Digestive system surgery or gastro intestinal surgery, can be divided into upper GI surgery and lower GI surgery. Upper gastro intestinal surgery (upper GI surgery, like esophagus, stomach, duodenum and ileum) refers to a practice of surgery that focuses on the upper parts of the gastro intestinal tract. There are many operations relevant to the upper gastro intestinal tract that are best done only by those who keep constant practise, owing to their complexity.

Upper GI surgeons would have a focus in, and may exclusively perform, the following operations:

  • Pancreaticoduodenectomy
  • Esophagectomy
  • Liver resection

Lower gastro intestinal surgery surgery includes colorectal surgery as well as surgery of the small intestine. Academically, it refers to a sub-specialisation of medical practise whereby a general surgeon focuses on the lower gastro intestinal tract. A lower GI surgeon might specialise in the following operations:

  • Colectomy
  • Low or ultralow resections for rectal cancer, etc.
