This Article in December issue of Gastroenterology summarizes the findings from the Gastroparesis Clinical Research Consortium (7 tertiary care centers). Out of 262 patients- only 28% had a reduction in symptoms that was significant.
They also tabulated factors that are associated with reduction in symptoms – male sex, older age, infectious prodrome, antidepressant use, and 4-hr retention greater than 20%.
This is bad news for those with gastroparesis. Most importantly there was no difference in those with and without diabetes.
Most notably there is no post-treatment gastric emptying, which would be interesting to see who actually improved, and who just “felt” better, and whether there is a correlation between these.
