Abstract
Endoscopic transmural drainage is usually performed for symptomatic well-encapsulated walled-off necrosis (WON) that usually develops in the delayed phase (> 4 weeks after disease onset) of acute necrotising pancreatitis (ANP). Endoscopic drainage is usually not advocated in the early (< 4 weeks after disease onset) stage of illness because of the risk of complications due to an incompletely formed encapsulating wall and poor demarcation of viable from necrotic tissue. However, emerging data from expert tertiary care centres over the last few years shows that the early endoscopic transluminal drainage approach is effective and safe. The development of lumen-apposing metal stents and better accessories for endoscopic necrosectomy has fuelled the expansion of indications of endoscopic drainage of pancreatic necrosis. However, early endoscopic drainage is associated with higher rates of adverse events; therefore, careful patient selection is paramount. This article will review the current indications, techniques and outcomes of early endoscopic transluminal drainage in pancreatic necrotic collections.

A location-based anatomic classification system for acute pancreatic fluid collections: Roadmap for optimal intervention in the step-up era. Surg Open Sci 2024; 18:1-5. [PMID: 38312303 PMCID: PMC10831243 DOI: 10.1016/j.sopen.2024.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 01/02/2024] [Accepted: 01/10/2024] [Indexed: 02/06/2024] Open
Abstract
Walled-off pancreatic necrosis (WOPN) is a local complication of acute necrotizing pancreatitis frequently requiring intervention. Treatment is typically through the coordinated efforts of a multidisciplinary team. Current management guidelines recommend a step-up approach beginning with minimally invasive techniques (percutaneous or transmural endoscopic drainage) followed by escalation to more invasive procedures if needed. Although the step-up approach is an evidence-based treatment paradigm for management of pancreatic fluid collections, it lacks guidance regarding optimal invasive technique selection based on the anatomic characteristics of pancreatic fluid collections. Similarly, existing cross-sectional imaging-based classification systems of pancreatic fluid collections have been used to predict disease severity and prognosis; however, none of these systems are designed to guide intervention. We propose a novel classification system which incorporates anatomic characteristics of pancreatic fluid collections (location and presence of disconnected pancreatic duct) to guide intervention selection and clinical decision making. We believe adoption of this simple classification system will help streamline treatment algorithms and facilitate cross-study comparisons for pancreatic fluid collections.

Abstract
Disconnected pancreatic duct (DPD) is common after acute necrotizing pancreatitis (ANP). Its clinical implications vary according to the course of disease. In the early phase of ANP, parenchymal necrosis along with disruption of pancreatic duct cause acute necrotic collection that evolves into walled-off necrosis (WON). In the later phase, DPD becomes evident as confirmed by magnetic resonance cholangiopancreatography. Clinical manifestations of DPD can vary from being asymptomatic, recurrent pain, recurrent pancreatic fluid collection (PFC), obstructive pancreatitis, or external pancreatic fistula (EPF). Few patients develop new-onset diabetes. Long-term indwelling plastic stents have been proposed to prevent the recurrent PFC.

Abstract
BACKGROUND Necrotizing pancreatitis can be complicated by Necrotic Fluid Collections (NFC). Guidelines recommend waiting for 4 weeks from the onset of acute pancreatitis (AP) before considering endoscopic drainage. We aimed to compare outcomes and safety in patients undergoing early versus late drainage of NFC. METHODS We performed a retrospective review of all patients who underwent Dual Modality Drainage (DMD) [combined endoscopic and percutaneous drainage] for NFC from January 2007 to December 2020. Patients were stratified into the "early" group (DMD < 28 days from AP onset) and were matched to "late" (DMD ≥ 28 days) drainage group using propensity- core-matching. Primary outcomes of interest were technical success and adverse events. Secondary outcomes included clinical success, late complication rates, and mortality. RESULTS We identified 278 patients who underwent DMD for NFC. Thirty-nine belonged to the early group and were matched to 174 patients from the late group. Technical success was similar in both early and late groups (97.4% vs 99.4%: P = 0.244) as were the procedural and early post-procedural (< 14 days) adverse events rates (23.1% vs 27.6%: P = 0.565). Clinical success (92.3% vs 93.1%; P = 0.861) and late complication rates (23.1% vs 31.6%; P = 0.294) were similar. There were 2 deaths (5.7%) in the early vs. 9 (5.2%) in the late group, P = 0.991. CONCLUSIONS When performed in a tertiary care center with expertise in therapeutic endoscopic ultrasound, early drainage of NFC appears to be feasible and safe. Further studies are needed to validate our results.

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
Pancreatic fluid collections often develop as a complication of acute pancreatitis but can be seen in a variety of conditions including chronic pancreatitis, trauma, malignancy or post-operatively. It is important to classify a pancreatic fluid collection in order to optimize treatment strategies and management. Most interventions are targeted towards the management of delayed complications of pancreatitis, including pancreatic pseudocysts and walled-off necrosis (WON), which often develop days to weeks after the initial episode of pancreatitis. Surgical, percutaneous, and endoscopic interventions are all possible methods for treatment of pancreatic fluid collections, however endoscopic drainage with endoscopic ultrasound has become first-line. Advances within endoscopic drainage strategies have also led to innovative changes in the specific stents used for treatment, with possible options including double pigtail plastic stents, fully covered self-expanding metal stents and lumen-apposing metal stents (LAMS).

Abstract
BACKGROUND AND AIMS Traditional management for infected necrotizing pancreatitis (INP) often utilizes open necrosectomy, which carries high morbidity and complication rates. Thus, minimally invasive strategies have gained favor, specifically step-up approaches utilizing endoscopic or minimally-invasive surgery (MIS); however, the ideal management modality for INP has not been identified. METHODS A decision tree model was designed to analyze costs and survival associated with open necrosectomy, endoscopic step-up, and MIS step-up protocols for management of INP after 4 weeks of necrosis development with adequate retroperitoneal access. Costs were based on a third-party payer perspective using Medicare reimbursement rates. The model's effectiveness was represented by quality-adjusted life-years (QALYs). Sensitivity analyses were performed to validate results. RESULTS Endoscopic step-up was the dominant economic strategy with 7.92 QALYs for $90,864.09. Surgical step-up resulted in a decrease of 0.09 QALYs and a cost increase of $10,067.89 while open necrosectomy resulted in a decrease of 0.4 QALYs and an increased cost of $18,407.52 over endoscopic step-up. In 100,000 random-sampling simulations, 65.5% of simulations favored endoscopic step-up. MIS step-up was favored when MIS acute mortality rates fell and when MIS drainage success rates rose. CONCLUSIONS In our simulated patients with INP, the most cost-effective management strategy is endoscopic step-up. Cost-effectiveness varies with changes in acute mortality and drainage success, which will depend on local expertise.

Abstract
OBJECTIVES The Pancreatitis Activity Scoring System (PASS) is an objective tool validated in acute pancreatitis but not in infected pancreatic necrosis (IPN). Our aim was to evaluate the role of PASS in IPN. METHODS We performed a retrospective cohort study of IPN patients admitted to the University of California, San Francisco from January 2011 to March 2019. Daily PASS scores were calculated for each patient. Receiver operator characteristic analysis was used to define the optimal cutoff PASS score to predict outcomes. The primary and secondary outcomes were 72 hours postintervention multiorgan failure (MOF) and early readmission (within 30 days), respectively. RESULTS One hundred and four patients underwent intervention (median age, 55 years). Thirty-five patients (33.6%) developed MOF postintervention. A 72-hour postintervention PASS greater than 250 was strongly associated with postintervention MOF (area under curve, 0.87; adjusted odds ratio, 26.83; 95% confidence interval, 6.37-112.86; P < 0.001). Discharge PASS greater than 150 was associated with 30-day readmission (area under curve, 0.82; adjusted odds ratio, 26.44; 95% confidence interval, 8.48-82.43; P < 0.001). CONCLUSIONS The PASS score was associated with postintervention clinical outcomes and early readmission, suggesting it is a valid measure of disease activity in patients with IPN. Further prospective validation of PASS in IPN is needed.

Abstract
INTRODUCTION A step-up endoscopic or percutaneous approach improves outcomes in necrotizing pancreatitis (NP). However, these require multiple radiographic studies and fluoroscopic procedures, which use low-dose ionizing radiation. The cumulative radiation exposure for treatment of NP has not been well defined. METHODS We conducted a retrospective study of consecutive patients with NP admitted to University of California San Francisco Medical Center from January 2011 to June 2019. We calculated effective doses for fluoroscopic procedures using the dose area product and used the National Cancer Institute tool for computed tomography studies. The primary outcome was the cumulative effective dose (CED). Multivariable logistic regression was used to evaluate risk factors of high exposure (CED > 500 mSv). RESULTS One hundred seventy-one patients with NP (mean follow-up 40 ± 18 months) underwent a median of 7 (interquartile range [IQR] 5-11) computed tomography scans and 7 (IQR 5-12) fluoroscopic procedures. The median CED was 274 mSv (IQR 177-245) and 30% (51) of patients received high exposure. Risk factors of high exposure include multiorgan failure (aOR 3.47, 95%-CI: 1.53-9.88, P = 0.003), infected necrosis (adjusted odds ratio [aOR] 3.89 95%-CI:1.53-9.88, P = 0.005), and step-up endoscopic approach (aOR 1.86, 95%-CI: 1.41-1.84, P = 0.001) when compared with step-up percutaneous approach. DISCUSSION Patients with NP were exposed to a substantial amount of ionizing radiation (257 mSv) as a part of their treatment, and 30% received more than 500 mSv, which corresponds with a 5% increase in lifetime cancer risk. Severity of NP and a step-up endoscopic approach were associated with CED > 500 mSv. Further studies are needed to help develop low-radiation treatment protocols for NP, particularly in patients receiving endoscopic therapy.

Abstract
In addition to acute injury requiring interventional radiologic treatments, patients with traumatic injuries can develop delayed or chronic complications. These injuries can involve nearly all solid organs in the abdomen. Coupled with significant improvements in visualizing these injuries with advanced imaging techniques such as minimally invasive procedures, nonoperative management of both acute traumatic injuries and their longer term sequelae has become the norm. This article reviews frequently seen complications of traumatic injury and their management by interventional radiologists.

Abstract
BACKGROUND Disconnected pancreatic duct syndrome (DPDS) is a complication of acute necrotizing pancreatitis in the neck and body of the pancreas often manifesting as persistent pancreatic fluid collection (PFC) or external pancreatic fistula (EPF). This systematic review and pairwise meta-analysis aimed to review the definitions, clinical presentation, intervention, and outcomes for DPDS. METHODS The PubMed, EMBASE, MEDLINE, and SCOPUS databases were systematically searched until February 2020 using the PRISMA framework. A meta-analysis was performed to assess the success rates of endoscopic and surgical interventions for the treatment of DPDS. Success of DPDS treatment was defined as long-term resolution of symptoms without recurrence of PFC, EPF, or pancreatic ascites. RESULTS Thirty studies were included in the quantitative analysis comprising 1355 patients. Acute pancreatitis was the most common etiology (95.3%, 936/982), followed by chronic pancreatitis (3.1%, 30/982). DPDS commonly presented with PFC (83.2%, 948/1140) and EPF (13.4%, 153/1140). There was significant heterogeneity in the definition of DPDS in the literature. Weighted success rate of endoscopic transmural drainage (90.6%, 95%-CI 81.0-95.6%) was significantly higher than transpapillary drainage (58.5%, 95%-CI 36.7-77.4). Pairwise meta-analysis showed comparable success rates between endoscopic and surgical intervention, which were 82% (weighted 95%-CI 68.6-90.5) and 87.4% (95%-CI 81.2-91.8), respectively (P = 0.389). CONCLUSIONS Endoscopic transmural drainage was superior to transpapillary drainage for the management of DPDS. Endoscopic and surgical interventions had comparable success rates. The significant variability in the definitions and treatment strategies for DPDS warrant standardisation for further research.

Abstract
Objective: To analyze the management of severe necrotizing pancreatitis in a specialized center of a lower middle-income country, Pakistan using multiple outcome measures. Methods: All the patients in this prospective observational study with severe necrotizing pancreatitis being referred to Pak Emirates Military Hospital from January 2017 to December 2019 were followed over the course of their admission. Demographic data and disease outcomes were duly noted. Cox regression analysis was used to predict fatality outcome. Results: A total of 57 patients with 48 (84.6%) infected necrotizing pancreatitis were managed in our set up. The most common etiology reported was gall-stones (37%) with male preponderance (72%) and a mean age of 50±11.3 years. The most common complications were acute-kidney-injury (63%), splenic-vein-thrombosis (21%) and ascites (21%). Fourteen patients required mechanical-ventilation with a mean duration of 7±1.4 days on respiratory support. Eight (14%) patients required Endoscopic-Ultra-Sound guided drainage and six (10.5%) underwent surgical-necrosectomy depending upon the patients’ condition and collections characteristics. Mortality, as one of the main outcome measures, was reported to be 12.3% and was statistically related to mechanical-ventilation, organ failure and surgical-necrosectomy while 22 (38.6%) patients were discharged on pancreatic enzymes supplements and 7% required insulin. Conclusion: Survival outcomes with acute severe necrotizing pancreatitis are improving in a dedicated hepato-biliary unit internationally in lieu with a multidisciplinary team approach. Percutaneous and EUS guided drainage of pancreatic collections have turned out to be an important procedure to manage infected pancreatic necrosis that helps to avoid a morbid procedure in the form of necrosectomy.

Abstract
Pancreatic necrosis is among the most frequently encountered local complications of acute pancreatitis and associates with severe disease. Infected pancreatic necrosis further enhances the risk for morbidity and mortality. Pancreatic fluid collections that result from pancreatic necrosis evolve from acute necrotic collections to walled off necrosis and are defined by their distinct characteristics on cross sectional imaging. A variety of interventions spanning multiple disciplines are available for the drainage and debridement of pancreatic necrosis. Prospective, randomized trials have identified management strategies that incorporate minimally invasive interventions as having the best outcomes for patients with symptomatic pancreatic necrosis. The scientific literature has confidently positioned endoscopic drainage and necrosectomy among the most effective interventions for patients with symptomatic walled off necrosis. Innovations such as the use of metallic stents, chemical debridement and multiple modalities for drainage of pancreatic necrosis show promise in improving outcomes for patients managed with endoscopic interventions.

Abstract
Acute pancreatitis is an unpredictable and potentially lethal disease. The prognosis mainly depends on the development of organ failure and secondary infection of pancreatic or peripancreatic necrosis. In the past 10 years, treatment of acute pancreatitis has moved towards a multidisciplinary, tailored, and minimally invasive approach. Despite improvements in treatment and critical care, severe acute pancreatitis is still associated with high mortality rates. In this Seminar, we outline the latest evidence on diagnostic and therapeutic strategies for acute pancreatitis.

Abstract
Endoscopic cystogastrostomy for mature pancreatic collections has long been recognized. However, FDA approval of newer lumen-apposing metallic stents in 2014 has now brought pancreatic necrosectomy to the endoscopic realm. Endoscopic drainage of Walled-off necrosis and direct endoscopic necrosectomy are technically challenging procedures with higher rates of complications. Collaborative clinical decision making both pre- and post-procedurally between the radiologist, endoscopist, and the surgeon can greatly improve outcomes in necrotizing pancreatitis. Herein, we review the basic pathophysiology that underlies progressive radiographic findings in NP, value of preprocedural imaging, current management algorithms, newer tools, and techniques as well as potential post-procedure complications on imaging follow-up after endoscopic interventions in necrotizing pancreatitis.

Abstract
Background/Aims Acute pancreatitis complicated by walled-off necrosis (WON) is associated with high morbidity and mortality, and if infected, typically necessitates intervention. Clinical outcomes of infected WON have been described as poorer than those of symptomatic sterile WON. With the evolution of minimally invasive therapy, we sought to compare outcomes of infected to symptomatic sterile WON. Methods We performed a retrospective cohort study examining patients who were undergoing dual-modality drainage as minimally invasive therapy for WON at a high-volume tertiary pancreatic center. The main outcome measures included mortality with a drain in place, length of hospital stay, admission to intensive care unit, and development of pancreatic fistulae. Results Of the 211 patients in our analysis, 98 had infected WON. The overall mortality rate was 2.4%. Patients with infected WON trended toward higher mortality although not statistically significant (4.1% vs 0.9%, p=0.19). Patients with infected WON had longer length of hospitalization (29.8 days vs 17.3 days, p<0.01), and developed more spontaneous pancreatic fistulae (23.5% vs 7.8%, p<0.01). Multivariate analysis showed that infected WON was associated with higher odds of spontaneous pancreatic fistula formation (odds ratio, 2.65; 95% confidence interval, 1.20 to 5.85). Conclusions This study confirms that infected WON has worse outcomes than sterile WON but also demonstrates that WON, once considered a significant cause of death, can be treated with good outcomes using minimally invasive therapy.

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
PURPOSE OF REVIEW Endoscopic management of infected necrotizing pancreatitis has evolved rapidly over the past years and there have been interesting innovations in this field. This review provides an update on the most recently published literature regarding endoscopic management of infected necrotizing pancreatitis. RECENT FINDINGS A recent randomized trial demonstrated no difference in mortality and major morbidity between endoscopic and surgical step-up treatment of infected necrotizing pancreatitis. However, endoscopic therapy resulted in shorter hospital stay and less pancreatic fistulas. Various innovations have been investigated with the aim to further optimize endoscopic therapy, in particular lumen-apposing metal stents. While major stent-related complications were also reported, findings from recent studies indicated that their use was associated with higher resolution rates of walled-off necrosis compared to double-pigtail stents. Other innovations, such as the multiple gateway technique and dual-modality mode, can be considered for treatment of particular cases. Furthermore, research suggests that irrigation of walled-off necrosis can be performed by using a nasocystic tube and discontinuation of proton-pump inhibitors may be considered. Endoscopic treatment should be the preferred treatment modality in patients with infected necrotizing pancreatitis who are eligible for endoscopic drainage. Although data suggests that lumen-apposing metal stents are superior to double-pigtail stents, prospective multicenter studies focusing on safety as well as long-term follow-up are first needed.

Abstract
Background Endotherapy is a common method of treatment in patients with symptomatic walled-off pancreatic necrosis (WOPN). The aim of this study is to indicate the potential therapeutic possibilities created by the combination of several new endoscopic techniques and the evaluation of their efficacy in the treatment of WOPN. Methods The retrospective analysis of results and complications in the group of 101 patients, who underwent endoscopic treatment of symptomatic WOPN between years 2011 and 2015. Results Endoscopic treatment was started in 101 patients (71 men, 30 women; mean age 50.97 years) with symptomatic WOPN. Single transluminal gateway technique (SGT) was used in 93/101 (92.08%) patients. SGT in combination with multiple transluminal gateway technique (MTGT) was exploited in 4/93 (4.30%) patients, while in combination with single transluminal gateway transcystic multiple drainage (SGTMD) in 22/93 (23.66%) patients. Transpapillary access was used in 11/101 (10.89%) patients. 20/101 (19.80%) patients underwent percutaneous drainage. Fluoroscopy-guided endoscopic necrosectomy was performed in 19/101 (18.81%) patients. The combinations of endoscopic techniques depended on the extent of necrosis. Procedure-related complications occurred in 16/101 (15.84%) patients. The mortality rate was 0.99% (1/101 patient). Therapeutic success was achieved in 99/101 (98.02%) patients. The long-term success of endoscopic treatment was achieved in 97/101 (96.04%) patients with symptomatic WOPN. Conclusions Application of new endoscopic techniques in the treatment of the patients with symptomatic WOPN significantly improves the efficiency of endotherapy with an acceptable amount of complications.

Abstract
Introduction In last three decades we have been observing development of minimally invasive walled-off pancreatic necrosis (WOPN) treatment techniques. The choice of access to the necrosis and technique of treatment depends not only on the position and spread of necrosis, but in the first place on the experience of the medical center. Aim To assess the effectiveness and safety of combined endoscopic and percutaneous drainage of WOPN. Material and methods We performed a retrospective analysis of 64 consecutive patients with symptomatic WOPN, who underwent endoscopic treatment in our department between 2011 and 2013. Results Additional percutaneous drainage was executed during endoscopic treatment in 20/64 (31.25%) patients. Complications of treatment occurred in 4/20 (20%) patients. Complications of treatment occurred in 4/20 (20%) patients. All these complications were related to endoscopic treatment. No complications related to percutaneous drainage were noted. There were no deaths. Therapeutic success was achieved in all 20 patients. No patients required surgery. The average time of endoscopic drainage was 41.4 (11–173) days. The mean number of endoscopic procedures was 4.2 (2–12). The average time of percutaneous drainage was 11.3 (5–20) days. The medium time of follow-up was 54 (48–64) months. During the observation the recurrence of WOPN was noted in 2/20 (10%) patients. Long-term success of combined drainage was achieved in 18/20 (90%) patients. Conclusions In selected patients with symptomatic WOPN combined endoscopic and percutaneous drainage enables a high success rate with a low procedure-related complication rate.

Abstract
In recent years, the management of symptoms of pancreatic fluid collections has shifted from surgical and percutaneous interventions to endoscopic techniques. Available data show that endoscopic drainage can be achieved with minimal morbidity and procedural-related mortality, a high degree of technical and clinical success, and acceptable risk of adverse events. Although endoscopic management of walled-off necrosis provides a durable, minimally invasive treatment option, it is still generally performed only in tertiary care medical centers because of the overall complexity of this clinical scenario.

Abstract
BACKGROUND Pancreatic or peripancreatic tissue necrosis confers substantial morbidity and mortality. New modalities have created a wide variation in approaches and timing of interventions for necrotizing pancreatitis. As acute care surgery evolves, its practitioners are increasingly being called upon to manage these complex patients. METHODS A systematic review of the MEDLINE database using PubMed was performed. English language articles regarding pancreatic necrosis from 1980 to 2014 were included. Letters to the editor, case reports, book chapters, and review articles were excluded. Topics of investigation included operative timing, the use of adjuvant therapy and the type of operative repair. Grading of Recommendations, Assessment, Development and Evaluations methodology was applied to question development, outcome prioritization, evidence quality assessments, and recommendation creation. RESULTS Eighty-eight studies were included and underwent full review. Increasing the time to surgical intervention had an improved outcome in each of the periods evaluated (72 hours, 12-14 days, 30 days) with a significant improvement in outcomes if surgery was delayed 30 days. The use of percutaneous and endoscopic procedures was shown to postpone surgery and potentially be definitive. The use of minimally invasive surgery for debridement and drainage has been shown to be safe and associated with reduced morbidity and mortality. CONCLUSION Acute Care Surgeons are uniquely trained to care for those with pancreatic necrosis due their training in critical care and complex surgery with ongoing shock. In adult patients with pancreatic necrosis, we recommend that pancreatic necrosectomy be delayed until at least day 12. During the first 30 days of symptoms with infected necrotic collections, we conditionally recommend surgical debridement only if the patients fail to improve after radiologic or endoscopic drainage. Finally, even with documented infected necrosis, we recommend that patients undergo a step-up approach to surgical intervention as the preferred surgical approach.

Abstract
The development of minimally invasive techniques allowed access to the necrotic cavity through transperitoneal, retroperitoneal, transmural and transpapillary routes. The choice of access to walled-off pancreatic necrosis (WOPN) should depend not only on the spread of necrosis, but also on the experience of the clinical center. Herein we describe treatment of a patient with multilocular symptomatic walled-off pancreatic necrosis using minimally invasive techniques. The single transmural access (single transluminal gateway technique - SGT) to the necrotic collection of the patient was ineffective. The second gastrocystostomy was performed using the same minimally invasive technique as an extra way of access to the necrosis (multiple transluminal gateway technique - MTGT). In the described case the performance of the new technique consisting in endoscopic multiplexing transmural access (MTGT) was effective enough and led to complete recovery of the patient.

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
OPINION STATEMENT A disconnected pancreatic duct most commonly follows an episode of severe pancreatitis and walled-off necrosis (WON). When the latter is drained percutaneously, a pancreatic fistula connected to an upstream and disconnected duct is commonly seen. Transgastric drainage of WON with or without concomitant percutaneous drainage (dual drainage) will allow placement of two pigtail stents to drain the upstream duct and ultimately allows removal of percutaneous tubes and avoids the need for distal pancreatectomy. These stents should be left in place indefinitely. In patients referred with percutaneous drains and a disconnected pancreatic duct but without a concomitant fluid collection, a combined procedure, in which an interventional radiologist places a TIPS needle into the drain tract to puncture the stomach, allows the endoscopist access to dilate and stent the tract in a manner comparable to pseudocyst drainage. These stents should be left indefinitely, unless subsequent imaging demonstrates atrophy of the disconnected pancreatic tail.

Abstract
Severe acute pancreatitis (SAP) is an acute abdominal disease which has a number of complications and a high mortality rate. The prognosis had improved much since the use of multidisciplinary comprehensive therapy and minimally invasive treatment in this disease. Percutaneous catheter drainage (PCD) can be used as a step-up minimally invasive treatment for SAP, and as a bridge between internal conservative therapy and open surgery for removal of necrotic tissue. PCD has a therapeutic effect on the local complications of SAP, such as abdominal free effusion, retroperitoneal necrosis infection and pancreatic pseudocyst, and can help to choose the operation timing when the necrotic tissue encapsulation is confirmed in patients with SAP. Clinical therapy should be slected based on the lesion location, quantity and consistency of effusion. When the effusion is located in shallow location, PCD shuold be guided by ultrasound; if the effusion is located in location deep, CT guidance should be adopted. After PCD is finished, the catheter should be cared carefully by keeping the drainage tube patent, rinsing the tube and adjusting its position in time. All of these are the necessary measures to maintain the PCD effectively. When the drainage fluid is less than 10 mL/d and imaging shows that the lesions disappear, it is the best time to remove the tube.

Abstract
Background and Objectives: Development of symptomatic pseudocysts after acute pancreatitis is a common occurrence. Endoscopic ultrasound (EUS)-guided transmural drainage has become the treatment of choice for symptomatic pseudocysts. Following this procedure, stent migration can occur. A recently developed fully covered biliary metal stent with antimigration system has shown promise as an alternative endoprosthetic option for cystogastrostomy. The aim of this study is to describe the success and complications of using covered metal stents with antimigration system to drain pseudocysts at a single tertiary care center. Materials and Methods: The patients undergoing cystogastrostomy using the biliary metal stent with antimigration system over the course of a 10-month period (January-November, 2014) were retrospectively reviewed and all the pertinent information including length of the follow-up, age and sex of the patient, pseudocyst size, pseudocyst size at follow-up, and symptom improvement were recorded. Results: Five patients underwent endoscopic cystogastrostomy using a biliary metal stent with antimigration system. The average age of the patients was 57 years, with all the patients being males. The average size of the largest dimension of pseudocyst was 9 cm. The average follow-up time to repeat imaging was 30 days. All the patients had a significant improvement in their pseudocyst size, with two patients having complete resolution, one patient with a residual 2 cm cyst, and another with a residual 5 cm pseudocyst at follow-up. The average size at follow-up was 2 cm. No complications occurred during the follow-up period. No episodes of stent migration occurred. All the patients had symptom improvement at follow-up. Conclusion: Using a novel biliary covered self-expandable metal stent with antimigration system with EUS guidance to drain pseudocysts appears to be a safe and effective procedure in certain settings. Our experience shows rapid cyst resolution with no complications and no stent migration. This stent gives the providers another option when performing cystogastrostomy.

Abstract
This Position Paper contains clinically oriented guidelines by the Italian Association for the Study of the Pancreas (AISP) for the diagnosis and treatment of severe acute pancreatitis. The statements were formulated by three working groups of experts who searched and analysed the most recent literature; a consensus process was then performed using a modified Delphi procedure. The statements provide recommendations on the most appropriate definition of the complications of severe acute pancreatitis, the diagnostic approach and the timing of conservative as well as interventional endoscopic, radiological and surgical treatments.

Abstract
A pancreatic pseudocyst (PPC) is typically a complication of acute and chronic pancreatitis, trauma or pancreatic duct obstruction. The diagnosis of PPC can be made if an acute fluid collection persists for 4 to 6 wk and is enveloped by a distinct wall. Most PPCs regress spontaneously and require no treatment, whereas some may persist and progress until complications occur. The decision whether to treat a patient who has a PPC, as well as when and with what treatment modalities, is a difficult one. PPCs can be treated with a variety of methods: percutaneous catheter drainage (PCD), endoscopic transpapillary or transmural drainage, laparoscopic surgery, or open pseudocystoenterostomy. The recent trend in the management of symptomatic PPC has moved toward less invasive approaches such as endoscopic- and image-guided PCD. The endoscopic approach is suitable because most PPCs lie adjacent to the stomach. The major advantage of the endoscopic approach is that it creates a permanent pseudocysto-gastric track with no spillage of pancreatic enzymes. However, given the drainage problems, the monitoring, catheter manipulation and the analysis of cystic content are very difficult or impossible to perform endoscopically, unlike in the PCD approach. Several conditions must be met to achieve the complete obliteration of the cyst cavity.
Pancreatic duct anatomy is an important factor in the prognosis of the treatment outcome, and the recovery of disrupted pancreatic ducts is the main prognostic factor for successful treatment of PPC, regardless of the treatment method used. In this article, we review and evaluate the minimally invasive approaches in the management of PPCs.

Abstract
AIM To present a novel, less-invasive method of endoscopic drainage (ED) for walled-off pancreatic necrosis (WON).We describe the feasibility, success rate, and complications of combined ED extra-cavitary lavage and debridement of WON using a biliary catheter and high-flow water jet system (water pump). PATIENTS AND METHODS Endoscopic ultrasound (EUS)-guided drainage was performed with insertion of two 7-Fr, 4-cm double pigtail stents. Subsequently a fully covered self-expanding metal stent (fcSEMS) was placed. The key aspect of the debridement was the insertion of a 5-Fr biliary catheter through or along the fcSEMS into the cavity, with ensuing saline lavage using a high-flow water jet system. The patients were then brought back for repeated, planned endoscopic lavages of the WON. No endoscopic intra-cavitary exploration was performed. RESULTS A total of 17 patients (15 men, 2 women; mean age 52.6, range 24 - 69; mean American Society of Anesthesiologists [ASA] score of 3) underwent ED of WON with this new method. The mean initial WON diameter was 9.5 cm, range 8 to 26 cm. The total number of ED was 84, range 2 to 13. The mean stenting period was 42.5 days. The mean follow-up was 51 days, range 3 to 370. A resolution of the WON was achieved in 14 patients (82.3 %). There were no major complications associated with this method. CONCLUSION ED of complex WON with fcSEMS followed by repeated endoscopic extra-cavitary lavage and debridement using a biliary catheter and high-flow water jet system is a minimally invasive, feasible method with high technical and clinical success and minimal complications.

Abstract
BACKGROUND Recently, several endoscopists have described the usefulness of the endoscopic ultrasonography (EUS)-guided, single transluminal gateway technique (SGT) using transmural placement of single or multiple plastic stents or metal stents for a pancreatic pseudocyst (PC) and walled-off necrosis (WON). Moreover, the uses of the multiple transluminal gateway technique (MTGT) and single transluminal gateway transcystic multiple drainages (SGTMD) for complicated pancreatic walled-off necrosis have recently been reported. The aim of this study is to evaluate retrospectively the feasibility and efficacy of endotherapy for the treatment of complicated PC and WON cases. METHODS Eighty-nine patients with a PC (n = 14) and WON (n = 75) were treated under EUS guidance. RESULTS In a total of 89 cases using SGT in combination with MTGT or SGTMD, the present study showed a technical success rate of 100 %, a final clinical success rate of 97.8 %, an adverse event during procedure rate of 0 %, an early adverse event rate of 12.4 %, and a mortality rate of 2.2 %. CONCLUSIONS Even complicated WON cases can be treated using combination endotherapies, although a surgical approach as well as a percutaneous approach should be considered in the cases refractory to endoscopic therapies.

Abstract
Over the last several years, there have been refinements in the understanding and nomenclature regarding the natural history of acute pancreatitis. Patients with acute pancreatitis frequently develop acute pancreatic collections that, over time, may evolve into pancreatic pseudocysts or walled-off necrosis. Endoscopic management of these local complications of acute pancreatitis continues to evolve. Treatment strategies range from simple drainage of liquefied contents to repeated direct endoscopic necrosectomy of a complex necrotic collection. In patients with chronic pancreatitis, pancreatic pseudocysts may arise as a consequence of pancreatic ductal obstruction that then leads to pancreatic ductal disruption. In this review, we focus on the indications, techniques and outcomes for endoscopic therapy of pancreatic pseudocysts and walled-off necrosis.

Abstract
In the last decades, the treatment of pancreatic pseudocysts and necrosis occurring in the clinical context of acute and chronic pancreatitis has shifted towards minimally invasive endoscopic interventions. Surgical procedures can be avoided in many cases by using endoscopically placed, Endoscopic ultrasonography-guided techniques and drainages. Endoscopic ultrasound enables the placement of transmural plastic and metal stents or nasocystic tubes for the drainage of peripancreatic fluid collections. The development of self-expanding metal stents and exchange free delivering systems have simplified the drainage of pancreatic fluid collections. This review will discuss available therapeutic techniques and new developments.

Abstract
BACKGROUND The aim of the study was to compare the outcomes of patients with pancreatic or peripancreatic walled-off necrosis by endoscopy using the conventional approach versus an algorithmic approach based on the collection size, location and stepwise response to intervention. METHODS This was an observational before-after study of consecutive patients managed over two time intervals. In the initial period (2004-2009) symptomatic patients with walled-off necrosis underwent conventional single transmural drainage with placement of two stents and a nasocystic catheter, followed by direct endoscopic necrosectomy, if required. In the later period (2010-2013) an algorithmic approach was adopted based on size and extent of the walled-off necrosis and stepwise response to intervention. The main outcome was treatment success, defined as a reduction in walled-off necrosis size to 2 cm or less on CT after 8 weeks. RESULTS Forty-seven patients were treated in the first interval and 53 in the second. There was no difference in patient demographics, clinical or walled-off necrosis characteristics and laboratory parameters between the groups, apart from a higher proportion of women and Caucasians in the later period. The treatment success rate was higher for the algorithmic approach compared with conventional treatment (91 versus 60 per cent respectively; P < 0·001). On multivariable logistic regression, management based on the algorithm was the only predictor of treatment success (odds ratio 6·51, 95 per cent c.i. 2·19 to 19·37; P = 0·001). CONCLUSION An algorithmic approach to pancreatic and peripancreatic walled-off necrosis, based on the collection size, location and stepwise response to intervention, resulted in an improved rate of treatment success compared with conventional endoscopic management.

Abstract
Severe acute pancreatitis (SAP), which is the most serious type of this disorder, is associated with high morbidity and mortality. SAP runs a biphasic course. During the first 1-2 wk, a pro-inflammatory response results in systemic inflammatory response syndrome (SIRS). If the SIRS is severe, it can lead to early multisystem organ failure (MOF). After the first 1-2 wk, a transition from a pro-inflammatory response to an anti-inflammatory response occurs; during this transition, the patient is at risk for intestinal flora translocation and the development of secondary infection of the necrotic tissue, which can result in sepsis and late MOF. Many recommendations have been made regarding SAP management and its complications. However, despite the reduction in overall mortality in the last decade, SAP is still associated with high mortality. In the majority of cases, sterile necrosis should be managed conservatively, whereas in infected necrotizing pancreatitis, the infected non-vital solid tissue should be removed to control the sepsis. Intervention should be delayed for as long as possible to allow better demarcation and liquefaction of the necrosis. Currently, the step-up approach (delay, drain, and debride) may be considered as the reference standard intervention for this disorder.

Abstract
Interventions for necrotizing pancreatitis have undergone a paradigm shift away from open surgical necrosectomy and toward minimally invasive techniques, with endoscopic transmural drainage (ETD) and necrosectomy emerging as principle forms of treatment. Recent multicenter studies, randomized trials, evidence-based guidelines, and consensus statements have endorsed the safety and efficacy of endoscopic and other minimally invasive techniques for the treatment of walled-off necrosis. A comprehensive review of indications, standard and novel approaches, outcomes, complications, and controversies regarding ETD and necrosectomy is presented. Given the inherent challenges and associated risks, endoscopic techniques for the management of necrotizing pancreatitis should be performed at specialized multidisciplinary centers by expert endoscopists well versed in the management of necrotizing pancreatitis.

Abstract
Pancreatic duct leaks can occur as a result of both acute and chronic pancreatitis or in the setting of pancreatic trauma. Manifestations of leaks include pseudocysts, pancreatic ascites, high amylase pleural effusions, disconnected duct syndrome, and internal and external pancreatic fistulas. Patient presentations are highly variable and range from asymptomatic pancreatic cysts to patients with severe abdominal pain and sepsis from infected fluid collections. The diagnosis can often be made by high-quality cross-sectional imaging or during endoscopic retrograde cholangiopancreatography (ERCP). Because of their complexity, pancreatic leak patients are best managed by a multidisciplinary team comprised of therapeutic endoscopists, interventional radiologists, and surgeons in the field of pancreatic interventions. Minor leaks will often resolve with conservative management while severe leaks will frequently require interventions. Endoscopic treatments for pancreatic duct leaks have replaced surgical interventions in many situations. Interventional radiologists also have the ability to offer therapeutic interventions for many leak patients. The mainstay of endotherapy for pancreatic leaks is transpapillary pancreatic duct stenting with a stent that bridges the leak if possible, but varies based on the manifestation and clinical presentation. Fluid collections that result from leaks, such as pseudocysts, can often be treated by endoscopic transluminal drainage with or without endoscopic ultrasound or by percutaneous drainage. Endoscopic interventions have been shown to be effective and have an acceptable complication rate.

Abstract
BACKGROUND Management options for symptomatic and infected walled-off pancreatic necrosis (WOPN) have evolved over the past decade from open surgical necrosectomy to more minimally invasive approaches. We reported the use of a combined percutaneous and endoscopic approach (dual modality drainage [DMD]) for the treatment of symptomatic and infected WOPN, with good short-term outcomes in a small cohort of patients. OBJECTIVE To describe the long-term outcomes of 117 patients with symptomatic and infected WOPN treated by DMD. DESIGN Review of a prospective, internal review board-approved database. SETTING Single, North American, tertiary-care center. PATIENTS All patients with symptomatic and infected WOPN treated by DMD at our institution between 2007 and 2012. INTERVENTION DMD of symptomatic and infected WOPN. MAIN OUTCOME MEASUREMENTS Disease-related mortality, pancreaticocutaneous fistula formation, need for early and late surgical intervention, procedure-related adverse events. RESULTS A total of 117 patients underwent DMD for symptomatic and infected WOPN. A total of 103 have completed treatment, with all percutaneous drains removed. Ten patients are still undergoing treatment, and 4 patients died with percutaneous drains in place (3.4% disease-related mortality). For the patients completing therapy, the median duration of follow-up was 749.5 days. No patients required surgical necrosectomy or surgical treatment of DMD-related adverse events; 3 patients required late surgery for pain (n = 2) and gastric outlet obstruction (n = 1). There were no procedure-related deaths. In patients who have completed treatment, percutaneous drains have been removed in 100%; no patients have developed pancreaticocutaneous fistulas. LIMITATIONS Single-center design, lack of a comparison group. CONCLUSION DMD for symptomatic and infected WOPN results in favorable clinical outcomes; complete avoidance of pancreaticocutaneous fistulae, surgical necrosectomy, and major procedure-related adverse events, while maintaining single-digit disease-related mortality.

Relationship between stent characteristics and treatment outcomes in endoscopic transmural drainage of uncomplicated pancreatic pseudocysts. Surg Endosc 2014; 28:2877-83. [PMID: 24789132 DOI: 10.1007/s00464-014-3541-7] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2013] [Accepted: 03/10/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND Transmural stents are placed at endoscopy to drain pancreatic fluid collections. This study evaluated the relationship between stent placement and treatment outcomes in patients undergoing endoscopic transmural drainage of uncomplicated pancreatic pseudocysts. METHODS This is a retrospective study of all patients who underwent endoscopic drainage of uncomplicated pancreatic pseudocysts over a 10-year period. After dilating the transmural tracts in the range of 8-15 mm, single or multiple, 7 or 10Fr double-pigtail plastic stents were deployed. The main outcome measure was to evaluate the relationship between stent characteristics and the number of endoscopic interventions required to achieve resolution of the pancreatic pseudocyst (treatment success). RESULTS Of 122 patients, 45 (36.9%) had 10Fr stents of which 30 patients (66.7%) had more than one stent; the remaining 77 (63.1%) patients had 7Fr stents of which 56 (72.7%) had more than one stent. The overall treatment success was 94.3%. Treatment was successful in 102 patients (83.6%) with one intervention; 13 patients (10.7%) required re-intervention for successful drainage and 7 patients (5.7%) failed endoscopic treatment. There was no significant difference in the number of interventions required for treatment success between patients with 7 or 10Fr stents (one intervention required in 87.7 vs. 90.5%, respectively; p = 0.766) and between patients with 1 or >1 stent (one intervention required in 88.9 vs. 88.6%, respectively; p = 0.999). On multiple logistic regression analysis, the stent size (OR 1.54; 95% CI 0.23-10.4) and number (OR 1.15; 95% CI 0.25-5.25) were not associated with the number of interventions required for treatment success when adjusted for pseudocyst size, location, drainage modality, the presence or absence of pancreatic duct stent and luminal compression. CONCLUSIONS There appears to be no relationship between the number of interventions required for treatment success and stent characteristics in patients undergoing endoscopic transmural drainage of uncomplicated pancreatic pseudocysts.

Abstract
BACKGROUND Endoscopic drainage of the pancreatic pseudocysts has been accepted as a valid alternative to surgical and percutaneous drainage. Endoscopic treatment of the symptomatic walled-off necrosis was not, however, univocally accepted by all authors. THE AIM The aim of this study was to assessed the effectiveness and safety of the endoscopic drainage of walled-off necrosis. METHODS AND MATERIAL Between 2001 and 2011 one hundred and twelve patients with symptomatic walled-off necrosis were treated in the Department of Gastroenterology and Hepatology of the Medical University of Gdansk, using endoscopic drainage. The drainage system was set up by introducing endoprostheses and drains through gastric and duodenal fistulas, transpapillary, and additionally--in cases when the necrosis was spreading outside of the lesser sac--percutaneously. The results and complications of the endoscopic treatment were assessed retrospectively. RESULTS Initial success was achieved in 104/112 (92.9%) patients. Long term success was achieved in 94/112 (83.9%) patients in intention to treat analysis and 94/102 (90.4%) patients in per protocol analysis. Recurrence of pancreatic fluid collection was observed in 19/97(19.6%) patients. Procedure-related complications were observed in 29/112 patients (25.9%). Most of them were treated conservatively. Procedure-related mortality was 1.8%. CONCLUSIONS In a large group of selected patients with symptomatic walled-off necrosis, endoscopic drainage enables high success rate with acceptable complication rate and low procedure-related mortality.

Abstract
Endoscopic therapy has become an essential component in the management of postpancreatitis complications, such as infected and/or symptomatic pancreatic pseudocysts and walled-off necrosis. However, although there have been 2 recent randomized, controlled trials performed, a general lack of comparative effectiveness data regarding the timing, indications, and outcomes of these procedures has been a barrier to the development of practice standards for therapeutic endoscopists managing these issues. This article reviews the available data and expert consensus regarding indications for endoscopic intervention, timing of procedures, endoscopic technique, periprocedural considerations, and complications.

Abstract
Pancreatic necrosis is a local complication of severe acute pancreatitis associated with multiple organ dysfunction, infection and increased mortality. While surgery is the mainstay for invasive management, studies have demonstrated that delaying necrosectomy translates to improved patient outcomes. Minimally invasive therapies have been described both for early and late management of necrotic pancreatic collections and fall into three broad categories: endoscopic, radiology assisted percutaneous drainage and laparoscopic or retroperitoneal surgical techniques. Such interventions may serve as temporizing measures delaying necrosectomy, but more importantly, as best demonstrated in recent randomized controlled trials, can serve as alternative approaches resulting in improved patient outcomes. Access to these techniques is based on their availability at expert centers. Minimally invasive therapies have increased in popularity, with a general consensus among experts being that reduced complications and mortality rates are realized by approaches other than open necrosectomy. However, additional well-designed, randomized trials are needed.
