What are the treatment options for a patient with a rectal hernia?

Treatment of Rectal Hernia

Immediate Assessment and Stabilization

For complicated rectal prolapse (the most common form of "rectal hernia"), patients with signs of shock, gangrene, or perforation require immediate surgical treatment. 1

Initial Clinical Evaluation

• Obtain complete blood count, serum creatinine, and inflammatory markers (C-reactive protein, procalcitonin, lactates) to assess hemodynamic status and tissue viability 1
• In hemodynamically stable patients, perform urgent contrast-enhanced abdomino-pelvic CT scan to detect complications and rule out colorectal cancer 1
• Never delay surgical intervention in hemodynamically unstable patients to obtain imaging studies 1, 2

Non-Operative Management (For Uncomplicated Cases)

Manual Reduction Technique

For incarcerated rectal prolapse without ischemia or perforation, attempt conservative reduction first 1:

• Place patient in Trendelenburg position and administer IV sedation/analgesia 2
• Apply topical granulated sugar to prolapsed tissue for 10-15 minutes to reduce edema through hyperosmolar effect 2
• Alternative edema-reduction methods include 50% dextrose, 70% mannitol, or submucosal hyaluronidase 2
• Apply steady, gentle circumferential pressure with both hands, avoiding excessive force 2

When Conservative Management Fails

Do not delay surgical intervention if manual reduction fails, or if there are signs of ischemia, perforation, or hemodynamic compromise 1, 2

Surgical Management

Indications for Immediate Surgery (Strong Evidence)

• Shock or hemodynamic instability 1
• Gangrene or perforation of prolapsed bowel 1
• Strangulation with vascular compromise 2

Indications for Urgent Surgery

• Uncontrolled bleeding 1
• Acute bowel obstruction 1, 2
• Failed non-operative management 1

Surgical Approach Selection Algorithm

For hemodynamically unstable patients with peritonitis: perform open abdominal approach 1

For hemodynamically stable patients without peritonitis:

• Base decision between abdominal versus perineal approach on patient age, comorbidities, and surgeon expertise 1
• Perineal procedures (e.g., Altemeier procedure) have lower perioperative morbidity but higher recurrence rates (5-21%) versus transabdominal rectopexy (0-8% recurrence) 1, 3
• Elderly patients and those with significant comorbidities are best candidates for perineal approach 1
• Laparoscopic rectopexy has fewer complications and shorter hospital stay than open rectopexy 1, 3

Critical Surgical Considerations

• Avoid bowel resection in patients with preexisting diarrhea or incontinence, as these symptoms worsen with resection 1, 3
• After posterior rectopexy, 50% of patients develop severe constipation—counsel patients preoperatively 1, 3
• For resectional surgery, base decision between primary anastomosis (with/without diverting ostomy) versus terminal colostomy on clinical condition and anastomotic leak risk 1

Antibiotic Therapy

Administer empiric broad-spectrum antibiotics for strangulated rectal prolapse due to risk of bacterial translocation 1, 2

• Select regimen based on clinical condition, individual risk for multidrug-resistant organisms, and local resistance patterns 1, 2

Special Considerations for Rectocele (Posterior Vaginal Wall Prolapse)

Conservative Management First

• Start with dietary modifications, fluid management, bowel training, and constipation management 3
• Pelvic floor biofeedback therapy to correct underlying dysfunction 3
• Approximately 25% of patients respond to conservative therapy alone 3

Surgical Intervention for Rectocele

Surgery is necessary in less than 5% of patients with defecatory disorders—the vast majority should be managed conservatively 3

Consider surgery only after failed conservative therapy for symptomatic grade 3-4 prolapse 3:

• Stapled Transanal Rectal Resection (STARR) achieves 82% of patients with >50% reduction in obstructed defecation scores at one year 3
• However, STARR has 15% adverse event rate (infection, pain, incontinence, bleeding) and rare but serious complications (fistula, peritonitis, perforation) 3
• The correlation between symptom improvement and anatomical correction is weak—symptoms may persist despite anatomic repair 1, 3
• Long-term outcomes are disappointing, and STARR has not gained widespread acceptance in the United States 1

Perineal Hernia After Abdominoperineal Resection

For true perineal hernias occurring after rectal surgery, high-tension mesh repair through perineal approach shows 95% success rate with only 5% recurrence 4
