Somatostatin Analogs for Preventing Postoperative Pancreatic Fistula: Past Evidence Reveals New Opportunities

Abstract

Postoperative pancreatic fistula (POPF) is the defining complication following pancreatectomy. The incidence of POPF after pancreatic resection remains high even at experienced centers, with associated patient morbidity, increased healthcare costs, and poorer oncologic outcomes. There is evidence that POPF is more frequent after distal pancreatectomy. On the basis of the premise that reduction in pancreatic exocrine secretion reduces the risk of fistula formation, somatostatin analogs (SSA) to prevent POPF and its sequelae have been studied for more than 30 years. However, evidence regarding their efficacy remains mixed. Early multicenter randomized control trials demonstrated a benefit of octreotide in reducing POPF, although subsequent single-center studies failed to confirm these results. Despite additional studies demonstrating a significant reduction in POPF with the use of newer SSAs including pasireotide and lanreotide, surgical practices in the use of somatostatin analogs in preventing POPF are highly variable. Herein, we review three decades of available data on SSA for POPF prophylaxis and highlight the need for pragmatic, focused, and data-driven design for future trials with modern agents.
