Abstract Background Despite abundant, high-level scientific evidence, there is no consensus regarding the prevention, mitigation, and management of clinically relevant pancreatic fistula after pancreatoduodenectomy. The aim of the present investigation is three-fold: (1) to analyze the multiple decision-making points for pancreatico-enteric anastomotic creation and fistula mitigation and management after pancreatoduodenectomy, (2) to reveal the practice of contemporary experts, and (3) to indicate avenues for future research to reduce the burden of clinically relevant pancreatic fistula. Methods A 109-item questionnaire was sent to a panel of international pancreatic surgery experts, recognized for their clinical and scientific authority. Their practice habits and thought processes regarding clinically relevant pancreatic fistula risk assessment, anastomotic construction, application of technical adjuncts, and mitigation strategies, as well as postoperative management, was explored. Sixteen clinical vignettes were presented to reveal their certain approaches to unique situations—both common and uncommon. Results Sixty experts, with a cumulative 48,860 pancreatoduodenectomies, completed the questionnaire. Their median pancreatectomy/pancreatoduodenectomy case volume was 1,200 and 705 procedures, respectively, with a median career duration of 22 years and 200 indexed publications. Although pancreatico-jejunostomy reconstruction with transperitoneal drainage is the standard operative approach for most authorities, uncertainty emerges regarding the employment of objective risk stratification and adaptation of practice to risk. Concrete suggestions are offered to inform decision-making in intimidating circumstances. Early drain removal is frequently embraced, while a step-up approach is unanimously invoked to treat severe clinically relevant pancreatic fistula. Conclusion A comprehensive conceptual framework of 4 sequential phases of decision-making is proposed—risk assessment, anastomotic technique, mitigation strategy employment, and postoperative management. Basic science studies and outcome analyses are proposed for improvement.

Abstract Background Postoperative pancreatic fistula continues to occur frequently after pancreatoduodenectomy. Methods We have described a modification of the Blumgart pancreaticojejunostomy. The modification of the Blumgart pancreaticojejunostomy was compared to the Cattel-Warren pancreaticojejunostomy in cohorts of patients matched by propensity scores based on factors predictive of clinically relevant postoperative pancreatic fistula, which was the primary endpoint of this study. Based on a ...

Abstract Background Pancreatoduodenectomies at high risk for clinically relevant pancreatic fistula are uncommon, yet intimidating, situations. In such scenarios, the impact of individual surgeon experience on outcomes is poorly understood. Methods The fistula risk score was applied to identify high-risk patients (fistula risk score 7–10) from 7,706 pancreatoduodenectomies performed at 18 international institutions (2003–2020). For each case, surgeon pancreatoduodenectomy career volume and years...

Abstract Background Serum amylase activity greater than the institutional upper limit of normal (hyperamylasemia) on postoperative day 0-2 has been suggested as a criterion to define postoperative acute pancreatitis after pancreatoduodenectomy, but robust evidence supporting this definition is lacking. Background To assess the clinical impact of hyperamylasemia after pancreatoduodenectomy and to define postoperative acute pancreatitis. Methods Data of 1,235 consecutive patients who had undergone...

OBJECTIVE: The aim of the study was to validate and optimize the alternative Fistula Risk Score (a-FRS) for patients undergoing minimally invasive pancreatoduodenectomy (MIPD) in a large pan-European cohort. BACKGROUND: MIPD may be associated with an increased risk of postoperative pancreatic fistula (POPF). The a-FRS could allow for risk-adjusted comparisons in research and improve preventive strategies for high-risk patients. The a-FRS, however, has not yet been validated specifically for lapa...

Abstract Background Postoperative hyperamylasemia is a frequent finding after pancreatoduodenectomy, but its incidence and clinical implications have not yet been analyzed systematically. The aim of this review is to reappraise the concept of postoperative hyperamylasemia with postoperative acute pancreatitis, including its definition, interpretation, and correlation. Methods Online databases were used to search all available relevant literature published through June 2019. The following search ...

OBJECTIVE To investigate the role of intraoperative EBL on development of CR-POPF after pancreatoduodenectomy (PD). BACKGROUND Minimizing EBL has been shown to decrease transfusions and provide better perioperative outcomes in PD. EBL is also felt to be influential on CR-POPF development. METHODS This study consists of 5534 PDs from a 17-institution collaborative (2003-2018). EBL was progressively categorized (≤150 mL; 151-400 mL; 401-1,000 mL; >1,000 mL). Impact of additive EBL was assessed usi...

Importance Postoperative complications remain common after surgery, but little is known about the extent of variation in operative technical skill and whether variation is associated with patient outcomes. Objectives To examine the (1) variation in technical skill scores of practicing surgeons, (2) association between technical skills and patient outcomes, and (3) amount of variation in patient outcomes explained by a surgeon’s technical skill. Design, Setting, and Participants In this quality i...

Abstract Background The role of wrapping in the setting of pancreaticoduodenectomy (PD) is controversial. This study aimed to assess whether the use of omental or falciform ligament wrapping of pancreatic anastomosis and/or vessels could reduce the rate of POPF and postpancreatectomy hemorrhage (PPH) after PD. Methods Studies comparing PD with (PD-W) and without wrapping (PD-nW) were included. Primary outcomes were POPF and extraluminal PPH. Dichotomous variables were analyzed for risk ratios (R...
