Revision as of 00:05, 30 September 2019
Background
- Circumferential protrusion of part or all layers of the rectum through the anal canal
- Complications are rare and include bleeding and ulceration
Risk factors
- Extremes of age
- Chronic constipation
Types
- Prolapse involving the rectal mucosa only
- Rarely protrudes more than 2 to 3 cm beyond the anal verge
- Anal edges appear everted
- Radially directed folds
- No sulcus between extruded mucosa and anus
- Frequently associated with 3rd and 4th degree hemorrhoids
- Prolapse involving all layers of the rectum
- May protrude up to 15 cm
- Anus appears normal
- Prolapse appears as red, ball-like mass with concentric folds
- Sulcus may be palpated between the extruded bowel and anus
- Intussusception of upper rectum into and through the lower rectum
Clinical Features
Most frequent complaint at the time of clinical presentation:[1]
- Sensation of a protruding rectal mass (98.7%)
- Painful defecation (36%)
- Fecal incontinence (38.7%)
- Rectal bleeding (25.3%)
- Constipation (25.3%)
- Rectal ulcer (8%)
- Patients may mistake prolapsed mucosa for hemorrhoids
Differential Diagnosis
Anorectal Disorders
- Anal fissure
- Anal fistula
- Anal malignancy
- Anal tags
- Anorectal abscess
- Colorectal malignancy
- Condyloma acuminata
- Constipation
- Crohn's disease
- Cryptitis
- GC/Chlamydia
- Hemorrhoids
- Pedunculated polyp
- Pilonidal cyst
- Proctitis
- Pruritus ani
- Rectal foreign body
- Rectal prolapse
- Syphilitic fissure
Evaluation
- Clinical diagnosis
Management
Children
- Reduce via slow steady pressure applied to prolapsed segment
- Prevent constipation
- Refer for evaluation of underlying condition (CF, pelvic floor weakness, diarrhea)
Adults
- Reduction
- Thumbs over luminal surfaces medially and fingers grasp outer walls laterally
- Apply continuous pressure first with thumbs followed by internal rolling of fingers
- After reduction perform digital rectal exam to evaluate for rectal mass/polyp
- Thumbs over luminal surfaces medially and fingers grasp outer walls laterally
- Difficult reduction
- Prolonged prolapse may lead to rectal wall edema
- Adequate sedation and analgesia is key to successful reduction
- Can incorporate a perianal block in certain cases
- Can place granulated sugar (not synthetic sweeteners) over prolapsed rectum
- Wait 15 min for edema to subside and re-attempt
- Failed reduction
- Obtain emergent surgical consultation
Disposition
- Discharge
- Refer all patients for colonoscopy and surgeon for consideration of repair
