Does Postoperative Colonoscopy Increase the Risk for Hip and Knee Periprosthetic Joint Infection? A Systematic Review...

Area of Science:

• Orthopedic Surgery
• Infectious Disease
• Gastroenterology

Background:

• Periprosthetic joint infections (PJI) are a significant complication following total joint arthroplasty (TJA).
• Hematogenous spread from remote sites is a common cause of PJI, necessitating antibiotic prophylaxis for certain procedures.
• Conflicting evidence exists regarding the risk of PJI after colonoscopy in TJA patients.

Purpose of the Study:

• To systematically review and meta-analyze the risk of PJI after colonoscopy in patients who have undergone TJA.
• To provide evidence-based guidance on the safety of colonoscopies in TJA patients.

Main Methods:

• Systematic search of Embase, MEDLINE, CINAHL, and CENTRAL databases.
• Inclusion of five cohort studies with a total of 505,079 patients.
• Meta-analysis using random-effects models and the generic inverse variance method.

Main Results:

• No significant increase in PJI risk was observed at three months, six months, nine months, or one year post-colonoscopy.
• Pooled data showed no statistically significant association between colonoscopy and PJI.
• Independent risk factors for PJI include diabetes, rheumatoid arthritis, chronic kidney disease, alcohol abuse, tobacco use, pulmonary disease, male sex, and post-traumatic arthritis.

Conclusions:

• Postoperative colonoscopies do not significantly increase PJI risk in TJA patients.
• While the procedure appears safe overall, identifying and modifying individual risk factors is crucial for mitigating PJI.
• Proactive management of risk factors can improve outcomes for TJA patients undergoing colonoscopy.
