The 20-min rate of gastric emptying of a noncaloric solution and c-fos expression detected by immunohistochemistry in the brain were monitored 3 h after abdominal surgery performed under 10-min enflurane anesthesia in rats. Abdominal surgery (laparotomy and 1-min manipulation of the cecum) decreased gastric emptying from 60.8 +/- 3.4 to 25.9 +/- 3.4%. Capsaicin applied to the celiac/superior mesenteric ganglia 2 wk before the experiment reduced the delay in gastric emptying induced by abdominal surgery (46.3 +/- 3.4%), whereas perivagal capsaicin application had no effect (23.6 +/- 7.9%). The corticotropin-releasing factor (CRF) antagonist [D-Phe12, Nle21,38,C alpha MeLeu37]CRF-(12--41) injected intracisternally (10-20 micrograms) prevented postoperative gastroparesis induced by surgery, while having no effect on basal gastric emptying. Abdominal surgery increased the number of Fos-positive cells in brain nuclei regulating autonomic outflow: the nucleus of the solitary tract, locus ceruleus, paraventricular nucleus, and supraoptic nucleus of the hypothalamus. These data indicate that capsaicin-sensitive splanchnic afferent fibers and activation of CRF receptors in the brain are part of the neuronal circuitry mediating gastric stasis 3 h after abdominal surgery.
