Objective: To observe polyp/adenoma detection rate of sigmoidoscopy among doctors with different skill level.
Method: 5 doctors examined healthy checkups respectively. Upon detection, diagnosis adenoma/non-adenoma according to Kudo classification. Recommend total colonoscopy (TC) resection for adenomas.
Results: 1666 healthy checkups examined. 201 resection recommendations were made, and 120 actually received TC adenoma resection. All doctors finish sigmoidoscopy successfully, with different intubation depth. Intubation depth is highly related with prior finished TC number of the doctor. R value is 0.7593 for reaching descending, 0.9416 for transcending, 0.9786 for ascending colon. Total polyp detection rate 32.05%, adenoma detection rate (ADR) 12.06%. ADR vary significantly among doctors, from 9.39% to 17.36%. ADR also highly related with prior finished TC number, R = 0.8234. Adenoma diagnosis was verified with histology, from 72.73% to 91.67%. There is no difference among doctors, p = 0.9716. Total adenoma missing rate of sigmoidoscopy is 17.5%. There is no difference among doctors, p = 0.3898.
Conclusions: The ADR of sigmoidoscopy is fare. Skill level has important influence to ADR of sigmoidoscopy, but not diagnosis accuracy.
