Abstract
Surgery for isolated internal rectal intussusception is controversial due to high morbidity Therefore there is interest in other forms of treatment that are safe and effective The aim of this study was to determine outcome and identify predictors for success of biofeedback therapy in patients with rectal intussusceptionA total of 34 patients 7 men had undergone at least 2 biofeedback sessions The patients had a mean age of 685 years SD=114 years In the 27 patients with constipation the frequency of weekly spontaneous bowel movements mean±SD was 20±68 before and 41±46 after biofeedback p005 The frequency of weekly assisted bowel movements decreased from 38±35 before to 15±22 after therapy p0005 The number of patients who experienced incomplete evacuation decreased from 17 63 to 9 33 p005 Thirty–three percent of patients had complete resolution of the symptoms 19 had partial improvement and 48 had no improvement Patients with constipation lasting less than nine years had a 78 success rate vs 13 in patients who were consti– pated more than 9 years p001 In seven patients with incontinence the frequency of daily incontinence episodes decreased from 10±07 before to 007±006 after biofeedback p005 The fecal incontinence score decreased from 131±42 before to 46±36 after treatment p0005 Two patients 29 were completely continent following biofeedback 2 had partial improvement and 3 43 had no significant improvement There was no mortality in either groupBiofeedback is a safe and effective treatment option for constipation and fecal incontinence due to rectal intussusception in patients who are willing to complete the course of treatment Long–standing constipation is less effectively cured by biofeedback
