Background and Objectives: Submucosal tumors are generally discovered accidentally. Endoscopic ultrasound is a valuable technique in the diagonsis and management of submucosal tumors, however, there is still little research about the role of endoscopic ultrasound in diagnosing this pathology in Viet Nam. The purpose of this study was to research about endoscopic ultrasound to support the diagnosis of submucosal tumors in the upper gastrointestinal tract. Subjects and methods: This is a cross sectional study on 76 patients were diagnosed submucosal tumors of the upper gastrointestinal tract by endoscopic ultrasound at the Gastrointestinal Endoscopy Center, Hue University of Medicine and Pharmacy Hospital from May 2017 to July 2019. Results: In 76 patients, epigastric pain was most common (57.9%), followed by nausea or vomiting (15.8%); and asymptomatic (39.5%). Submucosal tumors located in the stomach (44.7%), esophagus (40.8%) and duodenum (14.5%). The overlying mucosa: 88.2% with the smooth mucosa, 9.2% with the umbilication (9.2%) and 2.6% with the mucosal ulceration. Mean size was 14.6 ± 9.1 mm. The muscularis mucosa was 47.4%, the submucosa was 13.2%, the muscularis propria was 32.9%. 61.8% with hypoechoic; 5.3% with hyperechoic; 22.4% with anechoic and 10.5% with mixed echoic. 82.9% with homogeneous tumor and 17.1% with heterogeneous tumor. All tumors have a smooth margin. 5.3% with positive Doppler signal and 94.7% with negative Doppler signal. Conclusion: Endoscopic ultrasound can provide information about size, location, structure, margin, Doppler signal and this is a highly valuable technique in the diagnosis of submucosal tumors of the upper gastrointestinal tract.

Schwannomas are generally benign, slow growing tumors. They are rarely observed in the gastrointestinal tract with the most common site being the stomach. These tumors are usually asymptomatic. The preoperative diagnosis <em>via</em> endoscopy is a challenging issue due to the difficulty of differentiation from other submucosal tumors. A 54-year-old woman presented with epigastric pain persisting for the last 10 months. Upper endoscopy revealed an elevated submucosal mass of the gastric antrum. The overlying mucosa was normal. Biopsy specimens yielded only unspecific signs of mild inactive chronic inflammation. Endoscopic ultrasound examination noted a hypoechoic homogeneous mass lesion located in the gastric antrum. The mass appeared to arise from the muscularis propria, and there was no perigastric lymphadenopathy. A contrast-enhanced computed tomography scan identified a homogeneous round mass and arising from the antrum of the stomach. Submucosal tumor was suspected and surgical intervention was recommended. The patient underwent an elective laparoscopic partial gastrectomy. The histopathologic features and immunohistochemical-staining pattern were consistent with a benign gastric schwannoma. Our patient shows no recurrence with a follow-up of one year. The definitive diagnosis of gastric schwannomas requires immunohistochemical studies. Complete margin negative surgical resection, as in this case, is the curative treatment of choice. The clinical course is generally benign.

Objective: To study the diagnostic accuracy of microprobe endoscopic ultrasonography (mEUS) in the diagnosis of bulge of digestive tract, and to summarize and explore the characteristics of ultrasound images of gastrointestinal bulge in mEUS diagnosis, to comprehensively evaluate microprobe ultrasound. The ability of endoscope to diagnose gastrointestinal bulging lesions provides a certain clinical basis for later nursing. Methods: A retrospective analysis of 302 cases of gastrointestinal bulging cases underwent microprobe ultrasound endoscopy from November 2011 to December 2015. The diagnosis of all cases was confirmed by endoscopic pathology, surgical pathology or follow-up. Microprobes were compared. The diagnostic accuracy of the results of ultrasound endoscopy and traditional endoscopy. Results: A total of 302 patients underwent microprobe ultrasound endoscopy, including 274 upper gastrointestinal tract, 28 colorectal, 97 esophagi in upper gastrointestinal tract, 152 in stomach and 25 in duodenum. The coincidence rate of mEUS diagnosis of esophageal bulge lesions was 97.93% (95/97), and the coincidence rate of gastroscopy diagnosis was 68.04 (66/97). The coincidence rate of mEUS diagnosis in gastric elevated lesions was 94.07% (143/152), and the coincidence rate of gastroscopy diagnosis was 50.65% (77/152). Conclusion: Microprobe endoscopic ultrasound can clearly show the structure of each layer of the digestive tract wall, reflecting the origin of the lesion and the depth of infiltration. Therefore, it can make accurate diagnosis of most gastrointestinal bulging lesions.
