[Percutaneous electrogastrography in the perioperative period in laparoscopic and classical cholecystectomy and in...

Percutaneous electrogastrography (EGG) is a non-invasive measuring method of gastric myoelectrical activity. We measured myoelectrical activity patients after laparoscopic cholecystectomy (16 patients), after laparotomic cholecystectomy (9 patients) and after gastric bandage (14 patients). We used a Microdigitrapper (Medtronic) and data were analysed with a spectral analysis and Fournier's transformation. We measured 24 hours and 5 hours before operation procedure and 24 and 48 hours after operation. After operative procedure we compared results with healthy voluntaries. Bradygastria was found in most frequent cases in early postoperative period. Physiologic conditions were renewed in laparoscopic operative procedure in first day, after laparotomic operation in second day after operation.
