Anatomical terminology

The paraaortic lymph nodes (also known as para-aortic, periaortic, peri-aortic, and lumbar) are a group of lymph nodes that lie in front of the lumbar vertebral bodies near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs.

Divisions

The paraaortic lymph node group is divided into three subgroups: preaortic, retroaortic, and right and left lateral aortic.

• The preaortic group drains the abdominal part of the gastrointestinal tract above the mid-rectum.
• The retroaortic group drains from the lateral and preaortic glands.
• The lateral group drains the iliac lymph nodes, the ovaries, and other pelvic organs. The lateral group nodes are located adjacent to the aorta, anterior to the spine, extending laterally to the edge of the psoas major muscles, and superiorly to the crura of the diaphragm.

Dissection

When a paraaortic lymph node dissection or sampling is done as a part of the treatment of cancer, the lateral aortic lymph node group is the most important group. There are typically 15 to 20 lymph nodes on each side.

When dissected, the dissection usually includes the region from the bifurcation of the aorta to the superior mesenteric artery or the renal veins.

• When hepatic-side ductal margin is positive in N+ cases, additional resection of the bile duct is not necessary to render the negative hepatic-side ductal margin during surgery for extrahepatic distal bile duct carcinoma.

• Iso Y, Kita J, Kato M, Shimoda M, Kubota K.Author information Department of Gastroenterological Surgery, Dokkyo Medical University, Tochigi, Japan.AbstractBackground The current standard treatment for extrahepatic distal bile duct carcinoma (EDBDC) is surgical resection, as no effective alternative treatment exists. In this study, we investigated the treatment strategies and outcomes for 90 cases of EDBDC at our department. Material and Methods Between April 2000 and March 2013, 90 pancreatoduodenectomies (PDs) were performed for EDBDC. The mean patient age was 69.1±9.8 years, and there were 59 males and 31 females. Extended lymph adenectomy including lymph nodes around the common hepatic artery and celiac axis was performed in all patients. The mean operation time was 537.1±153.8 min and the mean operative blood loss was 814.0±494.0 ml. There were no operation-related deaths. The overall 1-, 3-, and 5-year survival rates were 90.0%, 51.2%, and 45.0%, respectively. Results Lymph node metastasis was present in 28 patients (N+; 31.1%), and it was absent in 62 (N-; 68.9%). The 5-year survival rate was 20.0% for N+ patients and 52.4% for N- patients, which is significantly higher (P=0.03). Nine cases (10.0%) showed hepatic-side ductal margin (HM) positivity for carcinoma. The 5-year survival rate was 18.7% for HM-positive patients and 48.3% for HM-negative patients, which is significantly higher (P=0.005). In multivariate analysis, N+ was the strongest adverse prognostic factor. Subclass analysis of 62 cases (excluding 28 N+ cases) revealed 7 patients with positive HMs (11.3%) and 55 patients with negative HMs (88.7%). The 5-year survival rate was 47.6% for HM-positive patients and 49.8% for HM-negative patients (P=0.73). Thirty-five cases (38.9%) recurred: there were 19 cases of local recurrence (21.1%), 11 cases of liver metastasis (12.2%), 4 cases of distant recurrence (4.4%), and 1 case of para-aortic lymph node metastasis (1.1%). Conclusions In conclusion, when HM is positive in N+ cases, additional resection of the bile duct is not necessary to render the HM negative for carcinoma.
