Brief Summary:
This study is to investigate the effect of gastrectomy on remission of type 2 diabetes in patients with gastric cancer and type 2 diabetes, to investigate the mechanism of blood glucose alteration and intestinal hormonal signaling by the reconstruction methods, and to evaluate the applicability and efficacy of Roux-en-Y gastrojejunostomy after gastrectomy in gastric cancer patients with diabetes.

Condition or disease Intervention/treatment Phase
Gastric Cancer Diabetes Procedure: Roux-en Y gastrojejunostomy Procedure: Gastroduodenostomy Not Applicable

Detailed Description:

Purpose:

  • To investigate the effect of gastrectomy on remission of type 2 diabetes in patients with gastric cancer and type 2 diabetes
  • To investigate the mechanism of blood glucose alteration and intestinal hormonal signaling by the reconstruction methods
  • To evaluate the applicability and efficacy of Roux-en-Y gastrojejunostomy after gastrectomy in gastric cancer patients with diabetes

Contents:

  • Evaluation of the status of diabetes in gastric cancer patients with DM after gastrectomy

    • Comparison of two reconstruction types after gastrectomy Bypass duodenum and upper jejunum: Roux-en-Y gastrojejunostomy Preservation of duodenal passage: Gastroduodenostomy
    • Analysis for biochemical markers reflecting diabetic status: fasting glucose, postprandial 2h glucose, HbA1c, C-peptide, lipid profile
  • Correlation of parameters associated with diabetes and GI hormones

    • Measurement of GI hormones which have an effect on glucose tolerance

      • Insulin, glucagon, IGF-1, GLP-1, Neuropeptide Y, Ghrelin, Leptin
    • Correlation of reconstruction methods, parameters of diabetes and GI hormone levels
    • Evaluation of mechanism of Roux-en-Y gastrojejunostomy on controlling diabetes
  • Evaluation of Feasibility of Roux-en-Y gastrojejunostomy in gastric cancer surgery in patients with DM

    • Degree of high blood glucose control, the amount of antidiabetic medication, costs for DM treatment, quality of life assessment
    • Analysis for the mechanism of gastrointestinal physiology to diabetes control

Arm Intervention/treatment
Active Comparator: Gastroduodenostomy
Arm 1: undergo gastroduodenostomy after distal gastrectomy for gastric cancer
Procedure: Gastroduodenostomy
After subtotal gastrectomy with lymph node dissection, the gastric remnant is anastomosed to duodenum 1st portion with circular or linear staplers and the artificial lesser curvature is repaired with linear stapler.
Experimental: Roux-en Y gastrojejunostomy
Arm 2: undergo Roux-en Y gastrojejunostomy after distal gastrectomy for gastric cancer
Procedure: Roux-en Y gastrojejunostomy
After subtotal gastrectomy with lymph node dissection, the jejunum is transected 25~30cm distal to the ligament of Treitz. Distal jejunum is drawn up and sutured to the gastric remnant and the proximal jejunum is anastomosed to the distal jejunum at 30~40cm from the new gastric-jejunal junction.



Primary Outcome Measures :
  1. Blood sugar stabilization after gastrectomy [ Time Frame: three months after surgery ]
    By comparing the difference between fasting blood sugar and postprandial blood glucose, blood sugar stabilization after gastrectomy will be maesured.
