Evaluation and management of defecatory dysfunction in women

Changes in bowel symptoms after different pelvic organ prolapse surgeries among elderly women at the 1-year follow up

OBJECTIVE

To investigate the prevalence of bowel symptoms in patients with pelvic organ prolapse (POP), to evaluate the changes in bowel symptoms after different POP surgeries, and to identify risk factors for unrelieved bowel symptoms.

METHODS

This was an observational prospective cohort study conducted at Peking University First Hospital from 2020 to 2021. Demographic, clinical, and therapeutic data were collected. Participants underwent POP Quantification examination and completed the Pelvic Floor Distress Inventory-20 questionnaire at baseline and 1 year postoperatively.

RESULTS

The prevalence of bowel symptoms and bothersome bowel symptoms in women with POP was 46.38% and 24.40%, respectively. Surgical correction of prolapse was associated with significant relief in bowel symptoms (P < 0.05). Colpocleisis may relieve bowel symptoms better than reconstructive surgeries (41% vs. 31%, P = 0.048). However, 35% of women had at least one bowel symptom at the 1-year follow up. A long perineal body (Pb) and levator ani muscle injury were found to be predictors of unrelieved bowel symptoms in patients undergoing colpocleisis and those undergoing reconstructive surgery, respectively (odds ratio [OR] 2.306, 95% confidence interval [CI] 1.112-4.783, P = 0.025 and OR 3.245, 95% CI 1.266-8.317, P = 0.014, respectively), and perineoplasty was a protective factor for women who underwent colpocleisis (OR 0.102, 95% CI 0.025-0.417, P = 0.001) CONCLUSION: Women with POP have a high prevalence of bowel symptoms. Although bowel symptoms can be relieved after POP surgeries, one-third of women still experience bowel symptoms. A long Pb and levator ani muscle injury were associated with unrelieved bowel symptoms, while perineoplasty was a protective factor.

Defecatory Dysfunction

Normal defecation is a complex and coordinated physiologic process that involves the rectum, anus, anal sphincter complex, and pelvic floor muscles. Any alteration of this process can be considered defecatory dysfunction, a term that covers a broad range of disorders, including slow-transit constipation, functional constipation, and functional or anatomic outlet obstruction. Evaluation should include history, physical, and consideration of additional testing such as colonoscopy, colonic transit studies, defecography, and/or anorectal manometry. Depending on the etiology, management options can include conservative measures such as dietary or lifestyle modifications, medications, pelvic floor physical therapy, or surgical repair.

Obstructed defecation syndrome: a diagnostic and therapeutic challenge

Obstructed defecation syndrome produces constipation with anal blockage and a feeling of incomplete evacuation, due to either anatomic and functional causes. This is a complex and multifactorial entity due to diverse etiological factors that may coexist in many patients. Therefore, a diagnostic approach requires structural and functional assessment. The concordance between findings of diagnostic tests is suboptimal, thus an individualized analysis is mandatory in each patient. Therapeutic strategies require the best understanding of anatomic and functional aspects. Consequently, this entity is a diagnostic and therapeutic challenge.
