Methods: Forty -seven IBS patients with the constipation predominant type were randomly divided into the treated group ( n =24) and the control group ( n =23). Another group of 22 healthy subjects was set up for healthy control. The treated group was treated with modified SNS, and the control group was treated with Cisapride, the therapeutic course for both groups was 8 weeks. The changes of symptom scoring and anorectal manometry (the anorectal resting pressure, anal tract systolic pressure, anal tract diastolic pressure, rectal threshold feeling, maximal tolerance volume of rectum, and rectum compliance) of these two groups were recorded respectively and compared with each other. Results: Compared with the healthy control group, the rectal threshold feeling, maximal tolerance volume of rectum and rectal compliance of the treated groups got reduced significantly before treatment ( P <0.05). After treatment, the symptom scoring, rectal threshold feeling and maximal tolerance volume of rectum were improved in both groups ( P <0.05), and the improvement of the treated group was more significant than that of the control group( P <0.01). The total effective rate and recurrence rate of the treated group were superior to those of the control group significantly ( P <0.05, P <0.01).Conclusion: SNS has good effect on IBS of the constipation predominant type.展开更多

Our results showed that there was no significant dif- ference between the constipation group and the control group in anal sphincteric resting pressure and anal maximal squeezing pressure. The minimum relaxation volume, the rectal defecatory threshold, the rectal maximal tolerable volume and the rectal compliance in the patients were significantly higher than those in the controls (P< 0. 01 or P< 0. 05). It is concluded that patients with chronic idio- pathic constipation have anorectal motility disturbances.展开更多

Methods: The total of 135 cases were divided into healthy group, RQMI treated group, Maren pill (MRP) treated group and prepulsid (PPS) treated group, their anal maximal voluntary squeez pressure, rectoanal contraction reflex, rectoanal inhibitory reflex, defecation reflex, rectal volume sensory threshold and rectal maximal tolerable volume were observed. Results: The rectal sensory function of patients weakened obviously and anal sphincter reactivity reduced as compared with those of healthy person (P<0.01), and both were improved by RQMI treatment (P<0.05). Conclusion: RQMI is superior to MRP and prepulside in improving anorectal dynamic abnormality in constipation patient of asthenia type.展开更多
