Risk factors affecting pancreatic fistulas after pancreaticoduodenectomy.

AIM: To analyze the risk factors of pancreatic leakage after pancreaticoduodenectomy.

METHODS

We retrospectively reviewed 172 consecutive patients who had undergone pancreatico-duodenectomy at Inha University Hospital between April 1996 and March 2006. We analyzed the pancreatic fistula rate according to the clinical characteristics, the pathologic and laboratory findings, and the anastomotic methods.

RESULTS

The incidence of developing pancreatic fistulas in patients older than 60 years of age was 21.7% (25/115), while the incidence was 8.8% (5/57) for younger patients; the difference was significant (P=0.03). Patients with a dilated pancreatic duct had a lower rate of post-operative pancreatic fistulas than patients with a non-dilated duct (P=0.001). Other factors, including clinical features, anastomotic methods, and pathologic diagnosis, did not show any statistical difference.

CONCLUSION

Our study demonstrated that pancreatic fistulas are related to age and a dilated pancreatic duct. The surgeon must take these risk factors into consideration when performing a pancreaticoduodenectomy.
