摘要

目的

探究结肠镜检查中，活检率和活检阳性率是否可作为评估内镜医师诊断水平的有效指标。

方法

选取陆军军医大学第一附属医院消化内镜中心、贵黔国际总医院消化内镜中心、中国人民解放军陆军第九五八医院消化内镜中心的15名内镜医师作为研究对象。根据年资分为高年资组（

=8）和低年资组（

=7），根据性别分为男医师组（

=9）和女医师组（

=6），根据工作时间分为上午时段（8：00~12：00）和下午时段（13：00~18：00）。收集其在2023年01月至2023年12月期间检查的所有患者数据，共纳入28 949名检查病例。采用单因素方差分析，探讨内镜医师年资、性别以及不同工作时段对活检率、活检阳性率之间的差异。同时，采用多因素Logistic回归分析影响活检阳性率的独立危险因素。

结果

高年资组活检率低于低年资组［（5.73±0.81）%

（6.89±0.97）%，

0.01］，但活检阳性率高于低年资组［（53.52±3.87）%

（33.70±7.85）%，

0.01］；所有医师组上午时段活检率高于下午时段结肠镜检查活检率［（6.76±1.11）%

（5.53±1.57）%，

0.05］；Logistic回归分析显示医师年资［（53.52±3.87）%

（33.70±7.85）%，

0.01，

=92.187，95%

：3.118~2725.366］、工作时间段［（48.35±10.50）%

（37.80±10.65）%，

0.05，

=20.885，95%

：1.266~344.602］是活检阳性率的影响因素。

结论

高年资内镜医师的活检率低而活检阳性率高，低年资活检率高但活检阳性率低，表明活检率、活检阳性率与内镜医师诊断水平相关。

Abstract

Objective‍　‍To explore whether the biopsy rate and the positive rate of biopsy during colonoscopy can serve as effective indicators for evaluating the diagnostic proficiency of endoscopists. Methods‍　‍Total fifteen endoscopists from the First Affiliated Hospital of Army Military Medical University

Guiqian International General Hospital and No. 958 Hospital of PLA Army were enrolled and served as the study subjects. According to their years of experience

gender and working hours

they were divided into a senior group (n=8) and a junior group (n=7)

a male group (n=9) and a female group (n=6)

and a morning period (08:00-12:00) and an afternoon period (13:00-18:00). The data of all patients examined by the aforementioned endos

copists between January 2023 and December 2023 were collected

including the basic demographics

colonoscopic results

biopsy outcomes and pathological diagnoses of the patients. ANOVA was used to analyze the differences in the biopsy rate and positive rate of biopsy existed among the endoscopists of different years of experience

gender and working at different periods (morning and afternoon). Additionally

multivariate logistic regression analysis was employed to identify the independent risk factors associated with positive rates of biopsy. Results‍　‍The senior group had significantly lower biopsy rate [(5.73±0.81)%

(6.89±0.97)%

]

but obviously higher positive rate of biopsy [(53.52±3.87)%

(33.70±7.85)%

]

than the junior group (both

0.01). The biopsy rate was notably higher during the morning working time period than the afternoon working time period in all the endoscopits [(6.76±1.11)%

(5.53±1.57)%

0.05

]

. Logistic regression analysis showed that the years of experience [(53.52±3.87)%

(33.70±7.85)%

=92.187

95%

: 3.118~2 725.366

0.01) and working time [(48.35±10.50)%

(37.80±10.65)%

=20.885

95%

: 1.266~344.602

0.05) were influencing factors for positive rate of biopsy. Conclusion‍　‍The biopsy rate is low and positive rate of biopsy is high among the senior experienced endoscopists

while

opposite results are seen in the junior experienced clinicians

indicating correlation of biopsy rate and positive rate of biopsy with diagnostic proficiency of endoscopists.
