Abstract

Background

Routine rectal administration of 100 mg of diclofenac or indomethacin was demonstrated to be an effective prevention method to prevent post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. The systematic review and meta-analysis aimed to estimate the incidence and severity of post-ERCP pancreatitis (PEP) and explore the discrepancies of PEP incidences among different subgroups.

Methods

The PubMed, Web of Science, and Ovid EMBASE databases were searched for studies published until December 2020. Only randomized controlled trials (RCTs) reported rectal administration of 100 mg or higher doses of diclofenac or indomethacin, with PEP as the primary outcomes were eligible for inclusion. The overall and severity of PEP were estimated. Subgroup analysis was performed based on geographic regions, risk level, study beginning time, type of NSAIDs, administration time, and sample size.

Results

There were 26 randomized controlled trials (RCTs) with 7954 patients in 31 NSAIDs arms. The pooled incidences were 7.2% for overall PEP (95% confidence interval (CI) 5.9–8.5%), 5.0% for mild PEP (95% CI, 4.0–6.0%), and 1.5% for moderate and severe PEP (0.8–2.3%). PEP rate were higher in patients receiving rectal indomethacin than that of patients receiving rectal diclofenac (7.8% (95% CI, 6.4–9.3%) vs 3.8% (95% CI, 2.2–5.3%), p = 0.009). The PEP rates of high-risk patients and average-risk patients were 8.9% (95% CI, 5.6–12.2%) and 6.4% (95% CI, 5.1–7.6%), respectively (p = 0.160).

Conclusions

The incidence of PEP was higher in patients receiving 100 mg rectal indomethacin than patients receiving 100 mg diclofenac. The effect of 100 mg diclofenac versus indomethacin on preventing PEP requires further study.
