目的 初步探讨采用单孔三通道法联合传统腹腔镜手术器械行单孔腔镜下附件手术的可行性与安全性。方法 回顾分 析2017年10月～2017年12月重庆医科大学附属第二医院妇科采用单孔三通道法联合传统腹腔镜手术器械行单孔腔镜 下附件手术的4例患者的临床资料。均经脐孔上缘行半环形切口长约2.0cm，采用单孔三通道法进行穿刺，置入传统 腹腔镜及手术器械实施手术。结果 4例手术均获得成功，术中未增加其它穿刺通道，均未中转开腹，患者术后均无 发热，术后4～5d出院，均无感染、脐疝、出血及伤口愈合不良等并发症发生。结论 ①针对具有实施传统腹腔镜附 件手术能力的医疗单位，选择合适的病例，采用单孔三通道法联合传统腔镜器械行单孔腔镜附件手术是一种安全可 行、微创且美容的手术方式；②盆腔子宫内膜异位症、卵巢子宫内膜异位囊肿的治疗也可采用此手术方式，但手术 难度相应增大。

Objective We present our initial experience with laparoendoscopic single-site surgery(LESS) by three-channel single port through a trans-umbilical access for adnexal tumors and report on the safety and feasibility of this technique. Methods A retrospective analysis was performed of 4 patients from October 2017 to December 2017 who underwent adnexal surgeries through LESS procedure by three-channel single port combined with the conventional laparoscopic instruments.LESS was performed by using a single port with triple-channel inserted method through a solitary 2.0 cm upper umbilicus incision and conventional laparoscopic instruments. Results All of the 4 patients had LESS surgeries successfully. No additional trocar required, no conversion to laparotomy happened. The operation incision scars of the 4 patients all healed well and were not obvious. The patients were discharged within 4-5 days after procedure without complications such as post-operative fever, umbilical hernia, hemorrhage or infection. Conclusion (1)With the strict precondition of indication, LESS using single port with triple-channel inserted method and conventional laparoscopic instruments can be a promisingly safe, minimally invasive and cosmetic approach to adnexal surgery.(2) Such technique can be used in therapy for pelvic endometriosis or ovarian endometriosis cyst, which may be more difficult.
