Gastric evacuation and propulsive intestinal motility in acute afferent loop syndrome in the rat.
The acute afferent loop syndrome, i.e. occlusion of the afferent loop after partial gastrectomy by the Billroth II method, was produced in the rat. In a primary session a gastrojejunostomy with division of the pylorus was performed. 2-3 months later the afferent loop was ligated. The gastric evacuation and the propulsive motility of the intestine were studied quantitatively, using an inert radioisotope. Both the gastric evacuation and the propulsive intestinal motility were considerably delayed in ALS, both in relation to the laparotomized controls and in relation to previous findings in mechanical intestinal obstruction and paralytic ileus due to retroperitoneal irritation or bacterial peritonitis.
