CONTEXTSeveral surgical complications are related to obesity.OBJECTIVEThis study evaluated the impact of obesity on pancreatic fistula after pancreaticoduodenectomy.DESIGNWe retrospectively reviewed the medical records of 159 patients who underwent pancreaticoduodenectomy between October 2002 and December 2008.SETTINGThe patients were divided according to the body mass index as obese (body mass index equal to, or greater than, 25 kg/m(2)), or normal (body mass index less than 25 kg/m(2)).METHODSUnivariate and multivariate analyses were applied. Two-tailed P values less than 0.05 were considered as significant.RESULTSForty-six patients (28.9%) were obese and 113 patients (71.1%) were normal-weight. Obese group had a significantly higher incidence of pancreatic fistula and a greater amount of intraoperative blood loss. Other surgical complications were not significantly different between the two groups. Multivariate analysis found obesity, small pancreatic duct size (less than, or equal to, 3 mm), intraoperative blood loss, and combined resection as significant factors affecting pancreatic fistula.CONCLUSIONSObese patients have an increased risk for pancreatic fistula after pancreaticoduodenectomy.
