Abstract:
Objective Retrospectively analyzed the data of patients with delayed bleeding after colorectal polypectomy,summarized the risk factors and treatment methods of bleeding patients,and provided the basis for further prevention and treatment of postoperative delayed bleeding.Methods Collected the clinical data of 1 243 patients who were admitted into the department of gastroenterology of third affiliated hospital of the third military medical university and accepted polypectomy with colonoscopy from January 2014 to December 2016.Divided these patients into the bleeding group and the non-bleeding group according to whether there was delayed bleeding after surgery.The age,size of polypus,location of polypus,postoperative pathology of the two groups were compared and the postoperative treatment of bleeding was evaluated.Results Among the 1 243 patients underwent colorectal polypectomy,there were 14 cases of delayed bleeding,and the incidence was 1.13%.In the bleeding group,there was 1 case of secondary delayed bleeding and 2 cases of bloody stool after hemostasis for the delayed bleeding.Delayed bleeding occurred at (4.73±2.49)days after surgery.The predilection site of of polypus was rectum in the bleeding group (7/14,50%), and the diameter of polypus was (16.65±4.91)mm in the bleeding group,which was lager than (8.07±4.23)mm in the non-bleeding group with statistical difference (P<0.05).The proportion of hypertensive and diabetic patients in the bleeding group was significantly higher than that in the non-bleeding group (P<0.05).Juvenile polyps and tubular adenoma with high grade intraepithelial neoplasia were more common in the bleeding group(P<0.05).The bleeding group achieved good hemostatic effect by purse suture,hemostatic clip,electrocautery or injection hemostasis.Conclusion Older age,hypertension and diabetes,lager size of polypus,rectum polypus,juvenile polyps and tubular adenoma with high grade intraepithelial neoplasia were risk factor for delayed bleeding.In the event of delayed bleeding,different choice of purse suture,hemostatic clip,electrocautery or injection hemostasis according to different wounds can achieve the desired effect.
