目的探讨Ｍｉｌｅｓ手术骶前持续负压引流在临床上应用的可行性。方法对４７例低位直肠癌患者行Ｍｉｌｅｓ手术，不缝合盆底腹膜，Ⅰ期缝合会阴部切口，术后骶前引流持续负压吸引。结果会阴部伤口Ⅰ期愈合率达９１．４８％，未发生术后出血、肠梗阻。结论此方法能达到消灭残腔，充分引流，减少损伤，术后患者管理简便，减轻患者痛苦。
Objective To investigate the clinical feasibility of continuous negative pressure drainage before Miles operation. Methods Forty-seven patients with low rectal cancer underwent Miles operation. The pelvic floor peritoneum was not sutured. The perineal incision was sutured at the first stage. The preoperative drainage was sustained by negative pressure. Results The healing rate of the perineal wound was 91.48% at the first stage, and no postoperative bleeding or intestinal obstruction occurred. Conclusion This method can eliminate the residual cavity, drain adequately, and reduce injury. The management of postoperative patients is simple and the patient’s pain is relieved.
