Abstract
Background: Diagnosis of gastrointestinal submucosal tumors (SMT) is still a challenge in clinical practice and data about gastrointestinal submucosal tumors in our country was very limited. This study aimed to assess some characteristics of gastrointestinal submucosal tumors. Patients and Methods: cross–sectional study; 195 patients having gastrointestinal submucosal tumors diagnosed by endoscopic ultrasound at Hue University of Medicine and Pharmacy Hospital were enrolled from October 2013 to December 2018. Cutting biopsy or EUS- FNA in case necessary. Results: The mean age of patients was 48.92 ± 15.23. The prevalence was nearly equal in men and women with 48.2% and 51.8%, respectively. According to location, submucosal tumors were 45.6% in the stomach, 35.9% in the esophagus and 2.6% in the colon and rectum. According to etiology, the submucosal cyst was found in 23.6%, the leiomyoma was 22.1%, the Brunner’s gland was 1% and the unknown submucosal tumors was 19.5%. 58.1% of the leiomyoma and 67.4% of the submucosal cyst were found in the esophagus. 76% of the GIST, 83.3% of the ectopic pancreas and 64.7% of the lipoma were found in stomach. Conclusions: Based on endoscopy ultrasound, the most common locations of SMT were stomach and esophagus; the most common SMT were submucosal cyst and leiomyoma. Key words: Submucosal tumor (SMT), Endoscopic ultrasound (EUS)
