Clinical Research In Treating Grade Ⅳ Circular Mixed Hemorrhoid

Objective:To observe and compare the effect of surgical procedures for the improved operation(operation of rebuilding the structure of anal cushion and hemorrhoid area)in treating grade IV circular mixed hemorrhoid by normative scientific research design,and evaluate the safety of both methods.To provide a more complete method for surgical treatment on hemorrhoids.Methods:A total of 112 patients with grade IV circular mixed hemorrhoid who met the diagnostic criteria were included.They were divided into observation group and control group randomly,each group 56 cases.Patients of the observation group were treated by the improved operation,while the control group were MMH.Aspects such as the general information,operation time,intraoperative bleeding,hospital stay,hospital expenses,postoperative urinary etention(24h),postperative pain(1,3,7d),edema(1,3,7d),exfoliated hemorrhage after operation(7 ~ 10d),sphincter function(6m),anal stenosis(6m)and other aspects of the two groups were observed and compared.Also the effect and the safety of both groups were observed.Results:It was not statistically significant in general data between the two groups(P≥0.05),which was comparable between the two groups.The observation group was superior on those aspects of operation time,intraoperative bleeding,postoperative urinary etention(24h),postoperative pain(1d,3d,7d),postoperative edema(3d,7d),sphincter function(6m)and anal stenosis(6m).The difference was statistically significant(P<0.05).While there was no statistically significant difference in hospital stay,hospital expenses,edema(1d)and exfoliated hemorrhage after operation(7 ~ 10d).Also there was no difference in the effect and the safety of the two groups(P≥0.05).During the period of observation,no patients had seriously adverse reactions and both methods were safe.Conclusions:Both the improved operation and MMH are safe and effective method for treating of grade-IV circular mixed hemorrhoid.The former is superior on the aspects of operation time,intraoperative bleeding,postoperative urinary etention,postoperative pain,postoperative edema and sphincter function.
