This is a timeline of gastroenterology, attempting to describe significant events in the development of the field. Advances in endoscopy are largely described.

Big picture

Time period Development summary
17th century The first scientific studies of the digestive system are performed by Jan Baptist van Helmont.[1]
19th century A major advance in treatment in the 19th century is the use of gastric lavage (washing out of the stomach) to treat stomach poisoning; this becomes a standard treatment for all forms of gastric irritation, and the long tube used to introduce the lavage fluid is also adapted to view the stomach for diagnostic use.[1] The late century sees rapid advances in the understanding of the physiology and biochemistry of the digestive tract.[2]
1960s Societies of endoscopy become widely established and provided, for persons in gastroenterology training, courses in the appropriate indications for endoscopic investigation and formal teaching of the techniques involved.[3]
20th century In the 1960s and 1970s, advancements are made with endoscope lenght, improved visualization, and greater control.[4] Since the 1970s, endoscopy starts becomming the incontrovertible tool of gastroenterology.[3]
