قرحة الشدة (بالإنجليزية: stress ulcer) هو تآكل في الطبقة السطحية من بطانة المعدة والإثني عشر تصيب بعض المرضى الذين يتعرضون لحالات من المرض الشديد أو للعمليات الجراحية، أو للحوادث والحروق، ويطول بقاؤهم في وحدة العناية المركزة والمستشفيات. وقد تؤدي قرحة الشدة إلى حدوث نزيف بالجهاز الهضمي على شكل قيء دموي أو براز يحتوي على دم مهضوم. وتعالج قرحة الشدة بنفس علاج قرحة المعدة المزمنة. (ar) A stress ulcer is a single or multiple mucosal defect usually caused by physiological (not psychological) stress which can become complicated by upper gastrointestinal bleeding. This ulcers can be caused by shock, sepsis, trauma or other conditions and are found in patients with chronic illnesses. This ulcers are a significant issue in patients in critical and intensive care. It was previously thought that peptic ulcers (a different type of ulcer) could be caused by psychological stress but this was proven false with the discovery of Helicobacter pylori and its role in the formation of this ulcers. Stress ulcers are a different condition and are formed by different mechanisms. The term stress ulcer is a proper medical term and should not be misinterpreted as indicating that this ulcers are caused by emotional stress. Here the term stress refers to extreme physiological changes in the body. Another distinction between peptic and stress ulcers is their location in the upper gastrointestinal tract. Whereas ordinary peptic ulcers are found commonly in the gastric antrum and the duodenum, stress ulcers are usually found in the fundic mucosa and can be located anywhere within the stomach and proximal duodenum. Stress ulcers tend to present with multiple lesions whereas in peptic ulcers this much more uncommon. (en) |
