ObjectiveTo explore the value of ultrasonography in the diagnosis of gastrointestinal stromal tumors (GISTs). MethodWe retrospectively analyzed the clinical data of 110 patients with surgical pathology confirmed GISTs between January 2008 and December 2013. All the patients underwent routine ultrasound examination. Thirty-two patients accepted oral contrast enhanced bowel ultrasonography, and 5 patients underwent trans-rectal ultrasound (TRUS). ResultsA total of 107 cases were detected out of the 110 cases of GISTs by ultrasonography, and the other three cases were missed. Among the 107 cases, 104 were shown to be masses, and 3 had thick gastric or intestinal walls. Among the 104 masses, hypo-echoic lesions were found in 73, heterogeneous lesions were found in 25, and hyper-echoic lesions were found in 6; 30 cases of tumor were less than 5 cm in diameter, 54 were between 5 cm to 10 cm in diameter, and 20 were longer than 10 cm in diameter (including 5 were longer than 20 cm in diameter). In the 107 cases, 12 were found to have liver metastasis, 4 were detected to have abdominal lymph node enlargement, and 3 had ascites. Surgery and pathological results showed that among the 110 cases of gastrointestinal stromal tumors, 91 developed from the stomach and intestine and the other 19 were extra-gastrointestinal stromal tumors; 72 were at high risk, 21medium risk, and 17 low risk. ConclusionsThe detection rate of GISTs by ultrasonography is high, but the quantitative and qualitative diagnosis ability should be raised.
ObjectiveTo evaluate the diagnostic value of ultrasound for gallbladder carcinoma (GA), in order to improve the ability of early ultrasonic and clinical diagnosis of GA. MethodsWe analyzed and compared the clinical data and ultrasonic results of 42 GA cases confirmed by surgery and pathology between January 2008 and December 2013, and summarized the classification, ultrasonographic features, and diagnosis of GA. ResultsAmong the 42 cases, 25 were correctly diagnosed by ultrasound (59.5%), among which 9 were thick-wall type, 11 were protrusion type and 5 were solid type. Seventeen cases were misdiagnosed (40.5%). Pathological results showed 14 cases of highly-differentiated adenocarcinoma, 16 of moderately differentiaed adenocarcinoma, 9 of poorly-differentiated adenocarcinoma, 2 of squamous adenocarcinoma and 1 of neuroendocrine carcinoma. ConclusionUltrasound is the preferred method for the diagnosis of GA because of its convenience, although the diagnostic accuracy is still not good and more efforts should be done.
