Abstract

Purpose

Investigation of the role of sedation during colonoscopy is meaningful as the advantages of colonoscopy performing with sedation are still controversial.

Methods

Medical records of patients who underwent colonoscopy in our institution were retrospectively analyzed. The sedation rate, adenoma detection rate (ADR), polyp detection rate (PDR), cecal intubation rate (CIR), iatrogenic colonic perforation rate (ICP) were calculated.

Results

A total of 48,838 colonoscopies (24,498 in males) dated from July 2007 to February 2017 were analyzed. The median age was 50 years (range 16–85 years). An overall sedation rate was 80.38%. The PDR was 26.77%, and was not statistically different between colonoscopy with or without sedation (26.67% vs 27.22, p = 0.474). ADR was 12.9% regardless of applying sedation or not (13.0% vs 12.44%, p = 0.337). The CIR was 87.42% in all examinations with an adjusted CIR of 90.34%, and was higher when performed with sedation than without sedation (88.92% vs 80.64%, p < 0.0001). Five cases (0.01%) of ICP were reported, all of which occurred in patients under sedation.

Conclusions

The use of sedation is associated with increased CIR, but ADR and PDR remain unchanged with or without sedation. However, perforation rate, albeit very low, is significantly higher in sedated patients.
