BackgroundA randomized controlled trial (RCT) of routine administration of pasireotide demonstrated decreased incidence of clinically significant postoperative pancreatic fistula (POPF). Recent studies have not replicated these results. A meta-analysis was performed to evaluate its efficacy in this setting.MethodsProspective trials utilizing pasireotide prophylactically after pancreatectomy were reviewed. The primary outcome was clinically significant POPF. Secondary outcomes included length of stay (LOS), readmission rates, and mortality. Study heterogeneity was assessed.ResultsFive studies totaling 1571 patients were identified. There was no difference in age, sex, or cancer rates. Pasireotide patients had smaller pancreatic ducts (P ≤.001) and softer glands (P = .04). For all pancreatectomies, there was no difference in POPF rates (OR 0.84; 95% CI 0.60-1.16, P = .29). Patients undergoing distal pancreatectomy (OR 0.70; 95% CI 0.30-1.63, P = .41) had similar rates of POPF versus pancreaticoduodenectomy (PD) patients that experienced a lower incidence of POPF (OR 0.60; 95% CI 0.42-0.86, P = .006). Mortality rates and LOS were similar. Readmission rates were decreased with pasireotide (OR 0.61; 95% CI 0.44-0.85).ConclusionsRoutine administration of pasireotide did not decrease POPF rates for all pancreatectomies, but was associated with lower rates for PD and decreased readmission rates. Further prospective, randomized studies are warranted.
