干预措施:

Interventions:

组别:

冷圈套器切除术组 (CSP组)

样本量:

117

Group:

Cold trap resection group (CSP group)

Sample size:

干预措施:

使用常规圈套器套取病灶及周边1-3mm正常黏膜组织,不抬离肠壁继续收缩圈套器,进行机械切除套取组织

干预措施代码:

Intervention:

Use a conventional snare to extract the lesion and 1-3mm of normal mucosal tissue around it. Without lifting it away from the intestinal wall, continue to contract the snare and perform mechanical resection to extract the tissue

Intervention code:

组别:

冷内镜黏膜切除术组 (CEMR组)

样本量:

117

Group:

Cold endoscopic mucosal resection group (CEMR group)

Sample size:

干预措施:

使用注射针黏膜下注射生理盐水+靛胭脂混合液,病灶充分抬举后,使用常规圈套器套取病灶及周边1-3mm正常黏膜组织,不抬离肠壁继续收缩圈套器,进行机械切除套取组织。

干预措施代码:

Intervention:

A mixture of normal saline and carmine was injected submucosa with an injection needle. After the lesion was fully lifted, a conventional snare was used to extract the lesion and the surrounding 1-3mm normal mucosal tissue. The snare was continued to contract without lifting the intestinal wall, and mechanical resection was performed to extract the tissue.

指标中文名:

标本的切除深度

指标类型:

主要指标

Outcome:

Depth of specimen resection

Type:

Primary indicator

测量时间点:

术后标本平铺展开使标本黏膜层贴附于滤纸上,固定于10%福尔马林液中,完成脱水、石蜡包埋、切片、染色后方可测量

测量方法:

切除术后标本是否包含的黏膜肌层(MM)和/或粘膜下层(SM)组织。当标本包含SM组织,则测量自MM至底切缘的深度

Measure time point of outcome:

The postoperative specimen is laid flat and spread out, with the mucosal layer adhered to filter pap

Measure method:

Whether the post-resection specimen includes mucosal muscle layer (MM) and/or submucosal layer (SM) tissue. When the specimen includes SM tissue, measure the depth from the MM to the deepest resection margin.

指标类型:

次要指标

Outcome:

Immediate postoperative bleeding and delayed bleeding

Type:

Secondary indicator

测量时间点:

术后即刻观察及住院期间观察

测量方法:

Measure time point of outcome:

Immediate postoperative observation and inpatient observation

Measure method:

Intraoperative immediate bleeding refers to bleeding during surgery that persists for more than 30 seconds and requires endoscopic intervention . Postoperative delayed bleeding refers to bleeding that occurs during the postoperative hospital stay and requires endoscopic intervention.
