Gastrointestinal endoscopy and laparoscopic general surgery have been significantly affected by the emergence of new techniques. These two disciplines share many similarities, including the use of sophisticated and expensive technologies. Their proper assessment is essential because they are developed amidst ever-decreasing health care budgets. Gastroenterologists and general surgeons must both participate in such evaluations and feel confident in interpreting pertinent published data. The present review uses a clinician's point of view with relevant examples to discuss the methodologies adopted in technology assessment and to highlight common pitfalls encountered in study design, patient selection, timing and selection of the study, blinding, and outcome measurement. Cost and statistical considerations, as well as ethical issues, are also reviewed in the context of technology assessment.
新技术的出现对胃肠内镜检查和腹腔镜普通外科产生了重大影响。这两个学科有许多相似之处，包括使用复杂且昂贵的技术。由于它们是在医疗保健预算不断减少的情况下发展起来的，因此对它们进行恰当评估至关重要。胃肠病学家和普通外科医生都必须参与此类评估，并对解读相关已发表数据充满信心。本综述从临床医生的角度，通过相关实例讨论技术评估中采用的方法，并强调在研究设计、患者选择、研究的时机和选择、盲法以及结果测量中遇到的常见陷阱。在技术评估的背景下，还对成本和统计考量以及伦理问题进行了综述。
