EARLY EXPERIENCE OF ENDOSCOPIC SUBSEROSAL DISSECTION (ESSD) FOR GASTRIC TUMORS

Aims:

Most of gastric subepithelial tumors confined to submucosa can be resected by endoscopy. The endoscopic subtumorial resection for lesions originating from muscularis propria has been performed for the mass with submucosal or intramuscular growing only. Until now, the data for endoscopic subserosal dissection of gastric tumor was very rare.

Methods:

We analyzed to know the effectiveness of endoscopic subserosal resection (ESSD) in the gastric epithelial or subepithelial tumor with exophytic growing, retrospectively. ESSD was performed for 11 lesions, from August 2011 until May 2018. We wanted to evaluate about complete resection, procedure time and complication.

Results:

There were 3 male and 8 female, with mean age of 62.4 (51 – 72). Pathologic Diagnoses were 3 GISTs, 6 leiomyomas and 2 tubular adenomas with severe fibrosis. The site of lesions were gastric antrum in 2 and gastric body in 9. The mean size of resected specimens was 21 mm (12 – 36 mm). Mean procedure time was 36 min (11 – 72 min). En bloc resection rate was 11/11 (100%) and complete resection was achieved in 9/11 (82%). Perforation was occurred in 2 cases and managed conservatively.

Conclusions:

We think that Endoscopic subserosal dissection may be used as effective tool in the treatment of some gastric subepithelial tumor with subserosal or intramural growing. Further study is needed for evaluation for safety of ESSD.
