[Analysis of pancreatic leaking-related risk factors after pancreaticoduodenectomy].

Objective: To analysis the risk factors of pancreatic fistula after pancreaticoduodenectomy (PD).

Methods: A retrospective clinical study had been done in 97 patients who underwent PD between June 2001 and June 2006. The two groups were first compared by the univariate analysis;logistic regression was then used to determine the effect of multiple factors on pancreatic fistula. A P-value of less than 0.05 was considered to be statistically significant.

Results: Of the 97 patients, 13 patients were identified as having pancreatic fistula. Factors significantly increasing the risk of pancreatic fistula by univariate analysis included preoperative serum total bilirubin (P = 0.038), operative time (P = 0.003) and whether or not Braun anastomosis (P = 0.034), and prophylactic use of somatostatin (P = 0.003) after operation. A multivariate logistic regression analysis revealed the factors most highly associated with pancreatic fistula to be preoperative serum total bilirubin (OR = 11.687, P = 0.021) and postoperative prophylactic use of somatostatin (OR = 0.056, P = 0.020).

Conclusions: Preoperative serum total bilirubin more than 170 mmol/L was a risk factor of pancreatic fistula after PD, and postoperative prophylactic use of somatostatin was a protect factor of pancreatic fistula after PD.
