Abstract:
OBJECTIVES: To analyze the findings of rectal intussusception and to find the other accompanied functional anorectal diseases. MATERIALS AND METHODS: We analyzed defecograms in 25 patients with rectal intussusception among 77 patients taken with obstructed defecatory symptom. Females were 16 (64%), males were 9 (36%), and the mean age was 55 years old. The changes of anorectal angle (ARA) and movement of anorectal junction were measured, and the morphologic changes of rectal wall during defecation were analyzed. RESULTS: ARAs measured by central axis method (CAM), the mean angles were 114.6, 102.2, and 119.8 degree, respectively in resting, squeezing, and straining period. By posterior wall methods (PWM), those were 86.7, 72.0, 93.3 degree. The differences of ARA between resting and straining period were 5.2, 6.6 degree, respectively by CAM and PWM. The mean descent of anorectal junction during defecation was 0.83 cm. The most frequent finding associated with rectal intussusception was rectocele (12 cases;48%). The other accompanied findings were 9 spastic pelvic floor syndrome (36%) and 4 fecal incontinence (16%). Total 18 patients out of 25 patients were accompanied with other functional anorectal diseases (72%). CONCLUSIONS: Recognition of rectal intussusception with accompanied diseases would be important for the proper treatment planning.
