SMA lymph node dissectionSMV lymph node dissection
SMA lymph node dissection: The lymph node dissection boundary is on the left side of the superior mesenteric artery (SMA)
SMV lymph node dissection: The lymph node dissection boundary is on the left side of the superior mesenteric vein (SMV)
Study summary
The study was conducted on patients with advanced right-sided colon cancer, and the clinical pathological and prognostic data of the patients were compared between the two groups of patients who were randomly divided into those undergoing SMV and SMA left resection, with the aim of resolving the controversy over the left resection boundary of CME/D3 lymph node dissection through this study, and to clarify whether SMA left resection is superior to SMV left resection.
