Diclofenac sodium versus ceftazidime for preventing pancreatitis after endoscopic retrograde cholangiopancreatography: a prospective, randomized, controlled trial.

Background and Aims: We aimed to compare the efficacy of prophylactic, parenterally administered ceftazidime and rectally applied diclofenac sodium for the prophylaxis of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). Methods: We prospectively enrolled patients who underwent ERCP. In a doubleblinded randomized controlled trial, patients received a suppository containing diclofenac sodium rectally (100 mg) and placebo intravenously (group A) or ceftazidime intravenously (1 g) and placebo rectally (group B) immediately before the procedure. The serum and urine amylase levels were recorded and the patients were clinically evaluated after ERCP. Results: Of the 272 patients enrolled (group A: 129 ; group B: 143), 32 developed pancreatitis (group A: 11 [8.5%] ; group B: 21 [14.7%] ; P = 0.17 ; relative risk = 1.72 ; 95% confidence interval [CI] = 0.86-3.43). The severity of the pancreatitis or complications did not significantly differ between the groups. A serum amylase level of ≥ 560 U/L and urine amylase level of ≥ 1150 U/L indicated a positive likelihood ratio for post-ERCP pancreatitis of ≥ 10. Moreover, the threshold visual analog scale score of ≤ 5 for abdominal pain after ERCP had excellent diagnostic potential for predicting the presence or absence of post-ERCP pancreatitis. Conclusions: The PEP incidence did not differ between the ceftazidime and diclofenac sodium groups. In patients with nonsteroidal anti-inflammatory drug contraindications, antibiotics can be considered a safe alternative to diclofenac sodium for PEP prevention. Moreover, the visual analog scale for abdominal pain has excellent diagnostic value for predicting PEP. Clinical trials.gov number, NCT 01784445.
