Abstract
ABSTRACT: A 48-hour-old mixed breed pony colt was referred to the hospital because of abdominal discomfort, weak suckling reflex and prostration. During clinical investigation, supportive and symptomatic treatments were necessary, and an abdominal radiography was performed revealing a large intestine filled with feces and large amounts of gas, in addition to free fluid in the cavity. After 3 days of treatment, the foal had not yet defecated, thus exploratory abdominal surgery was indicated, but the owners declined. Therefore, the foal was humanly euthanized. Post-mortem examination revealed complete absence of the pelvic flexure. Subsequent portions of the dorsal, transverse and small colons were intensely reduced. In addition, at the abdominal cavity there was 850 ml of yellowish translucent liquid. These findings are compatible with hydroperitoneum and type III atresia coli at the pelvic flexure, associated with underdevelopment of the dorsal, transverse and small colons.
Highlights
RESUMO: Um pônei mestiço de 48 horas de vida foi encaminhado ao hospital para avaliação por desconforto abdominal, diminuição do reflexo de sucção e prostração
Colic starting at birth or shortly thereafter can be caused by meconium impaction, uroperitoneum or fecoliths, and congenital disorders such as atresia coli, aganglionosis and hypoganglionosis (CHAFFIN et al, 1999; BOHANON, 2005)
Intestinal atresia should be suspected when there is no fecal material on the anus, with presence of clear mucus, absence of meconium staining following repeated enemas, progressive abdominal distention and pain on a neonate (YOUNG et al, 1992; VATISTAS et al, 1996; CHAFFIN et al, 1999; BIASUTTI et al, 2017)
