Gastric Electrical Stimulation (GES) and Pyloroplasty for the Treatment of Gastroparesis

United States44 participantsStarted 2017-01-10

Plain-language summary

Gastroparesis (GP) is describing a condition when stomach does not empty as fast as it should. This fact creates the situation, when food stays in the stomach for a long time and it causes symptoms of nausea, vomiting, loss of appetite, bloating, inability to finish normal size meal and abdominal pain. There are not many drugs available to treat this condition and majority of gastroparetic patients are not responding well to them after they are on it for some time. Many investigators are able to implant Gastric Stimulator System (GES) under FDA approved status of Humanitarian Device Exemption (HDE) definition. In the last few years it became possible to add another surgical procedure, which is called pyloroplasty (making bigger opening on the end of stomach), may help even more as it is also increasing the rate of the emptying of the stomach. Therefore this study is proposing to evaluate if GES in combination with pyloroplasty is much better than pyloroplasty alone. For this reason, two of these procedures will be introduced surgically at the same time, but GES devices will not be turn ON in half of these participants for 3 months. After that time all subjects will have their devices turned ON. All subjects will be asked to evaluate their symptoms of gastroparesis and their quality of life during clinical visits, and investigators will conduct pathological analyses of tissue obtained during surgery.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
