ulcer [ul´ser]

a local defect, or excavation of the surface of an organ or tissue, produced by sloughing of necrotic inflammatory tissue.

aphthous ulcer a small painful ulcer in the mouth, approximately 2 to 5 mm in diameter. It usually remains for five to seven days and heals within two weeks with no scarring.

chronic leg ulcer ulceration of the lower leg caused by peripheral vascular disease involving either arteries and arterioles or veins and venules of the affected limb. Arterial and venous ulcers are quite different and require different modes of treatment. Venous stasis ulcers occur as a result of venous insufficiency in the lower limb. The insufficiency is due to deep vein thrombosis and failure of the one-way valves that act during muscle contraction to prevent the backflow of blood. Chronic varicosities of the veins can also cause venous stasis.

Patient Care. Stasis ulcers are difficult to treat because impaired blood flow interferes with the normal healing process and prolongs repair. Patient care is concerned with preventing a superimposed infection in the ulcer, increasing blood flow in the deeper veins, and decreasing pressure within the superficial veins.

decubitus ulcer pressure ulcer.

duodenal ulcer an ulcer of the duodenum, one of the two most common types of peptic ulcer.

gastric ulcer an ulcer of the inner wall of the stomach, one of the two most common kinds of peptic ulcer.

Hunner's ulcer one involving all layers of the bladder wall, seen in interstitial cystitis.

hypertensive ischemic ulcer a manifestation of infarction of the skin due to arteriolar occlusion as part of a longstanding vascular disease, seen especially in women in late middle age, and presenting as a red painful plaque on the lower limb or ankle that later breaks down into a superficial ulcer surrounded by a zone of purpuric erythema.

marginal ulcer a peptic ulcer occurring at the margin of a surgical anastomosis of the stomach and small intestine or duodenum. Marginal ulcers are a frequent complication of surgical treatment for peptic ulcer; they are difficult to control medically and often require further surgery.

peptic ulcer see peptic ulcer.

perforating ulcer one that involves the entire thickness of an organ, creating an opening on both surfaces.

phagedenic ulcer

1. any of a group of conditions due to secondary bacterial invasion of a preexisting cutaneous lesion or the intact skin of an individual with impaired resistance as a result of a systemic disease, which is characterized by necrotic ulceration associated with prominent tissue destruction.

2. tropical phagedenic ulcer.

pressure ulcer see pressure ulcer.

rodent ulcer ulcerating basal cell carcinoma of the skin.

stasis ulcer ulceration on the ankle due to venous insufficiency and venous stasis.

stress ulcer a type of peptic ulcer, usually gastric, resulting from stress; possible predisposing factors include changes in the microcirculation of the gastric mucosa, increased permeability of the gastric mucosa barrier to H⁺, and impaired cell proliferation.

trophic ulcer one due to imperfect nutrition of the part.

tropical ulcer

1. a lesion of cutaneous leishmaniasis.

2. tropical phagedenic ulcer.

tropical phagedenic ulcer a chronic, painful phagedenic ulcer usually seen on the lower limbs of malnourished children in the tropics; the etiology is unknown, but spirochetes, fusiform bacilli, and other bacteria are often present in the developing lesion, and protein and vitamin deficiency with lowered resistance to infection may play a role in the etiology.

varicose ulcer an ulcer due to varicose veins.

venereal ulcer a nonspecific term referring to the formation of ulcers resembling chancre or chancroid about the external genitalia; there are both sexually transmitted and other types.

---

gastric

pertaining to, affecting, or originating in the stomach.

---

gastric acid

see gastric juice (below).

gastric atony

a large distended stomach lacking in tone as seen in a horse that is a windsucker and continuously swallows air. Predisposes to chronic indigestion.

gastric cicatricial contraction

in horses causes constriction of the stomach and subsequent dilatation of the dorsal sac.

gastric dilatation

see gastric dilatation colic.

gastric dilatation-displacement

see gastric dilatation-volvulus (below).

gastric dilatation-volvulus (GDV)

a syndrome of gastric dilatation leading to volvulus, seen most often in deep-chested, large breed dogs. The etiology is unclear, but aerophagia or overeating are important factors. Gastric hemorrhage and ulceration, hypotensive, hypovolemic shock, and severe electrolyte disturbances contribute to the high mortality. Surgical intervention is often required, cardiac dysrhythmias complicate recovery, and recurrences are common. Called also gastric dilatation-displacement, bloat.

gastric distention

in pigs commonly results in vomiting.

gastric edema

an accompaniment of edema in most organs in cases where edema is widespread; as a sole lesion is significant in the abomasum in cases of arsenic poisoning, ostertagiasis and in edema disease in pigs.

gastric emptying time

the time taken for the stomach to begin to empty of contents; demonstrated in contrast radiography. Delayed in gastric retention due to dysfunction of the pylorus, abnormalities of gastric motility, foreign bodies and systemic diseases.

gastric fluid

see gastric juice (below).

gastric folds

folds in the gastric mucosa and part of the submucosa oriented in the direction of the long axis of the stomach, as they are in the abomasum; they may be few and simple or numerous and tortuous, as in the dog.

gastric foreign body

occurs most commonly in dogs, causing vomiting. Occasionally it may pass into the small intestine, causing partial or complete obstruction with more severe signs of dehydration, shock, and sometimes perforation with peritonitis. A variety of objects may be swallowed, e.g. needles, balls, children's toys, bones, fish hooks and socks, to name a few.

gastric habronemiasis

see habronemiasis.

gastric hemorrhage

caused by gastric ulcer or foreign body. May cause sudden death due to exsanguination, as in pigs with esophagogastric ulcer, or anemia with melena.

gastric hormones

see gastrointestinal hormones.

gastric impaction

in horses fed a diet of coarse indigestible roughage; a cause of subacute colic.

gastric inhibitory polypeptide (GIP)

a tentative gut hormone secreted by the mucosa of the small intestine and playing a part in controlling gastric (inhibition) and intestinal (stimulation) secretion and insulin release (stimulation).

gastric intubation

see intubation.

gastric invagination

a technique for gastric resection in which areas of nonviable gastric wall are folded inward and the remainder sutured together so the necrotic tissue sloughs into the gastric lumen.

gastric juice

the secretion of glands in the walls of the stomach for use in digestion. Its essential ingredients are pepsin, an enzyme that breaks down proteins in food, and hydrochloric acid, which destroys bacteria and is of assistance in the digestive process.

gastric motility

varies between the three regions of the stomach, being most active in the antrum, has a basic slow wave motility and a capacity to increase in response to the fullness of the stomach and to decrease with a rise in acidity of the duodenal contents.

gastric mucosa

secretes pepsin (as pepsinogen), hydrochloric acid.

gastric neoplasia

includes adenocarcinoma, carcinoma, benign adenomatous polyps, leiomyomas, plasmacytoma, squamous cell carcinoma.

gastric outlet obstruction

see pyloric obstruction, pyloric outflow failure.

gastric peptidases

includes pepsin A, trypsin, chymotrypsin, elastase, carboxypeptidase A, carboxypeptidase B.

gastric perforation

in horses occurs secondarily to lesions of the stomach wall, especially squamous cell carcinoma; causes a local peritonitis, often with extension to the spleen.

gastric pits

multiple small depressions in the gastric area of the stomach; a gastric gland opens into the bottom of each pit.

gastric rotation

rotations of the stomach in the embryonic abdomen between its first appearance and its final disposition. In simple-stomached animals such as dogs two rotations are recognized, from the axial tube ventrally and to the left.

gastric rupture

causes sudden cessation of abdominal pain caused by distention; acute endotoxic shock and peracute, diffuse peritonitis kill the animal within a few hours.

gastric squamous-cell carcinoma

the commonest gastric neoplasm in horses. Seen usually in the advanced stages of anorexia and weight loss. Characterized by a fungating mass in the pars esophagea often with secondary implants locally, sometimes widespread in other organs.

gastric torsion

in sows, predisposed by large, sloppy meal and great excitement at feeding time leading to very fast eating. There is a short course with death due to shock and infarction of the stomach wall. See also gastric dilatation-volvulus (above).

gastric ulcer

an ulcer of the inner wall of the stomach. It occurs in all species at a low level but causes little disease. There is a high prevalence in horses racing and in training and is thought to result in impaired appetite. In horses, also caused by nonsteroidal anti-inflammatory drugs. Esophagogastric ulcer in pigs may reach epidemic proportions in some piggeries and cause serious mortalities due to blood loss. Called also gastric mucosal ulceration.

gastric venous infarction

gross lesions of bright red to dark red mucosa; occur in many septicemias, viremias and toxemias in horses and pigs.

gastric waves

peristaltic waves, the pacemakers for antral peristalsis.

gastric ulcer

A hole in gastric mucosa due to gastric secretions, related to H pylori in the mucosa, NSAIDs, cigarette smoking etc; the pain of a GU may not correlate with the severity of ulceration Diagnosis Barium x-ray, endoscopy Complications Bleeding, perforation, gastric obstruction

Patient discussion about gastric ulcer.

Q. Stomach ulcer or bad heartburn? hi. i am not sure if this is just heartburn or maybe i have an ulcer. for the last 7 months i have been getting really severe pains in my stomach (between my chest and my belly button). my upper back gets sharp pains and my stomach bloats out like I’m 8 months pregnant!!!. i have tried to take antacids for this but nothing works. i don’t know what else to do. it scares me sometimes because i have no idea what it is. My mom thinks it could be an ulcer. the pain lasts for a good 4 to 5 hours and i cant even sit down because the pain hurts so bad. can anyone tell me what this might be?????

A. After 7 months with an ulcer you’d be vomiting blood and may have blood in your feces. Anti acid would have helped. So what you say doesn’t sound anything like it. I think a good idea will be going the next morning to see a Dr. – looking for a diagnosis on the web is not a very good idea. And even if you know for certain that you have an ulcer- it is curable. Why wait 7 months?

Q. What is the difference between duodenal ulcer and stomach ulcer? I was diagnosed recently with duodenal ulcer. I heard the term stomach ulcer but not duodenal. What causes duodenal and what cause stomach ulcer? And how do they treat duodenal ulcer?

A. The location. Stomach ulcers are located in the stomach. Duodenal ulcers are located in the duodenum, which is the first part of the intestine (that have 3 parts) right after the stomach. The cause is ususal the same and so is the treatment- antibiotics. I got both. First time it was stomach ulcer and then duodenal. So I can tell you they are both very painful …:)

Q. what does it mean when it feels like theres something moving inside your stomach?

A. have you seen "alien" ?
just kidding- 99 out of a 100 it's your bowels..you see your digestive system always working, moving around stuff, expanding and shrinking, depends on what you give it. so maybe it's your bowel movements who alarms you.
