Transcutaneous electrogastrography
Davidová, Lenka ; Závodná, Eva (referee) ; Nováková, Zuzana (advisor)
The aim of this thesis is to introduce the physiology and pathophysiology of the gastrointestinal tract, with functional parameters and appropriate diagnostics. The thesis also deals with transcutaneous electrogastrography devices and presents a suggestion of a measurement protocol which would involve a group of volunteers in fasting and postprandial states. The theoretical part describes the function of the gastrointestinal tract, detailing the analysis of gastric myoelectric activity and gastric motility. It also outlines technical and formal aspects of the parameters, artefacts and subsequent data analysis. In the practical part, a program is designed and implemented in the Matlab computing environment for the analysis of EGG recordings. Furthermore, differences between parameters in fasting and postprandial states are evaluated.

Percutanous electrogastrography, principle and posibilities of clinical application in abdominal surgery
Fraško, Roman ; Krška, Zdeněk (advisor) ; Maršálek, Petr (referee) ; Szárszoi, Ondrej (referee)
Author of this dissertation presentation discuss in the begining definition and historical consequences of origin and consecutive evolution of the method of percutaneous electrogastrography. Intimately is described physiology, anatomy, embryology and function of gastrointestinal tract with special interest on construction and function of the stomach. Next to this author analyses current knowledge about location and function of the gastric pace setter. The technique of used perctutaneous electrogastrography equipmentt is described. In the second part results of original studies monitoring restoration of peristalsis in perioperative period at patients after open and laparoscopic cholecystectomy and laparoscopic non-adjustable gastric banding are discussed. Furthermore results of EGG measurement of patients with mechanic, vascular and paralytic intestinal obstruction are presented in correlation with plasma levels of interleukin 1β, interleukin-6, procalcitonin and C-reactive protein. Key words: Percutanous electrogastrography, laparoscopic cholecystectomy, laparoscopic gastric bandage, inflammatory mediators, intestinal obstruction.
