Rectocele Treatment in the Elderly
Pelvic floor biofeedback therapy should be offered as first-line treatment for symptomatic rectocele in elderly women, with surgery reserved only for patients who fail conservative management after an adequate trial and have severe symptoms that markedly impair quality of life. 1
Initial Conservative Management
Begin with pelvic floor biofeedback therapy, which achieves symptom improvement in more than 70% of patients with defecatory disorders, supporting its use before any operative intervention 1
Address diarrhea first if present, as it is the single most important risk factor for anorectal dysfunction (odds ratio ≈ 53); control of diarrhea must precede any invasive therapy 1
Implement conservative bowel-management measures including dietary modification, fluid regulation, and constipation treatment, which provide benefit to roughly 25% of patients 1, 2
Ensure patient and therapist motivation, as the frequency and intensity of the retraining program significantly influence biofeedback success 1
Involve behavioral psychologists and dietitians when needed to enhance therapeutic outcomes 1
Continue conservative therapy for several months before considering surgical options 1
Indications for Surgical Intervention
Surgery is required in fewer than 5% of patients with defecatory disorders and should be considered only after an adequate trial of conservative therapy has failed 1, 2
Clinically significant rectoceles that preferentially fill and/or fail to empty on defecating proctogram constitute a clear indication for operative repair 1
Large rectoceles (>4 cm) are more likely to be associated with symptoms such as difficult defecation and may warrant earlier surgical consideration 3
Surgery should be discussed when symptoms cause significant deterioration in quality of life despite conservative measures 4
Surgical Approach Selection for Elderly Patients
For Low or Mid-Level Rectoceles:
Transvaginal posterior colporrhaphy is the preferred technique for isolated low or mid-level rectoceles (often accompanied by cystocele or uterine prolapse) 1
This approach can be performed under regional anesthesia, reducing physiologic stress in frail patients 1, 2
The perioperative safety profile makes it particularly suitable for elderly patients with comorbidities 2
For High Rectoceles or Multiple Pelvic Floor Disorders:
Transabdominal rectopexy is more suitable when high rectocele is present and/or associated with various disorders of pelvic stasis 4
Laparoscopic approaches, including ventral rectopexy, should be limited to carefully selected elderly patients with ASA grade I–II, no major cardiopulmonary disease, and good functional status 1, 2
For Frail or High-Risk Patients:
Perineal approaches (rectosigmoidectomy or Delorme's procedure) have lower perioperative morbidity and are preferred over abdominal approaches in patients ≥80 years old with comorbidities 2
These procedures can be performed under regional anesthesia with lower physiologic stress 2
STARR Procedure – Important Limitations
The stapled transanal rectal resection (STARR) procedure has not gained widespread acceptance in the United States and carries significant limitations 1
Approximately 15% of patients undergoing STARR experience adverse events including infection, pain, incontinence, bleeding, fistula, peritonitis, and bowel perforation, some severe enough to require additional surgery 1
Symptom improvement after STARR correlates poorly with rectocele size or anatomic correction, and long-term outcomes are disappointing because the procedure does not address underlying pelvic-floor dysfunction 1
While some studies show STARR may be superior to posterior colporrhaphy in treating obstructed defecation syndrome symptoms, the complication profile must be carefully weighed 5
Decision-Making Framework for Elderly Patients
The decision to pursue or withhold surgery must incorporate:
Estimates of perioperative mortality and life expectancy 6, 2
Patient-centered priorities and primary goals (prolongation of life versus maintenance of independence and symptom relief) 6, 2
Fit elderly patients with good physical and mental status may undergo standard surgical approaches, whereas frail patients with limited physiological reserve should be offered alternative, less-invasive treatments 6, 2
The overarching goal is to prioritize quality of remaining life, independence, and symptom relief rather than solely achieving anatomic correction 1, 2
Critical Pitfalls to Avoid
Do not proceed to surgery without first completing an adequate (several-month) trial of biofeedback therapy with a motivated patient and therapist 1
Exclude reversible causes such as bile-acid malabsorption, bacterial overgrowth, or medication effects before considering invasive interventions 1
Do not assume that anatomic abnormalities automatically require surgical correction; many rectoceles arise from excessive straining and pelvic-floor dysfunction that are not resolved by surgery 1
Recognize that successful anatomic repair does not guarantee functional improvement—symptoms may improve despite modest anatomic change and vice versa 1
Avoid bowel-resection procedures in elderly patients with pre-existing diarrhea or incontinence, as these symptoms are likely to worsen 1, 2
Discuss the risk of postoperative constipation, which affects up to 50% of patients, during informed consent 1, 2
Repeated manual reduction attempts should be avoided to prevent additional trauma if dealing with prolapse 7
Predictors of Poor Response to Conservative Therapy
These factors may prompt earlier surgical consideration:
Prior anorectal surgery, which can alter sphincter mechanics and predicts limited benefit from biofeedback 1
Presence of rectal prolapse or severe pelvic-floor descent, indicating structural problems beyond the scope of muscle retraining 1
Neurologic impairments (dementia, stroke, spinal cord injury, Parkinson's disease, diabetic neuropathy) that often render defecatory dysfunction permanent despite conservative measures 1
