BACKGROUND: Endoscopic submucosal dissection has technical limitations for the resection of gastric epithelial tumors with severe fibrosis and mixed or exophytic gastric subepithelial tumors (SETs).
AIMS: To analyze the safety and effectiveness of endoscopic subserosal dissection (ESSD) for tumors growing in the subserosal space.
METHODS: This observation study enrolled 18 patients who were diagnosed with gastric tumors and underwent ESSD at the Presbyterian Medical Center from 2010 to March 2019.
RESULTS: A total of 18 patients were treated by ESSD. The mean age of the patients was 61.7 years. The mean length of the long axis of the tumor was 18.0 ± 5.0 mm. The mean operation time was 44 (range 11-167) min. The pathologic diagnosis was leiomyoma in nine cases (50.0%), gastrointestinal stromal tumor in six (33.3%), low-grade adenoma with severe fibrosis in two (11.1%), and schwannoma in one (5.6%). There were three cases of perforation, which were treated conservatively. The complete resection rate was 94%, and local or systemic tumor recurrence was not seen in a mean 70 months of follow-up.
CONCLUSION: ESSD can be used for epithelial tumors with severe fibrosis and mixed or exophytic gastric SETs in the lesser curvature, cardia, or fundus that cannot be treated using standard methods.
