测量指标:

Outcomes:

指标中文名:

息肉不完整切除率

指标类型:

主要指标

Outcome:

Incomplete polyp removal rate

Type:

Primary indicator

测量时间点:

测量方法:

所有息肉切除术后,对创面边缘的4个象限及创面基底部各取一块活检,每个部位单独送病检,如果任意一块活检组织发现息肉残留,则视为不完整切除

Measure time point of outcome:

Measure method:

After all polyps were excised, one biopsy was taken from each of the four quadrants at the edge of the wound and the base of the wound, and each site was sent for examination separately. If polyps remained in any biopsy tissue, the resection was considered incomplete

指标中文名:

息肉复发率

指标类型:

次要指标

Outcome:

Polyp recurrence rate

Type:

Secondary indicator

测量时间点:

测量方法:

息肉切除术后,在12月内进行结肠镜监测检查,内镜下拍照留图,若怀疑复发则进行活检或再次圈套器冷切除并送病理检查,如果病理同前次息肉性质,则视为复发

Measure time point of outcome:

Measure method:

After polyp resection, colonoscopy monitoring was performed within 12 months, and pictures were taken under the endoscope. If recurrence was suspected, biopsy or cold snare resection was performed again and pathological examination was sent. If the pathology was the same as the previous polyp, recurrence was considered

指标中文名:

整块切除率

指标类型:

次要指标

Outcome:

Monolithic removal rate

Type:

Secondary indicator

测量时间点:

测量方法:

内镜下一次性整块切除病变视为整块切除

Measure time point of outcome:

Measure method:

Endoscopic lump-sum resection is considered as lump-sum resection

指标中文名:

息肉切除时间

指标类型:

次要指标

Outcome:

Polypectomy time

Type:

Secondary indicator

测量时间点:

测量方法:

从圈套器(CSP组)或注射针(SI-CSP组)插入到达病变处开始计时开始(同时拍照留图),到息肉切除计时结束(同时拍照流图),此为1枚息肉切除时间

Measure time point of outcome:

Measure time point of outcome:

Measure method:

If bleeding occurs during the procedure and requires titanium clamp hemostasis, hot biopsy forceps or hemostatic forceps electrocoagulation and APC electrocoagulation, it is included in the intraoperative bleeding.
