The Preoperative Prognostic Nutritional Index Predicts the Development of Deep Venous Thrombosis After Pancreatic Surgery.

BACKGROUND/AIM: Pancreatic surgery is associated with a high risk of developing deep venous thrombosis (DVT) and malnutrition. We aimed to evaluate the factors predicting the development of DVT, focusing on nutrition assessment tools. PATIENTS AND METHODS: One hundred patients who underwent pancreatic surgery were postoperatively examined for DVT. We assessed the risk factors for the development of DVT after surgery. RESULTS: Postoperative DVT was detected in 11 patients (11%). Patients who developed DVT after surgery were significantly older (p=0.016) and had higher preoperative D-dimer levels (p=0.005) than those who did not. The preoperative prognostic nutritional index (PNI) was mostly associated with the development of DVT (p=0.079). Furthermore, PNI 20 mg/dl, D-dimer >/=1.9 mug/ml were independent predictors for the development of DVT after surgery. CONCLUSION: A poor nutrition status and dehydration should be preoperatively improved for patients who are identified, as having a high risk of developing DVT after pancreatic surgery.
