Risk factors of delayed hemorrhage after endoscopic resection of colorectal polyps

Objective To study the risk factors of delayed hemorrhage after endoscopic resection of colorectal polyps.Methods 3203 patients with the incidence of delayed hemorrhage after resection of colorectal polyps were analyzed.The effects of gender,age,polyp location,polyp pathological type,intraoperative bleeding,coronary heart disease,hypertension and diabetes mellitus on delayed hemorrhage after endoscopic resection of colorectal polyps were analyzed.Results 78 cases of delayed hemorrhage after endoscopic resection of colorectal polyps were found,accounting for 2.44%.Among them,55 cases occurred within 24 h to 4 d after endoscopic treatment,and the latest one occurred 14 d after the surgery.There were 48 males and 30 females with delayed hemorrhage;46 cases were younger than 60 years old and 32 cases were older than 60 years old;polyps were located in rectum in 24 cases,left colon in 22 cases and right colon in 32 cases;there were 9 cases of proliferative polyps,13 cases of inflammatory polyps and 56 cases of adenomatous polyps;intraoperative bleeding occurred in 23 cases;4 cases of coronary heart disease;22 cases of hypertension;5 cases of diabetes mellitus.There were 2037 males and 1088 females without delayed hemorrhage;1799 cases were younger than 60 years old and 1326 cases were older than 60 years old;the polyps were located in rectum in 627 cases,left colon in 1447 cases and right colon in 1051 cases;there were 325 cases of proliferative polyps,596 cases of inflammatory polyps and 2204 cases of adenomatous polyps;intraoperative bleeding occurred in 164 cases;110 cases of coronary heart disease;245 cases of hypertension;199 cases of diabetes mellitus.The polyp location,intraoperative bleeding and hypertension were compared between patients with delayed bleeding and patients without delayed bleeding,and the differences were statistically significant(P<0.05).Conclusion Polyp location,intraoperative bleeding and hypertension are the factors affecting the delayed hemorrhage after endoscopic resection of colorectal polyps.In clinical treatment,doctors need to pay more attention to patients,supervise and take care of patients,so as to eliminate the occurrence of delayed hemorrhage.
