About

Gastroparesis is a common complication of prolonged diabetes mellitus, both with Type 1 and Type 2 forms. Treatment of diabetic gastroparesis ranges from changing dietary habits to medications and invasive procedures, all of which offer only partial and transient relief, with some options having potentially harmful effects. Acupuncture is an ancient treatment which has been found to be beneficial for many ailments, including those involving the gastrointestinal tract. We propose to evaluate whether acupuncture is an effective and safe treatment for diabetic gastroparesis using a randomized, double-blind, placebo/sham-controlled crossover trial. Because symptoms of gastroparesis do not correlate well with objective tests of gastric emptying (i.e., scintigraphy or 13C breath tests), our primary outcome value will be the Gastroparesis Cardinal Symptom Index (GCSI), a reliable and validated instrument for quantifying symptoms in these patients. As a secondary outcome we will measure gastric emptying using a C13-acetate breath test, as well as the SF-12 Short Form Health Survey. Blinding of the participants will be evaluated using a Validation of Blinding Questionnaire at the end of the treatment period.

Diabetic patients suffering from moderate gastroparesis (total GCSI score > 2.50) who fulfill the inclusion criteria (and none of the exclusion criteria) will be eligible to participate in the study. On induction, participants will fill out the GCSI questionnaire and SF-36 survey, and will undergo a C13-acetate breath test. They will then be randomly assigned to either true acupuncture treatment or placebo/sham acupuncture treatment. Each participant will undergo 8 treatments twice-weekly, for a period of 4 weeks. At the end of the eighth treatment session, each participant will again fill out a GCSI questionnaire and SF-12 form, as well as repeating the C13-acetate breath. Following a 4-week washout period, patients will be crossed over to either placebo/sham or true acupuncture treatment, again 8 twice-weekly treatments, for a period of 4 weeks. At the end of the second treatment regimen all participants will again fill out a GCSI questionnaire and SF-12 form, and undergo a C13-acetate breath test. At the end of the second treatment regimen participants will again fill out a Validation of Blinding Questionnaire.
