Efficacy of endoscopic submucosal dissection for gastrointestinal subepithelial tumors within the submucosa: multicenter study
- Conditions
- gastrointestinal subepithelial tumors within submucosa
- Registration Number
- JPRN-UMIN000011690
- Lead Sponsor
- Kagawa University Hospital
- Brief Summary
The rates of en bloc resection, curative resection, complications were 98.2%, 66.7%, 7.7% for overall (n=57), 100%, 61.9%, 2.4% for NET (n=42), and 93.3%, 80%, 20% for indeterminate SELs (n=15), respectively. The rates of curative resection were poor with 20% in stomach (n=5), 33% in duodenum (n=3), compared with 71% in rectum (n=24). Including conservative approach for 11 of 16 NETs who resulted in non-curative resection, no tumor recurrences occurred in all cases during follow-up period.
