Clinical features of recurrent acute pancreatitis complicated with metabolic syndrome and analysis of influencing factors for severe disease / 重庆医学

Objective To investigate the clinical features of patients with recurrent acute pancreatitis(RAP)complicated with metabolic syndrome(MS)and the influencing factors of severe disease.Methods The clini-cal data of 382 RAP patients admitted to the hospital from June 2012 to June 2022 were retrospectively analyzed,and they were divided into the MS group(n=142)and the non-MS group(n=240)according to whether they were combined with MS,and into the severe group(n=29)and the non-severe group(n=353)according to the severity.The general data,serological parameters[triglyceride(TG),total cholesterol(TC),white blood cell count(WBC),neutrophil to lymphocyte ratio(NLR),blood calcium,D-dimer(D-D),lactate dehydrogen-ase(LDH),ALT,AST]and ICU occupancy rate and total length of stay were compared among all groups.Bi-nary logistic regression was used to analyze the independent influencing factors of RAP development into se-vere disease,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for RAP development.Results Hyperlipidemia was the most common cause of RAP in MS group(66.2％),and biliary origin was the most common cause of RAP in non-MS group(44.6％).There was sig-nificant difference among different causes was statistically significant(P＜0.05).There were significant differences in age,gender,proportion of hypertension,diabetes,MS,length of stay,LDH,blood calcium,D-D and NLR levels between the critical and non-critical groups(P＜0.05).The area under the curve(AUC)of blood calcium,D-D,LDH,NLR and combined diagnosis were 0.759,0.777,0.710,0.621,and 0.841,respec-tively.The AUC of single diagnosis had a certain predictive value,but combined diagnosis had a higher predic-tive value.Conclusion The most common cause in the MS group was hyperlipidemia,and the most common cause in the non-MS group was biliary.Blood calcium.D-D,LDH,NLR are reliable indicators to predict the development of RAP into severe disease,and the accuracy of combined diagnosis is higher.

Analysis of the correlation between metabolic syndrome and recurrent acute pancreatitis / 中华消化杂志

Objective:To investigate the correlation between metabolic syndrome (MS)and recurrent acute pancreatitis (RAP).Methods:From June 1, 2012 to June 1, 2023, 463 patients with RAP (recurrent group) who visited the First Affiliated Hospital of Chongqing Medical University were retrospectively collected. The clinical data of 463 patients without RAP (non-recurrent group) during the same period were randomly selected. The patients in the recurrence group were treated at the First Affiliated Hospital of Chongqing Medical University for both initial acute pancreatitis and RAP. The differences in the proportion of patients combined with MS and its components (obesity (body mass index ≥25 kg/m 2), fasting blood triglyceride (TG) ≥1.7 mmol/L, hypertension, hyperglycemia, fasting blood high-density lipoprotein cholesterol (HDL-C) <1.04 mmol/L) between the two groups were analyzed by Chi-square test. Binary logistic regression analysis was used to identify the risk factors of acute pancreatitis recurrence. Results:Among the 463 patients in the recurrent group, there were 221 patients (47.7%) with MS, 276 patients (59.6%) with obesity, 223 patients (48.2%) with hypertension, 185 patients (40.0%) with hyperglycemia, and 365 patients (78.8%) with fasting blood TG ≥1.7 mmol/L. Among the 463 patients in the non-recurrence group, there were 95 patients (20.5%) with MS, 245 patients (52.9%) with obesity, 115 patients (24.8%) with hypertension, 92 patients (19.9%) with hyperglycemia, and 301 patients (65.0%) with fasting blood TG ≥ 1.7 mmol/L. The percentages of MS, obesity, hypertension, hyperglycemia, and fasting blood TG ≥1.7 mmol/L of the recurrent group were all higher than those of the non-recurrent group, and the differences were statistically significant ( χ2=76.27, 4.22, 54.35, 44.55, 21.90; P<0.001, =0.040, <0.001, <0.001, <0.001). There was no statistically significant difference in the percentage of patients with fasting blood HDL-C <1.04 mmol/L between the recurrent group and the non-recurrent group (68.5%, 317/463 vs. 65.4%, 303/463, P>0.05). The results of binary logistic regression analysis showed that combined with MS ( OR=3.538, 95% confidence interval (95% CI) 2.647 to 4.728), hypertension ( OR=2.700, 95% CI 2.025 to 3.602), hyperglycemia ( OR=2.228, 95% CI 1.633 to 3.039), and fasting blood TG ≥1.7 mmol/L ( OR=1.757, 95% CI 1.276 to 2.421) all significantly increased the risk of acute pancreatitis recurrence ( P<0.001, <0.001, <0.001, =0.001). Obesity was not an independent risk factor for RAP ( OR=0.967, 95% CI 0.727 to 1.286, P=0.816). Conclusion:The combination of MS, hypertension, hyperglycemia, and fasting blood TG ≥1.7 mmol/L are independent risk factors for RAP.

Clinical features and risk factors of recurrent acute pancreatitis / 中华胰腺病杂志

Objective:To explore the clinical characteristics and to analyze the risk factors of recurrent acute pancreatitis (RAP).Methods:The clinical data of 3 022 patients with AP from AP database of the Affiliated Hospital of Southwest Medical University between January 2013 and December 2019 were retrospectively analyzed. According to with or without AP relapse and RAP diagnostic criteria, the patients were divided into initial group ( n=2 187) and recurrent group ( n=835). General characteristics, clinical data, and prognostic indicators were compared between the two groups. Multivariate logistic regression analysis was used to explore the risk factors of RAP. Results:The proportion of men, previous biliary disease, hyperlipidemia, diabetes mellitus and previous gallbladder or biliary surgery in recurrent group were significantly higher, while the mean age was significantly lower than that of the initial group. The main causes in the initial group successively were biliary disorders, hyperlipidemia and alcohol, while in the recurrent group were hyperlipidemia, biliary disorders and alcohol. The etiology of hyperlipidemia was significantly higher in the recurrent group than in initial group. The incidence of MAP and regional portal hypertension was significantly higher in the recurrent group, while the incidence of SAP and acute respiratory distress syndrome were significantly lower than those in the initial group, and all the differences were statistically significant(All P value <0.001). The results of the correlation analysis showed that there was no correlation between the severity of RAP and the number of recurrence, and the risk of SAP in RAP did not decrease with the increasing number of recurrence. The results of the multivariate logistic regression analysis showed that previous biliary disorders ( OR=1.303, 95% CI 1.032-1.645, P=0.026), previous history of hyperlipidemia ( OR=2.631, 95% CI 1.580-4.379, P<0.001), and the etiology of hyperlipidemia ( OR=1.773, 95% CI 1.465-2.145, P<0.001) were independent risk factors for RAP. Conclusions:RAP may often occur in middle-aged men and hyperlipidemia is the main cause of RAP, previous history of hyperlipidemia and biliary disease are risk factors for RAP.

Research Progress of Recurrent Acute Pancreatitis / 胃肠病学

Acute pancreatitis is a common acute abdominal disease in clinical practice,some of which can still recur after standardized treatment,known as recurrent acute pancreatitis(RAP).The etiology and mechanism of RAP are complicated,and there is still a lack of standardized evaluation,diagnosis and treatment.So,early identification of the cause and targeted intervention is important.In this review,we summarize the current progress in the research of RAP.

Clinical features of pancreatitis in children: a single center retrospective study / 中国小儿急救医学

Objective:To explore the clinical characteristics of children with pancreatitis, aiming to analyze the clinical differences of acute pancreatitis(AP), recurrent acute pancreatitis(RAP)and chronic pancreatitis(CP)in children.Methods:The clinical characteristics of AP, RAP, CP in children admitted to the Department of Gastroenterology at Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 2015 to December 2020 were analyzed.Results:One hundred and nine cases were included in this study, including 69 cases of AP(63.3%), 22 cases of RAP(20.2%)and 18 cases of CP(16.5%). The proportion of school-age and adolescent children was 48.6% and 29.4%, and there was statistical difference between the composition of children at different ages( P<0.001). Idiopathic was the main cause of AP, RAP and CP.The other causes included biliary, viral infection, structural abnormalities, drug-induced, hypercholesterolemia and heredity.97.2%(106 cases)of the children were accompanied by abdominal pain, mainly in middle and upper abdomen(75 cases, 70.8%)and around umbilical cord(22 cases, 20.8%). The pancreatic enlargement in preschool children was mainly diffuse enlargement(11/12), while the older children with local enlargement and diffuse enlargement accounted for the same proportion, the difference was statistically significant( P=0.037). The height score of CP children was lower than the overall average of the population(0 score), and lower than those of AP and RAP children, with statistically significant difference[-0.65(-1.57, 0.25) vs.0.36(-1.03, 1.05) and -0.09(-0.30, 0.41), H=6.021, P=0.044]. Eight (11.6%) cases with AP progressed to RAP, and six (8.7%) cases with AP progressed to CP. Conclusion:Pancreatitis tends to occur in school-age and adolescent children, and idiopathic is the first cause of all types of pancreatitis.AP, RAP, and CP share common features of pancreatitis in terms of etiology composition and clinical manifestations.Compared with AP and RAP, CP is more likely to affect the growth and development of children.Some children with AP could progress to RAP or CP, so we should pay more attention to the etiological investigation of AP and eliminate the etiological factors in time to avoid the disease progression.

Advances in the pathogenesis and treatment of infantile liver failure syndrome-2 / 国际儿科学杂志

Infantile liver failure syndrome-2(ILFS2)is a rare autosomal recessive disorder caused by neuroblastoma amplified sequence(NBAS)gene mutation, manifested as recurrent acute liver failure(ALF)with fever/infection-related pathogenesis.First-onset ALF is common in infants or early childhood(8 months to 3 years of age). The main characteristic of this disease is that the liver function can be recovered completely in the interval, and the definitive diagnosis is based on the identification of NBAS gene mutation in gene analysis.Until now, the pathogenesis of ILFS2 is not yet fully understood.Patients can be treated by supportive treatment clinically, while liver transplantation is the only treatment option currently available for patients with end-stage ALF.This review will focus on the recent progress in the pathogenesis and treatment of ILFS2.

Evaluation of Recurrent or Idiopathic Pancreatitis / 대한췌담도학회지

Recurrent acute pancreatitis (RAP) is defined as two or more true episodes of acute pancreatitis and about 20% of patients with acute pancreatitis experience at least one episode of recurrence. In about 10% of RAP, no definite etiology is found despite extensive evaluation. This entity is called idiopathic acute pancreatitis (IAP). Toxic-metabolic, idiopathic, genetic, autoimmune, recurrent and severe acute pancreatitis, obstructive (TIGAR-O) classification is commonly used to identify risk factors for RAP. Modalities employed to find causes of RAP and IAP include meticulous history taking, blood tests, diagnostic imaging, genetic testing, bile crystal analysis, endoscopic ultrasonography, and endoscopic retrograde cholangiopancreatography with/without sphincter of Oddi manometry. Each modality is briefly reviewed in this review.

Advances in Research on Etiology of Recurrent Acute Pancreatitis / 胃肠病学

Some patients with acute pancreatitis (AP)can relapse after initial cure. With the development and maturity of diagnosis and treatment technology,especially the rise of endoscopic technology,the detection rate of AP recurrence (such as bile duct stones,Oddi sphincter dysfunction,pancreas divisum,gene mutation,etc. )is increased. Recurrent acute pancreatitis (RAP)is characterized by various causes,and complex mechanisms. Understanding etiology and positive treatment play a pivotal role in reducing the incidence of RAP. This article reviewed the advances in study on etiology of RAP.

Effect evaluation of meticulous nursing management in patients with recurrent acute pancreatitis / 中华胰腺病杂志

Objective To evaluate the application effect of nursing management in the follow-up of patients with recurrent acute pancreatitis (RAP).Methods During January 2016 and January 2017,the clinical data of RAP patients admitted in Changhai Hospital of Navy Medical University was collected.Selfcontrol method was used to establish a prospective cohort study.Meticulous nursing management mode was applied to follow up the patients for 12 months.Patients' compliance,symptom improvement,patients' satisfaction and other markers are evaluated using questionnaires to assess the effect of meticulous nursing management once every 3 months.The data over 12 months were collected.Results Sixty-four RAP patients were finally included.The average follow-up period was 19.7 ±3.4 months.Before admission,the average disease course was(4.21 ± 3.95) years.30 patients (46.9％)had a history of drinking;33 patients (51.6％)had a history of smoking.25 patients (39.1％) had abnormal blood lipid and 40 patients (62.5％) had the dietary habit of high lipid and high protein.The etiology included alcohol (n =10,15.6％),high lipid (n =7,10.9％),biliary diseases (n =1,1.6％),idiopathic causes (n =46,71.9％) and abnormal BMI (n =49,76.6％).After the meticulous nursing management,the frequency of pancreatitis,VAS score of pain and alcohol intake situation was obviously lower than before intervention [(0.50 ±0.85) times/year vs(2.77 ±2.52)times/year;(1.84 ±2.54)vs(6.47 ±2.15);2 cases vs 30 cases].The number of patients who took medicine on time and BMI were obviously decreased[(52 cases vs 13 cases;(23.26 ± 3.85) kg/m2 vs (21.92 ± 4.27)kg/m2)],and the differences were statistically significant (P ＜0.01).Patients' satisfaction with this nursing model was 4.90 ± 0.56.Conclusions The implementation of the new meticulous nursing management model can effectively alleviate patient's symptom condition and improve the compliance behavior and life quality of the patients.

Páncreas divisum y pancreatitis: su importancia en la práctica cotidiana / Pancreas divisum and pancreatitis: its importance in everyday practice

Pancreas divisum (PD) is the most common congenital anatomical variant of the pancreas. Its etiological implication in recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) has been recurrently questioned. Normal anatomy and variants: 80-90% of the population has normal anatomy, with excretion of exocrine pancreatic secretion to the duodenum by the major papilla. Three anatomical variants of PD have been described: classic PD with visible ventral duct, but total absence of fusion; PD with absence of ventral duct; and incomplete PD, with a rudimentary connection between the ventral and dorsal ducts. Clinical implication: This anatomical variant is symptomatic in less than 5% of the carriers, being associated to higher prevalence in patients with RAP However, the relationship between PD and RAP is considered probable, only in cases of association with mutation of the CFTR gene. Obstructive CP can develop in the segment drained by the dorsal duct. Diagnosis: Magnetic resonance cholangiopancreatography (MRCP) is the most sensitive diagnostic method. Other non-invasive diagnostic methods are endosonography and computed tomography (CT), the latter with lower performance. Treatment: The current trend in acute pancreatitis (AP) where PD is assumed as an etiological factor, is endoscopic resolution, with papillotomy with or without a pancreatic stent.

El páncreas divisum (PD) es la variante anatómica congénita más frecuente del páncreas. Su implicancia etiológica en pancreatitis aguda recurrente (PAR) y pancreatitis crónica (PC) ha sido frecuentemente cuestionada. Anatomía normal y variantes: 80-90% de la población presenta anatomía normal, con salida de secreción pancreática exocrina al duodeno por la papila mayor. Se han descrito 3 variantes anatómicas: PD clásico con conducto ventral visible, pero ausencia total de fusión; PD con ausencia de conducto ventral; y PD incompleto, con conexión rudimentaria entre los conductos ventral y dorsal. Implicancia clínica: Esta variante anatómica da síntomas en menos de 5% de los portadores, asociándose a mayor prevalencia en pacientes con PAR. Sin embargo, se considera probable la relación entre PD y PAR, solo en casos de asociación con mutación del gen CFTR. Pancreatitis crónica (PC) obstructiva se puede desarrollar en el segmento drenado por el conducto dorsal. Diagnóstico: La colangiopancreatografía por resonancia magnética (CPRM) es el método diagnóstico más sensible. Otros métodos diagnósticos no invasivos son la endosonografía y tomografía computada (TC), este último de menor rendimiento. Tratamiento: La tendencia actual en PA donde se asume PD como factor etiológico, es la resolución endoscópica, con papilotomía con o sin stent.

Progress in Diagnosis and Treatment of Recurrent Acute Pancreatitis / 胃肠病学

After the initial episode of acute pancreatitis (AP), some patients have a tendency to relapse.With the development of imaging technologies and genetic tests, the diagnostic accuracy of the etiological factors of recurrent acute pancreatitis (RAP) such as dysfunction of sphincter of Oddi, pancreas divisum, and genetic mutations are improved.Clinical studies indicate that etiological treatment by endoscopic approaches may reduce recurrence in some RAP patients.In this article, the progress in etiology, diagnosis and treatment of RAP was reviewed.

Risk factor analysis of recurrent acute pancreatitis / 中华消化杂志

Objective To analyze the clinical features and risk factors of recurrent acute pancreatitis (RAP).Methods From September 2012 to September 2014,the clinical data of 411 patients with primary acute pancreatitis (AP) were collected.From March to June 2016,patients were followed up.The clinical features of patients with RAP were analyzed.Univariate and multivariate regression analysis were performed to analyze the risk factors of RAP.Results Among the 411 patients with AP,those caused by biliary disease,hyperlipidemia,alcohol,other known causes and idiopathic AP were 265 cases (64.5％),61 cases (14.8％),19 cases (4.6％),21 cases (5.1％) and 45 cases (10.9％),respectively.In two weeks of AP onset,the recurrent rate of biliary AP in cholecystectomy group was 7.1％ (5/70),which was lower than that of non-cholecystectomy group (30.2％,42/139),and the difference was statistically significant (xz =14.218,P＜0.01).The results of univariate regression analysis suggested that gender,body mass index (BMI),complicated with diabetes,etiology,history of smoking,history of drinking and pancreatic necrosis were correlated with RAP (all P＜0.05).The results of multivariate regression analysis indicated that complicated with diabetes (odd ratios (OR) =3.417,95 ％ confidence interval (CI) 1.979 to 5.900,P＜0.01),hyperlipidemic pancreatitis (OR=2.247,95％CI 1.077 to 4.688,P=0.023),history of smoking (OR=4.023,95％CI 2.377 to 6.809,P＜0.01),complicated with pancreatic necrosis (OR=3.312,95％ CI 1.675 to 6.546,P＜0.01) were independent risk factors of RAP.Conclusions Hypertriglyceridemia,smoking,complicated with pancreatic necrosis and diabetes are independent risk factors of RAP.Patients with biliary AP should receive cholecystectomy as early as possible,which could reduce RAP.

Prevención de la Diverticulitis Aguda Recurrente on Bacillus clausii

La Enfermedad Diverticular (ED) o Diverticulosis, es una de las enfermedades gastrointestinales más comunes que afectan a la población general en el mundo occidental, un 20 % de los pacientes son sintomáticos y el 75 % de ellos tendrá ED dolorosa: diverticulitis aguda, 25-33 % de estos pacientes pueden tener episodios recurrentes.Cambios en la Microbiota del colon, ocasionando inflamación crónica y proliferación de células epiteliales que se desarrollan en la mucosa del colon en y alrededor de los divertículos. Los prebióticos, restauran el microambiente del colon y de aquí, que se han propuesto para el tratamiento de los pacientes con ED asintomática para evitar la Diverticulitis Aguda. Objetivo del estudio fue investigar la proporción de pacientes que mantuvieron la remisión después de un episodio previo de Diverticulitis Aguda no complicada, cuando recibieron como tratamiento Bacillus clausii: 2 billones cada 8 horas por 1 año. Materiales y métodos: Estudio prospectivo y retrospectivo, con un muestreo no probabilístico de tipo intencional, con grupo control. Grupo A: Los 50 pacientes con el diagnostico de Diverticulitis Aguda no complicada, recibieron como único tratamiento Bacillus clausii 2 billones cada 8 horas, permanente por 1 año. Controles clínicos cada 3 meses. Grupo B (control): 50 pacientes conel diagnostico de Diverticulitis Aguda no complicada no tratados.Resultados:Se introdujo la información necesaria para realizar los análisis de varianza en R, encontrándose diferencia significativa entre las medias de los grupos considerados en el estudio, al obtenerse un F(1,48)=5.259, p <0.05.Conclusión: El Bacillus clausii por su características biológicas previene las complicaciones inflamatorias de la Enfermedad Diverticular como es la Diverticulitis Aguda Recurrente.

Diverticular Disease (DD), or Diverticulitis, is one of the most common gastrointestinal diseases affecting the general population in the western world; approximately 20% of patients are symptomatic and 75% suffer from painful DD: acute diverticulitis, 25-33% of those patients may suffer from recurrent episodes. Changes in colon microbiota cause chronic inflammation and epithelial cell proliferation developed in colon mucosa and around the diverticula. Prebiotics restore colon’s microenvironment, from where the treatment of patients with asymptomatic DD is proposed, in order to avoid the Acute Diverticulitis. The study aimed to investigate the proportion of patients who maintained the referral after a previous episode of uncomplicated Acute Diverticulitis, when treated with Bacillus clausii: two billions every eight hour during one year. Materials and Methods: Prospective and retrospective study, with non-probabilistic, intentional-type sampling and control arm. Arm A: Fifty patients diagnosed with uncomplicated Acute Diverticulitis, were administered with a single treatment of Bacillus clausii, two billions, every eight hours during one year. Clinical controls every three months. Arm B (control): 50 untreated patients diagnosed with uncomplicated Acute Diverticulitis. Outcomes: The necessary information to carry out the R variance analysis was introduced; a significant difference was found between the study’s arm averages; a F(1,48)=5.259, p<0.05 was found. Conclusion: because of its biological characteristics, Bacillus clausii prevents Diverticular Disease’s inflammatory complications such as the Recurrent Acute Diverticulitis.

A Case of Combined Congenital Hepatic Fibrosis and Biliary Hamartoma Presented with Recurrent Acute Cholangitis / 대한췌담도학회지

Biliary hamartoma and congenital hepatic fibrosis belong to fibrocystic disorders originating from ductal plate malformation. A 66-year-old man who had incidentally been diagnosed with biliary hamartoma two years ago presented to us with recurrent acute cholangitis. In the first episode, he had presented with septic shock and was treated with endoscopic retrograde cholangiopancreatography (ERCP) and cholecystectomy under the diagnosis of acute cholecystitis and cholangitis. However, during a two-month follow-up period, the patient experienced four episodes of acute cholangitis. Because he showed normal ERCP, and biliary hamartoma is usually asymptomatic, a liver biopsy was performed. Pathology revealed combined features of biliary hamartoma and congenital hepatic fibrosis, characterized as periportal fibrosis and intrahepatic ductular dysplasia. During follow-up for the last six months, he had experienced two episodes of acute cholangitis and was treated with antibiotics. A follow-up abdominal CT scan revealed aggravated hepatosplenomegaly compared to that of two years ago. We report a case of combined congenital hepatic fibrosis and biliary hamartoma and a literature review.

Pielonefritis aguda recurrente en mujeres / Recurrent acute pyelonephritis in women

Se realizó un estudio descriptivo transversal para describir el comportamiento de la pielonefritis aguda recurrente en mujeres de 18 y más años de edad, que ingresaron en el Hospital Mártires del 9 de Abril de Sagua la Grande, de enero de 2004 a junio de 2007. El universo estuvo constituido por las 593 pacientes ingresadas con ese diagnóstico. Se realizó un muestreo no probabilístico por criterios y la muestra quedó constituida por 67 pacientes. Las edades fluctuaron entre 18 y 85 años. Las manifestaciones clínicas más comunes fueron: dolor lumbar, fiebre y síntomas urinarios bajos. En el examen físico se halló dolor a la palpación profunda de las fosas lumbares, prácticamente, en todos los casos. El diagnóstico de certeza se realizó por el urocultivo, en 104 ocasiones. Los gérmenes que con mayor frecuencia infectaron las vías urinarias altas fueron bacilos gramnegativos y E. Coli fue el más común. La mayor sensibilidad fue a la amikacina y la mayor resistencia, a ampicillina, ciprofloxacilo y ácido nalidíxico. Muchas de las pacientes con mayor cantidad de ingresos tenían anomalías estructurales de las vías urinarias. La enfermedad subyacente más frecuentemente asociada fue la diabetes mellitus

A descriptive cross-sectional study was conducted to describe the behavior of recurrent acute pyelonephritis in women of 18 years of age and older who were admitted to Mártires del 9 de Abril Hospital in Sagua La Grande, from January 2004 to June 2007. The universe was composed of the 593 patients who were admitted with this diagnosis. A non-probabilistic sampling criterion was performed and then, the sample was composed of 67 patients. The ages ranged from 18 to 85 years. The most common clinical manifestations were low back pain, fever and low urinary symptoms. On physical examination, pain on deep palpation of the lumbar fosses was found, practically, in all cases. The diagnosis of certainty was made by urine culture in 104 occasions. The most common germs that infected the upper urinary tracts were gram-negative bacilli, and E. coli was the most common. The greatest sensitivity was seen for Amikacin and the resistance was greater to Ampicillin, Ciprofloxacin and Nalidixic Acid. Many of the patients with the majority of admissions presented structural anomalies of the urinary tract. The most frequently associated underlying disease was diabetes mellitus

Estudio y manejo de la pancreatitisaguda recurrente / Study and management of recurrent acute pancreatitis

Acute pancreatitis is caused by biliary lithiasis or alcohol consumption in 70-90 percent of the cases; however, depending on the depth of the etiological study, 5 to 30 percent of the cases do not have an apparent cause. An undetected condition that is potentially amendable may lead to recurrent episodes of acute pancreatitis. Among the proposed strategies for the management of idiopathic acute pancreatitis patients (first or recurrent episode) it is suggested –in addition to repeated transabdominal ultrasound and the clinical laboratory tests– the performance of other studies such as: microscopic examination of bilis to demonstrate biliary sludge or microlithiasis; endoscopic ultrasound, that in addition to its high sensitivity for detecting bilairy lithiasis, it also helps to detect solid, cystic or periampullary pancreatic lesions, early changes of chronic pancreatitis and other biliopancreatic anatomical conditions; same as nuclear magnetic resonance (NMR). Diagnostic endoscopic retrograde cholangiopancreatography (ERCP) has left its place to the mentioned imaging studies, but keeping its diagnostic role in the manometric study of the sphincter of Oddi when suspecting a disorder. Presentation of patients with chronic pancreatitis as well as recurrent pancreatitis episodes expands the scope of search. Prophylactic cholecystectomy without futher investigation is a plausible alternative due to hte high frequency of lithiasic disease, mainly considering the low availability and high cost of the proposed studies. In cholecystectomized patients, prophylactic ERCP without futher investigation showing a potentially treatable disease using this or other methods is discouraged, due to the high frequency of acute pancreatitis post-ERCP, if the underlying disease is an Oddi sphincter dysfunction. In this case it is suggested that the procedure must be performed in a health center with vast experience in this technique.

La pancreatitis aguda es causada en un 70-90 por ciento por litiasis biliar o consumo excesivo de alcohol, pero, dependiendo de la profundidad del estudio etiológico realizado, 5 a 30 por ciento de los casos no tienen causa aparente. La falta de detección de una condición potencialmente corregible puede llevar a episodios recurrentes de pancreatitis aguda. Entre las diferentes estrategias propuestas para el manejo de pacientes con pancreatitis aguda idiopática (sea primer episodio o episodio recurrente), se sugiere, además de repetir la ecografía transabdominal y el laboratorio bioquímico habitual, realizar estudios como: el análisis microscópico de bilis para demostrar barro biliar o microlitiasis; ultrasonografía endoscópica, que además de una alta sensibilidad para detectar litiasis biliar permite también la detección de lesiones sólidas o quísticas pancreáticas o periampulares, cambios precoces de pancreatitis crónica y otras alteraciones anatómicas biliopancreáticas; al igual que la resonancia nuclear magnética (RNM). La colangiopancreatografía retrógrada endoscópica (CPRE) diagnóstica ha cedido su lugar a los estudios de imágenes antes mencionados, manteniendo su papel diagnóstico en el estudio manométrico del esfínter de Oddi ante la sospecha de disfunción. La presentación de pacientes con pancreatitis crónica como crisis de pancreatitis recurrente amplía el espectro de búsqueda. La colecistectomía profiláctica sin mayor estudio es una alternativa planteable dada la alta frecuencia de patología litiásica, sobre todo considerando la baja disponibilidad y alto costo de los estudios propuestos. En pacientes colecistectomizados, la CPRE profiláctica sin nuevos estudios que demuestren una patología eventualmente tratable por este u otros métodos, se desaconseja por la alta frecuencia de pancreatitis aguda post CPRE si la patología subyacente es una disfunción del esfínter de Oddi. Se sugiere en este caso su realización en centros con amplia experiencia...

Ecoendoscopia en niños con pancreatitis aguda recurrente / Echoendoscopic in children with recurrent acute pancreatitis

Introducción: el abordaje diagnóstico de pacientes con episodios de pancreatitis aguda recurrente supone un reto cuando el laboratorio y los estudios por imágenes son negativos. El ultrasonido endoscópico constituye una herramienta diagnóstica para la detección de patologías biliopancreáticas. Caso 1: escolar masculino de 11 años de edad, antecedentes de deportes de contacto, ingresa con dolor abdominal y vómitos biliosos. Amilasa en 1.987 U/L, lipasa 558 U/L, serologías virales negativas, perfil metabólico normal, ecosonograma abdominal sin alteraciones, se realiza diagnóstica de pancreatitis aguda de probable origen post traumático. Reingresa 4 meses después con sintomatología similar, y nuevamente los estudios son negativos. Ecoendoscopia a los 3 meses del último episodio: microlitiasis vesicular y páncreas sin alteracion. Posterior al procedimiento presenta tercer episodio de pancreatitis. El paciente es referido a cirugía. Caso 2: escolar de 7 años, inicia su enfermedad con pancreatitis aguda y peritonitis, con evolución satisfactoria. Al año reaparece episodio de pancreatitis, cifras de amilasa de 2.786 U/L y lipasas 755 U/L, que se repite en dos oportunidades en 4 años. En ninguna hospitalización se logra detectar alteraciones del perfil lipídico e inmunológico, electrolitos en sudor negativo y ecografía y tomografía abdominal no reportaron información complementaria. Se realiza ecoendoscopia que revela cambios en parénquima pancreático sugestivo de proceso inflamatorio agudo. Se indica colangioresonacia que reporta alteraciones del calibre del hepático común, colédoco y Wirsung. Se programa para esfinterotomía. Conclusiones: identificar la causa de la pancreatitis aguda recurrente requiere de la combinación de laboratorio y estudios por imágenes. En estos pacientes la ecoendoscopia contribuyó con el diagnóstico etiológico en uno de ellos y en el otro, alteraciones del parénquima pero no en el sistema ductal.

Introduction: the diagnostic approach of patients with recurrent episodes of acute pancreatitis is a challenge when the laboratory and imaging studies are negative. Endoscopic ultrasound is a diagnostic tool for detection of biliopancreatic diseases. Case 1: male school 11 years of age, history of contact sports, was admitted with abdominal pain and bilious vomiting. Amylase 1,987 U/L, lipase 558 U/L, negative viral serology, normal metabolic profile, unaltered abdominal ultrasound is performed diagnostic of acute pancreatitis of probable traumatic origin. Readmitted 4 months later with similar symptoms, and again these studies are negative. Endoscopic ultrasound at 3 months of the last episode: microlithiasis gallbladder and pancreas preserved. After the procedure has third episode of pancreatitis. The patient is referred to surgery. Case 2: School of 7 years, the disease starts with acute pancreatitis and peritonitis, with satisfactory outcome. Reappears year episode of pancreatitis, serum amylase up to 2,786 U/L and lipase 755 U/L, which is repeated twice in 4 years. In no hospitalization was unable to detect alterations in the lipid profile and immune negative sweat electrolytes and abdominal ultrasound and CT did not report information. EUS is performed that reveals changes in pancreatic parenchyma suggestive of acute inflammatory process. From magnetic resonance indicated that reports of liver disorders caliber common bile duct and Wirsung. He was scheduled for intubation. Conclusions: Identifying the cause of recurrent acute pancreatitis requires a combination of laboratory and imaging studies. EUS in these patients contributed to the etiologic diagnosis in one and in the other parenchymal but not in the ductal system.
