Benign tumors are leiomyomas, lipomas, neurofibromas, and fibromas. All these can abdominal bloating, pain, bleeding, diarrhea and – if an obstruction developed – cause vomiting. Polyps do not occur as frequently as in the colon.
Small bowel tumors represent 1-5% of all tumors of the gastrointestinal tract (around 9000 cases annually in the US). Benign tumors are leiomyomas, lipomas, neurofibromas, and fibromas. All these can abdominal bloating, pain, bleeding, diarrhea and – if an obstruction developed – cause vomiting. Polyps do not occur as frequently as in the colon. Adenocarcinoma, a malignant tumor is rare. Usually it occurs in the duodenum or proximal jejunum and causes minimal discomfort. In patients with Crohn’s disease, the tumors tend to occur distally in the bypassed or inflamed loops of intestine; adenocarcinoma is more common in Crohn’s disease of the small intestine than in the colon. Primary malignant lymphoma (lymphoma at a Glance), which occur in the ileum can cause a long stiffened segment. Small intestine lymphomas often occur with long untreated celiac disease. Carcinoid tumors (overview of carcinoid tumors) usually occur in the small intestine, v. a. in the ileum and appendix and are often malignant in these locations. In 50% of cases, multiple tumors occur. Of the tumors> 2 cm in diameter are 80% metastasized or local hepatic at the time of surgery. About 30% of Dünndarmkarzinoide cause obstruction, pain, bleeding, or carcinoid syndrome. The therapy is surgical resection; it may require repeated surgery. Kaposi’s sarcoma (Kaposi’s sarcoma), first described as a disease of older men of Jewish and Italian, occurs in an aggressive form in Africans, organ donation recipients and AIDS patients, who have an infestation of the GIT to 40-60%. The lesions can occur anywhere in the GIT, but are commonly found in the stomach, small intestine, or distal colon. Gastrointestinal lesions are usually asymptomatic, but bleeding, diarrhea, protein-losing enteropathy, and intussusception can occur. A second primary intestinal cancer occurs 20% of patients at ?; usually is lymphocytic leukemia, non-Hodgkin’s lymphoma, Hodgkin’s lymphoma or adenocarcinoma of the GIT. The therapy depends on the cell type depends on the location and extent of the disease. Diagnosis enteroclysis Occasionally endoscopy or capsule video endoscopy enteroclysis (. Translator’s note .: double contrast X-ray examination of the small intestine.), Possibly CT enteroclysis – X-ray and other imaging contrast examinations, is probably the most common examination of uncontrollable growth in the small intestine. A small intestine endoscopy by means of enteroscopy can be used to represent tumors and to biopsy. A video capsule endoscopy (endoscopy, video capsule endoscopy) can help small bowel lesions, v. a. to identify sources of bleeding; it transmits a swallowed capsule 2 frames / s to an external recorder. The original capsule is not usable in the stomach or colon, as it turns over in these larger hollow organs. A Kolonkapselkamera with better optics and illumination for use in larger hollow organs located in the DEVELOPMENT. Therapy Surgical resection Treatment consists of resection. Electrocautery, Thermocoagulation or laser phototherapy during enteroscopy or surgery may be alternatives to resection.
