CT quantitative assessment between pancreatectomy volume and blood glucose level

Abstract

Objective \nTo evaluate the relationship between postoperative residual pancreatic volume and change of blood glucose levels. \n \n \nMethod \nEighty-five cases of pancreatic benign and malignant tumor patients with preoperative and postoperative pancreatic CT images and clinical data were included retrospectively. Preoperative and postoperative pancreatic volume in benign patients and malignant patients were measured. Eight five patients were divided into 5 groups according to the resection volume ratio. Blood glucose levels were compared at different resection volume ratios. Correlation analysis of pancreatic resection volume ratio and blood glucose level were conducted in 39 benign patients and 46 malignant patients.ANOVA test, t test and Peason correlation coefficient were used. \n \n \nResult \nPostoperative benign and malignant group glucose level difference had statistical significance (P<0.05). Preoperative and postoperative malignant group of glucose level difference had statistical significance (P<0.05). Benign postoperative blood glucose between each groups was statistically significant (P<0.05); Malignant postoperative blood glucose between each groups was statistically significant (P<0.05); The volume ratio of benign and malignant tumor resection was positively correlated with postoperative blood glucose level (r values were 0.85 and 0.77, P<0.01). \n \n \nConclusions \nThere were statistically significant differences in blood glucose levels between pre-operation and post-operation of benign and malignant tumors. Postoperative blood glucose level was correlated with pancreatic resection volume, and postoperative blood glucose level was positively correlated with resection volume ratio. \n \n \nKey words: \nPancreatic neoplasms;\xa0Residual volume;\xa0Blood glucose;\xa0Tomography,X-ray computed;\xa0Diagnosis value
