Prospective Observatonal Study for Effect of Duodenojejunal Bypass and Gastric Bypass on T2DM Patients (T2DM)

This study has been completed.
Information provided by (Responsible Party):
Inha University Hospital Identifier:
First received: November 24, 2012

Last verified: November 2012

Surgical treatment for type 2 diabetes has been taken note especially in less obese or non obese patients. In Asian, the nuber of less obses or non obese patients with T2DM is greater than that of the obese.

We are trying to do a prospective observational study for the evaluation of the effect of duidenojejunal bypass and gastric bypass on the glycemoc control in those patients.

The selection criteria are type 2 diabetess, 20-60 years old, BMI 23-34 or 21-22 with viceral obesity, insulin use less than 10 years and the patients understanding the hypothesis of this study, risks, expecting effects and agreeing this study.

We are checking oral GTT, insulin level, C-peptide level, HbA1C, etc. with some anthropometric measurs preoperatively, postoperatively, at 3 month and 12 month.

We will compare the clinical factors at each time.

Condition Intervention
Non Insulin Dependent Diabetes Mellitus Procedure: laparoscopic roux en Y gastric bypass / open duodenojejunal bypass

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Metabolic Surgery for Type 2 Diabetes

Further study details as provided by Inha University Hospital:

Primary Outcome Measures:
  • Hemoglobin A1C [ Time Frame: preoperatively, at 3month, at 12 month ]
    change of the level

Secondary Outcome Measures:
  • oral glucose tolerance test [ Time Frame: preopertively, postoperatively, at 3 month, at 12 month ]
    changes of the level at each time

Other Outcome Measures:
  • insulin level [ Time Frame: preoperatively, postoperatively, at 3 month, at 12 month ]
    change the levels
