We investigated physician beliefs and behaviors regarding diminutive colorectal polyps and the contribution of these beliefs to variable detection rates.
One hundred sixty-seven members of the American College of Gastroenterology took a Web-based survey. We compared respondents and nonrespondents using demographic and practice information from the American Medical Association Physician Masterfile.
Respondents varied in their definition of diminutive polyps. Respondents acknowledged leaving diminutive polyps in place during colonoscopy in various scenarios. Years in practice, confidence in endoscopic histologic diagnosis, and never having seen advanced histology in a diminutive polyp were predictive of leaving polyps in place. The majority of respondents were at least somewhat agreeable to leaving diminutive polyps in place if guidelines endorsed this practice.
Gastroenterologists vary in their removal of diminutive polyps. The results have implications for the interpretation and management of variable polyp detection rates.
我们调查了医生对微小结直肠息肉的信念和行为，以及这些信念对可变检测率的贡献。
167 名美国胃肠病学会成员参加了一项基于网络的调查。我们使用美国医学协会医师主文件中的人口统计学和实践信息比较了应答者和非应答者。
应答者对微小息肉的定义存在差异。应答者承认在各种情况下在结肠镜检查中保留微小息肉。执业年限、对内镜组织学诊断的信心以及从未在微小息肉中见到过高级组织学是决定将息肉留在原位的因素。如果指南支持这种做法，大多数医生至少在某种程度上同意将微小息肉留在原位。
胃肠病学家在切除微小息肉方面存在差异。研究结果对可变息肉检出率的解释和管理具有重要意义。
