Management of Rectocele

Initial Assessment and Symptoms

• Anal incontinence is a symptom of rectocele, which is a herniation of the rectum into the posterior vaginal wall, affecting patients with pelvic floor disorders 1
• Pelvic floor biofeedback therapy is a conservative treatment option to correct underlying pelvic floor dysfunction in patients with rectocele, as recommended by the American Gastroenterological Association 2

Surgical Approaches

• The selection of surgical approach for rectocele repair should be determined based on patient characteristics, such as age and comorbidities, and associated pelvic floor disorders, as suggested by the World Journal of Emergency Surgery 3
• The transanal approach, including Stapled Transanal Rectal Resection (STARR), aims to exclude redundant rectal mucosa associated with rectocele and is effective in reducing rectocele size, with an average reduction from 3.8 cm to 1.9 cm, according to the Clinical Gastroenterology and Hepatology 2, 4
• Ventral rectopexy is a recommended surgical approach for high rectoceles or those associated with other pelvic floor disorders, and can be performed open or laparoscopically based on patient characteristics and surgeon expertise, as recommended by the World Journal of Emergency Surgery 1, 3, 4

Outcomes and Considerations

• The correlation between symptom improvement and anatomical correction is often weak, and anatomical abnormalities may be caused by underlying functional disorders that are not corrected by surgery, as noted by the Clinical Gastroenterology and Hepatology 2, 4
• Rare but serious complications after STARR include fistula, peritonitis, and bowel perforation, with a higher risk of complications including infection, pain, incontinence, bleeding, as reported by the Clinical Gastroenterology and Hepatology 2, 4

Complications to Monitor

• Post-operative pain is a common complication after rectocele repair, affecting patients who undergo surgical intervention 1
• Infection, bleeding, and incontinence are potential complications after rectocele repair, and patients should be monitored closely, as recommended by the World Journal of Emergency Surgery 1, 3

Rectocele Surgery Treatment Approach

Indications for Surgical Intervention

• Symptomatic grade 3-4 rectal prolapse associated with rectocele requires surgical correction, as recommended by the American Gastroenterological Association, with a strength of evidence based on clinical guidelines 5

Surgical Approach Selection

• The American Gastroenterological Association suggests that symptomatic rectoceles that do not respond to conservative management may benefit from surgical intervention, such as Stapled Transanal Rectal Resection (STARR), which can reduce rectocele size and improve symptoms, with 82% of patients reporting >50% reduction in obstructed defecation scores at one year 5

Important Considerations and Pitfalls

• The correlation between symptom improvement and anatomical correction is often weak, and surgical repair does not always alleviate symptoms related to difficulty in defecation, as noted by the American Gastroenterological Association, highlighting the importance of careful patient selection and counseling, with a strength of evidence based on clinical experience 5

Follow-up and Outcomes

• Long-term outcomes of STARR are somewhat disappointing despite initial improvement, with variable success rates, as reported by the American Gastroenterological Association, emphasizing the need for careful follow-up and management, with a strength of evidence based on clinical studies 5

Treatment Options for Rectocele

Medical Management

• Medical management with emphasis on suppositories and enemas when biofeedback fails, as recommended by Clinical Gastroenterology and Hepatology 6

Treatment of Posterior Vaginal Wall Prolapse (Rectocele)

Initial Conservative Management

• The American Gastroenterological Association recommends starting with conservative measures, including dietary modifications, fluid management, bowel training programs, and management of constipation or diarrhea with medications if necessary 7
• Approximately 25% of patients will benefit from conservative therapies alone 7

When to Consider Surgery

• Surgery should only be considered after failure of conservative therapy and in patients with symptomatic grade 3-4 prolapse or rectoceles causing significant quality of life impairment, as recommended by the American College of Gastroenterology 8

Surgical Approach Selection Algorithm

• Laparoscopic rectopexy is associated with fewer post-operative complications and shorter hospital stay than open rectopexy, according to the American Society of Colon and Rectal Surgeons 9, 8
• Perineal procedures have lower perioperative morbidity but higher recurrence rates (5-21%) compared to transabdominal rectopexy (0-8%), as reported by the Society of American Gastrointestinal and Endoscopic Surgeons 9, 8

Important Complications to Counsel Patients About

• After posterior rectopexy, 50% of patients develop severe constipation, a complication that should be discussed with patients by the American Society of Colon and Rectal Surgeons 9, 8
• Bowel resection should be avoided in patients with preexisting diarrhea and/or incontinence as these symptoms may worsen, as advised by the American Gastroenterological Association 9, 8

Multidisciplinary Approach

• A collaborative approach between gynecologists and colorectal surgeons is ideal, particularly for complex cases with multiple pelvic floor disorders, as recommended by the American College of Obstetricians and Gynecologists 9, 8
• Pouch of Douglas protrusion is best addressed with sacrocolpopexy, usually performed in conjunction with other gynecologic procedures, according to the Society of Gynecologic Surgeons 9, 8

Key Pitfall to Avoid

• Surgery is necessary in less than 5% of patients with defecatory disorders - the vast majority should be managed conservatively with biofeedback therapy, as recommended by the American Gastroenterological Association 9, 8
