Dyssynergic Defecation

Correcting defecatory technique through pelvic floor physiotherapy is hypothesised to reduce recurrent diverticulitis risk. Dyssynergic defecation is characterised by inadequate rectal propulsion, insufficient anal sphincter relaxation, or both. Dyssynergic defecation is proposed to generate repeated transient high intraluminal pressures in the distal colon and rectum. The investigators hypothesise that pressure spikes from dyssynergic defecation contribute to structural colonic wall changes seen in diverticulosis. The investigators hypothesise that a high-pressure, high-turbulence environment may obstruct diverticula and precipitate diverticulitis.
