Clinical value of endoscopic ultrasound in the diagnosis of minute gastric small stromal tumor / 中国基层医药

ABSTRACT

Objective To investigate the clinical value of endoscopic ultrasonography (EUS)on minute gas-tric stromal tumor (MGST).Methods 90 patients diagnosed with MGST were randomly divided into two groups. 45 patients in A group were given conventional endoscopic diagnosis,45 cases in B group were treated with endoscopic ultrasound diagnosis.After the two groups of patients with endoscopic treatment,the coincidence rate of preoperative diagnosis and pathological inspection test results was recorded,clinical features in MGST under EUS diagnosis were analyzed.Results All patients were diagnosed in the case of endoscopic surgery,endoscopic submucosal dissection (ESD)accounted for 94.44%,which was significantly higher than the use of endoscopic full -thickness resection (EFR)percentage of 5.56%,and the difference was statistically significant (χ2 =14.22,P <0.05);The two groups of patients after endoscopic treatment,were diagnosed as pathological inspection MGST.Preoperative diagnosis showed that EUS MGST suspected cases of 40 patients,conventional endoscopy MGST suspected cases of 31 cases.The diag-nosis coincidence rate of B group (88.89%)was significantly higher than that in A group (68.88%),the difference was statistically significant (χ2 =5.40,P <0.05);MGST of EUS images could be clearly observed in patients with tumor morphology,size,location,growth pattern,internal parenchyma,echo pattern,strengthening methods,the compo-sition ratio in line with the results of endoscopic treatment,diagnosis results in line with the pathological diagnosis. Conclusion EUS has significant value for the diagnosis of MGST,it has advantages in the clinical guidance and treatment.
