ABSTRACT
The survival of patients undergoing liver resection for colorectal metastases is poor in the presence of extrahepatic disease. Therefore identification of periportal and celiac lymph node metastases is central to proper patient selection. In this study we examined the technique of intraoperative hepatic lymphatic mapping with isosulfan blue dye in humans. Intrahepatic dye injection was performed in patients undergoing surgical exploration for colorectal liver metastases. The location of all blue-stained lymphatics and lymph nodes was recorded. All stained and unstained lymph nodes were biopsied for pathologic examination. Thirteen intraoperative lymphatic mapping procedures were performed in 11 patients. A blue-stained lymphatic was visualized in 11 of 13 injections (85%). A blue lymph node was visualized in seven of 13 injections (54%). Three of the seven blue nodes (43%) were not detected by the surgeon before the mapping procedure. There were no complications associated with the intrahepatic dye injections. All biopsied lymph nodes were negative for metastatic tumor. We conclude that intraoperative hepatic lymphatic mapping with isosulfan blue dye is a simple, rapid, and safe technique in humans. It may serve as an adjunct to random lymph node biopsy for the identification of periportal and celiac nodal metastases before liver resection in patients with metastatic colorectal carcinoma.
