Background:
Pasireotide is a newer generation somatostatin analogue that led to a significant reduction in pancreatic fistula after pancreatectomy in a single-center randomized controlled trial. We sought to determine if pasireotide reduces the incidence of pancreatic fistula and other complications after pancreaticoduodenectomy at our high volume center.
Study Design:
All patients undergoing pancreaticoduodenectomy between April 2011 and January 2017 were prospectively followed, and their complications were graded using the Modified Accordion Grading System (MAGS) in our institutional complications database. For 18 months, 5 pancreatic surgeons used pasireotide routinely in patients undergoing pancreaticoduodenectomy. Patients receiving pasireotide were then propensity score-matched to patients who did not receive pasireotide, and their outcomes were compared.
Results:
There were 459 patients who underwent pancreaticoduodenectomy, and 127 patients (28%) received pasireotide. Patients who received pasireotide were significantly more likely to have dilated pancreatic ducts and have a drain left at the time of surgery. Patients who received pasireotide had no difference in pancreatic fistula, overall complications, 90-day readmission, or 90-day mortality. However, patients who received pasireotide had a significantly reduced rate of postoperative bleeding/anemia (8.7% vs 16.9%, p = 0.03). Among 112 propensity score-matched pairs, patients who received pasireotide did not have significantly different rates of pancreatic fistula, and the rates of severe (MAGS grades 3 to 6) pancreatic fistula were identical between the 2 groups (7.1% vs 7.1%, p = 1.00). Matched patients who received pasireotide had significantly decreased postoperative bleeding/anemia (9.8% vs 19.6%, p = 0.04).
Conclusions:
Pasireotide did not reduce the incidence or severity of pancreatic fistulas after pancreaticoduodenectomy, but was associated with a decrease in postoperative bleeding/anemia. A multicenter randomized trial is needed to accurately define the role of pasireotide in the postoperative management of pancreaticoduodenectomy patients.
