背景情况:
- 结肠癌的生存率受到手术方法的影响.
- 腹腔镜切除术越来越多地被采用,需要与开放式切除术进行生存比较.
- 关于这些手术方法对I-III期结肠癌的比较有效性的证据正在演变.
研究的目的:
- 为了比较患有I-III期结肠癌,经过腹腔镜切除术的患者的5年总生存期与开放式切除术.
- 为了因果模型外科手术对长期生存结果的影响.
- 为指导临床决策提供证据,以确定腹腔镜切除术的安全性和有效性.
主要方法:
- 使用基于人口的癌症注册数据 (2008-2018) 模拟一个假设的III期,多中心,开放标签,两个并行臂试验.
- 应用一个逆概率加权的RoystonParmar参数生存模型 (RPpsm) 来估计危险比率和绝对风险差异.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
