The Research on Perioperative Blood Glucose and Insulin Levels of Patients with Single Insulinoma
Abstract Background The blood glucose level is an important biochemical parameter for evaluating the resection effectiveness of insulinomas. However, whether other biochemical parameters have better evaluating ability remains unclear. The current study aims to compare the evaluating capability of blood glucose and insulin levels at several aspects, such as the accuracy and response time. Methods Between September 2017 and July 2018, 21 insulinoma patients with single tumor who underwent surgical resection were enrolled. Peripheral venous blood samples were assayed for blood glucose and insulin levels on the day of surgery and at 30 minutes, 60 minutes, 1 day, and 7 days after surgery. The evaluating abilities of blood glucose and insulin levels for resection effectiveness were recorded and compared. Results The evaluating performance of the insulin level was better than that of the blood glucose level (100% for 21 patients vs 82.4% for 17 patients), as well as the response time ( p<0.0001). Furthermore, the insulin level was not effected by intravenous glucose infusion compared to the blood glucose level. Conclusions Comparing with blood glucose level, insulin level is a better parameter for evaluating resection effectiveness of insulinomas with faster response and regardless of perioperative intravenous glucose infusion.
