Clinical Trial Summary

This observational study was conducted in patients undergoing elective pancreaticoduodenectomy or distal pancreatectomy. It mainly answers the following two main questions: 1. What are the risk factors for clinically relevant postoperative pancreatic fistula in different pancreatic surgeries? 2. What is the correlation between perioperative blood and interstitial fluid glucose level and clinically relevant postoperative pancreatic fistula in different pancreatic surgeries? Participants were not required to perform additional research work other than the usual postoperative follow-up within 30 days after surgery. No control group was set in this study, and no additional clinical intervention was performed.


Description:

CR-POPF is a multi-center observational prospective cohort study. The research team focuses on whether perioperative abnormal hyperglycemia can independently predict the occurrence of CR-POPF. It is proposed to realize the dynamic monitoring of perioperative blood glucose level by non-invasive continuous glucose monitoring (CGM), and perioperative continuous glucose monitoring can reflect the overall blood glucose trend and mode, which is helpful to further explore the correlation between perioperative abnormal blood glucose level and CR-POPF. The investigators expect to enroll 600 patients. Based on our previous clinical experience, the incidence of postoperative pancreatic fistula is approximately 20%. We planned to enroll 600 patients during the 6-month enrollment period in three participating hospitals. The sample size would have a statistical power of 81.3% to detect an odds ratio (OR) greater than 1.34 or less than 0.75. Measurement data consistent with normal distribution were expressed as mean ± standard deviation, and t-test was used for comparison between groups. When not consistent with normal distribution, the measurement data were expressed as quartiles, and the Wilcoxon-Mann-Whitney rank sum test was used for comparison between groups. Count data were expressed as frequency and percentage. Pearson chi-square test or Fisher's exact test was used for comparison between groups. The binary logistic regression method was used to screen the risk factors and stratify the risk levels, P < 0.05 was considered statistically significant. A generalized estimation equation model was constructed to analyze the correlation between continuous blood glucose monitoring values and postoperative pancreatic fistula. The dependent variable in the model is whether there is pancreatic fistula after operation. The dependent variable in the model was the presence or absence of postoperative pancreatic fistula, and the main variable was the continuous glucose monitoring (CGM) value. The connection function uses the binomial distribution logit function. The multiple measurements of the same patient are set as the group-level variable, and the autocorrelation matrix is selected according to the Quasi-likelihood under Independence Model Criterion (QIC) value of the model. In addition to analysis using generalized estimating equations, continuous glucose monitoring data will be constructed, such as an analysis of the association between pancreatic fistula and the area under the curve for measurement and time beyond normal glucose values. The statistical software was STATA ( version 15.0; stata Corp., Texas, USA ) and R 3.6.1 software ( R Foundation for Statistical Computing, Vienna, Austria ), bilateral P < 0.05 was considered statistically significant.

Outcome

Type Measure Description Time frame Safety issue
Primary Clinically relevant postoperative pancreatic fistula Clinically relevant postoperative pancreatic fistula is now redefined as a drain output of any measurable volume of fluid with an amylase level >3 times the upper limit of institutional normal serum amylase activity, associated with a clinically relevant development/condition related directly to the postoperative pancreatic fistula. 30 days after surgery
Secondary Bile leakage Bile leakage was defined as bilirubin concentration in the drain fluid at least 3 times the serum bilirubin concentration on or after postoperative day 3 or as the need for radiologic or operative intervention resulting from biliary collections or bile peritonitis. 30 days after surgery
Secondary Chyle leak Chyle leak was defined as output of milky-colored fluid from a drain, drain site, or wound on or after postoperative day 3, with a triglyceride content greater than or equal to 110 mg/dL (1.2 mmol/L). 30 days after surgery
Secondary Postpancreatectomy hemorrhage Postpancreatectomy hemorrhage is defined by 3 parameters: onset, location, and severity. The onset is either early (24 hours after the end of the index operation) or late (24 hours). The location is either intraluminal or extraluminal. The severity of bleeding may be either mild or severe. 30 days after surgery
Secondary Abdominal infection Abdominal infection was defined as a patient with symptoms such as shivering, high fever, abdominal distension, intestinal paralysis and other symptoms 3 or more days after surgery lasting for more than 24 hours.Laboratory examination results showed significant increases in white blood cell count, procalcitonin, and hypersensitive C-reactive protein, and imaging examination showed accumulation of fluid in the abdominal cavity. The diagnosis can be confirmed by the detection of bacteria or fungi in abdominal drainage or paracentesis fluid. 30 days after surgery
Secondary Delayed gastric emptying Delayed gastric emptying was defined as indwelling gastric tube for more than 3 days after surgery, or re-indwelling gastric tube after 3 days due to vomiting or abdominal distension, or still unable to tolerate solid food 7 days after surgery under the premise of unobstructed gastrointestinal or duodenojejunal anastomosis and no obstruction of the small intestine. 30 days after surgery
