ABSTRACT

This paper presents a large range of methods of human gastric pacing. Based on our own experience and literature authors discuss a variety of pacing models, current parameters and place of stimulation. We described a new method of intragastric stimulation as a method of treatment of postoperative, pharmacotherapy resistant gastroparesis. Five patients were included in to the study (3 male and 2 female). The current parameters were as follow square profile, amplitude 2V (2mA), frequency 6 ips.p.m., duration 3 hours. Two electrodes located on nasogastric catheter (external diameter 1.5 mm) were placed in antral region of the stomach and connected to the computer preprogrammed stimulator. Electrostimulation was accompanied by the continuous cutaneous EGG monitoring (Synectics Sweden). Excellent results were obtained in 3 patients (60%) with disappearance of symptoms, rumbling, normalization in gastric myoelectric rhythm (2-4 cpm > 85%) and with increase in amplitude (average 250%). In one patient with the gastrectasia, symptoms returned next day and stimulation had to be repeated for several days. In another one results were not satisfying. Authors conclude that gastric pacing has made tremendous progress fast developing method in last decade and in most patient is efficient for treatment postoperative gastroparesis.
