Insuficiencia pancreática endocrina transitoria secundaria a pancreatitis aguda necrotizante grave en una niña

Producto de una pancreatitis aguda (PA) puede haber una diabetes posterior o una hiperglicemia transitoria durante el episodio de PA. La incidencia de PA en edad pediátrica es de hasta 12,2 casos por 100 000 niños al año y sólo el 4 a 5% desarrollan luego diabetes. Con respecto a la hiperglicemia transitoria en niños, la información es escasa y no se ha hecho publicaciones al respecto en nuestro país. Se reporta el caso de una niña con hiperglicemia transitoria secundaria a una PA necrotizante grave. Es importante realizar un monitoreo constante de los niveles de glucosa y el tratamiento oportuno de la hiperglicemia en niños con PA ya que, al menos en adultos, se asocia a PA severa y mayor mortalidad.

As a result of acute pancreatitis (AP), there may be subsequent diabetes or transient hyperglycemia during the episode of AP. The incidence of AP in pediatric age is up to 12.2 cases per 100,000 children per year and only 4 to 5% later develop diabetes. Regarding transient hyperglycemia in children, information is scarce, and no publications have been made about it in our country. The case of a girl with transient hyperglycemia secondary to severe necrotizing AP is reported. It is important to constantly monitor glucose levels and timely manage hyperglycemia in children with AP since, at least in adults, it is associated with severe AP and higher mortality.

Pancreatitis aguda: Puntos clave. Revisión argumentativa de la literatura / Acute pancreatitis: Key points. Argumentative review of the literature

Introducción. La pancreatitis aguda es una condición gastrointestinal común que se asocia a una importante morbimortalidad. Se estima que su incidencia es de 34 por cada 100.000 habitantes, afecta principalmente a adultos a partir de la sexta década de la vida y en nuestra región es debida en la mayoría de los casos a cálculos biliares. Métodos. Se hizo una revisión de los aspectos fundamentales de esta patología, común y potencialmente mortal. Resultados. El diagnóstico requiere del hallazgo de manifestaciones clínicas, aumento de las enzimas pancreáticas en suero y, en ocasiones, el uso de imágenes diagnósticas. Se puede clasificar en leve, moderada y severa, lo cual es fundamental para determinar la necesidad de tratamiento y vigilancia en una unidad de cuidados intensivos. Conclusión. En la actualidad los pilares de manejo de la pancreatitis aguda son la terapia temprana con líquidos, tratamiento del dolor, inicio precoz de la vía oral y resolución del factor etiológico desencadenante. En presencia de complicaciones o un curso severo de enfermedad, pueden requerirse manejo antibiótico e intervenciones invasivas

Introduction. Acute pancreatitis is a common gastrointestinal condition that is associated with significant morbidity and mortality. It is estimated that its incidence is 34 per 100,000 inhabitants, it mainly affects adults from the sixth decade of life, and in our region, most of the cases are secondary to gallbladder stones. Methods. We present a review of the fundamental aspects of this disease, common and potentially fatal. Results. Diagnosis requires finding clinical manifestations, increased serum pancreatic enzymes, and sometimes the use of diagnostic imaging. It can be classified as mild, moderate and severe, which is essential to determine the need for treatment and monitoring in an intensive care unit. Conclusion. Currently, the pillars of management of acute pancreatitis are early fluid therapy, pain management, early oral food intake, and resolution of the etiology. In the presence of complications or a severe course of the disease, antibiotic management and invasive interventions may be required

Relationship between serum interleukin-6 and interleukin-10 levels and the clinical prognosis of severe acute pancreatitis / 中国基层医药

Objective:To investigate the relationship between serum interleukin-6 and interleukin-10 levels and clinical prognosis in patients with severe acute pancreatitis.Methods:Ninety-two patients with severe acute pancreatitis who received treatment in The Second People's Hospital of Liaocheng from August 2018 to July 2021 were included in this study. Serum interleukin (IL)-6 and IL-10 levels were detected. The Bedside Index of Severity in Acute Pancreatitis (BISAP) score was evaluated. Clinical interventions were performed. The relationship between serum IL-6 and IL-10 levels and the clinical prognosis of severe acute pancreatitis was investigated.Results:Serum IL-6 level [(103.75 ± 15.53) ng/L] was highest in patients who died. Serum IL-10 level [(97.33 ± 13.06) ng/L] was highest in patients with local complications. The highest number of patients with a prognostic outcome of death [26 (37.14%)] was found in patients with a BISAP score ≥ 3. Serum IL-6 level in patients with severe acute pancreatitis was positively correlated with the BISAP score ( r = 0.62, P < 0.05), and serum IL-6 level and BISAP score were negatively correlated with serum IL-10 level ( r = -0.57, -0.61, both P < 0.05). Conclusion:Increased or decreased serum IL-6 and IL-10 levels in patients with severe acute pancreatitis indicate that the patient's condition tends to worsen, and timely intervention according to serum IL-6 and IL-10 levels can improve the clinical prognosis of severe acute pancreatitis.

Establishment of prediction model for severe acute pancreatitis complicated with abdominal hypertension / 中华胰腺病杂志

Objective:To construct the prediction model of SAP complicated with intra-abdominal hypertension (IAH), and evaluate the prediction efficiency of the model.Methods:The clinical data of 322 SAP patients admitted to the emergency department of Cangzhou Hospital of Integrated Chinese and Western Medicine in Hebei Province from January 2017 to December 2021 were retrospectively analyzed. They were divided into IAH group ( n=153) and control group ( n=169) according to whether they had IAH complications or not. The clinical characteristics and laboratory test results of the two groups were compared. Multifactor logistic step-up regression was used to analyze the risk factors of SAP patients complicated with IAH. A nomogram model for predicting SAP complicated with IAH was established by using R software. The receiver operating characteristic curve (ROC) of the model was plotted, and the area under the curve (AUC) was calculated to evaluate its prediction efficiency. Calibration chart, Hosmer-Lemesshow test and decision curve analysis were used to evaluate the prediction accuracy and clinical application value of the model. The Bootstrap method was applied to verify the model internally. Results:In IAH group, cases with body mass index, CRP, procalcitonin (PCT), WBC, acute physiological and chronic health assessmentⅡ (APACHEⅡ) score, modified CT Severity Index score (MCTSI), incidence of complications (abdominal effusion, abdominal infection, gastrointestinal dysfunction, shock, multiple organ dysfunction syndrome), mechanical ventilation, the number of high-volume fluid reactivation (24 h≥4 L) were more than those in control group; serum albumin and serum calcium in IAH group were lower than those in control group, and the differences were statistically significant (all P value <0.05). Multivariate logistic regression analysis showed that serum albumin ( OR=0.815, 95% CI 0.710-0.937), CRP ( OR=1.005, 95% CI 1.002-1.008), MCTSI ( OR=2.043, 95% CI 1.695-2.463), complication of gastrointestinal dysfunction ( OR=4.179, 95% CI 2.170-8.049), and high-volume fluid resuscitation ( OR=4.265, 95% CI 2.269-8.015) were independent risk factors for IAH in SAP.The Nomogram prediction model was established using the five factors above as parameters, and the AUC value for predicting IAH complication was 0.886. The Hosmer-Lemesshow test showed a high consistency between the prediction results and the actual clinical observation results ( P=0.189). The results of decision curve analysis showed that the prediction probability of the model was between 10% and 85%, which could bring more benefits to patients. Conclusions:The early prediction model of SAP with concurrent IAH is successfully established, which can better predict the risk of SAP with concurrent IAH.

Clinical efficacy and outcome analysis of early abdominal paracentesis drainage for treating patients with severe acute pancreatitis / 中华胰腺病杂志

Objective:To analyse the clinical efficacy and outcome of early abdominal paracentesis drainage (APD) in the treatment of severe acute pancreatitis (SAP).Methods:The clinical data of 107 SAP patients with massive abdominal fluid in Shanghai General People Hospital from May 2017 to December 2021 were collected and analyzed. Patients were divided into APD group ( n=56) and NO-APD group ( n=51) according to whether they underwent APD or not within 3 days after admission. The APD group was then divided into abdominal compartment syndrome (ACS) subgroup ( n=29) and NO-ACS subgroup ( n=27) according to whether ACS had occurred or not at the time of puncture. Patients' general data, the duration of systemic inflammatory response (SIRS), length of ICU stay, the trends of intra-abdominal pressure and inflammatory indicators (white blood cell count and the content of C-reactive protein) within 1-3 days after admission, incidence of infection complication, step-up therapy, discharge or death were recorded. Results:The intra-abdominal pressure were 18.6±5.6mmHg , 13.7±4.2mmHg (1 mmHg=0.133 kpa) in APD group and NO-APD group, respectively. The intra-abdominal pressure of APD group was significantly higher than that of NO-APD group, and the difference was statistically significant ( P=0.000). Compared with NO-APD group, the duration of SIRS was significantly shortened in APD group [3(2, 4) days vs 4(3, 6) days, P=0.029]. On day 1, 2 and 3 after admission, the intra-abdominal pressure was 18.6±5.6 mmHg, 16.4±4.7 mmHg and 13.5±3.9 mmHg in APD group, and was 13.7±4.2 mmHg, 12.3±3.6 mmHg and 11.0±2.6 mmHg in NO-APD group, respectively. The intra-abdominal pressure of the APD group dropped faster than the NO-APD group ( P=0.004). The white blood cell count was (14.8±4.8), (10.5±4.5) and (9.0±3.8)×10 9/L in APD group, and was (14.2±5.4), (12.3±7.3), (11.7±5.3)×10 9/L in NO-APD group, respectively. Compared with the NO-APD group, the decrease rate of white blood cell count was faster in APD group ( P=0.006). The C-reactive protein content was (153.6±47.1), (150.4±10.5) and (108.8±49.4)mg/L in APD group, and were (174.8±31.1), (191.6±29.4) and (186.8±45.5)mg/L in NO-APD group . The content of C-reactive protein in APD group decreased significantly, while that in NO-APD group did not decrease. There was a significant difference between the two groups ( P=0.009). In the subgroup comparisons, the duration of SIRS in the ACS subgroup was significant longer than that in the NO-ACS subgroup [4(3, 5) days vs 2(1, 3)days, P=0.000]. Compared between the two groups and two subgroups respectively, there were no statistically significant differences on length of ICU stay, infection complication rate, advanced treatment rate and mortality. Conclusions:For SAP patients with abdominal fluid, APD in the early stage could shorten the duration of SIRS, decrease intra-abdominal pressure rapidly, improve inflammatory indicators, but could not improve the clinical outcome.

Observation on the clinical efficacy of continuous renal replacement therapy with adsorptive filter oXiris in the treatment of patients with severe acute pancreatitis / 中华胰腺病杂志

Objective:To evaluate the clinical efficacy of continuous renal replacement therapy (CRRT) with adsorptive filter oXiris in the treatment of severe acute pancreatitis (SAP).Methods:The clinical data of 5 SAP patients who received the treatment of absorptive filter oXiris in Department of Critical Care Medicine of Shanghai General Hospital from February 2021 to February 2022 were collected. The changes of inflammatory indicators, hemodynamics, acid-base balance indicators and organ function indicators were compared before and 24 h after treatment.Results:Before the treatment of oXiris, 3 patients had pancreatic necrotic infection, and all the five patients had systemic inflammatory response syndrome(SIRS), acute respiratory and circulatory failure and acute renal injury. At 24 h after the treatment with oXiris, the levels of inflammatory indicators such as white blood cell count [(13.4±5.0)×10 9/L vs (25.8±10.0)×10 9/L), CRP [(149.6±68.3)mg/L] vs (289.0±129.4)mg/L] and procalcitonin [3.7(1.4, 17.7)ng/ml vs 12.2(3.2, 62.9)ng/ml] in the blood samples from the patients were greatly decreased. Hemodynamics were obviously improved; heart rate [(107.4±9.5)bpm/min vs (143.4±9.7)bpm/min] was decreased, and the mean artery pressure [(87±5)mmHg vs (73±13)mmHg], 1 mmHg=0.133 kPa] tended to be stabilized. Metabolic acidosis was significantly improved; pH value (7.4±0.0 vs 7.2±0.1) and base excess (-2.1±2.5 vs -14.5±6.1) were increased, while lactic acid [(2.6±1.2)mmol/L vs (10.62±6.55)mmol/L] was decreased. Organ dysfunctions were improved; PaO 2/FiO 2 value (241.7±58.5 vs 115.9±53.6) was increased, while serum creatinine [(148.0±42.5)μmol/L vs (232.8±77.4)μmol/L], intra-abdominal pressure [(18.6±4.5)mmHg vs (24.2±4.0)]mmHg, modified Marshall score [3(3.0, 4.0) vs 6(5.5, 9.0)] and APACHEⅡ score (17.6±2.9 vs 26.0±5.2) were decreased. All the differences above were statistically significant (all P value <0.05). Conclusions:It is safe and feasible to treat SAP patients with CRRT by using oXiris in clinical practice, which may have the functions of clearing inflammatory mediators, stabilizing hemodynamics and acid-base balance and improving organ function.

Effect of T-lymphocyte and subpopulation counts on the prognosis of patients with severe acute pancreatitis / 中华胰腺病杂志

Objective:To investigate the effect of T-lymphocyte and subpopulation counts on the prognosis of severe acute pancreatitis (SAP) patients.Methods:The clinical data of 90 patients with SAP diagnosed at the Shanghai General Hospital between January 2019 and June 2022 were retrospectively analyzed, and the patients were divided into good prognosis and poor prognosis group according to whether they were diagnosed for 28 d. The general information of the patients was recorded, including blood-related immunological indicators within 24 h of diagnosis, including leukocytes, neutrophils, lymphocytes, monocytes, CD 3+ , CD 4+ , CD 8+ T-lymphocyte count and CD 4+ /CD 8+ T-lymphocyte ratio, IgG4 level; blood inflammation index procalcitonin, albumin level and APACHEⅡ score at admission; survival and complication status of patients at 28 d of diagnosis. Non-parametric Mann-Whitney U test was used to analyze the correlation between each index and the prognosis of the patients. The subject operating characteristic curve (ROC) of patients was plotted, and area under curve (AUC) was calculated to assess the value of CD 3+ and CD 4+ T-lymphocytes in predicting the prognosis of SAP. Results:The majority of SAP patients were male (65.6%). The main cause of SAP was gallstone (56.7%), followed by hyperlipidemia (35.6%). At 28 days after diagnosis, 85(94.4%) patients survived, and 39 of them were cured and included in the good prognosis group. Forty-six cases were complicated with infection, multiple organ dysfunction syndrome (MODS) and local pancreatic complications, and 5 cases (5.56%) died; and a total of 51 cases were included in the poor prognosis group. Compared with the good prognosis group, the number of CD 3+ T-lymphocytes [366(268, 498) cells /μl vs 709(578, 999) cells /μl], CD 4+ T-lymphocytes [209(120, 298) cells /μl vs 486(303, 548) cells /μl] and albumin level (33.9 g/L vs 35.9 g/L) within 24 hours in the poor prognosis group were significantly lower, while the level of procalcitonin (1.02 ng/ml vs 0.43 ng/ml) and APACHEⅡ score [7(4, 10) vs 5(3, 8)] were significantly increased, and all the differences were statistically significant (all P value <0.05). ROC curve analysis showed that the AUC values for CD 3+ and CD 4+ T-lymphocyte counts within 24 hours for predicting poor prognosis of SAP were 0.857 (95% CI 0.696-1.000) and 0.867 (95% CI 0.708-1.000), respectively. The cut-off values were 524 cells /μl and 301 cells /μl, the sensitivity were both 85.7%, and the specificity were 78.6% and 85.7%, respectively. Conclusions:The significant decrease of peripheral blood CD 3+ and CD 4+ T-lymphocyte count within 24 h of SAP diagnosis has a certain predictive value for the prognosis of patients with SAP.

LASSO regression based risk prediction model establishment for Klebsiella pneumonia infection in patients with severe acute pancreatitis / 中华胰腺病杂志

Objective:To construct a risk prediction model for infection with Klebsiella pneumonia (KP) for patients with severe acute pancreatitis (SAP).Methods:Retrospective analysis was done on the clinical data of 109 SAP patients who were admitted to Shanghai General Hospital, between March 2016 and December 2021. Patients were classified into infection group ( n=25) and non-infection group ( n=84) based on the presence or absence of KP infection, and the clinical characteristics of the two groups were compared. The least absolute shrinkage and selection operator (LASSO) algorithm was used to reduce the dimension of the variables with statistical significance in univariate analysis. A nomogram prediction model was created by incorporating the optimized features from the LASSO regression model into the multivariate logistic regression analysis. Receiver operating characteristic curve (ROC) was drawn and the area under curve (AUC) was calculated; and consistency index (C-index) were used to assess the prediction model's diagnostic ability. Results:A total of 25 strains of KP were isolated from 109 patients with SAP, of which 21(84.0%) had multi-drug resistance. 20 risk factors (SOFA score, APACHEⅡ score, Ranson score, MCTSI score, mechanical ventilation time, fasting time, duration of indwelling of the peritoneal drainage tube, duration of deep vein indwelling, number of invasive procedures, without or with surgical intervention, without or with endoscopic retrograde cholangiopancreatography (ERCP), types of high-level antibiotics used, digestion disorders, abnormalities in blood coagulation, metabolic acidosis, pancreatic necrosis, intra-abdominal hemorrhage, intra-abdominal hypertension, length of ICU stay and total length of hospital stay) were found to be associated with KP infection in SAP patients by univariate analysis. The four variables (APACHEⅡ score, duration of indwelling of the peritoneal drainage tube, types of high-level antibiotics used, and total length of hospital stay) were extracted after reduced by LASSO regression. These four variables were found to be risk factors for KP infection in SAP patients by multiple logistic regression analysis (all P value <0.05). Nomogram prediction model for KP infection in SAP was established based on the four variables above. The verification results of the model showed that the C-index of the model was 0.939, and the AUC was 0.939 (95% CI 0.888-0.991), indicating that the nomogram model had relatively accurate prediction ability. Conclusions:This prediction model establishes integrated the basic clinical data of patients, which could facilitate the risk prediction for KP infection in patients with SAP and thus help to formulate better therapeutic plans for patients.

Conclusion Current evidence shows that biliary etiology and alcoholic etiology are unique influencing factors for ANP in the Eastern population, while Ranson score is a unique influencing factor in the Western population.BMI and extent of necrosis ≥30% are unique influencing factors for IPN in the Eastern population, while alcoholic etiology is a unique influencing factor in the Western population.

Value of five scoring systems in predicting the severity of hyperlipidemic acute pancreatitis: A comparative analysis / 临床肝胆病杂志

Objective To investigate the value of pancreatitis activity scoring system (PASS) score, Bedside Index for Severity in Acute Pancreatitis (BISAP) score, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE-Ⅱ) score, harmless acute pancreatitis score (HAPS), and Ranson score in evaluating the severity and prognosis of hypertriglyceridemia acute pancreatitis (HTGAP). Methods A retrospective analysis was performed for the clinical data of 300 patients with HTGAP who were admitted to General Hospital of Ningxia Medical University from January 2016 to January 2022, and according to the disease severity, these patients were divided into mild acute pancreatitis (MAP) group, moderate-severe acute pancreatitis (MSAP) group, and severe acute pancreatitis (SAP) group. Clinical data and the above scores were compared between the three groups. The chi-square test was used for comparison of categorical data between groups; an analysis of variance was used for continuous data with homogeneity of variance, and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic (ROC) curve was plotted according to disease severity, and related indicators were compared in terms of the area under the ROC curve (AUC). Results There were significant differences between the three groups in PASS score ( F =219.351, P < 0.01), Ranson score ( χ 2 =83.084, P < 0.01), APACHE-Ⅱ score ( χ 2 =43.388, P < 0.01), and BISAP score ( χ 2 = 50.785, P < 0.01). Compared with the other four scoring systems in evaluating and predicting disease severity, PASS score had the highest sensitivity of 0.945 and the largest AUC of 0.963, followed by Ranson score with a sensitivity of 0.655 and an AUC of 0.819. Conclusion For patients with HTGAP, PASS score can more accurately assess the severity and prognosis of HTGAP patients and thus holds promise for clinical application.

Escalating strategies of surgical intervention for infected pancreatic necrosis / 中华消化外科杂志

The step-up approach is the most important modality in the treatment of infected pancreatic necrosis (IPN) and has been recommended by several national and international guidelines. Screening patients with low success rates of percutaneous drainage for timely treatment using the step-up approach and selecting appropriate escalation approach based on IPN staging are expected to improve the overall cure rate of IPN. The open debridement in the step-up approach should be carried out under reasonable indications and timing. When the patient's overall condition is poor and the condition of disease is complex, it is not necessary to adhere to a fixed treatment mode and choose a leapfrogging treatment strategy in a timely manner after thorough evaluation.When following the step-up approach in the treatment of IPN, endoscopic and surgical interventions are advocated in parallel, and escalating and leapfrogging strategies are promoted to establish an integrated, disease-centric, multidisciplinary treatment platform, with the aim of improving clinical prognosis. The authors review relevant literature and combine with team's treatment experience to explore the escalating strategies of surgical intervention for IPN, with a view to further improving the overall cure rate of IPN patients.

Research progress of respiratory virus infection associated acute necrotizing encephalopathy / 中华实用儿科临床杂志

Acute necrotizing encephalopathy (ANE) is a subtype of acute encephalopathy presented with disturbance of consciousness and symmetric bilateral thalamic necrosis in neuroradiology.Patients with ANE had a high mortality or severe neurological sequela.ANE usually secondary to virus infectious disease, in which influenza is a common etiology.During the 3 years of the worldwide pandemic of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection, ANE has become a severe complication and cause of death in children, which has aroused much concern.Here is a review of the research progress of epidemiology, pathogenesis, diagnosis, treatments and prognosis of ANE, in order to improve the knowledge of clinicians on this disease.

Alcoholic foamy degeneration: an unusual presentation of the alcoholic liver disease diagnosed on autopsy

ABSTRACT Alcoholic foamy degeneration (AFD) is an uncommon presentation of alcoholic liver disease (ALD) with characteristic histologic findings of foamy-looking hepatocytes due to the presence of abundant microvesicles of fat within the cytoplasm predominantly in perivenular and midzonal regions without inflammation and fibrosis. It is underdiagnosed as the patients quickly recover after alcoholic abstinence and are rarely caught on biopsies. AFD has better prognosis than alcoholic hepatitis, and the injury mechanism is different, warranting a different diagnosis. We present an uncommon case of AFD incidentally diagnosed during autopsy in a chronic alcoholic and diabetic man.

Rotura de Pseudoaneurisma tras Pancreatitis Aguda Necrotizante que debuta como Hemorragia Digestiva Alta por Fistulización del Duodeno

Presentamos el caso de un varón de 64 años quien, tras un primer episodio de pancreatitis aguda necrotizante, reingresa a los 20 días por cuadro de dolor epigástrico intenso y posteriormente episodio de hemorragia digestiva alta en forma de hematemesis y melenas con inestabilización hemodinámica. Se realiza en ese momento gastroscopia urgente objetivándose probable fistula gastrointestinal en bulbo duodenal con coágulo adherido sin sangrado activo en ese momento por lo que se realiza angio-TC urgente que revela colección peripancreática necrótica con presencia de sangrado activo en su interior, procedente de la arteria pancreatoduodenal. La arteriografía urgente identificó imagen compatible con pseudoaneurisma arterial dependiente de la rama de arteria pancreatoduodenal, que fue embolizada con éxito. Desgraciadamente el paciente falleció en las horas posteriores, como consecuencia de un shock séptico secundario a colección pancreática infectada.

We present the case of a 64-year-old man who, after a first episode of acute pancreatitis, was readmitted 20 days later due to severe epigastric pain and later an episode of upper gastrointestinal bleeding in the form of hematemesis and melena with hemodynamic instability. An urgent gastroscopy was performed at that time, revealing a probable gastrointestinal fistula in the duodenal bulb with an adherent clot without active bleeding at that time, so an urgent CT angiography was performed that revealed a necrotic peripancreatic collection with the presence of active bleeding inside from the pancreatoduodenal artery. Urgent arteriography identified an image compatible with arterial pseudoaneurysm dependent on the pancreaticoduodenal artery branch, which was successfully embolized. Unfortunately, the patient died a few hours later as a result of septic shock secondary to an infected pancreatic collection.

Caracterización de pacientes con pancreatitis aguda en una unidad de cuidados intensivos polivalente / Characterization of patients with Acute Pancreatitis in the multipurpose intensive care unit

RESUMEN Introducción: La pancreatitis es la inflamación del páncreas exocrino, resultado del daño a las células acinares. Sus características clínicas principales son el dolor abdominal y la elevación de los niveles séricos de amilasa y lipasa. La evolución es muy variable, desde una recuperación completa de un primer episodio, hasta una enfermedad crónica debilitante, o la muerte. Objetivos: Caracterizar a los pacientes ingresados en la unidad de cuidados intensivos, con el diagnóstico de pancreatitis aguda y evaluarlos según los criterios de gravedad. Métodos: Se realizó un estudio descriptivo en el que se revisaron 46 historias clínicas de pacientes ingresados con diagnóstico de pancreatitis aguda en la unidad de terapia intensiva polivalente, desde enero del 2014 a diciembre del 2019. Se confeccionó una base de datos con las variables edad, etiología, complicaciones, letalidad y la aplicación de escalas de Ranson, APACHE II y Balthazar-Hill, para evaluar evolutivamente la gravedad y pronóstico. Se hizo un análisis de frecuencias de dichas variables. Resultados: La edad de mayor incidencia correspondió a los grupos menores de 61 años, con predominio del sexo masculino. La causa más frecuente fue la litiasis vesicular y el alcoholismo, para un 43,4 % y 34,7 % respectivamente. El 47,8 % presentó la forma leve de la enfermedad. La letalidad fue del 21,7 %. Conclusiones: Son más frecuentes las formas graves de la enfermedad; la insuficiencia renal aguda y la insuficiencia respiratoria aguda son las complicaciones más representativas.

ABSTRACT Introduction: Pancreatitis is the inflammation of the exocrine pancreas, as a result of damage to the acinar cells. Its main clinical features are abdominal pain and elevated serum levels of amylase and lipase. The evolution is very variable, from a complete recovery from a first episode, to a debilitating chronic disease, or death. Objectives: To characterize patients admitted to the intensive care unit with a diagnosis of acute pancreatitis and to evaluate them according to severity criteria. Methods: A descriptive study was carried out in which 46 medical records of patients admitted with a diagnosis of acute pancreatitis in the multipurpose intensive care unit were reviewed, from January 2014 to December 2019. A database was created with the variables age, etiology, complications, lethality and the application of the Ranson, APACHE II and Balthazar-Hill scales, to evaluate severity and prognosis. An analysis of the frequencies of these variables was carried out. Results: The age with the highest incidence corresponded to groups under 61 years of age, with a predominance of males. The most frequent cause was gallstones and alcoholism, for 43.4 % and 34.7 % respectively. 47.8 % presented the mild form of the disease. The lethality was 21.7 %. Conclusions: Severe forms of the disease are more frequent; acute renal failure and acute respiratory failure are the most representative complications.

Clinical efficacy of laparoscopic surgery for infected pancreatic necrosis in subgastric approach / 中华胰腺病杂志

Objective:To investigate the technical key points and clinical effects of laparoscopic surgery using the subgastric approach for infected pancreatic necrosis (IPN).Methods:From October 2020 to October 2021, The clinical data of 6 patients with IPN after severe acute pancreatitis (SAP) undergoing laparoscopic surgery using the subgastric approach at First Hospital and Second Hospital of Hebei Medical University was retrospectively analyzed. Parameters in this report included the operation time, estimated blood loss, and the patient's vital signs, inflammatory marker CRP, and WBC before operation and postoperative 24 h, 3 d, and 1 w, and postoperative complications including pancreatic leakage, organ failure, bleeding, and abdominal infection and incision infection. Follow-up after surgery was completed in outpatient checkups and long-term complications were recorded.Results:There were 4 male and 2 female patients. The median age of the 6 patients was 50 (43.5, 56.5) years. Laparoscopic debridement surgery using the subgastric approach was successfully completed in all the patients and no reoperation was needed. The median operation time was 65 (52.5, 85) min; the median estimated blood loss was 20 (25, 37.5) ml. Median APACHEⅡ score one day before surgery was 11.5 (10.25, 12.75) and the median MCTSI score at initial admission was 8 (7, 8). The inflammatory parameters including CRP, WBC, and neutrophil count on postoperative day 3 and 1w were significantly lower than those before surgery, and all the differences were statistically significant (all P value <0.05). One patient had a postoperative pancreatic fistula and was alleviated after ERCP with pancreatic stent implantation. Another patient had a incision infection after surgery and recovered after complete surgical drainage of the abdominal wall incision. No patients had complications such as heart, lung, and kidney failure, abdominal hemorrhage and infection. During the follow-up, 5 of 6 patients had no newly-occurred diabetes, except one patient who had diabetes before the operation. None of the 6 patients had recurrent IPN. Conclusions:Laparoscopic surgery using the subgastric approach for infected IPN in lesser omental sac is safe and feasible.

Prognostic significance of BISAP combined with intra-abdominal pressure measurement in acute pancreatitis / 中华普通外科杂志

Objective:To investigate the predictive value of intra-abdominal pressure (IAP) combined with bedside index for severity in acute pancreatitis (BISAP) score on the severity and prognosis of acute pancreatitis (AP).Methods:In this retrospective study, 204 AP patients admitted to the Department of ICU, Second Hospital of Anhui University from Jan 2015 to Dec 2020 were divided based on the severity: into SAP group (145 cases) and Non-SAP group (59 cases) with end point survival (177 cases) and death (27 cases). The receiver operating characteristic (ROC) curves were drawn, and the predictive value of IAP, BISAP score and I-B (IAP and BISAP scores) in the severity and the prognosis of AP was studied. Medcalc software was used to compare the areas under ROC curve for different predictors.Results:IAP and BISAP scores increased with the severity of AP ( P<0.001), the area under the ROC curve (AUC) was 0.791, 0.749 and 0.907 respectively,comparison of area under ROC curve showed that I-B combined assessment was superior to IAP value and BISAP score alone in predicting severity ( P<0.05). IAP and BISAP scores were higher in the death group than in the survival group ( P<0.001). The ROC curve results of IAP, BISAP score and I-B combined on the prognosis of AP showed that the AUC was 0.773, 0.841 and 0.950, respectively,comparison of area under ROC curve showed that I-B combined assessment was superior to IAP and BISAP score alone in predicting prognostic value ( P<0.05). Conclusion:Both IAP and BISAP scores can better predict the severity of and the prognosis of AP, and the combination of IAP and BISAP score is more valuable for prediction of prognosis in AP.

Effects of large-volume versus restrictive-volume fluid resuscitation on hemodynamics and prognosis in patients with severe acute pancreatitis / 中国基层医药

Objective:To explore the effect of large-volume versus restrictive fluid resuscitation on hemodynamics and prognosis in patients with severe acute pancreatitis (SAP). Methods:A total of 102 patients with severe acute pancreatitis who received treatment in The Second People's Hospital of Hefei, China between March 2018 and December 2020 were included in this study. They were randomly assigned to undergo large-volume fluid resuscitation (control group, n = 51) or restrictive-volume fluid resuscitation (study group, n = 51). Hemodynamic indexes, intra-abdominal pressure and pulmonary function were compared between the two groups before and after resuscitation. All patients were followed up for 28 days after admission and their prognosis was recorded. Results:At 12 and 24 hours of resuscitation, intrathoracic blood volume index, global end-diastolic volume index, cardiac index, and central venous pressure in the study group were significantly higher than those in the control group (all P < 0.05). At 6 hours of resuscitation, cardiac index and central venous pressure in the study group were (4.87 ± 0.48) and (11.04 ± 2.08), respectively, which were significantly higher than those in the control group [(4.53 ± 0.57), (9.48 ± 1.67), t = 3.25, 4.17, both P < 0.05). Before resuscitation, there was no significant difference in intra-abdominal pressure between the two groups ( P > 0.05). After resuscitation, intra-abdominal pressure in each group was significantly lower compared with that before resuscitation (both P < 0.05). After resuscitation, intra-abdominal pressure in the study group was significantly lower than that in the control group [(12.78 ± 2.35) cmH 2O vs. (15.01 ± 2.42) cmH 2O, t = 4.72, P < 0.05). Before resuscitation, there were no significant differences in PaO 2 and oxygenation index between two groups (both P < 0.05). After resuscitation, PaO 2 and oxygenation index in each group were significantly higher compared with those before resuscitation (both P < 0.05). After resuscitation, PaO 2 and oxygenation index in the study group were significantly higher than those in the control group ( t = 3.02, 5.55, both P < 0.05). The incidence of abdominal compartment syndrome and the incidence of invasive mechanical ventilation in the study group were 27.45% (14/51) and 35.29% (18/51), respectively, which were significantly lower than those in the control group [47.06% (24/51), 56.86% (29/51), χ 2 = 4.19, 4.77, both P < 0.05). There were no significant differences in the incidence of multiple organ dysfunction syndrome, acute renal injury, abdominal drainage rate, mortality between the two groups (all P > 0.05). Conclusion:Compared with large-volume fluid resuscitation, restrictive-volume fluid resuscitation can better improve hemodynamic indexes and pulmonary function, greatly decrease intra-abdominal pressure, and improve prognosis in patients with severe acute pancreatitis.
