Scoring System to Predict Pancreatic Fistula After Pancreaticoduodenectomy: A UK Multicenter Study.
OBJECTIVE To validate a preoperative predictive score of postoperative pancreatic fistula (POPF) Other risk factors for POPF were sought in an attempt to improve the score. BACKGROUND POPF is the major contributor to morbidity after pancreaticoduodenectomy (PD) A preoperative score [using body mass index (BMI) and pancreatic duct width] to predict POPF was tested upon a multicenter patient cohort to assess its performance. METHODS Patients undergoing PD at 8 UK centers were identified. The association between the score and other pre intra and postoperative variables with POPF was assessed. RESULTS A total of 630 patients underwent PD with 141 occurrences of POPF (22.4% BMI, perirenal fat thickness, pancreatic duct width on computed tomography and at operation, bilirubin, pancreatojejunostomy technique, underlying pathology, T stage, N stage, R status, and gland firmness were all significantly associated with POPF. The score predicted POPF (P 0.001) with a higher predictive score associated with increasing severity of POPF (P 0.001) Stepwise multivariate analysis of pre intra and postoperative variables demonstrated that only the score was consistently associated with POPF. A table correlating the risk score to actual risk of POPF was created. CONCLUSIONS The predictive score performed well and could not be improved. This provides opportunities for individualizing patient consent and selection, and treatment and research applications.
