Pasireotide does not prevent postoperative pancreatic fistula: a prospective study.

BACKGROUND
Pancreatic fistula is a major cause of morbidity after pancreas surgery. In 2014, a single-center, randomized-controlled trial found pasireotide decreased pancreatic fistula rates. However, this finding has not been validated, nor has pasireotide been widely adopted.
METHODS
A single-arm study in 111 consecutive patients undergoing pancreatic resection April 2015-October 2016 was conducted. Beginning immediately before surgery, patients received 900 μg subcutaneous pasireotide twice daily for up to seven days. Fistula rates were compared to 168 historical controls from July 2013 to March 2015. The primary outcome was Grade B/C fistula, as defined by the International Study Group on Pancreatic Fistula (ISGPF).
RESULTS
There were no significant differences between the pasireotide group and historical controls in demographics, comorbidities, operation type, malignancy, gland texture, or pancreatic duct size. Pasireotide did not reduce fistula rate (15.5% control versus 17.1% pasireotide, p = 0.72). In subgroup analyses of pancreaticoduodenectomy or distal pancreatectomy, or patients with soft gland texture and/or small duct size, there was no decrease in fistulas. Thirty-nine patients (38%) experienced dose-limiting nausea.
CONCLUSIONS
In an appropriately-powered, single-institution prospective study, pasireotide was not validated as a preventive measure for pancreatic fistula.
