The aim of this study was to investigate abomaso-duodenal digesta transport during abomasal displacement and after surgical correction of the abomasum, using intra-abomasal bile acid concentration. In healthy cows, bile acids were found in the abomasum, indicative of duodeno-abomasal reflux being a physiological event. In cows with left abomasal displacement (LDA), right abomasal displacement (RDA) and abomasal volvolus (AV), abomasal bile acid concentration was significantly higher than in healthy control cows. This was found to be true during surgery, on the first day as well as on the third day after surgery. Abomasal bile acid concentration was significantly different between LDA, RDA and AV, with LDA, RDA and AV showing lowest, intermediate and highest values respectively. In those with LDA and RDA, abomasal bile acid concentration significantly increased from surgery to first day after surgery, and decreased from first to third day after surgery. In AV cows, however, bile acid concentration declined constantly from surgery to third day after surgery. These findings indicate pathological duodeno-abomasal reflux during abomasal displacement and after surgical correction of the abomasum. Reflux seems to differ between forms of displacement (LDA < RDA < AV) and during recovery. Pathological duodeno-abomasal reflux is discussed as a consequence of functional and/or mechanical impediments on abomaso-duodenal digesta transport during abomasal displacement and after surgical correction of the abomasum.
本研究的目的是利用皱胃内胆汁酸浓度，调查皱胃移位期间及皱胃手术矫正后的皱胃 - 十二指肠消化物运输情况。在健康奶牛中，皱胃内发现了胆汁酸，这表明十二指肠 - 皱胃反流是一种生理现象。在患有左方皱胃变位（LDA）、右方皱胃变位（RDA）和皱胃扭转（AV）的奶牛中，皱胃胆汁酸浓度显著高于健康对照奶牛。在手术期间、术后第一天以及术后第三天均发现如此。LDA、RDA和AV之间的皱胃胆汁酸浓度存在显著差异，LDA、RDA和AV分别呈现最低、中等和最高值。在患有LDA和RDA的奶牛中，皱胃胆汁酸浓度从手术到术后第一天显著升高，从术后第一天到第三天则下降。然而，在AV奶牛中，胆汁酸浓度从手术到术后第三天持续下降。这些发现表明，在皱胃移位期间及皱胃手术矫正后存在病理性十二指肠 - 皱胃反流。反流似乎在移位形式（LDA < RDA < AV）之间以及恢复过程中有所不同。病理性十二指肠 - 皱胃反流被认为是皱胃移位期间及皱胃手术矫正后皱胃 - 十二指肠消化物运输功能和/或机械障碍的结果。
