Abstract
Postoperative pancreatic fistula (POPF) is a major cause of morbidity and mortality after pancreatoduodenectomy (PD), and previous research has focused on patient-related risk factors and comparisons between anastomotic techniques. However, it is recognized that surgeon experience is an important factor in POPF outcomes, and that there is a significant learning curve for the pancreatic anastomosis. The aim of this study was to review the current literature on training models for the pancreatic anastomosis, and to explore areas for future research. It is concluded that research is needed to understand the mechanical properties of the human pancreas in an effort to develop a synthetic model that closely mimics its mechanical properties. Virtual reality (VR) is an attractive alternative to synthetic models for surgical training, and further work is needed to develop a VR pancreatic anastomosis training module that provides both high fidelity and haptic feedback.

Abstract
BACKGROUND Peripancreatic bacterial contamination (PBC) is a critical factor contributing to the development of clinically relevant postoperative pancreatic fistula (CR-POPF) following pancreaticoduodenectomy (PD). Controlling pathogenic bacteria is essential in preventing CR-POPF; however, the precise relationship between specific bacteria and CR-POPF remains unclear. This study aimed to investigate the relationship between PBC and CR-POPF after PD, with a focus on identifying potentially causative bacteria. METHODS This prospective observational study enrolled 370 patients who underwent PD. Microbial cultures were routinely collected from peripancreatic drain fluid on postoperative days (PODs) 1, 3, and 6. Predictive factors for CR-POPF and the bacteria involved in PBC were investigated. RESULTS CR-POPF occurred in 86 (23.2%) patients. In multivariate analysis, PBC on POD1 (Odds ratio [OR] = 3.59; P = 0.005) was one of the main independent predictive factors for CR-POPF, while prophylactic use of antibiotics other than piperacillin/tazobactam independently influenced PBC on POD1 (OR = 2.95; P = 0.010). Notably, Enterococcus spp., particularly Enterococcus faecalis, were significantly isolated from PBC in patients with CR-POPF compared to those without CR-POPF on PODs 1 and 3 (P < 0.001), and they displayed high resistance to all cephalosporins. CONCLUSIONS Early PBC plays a pivotal role in the development of CR-POPF following PD. Prophylactic antibiotic administration, specifically targeting Enterococcus faecalis, may effectively mitigate early PBC and subsequently reduce the risk of CR-POPF. This research sheds light on the importance of bacterial control strategies in preventing CR-POPF after PD.

Abstract
How to reduce grade C postoperative pancreatic fistula (POPF) incidence after pancreaticoduodenectomy (PD) is the pursuit of pancreatic surgeons. This study introduced an innovative pancreaticojejunostomy (PJ) technique with a complete set of perioperative management. All 144 patients in this single-center retrospective cohort study underwent the same PJ technique and perioperative management. The primary endpoint was grade C POPF incidence. The secondary endpoints were grade B POPF rate, drain fluid amylase level, complications, hospital stay duration, and mortality. Risk factors for clinically-relevant POPF (CR-POPF) were assessed by logistic regression analysis. No patient (0.0%) experienced grade C POPF, while 44 (30.6%) developed grade B. No in-hospital death was recorded. Multivariate analysis found relatively high body mass index, laparoscopic surgery, and soft or moderate pancreatic texture independent risk factors for CR-POPF. Our novel PJ anastomosis with modified perioperative management helped avoid grade C POPF. However, grade B POPF incidence was relatively high to some extent because of the enhanced management itself.

Abstract
BACKGROUND Recent studies support early drain removal after pancreaticoduodenectomy in patients with a drain fluid amylase on postoperative day 1 (DFA1) level of ≤5,000. The use of DFA1 to guide drain management is increasingly common among pancreatic surgeons; however, the benefit of checking additional drain fluid amylases beyond DFA1 is less known. We sought to determine whether a change in drain fluid amylase (ΔDFA) is a more reliable predictor of clinically relevant postoperative fistula than DFA1 alone. METHODS Using the American College of Surgeons National Surgical Quality Improvement Plan, pancreaticoduodenectomy patients with intraoperative drain placement, known DFA1, highest recorded drain fluid amylase value on postoperative day 2 to 5 (DFA2nd), day of drain removal, and clinically relevant postoperative fistula status were reviewed. Logistic models compared the predictive performance of DFA1 alone versus DFA1 + ΔDFA. RESULTS A total of 2,417 patients with an overall clinically relevant postoperative fistula rate of 12.6% were analyzed. On multivariable regression, clinical predictors for clinically relevant postoperative fistula included body mass index, steroid use, operative time, and gland texture. These variables were used to develop model 1 (DFA1 alone) and model 2 (DFA1 + ΔDFA). Model 2 outperformed model 1 in predicting the risk of clinically relevant postoperative fistula. According to model 2 predictions, the risk of clinically relevant postoperative fistula increased with any rise in drain fluid amylase, regardless of whether the DFA1 was above or below 5,000 U/L. The risk of clinically relevant postoperative fistula significantly decreased with any drop in drain fluid amylase, with an odds reduction of approximately 50% corresponding with a 70% decrease in drain fluid amylase (P < .001). A risk calculator was developed using DFA1 and a secondary DFA value in conjunction with other clinical predictors for clinically relevant postoperative fistula. CONCLUSION Clinically relevant postoperative fistula after pancreaticoduodenectomy is more accurately predicted by DFA1 and ΔDFA versus DFA1 in isolation. We developed a novel risk calculator to provide an individualized approach to drain management after pancreaticoduodenectomy.

Abstract
Preoperative prediction of the postoperative pancreatic fistula risk is critical in the current era of minimally invasive pancreatic surgeries to tailor perioperative management, thereby minimizing postoperative morbidity. Pancreatic duct diameter can be readily measured by any routine imaging used to diagnose pancreatic disease. However, radiological evaluation of pancreatic texture, an important determinant of pancreatic fistula, has not been widely used to predict the risk of postoperative pancreatic fistula. Qualitative and quantitative assessment of pancreatic fibrosis and fat fraction provides the basis for predicting pancreatic texture. Traditionally computed tomography has been utilized in identifying and characterizing pancreatic lesions and background parenchymal pathologies. With the increasing utilisation of endoscopic ultrasound and magnetic resonance imaging for evaluating pancreatic pathologies, elastography is emerging as a promising tool for predicting pancreatic texture. Also, recent studies have shown that early surgery for chronic pancreatitis is associated with better pain relief and preservation of pancreatic function. Pancreatic texture assessment can allow early diagnosis of chronic pancreatitis, facilitating early intervention. The present review outlines the current evidence in utilizing various imaging modalities for determining the pancreatic texture based on different parameters and image sequences. However, multidisciplinary investigations using strong radiologic-pathologic correlation are needed to standardize and establish the role of these non-invasive diagnostic tools in predicting pancreatic texture.

Abstract
BACKGROUND After pancreatojejunostomy for pancreatic head resection, contrast-enhanced computed tomography sometimes reveals a hypoattenuated area at the pancreatojejunostomy site. The clinical impact of this hypoattenuated area, in terms of postoperative pancreatic fistula, is unknown. METHODS Among 309 patients undergoing pancreatic head resection with pancreatojejunostomy reconstruction at Osaka University Hospital from 2012 to 2020, 105 exhibited drain amylase levels over 3× the upper limit of normal. According to contrast-enhanced computed tomography on postoperative days 3-14, these patients were divided into two groups-evident hypoattenuated area group (≥ 5 mm; n = 46) and subtle hypoattenuated area group (< 5 mm; n = 59)-and evaluated for clinically relevant pancreatic fistula. RESULTS Clinically relevant pancreatic fistula was significantly more common with the evident hypoattenuated group (80.4%; 37/46) than the subtle hypoattenuated group (40.7%; 24/59) (P < 0.0001). Multivariate analysis identified four factors related to clinically relevant pancreatic fistula formation: male sex (P = 0.0230), main pancreatic duct diameter < 3 mm (P = 0.0007), operative time > 475 min (P = 0.0161), and evident hypoattenuated area group (P = 0.0050). Hypoattenuated area ≥ 5 mm was associated with clinically relevant pancreatic fistula (60.7% sensitivity; 79.6% specificity). CONCLUSION Evident hypoattenuated area on postoperative contrast-enhanced computed tomography was an independent risk factor for clinically relevant pancreatic fistula. Patients experiencing increased drain amylase levels may benefit from contrast-enhanced computed tomography assessment to predict clinically relevant pancreatic fistula formation.

Abstract
OBJECTIVE The aim of this study was to develop a classification system for pancreas-associated risk factors in pancreatoduodenectomy (PD). SUMMARY BACKGROUND DATA Postoperative pancreatic fistula (POPF) is the most relevant PD-associated complication. A simple standardized surgical reporting system based on pancreas-associated risk factors is lacking. METHODS A systematic literature search was conducted to identify studies investigating clinically relevant (CR) POPF (CR-POPF) and pancreas-associated risk factors after PD. A meta-analysis of CR-POPF rate for texture of the pancreas (soft vs not-soft) and main pancreatic duct (MPD) diameter was performed using the Mantel-Haenszel method. Based on the results, the International Study Group of Pancreatic Surgery (ISGPS) proposes the following classification: A, not-soft (hard) texture and MPD >3 mm; B, not-soft (hard) texture and MPD ≤3 mm; C, soft texture and MPD >3 mm; D, soft texture and MPD ≤3 mm. The classification was evaluated in a multi-institutional, international cohort. RESULTS Of the 2917 articles identified, 108 studies were included in the analyses. Soft pancreatic texture was significantly associated with the development of CR-POPF [odds ratio (OR) 4.24, 95% confidence interval (CI) 3.67-4.89, P < 0.01) following PD. Similarly, MPD diameter ≤3 mm significantly increased CR-POPF risk compared with >3 mm diameter MPDs (OR 3.66, 95% CI 2.62-5.12, P < 0.01). The proposed 4-stage system was confirmed in an independent cohort of 5533 patients with CR-POPF rates of 3.5%, 6.2%, 16.6%, and 23.2% for type A-D, respectively ( P < 0.001). CONCLUSION For future pancreatic surgical outcomes studies, the ISGPS recommends reporting these risk factors according to the proposed classification system for better comparability of results.

Abstract
BACKGROUND This study aimed to clarify the risk factors of clinically relevant pancreatic fistula after early drain removal with higher drain fluid amylase after pancreaticoduodenectomy. Clinical evaluation of early drain removal with a higher drain fluid amylase after pancreaticoduodenectomy has been controversial. The safety and effectiveness have not been sufficiently examined. METHODS Between 2015 and 2020, prophylactic surgical drains were prospectively removed on postoperative day 4 regardless of drain fluid amylase level in 364 study-eligible patients who underwent pancreaticoduodenectomy. Patients were classified according to drain fluid amylase on postoperative day 1: 281 patients with drain fluid amylase <4,000 U/L, and 83 patients with drain fluid amylase ≥4,000 U/L. RESULTS Clinically relevant pancreatic fistula occurred in 40 of 364 enrolled patients (11.0%). In the entire cohort, male, positive postoperative day 1 drain fluid culture, and postoperative day 1 drain fluid amylase ≥4,000 U/L were independent risk factors for clinically relevant pancreatic fistula after early drain removal. When stratifying by 4,000 U/L of postoperative day 1 drain fluid amylase, the rate of clinically relevant pancreatic fistula in postoperative day 1 drain fluid amylase <4,000 U/L was significantly lower than that in postoperative day 1 drain fluid amylase ≥4,000 U/L (4% vs 35%, P < .001) after early drain removal. Moreover, in postoperative day 1 drain fluid amylase <4,000 U/L, positive postoperative day 1 drain fluid culture did not develop clinically relevant pancreatic fistula after early drain removal. However, in postoperative day 1 drain fluid amylase ≥4,000 U/L, multivariate analysis clarified that positive postoperative day 1 drain fluid culture was the only independent risk factor of clinically relevant pancreatic fistula after early drain removal (odds ratio 26.27, 95% confidence interval 5.59-123.56, P = .001). CONCLUSION Positive drain fluid culture on postoperative day 1 might predict clinically relevant pancreatic fistula in early drain removal with a higher drain fluid amylase.

Abstract
A postoperative pancreatic fistula (POPF) is the main complication after cephalic pancreaticoduodenectomy (CPD). Unlike its prevention, the curative management of POPFs has long been poorly codified. This review seeks best practices for managing POPFs after CPD. The diagnosis of a POPF is based on two signs: (i) an amylase level in drained fluid more than 3 times the upper limit of the blood amylase level; and (ii) an abnormal clinical course. In the standardised definition of the International Study Group of Pancreatic Surgery, a purely biochemical fistula is no longer counted as a POPF and is treated by gradual withdrawal of the drain over at most 3 weeks. POPF risk can be scored using pre- and intraoperative clinical criteria, many of which are related to the quality of the pancreatic parenchyma and are common to several scoring systems. The prognostic value of these scores can be improved as early as Day 1 by amylase assays in blood and drained fluid. Recent literature, including in particular the Dutch randomised trial PORSCH, argues for early systematic detection of a POPF (periodic assays, CT-scan with injection indicated on standardised clinical and biological criteria plus an opinion from a pancreatic surgeon), for rapid minimally invasive treatment of collections (percutaneous drainage, antibiotic therapy indicated on standardised criteria) to forestall severe septic and/or haemorrhagic forms, and for the swift withdrawal of abdominal drains when the risk of a POPF is theoretically low and evolution is favourable. A haemorrhage occurring after Day 1 always requires CT angiography with arterial time and monitoring in intensive care. Minimally invasive treatment of a POPF (radiologically-guided percutaneous drainage or, more rarely, endoscopic drainage, arterial embolisation) should be preferred as first-line treatment. The addition of artificial nutrition (enteral via a nasogastric or nasojejunal tube, or parenteral) is most often useful. If minimally invasive treatment fails, then reintervention is indicated, preserving the remaining pancreas if possible, but the expected mortality is higher.

Abstract
Three-dimensional surgical simulation, already in use for hepatic surgery, can be used in pancreatic surgery. However, some problems still need to be overcome to achieve more precise pancreatic surgical simulation. The present study evaluates the performance of SYNAPSE VINCENT® (version 6.6, Fujifilm Medical Co., Ltd., Tokyo, Japan) in the semiautomated surgical simulation of the pancreatic parenchyma, pancreatic ducts, and peripancreatic vessels using an artificial intelligence (AI) engine designed with deep learning algorithms. One-hundred pancreatic cancer patients and a control group of 100 nonpancreatic cancer patients were enrolled. The evaluation methods for visualizing the extraction were compared using the Dice coefficient (DC). In the pancreatic cancer patients, tumor size, position, and stagewise correlations with the pancreatic parenchymal DC were analyzed. The relationship between the pancreatic duct diameter and the DC, and between the manually and AI-measured diameters of the pancreatic duct were analyzed. In the pancreatic cancer/control groups, the pancreatic parenchymal DC and pancreatic duct extraction were 0.83/0.86 and 0.84/0.77. The DC of the arteries (portal veins/veins) and associated sensitivity and specificity were 0.89/0.88 (0.89/0.88), 0.85/0.83 (0.85/0.82), and 0.82/0.81 (0.84/0.81), respectively. No correlations were observed between pancreatic parenchymal DC and tumor size, position, or stage. No correlation was observed between the pancreatic duct diameter and the DC. A positive correlation (r = 0.61, p<0.001) was observed between the manually and AI-measured diameters of the pancreatic duct. Extraction of the pancreatic parenchyma, pancreatic duct, and surrounding vessels with the SYNAPSE VINCENT® AI engine assumed to be useful as surgical simulation.

Abstract
Clinically relevant postoperative pancreatic fistula (CR-POPF) has continued to compromise patient recovery post-pancreatectomy despite decades of research seeking to improve risk prediction and diagnosis. The current diagnostic criteria for CR-POPF requires elevated drain fluid amylase to present alongside POPF-related complications including infection, haemorrhage and organ failure. These worrying sequelae necessitate earlier and easily obtainable biomarkers capable of reflecting evolving CR-POPF. Drain fluid has recently emerged as a promising source of biomarkers as it is derived from the pancreas and hence, capable of reflecting its postoperative condition. The present review aims to summarise the current knowledge of CR-POPF drain fluid biomarkers and identify gaps in the field to invigorate future research in this critical area of clinical need. These findings may provide robust diagnostic alternatives for CR-POPF and hence, to clarify their clinical utility require further reports detailing their diagnostic and/or predictive accuracy.

Abstract
BACKGROUND Early stratification of postoperative pancreatic fistula according to severity and/or need for invasive intervention may improve outcomes after pancreaticoduodenectomy. This study aimed to identify the early postoperative variables that may predict postoperative pancreatic fistula severity. METHODS All patients diagnosed with biochemical leak and clinically relevant-postoperative pancreatic fistula based on drain fluid amylase >300 U/L on the fifth postoperative day after pancreaticoduodenectomy were identified from a consecutive cohort from Birmingham, UK. Demographics, intraoperative parameters, and postoperative laboratory results on postoperative days 1 through 7 were retrospectively extracted. Independent predictors of clinically relevant-postoperative pancreatic fistula were identified using multivariable binary logistic regression and converted into a risk score, which was applied to an external cohort from Verona, Italy. RESULTS The Birmingham cohort had 187 patients diagnosed with postoperative pancreatic fistula (biochemical leak: 99, clinically relevant: 88). In clinically relevant-postoperative pancreatic fistula patients, the leak became clinically relevant at a median of 9 days (interquartile range: 6-13) after pancreaticoduodenectomy. Male sex (P = .002), drain fluid amylase-postoperative day 3 (P < .001), c-reactive protein postoperative day 3 (P < .001), and albumin-postoperative day 3 (P = .028) were found to be significant predictors of clinically relevant-postoperative pancreatic fistula on multivariable analysis. The multivariable model was converted into a risk score with an area under the receiver operating characteristic curve of 0.78 (standard error: 0.038). This score significantly predicted the need for invasive intervention (postoperative pancreatic fistula grades B3 and C) in the Verona cohort (n = 121; area under the receiver operating characteristic curve: 0.68; standard error = 0.06; P = .006) but did not predict clinically relevant-postoperative pancreatic fistula when grades B1 and B2 were included (area under the receiver operating characteristic curve 0.52; standard error = 0.07; P = .802). CONCLUSION We developed a novel risk score based on early postoperative laboratory values that can accurately predict higher grades of clinically relevant-postoperative pancreatic fistula requiring invasive intervention. Early identification of severe postoperative pancreatic fistula may allow earlier intervention.

Abstract
BACKGROUND Although a soft pancreas is a widely-accepted reliable risk factor for postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD), there is no established preoperative evaluation of pancreatic texture. METHODS Two hundred thirty-seven patients who underwent PD with histological pancreatic assessment were retrospectively enrolled. The degree of fibrosis and fatty infiltration was scored histologically as seven grades and five grades, respectively. Computed tomography (CT) attenuation of the pancreas was measured on preoperative unenhanced CT images. Correlations between the CT attenuation of the pancreas and the histological pancreatic findings, and the development of POPF were analyzed. RESULTS The fibrosis grade was significantly higher for hard pancreas than for soft pancreas (p < 0.001), whereas the fatty infiltration grade was similar between the two types (p = 0.161). CT attenuation of the pancreas was inversely correlated with both fibrosis grade (Spearman's rank correlation coefficient ([r] = -0.609, p < 0.001) and fatty infiltration grade (r = -0.382, p < 0.001). Multivariate analysis showed that body mass index ≥25 kg/m2 (odds ratio [OR]: 5.64, p < 0.001) and fibrosis grade ≤2 (OR: 18.0, p < 0.001) were independent risk factors for clinically significant POPF. CONCLUSION Histological pancreatic texture can be evaluated with CT attenuation and might be helpful in preoperatively predicting the development of POPF after PD.

Abstract
BACKGROUND Pancreatic fistula remains the biggest problem in pancreatic surgery. We have previously reported a new pancreatojejunostomy method using an inter-anastomosis drainage (IAD) suction tube with Blumgart anastomosis for drainage of the pancreatic juice leaking from the branched pancreatic ducts. This study aimed to evaluate the postoperative outcomes of our novel method, in pancreatojejunostomy and investigate the nature of the inter-anastomosis space between jejunal wall and pancreas parenchyma. METHODS This retrospectively study consist of 282 pancreatoduodenectomy cases, including 86 reconstructions via the Blumgart method plus IAD (B + IAD group) and 196 cases reconstructed using the Blumgart method alone (B group). Postoperative outcomes and the amylase value and the volume of the drainage fluids were compared between the two groups. The IAD tube was placed to collect amylase-rich fluid from the inter-anastomosis space during operative procedure between the jejunal wall and pancreatic stump. RESULTS The daily IAD drainage volume and the amylase level was significantly higher in patients with a soft pancreas (vs hard pancreas; 16.5 vs. 10.0 mL/day, p = 0.012; 90,900 vs. 1634 IU/L, p < 0.001, respectively). The mean amylase value of IAD collection in 86 cases of B + IAD group was 63,100 IU/L. The incidence of clinically relevant pancreatic fistula grade B and C (23.2% vs. 23.0%, p = 0.55) and the hospital stay was similar between the groups (median 17 vs. 18 days, p = 0.55). In 176 patients with soft pancreas, the incidence of pancreatic fistula grade B and C (33.3% vs. 35.3%, p = 0.67) and the hospital stay was also similar between the groups (median 22.5 vs. 21 days, p = 0.81). CONCLUSIONS Positive effect of the IAD method observed in the pilot cases was not reproduced in the current study. IAD tube objectively demonstrated the existence of amylase-rich discharge at the anastomosis site, and countermeasures to eliminate this liquid are highly desired for preventing pancreatic fistula, especially in patients with soft pancreatic texture. Trial registration Retrospectively registered.

Abstract
BACKGROUND Drain management algorithms are based on studies that predict clinically relevant postoperative pancreatic fistula (CR-POPF) using drain fluid amylase level on POD1 (DFA1). These studies are focused on pancreaticoduodenectomy which is inherently different than distal pancreatectomy. Moreover, the change of DFA between POD1 and POD3 (ΔDFA) is underutilized despite its importance in predicting CR-POPF. We sought to generate a calculator that estimates the risk of CR-POPF following distal pancreatectomy. METHODS The 2014-2018 pancreas-targeted ACS-NSQIP database was used to identify patients who underwent elective distal pancreatectomy. Models to predict CR-POPF were constructed using DFA1 with/without ΔDFA. The fittest model was used to construct a calculator. RESULTS Out of 12,042 distal pancreatectomies, 692 patients met the study's inclusion criteria. The risk of CR-POPF was 15.9% in the included cohort versus 14.8% in the excluded one (P = 0.421). The predictors of the CR-POPF were age, operative time, DFA1, and ΔDFA. Adding ΔDFA decreased the Akaike's information criterion of the model (507.7 vs 544.7)-indicating a significantly better model fit-and improved the cross-validated area under the curve from 0.731 to 0.791. An easy-to-use calculator was created for surgeons to estimate the risk of CR-POPF based on the abovementioned variables. A sensitivity/specificity table was created at various cutoffs to direct clinical decision-making with respect to early drain removal. CONCLUSIONS This study highlights the importance of ΔDFA, in addition to DFA1, in predicting CR-POPF. The provided calculator will facilitate predicting CR-POPF and postoperative drain management following distal pancreatectomy.

Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) is a common and troublesome complication after pancreatoduodenectomy (PD). We conducted a systematic review and meta-analysis to identify the risk factors of CR-POPF after PD. METHODS We searched PubMed, EMBASE, and Cochrane Library databases for studies related to risk factors of CR-POPF after PD. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were extracted from the included studies, then a meta-analysis was conducted. If necessary, sensitivity analysis would be performed by changing the effect model or excluding 1 study at a time. Publication bias was assessed by funnel plot and Begg test and Egger test. RESULTS A total of 27 studies with 24,740 patients were included, and CR-POPF occurred in 3843 patients (incidence = 17%, 95% CI: 16%-19%). Male (OR = 1.56, 95% CI: 1.42-1.70), body mass index >25 kg/m2 (OR = 1.98, 95% CI: 1.23-3.18), pancreatic duct diameter <3 mm (OR = 1.87, 95% CI: 1.66-2.12), soft pancreatic texture (OR = 3.49, 95% CI: 2.61-4.67), and blood transfusion (OR = 3.10, 95% CI: 2.01-4.77) can significantly increase the risk of CR-POPF. Pancreatic adenocarcinoma (OR = 0.54, 95% CI: 0.47-0.61), vascular resection (OR = 0.57, 95% CI: 0.39-0.83), and preoperative chemoradiotherapy (OR = 0.68, 95% CI: 0.57-0.81) can significantly decrease the factor of CR-POPF. Diabetes mellitus was not statistically associated with CR-POPF (OR = 0.66, 95% CI: 0.40-1.08). However, the analysis of body mass index, pancreatic texture, and diabetes mellitus had a high heterogeneity, then sensitivity analysis was performed, and the result after sensitivity analysis showed diabetes mellitus can significantly decrease the risk of CR-POPF. There was no significant publication bias in this meta-analysis. CONCLUSIONS The current review assessed the effects of different factors on CR-POPF. This can provide a basis for the prevention and management of CR-POPF. Effective interventions targeting the above risk factors should be investigated in future studies for decreasing the occurrence of CR-POPF.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is a frequent complication after pancreaticoduodenectomy (PD). This study aimed to investigate the impact of Vater's ampullary carcinoma (VAC) on clinically relevant POPF (CR-POPF) in patients undergoing PD. METHODS Clinical data were gathered retrospectively from January 2018 to December 2020 for all patients undergoing PD. The univariate and multivariate analysis were used to identify independent risk factors of CR-POPF. A propensity score-matched (PSM) analysis at a ratio of 1:1 was performed to minimize bias from baseline characteristics between VAC and non-VAC groups. Main postoperative complications were compared between the two groups after PSM. RESULTS In 263 patients, 94 (35.7%) patients were diagnosed as VAC. CR-POPF occurred in 99 (37.6%) patients and VAC was identified as an independent risk factor of CR-POPF in multivariate logistic regression analysis (OR = 0.548, 95% CI = 0.327-0.920, P = 0.023). After PSM, there were similar baseline characteristics between the VAC and non-VAC group. Moreover, VAC group had a higher rate of CR-POPF (P = 0.025) and intra-abdominal infection (P = 0.015) compared to the non-VAC group. CONCLUSIONS In patients undergoing PD, VAC increases the risk of CR-POPF and several other postoperative complications.

Abstract
INTRODUCTION Of the possible complications after a cephalic duodenopancreatectomy (CPD), the clinically relevant postoperative pancreatic fistula (PPF) is the most important, especially in patients with pancreas of a soft consistency. The main objective of this work is to analyze the different postsurgical complications, with special emphasis on the rate of PPF on soft pancreas with a risk of moderate/high PPF, and its incidence between the two different types of sutures used by our group (classic vs reinforced duct-mucosa anastomosis [REDMA]). METHODS Retrospective observational study, between January 2017 and March 2020, of patients undergoing CPD in our unit after applying the inclusion and exclusion criteria. Analysis of preoperative, intraoperative factors and postoperative complications observed during follow-up. RESULTS Sample of 34 patients; 67.6% (n = 23) of them under the classic protocol and 32.4% (n = 11) with REDMA. The only post-surgical complication in which we obtained statistical repercussion, without differences between cases and controls in terms of the risk of FPP, in favor of the REDMA anastomosis is that of FPP. Thanks to this surgical innovation, both the complications from stage IIIb, according to the Clavien-Dindo classification, and the mean hospital stay have also been reduced with statistical significance. CONCLUSIONS When REDMA reduces the rate of PPF in patients with moderate/high surgical risk of it, we consider it to be a useful alternative to consider in the reconstruction of transit after CPD.

Abstract
BACKGROUND Drain fluid amylase is commonly used as a predictor of pancreatic fistula after pancreaticoduodenectomy (PD). This study aimed to determine the ideal cut-off value of drain fluid amylase on postoperative day 1 (DFA1) for predicting pancreatic fistula after pancreaticogastrostomy (PG). METHODS Prospective data of 272 consecutive patients undergoing PG between 2010 and 2020 was collected and analysed to determine the postoperative pancreatic fistula (POPF) risk factors. RESULTS The incidence of POPF was 143 cases (52.6%). The median DFA1 in patients with POPF was significantly higher than that of patients with NO-POPF (5483 versus 311, P < 0.001). DFA1 correlated with POPF in the area under the curve (AUC) of 0.84 (P < 0.001). When DFA1 was 2300 U/L, Youden index was the highest, with a sensitivity of 72.7% and a specificity of 82.9%. Logistic regression analysis showed that DFA1 ≥ 2300 U/L was an independent predictor of POPF (P < 0.001; OR: 12.855; 95% CI: 7.019-23.544). The AUC of DFA1 and clinically relevant postoperative pancreatic fistula (CR-POPF) was 0.674 (P < 0.001). CONCLUSION DFA1 ≥ 2300 U/L can be used as an independent predictor of POPF after PG. DFA1 ≥ 3000 U/L can predict the occurrence of CR-POPF, when DFA1 ≥ 3000 U/L, the patients should be observed closely active for complications.

Abstract
PURPOSE The aim of this study was to elucidate the association between pancreatic fistula (PF) and the sequential changes in the perioperative exocrine function after pancreatectomy. METHODS The subjects were 96 patients who underwent a 13C-trioctanoin breath test before and 1 month after pancreatectomy, between 2006 and 2018. We retrospectively compared the pre- and postoperative fat absorption levels between patients with PF (PF group; n = 17) and without PF (non-PF group; n = 79) using the breath test. RESULTS The preoperative level of 13C-trioctanoin absorption (%dose/h) was comparable between the non-PF and PF groups (36.5 vs. 36.9). In the non-PF group, 13C-trioctanoin absorption was significantly decreased after surgery in comparison to the preoperative setting (post-operative 28.5; pre-operative 36.5; p < 0.0001), whereas these values were comparable (post-operative 36.9; pre-operative 34.5; p = 0.129) in the PF group. Moreover, postoperative absorption in the PF group was significantly better than that in the non-PF group (34.5 vs. 28.5%, p = 0.0003). The maximum drain amylase level was significantly higher in patients with a 13C-trioctanoin absorption level (%dose/h) of ≥ 30 in comparison to patients with levels of < 30 (2502 vs. 398 U/L, p = 0.001). CONCLUSION PF did not exacerbate the pancreatic exocrine function in the early postoperative period, and the acceleration or preservation of the exocrine function after surgery may be an important cause of PF.

Abstract
Backgound: This study aimed to determine the usefulness of the Controlling Nutritional Status (CONUT) scorescore for predicting postoperative pancreatic fistula (POPF). PATIENTS AND METHODS Data from 108 consecutive pancreaticoduodenectomy cases performed at the Surgery Department of Iwakuni Clinical Center, from April 2008 to May 2018, were included. Preoperative patient data and postoperative complication data were collected. RESULTS Of the 108 patients (male=65; female=43; mean age=70 years), 41 (37.9%) had indication for pancreaticoduodenectomy due to pancreatic carcinoma. Grade B or higher POPF was diagnosed in 32 patients (29.6%). In the multivariate analysis, body mass index ≥22 kg/m2 [odds ratio (OR)=5.24; p=0.005], CONUT score ≥4 (OR=3.28; p=0.042), non-pancreatic carcinoma (OR=47.17; p=0.001), and a low computed tomographic contrast attenuation value (late/early ratio) (OR=4.39; p=0.029) were independent risk factors for POPF. CONCLUSION Patients with high CONUT score are at high risk for POPF. Preoperative nutritional intervention such as immunonutrition might help reduce the POPF risk in these patients.

Abstract
BACKGROUND Sarcopenia is closely associated with morbidity after pancreatic surgery. We investigated the impact of preoperative nutritional support and rehabilitation on patients undergoing pancreaticoduodenectomy. METHODS This was a retrospective analysis of 101 patients who underwent pancreaticoduodenectomy. Skeletal muscle (SM) loss was defined using the SM index (cutoff level: 42 cm2/m2 in men and 38 cm2/m2 in women). A total of 33 and 30 patients received preoperative nutrition and prehabilitation, respectively. The neutrophil-to-lymphocyte ratio (NLR), Prognostic Nutritional Index (PNI), and modified Glasgow Prognostic Score (mGPS) values were calculated during the first visit and immediately before surgery. RESULTS SM loss was present in 65 of 101 patients and was significantly correlated with female sex, older age, lower body mass index, and low PNI. Preoperative nutritional support and prehabilitation prevented the decrease in PNI values in patients with SM loss. The NLR significantly improved in patients with SM loss who received nutritional support and prehabilitation. In patients with SM loss, the lack of preoperative nutrition and prehabilitation was an independent risk factor for postoperative pancreatic fistula. CONCLUSIONS Preoperative nutritional support and prehabilitation may reduce the incidence of pancreatic fistula in patients with SM loss and improve the surgical outcomes of patients undergoing pancreaticoduodenectomy.

Abstract
Aim In order to find the risk factors of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) according to the latest definition and grading system of International Study Group of Pancreatic Surgery (ISGPS) (version 2016) and propose a nomogram for predicting POPF. Methods We conducted a retrospective analysis of 232 successive cases of PD performed at our hospital by the same operator from August 2012 to June 2020. POPF was diagnosed in accordance with the latest definition of pancreatic fistula from the ISGPS. The risk factors of POPF were analyzed by univariate and multivariate logistic regression analysis. A nomogram model to predict the risk of POPF was constructed based on significant factors. Results There were 18 cases of POPF, accounting for 7.8% of the total. Among them, 17 cases were classified into ISGPF grade B and 1 case was classified into ISGPF grade C. In addition, 35 cases were classified into biochemical leak. Univariate and multivariate analysis showed that hypertension, non-diabetes, no history of abdominal surgery, antecolic gastrojejunostomy and soft pancreas were independent risk factors of POPF. Based on significant factors, a nomogram is plotted to predict the risk of POPF. The C-index of this nomogram to assess prediction accuracy was 0.916 (P < 0.001) indicating good prediction performance. Conclusion Hypertension, non-diabetes, no history of abdominal surgery, antecolic gastrojejunostomy and soft pancreas were independent risk factors of POPF. Meanwhile, a nomogram for predicting POPF with good test performance and discriminatory capacity was constituted.

Abstract
BACKGROUND The efficacy of different types of preoperative biliary drainage for cholangiocarcinoma has been debated over the past two decades. Controversy concerning the use of percutaneous transhepatic biliary drainage (PTBD) versus endoscopic biliary drainage (EBD) still exists. This study aimed to compare the long-term outcomes between PTBD and EBD in patients with distal cholangiocarcinoma. METHODS Data of patients diagnosed with distal cholangiocarcinoma who underwent preoperative PTBD or EBD from January 1999 to December 2017 were analyzed retrospectively. Post-surgical outcomes, including the incidence of post-operative complications, peritoneal metastasis, disease-free survival, and overall survival, were analyzed. Survival analyses were also performed after propensity score matching in the PTBD and EBD groups. RESULTS The incidence of post-operative complications was similar in both groups. The 5-year estimated cumulative incidences for peritoneal metastasis were 14.7% and 7.2% in the PTBD and EBD groups, respectively (p = 0.192). The 5-year disease-free survival rates were 23.7% and 47.3% in the PTBD and EBD groups, respectively (p = 0.015). In the multi-variate analysis for overall survival, PTBD was an independent poor prognostic factor. The 5-year overall survival rates were 35.9% and 56.3% in the PTBD and EBD groups, respectively (hazard ratio 1.85, confidence interval 1.05-3.26, p = 0.035). The results after propensity score matching indicated a poorer prognosis in the PTBD group, with a 5-year survival rate of 35.9% in the PTBD group vs 56.0% in the EBD group (p = 0.044). CONCLUSION PTBD should be considered as a negative prognostic factor in distal cholangiocarcinoma patients.

Abstract
BACKGROUND Minimally invasive pancreaticoduodenectomy (MIPD), including laparoscopic pancreaticoduodenectomy (LPD) and robotic pancreaticoduodenectomy (RPD), is technically demanding because of pancreaticojejunostomy (PJ). Postoperative pancreatic fistula (POPF) is the most serious complication of MIPD and open pancreaticoduodenectomy (OPD). Contrary to expectations, conventional PJ in MIPD did not improve POPF rate and length of hospital stay. High POPF rates are attributed to technical issues encountered during MIPD, which include motion restriction and insufficient water tightness. Therefore, we developed wrapping double-mattress anastomosis, the Kiguchi method, which is a novel PJ technique that can improve MIPD. Herein, we describe the Kiguchi method for PJ in MIPD and compare the outcomes between this technique and conventional PJ in OPD. METHODS The current retrospective study included 83 patients in whom the complete obstruction of the main pancreatic duct by pancreatic tumors was absent on preoperative imaging. This research was performed from September 2016 to August 2020 at Fujita Health University Hospital. All patients were evaluated as having a soft pancreatic texture, which is the most important factor associated with POPF development. Briefly, 50 patients underwent OPD with conventional PJ (OPD group). Meanwhile, 33 patients, including 15 and 18 who had LPD and RPD, respectively, underwent MIPD using the Kiguchi method (MIPD group). After a 1:1 propensity score matching, 30 patients in the OPD group were matched to 30 patients in the MIPD group. RESULTS The patients' preoperative data did not differ. The grade B/C POPF rate was significantly lower in the MIPD group than in the OPD group (6.7% vs 40.0%, p = 0.002). The MIPD group had a significantly shorter median length of hospital stay than the OPD group (24 vs 30 days, p = 0.004). CONCLUSION The novel Kiguchi method in MIPD significantly reduced the POPF rate in patients without complete obstruction of the main pancreatic duct.

Abstract
Fistula following leaked pancreatico-enteric anastomosis is a common, potentially lethal complication of pancreaticoduodenectomy (PD). Early assessment and prediction of its occurrence can improve postoperative outcomes. Various perioperative factors were analyzed for its contribution to clinically relevant postoperative pancreatic fistula (crPOPF). Also, the difference in clinical outcomes of patients with and without fistula was studied. Sixty-seven patients undergoing PD for malignancies were analyzed during 3-year period in a dual-institutional study. Various preoperative, intraoperative, and postoperative factors were assessed. The incidence and severity of POPF and its association with the development of other post-PD complications were observed. Patients with and without POPF were divided into groups and compared with univariate and multivariate analyses, to identify significant contributing factors. Clinically relevant POPF was present in 20.9% cases. crPOPF contributed to delayed gastric emptying, albeit insignificant (p = 0.403), but was significantly associated with increased incidence of post-pancreatectomy hemorrhagic (p = 0.005) and infectious complications (p = 0.013). Soft pancreas (p = 0.024), intraoperative blood loss (p = 0.045), blood transfusion (p = 0.024), and fistula risk score (p = 0.001) were significant predictors of crPOPF. First postoperative day (POD1) drain fluid amylase (DFA) values at cut-off of 1336 U/L (AUC = 0.871; p < 0.001) significantly predicted crPOPF with good sensitivity and specificity. POD1 DFA was only factor significant on multivariate analysis (p = 0.014). There was no significant difference in overall survival between groups. crPOPF results in significant post-pancreatectomy hemorrhagic and septic complications, along with increased mortality. It can be accurately predicted by several preoperative and intraoperative factors. POD1 DFA can independently predict crPOPF development.

Abstract
Drain Amylase level are routinely determined to diagnose pancreatic fistula after Pancreatocoduodenectomy. Consensus is lacking regarding the cut-off value of amylase to diagnosis clinically relevant postoperative pancreatic fistulae (POPF). The present study proposes a model based on Amylase Value in the Drain (AVD) measured in the first three postoperative days to predict a POPF. Amylase cut-offs were selected from a previous published systematic review and the accuracy were validated in a multicentre database from 12 centres in 2 countries. The present study defined POPF the 2016 ISGPS criteria (3 times the upper limit of normal serum amylase). A learning machine method was used to correlate AVD with the diagnosis of POPF. Overall, 454 (27%) of 1638 patients developed POPF. Machine learning excluded a clinically relevant postoperative pancreatic fistulae with an AUC of 0.962 (95% CI 0.940-0.984) in the first five postoperative days. An AVD at a cut-off of 270 U/L in 2 days in the first three postoperative days excluded a POPF with an AUC of 0.869 (CI 0.81-0.90, p < 0.0001). A single AVD in the first three postoperative days may not exclude POPF after pancreatoduodenectomy. The levels should be monitored until day 3 and have two negative values before removing the drain. In the group with a positive level, the drain should be kept in and AVD monitored until postoperative day five.

Abstract
BACKGROUND Pancreaticoduodenectomy (PD) has recently been improved due to its increased safety. However, postoperative pancreatic fistula (POPF) remains a lethal complication of PD. Identifying novel clinicophysiological risk factors for POPF during the early post-PD period would help improve patient morbidity and mortality. Therefore, this retrospective study aimed to evaluate possible risk factors during the early postoperative period after pancreaticoduodenectomy (PD). METHODS Data from 349 patients who underwent PD between 2007 and 2012 were examined retrospectively. All patients were classified into 2 groups: group A, patients without fistulae or biochemical leaks (288 patients), and group B, those with grade B or C POPF (61 patients). Data on various clinicophysiological parameters, including serum and drain laboratory data, were collected. Univariate and multivariate analyses were performed to evaluate POPF predictors. A predictive nomogram was established for these results. RESULTS Univariate analysis showed that various serum and drain-related factors, such as white blood cell count, C-reactive protein levels, drain amylase (DAMY) levels, and drain lipase (DLIP) levels, were possible POPF risk factors. Multivariate analysis confirmed that postoperative day (POD) 1 DLIP levels (hazard ratio, 15.393; p = 0.037) and decreased rate (POD3/1) of DAMY levels (hazard ratio, 4.415; p = 0.028) were independent risk factors. Further, POD1 DLIP levels and decreased rate of DAMY levels were significantly lower in group A than in group B. The accuracy of nomogram was 0.810. CONCLUSIONS POD1 DLIP levels (> 245 U/mL) and decreased rate of DAMY levels (> 0.44) were POPF risk factors, making them possible biomarkers for POPF.

Abstract
PURPOSE This study aimed to establish a reliable criterion for early drain removal after pancreaticoduodenectomy (PD) based on predictive factors of clinically relevant postoperative pancreatic fistula (CR-POPF) available on postoperative day 3 (POD3). METHODS A total of 300 consecutive patients who underwent PD with pancreaticojejunostomy at our hospital from 2011 to 2015 were analyzed retrospectively. CR-POPF was defined as POPF grade B or C according to the definition by ISGPF. Clinicopathological factors available on or before POD3 were analyzed to identify predictors of CR-POPF. Using obtained predictors, we developed a criterion for no CR-POPF and internally validated its relevance in 100 consecutive patients. RESULTS The incidence rates of CR-POPF, severe complications (Clavien-Dindo ≥ grade IIIa), and postoperative mortality were 35%, 9.6%, and 0.3%, respectively. Multivariate analysis showed that drain amylase (d-AMY) levels ≥ 350 IU/l on POD3, C-reactive protein (CRP) levels ≥ 14 mg/dl on POD3, preoperative endoscopic retrograde biliary drainage, and no portal vein resection were significant predictors of CR-POPF. Using the strongest predictors (i.e., d-AMY and CRP), we established a criterion for no CR-POPF: d-AMY levels < 350 IU/l and CRP levels < 14 mg/dl on POD3. The incidence rates of CR-POPF were 6%, 38%, and 88% in patients who fulfilled both of (n = 149), each of (n = 74), and none of (n = 77) the two factors, respectively. In the internal validation cohort, the positive predictive value of CR-POPF was 89%. CONCLUSIONS A simple two-factor criterion available on POD3 after PD has a reliable predictive ability. In patients who fulfill this criterion, early drain removal is considered safe.

Abstract
Objective
Postoperative pancreatic fistula (POPF) is one of the severe complications that develop after pancreaticoduodenectomy (PD). This study aimed to assess the utility of preoperative clinicophysiologic findings as risk factors for POPF after PD.
Summary of Background Data
We enrolled 350 patients who underwent PD between 2007 and 2012 at Tokyo Women's Medical University.
Methods
In total, 350 patients who underwent PD between 2007 and 2012 were examined retrospectively. All patients were classified into 2 groups as follows: group A (no fistula/biochemical leak group, 289 patients) and group B (grade B/C of POPF group 61 patients). Variables, including operative characteristics, length of stay in hospital, morbidity, mortality, and data regarding preoperative clinicophysiologic parameters, were collected and analyzed as predictors of POPF for univariate and multivariate analyses.
Results
There were 213 male and 137 female patients. The mean age was 65.4 years (range, 21–87 years). Univariate analysis showed that sex (P = 0.047), amylase level (P = 0.032), prognostic nutritional index (PNI; P = 0.001), and C-reactive protein/albumin ratio (P = 0.005) were independent risk factors for POPF. In contrast, multivariate analysis showed that sex (P = 0.045) and PNI (P = 0.012) were independent risk factors for POPF.
Conclusions
Our results show that PNI (≤48.64 U/mL) and male sex were risk factors for POPF after PD, and especially, PNI can be suggested as an effective biomarker for POPF.

Abstract
PURPOSE Pseudoaneurysm (PA) after pancreaticoduodenectomy (PD) is a harmful complication due to postoperative pancreatic fistula. However, the preventive method for PA is unclear. This study aimed to assess the risk factors for PA after PD and to evaluate the clinical features of patients with PA. METHODS Medical records of 54 patients who underwent PD and developed clinically relevant postoperative pancreatic fistula (POPF) were retrospectively reviewed. We evaluated postoperative computed tomography (CT) findings, including the perianastomotic fluid collection (PFC) location on postoperative day 4. Perioperative findings and postoperative CT findings were compared between patients with and without PA after PD. RESULTS The PA group included nine patients (17%). The median postoperative day of diagnosis of PA was 17 (range, 7-33). The PA locations were the gastroduodenal artery stump (n = 3), dorsal pancreatic artery (DPA) stump from the common hepatic artery (n = 4), DPA stump from the replaced right hepatic artery (n = 1), and inferior pancreaticoduodenal artery stump (n = 1). The prevalence of falciform ligament wrap to the hepatic artery was lower (33% vs. 78%, p = 0.014) and superior PFC prevalence was higher (100% vs. 58%, p = 0.019) in the PA group than in the non-PA group. Superior PFC reached the dorsal part of the caudate lobe of the liver in all patients with PA. Furthermore, all PAs occurred at the arteries that could not be wrapped by the falciform ligament. CONCLUSION Prevention of superior PFC and falciform ligament wrapping may reduce PA occurrence after PD with clinically relevant POPF.

Abstract
Background Clinically relevant postoperative pancreatic fistula (CR-POPF) continues to be a major contributor to morbidity after pancreaticoduodenectomy (PD), but it remains unclear what risk factors can precisely predict the development of CR-POPF after laparoscopic pancreatoduodenectomy (LPD). We thus aimed to identify the risk factors for predicting CR-POPF after LPD. Methods A total of 388 consecutive patients who underwent LPD at our institution between July 2014 and December 2018 were identified. All data, including pre-, intra-, and postoperative risk factors associated with CR-POPF defined by the International Study Group of Pancreatic Fistula, were collected retrospectively. To evaluate the predictive performance of the risk factor models, areas under the receiver operating characteristic curve (ROC) were determined. Results CR-POPF was observed in 31 patients (8.0%) with significant association observed with body mass index (BMI), visceral fat area (VFA), subcutaneous fat area (SFA), total fat area (TFA), intra-abdominal fat thickness, main pancreatic duct width, soft pancreatic texture, operative time, underlying pathology, and albumin (Alb) on postoperative days (POD) 1–3. Multivariate analyses revealed that VFA >82 cm2 [odds ratio (OR) =11.088; P=0.029], main pancreatic duct width <3 mm (OR =7.701; P=0.001), soft pancreatic texture (OR =12.543; P=0.022), and operative time >320 min (OR =6.061; P<0.001) were independent risk factors for CR-POPF after LPD. Areas under the ROC curve (AUC) analysis revealed the pancreatic texture was the strongest single predictor (AUC =0.854) of CR-POPF, and pancreatic texture + pancreatic duct width was the best two-predictor model (AUC =0.904). Meanwhile, our findings indicated an association between the TFA >221 cm2 (OR =8.637; P=0.001) and VFA >82 cm2 (OR =7.009; P<0.001) with soft pancreatic texture. Conclusions Soft pancreatic texture, VFA >82 cm2, main pancreatic duct width <3 mm, and operative time >320 min were independent predictive risk factors of CR-POPF for LPD.

Abstract
INTRODUCTION A soft remnant texture of the pancreas is commonly accepted as a risk factor for postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD). However, its assessment is subjective. The aim of this study was to evaluate the significance of intraoperative amylase level of the pancreatic juice as a risk factor of POPF after PD. METHOD This study included 75 patients who underwent PD between November 2014 and April 2020 at Jikei University Hospital. We investigated the relationship between pancreatic texture, intraoperative amylase level of pancreatic juice, results of the pathological evaluations, and the incidence of POPF. RESULTS Twenty-three patients (31%) developed POPF. The significant predictors of POPF were non-ductal adenocarcinoma (p < 0.01), soft pancreatic remnant (p < 0.01), high intraoperative blood loss (p < 0.01), high intraoperative amylase level of pancreatic juice (p < 0.01), and low pancreatic fibrosis (p < 0.01). Multivariate analysis revealed that the significant independent predictors of POPF were high intraoperative blood loss (p < 0.01) and high intraoperative amylase level of pancreatic juice (p = 0.02). Receiver operating characteristic (ROC) analysis showed that the cut-off value for the intraoperative amylase level of pancreatic juice was 2.17 × 105 IU/L (area under the curve = 0.726, sensitivity = 95.7%, and specificity = 50.0%) CONCLUSIONS: The intraoperative amylase level of pancreatic juice is a reliable objective predictor for POPF after PD.

Abstract
INTRODUCTION Of the possible complications after a cephalic duodenopancreatectomy (CPD), the clinically relevant postoperative pancreatic fistula (PPF) is the most important, especially in patients with pancreas of a soft consistency. The main objective of this work is to analyze the different postsurgical complications, with special emphasis on the rate of PPF on soft pancreas with a risk of moderate/high PPF, and its incidence between the two different types of sutures used by our group (classic vs reinforced duct-mucosa anastomosis [REDMA]). METHODS Retrospective observational study, between January 2017 and March 2020, of patients undergoing CPD in our unit after applying the inclusion and exclusion criteria. Analysis of preoperative, intraoperative factors and postoperative complications observed during follow-up. RESULTS Sample of 34 patients; 67.6% (n = 23) of them under the classic protocol and 32.4% (n = 11) with REDMA. The only post-surgical complication in which we obtained statistical repercussion, without differences between cases and controls in terms of the risk of FPP, in favor of the REDMA anastomosis is that of FPP. Thanks to this surgical innovation, both the complications from stage IIIb, according to the Clavien-Dindo classification, and the mean hospital stay have also been reduced with statistical significance. CONCLUSIONS When REDMA reduces the rate of PPF in patients with moderate/high surgical risk of it, we consider it to be a useful alternative to consider in the reconstruction of transit after CPD.

Abstract
BACKGROUND To clarify whether double-volume peritoneal lavage can decrease the risk of clinically relevant postoperative pancreatic fistula after pancreaticoduodenectomy. MATERIALS AND METHODS Forty-nine patients who underwent pancreaticoduodenectomy and intraoperative peritoneal lavage using 6000 mL of saline before abdominal closure were studied retrospectively. Bacterial cultures of the lavage fluid were taken twice, after irrigation using 3000 mL of saline and then after an additional 3000 mL of saline. Bacterial culture of the drainage fluid was taken on day 1, and the relationship between the results of bacterial cultures and clinically relevant postoperative pancreatic fistula was examined. RESULTS Double amount of peritoneal lavage significantly decreased the incidence of positive bacterial cultures than single amount of peritoneal lavage (45% vs. 29%, P < .05). Multivariate analysis showed that positive bacterial culture of drainage fluid on day 1 and main pancreatic duct size (<3 mm) were independent risk factors for clinically relevant postoperative pancreatic fistula. A positive bacterial culture of the final lavage fluid and preoperative biliary drainage were independent factors related to a positive bacterial culture on day 1. DISCUSSION A positive bacterial culture on day 1 is an independent risk factor for clinically relevant postoperative pancreatic fistula during pancreaticoduodenectomy. Double-volume intraperitoneal lavage may be effective for reducing the incidence of clinically relevant postoperative pancreatic fistula.

Abstract
Postoperative pancreatic fistula (POPF) is a common complication following pancreaticoduodenectomy (PD). However, risk factors for this complication remain controversial. We conducted a retrospective analysis of 107 patients who underwent PD. POPF was diagnosed in strict accordance with the definition of the 2016 update of pancreatic fistula from the International Study Group on Pancreatic Fistula (ISGPF). Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for POPF. A total of 19 (17.8%) subjects of pancreatic fistula occurred after PD, including 15 (14.1%) with grade B POPF and 4 (3.7%) with grade C POPF. There were 33 (30.8%) patients with biochemical leak. Risk factors for POPF (grade B and C) were larger area of visceral fat (odds ratio [OR], 1.40; p = 0.040) and pathology other than pancreatic adenocarcinoma or pancreatitis (OR, 12.45; p = 0.017) in the multivariate regression analysis. This result could assist the surgeon to identify patients at a high risk of developing POPF.

Abstract
BACKGROUND Majority of predictors of postoperative pancreatic fistula (POPF) use intraoperative variables. We aimed to study the role of preoperative ultrasound shear wave elastography (USWE) to predict POPF. METHODS The consecutive patients who underwent pancreaticoduodenectomy (PD) between January 2019 to March 2020 were prospectively enrolled. All patients underwent USWE assessment at the pancreatic neck level. Intraoperative variables including pancreatic texture, pancreatic duct diameter, blood loss and histological grading of fibrosis were also recorded. Associations between USWE and intraoperative variables and histological grading with the development of POPF were analyzed. RESULTS Of the 62 patients assessed, 50 patients (mean age: 53 ± 14 years; 31 males) were included. POPF and clinically relevant POPF (CRPOPF) were observed in 22 (44%) and 7 (14%) patients respectively. Soft pancreas was an independent predictor of CRPOPF (p = 0.04). The mean USWE valve was significantly lower in patients with CRPOPF as compared to no CRPOPF (9.7 Kpa vs. 12.8Kpa, p = 0.016). At receiver operating characteristic curve analysis, USWE value of 12.65Kpa yielded sensitivity and specificity of 100% and 47%, respectively, for prediction of CRPOPF. USWE showed significant correlation with intraoperative pancreatic texture (Spearman's rank correlation coefficient (ρ) = 0.565, p = 0.001). CONCLUSION USWE helps in preoperative prediction of CRPOPF. This may further help to customize management strategy in high risk patients.

Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) is a major complication of pancreatoduodenectomy (PD). A pancreatic stent is usually used for drainage of the pancreatic duct, but the best type of the stent remains unclear. The aim of this study was to investigate perioperative factors and their influence on the risk of CR-POPF following PD. METHODS From 2006 to 2019, the records of 246 patients who underwent PD were retrospectively reviewed, and the relationship between perioperative factors including type of pancreatic stent and CR-POPF was investigated. External or internal pancreatic stents were used for drainage of the pancreatic duct, and the internal stent was inserted 1 cm into the jejunum to decrease stent obstruction. RESULTS External and internal pancreatic stents were used in 137 and 109 patients, respectively. Multivariate analysis revealed that the diameter of the main pancreatic duct (odds ratio = 0.292, 95% confidence interval = 0.140-0.605, P = 0.001), diagnosis (odds ratio = 3.359, 95% confidence interval = 1.498-7.693, P = 0.003), and type of pancreatic stent (odds ratio = 0.435, 95% confidence interval = 0.203-0.934, P = 0.033) were independent factors related to CR-POPF after PD. Internal stent was associated with a low rate of CR-POPF (P < 0.001) and short postoperative hospital stay (P < 0.001) compared to external stent. CONCLUSION A short pancreatic internal stent could decrease the incidence of CR-POPF.

Abstract
BACKGROUND Many studies have explored factors relating to post-operative pancreatic fistula (POPF); however, the original definition (All-POPF) was revised to include only 'clinically relevant' (CR) POPF. This study identified variables associated with the two International Study Group on Pancreatic Surgery definitions to identify which variables are more strongly associated with CR-POPF. METHODS A systematic review identified all studies reporting risk factors for POPF (using both International Study Group on Pancreatic Fistula definitions) following pancreatoduodenectomy. The primary outcome was factors associated with CR-POPF. Meta-analyses (random effects models) of pre-, intra- and post-operative factors associated with POPF in more than two studies were included. RESULTS Among 52 774 patients All-POPF (n = 69 studies) and CR-POPF (n = 53 studies) affected 27% (95% confidence interval (CI95% ) 23-30) and 19% (CI95% 17-22), respectively. Of the 176 factors, 24 and 17 were associated with All- and CR-POPF, respectively. Absence of pre-operative pancreatitis, presence of renal disease, no pre-operative neoadjuvant therapy, use of post-operative somatostatin analogues, absence of associated venous or arterial resection were associated with CR-POPF but not All-POPF. CONCLUSION In conclusion this study demonstrates wide variation in reported rates of POPF and that several risk factors associated with CR-POPF are not used within risk prediction models. Data from this study can be used to shape future studies, research and audit across ethnic and geographic boundaries in POPF following pancreatoduodenectomy.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains a prominent complication following pancreatic cancer resections. The primary aim of this study was to evaluate the histological changes that occur in the pancreas due to neoadjuvant therapy (NAT) by comparing the acinar, collagen and fat scores in resected PDAC specimens of patients who did and did not receive NAT. Secondary aims included (1) the difference in rates of POPF in PDAC patients who received NAT versus upfront resection; and (2) the association between acinar/collagen/fat scores and the development of POPF. METHODS Consecutive patients who underwent pancreaticoduodenectomy for PDAC, with and without NAT were included for analysis. Acinar, collagen and fat scores were determined from histology slides of the pancreatic resection margin. RESULTS One hundred and thirty-four patients were included. There was a significant decrease in the median acinar score (48 vs 23, p = 0.003) and increase in the collagen score (28 vs 50, p = 0.011) for patients who received NAT and a significant correlation with the number of cycles of NAT. This study found no statistical difference between NAT and the development of POPF. CONCLUSION The use of NAT in the treatment of PDAC changes the composition of the pancreas.

Abstract
BACKGROUND Although bile duct resection (BDR) in addition to pancreaticoduodenectomy (PD) is considered a surgical approach in patients with middle-third cholangiocarcinoma (MCC), available prognostic information after BDR remains very limited. The aim of this study was to reappraise BDR from the viewpoint of surgical oncology. METHODS Patients who underwent BDR or PD for MCC between 2001 and 2010 at 32 Japanese hospitals were included. Clinicopathological factors were retrospectively compared according to surgical procedure to identify a subset cohort who benefited most from BDR. RESULTS During the study, 92 patients underwent BDR (n = 38) or PD (n = 54). BDR was characterized by a shorter operation time, less blood loss, less frequent complications, and lower mortality, than PD. The incidence of positive surgical margins was 26.3% versus 5.6% (P = 0.007). The survival rate after BDR was significantly worse than that after PD: 38.8% versus 54.8% at 5 years (P = 0.035), and BDR was independently associated with deteriorated survival [hazard ratio (HR), 1.76; P = 0.023] by multivariable analysis. In the BDR group, tumor length < 15 mm (HR, 3.38; P = 0.017) and ductal margin length ≥ 10 mm (HR, 2.54; P = 0.018) were independent positive prognostic factors. Stratified by these two favorable factors, the 5-year survival rate was 63.0% in patients with 1/2 factors and 6.7% in those with 0 factors (P < 0.001). CONCLUSION In patients with MCC, BDR provided a better short-term and a worse long-term outcome than PD. However, patient selection using tumor length and ductal margin length may allow a favorable survival probability even after BDR.

Abstract
Postoperative pancreatic fistula (PF) is a major and serious complication that occurs after pancreaticoduodenectomy (PD). The aim of the current study was to evaluate the use of a novel biomarker, presepsin, for predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after PD. A prospective pilot study was conducted using 30 consecutive patients who underwent PD. Risk factors and candidates for predictive biomarkers for CR-POPF were statistically analyzed. CR-POPF (grade B and C; determined according to the guidelines of the International Study Group of Pancreatic Fistula) occurred in 15 patients (50%). Univariate analysis revealed that certain underlying conditions, including non-pancreatic cancer, smaller pancreatic ducts and soft pancreas texture were significantly associated with CR-POPF (P=0.005, P=0.004 and P=0.014, respectively). Furthermore, on day 1 post surgery (POD1), white blood cell count (P=0.040), levels of serum amylase (P=0.002) and serum presepsin (P=0.012), and the concentration of presepsin in drainage fluid (P<0.001) were significantly increased in CR-POPF compared with non-CR-POPF cases. Receiver operating characteristic curve analyses revealed that, on POD1, serum amylase and the concentration of presepsin in drainage fluid had an area under the curve value exceeding 0.8. A multivariate logistic regression analysis revealed that a higher concentration of presepsin in the drainage fluid was an independent predictive marker for CR-POPF (odds ratio, 14.503; 95% confidence interval, 1.750-120.229; P=0.013). To the best of our knowledge, the present study demonstrated for the first time that presepsin concentration in drainage fluid is a useful marker of CR-POPF after PD.

Abstract
BACKGROUND The aim of this study was to investigate the usefulness of the range of change in prognostic nutritional index (PNI) during the early postoperative period as a predictor of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy. METHODS Data were retrospectively analyzed for 192 patients who underwent pancreaticoduodenectomy. Univariate and multivariate logistic regression analyses were used to evaluate perioperative variables. PNIP3-Pre ratio represented the range of change in PNI from before surgery to postoperative day (POD) 3, PNIP1-Pre ratio represented the range of change in PNI from before surgery to POD 1, and PNIP3-P1 ratio represented the range of change in PNI from POD 1 to POD 3. RESULTS The area under the curve (AUC) for PNIP3-P1 for prediction of POPF following pancreaticoduodenectomy was 0.683 (P < 0.001), which was highest among PNI ratios and higher than PNI on POD 3. The AUC for serum amylase level on POD 1 was 0.704 (P < 0.001), which was superior to the corresponding AUC on POD 3. The AUC for the combination of PNIP3-P1 ratio and serum amylase level on POD 1 for prediction of POPF was higher than the AUC of either indicator alone (0.743, P < 0.001). The combination of PNIP3-P1 ratio and serum amylase level on POD 1 was an independent predictor of POPF following pancreaticoduodenectomy (P = 0.018). CONCLUSIONS The combination of the range of change in PNI from POD 1 to POD 3 and serum amylase levels on POD 1 may be useful for prediction of POPF following pancreaticoduodenectomy.

Abstract
OBJECTIVES Pancreatic fistula (PF) is one of the most common complications after pancreaticoduodenectomy (PD). The soft pancreatic texture is known to be an important predictive factor for PF after PD. However, its evaluation is dependent on the sense of touch by the operator during operation, thus not objective. The aim of this study was to investigate the relationship between mean elasticity via intraoperative ultrasound elastography and histological pancreatic hardness, as well as predictive factor of PF after PD. METHODS Forty-eight patients who underwent ultrasound elastography during PD and had pancreatic parenchyma histologically evaluated were included. RESULTS Pancreatic fistula was noted in 20 patients. There were significant differences in the histological pancreatic fibrosis rate between soft pancreas group (8.2%) and hard pancreas group (28.4%, P < 0.05) and in the mean elasticity between soft pancreas group (1.94 m/s) and hard pancreas group (3.17 m/s, P < 0.05). The mean elasticity was significantly correlated with pancreatic fibrosis rate (P < 0.05). A multivariate analysis revealed that the mean elasticity of less than 2.2 m/s was a significant predictor of PF after PD (P = 0.003). CONCLUSIONS Intraoperative ultrasound elastography could predict pancreatic texture objectively. The mean elasticity of less than 2.2 m/s was a significant predictor of PF after PD.

Abstract
BACKGROUND Several studies comparing internal and external stents have been conducted with the aim of reducing pancreatic fistula after PD. There is still no consensus, however, on the appropriate use of pancreatic stents for prevention of pancreatic fistula. This multicenter large cohort study aims to evaluate whether internal or external pancreatic stents are more effective in reduction of clinically relevant pancreatic fistula after pancreaticoduodenectomy (PD). METHODS We reviewed 3149 patients (internal stent n = 1,311, external stent n = 1838) who underwent PD at 20 institutions in Japan and Korea between 2007 and 2013. Propensity score matched analysis was used to minimize bias from nonrandomized treatment assignment. The primary endpoint was the incidence of clinically relevant pancreatic fistula. This study was registered on the UMIN Clinical Trials Registry (UMIN000032402). RESULTS After propensity score matched analysis, clinically relevant pancreatic fistula occurred in more patients in the external stents group (280 patients, 28.7%) than in patients in the internal stents group (126 patients, 12.9%) (OR 2.713 [95% CI, 2.139-3.455]; P < 0.001). In subset analysis of a high-risk group with soft pancreas and no dilatation of the pancreatic duct, clinically relevant pancreatic fistula occurred in 90 patients (18.8%) in internal stents group and 183 patients (35.4%) in external stents group. External stents were significantly associated with increased risk for clinically relevant pancreatic fistula (OR 2.366 [95% CI, 1.753-3.209]; P < 0.001). CONCLUSION Propensity score matched analysis showed that, regarding clinically relevant pancreatic fistula after PD, internal stents are safer than external stents for pancreaticojejunostomy.
