Background: Preoperative pathologic diagnosis of a subepithealial tumor(SET) may improve clinical decision making. The aim of this study was to evaluate diagnostic yield and the safety of ESD technique biopsy for patients with SETs. Methods: A total of 37 cases of SETs with both EUS and ESD technique biopsy were compared retrospectively. Results: The diagnostic yield of deep biopsy for the diagnosis was 91.9% (34 with diagnostic cytology; 3 with non diagnostic cytology). The mean long diameter of the 34 SET measured EUS was 20mm (range 10-40mm). Of these SETs, 17 (50%) were less than 20mm in size. The clinical diagnosis according to EUS findings was GIST in 22 cases. Of these cases, the histologic findings were as follows: 10(45.5%) benign lesion (5 ectopic pancreas, 4 leiomyoma, 1 lipoma), 9 (40.9%) GIST, 2 (9%) other cancer (1 lymphoepithelial cancer, 1 adenocarcinoma), 1 (4.6%) non diagnostic cytology. There were no complications such as bleeding or perforation during or after the procedures. Conclusion: Diagnostic yield of ESD technique biopsy was relatively high in patients with SETs and was also useful in the diagnosis in the small size lesion (less than 20mm). Because of this, this method also would be able to reduce the need for unnecessary surgery. |
