Telemetric estimation of the descending colon pressure changes on dogs before and after total and selective vagotomy.

This experimental study describes the pressure changes of the descending colon before and after total and selective vagotomy combined with Finney's pyloroplasty as estimated by telemetry. The results obtained from the study of 20 dogs show that the motility of the descending colon is extremely reduced after total vagotomy with no change after selective vagotomy.
