Preliminary opinion on assessment categories of stomach ultrasound report and data system (Su-RADS)

Abstract

ObjectiveTransabdominal ultrasound after oral administration of an echoic cellulose-based gastric ultrasound contrast agent (TUS-OCCA) has recently been suggested as a valuable mass-screening tool for gastric cancer. The aim of this study was to propose a producible stomach ultrasound reporting and data system (Su-RADS) using TUS-OCCA for gastric cancer screening.PatientsThe study includes information of 2738 patients who underwent both gastroscopy and TUS-OCCA examinations recorded in software system. Gastroscopy examination with pathological diagnosis was considered as gold standard. Various gastric lesions were classified into category 1–5 based on gastric wall thicknesses of them (especially the mucosa layer).ResultsThe total malignant ratios of patients enrolled in this study were 17.1% (469/2738). The malignant ratios for category 1–5 were, respectively, 1.1, 1.7, 12.2, 34.2 and 78.1%. Category 2 indicated mild thickening of gastric wall at low risk for malignancy (1.7%); category 3 indicated moderate thickening at moderate risk for malignancy (12.2%); category 4 indicated severe thickening at high risk for malignancy (34.2%); category 5 indicated extremely severe thickening at extremely high risk for malignancy (78.1%). If category 2 was identified as cut-off point distinguishing between benign and malignant, the sensitivity and specificity by Su-RADS are 95.1 and 78.6%, respectively.ConclusionThe Su-RADS system could inform the physicians about key findings, indicating the risk for malignancy and necessity of additional gastroscopy examination. Prospectively randomly controlled study design with larger clinical trial is needed for further investigations.Electronic supplementary materialThe online version of this article (10.1007/s10120-018-0798-x) contains supplementary material, which is available to authorized users.

Evaluation of ultrasound-guided Freka-Trelumina enteral nutrition tube placement in the treatment of acute pancreatitis

“…With improvements in ultrasound techniques, transabdominal ultrasound has been used in the initial screening of gastric diseases for patients unwilling to undergo gastroscopy [18][19][20][21][22][23][24]. In the fasting state, the pylorus of most patients can be detected beneath the gallbladder neck by transabdominal ultrasound, which makes it possible to insert a feeding tube through the pylorus into the duodenum under the guidance of transabdominal ultrasound.…”
