Abstract:
Objective To investigate the effect of gastrointestinal Roux-en-Y gastric bypass surgery on blood sugar and insulin function of patients with type-2 diabetes mellitus.Methods Twenty-seven cases of gastric cancer patients with type-2 diabetes and undergone Roux-en-Y bypass the gastrointestinal treatment in the centre hospital of Cangzhou were selected as our subject.Body mass index (BMI),Glycosylated hemoglobin (HBA1c),Fasting and glucose (FPG),fasting insulin (FINS),Fasting C-peptide (FCP) levels were measured.Glucose (2 hPG),insulin (2 hINS) and C-peptide (2 hCP) levels were detected after 2 h for oral use 75 g glucose.Homeostasis model was applied to assess insulin resistance index (HOMA-IR).Results No significant change was seen in terms of BMI between before and after surgery.Compared to before surgery,the levels of FPG((7.58 ±0.84) mmol/L),2 hPG((10.43 ± 1.88) mmol/L),HbA1c((7.56 ± 1.15)％) and HOMA-IR(4.55 ±0.76) were lower in patients at 3 months after surgery ((9.93 ± 1.57) mtmol/L,(13.89± 2.13) mtmol/L,(9.88 ± 1.66) ％,(4.55 ± 0.76),respectively,P ＜ 0.05 or P ＜ 0.01).FPG ((6.56± 0.80) mmol/L),2 hPG ((8.57 ± 1.32) mmol/L),HbA1 c ((6.37 ± 1.24) ％),HOMA-IR (4.03 ± 0.45)of patients after 6 months were lower than that of before surgery and 3 months after surgery (P ＜ 0.05 or P＜0.01).However,the levels of FINS ((13.67 ± 1.96) mU/L),FCP((2.62 ±0.87) μg/L),2 hINS((49.91± 5.14) mU/L) and 2 hCP ((6.28 ± 1.65) μg/L) were higher in patients with 3 months after surgery compared to that of before surgery ((11.08 ± 1.69) mU/L,(1.78 ± 0.61) μg/L,(36.05 ± 4.03) mU/L,(4.28 ± 1.48) μg/L,P ＜ 0.01).Meanwhile those indices after 6 months (FINS:(15.88 ± 2.05) mU/L,FCP:(3.30 ±0.68) μg/L,2 hINS:(67.40 ±5.68) mU/L,2 hCP:(9.39 ± 1.52) μg/L) were higher than that of before surgery and 3 months after surgery(P ＜ 0.01).Conclusion Roux-en-Y gastrointestinal bypass can effectively reduce blood sugar level and improve the situation of Pancreatic Beta-cell function of gastric cancer patients with type-2 diabetes.
