Abstract
Background Managing postoperative pancreatic fistula (POPF) presents a formidable challenge after pancreatoduodenectomy. Some centers consider pancreatic duct occlusion (PDO) in reoperations following pancreatoduodenectomy as a pancreas-preserving procedure, aiming to control a severe POPF. The aim of the current study was to evaluate the short- and long-term outcomes of employing PDO for the management of the pancreatic stump during relaparotomy for POPF subsequent to pancreatoduodenectomy. Methods Retrospective review of consecutive patients at Oslo University Hospital undergoing pancreatoduodenectomy and PDO during relaparotomy. Pancreatic stump management during relaparotomy consisted of occlusion of the main pancreatic duct with polychloroprene Faxan-Latex, after resecting the dehiscent jejunal loop previously constituting the pancreaticojejunostomy. Results Between July 2005 and September 2015, 826 pancreatoduodenectomies were performed. Overall reoperation rate was 13.2% (n = 109). POPF grade B/C developed in 113 (13.7%) patients. PDO during relaparotomy was performed in 17 (2.1%) patients, whereas completion pancreatectomy was performed in 22 (2.7%) patients. Thirteen (76%) of the 17 patients had a persistent POPF after PDO, and the time from PDO until removal of the last abdominal drain was median 35 days. Of the PDO patients, 13 (76%) patients required further drainage procedures (n = 12) or an additional reoperation (n = 1). In-hospital mortality occurred in one patient (5.9%). Five (29%) patients developed new-onset diabetes mellitus, and 16 (94%) patients acquired exocrine pancreatic insufficiency. Conclusions PDO is a safe and feasible approach for managing severe POPF during reoperation following pancreatoduodenectomy. A significant proportion of patients experience persistent POPF post-procedure, necessitating supplementary drainage interventions. The findings suggest that it is advisable to explore alternative pancreas-preserving methods before opting for PDO in the management of POPF subsequent to pancreatoduodenectomy.

Abstract
BACKGROUNDS Distal pancreatectomy fistula risk score (D-FRS) and DISPAIR-FRS has not been widely validated for predicting postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP). METHODS We retrospectively analysed 104 patients undergoing DP. The predictive value of the D-FRS and DISPAIR-FRS were compared. Risk factors associated with POPF were investigated by multivariate analysis. RESULTS Of the 104 patients, 23 (22.1%) were categorized into the POPF group (all grade B). The areas under the ROC (AUCs) of the D-FRS (preoperative), D-FRS (intraoperative), and DISPAIR-FRS were 0.737, 0.809, and 0.688, respectively. Stratified by the D-FRS (preoperative), the POPF rates in low-risk, intermediate-risk, and high-risk groups were 5%, 22.6%, and 36.4%, respectively. By the D-FRS (intraoperative), the POPF rates in low-risk, intermediate-risk, and high-risk groups were 8.8%, 47.1%, and 47.4%, respectively. By the DISPAIR-FRS, the POPF rates in low-risk, intermediate-risk, and extreme-high-risk groups were 14.8%, 23.8% and 62.5%, respectively. Body mass index and main pancreatic duct diameter were independent risk factors of POPF both in preoperative (P = 0.014 and P = 0.033, respectively) and intraoperative (P = 0.015 and P = 0.039) multivariate analyses. CONCLUSION Both the D-FRS (preoperative), D-FRS (intraoperative), and DISPAIR-FRS has good performance in POPF prediction after DP. The risk stratification was not satisfactory in current Asian cohort.

Abstract
Retroportal artery is one of the communicating arteries between the hepatic artery and the superior mesenteric artery, but it is often a small artery and usually unrecognized. We report a 60-year-old man that was successfully treated for postpancreatectomy hemorrhage from the retroportal artery with compression of the celiac trunk by the median arcuate ligament. Following the pancreaticoduodenectomy, the bloody discharge was discovered through the drainage catheter. We underwent transcatheter arterial embolization for the bleeding from the retroportal artery associated with a postoperative pancreatic fistula. Additionally, because a stenosis of the common hepatic artery was discovered, we consequently installed a stent-graft on the common hepatic artery to prevent the liver failure due to decreased hepatic blood flow.

Abstract
Introduction Central pancreatectomy (CP) represents an organ-preserving type of pancreatic resection. The procedure has been associated with improved long-term functional results, but increased postoperative morbidity rates, compared with the more radical resection types. The purpose of the present study was to present the outcomes of three consecutive CPs performed in our department. Materials and Methods Between January 2021 and January 2022, three patients (A, B, and C) were submitted to a CP in our department. Relevant patient data including data of the detailed preoperative assessment, operations notes, and recovery charts were prospectively collected and reviewed for all subjects. A scheduled follow-up, at the outpatient clinic, was conducted to assess the long-term functional results. Results The postoperative course of patient A, a 56-year-old male, was complicated by a grade C postoperative pancreatic fistula that required a reoperation. Patient B, a 66-year-old female, developed a biochemical leak that resolved spontaneously while patient C, a 64-year-old male, had a completely uneventful recovery. The length of hospital stay for the three patients was 24, 12, and 8 days, respectively. Regarding the long-term results, patient B was lost to follow-up while both patient A and C were followed up, as outpatients, 21 and 10 months after the operation. During follow-up, in patient A, we did not record the presence of symptoms consistent with pancreatic exocrine insufficiency, the hemoglobin A1C (HbA1C) levels were 7.1% while no additional medications were needed to be prescribed to maintain the glycemic control following surgery. In patient C, a significant weight loss was recorded (body mass index reduction of 11 kg/m 2 ) without however the presence of malabsorption-specific symptoms. The HbA1C levels were 7.7% and optimal glycemic control was achieved with oral antiglycemic agents alone. Conclusion CP should be regarded as a type of pancreatic resection with certain and very limited oncological indications. An approach of balancing the advantages out of the superior postoperative functional results with the drawbacks of the increased procedure-associated morbidity could highlight the patient group that could potentially experience benefits out of this limited type of resection.

Abstract
Background In this study, we aimed to determine the association between postoperative hyperamylasemia (POH) and clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreatoduodenectomy (PD). Methodology A prospective observational study of 140 consecutive PDs between March 2020 and March 2022 was conducted. POH was defined as an elevation in serum pancreatic amylase levels above the institutional upper limit of normal on postoperative day (POD) 1 (>100 U/L). CR-POPF was defined as the International Study Group of Pancreatic Surgery Grade B or C POPF. The primary outcome was the rate of CR-POPF in the study population. The trial was prospectively registered with Clinicaltrials.gov (NCT04514198). Results In our study, 93 (66.42%) patients had POH (serum amylase >100 U/L). CR-POPF developed in 48 (34.28%) patients: 40 type B and 8 type C. CR-POPF rate was 43.01% (40/93) in patients with POH compared to 17.02% (8/47) in patients without POH (p = 0.0022). Patients with POH had a mean serum amylase of 422.7 ± 358.21 U/L on POD1 compared to 47.2 ± 20.19 U/L in those without POH (p < 0.001). Serum amylase >100 U/L on POD1 was strongly associated with developing CR-POPF (odds ratio = 3.71; 95% confidence interval = 1.31-10.37) on logistic regression, with a sensitivity and specificity of 83.3% and 42.4%, respectively. Blood loss >350 mL, pancreatic duct size <3 mm, and elevated POD1 serum amylase >100 U/L were predictive of CR-POPF on multivariate analysis (p < 0.001). Conclusions An elevated serum amylase on POD1 may help identify patients at risk for developing POPF following PD.

Abstract
BACKGROUND Laparoscopic gastrectomy (LG) indications have been extended to advanced gastric cancer requiring expansive lymph node dissection. Despite the huge benefits of this minimally invasive surgery, major complications such as postoperative pancreatic fistula (POPF) remain a concern. With technical advances in surgical procedures, the treatment outcomes of gastric cancer surgery have improved. However, effective methods for preventing POPF have not yet been established. Herein, we examined the usefulness of polyglycolic acid (PGA) sheets for preventing POPF after LG. METHODS We retrospectively assessed 142 patients who underwent curative LG at our institution between January 2017 and August 2022. The 142 patients were divided into 2 groups; PGA group (n = 61): the site of lymph node dissection at the superior margin of the pancreas and pancreatic head was covered with PGA sheets, and nPGA group (n = 81): the site was not covered. We retrospectively compared the short-term surgical outcomes including POPF incidence. RESULTS There was no significant difference in the background factors between the 2 groups and in the incidence of Grade II or higher postoperative complications according to the Clavien-Dindo (CD) classification. However, the incidence of CD Grade II or higher POPF was significantly lower in the PGA group than in the nPGA group (.0% vs 2.3%, respectively, P = .007). CONCLUSIONS There was no POPF in any of the 61 patients in the PGA group. This outcome suggests that POPF incidence may be reduced by covering the lymph node dissection site with PGA sheets after LG.

Abstract
BACKGROUND Existing prediction models for clinically relevant postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD) lack discriminatory power or are too complex. This study aimed to develop a simple nomogram that could accurately predict clinically relevant POPF after PD. METHODS A high-volume, multicenter cohort of patients who underwent PD from the American College of Surgeons-National Surgical Quality Improvement Program database in the United States during 2014-2017 was used as the model training cohort ( n =3609), and patients who underwent PD from the Pancreatic Center of the National Cancer Center Hospital in China during 2014-2019 were used as the external validation cohort ( n =1347). The study used lasso penalized regression to screen large-scale variables, then logistic regression was performed to screen the variables and build a model. Finally, a prediction nomogram for clinically relevant POPF was established based on the logistic model, and polynomial equations were extracted. The performance of the nomogram was evaluated by receiver operating characteristic curve, calibration curve, and decision curve analysis. RESULTS In the training and validation cohorts, there were 16.7% (601/3609) and 16.6% (224/1347) of patients who developed clinically relevant POPF, respectively. After screening using lasso and logistic regression, only six predictors were independently associated with clinically relevant POPF, including two preoperative indicators (weight and pancreatic duct size), one intraoperative indicator (pancreatic texture), and three postoperative indicators (deep surgical site infection, delayed gastric emptying, and pathology). The prediction of the new nomogram was accurate, with an area under the curve of 0.855 (95% CI: 0.702-0.853) in the external validation cohort, and the predictive performance was superior to three previously proposed POPF risk score models (all P <0.001, likelihood ratio test). CONCLUSIONS A reliable lasso-logistic method was applied to establish a novel nomogram based on six readily available indicators, achieving a sustained, dynamic, and precise POPF prediction for PD patients. With a limited number of variables and easy clinical application, this new model will enable surgeons to proactively predict, identify, and manage pancreatic fistulas to obtain better outcomes from this daunting postoperative complication.

Abstract
Objective The aim of this study was to investigate the clinical efficacy of laparoscopic middle pancreatectomy in the treatment of benign and junctional tumors of the pancreas. Methods Retrospective analysis of basic data, tumor diameter, statistical analysis, and evaluation of efficacy-related indicators such as operative time, intraoperative bleeding, pathological findings, postoperative hospital stay, postoperative pancreatic fistula incidence, and pancreatic endocrine function was carried out on 17 patients diagnosed with benign or low-grade malignant tumors of the pancreas and laparoscopic middle pancreatic resection from January 2018 to January 2023 at the First Affiliated Hospital of Hunan Normal University. Results A total of 17 patients were screened. There were eight males and nine females; mean age was 42.8 ± 17.4 years (range: 15-69 years); BMI was 22.6 ± 2.5 kg/m2 (range: 18.4-27.5 kg/m2), and the tumor size was 3.4 ± 1.2 cm (range: 1.5-5.5 cm). Preoperative glycan antigen CA19-9 was negative and CA125 was negative. Surgical time was 393.2 ± 57.9 min; intraoperative bleeding was 211.7 ± 113.9 ml; tumor diameter size was 3.4 ± 1.2 cm; postoperative admission time was 19.4 ± 7.6 days; postoperative pancreatic fistula (POPF) grading was 17 cases, including nine cases of A-grade fistula, three cases of B-grade fistula, and none of C-grade fistula; postoperative pathology results were five cases of plasmacytoma, three cases of mucinous cystadenoma, four cases of SPN (solid pseudopapillary neoplasm), one case of Intraductal Papillary Mucinous Neoplasm (IPMN), three cases of pancreatic Neuroendocrine Neoplasm (pNEN), one case of inflammatory myofibroblastic osteoblastoma. All cases did not develop pancreatic origin diabetes or exacerbation of previous diabetes, and no cases presented symptoms of exocrine insufficiency such as dyspepsia and diarrhea. Conclusion Laparoscopic middle pancreatectomy is safe and feasible in the treatment of benign or low-grade malignant tumors in the body of the pancreatic neck and is not accompanied by increased risk of intraoperative and postoperative complications and endocrine dysfunction of the pancreas.

Abstract
OBJECTIVES The vascular supply to the neck and body of the pancreas is highly variable. The dorsal pancreatic artery is the dominant artery feeding this area. The aim of this study was to describe the vascular supply of postresection pancreatic remnants after pancreaticoduodenectomy. Patients with hazardous anatomical arrangement may be at a higher risk of postresection remnant ischemia and postoperative pancreatic fistula development. METHODS The modified Whipple procedure was performed on 20 cadaveric donors. The macroscopic anatomical supply of the postresection pancreatic remnant of each donor was evaluated. RESULTS The arterial supply of the postresection remnant was highly variable. In 30% of cases (6/20), the dorsal pancreatic artery was cut during the pancreatoduodenectomy or it was missing. In these cases, the area of the pancreaticojejunostomy construction was fed only through anastomoses between the transverse pancreatic artery and the pancreatic branches of the splenic artery. CONCLUSIONS In 30% of cases, the arterial supply of the postresection pancreatic remnant was dependent on inconstant intraparenchymal arterial anastomoses. These patients may be at a higher risk of postoperative pancreatic fistula development.

Abstract
Introduction Postoperative pancreatic fistula (POPF) is a critical complication occurring with a high incidence after distal pancreatectomy. To minimize the risk of POPF, we developed an innovative pancreas ligation device capable of closing the pancreatic stump without causing traumatic injury to the pancreatic duct and artery. We conducted an ex vivo follow-up study to compare the pressure resistance of the pancreas ligation device with that of a regular linear stapler. Materials and methods The pancreases were excised from 20 pigs and divided into two groups: ligation group (n = 10) and stapler group (n = 10). Distal pancreatectomy was performed, and the pancreatic stump was closed using either a pancreas ligation device or a regular linear stapler. The main pancreatic duct was cannulated with a 4-French catheter connected to a cannula and syringe filled with contrast medium. Using fluoroscopy detection, pressure resistance was defined as the maximum pressure without leakage from the pancreatic stump. Results No significant differences were found between the two groups regarding sex, age, body weight, or pancreatic thickness. In the ligation group, no leakage was observed at the stump in any pancreas. However, in the stapler group, six of 10 pancreases showed leakage at the staple line or into the parenchyma. Pressure resistance was significantly higher in the ligation group than in the stapler group (median: 42.8 vs. 34.3 mmHg, P = 0.023). Conclusions These findings suggest the effectiveness of a pancreas ligation device in reducing the incidence of POPF after distal pancreatectomy. Our ligation device is expected to be a useful alternative to a linear stapler for pancreatic stump closure.

Abstract
BACKGROUND/AIM The impact of perioperative fluid management on postoperative morbidity after pancreaticoduodenectomy (PD) remains uncertain. This study aimed to investigate the independent association between perioperative fluid balance (FB) and clinically relevant postoperative pancreatic fistula (POPF) in PD patients. PATIENTS AND METHODS A total of 243 consecutive open PD patients were included. Intra- and postoperative FB until postoperative day 3 were calculated, and their predictive performance for POPF was assessed using receiver operating characteristic (ROC) analysis. Propensity score (PS) was estimated as the probability of having higher FB, and factors associated with POPF were identified using crude and PS-adjusted logistic regression models. RESULTS POPF occurred in 60 patients (24.7%). ROC analysis showed the highest predictive value for total FB on postoperative days 1 and 2, with a cut-off value of 1,585 ml (area under the ROC curve=0.74). Patients with FB ≥1,585 ml had a significantly higher POPF rate (48.3%) compared to those with lower FB (11.0%, PS-adjusted p<0.001). Male sex, body mass index ≥25 kg/m2, non-pancreatic ductal adenocarcinoma, biliary drainage, main pancreatic duct diameter <3 mm, and higher FB showed significant associations with POPF in crude univariate analysis. Higher FB remained a significant factor in both crude multivariate and PS-adjusted analysis [crude multivariate: odds ratio (OR)=8.0; PS-adjusted univariate: OR=4.2; PS-adjusted multivariate: OR=6.1, all p<0.001]. CONCLUSION Higher early postoperative FB, a potentially modifiable factor, may be independently associated with increased risk of POPF in PD patients.

Abstract
BACKGROUND/AIM Postoperative pancreatic fistula (POPF) may cause severe complications. In this study, risk factors for postoperative pancreatic fluid leakage after pancreaticoduodenectomy (PD) were investigated, with a particular focus on preoperative pancreatic exocrine function and pathological evaluations of the resected pancreas. PATIENTS AND METHODS A total of 67 patients underwent the N-benzoyl-L-tyrosyl-para-aminobenzoic acid (BT-PABA) test and PD in our department between June 2003 and March 2018. The endpoint was the development of POPF. Patients' clinical characteristics, preoperative test results, surgery-related parameters, and pathological evaluations of the resected samples were investigated. Preoperative pancreatic exocrine function was evaluated by the BT-PABA test, and the proportion of residual acinar tissue and the fibrosis rate of the resected pancreatic tissue were assessed. RESULTS 17 (25.4%) patients with Grade B and C POPF were compared with 50 patients without POPF. On univariate analysis, pancreatic carcinoma (p=0.028), BT-PABA test results higher than 66.3% (p=0.030), and main pancreatic duct (MPD) diameter lower than 5.0 mm (p=0.006) were identified as risk factors for postoperative pancreatic fluid leakage. On multivariate analysis, pancreatic carcinoma (p=0.008), BT-PABA test results higher than 66.3% (p=0.036), MPD diameter lower than 5.0mm (p=0.029) were significant risk factors. BT-PABA test results have a moderate correlation with both the proportion of pancreatic acinar tissue (r=0.421, p=0.028) and the pancreatic fibrosis rate (r=-0.443, p=0.021). CONCLUSION The preoperative BT-PABA test results higher than 66.3% were an independent risk factor for POPF. This suggests that the development of POPF may be attenuated by diminished exocrine function with poor pancreatic fluid flow and the progression of fibrosis.

Abstract
OBJECTIVE Hemorrhage from the stump of the gastroduodenal artery (GDA) is a significant postoperative risk with pancreaticoduodenectomy (PD). Studies have shown that wrapping the GDA stump using the omentum or the falciform ligament can help prevent bleeding. We aimed to determine whether wrapping the GDA stump with the ligamentum teres hepatis (LTH) would reduce postoperative PD hemorrhage. METHODS We retrospectively reviewed data for 148 patients who underwent laparoscopic pancreatoduodenectomy (LPD) at our hospital from November 2015 to September 2021. We compared perioperative data from 63 LPD patients without wrapping of the GDA (unwrapped group) and 85 whose GDA stumps were wrapped (wrapped group). RESULTS There were no significant differences in the groups' baseline characteristics. The postoperative GDA stump bleeding incidence was significantly lower in the wrapped group than that in the unwrapped group (7.9% vs. 0, respectively). There was also no significant difference in the incidence of other complications (intra-abdominal infection, postoperative pancreatic fistula (POPF), biliary fistula, and gastrointestinal bleeding). CONCLUSION Using the LTH to wrap the GDA stump during LPD can reduce bleeding from the GDA stump but not the incidence of other complications.

Abstract
Introduction Pancreaticoduodenectomy (PD) is a complex procedure with a significant proportion of postoperative complications and improving but notable mortality. PD was the prototype procedure that initiated the lingering debate about the relationship of better operative outcomes when performed at higher-volume centers. This has not translated into practice. Impediments include the absence of a universally accepted definition of a high-volume center among others. Contrary evidence suggests equivalent outcomes for PD at low-volume centers when performed by experienced hepatobiliary surgeons. We reviewed our perioperative outcomes for PD from an earlier period as a low-volume center with an experienced team. Methods A longitudinal study of all PDs completed in our department between 2012 and 2017 was performed. Results A total of 28 PD were performed during this period. Pylorus-preserving PD was performed in 23 patients and classical PD in the remaining. A separate Roux-en-Y loop was used for high-risk pancreatic anastomosis in six cases. The mean patient age was 49.3±12.4 years. The male-to-female ratio was 1.3:1. Preoperative drainage procedures were carried out in 19 patients. The mean serum total bilirubin level was 3.98(±4.5) mg/dL. There was no 90-day mortality. Postoperative complications included wound infection in 10 (36.7%) and respiratory complications in 10 (36.7%) patients. Postoperative bleeding requiring intervention occurred in one patient, and two patients had an anastomotic leak (one pancreatojejunostomy (PJ) and one gastrojejunostomy (GJ)). Delayed gastric emptying (DGE) was noted in three (10.7%) patients. The mean length of hospital stay was 14±7 days. The median overall survival (OS) was 84 months. Conclusion Comparable early outcomes can be achieved at low-volume centers for patients undergoing PD with an experienced team, optimal patient selection, and the ability to rescue for complications.

Abstract
OBJECTIVE The objective of this study was to identify the indications for and report the outcomes of completion pancreatectomy (CPLP) in the postoperative course after pancreatoduodenectomy (PD). BACKGROUND CPLP may be considered or even inevitable for damage control after PD. METHODS A prospectively maintained database of all patients undergoing PD between 2001 and 2019 was searched for patients who underwent CPLP in the postoperative course after PD. Baseline characteristics, perioperative details, and outcomes of CPLP patients were analyzed and specific indications for CPLP were identified. RESULTS A total of 3953 consecutive patients underwent PD during the observation period. CPLP was performed in 120 patients (3%) after a median of 10 days following PD. The main indications for CPLP included postpancreatectomy acute necrotizing pancreatitis [n=47 (39%)] and postoperative pancreatic fistula complicated by hemorrhage [n=41 (34%)] or associated with uncontrollable leakage of the pancreatoenteric anastomosis [n=23 (19%)]. The overall 90-day mortality rate of all 3953 patients was 3.5% and 37% for patients undergoing CPLP. CONCLUSIONS Our finding that only very few patients (3%) need CPLP suggests that conservative, interventional, and organ-preserving surgical measures are the mainstay of complication management after PD. Postpancreatectomy acute necrotizing pancreatitis, uncontrollable postoperative pancreatic fistula, and fistula-associated hemorrhage are highly dangerous and represent the main indications for CPLP after PD.

Abstract
BACKGROUND The aim of this meta-analysis and systematic review was to evaluate the association between intraoperative bile cultures and postoperative complications of patients undergoing pancreaticoduodenectomy. METHODS A detailed literature search was performed from January 2015 to July 2022 in PubMed, Web of Science, Google Scholar, and EMBASE for related research publications. The data were extracted, screened, and graded independently. An analysis of pooled data was performed, and a risk ratio with corresponding confidence intervals was calculated and summarized. RESULTS A total of 8 articles were included with 1,778 pancreaticoduodenectomy patients who had an intraoperative bile culture performed. A systematic review demonstrated that some of the most common organisms isolated in a positive intraoperative bile culture were Enterococcus species, Klebsiella species, and E. coli. Four studies also showed that specific microorganisms were associated with specific postoperative complications (surgical site infection and intra-abdominal abscess). The postoperative complications that were evaluated for an association with a positive intraoperative bile culture were surgical site infections (risk ratio = 2.33, 95% confidence interval [1.47-3.69], P < .01), delayed gastric emptying (risk ratio = 1.23, 95% confidence interval [0.63-2.38], P = n.s.), 90-day mortality (risk ratio = 0.68, 95% confidence interval [0.01-52.76], P = n.s.), postoperative pancreatic hemorrhage (risk ratio = 1.70, 95% confidence interval [0.33-8.74], P = n.s.), intra-abdominal abscess (risk ratio = 1.70, 95% confidence interval [0.38-7.56], P = n.s.), and postoperative pancreatic fistula (risk ratio = 0.97, 95% confidence interval [0.72-1.32], P = n.s.). CONCLUSION The cumulative data suggest that a positive intraoperative bile culture has no association with predicting the postoperative complications of delayed gastric emptying, 90-day mortality, postoperative pancreatic hemorrhage, intra-abdominal abscess, or postoperative pancreatic fistula. However, the data also suggest that a positive intraoperative bile culture was associated with a patient developing a surgical site infection.

Abstract
Postoperative pancreatic fistula (POPF) is the most feared complication following pancreatic resection. Octreotide, a synthetic somatostatin analog, has been widely used by pancreatic surgeons worldwide after pancreatic resections, often as per surgeon's discretion, to prevent POPF especially in cases at high risk of developing POPF. We herein analyze the data available till date of the subject. A PubMed search with keywords "somatostatin OR octreotide OR somatostatin analogues AND postoperative pancreatic fistula" was made. Further filters were applied in the search "Clinical Trial, Meta-Analysis, Randomized Controlled Trial, Systematic Review, from 1990 - 2021," and the 68 results thus obtained were analyzed and included in this narrative review. There is considerable heterogeneity among the studies assessing the role of octreotide in the prevention of POPF making data comparison difficult, and hence results remain inconclusive. Most of the earlier studies used different definitions of POPF and other complications; included patients with varied pancreatic pathologies such as cancer, chronic pancreatitis, and benign lesions; surgical techniques such as pancreaticoduodenectomy, distal pancreatectomy, and other procedures; use of somatostatin and its analogs such as octreotide, lanreotide, pasireotide, and vapreotide; varied surgeon and institutional volume; and so on. Besides, pancreatic surgery is per se a complex surgical procedure and has its own inherent biases related to patient and the pancreas itself affecting the overall outcome. Data indicate favorable role of newer somatostatin analogs, and further studies are urgently needed. The question about the efficacy of prophylactic octreotide to reduce POPF after pancreaticoduodenectomy remains open to debate.

Abstract
OBJECTIVE To assesses the prevalence and severity of CAS in patients undergoing PD/total pancreatectomy and its association with major postoperative complications after PD. SUMMARY OF BACKGROUND DATA CAS may increase the risk of ischemic complications after PD. However, the prevalence of CAS and its relevance to major morbidity remain unknown. METHODS All patients with a preoperative computed tomography with arterial phase undergoing partial PD or TP between 2014 and 2017 were identified from a prospective database. CAS was assessed based on computed tomography and graded according to its severity: no stenosis (<30%), grade A (30%-<50%), grade B (50%-≤80%), and grade C (>80%). Postoperative complications were assessed and uni- and multivariable risk analyses were performed. RESULTS Of 989 patients, 273 (27.5%) had CAS: 177 (17.9%) with grade A, 83 (8.4%) with grade B, and 13 (1.3%) with grade C. Postoperative morbidity and 90-day mortality occurred in 278 (28.1%) patients and 41 (4.1%) patients, respectively. CAS was associated with clinically relevant pancreatic fistula ( P =0.019), liver perfusion failure ( P =0.003), gastric ischemia ( P =0.001), clinically relevant biliary leakage ( P =0.006), and intensive care unit ( P =0.016) and hospital stay ( P =0.001). Multivariable analyses confirmed grade B and C CAS as independent risk factors for liver perfusion failure; in addition, grade C CAS was an independent risk factor for clinically relevant pancreatic fistula and gastric complications. CONCLUSIONS CAS is common in patients undergoing PD. Higher grade of CAS is associated with an increased risk for clinically relevant complications, including liver perfusion failure and postoperative pancreatic fistula. Precise radiological assessment may help to identify CAS. Future studies should investigate measures to mitigate CAS-associated risks.

Abstract
BACKGROUND The incidence of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) is high. We sought to develop a POPF prediction model based on a decision tree (DT) and random forest (RF) algorithm after PD and to explore its clinical value. METHODS The case data of 257 patients who underwent PD in a tertiary general hospital from 2013 to 2021 were retrospectively collected in China. The RF model was used to select features by ranking the importance of variables, and both algorithms were used to build the prediction model after automatic adjustment of parameters by setting the respective hyperparameter intervals and resampling as a 10-fold cross-validation method, etc. The prediction model's performance was assessed by the receiver operating characteristic curve (ROC) and the area under curve (AUC). RESULTS Postoperative pancreatic fistula occurred in 56 cases (56/257, 21.8%). The DT model had an AUC of .743 and an accuracy of .840, while the RF model had an AUC of .977 and an accuracy of .883. The DT plot visualized the process of inferring the risk of pancreatic fistula from the DT model on independent individuals. The top 10 important variables were selected for ranking in the RF variable importance ranking. CONCLUSION This study successfully developed a DT and RF algorithm for the POPF prediction model, which can be used as a reference for clinical health care professionals to optimize treatment strategies to reduce the incidence of POPF.

Abstract
Background and Objectives: Postoperative pancreatic fistula (POPF) is one of the most challenging complications after pancreatic resections, associated with prolonged hospital stay and high mortality. Early identification of pancreatic fistula is necessary for the treatment to be effective. Several prognostic factors have been identified, although it is unclear which one is the most crucial. Some studies show that post-pancreatectomy hypophosphatemia may be associated with the development of POPF. The aim of this systematic review was to determine whether postoperative hypophosphatemia can be used as a prognostic factor for postoperative pancreatic fistula. Materials and Methods: The systematic literature review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations (PRISMA) and was registered in the International Prospective Register of Systematic Reviews (PROSPERO). The PubMed, ScienceDirect, and Web of Science databases were systematically searched up to the 31st of January 2022 for studies analyzing postoperative hypophosphatemia as a prognostic factor for POPF. Data including study characteristics, patient characteristics, operation type, definitions of postoperative hypophosphatemia and postoperative pancreatic fistula were extracted. Results: Initially, 149 articles were retrieved. After screening and final assessment, 3 retrospective studies with 2893 patients were included in this review. An association between postoperative hypophosphatemia and POPF was found in all included studies. Patients undergoing distal pancreatectomy were more likely to develop severe hypophosphatemia compared to patients undergoing proximal pancreatectomy. Serum phosphate levels on postoperative day 4 (POD 4) and postoperative day 5 (POD 5) remained significantly lower in patients who developed leak-related complications showing a slower recovery of hypophosphatemia from postoperative day 3 (POD 3) through postoperative day 7 (POD 7). Moreover, body mass index (BMI) higher than 30 kg/m2, soft pancreatic tissue, abnormal white blood cell count on postoperative day 3 (POD 3), and shorter surgery time were associated with leak-related complications (LRC) and lower phosphate levels. Conclusions: Early postoperative hypophosphatemia might be used as a prognostic biomarker for early identification of postoperative pancreatic fistula. However, more studies are needed to better identify significant cut-off levels of postoperative hypophosphatemia and development of hypophosphatemia in the postoperative period.

Abstract
INTRODUCTION Pre-clinical studies suggest that thermal ablation of the main pancreatic duct (TAMPD) is more recommendable than glue for reducing postoperative pancreatic fistula (POPF). Our aims were (1) to analyze the changes in the pancreas of patients after TAMPD and (2) to correlate the clinical findings with those obtained from a study on an animal model. MATERIALS AND METHODS A retrospective early feasibility study of a marketed device for a novel clinical application was carried out on a small number of subjects (n = 8) in whom TAMPD was conducted to manage the pancreatic stump after a pancreatectoduodenectomy (PD). Morphological changes in the remaining pancreas were assessed by computed tomography for 365 days after TAMPD. RESULTS All the patients showed either Grade A or B POPF, which generally resolved within the first 30 days. The duct's maximum diameter significantly increased after TAMPD from 1.5 ± 0.8 mm to 8.6 ± 2.9 mm after 7 days (p = .025) and was then reduced to 2.6 ± 0.8 mm after 365 days PO (p < .0001). The animal model suggests that TAMPD induces dilation of the duct lumen by enzymatic digestion of ablated tissue after a few days and complete exocrine atrophy after a few weeks. CONCLUSIONS TAMPD leads to long-term exocrine pancreatic atrophy by completely occluding the duct. However, the ductal dilatation that occurred soon after TAMPD could even favor POPF, which suggests that TAMPD should be conducted several weeks before PD, ideally by digestive endoscopy.

Abstract
Portal annular pancreas is a little-known anatomical variant of annular pancreas. In these patients, pancreatic parenchyma encircles the portal vein annularly. This anomaly is associated with high risk of postoperative pancreatic fistula in pancreatic surgery. Considering small incidence of anomaly and characteristics of surgery, we describe laparoscopic distal pancreatectomy with preservation of spleen and splenic vessels in a patient with solid pseudopapillary tumor combined with portal annular pancreas. A 33-year-old woman underwent laparoscopic surgery for cystic-solid pancreatic tumor. Spleen-sparing distal pancreatectomy was performed. Portal annular pancreas was visualized intraoperatively and confirmed retrospectively after analysis of MR data. Ventral and dorsal parts of portal annular pancreas were transected using stapler device. Pancreatic fistula developed in postoperative period. The patient was discharged after 6 days with a drainage tube. Surgeons need to be aware of portal annular pancreas. This anomaly increases the risk of postoperative fistula. Transection of ventral and dorsal parts of annular pancreas using stapler device is the most acceptable option to reduce the risk of postoperative fistula.

Abstract
Postoperative pancreatic fistula (POPF) following pancreatoduodenectomy (PD) is a potentially lethal complication, and it is clinically important to determine its risk preoperatively. Although C-reactive protein-to-albumin ratio (CAR) is reported to be a prognostic marker for postoperative complications in several cancers, no evidence is currently available regarding the association between preoperative CAR and POPF following PD for periampullary tumors. This study examined whether preoperative CAR could predict POPF following PD. Clinical data were retrospectively retrieved from Ehime University Hospital. The optimal cut-off value for CAR was determined using receiver operating characteristic (ROC) curve analysis. This study enrolled 203 consecutive patients undergoing PD for periampullary tumors. The CAR value was significantly higher in the POPF group than in the non-POPF group (p < 0.001). According to the ROC curve analysis, the optimal cut-off value for CAR was 0.09. Patients with CAR ≥ 0.09 had higher incidence rates of POPF than their counterparts. CAR ≥ 0.09 was a risk factor for POPF in the multivariate logistic regression analysis (odds ratio 34.5, 95% confidence interval 11.75-101.38, p < 0.001). This is the first report demonstrating an association between CAR and POPF following PD. Preoperative CAR is an independent predictive marker for POPF following PD.

Abstract
Postoperative pancreatic fistula (POPF) are major postoperative complications (POCs) following distal pancreatectomy (DP). Notably, POPF may worsen the prognosis of patients with pancreatic cancer. Previously reported risks for POCs include body mass index, pancreatic texture, and albumin levels. Moreover, the C-reactive protein-to-albumin ratio (CAR) is a valuable parameter for prognostication. On the other hand, POCs sometimes lead to a worse prognosis in several cancer types. Thus, we assumed that CAR could be a risk factor for POPFs. This study investigated whether CAR can predict POPF risk in patients with pancreatic cancer following DP. This retrospective study included 72 patients who underwent DP for pancreatic cancer at Ehime University between January 2009 and August 2022. All patients underwent preoperative CAR screening. Risk factors for POPF were analyzed. POPF were observed in 17 of 72 (23.6%) patients. POPF were significantly associated with a higher CAR (p = 0.001). The receiver operating characteristic curve analysis determined the cutoff value for CAR to be 0.05 (sensitivity: 76.5%, specificity: 88.9%, likelihood ratio: 6.88), indicating an increased POPF risk. Univariate and multivariate analysis revealed that CAR ≥ 0.05 was a statistically independent factor for POPF (p < 0.001, p = 0.013). Therefore, CAR has the potential to predict POPF following DP.

Abstract
BACKGROUND/PURPOSE Postoperative pancreatic fistula (POPF) is a serious complication of pancreaticoduodenectomy and current predictors of POPF are inadequate. We developed a new fistula score to more accurately predict POPF. METHODS We retrospectively reviewed 169 patients who underwent pancreaticoduodenectomy between January 2010 and August 2021 at our institution and examined patients' risk factors according to the occurrence of grade B/C POPF. Muscle and fat were assessed on preoperative computed tomography images and cutoff values were determined by receiver operating characteristic curve analysis. RESULTS Grade B/C POPF occurred in 38 (22.5%) patients. Multivariate analysis of patients' risk factors revealed that sarcopenic obesity (odds ratio [OR] 2.94; p = .033), L3 subcutaneous fat area (SFA) ≥ 98.0 cm2 (OR 2.69; p = .049), and soft pancreatic texture (OR 27.5; p = .002) were independent risk factors of grade B/C POPF occurrence. In addition, a new fistula risk score based on these factors revealed that 63.6% of patients with high scores developed grade B/C POPF, while those with negligible or low scores did not. CONCLUSIONS A new fistula risk scoring system based on sarcopenic obesity, SFA, and pancreatic texture may accurately predict POFP.

Abstract
Delayed gastric emptying (DGE) ranks as one of the most frequent complications in pancreatic surgery. It leads to increased costs for healthcare systems, lengthened hospital stays and reduced quality of life. Data about DGE after distal pancreatectomy (DP) are scarce. The StuDoQ|Pancreas registry of the German Society of General and Visceral Surgery provided data of patients who underwent distal pancreatectomy from 1 January 2014 to 31 December 2018. The retrospective evaluation included comprehensive data: 1688 patients were enrolled; DGE occurred 160 times (9.5%); grade “A” was reported for 98 (61.3%), grade “B” for 41 (25.6%) and grade “C” for 21 (13.1%) patients. In univariate analysis pancreatic fistulas were associated with higher frequencies of intraabdominal abscesses (9.1% vs. 2%, p > 0.001), postpancreatectomy haemorrhage (8.1% vs. 3.7%, >0.001) and DGE (14.5% vs. 6%, p < 0.001). According to multivariate analysis, “abscesses with invasive therapy” (p < 0.001), “other surgical complications” (p < 0.001), prolonged “stays in ICU” (p < 0.001), lengthened duration of surgery (p < 0.001) and conventional surgery (p = 0.007) were identified as independent risk factors for DGE. Perioperative and postoperative factors were identified as risk factors for DGE. Following research should examine this highly relevant topic in a prospective, register-based manner. As there is no causal therapy for DGE, its avoidance is of major importance.

Abstract
INTRODUCTION Pancreatic resections are an important field of surgery worldwide to treat a variety of benign and malignant diseases. Postoperative pancreatic fistula (POPF) remains a frequent and critical complication after partial pancreatectomy and affects up to 50% of patients. POPF increases mortality, prolongs the postoperative hospital stay and is associated with a significant economic burden. Despite various scientific approaches and clinical strategies, it has not yet been possible to develop an effective preventive tool. The SmartPAN indicator is the first surgery-ready medical device for direct visualisation of pancreatic leakage already during the operation. Applied to the surface of pancreatic tissue, it detects sites of biochemical leak via colour reaction, thereby guiding effective closure and potentially mitigating POPF development. METHODS AND ANALYSIS The ViP trial is a prospective single-arm, single-centre first in human study to collect data on usability and confirm safety of SmartPAN. A total of 35 patients with planned partial pancreatectomy will be included in the trial with a follow-up of 30 days after the index surgery. Usability endpoints such as adherence to protocol and evaluation by the operating surgeon as well as safety parameters including major intraoperative and postoperative complications, especially POPF development, will be analysed. ETHICS AND DISSEMINATION Following the IDEAL-D (Idea, Development, Exploration, Assessment, and Long term study of Device development and surgical innovation) framework of medical device development preclinical in vitro, porcine in vivo, and human ex vivo studies have proven feasibility, efficacy and safety of SmartPAN. After market approval, the ViP trial is the IDEAL Stage I trial to investigate SmartPAN in a clinical setting. The study has been approved by the local ethics committee as the device is used exclusively within its intended purpose. Results will be published in a peer-reviewed journal. The study will provide a basis for a future randomised controlled interventional trial to confirm clinical efficacy of SmartPAN.

Abstract
Postoperative pancreatic fistula (POPF) is one of the most critical complications after pancreatic surgery. The relationship between sarcopenia and outcomes following this type of surgery is debated. The aim of this review was to assess the impact of sarcopenia on the risk of POPF. A literature search was performed using the PubMed database and the reference lists of relevant articles to identify papers about the impact of sarcopenia on POPF in pancreatic surgery. Twenty-one studies published between 2016 and 2021 with a total of 4068 patients were included. Some studies observed a significant difference in the incidence of POPF between the sarcopenic and non-sarcopenic patients undergoing pancreatoduodenectomy. Interestingly, there was a trend of a lower POPF rate in sarcopenic patients than in non-sarcopenic patients. Only one study included patients undergoing distal pancreatectomy specifically. The role of sarcopenia in surgical outcomes is still unclear. A combination of objective CT measurements could be used to predict POPF. It could be assessed by routine preoperative staging CT and could improve preoperative risk stratification in patients undergoing pancreatic surgery.

Abstract
BACKGROUND/AIM Postoperative pancreatic fistula (POPF) is the most serious complication of distal pancreatectomy (DP). When POPF occurs and becomes severe, it causes secondary complications and leads to a longer treatment period. This study aimed to identify early predictive factors of POPF after DP for pancreatic cancer (PC). PATIENTS AND METHODS This retrospective, single-institution study comprised of 55 patients with PC who underwent DP between 2010 and 2021 at the Gifu University Hospital. We statistically analyzed pre-, intra-, and post-operative factors to identify early predictive factors for POPF. RESULTS According to the definition and grading of the International Study Group of Pancreatic Fistula (ISGPF), 12 (21.8%) of 55 patients had POPF grades B and C. In the univariate analysis, POPF was significantly associated with the pancreas-to-muscle signal intensity ratio on T 1 -weighted magnetic resonance imaging (SIR on T 1 -w MRI), the drainage fluid amylase (D-Amy) levels on postoperative day 3 (POD3), C-reactive protein (CRP) on POD3, and heart rate on POD3. In multivariate analysis, pancreas-to-muscle SIR on T 1 -w MRI [>1.37; odds ratio (OR)=17.08; 95% confidence interval (CI)=1.64-598.16; p=0.02], D-Amy levels on POD3 (>1,200 U/l; OR=20.00; 95% CI=1.73-563.83; p=0.02) and heart rate on POD3 (>100 bpm; OR=15.33; 95% CI=1.53-258.45; p=0.02) were identified as independent early predictive factors. CONCLUSION Preoperative pancreas-to-muscle SIR on T 1 -w MRI and postoperative D-Amy levels and heart rate significantly correlated with POPF after DP for PC. Postoperative management based on these predictive factors may improve the postoperative course.

Abstract
BACKGROUND Postoperative pancreatic fistula is one of the most critical complications following pancreatic surgery. This study aimed to evaluate the utility of selective prophylactic octreotide for patients at high risk of developing postoperative pancreatic fistula. METHODS From June 2019 to July 2020, 263 patients underwent pancreatoduodenectomy with pancreatojejunostomy at Samsung Medical Center. The individual fistula risk scores were calculated using a previously developed nomogram. The clinicopathological data of the patients were retrospectively reviewed. RESULTS There were 81 patients in the low-risk group and 182 patients in the high-risk group. No statistically significant differences were found in the rates of clinically relevant postoperative pancreatic fistula between octreotide group and the control group in all patients (15.0% vs 14.7%, P = .963) and in the high-risk group (16.1% vs 23.6%, P = .206). In risk factor analysis, postoperative octreotide was not an independent risk factor for clinically relevant pancreatic fistula in all patients and the high-risk group. Drain fluid amylase levels on the first postoperative day were significantly associated with clinically relevant postoperative pancreatic fistula, regardless of the individual risk. CONCLUSIONS The selective use of octreotide, even in high-risk patients, showed no protective effect against pancreatic fistula. Therefore, the routine use of postoperative octreotide is not recommended.

Abstract
Introduction
Choledochal cyst is a premalignant condition and surgical excision with biliary enteric anastomosis is the standard of care. Surgical treatment in adults may be difficult due to associated biliary pathology and high incidence of postoperative complications is reported. Postoperative pancreatic fistula (POPF) is a rare early complication following choledochal cyst excision.
Material and Methods
A 23-year-old male patient was operated for a Todani type IV-A choledochal cyst with anomalous pancreaticobiliary junction. Cyst excision with hepaticojejunostomy was performed. Distal stump closure was technically challenging due to extreme thickening of the cyst wall with neovascularization. On postoperative day 2, patient developed tachycardia and progressive tachypnea with 200 mL of pancreatic fluid in the drain. Endoscopic pancreatic stenting was attempted but was technically not possible. At reexploration, leak from oversewn distal cyst stump was identified and the suture line was reinforced. After the second surgery the patient was hemodynamically stable but continued to have a low output pancreatic fistula for few days which was managed conservatively successfully. We conducted a review of English literature with an aim to identify the risk factors and predictors of pancreatic fistula following cyst excision. An electronic search was performed in Medline and Google Scholar during September 2020 and available literature since January 2000 were reviewed. The keywords used were “pancreatic fistula” and “choledochal cyst.”
Results
Preoperative cholangiography (magnetic resonance cholangiopancreotography/endoscopic retrograde cholangiopancreatography) is essential to know the extent of cyst and delineate biliary pancreatic junction. Literature review including our case revealed that Todani type I-c, type IV, and forme fruste type of choledochal cyst are at high risk of pancreatic injury and POPF. Recurrent cholangitis makes excision technically more challenging and complete removal is not always possible.
Conclusion
Postoperative pancreatic fistula can be anticipated in select group of patients with high-risk preoperative findings. Chronic inflammation due to recurrent cholangitis promotes scarring and neovascularization which adds to surgical complexity. Operative technique in these high-risk patients needs further refinement.

Abstract
Background: Postoperative pancreatic fistula (POPF) is a major cause of morbidity after pancreaticoduodenectomy. There is no consensus on the best technique to protect the pancreato-enteric anastomosis and reduce the rate of POPF. This study investigated the feasibility and efficiency of external suction drainage of the pancreatic duct to improve the healing of pancreaticogastrostomy. Methods: Between July 2019 and June 2021, 21 consecutive patients undergoing elective pancreaticoduodenectomy were included. In all patients we performed a pancreaticogastrostomy and inserted a negative pressure drainage into the pancreatic duct. The length and diameter of the pancreatic duct were measured and the texture of the pancreas was evaluated. The daily secretion volume and the lipase value via pancreatic duct drainage were documented. The occurrence of POPF was evaluated. Results: None of the patients had drainage-related complications. In 4 patients we registered a dislocation of the drainage from the pancreas duct into the stomach. 17/21 Patients showed no signs of POPF. A biochemical leak was measured in one patient. Furthermore, 2 patients had a POPF grade B. In one patient, POPF grade C required reoperation and resection of the remnant pancreas. All 4 cases of POPF met the risk criteria soft pancreas, high volume and high lipase value in the duct drainage. Conclusion: The insertion of the pancreatic duct drainage was feasible and caused no drainage-related morbidity. POPF-rate was moderate in the risk population of soft pancreas and small duct.

Abstract
Simple Summary The real influence of postoperative pancreatic fistula (POPF) on long-term survival after pancreatic cancer resection is unclear. The purpose of the present study was therefore to conduct a systematic review and meta-analysis of the impact of POPF on the disease-free and overall survival of patients with pancreatic cancer. Our results highlighted that clinically relevant POPF after surgery for PDAC seems to be significantly associated with shorter DFS and OS. Confirmation, with future studies, of a negative impact of POPF on survival may encourage the widespread use of risk-stratification tools for assessing fistula, centralization of patients, and probably a closer oncological follow-up. Abstract Background: The impact of postoperative pancreatic fistula (POPF) on survival after resection for pancreatic ductal adenocarcinoma (PDAC) remains unclear. Methods: The MEDLINE, Scopus, Embase, Web of Science, and Cochrane Library databases were searched for studies reporting on survival in patients with and without POPF. A meta-analysis was performed to investigate the impact of POPF on disease-free survival (DFS) and overall survival (OS). Results: Sixteen retrospective cohort studies concerning a total of 5019 patients with an overall clinically relevant POPF (CR-POPF) rate of 12.63% (n = 634 patients) were considered. Five of eleven studies including DFS data reported higher recurrence rates in patients with POPF, and one study showed a higher recurrence rate in the peritoneal cavity. Six of sixteen studies reported worse OS rates in patients with POPF. Sufficient data for a meta-analysis were available in 11 studies for DFS, and in 16 studies for OS. The meta-analysis identified a shorter DFS in patients with CR-POPF (HR 1.59, p = 0.0025), and a worse OS in patients with POPF, CR-POPF (HR 1.15, p = 0.0043), grade-C POPF (HR 2.21, p = 0.0007), or CR-POPF after neoadjuvant therapy. Conclusions: CR-POPF after resection for PDAC is significantly associated with worse overall and disease-free survival.

Abstract
Numerous strategies for perioperative nutrition therapy for patients undergoing pancreaticoduodenectomy (PD) have been proposed. This systematic review aimed to summarize the current relevant published randomized controlled trials (RCTs) evaluating different nutritional interventions via a traditional network meta-analysis (NMA) and component network meta-analysis (cNMA). EMBASE, MEDLINE, the Cochrane Library, and ClinicalTrials.gov were searched to identify the RCTs. The evaluated nutritional interventions comprised standard postoperative enteral nutrition by feeding tube (Postop-SEN), preoperative enteral feeding (Preop-EN), postoperative immunonutrients (Postop-IM), preoperative oral immunonutrient supplement (Preop-IM), and postoperative total parenteral nutrition (TPN). The primary outcomes were general, infectious, and noninfectious complications; postoperative pancreatic fistula (POPF); and delayed gastric emptying (DGE). The secondary outcomes were mortality and length of hospital stay (LOS). The NMA and cNMA were conducted with a frequentist approach. The results are presented as odds ratios (ORs) and 95% confidence intervals (CIs). Two primary outcomes, infectious complications and POPF, were positively influenced by nutritional interventions. Preop-EN plus Postop-SEN (OR 0.11; 95% CI 0.02~0.72), Preop-IM (OR 0.22; 95% CI 0.08~0.62), and Preop-IM plus Postop-IM (OR 0.11; 95% CI 0.03~0.37) were all demonstrated to be associated with a decrease in infectious complications. Postop-TPN (OR 0.37; 95% CI 0.19~0.71) and Preop-IM plus Postop-IM (OR 0.21; 95% CI 0.06~0.77) were clinically beneficial for the prevention of POPF. While enteral feeding and TPN may decrease infectious complications and POPF, respectively, Preop-IM plus Postop-IM may provide the best clinical benefit for patients undergoing PD, as this approach decreases the incidence of both the aforementioned adverse effects.

Abstract
BACKGROUND/AIM An update on the incidence, risk factors, clinical sequalae, and management of postoperative pancreatic fistula (POPF) following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). PATIENTS AND METHODS Retrospective analysis of prospectively collected data from the St George CRS/HIPEC database. RESULTS Sixty-five (5.7%) out of 1,141 patients developed a POPF. Patients with POPFs were older, had a higher peritoneal cancer index, longer operation time, and required more units of blood intraoperatively. Splenectomy and distal pancreatectomy were significant risk factors for developing POPFs. While there was no effect on overall long-term survival in POPF patients, they did suffer higher rates of Clavien-Dindo grade 3/4 complications, in-hospital deaths, and longer hospital length of stay. Of the 65 POPF patients, 23 were taken back to theatre, 48 required radiological drains and 7 underwent endoscopic retrograde cholangiopancreatography. CONCLUSION There are multiple risk factors for developing POPFs that are non-modifiable. While POPFs are associated with increased postoperative morbidity, long-term survival does not appear to be affected.

Abstract
Introduction Although new techniques and devices have been introduced, the incidence of postoperative pancreatic fistula (POPF) after distal pancreatectomy remains high. To reduce the risk of POPF, we developed an innovative ligation band and conducted this pilot study to assess the possibility of reducing the incidence of POPF and pancreatic necrosis after distal pancreatectomy. Methods Distal pancreatectomy was performed in three pigs. In two animals, ligation of the pancreas was performed while maintaining arterial blood flow to the stump, and in one animal, the arterial blood flow was occluded. After ligation, the pancreas was sharply divided. Animals were sacrificed seven days later, and the remnant pancreas was assessed histologically. POPF was defined as amylase in ascites > 3x the preoperative serum amylase level. The following equation was used to quantify the extent of necrotic tissue: necrotic tissue residual rate = necrotic tissue area/ cross-sectional area. Results All animals survived, and no POPF developed. For two animals in which arterial blood flow to the stump was maintained, necrotic tissue residual rates at the ligation line were 24% and 31%. At the pancreatic stump, necrotic tissue residual rates were 37% and 50%. In the animal in which arterial blood flow to the stump was occluded, the necrotic tissue residual rate at the ligation line was 83% and that at the pancreatic stump was 78%, both higher than that in animals in which arterial blood flow was maintained. In all animals, there was no injury to pancreatic tissue at the ligation line. Conclusion The pancreas ligation band can potentially prevent POPF after distal pancreatectomy by atraumatic ligation, and the band ligates the pancreatic stump while maintaining arterial blood flow and limiting pancreatic necrosis.

Abstract
Specific complications is an «Achilles heel» of pancreaticoduodenectomy. Postoperative pancreatic fistula (POPF) is the most common specific complication. POPF prediction is an actual problem in pancreatic surgery. Analysis of statistically significant scoring systems to predict POPF is a modern trend in perioperative planning. Several prognostic scales (FRS, a-FRS, ua-FRS, Modified Fistula Risk Score) are recommended for clinical practice.

Abstract
Background Pancreaticoduodenectomy and distal pancreatectomy are radical procedures for pancreatic lesions with high postoperative morbidity and mortality even in experienced hands. Central pancreatectomy is an alternative less radical procedure for centrally located pancreatic lesions that are benign or have a low malignant potential. It involves removing the central portion of the pancreas and has the advantage of preserving the pancreatic parenchyma, thereby decreasing the postoperative endocrine and exocrine insufficiencies. Methods We conducted a prospective study of six cases of central pancreatectomy in the Department of Surgical Gastroenterology and Liver Transplant, Government Stanley Medical College, India, between the years 2015 and 2019. All patients with lesions in the neck and proximal body of the pancreas were clinically and radiologically evaluated, and those with benign or borderline malignant lesions underwent central pancreatectomy by a standardized technique. Results The mean age of the patients was 27.8 years (range: 14 years - 37 years). Most of the patients were females (66.6%). The most common presenting symptom was abdominal pain, and the most common diagnosis was solid pseudopapillary neoplasm (83.3%). The mean diameter of the lesion was 6.1 cm. All patients underwent pancreaticojejunostomy of the distal stump. The median operative time and the blood loss were 310 minutes and 85 ml, respectively. Two patients developed biochemical postoperative pancreatic fistula, and in the long-term follow-up, none of them developed endocrine or exocrine insufficiency. Conclusion Central pancreatectomy is a safe and effective alternative for benign and low-grade lesions in the neck and body of the pancreas in which the head of the pancreas and a significant portion of the distal body and tail of the pancreas is uninvolved. Standardization of this pancreas-preserving procedure will result in better outcomes.

Abstract
The latest guidelines from the Enhanced Recovery After Surgery (ERAS®) Society stated that early drain removal after pancreatoduodenectomy (PD) is beneficial in decreasing complications including postoperative pancreatic fistulas (POPFs). This study aimed to ascertain the actual benefits of early drain removal after PD. The data of 450 patients who underwent PD between 2018 and 2020 were retrospectively reviewed. The surgical outcomes were compared between patients whose drains were removed within 3 postoperative days (early removal group) and after 5 days (late removal group). Logistic regression analysis was performed to identify the risk factors for clinically relevant POPFs (CR-POPFs). Among the patients with drain fluid amylase < 5000 IU on the first postoperative day, the early removal group had fewer complications and shorter hospital stays than the late removal group (30.9% vs. 54.5%, p < 0.001; 9.8 vs. 12.5 days, p = 0.030, respectively). The incidences of specific complications including CR-POPFs were comparable between the two groups. Risk factor analysis showed that early drain removal did not increase CR-POPFs (p = 0.163). Although early drain removal has not been identified as apparently beneficial, this study showed that it may contribute to an early return to normal life without increasing complications.

Abstract
Postoperative pancreatic fistula (POPF), the major driver of morbidity and mortality following pancreatectomy, is caused by an abnormal communication between the pancreatic ductal epithelium and another epithelial surface containing pancreas-derived, enzyme-rich fluid. There is a strong correlation between the amylase content in surgically-placed drains early in the postoperative course and the development of POPF. A simple and cheap method to determine the amylase content from the drain effluent has been eagerly advocated. Here, we developed an amylase optical biosensor, based on a surface plasmon resonance (SPR) plastic optical fiber (POF), metallized with a 60 nm layer of gold and interrogated with white light. The sensor was made specific by coupling it with an anti-amylase antibody. Each surface derivatization step was optimized and studied by XPS, contact angle, and fluorescence. The POF-biosensor was tested for its response to amylase in diluted drain effluents. The volume of sample required was 50 µL and the measurement time was 8 min. The POF-biosensor showed selectivity for amylase, a calibration curve log-linear in the range of 0.8-25.8 U/L and a limit of detection (LOD) of ~0.5 U/L. In preliminary tests, the POF-biosensor allowed for the measurement of the amylase content of diluted surgically-placed drain effluents with an accuracy of >92% with respect to the gold standard. The POF-biosensor allows for reliable measurement and could be implemented to allow for a rapid bedside assessment of amylase value in drains following pancreatectomy.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) can be life-threatening, and gadoxetic acid-enhanced MRI is routinely performed in patients undergoing pancreatic surgery. However, previous reports have not investigated if gadoxetic acid-enhanced MRI can be used to predict POPF risk. OBJECTIVE This study aims to explore if gadoxetic acid-enhanced MRI can predict pancreatic fibrosis and the need for POPF treatment before surgery. METHOD We retrospectively analyzed gadoxetic acid-enhanced MR images from 142 patients who underwent pancreatic surgery between January 1, 2011, and April 30, 2018. Pre-dynamic signal intensity (SI) and values for portal, transitional, and hepatobiliary phase standardized based on pre-dynamic study values were analyzed. The diameter of the main pancreatic duct (DMPD) was measured, and the degree of pancreatic fibrosis was classified as F0-F3. We defined POPF higher than grade B as significant. RESULTS Odds ratios for combinations that led to any degree of fibrosis higher than grade B were defined as significant risk factors. The highest odds ratio was obtained for F0 vs. F1-F3 (p = 0.038). DMPD (p < 0.001), pre-SI (p = 0.008), portal-SI/pre-SI (p < 0.001), transitional-SI/pre-SI (p < 0.001), and hepatobiliary-SI/pre-SI (p = 0.012) were significantly correlated with the presence of fibrosis. The presence of fibrosis was best detected by DMPD (AUC = 0.777). Individual specificity values of transitional-SI/pre-SI and DMPD were 95.5% and 86.6%, respectively, and their combined specificity was 97.7%. CONCLUSION The absence of pancreatic fibrosis is a risk factor for developing POPF higher than grade B. DMPD was the most useful diagnostic indicator of the presence of fibrosis among our analysis, and its specificity increased when combined with transitional-SI/pre-SI.

Abstract
BACKGROUND The aim of the present study was to identify the predictors of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP). METHODS The records of 97 consecutive patients who underwent DP at Ehime University Hospital between June 2009 and August 2020 were retrospectively reviewed. Patient characteristics, preoperative blood biochemistry data, operative findings, and postoperative findings until postoperative day (POD) 3 were investigated as potential predictors of clinically relevant POPF (CR-POPF). The product of the drain fluid amylase (DFA) value (U/L) and the drainage amount (mL/day) was defined as DFA output (U/day). RESULTS Of 97 patients who underwent DP, 23 (23.7%) developed CR-POPF. On multivariate analyses, high C-reactive protein (CRP) levels on POD 3 (>14.0 mg/dL) and high DFA output on POD 3 (>34 U/day) were found to be independent predictors of CR-POPF (odds ratios, 7.580 and 4.751, respectively; 95% confidence intervals, 2.052-27.995 and 1.487-15.175, respectively). Furthermore, the CRP value was helpful for predicting delayed CR-POPF in patients without POPF on POD3, and DFA output was useful for predicting the development of CR-POPF in patients diagnosed with POPF on POD3. CONCLUSION Postoperative CRP values and DFA output may facilitate appropriate postoperative management after DP.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is the most common complication following distal pancreatectomy. This retrospective study investigated the effects of autologous fibrin sealant (Vivostat©) in reducing the incidence of POPF after distal pancreatectomy. METHODS A matched pairs analysis was performed to compare the incidence of clinically relevant POPF of 41 patients who underwent a distal pancreatectomy with application of autologous fibrin sealant (Vivostat©) with a historical control group. RESULTS Clinically relevant POPF were present in 11 patients in the study group (27%) and in 13 patients in the control group (32%, p = .639). No patient of the study group required emergency angiographic treatment for postoperative hemorrhage due to POPF, whereas three patients were identified in the control group (7%, p = .079). CONCLUSIONS POPF cannot be prevented under treatment with autologous fibrin sealant (Vivostat©). We observed the tendency of a lower rate of postoperative pancreatic hemorrhage due to POPF. However, prospective randomized controlled studies are required.

Abstract
BACKGROUND/AIM Drains are frequently placed at the time of distal pancreatectomy (DP) to evacuate pancreatic juice and intra-abdominal exudate and obtain information on abdominal cavity status. However, the timing of drain removal remains debatable. Meanwhile, prolonged drain placement might increase the risk of postoperative pancreatic fistula (POPF), with a prevalence of 5-40%. Therefore, we examined the effect of removing the drain within postoperative day (POD) 3 on the risk of POPF development. PATIENTS AND METHODS A total of 108 consecutive patients who underwent DP between April 2015 and March 2020 were examined and divided into two groups according to the day of drain removal; hence, for some patients, the drain was removed on POD 1 (POD 1 group) and for others on POD 3 (POD 3 group). Furthermore, risk factors, including drain fluid amylase (DFA) levels, for developing POPF were investigated. RESULTS The overall rate of clinically relevant POPF was 4.6% and did not significantly differ between the POD 1 and POD 3 groups [4.5% and 4.9%, respectively (p=0.924)]. DFA levels on POD 1 did not significantly differ between patients with and without POPF. On POD 3 and POD 5, C-reactive protein (CRP) levels were significantly higher in patients with POPF than in those without (p=0.03 and p<0.001, respectively). CONCLUSION Early drain removal regardless of DFA level may reduce the risk of developing POPF. CRP measured on POD 3 and POD 5 appeared to be a useful predictor of clinically relevant POPF.

Abstract
Early intra-abdominal infection (IAI) following pancreaticoduodenectomy (PD) is an initial event relating to morbidities caused by postoperative pancreatic fistula (POPF). The aims of this study were to determine factors associated with IAI, and to investigate its impact on postoperative outcome. Consecutive patients, 113 in total, who underwent PD at Fukushima Medical University Hospital between January 2012 and September 2017 were included in this retrospective study. IAI was defined by positive bacterial culture from intra-abdominal drainage fluid any time through postoperative day 3 (POD3). Logistic regression analysis was used to identify the relevant factors associated with IAI. The clinical impact of the POD3 infection indicators related to POPF were assessed by multivariate analysis. The incidence of IAI, POPF, and mortality were 36.1%, 36.1%, and 0%, respectively. Independent factors associated with IAI were preoperative biliary drainage (PBD) (OR = 2.91, CI = 1.16-7.33, p = 0.023) and soft pancreas (OR = 8.67, CI = 2.37-31.77, p = 0.001). Among infection markers on POD3, the significant factors for POPF were CRP (OR = 1.18, CI = 1.08-1.30, p < 0.001), IAI (OR = 7,37, CI = 2.53-21.5, p < 0.001), and drain amylase (OR = 1.00, CI = 1.00-1.01, p = 0.001). In conclusion, PBD, soft pancreas, and higher age were associated with IAI. IAI has a significantly negative impact on postoperative outcome.

Abstract
INTRODUCTION Pancreatic cancer is malignancy with poor prognosis for quality of life and overall survival. The incidence is variant, 7.7/100,000 in Europe, 7.6/100,000 in the USA, 2.2/100.000 in Africa. The only real benefit for cure is surgery, duodenopancreatectomy. The key points for this procedure are radicality, low morbidity and low mortality, the follow up and the expected overall survival. The benchmark of the procedure is the pancreaticojejunoanastomosis, with its main pitfall, postoperative pancreatic fistula B or C. Subsequently, the manner of creation of pancreaticojejunoanastomosis defines the safety, thus the postoperative morbidity and mortality. Finally, this issue remarkably depends on the surgeon and the surgical technique creating the anastomosis. We used 2 techniques with interrupted sutures, dunking anastomosis and duct-to-mucosa double layer technique. The objective of the study was to compare these 2 suturing techniques we applied, and the aim was to reveal the risk benefit rationale for dunking either duct to mucosa anastomosis. MATERIAL AND METHOD In our last series of 25 patients suffering pancreatic head carcinoma we performed a standard dodenopancreatectomy. After the preoperative diagnosis and staging with US, CICT, tumor markers, they underwent surgery. Invagination-dunking anastomosis was performed in 15, whereas, duct-to-mucosa, double layer anastomosis was performed in 10. In the first group with dunking anastomosis, we had 6 patients with soft pancreas and 8 with narrow main pancreatic duct, less than 3 mm. In the duct-to-mucosa group there were 5 patients with soft pancreas and 4 with narrow main pancreatic duct. All other stages of surgery were unified, so the only difference in the procedure remained on the pancreatojejunoanastomosis. The onset of the postoperative pancreatic fistula was estimated with revelation of 3 fold serum level of alfa amylases from the third postoperative day in the drain liquid. RESULTS In the duct to mucosa group there wasn't a clinically relevant postoperative pancreatic fistula, while in the dunking anastomosis group we had 4 postoperative pancreatic fistula B, 26 %. One of these 4 patients experienced intraabdominal collection - abscess, conservatively managed with lavation through the drain. Comparing the groups, there was no significant difference between the groups concerning the appearance of postoperative pancreatic fistula: p>0.05, p=0.125. From all 25 patients, in 21 patients biliary stent was installed preoperatively to resolve the preoperative jaundice. All 21 suffered preoperative and postoperative reflux cholangitis, extending the intra-hospital stay. CONCLUSION So far, there have been many trials referring to opposite results while comparing these 2 techniques in creation of the pancreticojejunoanastomosis. In our study, the duct to mucosa anastomosis prevailed as a technique, proving its risk benefit rationale. However, further large randomized clinical studies have to be conducted to clarify which of these procedures would be the prime objective in the choice of the surgeon while creating pancreatojejunoanastomosis.

Abstract
Aim To evaluate the efficacy of a novel hydrogel sheet in preventing postoperative pancreatic fistula (POPF). Background Postoperative pancreatic fistula is a life‐threatening complication. As no study has reported the use of hydrogel sheets in preventing POPF, their effectiveness for that purpose remains unclear. Methods A novel hydrogel sheet made of polyvinyl alcohol (PVA) was prepared by the freeze‐thaw method. The pancreatic ducts and surrounding pancreatic parenchyma of rats were transected to induce a pancreatic fistula. Next, the sheet was attached to the transection site. Ascitic fluid amylase and lipase concentrations were measured. Neoveil®, a nonwoven polyglycolic acid (PGA) felt, is already clinically used as an absorbable reinforcing material at pancreatic transection sites. Neoveil® was used for comparison, as was VIEWGEL®, which is marketed as a wound dressing. Results The hydrogel sheet remained in place 48 hours postoperatively. The ascitic amylase concentrations in the control, VIEWGEL®‐treated, Neoveil®‐treated, and hydrogel‐treated rats, respectively, were 4992.4 ± 5355.7, 1068.4 ± 269.1, 730.2 ± 425.2, and 303.1 ± 240.1 IU/L; the ascitic lipase concentrations were 2279.8 ± 3395.2, 169.5 ± 100.6, 90.4 ± 71.0, and 86.8 ± 59.8 IU/L. The ascitic amylase and lipase levels were significantly lower in the hydrogel group than in the other groups (P < .05). Conclusions This novel hydrogel sheet effectively prevents pancreatic fistulas and has promising clinical application potential.

Abstract
BACKGROUND The utilization of neoadjuvant therapy (NAT) before performing pancreaticoduodenectomy for malignancy has been well established as a protective factor for the prevention of postoperative pancreatic fistula (POPF). However, there is a paucity of published data evaluating the specific NAT regimen that is the most protective against POPF development. We evaluated the differences between neoadjuvant chemotherapy (CT) and chemoradiation therapy (CRT) with regard to the effect on POPF rates. METHODS The main and targeted pancreatectomy American College of Surgeons National Surgical Quality Improvement Program registries for 2014-2016 were retrospectively reviewed. A total of 10,665 pancreaticoduodenectomy cases were present. The primary outcome was POPF development. The factors that have previously been shown to be associated with or suspected to be associated with POPF were evaluated. The factors included NAT, sex, age, body mass index (BMI), diabetes, smoking, steroid therapy, preoperative weight loss, preoperative albumin level, perioperative blood transfusions, wound classification, American Society of Anesthesiologists classification, duct size (<3 mm, 3-6 mm, and >6 mm), gland texture (soft, intermediate, and hard), and anastomotic technique. The factors identified to be statistically significant were then used for propensity score matching to compare POPF development between the cases utilizing CT versus CRT. RESULTS A total of 10,117 cases met the inclusion criteria. The development of POPF was significantly associated, on multivariate analysis, with a lack of NAT, male sex, higher BMI, nondiabetic status, nonsmoker status, decreased weight loss, preoperative albumin level, decreased duct size, and soft gland texture. NAT, duct size, and gland texture had the strongest associations with the development of POPF (p < .0001). The overall 1765 cases (17.45%) received NAT and the POPF rate for cases with NAT was 10.20% versus 20.10% for cases without NAT (p < .0001). A total of 1031 cases underwent CT and 734 cases underwent CRT, respectively. A total of 708 paired cases were selected for analysis based on propensity score matching. The POPF rates were 11.20% versus 3.50% for CT and CRT, respectively (p < .0001). There was no difference in the frequencies of specific POPF grades. The decreased POPF rate with CRT correlated with firmer gland texture rates. CONCLUSIONS To our knowledge, this is the largest analysis of specific NAT regimens with regard to the development of POPF following pancreaticoduodenectomy. CRT provided the strongest protective effect. That protective effect is most likely due to increased fibrosis in the pancreatic parenchyma from radiation therapy. These findings provide additional support to consider CRT over CT alone in the treatment of pancreatic cancer when NAT will be utilized.

Abstract
BACKGROUND A randomized controlled trial of routine administration of pasireotide demonstrated decreased incidence of clinically significant postoperative pancreatic fistula (POPF). Recent studies have not replicated these results. A meta-analysis was performed to evaluate its efficacy in this setting. METHODS Prospective trials utilizing pasireotide prophylactically after pancreatectomy were reviewed. The primary outcome was clinically significant POPF. Secondary outcomes included length of stay (LOS), readmission rates, and mortality. Study heterogeneity was assessed. RESULTS Five studies totaling 1571 patients were identified. There was no difference in age, sex, or cancer rates. Pasireotide patients had smaller pancreatic ducts (P < .001) and softer glands (P = .04). For all pancreatectomies, there was no difference in POPF rates (odds ratio [OR] 0.84; 95% CI 0.60-1.16, P = .29). Patients undergoing distal pancreatectomy (OR 0.70; 95% CI 0.30-1.63, P = .41) had similar rates of POPF versus pancreaticoduodenectomy (PD) patients who experienced a lower incidence of POPF (OR 0.60; 95% CI 0.42-0.86, P = .006).Mortality rates and LOS were similar. Readmission rates were decreased with pasireotide (OR 0.61; 95% CI 0.44-0.85). CONCLUSIONS Routine administration of pasireotide did not decrease POPF rates for all pancreatectomies, but was associated with lower rates for PD, and decreased readmission rates. Further prospective, randomized studies are warranted.

Abstract
Although laparoscopic distal pancreatectomy (LDP) has become more popular, the postoperative complication rate remains high. We sought to identify the risk factors for post-LDP complications. We examined 1227 patients who underwent LDP between March 2005 and December 2015 at a single large-volume center. We used logistic regression for the analysis. The overall (13.2%) and major (3.3%) complication rates were determined. Postoperative pancreatic fistula was the most frequent complication, and 58 patients (4.7%) had clinically significant (grade B) pancreatic fistulas. No 90-day mortality was recorded. Long operative time (≥200 min), large estimated blood loss (≥320 mL), LDP performed by an inexperienced surgeon (<50 cases), and concomitant splenectomy were identified as risk factors for overall complications using a logistic regression model. For major complications, male sex (p = 0.020), long operative time (p = 0.005), and LDP performed by an inexperienced surgeon (p = 0.026) were significant predictive factors. Using logistic regression analysis, surgery-related factors, including long operative time and LDP performed by an inexperienced surgeon, were correlated with overall and major complications of LDP. As LDP is a technically challenging procedure, surgery-related variables emerged as the main risk factors for postoperative complications. Appropriate patient selection and sufficient surgeon experience may be essential to reduce the complications of LDP.
