Abstract    Stapled transanal rectal resection (STARR) has been introduced as a novel surgical approach for obstructed defecation syndrome caused by rectocele and rectal intussusception. Many reports have suggested the short-term success rate after STARR varies between 67% and 94%. Midterm outcome reveals 4.3%-17.1% of symptom recurrence rate. However, the improvement declines slightly according to the long-term results. The main complication after STARR is fecal incontinence which involves about 8.8% to 10.7% of patients. Defecography research proves that STARR procedure correct both rectocele and rectal intussusception significantly. The symptom improvement is related with the defecography results after the operation. Decreased maximum tolerable volume is reported after STARR according to anorectal manometry. The defecography results are valuable to predict the outcome after STARR.
