PURPOSE: Rectal prolapse is frequently associated with fecal incontinence; however, the relationship is questionable. The study was designed to evaluate fecal incontinence in a large consecutive series of patients who suffered from rectal prolapse, focusing on both past history, anal physiology, and imaging.
METHODS: Eighty-eight consecutive patients who suffered from an overt rectal prolapse (72 women, 16 men; mean age, 51.1 +/- 19.5 years) as a main symptom were analyzed; 48 patients also experienced fecal incontinence compared with 40 without incontinence. Logistic regression analyses were performed.
RESULTS: The two groups of patients did not differ with respect to parity, weekly stool frequency, main duration of symptoms before referral, occurrence of dyschezia, and digital help to defecate. Patients with prolapse who were older than 45 years (odds ratio (OR), 4.51 (1.49-13.62); P = 0.007) and those with a past history of hemorrhoidectomy (OR, 9.05 (1.68-48.8); P = 0.01) were significantly more incontinent. Incontinent group showed frequent internal anal sphincter defect compared with the continent group (60 vs. 6.2 percent; P = 0.0018).
CONCLUSIONS: In patients with overt rectal prolapse, the occurrence of fecal incontinence needs special consideration for age and previous hemorrhoid surgery as causative factors. Anal weakness and sphincter defects are frequently observed.
