Rectal prolapse — Clinical Guidelines

Overview

Rectal prolapse occurs when the rectal walls protrude through the anal canal. It can be partial or complete, involving the mucosa, submucosa, or full thickness of the rectum 1 4 9.

Diagnosis

Clinical Presentation: Visible protrusion of rectal tissue per anus 1 4.

Physical Examination: Essential for grading severity (1st, 2nd, or 3rd degree) 1 9.

Imaging: Rarely necessary but can be useful in complex cases, especially for complications like evisceration 1 6.

Grading:

- 1st degree: Mucosal prolapse - 2nd degree: Mucosal and submucosal prolapse - 3rd degree: Full-thickness rectal prolapse 1 9.

Management

Conservative Management: Pelvic floor muscle training (PFMT) for mild cases 2.

Surgical Interventions:

- Altemeier's Procedure: Utilizing LigaSure Vessel Sealing System in geriatric patients 3. - Laparoscopic Approaches: Laparoscopic rectopexy shows excellent early results 7 8. - Thiersch Procedure: Performed using a novel encircling instrument for simplicity and reduced trauma 10. - Graciloplasty: Transposition of gracilis muscles for complete prolapse 11. - Parasacral Approach: For third-degree prolapse, offering posterior fixation 13. - Lockhart-Mummery Procedure: Effective for intractable pediatric cases 14.

Special Populations

Pediatrics: Rectal prolapse often self-limiting; surgical options like Lockhart-Mummery procedure for intractable cases 14.

Elderly: Surgical techniques adapted for geriatric patients, such as LigaSure in Altemeier's procedure 3.

Comorbidities: Full-thickness prolapse may indicate underlying intraabdominal pathology requiring thorough investigation 9.

Key Recommendations

Consider Pelvic Floor Muscle Training (PFMT) for Mild Cases to manage symptoms conservatively (Evidence: Moderate) 2.

Laparoscopic Rectopexy is recommended for complete rectal prolapse due to its excellent early outcomes (Evidence: Moderate) 7 8.

Surgical Intervention should be tailored to patient age and comorbidities, with techniques like LigaSure in geriatric patients showing feasibility and safety (Evidence: Weak) 3.

Comprehensive Evaluation for full-thickness prolapse to rule out underlying intraabdominal pathology (Evidence: Moderate) 9.

Lockhart-Mummery Procedure for intractable pediatric rectal prolapse offers favorable results (Evidence: Weak) 14.
