BACKGROUND: Pancreatic fistula (PF) remains the most challenging complication in pancreatic surgery, yet few published studies have focused on the risk factors for postoperative PF in patients undergoing surgery for insulinomas. METHODS: From January 1990 to February 2010, a total of 292 patients with insulinomas underwent surgery at Peking Union Medical College Hospital. Demographic data, intraoperative procedures, and postoperative data were collected. Particular attention was paid to variables associated with PF as defined by the International Study Group of Pancreatic Fistula (ISGPF). Univariate and multivariate analyses were used to identify possible risk factors for PF. RESULTS: PF was found in 132 (45.2%) patients, of whom 90 were classified into ISGPF grade A, 33 grade B, and 9 grade C. Multivariate analysis showed that male patients (OR=2.56; P=0.007) and operative time >180 minutes (OR=3.756; P180 minutes were independent risk factors for clinical PF, while pancreatic resection with a stapler was a protective factor. Whether body mass index (BMI) and other variables during operation are risk factors of PF needs further study. © 2012, Hepatobiliary Pancreat Dis Int.
