Youssef HA, Magda MA., Obstruction of small intestine, clinical signs and histopathology in donkeys, Onl J Vet Res., 26 (8): 626-632, 2022. Authors describe strangulation obstruction of small intestine and associated signs and histopathological changes in donkeys. Four groups of 5 adult donkeys each were subjected under general anesthesia to strangulation obstruction of small intestine for 3, 6, 9 or 12h euthanized at 3, 6, 9 and 12 hours postoperatively. Five controls were operated but not obstructed. Clinical examinations were done before surgery and at 3 hour intervals postoperatively. We performed microscopy of obstruction and 10cm, 1, 2 and 3 meters, cranial to it. We found reduced body temperature, but increased respiration, pulse, heart rates and capillary refilling times. At 3h, gross changes at obstruction were congestion, edema and dark red discoloration of intestinal wall and mesentery which increased dramatically at 6, 9 and 12h. Tissue at obstruction at 9 and 12 hours postoperatively showed severe congestion, dark brown to blackish discoloration with fibrous shreds on the strangulated segment. Distension of intestine cranial to the strangulation extended more cranially by increasing the period of strangulation. Petecheal hemorrhages were observed in the intestinal wall and mesentery up to 3 meters. Our findings suggest that surgery should resect normal bowel cranially rather to avoid further lesions.
