Outcome and follow-up
Two weeks post-surgery, the patient exhibited elevated blood glucose levels. Fasting blood glucose measured 274.32 mg/dL, and 2-hour postprandial blood glucose was 334.26 mg/dL(see Table 2), indicating secondary diabetes mellitus. Insulin therapy was initiated for glycemic control. Following hospital discharge, the patient used insulin sporadically, without experiencing hypoglycemia. Six months post-surgery, fasting blood glucose was 284.58 mg/dL, and glycosylated hemoglobin was 12.5%. The patient received instructions to use insulin consistently. Over the subsequent four years, no hypoglycemic episodes occurred, and glycemic control remained reasonable.
