Trial summary

Although intensive medical treatment of diabetes has clearly been demonstrated to be worthwhile, it has not been a total success in diabetes treatment for a variety of reasons including lack of response to medication. Diabetes has been well demonstrated as a co-morbidity illness of obesity patients. Read more about this study

About this study

Although intensive medical treatment of diabetes has clearly been demonstrated to be worthwhile, it has not been a total success in diabetes treatment for a variety of reasons including lack of response to medication. Diabetes has been well demonstrated as a co-morbidity illness of obesity patients. In observation, with exclusion stomach and duodenum of bariatric surgery (gastric bypass), most morbidly obese patients (about 80%) with diabetes had a significant improved of sugar control. Base of this observation, we will try to find out the role surgical intervention (gastric bypass \& sleeve gastrectomy) in obese-related diabetes.

Read the detailed description

In observation, with exclusion stomach and duodenum of bariatric surgery (gastric bypass), most morbidly obese patients (about 80%) with diabetes had a significant improved of sugar control. Base on this observation, we will try to find out the role surgical intervention (gastric bypass and sleeve gastrectomy) in obese-related diabetes. With restriction of stomach volume and with or without duodenal exclusion, this randomized trials will find out the role of duodenal exclusion and the role of Ghrenin in obese-related type II DM patients. The initial observation of previous morbidly obese patients with type II DM, the DM seems a chronic disease which could be treated or controlled by surgical intervention, that's what we try to know more.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing gastric bypass and sleeve gastrectomy in people with Type II Diabetes Mellitus, run by Min-Sheng General Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 Nov 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Lee WeiJei, M.D, Ph.D (886-3-3179599 ext. 1599, wjlee_obessurg_tw@yahoo.com.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure sugar levels, HbA1c levels, and medication needed. OGTT, MGTT. (time frame: 1st, 2nd, 3rd, 4th, 5th, 6th, 9th, 12th months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00540462, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
