A peptic ulcer is a defect in the inner lining of the stomach or duodenum typically due to excessive stomach acid. Extension of the ulcer through the lining of the digestive tract results in spillage of the stomach or intestinal contents into the abdominal cavity, leading to an acute chemical peritonitis.
The ulcer is known initially as a peptic ulcer before the ulcer burns through the full thickness of the stomach or duodenal wall. A diagnosis is made by taking an erect abdominal/chest X-ray (seeking air under the diaphragm). This is in fact one of the very few occasions in modern times where surgery is undertaken to treat an ulcer. [3]

An ulcer is a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Ulcers are most common on the skin of the lower extremities and in the gastrointestinal tract. An ulcer that appears on the skin is ...
Superficial ulcers involve a loss of part of the epithelium. Deep ulcers extend into or through the stroma and can result in severe scarring and corneal perforation. Descemetoceles occur when the ulcer extends through the stroma, exposing Descemet's membrane. This type of ulcer is especially dangerous and can result in perforation.
Marjolin's ulcer refers to an aggressive ulcerating squamous cell carcinoma presenting in an area of previously traumatized, [1] chronically inflamed, [2] or scarred skin. [3]: 737 [4] They are commonly present in the context of chronic wounds including burn injuries, varicose veins, venous ulcers, [5] ulcers from osteomyelitis, [6] and post radiotherapy scars.
Peptic ulcers are sores or defects that arise from tissue death, that develop in the mucosal lining of the stomach or duodenum. [7] When a peptic ulcer bursts, the gastrointestinal or duodenal fluid leaks through it and pools in the right paracolic gutter [ 2 ] which leads to inflammation of the peritoneum resulting in symptoms right lower ...
While dogs that have had gastropexies still may develop gas distension of the stomach, a significant reduction in recurrence of gastric volvulus is seen. Of 136 dogs that had surgery for gastric dilatation-volvulus, six that did have gastropexies had a recurrence, while 74 (54.5%) of those without the additional surgery recurred. [22]
