Predictive value of serum apolipoprotein A-I in the organ failure of acute pancreatitis: a retrospective cohort study

Background Organ failure (OF) largely governs the outcomes and mortality in patients with acute pancreatitis (AP), but there is a lack of optimal prognostic biomarker for OF. This study is designed to investigate whether the serum apolipoprotein A-I (Apo A-I) level can predict OF in patients with AP. Methods A total of 424 patients with AP were reviewed in the study, and we finally got 228 patients eligible for analysis. Patients were divided into two groups based on serum Apo A-I level. Demographic information and clinical materials were retrospectively collected. The primary outcome was the occurrence of OF. Univariate and multivariate binary logistic regression were conducted to analyze the relationship between Apo A-I and OF. Additionally, we used receiver operating characteristic analysis to clarify the predictive value of serum Apo A-I level for OF and mortality. Results Ninety-two patients and 136 patients were included in Apo A-I low and non-low groups, respectively. The occurrence of OF was significantly different in the two groups (35.9 vs. 9.6%, p < 0.001). Moreover, serum Apo A-I level markedly decreased across disease severity based on the 2012 Revised Atlanta Classification of AP. The decrease of serum apolipoprotein A-I was an independent risk factor for organ failure (OR: 6.216, 95% CI: 2.610, 14.806, p < 0.001). The area under the curve of serum Apo A-I was 0.828 and 0.889 for OF and mortality of AP, respectively. Conclusions Serum Apo A-I level in the early stage of the disease has a high predictive value for OF of AP.

Early vs. late percutaneous catheter drainage of acute necrotic collections in patients with necrotizing pancreatitis.

It is recommended to drain the pancreatic fluid collections later in the course of the acute necrotizing pancreatitis (ANP). However, earlier drainage may be indicated. We compared early (≤ 2weeks) vs. late (3rd to 4th week) percutaneous catheter drainage (PCD) of acute necrotic collections (ANC). This retrospective study comprised ANP patients who underwent PCD of ANC. The diagnosis of ANP was based on revised Atlanta classification criteria and computed tomography performed between 5 and 7days of illness. Patients were divided into two groups [1st 2 weeks (group I) and 3rd-4th weeks (group II)] based on the interval between the onset of pain and insertion of catheter. The technical success, clinical success, complications, and clinical outcomes were compared between the two groups. One hundred forty-eight patients (74 in each group) were evaluated. The procedures were technically successful in all patients. The clinical success rate was 67.6% in group I vs. 77% in group II (p = 0.069). The incidence of complications was significantly higher in group I (n = 12, 16%) than group II (n = 4, 5.4%) (p = 0.034). These included 15 minor (11 in group I and 4 in group II) and one major complication (group I). Of the clinical outcomes, the need for surgery was significantly higher in group I than in group II (13 patients vs. 5 patients, p = 0.031). Early PCD is as technically successful as late PCD in the management of ANC. However, early PCD is associated with higher surgical rate and higher incidence of complications.

Metabolic-associated fatty liver disease is associated with acute pancreatitis with more severe course: Post hoc analysis of a prospectively collected international registry.

Non-alcoholic fatty liver disease (NAFLD) is a proven risk factor foracute pancreatitis (AP). However, NAFLD has recently been redefined as metabolic-associated fatty liver disease (MAFLD). In this post hoc analysis, we quantified the effect of MAFLD on the outcomes of AP. We identified our patients from the multicentric, prospective International Acute Pancreatitis Registry of the Hungarian Pancreatic Study Group. Next, we compared AP patients with and without MAFLD and the individual components of MAFLD regarding in-hospital mortality and AP severity based on the revised Atlanta classification. Lastly, we calculated odds ratios (ORs) with 95% confidence intervals (CIs) using multivariate logistic regression analysis. MAFLD had a high prevalence in AP, 39% (801/2053). MAFLD increased the odds of moderate-to-severe AP (OR=1.43, CI: 1.09-1.89). However, the odds of in-hospital mortality (OR=0.89, CI: 0.42-1.89) and severe AP (OR=1.70, CI: 0.97-3.01) were not higher in the MAFLD group. Out of the three diagnostic criteria of MAFLD, the highest odds of severe AP was in the group based on metabolic risk abnormalities (OR=2.68, CI: 1.39-5.09). In addition, the presence of one, two, and three diagnostic criteria dose-dependently increased the odds of moderate-to-severe AP (OR=1.23, CI: 0.88-1.70, OR=1.38, CI: 0.93-2.04, and OR=3.04, CI: 1.63-5.70, respectively) and severe AP (OR=1.13, CI: 0.54-2.27, OR=2.08, CI: 0.97-4.35, and OR=4.76, CI: 1.50-15.4, respectively). Furthermore, in patients with alcohol abuse and aged ≥60years, the effect of MAFLD became insignificant. MAFLD is associated with AP severity, which varies based on the components of its diagnostic criteria. Furthermore, MAFLD shows a dose-dependent effect on the outcomes of AP.

Presentation of Acute Pancreatitis in Sickle Cell Disease Patients: A Single Hospital Experience.

Sickle cell disease (SCD) is a haemoglobinopathy that leads to the formation of distorted sickle-shaped red blood cells that are prone to vaso-occlusion. This may lead to vaso-occlusive crises that may affect any organ. Acute pancreatitis (AP) in SCD patients may be mimicked by a vaso-occlusive crisis in the abdomen. The objective of this article is to analyse the clinical profiles of SCD patients with AP and understand the differences in the presentation of AP compared to an abdominal vaso-occlusive crisis and the difference between its presentation in SCD patients in comparison to other patients. Twenty-eight SCD patients who were diagnosed with AP during their admission to the paediatric department at a tertiary hospital between January 2012 and December 2020 were retrospectively studied. Patients aged older than 14 years were excluded. The data collected concerned: demographics, the clinical course and the hospital course. The diagnosis and severity protocols followed the revised Atlanta Criteria. The patients were aged with a mean of 9.61 years. There were 15 males and 13 females. Demographics were not significantly correlated to complication rates (P > 0.05). The mean duration of hospitalisation was 6.43 days. The most common clinical presentations were abdominal pain, fever, then vomiting and nausea. Three patients experienced complications and they were all cases of cholangitis (10.71%). There were no cases of pseudocysts, acute necrotic collections, pancreatic or peripancreatic necrosis or walled-off necroses. All of the cases of AP in SCD children were mild according to the revised Atlanta classification. Leucocytosis was present in 29.29% of patients and 17.8% of patients had high C-reactive proteins (CRPs). There was no significant correlation between leucocyte counts, CRP levels, serum or urinary amylase levels and complications (P > 0.05). All patients had haemoglobin (Hb) levels above 7 g/dL. The levels of sickle Hb ranged from 40 to 70 g/dL and reticulocyte counts averaged at 3.57%. Haematologic parameters were not significantly correlated with complication rates (P > 0.05). There were no recurrences. AP in SCD patients presented with classic signs and symptoms. There were no associations between demographics and complications. The levels of leucocytes, CRP counts and serum and urinary amylase were not correlated with complications. The level of Hb and sickle cell Hb was not associated with complication rates. Reticulocytes were slightly elevated in SCD patients with AP. More studies are needed to demarcate factors distinguishing AP in SCD from abdominal vaso-occlusive crises.

The mortality rate was signicantly higher in severe acute pancreatitis i.e. 57.89% as compared to mild and moderate acute pancreatitis (p value of 0.0001). The I.C.U admission rate in mild acute pancreatitis was 4.17% as compared to 100 % in severe acute pancreatitis (p value 0.0001). Statistically signicant difference was observed in serum procalcitonin levels (mean ±SD ng/dl) of mild, moderate and severe acute pancreatitis cases as per MCTSI scoring system (p value of 0.0001). Among the 98 cases, Conclusion: male to female ratio was 2.05:1. The most common cause of acute pancreatitis was ethanol abuse. The most prominent symptom was pain in the abdomen followed by vomiting. MCTSI fared well in predicting severity, mortality and I.C.U admissions in acute pancreatitis cases. The relationship of MCTSI score with serum procalcitonin in predicting severity was found to be signicant

EVALUATION OF PROGNOSTIC SIGNIFICANCE OF CRP, IONIC CALCIUM,AND SERUM ALBUMIN IN ACUTE PANCREATITIS

Introduction: Acute pancreatitis is defined as an inflammatory process of pancreas with possible peripancreatic tissue involvement and multi organ dysfunction syndrome with increasing mortality rate. In response to initial insult, acinar cells release proinflammatory cytokines, such as TNF a, IL-1, 2 and 6, and anti-inflammatory mediators such as IL-10 and IL-1 receptor antagonist. Acute pancreatitis is best diagnosed clinically in a patient presenting with 2 of the 3 following criteria.(1) Symptoms consistent with pancreatitis,(2) Serum lipase or amylase levels more than 3 times the laboratorys upper range of normal, and (3) Radiologic features suggestive of pancreatitis, usually using CECT. Usually, the first two criteria are present, and CECT is not required for diagnosis. Aims &amp; Objective: 1. To determine the prognosis of acute pancreatitis on the basis of quantitative value of CRP,SERUM ALBUMIN AND IONIC CALCIUM in admitted patients of HIMS on day of admission and after 48hours.2. To assess the severity of acute pancreatitis as mild,moderate,severe form(as per REVISED ATLANTA CLASSIFICATION 2013) and compare it with values of CRP,SERUM ALBUMIN AND IONIC CALCIUM. Methodology: The study will be conducted over a period of 18months (January 2021 to July 2022) in which all patients coming to General Surgery department at Hind Institute of Medical Sciences, Barabanki, UP with diagnosis of acute pancreatitis will be included. Result: We found that male population was higher than the female population. which was statistically significant. Higher number of patients had Pain in Abdomen Since 3 Days and patients were Alcoholic but this was statistically significant.Association of CRP Value with Day is statistically significant.Association of serum albumin value with Day is statistically significant. Association of Ionic Calcium value with Dayis statistically significant. This study shows that there is relation between se.CRP,se.Albumin and ionic calcium to assess the severity of Acute Pancreatitis.

P541 Diagnosis, management, and evolution of acute pancreatitis secondary to thiopurines in patients with Inflammatory Bowel Disease: an ENEIDA registry study.

Abstract Background Treatment with thiopurines in patients with Inflammatory Bowel Disease (IBD) may be associated with different adverse effects, including acute pancreatitis. Our aims were to evaluate the clinical presentation, severity and management of acute pancreatitis related to thiopurines in patients with IBD. Methods IBD patients with acute pancreatitis secondary to treatment with thiopurines for IBD were identified from the prospectively maintained ENEIDA registry of the Spanish Working Group on Crohn’s Disease and Ulcerative Colitis (GETECCU). We included those patients who met the Atlanta diagnostic criteria and had an imaging test that ruled out biliary origin of pancreatitis. Investigators at each participating centre provided additional information on pancreatitis clinical evolution and management. Results We included 290 patients with pancreatitis in 34 centres; 54% were women, 84% had Crohn’s disease and 56% were smokers. Five (1.7%) had had pancreatitis before, but no patient met criteria for chronic pancreatitis. The median age at pancreatitis was 36 years (IQR 27-50). In 94% of cases, pancreatitis occurred after the first thiopurine drug. Azathioprine was the thiopurine used in 97% of cases (median dose 2.3 mg/kg/day (IQR 2-2.5)), and 6% were treated with mercaptopurine (1.5 mg/kg/day (IQR 1-1.5)). Pancreatitis was diagnosed after a median of 23 days (IQR 14-35) since the start of the treatment with thiopurines. 81% required hospitalization for pancreatitis for a median of 5 days (IQR 4-7). Four (1.4%) were severe pancreatitis, 16 (5.5%) moderate, and the rest mild, according to the Atlanta classification. No epidemiological or treatment factors were associated with the severity of pancreatitis. Thiopurine was withdrawn in all patients upon diagnosis of pancreatitis. After 2 months (IQR 1-28) of pancreatitis, 16 patients (5.5%) received thiopurines again (5 the same, 11 a different thiopurine), suffering a new episode of pancreatitis in 12 (75%) after a median of 12 days (IQR 5-34). Pancreatitis occurred in all smokers that were treated again with thiopurines (n=7), compared to 5 of the 9 (56%) non-smokers or former smokers (p=0.04, RR 1.8; 95% CI 1.1-3.2). Conclusion Acute pancreatitis secondary to treatment with thiopurines is mild in most patients, usually appearing during the first month of treatment. The reintroduction of thiopurines, although feasible in some cases, is not recommended due to the high risk of developing a new pancreatitis, especially in smokers.

Contemporary Diagnostic Radiology 46(2):p 8, January 15, 2023. | DOI: 10.1097/01.CDR.0000905608.54137.e2

Imaging Features of Acute Pancreatitis and the Revised Atlanta Classification System

Acute pancreatitis is a major cause of hospital admissions in the United States, with the two primary causes being gallstones and alcohol.1 The Atlanta classification system is an international classification on the severity of acute pancreatitis. In 2012, deficiencies and outdated nomenclature were removed to make a revised system that take into account advancements in research and clinical management. The revised Atlanta classification system (RACS) in 2012 standardized the nomenclature for acute pancreatitis and local complications to facilitate effective communication between clinicians and radiologists alike. Older terms such as pancreatic abscess, phlegmon, acute pseudocyst, and fluid collection are no longer used, as they are vague and can be misleading.

The role of biomarkers in the early diagnosis of acute kidney injury associated with acute pancreatitis: Evidence from 582 cases.

One of the systemic complications of acute pancreatitis (AP) is acute kidney injury (AKI). AKI development in patients with AP increases mortality, morbidity, and the cost of treatment. Therefore, early diagnosis and prevention of AKI is important. The purpose of our study was to present biomarkers and case management of AKI developing in patients with AP. The participants of this retrospective study consisted of 582 patients who were followed up with the diagnosis of AP. Atlanta classification was used for the diagnosis and the identification of severity of AP. The laboratory values of patients at the time of first application to the emergency room were recorded. Blood tests were checked 48 h/l. Their blood tests were monitored daily until the day of discharge. Of the 582 patients who were admitted with the AP diagnosis, 344 were female. AKI was detected in 147 patients (25.2%) of the patients admitted with AP diagnosis. The mean age of patients developing AKI was higher than those who did not develop AKI. The albumin and calcium levels in patients developing AKI were significantly lower than the group without AKI. The C-reactive protein (CRP)/albumin and neutrophil/lymphocyte ratios were statistically significantly higher in the group with AKI than the group without AKI. The increase values in AST and ALT levels between the group with AKI and the group without AKI were not statistically significant. The mean leukocyte, CRP, procalcitonin levels, and immature granulocyte percentage (IG%) ratio were higher in patients with AKI in comparison to the patient group without AKI. The decrease in the lymphocyte, hematocrit, and platelet levels was higher in the patient group with AKI compared to the patient group without AKI. Urea and creatinine levels of the group with AKI at the time of admission were higher than the group without AKI. The clinical picture in 13 of the patients we followed up with AP diagnosis was mortal. The values of hematocrit, platelet, leukocyte, lymphocyte, albumin, CRP, CRP/albumin ratio, neutrophil/lymphocyte ration, IG%, procalcitonin, urea, and creatinine that were examined at the time of hospital admission can be useful biomarkers in predicting the development of AKI in patients with AP. In addition, accompanying diseases and age are among the factors affecting AKI development.

Anemia can predict organ failure in acute pancreatitis.

Acute pancreatitis (AP) is the leading hospital admission in Gastroenterology and has a variable clinical course. Identifying severity of AP patients in its early stages is of foremost importance to improve prognosis. The revised Atlanta Classification grades AP severity by the presence of organ failure and local complications.

Prediction of Prognosis Acute Pancreatitis with Inflammatory Markers and Patient Characteristics Compared to the Scoring System: Real-Life Data.

Acute pancreatitis (AP) is an inflammatory disease with a high morbidity and mortality rate. It is one of the most common causes of hospitalization among gastrointestinal system diseases. Inflammatory and other factors that predict the severity of AP are very important for patient management. This study will analyze the factors associated with the severity of AP. The sample consisted of 514 patients. Demographic characteristics, comorbid diseases, causes of AP, body mass index (BMI), tobacco use, blood at admission, amylase, lipase, leukocyte, neutrophil, lymphocyte, C-reactive protein (CRP), mean platelet volume, red cell distribution width, albumin, calcium, and CRP values at 48th h were recorded. The bedside index of severity in AP (BISAP), Ranson score, neutrophil-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) values was calculated and recorded. The relationship between these parameters and the severity of AP was analyzed according to the Atlanta classification. Participants had a mean age of 55±17.8 years. More than half the participants were women (n=272, 52.9%). Biliary causes were the most common etiological causes (n=299, 58.2%). Most participants had mild pancreatitis (n=416, 80.9%). The severity of AP was associated with tobacco use, high BMI, thrombocytosis, high NLR, high PLR, high 48th h CRP, hypoalbuminemia, hypocalcemia, aspartate aminotransferase/alanine aminotransferase ratio (AST/ALT ratio), and high Ranson and BISAP scores. Biochemical markers that give rapid results in the early period can provide information about the severity of AP. We may develop new scores by combining these parameters.

Red Cell Distribution Width and Ratio of Red Cell Distribution Width-to-Total Serum Calcium as Predictors of Outcome of Acute Pancreatitis.

Current severity assessment scores of acute pancreatitis (AP) include multiple variables, the results of which are available only after 48 h of admission. Red cell distribution width (RDW) and total serum calcium (TSC) are simple routine parameters related to inflammatory status and results of which are readily available. The aim of this study was to evaluate RDW and RDW: TSC within 24 h of hospital admission as predictors of outcome (severity and mortality) and intervention (medical/percutaneous drainage/surgical) required by patients of AP. All the patients diagnosed with AP at a tertiary care hospital were enrolled for the study. Values of RDW and TSC along with data regarding the treatment given were collected. Diagnosis and severity were defined according to the revised Atlanta classification 2012. Cutoff value for RDW (area under the receiver operating characteristic curve [AUROC]: 0.997; P = 0.000) to predict the severity of AP was 16.25% (sensitivity - 100% and specificity - 97.1%,) (sensitivity - 100% and specificity - 97.1%, positive predictive value - 92.31%, negative predictive value - 100%, and Youden Index - 0.971), while that of RDW:TSC (AUROC: 1; P = 0.000) was 2.42 (sensitivity - 100%; specificity - 100%, positive predictive value - 100%, negative predictive value - 100%, and Youden Index - 1.00). Similarly, the cutoff value for RDW (AUROC: 0.947; P = 0.000) to predict mortality in AP was 17.20% (sensitivity - 100%; specificity - 87.4%, positive predictive value - 38.89%, negative predictive value - 100%, and Youden Index - 0.874) and that of RDW-to-TSC ratio (AUROC: 0.975; P = 0.000) was 2.9 (sensitivity - 100%; specificity - 96.6%, positive predictive value - 70%, negative predictive value - 100%, and Youden Index - 0.966). Our study found that RDW and RDW: TSC were quick, convenient, economic, sensitive, and dependable prognostic predictors of severity and mortality in patients with AP.

Assessment of Severity of Pancreatitis by Computerized Tomography Using Revised Atlanta Classification and Comparison with BISAP Clinical Scoring System

Abstract Background: Untreated acute pancreatitis can have high morbidity and mortality. It is a serious gastrointestinal emergency. Its incidence is approximately 51.0 % and it can cause both local and systemic problems. The diagnosis usually involves laboratory tests like amylase and lipase as well as an ultrasound exam. The ideal imaging test is a contrast-enhanced CT scan. This study used scoring systems based on laboratory and radiological investigations to determine the clinical progression and outcome. Methods : Patients who were diagnosed with acute pancreatitis and in whom computed tomography was done were included. From the imaging findings, the category and subcategory of acute pancreatitis and types of fluid collections were described in these patients using the revised Atlanta classification. BISAP score was calculated in all these patients. The clinical outcome assessed in these patients is the duration of stay in the hospital, mortality, presence of persistent organ failure, the occurrence of infection and need for intervention. Finally, the correlation between the Revised Atlanta classification and BISAP score was analyzed and compared with clinical outcomes. Results: The analysis of the correlation between Revised Atlanta classification severity grade and BISAP score, among the n=57 patients with mild acute pancreatitis n=56, had BISAP score less than 3 and only one had BISAP score greater or equal to three. Among the n=25 patients graded as moderately severe acute pancreatitis, n=20 cases had a BISAP score of less than 3 and n=5 had BISAP score greater than or equal to three. Among the n=08 patients graded as severe acute pancreatitis, n=3 had a BISAP score of less than 3 and n=5 had BISAP score greater than or equal to three. Conclusion: Standardizing nomenclature and facilitating proper documentation of a variety of imaging abnormalities in acute pancreatitis is made possible by incorporating the new Atlanta categorization system into daily practice. We can triage, predict, and treat patients with acute pancreatitis with greater precision by integrating the new Atlanta classification with BISAP clinical grading, significantly improving medical care.

Early prediction of the severe course, survival, and ICU requirements in acute pancreatitis by artificial intelligence

ObjectiveTo evaluate the success of artificial intelligence for early prediction of severe course, survival, and intensive care unit(ICU) requirement in patients with acute pancreatitis(AP). MethodsRetrospectively, 1334 patients were included the study. Severity is determined according to the Revised Atlanta Classification(RAC). The success of machine learning(ML) method was evaluated by 13 simple demographic, clinical, etiologic, and laboratory features obtained on ER admission. Additionally, it was evaluated whether Balthazar-computerized tomography severity index(CTSI) at 48-h contributed to success. The dataset was split into two parts, 90% for ML(of which 70% for learning and 30% for testing) and 10% for validation and 5-fold stratified sampling has been utilized. Variable Importance was used in the selection of features during training phase of machine. The Gradient Boost Algorithm trained the machine by KNIME analytics platform. SMOTE has been applied to increase the minority classes for training. The combined effects of the measured features were examined by multivariate logistic regression analysis and reciever operating curve curves of the prediction and confidence of the target variables were obtained. ResultsAccuracy values for the early estimation of Atlanta severity score, ICU requirement, and survival were found as 88.20%, 98.25%, and 92.77% respectively. When Balthazar-CTSI score is used, results were found as 91.02%, 92.25%, and 98% respectively. ConclusionsThe ML method we used successfully predicted the severe course, ICU requirement and survival, with promising accuracy values of over 88%. If 48-h Balthazar-CTSI is included in the calculation, the severity score and survival rates increase even more.

İnsülin direncinin akut pankreatit şiddetine etkisi

Giriş ve Amaç: Akut pankreatit, pankreasın çeşitli nedenlere bağlı inflamasyonudur. Tüm dünyada önemli bir morbidite ve mortalite nedenidir. Metabolik sendromun önemli bir komponenti olan insülin direncinin inflamatuvar bir durum olması nedeniyle akut pankreatit hastalarında hastalık şiddetini etkileyebileceği düşünülmektedir. Çalışmamızda insülin direncinin akut pankreatit şiddeti ile ilişkisini araştırmayı ve diğer prognostik faktörlerle karşılaştırmayı amaçladık. Gereç ve Yöntem: Çalışmamızda klinikte akut pankreatit tanısı ile yatarak tedavi almış 84 hasta değerlendirmeye alınmıştır. Çalışmamız prospektif olarak dizayn edilmiştir. Akut pankreatit şiddetini belirlemek için hastaların laboratuvar ve görüntüleme bulguları kullanılarak Atlanta Sınıflandırması, 'Bedside Index of Severity in Acute Pancreatitis' skoru, Imrie skoru, Ranson skoru, Balthazar skoru belirlenmiştir. Hastalarda insülin direnci değerlendirilmesi için “İnsülin Direncinin Homeostatik Modeli Değerlendirmesi” skoru kullanılmıştır. Buna göre insülin direnci olan ve olmayan gruplar arasında hastalık şiddeti açısından fark olup olmadığı araştırılmıştır. Bulgular: Hastaların %45.2’si insülin direnci olan grupta yer aldı. Atlanta sınıflandırmasına göre 6 hasta (%7.1) şiddetli akut pankreatit olarak sınıflandırıldı. 4 hasta prerenal akut böbrek hasarı gelişmesi ve 2 hasta sepsis ve yoğun bakım gereksinimi olması nedeniyle şiddetli akut pankreatit olarak değerlendirildi. Hastalık şiddeti açısından yapılan Receiver Operating Characteristic analizinde Balthazar ve “Yatak başı akut pankreatit şiddet indeksi” skorunun hastaların prognozunu belirlemede güçlü oldukları görüldü (sırasıyla eğri altındaki alan; 0.955 ve 0.979). İnsülin direnci olan grubun “Yatak başı akut pankreatit şiddet indeksi” ve Balthazar skorları, insülin direnci olmayan grup ile karşılaştırıldığında istatistiksel olarak anlamlı farklılık saptandı (sırasıyla p = 0.019 ve p = 0.013). Sonuç: Çalışmamızda insülin direnci olan akut pankreatit hastalarında “Yatak başı akut pankreatit şiddet indeksi” ve Balthazar skorlarının yüksek saptanması, insülin direnci varlığının akut pankreatitin şiddetli seyretmesi yönünde prognostik bir faktör olarak kullanılabileceğini düşündürmektedir.

Endoscopic transpapillary drainage for walled-off pancreatic necrosis with complete main pancreatic duct disruption by metallic stent placement: A retrospective study.

Walled-off pancreatic necrosis (WOPN) is a serious complication of acute necrotizing pancreatitis (ANP) and may lead to disruption of the main pancreatic duct (MPD). Endoscopic passive transpapillary drainage (PTD) is an effective method for treating MPD disruptions. However, WOPN with complete MPD disruption is usually accompanied by disconnected pancreatic duct syndrome (DPDS), especially with infected necrosis. Endoscopic PTD with a fully covered self-expanding metallic stent (FCSEMS) and a plastic stent placement may have the potential for future application in treating complete MPD disruption in patients with WOPN. Patients with WOPN caused by ANP were classified according to the 2012 Atlanta classification and definition. In all patients, ERCP was performed 2 times. First, 3 patients were diagnosed with complete MPD disruption by ERCP. At the time of diagnosis, a plastic pancreatic stent (7Fr) was placed. Second, they underwent endoscopic PTD for WOPN with complete MPD disruption in which an FCSEMS and plastic stent placement were the only access routes to the necrotic cavity. The etiology of pancreatitis in these patients was of biliary, lipogenic, and alcoholic origin. The WOPN lesion size ranged from 6.5 to 10.2 cm in this study, and the type of WOPN was mixed in two cases and central in one case. The type of MPD disruption was complete in all three patients. The locations of disruption included the pancreatic body and head. The time from occurrence to the first ERCP was 18, 23, and 26 days, respectively. The main symptoms were abdominal pain, abdominal distention, fever, gastrointestinal obstruction, and/or weight loss. The three patients with symptomatic WOPN and MPD disruption underwent endoscopic PTD with FCSEMS and plastic pancreatic stent placement. Technical and therapeutic successes were achieved in 3/3 of patients. The mean time of stenting was 28-93 days. The clinical symptoms connected with WOPN and collection disappeared postoperatively in all three patients. During the follow-up period of 4-18 months, no patient developed collection recurrence or other complications, such as gastrointestinal bleeding or reinfection. All patients recovered uneventfully. In patients with WOPN with complete MPD disruption, endoscopic PTD with FCSEMSs and plastic stent placement may be an effective and safe method of treatment.

Nomenclature of Pancreatic Fluid Collections following Acute Pancreatitis: Need to Further Revise the Atlanta Classification System!

AbstractA better understanding of the disease pathophysiology, improved imaging modalities, and the development of minimally invasive interventions led to the revision of the Atlanta classification and new terminologies for the pancreatic fluid collections (PFCs) occurring in acute pancreatitis. Peripancreatic necrosis (PPN) or extra-pancreatic necrosis (EPN) has been reported as a distinct morphological entity with a better outcome than combined pancreatic and peripancreatic necrosis as well as pancreatic parenchymal necrosis alone and slightly worse than acute interstitial pancreatitis. In this news and views, we discuss a study that compared the morphological features and outcomes of endoscopic drainage of walled off necrotic collections developing after EPN alone with those developing after PN with or without EPN.

Supportive treatment during the periprocedural period of endoscopic treatment for pancreatic fluid collections: a critical review of current knowledge and future perspectives.

Pancreatic fluid collections (PFCs) commonly develop as complications of acute pancreatitis and ductal disruption due to chronic pancreatitis. In the revised Atlanta classification, PFCs were classified based on the presence of necrosis and duration following the onset of acute pancreatitis. Interventions are required in cases of symptomatic pancreatic pseudocysts or walled-off necrosis (WON). In the management of these PFCs, endoscopic ultrasound-guided transluminal drainage and subsequent direct endoscopic necrosectomy for WON are increasingly utilized as less invasive treatment modalities compared to surgical debridement. To date, researchers have focused predominantly on the technical aspects of endoscopic therapy for symptomatic PFCs. Given the poor physical condition of patients receiving endoscopic treatment for PFCs, systemic support may have a substantial impact on the short- and long-term outcomes of these patients. A multidisciplinary approach is required to improve the clinical outcomes of patients with infected PFCs and their associated comorbidities. However, non-interventional support during the periprocedural period of endoscopic treatment of PFCs has not been fully discussed, and there have been considerable variations in the selection of treatment options between endoscopists and centers. To address these unmet needs in the clinical management of PFCs and promote future research to improve the clinical outcomes, we conducted a review of the literature within a multicenter consortium of expert endoscopists with specific expertise in the endoscopic treatment of PFCs. In this review, we summarize the current evidence on non-interventional supportive care (e.g., continuous lavage, medications, nutritional support, and antimicrobials) and propose potential topics for future research.
