What you are too afraid to ask about surgical anatomy of the stomach
– What is the criminal nerve of Grassi?
– What are the Lymph node stations of the stomach?
– How is the cardia irrigated?
To answer the questions
– What is the criminal nerve of Grassi?
It is the first branch of the posterior vagus nerve that gives innervation to the posterior wall of the gastric fundus.
– What are the lymph node stations of the stomach?
Lymph node stations are described in this class: there are 20 groups in the abdominal area that are divided into regional lymph nodes and metastatic lymph nodes, and 3 groups in the thoracic region (110, 111 and 112).
– How is the cardia irrigated?
The cardia is irrigated by the anterior and posterior cardioesophageal arteries (also called anterior and posterior gastric arteries) and by branches of the lower diaphragmatic artery.
