Abstract
Approximately 20%-30% of patients with acute necrotizing pancreatitis develop infected pancreatic necrosis (IPN), a highly morbid and potentially lethal complication. Early identification of patients at high risk of IPN may facilitate appropriate preventive measures to improve clinical outcomes. In the past two decades, several markers and predictive tools have been proposed and evaluated for this purpose. Conventional biomarkers like C-reactive protein, procalcitonin, lymphocyte count, interleukin-6, and interleukin-8, and newly developed biomarkers like angiopoietin-2 all showed significant association with IPN. On the other hand, scoring systems like the Acute Physiology and Chronic Health Evaluation II and Pancreatitis Activity Scoring System have also been tested, and the results showed that they may provide better accuracy. For early prevention of IPN, several new therapies were tested, including early enteral nutrition, antibiotics, probiotics, immune enhancement, etc., but the results varied. Taken together, several evidence-supported predictive markers and scoring systems are readily available for predicting IPN. However, effective treatments to reduce the incidence of IPN are still lacking apart from early enteral nutrition. In this editorial, we summarize evidence concerning early prediction and prevention of IPN, providing insights into future practice and study design. A more homogeneous patient population with reliable risk-stratification tools may help find effective treatments to reduce the risk of IPN, thereby achieving individualized treatment.

Abstract
BACKGROUND Continuous regional arterial infusion (CRAI) of protease inhibitor nafamostat mesilate (NM) is used in the context of predicted severe acute pancreatitis (SAP) to prevent the development of pancreatic necrosis. Although this therapy is well known in Japan, its efficacy and safety remain unclear. METHODS This investigator-initiated and -driven, multicenter, open-label, randomized, controlled trial (UMIN000020868) enrolled 39 patients with predicted SAP and low enhancement of the pancreatic parenchyma on computed tomography (CT). Twenty patients were assigned to the CRAI group, while 19 served as controls and were administered NM at the same dose intravenously (IV group). The primary endpoint was the development of pancreatic necrosis as determined by CT on Day 14, judged by blinded central review. RESULTS There was no difference between the CRAI and IV groups regarding the percentages of participants who developed pancreatic necrosis (more than 1/3 of the pancreas: 25.0%, range 8.7-49.1% vs. 15.8%, range 3.4-39.6%, respectively, P = 0.694; more than 2/3 of the pancreas: 20%, range 5.7-43.7% vs. 5.3%, range 0.1-26.0%, respectively, P = 0.341). The early analgesic effect was evaluated based on 24-h cumulative fentanyl consumption and additional administration by intravenous patient-controlled analgesia. The results showed that the CRAI group used significantly less analgesic. There were two adverse events related to CRAI, namely bleeding and splenic infarction. CONCLUSIONS CRAI with NM did not inhibit the development of pancreatic necrosis although early analgesic effect of CRAI was superior to that of IV. Less-invasive IV therapy can be considered a viable alternative to CRAI therapy.

Abstract
Introduction Acute pancreatitis (AP) is a common emergency presentation and can be disabling. There is significant morbidity and mortality associated with AP, and it places a considerable burden on the healthcare system. Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to have a protective effect in some elective contexts. This retrospective study aimed to evaluate the effect of NSAIDs on the course of AP and the severity of the disease. Methods A retrospective analysis was carried out of 324 patients admitted as an emergency with a diagnosis of AP to two UK hospitals. Patients were divided into two groups: those already taking NSAIDs for other co-morbidities and those not taking NSAIDs. Variables compared included: admission to a high dependency or intensive care unit; pancreatic necrosis; pseudocyst development; need for surgery; serum inflammatory markers; modified early warning scores on days 1, 3 and 5; length of stay; and mortality. Results Patients not taking NSAIDs were more likely to have a C-reactive protein level of ≥150mg/l (p=0.007). Patients in the NSAID group experienced less pancreatic necrosis (p=0.019) and lower rates of pseudocyst formation (p=0.010). Other variables showed no difference between the two groups, specifically length of stay and mortality. Conclusions Routine NSAID use may exert a protective effect on the development of AP, its severity, and complications. Therapeutic use of NSAIDs in acute presentations with pancreatitis should be further evaluated.

Abstract
INTRODUCTION The development of pancreatic infection is associated with the development of a deteriorating disease with subsequent high morbidity and mortality. There is agreement that in mild pancreatitis there is no need to use antibiotics; in severe pancreatitis it would appear to be a logical choice to use antibiotics to prevent secondary pancreatic infection and decrease associated mortality. MATERIALS AND METHODS A non-systematic review of current evidence, meta-analyses and randomized controlled trials was conducted to assess the role of prophylactic antibiotics in acute pancreatitis and whether it might improve morbidity and mortality in pancreatitis. RESULTS Mixed evidence was found to support and refute the role of prophylactic antibiotics in acute pancreatitis. Most studies have failed to demonstrate much benefit from its routine use. Data from our unit suggested little benefit of their routine use, and showed that the mortality of those treated with antibiotics was significantly higher compared with those not treated with antibiotics (9% vs 0%, respectively, P = 0.043). In addition, the antibiotic group had significantly higher morbidity (36% vs 5%, respectively, P = 0.002). CONCLUSIONS Antibiotics should be used in patients who develop sepsis, infected necrosis-related systemic inflammatory response syndrome, multiple organ dysfunction syndrome or pancreatic and extra-pancreatic infection. Despite the many other factors that should be considered, prompt antibiotic therapy is recommended once inflammatory markers are raised, to prevent secondary pancreatic infection. Unfortunately, there remain many unanswered questions regarding the indications for antibiotic administration and the patients who benefit from antibiotic treatment in acute pancreatitis.

Abstract
BACKGROUND & AIMS Pancreatitis is a source of substantial morbidity and health cost in the United States. Little is known about how diet might contribute to its pathogenesis. To characterize dietary factors that are associated with risk of pancreatitis by disease subtype, we conducted a prospective analysis of 145,886 African Americans, Native Hawaiians, Japanese Americans, Latinos, and whites in the Multiethnic Cohort. METHODS In the Multiethnic Cohort (age at baseline, 45-75 y), we identified cases of pancreatitis using hospitalization claim files from 1993 through 2012. Patients were categorized as having gallstone-related acute pancreatitis (AP) (n = 1210), AP not related to gallstones (n = 1222), or recurrent AP or suspected chronic pancreatitis (n = 378). Diet information was obtained from a questionnaire administered when the study began. Associations were estimated by hazard ratios and 95% confidence intervals using Cox proportional hazard models adjusted for confounders. RESULTS Dietary intakes of saturated fat (P trend = .0011) and cholesterol (P trend = .0008) and their food sources, including red meat (P trend < .0001) and eggs (P trend = .0052), were associated positively with gallstone-related AP. Fiber intake, however, was associated inversely with gallstone-related AP (P trend = .0005) and AP not related to gallstones (P trend = .0035). Vitamin D, mainly from milk, was associated inversely with gallstone-related AP (P trend = .0015), whereas coffee consumption protected against AP not related to gallstones (P trend < .0001). With the exception of red meat, no other dietary factors were associated with recurrent acute or suspected chronic pancreatitis. CONCLUSIONS Associations between dietary factors and pancreatitis were observed mainly for gallstone-related AP. Interestingly, dietary fiber protected against AP related and unrelated to gallstones. Coffee drinking protected against AP not associated with gallstones. Further studies are warranted to confirm our findings.

Abstract
Acute pancreatitis (AP) is a painful inflammatory disorder of the exocrine pancreas, ranking as the most common gastrointestinal reasons for hospitalization with no specific therapy currently. Diosgenyl saponins extracted from natural products and diosgenin or its derivatives have been shown to exert anti-inflammatory effects in various diseases. However, the therapeutic effects of diosgenyl saponins from Dioscorea zingiberensis C. H. Wright in AP have not yet been determined. Five compounds were extracted and screened for taurocholate-induced necrosis in mouse pancreatic acinar cells. Particularly, 26-O-β-d-glucopyranosyl-3β, 22α, 26-trihydroxy-25(R)-furosta-5-en-3-O-[α-L-rhamnopyranosyl-(1 → 4)]-β-d-glucopyranoside (compound 1) exhibited the best protective effects with no toxicity observed. Next, we showed compound 1 concentration-dependently inhibited necrotic cell death pathway activation and 2.5 mM compound 1 also prevented the loss of mitochondrial membrane potential, adenosine triphosphate production, and reactive oxygen species generation in mouse pancreatic acinar cells. Finally, we showed compound 1 protected against three clinically representative murine models of AP and significantly improved pancreatitis-associated acute lung injury. These data provide in vitro and in vivo evidence that one compound of diosgenyl saponins can be potential treatment for AP. This study suggests natural saponins may serve as fruitful sources for exploring/identifying potential therapies for inflammatory diseases.

Abstract
We investigated and compared 2 clinical strategies to prevent postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP).We retrospectively reviewed data from patients who underwent ERCP between 2008 and 2014. Of 623 patients at high risk for PEP, 145 were treated with prophylactic pancreatic stent placement (PSP) only, and 478 were treated with rectal indomethacin (RI) only, for PEP prevention. Patients were matched by one-to-one propensity score matching (PSM) by risk factors, with overall PEP incidence as primary outcome, and moderate or severe PEP and complication rates as secondary outcomes.Of 623 patients with high-risk factors, 145 pairs were generated after PSM. Thirty-two patients developed pancreatitis-10 (6.9 %) in the PSP group and 22 (15.2 %) in the RI group (P = 0.025). Moderate-to-severe pancreatitis developed in 5 patients (2.8%) in the PSP group and 14 patients (9.7 %) in the RI group (P = 0.047).Although indomethacin represents an easy, inexpensive treatment, prophylactic PSP is still the better prevention strategy for PEP.

Abstract
UNLABELLED Endoscopic retrograde cholangiopancreatography (ERCP) is the most important non-surgical procedure in serious pancreatic and biliary diseases, still burdened with the risk of severe complications. The objective of the study was to distinguish factors which could increase the risk of occurrence of ERCP complication in the form of pancreatitis. MATERIAL AND METHODS The study included 452 patients who had undergone ERCP. Patients' records were retrospectively analyzed from the aspect of demographic data, indications for the procedure, type and course of the procedure, type and severity of complications, width of the common bile duct (CBD), concomitant diseases and administered medicines which might increase the risk of complications. RESULTS In 35 patients (7.7%) a complication occurred in the form of pancreatitis (AP). A severe course was confirmed in 11 patients (31%). Cholelithiasis constituted approximately 2/3 of indications for ERCP. AP after ERCP was significantly more often observed in the group of patients aged under 40 (22.9% vs 8.6%; p<0.05). Narrow biliary ducts (3-8 mm) were the factor increasing the frequency of development of AP (25.9% vs 45%; p<0.05). Death occurred in 5 patients (1.1%), including 4 patients (0.96%) in the group without complications, and in 1 patient (2.85%) with complicated AP. CONCLUSIONS ERCP is a very valuable procedure in clinical treatment; however, it is burdened with the risk of complications, such as AP, bleeding, or duodenal perforation. A group especially exposed to the risk of complications in the form of AP are young patients aged under 40 with a narrow CBD.

Abstract
AIM: To study the effect of hydrogen sulfide (H2S) on severe acute pancreatitis (SAP) in a rat model.
METHODS: Sprague-Dawley (SD) rats were administered an intraperitoneal injection of saline containing 20% L-Arg (250 mg/100 g) hourly for over 2 h to induce SAP. The rats were treated with DL-propargylglycine (PAG, 50 mg/kg) or different dosages of NaHS (5 mg/kg, 10 mg/kg, 20 mg/kg or 100 mg/kg). PAG or NaHS was administered 1 h before induction of pancreatitis. Rats were sacrificed 24 h after the last L-Arg injection. Blood and pancreas tissues were collected.
RESULTS: The H2S and cystathionine-γ-lyase mRNA levels in SAP rats were significantly lower than those in the control group, and treatment with PAG further reduced the H2S level. Nevertheless, H2S was significantly increased after NaHS administration compared with the SAP group, and the degree of upregulation was associated with the NaHS dosage. NaHS reduced the levels of plasma amylase, interleukin-6 and myeloperoxidase in pancreatic tissue. NaHS suppressed the degradation of IκBα and the activity of nuclear factor-κB, as well as the phosphorylation of PI3K/AKT.
CONCLUSION: H2S plays an anti-inflammatory role in SAP in vivo.

Abstract
INTRODUCTION In acute pancreatitis, enteral nutrition (EN) reduces the rate of complications, such as infected pancreatic necrosis, organ failure, and mortality, as compared to parenteral nutrition (PN). Starting EN within 24 h of admission might further reduce complications. METHODS A literature search for trials of EN in acute pancreatitis was performed. Authors of eligible trials were requested to provide the data of all patients in the EN-arm of their trials. A meta-analysis of individual patient data was performed. The cohort of patients with EN was divided into patients receiving EN within 24 h or after 24 h of admission. Multivariable logistic regression, adjusting for predicted disease severity and trial, was used to study the effect of timing of EN on a composite endpoint of infected pancreatic necrosis, organ failure, or mortality. RESULTS Observational data from 165 individuals from 8 randomised trials were obtained; 100 patients with EN within 24 h and 65 patients with EN after 24 h of admission. In the multivariable model, EN started within 24 h of admission compared to EN started after 24 h of admission, reduced the composite endpoint from 45% to 19% (adjusted odds ratio [OR] of 0.44; 95% confidence interval [CI] 0.20-0.96). Within the composite endpoint, organ failure was reduced from 42% to 16% (adjusted OR 0.42; 95% CI 0.19-0.94). CONCLUSIONS In this meta-analysis of observational data from individuals with acute pancreatitis, starting EN within 24 h after hospital admission, compared with after 24 h, was associated with a reduction in complications.

Abstract
Efficacy of a new method of intraoperative regional sympathetic blockade of splanchnic nerves was estimated, basing on the results of surgical treatment of 3134 patients, suffering gastric cancer. While comparing the immediate results of surgical interventions there was established, that the risk of postoperative pancreatitis occurrence (lethality) is dependent on the kind of operation performed and its traumaticity. The risk of postoperative pancreonecrosis occurrence (lethality) lowering after standard surgical and combined intervention, after gastric surgery with pancreatic resection was promoted by application of a spiritus-novocaine blockade with the objective to suppress sympathetic reflexes as an element of anesthesia intraoperatively and in early postoperative period.

Abstract
The role of adenosine A3 receptors and their distribution in the gastrointestinal tract have been widely investigated. Most of the reports discuss their role in intestinal inflammations. However, the role of adenosine A3 receptor agonist in pancreatitis has not been well established. The aim of this study is [corrected] to evaluate the effects of the adenosine A3 receptor agonist on the course of sodium taurocholate-induced experimental acute pancreatitis (EAP). The experiments were performed on 80 male Wistar rats, 58 of which survived, subdivided into 3 groups: C--control rats, I--EAP group, and II--EAP group treated with the adenosine A3 receptor agonist IB-MECA (1-deoxy-1-6[[(3-iodophenyl) methyl]amino]-9H-purin-9-yl)-N-methyl-B-D-ribofuronamide at a dose of 0.75 mg/kg b.w. i.p. at 48, 24, 12 and 1 h before and 1 h after the injection of 5% sodium taurocholate solution into the biliary-pancreatic duct. Serum for α-amylase and lipase determinations and tissue samples for morphological examinations were collected at 2, 6, and 24 h of the experiment. In the IB-MECA group, α-amylase activity was decreased with statistically high significance compared to group I. The activity of lipase was not significantly different among the experimental groups but higher than in the control group. The administration of IB-MECA attenuated the histological parameters of inflammation as compared to untreated animals. The use of A3 receptor agonist IB-MECA attenuates EAP. Our findings suggest that stimulation of adenosine A3 receptors plays a positive role in the sodium taurocholate-induced EAP in rats.

Abstract
The efficacy of the medicamentous prophylaxis of the acute postoperative pancreatitis (APP) was estimated in 594 patients. They all were divided into 3 groups: 1st was treated with octreotide, 2nd - with octreotide-depo, 3rd - with 5-ftoruracil and dalargin. Patients of the 3rd group showed the highest levels of α-amylase in both blood and drainage fluid during the early postoperative period. The frequency and severity of postoperative complication rates were the lowest in those patients, who received octreotide-depo and was 3,06%; whereas among patients of the 2nd group it was 16,8% and among those, who were treated with 5-ftoruracil and dalargin, it was 22,4%. The destructive forms of pancreatitis were registered in 2nd and 3rd groups in 1 and 3 patients, respectively. Intraabdominal abscesses were registered in 1 patient of the 1st and 6 patients of the 3rd group, respectively. The lethality rate was 0.9% in the 1st group; 1.02% in the 2nd and 1.8% in the 3rd group. The use of somatostatine analogues in the prophylaxis of postoperative complications proved to decrease overall complications' rate and, first of all, the rate of postoperative destructive pancreatitis. The use of the prolonged forms of somatostatine analogues, i.e., octreotide depo 10 mg is considered to be highly effective.

Abstract
BACKGROUND Severe acute pancreatitis (SAP) is characterized by fatal pathogenic conditions and a high mortality. It is important to study SAP complicated with multiple organ injury. In this study we compared the protective effects of three traditional Chinese medicines (Ligustrazine, Kakonein and Panax Notoginsenoside) on the small intestine and immune organs (thymus, spleen and lymph nodes) of rats with SAP and explored their mechanism of action. METHODS One hundred forty-four rats with SAP were randomly divided into model control, Ligustrazine-treated, Kakonein-treated, and Panax Notoginsenoside-treated groups (n=36 per group). Another 36 normal rats comprised the sham-operated group. According to the different time points after operation, the experimental rats in each group were subdivided into 3-, 6- and 12-hour subgroups (n=12). At various time points after operation, the mortality rate of rats and pathological changes in the small intestine and immune organs were recorded and the serum amylase levels were measured. RESULTS Compared to the model control groups, the mortality rates in all treated groups declined and the pathological changes in the small intestine and immune tissues were relieved to different degrees. The serum amylase levels in the three treated groups were significantly lower than those in the model control group at 12 hours. The pathological severity scores for the small intestinal mucosa, thymus and spleen (at 3 and 12 hours) in the Ligustrazine-treated group, for the thymus (at 3 and 12 hours) and spleen (at 3 and 6 hours) in the Kakonein-treated group, and for the thymus (at 3 hours) and spleen (at 3 hours) in the Panax Notoginsenoside-treated group were significantly lower than those in the model control group. The pathological severity scores of the small intestinal mucosa (at 6 and 12 hours) and thymus (at 6 hours) in the Ligustrazine-treated group were significantly lower than those in the Kakonein- and Panax Notoginsenoside-treated groups. CONCLUSIONS All the three traditional Chinese drugs significantly alleviated the pathological changes in the small intestine and immune organs of SAP rats. Ligustrazine was the most effective one among them.

Abstract
Acute pancreatitis is rare in pregnancy but it is associated with increased incidence of maternal and fetal mortality. It should be considered in the differential diagnosis of upper quadrant abdominal pain with or without nausea and vomiting. The commonest identified causes of acute pancreatitis in pregnancy are gallstones, alcohol and hypertriglyceridemia. The main laboratory finding is increased amylase activity. Appropriate investigations include ultrasound of the right upper quadrant and measurement of serum triglycerides and ionized calcium. Management of gallstone pancreatitis is controversial, although laparoscopic cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) are often used and may be associated with lower complication rates. In hypertriglyceridemia-induced acute pancreatitis ω-3 fatty acids and even therapeutic plasma exchange can be used. We also discuss preventive measures.

Abstract
Significant literature on the management of acute severe acute pancreatitis has emerged in recent years. The new information ranges from data on newer single or multiparameter severity assessment tools and classification systems to therapeutic modalities. However, a few basic issues-the ideal severity assessment modality, volume of intravenous fluids required in the first 48 to 72 h, and the role of prophylactic antibiotics-are still not clear and are subject to controversy. The International Working Group has devised the Revised Atlanta Classification, which will be published soon. This new classification is eagerly awaited worldwide, and hopefully clarifies many of the problems of the original Atlanta Classification. In this article, we discuss the developments that have arisen in the past 2 to 3 years concerning the classification, prognostication, and early management of severe acute pancreatitis.

Abstract
PURPOSE OF REVIEW Lipoprotein apheresis is being performed with increasing frequency, but better data collection and recording of clinical outcomes are needed. Setting up registries would facilitate this process. RECENT FINDINGS This review appraises recent articles that discuss the need for national registries and requirements for setting them up, the efficacy of lipoprotein apheresis in homozygous familial hypercholesterolaemia and patients with coronary disease secondary to raised levels of lipoprotein (a), and its role in the management of acute pancreatitis secondary to severe hypertriglyceridaemia. SUMMARY Lipoprotein apheresis seems to be going through a growth spurt, presumably reflecting better implementation of treatment guidelines or a broadening of indications for its use.

Abstract
Melatonin exhibits a wide variety of biological effects, including antioxidant and anti-inflammatory functions. Its antioxidant role impedes the etiopathogenesis of pancreatitis, but little is known about the signaling pathway of melatonin in the induction of antioxidant enzymes in acute pancreatitis (AP). The aim of this study was to determine whether melatonin could prevent cerulein-induced AP through nuclear factor erythroid 2-related factor 2 (Nrf2) and curtail inflammation by inhibition of NF-kappaB. AP was induced by two intraperitoneal (i.p.) injections of cerulein at 2 h intervals (50 microg/kg) in Sprague-Dawley rats. Melatonin (10 or 50 mg/kg/daily, i.p.) was administered 24 h before each injection of cerulein. The rats were killed 12 h after the last injection. Acinar cell degeneration, pancreatic edema, and inflammatory infiltration were significantly different in cerulein- and melatonin-treated rats. Melatonin significantly reduced amylase, lipase, MPO, and MDA levels, and increased antioxidant enzyme activities including SOD and GPx, which were decreased in AP (P < 0.05). Melatonin increased the expression of NQO1, HO-1, and SOD2 when compared with the cerulein-induced AP group (P < 0.05). In addition, melatonin increased Nrf2 expression, and reduced expressions of tumor necrosis factor-alpha, IL-1beta, IL-6, IL-8, and iNOS. The elevated nuclear binding of NF-kappaB in the cerulein-induced pancreatitis group was inhibited by melatonin. These results show that melatonin increases antioxidant enzymes and Nrf2 expression, and limits inflammatory mediators in cerulein-induced AP. It is proposed that melatonin may play an important role in oxidative stress via the Nrf2 pathway in parallel with reduction of inflammation by NF-kappaB inhibition.

Abstract
Approximately 20% of patients with acute pancreatitis develop pancreatic necrosis, which is often complicated by secondary infection. This is a serious condition, which continues to have a death-rate of between 10% and 40% despite concerted efforts. Traditionally, management was aggressive, with open necrosectomy, but this has developed into an approach of watchful waiting, attempting to postpone surgery until necrosis can be better controlled. More recently, video-assisted retroperitoneal debridement (VARD) has become available as a minimally invasive surgical option, with the theoretical advantage of causing less trauma to these already severely ill patients. Van Santvoort et al. conducted a multicentre randomized study comparing open necrosectomy with a step-up approach consisting of percutaneous drainage followed, if necessary, by VARD. They show that a composite endpoint, consisting of major morbidity factors and mortality, occurs significantly less in the step-up approach, i.e. 40% versus 69%. Interestingly, 35% of patients in the step-up approach group were adequately treated without the need of a subsequent VARD procedure. An important subsidiary effect of this study is that care for patients with acute pancreatitis has been significantly improved, as a result of cooperation between academic and community hospitals within the Dutch Acute Pancreatitis Study Group: an expert team of experienced surgeons, specialists in gastroenterology and hepatology, and radiologists provide advice within 24 hours. Those patients in whom the disease has a complicated course can be transferred to specialised centres of treatment.

Abstract
Infected pancreatic necrosis (IPN) is one of the main causes of mortality in patients with acute pancreatitis (AP). The choice of antibiotic therapy in AP should be based on penetration of the drug in the pancreas and the degree of coverage provided against the typical bacterial flora produced in IPN. Drugs such as imipenem, ciprofloxacin and metronidazole have been widely studied and seem to be ideal in the treatment of INP. Clinical practice guidelines recommend a carbapenem agent as the initial empirical treatment. When Gram-positive pathogens are isolated in pancreatic samples, vancomycin can be used alone or associated with a carbapenem. Currently, prophylactic antibiotic therapy for IPN is not supported by the scientific evidence, since both the best quality studies (double-blind) and the latest meta-analysis published have found no benefit of the use of this strategy.

Abstract
The management of infected peripancreatic or pancreatic necrosis in patients with severe pancreatitis has changed considerably in recent years. This review discusses the recent literature on prevention, detection, and management of infected necrosis. Though antibiotics, probiotics, and enteral nutrition have been tried to prevent infected necrosis, only enteral nutrition has consistently proven to be effective. Antibiotics and probiotics have not shown a consistent beneficial effect on outcome. Enteral nutrition reduced infectious complications and mortality in severe pancreatitis, compared with parenteral nutrition. The detection of infection of pancreatic necrosis is important for clinical decision making. Fine-needle aspiration may be used to confirm suspected infection, but if its results will not change clinical decisions, it should be omitted, as it may even introduce infection. Minimally invasive surgical, radiologic, or endoscopic intervention is increasingly being applied. In the absence of level 1 evidence, local expertise dictates which type of intervention is applied.

Abstract
BACKGROUND AND AIMS In addition to the effect of regulating adipocyte differentiation and insulin sensitivity, peroxisome proliferator activated receptor-gamma (PPAR-gamma) ligands also exhibit anti-inflammatory effect. However, the mechanisms concerning how PPAR-gamma ligands affect acute pancreatitis and pancreatitis-associated lung injury have not been fully elucidated. This study investigated the effect of rosiglitazone, a PPAR-gamma ligand, on acute pancreatitis and pancreatitis-associated lung injury in the rat pancreatitis model induced by sodium taurocholate. METHODS Acute pancreatitis was induced by retrograde infusion of 5% sodium taurocholate (1 mL/kg) into the bile-pancreatic duct. Rosiglitazone (6 mg/kg) was administered via the femoral vein 30 min prior to the infusion of sodium taurocholate. The severity of pancreatitis was evaluated by serum amylase level, myeloperoxidase activity, and pathology. Pancreatitis-associated lung injury was evaluated by myeloperoxidase activity, the magnitude of pulmonary edema and pathology. Intercellular adhesion molecule-1 (ICAM-1) and tumor necrosis factor-alpha mRNA expression were studied using reverse transcriptase polymerase chain reaction. ICAM-1 protein expression was studied using Western blot analysis. RESULTS Prophylactic administration of rosiglitazone attenuated (1) serum amylase level; (2) myeloperoxidase activity of pancreatic and pulmonary tissue; (3) expression of tumor necrosis factor-alpha and ICAM-1 in pancreas and lung; (4) pancreas and lung pathological damage. CONCLUSIONS Our study demonstrated that rosiglitazone exerts a protective effect against sodium taurocholate-induced pancreatic and pulmonary injury.

Abstract
The authors have performed 407 resections of the stomach for duodenal ulcers. In 9 cases the major duodenal papilla was found to be involved into the zone of ulcer destruction. It was noted that operations for "difficult" complicated ulcers of the duodenum with the involvement into the zone of destruction of the major duodenal papilla required a delicate surgical strategy directed to minimization of trauma and blockade of the main factors of the development of acute postoperative pancreatitis, the proximal duodenojejunoanastomosis being the operation of choice for "difficult" complicated ulcers of the duodenum.

Abstract
Zinc (Zn) consumption has increased in many populations either due to the increased intake of Zn-fortified foods as in the USA or in agricultural food stuffs as in some Indian states during the last decade. Its excessive intake has been reported to induce acute pancreatitis (AP) in many studies due to increase in oxidative stress that was further reported to cause Cu and Mg deficiencies. This led us to design a modified poultry egg (ME(Psi)) enriched with Cu and Mg along with other antioxidants, and its efficacy on Zn-induced AP was studied in male Wistar rats. In one set, the rats were fed on equacaloric semi-synthetic basal diet containing 20 mg Zn/kg diet (control, group I), and Zn-induced AP-I diet and AP-II diet containing 40 and 80 mg Zn/kg diet (groups II and III) for 180 days, respectively. In another set, the rats were initially fed on Zn-induced AP-I and AP-II diets for 90 days and then shifted to ME(Psi)-mixed Zn-induced AP-I and AP-II diets in groups IIME and IIIME for another 90 days. At the end of the experiment, data displayed increased serum and urinary Zn, Cu, and Mg levels in groups II and III rats, which were reduced and approached closer to control group I after ME(Psi) feeding in groups IIME and IIIME rats. Transmission electron microscopic studies of acinar cells revealed progressive dilation, vesicularization, and degeneration of endoplasmic reticulum (ER), and decrease in zymogen granules (ZG) in groups II and III rats in contrast to their curvilinear or concentric long parallel running cisternal profile of ER in control group I. The treatment of ME(Psi) helped in the restoration of the ER profile and ZG number, approaching closer to the control group I. The degree of recovery was dependent upon the degree of toxicity caused by the amount of Zn given in the diet. The results of this study suggest that ME(Psi)-mixed diet can protect the acinar cells from the deleterious effects of Zn by decreasing the oxidative stress.

Abstract
BACKGROUND/AIMS The incidence of acute pancreatitis varies from 5 to 80 per 100,000 inhabitants throughout the world. The most common cause of death in these patients is infection of pancreatic necrosis by enteric bacteria, spurring the discussion of whether or not prophylactic antibiotic administration could be a beneficial approach. We therefore analyzed randomized clinical trials, which form the basis of guidelines and recommendations on this topic. RESULTS One trial demonstrated that antibiotic prophylaxis reduces mortality, but the statistical design of this trial was questionable. Another important trial, showing an effect of antibiotic prophylaxis on the incidence of pancreatic sepsis, used the wrong statistical test to analyze their data. An analysis with the correct test could not confirm this effect. Three randomized clinical trials demonstrated that antibiotic prophylaxis in severe acute pancreatitis could reduce the incidence of extrapancreatic infections. Two trials showed a significant reduction of the overall infection rate; while in one of them peripancreatic and extrapancreatic infections alone were not significantly different. Two double blinded studies could not demonstrate a significant effect of antibiotic prophylaxis on pancreatic/peripancreatic infection, extrapancreatic infection or mortality. CONCLUSION Our analysis shows that some of the reported significant effects of prophylactic antibiotic treatment are either questionable or less clinically relevant. With regards to reduction in mortality and the incidence of infected pancreatic necrosis, no convincing evidence exists which supports the routine administration of prophylactic antibiotics in severe acute pancreatitis.

Abstract
OBJECTIVE Chronic pancreatitis, characterized by pancreatic exocrine tissue destruction with initial maintenance of islets, eventually leads to insulin-dependent diabetes in most patients. Mice deficient for the transcription factors E2F1 and E2F2 suffer from a chronic pancreatitis-like syndrome and become diabetic. Surprisingly, onset of diabetes can be prevented through bone marrow transplantation. The goal of the described studies was to determine the hematopoietic cell type responsible for maintaining islets and the associated mechanism of this protection. RESEARCH DESIGN AND METHODS Mouse models of acute and chronic pancreatitis, together with mice genetically deficient for macrophage production, were used to determine roles for macrophages in islet angiogenesis and maintenance. RESULTS We demonstrate that macrophages are essential for preventing endocrine cell loss and diabetes. Macrophages expressing matrix metalloproteinase-9 migrate to the deteriorating pancreas. E2f1/E2f2 mutant mice transplanted with wild-type, but not macrophage-deficient colony stimulating factor 1 receptor mutant (Csf1r(-/-)), bone marrow exhibit increased angiogenesis and proliferation within islets, coinciding with increased islet mass. A similar macrophage dependency for islet and islet vasculature maintenance is observed during caerulein-induced pancreatitis. CONCLUSIONS These findings demonstrate that macrophages promote islet angiogenesis and protect against islet loss during exocrine degeneration, could explain why most patients with chronic pancreatitis develop diabetes, and suggest an avenue for preventing pancreatitis-associated diabetes.

Abstract
Pancreatitis is a mild and self-limiting disease. Although severe forms such as acute necrotizing pancreatitis (ANP) are rare it is associated with significant mortality rate reported to be 30-70%. Probiotics are viable microbial dietary supplements when introduced in sufficient quantities can have beneficial effects. The physiological effects of probiotics include suppression of bacterial infections, production of some digestive enzymes and vitamins and reconstruction of normal intestinal microflora. In the present study, the aim was to investigate the role of probiotics on the DNA damage in the peripheral lymphocytes, in the exfoliated epithelial cells and lymphocytes of the peritoneal fluids and in the pancreatic acinar cells of ANP induced rats. DNA damage was determined by COMET assay. ANP was induced by intravenous infusion of cerulein and superimposed infusion glycodeoxycholic acid into biliopancreatic duct. Saccharomyces Boulardii was used as the probiotic agent. DNA damage in pancreatic acinar cells and exfoliated epithelial cells and the lymphocytes of the peritoneal fluids was significantly higher in pancreatitis group compared to the controls and probiotic treated groups (P<0.001). No significant difference was observed in the DNA damage between the groups in the peripheral lymphocytes. In conclusion; our results support that probiotic agent Saccharomyces Boulardii can diminish bacterial infections and offer health benefits in the therapy of pancreatitis.

Abstract
BACKGROUND AND AIM Octreotide is considered to reduce exocrine pancreatic secretion in acute hemorrhagic necrotizing pancreatitis decreasing pancreatic autodigestion. The aim of this study was to determine whether octreotide also has antioxidative effects in acute pancreatitis. Additionally time and dose of application were of interest. METHOD Ninety male Sprague-Dawley rats were randomized into six groups (n = 15). Group 1 underwent a laparotomy, and animals in groups 2-6 received intraductal glycodeoxycholic acid followed by intravenous cerulein. Groups 3 and 4 were injected with 0.5 mg octreotide, while groups 5 and 6 received continuous intravenous infusion of 0.05 mg octreotide/h for 10 h. Treatment was initiated 6 hours after induction of pancreatitis (IP) in groups 3 and 5, and 14 h after IP in groups 4 and 6. At 24 h after IP all animals were killed and each pancreas was analyzed histopathologically. In addition, levels of pancreatic lipid peroxidation protective enzymes glutathione-peroxidase (GSH-Px) and superoxide dismutase (SOD) as well as lipid peroxidation via thiobarbituric acid reactive substances (TBARS) were determined. RESULTS Early bolus application of octreotide reduced severity of histopathological changes in acute pancreatitis and decreased lipid peroxidation in pancreatic tissue samples; however, late bolus application and continuous intravenous infusion did not influence pancreatitis or lipid peroxidation. CONCLUSION Octreotide seems to have a dose- and time-dependent effect on histopathology and lipid peroxidation in a model of pancreatitis in rats.

Abstract
Apoptosis is a teleologically beneficial form of cell death in acute pancreatitis. Our previous work has demonstrated that induction of pancreatic acinar cell apoptosis by crambene protects mice against acute pancreatitis. However, little is known about how the induction of apoptosis reduces the severity of acute pancreatitis. Because the clearance of apoptotic cells might suppress inflammation and critically regulate immune responses, we postulate that clearance of apoptotic cells stimulates an anti-inflammatory response, which has a protective action against acute pancreatitis. To test this hypothesis, induction of apoptosis in acute pancreatitis in vivo and co-cultures of peritoneal resident macrophages with apoptotic acinar cells in vitro were used as experimental systems, testing expression of phagocytic receptors and levels of inflammatory mediators. Moreover, neutralizing anti-interleukin (IL)-10 monoclonal antibody (2.5 mg/kg) was used before the induction of apoptosis in acute pancreatitis, testing whether the protection from apoptosis induction would be removed. Our study showed that clearance of apoptotic acinar cells, which may occur essentially through the CD36-positive macrophage, stimulates the release of anti-inflammatory mediators like IL-10. IL-10 plays an important role in crambene-induced protection in acute pancreatitis. Thus, induction of pancreatic acinar cell apoptosis by crambene protects mice against acute pancreatitis via induction of anti-inflammatory pathways.

Abstract
The chronic experiments on dogs with a pancreatitis model showed that reamberin involved in a complex therapy is conductive to timely positive clinical and laboratory dynamics of disease, particularly to the correction of lipid-induced distress syndrome, and leads to a significant decreasing in the incidence of pancreonecrosis. The positive effect of vitamin E is manifested to a lower degree. The lipid-controlling effect of antioxidants is realized due to a decrease not only in lipid peroxidation rate, but in the phospholipase A2 activity as well.

Abstract
BACKGROUND Acute pancreatitis is a common complication of ERCP, occurring in up to 10% of cases. Chemoprevention of post-ERCP pancreatitis remains a debated issue. OBJECTIVE This study evaluated whether increased dosage of octreotide, a potent inhibitor of pancreatic secretion, could reduce the incidence of post-ERCP pancreatitis. DESIGN In a randomized, double-blind, placebo controlled trial, the effect of 500 microg octreotide, given 3 times daily subcutaneously starting 24 hours before the ERCP procedure, was compared with that of placebo in patients who underwent diagnostic and/or therapeutic ERCP. PATIENTS A total of 202 patients were included in the trial. The 2 groups were similar in regards to age, sex, indications for treatment, underlying diseases, and types of therapeutic procedures. Patients were clinically evaluated, and serum amylase levels were determined before ERCP and at 6 to 8 hours thereafter. Standardized criteria were used to diagnose and to grade the severity of post-ERCP pancreatitis. RESULTS The medication was discontinued because of an allergic reaction in 1 patient in the octreotide group. The incidence of post-ERCP pancreatitis was significantly lower in the octreotide group compared with the placebo group (2/10 [2%] vs 9/101 [8.9%], P = .03). All cases of acute pancreatitis were mild, except 2 (1 moderate and 1 severe) in the placebo group. CONCLUSIONS The results of this trial support the use of 24-hour prophylaxis with high dose of octreotide in the prevention of post-ERCP pancreatitis.

Abstract
OBJECTIVES Acute pancreatitis is associated with substantial alterations of the immunologic host response which has been claimed to promote remote organ dysfunction, septic complications, and mortality. Treatment with immunomodulating substances has been subject of few experimental studies with still conflicting results. METHODS We used the taurocholate-induced model of severe acute pancreatitis (SAP) in rats which were assigned to different treatment regimen: isotonic saline (SAP-S) for nontreated controls, recombinant rat interferon-gamma for immunostimulation (SAP-IFN-gamma), and FK506 for immunosuppression (SAP-FK506). Animals were killed after 3, 6, and 24 hours as well as 3 and 7 days, and parameters of local and systemic severity were assessed. RESULTS Treatment with IFN-gamma and FK506 attenuated the progression of intrapancreatic necrosis within the first 24 hours after pancreatitis induction along with a substantial reduction of subsequent neutrophil tissue infiltration as shown by decreased myeloperoxidase activity. Enhanced cell death by apoptosis during the postacute course was reduced in FK506-treated animals only. Pancreatic interleukin (IL) 1beta messenger RNA up-regulation occurred early and was slightly suppressed in both treatment groups; tumor necrosis factor alpha (TNF-alpha) and IL-2 messenger RNA expression paralleled the onset of apoptosis and was markedly decreased in IFN-gamma- and FK506-treated rats. The 2 therapeutic regimens had similar effects on intrapancreatic and systemic IL-1beta and TNF-alpha protein release; however, the profiles of both cytokines were differently influenced. Whereas IFN-gamma and FK506 treatment lead to an enhanced intrapancreatic and systemic TNF-alpha protein release during the early course, IL-1beta concentrations were significantly reduced within the late intervals. Seven-day mortality was 44% in saline-, 29% in IFN-gamma-, and 25% in FK506-treated rats (P = not significant). CONCLUSIONS Severe acute pancreatitis is associated with early alterations of the immune response comprising overt T-cell activation and impaired monocyte/macrophage function alike. Targeting either immunologic derangement improves local pancreatic damage and systemic severity. However, because mortality was not improved, a therapeutic benefit of immunomodulating substances in clinical SAP remains to be defined.

Abstract
OBJECTIVE This study was designed to evaluate the effects of probiotics on the severity of experimental acute pancreatitis. DESIGN Experimental study. SETTING Experiments were done in a laboratory at Haydarpasa Numune Teaching and Research Hospital. SUBJECTS A total of 50 Wistar rats were randomly divided into five groups. INTERVENTIONS Group 1 was control group. Group 2 received an intraperitoneal injection of a 20% solution in 0.15 mol/l NaCL. Group 3 was injected NaCL and fed with probiotics. Acute pancreatitis was induced in rats by intrperitoneal injection of L-Arginine in groups 4 and 5. The rats in group 5 were treated with probiotics. The pancreas was removed for histologic examination. Evaluation of the pathologic changes was done by a new combined histopathologic grading scale. RESULTS The mean scores of fibrosis, acinar cell loss, oedema, parenchymal necrosis, mononuclear cells infiltration, polymorphonuclear leucocytes infiltration, ductal damage and atypical reactive regeneration in group 5 were significantly lower than group 4. CONCLUSIONS We demonstrated that enteral feedings with added probiotics can reduce the severity of acute pancreatitis. SPONSORSHIP None.

Abstract
Relapsing pancreatitis is characterized by repeated episodes of acute inflammation of the pancreas, with either a localized or a systemic organic response that may progress to chronic pancreatitis. Enteral jejunal feedings have been shown to be effective in the management of acute pancreatitis, but long-term use of jejunal feedings as treatment of relapsing pancreatitis has not been reported. We describe the case of a young patient treated with long-term jejunal feedings to induce remission and prevent recurrence of acute relapsing pancreatitis. An 18-year-old Hispanic man had well-documented recurrent episodes of acute pancreatitis. Multiple studies were performed as part of the diagnostic workup of the patient's relapsing pancreatitis, including endoscopic ultrasound, endoscopic retrograde cholangiopancreatography with biliary sphincterotomy, and laparoscopic cholecystectomy. Despite medical therapy, endoscopic and surgical procedures, the patient continued having episodes of pancreatitis on a monthly basis, with over 13 distinct documented episodes of pancreatitis during a 15-month period. A jejunostomy tube was inserted surgically, and long-term jejunal feedings were instituted, with excellent control of the patient's symptoms. There was only 1 episode of pancreatitis in the ensuing 24 months associated with the resumption of oral feedings and a weight gain of 20 pounds during this time period. Chronic jejunal feedings seem to be an effective alternative for treatment and prevention of acute relapsing pancreatitis. To our knowledge, this is the first report of long-term enteral feedings in acute relapsing pancreatitis.

Abstract
AIMS To avoid the progression from mild edematous acute pancreatitis (AP) to the severe necrotizing form, one therapeutic option is to improve pancreatic microcirculation and tissue oxygenation. The aim of the study was to evaluate the influence of improved rheology (isovolemic hemodilution) plus enhanced oxygen supply (bovine hemoglobin HBOC-301) on pancreatic microcirculation, tissue oxygenation and survival in severe acute experimental pancreatitis. METHODS Severe AP was induced in 39 pigs (25-30 kg BW) by stimulation with intravenous administration of cerulein plus a pressure- and volume-controlled 10-min intraductal infusion of glycodeoxycholic acid. Seventy-five minutes after induction of AP, animals were randomized and hemodiluted isovolemically (PAOP constant) with either 10% hydroxyethyl starch (HES) 200,000/0.5 plus HBOC-301 (+0.6 g/dl plasmatic hemoglobin; Oxyglobin, Biopure, Cambridge, Mass., USA), or 10% HES 200,000/0.5, or Ringer's solution to a hematocrit of 15%. Hemodynamics, oxygen transport parameters, pancreatic microcirculation and tissue oxygen tension were evaluated over 6 h. Then the abdomen was closed, animals were extubated and observed for 6 days. After that, the surviving animals were sacrificed and specimens were taken from the pancreas. The histopathologic findings were scored by two blinded pathologists who quantified acinar necrosis, fat necrosis, inflammation and edema. RESULTS Isovolemic hemodilution with HES plus HBOC-301 reduced mortality and preserved pancreatic microcirculation compared with Ringer's solution, but was not significantly different from hemodilution with HES alone. Only treatment with HES plus HBOC-301 normalized pancreatic tissue oxygen tension compared with IHD with HES or Ringer's solution alone. CONCLUSIONS IHD with HES plus HBOC-301 as a combination of rheologic and O(2)-delivering therapy may represent a novel therapeutic option for treatment of AP.

Abstract
Penetratin is a cationic cell-penetrating peptide that has been frequently used for the intracellular delivery of polar bioactive compounds. Recent studies have just revealed the major role of polyanionic membrane proteoglycans and cholesterol-enriched lipid rafts in the uptake of the peptide. Both proteoglycans and lipid-rafts influence inflammatory processes by binding a wide array of proinflammatory mediators; thus, we decided to analyze the effect of penetratin on in vitro and in vivo inflammatory responses. Our in vitro luciferase gene assays demonstrated that penetratin decreased transcriptional activity of nuclear factor-kappaB (NF-kappaB) in tumor necrosis factor (TNF)-stimulated L929 fibroblasts and lipopolysaccharide-activated RAW 264.7 macrophages. Penetratin also inhibited TNF-induced intercellular adhesion molecule-1 expression in human endothelial HMEC-1 cells. Exogenous heparan sulfate abolished the in vitro NF-kappaB inhibitory effects of the peptide. Uptake experiments showed that penetratin was internalized by all of the above-mentioned cell lines in vitro and rapidly entered the cells of the lung and pancreas in vivo. In an in vivo rat model of acute pancreatitis, a disease induced by elevated activities of stress-responsive transcription factors like NF-kappaB, pretreatment with only 2 mg/kg penetratin attenuated the severity of pancreatic inflammation by interfering with IkappaB degradation and subsequent nuclear import of NF-kappaB, inhibiting the expression of proinflammatory genes and improving the monitored laboratory and histological parameters of pancreatitis and associated oxidative stress.

Abstract
In recent years, a number of articles have been published on the treatment of acute pancreatitis in experimental models and most of them were published about animals with mild disease. However, it is difficult to translate these results into clinical practice. For example, infliximab, a monoclonal TNF antibody, was experimentally tested in rats and it was able to significantly reduce the pathologic score and serum amylase activity, and also alleviate alveolar edema and acute respiratory distress syndrome; no studies are available in clinical human acute pancreatitis. Another substance, such as interleukin 10, was efficacious in decreasing the severity and mortality of lethal pancreatitis in rats, but seems to have no effect on human severe acute pancreatitis. Thus, the main problem in acute pancreatitis, especially in the severe form of the disease, is the difficulty of planning clinical studies capable of giving hard statistically significant answers regarding the benefits of the various proposed therapeutic agents previously tested in experimental settings. According to the pathophysiology of acute pancreatitis, we may re-evaluate the efficacy of the drugs already available, such as gabexate mesilate, lexipafant and somatostatin which should be probably administered in a different manner. Of course, also in this case, we need large studies to test this hypothesis. Another great problem is prevention of the infection of pancreatic necrosis. A randomized study has been published to test the hypothesis that probiotics and specific fibres used as supplements in early enteral nutrition may be effective in reducing pancreatic sepsis and the number of surgical interventions. A study named PROPATRIA (Probiotic Prophylaxis in Patients with Predicted Severe Acute Pancreatitis) has been planned to give a more robust confirmation to the previous study. Furthermore, the open question of the prevention of the fungal infection of necrosis is still being debated. Finally, the prevention of pain relapse after oral feeding in patients with mild or severe acute pancreatitis should be explored. Even if some studies exist on this issue, the question of optimal treatment is still unanswered. As in other diseases, obtaining results when treating patients with acute pancreatitis is difficult and will take continuous small steps.

Abstract
Acute pancreatitis is a disease of increasing prevalence, unchanged mortality over many decades, and limited treatment strategies. Progress has been made in developing therapies that reduce the rate of endoscopic retrograde cholangiopancreatography (ERCP)-associated pancreatitis and in preventing infected pancreatic necrosis with intravenous carbapenems. Attempts at reducing pancreatic enzyme output or inhibiting the activity of digestive enzyme proteases have not yielded encouraging results - nor have anti-inflammatory strategies for the treatment of acute pancreatitis been found to be effective so far. Future therapeutic options that are presently being developed or under investigation attempt to restore pancreatic secretory function, interfere with inflammatory pathways in a more effective manner, or inhibit digestive enzyme proteases more selectively.

Abstract
An original drainage was used for preventing acute postoperative pancreatitis which had a construction providing preventive decompression of the pancreatic duct system acting on the pathogenetic mechanisms of its development, i.e. intraduct hypertension. The principal distinction of the proposed drainage construction is the duct system decompression with the saved physiological way of outflow of the pancreas secretion that eliminates the shortcomings of the external drainage. The drainage described was used in 6 patients after operations on the major duodenal papilla, cicatricial stricture of the papilla, choledocholithiasis. High clinical effectiveness of the method of the pancreatic duct system decompression is shown.

Abstract
OBJECTIVE To evaluate the capacity of enteral nutrition, in comparison with the total parenteral nutrition (TPN) plus antibiotic therapy, for avoiding pancreatic necrosis infection in the severe acute pancreatitis. METHODS In the period between October 1998 and September 2003, 87 patients met the inclusion criteria and took part in this research. Within the first week from their admission, 43 patients received TPN and 44 patients received total enteral nutrition (TEN). An adequate prophylactic antibiotic therapy was used in both groups. The severity of the manifestations was similar for both groups having a tomographic 'severity index' of 8 and an entry C-reactive protein of 208 and 203 mg/l, respectively. RESULTS The group that received TPN suffered an organ failure in 79% of the cases, while the percentage showed by the group that received TEN was 31%; 88 and 25% of the patients in each group requiring a surgical intervention, respectively (p < 0.001). There was decreased presence of pancreatic necrosis infection in the group of patients that was supplied with TEN (20%) than in the group receiving TPN, where it reached 74% (p < 0.001). The death rate was significantly higher among the patients who received TPN, (35%), while for the patients who received TEN it was only 5% (p < 0.001). CONCLUSION TEN could be used as a prophylactic therapy for infected pancreatic necrosis since it significantly diminished the necrosis infection as well as the mortality.
