Background: The present study aims to assess whether the use of anesthesia services during colonoscopy is associated with an increased risk of rare complications.
Methods: A search of Medline, PubMed and Cochrane databases identified studies that compared complication rates of colonoscopies performed with the use of anesthesia services versus endoscopist-administered sedation. The four outcome variables analyzed were aspiration pneumonia, bowel perforation, splenic injury, and overall complication rate. Random effects meta-analyses were performed using an odds ratios (OR). The ROBINS1 tool was used to assess the studies for risk of bias.
Results: Eight retrospective cohort studies were considered suitable for meta-analysis consisting of 7,752,580 colonoscopies. Use of anesthesia services during colonoscopy was associated with an increased risk of aspiration pneumonia (OR 1.79 (1.34, 2.38), P < 0.0001). There was no association found between the use of anesthesia services during colonoscopy and splenic injury rate (OR 0.90 (0.61, 1.31, P = 0.58), bowel perforation (OR 1.33 (0.95, 1.88), P = 0.10), or overall complication rate (OR 1.33 (0.99, 1.79), P = 0.06).
Conclusions: An increased risk of aspiration pneumonia is associated with the use of anesthesia services during colonoscopy. This risk should be considered when anesthesia services are used.
