Abstract

Percutaneous electrogastrography (EGG) is a method which makes non-invasive follow-up of the myoelectric gastric activity possible. The authors present the results of assessment of the myoelectric gastric activity during the perioperative period in patients undergoing, at the First Surgical Clinic General Faculty Hospital, laparoscopic non-adjustable gastric banding. The data were recorded using a Microdigittrapper and evaluated using spectral analysis and Fourier's transformation. The authors mention also briefly conditions which must be met to ensure the study, and the physiological and pathophysiological background of the method. In 14 patients the ECG record was made 24 hours prior to surgery and then 5 hours, 24 and 48 hours after surgery on fasting and after a fluid bolus. The assembled results of the dynamics of perioperative changes on the EGG were compared with results obtained in a group of healthy volunteers. The most frequent finding during the early postoperative period was bradygastria, the return to preoperative values occurred on average 48 hours after surgery. Percutaneous electrogastrography is a non-invasive method which can provide the surgeon during the early postoperative period with information on myoelectric gastric activity.
