Anatomic-radiographic aspects and gastrointestinal transit time in boa constrictor amarali stull, 1932 (Squamata, Boidae)

Abstract

The goal of this study was to describe the gastrointestinal transit technique in the Boa constrictor amarali. For that purpose, we obtained simple radiographic images of seven serpents, subsequently administering a 25mL/kg dose of barium sulfate and establishing a radiographic sequence at the following times: 5 minutes; 1, 2, 3, 6, 9, 24, 48, 72 and 96 hours, extending to 120 and 126 hours for one animal. The mean esophageal transit was 26.71±19.48 hours; the mean gastric filling time was 28.57±27.22 minutes and the emptying time was 60±12 hours; the mean filling time of the contrast medium in the small intestine was 3±2.16 hours and the emptying time was 97±15.65 hours. We also obtained the mean filling time of the large intestine, which was 40±11.31 hours. We found that the mean passage time of the contrast medium through the cranial gastrointestinal tract - until the complete elimination of barium sulfate from the small intestine -was 97±15.65 hours. In addition to determining the gastrointestinal transit time, the technique used allowed for the morphological identification of the alimentary canal.

“…In the present study, the right dorsolateral approach allowed better visualization of the liver. An anatomic constrictor amarali verified that the liver was placed in the right antimere (Milken et al, 2020).…”

“…In the present study, the right dorsolateral approach allowed better visualization of the liver. An anatomic study in Python observed that the liver is positioned on the right side of the spine (Hopkinson & Pancoast, 1837), and another in B. constrictor amarali verified that the liver was placed in the right antimere (Milken et al., 2020).…”
