Duplicación del colédoco asociado a unión biliopancreática anómala: Reporte de caso / Common bile duct duplication associated with anomalous biliopancreatic junction: A case report

Introducción. La duplicación del colédoco es una anomalía congénita poco frecuente. En la mayoría de los casos este defecto se asocia a cálculos en la vía biliar, unión pancreatobiliar anómala, pancreatitis, cáncer gástrico o colangiocarcinoma. Por esta razón, el diagnóstico y el tratamiento temprano son importantes para evitar las complicaciones descritas a futuro. Métodos. Se presenta el caso de una paciente de 30 años, con antecedente de pancreatitis aguda, con cuadro de dolor abdominal crónico, a quien se le realizaron varios estudios imagenológicos sin claro diagnóstico. Fue llevada a manejo quirúrgico en donde se documentó duplicación del colédoco tipo II con unión pancreatobiliar anómala. Resultados. Se hizo reconstrucción de las vías biliares y hepatico-yeyunostomía, con adecuada evolución postoperatoria y reporte final de patología sin evidencia de tumor. Conclusión. El diagnóstico se hace mediante ecografía endoscópica biliopancreática, colangiorresonancia o colangiopancreatografía retrógrada endoscópica. El tratamiento depende de si está asociado o no a la presencia de unión biliopancreática anómala o cáncer. Si el paciente no presenta patología neoplásica, el tratamiento quirúrgico recomendado es la resección del conducto con reconstrucción de las vías biliares.

Introduction. Double common bile duct is an extremely rare congenital anomaly. This anomaly may be associated with bile duct stones, anomalous biliopancreatic junction, pancreatitis, bile duct cancer, or gastric cancers. Thus, early diagnosis and treatment is important to avoid complications. Clinical case. We report a rare case of double common bile duct associated with an anomalous biliopancreatic junction in a 30-year-old female, with prior history of acute pancreatitis, who presented with chronic abdominal pain. She underwent several imaging studies, without clear diagnosis. She was taken to surgical management where duplication of the type II common bile duct was documented with anomalous pancreatobiliary junction. Results. Reconstruction of the bile ducts and hepatico-jejunostomy were performed, with adequate postoperative evolution and final pathology report without evidence of tumor. Conclusion. Diagnosis is usually performed by an endoscopic ultrasound, magnetic resonance cholangiopancrea-tography, or endoscopic retrograde cholangiopancreatography. Treatment depends on the presence of anomalus biliopancreatic junction or concomitant cancer. In cases without associated malignancy, resection of bile duct and biliary reconstruction is the recommended surgical treatment.

Prognostic role of magnetic resonance imaging of the abdomen with intravenous contrast and magnetic resonance cholangiopancreatography in primary sclerosing cholangitis / Papel prognóstico da ressonância magnética do abdome com contraste intravenoso e colangiopancreatografia por ressonância magnética na colangite esclerosante primária

Abstract Objective: To evaluate the usefulness of Anali scores, determined by magnetic resonance imaging, for predicting the prognosis of primary sclerosing cholangitis (PSC) and to analyze interobserver variability, as well as to assess the impact of periportal edema and heterogeneous signal intensity on diffusion-weighted imaging of the liver. Materials and Methods: This was a retrospective cohort study of 29 patients with PSC and baseline magnetic resonance imaging. Anali scores, without gadolinium (0-5 points) and with gadolinium (0-2 points), were calculated by two radiologists. Clinical end-points included liver transplantation, cirrhotic decompensation, and death. We calculated intraclass correlation coefficients (ICCs) for interobserver agreement on the Anali scores, performed Kaplan-Meier survival analysis comparing event-free survival among the score strata, and calculated the areas under receiver operating characteristic curves to determine sensitivity and specificity. Results: Among the patients with a clinical event, the median Anali score was 4 (interquartile range [IQR], 2-5) without gadolinium and 2 (IQR, 1-2) with gadolinium, compared with 1 (IQR, 1.0-2.5) and 1 (IQR, 0.25-1.0), respectively, among those without a clinical event. The ICC was 0.79 (95% confidence interval: 0.57-0.91) for the Anali score with gadolinium and 0.99 (95% confidence interval: 0.98-0.99) for the Anali score without gadolinium. Periportal edema and heterogeneous signal intensity in the liver on diffusion-weighted imaging showed no statistical impact on clinical events (p = 0.65 and p = 0.5, respectively). Conclusion: Anali scores correlate with clinical events in PSC, with a high level of interobserver agreement.

Resumo Objetivo: Avaliar a utilidade dos escores Anali determinados por ressonância magnética para prever o prognóstico da colangite esclerosante primária (CEP), analisar a variabilidade interobservador e avaliar o impacto do edema periportal e do sinal heterogêneo do fígado em imagens ponderadas por difusão. Materiais e Métodos: Estudo retrospectivo de coorte de 29 pacientes com CEP e ressonância magnética de base. Os escores Anali sem gadolínio (0 a 5 pontos) e com gadolínio (0 a 2 pontos) foram calculados por dois radiologistas. Os desfechos clínicos incluíram transplante de fígado, descompensação cirrótica ou morte. Foram realizados coeficiente de correlação intraclasse (CCI) para a concordância interobservador com relação ao escore Anali, análise de sobrevivência de Kaplan-Meier comparando o tempo livre de eventos de acordo com o escore, e área sob a curva característica de operação do receptor para sensibilidade e especificidade. Resultados: Nos pacientes com evento clínico, a mediana do escore Anali sem gadolínio foi 4 (intervalo interquartil [IIQ]: 2-5) e com gadolínio foi 2 (IIQ: 1-2), enquanto nos pacientes sem evento clínico o escore sem gadolínio foi 1 (IIQ:1-2,5) e com gadolínio foi 1 (IIQ: 0,25-1). A concordância interobservador com gadolínio foi CCI = 0,79 (intervalo de confiança 95%: 0,57-0,91) e sem gadolínio foi CCI = 0,99 (intervalo de confiança 95%: 0,98-0,99). O edema periportal (p = 0,65) e o sinal heterogêneo do fígado nas imagens ponderadas por difusão (p = 0,5) não apresentaram impacto nos eventos clínicos. Conclusão: Os escores Anali se correlacionam com eventos clínicos na CEP, com alto grau de concordância interobservador.

Colangiografía videolaparoscópica intraoperatoria y colangiopancreatografía retrógrada endoscópica en pacientes con sospecha de colédocolitiasis / Intraoperative Videolaparoscopic Cholangiography and Endoscopic Retrograde Cholangiopancreatography in Patients with Suspected Choledocholithiasis

Introducción: La coledocolitiasis se ha convertido en un problema de salud para el cual existen disímiles opciones de tratamiento. Objetivo: Exponer los resultados obtenidos con la colangiografía videolaparoscópica intraoperatoria y la colangiopancreatografía retrógrada endoscópica en pacientes con sospecha de coledocolitiasis. Métodos: Se realizó un estudio descriptivo retrospectivo en pacientes con sospecha de coledocolitiasis sometidos a colangiografía videolaparoscópica y la colangiopancreatografía endoscópica en el Hospital Militar Clínico Quirúrgico Docente de Camagüey Dr. Octavio de la Concepción y de la Pedraja durante el período de enero de 2015 a diciembre de 2019. El universo lo conformaron los 117 pacientes sometidos a ambos procederes. Se controlaron las variables de sospecha de coledocolitiasis, grupos de edades, sexo, hallazgos imagenológicos, complicaciones e índice de sospecha de coledocolitiasis. Resultados: En la colangiografía videolaparoscópica intraoperatoria fue mayor la posibilidad diagnóstica y menor las complicaciones. El diagnóstico de coledocolitiasis fue mayor en los pacientes sometidos a colangiopancreatografía retrógrada endoscópica, aunque esta no permitió evaluar a pacientes con bajo riesgo. Los pacientes del sexo femenino fueron más frecuentes en ambos grupos y la sospecha de coledocolitiasis se observó en grupo de edades entre 31 y 45 años. Sin embargo, fue normal el hallazgo de las vías biliares en ambos procederes. Conclusiones: Ambos métodos son seguros y útiles en el estudio en pacientes con sospecha de coledocolitiasis, con mayor eficacia diagnóstica para la técnica videolaparoscópica y menos complicaciones. El hallazgo normal de la vía biliar fue el resultado que prevaleció en ambos procederes(AU)

Introduction: Choledocholithiasis has become a health problem for which there are dissimilar treatment options. Objective: To present the results obtained with intraoperative videolaparoscopic cholangiography and endoscopic retrograde cholangiopancreatography in patients with suspected choledocholithiasis. Methods: A retrospective and descriptive study was conducted in patients with suspected choledocholithiasis and submitted to videolaparoscopic cholangiography and endoscopic cholangiopancreatography at Hospital Militar Clínico Quirúrgico Docente Dr. Octavio de la Concepción y de la Pedraja, of Camagüey, during the period from January 2015 to December 2019. The study universe consisted of 117 patients submitted to both procedures. The variables of suspected choledocholithiasis, age groups, sex, imaging findings, complications and index of suspected choledocholithiasis were controlled. Results: Intraoperative videolaparoscopic cholangiography had a higher diagnostic possibility and lower complications. The diagnosis of choledocholithiasis was higher in patients submitted to endoscopic retrograde cholangiopancreatography, although this did not allow the assessment of low-risk patients. Female patients were more frequent in both groups, while suspected choledocholithiasis was observed in patients between 31 and 45 years of age. However, the finding of a normal biliary tract was common to both procedures. Conclusions: Both methods are safe and useful in the study in patients with suspected choledocholithiasis, with greater diagnostic efficacy, as well as fewer complications, for the videolaparoscopic technique. The finding of a normal biliary tract was the prevailing result in both procedures(AU)

Research progress of intraoperative cholangiography in laparoscopic cholecystectomy / 国际外科学杂志

With the widespread implementation of laparoscopic cholecystectomy in various levels of medical institutions, surgical complications have also increased. Among them, the incidence of bile duct injury remains high in complex laparoscopic cholecystectomy. The reason for this is that surgeons cannot effectively and accurately identify the relationship between the aberrant bile duct and the cystic duct and the common bile duct, resulting in the accidental injury of the bile duct, resulting in long hospital stays, increased medical costs, and decreased long-term quality of life for patients. Intraoperative cholangiography, as a real-time visual method of biliary presentation, can effectively reduce the incidence of iatrogenic bile duct injury. However, most surgeons do not fully understand the technology of intraoperative cholangiography during cholecystectomy. This article reviews the application of intraoperative cholangiography in laparoscopic cholecystectomy based on the clinical experience of the author′s team and the literature in recent years, with the aim of deepening the understanding of surgeons about intraoperative cholangiography, so as to better apply it to clinical practice and benefit patients.

Design and application of a new type of biliary-intestinal nutrient tube / 中华危重病急救医学

The establishment of a nutritional pathway is the premise and basis of nutritional therapy for patients with malignant tumor. The nasogastric tube, nasoenteric tube, and percutaneous endoscopic gastric/jejunostomy are commonly used clinical pathways for enteral nutrition (EN) therapy. However, these EN pathways are often difficult to establish in patients with malignant obstructive jaundice (MOJ) with pyloric or duodenum primary obstruction. For this reason, a new type biliary-intestinal nutrient tube placed through percutaneous transhepatic cholangiography drainage (PTCD) pathway was designed by the medical staff of hepatobiliary surgery department of Yinchuan First People's Hospital, and National Utility Model Patent of China were obtained (ZL 2020 2 0283951.5, ZL 2020 2 0288938.9). The new biliary-intestinal nutrient tube has two types: double-lumen tube and single-lumen tube, which consists of tube head, tube body, tail ring and developing ring. The double lumen tube realizes bile internal drainage and EN simultaneously through the double lumen structure of the tube body. The single-lumen tube is used for nutrient infusion after bile duct metal stent implantation, which is not limited by the type of nutrient solution. The tail ring of the two types of nutrient tube is placed in the upper jejunum to reduce retrograde infection and unexpected extubation. Compared with the prior art, the utility model has the advantages of simple structure, reasonable design, safe and effective placement through PTCD pathway, and opens up a new EN path for MOJ patients.

Application of indocyanine green cholangiography in accurate identification of the common bile duct in laparoscopic cholecystectomy / 临床肝胆病杂志

Objective To investigate the application of intraoperative indocyanine green (ICG) cholangiography in the accurate identification of the common bile duct since common bile duct injury is a common complication of laparoscopic cholecystectomy (LC), and to reduce the incidence rate of common bile duct injury during LC. Methods A total of 68 patients who underwent LC in Zhuhai People's Hospital from April 2021 to Jane 2021 were enrolled, among whom 56 patients underwent conventional LC and 12 patients underwent LC under the guidance of ICG cholangiography. The common bile duct, cystic duct, and gallbladder were examined by white light laparoscopy for the conventional LC group and near-infrared laparoscopy for the ICG cholangiography group. The propensity score matching method was used to balance the preoperative data between the two groups. The t -test and the chi-square test were used for comparison of intraoperative blood loss, time of operation, length of postoperative hospital stay, and incidence rate of common bile duct injury between the two groups. Results Compared with the conventional LC group, the ICG cholangiography group had significantly lower intraoperative blood loss 3.1±0.9 mL vs 10.8±2.3 mL, t =-22.709, P < 0.05), significantly shorter time of operation (20.2±1.6 min vs 48.3±5.1 min, t =-19.856, P < 0.05) and length of postoperative hospital stay (1.2±0.3 days vs 2.3±0.8 days, t =-19.507, P < 0.05), and a significantly lower incidence rate of complications (0 vs 8.3%, χ 2 =1.287, P < 0.05). Conclusion ICG cholangiography is an effective method to differentiate between the common bile duct and the cystic duct during LC and can prevent common bile duct injury. This method has great advantages in the treatment of patients with gallstones due to its high degree of identification of the biliary tract, long onset time, repeated application, convenient operation, and ability to be combined with intraoperative navigation device.

Diagnosis and treatment of common biliary complications after orthotopic liver transplantation in adults / 器官移植

Liver transplantation has become an effective treatment for end-stage liver diseases. With rapid development of surgical techniques, donor selection, organ preservation and transportation, immunosuppressants and perioperative management, the overall incidence of complications after liver transplantation has been significantly decreased, whereas the incidence of biliary complications remains relatively high. At present, biliary complications after liver transplantation are still an important cause of graft failure. Nevertheless, the pathogenesis, diagnosis and treatment of biliary complications remain controversial, which are also research hotspots in the field of organ transplantation in recent years. In this article, new breakthrough and research progress upon biliary complications after orthotopic liver transplantation in adults were reviewed, aiming to provide theoretical basis for resolving biliary complications-related clinical issues.

Aneurisma de la aorta abdominal asociado a íctero / Aneurysm of the abdominal aorta associated with icterus

El aneurisma de la aorta abdominal como causa de íctero obstructivo es una situación de excepción en la clínica. El objetivo de esta presentación fue exponer la coexistencia del aneurisma de la aorta abdominal y el íctero. Una asociación muy poco frecuente y de difícil diagnóstico, que coloca al cirujano vascular en la toma de una especial conducta terapéutica. La cuidadosa revisión de los antecedentes patológicos y el análisis del comportamiento clínico del paciente permitieron la solución terapéutica adecuada. Se logró demostrar que el íctero obedecía a una lesión maligna de vías biliares conocida como colangiocarcinoma, que concomitó con la existencia de un aneurisma del V segmento aórtico y no fue el resultado de una compresión extrínseca de la dilatación de la aorta, sobre las vías biliares. La conducta quirúrgica, encaminada a erradicar el íctero y evitar la ruptura aneurismática con resección del aneurisma y colocación de prótesis, no resultó posible por lo avanzado de la lesión tumoral y el grado de metástasis ya establecidos. Solo se realizó resección de la vesícula biliar y seguimiento posterior por oncología(AU)

Abdominal aortic aneurysm as a cause of obstructive icterus is an exceptional situation in the clinic. The aim of this presentation was to expose the coexistence of abdominal aortic aneurysm and icterus. A very rare and difficult to diagnose association, which places the vascular surgeon in a special therapeutic approach. The careful review of the pathological history and the analysis of the patient's clinical behavior allowed the appropriate therapeutic solution. It was possible to demonstrate that the icterus was due to a malignant lesion of the biliary tract known as cholangiocarcinoma, which concomitated with the existence of an aneurysm of the V aortic segment and was not the result of extrinsic compression of the dilatation of the aorta on the biliary tract. The surgical procedure, aimed at eradicating the icterus and avoiding aneurysmal rupture with aneurysm resection and prosthesis placement, was not possible due to the advanced tumor lesion and the degree of metastasis already established. Only gallbladder resection was performed and subsequent follow-up by oncology(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.

Application of near infrared region Ⅱ fluorescence imaging in hepatobiliary surgery / 中华消化外科杂志

Near infrared region Ⅱ (NIR-Ⅱ) fluorescence imaging has made progress in clinical application in recent years and has shown a higher image quality, tumor sensitivity and deeper tissue imaging capability compared to near infrared region Ⅰ imaging in liver neoplasms and biliary tract system. As a real-time intraoperative imaging technology, which can provide high signal to background ratio and deeper tissue penetration, NIR-Ⅱ is able to shorten the duration of operation while improve the safety and therapeutic effect of surgery. It has a great prospect and expanding ability. With the development of a bunch of novel NIR-Ⅱ fluorophores, it is expected to play more important roles in hepatocellular carcinoma targeted imaging, evaluation of bile duct perfusion, distal choledochal imaging and so on. The authors review the progress in the application of NIR-Ⅱ fluorescence imaging in hepatobiliary surgery.

Colangiografía intraoperatoria: curva de aprendizaje en una Residencia de Cirugía General / Intraoperative cholangiography: Learning curve in a General Surgery residency

RESUMEN Antecedentes: el uso de la colangiografía intraoperatoria dinámica (CIOd) durante la colecistectomía laparoscópica (Colelap) sigue siendo un tema en discusión. Objetivos: Este trabajo tiene como objetivo describir y evaluar la curva de aprendizaje y los hallazgos en la CIOd durante las colecistectomías laparoscópicas realizadas por residentes de Cirugía General, incluyéndola como herramienta para una colecistectomía segura, así como entrenamiento para el de sarrollo de habilidades y destrezas. Material y métodos: se incluyeron pacientes con indicación de colecistectomía laparoscópica pro gramada o de urgencia. En las cirugías se realizó tracción según Hunter, visión crítica de seguridad y CIOd sistemática, por un residente mayor y la CIOd por un residente inferior, tutorizado por cirujano de planta. Se evaluaron curva de aprendizaje, tiempos operatorios, relación del tiempo de CIOd con el tiempo de duración de la Colelap (CIO/CX), redisección del cístico y litiasis cística y coledociana. Resultados: se operaron 456 pacientes durante un año (2017-2018). Se observó que, independiente mente de quien realice la CIOd, los residentes pudieron mejorar su curva de aprendizaje, objetiván dose tiempos más cortos para la Colelap, CIOd y la relación CIO/CX. Los coeficientes de aprendizaje fueron mejores en cirugías más complejas en relación con el semestre. El 5,26% presentó litiasis cole dociana (n = 24); de estas, 66,7% tenían litiasis cística (n = 16) y 25% colecistitis (n = 6) asociadas. Todas se resolvieron por vía transcística. No hubo conversiones y se realizó CIOd en el 100%. Conclusión: la CIOd es un procedimiento ideal para ser practicado de manera sistemática durante la Residencia, porque da el entrenamiento necesario para el manejo de la vía transcística, permite evitar una lesión quirúrgica de vía biliar mayor y el diagnóstico de coledocolitiasis.

ABSTRACT Background: The use of dynamic intra-operative cholangiography (dIOC) during laparoscopic cholecystectomy (Lap Chole) remains a topic under discussion. Objectives: This study aims to describe and evaluate the learning curve and findings in the dIOC during laparoscopic cholecystectomies performed by Residents of General Surgery, including it as a tool for a safe cholecystectomy, as well as training for the development of skills and abilities. Material and methods: Patients with indication of scheduled or emergency laparoscopic cholecystectomy were included. In the surgeries, traction was performed according to Hunter, critical safety vision and systematic dIOC, by a senior Resident and the dIOC by a less trained resident, tutored by a staff surgeon. Learning curve, operative times, dIOC time relationship with Lap Chole duration time (IOC/LC), repeated cystic dissection, cystic lithiasis and choledocholithiasis were evaluated. Results: 456 patients were operated for one year (2017-2018). It was observed that regardless of who performs the dIOC, they were able to improve their learning curve, objectifying shorter times for Lap Chole, dIOC and the IOC/LC relationship. The learning coefficients were better in complex surgeries in relation to the semester. 5.26 % had choledocholithiasis (n = 24), of these, 66.7% had cystic lithiasis (n = 16) and 25% associated cholecystitis (n = 6). All were resolved trancystically. There were no conversions and dIOC was performed in 100% of cases. Conclusion: The dIOC is an ideal procedure to be practiced systematically during residency. Because it gives the necessary training for the management of the transcystic pathway, allows avoiding an upper bile duct injury and the diagnosis of choledocholithiasis.

Ascaridiosis en la vía biliar intrahepática: a propósito de un caso pediátrico / Ascariasis in the intrahepatic biliary duct: about a case in pediatrics

El 25 % de la población mundial se encuentra infectada por Ascaris lumbricoides. La ascaridiosis hepatobiliar ocurre en zonas con alta endemicidad y gran carga parasitaria, y genera desde intensa inflamación hasta fibrosis. Se presenta a un paciente de 2 años, que consultó por distensión abdominal y tos de 1 mes de evolución asociada a fiebre en las últimas 72 h. Se realizó una ecografía abdominal que evidenció áscaris en la vía biliar, en el estómago y en el intestino delgado, y una radiografía de tórax con infiltrado inflamatorio intersticial, asociado a hiperleucocitosis con hipereosinofilia y gamma-glutamiltranspeptidasa elevada. Se administró un tratamiento antibiótico, antihelmíntico, sin lograr la eliminación de los parásitos de la vía biliar, por lo que se requirió su extracción mediante colangiografía percutánea

Twenty five percent of the world population is affected by Ascaris lumbricoides. Hepatobiliary ascariasis occurs in areas with high endemicity and great amount of parasitic load, generating intense inflammation to fibrosis. We report a two-year-old patient that consults about abdominal distension and cough of one month of evolution associated with 72 hours of fever. Abdominal ultrasound is performed, which shows bile duct, stomach, small intestine with ascaris and chest x-ray with interstitial inflammatory infiltrate, associated with hyperleukocytosis with hypereosinophilia and elevated gamma-glutamyl transpeptidase. Antibiotic, anthelminthic treatment is administered, without achieving the elimination of the bile duct parasites, requiring their removal by percutaneous cholangiography.

Non-neoplastic cholangiopathies: an algorithmic approach / Colangiopatias não neoplásicas: uma abordagem algorítmica

Abstract Cholangiopathies are chronic diseases that affect the bile ducts, comprising a heterogeneous group of progressive and potentially fatal entities. The diagnosis of these diseases is a great challenge for radiologists because of the overlapping of their clinical, biochemical, and imaging findings. Nevertheless, identifying the precise etiology is crucial, given that the therapeutic options are distinct and influence the prognosis of the patient. The purpose of this review article is to discuss some of the non-neoplastic causes of cholangiopathies and to provide a useful diagnostic algorithm.

Resumo As colangiopatias são doenças crônicas que afetam as vias biliares, constituindo um grupo heterogêneo de doenças progressivas e potencialmente fatais. O seu diagnóstico configura um grande desafio para os radiologistas, uma vez que seus aspectos clínicos, laboratoriais e de imagem se sobrepõem. Apesar disso, a busca etiológica é crucial, tendo em vista que as opções terapêuticas são distintas e influenciam o prognóstico do paciente. O objetivo deste artigo de revisão é discutir algumas das causas não neoplásicas de colangiopatias e fornecer um algoritmo útil na abordagem diagnóstica.

RESUMEN Objetivo : Evaluar la utilidad de la colangiografía retrógrada realizada con enteroscopia asistida por balón simple para el manejo de la patología de la via biliar en pacientes con anatomía alterada por cirugía en la Clínica Anglo Americana. Materiales y métodos : El presente es un estudio descriptivo retrospectivo donde se evalúan a todos los pacientes con anatomía alterada que acudieron por problemas de la via biliar para realizarse una colangiografía retrógrada asistida por enteroscopia con balón simple en la Clínica Anglo Americana durante el periodo de enero del 2014 a enero del 2020. Resultados : Realizamos 10 estudios de colangiografía retrógrada asistida por enteroscopia con balón simple. La canulación de la vía biliar fue exitosa en el 80% de nuestros casos, en dos casos no se pudo localizar la via biliar. Los hallazgos de la colangiografía retrógrada fueron litiasis de via biliar en 7 casos, estenosis de la anastomosis biliodigestiva en 5 casos y un ampuloma. Los procedimientos terapeúticos más frecuentes fueron dilatación con balón progresivo CRE de la anastomosis bilioentérica y extracción de litos con canastilla de Dormia. No se presentaron complicaciones asociadas al procedimiento. Conclusión : La colangiografía retrógrada asistida por enteroscopia con balón simple es un método seguro y eficaz para resolver la patología biliar en nuestros pacientes con anatomía alterada.

ABSTRACT Objective : To evaluate the usefulness of retrograde cholangiography performed with simple balloon-assisted enteroscopy for the management of bile duct pathology in patients with altered anatomy by surgery at the Anglo American Clinic. Materials and methods : This is a retrospective descriptive study where all patients with altered anatomy who came for bile duct problems to undergo a retrograde cholangiography assisted by simple balloon enteroscopy at the Anglo American Clinic during the January period from 2014 to January 2020. Results : We performed 10 studies of retrograde cholangiography assisted by simple balloon enteroscopy. Cannulation of the bile duct was successful in 80% of our cases, in two cases the bile duct could not be located. The findings of the retrograde cholangiography were biliary stones in 7 cases, stenosis of the biliodigestive anastomosis in 5 cases, and an ampuloma. The most frequent therapeutic procedures were CRE progressive balloon dilation of the bilioenteric anastomosis and extraction of stones with a Dormia basket. There were no complications associated with the procedure.

Valor de la colangiografía transcística videolaparoscópica en pacientes con sospecha de coledocolitiasis / Value of the intraoperatory cholangiography videolaparoscopic in patient with choledocholithiasis suspicion

RESUMEN Fundamento: la colangiografía videolaparoscópica se ha convertido en un método diagnóstico y terapéutico en la coledocolitiasis. Objetivos: evaluar el valor de la colangiografía transcística en pacientes con sospecha de coledocolitiasis. Métodos: se realizó un estudio de tipo analítico para interpretar y verificar resultado con el objetivo de analizar la correspondencia entre sospecha de coledocolitiasis y resultado de la colangiografía transcística videolaparoscópica, en el Hospital Militar Clínico Quirúrgico Docente Octavio de la Concepción de la Pedraja, desde abril de 2012 hasta diciembre de 2018. La muestra estuvo compuesta por 62 pacientes con sospecha de coledocolitiasis. Resultados: en el estudio, predominó la sospecha moderada de coledocolitiasis en el sexo femenino a expensas de los estudios ecográficos y de laboratorio, específicamente el aumento en el valor de la fosfatasa alcalina y la dilatación del conducto biliar común entre 8 y 10 mm. Los resultados más frecuentes del proceder fueron; el conducto biliar principal sin alteraciones y adherencias vesiculares. El proceder se extendió por más de 60 minutos en más de la mitad de los casos. La estadía en el hospital después del procedimiento fue menos de tres días y prevaleció un excelente resultado. Conclusiones: las mujeres poseen un índice mayor de sospecha de coledocolitiasis y en un rango moderado. Los criterios de laboratorios y ecográficos prevalecen en estos pacientes, sin embargo, no son específicos de coledocolitiasis. La vía biliar principal sin alteraciones y las adherencias vesiculares son los resultados más frecuentes durante el proceder. El tiempo quirúrgico promedio en este proceder es mayor a 60 minutos. La estadía hospitalaria después del proceder es por lo general menor de tres días. El resultado final con este proceder fue excelente.

ABSTRACT Background: videolaparoscopic cholangiography has become a diagnostic and therapeutic method in choledocholithiasis. Objective: to evaluate the value of transcystic cholangiography in patients with suspected choledocholithiasis. Methods: an analytical study was carried out to interpret and verify the result with the objective of analyzing the correspondence between suspected choledocolithiasis and the result of translastic videolaparoscopic cholangiography, at the Octavio Teaching Surgical Clinical Military Hospital of La Concepción de la Pedraja, since April, 2012 to December, 2018. The sample consisted of 62 patients with suspected choledocolithiasis. Results: in the study, moderate suspicion of choledocholithiasis prevailed in the female sex at the expense of ultrasound and laboratory studies, specifically the increase in the value of alkaline phosphatase and dilation of the common bile duct between 8 and 10 millimeters. The most frequent results of the procedure were; the main bile duct without alterations and vesicular adhesions. The procedure extended for more than 60 minutes in more than half of the cases. The hospital stay after the procedure was less than three days and an excellent result prevailed. Conclusions: women have a higher index of suspicion of choledocholithiasis and in a moderate range. Laboratory and ultrasound criteria prevail in these patients, however, they are not specific to choledocholithiasis. The main bile duct without alterations and vesicular adhesions are the most frequent results during the procedure. The average surgical time in this procedure is more than 60 minutes. The hospital stay after proceeding is usually less than three days. The final result with this procedure is excellent.
