Electrogastroenterography signs of impairedmotor-evacuation function of the gastrointestinal tractin the early postgastrectomy period

Objective. To study elektroenterografic signs of violations of motor-evacuation function of the gastrointestinal tract in the early postgastrectomy period, depending on the type of neuraxial component postoperative analgesia.Materials and methods. The study involved 237 patients who underwent resection of the stomach in various modifications. For the prevention of post-resection complications in 175 (73,8 %) patients with neuraxial analgesia component of the surgical intervention and postoperative analgesia was performed using standard methods of continuous infusion of 0,2 % ropivacaine at a rate of 8-12 ml / h into the epidural space at the level Th7-Th8. In 62 (26,2 %) patients neuraxial component is ensured by the developed technique retroplevral constant infusion of 0,2 % ropivacaine solution for the purpose of segmental blockade of the left thoracic sympathetic trunk.Assessment of changes in the small intestine of electrical activity in the surveyed groups in the early postoperative period was performed using peripheral electrogastroenterography by «Gastroskan».Results and discussion. Revealed loss of rhythmic contractions in the stomach in the 1-2 th day, the duodenum - in the first 5 days, which led to a reduction coefficient of rhythm of upper gastrointestinal tract. For the early postgastrectomy period characterized by discoordination gastrointestinal motility all associated with infringement generation interdigestive myoelectric complex.Conclusions. The results of the peripheral electrogastroenterography show a significant decline in the relative electrical activity of the stomach, duodenum and jejunum from 1-x postgastrectomy period, while this pattern is maintained without the dynamics throughout the early postgastrectomy period. The study noted loss of rhythmic contractions in the stomach in the 1-2 th day and duodenum - the first 5 days, which led to a reduction coefficient of rhythm upper gastrointestinal tract. Postgastrectomy period characterized by discoordination gastrointestinal motility all associated with infringement generation interdigestive myoelectric complex. Peripheral electrogastroenterography is accessible, low-cost and non- invasive diagnostic technology to identify and predict the motor-evacuation disorders of the gastrointestinal tract function in early postgastrectomy period.
