Abstract
PURPOSE: Recent studies have highlighted the importance of understanding trends in blood glucose levels. We examined the differences in blood glucose fluctuations according to the reconstruction method used after distal gastrectomy (DG) in patients with non-diabetic gastric cancer (GC). METHODS: Sixty-one patients who underwent DG followed by either Billroth 1 (B1) or Roux-en-Y (R-Y) reconstruction were enrolled in this study. We used flash continuous glucose monitoring (CGM), a new technique for assessing glycemic control, to document the post-gastrectomy glycemic profile. Immediately before discharge, a CGM sensor was placed subcutaneously to evaluate blood glucose trends for 2 weeks. RESULTS: The coefficient of variation of glucose levels was significantly higher in the Roux-en-Y (R-Y) group than in the Billroth I (B-I) group (p = 0.0260). The time below range (TBR, glucose levels of < 70 mg/dL) was also significantly higher in the R-Y group (p = 0.0115). Logistic regression analysis revealed that preoperative casual glucose levels of < 100 mg/dL and R-Y reconstruction were independently correlated with risk factors for a postoperative nocturnal TBR of > 30% (p = 0.006 and 0.042, respectively). CONCLUSION: Our findings provide new insights into the post-DG reconstruction method selected for patients with non-diabetic gastric cancer by assessing postoperative blood glucose fluctuations using flash CGM.
