Both acute and chronic pancreatitis are frequent diseases of the pancreas, which, despite being of benign nature, are related to a significant risk of malnutrition and may require nutritional support. Acute necrotizing pancreatitis is encountered in 20% of patients with acute pancreatitis, is associated with increased morbidity and mortality, and may require artificial nutrition by enteral or parenteral route, as well as additional endoscopic, radiological or surgical interventions. Chronic pancreatitis represents a chronic inflammation of the pancreatic gland with development of fibrosis. Abdominal pain leading to decreased oral intake, as well as exocrine and endocrine failure are frequent complications of the disease. All of the above represent risk factors related to malnutrition. Therefore, patients with chronic pancreatitis should be considered at risk, screened and supplemented accordingly. Moreover, osteoporosis and increased facture risk should be acknowledged in patients with chronic pancreatitis, and preventive measures should be considered.

Acute pancreatitis is one of the most common GI conditions requiring acute hospitalisation and has a rising incidence. In recent years, important insights on the management of acute pancreatitis have been obtained through numerous randomised controlled trials. Based on this evidence, the treatment of acute pancreatitis has gradually developed towards a tailored, multidisciplinary effort, with distinctive roles for gastroenterologists, radiologists and surgeons. This review summarises how to diagnose, classify and manage patients with acute pancreatitis, emphasising the evidence obtained through randomised controlled trials.

Objective: Minimally invasive surgical necrosectomy and endoscopic necrosectomy, compared with open necrosectomy, might improve outcomes in necrotising pancreatitis, especially in critically ill patients. Evidence from large comparative studies is lacking. Design: We combined original and newly collected data from 15 published and unpublished patient cohorts (51 hospitals; 8 countries) on pancreatic necrosectomy for necrotising pancreatitis. Death rates were compared in patients undergoing open necrosectomy versus minimally invasive surgical or endoscopic necrosectomy. To adjust for confounding and to study effect modification by clinical severity, we performed two types of analyses: logistic multivariable regression and propensity score matching with stratification according to predicted risk of death at baseline (low: <5%; intermediate: ≥5% to <15%; high: ≥15% to <35%; and very high: ≥35%). Results: Among 1980 patients with necrotising pancreatitis, 1167 underwent open necrosectomy and 813 underwent minimally invasive surgical (n=467) or endoscopic (n=346) necrosectomy. There was a lower risk of death for minimally invasive surgical necrosectomy (OR, 0.53; 95% CI 0.34 to 0.84; p=0.006) and endoscopic necrosectomy (OR, 0.20; 95% CI 0.06 to 0.63; p=0.006). After propensity score matching with risk stratification, minimally invasive surgical necrosectomy remained associated with a lower risk of death than open necrosectomy in the very high-risk group (42/111 vs 59/111; risk ratio, 0.70; 95% CI 0.52 to 0.95; p=0.02). Endoscopic necrosectomy was associated with a lower risk of death than open necrosectomy in the high-risk group (3/40 vs 12/40; risk ratio, 0.27; 95% CI 0.08 to 0.88; p=0.03) and in the very high-risk group (12/57 vs 28/57; risk ratio, 0.43; 95% CI 0.24 to 0.77; p=0.005). Conclusion: In high-risk patients with necrotising pancreatitis, minimally invasive surgical and endoscopic necrosectomy are associated with reduced death rates compared with open necrosectomy.

Previous studies have shown that the nasogastric (NG) route seems equivalent to the nasojejunal (NJ) route in patients with severe acute pancreatitis (SAP). However, these studies used a small sample size and old criteria for diagnosing SAP, which may include some patients with moderate SAP, according to the newly established SAP criteria (Atlanta 2012 classification). Based on the changes in the criteria for classifying SAP, we performed an up-to-date meta-analysis. Method. We reviewed the PubMed, EMbase, China National Knowledge Infrastructure, Wanfang Database, and Cochrane Central Register of Controlled Trials electronic databases. We included randomized controlled trials comparing NG and NJ nutrition in patients with SAP. We performed the meta-analysis using the Cochrane Collaborations’ RevMan 5.3 software. Results. We included four randomized controlled trials involving 237 patients with SAP. There were no significant differences in the incidence of mortality, infectious complications, digestive complications, achievement of energy balance, or length of hospital stay between the NG and NJ nutrition groups. Conclusions. NG nutrition was as safe and effective as NJ nutrition in patients with SAP. Further studies are needed to confirm our results.

Diseases of the pancreas vary by type, etiology, pathophysiology, and outcomes. One of the principle therapeutic considerations in all types of pancreatic diseases is nutrition. This review will consider acute pancreatitis (AP). Choice of patient, type and composition of nutrition, and timing of initiation will be discussed as components for achieving the maximum benefits of nutrition therapy in AP. The paradigm of nutrition therapy in AP has shifted to early enteral and/or oral nutrition based on disease severity to help mitigate the underlying inflammatory cascade of events leading to AP, beginning with anatomic and functional intestinal changes. Additionally, newer research investigating the inflammatory changes that instigate, maintain, and propagate AP will be discussed in terms of the nutrition effects on systemic inflammation. Nutrition therapy can mitigate the inflammatory changes in the intestinal tract and help with intestinal motility, bacterial overgrowth and translocation. It can help maintain intestinal bacterial composition and abundance similar to predisease levels. This review will also discuss the changes in the intestinal microbiome and effects of probiotics in AP.

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. GRADE methodology was applied to question development, outcome prioritization, evidence quality assessments, and recommendation creation. Results: 88 studies were included and underwent full review. Increasing the time to surgical intervention had an improved outcome in each of the time periods evaluated (72 hours, 12-14, 30 days) with a significant improvement in outcomes if surgery was delayed 30 days. The use of percutaneous and endoscopic procedures were 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 reduce 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. Level of evidence: Systematic review/guideline, level III.

Background and objective The Atlanta classification of acute pancreatitis enabled standardised reporting of research and aided communication between clinicians. Deficiencies identified and improved understanding of the disease make a revision necessary. Methods A web-based consultation was undertaken in 2007 to ensure wide participation of pancreatologists. After an initial meeting, the Working Group sent a draft document to 11 national and international pancreatic associations. This working draft was forwarded to all members. Revisions were made in response to comments, and the web-based consultation was repeated three times. The final consensus was reviewed, and only statements based on published evidence were retained. Results The revised classification of acute pancreatitis identified two phases of the disease: early and late. Severity is classified as mild, moderate or severe. Mild acute pancreatitis, the most common form, has no organ failure, local or systemic complications and usually resolves in the first week. Moderately severe acute pancreatitis is defined by the presence of transient organ failure, local complications or exacerbation of co-morbid disease. Severe acute pancreatitis is defined by persistent organ failure, that is, organ failure >48?h. Local complications are peripancreatic fluid collections, pancreatic and peripancreatic necrosis (sterile or infected), pseudocyst and walled-off necrosis (sterile or infected). We present a standardised template for reporting CT images. Conclusions This international, web-based consensus provides clear definitions to classify acute pancreatitis using easily identified clinical and radiologic criteria. The wide consultation among pancreatologists to reach this consensus should encourage widespread adoption.

Objectives: To assess the influence of infection on mortality in necrotizing pancreatitis. Methods: Eligible prospective and retrospective studies were identified through manual and electronic searches (August 2015). The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). Meta-analyses were performed with subgroup, sensitivity, and meta-regression analyses to evaluate sources of heterogeneity. Results: We included 71 studies (n = 6970 patients). Thirty-seven (52%) studies used a prospective design and 25 scored ≥5 points on the NOS suggesting a low risk of bias. Forty studies were descriptive and 31 studies evaluated invasive interventions. In total, 801 of 2842 patients (28%) with infected necroses and 537 of 4128 patients (13%) with sterile necroses died with an odds ratio [OR] of 2.57 (95% confidence interval [CI], 2.00-3.31) based on all studies and 2.02 (95%CI, 1.61-2.53) in the studies with the lowest bias risk. The OR for prospective studies was 2.96 (95%CI, 2.51-3.50). In sensitivity analyses excluding studies evaluating invasive interventions, the OR was 3.30 (95%CI, 2.81-3.88). Patients with infected necrosis and organ failure had a mortality of 35.2% while concomitant sterile necrosis and organ failure was associated with a mortality of 19.8%. If the patients had infected necrosis without organ failure the mortality was 1.4%. Conclusions: Patients with necrotizing pancreatitis are more than twice as likely to die if the necrosis becomes infected. Both organ failure and infected necrosis increase mortality in necrotizing pancreatitis.

Acute pancreatitis is the most common gastrointestinal indication for hospital admission, and infected pancreatic and/or extrapancreatic necrosis is a potentially lethal complication. Current standard treatment of infected necrosis is a step-up approach, consisting of catheter drainage followed, if necessary, by minimally invasive necrosectomy. International guidelines recommend postponing catheter drainage until the stage of 'walled-off necrosis' has been reached, a process that typically takes 4 weeks after onset of acute pancreatitis. This recommendation stems from the era of primary surgical necrosectomy. However, postponement of catheter drainage might not be necessary, and earlier detection and subsequent earlier drainage of infected necrosis could improve outcome. Strong data and consensus among international expert pancreatologists are lacking. Future clinical, preferably randomized, studies should focus on timing of catheter drainage in patients with infected necrotizing pancreatitis. In this Perspectives, we discuss challenges in the invasive treatment of patients with infected necrotizing pancreatitis, focusing on timing of catheter drainage.
