Value of Oakland score system combined with coagulation function index in predicting bleeding risk of lower digestive tract after endoscopic resection of colon polyps
Objective To assess the predictive capability of the Oakland scoring system combined with coagulation function indicators for lower gastrointestinal bleeding following endoscopic resection of colon polyps.Methods A total of 337 patients who underwent endoscopic resection of colon polyps at our hospital from January 2020 to May 2023 were included.Patients were categorized into two groups:non-bleeding(n=308)and bleeding(n=29)based on the occurrence of lower gastrointestinal bleeding occurred within 72 hours post-surgery.Compare the basic clinical data of two groups of patients,including fibrinogen(FIB),platelet count(PLT),Prothrombin time(PT),D-dimer(D-D)and Oakland score,and analyze the predictive value of Oakland score and coagulation indicators on the risk of lower gastrointestinal bleeding after polypectomy.Results Compared with the non bleeding group,the Oakland score and D-D levels in the bleeding group increased,PT time prolonged,FIB and PLT levels decreased,and there were statistically significant differences between the groups(t=13.601,4.945,9.329,2.141,2.159,P<0.05).Multivariate logistic regression analysis found that hypertension,polyp diameter,whether the polyp has a pedicle,physician skills,Oakland score,FIB,PLT,PT,and D-D were risk factors for postoperative lower gastrointestinal bleeding in patients.Oakland score,FIB,PLT,PT,D-D were correlated with postoperative lower gastrointestinal bleeding,with correlation coefficients of 0.690,-0.618,-0.682,0.461,and 0.357,respectively.The combined prediction of Oakland score,FIB,PLT,PT,and D-D has the largest area under the ROC curve for postoperative lower gastrointestinal bleeding in patients,which is 0.853.Conclusion Coagulation indicators and the Oakland score are closely associated with postoperative bleeding in patients with colon polyps.Combining the Oakland score with PLT,FIB,PT and D-D holds promise in predicting lower gastrointestinal bleeding after polypectomy.Tailored intervention strategies can be devised for patients at high risk of bleeding to improve prognosis.
