![]() ![]() At least in part, an anorectal colonic reflex that results in enhanced contractions of the descending colon and rectum may contribute to bowel evacuation in individuals with SCI. Anorectal flexure TA the anteroposterior curve or angle, with convesity directed anteriorly, of the anorectal junction tonus of the puborectalis (muscle) produces the angle for maintaining fecal continence relaxation of the muscle allows the angle to be reduced for defecation. These manometric changes in response to DRS were accompanied by expulsion of barium oatmeal paste in every subject by the fifth DRS.ĭRS causes left-sided colonic activity in subjects with SCI. The frequency of contractions, as well as amplitude of contractions, during or immediately after DRS was not significantly different. The mean amplitude (+/- SEM) of the peristaltic contractions was 43.4 (+/- 2.2) mmHg. The mean number (+/- SEM) of peristaltic waves per minute increased from 0 at baseline to 1.9 (+/- 0.5/min) during DRS and 1.5 (+/- 0.3/min) during the period immediately after cessation of DRS (P < 0.05). In addition, evacuation of barium oatmeal paste (with the consistency of stool and introduced into the rectum and descending colon) was assessed simultaneously using fluoroscopic techniques. Colonic motility was assessed using a manometric catheter (affixed endoscopically to the splenic flexure) at baseline, during DRS, and after DRS. Six subjects with SCI were studied several hours after a bowel care session. norectal flexure TA the anteroposterior curve or angle, with convesity directed anteriorly, of the anorectal junction tonus of the puborectalis (muscle) produces the angle for maintaining fecal continence relaxation of the muscle allows the angle to be reduced for defecation. This study assessed the effect of DRS on colonic motility. However, the basis for the efficacy of DRS is not known. Stimulation of the anal canal and lower rectum, accomplished using a gloved finger (so-called digital rectal stimulation or DRS) is often used as an adjunct to laxatives and enemas to facilitate bowel evacuation. Difficulty with evacuation (DWE) is a major problem after spinal cord injury (SCI). ![]()
