope imaged the microvasculature at the site of the foreign body. Subjectively viable intestine received an enterotomy whereas nonviable intestine received an enterectomy using a handsewn (4-0 polydioxanone, simple continuous) or a functional end-to-end stapled technique (GIA 60 blue, TA 60 green) was used on an alternating basis. The microvasculature adjacent to the enterectomy was interrogated. Quantitative measures of microvascular health were calculated for each site and compared with healthy dogs. RESULTS: Microvascular density (mean ± SD) at the site of obstruction (140.84 ± 77.40) was lower than healthy controls (251.72 ± 97.10, p < .01). There was no difference in microvascular parameters (density or perfused boundary region, PBR) between obstructed dogs with subjectively viable and nonviable intestine (p > .14). The density (p = .66) and PBR of microvessels (p = .76) adjacent to the sutured enterectomy or TA green staple line did not differ. CONCLUSION: Sidestream dark field videomicroscopy can identify obstructed intestine and quantitate the severity of microvascular compromise. Handsewn and stapled enterectomies equally preserve perfusion. CLINICAL SIGNIFICANCE: Stapled enterectomies do not lead to greater vascular compromise than handsewn enterectomies.
