Gastroenterology is the branch of medicine focused on the digestive system and its disorders.
Diseases affecting the gastrointestinal tract, which include the organs from the mouth into the anus, along with the alimentary canal, are the focus of this speciality. Physicians practising in this field are called gastroenterologists.
They have usually completed about eight years of pre-medical and medical education, a year-long internship (if this is not a part of the residency), three years of an internal medicine residency, and two to three years in the gastroenterology fellowship.
Gastroenterologists perform a number of diagnostic and therapeutic procedures including colonoscopy, endoscopy, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound and liver biopsy.
Some gastroenterology trainees will complete a “fourth-year” (although this is often their seventh year of graduate medical education) in transplant hepatology, advanced endoscopy, inflammatory bowel disease, motility or other topics.
Hepatology, or hepatobiliary medicine, encompasses the study of the liver, pancreas, and biliary tree, while proctology encompasses the fields of anus and rectum diseases. They are traditionally considered sub-specialities of
Citing from Egyptian papyri, John F. Nunn identified significant knowledge of gastrointestinal diseases among practising physicians during the periods of the pharaohs. Irynakhty, of the tenth dynasty, c. 2125 B.C., was a court physician specializing in gastroenterology, sleeping, and proctology.
Among ancient Greeks, Hippocrates attributed digestion to the concoction. Galen’s concept of the stomach having four faculties was widely accepted up to modernity in the seventeenth century.
Italian Lazzaro Spallanzani (1729–99) was among early physicians to disregard Galen’s theories, and in 1780 he gave experimental proof on the action of gastric juice on foodstuffs.
In 1767, German Johann von Zimmermann wrote an important work on dysentery.
In 1777, Maximilian Stoll of Vienna described cancer of the gallbladder.
