Cooperative Group for Clinical Research in G-POEM (POP), Jiangsu, China

Diabetic gastroparesis, postsurgical gastroparesis, idiopathic gastroparesis and primary pyloric stenosis are debilitating gastrointestinal motility disorder. However, there is limited medical therapeutic options for these diseases. Gastric peroral endoscopic pyloromyotomy (G-POEM) is an emerging novel endoscopic technique which is reported as a minimally invasive therapy. But so far, the efficacy and safety of G-POEM on these diseases are rarely explored. So, there is a cooperative group composed of five clinical centers for clinical research in G-POEM.

Participants are randomly devided into 'G-POEM group' and 'Esomeprazole+Mosapride group'. In G-POEM group, each participant receives G-POEM treatment. In Esomeprazole+Mosapride group, each participant receives Nexium 40mg bid + Mosapride Citrate Tablets 5mg tid. The whole outcome measure time fram is up to two years. Outcome evaluations include: gastric emptying imaging, gastric antrum volume, gastric emptying time, gastroparesis cardinal symptoms index and gastroesophageal reflux disease questionnaire. All the outcomes are assessed at different time points (from baseline to 6 months, 12months and 24months).
