The evaluation of prone jackknife position sacral abdominal rectosigmoidectomy

侧方及周围组织浸润是低位直肠癌主要的增殖、发展方式,也是术后复发的主要因素。经骶尾、腹腔直肠乙状结肠切除术强调以会阴部强化局部控制为核心,是根据低位直肠癌的浸润及进展规律、复发方式所设计的一种手术方式。其优点为:视野充足、直视下深层解剖,精确切除导致复发的关键性的局部解剖学因素,并且实现了完全的全直肠系膜切除(TME)及必要的侧方淋巴结清扫。可降低局部复发率、改善存活率,是一种有效的外科治疗手段。

Lateral lymph node metastasis and surrounding tissue infiltration are main factors in the process of proliferation and development of lower rectal cancers, which also playing a critical role in the recurrence of lower rectal cancer after Miles surgery. SAR based on characters of proliferation, development, metastasis and recurrence of lower rectal cancer, which facilitated the possibility of an exact, sharp, and directly visualized removal of all structures critical to local recurrences of rectal cancer, and achieved the TME and optimal lateral lymph node dissection. SAR is an effective means in surgical treatment of lower rectal cancer, which effective reduces local recurrence and improve survival rates.
