Anatomic study of the lymph nodes of the mesorectum

Abstract: The mean number of lymph nodes found in the mesorectum distal to the superior rectal artery division was 8.4. Most of these lymph nodes were proximal to the peritoneal reflection. The range found in the number of lymph nodes per case should be considered for use in the formulation of guidelines in anatomicopathologic studies of surgical specimens obtained after mesorectal excision.

“…The mesorectum, defined as the lymphovascular fatty tissue lying around the rectal wall, is recognized to be the main site of rectal tumour spread because of the absence of anatomical borders. The majority of mesorectal nodes seem to lie along the sigmoid rectal artery and its branches and the patterns of spread are related to the tumour position in the rectal wall [21,22].…”

“…Malignitelerde, bölgesel lenf nodu tutulumu en önemli prognostik faktörlerden biri olarak kabul edilmektedir. Hastalar arasında mezenterik lenf nodlarının dağılım ve sayıları geniş biyolojik varyasyonlar gösterebilmektedir (19). Eğer cerrahi teknikte ve patolojik değerlendirmede yetersizlik yoksa lenf nodu sayısı immünolojik cevabın göstergesi olabilir (20).…”

“…O número de LN estudados sofre interferência de fatores interdependentes, tais como: localização e características histopatológicas do tumor, aspectos inerentes ao paciente, propósito do procedimento (curativo ou paliativo), número de lesões, anatomia vascular de cada segmento (8,20) e do tratamento dispensado aos LN tanto cirúrgico, quanto anatomopatológico (4,10,17) . Na presente casuística, o número de LN dissecados (acometidos ou não) foi maior do que em outros estudos (4,19,30,32) , demonstrando a qualidade da ressecção cirúrgica e dissecção no Serviço.…”

“…A resposta linfocítica peritumoral apresentou correlação negativa com o número total de LN acometidos (P = 0,03). fração restante ou por características inerentes a cada segmento colônico (8) e à extensão da cirurgia. O comprometimento exclusivo de LN não-peritumorais é raro.…”
