'Gastroenterology' (
MeSH heading
[1] ) is the branch of
medicine where the
digestive system and its disorders are studied.
Etymologically it is the combination of
Ancient Greek words ''gastros'' (
stomach), ''enteron'' (
intestine) and ''
logos'' (
reason).
Diseases affecting
gastrointestinal tract (i.e.
organs from
mouth to
anus) are the focus of this speciality.
Doctors specialising in the field are called 'gastroenterologists'. Important advances are made in the last 50 years, contributing to rapid expansion of its scope.
'
Hepatology' or 'hepatobiliary medicine' encompasses the study of the
liver,
pancreas and
biliary tree and is traditionally considered a subspeciality.
History

Galen

Drawings of Bozzini's "Lichtleiter"
Citing from
Egyptian papyri, Nunn identified significant knowledge of gastrointestinal diseases among practising doctors in
Pharaoh periods. Irynakhty, of the tenth dynasty c. 2125
BC was a court
physician specialising in gastroenterology and
proctology.
[1]
Among ancient
Greeks,
Hippocrates attributed
digestion to concoction.
Galen's concept of the
stomach having four ''faculties'' was widely accepted up to modernity.
18th 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 Zimmermann wrote an important work on
dysentery.
★ In 1777
Maximilian de Stoll of
Vienna described cancer of the
gallbladder.
[2][3]
19th century:
★ In 1805
Philip Bozzini made first attempt to observe living human body through a tube he named ''Lichtleiter'' (light guiding instrument) to examine the
urinary tract, the
rectum and the
pharynx. This is the earliest description of
endoscopy.
[4][5]
★
Charles Emile Troisier described enlargement of
lymph node in abdominal cancer.
[6]
★ In 1868
Adolf Kussmaul, a well known German physician, developed the
gastroscope. He perfected the technique on
sword swallower.
★ In 1871, at the society of physicians in Vienna,
Carl Stoerk demonstrated an esophagoscope made of two telescopic metal tubes, initially devised by Waldenburg in 1870.
★ In 1876
Karl Wilhelm von Kupffer described the properties of some liver cells now called
Kupffer cell.
★ In 1884 Kronecker and Meltzern studied oesophageal
manometry in man.
20th century:
★
Rudolph Schindler described many important diseases involving digestive system during
World War I in his illustrated textbook and is portrayed by some as the "father of gastroscopy". He and Wolf developed a semiflexible gastroscope in 1932.
★ In 1932
Burrill Bernard Crohn described
Crohn's disease.
★ In 1957
Basil Hirschowitz introduced the first prototype fibreoptic gastroscope.
★ In 2005
Barry Marshall and
Robin Warren of Australia were awarded the
Nobel Prize in Physiology or Medicine for their discovery of ''
Helicobacter pylori'' (1982/1983) and its role in
peptic ulcer disease.
