Utility of Colour Doppler Endoscopic Ultrasound Evaluation and Guided Therapy of Submucosal Tumours of the Upper Gastrointestinal Tract

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.

Abstract Background and study aims The optimal approach to small subepithelial tumors (SETs) of the upper gastrointestinal tract remains inconclusive. The aim of this study was to evaluate endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for less invasive tissue sampling of small SETs of the upper gastrointestinal tract. Patients and methods In this prospective observational study patients with small ( ≤ 3 cm) SETs of the upper gastrointestinal tract were eligible and underwent EUS-FNB with a 22-gauge core biopsy needle. The main outcome measure was the diagnostic yield. The number of obtained core biopsies was also assessed. Results Twenty patients were included. The mean SET size was 16 mm (range 10 – 27 mm). EUS-FNB was technically feasible in all cases and no complications were observed. The diagnostic yield was 75 %. Core biopsy specimens were obtained in only 25 % of cases. Conclusion EUS-FNB with a 22-gauge core biopsy needle of small SETs can achieve a definite diagnosis in the majority of cases. However, because core samples cannot regularly be obtained, EUS-FNB seems not to be convincingly superior to standard EUS-FNA in this setting
