This is the first time I post, I hope I can popularize some medical knowledge and make up for what is not taught in the textbook, and I hope everyone is healthy and happy!
First talk about a few concepts:
The understanding of clinical medicine can be roughly divided into: internal medicine, surgery, gynecology and pediatrics. Gynecology and pediatrics are very easy to understand, and you can understand it when you hear it. However, ordinary people are more likely to confuse the two concepts: medicine and surgery. From the perspective of English, it is easy to understand that internal medicine is treated by medicine, while surgery is treated by surgery.
Specialization is the inevitable development of medicine, so there are secondary and tertiary disciplines, and more detailed divisions are for better diagnosis and treatment.
Surgery is divided into: general surgery, cardiothoracic surgery, hepatobiliary surgery, urology, orthopedics, neurosurgery, burns, plastic surgery, microsurgery, etc.
General surgery includes a large class of diseases: abdominal surgery (gastrointestinal surgery, hepatobiliary surgery, pancreatic surgery, etc.), thyroid, hernia, etc.
To put it simply, gastrointestinal surgery is: diseases of the entire digestive tract from the stomach to the anus, including the stomach, duodenum, small intestine, large intestine and anus.
