Procedure time for gastric endoscopic submucosal dissection according to location, considering both sides of the mucosal circumferential incision and submucosal dissection ; retrospective study
- Conditions
- gastric neoplasm
- Registration Number
- JPRN-UMIN000022820
- Lead Sponsor
- Department of Gastroenterology, Juntendo University School of Medicine
- Brief Summary
The 12 locations were 1) lesions at the esophagogastric junction; 2) fornix; 3) lesser curvature of the gastric body; 4) greater curvature of the gastric body;5) anterior wall of the gastric body; 6) posterior wall of the gastric body; 7) lesion across the angle; 8) lesser curvature of the antrum; 9) greater curvature of the antrum;10) anterior wall of the antrum; 11) posterior wall of the antrum; and 12) lesion across from the pylorus ring. A significant difference was found in circumference incision speed (CIS) and submucosal dissection speed (SDS) for each location (p < 0.01), which demonstrates the validity of this classification system. In several locations, CIS and SDS were not consistent with each other.
