Management of Rectal Prolapse
For complicated rectal prolapse with signs of shock or gangrene/perforation, immediate surgical treatment via an abdominal open approach is mandatory, while incarcerated prolapse without ischemia should first undergo attempted gentle manual reduction under sedation. 1
Initial Assessment and Conservative Management
Evaluation of Complicated Prolapse
For patients presenting with suspected complicated rectal prolapse, obtain:
- Complete blood count, serum creatinine, and inflammatory markers (C-reactive protein, procalcitonin, lactates) to assess patient status 1
- In hemodynamically stable patients with irreducible or strangulated prolapse: urgent contrast-enhanced abdomino-pelvic CT scan to detect complications and assess for colorectal cancer 1
- In hemodynamically unstable patients: do NOT delay treatment for imaging 1
Conservative Approach
For incarcerated rectal prolapse without signs of ischemia or perforation, attempt conservative measures with gentle manual reduction under mild sedation or anesthesia before proceeding to surgery. 1
However, in hemodynamically unstable patients, do not delay surgical management to attempt conservative treatment 1
Surgical Indications and Timing
Immediate Surgery (Emergency)
Patients with complicated rectal prolapse and signs of shock or gangrene/perforation of prolapsed bowel require immediate surgical treatment. 1
Urgent Surgery
Proceed urgently with surgery for patients presenting with:
- Bleeding from prolapsed tissue 1
- Acute bowel obstruction 1
- Failure of non-operative manual reduction 1
Surgical Approach Selection
Abdominal vs. Perineal Decision Algorithm
For complicated rectal prolapse with peritonitis: use an abdominal approach 1
For complicated rectal prolapse with hemodynamic instability: use an abdominal open approach 1
For complicated rectal prolapse without peritonitis or hemodynamic instability: base the decision between abdominal and perineal procedures on patient characteristics and surgeon expertise 1
Recent evidence shows that minimally invasive transabdominal approaches have gained significant popularity, increasing from 0% to 24.9% of cases, while demonstrating the lowest mortality rate (0.5%) compared to perineal approaches (1.7%) 2. Laparoscopic rectopexy consistently demonstrates lower recurrence rates and better functional outcomes compared to perineal techniques 3.
Open vs. Minimally Invasive Abdominal Surgery
In hemodynamically stable patients undergoing abdominal repair, the choice between open or laparoscopic surgery should be based on patient characteristics and surgeon expertise 1
However, minimally invasive approaches show lower minor complication rates (5.8%) compared to open approaches (11.1%) and perineal approaches (6.0%) 2. When feasible, minimally invasive techniques including laparoscopic and robotic approaches should be employed in appropriately selected patients 4.
Resection Decisions
For patients undergoing resectional surgery during prolapse repair: base the decision between primary anastomosis (with or without diverting ostomy) versus terminal colostomy on the patient's clinical condition and individual risk of anastomotic leakage 1
Important caveat: Bowel resection should be avoided in patients with preexisting diarrhea and/or incontinence, as these symptoms may worsen with resection 1
Adjunctive Pharmacological Management
In patients with strangulated rectal prolapse, administer empiric antimicrobial therapy due to risk of intestinal bacterial translocation. The regimen should be based on:
- Clinical condition of the patient 1
- Individual risk for multidrug-resistant organisms (MDRO) 1
- Local resistance epidemiology 1
Special Population Considerations
Elderly and High-Risk Patients
Elderly patients, those with significant medical comorbidities, or contraindications for abdominal surgery are often best candidates for perineal procedures, generally perineal proctosigmoidectomy (Altemeier procedure) 1. Despite higher recurrence rates (5-21%), perineal approaches remain valuable alternatives for high-risk patients due to being less invasive 1, 3.
Pediatric Patients
In children with rectal prolapse refractory to conservative management:
- Children below age 5: submucous hypertonic saline injection sclerotherapy is highly effective (83% cure rate) 5
- Children older than 5 with full-thickness prolapse: early definitive corrective surgery is recommended, as they do not respond to conservative measures or injection sclerotherapy 5
Key Clinical Pitfalls
Division versus preservation of lateral ligaments: Division of lateral ligaments is associated with less recurrent prolapse but more postoperative constipation 1. After posterior rectopexy, 50% of patients complain of severe constipation 1.
Perineal approach trade-offs: While perineal procedures have lower perioperative morbidity and shorter hospital stays, they carry higher recurrence rates (5-21%) compared to transabdominal rectopexy (0-8%) 1, 3.
Irreducible prolapse: When sugar application fails in irreducible prolapse, surgery should be performed early, with perineal resection being the most suitable emergency procedure 6.
