RESUMEN
BACKGROUND: About 20% of patients with acute pancreatitis develop a necrotising form with a worse prognosis due to frequent appearance of organ failure(s) and/or infection of necrosis. Aims of the present study was to evaluate the "step up" approach treatment of infected necrosis in terms of: feasibility, success in resolving infection, morbidity of procedures, risk factors associated with death and long-term sequels. METHODS: In this observational retrospective monocentric study in the real life, necrotizing acute pancreatitis at the stage of infected walled-off necrosis were treated as follow: first step with drainage (radiologic and/or endoscopic-ultrasound-guided with lumen apposing metal stent); in case of failure, minimally invasive necrosectomy sessions(s) by endoscopy through the stent and/or via retroperitoneal surgery (step 2); If necessary open surgery as a third step. Efficacy was assessed upon to a composite clinical-biological criterion: resolution of organ failure(s), decrease of at least two of clinico-biological criteria among fever, CRP serum level, and leucocytes count). RESULTS: Forty-one consecutive patients were treated. The step-up strategy: (i) was feasible in 100% of cases; (ii) allowed the infection to be resolved in 33 patients (80.5%); (iii) Morbidity was mild and rapidly resolutive; (iv) the mortality rate at 6 months was of 19.5% (significant factors: SIRS and one or more organ failure(s) at admission, fungal infection, size of the largest collection ≥ 16 cm). During the follow-up (median 72 months): 27% of patients developed an exocrine pancreatic insufficiency, 45% developed or worsened a previous diabetes, 24% had pancreatic fistula and one parietal hernia. CONCLUSIONS: Beside a very good feasibility, the step-up approach for treatment of infected necrotizing pancreatitis in the real life displays a clinico-biological efficacy in 80% of cases with acceptable morbidity, mortality and long-term sequels regarding the severity of the disease.

Pancreatic fluid collections (PFCs) are well-known complications of acute pancreatitis. The overinfection of these collections leads to a worsening of the prognosis with an increase in the morbidity and mortality rate. The primary strategy for managing infected pancreatic necrosis (IPN) or symptomatic PFCs is a minimally invasive step-up approach, with endosonography-guided (EUS-guided) transmural drainage and debridement as the preferred and less invasive method. Different stents are available to drain PFCs: self-expandable metal stents (SEMSs), double pigtail stents (DPPSs), or lumen-apposing metal stents (LAMSs). In particular, LAMSs are useful when direct endoscopic necrosectomy is needed, as they allow easy access to the necrotic cavity; however, the rate of adverse events is not negligible, and to date, the superiority over DPPSs is still debated. Moreover, the timing for necrosectomy, the drainage technique, and the concurrent medical management are still debated. In this review, we focus attention on indications, timing, techniques, complications, and particularly on aspects that remain under debate concerning the EUS-guided drainage of PFCs.

BACKGROUND & AIMS: Previous randomized trials, including the Transluminal Endoscopic Step-Up Approach Versus Minimally Invasive Surgical Step-Up Approach in Patients With Infected Pancreatic Necrosis (TENSION) trial, demonstrated that the endoscopic step-up approach might be preferred over the surgical step-up approach in patients with infected necrotizing pancreatitis based on favorable short-term outcomes. We compared long-term clinical outcomes of both step-up approaches after a period of at least 5 years. METHODS: In this long-term follow-up study, we reevaluated all clinical data on 83 patients (of the originally 98 included patients) from the TENSION trial who were still alive after the initial 6-month follow-up. The primary end point, similar to the TENSION trial, was a composite of death and major complications. Secondary end points included individual major complications, pancreaticocutaneous fistula, reinterventions, pancreatic insufficiency, and quality of life. RESULTS: After a mean follow-up period of 7 years, the primary end point occurred in 27 patients (53%) in the endoscopy group and in 27 patients (57%) in the surgery group (risk ratio [RR], 0.93; 95% confidence interval [CI], 0.65-1.32; P = .688). Fewer pancreaticocutaneous fistulas were identified in the endoscopy group (8% vs 34%; RR, 0.23; 95% CI, 0.08-0.83). After the initial 6-month follow-up, the endoscopy group needed fewer reinterventions than the surgery group (7% vs 24%; RR, 0.29; 95% CI, 0.09-0.99). Pancreatic insufficiency and quality of life did not differ between groups. CONCLUSIONS: At long-term follow-up, the endoscopic step-up approach was not superior to the surgical step-up approach in reducing death or major complications in patients with infected necrotizing pancreatitis. However, patients assigned to the endoscopic approach developed overall fewer pancreaticocutaneous fistulas and needed fewer reinterventions after the initial 6-month follow-up.

BACKGROUND: A step-up approach is recommended as a new treatment algorithm for pancreatic fluid collections (PFCs). However, determining which patients with PFCs require a step-up approach after endoscopic ultrasound-guided transmural drainage (EUS-TD) is unclear. If the need for a step-up approach could be predicted, it could be performed early for relevant patients. We aimed to identify PFC-related predictive factors for a step-up approach after EUS-TD. METHODS: This retrospective cohort study included consecutive patients who had undergone EUS-TD for PFCs from January 2008 to May 2020. Multivariable logistic regression analyses were performed to investigate PFC factors related to requiring a step-up approach. A step-up approach was performed for patients who did not respond clinically to EUS-TD. RESULTS: We enrolled 81 patients, of whom 25 (30.9%) required a step-up approach. In multivariate logistic regression analysis, the pre-EUS-TD number of PFC-occupied regions ≥ 3 (multivariate odds ratio [OR] 16.2, 95% confidence interval [CI] 2.68-97.6, P = 0.002), the post-EUS-TD PFC-remaining percentage ≥ 35% (multivariate OR 19.9, 95% CI 2.91-136.1, P = 0.002), and a positive sponge sign, which is a distinctive computed tomography finding in the early stage after EUS-TD (multivariate OR 6.26, 95% CI 1.33-29.3, P = 0.020), were independent predictive factors associated with requiring a step-up approach for PFCs. CONCLUSION: Pre-EUS-TD PFC-occupied regions, post-EUS-TD PFC-remaining percentage, and a positive sponge sign were predictors of the need for a step-up approach. Patients with PFC with these findings should be offered a step-up approach whereas conservative treatment is recommended for patients without these findings.

Background and objectives: Symptomatic walled-off pancreatic necrosis is a serious local complication of acute necrotising pancreatitis. The endoscopic step-up approach is the standard treatment for symptomatic walled-off pancreatic necrosis; however, adjunctive radiologic percutaneous drainage for this condition is controversial. This study compared the clinical and radiologic resolution of walled-off pancreatic necrosis achieved with the endoscopic step-up approach with or without radiology-guided percutaneous drainage. Material and Methods: This retrospective, single-centre cohort study enrolled patients with symptomatic walled-off pancreatic necrosis who underwent endoscopic transmural drainage (ETD) followed by directed endoscopic necrosectomy (DEN) with or without radiology-guided drainage. A total of 34 patients (endoscopic approach, n = 22; combined modality approach, n = 12) underwent the endoscopic step-up approach (ETD followed by DEN). Baseline characteristics, clinical success, and resolution of necrosis were compared between groups. Results: All patients achieved symptom resolution from walled-off pancreatic necrosis. The mean patient age was 58.4 years, and 21 (61.8%) were men. Following treatment with the endoscopic approach and combined modality approach, clinical success was achieved in 90.9% of patients within 11.5 days, and 66.7% of patients within 16.5 days, respectively. Both length of hospital stay (55 days vs. 71 days; p = 0.071) and time to complete radiologic resolution were shorter (93 days vs. 124 days; p = 0.23) in the endoscopic approach group. Conclusion: Both the endoscopic step-up approach and the CMD approach resulted in a favourably high clinical resolution rates in patients with symptomatic WON. However, clinical success rates seemed to be higher, and the length of hospital stay tended to be shorter in the endoscopic approach than in the CMD approach, as well as the significantly shorter necrosectomy time in each procedure was observed. Of note, these findings might be from some inherited differences in baseline characteristics of the patients between the two groups, and a randomized controlled trial with a larger sample size to verify these results is warranted.

INTRODUCTION: The incidence of acute pancreatitis has been increasing over the past twenty years and there is still no causal treatment available. Although cases of severe acute pancreatitis account for only about a fifth of all cases of acute pancreatitis, high morbidity and lethality call for an optimization and unification of treatment procedures. METHODS: We operated on 27 patients suffering from severe acute pancreatitis in the past five years. We compared selected parameters such as gender, age, body mass index, aetiology, presence of type 2 diabetes, BISAP score, previous minimally invasive treatment and presence of the intraabdominal compartment syndrome. RESULTS: The average age of men and women was similar in our group. Most patients were overweight or obese. Alcoholic aetiology was more common in men while biliary aetiology prevailed in women. The mortality rate was 26% in our group. The intra-abdominal compartment syndrome followed by emergency decompression surgery was present in one fourth of the patients. A minimally invasive approach was used in approximately in one half of the patients, and surgical treatment was used only in cases where the minimally invasive approach failed. CONCLUSION: After each surgical revision, clinical deterioration of the patient´s condition occurs during the first two to three days in response to operative stress. Therefore, the current trend in the treatment of acute pancreatitis is to proceed as conservatively as possible, or using the minimally invasive approach, and surgical treatment should be reserved only for conditions that cannot be managed otherwise. If surgical treatment is used, it is advisable to perform cholecystectomy, whatever the aetiology of the pancreatitis.

INTRODUCTION: The minimally invasive step-up approach to pancreatitis improves outcomes. Multidisciplinary working groups may best facilitate this approach. However, support for these working groups requires funding. We hypothesize that patients requiring surgical debridement generate sufficient revenue to sustain these working groups. Furthermore, patients selected for surgical debridement by the working group will have a higher rate of percutaneous and endoscopic intervention in adherence to the step-up approach. METHODS: We conducted an observational cohort study of all patients with severe acute and/or necrotizing pancreatitis whose care was overseen by our multidisciplinary working group (October 2015 through January 2019). Patient demographics, hospital treatments, and outcomes data were compared between those who underwent surgical debridement and those who did not. Hospital billing data were also collected from those who are undergoing surgical debridement and compared to institutional benchmarks for financial sustainability. RESULTS: A total of 108 patients received care overseen by the working group, 10 of which progressed to surgical debridement. The mean contribution margin percentages for each patient in the surgical debridement group were higher than the threshold value for financial sustainability, 39% (60.34% ± 16.66%; P = 0.004). Patients in the surgical debridement group were more likely to undergo intervention by interventional radiologist (odds ratio, 1.58; P = 0.005). The mortality was higher in the nonsurgical debridement group (odds ratio, 15; P = 0.008). CONCLUSIONS: Our multidisciplinary working group delivered step-up care to patients with pancreatitis. Patients requiring surgical debridement generated a significantly positive contribution margin that could be used to help support the costs associated with providing multidisciplinary care.

Current management of infected pancreatic necrosis is focused on a minimally invasive step-up approach. The step-up approach consists of initial percutaneous or endoscopic drainage of infected pancreatic necrosis, followed, if necessary, by minimally invasive surgical or endoscopic debridement. While there is reduced morbidity and mortality, vascular complications can be life-threatening. Reported vascular complications have been limited to arterial bleeding. Venous bleeding has not been previously reported. We present two cases of portal venous bleeding in patients who underwent treatment for infected pancreatic necrosis with a step-up approach. We discuss the clinical presentation, diagnosis, and initial management. Moreover, we present two different techniques that can be used to successfully manage venous bleeding in patients who have percutaneous drains in place as part of a step-up approach. These techniques involve tamponading the cavity or drain tract with topical hemostatics and direct embolization of the bleeding vein. These experiences can serve as a guide for managing portal venous bleeding in patients with infected pancreatic necrosis.

Objective: To examine the effect of the "four-steps" treatment on infectious pancreatic necrosis(IPN). Methods: The data of 207 patients who were diagnosed with IPN from January 2013 to December 2017 at Department of Pancreaticobiliary Surgery, the First Affiliated Hospital of Harbin Medical University were analyzed retrospectively. Among 207 patients, 132(63.8%) were males and 75(36.2%) were females. The median age was 45 years old (range: 19 to 80 years old). One hundred and fifty-eight patients(76.3%) suffered severe acute pancreatitis and 49 patients(23.7%) suffered moderately severe acute pancreatitis. Percutaneous catheter drainage(PCD) was performed on all the patients(Step 1). Patients received "four-steps" minimally invasive treatment strategy in step-up group(173 patients). The following steps after PCD were mini-incision access pancreatic necrosectomy(MIAPN) (Step 2), sinus tract endoscopic debridement and(or) PCD for residual infections(Step 3) and finally conventional open pancreatic necrosectomy(OPN) (Step 4). Patients(34 cases) received conventional open pancreatic necrosectomy after invalided PCD in OPN group. The perioperative parameters and prognosis were compared between Step-up group and OPN group. Normally distributed quantitative variables were analyzed by t-test, non-normally distributed quantitative variables were analyzed by Wilcoxon chi-square test and categorical variables were analyzed by χ(2) test or Fisher exact test, respectively. Results: The basic characteristics of the two groups of patients were similar, but the referral rate of patients and the rate of preoperative 3 days organ failure in the OPN group were significantly higher than those of step-up group patients(47.1% vs. 28.9%, χ(2)=4.313, P=0.038; 26.5% vs. 9.2%, χ(2)=2.819, P=0.011). The frequency of PCD and the number of PCD tube (root) were less than those in the step-up group(1(1) vs. 2(1), Z=-3.373, P=0.018; 2(1) vs. 3(2), Z=-2.208, P=0.027). Compared with the OPN group, the interval time from onset to surgery and the MIAPN operation time were significantly shorter in the step-up group(29(15) days vs. 36(17)days, Z=-0.567, P=0.008; 58(27)minutes vs. 90(56)minutes, Z=-3.908, P<0.01); postoperative mortality was lower(5.8% vs.17.6%, χ(2)=4.070, P=0.044); the overall incidence of postoperative complications was reduced(23.1% vs. 55.9%, χ(2)=14.960, P<0.01) and the incidence of new-onset organ failure was decreased after operation in the step-up group(37.5% vs.47.4%, χ(2)=7.133, P=0.007). The incidence of local abdominal complications (pancreatic fistula, intra-abdominal hemorrhage, gastrointestinal fistula) showed no significant difference between the two groups (P>0.05). Fewer patients required ICU treatment after operation in the step-up group compared with OPN group(22.0% vs. 44.1%, χ(2)=6.204, P=0.013). Patients in the Step-up group has shorter hospital stay than patients in OPN group (46(13) days vs. 52(13)days, Z=-1.993, P=0.046). Conclusions: The clinical effects of "four-steps" exhibited the superiority of minimally invasive treatment of IPN.And MIAPN is a simple, safe and effective procedure to remove pancreatic necrotic tissue and decrease complications.

With the development of minimally invasive concept, the treatment mode of severe acute pancreatitis has changed greatly. The tendency of surgical intervention has changed from excessive intervention to inadequate intervention. The timing of intervention has changed from earlier to later, and the mode of intervention has changed from openness as the main way to minimally invasive as the guidance. The transformation of surgical intervention tendency conforms to both minimally invasive trend and the step-up approach, but there are still some shortcomings: inadequate surgical intervention, inappropriate timing and indications, and over dependence on minimally invasive surgery. Correctly grasping the indications of surgical intervention, accurately grasping the timing of surgical intervention, and reasonably choosing the mode of surgical intervention are the keys to solve the insufficiency of surgical intervention. Laying emphasis on multidisciplinary team and correctly recognizing the role and status of surgical intervention can effectively reduce the mortality of severe acute pancreatitis patients.

BACKGROUND: Infected pancreatic necrosis, which occurs in about 40% of patients admitted for acute necrotizing pancreatitis, requires combined antibiotic therapy and local drainage. Since 2010, drainage by open surgical necrosectomy has been increasingly replaced by less invasive methods such as percutaneous radiological drainage, endoscopic necrosectomy, and laparoscopic surgery, which proved effective in small randomized controlled trials in highly selected patients. Few studies have evaluated minimally invasive drainage methods used under the conditions of everyday hospital practice. The aim of this study was to determine whether, compared with conventional open surgery, minimally invasive drainage was associated with improved outcomes of critically ill patients with infection complicating acute necrotizing pancreatitis. METHODS: A single-center observational study was conducted in patients admitted to the intensive care unit for severe acute necrotizing pancreatitis to compare the characteristics, drainage techniques, and outcomes of the 62 patients managed between September 2006 and December 2010, chiefly with conventional open surgery, and of the 81 patients managed between January 2011 and August 2015 after the introduction of a minimally invasive drainage protocol. RESULTS: Surgical necrosectomy was more common in the early period (74% versus 41%; P <0.001), and use of minimally invasive drainage increased between the early and late periods (19% and 52%, respectively; P <0.001). The numbers of ventilator-free days and catecholamine-free days by day 30 were higher during the later period. The proportions of patients discharged from intensive care within the first 30 days and from the hospital within the first 90 days were higher during the second period. Hospital mortality was not significantly different between the early and late periods (19% and 22%, respectively). CONCLUSION: In our study, the implementation of a minimally invasive drainage protocol in patients with infected pancreatic necrosis was associated with shorter times spent with organ dysfunction, in the intensive care unit, and in the hospital. Mortality was not significantly different. These results should be interpreted bearing in mind the limitations inherent in the before-after study design.

BACKGROUND: The timing of surgery in patients not responding to percutaneous catheter drainage (PCD) in infected pancreatic necrosis remains challenging. MATERIALS AND METHODS: A randomized controlled trial was designed to establish the optimal timings of surgery following PCD in patients with infected pancreatic necrosis (IPN). Patients who did not improve by day 10 after PCD insertion were included in the present study and were randomized to group A (step-up approach as a bridge to surgery) or group B (step-up approach with intention to avoid surgery). Weekly inflammatory and nutritional markers were monitored in both groups (clinical trials. gov identifier NCT-01527084). RESULTS: From July 2011 to December 2012, 40 patients underwent treatment with PCD. The first 8 patients were randomized into two groups. The trial was stopped prematurely because of difficulty in accrual and poor progress. All subsequent patients were managed with step-up approach with the intention to avoid surgery. Of 35 patients, 24 patients were managed by PCD alone while 11 patients required surgery. In patients who did not require surgery; levels of serum high sensitivity C-reactive protein (hsCRP), interleukin-6(IL6) and prealbumin showed a falling trend. This group also had higher baseline albumin and higher albumin at 4 weeks. CONCLUSION: During the present study, randomization into surgery at a predetermined time in step-up approach was discontinued due to poor progress. Step-up approach with the intention to avoid surgery led to a success rate of 68.5%. The present study failed to predict the optimal timing of surgery after PCD. Patients who needed surgery were sicker at the time of admission, had higher incidence of organ failure, and spent more time in the ICU compared to patients who did not need surgery. In future, inflammatory and nutritional markers may be useful to identify patients who are unlikely to respond to PCD and may help determine the timing of surgery.

AIM: Present study reports the long term functional and morphological changes following severe acute pancreatitis and compares patients managed by operative and non-operative methods. Association between morphological changes and functional parameters were studied. MATERIALS AND METHODS: 35 patients with one year of follow up after recovery from attack of acute pancreatitis were evaluated. RESULTS: Etiology was alcohol in 19, gallstones in 11 and idiopathic in 5. Fourteen patients were managed non-operatively and 21 operatively. Patients in non-operative group had a mean follow-up of 18.4 ± 8.2 months while patients in necrosectomy group had 31.4 ± 20.6 months. 40% patients had exocrine insufficiency (abnormal fecal fat) while 48.5% patients (17/35) had new onset diabetes. 90% patients had morphological changes in pancreas. Exocrine abnormality was significantly higher in necrosectomy group compared to non-operative group (57.2% vs 14.1%, p = 0.01). Patients undergoing necrosectomy had higher incidence of endocrine dysfunction {61.9% in surgery and 28.5% in non-operative group (p = 0.053)}. Operative group had more number of patients with completely non-visualized main pancreatic duct (MPD) (p = 0.028) and non-operative group had significantly higher irregular MPD (p = 0.021). Exocrine dysfunction was more in patients with complete non-visualization of MPD and/or incompletely visualized MPD (p = 0.013). CONCLUSION: Patients managed non-operatively had significantly less exocrine and endocrine dysfunction compared to operated patients. Exocrine dysfunction was significantly associated with complete non-visualization of MPD and/or incompletely visualized MPD.

GOALS AND BACKGROUND: We evaluated ex and in vivo effect of streptokinase on pancreatic necrosum to improve the success rate of pigtail catheter drainage and irrigation in infected walled off pancreatic necrosis using step up approach and also looked at potential risk of bleeding. EXPERIMENT AND CLINICAL CASES: 1000 IU/ml of streptokinase was added to 10 g. of intra-operatively obtained fresh tissue of peripancreatic necrosis and results compared to treatment with saline. Mixture was incubated for 12 h in thermostat at 37.5 °C and subjected to histopathology. Subsequently streptokinase (50,000 units thrice a day for 5 days through PCD) was used in two patients with walled off pancreatic necrosis (WOPN) not responding to step up approach and who were being considered for surgery. Grossly there was fragmentation of necrosum in streptokinase treated tissue. Microscopically complete loss of supportive collagenous framework was noted in streptokinase treated necrosum with clumping of necrotic tissue into structure-less mass. No such changes were discernible in saline treated tissue. In two patients with WOPN there was clearance of debris after streptokinase instillation. None of the patients was on thromboprophylaxis and bleeding was not noticed in any of the patients. CONCLUSION: Based on ex vivo effect of streptokinase in dissolution of necrosum at periphery, we believe that in patients with walled off pancreatic necrosis (WOPN) not responding to pigtail catheter drainage and saline irrigation; streptokinase may prove to be useful adjunct.

Paraduodenal pancreatitis (PP), also known as groove pancreatitis (GP), is a rare and distinct variant of chronic pancreatitis and presents significant diagnostic and therapeutic challenges. This comprehensive case study explores a 54-year-old male patient's journey, highlighting the intricate relationship between clinical presentation, diagnostic modalities, and management strategies. Despite a history of smoking and alcohol consumption, the diagnosis of PP was primarily reliant on advanced imaging techniques, including computed tomography and magnetic resonance imaging, which revealed characteristic findings of GP. The case underscores the importance of a high index of suspicion and a step-up approach to management, starting with conservative treatment and progressing to surgical intervention as necessary. This study contributes to the growing body of knowledge on PP, emphasizing the need for awareness and understanding of this rare condition to improve patient outcomes.
RESUMEN
Background The clinical spectrum of acute pancreatitis (AP) ranges from mild disease to severe form associated with multiorgan failure, prolonged hospital stay, high morbidity, and mortality. Acute necrotizing pancreatitis (ANP) is a severe form of AP. This study evaluates AP's outcomes after applying principles of the step-up approach in a tertiary healthcare center in south India. Methodology This prospective observational study was carried out from January 2021 to December 2022. The study population includes patients admitted to our department with AP. Results Ninety patients were included in the study, most of them were middle-aged males with ethanol ingestion as the common etiology. Thirty-seven (41.1%) patients had mild AP, 25 (27.7%) had moderately severe AP, and 28 (31.1%) had severe AP. Organ failure at admission was noted in 36 (40%) patients. Twenty-three (25.5%) patients developed ANP. Infected necrosis was noted in 3 (3.33%) patients. Eighteen (20%) patients needed image-guided percutaneous drainage. Seven (38.8%) needed necrosectomy following percutaneous drainage. Mortality was observed in 8 (8.8%) patients. Specifically, mortality was noted in 6 (6.6%) patients who presented later in their disease course. Conclusions Percutaneous catheter drainage is a safe and effective therapy to tide over the initial phase of AP. It also serves as a bridging therapy till the patient is clinically fit for a necrosectomy. Severe AP cases presenting late in their course are associated with significant mortality even after step-up management. Standardized protocols for referral and management are essential to obtain a good clinical outcome.
RESUMEN
INTRODUCTION AND IMPORTANCE: The incidence of acute pancreatitis varies globally, and its rates are increasing. Timely intervention in cases of infected necrosis is crucial to effective management. The landscape of acute pancreatitis management has undergone transformation through adopting a "step-up" strategy, accentuating the shift towards minimally invasive techniques. CASE PRESENTATION: A 63-year-old patient with acute pancreatitis and infected pancreatic necrosis underwent a challenging yet successful treatment using video-assisted retroperitoneal debridement employing a two-port approach facilitated access for an intricate area. The procedure, performed 45 days after admission, effectively reduced peripancreatic collections, demonstrating the efficacy of this approach in managing complex cases of infected pancreatic necrosis. CLINICAL DISCUSSION: The management of acute pancreatitis has evolved towards a comprehensive strategy involving early hydration, nutritional support, effective pain management, and interventions. Infected pancreatic necrosis poses a serious complication, with minimally invasive techniques such as video-assisted retroperitoneal debridement (VARD) emerging as preferred options. The efficacy and safety of VARD in complex cases are highlighted, although challenges persist, especially in extensive necrosis. CONCLUSION: The VARD procedure, a key component of the step-up approach, exhibits a remarkable safety profile, substantially reducing postoperative complications and mortality compared to open surgical counterparts. However, challenges persist in managing cases of infected Walled-Off Necrosis with deep extension, necessitating carefully considering a minimal-access approach. We report our experience using the VARD in a two-port approach.
RESUMEN
BACKGROUND AND AIMS: Minimally invasive step-up interventions are now the standard treatment recommended by current guidelines for symptomatic pancreatic necrotic fluid collections (PNFC); however, it is controversial whether delayed treatment after four weeks should always be used in patients who have failed conservative treatment and whose condition has not improved or worsened. The aim of this meta-analysis was to evaluate the impacts of the different timing of interventions on the clinical outcomes and prognosis of patients with symptomatic PNEC requiring intervention. METHODS: We searched Embase, Cochrane Library, PubMed and Web of Science databases to identify comparative studies assessing the safety and efficacy of early and postponed interventions in treating symptomatic PNFC. PRIMARY OUTCOME: Mortality. Secondary outcomes included some major complications, need for further minimally invasive necrosectomy and length of hospital stay. RESULTS: This meta-analysis included ten studies (2 RCTs and 8 observational studies) with a total of 1178 symptomatic PNFC patients who required intervention. Pooled results showed that there was no significant difference between early minimally invasive intervention and postponed intervention in mortality(OR 1.41, 95%CI 0.93-2.12;p = 0.10) and the incidence of early and late complications, but the early intervention group had a significantly increased need for further minimally invasive necrosectomy compared with postponed intervention (OR 2.04,95%CI 1.04-4.03; p = 0.04). There was no increase in length of stay for patients who received early intervention compared to postponed drainage (MD 3.53, 95% CI -4.20, 11.27; p = 0.37). CONCLUSION: Intervention before four weeks should be considered for patients with PNFC complicated by persistent organ failure or infections, who have been treated conservatively to the maximum extent possible.

Purpose: Necrotizing pancreatitis (NP) complicated by gastrointestinal fistula is challenging and understudied. As the treatment of necrotizing pancreatitis changed to a step-up strategy, we attempted to evaluate the incidence, risk factors, clinical outcomes and treatment of gastrointestinal fistulas in patients receiving a step-up approach. Methods: Clinical data from 1274 patients with NP from 2014-2022 were retrospectively analyzed. Multivariable logistic regression analysis was conducted to identify risk factors and propensity score matching (PSM) to explore clinical outcomes in patients with gastrointestinal fistulas. Results: Gastrointestinal fistulas occurred in 8.01% (102/1274) of patients. Of these, 10 were gastric fistulas, 52 were duodenal fistulas, 14 were jejunal or ileal fistulas and 41 were colonic fistulas. Low albumin on admission (OR, 0.936), higher CTSI (OR, 1.143) and invasive intervention prior to diagnosis of gastrointestinal fistula (OR, 5.84) were independent risk factors for the occurrence of gastrointestinal fistula, and early enteral nutrition (OR, 0.191) was a protective factor. Patients who developed a gastrointestinal fistula were in a worse condition on admission and had a poorer clinical outcome (p<0.05). After PSM, both groups of patients had similar baseline information and clinical characteristics at admission. The development of gastrointestinal fistulas resulted in new-onset persistent organ failure, increased open surgery, prolonged parenteral nutrition and hospitalization, but not increased mortality. The majority of patients received only conservative treatment and minimally invasive interventions, with 7 patients (11.3%) receiving surgery for upper gastrointestinal fistulas and 11 patients (26.9%) for colonic fistulas. Conclusion: Gastrointestinal fistulas occurred in 8.01% of NP patients. Independent risk factors were low albumin, high CTSI and early intervention, while early enteral nutrition was a protective factor. After PSM, gastrointestinal fistulas resulted in an increased proportion of NP patients receiving open surgery and prolonged hospitalization. The majority of patients with gastrointestinal fistulas treated with step-up therapy could avoid surgery.
RESUMEN
Introduction and importance: Fluid collection is a critical complication of acute necrotizing pancreatitis. It is usually formed near the pancreas, but unusual collection sites have also been reported. Anterior extraperitoneal or preperitoneal collections following acute pancreatitis are rare and must be differentiated from pancreatic ascites, which is a collection of fluid in peritoneal cavity. Case presentation: A 68-year-old man with a suspected pancreatic mass presented to the emergency department, complaining of abdominal pain and gradual abdominal distention. He had experienced epigastric pain, nausea, vomiting, progressive abdominal distention, and icterus for two weeks prior to admission. An abdominopelvic CT scan revealed extensive necrotizing pancreatitis with a prominent extraperitoneal collection. The collection had extended from the retroperitoneal space to the anterior extraperitoneal or preperitoneal space and had pushed the abdominal viscera backward. We managed the patient with the "Step-up" approach, and the patient was discharged after four weeks. Clinical discussion & conclusion: Preperitoneal fluid collection can rarely occur following acute necrotizing pancreatitis. Here, we suggested two possible routes for fluid migration from the retroperitoneum to the preperitoneal space. Using minimally invasive techniques such as percutaneous drainage of peripancreatic collections could reduce morbidity and mortality in critically ill patients diagnosed with necrotizing pancreatitis.
