Article Abstract

Lymph node (LN) retrieval is important for proper staging of colorectal carcinoma. Although various assistant techniques were recommended to facilitate LN identification, most of them were unavoidably time-consuming, resource intensive and costly. We prepared a modified GEWF solution (RE-GEWF) by use of recycled alcohol and a familiar dye, eosin and investigated its efficacy on 55 colorectal carcinoma specimens. Of the 55 studied cases, 33 of them with <12 LNs (Group A) and 22 with ≥12 LNs were detected (Group B) before RE-GEWF treatment. All were subsequently treated with RE-GEWF for 14-16h and were inspected again for LNs. The number of LNs revealed before and after RE-GEWF treatment was 539 and 476 respectively. The mean number of LNs per cases increased from 9.80±6.27 to 18.43±8.77. Twelve accessory LN metastases were found in 9 cases. Upgrade of pN stage was only present in 7 of the Group A cases. The results show that RE-GEWF is as effective as other reported LN revealing solutions. Use of RE-GEWF not only can assure the quality of LN detection, but also minimize the cost and reduce the release of waste.
