[Motor-evacuation disorders of the digestive tract in the early period after stomach surgery. 3. Motor-evacuation disorders of the large intestine].

The balloonographic method was used for studying the motor function of the sigmoid in 15 healthy volunteers, 15 patients with peptic ulcer before operation and in 25 patients at early terms after truncal vagotomy or resection of the stomach. During the first 2-3 days independent of the type of surgical intervention and of the degree of extra-organic denervation of the digestive tract, the motor activity of the sigmoid has the autonomic regimen of regulation, pathognomic structure of the motor cycle and is characterized by a sufficiently high contractile activity at the expense of frequent and regular generation of the migrating motor complexes. The restoration of the motor function is completed by the 5th-6th day. The states of normo-, hypo- and adynamia of the sigmoid were established on the basis of the contraction activity coefficient. The functional motor-evacuatory disorders of the intestine of the middle and grave degree are always accompanied by hypodynamia and transitory adynamia of the sigmoid.
