OBJECTIVES: Previous reports suggested that the urine trypsinogen 2 (U-TRP2) test might be a valuable method for the diagnosis of postoperative pancreatitis after pancreatic surgery. We hypothesize that the elevation of U-TRP2 level after pancreaticoduodenectomy (PD) could be associated with the occurrence of postoperative pancreatic fistula (POPF).
METHODS: A total of 130 consecutive patients undergoing PD with duct-to-mucosa pancreaticogastrostomy were included. Urine samples for evaluation of U-TRP2 levels were collected prospectively. Risk factors for POPF were evaluated using univariate and multivariate analyses.
RESULTS: Of 130 patients, 19 developed POPF; grade A in 14 (11%), grade B in 3 (2%), and grade C in 1 (1%). Univariate analysis demonstrated that a nonobstructed main pancreatic duct, a pancreatic duct less than 3 mm, soft texture of the pancreatic gland, a PD with antrectomy, PD with hepatic resection, hyperamylasemia, and elevation of U-TRP2 levels (>50 μg/L) were significantly associated with POPF (P < 0.05). By multivariate analysis, elevation of U-TRP2 levels (odds ratio = 4.544, P = 0.029) was the only independent risk factor that correlated with POPF.
CONCLUSIONS: Elevation of U-TRP2 level is an independent risk factor for POPF after PD. Elevated U-TRP2 level might be the consequence of the postoperative pancreatitis, and postoperative pancreatitis may play an important role in the pathogenic mechanism of POPF after PD.
