Clinical Studies Of Classified Diagnosis For Internal Rectal Prolapse By Anorectal Manometry

objective: On the basis of diagnosis for internal rectal prolapse by defecography, Classifiedits diagnosis combined morphological and metergasis by quantitative analysis of rectoanalmanometric parameter.Methods: Undertaking anorectal manometry after dividing patientswith internal rectal prolapse into two groups: Rectal mucosal prolapse, full thicknessintussusception.At the same time,setting up control group. Results: （1） Rectal mucosalprolapse : Compliance is normal （p＞0.05）, volume of earliest urge to defecate, themaximum tolerating and distending pressures degrades obviously (p^△△＜0.01), rectoanalinhibitory reflex exists,percentage sphincter relaxation seen is normal （p＞0.05）. Fullthickness intussusception: Compliance raises obviously （p^△＜0.05）, volume of earliesturge to defecate, the maximum tolerable increases obviously (p^△△＜0.01), but distendingpressures degrades (p^△△＜0.01), negative rate of rectoanal inhibitory reflex increases,percentage sphincter relaxation seen degrades obviously (p^△△＜0.01), Anal squeezePressures degrades (p^△△＜0.05).（2） Calculating by Rectal compliance on the point of themaximum tolerating: Rectal mucosal prolapse group, 15 in 18 patients are in normal range,coincidence is 83.3%. Full thickness intussusception group, 13 in 15 patients justo major,coincidence is 86.5% .Conclusion: Anorectal Manometry provides a new choice forClassified diagnosis of internal rectal prolapse.
