Abstract: Objective:To evaluate the effects of the conventional suturing hemorrhoid artery during the procedure for prolapse and hemorrhoids(PPH) on preventing post-operative hemorrhage.Methods:Two hundred Ⅲ and Ⅳ degree hemorrhoids patients without the history of hemorrhoid surgery were randomly divided into the conventional suturing hemorrhoid artery during the PPH group(group A,96 cases) and single PPH group(group B,104 cases).The operation and postoperative complications between two groups were compared.Results:The differences of the surgery duration(minute),number of haemorrhoids artery pulse and length of stay(day) between two groups were not statistically significant(P>0.05).The score of the postoperative maximum pain intensity in group A was significantly higher than that in group B(P<0.01).The significant anal bulge feeling in 78 cases of group A(81.13%) were observed.The differences of the severe anal bleeding,postoperative nausea or vomiting,urinary retention,perianal swelling,rectoscopy,constipation and anastomotic stenosis between two groups were not statistically significant(P>0.05).Conclusions:The conventional suturing hemorrhoid artery during the PPH can not effectively prevent the post-operative hemorrhage,and increase the anal swelling pain.The suturing hemorrhoidal artery can be used in some specific conditions.
