Abstract
Pancreatic fluid collections (PFCs) are commonly encountered complications of acute and chronic pancreatitis. With the advancement of endoscopic ultrasound (EUS) techniques and devices, EUS-directed transmural drainage of symptomatic or infected PFCs has become the standard of care. Traditionally, plastic stents have been used for drainage, although lumen-apposing metal stents (LAMSs) are now favored by most endoscopists due to ease of use and reduced procedure time. While safety has been repeatedly demonstrated, follow-up care for these patients is critical as delayed adverse events of indwelling drains are known to occur.

Abstract
OBJECTIVES No comprehensive study has examined short- and long-term adverse outcomes of endoscopic ultrasound (EUS)-guided treatment of pancreatic fluid collections (PFCs) including walled-off necrosis (WON) and pseudocysts. METHODS In a multi-institutional cohort of 357 patients receiving EUS-guided treatment of PFCs (228 with WON and 129 with pseudocysts), we examined PFC type-specific risk factors for procedure-related adverse events (AEs), clinical failure, and recurrence. Odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) were computed using the logistic and Cox regression models, respectively, adjusting for potential confounders. RESULTS Adverse events were observed predominantly in WON, and risk factors were WON extension to the pelvis (OR 2.49; 95% CI 1.00-6.19) and endoscopic necrosectomy (OR 5.15; 95% CI 1.61-16.5). Risk factors for clinical failure in WON treatment included higher Charlson Comorbidity Index (OR for ≥3 vs. ≤2, 2.58; 95% CI 1.05-6.35), extension to the pelvis (OR 3.63; 95% CI 1.57-8.43), nonuse of a lumen-apposing metal stent (OR 2.88; 95% CI 1.10-7.54), and percutaneous drainage (OR 3.73; 95% CI 1.27-10.9). Patients with pseudocysts extending to the paracolic gutter and the need for more than two endoscopic/percutaneous procedures had ORs for clinical failure of 5.28 (95% CI 1.10-25.3) and 5.52 (95% CI 1.61-18.9), respectively. Pseudocysts requiring the multigateway approach were associated with a high risk of recurrence (HR 4.00; 95% CI 1.11-11.6). CONCLUSION The adverse outcomes at various phases of EUS-guided PFC treatment may be predictable based on clinical parameters. Further research is warranted to optimize treatment strategies for high-risk patients.

Endoscopic and surgical treatment of necrotizing pancreatitis-a comparison of short- and long-term outcome. Langenbecks Arch Surg 2024; 409:58. [PMID: 38347181 PMCID: PMC10861384 DOI: 10.1007/s00423-024-03244-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 01/29/2024] [Indexed: 02/15/2024]
Abstract
BACKGROUND Acute necrotizing pancreatitis is still related to high morbidity and mortality rates. Minimal-invasive treatment options, such as endoscopic necrosectomy, may decrease peri-interventional morbidity and mortality. This study aims to compare the initial operative with endoscopic treatment on long-term parameters, such as endocrine and exocrine functionality, as well as mortality and recurrence rates. METHODS We included 114 patients, of whom 69 were treated with initial endoscopy and 45 by initial surgery. Both groups were further assessed for peri-interventional and long-term parameters. RESULTS In the post-interventional phase, patients in the group of initial surgical treatment (IST) showed significantly higher rates of renal insufficiency (p < 0.001) and dependency on invasive ventilation (p < 0.001). The in-house mortality was higher in the surgical group, with 22% vs. 10.1% in the group of patients following initial endoscopic treatment (IET; p = 0.077). In long-term follow-up, the overall mortality was 45% for IST and 31.3% for IET (p = 0.156). The overall in-hospital stay and intensive care unit (ICU) stay were significantly shorter after IET (p < 0.001). In long-term follow-up, the prevalence of endocrine insufficiency was 50% after IST and 61.7% after IET (p = 0.281). 57.1% of the patients following IST and 16.4% of the patients following IET had persistent exocrine insufficiency at that point (p = < 0.001). 8.9% of the IET and 27.6% of the IST patients showed recurrence of acute pancreatitis (p = 0.023) in the long-term phase. CONCLUSION In our cohort, an endoscopic step-up approach led to a reduced in-hospital stay and peri-interventional morbidity. The endocrine function appeared comparable in both groups, whereas the exocrine insufficiency seemed to recover in the endoscopic group in the long-term phase. These findings advocate for a preference for endoscopic treatment of acute necrotizing pancreatitis whenever feasible.

Abstract
ABSTRACT Acute pancreatitis and management of its complications is a common consult for the acute care surgeon. With the ongoing development of both operative and endoscopic treatment modalities, management recommendations continue to evolve. We describe the current diagnostic and treatment guidelines for acute pancreatitis through the lens of acute care surgery. Topics, including optimal nutrition, timing of cholecystectomy in gallstone pancreatitis, and the management of peripancreatic fluid collections, are discussed. Although the management severe acute pancreatitis can include advanced interventional modalities including endoscopic, percutaneous, and surgical debridement, the initial management of acute pancreatitis includes fluid resuscitation, early enteral nutrition, and close monitoring with consideration of cross-sectional imaging and antibiotics in the setting of suspected superimposed infection. Several scoring systems including the Revised Atlanta Criteria, the Bedside Index for Severity in Acute Pancreatitis score, and the American Association for the Surgery of Trauma grade have been devised to classify and predict the development of the severe acute pancreatitis. In biliary pancreatitis, cholecystectomy prior to discharge is recommended in mild disease and within 8 weeks of necrotizing pancreatitis, while early peripancreatic fluid collections should be managed without intervention. Underlying infection or ongoing symptoms warrant delayed intervention with technique selection dependent on local expertise, anatomic location of the fluid collection, and the specific clinical scenario. Landmark trials have shifted therapy from maximally invasive necrosectomy to more minimally invasive step-up approaches. The acute care surgeon should maintain a skill set that includes these minimally invasive techniques to successfully manage these patients. Overall, the management of acute pancreatitis for the acute care surgeon requires a strong understanding of both the clinical decisions and the options for intervention should this be necessary.

Abstract
BACKGROUND Necrotizing pancreatitis (NP) may result de novo or following procedures such as ERCP or partial pancreatectomy (post-procedural), and may require surgical debridement. Video-assisted retroperitoneal debridement (VARD) is a standard approach for NP that employs a 5 cm incision with varying degrees of blind and open debridement. We describe our technique and outcomes of a modified VARD called laparoscopic-assisted pancreatic necrosectomy (LAPN) performed through a single 12 mm incision that uses direct laparoscopic visualization during debridement. METHODS At one medical center, all LAPN patients (2012-2020) were assessed for demographics, disease factors, and outcomes. Bivariate logistic regression analyses were performed to identify factors independently associated with recovery after LAPN for patients with de novo vs post-procedural necrosum. RESULTS Over 9 years, 60 patients underwent LAPN for NP. Median age was 57 years (IQR: 47-66) and 43 (69%) were men. Pancreas necrosum was de novo in 39 (63%) patients and post-procedural in 23 (37%). NP resolved with a median of 1 LAPN procedure and median hospitalization was 33 days. The LAPN major morbidity rate and in-hospital mortality rate were 47% and 5%. No significant differences were seen between NP etiology cohorts, although post-procedure NP patients trended towards a faster clinical recovery to baseline compared to de novo patients (193 vs 394 days; p-value = .07). CONCLUSIONS LAPN offers a smaller incision with excellent visualization and non-inferior outcomes, regardless of etiology, with likely faster recovery for patients with post-procedural vs de novo necrotizing pancreatitis.

Abstract
Objective Infection is a common complication of acute pancreatitis (AP). Klebsiella pneumoniae (KP) is one of the most common pathogens associated with nosocomial infections. Our study focuses on investigating the clinical characteristics and risk factors for death of Klebsiella pneumoniae infections in AP patients, further to quantify the prognosis of the patients, and provide evidence for guiding antibiotic use and improving prognosis. Methods The data of epidemiology, clinical manifestations and drug resistance rate with K. pneumoniae infections in AP patients from January 1, 2012 to August 30, 2022 were retrospectively collected. Logistic regression model and Cox regression model were, respectively, used to determine the risk factors for carbapenem-resistant Klebsiella pneumoniae (CRKP) acquisition and death. The nomogram prediction model was built by RMS software package to predict the 90-day survival rate. Results One hundred and twenty-six AP patients combined with K. pneumoniae infections, with a mortality rate of 34.9%. The most common infection sites were pancreas and peri-pancreas (54.8%), followed by lung (20.6%) and blood stream (18.3%). The resistance rate of K. pneumoniae to commonly used antibiotics in clinical practice was high, especially CRKP, which was only sensitive to sulfamethoxazole-trimethoprim (SMZ-TMP) and tigecycline (TGC) (resistance rates were 37.57% and 17.57%, respectively). Independent risk factors for CPKP acquisition were male (OR = 1.655, 95% CI 0.642-4.265, P = 0.017) and PICC/CVC implantation (OR = 3.157, 95% CI 1.223-8.147, P = 0.021). Independent risk factors for mortality included carbapenem resistance (HR = 2.556, 95% CI 1.011-6.462, P = 0.047), hemorrhage (HR = 2.392, 95% CI 1.104-5.182, P = 0.027), septic shock (HR = 3.022, 95% CI 1.312-6.959, P = 0.009), age >60 years (HR = 2.977, 95% CI 1.303-6.799, P = 0.01), creatinine >177μmol/L (HR = 2.815, 95% CI 1.075-7.369, P = 0.035). Conclusion K. pneumoniae infection has become a serious threat for AP patients, which recommends us more attention and active new strategies seeking.

Abstract
AIMS To determine time trends in the incidence and etiology of acute pancreatitis and identify predictors for in-hospital mortality. PATIENTS AND METHODS Retrospective study of 1722 patients with acute pancreatitis admitted to Akershus University Hospital between January 2000 and December 2017. Data were obtained from electronic patient files and computed tomography scans. We estimated a logistic regression model to assess differences in associations between patient characteristics and in-hospital mortality in two time periods, 2000-2009 (first period) and 2010-2018 (second period). RESULTS First attack of acute pancreatitis (FAAP) was identified in 1579 patients (91.7%). The incidence of FAAP increased from 20.1/100,000 during the first period to 27.7/100,000 in the second period (p = .011). Etiology showed no differences between the two time periods. Gallstone was the most frequent etiology (47.2%). In total, 187 patients (11.8%) had necrotizing pancreatitis; more in the second period compared to the first (14.2 vs. 7.7%; p < .001). The overall mortality rate was 3.9%. Mortality rates decreased for both inflammatory and necrotizing pancreatitis during the study period. Age and comorbidity according to Charlson Comorbidity Index (CCI) were predictors of in-hospital mortality (OR 1.07, 95% CI 0.07; 0.40 and 13.58, 95% CI 3.88; 47.52), as were alcohol and organ failure (OR 7.20, 95% CI 2.02; 25.67 and OR 34.15, 95% CI 8.94; 130.53, respectively). CONCLUSIONS The incidence of FAAP is increasing in southeast Norway. The etiology has remained unchanged over an 18-year period, with gallstones being the most frequent cause. The outcomes for both inflammatory and necrotic pancreatitis are improving.

Abstract
BACKGROUND AND AIMS Previous studies have demonstrated that the ideal time for drainage of walled-off pancreatic fluid collections is 4 to 6 weeks after their development. However, some pancreatic collections, notably infected pancreatic fluid collections, require earlier drainage. Nevertheless, the optimal timing of the first intervention is unclear, and consensus data are sparse. The aim of this study was to evaluate the clinical efficacy and safety of EUS-guided drainage of pancreatic fluid collections <4 weeks after development compared with ≥4 weeks after development. METHODS Search strategies were developed for PubMed, Embase, and Cochrane Library databases from inception. Outcomes of interest were technical success, defined as successful endoscopic placement of a lumen-apposing metal stent; clinical success, defined as a reduction in cystic collection size; and procedure-related adverse events. A random-effects model was used for analysis, and results are expressed as odds ratio (OR) with 95% confidence interval (CI). RESULTS Six studies (630 patients) were included in our final analysis, in which 182 patients (28.9%) were enrolled in the early drainage cohort and 448 patients (71.1%) in the standard drainage cohort. The mean fluid collection size was 143.4 ± 18.8 mm for the early cohort versus 128 ± 19.7 mm for the standard cohort. Overall, technical success was equal in both cohorts. Clinical success did not favor either standard drainage or early drainage (OR, .39; 95% CI, .13-1.22; P = .11). No statistically significant differences were found in overall adverse events (OR, 1.67; 95% CI, .63-4.45; P = .31) or mortality (OR, 1.14; 95% CI, .29-4.48; P = .85). Hospital stay was longer for patients undergoing early drainage compared with standard drainage (23.7 vs 16.0 days, respectively). CONCLUSIONS Both early (<4 weeks) and standard (≥4 weeks) drainage of walled-off pancreatic fluid collections offer similar technical and clinical outcomes. Patients requiring endoscopic drainage should not be delayed for 4 weeks.

[PMID: 36755332 PMCID: PMC9909852 DOI: 10.1186/s40001-023-01030-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 01/24/2023] [Indexed: 02/10/2023] Open
Abstract
BACKGROUND The currently preferred minimally invasive approaches have substantially improved outcomes of infected walled-off pancreatic necrosis (iWON). However, iWON with deep extension (iWONde) still poses a tricky challenge for sufficient necrosis evacuation by one stand-alone approach, often requiring repeated interventions. The aim of this study was to assess the effectiveness and safety of a minimal-access video-assisted retroperitoneal and/or transperitoneal debridement (hereafter called VARTD) in the management of iWONde. METHODS Patients who had developed an iWONde were recruited to receive the VARTD in this prospective single-arm study. The primary efficacy endpoint was clinical improvement up to day 28 after the VARTD, defined as a ≥ 75% reduction in size of necrotic collection (in any axis) on CT and clinical resolution of sepsis or organ dysfunction. The primary safety endpoint was a composite of major complications or death during follow-up. Six-month postdischarge follow-up was available. RESULTS Between July 18, 2018, and November 12, 2020, we screened 95 patients with necrotizing pancreatitis; of these, 21 iWONde patients (mean [SD] age, 42.9 [11.7] years; 10 [48%] women) were finally enrolled. The primary efficacy endpoint was achieved by most participants (14/21, 67%). No participants required repeated interventions. The primary safety endpoint occurred in six patients (29%). Except one in-hospital death attributable to repeated intra-abdominal hemorrhage, others were discharged without any major complication. CONCLUSIONS The VARTD approach appears to have a reasonable efficacy with acceptable complication rates and thus might be an option for improving clinical management of iWONde. TRIAL REGISTRATION This study is registered with Chinese Clinical Trial Registry (chictr.org.cn number, ChiCTR1800016950).

Abstract
Background Management of acute necrotising pancreatitis is often challenging for clinicians. Secondary infection of the necrotic collections leads to sepsis and warrants intervention. Minimally invasive techniques like catheter drainage have recently been proposed over more risky and morbid traditional open procedures. Factors that can predict successful catheter drainage of the necrotic pancreatic collection are still unclear and not well established. Materials and methods This study is designed as a retrospective cross-sectional observational study to investigate the association of 21 factors in predicting successful catheter drainage. Data from 30 patients admitted with acute necrotising pancreatitis treated with catheter drainage were collected and analysed. Twenty-one factors, including demographic variables, disease severity factors, drainage criteria, and morphological criteria on imaging, were studied for their predictive association with successful outcomes. Univariate analysis was done for each variable against the outcome. The study was conducted between December 2012 to March 2017. P-value <0.05 was considered statistically significant. Results Patients with no organ involvement responded better to primary catheter drainage. Patients with BMI>25 and multi-organ failure were poor candidates for primary catheter drainage. Clinically unwell patients with a Bedside Index for Severity in Acute Pancreatitis (BISAP) score of ≥4 had a negative outcome on catheter drainage and usually ended up in a surgical procedure or eventually succumbed to the disease. Other variables included in our study did not statistically associate with the success or failure of percutaneous catheter drainage. Conclusion BMI >25, multiple organ failure, and BISAP score ≥ 4 are independent negative predictors for the success of catheter drainage in infected necrotising pancreatitis. No organ failure showed a positive predictor for successful catheter drainage. Further studies are required to explore these predictive factors in a larger sample size to predict the success of catheter drainage in infected pancreatic necrosis.

Abstract
OBJECTIVE Gram-negative bacilli (GNB) are common pathogens of infection in severe acute pancreatitis (SAP), and their occurrence increases the mortality of SAP. Early identification of SAP severity and prognosis is of great significance to SAP treatment. This study explored risk factors for mortality in patients with SAP and GNB infection and established a model for early prediction of the risk of death in GNB-infected SAP patients. METHODS Patients diagnosed with SAP from January 1, 2016, to March 31, 2022, were included, and their baseline clinical characteristics were collected. Univariate logistic regression analysis was performed to screen for death related variables, and concurrently, a Boruta analysis was performed to identify potentially important clinical features associated with mortality. The intersection of the two results was taken for further multivariate logistic regression analysis. A logistic regression model was constructed according to the independent risk factor of death and then visualized with a nomogram. The performance of the model was further validated in the training and validation cohort. RESULTS A total of 151 patients with SAP developed GNB infections. Univariate logistic regression analysis identified 11 variables associated with mortality. The Boruta analysis identified 11 clinical features, and 4 out of 9 clinical variables: platelet counts (odds ratio [OR] 0.99, 95% confidence interval [CI] 0.99-1.00; p = 0.007), hemoglobin (OR 0.96, 95% CI 0.92-1; p = 0.037), septic shock (OR 6.33, 95% CI 1.12-43.47; p = 0.044), and carbapenem resistance (OR 7.99, 95% CI 1.66-52.37; p = 0.016), shared by both analyses were further selected as independent risk factors by multivariate logistic regression analysis. A nomogram was used to visualize the model. The model demonstrated good performance in both training and validation cohorts with recognition sensitivity and specificity of 96% and 80% in the training cohort and 92.8% and 75% in the validation cohort, respectively. CONCLUSION The nomogram can accurately predict the mortality risk of patients with SAP and GNB infection. The clinical application of this model allows early identification of the severity and prognosis for patients with SAP and GNB infection and identification of patients requiring urgent management thus allowing rationalization of treatment options and improvements in clinical outcomes.

Abstract
INTRODUCTION The heterogeneous nature of severe acute pancreatitis (SAP) renders decisions related to complications challenging. Central solid collections at the root of the mesentery are difficult to access with traditional techniques. Here we describe a case series of laparoscopic infracolic necrosectomy (ICN) and open or laparoscopic infracolic necrosectomy with Roux-en Y cystjejunostomy (ICN-RYCJ) for the management of complicated SAP. MATERIALS AND METHODS A retrospective analysis of a prospectively maintained database identified all patients treated with infracolic necrosectomy or drainage of pancreatic collections for complicated SAP between 2012 and 2021 inclusive at a single institution. RESULTS Forty patients were identified (median age 53 years)-ICN group 9 patients (median time to intervention-22 days) and ICN-RYCJ group 31 patients (median time to intervention-99 days). Two patients in ICN group underwent interval fistula-tract jejunostomy. Thirty-one patients had laparoscopic surgery and 9 patients underwent an open approach. Four patients required intervention post-operatively. Nineteen patients were discharged from follow-up at two years. CONCLUSION Infracolic approach with selective Roux-en Y cystjejunostomy, as a single or staged intervention, is an effective and safe operative option to add to the armamentarium of the pancreatic surgeon when dealing with complicated SAP not amenable to drainage/debridement by traditional techniques.

Abstract
In this article, an attempt was made to clarify the role of percutaneous endoscopic necrosectomy (PEN) in the interventional treatment of pancreatic necrosis. A comprehensive review of the current literature was performed to identify publications on the role of PEN in patients with consequences of acute necrotizng pancreatitis. The aim of the study was to review the literature on minimal invasive necrosectomy, with emphasis on PEN using esophageal self-expanding metal stents (SEMS). The described results come from 15 studies after a review of the current literature. The study group comprised 52 patients (36 men and 16 women; mean age, 50.87 (13-75) years) with walled-off pancreatic necrosis, in whom PEN using a self-expandable esophageal stent had been performed. PEN was successfully completed in all 52 patients (100%). PEN complications were observed in 18/52 (34.62%) patients. Clinical success was achieved in 42/52 (80.77%) patients, with follow-up continuing for an average of 136 (14-557) days. In conclusion, the PEN technique is potentially effective, with an acceptable rate of complications and may be implemented with good clinical results in patients with pancreatic necrosis.

Abstract
OBJECTIVES A minimally invasive step-up (MIS) approach for management of necrotizing pancreatitis (NP) has been associated with reduced morbidity and mortality compared with open surgical techniques. We sought to evaluate bleeding complications in NP patients treated with a MIS approach and to describe the management and outcomes of these events. METHODS An observational, cohort study was performed using a prospectively maintained NP database at a tertiary referral center from 2013 to 2019. RESULTS Of 119 NP patients, 13% suffering bleeding events, and 18% underwent an intervention. There was a 6-fold higher mortality rate in patients with bleeding events (n = 3; 18.8%) compared with those without (n = 3; 2.9%) ( P = 0.031). The most common intervention for hemorrhage control was endovascular coil embolization (75%), which was successful 88% of the time. Seven patients underwent prophylactic vascular intervention, which was 100% successful in preventing bleeding events from the embolized vessel. CONCLUSIONS Bleeding events in NP patients treated with a MIS approach are associated with a 6-fold increase in mortality. Endovascular intervention is an effective strategy for the management of bleeding events. Prophylactic embolization may be an effective technique for reducing bleeding complications.

Abstract
BACKGROUND Index cholecystectomy is the standard of care for gallstone pancreatitis. Hospital-level operative resources and implementation of an acute care surgery (ACS) model may impact the ability to perform index cholecystectomy. We aimed to determine the influence of structure and process measures related to operating room access on achieving index cholecystectomy for gallstone pancreatitis. METHODS In 2015, we surveyed 2811 US hospitals on ACS practices, including infrastructure for operative access. A total of 1690 hospitals (60%) responded. We anonymously linked survey data to 2015 State Inpatient Databases from 17 states using American Hospital Association identifiers. We identified patients ≥ 18 years who were admitted with gallstone pancreatitis. Patients transferred from another facility were excluded. Univariate and multivariable regression analyses, clustered by hospital and adjusted for patient factors, were performed to examine multiple structure and process variables related to achieving an index cholecystectomy rate of ≥ 75% (high performers). RESULTS Over the study period, 5656 patients were admitted with gallstone pancreatitis and 70% had an index cholecystectomy. High-performing hospitals achieved an index cholecystectomy rate of 84.1% compared to 58.5% at low-performing hospitals. On multivariable regression analysis, only teaching vs. non-teaching hospital (OR 2.91, 95% CI 1.11-7.70) and access to dedicated, daytime operative resources (i.e., block time) vs. no/little access (OR 1.93, 95% CI 1.11-3.37) were associated with high-performing hospitals. CONCLUSIONS Access to dedicated, daytime operative resources is associated with high quality of care for gallstone pancreatitis. Health systems should consider the addition of dedicated, daytime operative resources for acute care surgery service lines to improve patient care.

Abstract
OBJECTIVE Patients with acute pancreatitis (AP) are at risk for extrapancreatic complications (EPCs) when admitted to the intensive care unit (ICU). We assessed the prevalence of EPCs in non-ICU AP patients and their outcomes. METHODS We retrospectively studied EPCs in non-ICU AP patients between 2008 and 2018. Outcomes such as length of stay (LOS), inpatient mortality, and 30-day readmission rates were compared between those with and without EPC. RESULTS Of the 830 AP patients, 151 (18.1%) had at least 1 EPC. These included urinary tract infection (15.9%), Clostridium difficile infection (17.2%), pneumonia (7.3%), bacteremia (17.2%), acute kidney injury requiring dialysis (3.3%), gastrointestinal bleeding (12.5%), alcohol withdrawal (24.5%), delirium (14.5%), and falls (1.32%). Patients with EPC had increased mean LOS (6.98 vs 4.42 days; P < 0.001) and 30-day readmissions (32.5% vs 19%; P < 0.001). On multivariate regression, EPCs were independently associated with higher LOS (odds ratio, 1.45 [95% confidence interval, 1.36-1.56]; P < 0.001) and 30-day readmissions (odds ratio, 1.94 [95% confidence interval 1.28-2.95]; P < 0.001). CONCLUSIONS The EPCs are common among noncritical AP patients and contribute to poor outcomes like increased LOS and 30-day readmissions.

Abstract
Walled-off pancreatic necrosis (WOPN) is one of the local complications of acute pancreatitis (AP). Several interventional techniques have been developed over the last few years. The purpose of this narrative review is to explore such methodologies, with specific focus on endoscopic drainage and direct endoscopic necrosectomy (DEN), through evaluation of their indications and timing for intervention. Findings indicated how, after the introduction of lumen-apposing metal stents (LAMS), DEN is becoming the favorite technique to treat WOPN, especially when large solid debris or infection are present. Additionally, DEN is associated with a lower adverse events rate and hospital stay, and with improved clinical outcome.

Abstract
BACKGROUND Pancreatic necrosectomy outcomes have been studied extensively; however, long-term results of these procedures have not been well characterized. Our study aimed to assess the outcomes at and after discharge for patients following necrosectomy. METHODS Data from patients undergoing pancreatic necrosectomy at a single tertiary referral hospital from January 1, 2007, to June 1, 2019 were retrospectively analyzed. Patients were stratified into an open pancreatic necrosectomy (OPN) and an endoscopic pancreatic necrosectomy (EPN) group. RESULTS Cohorts were composed of an OPN (n = 30) and EPN (n = 31) groups with a mean follow-up of 22 and 13.5 months, respectively. There was no statistically significant difference in the demographics or etiology of disease; however, the presence of severe sepsis and elevated BISAP scores was significantly higher in the OPN group (40% vs 13% p = .016, 37% vs 10% p = .012, respectively). There was no significant difference in discharge parameters or disposition other than a higher need for wound care in the OPN group (14% vs 0% p =< .0001). No significant difference in the number of patients who returned to baseline, 12-month ED visits, 12-month readmissions, medical comorbidities, or long-term survival was noted. CONCLUSIONS Previous studies have demonstrated that OPN patients have a higher severity of disease and higher inpatient mortality; however, this does not hold true once the acute phase of the illness has passed. Long-term medical comorbidities and survival of patients with necrotizing pancreatitis who endure the primary insult do not differ in long term, regardless of the debridement modality performed for source control.

Abstract
Pancreatic fluid collections are surrounded by a wall of granulation tissue and may contain necrotic debris. They occur following a severe acute pancreatitis and most of the cases resolve spontaneously after several weeks. However, their management may lead to a very hardto-treat condition, requiring a multidisciplinary approach. During the last decades we assisted to a change of paradigm involving Endoscopic Ultrasonography, from a pure diagnostic technique to an interventional-therapeutic one, allowing an effective, safe and less invasive approach than other existing treatment standards, historically consisting of surgical and percutaneous drainage. Treatment of pancreatic fluid collections is indicated if they become infected or symptomatic. Over the past years, exponential developments were done in interventional endoscopic approach, making it the first line suggested modality. The use of endoscopic ultrasound allows assessment of the collection, even when it is not directly bulging on gastrointestinal wall, creation of an internal fistulous tract, checking for surrounding vessels with the use of Doppler, and deployment of a stent avoiding the discomfort of external tubes. Several types of stent have been used for endoscopic drainage: plastic double pigtail stents, fully covered self-expanding metal stents and, more recently, lumen apposing metal stents, which are considered revolutionary because of their two-side flanges and wide and short internal channel, a new design that made easier direct endoscopic necrosectomy. This review aims to go through currently available literature on the diagnostic and therapeutic role of Endoscopic Ultrasonography to handle pancreatic fluid collections.

Abstract
Walled-off pancreatic necrosis (WON) can develop in the late phase of necrotizing pancreatitis. When the WON is accompanied by an infection in the necrotic bed, it becomes a life-threatening complication. Open necrosectomy with drainage has been the standard treatment; however, it is associated with a significant morbidity and high mortality. Therefore, minimally invasive therapeutic alternatives are in demand. Recently, a new treatment algorithm for necrotizing pancreatitis, known as the step-up approach, has been proposed. The initial report on it consisted of percutaneous drainage followed by, if necessary, a minimally invasive retroperitoneal necrosectomy. However, the endoscopic step-up approach, which consists of EUS-guided transluminal drainage followed by, if necessary, endoscopic necrosectomy, was later introduced. Recent studies have suggested that an endoscopic step-up approach might be more advantageous than a minimally invasive surgical step-up approach. A lumen apposing metal stent (LAMS) with a cautery-enhanced delivery system is currently preferred over the conventional plastic stents for endoscopic interventions, because it decreases the technical difficulty of the procedure and may obviate the need for an adjunctive debridement procedure. However, some recent findings suggest that LAMS could be associated with a higher risk of stent-related complications than conventional plastic stents, especially in patients with long-term placement. Therefore, early removal of LAMS at 3 weeks post-intervention is proposed if the WON is resolved on CT examination. Thus, endoscopic interventions have emerged as a key player in the management of WON. However, multidisciplinary treatment approaches should be considered because the endoscopic approach has limitations in treating complicated WON.

Abstract
Background The main purpose of this study was to review the trends in management of patients presenting with acute necrotizing pancreatitis (ANP) over the last seven years and its effect on morbidity and mortality. Methods A cross-sectional study was conducted on all patients presenting with the diagnosis of acute necrotizing pancreatitis to the Aga Khan University Hospital in between the year 2008-2015. The study population was broadly categorized in to two groups based on the way these were managed. The first group consisted of patient who underwent surgery for acute necrotizing pancreatitis while the second group was composed of those patients with necrotizing pancreatitis who were conservatively managed. Patient outcomes were assessed in terms of hospital stay, complication rates and in-hospital mortality. Data was analyzed using SPSS version 20. Comparison of outcomes between two groups was done using chi-square test, Fischer exact test or t-test wherever applicable. A p-value of less than 0.05 was considered statistically significant. Results A total of n = 110 patients were included in the study with 68% (n = 75) males and 32% (n = 35) females. Nasojejunal route was found to be the most commonly utilized route of feeding in these patients consisting of around 49% (n = 54) patients with forty percent (n = 44) tolerating direct oral diet. The outcomes in both these groups in terms of hospital stay, complication rate, and in hospital mortality were not found to be statistically significant. The conservative group however was significant in terms of cost-effectiveness which was shown by a p value of (0.035). The management of this clinically important disease over the years showed an increased trend towards conservative approach in our institute. Conclusion Our study further substantiates the recent global trend of conservative approach towards managing patients with acute necrotizing pancreatitis as reflected in the recent available literature. Therefore surgeons of the developing world need to evolve and adapt to these new measures for better outcomes in patient management.

When Should We Perform Endoscopic Drainage and Necrosectomy for Walled-Off Necrosis? J Clin Med 2020; 9:jcm9124072.

Abstract
Endoscopic drainage and necrosectomy are now accepted treatment approaches for patients with symptomatic walled-off pancreatic necrosis (WON). The current recommendations advocate step-up approaches for the treatment of symptomatic WON. Previous recommendations stipulated that endoscopic intervention should be delayed until more than four weeks after the onset. Recent data on early drainage have been increasing and this option might be considered in well-encapsulated cases, but the percutaneous route is preferred if the drainage is performed within two weeks after onset or in nonencapsulated cases. Recently, additional drainage methods, such as the multiple gateway technique and multiple stent placement, have been developed to open up multiple dead spaces in the WON cavity. Endoscopic necrosectomy could be performed via the transluminal route or percutaneous route after failed initial and additional drainage procedures. The use of novel lumen-apposing stents is a promising treatment option that could reduce the number of steps, the procedure time, and the overall number of necrosectomies.

Abstract
Severe acute pancreatitis remains a life-threatening condition, responsible for many disorders of homeostasis and organ dysfunction. By means of a mnemonic 'PANCREAS', eight important steps in the management of severe acute pancreatitis are highlighted. These steps follow the principle of goal-directed therapy and should be borne in mind after diagnosis and during clinical treatment. The first step is perfusion: the goal is to reach a central venous pressure of 12-15mmHg, urinary output 0.5-1ml/kg/hour and inferior vena cava collapse index greater than 48%. Next is analgesia: multimodal, systemic and combined pharmacological agent and epidural block are possibilities. Third is nutrition: precocity, enteral feeding in gastric or post-pyloric position. Parenteral nutrition works best in difficult cases to achieve the individual total caloric value. Fourth is clinical: mild, moderate or severe pancreatitis according to the Atlanta criteria. Radiology is fifth: abdominal computed tomography on the fourth day for prognosis or to modify management. Endoscopy is sixth: endoscopic retrograde cholangiopancreatography (cholangitis, unpredicted clinical course and ascending jaundice); management of pancreatic fluid collection and 'walled-off necrosis'. Antibiotics come next: infectious complications are common causes of morbidity. The only rational indication for antibiotics is documented pancreatic infection. The last step is surgery: the dogma is represented by the 'three Ds' (delay, drain, debride). The preferred method is a minimally invasive step-up approach, which allows for gradually more invasive procedures when the previous treatment fails.

Abstract
BACKGROUND Secondary infection is an important factor affecting mortality and quality of life in patients with severe acute pancreatitis. The characteristics of secondary infection, which are well known to clinicians, need to be re-examined in detail, and their understanding among clinicians needs to be updated accordingly. AIM This study aims to investigate the characteristics and drug resistance of pathogens causing severe acute pancreatitis (SAP) secondary infection, to objectively present infection situation, and to provide reference for improved clinical management. METHODS A retrospective analysis was performed on 55 consecutive patients with SAP who developed secondary infection with an accurate evidence of bacterial/fungal culture from 2016 to 2018. The statistics included the spectrum and distribution of pathogens, the drug resistance of main pathogens, and associations between multiple infectious parameters and mortality. RESULTS A total of 181 strains of pathogens were isolated from (peri)pancreas; bloodstream; and respiratory, urinary, and biliary systems in 55 patients. The strains included 98 g-negative bacteria, 58 g-positive bacteria, and 25 fungi. Bloodstream infection (36.5%) was the most frequent infectious complication, followed by (peri)pancreatic infection (32.0%). Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and Stenotrophomonas maltophilia were predominant among gram-negative bacteria. Gram-positive bacterial infections were mainly caused by Enterococcus faecium and Staphylococcus spp. Fungal infections were predominantly caused by Candida spp. The drug resistance of pathogens causing SAP secondary infection was generally higher than the surveillance level. Patients in the death group were older (55 ± 13 years vs. 46 ± 14 years; p = 0.039) and had longer intensive care unit (ICU) stay (14 vs. 8; p = 0.026) than those in the survival group. A. baumannii infection (68.4% vs. 33%; p = 0.013), number of pathogens ≥ 4 (10 vs. 6; p = 0.005), pancreatic infection (14 vs. 15, p = 0.024), and urinary infection (8 vs. 5; p = 0.019) were significantly associated with mortality. CONCLUSION Gram-negative bacteria are the main pathogens causing SAP secondary infection, in which nosocomial infections play a major role. The drug resistance profile of gram-negative bacteria is seriously threatening, and the commonly used antibiotics in SAP are gradually losing their effectiveness. Much attention should be paid to the rational use of antibiotics, and strategies should be established for infection prevention in SAP.

Abstract
BACKGROUND AND AIMS Pancreatic necrosis may be categorized as an acute necrotic collection (ANC) or walled-off necrosis (WON) based on complete encapsulation by a wall and collection age (≤4 weeks or >4 weeks). Endoscopic intervention of WON has become the standard of care, but little is known regarding the safety and efficacy of endoscopic intervention of pancreatic necrosis ≤4 weeks from disease onset. METHODS Retrospective review of medical records and imaging studies of all patients undergoing early endoscopic intervention of pancreatic necrosis between 2008 and 2018 was carried out at 1 referral center. Patients who underwent previous interventional treatment were excluded. Control WON patients were matched to early intervention cases. The primary outcome was defined as resolution of the collection after endoscopic treatment, without surgery. RESULTS Nineteen patients with early intervention were identified. The most common indication for intervention was infection. Median age of these collections at the time of initial endoscopic intervention was 23 days (range, 15-27 days), and all collections had a partial or complete wall discernable on contrast-enhanced CT. Eleven patients underwent concurrent endoscopic necrosectomy. The primary outcome was achieved in all patients in the early intervention group. Total duration of therapy was longer for early intervention compared with controls (103 vs 69 days, P = .042), with no mortality and similar adverse event rates compared with controls. CONCLUSIONS Endoscopic intervention of pancreatic necrosis in the third and fourth weeks of illness appears effective and safe when a partial collection wall is present on cross-sectional imaging studies, with outcomes paralleling those reported for intervention of WON.

Abstract
Pancreatic fluid collections (PFC), including pancreatic pseudocysts and walled-off pancreatic necrosis, are a known complication of severe acute pancreatitis. A majority of the PFCs remain asymptomatic and resolve spontaneously. However, some PFCs persist and can become symptomatic. Persistent PFCs can also cause further complications such as the gastric outlet, intestinal, or biliary obstruction and infection. Surgical interventions are indicated for the drainage of symptomatic sterile and infected PFCs. Management of PFCs has evolved from a primarily surgical or percutaneous approach to a less invasive endoscopic approach. Endoscopic interventions are associated with improved outcomes with lesser chances of complications, faster recovery time, and lower healthcare utilization. Endoscopic ultrasound-guided drainage of PFCs using lumen-apposing metal stents has become the preferred approach for the management of symptomatic and complicated PFCs.

Abstract
INTRODUCTION Detailed recommendations and guidelines for acute pancreatitis (AP) management currently exist. However, quality indicators (QIs) are required to measure performance in health care. The goal of the Acute Pancreatitis Task Force on Quality was to formally develop QIs for the management of patients with known or suspected AP using a modified version of the RAND/UCLA Appropriateness Methodology. METHODS A multidisciplinary expert panel composed of physicians (gastroenterologists, hospitalists, and surgeons) who are acknowledged leaders in their specialties and who represent geographic and practice setting diversity was convened. A literature review was conducted, and a list of proposed QIs was developed. In 3 rounds, panelists reviewed literature, modified QIs, and rated them on the basis of scientific evidence, bias, interpretability, validity, necessity, and proposed performance targets. RESULTS Supporting literature and a list of 71 proposed QIs across 10 AP domains (Diagnosis, Etiology, Initial Assessment and Risk Stratification, etc.) were sent to the expert panel to review and independently rate in round 1 (95% of panelists participated). Based on a round 2 face-to-face discussion of QIs (75% participation), 41 QIs were classified as valid. During round 3 (90% participation), panelists rated the 41 valid QIs for necessity and proposed performance thresholds. The final classification determined that 40 QIs were both valid and necessary. DISCUSSION Hospitals and providers managing patients with known or suspected AP should ensure that patients receive high-quality care and desired outcomes according to current evidence-based best practices. This physician-led initiative formally developed 40 QIs and performance threshold targets for AP management. Validated QIs provide a dependable quantitative framework for health systems to monitor the quality of care provided to patients with known or suspected AP.

Abstract
INTRODUCTION The initial therapeutic intervention for infected necrotizing pancreatitis usually begins with endoscopic cystogastrostomy for drainage, followed by endoscopic necrosectomy. Endoscopic pancreatic necrosectomy is commonly performed transluminally through transgastric or transduodenal routes. This case describes necrosectomy via a transcutaneous route for laterally located walled-off pancreatic necrosis and the novel use of Babcock forceps for an obstructed fully covered metal stent. CASE PRESENTATION A 62-year-old woman presented with abdominal pain, nausea, and vomiting. After multiple admissions and repeated abdominal imaging, she was found to have laterally located, infected, walled-off pancreatic necrosis. Initially, a drainage catheter was placed by an interventional radiologist and was eventually upsized to a 28F catheter. Subsequently, a fully covered metal stent was placed in the gastroenterology suite under fluoroscopic guidance and was used to gain access for percutaneous sessions of necrosectomy. A percutaneous sinus tract endoscopic necrosectomy was performed under direct endoscopic view. However, difficulties occurred with removing necrotic debris even through this large covered stent. Thus, laparoscopic Babcock forceps were used under fluoroscopy to remove lodged debris from the midstent. Repeat abdominal computed tomography scan 3 days after necrosectomy showed near resolution of the walled-off pancreatic necrosis. DISCUSSION This Babcock technique with endoscopic necrosectomy has not been previously described in the literature, to our knowledge. Babcock forceps were an ideal tool in our case because they were able to gain access to the obstruction in the stent, but the "teeth" are small and dull enough to prevent from catching onto the metal stent mesh.

Abstract
Background and study aim Endoscopic treatment of walled-off pancreatic necrosis (WOPN) has been established as an alternative to operative intervention for well selected patients for many years. Patients and methods A retrospective database of patients who underwent cap-assisted endoscopic necrosectomy of symptomatic or infected WOPN using the assistance of a sterilized banding cap was constructed. All procedures were performed at a single center between January 2017 and June 2018. Results Eight patients met the inclusion criteria for this study. Contrast computed tomography scan was obtained between the initial percutaneous or trans-gastric access and initial necrosectomy. The WOPN had a median length of 9.5 cm (range 3.2 - 14) and width of 5.3 cm (range 2.8 - 11.6). Median duration of endoscopic debridement was 69 minutes (range 21 - 105). Four of six patients underwent a second debridement with a median duration of 95 minutes (range 16 - 108). No periprocedural adverse events occurred. Follow-up was at 6 months, and there were no additional endoscopic or percutaneous interventions for recurrent pancreatic fluid collections. Conclusion The technique of cap-assisted necrosectomy can allow for safe and efficient method of endoscopically treating WOPN.

Abstract
PURPOSE Endoscopy is playing an ever-increasing role in the management of acute biliopancreatic disorders. With the management paradigm shifting away from more invasive surgical approaches, surgeons need to be aware of the treatment options available to improve patient care. Our manuscript serves to improve surgeons' knowledge and understanding of these emerging treatment modalities to expand their algorithmic approach to biliopancreatic disorders. METHODS Specific acute biliopancreatic disorders were identified from the literature and personal practice to create a structured review of common problems experienced by a surgeon of the gastrointestinal tract. An exhaustive literature review was performed to identify and analyze endoscopic treatment modalities for these disorders. RESULTS Endoscopic therapies continue to expand rapidly with a robust supportive literature. Data on endoscopic treatment strategies for acute biliopancreatic disorders demonstrate valuable improvements in outcomes in a number of these disorders. DISCUSSION Acute biliopancreatic disorders represent one of the most challenging pathophysiologies that a surgeon of the gastrointestinal tract may face. This manuscript represents a review of available endoscopic instrumentation as well as the author's interpretation of the current literature regarding indications and outcomes of endoscopic management for acute biliopancreatic disorders. Although this article does not supplant formal training in therapeutic endoscopy, surgeons reading this article should understand the role endoscopy plays in the management of acute biliopancreatic disorders.

Abstract
Incidence of acute pancreatitis seems to be increasing in the Western countries and has been associated with significantly increased morbidity. Nearly 80% of the patients with acute pancreatitis undergo resolution; some develop complications including pancreatic necrosis. Infection of pancreatic necrosis is the leading cause of death in these patients. A significant portion of these patients needs surgical interventions. Traditionally, the “gold standard” procedure has been the open surgical necrosectomy, which is now being completed by the relatively lesser invasive interventions. Minimally invasive surgical (MIS) procedures include endoscopic drainage, percutaneous image-guided catheter drainage, and retroperitoneal drainage. This review article discusses the open and MIS interventions for pancreatic necrosis with each having its own respective benefits and disadvantages are covered.

Abstract
Background Infected necrosis complicates 10% of all acute pancreatitis episodes and is associated with 15–20% mortality. The current standard treatment for infected necrotizing pancreatitis is the step-up approach (catheter drainage, followed, if necessary, by minimally invasive necrosectomy). Catheter drainage is preferably postponed until the stage of walled-off necrosis, which usually takes 4 weeks. This delay stems from the time when open necrosectomy was the standard. It is unclear whether such delay is needed for catheter drainage or whether earlier intervention could actually be beneficial in the current step-up approach. The POINTER trial investigates if immediate catheter drainage in patients with infected necrotizing pancreatitis is superior to the current practice of postponed intervention. Methods POINTER is a randomized controlled multicenter superiority trial. All patients with necrotizing pancreatitis are screened for eligibility. In total, 104 adult patients with (suspected) infected necrotizing pancreatitis will be randomized to immediate (within 24 h) catheter drainage or current standard care involving postponed catheter drainage. Necrosectomy, if necessary, is preferably postponed until the stage of walled-off necrosis, in both treatment arms. The primary outcome is the Comprehensive Complication Index (CCI), which covers all complications between randomization and 6-month follow up. Secondary outcomes include mortality, complications, number of (repeat) interventions, hospital and intensive care unit (ICU) lengths of stay, quality-adjusted life years (QALYs) and direct and indirect costs. Standard follow-up is at 3 and 6 months after randomization. Discussion The POINTER trial investigates if immediate catheter drainage in infected necrotizing pancreatitis reduces the composite endpoint of complications, as compared with the current standard treatment strategy involving delay of intervention until the stage of walled-off necrosis.

Abstract
Walled of pancreatic necrosis (WOPN) is a new term coined for encapsulated fluid collection developing after acute necrotising pancreatitis (ANP). It is a heterogeneous collection containing varying amount of liquid as well as solid necrotic material. The literature on its natural history as well as appropriate management is gradually expanding thereby improving treatment outcomes of this enigmatic disease. Areas covered: This review discusses currently available literature on etiology, frequency, natural history, and imaging features WOPN. Also, updated treatment options including endoscopic, radiological and surgical drainage are discussed. Expert opinion: WOPN is alocal complication of ANP occurring in the delayed phase of ANP and may be asymptomatic (50%) or present with pain, fever, jaundice, or gastric outlet obstruction. Natural courses of asymptomatic WOPN have been infrequently studied, and it appears that the majority remain asymptomatic and resolve spontaneously. Magnetic resonance imaging and endoscopic ultrasound are the best imaging modalities to evaluate solid necrotic debris. Symptomatic WOPN usually needs immediate drainage, this can be done endoscopically, radiologically, or surgically. Current evidence suggests that endoscopic transluminal drainage is the preferred drainage technique as it is effective and associated with lower mortality, risk of organ failure, adverse effects, and length of hospital stay.

Abstract
Since the original description of pancreatic fluid collections (PFC) in 1761 by Morgagni, their diagnosis, description, and management have continued to evolve. The mainstay of therapy for symptomatic PFCs has been the creation of a communication between a PFC and the stomach, to enable drainage. Surgical creation of these drainage conduits had been the gold standard of therapy; however, there has been a paradigm shift in recent years with an increasing role of endoscopic drainage. The techniques of endoscopic drainage have evolved from blind fluid aspiration to include endoscopic necrosectomy and the placement of lumen-apposing metal stents.

Abstract
OBJECTIVES This study aimed to assess the need of surgical necrosectomy after percutaneous catheter drainage (PCD) for infected necrotizing pancreatitis. METHODS The clinical data of documented/suspected patients who were treated with a step-up approach were extracted and analyzed. RESULTS Of the 329 patients enrolled, the initial PCD was performed at 12 (interquartile range, 9-15) days since onset and 35.3% were cured by PCD alone. In the pre-PCD model, mean computed tomographic (CT) density of necrotic fluid collection (NFC; P < 0.001), and multiple-organ failure (MOF; P < 0.001) within 24 hours before the initial PCD were independent risk factors, and a combination of the previously mentioned 2 factors produced an area under the curve of 0.775. In the post-PCD model, mean CT density of NFC (P = 0.041), MOF (P = 0.002), and serum procalcitonin level (P = 0.035) 3 days after the initial PCD were independent risk factors, and a combination of these previously mentioned factors produced an area under the curve of 0.642. CONCLUSIONS Both mean CT density of NFC and MOF are independent pre- and post-PCD risk factors for the need of necrosectomy after PCD. Post-PCD serum procalcitonin level might be a respondent factor that is correlated with the necessity of necrosectomy.

Abstract
BACKGROUND Over the past decade, the treatment of necrotizing pancreatitis (NP) has incorporated greater use of minimally invasive techniques, including percutaneous drainage and endoscopic debridement. No study has yet compared outcomes of patients treated with all available techniques. We sought to evaluate the evolution of NP treatment at our high volume pancreas center. We hypothesized that minimally invasive techniques (medical only, percutaneous, and endoscopic) were used more frequently in later years. METHODS Treatment strategy of NP patients at a single academic medical center between 2005 and 2014 was reviewed. Definitive management of pancreatic necrosis was categorized as: 1) medical treatment only; 2) surgical only; 3) percutaneous (interventional radiology - IR) only; 4) endoscopic only; and 5) combination (Surgery ± IR ± Endoscopy). RESULTS 526 NP patients included biliary (45%), alcoholic (17%), and idiopathic (20%) etiology. Select patients were managed exclusively by medical, IR, or endoscopic treatment; use of these therapies remained relatively consistent over time. A combination of therapies was used in about 30% of patients. Over time, the percentage of NP patients managed without operation increased from 28% to 41%. 247 (47%) of patients had operation as the only NP treatment; an additional 143 (27%) required surgery as part of a multidisciplinary management. CONCLUSION Select NP patients may be managed exclusively by medical, IR, or endoscopic treatment. Combination treatment is necessary in many NP patients, and surgical treatment continues to play an important role in the definitive therapy of necrotizing pancreatitis patients.

Abstract
Acute necrotizing pancreatitis is a prevalent disease with high morbidity and mortality. The development of radiologic and endoscopic techniques to manage pancreatic necrosis commands a multidisciplinary approach, which has considerably decreased the need for laparotomy. The objective of this update is to define the role of surgery in the multidisciplinary approach to management of necrotizing acute pancreatitis.

Abstract
AIM To evaluate the short- and long-term results of endoscopic ultrasound-guided transmural drainage (EUS-GTD) for pancreatic fluid collection (PFC) and identify the predictive factors of treatment outcome for walled-off necrosis (WON) managed by EUS-GTD alone.
METHODS We investigated 103 consecutive patients with PFC who underwent EUS-GTD between September 1999 and August 2015. Patients were divided into four groups as follows: WON (n = 40), pancreatic pseudocyst (PPC; n = 11), chronic pseudocyst (n = 33), and others (n = 19). We evaluated the short- and long-term outcomes of the treatment. In cases of WON, multiple logistic regression analyses were performed to identify the predictor variables associated with the treatment success. In addition, PFC recurrence was examined in patients followed up for more than 6 mo and internal stent removal after successful EUS-GTD was confirmed.
RESULTS In this study, the total technical success rate was 96.1%. The treatment success rate of WON, PPC, chronic pseudocyst, and others was 57.5%, 90.9%, 91.0%, and 89.5%, respectively. Contrast-enhanced computed tomography using the multivariate logistic regression analysis revealed that the treatment success rate of WON was significantly lower in patients with more than 50% pancreatic parenchymal necrosis (OR = 17.0; 95%CI: 1.9-150.7; P = 0.011) and in patients with more than 150 mm of PFC (OR = 27.9; 95%CI: 3.4-227.7; P = 0.002).The recurrence of PFC in the long term was 13.3% (median observation time, 38.8 mo). Mean amylase level in the cavity was significantly higher in the recurrence group than in the no recurrence group (P = 0.02).
CONCLUSION The reduction of WON by EUS-GTD alone was associated with the proportion of necrotic tissue and extent of the cavity. The amylase level in the cavity may be a predictive factor for recurrence of PFC.

Abstract
OBJECTIVES The minimally invasive step-up approach for treatment of walled off necrosis (WON) involves drainage followed by later necrosectomy as needed, and is superior to primary surgical necrosectomy. Reported series of endoscopic transluminal necrosectomy include highly selected patients. We report outcomes of a large series of patients with WON managed by an algorithm based on an endoscopically centered step-up approach. METHODS Consecutive patients with necrotizing pancreatitis from 2009 to 2014, with intervention only for infected or persistently symptomatic WON. The primary approach involved endoscopic transluminal drainage plus minus necrosectomy whenever feasible, with percutaneous catheter drainage (PCD) plus minus sinus tract endoscopy if not feasible or sufficient. Surgery was reserved for failures of the step up approach. RESULTS Of 109 consecutive patients with necrotizing pancreatitis, intervention was required in 83, including endoscopic transluminal drainage in 73 (88%) (alone in 49 and combined with PCD in 24), and PCD alone in 10 (12%). 64 (77%) of the 83 patients required endoscopic transluminal and/or sinus tract necrosectomy. Adverse events occurred in 11 (13%). Three patients (4%) failed step up approach and required open surgical necrosectomy. All-cause mortality occurred in 6 (7%) of 83 patients after intervention, including 2 of 3 requiring surgery. CONCLUSIONS An algorithm based step-up approach for interventions in necrotizing pancreatitis using primarily endoscopic techniques with adjunctive percutaneous approaches as needed resulted in favorable outcomes with small numbers proceeding to open surgery, and with acceptable rates of major complications and mortality. A purely endoscopic transluminal approach was feasible in approximately 60% of patients requiring intervention in this series.

Abstract
BACKGROUND Severe acute pancreatitis is a subtype of acute pancreatitis, associated with multiple organ failure and systemic inflammatory response syndrome. In this qualitative review we looked at the principles of pathogenesis, classification and surgical management of severe acute pancreatitis. We also looked at the current shift in paradigm in the management of severe acute pancreatitis since the guideline developed by the British Society of Gastroenterology. DATA SOURCES Studies published between 1st January 1991 and 31st December 2015 were identified with PubMed, MEDLINE, EMBASE and Google Scholar online search engines using the following Medical Subject Headings: "acute pancreatitis, necrosis, mortality, pathogenesis, incidence" and the terms "open necrosectomy and minimally invasive necrosectomy". The National Institute of Clinical Excellence (NICE) Guidelines were also included in our study. Inclusion criteria for our clinical review included established guidelines, randomized controlled trials and non-randomized controlled trials with a follow-up duration of more than 6 weeks. RESULTS The incidence of severe acute pancreatitis within the UK is significantly rising and pathogenetic theories are still controversial. In developed countries, the most common cause is biliary calculi. The British Society of Gastroenterology, acknowledges the Revised Atlanta criteria for prediction of severity. A newer Determinant-based system has been developed. The principle of surgical management of acute necrotizing pancreatitis requires intensive care management, identifying infection and if indicated, debridement of any infected necrotic area. The current procedures opted for include standard surgical open necrosectomy, endoscopic necrosectomy and minimally invasive necrosectomy. The current paradigm is shifting towards a step-up approach. CONCLUSIONS Severe acute pancreatitis is still a subject of grey areas in its surgical management even though new studies have been recorded since the origin of the latest UK guidelines for management of severe acute pancreatitis.

Abstract
Pancreatic fluid collections (PFCs) are a frequent complication of pancreatitis, or less commonly, pancreatic trauma or surgery. The revised Atlanta Classification categorizes PFCs as acute or chronic, with further subclassification of acute collections into acute peripancreatic collections and acute necrotic collections and of chronic fluid collections into pseudocysts and walled-off pancreatic necrosis. Acute PFCs are generally only subjected to an intervention when they are infected and not responding to antibiotics and are not managed endoscopically. Chronic PFCs, both pseudocysts and walled-off pancreatic necrosis, require intervention only when symptomatic or enlarging over time. Endoscopic ultrasound-guided drainage has become the mainstay of management for chronic PFCs that require intervention. Developments in medical devices over the past few years have significantly simplified and shortened the duration of the procedure itself, but the optimum choice of stent in different clinical scenarios remains to be defined, as does the place of endoscopic necrosectomy. To optimize outcomes, these patients should undergo a careful preprocedure workup and discussion in a multidisciplinary environment and procedures should be carried out in high-volume pancreatic units.

Abstract
Severe acute pancreatitis is often complicated by the development of pancreatic fluid collections (PFCs), which may be associated with significant morbidity and mortality. It is crucial to accurately classify these collections as a pseudocyst or walled-off necrosis (WON) given significant differences in outcomes and management. Interventions for PFCs have increasingly shifted to less invasive strategies, with endoscopic ultrasound (EUS)-guided methods being shown to be safer and equally effective as more invasive surgical techniques. In recent years, many new developments have improved the safety and efficacy of EUS-guided interventions, such as the introduction of lumen-apposing metal stents (LAMS), direct endoscopic necrosectomy (DEN) and multiple other adjunctive techniques. Despite these developments, treatment of PFCs, and infected WON in particular, continues to be associated with significant morbidity and mortality. In this article, we discuss the EUS-guided management of PFCs while reviewing the latest developments and controversies in the field. We end by summarizing our own approach to managing PFCs.

Abstract
BACKGROUND A proportion of patients with acute pancreatitis (AP) develop necrosis. Around a third will become infected, and this is associated with a significant requirement for intervention and support. We evaluated the burden of necrotizing pancreatitis (NP) in an Australian tertiary hospital with regards to morbidity, mortality and resource consumption. METHODS This is a retrospective case series of patients with AP admitted for at least 5 days to identify those with NP between 2009 and 2014. Data were analysed in groups according to the determinant-based classification of AP severity. RESULTS Of 1339 patients with AP, 546 stayed 5 days or longer, and 38 had necrosis. Overall mortality for those with necrosis was 10.5% (4/38). Infection complicated necrosis in 45% (17/38). Organ failure also occurred in 45% (17/38) of patients with necrosis. All patients in the critical category and severe category required admission to the intensive care unit for a median of 21 and 12 days, respectively. A total of 90% of patients with critical category disease developed multi-organ failure, whereas most with severe category disease developed single organ failure only. Overall length of stay increased with increasing severity of disease. Intervention was required in 82% of infected necrosis (median 4 procedures). Those without infection also required multiple radiological investigations (median 7). CONCLUSION Necrosis is uncommon in our cohort but is associated with a significant health-care burden. Almost half the patients with necrosis develop organ failure requiring prolonged hospital and intensive care unit stay. Patients require multiple investigations and interventions for infected necrosis. NP remains a costly, morbid disease in our society.

Abstract
Acute pancreatitis is a common disease that can progress to gland necrosis, which imposes significant risk of morbidity and mortality. In general, the treatment for pancreatitis is a supportive therapy. However, there are several reasons to escalate to surgery or another intervention. This review discusses the pathophysiology as well as medical and interventional management of necrotizing pancreatitis. Current evidence suggests that patients are best served by delaying interventions for at least 4 weeks, draining as a first resort, and debriding recalcitrant tissue using minimally invasive techniques to promote or enhance postoperative recovery while reducing wound-related complications.

Abstract
Walled-off necrosis (WON) is a relatively new term for encapsulated necrotic tissue after severe acute pancreatitis. Various terminologies such as pseudocyst, necroma, pancreatic abscess, and infected necrosis were previously used in the literature, resulting in confusion. The current and past terminologies must be reconciled to meaningfully interpret past data. Recently, endoscopic necrosectomy was introduced as a treatment option and is now preferred over surgical necrosectomy when the expertise is available. However, high-quality evidence is still lacking, and there is no standard management strategy for WON. The consensus meeting aimed to clarify the diagnostic criteria for WON and the role of endoscopic interventions in its management. In the Consensus Conference, 27 experts from eight Asian countries took an active role and examined key clinical aspects of WON diagnosis and endoscopic management. Statements were crafted based on literature review and expert opinion, employing the modified Delphi method. All statements were substantiated by the level of evidence and the strength of the recommendation. We created 27 consensus statements for WON diagnosis and management, including details of endoscopic procedures. When there was not enough solid evidence to support the statements, this was clearly acknowledged to facilitate future research. Proposed management strategies were formulated and are illustrated using flow charts. These recommendations, which are based on the best current scientific evidence and expert opinion, will be useful for guiding endoscopic management of WON. Part 1 of this statement focused on the epidemiology, diagnosis, and timing of intervention.
