Lymph node recurrence after right colon resection for cancer: evidence for the utilisation of complete mesocolic excision.

Complete mesocolic excision (CME) of colon cancer is a resection performed along embryological planes to include the completely intact mesentery surrounding the tumour with a high central vascular ligation. The aim is to remove all lymph nodes draining the cancer. Proponents of the technique cite the significantly decreased local recurrence and improved 5-year survival rates associated with CME versus conventional colectomy. Although increasingly performed in many centres, it has not yet gained widespread acceptance as it is technically more challenging and can incur an increased bleeding risk. A man in his 80s underwent a conventional right hemicolectomy for a pT4aN2aM0 ascending colon cancer at another institution. This was followed by chemotherapy. He presented to our institution 2 years later with an isolated 3.7×3.2 cm mesenteric tumour adjacent to his anastomosis. There was no intraluminal recurrence. He then underwent a repeat extended right colectomy with CME. Pathology confirmed lymph node recurrence. His case demonstrates the importance of CME in reducing carcinoma recurrence risk.
