Article
Microscopic positive tumor margin does not increase the rate of recurrence in endoscopic resected gastric mesenchymal tumors compared to negative tumor margin
The endoscopic resection of gastrointestinal mesenchymal tumors (GIMTs) is widely accepted because of its minimal invasiveness. However, one major concern is the high rate of positive microscopic margins remai...
