Gastric electrical Stimulation (GES) is an accepted therapy for drug refractory gastroparesis, but its effect on gastric emptying is controversial. Patients: To examine the effect of GES on GET we examined 140 consecutive patients undergoing temporary endoscopic GES as previously described (GIE 2005: 61:455–461). Pts were 29 m, 14 f, mean age 41 years with diagnosis (DX): 44 diabetes (DM), 14 post‐surgical (PS) and 82 idiopathic (ID). Methods: Symptom Assessment, Gastric emptying and EGG were evaluated at baseline and after temporary endoscopic GES (mean 3 day of therapy). Patients at baseline were stratified into 3 groups based on GET: Delayed, Normal and Rapid, as previously described (AGC 2001: 95:1456–1461). Symptoms (SX) of nausea (N), vomiting (V), and total SX (TSS), and GET were compared by paired t‐tests and reported as mean values. Results: All patients had Symptoms improvement, irrespective of their DX or baseline GET: (N: 3.5 baseline to 0.9 after; V: 2.5–0.6; TSS: 15.2–5.1 for all patients with uniform changes in subgroups. There were no significant changes in GET for the whole patient group. However, when stratified by baseline GET: the delayed group accelerated (and the rapid group slowed (see table). Conclusion: Temporary GES performed on patients with the SX of gastroparesis shows an immediate symptom improvement, which is independent of baseline GET. The effect of temporary GES on gastric emptying is dependent on baseline emptying, with improvements seen in both delayed and rapid gastric emptying sub‐groups. Conclusions about the effect of electrical stimulation on gastric emptying need stratification for baseline gastric emptying.Group B GET 1 B GET 2 B GET 4 Aft GET 1 Aft GET 2 Aft GET 4All ( n = 140) 66.6 43.9 20.7 66.3 44.1 20.6 Delay ( n = 78) 77.3 57.3 31.6 57.1 41.1 21.3 P value 0.04 0.08 0.18 Rapid ( n = 15) 27.3 9.45 2.7 30.5 14.3 3.1 P value – – – 0.08 0.04 0.4
