Tratamiento de la Colecisto-coledocolitiasis mediante la técnica de Rendez-vous laparo-endoscópico: implementación y desarrollo de la técnica en un hospital universitario

Objetivo: La litiasis biliar es una patología frecuente en Chile y el mundo, que suele presentarse como colecistocoledocolitiasis. Dentro de las alternativas para su manejo está el rendez-vous laparoendoscópico (RVLE), que consiste en una colecistectomía laparoscópica asociada a colangiopancreatografía endoscó-pica retrograda (ERCP). Este trabajo tiene como objetivo evaluar la implementación de esta técnica para el tratamiento de la colecistocoledocolitiasis en un hospital universitario. Materiales y Métodos: Cohorte retrospectiva de 4 años de pacientes con colecistocoledocolitiasis en quienes se realizó un RVLE. Resultados: Se incluyeron 296 pacientes, de edad promedio de 52 años, siendo un quinto mayor de 70 años, y presentando un 29,3% comorbilidades significativas. Un 65,2% fueron urgencias y un 12,2% presentó colangitis aguda. El éxito de la técnica fue de un 82,8%. Los cálculos mayores de 5 mm se asociaron al fracaso de ésta. La principal causa de fracaso fue el no paso de la guía hacia el duodeno (13,5%). La morbilidad, clínicamente significativa, fue de 9,5% y la mortalidad global a los 90 días fue de 0,68%. Discusión: El RVLE es un tratamiento eficaz para la colecistocoledocolitiasis en un tiempo quirúrgico, incluso en pacientes mayores de 70 años con comorbilidades, aunque con mayor morbilidad en colangitis aguda. La colangioresonancia magnética es útil en el diagnóstico y aporta información como el tamaño de los cálculos. El no paso de la guía es la principal causa de fracaso, pero se resuelve en la mayoría de los casos con una ERCP tradicional.

Objective: Gallstone disease is a common condition in Chile and worldwide, often manifesting as cholecystocholedocholithiasis. One of the treatment options is laparoendoscopic rendezvous (RVLE), involving laparoscopic cholecystectomy combined with endoscopic retrograde cholangiopancreatography (ERCP). This study aims to assess the effectiveness of this technique in managing cholecystocholedocholithiasis at a university hospital. Materials and Methods: A retrospective cohort study spanning four years was conducted on patients diagnosed with cholecystocholedocholithiasis who underwent RVLE. Results: The study included 296 patients, with an average age of 52 years. One-fifth of them were over 70 years old, and 29.3% had significant comorbidities. Of these cases, 65.2% were classified as emergencies, and 12.2% presented with acute cholangitis. The overall success rate of the RVLE procedure was 82.8%. Notably, the presence of gallstones larger than 5 mm was associated with a higher likelihood of procedure failure. The primary reason for failure was the inability of the guidewire to advance into the duodenum (13.5%). Clinically significant morbidity occurred in 9.5% of cases, and the overall mortality rate at 90 days was 0.68%. Discussion: RVLE is an effective treatment for cholecystocholedocholithiasis within a single surgical intervention, even in patients over 70-years-old with comorbidities. However, it is important to note that the procedure is associated with increased morbidity when performed in cases of acute cholangitis. Magnetic resonance cholangiopancreatography serves as a valuable diagnostic tool, providing insights into stone size. The most common cause of procedure failure is the inability of the guidewire to pass through, although this issue can often be resolved with a traditional ERCP.

Association between hypertension and the risk of gallstone disease / 临床肝胆病杂志

ObjectiveThis article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study， a systematic review， and a meta-analysis. MethodsThe study was conducted in three stages. In the first stage， subjects were recruited for health examination in four hospitals in Chengdu， Tianjin， Beijing， and Chongqing， China， from 2015 to 2020， and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center. In the second stage， Embase， PubMed， Wanfang Data， VIP， and CNKI databases were searched for related studies published up to May 2021， and a meta-analysis was conducted to further verify such association. In the third stage， the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature. ResultsA total of 633 948 participants were enrolled in the cross-sectional study， and the prevalence rate of GSD was 7.844%. The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD（P<0.05）. Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes， ages， and subtypes of GSD. A total of 80 articles were included in the systematic review and the meta-analysis， and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure. ConclusionHypertension significantly increases the risk of GSD， and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.

Association between the risk of increase in total cholesterol and the risk of cholelithiasis： A bidirectional Mendelian randomization study / 临床肝胆病杂志

ObjectiveTo investigate the association between the risk of increase in total cholesterol （TC） and the risk of cholelithiasis by using bidirectional Mendelian randomization （MR）. MethodsThe open gwas public database was used to obtain the single nucleotide polymorphism data associated with TC and cholelithiasis， and a secondary data analysis was performed for all summary data of genome-wide association studies. The genetic loci closely associated with TC or cholelithiasis were selected as exposure or outcome variables， and the bidirectional MR analysis was performed using the methods such as Egger regression， Weighted median， IVW random effects model， and IVW fixed effects model， with odds ratio （OR） values for evaluating the causal relationship between TC and cholelithiasis. ResultsWith TC as the exposure and cholelithiasis as the outcome， TC-cholelithiasis had an overall OR value of 0.91 （95% confidence interval ［CI］： 0.85‍ ‍—‍ ‍0.97） before elimination of heterogeneity and 0.93 （95%CI： 0.89‍ ‍—‍ ‍0.97） after elimination of heterogeneity. With cholelithiasis as the exposure and TC as the outcome， TC-cholelithiasis had an overall OR value of 0.20 （95%CI： 0.06‍ ‍—‍ ‍0.65） before elimination of heterogeneity and 0.28 （95%CI： 0.10‍ ‍—‍ ‍0.83） after elimination of heterogeneity. There was a bidirectional causal relationship between genetically predicted TC and cholelithiasis. ConclusionThis study confirms the bidirectional causal relationship between TC and cholelithiasis. The risk of cholelithiasis decreases with the increase in alleles associated with the elevation of TC level； on the contrary， the risk of elevated TC level decreases with the increase in alleles associated with the onset of cholelithiasis.

Colecistectomía con exploración de vías biliares laparoscópica en paciente con situs inversus totalis

Se presenta el caso de un paciente varón de 77 años con diagnóstico de colecistitis crónica calculosa y coledocolitiasis, con antecedente de situs inversus totalis. Se le realizó una colecistectomía con exploración de vías biliares laparoscópica, utilizando la "técnica francesa en espejo", con extracción de los cálculos. El paciente evolucionó favorablemente. El objetivo del presente trabajo es dar a conocer el caso clínico que es poco frecuente su reporte en la literatura mundial (solo 9 casos). Su importancia radica en que sería el primer reporte de caso clínico publicado de una colecistectomía y exploración de vías biliares laparoscópica con retiro del cálculo en colédoco en un paciente con situs inversus totalis, realizado en el Perú.

We present the case of a 77-year-old male patient with a diagnosis of chronic calculous cholecystitis and choledocholithiasis, with a history of situs inversus totalis. Therefore, a laparoscopic cholecystectomy with common bile duct exploration were performed, using the "french mirror technique", with stone extraction. Patient evolved favorably. The aim of this study is to present this clinical case that is rarely reported in the world literature (only 9 cases). Its importance lies in the fact that it would be the first published clinical case report of a laparoscopic cholecystectomy and bile duct exploration with removal of the common bile duct stones in a patient with situs inversus totalis, performed in Peru.

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.

Factores asociados con la conversión a técnica abierta en la colecistectomía laparoscópica / Factors associated with conversion to open technique in laparoscopic cholecystectomy

Introducción. La colecistectomía laparoscópica es el estándar de oro para el manejo de la patología de la vesícula biliar con indicación quirúrgica. Durante su ejecución existe un grupo de pacientes que podrían requerir conversión a técnica abierta. Este estudio evaluó factores perioperatorios asociados a la conversión en la Clínica Central OHL en Montería, Colombia. Métodos. Estudio observacional analítico de casos y controles anidado a una cohorte retrospectiva entre 2018 y 2021, en una relación de 1:3 casos/controles, nivel de confianza 95 % y una potencia del 90 %. Se caracterizó la población de estudio y se evaluaron las asociaciones según la naturaleza de las variables, luego por análisis bivariado y multivariado se estimaron los OR, con sus IC95%, considerando significativo un valor de p<0,05, controlando variables de confusión. Resultados. El estudio incluyó 332 pacientes, 83 casos y 249 controles, mostrando en el modelo multivariado que las variables más fuertemente asociadas con la conversión fueron: la experiencia del cirujano (p=0,001), la obesidad (p=0,036), engrosamiento de la pared de la vesícula biliar en la ecografía (p=0,011) y un mayor puntaje en la clasificación de Parkland (p<0,001). Conclusión. La identificación temprana y análisis individual de los factores perioperatorios de riesgo a conversión en la planeación de la colecistectomía laparoscópica podría definir qué pacientes se encuentran expuestos y cuáles podrían beneficiarse de un abordaje mínimamente invasivo, en búsqueda de toma de decisiones adecuadas, seguras y costo-efectivas

Introduction. Laparoscopic cholecystectomy is the gold standard for the management of gallbladder pathology with surgical indication. During its execution, there is a group of patients who may require conversion to the open technique. This study evaluated perioperative factors associated with conversion at the OHL Central Clinic in Montería, Colombia. Methods. Observational analytical case-control study nested in a retrospective cohort between 2018 and 2021, in a 1:3 case/control ratio, 95% confidence level and 90% power. The study population was characterized and the associations were evaluated according to the nature of the variables, then the OR were estimated by bivariate and multivariate analysis, with their 95% CI, considering a value of p<0.05 significant, controlling for confounding variables. Results. The study included 332 patients, 83 cases and 249 controls, showing in the multivariate model that the variables most strongly associated with conversion were: the surgeon's experience (p=0.001), obesity (p=0.036), gallbladder wall thickening on ultrasonography (p=0.011), and a higher score in the Parkland classification (p<0.001). Conclusions. Early identification and individual analysis of the perioperative risk factors for conversion in the planning of laparoscopic cholecystectomy could define which patients are exposed, and which could benefit from a minimally invasive approach, in search of making safe, cost-effective, and appropriate decisions

Unusually large number of gall stones removed through laparoscopic cholecystectomy from a single patient- A case report

Gallstone disease is characterized by the formation of calculi in the gall bladder or the biliary tract. It may be asymptomatic or present as biliary colic or with complicated disease. Laparoscopic cholecystectomy is the mainstay of treatment for symptomatic gall stones. We describe a case of Gallstone disease in a 43-year-old female, where over seven thousand stones were removed through a Laparoscopic procedure.

Introducción: El situs inversus totalis es una condición congénita en la cual los órganos torácicos y abdominales se encuentran en posición contraria a la posición habitual. En la literatura quirúrgica internacional se encuentran publicados no más de 55 casos de colecistectomía en pacientes con situs inversus totalis. La resolución laparoscópica de una paciente en nuestra Institución nos permite revisar esta particular condición patológica. Caso Clínico: Paciente femenino de 43 años de edad hospitalizada por una colecistitis aguda la cual es resuelta por vía laparoscópica sin incidentes. Material y Método: Se resume la literatura actual mediante una extensa revisión en PubMed de los reportes más relevantes. Considerando que todos los artículos publicados son casos clínicos o pequeñas series de casos, se presentan los resultados de esta revisión en tablas con estadística descriptiva básica. Discusión: Se discuten las características generales de estos pacientes, la presentación clínica, diagnóstico y técnica quirúrgica. Conclusión: La colecistectomía laparoscópica constituye el estándar de oro en pacientes con situs inversus y patología biliar, la cual debe ser realizada por un cirujano experimentado acomodando los trocares apropiadamente, debido a las dificultades técnicas que se encuentran en estos pacientes por las anomalías anatómicas propias de esta condición. El diagnóstico radiológico actual permite la planificación del abordaje y del procedimiento quirúrgico apropiado para cada paciente.

Introduction: Situs inversus totalis is a congenital condition in which the thoracic and abdominal organs are in the opposite position from normal anatomy. We found no more than 55 cases of cholecystectomy in patients with situs inversus totalis published in the international surgical literature. The laparoscopic resolution of a patient in our Institution allows us to review this particular pathological condition. Clinical Case: A 43-year-old female patient was admitted for acute cholecystitis and was resolved laparoscopically without any incidents. Material and Method: We summarized the current literature through an extensive PubMed review of the most relevant reports. Considering that all published articles are clinical cases or small case series, we present the results of this review in a table with basic descriptive statistics. Discussion: We discuss the general characteristics of these patients, clinical presentation, diagnosis, and surgical technique. Conclusions: Laparoscopic cholecystectomy is the gold standard in patients with situs inversus and biliary pathology, which must be performed by an experienced surgeon, properly accommodating the trocars due to the technical difficulties in these patients secondary to anatomical anomalies typical of this condition. Current radiological diagnosis allows planning the appropriate approach and surgical procedure for each patient.
