Routine colonoscopy is generally safe for patients with end-stage renal disease (ESRD) on dialysis, though adverse events are more common than in healthy adults. Careful consideration is advised for older hemodialysis patients.
Area of Science:
- Nephrology
- Gastroenterology
- Clinical Medicine
Background:
- Limited data exists on the safety of routine colonoscopy in end-stage renal disease (ESRD) patients, including bowel preparation and sedation.
- Colonoscopy is frequently performed in ESRD patients, necessitating an understanding of associated risks.
Purpose of the Study:
- To investigate the safety of colonoscopy in patients with ESRD undergoing peritoneal dialysis (PD) or hemodialysis (HD).
- To compare the incidence of adverse events (AEs) in ESRD patients versus a healthy control group.
Main Methods:
- Retrospective review of 538 ESRD patients who underwent colonoscopy (2010-2020).
- Propensity score-matched comparison with healthy adults to analyze cardiovascular/pulmonary and procedure-related AEs.
- Comparison of AE rates between PD and HD groups.
Main Results:
- Overall AE rate in ESRD patients was 5.7%, significantly higher than healthy adults (0.6%).
- All AEs were cardiovascular/pulmonary; no perforations or bleeding occurred. Most AEs were mild.
- AE incidence was higher in hemodialysis (HD) than peritoneal dialysis (PD) patients (6.1% vs. 3.5%), but not statistically significant.
Conclusions:
- Colonoscopy-related AEs in ESRD patients on dialysis are more frequent than in healthy individuals but are typically not severe.
- Routine colonoscopy can be safely performed in ESRD patients, irrespective of dialysis modality.
- Increased caution is recommended for older ESRD patients undergoing hemodialysis.
