Comparison of the Efficacy and Satisfaction of Blood Glucose Management Between Continuous Glucose Monitoring Versus Traditional Self-blood Glucose Measurement in Diabetic Patients After Pancreatectomy

Study Overview
=================
Brief Summary
-----------------
This study aims to compare the efficacy and satisfaction of blood glucose management between continuous glucose monitoring versus traditional self blood glucose measurement in diabetic patients after pancreatectomy.

Detailed Description
-----------------
Patients will be enrolled after the 75g oral glucose tolerance test performed 7 days after pancreatectomy. Patients will be divided into two groups by randomization (continuous glucose measurement method vs. traditional self blood glucose measurement method), and 3months after surgery, HbA1c, hypoglycemic events, and satisfaction would be compared.
