UNASSIGNED: Endoscopic resection was performed for 133 superficial duodenal epithelial tumors from April 2017 to February 2022. Complete closure of mucosal defects after duodenal ESD was attempted for 82 superficial non-ampullary duodenal epithelial tumors, divided into OTSC and control (conventional clips used) groups. Closure outcomes were analyzed.
UNASSIGNED: The overall rate of complete mucosal defect closure in both groups was 98.8%. Significant between-group differences existed in the median estimated tumor size and median resected specimen area.
UNASSIGNED: Conventional clips work well for mucosal defects ≤18 mm after duodenal ESD, but for those >18 mm, a combination of OTSCs may be considered.
■于2017年4月至2022年2月对133例浅表十二指肠上皮肿瘤进行了内镜切除术。对82例浅表性非壶腹十二指肠上皮性肿瘤,尝试在十二指肠ESD后完全闭合粘膜缺损,分为OTSC和控制(使用常规剪辑)组。分析闭合结果。
■两组粘膜缺损完全闭合的总发生率为98.8%。中位估计肿瘤大小和中位切除标本面积存在显着组间差异。
■对于十二指肠ESD后≤18mm的粘膜缺损,常规夹子效果良好,但是对于那些>18毫米的,可以考虑OTSC的组合。
