Correlation between rectal dilation and Wexner score after PPH for outlet obstructive constipation
[Objective]To study the correlation between rectal dilatation and Wexner score after procedure for prolapse and hemorrhoids(PPH)based on defecography.[Methods]The data of 90 patients with outlet obstructive constipation were analyzed.The study group included 60 patients with rectal dilatation,while the control group included 30 patients without rectal dilatation.Both groups received PPH treatment.Evaluation parameters:maximum anteroposterior diameter,left and right diameter,upper and lower diameter,and rectal volume.Wexner score was used to evaluate defecation function,and the effect of rectal dilation on Wexner score after PPH for outlet obstructive constipation was compared.[Results]The Wexner scores of the study group before and after treatment were 26.2±0.7 and 24.3±0.4 respectively,with no significant difference(P＞0.05).After treatment,Wexner score was positively correlated with the maximum anteroposterior diameter of rectum 7.23±1.04 cm,left and right diameter 8.58±2.48 cm,upper and lower diameter 19.42±0.27 cm and rectal volume 78.41±3.22 cm3(P＜0.05),and rectal volume was positively correlated with the maximum anteroposterior diameter,left and right diameter,upper and lower diameter of rectum(P＜0.05).The Wexner scores of the control group before and after treatment were 20.1±0.1 and 6.8±0.2 respectively,with a statistically significant difference(P＜0.05).[Conclusion]Rectal dilation of outlet obstructive constipation affects Wexner score after PPH operation.It may be better for treatment and prognosis to know the degree of rectal dilation before operation.
