[Motor evacuatory disorders of the digestive tract in the early periods after stomach operations (1. Motor evacuatory disorders of the stomach)].

The method of telemetry was used for studying the motor function of the stomach in 60 patients with ulcer disease before operation and in 48 patients at early terms after truncal vagotomy or resection of the stomach. An analysis of 318 cases of similar operations on the stomach was also made. The states of normo-, hypo- and adynamia were documented. A pronounced inhibition of motility of the stomach and its stump were noted during 14 and more days after vagotomy and resection. Under conditions of hypo- and adynamia the evacuatory function was maintained by the positive gastrointestinal gradient of the basal pressure and the peristaltic "pump" effect of the small intestine. The early light motor evacuatory disorders are always of the functional character and disappear by the 5th day after operation. The evacuatory disorders of the moderate and grave degree were functional in 7 from 9 patients after vagotomy and in 9 from 17 patients after resection of the stomach.
