Filter by:In this research study, biopsy samples will be collected to provide more insight into the underlying cause of the motility disorders, help direct further investigation into the cause of the underlying condition, provide future prognosis and predict response to gastric electrical stimulation (GES).
The purpose of this study is to determine the physiologic effects of temporary gastric electrical stimulation in subjects with severe gastroparesis.
The objective of this study is to determine if Gastric Electrical Stimulation may influence vagal outflow via vagal afferent fibers that terminate in the Central Nervous System.
Adult diabetic patients (ages 18-65) with gastric emptying scintigraphy-confirmed delayed gastric emptying will be recruited to participate in the study. Using double-blinded methodology, study participants will be randomly assigned to one of two treatment arms: promethazine 12.5 mg three times daily for 28 days or placebo three times daily for 28 days. The primary outcome will be the change in gastroparesis symptom severity, as measured by the Gastroparesis Cardinal Symptom Index (GCSI) at four weeks compared to baseline. Participants will be seen for a clinic evaluation at weeks 0, 2 and 4, during which symptom scores, adverse events and treatment compliance will be assessed. It is hypothesized promethazine treatment will be superior to placebo in improving symptoms of gastroparesis.
Delayed emptying of the gastric tube after esophagectomy is a frequent and durable problem. No treatment is currently available. It can be hypothesized that incomplete relaxation of the pyloric sphincter may be a significant contributing factor. Pneumatic dilatation may therefore be a potentially effective treatment.
Randomized controlled trial comparing haloperidol combined with conventional therapy and conventional therapy alone in patients with symptomatic gastroparesis.
A small gastric remnant after whipple resection improves gastric emptying and therefore prevents the development of delayed gastric emptying.
The incidence of gastroparesis has been increasing among Canadians. Symptoms of discomfort include early satiety, stomach pain, nausea and vomiting. In addition, because gastroparesis slows digestion, it can lead to malnutrition and make controlling blood sugar even more challenging for diabetics. Mild cases of gastroparesis can be helped with dietary and lifestyle modifications but treatments for more severe symptoms are limited. There are several drugs called pro-kinetics available in Canada though results vary among patients and these often cause significant side effects. Recently, a drug called Prucalopride was approved for use in Canada to treat constipation. It has pro-kinetic properties and has been shown to cause few side effects. The investigators propose to test prucalopride as a treatment for gastroparesis by recruiting 30 patients from the Calgary area who have gastroparesis. The investigators will test the effects of this treatment by alternating 28 days of active treatment with prucalopride with 28 days of treatment with a non active placebo adding a two week break in between treatments. The order of the treatment will be randomized and neither the patients nor the investigators will know whether they are receiving the active treatment or the placebo until the study has been completely finished. The investigators will measure the effects using questionnaires that assess patient symptoms such as nausea and pain as well as quality of life during two gastric emptying tests and throughout the treatment periods. The effectiveness of the active treatment will be evaluated by comparing the extent of the change in symptoms before and after treatments and the difference in gastric emptying times as compared to the placebo treatment. The investigators will also monitor and track all possible side effects that patients experience during the study. Study Hypotheses In patients with gastroparesis: 1. Prucalopride 4 mg daily improves meal-related symptoms compared to placebo as defined by the change in cumulative meal-related symptoms. (primary endpoint). 2. Prucalopride 4 mg daily accelerates gastric emptying rate compared to placebo. (secondary endpoint). 3. A correlation exists between the effect of prucalopride on gastric emptying rate and symptom improvement.

The purpose of this study is provide confirmation of the safety and efficacy of Metoclopramide Nasal Spray compared to placebo in reducing the symptoms of diabetic gastroparesis in adult women.
