BACKGROUND: Effects of octreotide on post-endoscopic retrograde cholangiopancreatography pancreatitis have been studied in many clinical trials. These trials have yielded inconclusive results. Results of more recent studies using larger doses, however, seem to be more optimistic.
AIM: To examine effects of octreotide at different doses on PEP.
METHODS: A comprehensive search of relevant databases, including Medline, Embase, the Cochrane Controlled Trials Register, the Cochrane Library and Science Citation Index yielded 18 randomized controlled trials (RCTs). Trials were divided into two groups according to the total dosage of octreotide:<0.5 mg (OCT1),>or =0.5 mg (OCT2). The rate of PEP was analysed using a fixed effect model.
RESULTS: At doses of>or =0.5 mg, octreotide reduced the rate of PEP. In the OCT2 group, analysis revealed a statistically significant difference on PEP between the octreotide group and the controls (3.4% vs. 7.5%, pooled OR = 0.45; 95% CI:0.28-0.73; P = 0.001, NNT = 25). In the OCT1 group, the rate of PEP was similar between patients receiving octreotide and the controls (7.2% vs. 6.0%, pooled OR = 1.23; 95% CI: 0.80-1.91; P = 0.35).
CONCLUSION: Octreotide is effective in preventing PEP, but only at sufficient doses (>or =0.5 mg).
