BACKGROUND: The role of operator fatigue on adenoma detection rate (ADR) is still controversial. AIMS: The purpose of this study was to determine if fatigue towards the end of the week affects the ADR. METHODS: A retrospective chart review of consecutive colonoscopies was done at a tertiary care teaching institution. Patients 45 years of age or older undergoing screening or surveillance colonoscopy from June 2007 to August 2010 were included in the study. RESULTS: A total of 3,085 patients were included in the study, with an overall 31 % ADR. ADR was between 31 and 32 % throughout the week, with no statistically significant variation (p = 0.8697). The total number of adenomas and advanced adenomas was also similar throughout the week (p = 0.8, p = 0.59, respectively). CONCLUSIONS: ADR is not influenced by the day of the week in which a colonoscopy is performed.
