Summary

This study aimed to find out if two tests—EndoFLIP and antroduodenal manometry—could predict which patients with severe gastroparesis would benefit from a procedure called G-POEM. The plan was to measure stomach muscle activity and pressure before the procedure. However, the study was withdrawn before any participants were enrolled, so no results are available.
