A triple arm, randomized placebo-controlled trial. Ann Hepatobiliary Pancreat Surg 2024; 28:350-357. [PMID: 38679455 PMCID: PMC11341883 DOI: 10.14701/ahbps.24-021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 03/14/2024] [Accepted: 04/02/2024] [Indexed: 05/01/2024] Open
Abstract
Backgrounds/Aims This trial evaluated whether anti-inflammatory agents hydrocortisone (H) and indomethacin (I) could reduce major complications after pancreatoduodenectomy (PD). Methods Between June 2018 and June 2020, 105 patients undergoing PD with > 40% of acini on the intraoperative frozen section were randomized into three groups (35 patients per group): 1) intravenous H 100 mg 8 hourly, 2) rectal I suppository 100 mg 12 hourly, and 3) placebo (P) from postoperative day (POD) 0-2. Participants, investigators, and outcome assessors were blinded. The primary outcome was major complications (Clavien-Dindo grades 3-5). Secondary outcomes were overall complications (Clavien-Dindo grades 1-5), Clinically relevant postoperative pancreatic fistula (CR-POPF), delayed gastric emptying (DGE), postpancreatectomy hemorrhage (PPH), surgical site infections (SSI), length of stay, POD-3 serum amylase, readmission rate, and mortality. Results Major complications were comparable (8.6%, 5.7%, and 8.6% in groups H, I, and P, respectively). However, overall complications were significantly lower in group H than in group P (45.7% vs. 80.0%, p = 0.006). CR-POPF (14.3% vs. 25.7%, p = 0.371), PPH (8.6% vs. 14.3%, p = 0.710), DGE (8.6% vs. 22.9%, p = 0.188), and SSI (14.3% vs. 25.7%, p = 0.371) were comparable between groups H and P. Major complications and overall complications in group I were 5.7% and 60.0%, respectively, which were comparable to those in groups P and H. CR-POPF rates in groups H, I, and P were 14.3%, 17.1%, and 25.7%, respectively, which was comparable. Conclusions H and I did not decrease major complications in PD.

Abstract
OBJECTIVE To evaluate the effect of perioperative dexamethasone on postoperative complications after pancreaticoduodenectomy. BACKGROUND The glucocorticoid dexamethasone has been shown to improve postoperative outcomes in surgical patients, but its effects on postoperative complications after pancreaticoduodenectomy are unclear. METHODS This multicenter, double-blind, randomized controlled trial was conducted in four Chinese high-volume pancreatic centers. Adults undergoing elective pancreaticoduodenectomy were randomized to receive either 0.2 mg/kg dexamethasone or a saline placebo as an intravenous bolus within 5 minutes after anesthesia induction. The primary outcome was the Comprehensive Complication Index (CCI) score within 30 days after the operation, analyzed using the modified intention-to-treat principle. RESULTS Among 428 patients for eligibility, 300 participants were randomized and 265 were included in the modified intention-to-treat analyses. One hundred thirty-four patients received dexamethasone and 131 patients received a placebo. The mean (SD) CCI score was 14.0 (17.5) in the dexamethasone group and 17.9 (20.3) in the placebo group (mean difference: -3.8; 95% CI: -8.4 to 0.7; P = 0.100). The incidence of major complications (Clavien-Dindo grade ≥III; 12.7% vs 16.0%, risk ratio: 0.79; 95% CI: 0.44 to 1.43; P = 0.439) and postoperative pancreatic fistula (25.4% vs 31.3%, risk ratio: 0.81; 95% CI: 0.55 to 1.19; P = 0.286) were not significantly different between the two groups. In the stratum of participants with a main pancreatic duct ≤3 mm (n = 202), the CCI score was significantly lower in the dexamethasone group (mean difference: -6.4; 95% CI: -11.2 to -1.6; P = 0.009). CONCLUSIONS Perioperative dexamethasone did not significantly reduce postoperative complications within 30 days after pancreaticoduodenectomy.

Abstract
OBJECTIVE The aim of this study was to develop a novel machine learning model to predict clinically relevant postoperative pancreatic fistula (CR-POPF) following pancreaticoduodenectomy (PD). BACKGROUND Accurate prognostication of CR-POPF may allow for risk stratification and adaptive treatment strategies for potential PD candidates. However, antecedent models, such as the modified Fistula Risk Score (mFRS), are limited by poor discrimination and calibration. METHODS All records entailing PD within the 2014 to 2018 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) were identified. In addition, patients undergoing PD at our institution between 2013 and 2021 were queried from our local data repository. An eXtreme Gradient Boosting (XGBoost) model was developed to estimate the risk of CR-POPF using data from the ACS NSQIP and evaluated using institutional data. Model discrimination was estimated using the area under the receiver operating characteristic (AUROC) and area under the precision recall curve (AUPRC). RESULTS Overall, 12,281 and 445 patients undergoing PD were identified within the 2014 to 2018 ACS NSQIP and our institutional registry, respectively. Application of the XGBoost and mFRS scores to the internal validation dataset revealed that the former model had significantly greater AUROC (0.72 vs 0.68, P <0.001) and AUPRC (0.22 vs 0.18, P <0.001). Within the external validation dataset, the XGBoost model remained superior to the mFRS with an AUROC of 0.79 (95% CI: 0.74-0.84) versus 0.75 (95% CI: 0.70-0.80, P <0.001). In addition, AUPRC was higher for the XGBoost model, compared with the mFRS. CONCLUSION Our novel machine learning model consistently outperformed the previously validated mFRS within internal and external validation cohorts, thereby demonstrating its generalizability and utility for enhancing prediction of CR-POPF.

Abstract
OBJECTIVE Pharmacological prevention of postoperative pancreatic fistula (POPF) after pancreatectomy is open to debate. The present study compares clinically significant POPF rates in patients randomized between somatostatin versus octreotide as prophylactic treatment. METHODS Multicentric randomized controlled open study in patient's candidate for pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) comparing somatostatin continuous intravenous infusion for 7 days versus octreotid 100 μg, every 8 hours subcutaneous injection for 7 days, stratified by procedure (PD vs DP) and size of the main pancreatic duct (>4 mm) on grade B/C POPF rates at 90 days based on an intention-to-treat analysis. RESULTS Of 763 eligible patients, 651 were randomized: 327 in the octreotide arm and 324 in the somatostatin arm, with comparable the stratification criteria - type of surgery and main pancreatic duct dilatation. Most patients had PD (n=480; 73.8%), on soft/normal pancreas (n=367; 63.2%) with a nondilated main pancreatic duct (n=472; 72.5%), most often for pancreatic adenocarcinoma (n=311; 47.8%). Almost all patients had abdominal drainage (n=621; 96.1%) and 121 (19.5%) left the hospital with the drain in place (median length of stay=16 days). A total of 153 patients (23.5%) developed a grade B/C POPF with no difference between both groups: 24.1%: somatostatin arm and 22.9%: octreotide arm (χ 2 test, P =0.73, ITT analysis). Absence of statistically significant difference persisted after adjustment for stratification variables and in per-protocol analysis. CONCLUSION Continuous intravenous somatostatin is not statistically different from subcutaneous octreotide in the prevention of grade B/C POPF after pancreatectomy. FINDINGS In the PREFIPS Randomized Clinical Trial including 651 patients, a total of 153 patients (23.5%) developed a grade B/C POPF with no significant difference between both groups: 24.1%: somatostatin arm and 22.9%: octreotide arm (χ 2 test, P =0.73, ITT analysis). Absence of statistically significant difference persisted after adjustment for stratification variables and in per-protocol analysis.

Abstract
INTRODUCTION Grade-C postoperative pancreatic fistulas (POPFs) are dreaded complications following pancreaticoduodenectomy. The aim of this study was to quantify the incidence and risk factors associated with grade C POPF in a national database. METHODS The National Surgical Quality Improvement Program targeted user files were queried for patients who underwent elective pancreaticoduodenectomy (2014-2020). Outcomes were compared between clinically relevant (CR) grade B POPF and grade C POPF. RESULTS Twenty-six thousand five hundred fifty-two patients were included, of which 90.1% (n = 23,714) had No CR POPF, 8.7% (n = 2287) suffered grade B POPF, and 1.2% (n = 327) suffered grade C POPF. There was no change in the rate Grade-C fistula overtime (m = 0.06, P = 0.63), while the rate of Grade-B fistula significantly increased (m = +1.40, P < 0.01). Fistula Risk Scores were similar between grade B and C POPFs (high risk: 34.9% versus 31.2%, P = 0.21). Associated morbidity was increased with grade C POPF, including delayed gastric emptying, organ space infections, wound dehiscence, respiratory complications, renal complications, myocardial infarction, and bleeding. On multivariate logistic regression, diabetes mellitus (odds ratio: 1.41 95% confidence interval: 1.06-1.87, P = 0.02) was associated with grade C POPF. CONCLUSIONS This study represents the largest contemporary series evaluating grade C POPFs. Of those suffering CR POPF, the presence of diabetes mellitus was associated with grade C POPF. While modern management has led to grade C POPF in 1% of cases, they remain associated with alarmingly high morbidity and mortality, requiring further mitigation strategies to improve outcomes.

Preoperative ultrasound elastography for postoperative pancreatic fistula prediction after pancreatoduodenectomy: A prospective study. Surgery 2024; 175:491-497. [PMID: 38044240 DOI: 10.1016/j.surg.2023.10.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 07/07/2023] [Accepted: 10/24/2023] [Indexed: 12/05/2023]
Abstract
BACKGROUND Postoperative pancreatic fistulas are the most frequent major complications after pancreatoduodenectomy. The soft pancreatic texture is a critical, independent risk factor for postoperative pancreatic fistulas after pancreatoduodenectomy. The current gold standard for postoperative pancreatic fistula risk evaluation consists of the surgeon's intraoperative palpation of the pancreatic texture and, thus, lacks objectivity. In this prospective study, we used ultrasound-based shear-wave elastography, image data analysis, and a fistula risk score calculator to correlate the stiffness of pancreatic tissue with the occurrence of clinically relevant postoperative pancreatic fistulas. METHODS We included 100 patients with pancreatic pathologies (71% pancreatic ductal adenocarcinoma) and 100 healthy individuals who were preoperatively assessed via real-time tissue ultrasound-based shear-wave elastography on a Philips EPIQ 7 ultrasound device and had pancreatic parenchyma histologically evaluated with manually stained images. RESULTS We found a significant difference in the mean elasticity between the soft (1.22 m/s) and the hard pancreas group (2.10 m/s; P < .0001). The mean elasticity significantly correlated with the pancreatic fibrosis rate and the appearance of a postoperative pancreatic fistula after pancreatoduodenectomy. Low elasticity (≤1.2 m/s, mean) correlated with soft and high elasticity (>2.0 m/s, mean) with hard pancreatic parenchyma, as assessed by pathologic evaluation. Multivariate analysis revealed a mean elasticity of <1.3 m/s as a significant cut-off predictor for clinically relevant postoperative pancreatic fistulas (P = .003; Youden-Index = 0.6945). CONCLUSION Preoperative ultrasound-based shear-wave elastography is a feasible and objective clinical diagnostic modality in evaluating pancreatic tissue stiffness. A mean pancreatic elasticity of <1.3 m/s was a significant independent risk predictor of clinically relevant postoperative pancreatic fistulas after pancreatoduodenectomy.

BACKGROUND The aim of this study was to assess the incidence of bacterobilia at the time of a pancreaticoduodenectomy (PD) and the association of resistant bacteria in bile to surgical site infections (SSI). METHODS This was a retrospective cohort study including patients undergoing PD in a single center between May 2016 and October 2020. Data of preoperative biliary drainage (PBD), intraoperative biliary cultures (IBC) and postoperative complications were analysed to assess the risk factors for resistant bacteria in IBC and SSIs. RESULTS Of 361 patients included, 254 (70%) had undergone PBD. Second-generation cephalosporin resistant bacteria were found in IBC of 183 (64%) of all the patients. PBD was the only risk factor for second-generation cephalosporin resistance. The risk for second-generation cephalosporin resistance was more than 20-fold in patients with PBD [n = 170/254 (67%) (OR 22.58 (95% CI, 9.61-53.01), p < 0.001)] compared to patients who did not have PBD (n = 13/107 (12%)). Also, if the time between PBD and surgery was 2 months or more the second-generation cephalosporin resistance in IBC increased the risk for SSIs (OR 4.14 (95% CI, 1.18-14.51), p = 0.027). CONCLUSION The second-generation cephalosporin resistance in IBC is common in patients who have undergone PBD. Broad-spectrum antibiotics in prophylaxis may be beneficial for these patients.

Analysis of the Mechanical Characteristics of Human Pancreas through Indentation: Preliminary In Vitro Results on Surgical Samples. Biomedicines 2024; 12:91. [PMID: 38255197 PMCID: PMC10813168 DOI: 10.3390/biomedicines12010091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/15/2023] [Accepted: 12/27/2023] [Indexed: 01/24/2024] Open
Abstract
Pancreatic surgery is extremely challenging and demands an extended learning curve to be executed with a low incidence of post-operative complications. The soft consistency of the human pancreas poses a primary challenge for pancreatic surgeons. This study aimed to analyze the preliminary mechanical characteristics of the human pancreas to develop a realistic synthetic phantom for surgical simulations in the near future. Pancreatic specimens, comprehensive of the pancreatic parenchyma and main pancreatic duct, were collected during pancreatic resections and analyzed through nano-bio-indentation (BioindenterTM UNHT3 Bio, Anton Paar GmbH, Graz, Austria) to measure the elastic modulus. Comparisons were made between slow and fast loading rates, immediate and post-freezing analyses, and multipoint indentations. The results demonstrated that a slow loading rate (30 μN/min), immediate analysis, and multipoint measurements are crucial for obtaining accurate values of the elastic modulus of the human pancreas (1.40 ± 0.47 kPa). In particular, the study revealed that analysis after freezing could impact the outcomes of the indentation. Moreover, the study suggested that both the pancreatic parenchyma and the main pancreatic duct should be analyzed to achieve a more precise and comprehensive definition of the. mechanical features of the pancreas. These preliminary findings represent the initial steps toward defining the consistency and mechanical characteristics of human pancreatic tissue with the goal of creating a realistic synthetic phantom.

Pancreatology 2023; 23:843-851. [PMID: 37739874 DOI: 10.1016/j.pan.2023.09.079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 08/08/2023] [Accepted: 09/09/2023] [Indexed: 09/24/2023]
Abstract
BACKGROUND The incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) after central pancreatectomy (CP) is high, yet an effective predictive method is currently lacking. This study aimed to predict CR-POPF after CP by utilizing existing fistula risk scores (FRSs) for pancreaticoduodenectomy (PD) and distal pancreatectomy (DP). METHODS A retrospective analysis was conducted on patients undergoing CP at our institution between January 2010 and July 2022. The primary outcome was CR-POPF (grade B/C) according to the 2016 International Study Group of Pancreatic Surgery definition. To establish predictive models for CR-POPF after CP, we combined the FRSs for PD and DP using a calculation formula that considers the probability of the union of two events. As a result, we obtained twelve central FRS (C-FRS) models. The performance of each C-FRS was assessed using the area under the curves (AUC) and calibration plots. RESULTS A total of 115 patients undergoing CP were included. Among them, 38 (33%) were male, with a median age of 53 years. CR-POPF occurred in 35 (30.4%) patients, specifically 33 (28.7%) with grade B and 2 (1.7%) with grade C. Multivariate analysis showed that body mass index (BMI) [odds ratio (OR) 1.260, 95% confidence interval (CI) 1.039-1.528, P = 0.019), pancreatic thickness at the cephalic transection site (OR 1.228, 95% CI 1.074-1.405, P = 0.003), cephalic main pancreatic duct (MPD) size (OR 41.872, 95%CI 7.614-230.265, P < 0.001), and distal MPD size (OR 0.142, 95% CI 0.036-0.561, P = 0.005) were independent predictive factors for CR-POPF. Discrimination was generally acceptable for all C-FRS models, with an AUC ranging from 0.748 (DISPAIR-a-FRS: 95% CI, 0.659-0.824) to 0.847 (Intraop-D-a-FRS: 95% CI, 0.768-0.907). The models were calibrated with adequate Brier scores ranging from 0.157 to 0.183. The performance in all subgroups was similar as that of the entire cohort. Three preoperative risk groups (low, intermediate, and high) were identified based on the clinical applicability of the Preop-D-Roberts-FRS, with corresponding incidences of CR-POPF as 0% (0/24), 30% (21/70), and 66.7% (14/21), respectively. CONCLUSION The derived C-FRS models show potential for accurately predicting the development of CR-POPF after CP. However, further validation studies are required to determine the most effective model. In the meantime, the Preop-D-Roberts-FRS is recommended for clinical practice due to its ease of use and preoperative predictability.

Abstract
Pancreatic fistulas are highly feared complications following surgery on or near the pancreas, abdominal trauma, or severe inflammation. These fistulas arise from leaks in the pancreatic ductal system, leading to various complications such as abscesses, delayed gastric emptying, and hemorrhage. Severe cases present with sepsis or organ failure, dramatically increasing mortality and morbidity. Risk factors include smoking, high BMI, male gender, age, and surgery-related factors like prolonged operation time and non-ligation of the main pancreatic duct. Therefore, treatment options and preventive measurements have become a hot topic in recent years. Studies have investigated the use of fibrin sealants, different closure methods, and less invasive surgical techniques. Treatment options consist of conservative measurements and the use of percutaneous drainage, prophylactic transpapillary stenting, and surgery in severe cases. As EUS has become widely available, transmural stenting started to influence the management of pancreatic fluid collections (PFCs). However, studies on its use for the management of pancreatic fistulas are lacking. Medical treatment options like somatostatin analogs and pasireotide have been investigated but yielded mixed results.

Abstract
In elective pancreatic surgery, somatostatin-analogues pasireotide and octreotide are variably used to reduce postoperative complications, but knowledge on their role in pancreas transplantation is limited. This study compared pasireotide and octreotide for their association with complications after simultaneous pancreas-kidney transplantation (SPK). This retrospective study included consecutive patients undergoing SPK's from July 2013 to July 2022. Between July 2013 and April 2020, octreotide was administered 0.1 mg s.c. once daily and between May 2020 and July 2022 pasireotide was administered 0.9 mg twice daily, both until third postoperative day. Complications within 90 days postoperatively were collected, and reoperation rate and Comprehensive Complication index (CCI) ≥ 33.7 (morbidity equal to one reoperation) were used as primary outcomes. Of the 213 patients undergoing SPK, 150 patients received octreotide and 63 pasireotide. Baseline characteristics were comparable. Reoperation rate was 25.3% (n = 38) and 17.5% (n = 11) (p = 0.213) and rate of CCI ≥ 33.7 was 40.7% (n = 61) and 30.2% (n = 19) (p = 0.148) in octreotide and pasireotide groups, respectively. When adjusted with donor BMI, pancreas donor risk index, and donor sex, receiving pasireotide translated into OR 0.49 (95% CI: 0.25-0.96 p = 0.037) for CCI ≥ 33.7. Pasireotide was independently associated with lower postoperative morbidity within 90 days of SPK compared to octreotide.

Abstract
BACKGROUND AND OBJECTIVE Postoperative pancreatic fistula (POPF) is the leading cause of morbidity and early mortality in patients undergoing pancreatic resection. In addition, recent studies have identified postoperative acute pancreatitis (POAP) as an independent contributor to morbidity. Most perioperative mitigation strategies experimented for POPF have been shown to be in vain with no consensus on the best perioperative management. Clinical prediction models have been developed with the hope of identifying high POPF risk patients with the leading idea of finding subpopulations possibly benefiting from pre-existing or novel mitigation strategies. The aim of this review was to map out the existing prediction modeling studies to better understand the current stage of POPF prediction modeling, and the methodology behind them. METHODS A narrative review of the existing POPF prediction model studies was performed. Studies published before September 2022 were included. RESULTS While the number of POPF prediction models for pancreatoduodenectomy has increased, none of the currently existing models stand out from the crowd. For distal pancreatectomy, two unique POPF prediction models exist, but due to their freshness, no further external validation or adoption in clinics or research has been reported. There seems to be a lack of adherence to correct methodology or reporting guidelines in most of the studies, which has rendered external validity-if assessed-low. Few of the most recent studies have demonstrated preoperative assessment of pancreatic aspects from computed tomography (CT) scans to provide relatively strong predictors of POPF. CONCLUSIONS Main goal for the future would be to reach a consensus on the most important POPF predictors and prediction model. At their current state, few models have demonstrated adequate transportability and generalizability to be up to the task. Better understanding of POPF pathophysiology and the possible driving force of acute inflammation and POAP might be required before such a prediction model can be accessed.

Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) is a common complication after pancreaticoduodenectomy (PD). However, whether irrigation-suction (IS) decreases the incidence and severity of CR-POPF has not yet been well elucidated. METHODS One hundred and twenty patients with planned PD were enrolled in the study at a high-volume pancreatic center in China from August 2018 to January 2020. A randomized controlled trial (RCT) was conducted to evaluate whether irrigation-suction (IS) decreases the incidence and severity of CR-POPF and other postoperative complications after PD. The primary endpoint was the incidence of CR-POPF, and the secondary endpoints were other postoperative complications. RESULTS Sixty patients were assigned to the control group and 60 patients to the IS group. The IS group had a comparable POPF rate (15.0% vs. 18.3%, p = 0.806) but a lower incidence of intra-abdominal infection (8.3% vs. 25.0%, p = 0.033) than the control group. The incidences of other postoperative complications were comparable in the two groups. The subgroup analysis for patients with intermediate/high risks for POPF also showed an equivalent POPF rate (17.0% vs. 20.4%, p = 0.800) and a significantly decreased incidence of intra-abdominal infection (8.5% vs. 27.8%, p = 0.020) in the IS group than that in the control group. The logistic regression models indicated that POPF was an independent risk factor for intra-abdominal infection (OR 0.049, 95% CI 0.013-0.182, p = 0.000). CONCLUSIONS Irrigation-suction near pancreaticojejunostomy does not reduce the incidence or severity of postoperative pancreatic fistula but decreases the incidence of intra-abdominal infection after pancreaticoduodenectomy.

Abstract
The choice of the most appropriate suture threads for pancreatic anastomoses may play an important role in reducing the incidence of post-operative pancreatic fistula (POPF). The literature on this topic is still not conclusive. The aim of this study was to analyze the mechanical characteristics of suture materials to find the best suture threads for pancreatic anastomoses. A single-axial electromagnetic actuation machine was used to obtain the stress–deformation relationship curves and to measure both the ultimate tensile strength (UTS) and the Young’s modulus at the 0–3% deformation range (E0–3) of four different suture materials (Poliglecaprone 25, Polydioxanone, Polyglactin 910, and Polypropylene) at baseline and after incubation in saline solution, bile, and pancreatic juice for 1, 3, and 7 days. Polydioxanone and Polypropylene showed stable values of UTS and E0–3 in all conditions. Polyglactin 910 presented significant UTS and E0–3 variations between different time intervals in all types of liquids analyzed. Poliglecaprone 25 lost half of its strength in all biological liquids analyzed but maintained low E0–3 values, which could reduce the risk of lacerations of soft tissues. These results suggest that Polydioxanone and Poliglecaprone 25 could be the best suture materials to use for pancreatic anastomoses. In vivo experiments will be organized to obtain further confirmations of this in vitro evidence.

Abstract
INTRODUCTION Pancreatic resections for malignant or benign diseases are associated with major morbidity and changes in physiology. To reduce perioperative complications and enhance recovery, many types of perioperative medical management have been introduced. The aim of this study was to provide an evidence-based overview on the best perioperative drug treatment. METHODS The electronic bibliographic databases Medline, Embase, CENTRAL, and Web of Science were systematically searched for randomized controlled trials (RCT) evaluating perioperative drug treatments in pancreatic surgery. The investigated drugs were somatostatin analogues, steroids, pancreatic enzyme replacement therapy (PERT), prokinetic therapy, antidiabetic drugs, and proton pump inhibitors (PPI). Targeted outcomes in each drug category were meta-analyzed. RESULTS A total of 49 RCT were included. The analysis of somatostatin analogues showed a significantly lower incidence of postoperative pancreatic fistula (POPF) in the somatostatin group compared to the control group (OR 0.58, 95% CI: 0.45 to 0.74). The comparison of glucocorticoids versus placebo showed significantly less POPF in the glucocorticoid group (OR 0.22, 95% CI: 0.07 to 0.77). There was no significant difference in DGE when erythromycin was compared to placebo (OR 0.33, 95% CI: 0.08 to 1.30). The other investigated drug regimens could only be analyzed qualitatively. CONCLUSION This systematic review provides a comprehensive overview on perioperative drug treatment in pancreatic surgery. Some often-prescribed perioperative drug treatments lack high quality evidence and further research is needed.

Abstract
AIM Laparoscopic pancreaticojejunostomy is among the most difficult and high-risk operations. Surgeons with low or moderate seniority rarely are allowed to perform this surgery in clinics. Therefore, there is an urgent need to develop a reliable simulation training model focused on laparoscopic pancreaticojejunostomy and an effective stepwise training program. METHODS Surgeons with different working experiences or exposure to different training programs at Sir Run Run Shaw Hospital were divided into four groups. Each was required to perform laparoscopic pancreaticojejunostomy using a designed three-dimensional dry lab model. All surgeons' baseline characteristics and surgical performance, including operation time and score, were recorded and analysed. The authenticity of the model was evaluated by four senior surgeons. RESULTS The surgeon group with higher seniority had an older average age, longer working time, and had completed more laparoscopic cholecystectomy and laparoscopic common bile duct exploration procedures. Meanwhile, the surgeon group with higher seniority presented better operation performance, including shorter operation time and higher operation score in their initial simulation training. Resident surgeons who underwent stepwise training with the laparoscopic biliary-enteric anastomosis training program showed better initial performance than resident surgeons who underwent stepwise training with the laparoscopic basic suture training program. After repeated training, the surgeons showed improved surgical performance. CONCLUSION Our pancreaticojejunostomy model showed a good degree of discernibility, as surgeons with more experience performed better with the model for their initial simulation training in laparoscopic pancreaticojejunostomy. Stepwise training of the laparoscopic biliary-enteric anastomosis training program helped surgeons obtain a better initial performance, and repeated simulation training on this model improved the surgeon's operative performance.

Development and external validation of DISPAIR fistula risk score for clinically relevant postoperative pancreatic fistula risk after distal pancreatectomy. Br J Surg 2022; 109:1131-1139. [PMID: 35983583 PMCID: PMC10364701 DOI: 10.1093/bjs/znac266] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 05/01/2022] [Accepted: 07/14/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Highly utilized risk scores for clinically relevant postoperative pancreatic fistula (CR-POPF) have guided clinical decision-making in pancreatoduodenectomy. However, none has been successfully developed for distal pancreatectomy. This study aimed to develop and validate a new fistula risk score for distal pancreatectomy. METHODS Patients undergoing distal pancreatectomy at Helsinki University Hospital, Finland from 2013 to 2021, and at Karolinska University Hospital, Sweden, from 2010 to 2020, were included retrospectively. The outcome was CR-POPF, according to the 2016 International Study Group of Pancreatic Surgery definition. Preoperative clinical demographics and radiological parameters such as pancreatic thickness and duct diameter were measured. A logistic regression model was developed, internally validated with bootstrapping, and the performance assessed in an external validation cohort. RESULTS Of 668 patients from Helsinki (266) and Stockholm (402), 173 (25.9 per cent) developed CR-POPF. The final model consisted of three variables assessed before surgery: transection site (neck versus body/tail), pancreatic thickness at transection site, and diabetes. The model had an area under the receiver operating characteristic curve (AUROC) of 0.904 (95 per cent c.i. 0.855 to 0.949) after internal validation, and 0.798 (0.748 to 0.848) after external validation. The calibration slope and intercept on external validation were 0.719 and 0.192 respectively. Four risk groups were defined in the validation cohort for clinical applicability: low (below 5 per cent), moderate (at least 5 but below 30 per cent), high (at least 30 but below 75 per cent), and extreme (75 per cent or more). The incidences in these groups were 8.7 per cent (11 of 126), 22.0 per cent (36 of 164), 63 per cent (57 of 91), and 81 per cent (17 of 21) respectively. CONCLUSION The DISPAIR score after distal pancreatectomy may guide decision-making and allow a risk-adjusted outcome comparison for CR-POPF.

Abstract
BACKGROUND Delayed gastric emptying (DGE) following elective distal pancreatectomy (DP) is poorly known. This study aimed to report incidence of DGE following DP, to identify its predisposing factors, and to assess its impact on hospital stay. METHODS Patients who had elective DP without additional organ or vascular resection (2012-2017) in two academic hospitals were included. Factors predisposing to DGE, defined according to the International Study Group of Pancreatic Surgery, were identified by multivariate analysis. A systematic review was performed to evaluate DGE incidence following elective DP. RESULTS 311 elective DPs were performed. Three perioperative mortalities (1.0%) were unrelated to DGE. DGE occurred in 31 (10.0%) patients (grade A = 21, grade B = 7, grade C = 3) with a median hospital stay of 16 (13-22) days versus 10 (7-14) without DGE (p < 0.001). In multivariate analysis, predisposing factors of DGE were age>75 years (OR = 4.32 [1.53-12.19]; p = 0.006), open approach (OR = 2.97 [1.1-8]; p = 0.031) and POPF grade B-C (OR = 2.54 [1.05-6.1]; p = 0.038). The systematic review identified 7 series including 876 patients with an overall 8.1% DGE incidence. CONCLUSION DGE complicates around 10% of elective DP. Laparoscopic approach and prevention of POPF should be encouraged to reduce DGE incidence.

Somatostatin analogues for the prevention of pancreatic fistula after open pancreatoduodenectomy: A nationwide analysis. Pancreatology 2022; 22:421-426. [PMID: 35304104 DOI: 10.1016/j.pan.2022.03.006] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 02/02/2022] [Accepted: 03/07/2022] [Indexed: 12/11/2022]
Abstract
BACKGROUND Somatostatin analogues (SA) are currently used to prevent postoperative pancreatic fistula (POPF) development. However, its use is controversial. This study investigated the effect of different SA protocols on the incidence of POPF after pancreatoduodenectomy in a nationwide population. METHODS All patients undergoing elective open pancreatoduodenectomy were included from the Dutch Pancreatic Cancer Audit (2014-2017). Patients were divided into six groups: no SA, octreotide, lanreotide, pasireotide, octreotide only in high-risk (HR) patients and lanreotide only in HR patients. Primary endpoint was POPF grade B/C. The updated alternative Fistula Risk Score was used to compare POPF rates across various risk scenarios. RESULTS 1992 patients were included. Overall POPF rate was 13.1%. Lanreotide (10.0%), octreotide-HR (9.4%) and no protocol (12.7%) POPF rates were lower compared to the other protocols (varying from 15.1 to 19.1%, p = 0.001) in crude analysis. Sub-analysis in patients with HR of POPF showed a significantly lower rate of POPF when treated with lanreotide (10.0%) compared to no protocol, octreotide and pasireotide protocol (21.6-26.9%, p = 0.006). Octreotide-HR and lanreotide-HR protocol POPF rates were comparable to lanreotide protocol, however not significantly different from the other protocols. Multivariable regression analysis demonstrated lanreotide protocol to be positively associated with a low odds-ratio (OR) for POPF (OR 0.387, 95% CI 0.180-0.834, p = 0.015). In-hospital mortality rates were not affected. CONCLUSION Use of lanreotide in all patients undergoing pancreatoduodenectomy has a potential protective effect on POPF development. Protocols for HR patients only might be favorable too. However, future studies are warranted to confirm these findings.

Abstract
Background Pancreatic fibrosis and fatty infiltration are associated with postoperative pancreatic fistula (POPF), but accurate preoperative assessment remains a challenge. Iodine concentration (IC) and fat fraction derived from dual-energy CT (DECT) may reflect the amount of fibrosis and steatosis, potentially enabling the preoperative prediction of POPF. Purpose To identify multiphasic DECT-derived IC and fat fraction that improve the prediction of POPF risks compared with contrast-enhanced CT attenuation values and to evaluate the underlying histopathologic changes. Materials and Methods This retrospective study included patients who underwent pancreatoduodenectomy and DECT (including pancreatic parenchymal, portal venous, and delayed phase scanning) between January 2020 and December 2020. The relationships of the quantitative DECT-derived IC and fat fraction, along with CT attenuation values from enhanced images with POPF risk, were analyzed with logistic regression analysis. The predictive performance of the IC was compared with that of the CT values. The histopathologic underpinnings of IC were evaluated with multivariable linear regression analysis. Results A total of 107 patients (median age, 65 years; interquartile range, 57-70 years; 56 men) were included. Of these, 23 (21%) had POPF. The pancreatic parenchymal-to-portal venous phase IC ratio (adjusted odds ratio [OR], 13; 95% CI: 2, 162; P < .001) was an independent predictor of POPF occurrence. The accuracy of the pancreatic parenchymal-to-portal venous phase IC ratio in predicting POPF was higher than that of the CT value ratio in the same phases (78% vs 65%, P < .001). The pancreatic parenchymal-to-portal venous phase IC ratio was independently associated with pancreatic fibrosis (β = -1.04; 95% CI: -0.44, -1.64; P = .001). Conclusion A higher pancreatic parenchymal-to-portal venous phase IC ratio was associated with less histologic fibrosis and greater risk of POPF. © RSNA, 2022 Online supplemental material is available for this article.

Abstract
Background Recent studies have suggested postoperative acute pancreatitis (POAP) as a serious complication after pancreaticoduodenectomy (PD) and have speculated on its possible role in the pathogenesis of postoperative pancreatic fistula (POPF). This study aimed to assess the impact of POAP on post-PD outcomes and fistula risk score (FRS) performance in predicting POAP. Methods All PDs at Helsinki University Hospital between 2013 and 2020 were analysed. POAP was defined as a plasma amylase activity greater than the normal upper limit on postoperative day (POD) 1 and stratified as clinically relevant (CR)-POAP once C-reactive protein (CRP) reached or exceeded 180 mg/l, and non-CR-POAP once CRP was less than 180 mg/l on POD 2. The Comprehensive Complication Index (CCI) was used to assess total postoperative morbidity. Different FRSs were assessed using receiver operating characteristic curves. Results Of the 508 patients included, POAP occurred in 202 (39.8 per cent) patients, of whom 91 (17.9 per cent) had CR-POAP. The incidence of CR-POPF was 12.6 per cent (64 patients). Patients with non-CR-POAP had a similar morbidity to patients with no POAP (median CCI score 24.2 versus 22.6; P = 0.142), while CCI score was significantly higher (37.2) in patients with CR-POAP (P < 0.001). CR-POAP was associated with increased rates of CR-POPF, delayed gastric emptying, haemorrhage, and bile leak, while non-CR-POAP was associated only with CR-POPF. Ninety-day mortality was 1.6 per cent, 0.9 per cent, and 3.3 per cent in patients with no-POAP, non-CR-POAP, and CR-POAP, respectively. Updated alternative FRS showed the best performance in predicting CR-POAP (area under the curve 0.834). Conclusion CR-POAP was associated with a higher CCI score, suggesting CR-POAP as a distinct entity from non-CR-POAP. FRSs can be used to assess the risk of CR-POAP.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains a significant complication of pancreatic resection with recent evidence showing a strong association between post-operative pancreatitis and subsequent development of POPF. Incidence and severity of pancreatitis following endoscopic therapy has been effectively reduced with indomethacin prophylaxis, however further agents require evaluation. We present a systematic literature review and meta-analysis of the prophylactic treatment with corticosteroids or n-acetyl cysteine (NAC) of induced pancreatitis in rodent models. METHODS A systematic literature search was conducted using Pubmed, Medline, Embase and Cochrane library to identify eligible randomized control trials (RCT) involving animal models that examined NAC or corticosteroids. The primary outcome was the subsequent effect on serum amylase and IL-6 and the histopathological markers of severity such as pancreatic oedema and necrosis. RESULTS Four RCTs (n = 178) met inclusion criteria examining NAC and eight RCTs (n = 546) examining corticosteroid agents (dexamethasone, hydrocortisone, methylprednisolone). Prophylactic administration of all corticosteroid agents showed a net effect in favour of reducing markers of severity of pancreatitis. NAC showed a significant reduction in severity of amylase and necrosis. CONCLUSION The RCTs examined suggest that prophylactic administration of corticosteroid agents and NAC can reduce the severity of pancreatitis as indicated by histopathologic markers, serum amylase and IL-6 levels.

Abstract
BACKGROUND There is increasing evidence that peri-operative glucocorticosteroid can ameliorate the systemic response following major surgery. Preliminary evidence suggests peri-operative usage of glucocorticosteroid may decrease post-operative complications. These positive associations have been observed in a range of different operations including intra-abdominal, thoracic, cardiac, and orthopaedic surgery. This review aims to investigate the impact of peri-operative glucocorticosteroid in major pancreatic resections. METHODS A systematic review based on a search in Medline and Embase databases was performed. PRISMA guidelines for systematic reviews were followed. RESULTS A total of five studies were analysed; three randomised controlled trials and two retrospective cohort studies. The total patient population was 1042. The glucocorticosteroids used were intravenous hydrocortisone or dexamethasone. Three studies reported significantly lower morbidity in the peri-operative glucocorticosteroid group. The number needed to treat to prevent one major complication with hydrocortisone is four patients. Two studies demonstrated that dexamethasone was associated with a statistically significantly improved median overall survival in pancreatic cancer. CONCLUSION This is the first systematic review conducted to investigate the significance of peri-operative glucocorticosteroid in patients undergoing pancreatic resection. This review shows a correlation of positive outcomes with the administration of glucocorticosteroid in the peri-operative setting following a major pancreatic resection.. More randomised clinical trials are required to confirm if this is a true effect, as it would have significant implications.

Double purse-string telescoped pancreaticogastrostomy is not superior in preventing pancreatic fistula development in high-risk anastomosis: a 6-year single-center case-control study. Langenbecks Arch Surg 2021; 407:1073-1081. [PMID: 34782930 DOI: 10.1007/s00423-021-02376-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Accepted: 11/03/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE The double purse-string telescoped pancreaticogastrostomy (PG) technique has been suggested as an alternative approach to reduce the risk of postoperative pancreatic fistula (POPF). Its efficacity in high-risk situations has not yet been explored. This study compared the incidence of clinically relevant POPF (CR-POPF) between patients with high-risk anastomosis undergoing PG and those undergoing pancreaticojejunostomy (PJ). METHODS From 2013 to 2019, 198 consecutive patients with high-risk anastomosis, an updated alternative fistula risk score > 20%, and who underwent pancreatoduodenectomy with the PJ (165) or PG (33) technique were included. Optimal mitigation strategy (external stenting/octreotide omission) was applied for all patients. The primary endpoint was the incidence of CR-POPF. RESULTS The mean ua-FRS was 33%. CR-POPF (grade B/C) was found in 42 patients (21%) and postoperative hemorrhage in 30 (15%); the mortality rate was 4%. CR-POPF rates were comparable between the PJ (19%) and PG (33%) groups (P = 0.062). The PG group had a higher rate of POPF grade C (24% vs. 10%; P = 0.036), longer operative time (P = 0.019), and a higher transfusion rate (P < 0.001), even after a matching process on ua-FRS. In the multivariate analysis, the type of anastomosis (P = 0.88), body mass index (P = 0.47), or main pancreatic duct diameter (P = 0.7) did not influence CR-POPF occurrence. CONCLUSIONS For patients with high-risk anastomosis, the double purse-string telescoped PG technique was not superior to the PJ technique for preventing CR-POPF.

Abstract
Radical resection remains the only curative treatment option in pancreatic cancer. Postoperative pancreatic fistulas (POPF) occur in up to 30% of patients leading to prolonged hospital-stay, increased cost of care and morbidity and mortality. Mechanical properties of the pancreas are associated with POPF. The aim of this study is to analyze the role of extracellular matrix (ECM) and tissue mechanics in the risk of POPF. Biopsies of 41 patients receiving a partial pancreas-resection are analyzed. Clinical data, ECM components and mechanical properties are correlated with POPF. Preoperative cholestasis is correlated with reduced risk of POPF, which comes along with a dilatation of the pancreatic duct and significantly higher content of collagen I. Patients developing POPF exhibited a degenerated tissue integrity, with significantly lower content of fibronectin and a trend for lower collagen I, III, IV and hyaluronic acid. This correlated with a soft tactile sensation of the surgeon during the intervention. However, this was not reflected with tissue mechanics evaluated by ex vivo uniaxial compression testing, where a significantly higher elastic modulus and no effect on the stress relaxation time were found. In conclusion, patients with cholestasis seem to have a lower risk for POPF, and an increase in collagen I. A degenerated matrix with lower content of structural ECM components correlates with increased risk of POPF. However, ex vivo uniaxial compression testing failed to clearly explain the link of ECM properties and POPF.

Langenbecks Arch Surg 2021; 407:175-188. [PMID: 34370113 PMCID: PMC8847178 DOI: 10.1007/s00423-021-02290-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 07/23/2021] [Indexed: 01/08/2023]
Abstract
Purpose Postoperative pancreatic fistula (POPF) is a major complication of pancreatic surgery and can be fatal. Better stratification of patients into risk groups may help to select those who might benefit from strategies to prevent complications. The aim of this study was to validate ten prognostic scores in patients who underwent pancreatic head surgery. Methods A total of 364 patients were included in this study between September 2012 and August 2017. Ten risk scores were applied to this cohort. Univariate and multivariate analyses were performed considering all risk factors in the scores. Furthermore, the stratification of patients into risk categories was statistically tested. Results Nine of the scores (Ansorge et al., Braga et al., Callery et al., Graham et al., Kantor et al., Mungroop et al., Roberts et al., Yamamoto et al. and Wellner et al.) showed strong prognostic stratification for developing POPF (p < 0.001). There was no significant prognostic value for the Fujiwara et al. risk score. Histology, pancreatic duct diameter, intraabdominal fat thickness in computed tomography findings, body mass index, and C-reactive protein were independent prognostic factors on multivariate analysis. Conclusion Most risk scores tend to stratify patients correctly according to risk for POPF. Nevertheless, except for the fistula risk score (Callery et al.) and its alternative version (Mungroop et al.), many of the published risk scores are obscure even for the dedicated pancreatic surgeon in terms of their clinical practicability. There is a need for future studies to provide strategies for preventing POPF and managing patients with high-risk stigmata.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains the main cause of morbidity in patients after distal pancreatectomy. The objective of this study was to investigate whether an absorbable fibrin sealant patch could prevent POPF after distal pancreatectomy. METHODS A multicentre, patient-blinded, parallel-group randomized superiority trial was performed in seven Dutch hospitals. Allocation was done using a computer-generated randomization list with a 1 : 1 allocation ratio and concealed varying permuted block sizes. Pancreatic stump closure with a fibrin patch was compared with standard treatment in patients undergoing distal pancreatectomy. The primary endpoint was the development of grade B/C POPF. A systematic review and meta-analysis was performed which combined the present findings with all available evidence. RESULTS Between October 2010 and August 2017, 247 patients were enrolled. Fifty-four patients (22.2 per cent) developed a POPF, 25 of 125 patients in the patch group versus 29 of 122 in the control group (20.0 versus 23.8 per cent; P = 0·539). No related adverse effects were observed. In the meta-analysis, no significant difference was seen between the patch and control groups (19.7 versus 22.0 per cent; odds ratio 0.89, 95 per cent c.i. 0.60 to 1.32; P = 0·556). CONCLUSION Application of a fibrin patch to the pancreatic stump does not reduce the incidence of POPF in distal pancreatectomy. Future studies should focus on alternative fistula mitigation strategies, considering pancreatic neck thickness and duct size as risk factors.

Abstract
BACKGROUND Postoperative acute pancreatitis (POAP) emerges as a distinct pancreas-specific complication increasing both the risk and the burden of POPF after pancreatoduodenectomy. Among various risk factors, pancreas stump (PS) hypoperfusion might play a role in POAP occurrence but has never been investigated. The current study aimed at evaluating the feasibility of intraoperative fluorescence angiography (IOFA) of the PS using ICG and its association with POAP. METHODS Consecutive patients who underwent pancreatoduodenectomy for a periampullary tumor with pancreatojejunostomy and PS perfusion assessment using IOFA between January 2020 and November 2020 were prospectively included. Perioperative management and surgical strategy were standardized. IOFA of the pancreas stump was performed before fashioning pancreatojejunostomy. POAP was defined according to the Connor definition and was confirmed upon radiological blind review. Outcomes between patients with normally perfused and hypoperfused PS were compared. POAP was the primary endpoint. RESULTS Among 30 patients, nine patients (30%) developed POAP according to the Connor definition, and six patients (20%) had CT-confirmed POAP. Upon IOFA, six patients (20%) presented PS hypoperfusion; of which one patient underwent extended pancreatectomy further to the left. PS hypoperfusion was statistically associated with the occurrence of POAP (80% vs. 16%; p = 0.011) and CT-confirmed POAP (60% vs. 12%; p = 0.041). Clinically relevant POPF rate was 40% in case of PS hypoperfusion and 4% in case of normal PS perfusion (p = 0.064). CONCLUSIONS PS perfusion assessment using IOFA seems safe and reliable to anticipate POAP. PS IOFA could be considered as a potential tool for perioperative assessment of surgical risk after pancreatoduodenectomy.

Abstract
Question In distal pancreatectomy, is combined division of the splenic vein safe compared with separate division of the splenic vein? Findings In this noninferiority randomized clinical trial, the proportion of grade B/C pancreatic fistula in the separate division group was 27.1% vs 28.6% in the combined division group, demonstrating noninferiority of the combined division of the splenic vein against separate division. Meaning The safety of combined division of the splenic vein in distal pancreatectomy was established, such that the approach could be recommended with more confidence. Importance In distal pancreatectomy (DP), the splenic vein is isolated from the pancreatic parenchyma prior to being ligated and divided to prevent intra-abdominal hemorrhage from the splenic vein stump with pancreatic fistula (PF). Conversely, dissecting the splenic vein with the pancreatic parenchyma is easy and time-saving. Objective To establish the safety of combined division of the splenic vein compared with separate division of the splenic vein. Design, Setting, and Participants This study was designed as a multicenter prospective randomized phase 3 trial. All results were analyzed using the modified intent-to-treat set. Patients undergoing DP for pancreatic body and tail tumors were eligible for inclusion. Patients were randomly assigned between August 10, 2016, and July 30, 2019. Interventions Patients were centrally randomized (1:1) to either separate division of the splenic vein or combined division of the splenic vein. Main Outcomes and Measures The primary end point was the incidence of grade B/C PF, and the incidence of intra-abdominal hemorrhage was included as one of the secondary end points. Results A total of 318 patients were randomly assigned, and 2 patients were excluded as ineligible. Of the 316 remaining patients, 150 (50.3%) were male. The modified intent-to-treat population constituted 159 patients (50.3%) in the separate division group and 157 patients (49.7%) in the combined division group. In the modified intent-to-treat set, the proportion of grade B/C PF in the separate division group was 27.1% (42 of 155) vs 28.6% (44 of 154) in the combined division group (adjusted odds ratio, 1.108; 95% CI, 0.847-1.225; P = .047), demonstrating noninferiority of the combined division of the splenic vein against separate division. The incidence of postoperative intra-abdominal hemorrhage in the 2 groups was identical at 1.3%. Conclusions and Relevance This study demonstrated noninferiority of the combined division of the splenic vein compared with separate division of the splenic vein regarding safety. Thus, isolating the splenic vein from the pancreatic parenchyma is deemed unnecessary. Trial Registration ClinicalTrials.gov Identifier: NCT02871804

Abstract
BACKGROUND Simultaneous pancreas-kidney transplantation (SPK) carries a high risk of major postoperative complications, but knowledge on early warning signs and surrogate markers for postoperative complications is scarce. AIMS Our aim was to analyze the complication-predictive value of different laboratory tests in pancreas transplantation. MATERIALS & METHODS All SPKs in Finland between January 2010 and February 2020 were retrospectively analyzed. Levels of first three-day plasma amylase, drain fluid amylase, C-reactive protein, C-peptide, plasma trypsinogen, and white blood cell count were assessed for their performance predicting cumulative postoperative complications (assessed using the Comprehensive Complication Index) within 90 days from transplantation by using ROC analyses. RESULTS Of the 164 SPK patients included, 39 suffered at least one complication requiring laparotomy. First-day plasma amylase had the best value in predicting complications based on its high AUC value and easy clinical applicability, with an optimum cutoff of six times the upper normal limit. Negative predictive values (NPVs) and positive predictive values of this cutoff were 0.81 and 0.71 for any relaparotomy, and 0.91 and 0.71 for the Comprehensive Complication Index >47.7 (which equals the morbidity of two relaparotomies), respectively. CONCLUSION In conclusion, first-day plasma amylase could be able to detect patients at risk of complications after SPK.

Abstract
OBJECTIVE Prospective randomized investigation of the efficiency of somatostatin analogues and glucocorticoids in pancreatic fistula prevention after pancreatoduodenectomy by using. MATERIAL AND METHODS In period from December 2018 till March 2020 78 patients underwent pancreatoduodenectomy for pancreatobilliary tumors in department of abdominal surgery of National Medical Research Center of Surgery named after A.V. Vishnevsky. Intraoperative frozen section investigation of pancreatic functioning acinar structures (FAS) was held for all patients. 38 patients had more than 40% of FAC and were related with high risk of pancreatic fistula (PF), while 40 patients with less than 40% FAC were included in low risk of PF group. In both groups patients were randomized to main and control subgroups. In main subgroup of high risk group patients combination of somatostatin analogues and glucocorticoids was used, while in control subgroup patients received only somatostatin analogue. In low risk of PF group patients of main subgroup preventively got somatostatin analogue, while control group patients had no specific prophylaxis of PF. To assess the effect of drug prophylaxis on the development of pancreatic fistula we used logistic regression models with the inclusion of the drug use factor as an independent variable. RESULTS 25 patients were included in main subgroup of high risk group. Clinically relevant pancreatic fistula (CRPF) developed in 14 (56%) cases. From 13 patients of control subgroup CRPF developed in 5 (38%) cases. In main subgroup of low risk group 18 patients were included and 3 (16%) of them had CRPF. In control subgroup were 22 patients and there were no cases of CRPF. CONCLUSION In our series combination of somatostatin analogue and glucocorticoid didn't show efficiency in prevention of CRPF in high risk patients, although difference between subgroups wasn't statistically significant (p=0.34). In low risk group patients prophylactic use of somatostatin analogue also didn't show decline of CRPF incidence and the difference between subgroups also wasn't statistically significant (p=0.46).

Abstract
Background Post-operative pancreatic fistula (POPF) remains a critical complication after pancreatic resection. This prospective pilot study evaluates perioperative markers of pancreatitis and systemic inflammation to predict clinically relevant grade B/C-POPF (CR-POPF). Methods All patients undergoing pancreatic resection from December 2017 to April 2019 were prospectively enrolled. Surgical procedures and outcomes were correlated with perioperative blood markers. ROC analysis was performed to assess their predictive value for CR-POPF. Cut-offs were calculated with the Youden index. Results In total, 70 patients were analysed (43 pancreatoduodenectomies and 27 distal pancreatectomies). In-hospital/90-d mortality and morbidity were 5.7/7.1% (n = 4/n = 5) and 75.7% (n = 53). Major complications (Clavien–Dindo ≥ 3a) occurred in 28 (40.0%) patients, CR-POPF in 20 (28.6%) patients. Serum lipase (cut-off > 51U/L) and IL-6 (> 56.5 ng/l) on POD3 were significant predictors for CR-POPF (AUC = 0.799, 95%-CI 0.686–0.912 and AUC = 0.784, 95%-CI 0.668–0.900; combined AUC = 0.858, 95%-CI 0.758–0.958; all p < 0.001). Patients with both or one factor(s) above cut-off more frequently developed CR-POPF than cases without (100 vs. 50% vs. 7.5%, p < 0.001). This also applied for overall and severe complications (p = 0.013 and p = 0.009). Conclusions Post-operative pancreatitis and inflammatory response are major determinants for development of POPF. A combination of serum lipase and IL-6 on POD3 is a highly significant early predictor of CR-POPF and overall complications, potentially guiding patient management.
