QUINTERO, Sebastián; LOMBANA, Luis Jorge; JARAMILLO, Luis Fernando  and  RAMIREZ, Yuli Patricia. Use of lymphatic node clearance. rev. colomb. cir. [online]. 2008, vol.23, n.4, pp.210-216. ISSN 2011-7582.

Lymphatic node clearance is the technique that dissolves the emulsion and removes the color of the fat tissues for the easy identification of lymph node structures. By means of this technique it has been possible to identify up to 100% of the additional nodes in the study of colorectal cancer specimens.   This technique has had capital importance in the subgroup of patients having neoadjuvant chemotherapy, the one that poses greater difficulties in the pathology study. 94% of nodes identified by the clearance method were 5 mm or less in diameter. Change in staging occurred in 10% of the cases included in this pilot study.

Keywords : colonic neoplasms; rectal neoplasms; lymph node excision; diagnosis; colorectal surgery; laparotomy.
