Gastric pacing for diabetic gastroparesis--does it work?

: The management of diabetic gastroparesis resistant to medical therapy is very difficult Gastric electrical stimulation (GES) is a relatively new therapeutic modality which has shown some promise in international trials. It has seen use in four patients in Ireland. Our aim was to determine if GES improved patients' outcomes in terms of duration and cost of inpatient stay and glycaemic control. We reviewed the patients' case notes and calculated the number of days spent as an inpatient with symptomatic gastroparesis pre and post pacemaker, the total cost of these admissions, and patients' average HbA1c pre and post GES. Mean length of stay in the year pre GES was 81.75 days and 62.25 days in the year post GES (p=0.89). There was also no improvement in glycaemic control following GES. GES has been ineffective in improving length of inpatient stay and glycaemic control in our small patient cohort.
