Íleo biliar: descripción de dos casos / Gallstone ileus: Description of two cases

Introducción. El íleo biliar es una complicación rara de la colelitiasis y su incidencia varía del 1 al 4 %. Consiste en la migración de un cálculo de la vesicular biliar al tracto gastrointestinal, generando obstrucción intestinal. Presenta síntomas inespecíficos dependiendo del nivel de la obstrucción, lo que hace que su diagnóstico no suela ser precoz, repercutiendo en el deterioro clínico del paciente. Es especialmente grave en pacientes de edad avanzada y con comorbilidades. Casos clínicos. Se reportan los casos de dos pacientes con dolor abdominal difuso, en quienes se diagnosticó íleo biliar por tomografía. Se realizó manejo quirúrgico, el primero mediante técnica abierta y estrategia de dos pasos, y el otro mediante técnica laparoscópica. Discusión. El íleo biliar es una etiología rara de obstrucción intestinal. El cálculo migra debido a una fistula colecisto-entérica y el nivel de obstrucción es con mayor frecuencia la válvula ileocecal. Los síntomas son inespecíficos y dependen del nivel de obstrucción: dolor abdominal difuso mal caracterizado, náuseas, vómito, ausencia de flatos. El diagnóstico se hace mediante tomografía abdominal, en la cual se evidencia la tríada de Rigler. El manejo es quirúrgico, con enterotomía para extraer el cálculo y resolver la obstrucción. Conclusión. El íleo biliar es una patología que debe ser considerada en el abordaje de la obstrucción intestinal, aunque sea poco frecuente. El manejo quirúrgico es clave para resolver el cuadro de obstrucción intestinal; aún así genera importante morbimortalidad en especial en pacientes de avanzada edad.

Introduction. Gallstone ileus is a rare complication of cholelithiasis, its incidence varies from 1% to 4%. It consists of the migration of a stone from the gallbladder to the gastrointestinal tract, causing intestinal obstruction. It presents with non-specific symptoms depending on the level of the obstruction, which means that its diagnosis is not usually early, with repercussions on the clinical deterioration of the patient, being serious especially in elderly patients and with comorbidities. Clinical cases. Two patients with diffuse abdominal pain are reported. A tomographic diagnosis was made showing gallstone ileus. Surgeries were performed, in the first case using an open technique and a 2-step strategy, and on the second one using a laparoscopic technique. Discussion. Gallstone ileus is a rare etiology of intestinal obstruction. Symptoms are usually poorly characterized: diffuse abdominal pain, nausea, vomiting, absence of flatus. The diagnosis is made by abdominal tomography in which Rigler's triad is evident. Management is surgical through enterotomy to remove the stone and resolve the obstruction. Conclusion. Gallstone ileus is a rare pathology that should be considered in the approach to intestinal obstruction. Surgical management is key to resolving intestinal obstruction. Even so, it generates significant morbidity and mortality, especially in elderly patients.

Hotspots and difficulties of biliary surgery in older patients / 中华医学杂志(英文版)

With the accelerated aging society in China, the incidence of biliary surgical diseases in the elderly has increased significantly. The clinical characteristics of these patients indicate that improving treatment outcomes and realizing healthy aging are worthy of attention. How to effectively improve the treatment effect of geriatric biliary surgical diseases has attracted widespread attention. This paper reviews and comments on the hotspots and difficulties of biliary surgery in older patients from six aspects: (1) higher morbidity associated with an aging society, (2) prevention and control of pre-operative risks, (3) extending the indications of laparoscopic surgery, (4) urgent standardization of minimally invasive surgery, (5) precise technological progress in hepatobiliary surgery, and (6) guarantee of peri-operative safety. It is of great significance to fully understand the focus of controversy, actively make use of its favorable factors, and effectively avoid its unfavorable factors, for further improving the therapeutic effects of geriatric biliary surgical diseases, and thus benefits the vast older patients with biliary surgical diseases. Accordingly, a historical record with the highest age of 93 years for laparoscopic transcystic common bile duct exploration has been created by us recently.

Risco pré-operatório de coledocolitíase em colecistectomiasem um hospital terciário de João Pessoa-PB / Preoperative risk of common bile duct stones in cholecystectomies at a tertiary hospital in João Pessoa-PB

Introdução: a colelitíase é uma das doenças mais comuns do trato digestivo, acometendo 6-10% da população adulta. Destes, aproximadamente 8- 20% apresentam coledocolitíase associada. A estratificação de risco de coledocolitíase pré-operatória nos portadores de colelitíase busca subsidiar a definição de uma terapêutica mais adequada, em tempo hábil, para cada caso. Objetivo:estratificar o risco pré-operatório de coledocolitíase em pacientes submetidos a colecistectomia em um hospital terciário. Metodologia:estudo observacional descritivo, retrospectivo, a partir da análise de prontuários de pacientes submetidos a colecistectomia por cálculos biliares em um hospital público em João Pessoa, Paraíba, entre agosto de 2021 e janeiro de 2022, durante a pandemia de COVID-19. A estratificação de risco foi realizada a partir do estabelecido pela Sociedade Americana de Endoscopia Digestiva (ASGE) em 2010. Resultados: foram selecionados 41 pacientes, a maior parte do sexo feminino, com média de idade de 49,6 anos, em sua maioria submetidos a colecistectomia videolaparoscópica, sem colangiografia intraoperatória. O exame de imagem mais realizado no pré-operatório foi a ultrassonografia de abdome. De acordo com os critérios da ASGE, 18 (43,9%) pacientes foram classificados como baixo risco, 19 (46,4%) foram estratificados no risco intermediário, e 4 foram de alto risco (9,7%). Conclusão: apesar de uma amostra de tamanho limitado, evidencia-se frequência relevante do risco alto ou intermediário de coledocolitíase em portadores de colelitíase. A estratificação de risco para coledocolitíase é uma ferramenta importante a ser utilizada de rotina no pré-operatório da colecistectomia nos pacientes com diagnóstico de colelitíase.

Introduction: gallstones are one of the most common diseases of the digestive tract, affecting 6-10% of the adult population. Of these, approximately 8-20% have associated choledocholithiasis. Preoperative risk stratification of choledocholithiasis in patients with cholelithiasis seeks to allow setting of a proper therapy, in a timely manner, for each case. Objective: stratify preoperative risk of choledocholithiasis in patients undergoing cholecystectomy in a tertiary hospital. Methods: descriptive, retrospective observational study, based on the analysis of medical records of patients undergoing cholecystectomy for gallstones in a public hospital in João Pessoa, Paraíba, between August 2021 and January 2022, during COVID-19 pandemic. Risk stratification was performed based on American Society for Digestive Endoscopy (ASGE) criteria from 2010. Results: 41 patients were evaluated. Most of them were female, with a mean age of 49.6 years, most of whom underwent laparoscopic cholecystectomy without intraoperative cholangiography. The most common imaging performed preoperatively was abdominal ultrasound. According to ASGE criteria, 18 (43.9%) patients were classified as low risk, 19 (46.4%) were stratified into intermediate risk, and 4 scored high risk (9.7%). Conclusion: despite a limited sample size, there is a relevant prevalence of high or intermediate preoperative risk of choledocholithiasis in patients with cholelithiasis. Risk stratification for choledocholithiasis is an important tool to be routinely used in the preoperative period of cholecystectomy in patients with diagnosis of cholelithiasis.

Síndrome de Bouveret como variante de íleo biliar / Bouveret syndrome as a variant of gallstone ileus

Introducción. El síndrome de Bouveret es una variante del íleo biliar, de rara presentación dentro de las causas de obstrucción intestinal, generada por la impactación de un lito biliar a nivel del duodeno, secundario a la formación de una fístula bilioentérica. Es más común en mujeres en la octava década de la vida, con múltiples comorbilidades. y presenta síntomas inespecíficos, documentándose la triada de Rigler hasta en el 80 % de las tomografías de abdomen. La cirugía sigue siendo el tratamiento de elección. Caso clínico. Presentamos el caso de una paciente de 76 años, con múltiples antecedentes y cuadros previos de cólico biliar, que consultó por dolor abdominal y signos de hemorragia de vías digestivas altas y se documentó un síndrome de Bouveret. Fue tratada en la misma hospitalización mediante extracción quirúrgica del cálculo con posterior resolución de su sintomatología.Conclusión. A pesar de que el síndrome deBouveret es una entidad de infrecuente presentación, los cirujanos generalesdeben estar familiarizados con esta patología, en el contexto del paciente que consulta con un cuadro de obstrucción intestinal, conociendo el valor de la tomografía de abdomen y la endoscopia de vías digestivas altas, teniendo en cuenta la edad y las condiciones del paciente para definir el manejo quirúrgico más adecuado.

Introduction. Bouveret's syndrome is a variant of gallstone ileus, of rare presentation within the causes of intestinal obstruction, generated by the impaction of a biliary stone at the level of the duodenum, secondary to the formation of a biliary-enteric fistula. It is more common in women in the eighth decade of life, with multiple comorbidities, and presents non-specific symptoms, with Rigler's triad being documented in up to 80% of abdominal CT scans. Surgery remains the treatment of choice. Clinical case. We present the case of a 76-year-old patient, with history of multiple episodes of biliary colic, who consulted for abdominal pain and signs of upper gastrointestinal bleeding. Bouveret's syndrome was documented. She was treated in the same hospitalization by surgical extraction of the stone with subsequent resolution of her symptoms. Conclussion. Although Bouveret's syndrome is an entity of infrequent presentation, general surgeons must be familiar with this pathology in the context of the patient who presents with intestinal obstruction, knowing the value of abdominal tomography and upper GI endoscopy, taking into account the age and conditions of the patient to define the most appropriate surgical management.

Terapia de presión negativa para el manejo de abdomen catastrófico secundario a íleo biliar / Negative Pressure Therapy for Managing Catastrophic Abdomen following Gallstone Ileus

Introducción: El abdomen catastrófico o abdomen hostil es una entidad quirúrgica de gran importancia por la pérdida de los distintos espacios entre los órganos de la cavidad abdominal y las estructuras de la cavidad abdominal. Estas alteraciones producen cambios anatómicos grandes por un síndrome adherencial severo. Objetivo: Demostrar la presentación de un abdomen catastrófico posterior a manejo de íleo biliar en un paciente adulto. Caso clínico: Paciente masculino de 43 años que producto de un abdomen agudo obstructivo por íleo biliar evolucionó tórpidamente en otra casa asistencial. Se realizaron 3 intervenciones quirúrgicas, hasta llegar a nuestra casa asistencial donde se le trata de manera multidisciplinaria e integral. Estuvo 120 días hospitalizado y se le realizó 5 intervenciones quirúrgicas para aplicación y recambio de terapia de presión negativa abdominal abierta (ABThera). Durante la última intervención al encontrar una cavidad limpia y sin fugas se realiza gastroentero anastomosis en Y de Roux con una buena evolución clínico-quirúrgica hasta el alta, con seguimiento dos meses posteriores por consulta externa. Conclusiones: El abdomen catastrófico es un reto para el manejo por los cirujanos porque se requiere aparte de un vasto conocimiento también el apoyo de otras especialidades para poder combatir esta entidad(AU)

Introduction: Catastrophic abdomen or hostile abdomen is a surgical entity of great significance due to the loss of the different spaces between organs and the structures of the abdominal cavity. These alterations produce major anatomical changes due to a severe adhesive syndrome. Objective: To show the presentation of a catastrophic abdomen following gallstone ileus management in an adult patient. Clinical case: A 43-year-old male patient who, as a consequence of an acute obstructive abdomen due to gallstone ileus, had a torpid evolution into another care facility. Three surgical interventions were performed before he arrived at our care facility, where he was treated in a multidisciplinary and comprehensive way. He was hospitalized for 120 days and underwent five surgical interventions for application and replacement of the open abdomen negative pressure therapy (ABThera). During the last intervention, upon finding a clean cavity without leaks, a Roux-en-Y gastroenteric anastomosis was performed, with a good clinical-surgical evolution until discharge and follow-up of two months thereafter in the outpatient clinic. Conclusions: Catastrophic abdomen is a challenge to be managed by surgeons because it requires, apart from vast knowledge, the support of other specialties to combat this entity(AU)

Estudio complementario de la patología biliar complicada y el manejo de la litiasis coledociana en dos tiempos / Complementary evaluation of complicated gallstone disease and two-stage management of choledochal lithiasis

RESUMEN Antecedentes: la litiasis biliar tiene una prevalencia actual en Occidente del 10-20%. El 7-16% de los pacientes presentan también coledocolitiasis. El diagnóstico preoperatorio de coledocolitiasis es difícil de establecer. Objetivo: establecer nuestra experiencia en el estudio de la patología biliar complicada y el manejo de la coledocolitiasis en dos tiempos, como terapéutica de elección. Material y métodos: estudio prospectivo, observacional. Pacientes con patología biliar sometidos a procedimientos en el Servicio de Cirugía General del Hospital Vidal, desde el 30/06/2019 al 30/12/2019. Resultados: la ecografía hepato-bilio-pancreática (HPB) es específica, con exactitud del 80,9% y sensibilidad del 50%. La colangio resonancia magnética (CRNM) es 100% específica, tiene exactitud del 84,6% y sensibilidad de 67%. La colangio pancreatografía retrógrada endoscópica (ERCP -por sus siglas en inglés-), durante la primera colangiografía mostró en el 100% litiasis coledociana, pero, luego del tratamiento, la colangiografía de "control" muestra 0% de sensibilidad, 100% especificidad, con exactitud del 15,4%. En los hallazgos intraoperatorios, el cístico dilatado en asociación con alteraciones humorales ha demostrado una sensibilidad del 100%, especificidad del 90% y tasa de exactitud de 93,6%. Conclusión: la colangiografía intraoperatoria (CIO) es el procedimiento de referencia ("gold standard") en el abordaje de la patología biliar complicada, siendo su uso sistemático. La asociación entre alteraciones de parámetros humorales y el cístico dilatado resulta un parámetro con alto valor predictivo para la presencia de litiasis coledociana.

ABSTRACT Background: Nowadays, the prevalence of gallstones ranges between 10 and 20% in Western world, and 7-16% of the patients also present choledocholithiasis. The preoperative diagnosis of choledocholithiasis is difficult. Objective: To establish our experience in the evaluation of complicated gallstone disease and two-stage management of choledochal lithiasis as standard or care. Material and methods: This prospective and observational study included patients hospitalized with gallstone disease undergoing procedures in the Department of General Surgery of Hospital Vidal from June 30, 2019, to December 30, 2019. Results: Ultrasound of the liver, biliary tract and pancreas was specific, with accuracy of 80.9% and sensitivity of 50%. Magnetic resonance cholangiopancreatography (MRCP) had a sensitivity of 100%, accuracy of 84.6% and sensitivity of 67%. As for endoscopic retrograde cholangiopancreatography (ERCP), the diagnosis of choledocholithiasis was made in 100% of the cases during the first cholangiography while "control" cholangiography had a sensitivity of 0%, specificity of 100% and accuracy of 15.4%. The presence of a dilated cystic duct intraoperatively in association with abnormal biochemical parameters had a sensitivity of 100%, specificity of 90%, and accuracy of 93.6%. Conclusion: Intraoperative cholangiography (IOC) is the gold standard procedure for the management of complicated gallstone disease. The association of biochemical parameters and a dilated cystic duct has high predictive value for choledochal lithiasis.

Ultrasonido endoscópico (USE) y colangio-pancreatografía endoscópica retrógrada (CPRE) sin fluoroscopia en el tratamiento de la coledocolitiasis durante el embarazo: reporte de 2 casos / Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) without fluoroscopy for the treatment of choledocholithiasis during pregnancy: Report of 2 cases

Resumen La enfermedad litiásica biliar es una patología frecuente en mujeres embarazadas, y las complicaciones relacionadas con los cálculos biliares durante el embarazo pueden generar desenlaces adversos tanto en la madre como en el feto. La coledocolitiasis en el embarazo requiere de una aproximación diagnóstica adecuada y su manejo busca minimizar los riesgos de las intervenciones médicas. Se describen dos casos de mujeres embarazadas quienes presentan coledocolitiasis documentada por colangiorresonancia. Se realizó el tratamiento con la combinación de ultrasonido endoscópico (USE) y colangiopancreatografía endoscópica retrógrada (CPRE) sin fluoroscopia, con lo cual se logró resolver la coledocolitiasis sin exponer al feto a radiación ionizante, se confirmó la permeabilización del colédoco y se observó una adecuada evolución posoperatoria tanto materna como fetal.

Abstract Biliary lithiasis is a common condition in pregnant women, and complications related to gallstones during pregnancy can lead to adverse outcomes in both the mother and the fetus. Choledocholithiasis during pregnancy requires an adequate diagnostic approach to minimize the risks of medical interventions. The following are two cases of pregnant women with choledocholithiasis diagnosed using magnetic resonance cholangiography. Treatment included a combination of endoscopic ultrasound and retrograde endoscopic cholangiopancreatography (ERCP) without fluoroscopy, achieving the resolution of choledocholithiasis, without exposing the fetus to ionizing radiation, confirming the permeabilization of the common bile duct, and observing an adequate postoperative evolution of both the mother and the fetus.

Predictores de Coledocolitiasis en pacientes con litiasis vesicular sintomática tratados en la Segunda Cátedra de Clínica Quirúrgica, Hospital de Clínicas, San Lorenzo año 2017-2019 / Predictors of Choledocholithiasis in patients with symptomatic gallstones treated in the II General Surgery Service of Clinica´s Hospital, San Lorenzo, year 2017-2019

La litiasis vesicular sintomática puede presentarse asociada a litiasis de la vía biliar principal, siendo necesaria la utilización de medios diagnósticos adecuados para su posterior tratamiento. En este trabajo, se sugiere la evaluación mediante las guías de la Sociedad Americana para Endoscopia Gastrointestinal (American Society for Gastrointestinal Endoscopy ASGE), usando factores como la edad, pruebas hepáticas y hallazgos ecográficos, categorizando a los pacientes en baja, intermedia y alta probabilidad de coledocolitiasis. Estudio de diseño retrospectivo, observacional, descriptivo, de corte transversal, con un muestreo no probabilístico de casos consecutivos, sobre pacientes con diagnóstico de litiasis vesicular sintomática y sospecha de litiasis de la via biliar principal internados en la II Cátedra de Clínica Quirúrgica, del Hospital de Clínicas de San Lorenzo, entre los años 2017 a 2019. Con los siguientes resultados, de un total de 339 pacientes con diagnóstico de litiasis vesicular sintomática, el 6,64% tuvo el diagnóstico de coledocolitiasis asociada. En cuanto a los predictores muy fuertes de coledocolitiasis el más frecuentemente (68,6%,) encontrado fue el nivel de la bilirrubina total ≥ 4mg/dl; de los predictores fuertes el 70,6% presentaba la vía biliar principal dilatada; de los predictores moderados, el 84,3% presentó las enzimas hepáticas alteradas. En conclusión, se pudo identificar que la mayoría de los pacientes presentó alta probabilidad de coledocolitiasis y la conducta tomada fue realizar en primer lugar una colangiografía retrógrada endoscópica, con fines terapéuticos y luego colecistectomía, correspondiente al manejo correcto establecido por las guías actuales internacionales.

Symptomatic gallstones can occur associated with lithiasis of the main bile duct, requiring the use of adequate diagnostic tools for subsequent treatment. In this paper, we suggest using the guidelines of the American Society for Gastrointestinal Endoscopy (ASGE), that uses factors such as age, liver tests, and ultrasound findings, categorizing patients as those with low, intermediate, and high probability. of choledocholithiasis. A Retrospective, observational, descriptive, cross-sectional design study, with a non-probabilistic sampling of consecutive cases, on patients with a diagnosis of symptomatic gallstones and suspected stones of the main bile duct admitted to the the 2nd Surgical Department and Service of Clinica´s Hospital of San Lorenzo, between the years 2017 to 2019. With the following results; of a total of 339 patients with the diagnosis of symptomatic gallstones, 6.64% had associated choledocholithiasis. Regarding the very strong predictors of choledocholithiasis, the most frequent (68.6%) was the total bilirubin level ≥ 4mg / dl; 70.6% had a dilated main bile duct as a strong predictor; as a moderate predictor, 84.3% had altered liver enzymes. In conclusion, it was possible to identify that most of the patients presented a high probability of choledocholithiasis and the action taken was to first perform an endoscopic retrograde cholangiography, for therapeutic purposes, and then cholecystectomy, corresponding to the correct management established by current international guidelines.

Reporte de Caso Clínico: Migración de cálculo dificultoso / Case Report: Migration of Large Gallstone

INTRODUCCIÓN: La coledocolitiasis es una patología con alta tasa de migración al duodeno de cálculos pequeños. No obstante, la migración asintomática de cálculos mayores a 1 cm (macrolitiasis) es atípica. A continuación, presentamos un caso de migración de un macrocálculo ubicado en colédoco medio. CASO CLÍNICO: Presentamos el caso de un hombre de 27 años que consulta por epigastralgia postprandial de 4 meses de evolución. La ecografía abdominal mostró barro biliar y un macro-cálculo en colédoco, con Colangio-RM se confirmó diagnóstico. Se decidió realizar una colecistectomía laparoscópica, con colangiografía intraoperatoria (CIO). EVOLUCIÓN: Durante la colecistectomía laparoscópica, no se evidenció cálculos en la colangiografía intraoperatoria, ante la discordancia entre las imágenes preoperatorias la CIO, se realizó instrumentación transcística con canastilla de Dormia, sin extracción de cálculos. El paciente evolucionó favorablemente, sin complicaciones dadas por la migración del macro-cálculo. Se realizó CRM posquirúrgica, sin evidencia de imágenes endoluminales en la vía biliar. CONCLUSIÓN: La patología biliar es dinámica, pudiendo presentar migración litiásica, aún en macro cálculos o cálculos de difícil manejo. Si bien la ecografÍa y la CRM tienen alta sensibilidad para su diagnóstico; la CIO es fundamental para hacer diagnóstico y tratamiento de la patología litiásica resolviéndola en un solo tiempo operatorio evitando procedimientos múltiples.(au)

BACKGROUND: Common bile duct lithiasis is a pathology with a high rate of migration of small stones to the duodenum. However, asymptomatic migration of stones larger than 1cm (macrolithiasis) is atypical. We present a case of migration of a macrocalculus located in the middle of the common bile duct. CASE REPORTS: We present the case of a 27-years-old man, who consulted for postprandial epigastric pain, that started 4 months ago. Abdominal ultrasound showed biliary sludge and common bile duct macrocalculus, with Cholangio-MRI the diagnosis was confirmed. A laparoscopic cholecystectomy with intraoperative cholangiography was performed. EVOLUTION: During the laparoscopic cholecystectomy, no stones were evidenced in the intraoperative cholangiograpy. Due to the disagreement between the preoperative IOC images, transcystic instrumentation with a Dormia basket was performed, without stone extraction. The patient had a favorably evolution, without complications due to the stone migration. Postoperative MRC was performed, without evidence of endoluminal images in the bile duct. CONCLUSIONS: Biliary pathology is dynamic, with the possibility of gallstone migration, even for large gallstones and complicated cases. Although ultrasound and MRI have high sensitivy for diagnosis; IOC is essential to diagnose and treat lithiasic pathology, resolving it in a single operating time, avoiding multiple procedures.

Obstrucción intestinal por íleo biliar. Presentación de caso / Intestinal obstruction due to gallstone ileus. A case report

El íleo biliar es una causa infrecuente de obstrucción intestinal mecánica que afecta a los adultos mayores, predominantemente a las mujeres. En la mayoría de los casos es causada por la impactación de un cálculo biliar en el intestino a través de una fístula bilioentérica y clínicamente se caracteriza por dolor abdominal y emesis aguda o subaguda. Se requiere una evaluación con imágenes abdominales para confirmar el diagnóstico, determinar la ubicación del cálculo ectópico y el tamaño del mismo. Entre las modalidades de imagen disponibles, la tomografía de abdomen es el estándar de oro; sin embargo, cuando no está disponible se puede utilizar una radiografía de abdomen simple. Su manejo es principalmente quirúrgico. Este caso es de importancia por la rareza de su presentación al ser en un hombre, con un cálculo relativamente pequeño; adicionalmente, por la relevancia que tienen las imágenes de abdomen en el diagnóstico de esta patología.

Gallstone ileus is an infrequent cause of mechanical intestinal obstruction that affects older adults, predominantly women. In most cases it is caused by the impaction of a gallstone into the bowel through a bilioenteric fistula and is clinically characterized by abdominal pain and acute or subacute emesis. Evaluation with abdominal imaging is required to confirm the diagnosis, determine the location of the ectopic stone and its size. Among the imaging modalities available, abdominal tomography is the gold standard; however, when it is not available, a simple abdominal radiograph can be used. Management is mainly surgical. This case is of importance given the rarity of its presentation being in a man, with a relatively small calculus; additionally, because of the relevance of abdominal imaging in the diagnosis of this pathology.

Síndrome de bouveret, una forma infrecuente de íleo biliar: a propósito de un caso y revisión de la literatura / Bouveret syndrome, a rare presentation of biliary ileus: case report and literature review

El íleo biliar es una complicación poco frecuente de la colelitiasis o colecistitis litiásica, aparece en menos del 1-3% de los pacientes con estas enfermedades, se define como una obstrucción intestinal mecánica debido a la impactación de uno o más cálculos biliares dentro del tracto gastrointestinal. Ubicaciones menos comunes incluyen estómago y duodeno (síndrome de Bouveret) y el colon. El diagnóstico del síndrome de Bouveret (SB) suele iniciar con una radiografía simple de abdomen; la ecografía abdominal confirma el síndrome de Bouveret si revela neumobilia y ubicación ectópica del cálculo biliar, sin embargo, en la mayoría de los casos se necesita una tomografía computarizada que permite una evaluación completa.Caso Clínico : Se presenta caso de masculino de 57 años de edad quien 8 días previo a su ingreso presenta dolor abdominal en epigastrio de moderada intensidad acompañado de pirosis, halitosis, náuseas, vómitos, intolerancia a la vía oral y ausencia de evacuaciones; acude inicialmente a gastroenterólogo que realiza endoscopia digestiva superior encontrando una imagen de obstrucción a nivel de primera porción de duodeno, motivo por el cual refiere a servicio de cirugía general donde es intervenido quirúrgicamente, se diagnostica el SB realizando gastrotomía, extracción del lito y piloroplastia, presentando adecuada evolución postoperatoria.Conclusión : El SB es un diagnóstico raro que afecta a <0,5% de los pacientes con cálculos biliares por lo que requiere un grado extremadamente alto de sospecha para el diagnóstico y puede observarse de manera incidental en estudios de imágenes en pacientes que presentan síntomas de obstrucción del vaciamiento gástrico(AU)

Biliary ileus is a rare complication of cholelithiasis or lithiasic cholecystitis, appearing in less than 1 to 3% of patients with these diseases, it is a mechanical intestinal obstruction due to the impaction of one or more gallstones within the gastrointestinal tract. Less common locations include the stomach and duodenum (Bouveret syndrome) and the colon. For the diagnosis of Bouveret's syndrome (BS) the initial step is usually a simple abdominal X-ray, while an abdominal ultrasound confirms Bouveret's syndrome if it reveals pneumobilia and ectopic location of the gallstone, in most cases a computed tomography (CT) scan is needed for diagnosis and full evaluation.Clinical Case: We present the clinical case of a 57-year-old male who 8 days prior to his admission presented with moderate intensity abdominal pain in the epigastrium accompanied by heartburn, halitosis, nausea, vomiting, intolerance to oral intake, and absence of evacuations; initially went to a gastroenterologist who performed upper digestive endoscopy, finding an image of obstruction at the level of the first portion of the duodenum, which is why he refers to the general surgery department where he underwent surgery, diagnosing BS by performing gastrotomy, stone extraction, and pyloroplasty, presenting adequate postoperative evolution.Conclusion : BS is a rare diagnosis that affects <0.5% of patients with gallstones and therefore requires an extremely high degree of suspicion for the diagnosis and can be seen incidentally on imaging studies in patients with symptoms of obstruction of gastric emptying(AU)

Role of osteopontin in diet-induced brown gallstone formation in rats / 中华医学杂志(英文版)

BACKGROUND@#Although osteopontin (OPN) is expressed in the liver and pigment gallstones of patients with hepatolithiasis, its role in pigment gallstone formation remains unclear. This study aimed to explore the function of OPN in pigment gallstone formation.@*METHODS@#Rats were fed a chow diet (CD) or lithogenic diet (LD) for 10 consecutive weeks; blocking tests were then performed using an OPN antibody (OPN-Ab). Incidence of gallstones and levels of several bile components, OPN, tumor necrosis factor alpha (TNF-α), and cholesterol 7 alpha-hydroxylase (CYP7A1) were analyzed. To determine TNF-α expression in hepatic macrophages and both CYP7A1 and bile acid (BA) expression in liver cells, recombinant rat OPN and recombinant rat TNF-α were used to treat rat hepatic macrophages and rat liver cells, respectively. Chi-square or Fisher exact tests were used to analyze qualitative data, Student t-test or one-way analysis of variance were used to analyze qualitative data.@*RESULTS@#Incidence of gallstones was higher in LD-fed rats than in CD-fed rats (80% vs. 10%, P < 0.05). BA content significantly decreased in bile (t = -36.08, P < 0.01) and liver tissue (t = -16.16, P < 0.01) of LD-fed rats. Both hepatic OPN protein expression (t = 9.78, P < 0.01) and TNF-α level (t = 8.83, P < 0.01) distinctly increased in the LD group; what's more, CYP7A1 mRNA and protein levels (t = -12.35, P < 0.01) were markedly down-regulated in the LD group. Following OPN-Ab pretreatment, gallstone formation decreased (85% vs. 25%, χ2 = 14.55, P < 0.01), liver TNF-α expression (F = 20.36, P < 0.01) was down-regulated in the LD group, and CYP7A1 expression (F = 17.51, P < 0.01) was up-regulated. Through CD44 and integrin receptors, OPN promoted TNF-α production in macrophage (F = 1041, P < 0.01), which suppressed CYP7A1 expression (F = 48.08, P < 0.01) and reduced liver BA synthesis (F = 119.4, P < 0.01).@*CONCLUSIONS@#We provide novel evidence of OPN involvement in pigmented gallstone pathogenesis in rats.
