[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 ulcers" >stasis ulcers occur as a result of insufficiency" >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 stasis" >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" >peptic ulcer.gastric ulcer an ulcer of the inner wall of the stomach, one of the two most common kinds of peptic ulcer" >peptic ulcer.Hunner's ulcer one involving all layers of the bladder wall, seen in cystitis" >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.

duodenal ulcer

A crater in the lining of the first part of the small intestine (the DUODENUM) usually caused by the action of strong acid and digestive enzymes coming from the stomach. Duodenal ulcer is also related to the presence of an organism Helicobacter pylori . Destruction of this organism with antibiotics, together with the use of proton pump inhibitor drugs such as OMEPRAZOLE (Losec), has been shown to cure many ulcers and to prevent recurrence. See also PEPTIC ULCER.

Patient discussion about duodenal ulcer

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 duodenum is right after the stomach. They are both (as published a few years back) caused 90% of the time from a bacteria named helicobacter pylori. Hence the treatment for it is probably antibiotics. But I guess that should be your doctor’s call. Good luck!
