Are rectoceles the cause or the result of obstructed defaecation syndrome? A prospective anorectal physiology study

Abstract

Rectoceles are not associated with an increased severity of ODS-type symptoms, anorectal abnormalities or pelvic floor dyssynergia in patients with ODS. This suggests that rectoceles may be the result, rather than the cause, of ODS.

The association between a positive lactulose methane breath test and rectocele in constipated patients

“…It is not clear whether rectoceles are a cause or a result of constipation. A recent study suggests that rectoceles are more likely to be a result, rather than the cause of obstructed defecation syndrome (26). This means that surgical procedures intended to correct a rectal wall prolapse are not effective for improving symptoms.…”

Functional Disorders: Rectocele

“…With no significant manometric or other radiographic differences identified between patients with and without rectocele, the authors conclude that the presence of a rectocele is likely an incidental side effect of ODS rather than a significant cause. 40 Furthering the confusion about the relationship of a rectocele with ODS is the lack of correlation between objective measurements of rectoceles and severity of symptoms or success of repair. Multiple studies from the gynecologic literature have failed to show correlation between the degree of pelvic organ prolapse and defecatory dysfunction.…”

Comparison of laparoscopic subtotal colectomy with posterior vaginal suspension and laparoscopic subtotal colectomy with transvaginal repair for patients with slow-transit constipation complicated with rectocele: a non-randomized comparative study in a single center

“…Some researchers even believe that rectocele, internal rectal mucosal prolapse or intussusception is a manifestation or a result of pelvic floor descent or disorders, and that they are substantially the same disease. Treating rectocele alone without considering other causes would not bring satisfactory curative effects [20].…”
