Lateral lymphadenectomy in treatment of rectal carcinoma

Abstract

The aim of this work is to present existence of the lateral lymphatic spread of metastases in patients with Dukes C low rectal carcinoma (60 % of all patients), located at or bellow peritoneal reflexion. Prospective clinical investigation analyzed the group of 64 patients (32 underwent lateral lymphadenectomy and 32 didn?t), all treated at 1st Surgical Clinic, Clinical Center of Serbia. Lateral lymphatic spread of metastases was proven by frozen section in 8 cases, so extensive lateral lymphadenectomy was performed. In the group of patients who underwent lateral lymphadenectomy, positive lymph nodes were registered in 18 patients (56,2%); in group of patients operated without lateral lymphadenectomy, metastatic lymph nodes were registered in 12 patients (37,5%). According to results of this investigation, method of lateral lymphadenectomy, as well as extensive lateral lymphadenectomy, is significant for exact determination of postoperative stage of the disease. Also, there is a significant increase in number of patients with Dukes C stage of the disease. In those patients, mesorectectomy alone is not sufficient.
