简要总结
The study aims to retrospectively investigate the endoscopic resection procedures of cancerous and precancerous lesions of the upper and lower digestive tract in order to evaluate the efficacy and safety outcomes and to compare different resection techniques. In particular, the resection techniques investigated will be mucosectomy, en bloc and piecemeal, endoscopic submucosal dissection (ESD) and its variants, full-thickness resection. The anatomical districts involved will be the esophagus, stomach, duodenum, colon and rectum.

结局指标
主要结局
recurrence rate
时间窗: one year
recurrence is the recurrence of the neoplasm at the resection site during follow-up
complete resection rate
时间窗: one month
the complete resection is the ability to remove the neoplasia with clear margins (R0)
en bloc resection rate
时间窗: one month
the en bloc resection is the ability to remove the neoplasia in a single piece
次要结局
- adverse events rate(one month)
- costs(one month)
