IUGA Opinion Paper on Obstructed Defecation: Management of Clinical and Proctographic Rectoceles

Obstructed defecation syndrome (ODS) is a defecatory abnormality with a sensation of incomplete evacuation, the need to strain at stool, the need for digitation in the vagina, the anus, or the perineum. Anterior rectocele and rectal intussusception are the frequent pathologies behind ODS. The review focuses on the assessment and treatment of obstructed defecation in women with rectocele, recto-enterocele and rectal intussusception in the remit of a urogynecologist.

A working subcommittee from the International Urogynecology Association (IUGA) Research and Development (R&D) Committee was formed with colorectal surgeons from the American Society of Colon & Rectal Surgeons (ASCRS). An initial document was drafted based on a literature review. The review focused on the treatment options of women with presenting with obstructed defecation and posterior compartment prolapse either on clinical examination or on imaging. After evaluation by the entire IUGA R&D Committee revisions were made. The quality of the evidence was graded and used to form consensus recommendations.

Ultrasound and dynamic MRI are helpful imaging modalities in triaging patients. A defecating proctogram to evaluate the size of rectal intussusception and enterocele is the standard investigation. Conservative therapies are effective first-line management options. The transvaginal native tissue rectocele repair is a safe and effective first-line surgical treatment in women with obstructed defecation.

When evaluating patients with obstructive defecation, it is important to address anatomy as well as function. In the absence of a clinically significant rectocele or enterocele during vaginal examination, in women with obstructed defecation, referral to a gastroenterologist or colorectal surgeon for further evaluation and management is recommended.
