ABSTRACT

Introducción. En las hernias paraesofágicas tipo IV se produce la herniación del estómago junto a otros órganos abdominales. La herniación del páncreas es muy infrecuente.Caso clínico. Varón de 57 años que acude por dolor torácico, disnea e intolerancia al decúbito. En la tomografía computarizada toracoabdominal se observa hernia diafragmática que contiene colon transverso, intestino delgado y páncreas, con reticulación de la grasa alrededor del mismo, compatible con pancreatitis aguda. Conclusión. La asociación de hernia hiatal con páncreas herniado y pancreatitis es extremadamente infrecuente. El diagnóstico se estableció mediante tomografía computarizada y el tratamiento fue conservador, con cirugía diferida de la hernia de hiato.


Introduction. In type IV paraesophageal hernias, the stomach is herniated along with other abdominal organs. Herniation of the pancreas is very rare. Clinical case. A 57-year-old man presented with chest pain, dyspnea, and intolerance to decubitus. The thoracoabdominal computed tomography shows a diaphragmatic hernia containing the transverse colon, small intestine and pancreas, with reticulation of fat around it, compatible with acute pancreatitis. Conclusion. The association of hiatal hernia with herniated pancreas and pancreatitis is extremely rare. The diagnosis was established by computerized tomography and the treatment was conservative, with delayed surgery for the hiatal hernia.

ABSTRACT

Resumen El adenocarcinoma ductal de páncreas es una enfermedad agresiva asociada con pobres resultados de supervivencia a largo plazo. La resección quirúrgica y los nuevos tratamientos oncológicos pe rioperatorios han logrado mejorar la supervivencia de estos pacientes en la experiencia internacional. En este estudio retrospectivo se analiza la supervivencia global y la libre de enfermedad de todos los pacientes operados por cáncer de páncreas en el Hospital Italiano de Buenos Aires de enero 2010 a enero 2020. Se identificaron 242 pacientes con resecciones pancreáticas por adenocarcinoma de páncreas o carcinoma indiferenciado. La supervivencia global mediana fue de 22.8 meses (IC 95%: 19.5-29) y la tasa de supervivencia global a 1, 3 y 5 años fue de 72%, 32.5% y 20.8% respectivamente. La supervivencia libre de enfermedad mediana fue de 13.8 meses (IC 95%: 12-17.6) y la tasa de supervivencia libre de enfermedad a 1, 3 y 5 años fueron de 56.1%, 21.8% y 19.4% respectivamente. El grupo de pacientes que logró completar el tratamiento adyuvante mostró una mayor supervivencia global (p<0.0001).


Abstract Pancreatic cancer is an aggressive disease associated with poor results regarding long term survival. Surgical treatment along with new onco logic treatments have improved the survival of these patients in international experience reports. The aim of this study was to describe overall survival and disease-free survival after pancreatectomy for pancreatic ductal adenocarcinoma. A retrospective study of consecutive patients undergoing pancreatic resection due to PDAC or undifferentiated carcinoma from January 2010 to January 2020 in a single tertiary center was performed. Overall, 242 patients underwent complete pancreatic resections for pancreatic ductal adenocarcinoma or undifferentiated carcinoma. Median overall survival was 22.8 months (95% CI: 19.5-29) and survival at 1, 3 and 5 years were 72%, 32.5% and 20.8% respectively. The median disease-free survival was 13.8 months (95% CI: 12-17.6) and 1, 3- and 5-years disease-free survival were 56.1%, 21.8% and 19.4% respectively. The groups of patients that completed adjuvant treatment showed a better overall survival (p < 0.0001).

ABSTRACT

Introducción: El páncreas ectópico es la segunda anomalía congénita pancreática más frecuente después del páncreas divisum. Fue descrito por primera vez en 1729 por Schultz y se define como la presencia de tejido pancreático que carece de comunicación anatómica o vascular con el cuerpo principal del páncreas. La localización más frecuente es en el estómago (25 - 38 por ciento), seguido de duodeno, yeyuno e íleon. El 40 por ciento de los casos son sintomáticos y es más frecuente su presentación en varones en torno a la 5ª y 6ª década de la vida. Objetivo: Presentar un caso de páncreas ectópico diagnosticado a través de un estudio histológico tras realizada la cirugía. Presentación de caso: Presentamos el caso de una paciente compatible con hipoglucemia y cuyo estudio definitivo mostró la presencia de tejido pancreático ectópico en estómago, con resolución completa de los síntomas tras tratamiento quirúrgico. La anatomía patológica mostró una lesión nodular tumoral benigna (2,5 cm), constituida por tejido pancreático heterotópico, con presencia de páncreas exocrino con acinos. Páncreas endocrino con presencia de islotes de Langerhans y componente epitelial con ductos. Afectación desde la submucosa hasta la subserosa, con una pared muscular propia con hiperplasia muscular en relación a la heterotopía pancreática. La mucosa gástrica mostraba inflamación crónica leve con escasos folículos linfoides. Conclusiones: La presencia de páncreas ectópico es una entidad poco frecuente, pero a tener en cuenta en pacientes con clínica de hipoglucemia, una vez descartadas otras causas. No existe consenso con respecto a indicaciones en el manejo de lesiones pequeñas y asintomáticas, por lo que se recomienda individualizar cada caso teniendo en cuenta el tamaño, la localización y el tipo histológico(AU)


Introduction: Ectopic pancreas is the second most frequent congenital anomaly after pancreas divisum. It was described for the first time in 1729 by Schultz and it is defined as the presence of pancreatic tissue with no anatomical or vascular communication with the main body of pancreas. The most common location is in the stomach (25-38 percent), followed by the duodenum, jejunum and ileum ones. 40 percent of the cases are symptomatic and is more frequent their presentation in males in the fifth or sixth decade of life. Objective: To present a case of ectopic pancreas diagnosed through a histological study after surgery. Case presentation: Case of a patient with clinical features compatible with hypoglycemia that after being studied showed the presence of ectopic pancreatic tissue in the stomach, with a complete solution of the symptoms after surgical treatment. The pathological anatomy showed a benign tumor nodular lesion (2.5 cm), made up of heterotopic pancreatic tissue, with the presence of exocrine pancreas with acini. Endocrine pancreas with the presence of islets of Langerhans and epithelial component with ducts. Involvement from the submucosa to the subserosa, with a proper muscular wall with muscular hyperplasia in relation to pancreatic heterotopia. The gastric mucosa showed mild chronic inflammation with few lymphoid follicles. Conclusions: The presence of ectopic pancreas is a rare condition, but it should be taken into account in patients with clinical features of hypoglycemia once ruled out other causes. There is no consensus in regards to the indications for the management of small and asymptomatic lesions, so, it is recommended to individualize each case taking into account the size, location and histological type(AU)

ABSTRACT

Antecedentes: Los quistes hidatídicos primarios pancreáticos son raros por no decir excepcional, siendo en las grandes series su incidencia apenas entre el 0,2 % al 0,3%. Lugar de Aplicación: Servicio de Cirugía General "Pablo Luis Mirizzi" del Hospital Nacional de Clínicas, Sanatorio Allende y Clínica Privada Caraffa de Córdoba. Diseño: Cooperativo, retrospectivo. Material y Método: Entre diciembre de 2000 y diciembre del 2019 han sido tratados quirúrgicamente 9 pacientes con hidatidosis primaria de páncreas, siendo 5 del sexo masculino y los cuatro restantes del sexo femenino, con una edad promedio de 39,4 años. En relación con la clínica, todos los pacientes tenían dolor abdominal, acompañado de vómitos, distensión abdominal y fiebre. En tres presentaban una masa abdominal palpable. A todos se les solicito laboratorio y pruebas de hidatidosis, destacándose en 6 de los 9 pacientes dieron positivo. Resultados: Se estudiaron a todos los pacientes con una ecografía abdominal, TC de abdomen y en un paciente una CPRMN más RMN de abdomen. Se realizaron previamente el tratamiento con abendazol antes del tratamiento quirúrgico en todos los casos. En relación con el tratamiento quirúrgico, se llevó a cabo el destechamiento y drenaje del quiste con la técnica de Mabit-Lagrot en 6 oportunidades y en 3 con la Técnica de Goinard. Conclusión: La localización de los quistes hidatídicos en el páncreas es rara. El diagnóstico se basa fundamentalmente en los estudios por imágenes, además si se correlacionan con la epidemiología y la serología hidatídica positiva. El tratamiento del quiste hidatídico de páncreas es quirúrgico.


Background: Pancreatic primary hydatic cysts are rare not to say exceptional, with their incidence in large series being only 0.2% to 0.3%. Setting: General Surgery Service "Pablo Luis Mirizzi" of the National Hospital of Clinics, Allende Sanatorium and Caraffa Clinic of Córdoba. Design: Retrospective and cooperative. Methods: Between December 2000 and December 2019, 9 patients with primary pancreatic hydatic have been treated surgically, with 5 of the male sex and the remaining four of the female sex, with an average age of 39.4 years. In relation to the clinic, all patients had abdominal pain, accompanied by vomiting, bloating and fever. In three they had a palpable abdominal mass. All were asked for laboratory and hydatic tests, highlighting in 6 of the 9 patients tested positive. Results: All patients with abdominal ultrasound, abdominal CT and a patient were studied for CPRMN plus MRI of the abdomen. Abendazole was previously treated prior to surgical treatment in all cases. In relation to surgical treatment, the traditional unroofing and drainage of the cyst was carried out with the Mabit-Lagrot technique in 6 opportunities and in 3 with the Goinard Technique. Conclusions: The location of hydatic cysts in the pancreas is rare. Diagnosis is based primarily on imaging studies, in addition if they correlate with epidemiology and positive hydatic serology. Treatment of the pancreas hydatic cyst is surgical

ABSTRACT

Several species of the Myrcia genus have been used in folk medicine to treat diabetes. Therefore, the aim of this work was to investigate the inhibitory activity of α-glucosidase and pancreatic lipase in the crude extract (EBF) and in the ethyl acetate fraction (FFA) of Myrcia hatschbachii, as well as to identify isolated phenolic compounds and to evaluate the antioxidant property and preliminary in vitro toxicity against Artemia salina. EBF (IC50: 3.21 µg/mL) and FFA (IC50: 1.14 µg/mL) showed inhibitory activity superior to acarbose (IC50: 193.65 µg/mL). In addition, they showed inhibitory effects of pancreatic lipase (IC50: 556.58 µg/mL for EBF and 532.68 µg/mL for FFA), antioxidant potential, absence of preliminary toxicity and presence of gallic andellagic acids in FFA. The relevant results in the inhibition of α-glucosidase and pancreatic lipase motivate new studies for the development of herbal medicines that assist in the treatment of diabetic patients.


Varias especies del género Myrcia se han utilizado en la medicina popular para tratar la diabetes. Por lo tanto, el objetivo de este trabajo fue investigar la actividad inhibitoria de la α-glucosidasa y la lipasa pancreática en el extracto crudo (EBF) y en la fracción de acetato de etilo (FFA) de Myrcia hatschbachii, así como identificar compuestos fenólicos aislados y evaluar la propiedad antioxidante y toxicidad in vitro preliminar contra Artemia salina. EBF (IC50: 3.21 µg/mL) y FFA (IC50: 1.14 µg/mL) mostraron una actividad inhibitoria superior a la acarbosa (IC50: 193.65 µg/mL). Además, mostraron efectos inhibitorios de la lipasa pancreática (IC50: 556.58 µg/mL para EBF y 532.68 µg/mL para FFA), potencial antioxidante, ausencia de toxicidad preliminar y presencia de ácidos gálico y elágico en FFA. Los resultados relevantes en la inhibición de la α-glucosidasa y la lipasa pancreática motivan nuevos estudios para el desarrollo de medicamentos a base de hierbas que ayudan en el tratamiento de pacientes diabéticos.

ABSTRACT

Introducción: la diabetes mellitus (DM) se considera un factor de riesgo para el desarrollo de adenocarcinoma ductal de páncreas (ACDP). Objetivos: describir la prevalencia de DM y glucemia en ayuno alterada (GAA) al diagnóstico de ACDP en pacientes asistidos en un centro de referencia gastroenterológico; analizar las diferencias en las características personales y nutricionales en pacientes con ACDP y DM, ACDP y GAA, y ACDP sin DM ni GAA; establecer el tiempo transcurrido desde el diagnóstico de DM hasta diagnosticar ACDP. Materiales y métodos: de octubre de 2019 a marzo de 2020 se revisaron 465 historias clínicas de las Secciones Oncología y Nutrición de pacientes >18 años con diagnóstico de ACDP. Resultados: se registraron 171 historias clínicas (36,7%) con ACDP y DM, y 294 (63,2%) con ACDP sin DM. En el 45,1% de las primeras, el intervalo entre el diagnóstico de DM y el de ACDP fue <1 año, y en el 17,65%, 15,69% y 21,57% los lapsos correspondieron a 1 y 5 años, entre 5 y 10 años y >10 años respectivamente. Conclusiones: la prevalencia de DM en ACDP fue superior a la registrada en la población general (37% vs 12,7%), siendo del 45,10% cuando se presentó dentro del primer año del diagnóstico oncológico. Nuestros resultados concuerdan con la bibliografía internacional que relaciona la DM de reciente diagnóstico como factor asociado a la presencia de ACDP por factores de riesgo compartidos, variables fisiopatológicas de la DM o a consecuencia de la terapéutica farmacológica de la misma.


Introduction: diabetes mellitus (DM) is considered to be a risk factor for the development of pancreatic ductal adenocarcinoma (PDAC). Objectives: describe the prevalence of DM and of impaired fasting glucose (IFG) at the diagnosis of PDAC, among patients assisted in a gastroenterological reference center. Analyze differences in personal and nutritional characteristics in patients with both PDAC and DM; with both PDAC and IFG; and with PDAC but neither DM nor IFG. Determine the time lapse between the diagnosis of DM and the diagnosis of PDAC. Materials and methods: between October 2019 and March 2020, we analyzed 465 clinical records of PDAC-diagnosed patients over 18 years, from Oncology and Nutrition Sections. Results: 171 clinical records (36.7%) showed both PDAC and DM; 294 clinical records (63.2%) showed PDAC but not DM. In 45.1% of the former, the interval between the diagnosis of DM and that of PDAC was <1 year, and in 17.65%, 15.69% and 21.57%, the lapses corresponded to 1 and 5 years, between 5 and 10 years y >10 years, respectively. Conclusions: the prevalence of DM in PDAC patients (37%) is higher than that registered in the overall population (12.7%), reaching a 45.10% when detected during the first year of oncological diagnosis. Our results match the international literature relating recently-diagnosed DM with the presence of PDAC, as effect of shared risk factors between both diseases, or DM pathophysiology factors, or DM pharmacological therapeutic

ABSTRACT

Resumen La pancreatitis aguda es una patología inflamatoria del páncreas que se caracteriza por dolor abdominal y elevación de los niveles séricos de amilasa. Desde el punto de vista imagenológico, se la estudia con tomografía computada (TC), siendo esa la modalidad de elección para evaluar la extensión y la localización de las complicaciones. Según la gravedad, el tiempo de evolución y la extensión, hay distintos tipos de complicaciones y una variedad de hallazgos en TC.


Abstract Acute pancreatitis is an inflammatory pathology of the pancreas characterized by abdominal pain and elevated levels of serum amylase. In radiology, it is studied with computed tomography (CT), which is the preferred method to evaluate the extent and location of complications. Depending on the severity, time of evolution, and extent, there are different types of complications and a variety of findings on the CT scan.

ABSTRACT

RESUMEN Antecedentes: Debido a la mejoría de los métodos diagnósticos, la incidencia de la neoplasia papilar mucinosa intraductal del páncreas (NPMI) ha aumentado en los últimos años. Objetivo: Presentar la experiencia en el manejo alejado de pacientes con NPMI en un centro de referencia. Material y métodos : Se realizó análisis retrospectivo de pacientes que consultaron al Servicio de Ci rugía General y HPB del Hospital Universitario Fundación Favaloro, por patología pancreática tumo ral entre enero de 2010 y diciembre de 2019. Los pacientes se clasificaron en 2 grupos: A) aquellos con diagnóstico en consultorio de NPMI y B) aquellos en los que la NPMI fue un hallazgo en la pieza quirúrgica (B). Resultados: Ochenta y seis pacientes fueron analizados: 79 (90%) se incluyeron en el grupo A y 7 en el grupo B. De los pacientes del grupo A, en 57 casos (66%) se decidió conducta expectante y seguimiento (AS). De los 22 pacientes restantes, 18 fueron operados (29%) (AC) y 4 tienen la cirugía pendiente. Para el grupo A, la supervivencia a los 5 años fue de 89% para el grupo AS, de 86% en grupo AC, y del 43% para el grupo B (Breslow 0,001, Log-Rank 0,001 vs. grupo A). Conclusión: El diagnóstico y manejo de la NPMI está hoy estandarizado, en las tipo I y III está indicada cirugía, la tipo II debe seguirse por riesgo de malignización; cuando se le indica cirugía, la supervivencia a largo plazo debe ser similar a la del grupo en seguimiento.


ABSTRACT Background: The incidence of intraductal papillary mucinous neoplasm (IPMN) of the pancreas has increased over the past years along with the development of diagnostic imaging tests. Objective: The aim of this study is to describe our experience on long-term management of patients with IPMNs in a reference center. Material and methods: We conducted a retrospective and descriptive analysis of patients with pancreatic neoplasms followed-up at the Department of General Surgery and Hepato-Biliary Surgery, Hospital Universitario Fundación Favaloro, between January 2010 and December 2019. The patients were classified into 2 groups: group A (diagnosis of IPMN made in the outpatient clinic), and group B (diagnosis of IPMN in the pathological examination). Results: Eighty-six patients were analyzed: 79 (90%) in group A and 7 in group B. In group A, a watchful waiting with monitoring (AM) was decided in 57 cases (66%). Of the remaining 22 patients, 18 (29%) patients underwent surgery (AS) and 4 are waiting for surgery. Survival at 5 years was 89% in group AM, 86% in group AS and 43% in group B (Breslow 0.001, log-rank test 0,001 vs. group A). Conclusion : The diagnosis and management of IPMNs is currently standardized. Surgery is indicated in MD-IPMN and mixed type IPMN. Patients with BD-IPMN type should be monitored due to the risk of malignant transformation. When surgery is indicated, long-term survival should be similar to that of the surveillance group.

ABSTRACT

Introducción. La incidencia de lesiones traumáticas del páncreas es baja debido a su localización retroperitoneal, y las lesiones aisladas son excepcionales debido a la proximidad del páncreas a otros órganos y estructuras vasculares. Caso clínico. Presentamos el caso de un varón de 21 años con lesión aislada del páncreas tras traumatismo abdominal cerrado, que precisó manejo quirúrgico. Discusión. Las lesiones pancreáticas aisladas secundarias a traumatismo son raras, pero debemos tenerlas en cuenta en un paciente politraumatizado. Su diagnóstico precoz y manejo adecuado son cruciales para evitar el desarrollo de complicaciones


Introduction. The incidence of traumatic injuries to the pancreas is low due to its retroperitoneal location, and isolated injuries are rare due to the proximity of the pancreas to other vascular organs and structures. Clinical case. We present the case of a 21-year-old man with an isolated lesion of the pancreas after blunt abdominal trauma, which required surgical management.Discussion. Isolated pancreatic injuries secondary to trauma are rare but must be taken into account in a multiple trauma patient. Its early diagnosis and proper management are crucial to avoid the development of complications

ABSTRACT

Resumen La endosonografía endoscópica es una alternativa que sirve como guía para la realización de derivaciones biliodigestivas en los casos en los que la colangiopancreatografía retrógrada endoscópica (CPRE) ha fallado. Se han descrito técnicas como la coledocoduodenostomía o coledocoantrostomía guiadas por ultrasonografía endoscópica (USE). Se describe el caso de una paciente de 72 años con adenocarcinoma de páncreas, compromiso portal y de paredes duodenales, en quien se usó la CPRE para intentar una derivación paliativa y fue fallida, por lo cual se realizó la colocación de un stent metálico guiado por endosonografía endoscópica, con adecuada respuesta clínica al tratamiento. En conclusión, el procedimiento es seguro y la endosonografía es una vía alterna efectiva en los casos de CPRE fallidas para lograr derivaciones biliares en casos de obstrucción de la vía biliar de origen maligno.


Abstract Endoscopic endosonography is an alternative to guide biliodigestive shunting in cases where endoscopic retrograde cholangiopancreatography (ERCP) has failed. Techniques such as choledoduodenostomy or choledochoantrostomy guided by endoscopic ultrasonography have been described. This is the case of a 72-year-old patient with pancreatic adenocarcinoma, portal vein and duodenal wall involvement, in whom ERCP to try a palliative shunt failed. Therefore, a metal stent was placed using endoscopic endosonography, with adequate clinical response to the procedure and treatment. It is concluded that the procedure is safe and that endosonography is an effective alternative in cases of ERCP failure to achieve biliary bypass in cases of malignant biliary obstruction.

ABSTRACT

RESUMO - RACIONAL: Apesar da recomendação atual que o cistoadenoma seroso deva ser tratado de forma conservadora, significativa parte dos pacientes com essa condição ainda é operada por dúvida diagnóstica. OBJETIVO: Analisar causas da baixa acurácia diagnóstica do cistoadenoma seroso. MÉTODOS: Estudo retrospectivo de portadores de cistoadenoma seroso de um banco de dados de dois ambulatórios de cirurgia hepatopancreaticobiliar entre 2006 e 2020. Foram incluídos pacientes com lesões típicas de cistoadenoma seroso aos exames de imagem (tomografia computadorizada, ressonância magnética e ecoendoscopia) e pacientes que o anatomopatológico confirmasse esse diagnóstico. RESULTADOS: 27 pacientes foram incluídos. 85,18% eram do sexo feminino. A idade média foi de 63,4 anos. Apenas um apresentava sintomas típicos de pancreatite. A Ressonância magnética foi o exame mais realizado (62,9%). A lesão era única em 88,9% e o tamanho médio foi 4 cm. O aspecto típico microcístico foi encontrado em 66,6% dos casos, os demais foram considerados atípicos. A ecoendoscopia foi realizada em 29,6%. O valor médio de antígeno carcinoembrionário nos pacientes submetidos à punção do cisto foi de 198,25 ng/mL. O tratamento cirúrgico foi realizado em 10 casos (37%). Em 7, a causa cirúrgica foi a suspeita do cistoadenoma mucinoso mediante identificação de lesões atípicas (unilocular com ou sem septos e macrocística). Em 2, a suspeita de neoplasia papilar intraductal mucinosa com "fatores preocupantes" foi a indicação cirúrgica. O último foi submetido à cirurgia por lesão de aspecto sólido e suspeita de câncer. O índice de complicações > ou = Clavien-Dindo 2 foi 30%, o índice de fístula pancreática clinicamente relevante (B e C) foi 30%. A mortalidade foi nula. CONCLUSÃO: A apresentação morfológica atípica do cistoadenoma seroso, particularmente lesões uniloculares e macrocísticas, é a principal responsável pela indicação cirúrgica. Apenas a implementação de novos, eficientes e reprodutíveis métodos diagnósticos poderá reduzir o número de cirurgias desnecessárias nesses pacientes.


ABSTRACT - BACKGROUND: Many patients with serous cystadenoma of the pancreas (SCP) underwent surgery due to diagnostic doubt. AIM: The aim of this study was to analyze the causes of low accuracy in diagnosing SCP. METHODS: This is a retrospective study of patients with SCP from a database of two hepatopancreatic biliary surgery outpatient clinics between 2006 and 2020. Patients with typical SCP lesions in imaging exams (e.g., tomography, magnetic resonance imaging [MRI], and endoscopic ultrasound [EUS]) and patients whose pathological testing confirmed this diagnosis were included. RESULTS: A total of 27 patients were included in this study. Most patients were women (85.18%), and the mean age was 63.4 years. Only one patient had typical pancreatitis symptoms. MRI was the most performed method (62.9%). The lesion was single in 88.9%, and the average size was 4 cm. The typical microcystic aspect was found in 66.6%. EUS was performed in 29.6% of cases. The mean carcinoembryonic antigen value in patients undergoing cyst puncture was 198.25 ng/mL. Surgical treatment was performed in 10 cases (37%). The cause of surgery in seven of these cases was due to a suspicion of mucinous cystadenoma based on an identification of atypical lesions (unilocular with or without septa and macrocystic) in imaging exams. A suspicion of intraductal papillary mucinous neoplasm with "worrying factors" was the indication for surgery in two cases. The last case underwent surgical treatment for a solid-looking lesion which was suspected of cancer. The complication rate ≥Clavien-Dindo 2 was 30%, and the clinically relevant pancreatic fistula rate (B and C) was 30%. Mortality was nil. CONCLUSION: The atypical morphological presentation of SCP, particularly unilocular and macrocystic lesions, is the main indication for surgery. Only the implementation of new, efficient, and reproducible diagnostic methods can reduce the number of unnecessary surgeries among these patients.

ABSTRACT

A heterotopia pancreática é definida como a presença de tecido pancreático em localização topográfica anômala. Essa patologia pode acometer variadas estruturas da cavidade abdominal, mas raramente manifesta-se na vesícula biliar. Até o momento, menos de 40 casos de heterotopia pancreática em vesícula biliar foram relatados na literatura médica. Apresentamos um caso de uma mulher de 25 anos, que realizou uma colecistectomia videolaparoscópica por colelitíase, com exame anatomopatológico que identificou uma heterotopia pancreática. Apesar de rara, a doença deve ser considerada em pacientes com sintomatologia de doenças da via biliar e de doenças pancreáticas e sem diagnóstico após uma investigação de rotina, tendo em vista que o tecido pancreático ectópico está sujeito às mesmas alterações patológicas, manifestações clínicas e complicações encontradas no próprio pâncreas. (AU)


Heterotopic pancreas is defined as the presence of pancreatic tissue at an anomalous location. This condition may affect multiple structures in the abdominal cavity but rarely appears in the gallbladder. To date, fewer than 40 cases of heterotopic pancreas in the gallbladder have been reported in the medical literature. We present a case of a 25 year-old woman who underwent a laparoscopic cholecystectomy for cholelithiasis, with a pathology test that detected heterotopic pancreas. Despite its rarity, this disease must be considered in cases of corresponding symptoms without a diagnosis after a routine evaluation, considering that ectopic pancreatic tissue is exposed to the same pathological alterations, clinical manifestations, and complications found in the pancreas.

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

Objective To determine the appropriate averaging strategy for pancreatic perfusion datasets to create images for routine reading of insulinoma.Methods Thirty-nine patients undergoing pancreatic perfusion CT in Peking Union Medical College Hospital and diagnosed as insulinoma by pathology were enrolled in this retrospective study.The time-density curve of abdominal aorta calculated by software dynamic angio was used to decide the timings for averaging.Five strategies,by averaging 3,5,7,9 and 11 dynamic scans in perfusion,all including peak enhancement of the abdominal aorta,were investigated in the study.The image noise,pancreas signal-to-noise ratio(SNR),lesion contrast and lesion contrast-to-noise ratio(CNR)were recorded and compared.Besides,overall image quality and insulinoma depiction were also compared.ANOVA and Friedman's test were performed.Results The image noise decreased and the SNR of pancreas increased with the increase in averaging time points(all P0.99)and were higher than that of the first group(all P<0.05).There was no significant difference in overall image quality among the 5 groups(P=0.977).Conclusions Image averaged from 5 scans showed moderate image noise,pancreas SNR and relatively high lesion contrast and lesion CNR.Therefore,it is advised to be used in image averaging to detect insulinoma.

ABSTRACT

Resumen La endosonografía es un método diagnóstico que viene revolucionando el abordaje de los pacientes con tumores del tracto gastrointestinal y de otros órganos y estructuras extradigestivas. En la actualidad, se viene posicionando como un método de elección en la evaluación de lesiones subepiteliales gastrointestinales y en la estadificación de muchos tumores gastrointestinales como de esófago, estómago, recto y páncreas. Por lo anterior pretendemos hacer una revisión de tema mostrando la evidencia de la endosonografía en indicaciones clásicas y aplicaciones actuales en tumores gastrointestinales.


Abstract Endosonography is a diagnostic method that has revolutionized the way to approach patients with tumors in the gastrointestinal tract and other extra-digestive organs and structures. Currently, it is a method of choice to assess subepithelial lesions of the gastrointestinal tract and to classify gastrointestinal tumors in the esophagus, stomach, rectum, and pancreas. Therefore, this literature review presents evidence on the classical indications of endosonography, as well as current applications to approach gastrointestinal tumors.

ABSTRACT

Introdução: a ultrassonografia tem sido utilizada na identificação da doença pancreática gordurosa não alcoólica (DPGNA), entretanto o método apresenta como desvantagem a subjetividade do examinador. Objetivo: quantificar a ecogenicidade pancreática para classificar em graus a DPGNA. Metodologia: utilizou-se a análise de histograma de escala de cinzas para quantificar a ecogenicidade, com a finalidade de análise mais acurada das características do tecido pancreático. Inicialmente, foi calculado o intervalo representativo da ecogenicidade pancreática e renal (média ± 2 desvios-padrão, que corresponde aos 97,5% mais representativos do tecido). Posteriormente, foi determinado o percentual de sobreposição da ecogenicidade do pâncreas com o rim analisado. Resultados: consideraram-se como normal quando o percentual de sobreposição de ecogenicidade estava em até 25%; esteatose grau I para percentual entre 25 e 50%; esteatose grau II para percentual entre 50 e 75%; esteatose grau III para percentual acima de 75%.Conclusão: os autores concluem que, com quantificação de ecogenicidade, a classificação de DPGNA torna-se não examinador-dependente.


Ultrasonography has been used in the identification of non-alcoholic fatty pancreatic disease (NAFPD) however the method presents the subjectivity of examiner as disadvantage. Objective: the aim of this study is to quantify pancreas echogenicity and classify NAFPD degrees. Methodology: to provide for an accurate analysis, a gray-scale histogram was used to quantify the liver parenchyma echogenicity. Initially, a calculation was made to find the representative interval of liver and underlying kidney echogenicity (average ± 2 standard deviations, which corresponds to the 97.5% of the most representative portion of the tissue). Afterwards, the percentage of overlapping echogenicity of kidney was determined. Results: results were considered normal when the percentage of overlapping echogenicity was up to 25%; mild steatosis (or degree 1), a percentage between 25% and 50%; moderate steatosis (degree 2), a percentage between 50% and 75%; and severe steatosis (degree 3), a percentage above 75%. Conclusion: the quantification and classification of pancreas echogenicity for NAFPD using a gray-scale histogram is objective and non-examiner dependent.

ABSTRACT

Resumen Presentamos el caso de una paciente que tenía un tumor del páncreas -denominado glucagonoma- y cuyo diagnóstico se sospechó por las manifestaciones cutáneas, las cuales nos condujeron realizar una tomografía axial computarizada (TAC). En ella se halló una masa. La paciente se remitió a cirugía y presentó una buena evolución.


Abstract This is a case report of a patient with a pancreatic tumor, known as glucagonoma, whose diagnosis was suspected because of skin manifestations which led to performing a CT scan, finding the mass. She underwent surgery with satisfactory results.
