pasireotide and Anastomotic-Leak

Morbidity after pancreatectomy is commonly due to leakage of exocrine secretions resulting in abscess or pancreatic fistula (PF). Previously, we authored a double-blind randomized controlled trial demonstrating that perioperative pasireotide administration lowers abscess or PF formation by >50%. Accordingly, we adopted pasireotide use as standard practice after pancreatectomy in October 2014 and hypothesized a similar PF/abscess rate reduction would be observed.. A prospectively maintained database was queried for all patients who underwent pancreatectomy between October 2014 and July 2017. Pasireotide was administered preoperatively and twice daily for 7 days postoperatively or until discharge. The primary end point was clinically relevant PF/abscess requiring procedural intervention, identical to the earlier trial outcomes. Logistic regression was used to compare outcomes with the placebo arm of the earlier randomized trial and to control known PF risk factors.. During the 34-month study period, 652 patients underwent pancreatectomy (211 distal pancreatectomy, 441 pancreaticoduodenectomy). Compared with the historical placebo group (n = 148), the observational group had an increased prevalence of higher American Society of Anesthesiologists scores (69% vs 54%; p < 0.001) and high-risk cases (small duct and soft gland, 47% vs 36%; p = 0.030). The primary end point occurred in 13.3% of patients receiving pasireotide vs 20.9% in the placebo arm of the earlier trial trial (odds ratio 0.58; 95% CI 0.37 to 0.92; p = 0.020). Biliary leakage was lower in those receiving pasireotide (0.6% vs 3.4%; p = 0.014), and other morbidity was unchanged. No subpopulation was identified more likely to benefit from pasireotide.. At our center, adoption of pasireotide has allowed us to achieve a clinically significant abscess or pancreatic leak rate of 13.3%, approximating the effect observed in the randomized trial of pasireotide during routine surgical practice.

Pasireotide decreases leak rates after pancreatic resection, though significant drug cost may be prohibitive. We conducted a cost-effectiveness analysis to determine whether prophylactic pasireotide possesses a reasonable cost profile.. A cost-effectiveness model compared pasireotide administration after pancreatic resection versus usual care, populated by probabilities of clinical outcomes from a randomized trial and hospital costs (2013 US$) from a university pancreatic disease center. Sensitivity analyses were performed to identify influential clinical components of the model.. With the cost of pasireotide included, per patient costs of pancreatectomy, including those for readmission, were lower in the intervention arm (41,769 versus 42,159$; net savings of 390$, or 1%). This was associated with a 56% reduction in pancreatic fistula/pancreatic leak/abscess (PF/PL/A; 21.9-9.2%). Pasireotide cost would need to increase by over 15.4% to make the intervention strategy more costly than usual care. Sensitivity analyses exploring variability of key model inputs demonstrated that the three strongest drivers of cost were (i) cost of pasireotide; (ii) probability of readmission; and (iii) probability of PF/PL/A.. Prophylactic pasireotide administration following pancreatectomy is cost savings, reducing expensive post-operative sequealae (major complications and readmissions). Pasireotide should be utilized as a cost-saving measure in pancreatic resection. J. Surg. Oncol. 2016;113:784-788. © 2016 Wiley Periodicals, Inc.
