Close-up clinical shot of duodenal ulcer
Numéro d’image : 11843451
| Clinical photograph of a large duodenal ulcer,taken following surgical resection (removal). The ulcer is the prominent triangular crater at centre,with a smooth,yellow base. The underlying cause of duodenal ulcers is obscure; destruction of the mucous membrane & underlying muscle layers in susceptible individuals is due to the action of acid & pepsin released from the stomach. Hypersecretion of gastric acid is not believed to be the only factor; cigarette smoking & aspirin- type drugs are also implicated. Healing is promoted by drugs that block the secretion of gastric acid. Ulcers in the stomach & duodenum are commonly called peptic ulcers | |
