Abstract
To investigate the change in serum visfatin level after laparoscopic Roux-en-Y gastric bypass surgery in patients with Type 2 diabetes mellitus (T2DM) and to explore the relationship between visfatin insulin resistance and diabetes. Thirty-three patients with Type 2 diabetes were studied before and after the gastric bypass surgery. The level of fasting serum visfatin was measured by enzyme-linked immunosorbent assay. Fasting plasma glucose (FPG), glycated hemoglobin (HbA1c) and fasting insulin (FINS) were measured before and after the gastric bypass surgery. Compared with before the operation, the indicators of HbA1c, FINS, and insulin resistance index (HOMA-IR) were decreased after the laparoscopic Roux-en-Y gastric bypass surgery. The body mass index (BMI) [(24.53 ± 0.62) kg/m² vs (26.71 ± 0.69) kg/m2] was decreased, with significant difference (P<0.001). The serum visfatin level [(9.79 ± 0.64) ng/mL] was significantly lower than before the operation [(38.24 ± 5.32) ng/mL], with significant difference (P<0.001). Serum level of visfatin is decreased in T2DM patients who undergo gastric bypass surgry, reflecting an improvement in insulin resistance and diabetes.
