ABSTRACT
Pancreatoscopy is an advanced endoscopic technique that allows direct observation of the main pancreatic duct, facilitating both diagnosis and treatment of various pancreatic conditions. It enables biopsies and assessment of lesion malignancy. This procedure is performed under deep sedation or anesthesia, with non-steroidal anti- inflammatory drugs recommended for prophylaxis. It is primarily used in diagnosing pancreatic duct strictures and intraductal papillary mucinous neoplasms. Within treatment, its utility is highlighted in intraductal lithotripsy, especially in cases of chronic pancreatitis. The most common adverse effect is acute post-procedural pancreatitis, though estimated in less than 5% of cases. Proper technique, saline administration control, and placement of stents at the end of procedure help minimize complications. Despite being reserved as second-line therapy for pancreatic lithiasis, it offers several advantages over traditional techniques, and it is anticipated that with some advancements in the future, it will become a first-line therapeutic option.
La pancreatoscopia es una técnica endoscópica que permite la observación directa del conducto pancreático prin- cipal, facilitando tanto el diagnóstico como el tratamiento de diversas afecciones pancreáticas. Permite realizar biopsias y evaluar la malignidad de las lesiones. Este procedimiento se realiza bajo sedación profunda o anestesia, y se recomienda la administración de antiinflamatorios no esteroidales en forma de profilaxis. Se utiliza princi- palmente en el diagnóstico de estenosis del conducto pancreático y neoplasias mucinosas papilares intraductales. En el tratamiento, se destaca su utilidad en la litotricia intraductal, especialmente en casos de pancreatitis crónica. El efecto adverso más común es la pancreatitis aguda posprocedimental, aunque se estima en menos del 5% de los casos. Una adecuada técnica, control del suero y la colocación de prótesis al final del procedimiento ayudan a minimizar las complicaciones. A pesar de reservarse como segunda línea en el tratamiento de litiasis pancreáti- cas, presenta diversas ventajas sobre técnicas tradicionales, y se espera que con algunos avances en un futuro se convierta en una opción de primera línea terapéutica.

La hidatidosis pancreática representa el 0,2-0,6 % de los casos, siendo la población pediátrica la de mayor riesgo. Las lesiones suelen localizarse en cabeza del páncreas (50-58 %); la localización en cuerpo y cola del páncreas se encuentra en el 24-34 % y el 19 %, respectivamente. Dada la posibilidad de complicaciones, suele realizarse tratamiento quirúrgico. Se sugiriere indicar albendazol antes y después del acto quirúrgico por los riesgos de ruptura y diseminación de los protoescólices. Se presenta el caso de una niña de 5 años de edad con dolor abdominal progresivo y lesión quística en páncreas compatible con hidatidosis en la ultrasonografía. En la tomografía computada se observa compresión de la vía biliar. La hemoaglutinación indirecta fue negativa. Presentó elevación de la bilirrubina total, con franco predominio de bilirrubina directa, y aumento de enzimas hepáticas. Se realizó laparotomía exploradora, colecistectomía y destechamiento del quiste. Evolucionó favorablemente, continuó con albendazol durante 3 meses luego de la cirugía.
Pancreatic echinococcosis accounts for 0.20.6% of cases, with the pediatric population being at a higher risk. Most commonly, pancreatic lesions occur in the head of the pancreas (5058%); and in the body and tail in 2434% and 19% of cases, respectively. Given the potential complications, surgery is usually performed. Albendazole is recommended before and after the surgery due to the risks for rupture and dissemination of protoscolices. Here we describe the case of a 5-year-old girl with progressive abdominal pain and cystic lesion in the pancreas compatible with echinococcosis in the ultrasound. The computed tomography showed bile duct compression. Indirect hemagglutination was negative. She had elevated total bilirubin, with a clear predominance of direct bilirubin, and high liver enzymes. Exploratory laparotomy, cholecystectomy, and unroofing of the cyst were performed. The patient had a favorable course and continued with albendazole for 3 months after the surgery.

Objective: To analyze the therapeutic effect and safety of pancreatic extracorporeal shock wave lithotripsy(P-ESWL) for patients with chronic pancreatitis complicated by stones of the pancreatic duct and to investigate the influencing factors. Methods: A retrospective analysis was performed on clinical data from 81 patients with chronic pancreatitis complicated by pancreatic duct calculus treated with P-ESWL in the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Xi 'an Jiaotong University from July 2019 to May 2022. There were 55 males(67.9%) and 26 females(32.1%). The age was (47±15)years (range: 17 to 77 years). The maximum diameter(M(IQR)) of the stone was 11.64(7.60) mm, and the CT value of the stone was 869 (571) HU. There were 32 patients (39.5%) with a single pancreatic duct stone and 49 patients(60.5%) with multiple pancreatic duct stones. The effectiveness, remission rate of abdominal pain, and complications of P-ESWL were evaluated. Student's t test, Mann Whitney U test, χ2 test, or Fisher's exact test was used to compare the characteristics between the effective and ineffective groups of lithotripsy. The factors influencing the effect of lithotripsy were analyzed by univariate and multivariate logistic regression analysis. Results: Eighty-one patients with chronic pancreatitis were treated with P-ESWL 144 times, with an average of 1.78 (95%CI:1.60 to 1.96) times per person. Among them, 38 patients(46.9%) were treated with endoscopy. There were 64 cases(79.0%) with effective removal of pancreatic duct calculi and 17 cases(21.0%) with ineffective removal. Of the 61 patients with chronic pancreatitis accompanied by abdominal pain, 52 cases(85.2%) had pain relief after lithotripsy. After lithotripsy treatment, 45 patients(55.6%) developed skin ecchymosis, 23 patients(28.4%) had sinus bradycardia, 3 patients(3.7%) had acute pancreatitis, 1 patient(1.2%) had a stone lesion, and 1 patient(1.2%) had a hepatic hematoma. Univariate and multivariate logistic regression analysis showed that the factors affecting the efficacy of lithotripsy included the age of patient(OR=0.92, 95%CI: 0.86 to 0.97), the maximum diameter of the stone(OR=1.12,95%CI:1.02 to 1.24) and the CT value of the stone(OR=1.44, 95%CI: 1.17 to 1.86). Conclusions: P-ESWL is effective in the treatment of patients with chronic pancreatitis complicated by calculi of the main pancreatic duct.Factors affecting the efficacy of lithotripsy include patient's age, maximum stone diameter, and CT value of calculi.

BACKGROUND: Nonalcoholic fatty pancreatitis (NAFP) is one of the metabolic syndrome manifestations that need further studies to determine its molecular determinants and find effective medications. We aimed to investigate the potential effect of benzyl propylene glycoside on NAFP management via targeting the pancreatic cGAS-STING pathway-related genes (DDX58, NFκB1 & CHUK) and their upstream regulator miRNA (miR-1976) that were retrieved from bioinformatics analysis. METHODS: The rats were fed either normal chow or a high-fat high-sucrose diet (HFHS), as a nutritional model for NAFP. After 8 weeks, the HFHS-fed rats were subdivided randomly into 4 groups; untreated HFHS group (NAFP model group) and three treated groups which received 3 doses of benzyl propylene glycoside (10, 20, and 30 mg/kg) daily for 4 weeks, parallel with HFHS feeding. RESULTS: The molecular analysis revealed that benzyl propylene glycoside could modulate the expression of the pancreatic cGAS-STING pathway-related through the downregulation of the expression of DDX58, NFκB1, and CHUK mRNAs and upregulation of miR-1976 expression. Moreover, the applied treatment reversed insulin resistance, inflammation, and fibrosis observed in the untreated NAFP group, as evidenced by improved lipid panel, decreased body weight and the serum level of lipase and amylase, reduced protein levels of NFκB1 and caspase-3 with a significant reduction in area % of collagen fibers in the pancreatic sections of treated animals. CONCLUSION: benzyl propylene glycoside showed a potential ability to attenuate NAFP development, inhibit pancreatic inflammation and fibrosis and reduce the pathological and metabolic disturbances monitored in the applied NAFP animal model. The detected effect was correlated with modulation of the expression of pancreatic (DDX58, NFκB1, and CHUK mRNAs and miR-1976) panel.

Objective: Reinforce that, despite being a rare condition, the annular pancreas must be considered a differential diagnosis for intestinal obstructions in the newborn period. Case description: This case report refers to a 13-days newborn admitted to the emergency room presenting with postprandial vomiting and progressive weight loss since maternity discharge. The patient did not respond to initial interventions that included IV antibiotics and nasogastric tube insertion. A contrast study of the upper digestive tract (esophagus, stomach, and duodenum) found a luminal narrowing on the second duodenal portion. The patient was submitted to an exploratory laparotomy which found a pancreatic-tissue ring involving the second part of the duodenum. Despite rare, we reinforce that the annular pancreas must be considered a differential diagnosis for intestinal obstructions in the newborn period. Comments: Annular pancreas is a rare congenital defect in which a ring of pancreatic tissue encircles the duodenum, causing different degrees of intestinal obstruction. (AU)

Autoimmune pancreatitis is a characteristic manifestation of the spectrum of the disease related to IgG4, a rare autoimmune disorder that presents clinically with obstructive jaundice due to the infiltration of plasma cells and fibrosis in the pancreas. There may be other symptoms in case of involvement of other organs, and in very rare cases there is hematological involvement. We present the case of an adult man with signs of cholestasis secondary to type I autoimmune pancreatitis, with involvement of other organs and associated with thrombocytopenia that improved with systemic corticosteroid-based immunosuppressive treatment, after which the patient showed favorable clinical and analytical evolution over time.

El ultrasonido endoscópico ha cambiado la evaluación de las enfermedades pancreáticas y ha logrado un diagnóstico histopatológico (cuando se asocia con la punción); sin embargo, este procedimiento requiere de entrenamiento, no está libre de complicaciones y alrededor de 25% de los pacientes puede tener falsos negativos. Por esto se ha implementado el uso de la elastografía cuantitativa con el strain ratio, el cual permite diferenciar las masas benignas de las malignas. Existe evidencia creciente, pero aún no conclusiva, dada la heterogeneidad de los resultados (sin consenso para su realización), por lo que es necesario desarrollar otros métodos, que permitan una mayor certeza diagnóstica, como el índice de fibrosis hepática (IFH) medido por ultrasonografía endoscópica, el cual tienen como base la inteligencia artificial, validado para el diagnóstico y el seguimiento de la fibrosis hepática. Nuestro grupo considera que se podría usar de la misma forma para valorar el parénquima pancreático. Objetivo: evaluar si el IFH puede diferenciar tres tipos diferentes de tejidos pancreáticos: páncreas normal, páncreas graso y cáncer de páncreas. Metodología: estudio prospectivo de corte transversal en un solo centro. Se incluyeron 66 pacientes mayores de 18 años, con indicación de ultrasonografía endoscópica. El grupo 1 fue de pacientes con indicación diferente a la enfermedad biliopancreática (55 pacientes). En este grupo se aplicó la escala de clasificación de páncreas graso por ultrasonografía endoscópica (USE), utilizando como referencia la ecogenicidad del bazo (previamente validada); este grupo se subdividió en uno con parénquima pancreático normal y en otro con páncreas graso. En el grupo 2 (11 pacientes) se incluyeron los pacientes llevados para el estudio de lesión sólida pancreática, con diagnóstico citológico positivo para carcinoma de páncreas. Como herramienta de recolección de datos se utilizó un formulario virtual de Google Drive, disponible con dirección acortada: shorturl.at/pIMWX, diligenciado antes y después del procedimiento por fellows de Gastroenterología, previamente entrenados para este fin. El IFH se tomó en el páncreas en tiempo real mediante un software suministrado por el fabricante (Hitachi-Noblus), en un período comprendido entre enero de 2019 y enero 2020. A todos los pacientes se les realizó una ecoendoscopia biliopancreática completa, con un ecoendoscopio Pentax lineal y procesador Hitachi-Noblus; luego se efectuó una elastografía cualitativa y una cuantitativa, la cual incluyó la medición del IFH. Resultados: en total se incluyeron 66 pacientes: 11 pacientes con diagnóstico confirmado por citología de cáncer de páncreas y 55 pacientes que se enviaron para ecoendoscopia por evaluación de otras patologías diferentes a la biliopancreática. El rango de edad fue de 23-89, media de 56,75 años. El antecedente más frecuente fue la esteatosis o esteatohepatitis (n = 14) (25,45%). La indicación para la realización del procedimiento más frecuente fue la lesión subepitelial (n = 29) (52,73 %). Los porcentajes de pacientes según los grados de ecogenicidad del páncreas fueron de grado I (n = 29) (52,73 %); grado II (n = 5) (9,09 %); grado III (n = 18) (32,73 %); grado IV (n = 3) (5,45 %). Se tomaron los grados I y II como páncreas normal, y los grado III y IV como páncreas graso. Estos se dividieron en n = 34 pacientes (61,82 %) para páncreas normal y n = 21 (38 %) para páncreas graso; es decir, que de acuerdo con la escala utilizada hay una prevalencia para páncreas graso de 38,18 %. Se realizó el IFH en los tres subgrupos diferentes: los considerados como ecoendoscópicamente normales, los clasificados como páncreas graso y los pacientes con diagnóstico de cáncer de páncreas confirmado por citología, tomado en el páncreas. El IFH para los tres diferentes grupos fueron, respectivamente, normal: IFH 2,60, rango 0,97-3,47 (IC 95 % 2,17-3,02); páncreas graso: IFH 3,87, rango 2-5,5 (IC 95 % 3,44-4,29); cáncer de páncreas: IFH 6,35, rango 5,8-7,8 (IC 95 % 5,92-6,77). Conclusiones: este es el primer estudio piloto que usa el IFH aplicado al parénquima pancreático, y se sugiere su utilidad para diferenciar, de manera no invasiva, el páncreas normal, el graso y el carcinoma de páncreas. Este hallazgo se debe confirmar en poblaciones más amplias y heterogéneas, con el fin de ser validado.
Abstract Endoscopic ultrasound has changed the evaluation of pancreatic diseases and has achieved a histopathological diagnosis (when associated with a puncture); however, this procedure requires training, is not free of complications, and around 25 % of patients may have false negatives. Therefore, quantitative elastography with the strain ratio has been implemented to differentiate benign masses from malignant ones. There is growing but not yet conclusive evidence, given the heterogeneity of the results (without consensus on its performance). It is necessary to develop other methods that allow for greater diagnostic certainty, such as the liver fibrosis index (LFI) measured by endoscopic ultrasonography. This method is based on artificial intelligence and validated for diagnosing and monitoring liver fibrosis. Our group considers that it could also be used to assess the pancreatic parenchyma. Aim: To evaluate whether the LFI can differentiate three types of pancreatic tissues: normal pancreas, fatty pancreas, and pancreatic cancer. Materials and methods: Prospective cross-sectional single-center study. We included sixty-six patients over 18 years of age with an indication for endoscopic ultrasonography. Group 1 consisted of patients with an indication other than the biliopancreatic disease (55 patients). The endoscopic ultrasonography (EUS) fatty pancreas classification scale was applied to this group, taking the echogenicity of the spleen (previously validated) as a reference; this group was subdivided into normal pancreatic parenchyma and fatty pancreas. Group 2 (11 patients) included those examined for solid pancreatic lesions with a positive cytological diagnosis of pancreatic carcinoma. We used a Google Form as a data collection tool, available with a shortened address (shorturl.at/pIMWX). It was filled out before and after the procedure by Gastroenterology fellows, previously trained for this purpose. The LFI was measured in the pancreas in real-time using software supplied by the manufacturer (Hitachi Noblus) between January 2019 and January 2020. All patients underwent a complete biliopancreatic echoendoscopy, with a linear Pentax echoendoscope and Hitachi Noblus processor. Then, qualitative and quantitative elastography was performed, including LFI measurement. Results: We included a total of 66 patients: 11 with a diagnosis of pancreatic cancer confirmed by cytology and 55 sent for ultrasound endoscopy due to pathologies other than the biliopancreatic disease. The age range was 23-89, with a mean of 56.75 years. The most frequent history was steatosis or steatohepatitis (n = 14) (25.45 %). The most frequent indication for performing the procedure was subepithelial lesion (n = 29) (52.73 %). The percentages of patients according to pancreatic echogenicity were Grade I (n = 29) (52.73 %); Grade II (n = 5) (9.09 %); Grade III (n = 18) (32.73 %); Grade IV (n = 3) (5.45 %). Grades I and II were taken as a normal pancreas and Grades III and IV as a fatty pancreas, divided into n = 34 patients (61.82 %) for a normal pancreas and n = 21 (38 %) for a fatty pancreas. According to the scale used, there is a fatty pancreas prevalence of 38.18 %. The LFI was measured in three subgroups: those considered endoscopically normal, those classified as fatty pancreas, and patients diagnosed with pancreatic cancer confirmed by cytology taken from the pancreas. The LFI for these groups were, respectively, normal pancreas: LFI 2.60, range 0.97-3.47 (95 % CI 2.17-3.02); fatty pancreas: LFI 3.87, range 2-5.5 (95 % CI 3.44-4.29); pancreatic cancer: LFI 6.35, range 5.8-7.8 (95 % CI 5.92-6.77). Conclusions: This is the first pilot study that applies the LFI to the pancreatic parenchyma. It is useful in differentiating a normal pancreas, a fatty pancreas, and pancreatic carcinoma non-invasively. This finding must be validated in larger and more heterogeneous populations.

Pancreatic panniculitis (PP) is a necrotizing inflammation of subcutaneous fat that is a rare complication of pancreatic disease appearing in 2% to 3% of all patients. It is more common in the elderly and often affects the extremities. It presents as skin inflammation with pain and erythema nodules. We report a case of acute pancreatitis associated with PP in an old female. She was admitted for vomiting and abdominal pain for 3 days and presented with a 2-week history of erythematous subcutaneous nodules on her legs. Laboratory and ultrasonic findings revealed acute pancreatitis. High frequency ultrasound showed hypoechoic foci in subcutaneous soft tissue layer and adipose layer. Histopathological examination confirmed the diagnosis of PP. Nodules disappeared with the resolution of acute pancreatic inflammation. PP may be the first manifestation of pancreatic disease. Imaging features of this pathology are seldom described and ultrasonic diagnosis experience is worth to be accumulated.

IgG4-related disease (IgG4-RD) is an immune-mediated condition associated with chronic fibroinflammatory lesions that can affect nearly any organ. IgG4-related hepatobiliary and pancreatic diseases are IgG4-RD involving the hepatobiliary and pancreatic system, which is characterized with elevated serum IgG4 concentrations, large numbers of IgG4 positive lymphoplasma cells infiltration in affected organs, storiform fibrosis, and imaging changes of organ morphology. Due to the lack of reliable biomarkers, histopathology is still an important basis for diagnosis. The pathogenesis of IgG4-related hepatobiliary and pancreatic diseases has not been clarified. This review focuses on the recent advances in intestinal microecology-immunology, host genetics-immunity and recurrence monitoring of IgG4-related hepatobiliary and pancreatic diseases.

Despite a growing number of investigative studies on pancreatic fat deposition, there remains no clear indication regarding the clinical relevance of fat infiltration in the pancreas, also called fatty pancreas (FP). An individual's body weight is correlated with their pancreatic weight. Moreover, lipid infiltration causes disorders that compromise not only morphology but also metabolic functions. Fat infiltration leads to insulin resistance, type II diabetes mellitus, and pancreatic cancer; however, knowledge about pancreatic fat content and aspects related to the clinical profile remains unclear in the literature. The present review describes the current knowledge of FP, including its pathophysiology and clinical implications, as well as lifestyle changes in FP.

ABSTRACT Fat infiltration in the pancreas is called pancreatic steatosis and it has several synonyms such as pancreatic lipomatosis, non-alcoholic fatty pancreatic disease, lipomatous pseudohypertrophy, fatty replacement, fatty pancreas and fatty infiltration. Pancreatic steatosis describes a disease ranging from infiltration of fat in the pancreas to pancreatic inflammation, and development of pancreatic fibrosis. There are multiple aetiologies of this condition, such as metabolic syndrome, alcohol intake, viral infections, toxins, congenital syndromes, etc. Pancreatic steatosis is usually diagnosed by trans-abdominal ultrasound, computed tomography scan and magnetic resonance imaging. Fatty infiltration in pancreas may lead to pancreatitis, diabetes mellitus and may be a predisposing cause of pancreatic cancer. Now a day, pancreatic steatosis is a common incidental finding during abdominal ultrasonography for other reasons and is a new challenge in Gastroenterology. But there is no guideline for pancreatic steatosis till now. In this review article, we are trying to give an overall idea (aetiologies, diagnosis, management, clinical significances) on pancreatic steatosis.
RESUMO A infiltração de gordura no pâncreas é chamada de esteatose pancreática ou lipomatose pancreática e tem vários sinônimos tais como: doença pancreática gordurosa não alcoólica, pseudo hipertrofia lipomatosa, reposição gordurosa, pâncreas gorduroso e infiltração gordurosa. A esteatose pancreática descreve uma doença que vai desde a infiltração de gordura no pâncreas até a inflamação pancreática com o desenvolvimento de fibrose pancreática. Existem múltiplas causas dessa condição, como síndrome metabólica, ingestão de álcool, infecções virais, toxinas, síndromes congênitas, etc. A esteatose pancreática é geralmente diagnosticada por ultrassom trans-abdominal, tomografia computadorizada ou ressonância magnética. A infiltração gordurosa no pâncreas pode levar à pancreatite e pode ser uma causa predisponente ao câncer de pâncreas. Hoje em dia, a fibrose pancreática é um achado incidental comum durante a ultrassonografia abdominal realizada por outras razões e é um novo desafio na Gastroenterologia. Mas não há diretriz para esteatose pancreática até agora. Neste artigo de revisão, objetivamos dar uma ideia geral sobre esteatose pancreática.

RESUMEN Introducción: El drenaje guiado por ecoendoscopía es considerado como la mejor opción para el drenaje de las colecciones liquidas peripancreáticas. No hay reportes en nuestro medio de la experiencia en esta terapia endoscópica. Objetivos: detallar las características, eficacia y seguridad de los drenajes ecoendoscópicos de las colecciones liquidas peripancreáticas en el Hospital Nacional Edgardo Rebagliati Martins. Material y métodos: se realizó un estudio transversal retrospectivo de todos los pacientes con colecciones liquidas peripancreáticas sintomáticas sometidos a drenaje ecoguiado. Se analizaron variables demográficas, características ecoendoscópicas asociadas al procedimiento terapéutico y dispositivos empleados. La eficacia se evaluó con la tasa de éxito técnico y de éxito clínico. La seguridad se evaluó en base a las principales complicaciones inmediatas y posteriores. Se empleó estadística descriptiva básica. Resultados: Se realizaron 17 drenajes ecoguiadas de colecciones peripancreáticas (10 pseudoquistes y 7 necrosis pancreáticas encapsuladas o WON) en 17 pacientes: 9 mujeres (52,9%) y 8 hombres (47,1%). El rango de edad de los pacientes fue de 26-72 años, con una mediana de 59 años. El tamaño promedio de las colecciones liquidas fue 14,8 cm con un rango de 8-24 cm. El acceso transgástrico se empleó en 16 casos (94,1%) y el acceso transduodenal en 1 caso (5,9%). Se empleó prótesis plástica (6 casos), prótesis metálica autoexpandibles (SEMS) biliar (4 casos) y prótesis de aposición luminal (LAMS) en 7 casos. El éxito técnico fue del 100% (17 pacientes), mientras que el éxito clínico fue de 70,6% (12 pacientes). Las complicaciones ocurrieron en 41,2%: infección de colección (2 casos), perforación, sangrado en zona de drenaje, obstrucción de prótesis plástica, migración de prótesis al interior de colección y al lumen gástrico (1 caso cada uno). El manejo quirúrgico de éstas complicaciones fue necesaria en 3 casos, mientras que en los otros 4 casos solo requirió manejo médico - endoscópico. Conclusiones: los drenajes guiados por ecoendoscopía de las colecciones liquidas peripancreáticas tienen alta tasa de éxito técnico y clínico con reducido porcentaje de complicaciones.
ABSTRACT Introduction: Endoscopic ultrasound (EUS) guided drainage is considered the best option for peripancreatic fluid collections drainage. There are no previous reports in our country of this type of endoscopic therapy. Objectives: To detail the characteristics, efficacy and safety of EUS-guided drainage of peripancreatic fluid collections at Edgardo Rebagliati Martins National Hospital. Materials and methods: We carried out a retrospective cross-sectional study of all patients who underwent EUS-guided drainage of symptomatic peripancreatic fluid collections. Demographics, procedure-related endosonographic features and devices used were analyzed. We assessed the effectiveness with technical and clinical success rate. Clinical safety was assessed based on major immediate and delayed adverse events. Basic descriptive statistics was used. Results: A total of 17 patients (9 women, 52.9% and 8 men, 47.1%) with peripancreatic fluid collections (10 pseudocysts and 7 walled-off necrosis) underwent EUS-guided drainage. The median age of the patients was 59 years (range 26 - 72 years). The mean diameter of the fluid collections was 14.8 cm (range 8-24 cm). Transgastric route was used in 16 cases (94.1%) and transduodenal route in 1 case (5.9%). Plastic stent (6 cases), biliary self expanding metal stent (4 cases) and lumen apposing stent (7 cases) were used. The technical success rate was 100% (17 patients), while clinical success rate was 70.6% (12 patients). Adverse events occurred in 41.2%: infection (2 cases), perforation, bleeding, plastic stent occlusion, stent migration into the collection cavity and out of the collection cavity (1 case each one). Surgical management of adverse events was necessary in 3 cases, while the 4 other cases only required medical - endoscopic management.

RESUMEN El empleo del contraste endovenoso permite aumentar la capacidad diagnostica de la ecoendoscopía en muchas condiciones patológicas de forma no invasiva, mediante la evaluación de patrones de realce en tiempo real (hipo, iso e hipercaptación), permitiendo a su vez definir diagnósticos diferenciales o predecir diagnósticos histológicos con alta precisión por medio de la caracterización de la vascularidad o microvasculatura de un órgano o lesión. Sin embargo, su empleo en nuestro medio está limitado por no contar con estos medios de contraste. Reportamos tres casos de ecoendoscopía contrastada realizada en patología pancreática realizada en nuestro hospital, en el que se describe la utilidad en el diagnóstico y manejo de lesiones sólidas y quísticas del páncreas.
ABSTRACT The intravenous contrast (IV) allows for improving the diagnostic accuracy of echoendoscopy for many pathologic conditions. IV contrast provides a non-invasive method that through the use of real-time enhancement patterns (hypo, iso, and hypercaptation), a highly accurate histological diagnosis can be made by characterizing the microvasculature of an organ or a lesion. However, the lack of availability of IV contrast limited its use in our setting. We reported three cases of endoscopic ultrasound with IV contrast performed in the pancreatic department of National Hospital Eduardo Rebagliati Martins in Lima, Peru. We described the effectiveness of IV contrast in the diagnosis and the management of solid and cystic lesions in the pancreas.

Resumen Introducción: La cirugía laparoscópica es la vía de abordaje de elección para el tratamiento de múltiples patologías abdominales, sin embargo, su desarrollo en la cirugía hepato-bilio-pancreática (HBP) ha sido más lento y heterogéneo. Objetivo: Presentar los resultados de la implementación y desarrollo de un programa de cirugía HBP laparoscópica en el Hospital de Regional de Talca. Materiales y Método: Estudio de serie de casos que incluye a todos los pacientes operados por una patología HBP por vía laparoscópica como acceso a la cavidad abdominal en el Hospital Regional de Talca entre el 1 de junio de 2014 y el 30 de junio de 2016. Resultados: Fueron 42 pacientes, 25 (59,5%) de sexo femenino. La mediana de edad fue 58 años (IQ25-75 38-64 años). 22 (52,4%) tuvo una cirugía abdominal previa en la mayoría de ellos por vía abierta. 22 (52,4%) pacientes fueron intervenidos por patología maligna. La indicación más frecuente fue la cirugía radical por cáncer de vesícula biliar en 10 (23,8%) casos y la hidatidosis hepática (HH) en 7 (16,7%). 1 (2,4%) paciente portador de una HH requirió de una conversión a laparotomía. 5 (11,9%) presentaron alguna morbilidad posoperatoria, 2 de ellos > III de Clavien. La mediana de recuperación funcional fue de 1 día (1-2) y la de estadía posoperatoria de 3 días (3-4). No hubo mortalidad a 90 días. Con una mediana de seguimiento de 26,5 (18-33) meses, 4 (19%) de los 21 pacientes oncológicos intervenidos con intención curativa presentaron recurrencia de la enfermedad, la mayoría de ellos sistémica y el 95% está libre de recurrencia a los 24 meses. Conclusiones: La implementación y el desarrollo de la cirugía hepato-bilio-pancreática (HBP) por vía laparoscópica puede efectuarse en hospitales de referencia regional con los mismos estándares y resultados internacionales.
Introduction: Laparoscopic surgery is the preference access for the treatment of various abdominal pathologies, however, its development in hepato-biliary-pancreatic (HBP) surgery has been slower and heterogeneous. Aim: Present the results of the implementation and development of a laparoscopic HBP surgery program at the Regional Hospital of Talca. Materials and Method: Case series study in which were included all patients submitted to laparoscopic surgery for treatment of HPB pathology as access to the abdominal cavity in the Regional Hospital of Talca between June 1, 2014 and June 30, 2016. Results: There were 42 patients, 25 (59.5%) female. The median age was 58 years (IQ25-75 38-64 years). 22 (52.4%) had previous abdominal surgery in most of them by open route. 22 (52.4%) patients were operated on for malignant pathology. The most frequent indication was radical surgery for gallbladder cancer in 10 (23.8%) cases and hepatic hydatidosis (HH) in 7 (16.7%). 1 (2.4%) patient carrying a HH required a conversion to laparotomy. 5 (11.9%) presented some postoperative morbidity, 2 of them > Clavien III. The median functional recovery was 1 day (1-2) and the postoperative stay was 3 days (3-4). There was no mortality at 90 days. With a median follow-up of 26.5 (18-33) months, 4 (19%) of the 21 oncological patients operated on with curative intent presented recurrence of the disease, most of them systemic and 95% free from recurrence at 24 months. Conclusions: Implementation and development of HBP surgery by laparoscopy is feasible and it can be performed in regional referral hospitals with the same international standards and results.

Objective: To demonstrate the interaction between obstructive sleep apnea/hypopnea syndrome, insulin resistance, and non-alcoholic fatty pancreatic disease through the signaling pathway diagram. Methods: To investigate the involvement of metabolic signaling pathway, a search was performed using the Kyoto Encyclopedia of Genes and Genomes. The signaling pathway mapping was performed using the automatic annotation server of this encyclopedia. The Modeller 9.19 package was used to predict 3-dimensional structures based on the homology modeling protocol. The signaling pathway map was performed using PathVisio software, which is a free available signaling pathway drawing software. Based on the 3-dimensional structures, we have designed several peptide activators of the signaling pathway of non-alcoholic fatty pancreatic disease. Results: The contigs were taken from the Kyoto Encyclopedia of Genes and Genomes database and their mapped transcription represented the signaling pathway of the main biomolecules that triggered non-alcoholic fatty pancreatic disease. The interaction between obstructive sleep apnea/hypopnea syndrome, insulin resistance, and inflammatory factors contributes to the possible development of fatty infiltration of pancreas, leading to the loss of function of the pancreatic ß-cells, and even to the development of other metabolic diseases. Conclusion: The interaction between obstructive sleep apnea/hypopnea syndrome and insulin resistance demonstrated through the signaling pathway contributes to the possible development of non-alcoholic fatty pancreatic disease.

Objetivo: Demonstrar a interação entre a síndrome de apneia/ hipopneia obstrutiva do sono, a resistência à insulina e a doença pancreática gordurosa não alcoólica considerando o desenho de uma via de sinalização. Métodos: Para avaliar o envolvimento da via de sinalização metabólica, realizou-se uma pesquisa usando a Enciclopédia de Genes e Genomas de Kyoto. O mapeamento da via de sinalização foi realizado com o servidor de anotação automático desta enciclopédia. O software MODELLER 9.19 foi usado para prever estruturas tridimensionais, com base no protocolo de modelagem por homologia. O desenho da via de sinalização foi realizado por meio do programa PathVisio, um software de domínio público para desenho de via de sinalização. Com base nas estruturas tridimensionais, desenhamos os vários ativadores peptídicos da via de sinalização da esteatose pancreática. Resultados: Os contigs foram retirados do banco de dados da Enciclopédia de Genes e Genomas de Kyoto, e sua transcrição mapeada representou a via de sinalização das principais biomoléculas que desencadearam doença pancreática gordurosa não alcoólica. A interação entre síndrome de apneia/hipopneia obstrutiva do sono, resistência à insulina e fatores inflamatórios contribuiu para o possível desenvolvimento de infiltração gordurosa do pâncreas, levando à perda de função das células beta pancreáticas e até mesmo ao desenvolvimento de outras doenças metabólicas. Conclusão: A interação entre síndrome de apneia/hipopneia obstrutiva do sono e resistência à insulina demonstrada pela via de sinalização contribui para o possível desenvolvimento de doença pancreática gordurosa não alcoólica.

BACKGROUND/AIMS: In this study, we aimed to evaluate the predictive value of localized stenosis of the main pancreatic duct (MPD) for early detection of pancreatic cancer.METHODS: Among 689 patients who underwent endoscopic retrograde pancreatography from January 2008 to September 2018, 19 patients with MPD findings were enrolled. These patients showed findings for indicating suspicious pancreatic cancer at an early stage (FiCE); FiCE was defined as a single, localized stenosis in the MPD without a detectable mass (using any other imaging methods) and without other pancreatic diseases, such as definite chronic pancreatitis, intraductal papillary mucinous neoplasm, and autoimmune pancreatitis. Final diagnoses were established by examining resected specimens or through follow-up examinations after an interval of >5 years.RESULTS: Among 19 patients with FiCE, 11 underwent surgical resection and 8 were evaluated after a >5-year observation period. The final diagnosis of the MPD stenosis was judged to be pancreatic cancer in 9 patients (47%), including 3 with intraepithelial cancer, and to be a non-neoplastic change in 10. The sensitivity, specificity, and accuracy of preoperative pancreatic juice cytology were 75%, 100%, and 88%, respectively.CONCLUSIONS: The predictive value of FiCE for pancreatic cancer prevalence was 47%. Histological confirmation with pancreatic juice cytology is necessary before surgical resection.

OBJECTIVE@#To analyze clinical manifestations, diagnosis and treatment of annular pancreas in neonates.@*METHODS@#Clinical data of 114 neonates with annular pancreas admitted in the Children's Hospital of Zhejiang University from January 2009 to December 2018 were reviewed. The demographic parameters (gestational age, birth weight), clinical manifestations, onset time, results of antenatal examination, associated anomalies, radiological findings, operations, postoperative complications were analyzed.@*RESULTS@#One hundred and two cases were examined by abdominal echography, in which 68 cases showed duodenal obstruction, 4 cases showed annular pancreas. Plain abdomen X-ray examination performed in 113 cases before operation, 76 cases presented double-bubble sign, 12 cases presented single-bubble sign and 5 cases had high-position intestinal obstruction. Upper gastrointestinal radiography (UGI) was performed in 103 cases, which suggested duodenal obstruction in 102 cases. Operations were performed in all cases, of which 69 cases were operated under laparoscopy including 1 case converted to open laparotomy. The mean fasting time after surgery was (7.8±2.7) d, and the mean length of hospital stay was (16.9±10.1) d. Five patients had postoperative complications. The incidence of postoperative complications in antenatal abnormal group was lower than that in the antenatal non-abnormal group (<0.05); the average fasting time in laparoendscopic surgery group was shorter than that in traditional laparotomy group (<0.05).@*CONCLUSIONS@#Neonates with recurrent vomiting early after birth should be highly suspected to have annular pancreas. The fetal chromosome examination should be performed with abnormal antenatal screening. Surgery is the only effective way to diagnose and treat annular pancreas, and laparoscopic surgery could be the first choice for experienced doctors.
