BACKGROUND: Stapled transanal rectal resection is a novel surgery for @entity3885 . Few data on the functional and morphologic outcome after the surgery have been reported. OBJECTIVE: This study aimed to evaluate the functional and morphologic outcome after stapled transanal rectal resection. DESIGN: This is a prospective study of consecutive @entity1 undergoing transanal rectal resection. SETTING: The study was conducted at a tertiary referral hospital, Beijing, China, from May 2007 to May 2009. @entity1 : Eighty-six consecutive female @entity1 with @entity3885 were carefully selected. INTERVENTIONS: All @entity1 underwent stapled transanal rectal resection. MAIN OUTCOME MEASURES: The main outcome measures were @entity1 ' symptoms, @entity3885 score, Wexner @entity322 score, anorectal manometry and defecography before and 1 year after surgery. RESULTS: The occurrence of all symptoms were significantly reduced after the procedure (P < .0001). @entity3885 score was decreased from 18.17    4.68 preoperatively to 7.36    3.52 postoperatively (P < .0001) with the Wexner @entity322 score unchanged. Maximum tolerable rectal volume was significantly decreased (236.08    50.00 vs 205.25    29.60, P < .0001) after surgery with anal sphincter pressures unchanged. Postoperative defecography was performed in 64 @entity1 . Rectocele disappeared in 40 of 62 @entity1 . The depth of rectocele was reduced from 35.40    4.58 mm preoperatively to 19.77    9.19 mm postoperatively (P < .0001). Incomplete evacuation disappeared in 41 of 51 @entity1 . Intussusception was completely corrected in 39 of 56 @entity1 . The reduction of @entity3885 score was greater in @entity1 with both rectocele and intussusception corrected than others (12.75    2.24 vs 9.17    3.47; P < .0001). LIMITATIONS: This study was limited owing to the lack of a control group and the medium-term results. CONCLUSIONS: Stapled transanal rectal resection is an effective procedure for @entity3885 . The functional outcome is good with the preservation of sphincter function and continence postoperatively. The morphologic outcome confirmed its efficacy in correcting rectocele and intussusception, and correlated well with clinical improvement.
