RT Journal Article SR Electronic T1 Laterally extended parametrectomy (LEP), the technique for radical pelvic side wall dissection: Feasibility, technique and results JF International Journal of Gynecologic Cancer JO Int J Gynecol Cancer FD BMJ Publishing Group Ltd SP 914 OP 917 DO 10.1136/ijgc-00009577-200311000-00030 VO 13 IS 6 A1 LÁSZLÓ PÁLFALVI A1 László Ungár YR 2003 UL http://ijgc.bmj.com/content/13/6/914.abstract AB A new surgical method was introduced for the treatment of Ib lymph node positive and IIb cervical cancer patients. The lateral resection plane corresponds to the true pelvic side wall, the plane represented by the internal obturator muscle, the linea arcuata, and the piriformis muscle with the convergent branches of the sacral plexus. The LEP procedure overcomes the limitations of the standard class III-IV radical hysterectomy, which leaves in situ the gluteal superior, inferior and pudendal nodes, thus improving local control and survival.
