Özet
Aim: It is recently observed that there is not a remarkable advancement in gastrointestinal (GI) tract evaluations despite all developments in radiological imaging methods, and the high costs of examination, risk of radiation and difficult applicability in patients in modern CT methods emphasize the importance of ultrasonography (US) evaluations and stand US out as the scanning method in malignities of the GI tract. This study investigates the role of ultrasonography in cancers of the gastrointestinal tract, although the gold standard is known to be the endoscopy of the upper gastrointestinal tract or colonoscopy. Material and Method: The study included 40 patients whose ultrasonography and endoscopic examinations were planned with the preliminary diagnosis of tract malignity with findings of anamnesis and physical examination. All patients underwent ultrasonography and endoscopy, and results were compared with histopathologic diagnosis. Results: The study included a total of 40 patients, including 25 (62,5%) male and 15 (37,5%) female patients. Malignity was histopathologically identified in 15 (37,5%) patients. The sensitivity of ultrasound to identify cancers to the GI tract was 71,4%, its specificity was 75,7%, positive predictive value was 65,2%, and negative predictive value was 19,3%. The sensitivity of endoscopic intervention was 100%, its specificity was 96%, and positive predictive value was 93,7%. Discussion: Abdominal ultrasonography is a very specific and sensitive method in identification of gastric-colonic cancers. Therefore, we believe that the application of this non-invasive, easily accessible, cost-efficient method that does not involve radiation and entail risks before other diagnostic methods may be more helpful.
