Analysis of Risk Factors of Delayed Bleeding after Endoscopic Submucosal Dissection for Digestive Tract Lesions
Objective To investigate the risk factors of delayed bleeding after endoscopic submucosal dissection(ESD)for digestive tract lesions.Methods Clinical data of 160 patients with digestive tract lesions treated with ESD were retrospec-tively analyzed,and relevant clinical,endoscopic and pathological data of the patients were analyzed.Patients were divided into bleeding group and non-bleeding group according to whether delayed bleeding occurred.The above data were compared be-tween the two groups,and the risk factors of delayed bleeding after ESD were summarized.Results There was no significant difference between the two groups in terms of age,gender,complications,and whether they had taken anticoagulant drugs in the past(P>0.05).The size of lesions and the proportion of surface ulcers in bleeding group were higher than those in non-bleeding group(P<0.05).Total resection of the two groups was compared(P>0.05).The operation time and the proportion of obvious bleed-ing in the bleeding group were higher than those in the non-bleeding group(P<0.05).Lesion size,surface ulcers,operation time and obvious bleeding during operation were all related factors affecting delayed bleeding after digestive tract lesions(P<0.05).Conclusions Patients with digestive tract lesions with large lesions,surface ulcers,long operation time and obvious bleeding during operation have higher risk of postoperative delayed bleeding,and should be treated as soon as possible.
