Digestive system surgery, orgastrointestinal surgery, can be divided into upper GI surgery and lower GI surgery.[1]
Upper gastrointestinal surgery, often referred to asupper GI surgery, refers to a practise ofsurgery that focuses on the upper parts of thegastrointestinal tract. There are many operations relevant to the upper gastrointestinal tract that are best done only by those who keep constant practise, owing to their complexity. Consequently, ageneral surgeon may specialise in 'upper GI' by attempting to maintain currency in those skills.
Upper GI surgeons would have an interest in, and may exclusively perform, the following operations:
Lower gastrointestinal surgery includescolorectal surgery as well as surgery of thesmall intestine.
Academically, it refers to a sub-specialisation of medical practise whereby ageneral surgeon focuses on the lowergastrointestinal tract.
In the U.S., a student wanting to specialize and practice in adult lower GI surgery would generally have to go through four years of undergraduate college pre-medical education and get a bachelor's degree, then finish the four years of medical school, then finish a typically five-year-long residency in general surgery, and then perform a subsequent one-year-long (minimum) residency in surgery of the small intestine or large intestine (thecolon- specifically, thececum, thevermiform appendix, theascending colon, thetransverse colon, thehepatic flexure and thesplenic flexure, thedescending colon, and thesigmoid colon; and also therectum and theanus).
A fellowship (in surgery of the small intestine or of the large bowel, or in pediatric/neonatal lower GI surgery, or in surgery of congenital abnormalities or rare disorders of the lower GI tract, or in emergency/trauma surgery or in cancer surgery of the area), would add on approximately one to three more years.[2]
Alower GI surgeon might specialise in the following operations:
