Abstract

Objectives: Determine the rate of the removed gastric submucosal tumors. Subjects and methods: Select the entire sample prospective and retrospective, cross-sectional descriptive study on 110 patients with gastric submucosal tumors at the Bach Mai Hospital from September 2021 to August 2023. Results: The average age is 52.7 ± 14.5 years old, and the male/female ratio is 1/1.5. Most patients have no clinical symptoms and are discovered incidentally through gastric endoscopy (43.6%). Tumor location is in the body of the stomach (50.8%). The average size is 4.15±2.5cm, mainly 2-5 cm (47.3%). On upper gastrointestinal endoscopy images, submucosal tumors are often raised lesions with smooth surfaces (70%). Regarding the histopathological type of tumor, GIST accounts for 67.3%. Ectopic pancreas, leiomyoma, and schwannoma account for 8.2%, 7.3%, and 6.4%, respectively. 4.5% of tumors are inflammatory fibrous polyps. Glomus tumors and lipomas account for 2.7%. There was 1 case of a gastric submucosal tumor that was metastatic HCC, accounting for 0.9% of the total samples in the study. A close positive linear correlation exists between the actual tumor size on the specimen after tumor resection and the estimated tumor size on conventional endoscopy. Conclusions: GIST were 67.3%, Ectopic pancreas were 8.2%, leiomyoma were 7.3%, Glomus tumors and lipomas account for 2.7%.
