Symptoms
Internal intussusception may be asymptomatic, but common symptoms include:
- Fecal leakage
- sensation of obstructed defecation (tenesmus).
- Pelvic pain.
- Rectal bleeding.
Recto-rectal intussusceptions may be asymptomatic, apart from mild obstructed defecation. "interrupted defaecation" in the morning is thought by some to be characteristic.
Recto-anal intussusceptions commonly give more severe symptoms of straining, incomplete evacuation, need for digital evacuation of stool, need for support of the perineum during defecation, urgency, frequency or intermittent fecal incontinence.
It has been observed that intussusceptions of thickness ≥3 mm, and those that appear to cause obstruction to rectal evacuation may give clinical symptoms.
