A Gastrointestinal surgeon is one who is also called surgical gastroenterologist. His specialization focuses on everything that is concerned with the alimentary tract. Some of the complex tertiary level GI surgeries associated with pancreas, spleen, liver, and intestines including rectum are done by them.

Gastric bypass and other weight-loss surgeries make changes to your digestive system to help you lose weight by limiting how much you can eat or by reducing the absorption of nutrients, or both. Gastric bypass and other weight-loss surgeries are done when diet and exercise haven’t worked or when you have serious health problems because of your weight.

There are many types of weight-loss surgery, known collectively as bariatric surgery. Gastric bypass is one of the most common types of bariatric surgery in the United States. Many surgeons prefer gastric bypass surgery because it generally has fewer complications than do other weight-loss surgeries.

Still, all forms of weight-loss surgery, including gastric bypass, are major procedures that can pose serious risks and side effects. Also, you must make permanent healthy changes to your diet and get regular exercise to help ensure the long-term success of bariatric surgery.

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.
