Usefulness of psyllium in rehabilitation of obstructed defecation

Abstract

After rehabilitation of obstructed defecation, some patients became symptom-free and many had an improved ODS score. Psyllium is helpful for volumetric rehabilitation: patients who consumed psyllium had lower post-rehabilitative CRST values than subjects were on high-fiber diet.

Systematic review: dietary fibre andFODMAP‐restricted diet in the management of constipation and irritable bowel syndrome

“…In 2011, Pucciani et al . conducted a single‐blind RCT in Italy, in patients with obstructed defecation . Forty‐five patients (100% female) with a mean age of 55.2 years, were recruited and 21 were randomised into Group 1, a high‐fibre diet arm, and 24 were randomised into Group 2, a psyllium arm.…”

Effect of a new synbiotic supplement on symptoms, stool consistency, intestinal transit time and gut microbiota in patients with severe functional constipation: a pilot randomized double-blind, controlled trial

“…Psyllium has been recently shown to be even more suitable than a high-fiber diet in terms of volumetric rehabilitation for the treatment of patients affected by obstructed defecation [14]. However, there is lack of evidence relating the effectiveness of psyllium to changes in the gut microbiota composition and identifying the microbiota species most affected: For these reasons, the effect of psyllium is generally suggested to be related to its bulking effect [15].…”

Influence of Lactitol and Psyllium on Bowel Function in Constipated Indian Volunteers: A Randomized, Controlled Trial

“…The sample size was based on the comparison of change in bowel movements per week from baseline to EOS between the 3 treatment groups and placebo. Based on the literatures, a standard deviation of 3–5 for bowel movements per week and an effect size of 2–4 more bowel movements per week after treatment were assumed [25,37,38,39,40,41,42]. Taking into account a discontinuation rate of approximately 10%, 43 volunteers per treatment group—i.e., 172 volunteers in total—were recruited to obtain approximately 40 volunteers per treatment group, providing 80% power for statistically significant changes in bowel movements/week.…”
