Small intestinal stromal tumors acccount for approximately 35% of all gastrointestinal stromal tumors. Gastrointestinal bleeding is considered as one of the main clinical symptoms for SISTs. Capsule endoscopy has brought revolution in small bowel diagnostics, as it is considered the best method of visualisation of the entire small intestine. Besides, it is well tolerated by patients and is accompanied by a low number of complications. It is also indicated as the first diagnostic method in gastrointestinal bleeding of obscure origin, following negative upper endoscopy and colonopcopy. Case report. 2 patients (a male and a female, aged 58 and 69, respectively) presented with obscure gastrointestinal bleeding have been examined by capsule endoscopy after negative upper endoscopy and colonoscopy. Videorecords have been assessed in both cases by two independent experts. The capsule reached the Bauchin-valve in both cases during the 8 hours of the testing time and the entire small bowel was clearly visible. - Based on the capsule endoscopic images, for one of the two cases a tumor has been reported as the background of the small intestinal bleeding. In the other case we could mark the location of the bleeding, while we were unable to ascertain the type of the actively bleeding lesion during the test. In order to determine the accurate bleeding source double-balloon enteroscopy was performed in the second case. After surgery the histological and immunhistochemical tests have justified the presence of spindle cell GISTs. Taking into consideration the Fletcher-classification, for the tumor size and the mitotic index, both cases can be classified as a GIST of low malignant potencial. Conclusions: An early diagnosis and application of a definitive therapy become possible by using capsule endoscopy, therefore the chance of survival of the patients might be increased.
