Abstract
Background Clinically relevant postoperative pancreatic fistulas (CR-POPF) are serious inherent risks of pancreatic resection. Preoperative CR-POPF risk assessment is currently inadequate and rarely disqualifies patients who need resection. The best evaluation of risk occurs intraoperatively, and should guide fistula prevention and response measures thereafter. We sought to develop a risk prediction tool for CR-POPF that features intraoperative assessment and reveals associated clinical and economic significance. Study Design Based on International Study Group of Pancreatic Fistula classification, recognized risk factors for CR-POPF (small duct, soft pancreas, high-risk pathology, excessive blood loss) were evaluated during pancreaticoduodenectomy. An optimal risk score range model, selected from 3 different constructs, was first derived (n = 233) and then validated prospectively (n = 212). Clinical and economic outcomes were evaluated across 4 ranges of scores (negligible risk, 0 points; low risk, 1 to 2; intermediate risk, 3 to 6; high risk, 7 to 10). Results Clinically relevant postoperative pancreatic fistulas occurred in 13% of patients. The incidence was greatest with excessive blood loss. Duct size Conclusions A simple 10-point Fistula Risk Score derived during pancreaticoduodenectomy accurately predicts subsequent CR-POPF. It can be readily learned and broadly deployed. This prediction tool can help surgeons anticipate, identify, and manage this ominous complication from the outset.

Introduction Although mortality rates from pancreatectomy have decreased worldwide, death remains an infrequent but profound event at an individual practice level. Root-cause analysis is a retrospective method commonly employed to understand adverse events. We evaluate whether emerging mortality risk assessment tools sufficiently predict and account for actual clinical events that are often identified by root-cause analysis.

Background Hospital readmission is under increased scrutiny as a quality metric for surgical performance, yet its relevance after elective, high-acuity operations is poorly understood. We sought to define the clinical nature and economic impact of readmission after major pancreatic resection. Study Design From 2001 to 2009, 578 pancreatic resections followed standardized perioperative care. Clinical and economic outcomes were evaluated and predictors of readmission were identified by regression ...

Abstract Postoperative pancreatic fistula is an important complication after pancreatic resection. The frequency of its incidence varies between 3% after pancreatic head resections and up to 30% following distal pancreatectomy. In recent years, the international definition of pancreatic fistula has been standardised according to the approach of the International Study Group on Pancreatic Fistula (ISGPF). Consequently, results from different studies have become comparable and the historically rep...

Objective: Pancreatic fistula (PF) is a leading cause of morbidity and mortality after pancreaticoduodenectomy (PD). The aim of this multicenter prospective randomized trial was to compare the results of PD with an external drainage stent versus no stent. Methods: Between 2006 and 2009, 158 patients who underwent PD were randomized intraoperatively to either receive an external stent inserted across the anastomosis to drain the pancreatic duct (n = 77) or no stent (n = 81). The criteria of inclu...

Abstract Background Postoperative pancreatic fistula (POPF) is regarded as the most serious complication of pancreatic surgery. The preoperative risk stratification of patients by simple means is of interest in perioperative clinical management. Methods Based on prospective data, we performed a risk factor analysis for POPF after pancreatoduodenectomy in 62 patients operated between 2006 and 2008 with special focus on clinical parameters that might serve to predict POPF. A predictive score was d...

Despite significant improvements in the safety and efficacy of pancreatic surgery, post-operative pancreatic fistulae remain an unsolved dilemma. These occur when the transected pancreatic gland, pancreatic-enteric anastomosis, or both, leak rendering the patient at significant risk. They are especially important today since indications for resection (IPMN, carcinoma) continue to increase. This review considers definitions and classifications of pancreatic fistulae, risk factors, preventative ap...

Clinically relevant postoperative pancreatic fistula (CR-POPF) is a life-threatening complication following pancreaticoduodenectomy (PD). Individualized preoperative risk assessment could improve clinical management and prevent or mitigate adverse outcomes. The aim of this study is to develop a machine learning risk model to predict occurrence of CR-POPF after PD from preoperative computed tomography (CT) scans. A total of 100 preoperative high-quality CT scans of consecutive patients who underw...

No accepted benchmarks for open pancreaticoduodenectomy (PD) exist. The study assessed the time to functional recovery after open PD and how this could be affected by the magnitude of midline incision (MI). Prospective snapshot study during 1 year. Time to functional recovery (TtFR) was assessed for the entire cohort. Further analyses were conducted after excluding patients developing a Clavien-Dindo ≥ 2 morbidity and after stratifying for the relative length of MI. The overall median TtFR was 7...

PURPOSE In this study, it was aimed to determine the predictors of clinically relevant postoperative pancreatic fistula (CR-POPF) following pancreaticoduodenectomy (PD) and clinical significance of mean platelet volume (MPV)/total platelet count ratio (MPR) as a new predictor for CR-POPF. METHODS A total of 105 patients who underwent PD consecutively due to periampullary located diseases were included in the study. Patients were divided into two groups as CR-POPF and no postoperative pancreatic ...

Abstract null null Background null Although several prediction models for the occurrence of clinically relevant postoperative pancreatic fistula after laparoscopic pancreatoduodenectomy exist, most were established using Western cohorts. The utility of these models using a Chinese cohort has not been validated widely.
