An early gastric cancer in the antrum
Early gastric cancer A gastric cancer where the malignany is confined to the mucosa or submucosa but not infiltrating the muscularis mucosae. This type of gastric cancer was intitially described in Japan, but is of course found in any country where endoscopies are made. Resection is curative and 5-year survival is very high. An early gastric cancer does not usually cause any symptoms and is usually found when upper endoscopy is made for another reason or in screening examinations.

EATL (Abbr) Enteropathy Associated T-cell Lymphoma, a severe complication of coeliac disease. A disease called Ulcerative jejunitis (or jejunoileitis) is probably the same or a very similar entity.

Ectopic pancreas
Ectopic pancreas Pancreatic tissue outside the normal pancreas. Ectopic pancreases can be found in the stomach, duodenum and ileum and they are not rare (found in autopsies from 0.6% to 15%). In the stomach it is primarily found in the prepyloric region along the greater curvature. A central mucosal repression is often seen at endoscopy. Ectopic pancreases do not usually cause any symptoms and pancreatic malignancy in an ectopic pancreas is extremely rare - about 10 cases have been describet in the medical litterature. Synonyms are aberrant pancreas, heterotopic pancreas or accessory pancreas.


Eder-Puestow bougies
Eder-Puestow bougie A device used for the dilatation of esophageal strictures. The Eder-Puestow bougies of increasing size are successively passed through the stricture under fluoroscopic control. The Eder-Puestow bougies are not often used nowadays, this technique has been replaces by inflatable balloons that can be used during upper endoscopy.

Endolimax nana A nonpathogenic amoeba (protozoa) commensing in the colon

Endometriosis Functioning endometrial tissue outside the uterus. Endometriosis can be found in up to 20% of menstruating women, and is most often located in the uterosacral ligaments, the retrovaginal septum and vesicouterine space.Endometriosis can be found almoust anywhere in the abdominal cavity, and when located in the bowel wall it can cause gastrointestinal bleeding. The main symptoms are lower abdominal pain, and this disease can cause intertility.

Endoscopic Retrograde Cholangio-Pancreaticography (ERCP), an endoscopic examination of the biliary system and pancreatic duct using X-ray. A small catheter is inserted through an endoscope into the common bile dict and/or the pancratic duct, and these are then filled with contrast and pictured by x-ray.

Engerix B Trademark for a recombinant hepatitis B vaccine, manufactured by the pharmaceutical company GlaxoSmithKline

Entamoeba coli A nonpathogenic amoeba with multinucleate cysts

Entamoeba gingivalis A nonpathogenic amoeba (protozoa) often associated with poor oral hygiene.

Entamoeba hartmanni A nonpathogenic amoeba (protozoa).

Entamoeba histolytica A protozoa most prevalent in Central and South America, India and Africa. Infection can cause invasive colitis, intestinal perforation, peritonitis and liver abscess. Many infected patients are asymptomatic or have only mild symptoms. Diagnosis is made by stool samples. A serologic test is nearly always positive in an infected patient with symptoms, especially if the patient has a liver abscess. Metronidazol is the drug most often used for the treatment of amebiasis.

Entamoeba polecki An amoeba (protozoa) infecting monkeys and pigs, nonpathogenic to humans.

Entero- Referring to the small bowel



Enteroanastomosis, also called enteroenterostomy, is a surgical anastomosis between two segments of the bowel. In connection with gastric resection of the Billroth II type an enteroanastomosis - an example of which is seen in these pictures - is often made in order to minimize the amount of bile reflux into the remnant stomach.

Pinworm in the Sigmoid Colon


Three pinworms seen by a videoendscope in the colon ascendens
Enterobius vermicularis, pinworm, is an intestinal roundworm endemic in both temperate and tropical regions and common especially in schoolage children. It is especially common in group living conditions. The pinworm can be found in the caecum and colon. Anal pruritus is the most common symtom, but the infection can be associated with abdominal pain. The adult female pinworm is about 10 millimeters long, the male pinworm is much smaller. The female worm lays eggs in the perianal region, and the worm is transmitted from person to person via the infected persons hands, or by bedclothes. Enterobius vermicularis can be treated with several antihelminthic drugs, e.g. pyrantel pamoate, pyrvinium pamoate or mebendazole.

Enterocolitis Inflammation affecting both the small and the large bowel.

Enteroenterostomy See Enteroanastomosis

Enteroglucagon A gastrointestinal hormone produced in the terminal ileum and colon. The main physiological effect is delaying of gastric emptying, besides that this hormone has a trophic effect on gut mucosa.

Enteropathy Associated T-cell Lymphoma (EATL) A severe complication of coeliac disease. A disease called Ulcerative jejunitis (or jejunoileitis) is probably the same or a very similar entity.

Epidemic A sudden large outbreak of an infectious disease rapidly spreading among the population. Influenza is nowadays the most common cause of an epidemic. An epidemic spreading in many countries is called a pandemic.

Erytema elevatum diutinum and coeliac disease

Erythema elevatum diutinum A very rare chronic skin disease causing typical red or brown papules on the back of the hands, buttocks, elbows and legs. This disease was first descibed by Hutchinson in 1888 and by Bury in the following year (and hence it is sometimes called Bury´s disease). It is a type of leukocytoclastic vasculitis the cause of which is unknown but it can be associated with rheumatologic or haematologic disorders or viral infections. A skin biopsy is needed for diagnosis. The disease can spontaneuously dissappear after 5 - 25 years. Dapsone is the drug most used in the treatment and is usually effective.. The disease can be associated with coeliac disease and can then be cured with a glutenfree diet.

Erythema necrolytica migrans A skin disease, usually starting from the perineal region, and a nearly pathognomic sign of an endocrine tumour in the pancreas, glucagonoma.


Erythema nodosum
Erythema nodosum An inflammatory reaction in the subcutaneous fat mainly on the legs causing multiple, tender and red nodules 1 to 3-5 cm in size. Active inflammatory bowel diseases (Crohn´s disease and ulcerative colitis ) are nowadays the main etiologic factor. Tuberculosis and sarcoidosis can cause erythema nodosum. This skin disease is treated with short courses of cortison and/or other anti-inflammatory agents.

Erythropoietin (EPO) A hormone secreted by the kidneys and the major regulator of erythorppoiesis. Lack of erythropoietin explains the anaemia often seen in kidney diseases. Since 1986 this hormon has been used in the treatment of severe anaemia of different causes.

Exanetide A new drug which mimics the effect of Glucagon-like peptide (GLP-1), one of the incretin-hormons that are secreted in the bowel wall and which stimulates insulin production in the pancreas beta cells, thus lowering blood glucose. Esanetide (trade mark Byetta) can be used in the treatment of type II diabetes mellitus - which, as it seems, is a disease where part of the pathogenesis is low secretion of GLP-1 in the bowel wall.


Drawing made by Georges Dieulafoy. a = artery, h = opening in the vessel wall
Exulceratio Simplex Dieulafoy A rare cause of massive gastrointestinal bleeding, usually in the stomach but can occur in the duodenum or the rest of the small bowel. The bleeding is caused by a ruptured artery. The bleeding is massive and mortality due to bleeding is significant. The lesion can be treated endoscopically when it is in the stomach or proximal duodenum. The first case report concering this disease was written by a French doctor, Georges Dieulafoy.

Ezetimibe A new drug which interferes with the absorption of cholesterol in the small bowel. This drug can thus be used in the treatment of patients with hypercholesterolemia.
