目的评估双吻合器吻合法在直肠癌保肛手术应用中的安全性和实用性。方法回顾总结４年中采用该技术行直肠癌手术９７例。癌灶下缘距肛缘平均距离８２ｃｍ，其中３～７ｃｍ４２例（４３３％，４２／９７），大于８ｃｍ５５例（５６７％，５５／９７）。结果所有患者吻合器切除圈完整。术后吻合口漏９例（９３％，９／９７），肿瘤距肛缘小于７ｃｍ患者的吻合口漏发生率显著高于距离大于７ｃｍ的患者（Ｐ＜０．０５），神经性膀胱排空障碍５例（５２％，５／９７），切口感染７例（７２％，７／９７），吻合口出血４例（４１％，４／９７），术后肛门部疼痛１例（１０％，１／９７）。结论双吻合器吻合法可作为低位直肠癌保肛手术的一种安全可靠的术式选择。 Objective To evaluate the safety and practicality of double stapler anastomosis in the application of anus-preserving rectal cancer. Methods A retrospective review was made of 97 patients who underwent rectal cancer surgery using this technique in 4 years. The average distance from the anal margin of the cancer foci was 82cm, of which 3~7cm were 42 cases (433%, 42/97) and more than 8cm were 55 cases (567%, 55/97). Results The stapler was completely removed in all patients. Postoperative anastomotic leakage occurred in 9 cases (93%, 9/97). The incidence of anastomotic leakage was significantly higher in patients with tumors less than 7cm from the anal margin than in patients with distances greater than 7cm (P<0.05). Neurogenic bladder Five patients had emptying disorder (52%, 5/97), 7 cases of wound infection (72%, 7/97), 4 cases of anastomotic bleeding (41%, 4/97), postoperative anus One case of pain (10%, 1/97). Conclusion The double stapler anastomosis can be used as a safe and reliable surgical method for sphincter preserving operation of low rectal cancer.
