This is a description of the radiographic appearance of the normal gastrointestinal tract of neonatal crias with survey and contrast radiography, including transit times for the various segments of the gastrointestinal tract. Radiographs of the abdomen of six healthy neonatal llama crias positioned in right lateral and dorsal recombency were obtained initially then at various intervals post barium administration. Portions of the gastrointestinal tract that could be identified included the stomach with first, second and third compartments, the duodenal ampulla, small intestine, proximal loop of the ascending colon, spiral colon and descending colon. Barium given by orogastric intubation rapidly entered all three compartments of the stomach and the proximal small intestine. Overall the transit time through the intestinal tract of the crias was longer than expected with no emptying of the ascending colon and beyond though studies were carried to 48-72 hours. Recommendations are made for frequency of radiographs.
这是一篇关于新生小羊驼胃肠道正常影像学表现的描述，采用了透视和造影X线摄影，包括胃肠道各段的通过时间。最初对6只健康新生小羊驼右侧卧位和背卧位时的腹部进行X线摄影，然后在给予钡剂后的不同时间间隔进行拍摄。可识别的胃肠道部分包括具有第一、第二和第三胃室的胃、十二指肠壶腹、小肠、升结肠近端袢、螺旋结肠和降结肠。经口胃插管给予的钡剂迅速进入胃的所有三个胃室和近端小肠。总体而言，小羊驼肠道的通过时间比预期的要长，尽管研究持续到48 - 72小时，但升结肠及更远端部位未排空。文中还给出了X线摄影频率的建议。
