目的 探讨Miles手术重建盆底腹膜困难时的处理对策。方法 对Miles手术重建盆底腹膜困难的患者，根据其大网膜的解剖情况，将带血管蒂大网膜经左或右结肠旁沟放入骶前腔，利用大网膜去填塞骶前腔或修补盆底腹膜缺损。结果 3例患者分别用带蒂大网膜加气囊填塞骶前腔、带蒂大网膜单纯填塞骶前腔、带蒂大网膜修补盆底腹膜等方法，减轻了缝合盆底腹膜时的张力，使盆底腹膜得以顺利重建。结论 用带血管蒂大网膜填塞骶前腔或修补盆底腹膜缺损，可防止Miles术后并发症发生，促进患者早日康复。
Objective Both stapled transanal rectal resection (STARR) and vaginal bridge repair are new operative techniques for treatment of rectocele transanal and transvaginal, respectively. In this study we observe the clinical outcomes for STARR as compared with vaginal bridge repair procedure. Methods The clinical data of 31 patients with obstructive defecation syndrome from January 2007 to May 2009 were retrospectively analyzed. The patients were divided into 2 groups according to different operative approach: STARR group (n=18) and bridge repair suture group (n=13). The clinical outcomes observed were operative time, blood loss, length of stay, cost of hospitalization, complication and the improvement of obstructed defecation syndrome. Results There was no difference in the age and severity in the patients of two groups. Evaluation of the clinical outcomes showed 16 (88.9%) patients in the STARR group and 6 (46.2%) in the bridge repair suture group reported improvement in symptoms (P=0.017). STARR had a shorter operative time (24.6 min vs. 33.2 min， Plt;0.01), less estimated blood loss (3.9 ml vs. 16.2 ml， Plt;0.01), more costly (10 743 yuan vs. 3 543 yuan, Plt;0.01) and a higher anal incontinenc rate but reversible. The length of stay was similar (average 6 d). Conclusion The stapled transanal rectal resection procedure is more superior to the vaginal bridge repair suture for improvement of obstructed defecation syndrome from rectocele, however, it has a higher cost and some patient with reversible slight anal incontinence after surgery.
