Introduction : Complications of gallstones are an important cause of morbidity in our country and throughout the world and generate high health costs. Objective: The objective of this study was to determine which patients with a complication of their bile duct stone pathology (cholecystitis, acute cholangitis, acute pancreatitis) were previously asymptomatic, and this complication resulted in the onset of the disease. Place: Sanatorium Asociación Española de Socorros Mutuos, Montevideo Uruguay. Design: Descriptive and retrospective observational study with an analysis of medical records. Materials and Methods: 234 clinical cases were analyzed. Epidemiological characteristics, diagnostic methodology, treatments received, and complications were assessed in this group of patients. Results: Of the total number of patients (n=234), 109 (46.6%) had an asymptomatic gallbladder lithiasis and the biliary complication was the debut of their disease. Acute cholecystitis was the most frequent complication (68%), followed by acute cholangitis (22%) and third by acute pancreatitis (10%). The average age of presentation of the disease was 59 years. Conclusions: Almost half of the patients (46.6%) who presented a complication of their gallstones were asymptomatic. This would be an important argument to indicate laparoscopic cholecystectomy with a prophylactic criterion in patients with asymptomatic gallbladder lithiasis.

Factores de riesgo prequirúrgicos para una colecistectomía laparoscópica difícil / Preoperative risk factors for difficult laparoscopic cholecystectomy

RESUMEN Antecedentes: varios estudios observacionales han identificado factores de riesgo (FR) para una colecistectomía laparoscópica difícil (CLD). Objetivo: identificar los FR preoperatorios para CLD en un hospital público de mediana complejidad. Material y métodos: estudio prospectivo de cohorte transversal. Se analizaron 80 pacientes mayores de 18 años sometidos a colecistectomía laparoscópica, entre enero y diciembre de 2019. Se analizaron las variables: edad, sexo, IMC (índice de masa corporal), litiasis vesicular, pancreatitis aguda, colecistitis aguda o crónica, síndrome de Mirizzi, CPRE dentro del mes, numero de cólicos en el último mes, si presentó al menos un cólico en la última semana, leucocitos, enzimas hepáticas mayores, bilirrubina total, hallazgos de ecografía prequirúrgicos, antecedentes de cirugías abdominales previas. Resultados: la incidencia de CLD fue de 47,5%. La tasa de conversión a cirugía convencional fue del 11,25%, el 100% fueron CLD. Los FR para CLD incluyeron sexo masculino (OR: 4,50, IC 95%:1,60-12,62, p: 0,004), cólico en la semana previa a la cirugía (OR:7,17, IC 95%:1,89-27,23, p: 0,004), paredes engrosadas de la vesícula (OR: 4.90, IC 95%:1,90-12,70, p: 0,001), edema perivesicular (OR: 7,14 IC 95%:1,45-35,13 p: 0,016), la vesícula hidrópica (OR: 4,94, IC 95%:1,44-16,88, p: 0,011) y las cirugías previas (OR: 4.38 IC 95%:1,27-15,10 p: 0,001). En el análisis multivariado vemos que los pacientes de sexo masculino y pacientes con cirugías previas presentaban un riesgo elevado para CLD (OR: 6,63 IC 95%:1,75-25,08 p: 0.005; OR: 11.70 IC 95%:1,48-92,37 p: 0,020). Conclusión: se deben centrar los esfuerzos en identificar los pacientes con sospecha de CLD, pudiendo planificar la cirugía y un equipo quirúrgico experimentado.

ABSTRACT Background: The risk factors (RF) for difficult laparoscopic cholecystectomy (DLC) have been identified in many observational studies. Objective: The aim of this study is to identify the preoperative RF for DLC in a secondary care public hospital. Material and methods: We conducted a prospective cross-sectional cohort study of patients > 18 years undergoing laparoscopic cholecystectomy between January and December 2019. The following variables were analyzed: age, sex, body mass index (BMI), cholelithiasis, acute pancreatitis, acute or chronic cholecystitis, Mirizzi syndrome, ERCP within the previous month, episodes of biliary colic in the last month, presence of at least one colic within one week before surgery, white blood cell count, liver enzymes, total bilirubin, preoperative ultrasound and history of upper abdomen surgery. Results: The rate of DLC was 47.5%. Conversion rate to conventional surgery was 11.25% and 100% were categorized as DLC. The RF for DLC included male sex (OR, 4.50; 95% CI,1.60-12.62; p = 0.004), colic within 1 week before surgery (OR, 7.17; 95% CI,1.89-27.23; p = 0.004), gallbladder wall thickening (OR, 4.90; 95% CI,1.90-12.70; p = 0.001), edema around the gallbladder (OR, 7.14; 95% CI, 1.45-35.13; p = 0.016), hidrops gallbladder (OR, 4.94; 95% CI,1.44-16.88; p = 0.011) and previous surgeries (OR, 4.38; 95% CI, 1.27-15.10; p = 0.001). On multivariate analysis, male sex and previous surgery were associated with higher risk of DLC (OR, 6.63; 95% CI,1.75-25.08; p = 0.005; and OR, 11.70, 95% CI,1.48-92.37; p = 0.020, respectively). Conclusion: Efforts should focus on identifying patients with suspicion of DLC to plan surgery with an experienced surgical team.

Asociación entre los factores socioeconómicos y las complicaciones postoperatorias de la colecistectomía / Association between socioeconomic factors and postoperative complications of cholecystectomy

El objetivo de este artículo es determinar si los factores socioeconómicos inciden en las complicaciones posoperatorias de la colecistectomía. Para ello, se definió realizar un estudio de tipo observacional, analítico y enfoque cuantitativo, en 100 pacientes en los que se les realizó colecistectomía. Se aplicó un modelo de regresión logística en el que se incorporaron como variables, factores de riesgo, características socioeconómicas, junto con una variable de control. Se aplicaron tres modelos con variables dependientes alternativas que están delimitadas por el tipo de complicación posoperatoria registrado. Los resultados encontrados mostraron que las mujeres manifiestan un mayor riesgo de presentar complicaciones posteriores a la colecistectomía, igual ocurre en los pacientes de mayor edad. Asimismo el riesgo es mucho menor en las personas con niveles de educación superior y en los pacientes en los que se realizó colecistectomía laparoscópica, alcanzando solo un 5% de riesgo de presentar complicaciones. Las complicaciones posoperatorias luego de la colecistectomía se minimizan al emplear la técnica laparoscópica y los factores socioeconómicos incidirían en el riesgo de padecer complicaciones posoperatorias luego de dicha cirugía, lo que la convierte a la colecistectomía laparoscópica en una operación segura y con muchos otros beneficios y ventajas sobre la cirugía tradicional o convencional.

The article ́s goal isto determine if socioeconomic factors influence the postoperative complications of cholecystectomy. For this, the observational study was defined, analytical and quantitative study was conducted in 100 patients who underwent cholecystectomy. A logistic regression model was applied in which risk factors, socioeconomic characteristics, along with a control variable, were incorporated as variables. Three models were run with alternative dependent variables that are delimited by the type of postoperative complication recorded. The results found showed that women show a higher risk of presenting complications after cholecystectomy, the same occurs in older patients. Likewise, the risk is much lower in people with higher education levels and in patients who underwent laparoscopic cholecystectomy, they only have a 5% risk of presenting complications. Postoperative complications after cholecystectomy are minimized by using the laparoscopic technique and socioeconomic factors would influence the risk of suffering postoperative complications after said surgery, which makes laparoscopic cholecystectomy a safe operation with many other benefits and advantages over traditional or conventional surgery.

Ascariasis hepatobiliar en una lactante con desnutrición severa: reporte de caso / Hepatobiliary ascariasis in severely malnourished infant: case report

Resumen La Ascariasis es la geohelminitiasis más común del mundo, catalogándose como una enfermedad tropical desatendida, que puede causar compromiso pulmonar, gastrointestinal, hepatobiliar y nutricional. Se presenta el caso inusual de una lactante procedente de una zona de extrema pobreza quien consultó por fiebre, vómito, ausencia de deposiciones, distensión y dolor abdominal. Fue diagnosticada con pseudoobstrucción intestinal, desnutrición severa, choque séptico de origen intraabdominal, retraso del neurodesarrollo y deprivación psicoafectiva, cuyas imágenes reportaron ascariasis hepatobiliar y granulomas hepáticos calcificados y abscedados, con infestación severa por Ascaris lumbricoides. Recibió manejo antibiótico y antiparasitario con recuperación exitosa. En nuestro medio, las infecciones por helmintos son causa frecuente de anemia, retraso cognitivo y del crecimiento en niños en edad escolar. Sin embargo, la infestación y complicaciones hepatobiliares como colangitis, colecistitis, pancreatitis, litiasis biliar y hepatitis abscedada son inusuales en menores de dos años. A través de este caso se pretende resaltar la presentación atípica de la enfermedad en lactantes e incitar al fortalecimiento de las intervenciones en salud pública. MÉD.UIS.2020;33(1):67-72.

Abstract Ascariasis is the most common geohelminitiasis in the world. It is categorized as an unattended tropical disease, which can cause pulmonary, gastrointestinal, hepatobiliary and nutritional compromise. We present the unusual case of an infant from an extreme poverty area presenting fever, vomiting, absence of bowel movements, bloating and abdominal pain. She was diagnosed with intestinal pseudoobstruction, severe malnutrition, abdominal septic shock, neurodevelopmental delay and emotional deprivation. The images reported hepatobiliary ascariasis and calcified and abscessed hepatic granulomas, with severe infestation by Ascaris lumbricoides and Trichuris trichiura. She was treated with antibiotics and antiparasitic agents with successful recovery. In our environment, helminth infections are a frequent cause of anemia, stunting and neurodevelopmental delay in school-age children. However, infestation and hepatobiliary complications such as cholangitis, cholecystitis, pancreatitis, biliary lithiasis and hepatic abscess are unusual in children under two years old. Through this case, it is intended to highlight the atypical presentation of this disease at the age of this patient and encourage the strengthening of public health interventions.

Quiste de conducto cístico / Cystic duct cyst

Los quistes congénitos de la vía biliar son infrecuentes y se definen por la dilatación quística del árbol biliar en cualquiera de sus porciones. Los quistes del conducto cístico son aún menos frecuentes. Su etiología permanece incierta y el tratamiento consiste en la resección debido a su potencial desarrollo de malignidad. Presentamos el caso de una paciente en la que se diagnosticó dilatación del conducto cístico y fue tratada por vía laparoscópica.

Congenital biliary duct cysts are rare and are defined as cystic dilatations of the biliary tree in any of its portions. Cystic duct cysts are more uncommon. Their etiology remains uncertain and they should be resected due to the possible development of malignancy. We report the case of a female patient with a diagnosis of dilation of the cystic duct that was treated with laparoscopic surgery.

Effect of controlled hypotension on predicting transfusion response and threshold of stroke variability in hypertensive patients undergoing robotic hepatobiliary surgery / 中南大学学报(医学版)

To investigate the effect of controlled hypotension by urapidil on the predictive accuracy and diagnostic threshold of stroke volume variation (SVV) in hypertensive and non-hypertensive patients undergoing robotic hepatobiliary surgery.
 Methods: Eighty patients undergoing robotic hepatobiliary surgery under general anesthesia were divided into a hypertension group (n=25) and a non-hypertension group (n=38) according to whether or not essential hypertension was present (excluding some cases that didn't meet requirements). The pump speed was at 6.0-7.0 µg/(kg﹒min), and the range of hypotension was between 10%≤Δ systolic blood pressure (SAP)≤20%. Volume loading test was performed after artificial pneumoperitoneum was established in reverse-Trendelenburg position. Hemodynamic indexes including heart rate (HR), SAP, cardiac output (CO), cardiac index (CI), stroke volume (SV), stroke volume index (SVI) and SVV were recorded before and after infusion. Then the receiver operating characteristic (ROC) curves of SVV was drawn to determine the accuracy and diagnosis of SVV in predicting volume status in hypertensive and non-hypertensive patients after anti-Trendelenburg posture and pneumoperitoneum.
 Results: In the patients with controlled hypotension by urapidil, the area under the ROC curve of SVV in the hypertension group was 0.974, the diagnostic threshold was 13.5%, the ROC curve of SVV in the non-hypertension group was 0.832, and the diagnostic threshold was 15.5%.
 Conclusion: SVV can accurately predict the volume status in the hypertension group and the non-hypertension group after controlled hypotension in the anti-Trendelenburg position and fixed pneumoperitoneal pressure, and the SVV diagnostic threshold in the non-hypertensive group is higher than that in the hypertensive group.

Role of Image-Enhanced Endoscopy in Pancreatobiliary Diseases

Recent advances in cholangiopancreatoscopy technology permit image-enhanced endoscopy (IEE) for pancreatobiliary diseases. There are limitations in endoscopy performance and in the study of the clinical role of IEE in bile duct or pancreatic duct diseases. However, currently available IEEs during cholangiopancreatoscopy including traditional dye-aided chromoendoscopy, autofluorescence imaging, narrow-band imaging, and i-Scan have been evaluated and reported previously. Although the clinical role of IEE in pancreatobiliary diseases should be verified in future studies, IEE is a useful promising tool in the evaluation of bile duct or pancreatic duct mucosal lesions.

Understanding the Biliary Dyspepsia / 대한췌담도학회지

Functional dyspepsia is a very common disease and there are two types of dyspepsia. One is functional dyspepsia in the gastrointestinal tract and the other is pancreatobiliary dyspepsia. Biliary dyspepsia is caused by biliary tract disease and can even cause biliary pain. Acalculous biliary pain (ABP) is biliary colic without gallstones, it is caused by functional biliary disorder or structural disorders such as microlithiasis, sludges or parasitic infestation like Clonorchiasis. The endoscopic ultrasonography is helpful tool for differential diagnosis of ABP. Although sphincter of Oddi manometry (SOM) is performed for the confirmative diagnosis of sphincter of Oddi dysfunction (SOD), several non-invasive tests have been studied because of some practical limitations and invasiveness of SOM itself. In fact, the most clinically used easy test to diagnose functional biliary disorder is quantitative hepatobiliary scintigraphy and it can distinguish gallbladder dyskinesia, SOD, or combined type. Initial treatment of functional biliary disorder is adequate dietary control and medication, but if the symptoms worsened or recurred frequently, laparoscopic cholecystectomy could be performed with gallbladder dyskinesia. If SOD is suspected, additional SOM should be considered and endoscopic sphincterotomy (EST) can be done according to the outcome. If the SOM is not available, the patient could be diagnosed by stimulated ultrasound.

A Case of Fitz-Hugh-Curtis syndrome in a male patient / 고신대학교의과대학학술지

Fitz-Hugh-Curtis syndrome has been described as perihepatitis associated with pelvic inflammatory disease (PID). It is classically seen in premenopausal young women who have right upper quadrant pain, usually but not always accompanied by symptoms of PID, and is frequently confused with biliary tract disease. However, the syndrome has rarely been reported in males. The predominant symptom is right upper quadrant pain, but PID may not be present in male patients. Here, we report a case of Fitz-Hugh-Curtis syndrome in a young male patient, which was diagnosed by serological tests and computed tomography. Fitz-Hugh-Curtis syndrome should be considered as a possible cause of pain in the right upper quadrant in male patients, although such a case is very rare.

Biliary complications after liver transplantation / Complicações biliares pós-transplante hepático

ABSTRACT Background: Biliary reconstitution has been considered the Achilles's heel of liver transplantations due to its high rate of postoperative complications. Aim: To evaluate the risk factors for occurrence of biliary strictures and leakages, and the most efficient methods for their treatment. Method: Of 310 patients who underwent liver transplantation between 2001 and 2015, 182 medical records were retrospectively analyzed. Evaluated factors included demographic profile, type of transplantation and biliary reconstitution, presence of vascular and biliary complications, their treatment and results. Results: 153 (84.07%) deceased donor and 29 (15.93%) living donor transplantations were performed. Biliary complications occurred in 49 patients (26.92%): 28 strictures (15.38%), 14 leakages (7.7%) and seven leakages followed by strictures (3.85%). Hepatic artery thrombosis was present in 10 patients with biliary complications (20.4%; p=0,003). Percutaneous and endoscopic interventional procedures (including balloon dilation and stent insertion) were the treatment of choice for biliary complications. In case of radiological or endoscopic treatment failure, surgical intervention was performed (biliodigestive derivation or retransplantation (32.65%). Complications occurred in 25% of patients treated with endoscopic or percutaneous procedures and in 42.86% of patients reoperated. Success was achieved in 45% of patients who underwent endoscopic or percutaneous procedures and in 61.9% of those who underwent surgery. Conclusion: Biliary complications are frequent events after liver transplantation. They often require new interventions: endoscopic and percutaneous procedures at first and surgical treatment when needed. Hepatic artery thrombosis increases the number of biliary complications.

RESUMO Racional: A reconstituição biliar é considerada o calcanhar-de-Aquiles do transplante hepático devido à sua elevada taxa de complicações pós-operatórias. Objetivo: Analisar os fatores de risco para ocorrência de estenoses e fístulas biliares e os métodos terapêuticos mais eficientes para seu tratamento. Método: De 310 pacientes transplantados entre 2001 e 2015, 182 prontuários foram analisados retrospectivamente. Foram avaliados o perfil demográfico dos pacientes, tipo de transplante e reconstituição biliar, presença de complicações biliares e vasculares, tratamento utilizado e seus resultados. Resultados: Foram realizados 153 (84,07%) transplantes hepáticos cadavéricos e 29 intervivos (15,93%). Complicações biliares ocorreram em 49 pacientes (26,92%): 28 estenoses (15,38%), 14 fístulas (7,7%) e sete fístulas seguidas de estenose (3,85%). Trombose de artéria hepática esteve presente em 10 pacientes com complicações biliares (20,4%, p=0,003). Os tratamentos de escolha foram os procedimentos endoscópicos ou percutâneos (incluindo dilatação por balão e colocação de próteses (40,82%). No insucesso deles, foi realizado tratamento cirúrgico (derivação biliodigestiva ou retransplante (32,65%). Complicações ocorreram em 25% dos pacientes que fizeram procedimentos endoscópicos ou percutâneos e em 42,86% dos submetidos ao tratamento cirúrgico. A resolução das complicações biliares foi de 45% com os procedimentos endoscópicos ou percutâneos e de 61,9% com o cirúrgico. Conclusão: Complicações biliares são frequentes após transplante hepático. Comumente requerem novas intervenções. Os procedimentos endoscópicos e percutâneos são a primeira escolha e os cirúrgicos, empregados na falha destes. Trombose de artéria hepática aumenta a incidência de complicações biliares.

Introducción: Las lesiones de la vía biliar (LVB) iatrogénicas durante una colecistectomía constituyen una complicación grave, con una significativa morbimortalidad. El objetivo del estudio es analizar los resultados de la reparación de las LVB poscolecistectomía realizadas entre los años 2000 y 2015. Métodos: Estudio de serie de casos. Se consignaron en una base de datos: variables demográficas, el centro donde se realizó la colecistectomía, la vía de reparación, el tipo de LVB, el tipo de reparación efectuada, las complicaciones postoperatorias, la mortalidad operatoria y la sobrevida. Para el análisis estadístico se utilizó el software SPSS 22 (SPSS Inc., Chicago, IL, EE. UU.). Resultados: Se estudiaron 36 pacientes, de los cuales 33 (92%) fueron mujeres; la edad promedio fue de 48,5 ± 14 años. La colecistectomía que originó la iatrogenia fue laparoscópica en 24 (67%) casos. La LVB fue identificada en el intraoperatorio en 9 pacientes (25%). La LVB más frecuente se localizó a menos de 2cm de la confluencia (Bismuth-Strasberg tipo E2) en 14 (39%) pacientes. La derivación biliodigestiva con asa en Y de Roux fue la técnica más utilizada en la reparación de las LVB en 26 (72%) casos. A largo plazo, se observó una estenosis en 7 (19%) pacientes, con necesidad de una nueva reparación. Hubo mortalidad operatoria de un paciente (3%). Conclusiones: Las LVB poscolecistectomía fueron satisfactoriamente reparadas preferentemente con una derivación biliodigestiva con Y de Roux en nuestro centro.

Abstract Introduction: Iatrogenic bile duct injuries (BDI) during a cholecystectomy are a serious complication with significant morbidity and mortality. The aim of this study is to analyze the results BDI's repair post cholecystectomy which was performed between the years 2000-2015. Methods: Case series study. Demographic variables, the center where the cholecystectomy was performed, repair pathway, the type of bile duct injury, the type of reparation performed, postoperative complications, operative mortality and survival were entered in a database. For statistical analysis, software SPSS 22 was used. Results: Thirty-six patients were studied; 33 (92%) were women; mean age 48.5 ± 14 years. The Cholecystectomy that originated the iatrogenia was laparoscopic in 24 (67%) cases. BDI was identified intraoperatively in 9 patients (25%). The most common BDI was located less than 2 cm to confluence (Bismuth-Strasberg type E2) in 14 (39%) patients. The biliodigestive Roux-Y bypass was the most used technique in the repair of the BDI in 26 (72%) cases. In the long term, stenosis was observed in 7 (19%) patients with the need of a new repair. Operative mortality of 1 patient (3%). Conclusions: BDI post cholecystectomy were successfully repaired preferably with a biliodigestive Roux-Y bypass in our center.

An Update on Endoscopic Management of Post-Liver Transplant Biliary Complications

Biliary complications are the most common post-liver transplant (LT) complications with an incidence of 15%–45%. Furthermore, such complications are reported more frequently in patients who undergo a living-donor LT compared to a deceased-donor LT. Most post-LT biliary complications involve biliary strictures, bile leakage, and biliary stones, although many rarer events, such as hemobilia and foreign bodies, contribute to a long list of related conditions. Endoscopic treatment of post-LT biliary complications has evolved rapidly, with new and effective tools improving both outcomes and success rates; in fact, the latter now consistently reach up to 80%. In this regard, conventional endoscopic retrograde cholangiopancreatography remains the preferred initial treatment. However, percutaneous transhepatic cholangioscopy is now central to the management of endoscopy-resistant cases involving complex hilar or multiple strictures with associated stones. Many additional endoscopic tools and techniques—such as the rendezvous method, magnetic compression anastomosis , and peroral cholangioscopy—combined with modified biliary stents have significantly improved the success rate of endoscopic management. Here, we review the current status of endoscopic treatment of post-LT biliary complications and discuss conventional as well as the aforementioned new tools and techniques.

Prevalence and Related Factors of Clonorchiasis among Five Major Riverside Residents in South Korea

PURPOSE: This study attempted to investigate the prevalence and related factors of Clonorchiasis among five major riverside residents in South Korea. METHODS: This study is descriptive research, nationwide survey, and the subjects are 23,492 residents selected by convenience sampling. Data collection was conducted between March 1 and June 30, 2011, and stool collection and questionnaire survey were conducted by affiliated public health centers in 38 cities and Gun's. RESULTS: The prevalence rates of Clonorchiasis in the five major riversides were as follows: the Guem River 15.2%; the Nakdong River 11.9%; the Seomjin River 10.9%; the Han River 5.7%; and the Yeongsan River 3.9%. The prevalence rates were shown to be significantly high among people who had highly frequent experiences of eating and cooking freshwater raw fish, were diagnosed with liver and/or biliary tract diseases, and drank less than once a month. CONCLUSION: These results suggest that it is necessary to improve awareness of Clonorchiasis and provide intensive public health education for the riverside residents. And the target groups should be set up by reflecting the characteristics of at-risk groups, and it is necessary to prepare customized strategies for prevention and management of Clonorchiasis.

ERCP and Direct Cholangioscopy with Gastroscope in Patients with Ectopic Opening of the Bile Duct into the Duodenal Bulb: A Report of 3 Cases / 대한췌담도학회지

Ectopic openings of the common bile duct into the duodenal bulb, which are associated with biliary tract disease or recurrent/refractory duodenal ulcers, are rare. We report three such cases, all of which were documented with gastroscope, and two of which were managed with endoscopic retrograde cholangiopancreatography (ERCP) via gastroscope. We suggest that ERCP can be performed with gastroscope, since it may offer a better working position in certain cases.

Predictors of Mortality in Korean Patients with Pyogenic Liver Abscess: A Single Center, Retrospective Study / 대한소화기학회지

BACKGROUND/AIMS: The mortality rate of pyogenic liver abscess (PLA) has decreased dramatically, but it remains a potentially life threatening disease. Most cases are cryptogenic or occur in elderly men with underlying biliary tract disease. Although several studies have addressed the characteristics and etiology of PLA, research on factors affecting PLA-associated mortality is lacking. This study intended to identify the clinical and radiological features, pathogens, complications, and predictors of mortality in Korean PLA patients. METHODS: The medical records of 231 PLA patients diagnosed at Yeungnam University Medical Center between January 2010 and January 2014 were analyzed. A diagnosis of PLA was made based on imaging studies and blood and abscess cultures. The clinical, radiological, and laboratory findings of patients were analyzed. RESULTS: The mean patient age was 64.0±12.9 years and the male to female ratio was 1.5:1. Klebsiella pneumoniae was the predominant organism isolated from hepatic abscesses (69.9%) and blood (74.2%). The most common complication was pleural effusion (35.8%) and most common co-infection was cholangitis (8.2%). The overall mortality rate of PLA was 6.9% (16/231), and was significantly higher in patients with a history of liver abscess (OR 5.970, 95% CI 1.207-29.529; p=0.028), bilirubinemia (>2 mg/dL) (OR 9.541, 95% CI 2.382-38.216; p=0.001), thrombocytopenia (<140×10(3)/µL) (OR 4.396, 95% CI 1.130-17.106; p=0.033), or anemia (<12 g/dL) (OR 13.277, 95% CI 1.476-119.423; p=0.021). CONCLUSIONS: The prognosis of PLA appears to be dependent on underlying pathologies and severity of condition. More aggressive treatment should be considered if a poor prognosis is expected.

Current Status of Biliary Metal Stents

Many advances have been achieved in biliary stenting over the past 30 years. Endoscopic stent placement has become the primary management therapy to relieve obstruction in patients with benign or malignant biliary tract diseases. Compared with plastic stents, a self-expandable metallic stent (SEMS) has been used for management in patients with malignant strictures because of a larger lumen and longer stent patency. Recently, SEMS has been used for various benign biliary strictures and leaks. In this article, we briefly review the characteristics of SEMS as well as complications of stent placement. We review the current guidelines for managing malignant and benign biliary obstructions. Recent developments in biliary stenting are also discussed.

Bacteriemias por Streptococcus gallolyticus (ex S. bovis) y su relación con patología colónica o hepatobiliar y endocarditis / Streptococcus gallolyticus (ex S. bovis) bacteremia and its relationship with colonic or hepatobiliary disease and endocarditis

Background: Bacteremia due to Streptococcus bovis (now S. gallolyticus) has been traditionally associated to colon or hepatobiliar disease and endocarditis but there is no information on this matter in Chile. Aims: To describe clinical features of adult patients suffering bacteremia by S. bovis/S. gallolyticus, identify the source of the bacteremia and the frequency of endocarditis. Methods: Retrospective-descriptive study using laboratory records. Results: Between January 2003 and August 2014, 23 S. bovis/S. gallolyticus bacteremic events were identified among 22 patients. Mean age was 72.7 years (range 46-96). Co-morbidities were frequent (9.1 to 47.6%). The primary source of bacteremia was intestinal in 52.2%; hepatobiliar in 17.4% and in 34.8% it was not elucidated. Six patients had infective endocarditis (26.1%) and one patient had espondylodiscitis (4.3%). S. bovis represented 39.1% of isolates (all until 2008), S. gallolyticus subsp pasteurianus 39.1% and, S. gallolyticus subsp infantarius and S. gallolyticus subsp gallolyticus 8.7% each one, respectively. Association studies between the bacteremic source or endocarditis with specific S. gallolyticus subspecies were limited by the small number of isolates. Seven patients (30.4%) underwent surgical interventions. In-hospital mortality reached 21.7% (n = 5). Conclusions: Although infrequent, bacteremic events by S. gallolyticus/S. bovis have increased in-hospital mortality, require surgical intervention and affect older patients with co-morbidities. Near two-thirds suffer from colonic or hepatobiliary disease that act as the primary source of bacteremia. In addition, near one fourth is affected by infective endocarditis. Detection of S. gallolyticus/S. bovis in blood cultures prompts a thorough clinical evaluation in order to clarify the source of the bloodstream infection and the presence of complications.

Antecedentes: Los cuadros de bacteriemia por Streptococcus bovis (actualmente S. gallolyticus) han sido tradicionalmente asociados a patología colónica o hepatobiliar y endocarditis pero no se conoce de estudios en Chile que hayan abordado este tema. Objetivos: Describir aspectos clínicos de pacientes adultos afectados por bacteriemias por S. bovis/S. gallolyticus, identificar la fuente de la bacteriemia y la frecuencia de endocarditis. Métodos: Diseño de tipo retrospectivo, descriptivo, con el registro de casos bacteriemia. Resultados: Entre enero de 2003 y agosto de 2014 se identificaron 23 eventos de bacteriemia por S. bovis/S. gallolyticus en 22 pacientes. La edad promedio fue de 72,7 años (rango 46-96). La prevalencia de diferentes co-morbilidades fue elevada (9,1 a 47,6%). El foco primario de la bacteriemia fue intestinal en 52,2%, hepatobiliar en 17,4% y, en 34,8% no se aclaró el foco. Seis pacientes presentaron endocarditis infecciosa (26,1%) y uno espondilodiscitis (4,3%). S. bovis representó 39,1% de los aislados (todos hasta el 2008), S. gallolyticus subsp pasteurianus 39,1%, S. gallolyticus subsp infantarius y S. gallolyticus subsp gallolyticus 8,7%, respectivamente. Los estudios de asociación estuvieron limitados por el bajo número de aislados. Siete pacientes (30,4%) debieron ser intervenidos quirúrgicamente. La mortalidad hospitalaria fue de 21,7% (n: 5). Conclusiones: Aunque infrecuentes, los eventos de bacteriemia por S. gallolyticus/S. bovis tienen una elevada mortalidad hospitalaria, requieren con frecuencia procedimientos quirúrgicos y afectan a pacientes mayores con co-morbilidades. Cerca de dos tercios padecen de una patología colónica o hepatobiliar que actúa como foco primario y cerca de un cuarto presenta endocarditis infecciosa. La detección de este grupo bacteriano en los hemocultivos requiere una evaluación para establecer el origen de la bacteriemia y la presencia de complicaciones.

Efficacy and Safety of Pancreatobiliary Endoscopic Procedures during Pregnancy

BACKGROUND/AIMS: Endoscopic therapy with endoscopic retrograde cholangiopancreatography (ERCP) has been suggested as an effective diagnostic and therapeutic tool for biliary and pancreatic disorders during pregnancy. In this report, we describe our experiences with pancreatobiliary endoscopic procedures during pregnancy. METHODS: We reviewed ERCP and endoscopic ultrasonography (EUS) procedures that were performed at a single tertiary care referral center between January 2002 and October 2013. Medical records were reviewed for the procedure indication, the duration of fluoroscopy, postprocedure complications, etc. Pregnancy outcomes and fetal complications were identified by chart review and phone calls to patients. RESULTS: A total of 10 ER-CPs and five EUSs were performed in 13 pregnant patients: four of whom underwent the procedure in the first trimester, eight in the second trimester, and one in the third trimester. Indications for endoscopic therapy included gallstone pancreatitis, obstructive jaundice with common bile duct (CBD) stone, asymptomatic CBD stone, pancreatic cyst, choledochal cyst, and acute cholecystitis. Only one patient had a complication, which was postprocedural hyperamylasemia. Two patients underwent an artificial abortion, one according to her own decision and the other due to an adverse drug reaction. CONCLUSIONS: ERCP seems to be effective and safe for pregnant women. Additionally, EUS can be an alternative to ERCP during pregnancy.

Biliary Cast Syndrome: Hepatic Artery Resistance Index, Pathological Changes, Morphology and Endoscopic Therapy / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Biliary cast syndrome (BCS) was a postoperative complication of orthotopic liver transplantation (OLT), and the reason for BSC was considered to relate with ischemic type biliary lesions. This study aimed to evaluate the relationship between BCS following OLT and the hepatic artery resistance index (HARI), and to observe pathological changes and morphology of biliary casts.</p><p><b>METHODS</b>Totally, 18 patients were diagnosed with BCS by cholangiography following OLT using choledochoscope or endoscopic retrograde cholangiopancreatography. In addition, 36 patients who did not present with BCS in the corresponding period had detectable postoperative HARI on weeks 1, 2, 3 shown by color Doppler flow imaging. The compositions of biliary casts were analyzed by pathological examination and scanning electron microscopy.</p><p><b>RESULTS</b>HARI values of the BCS group were significantly decreased as compared with the non-BCS group on postoperative weeks 2 and 3 (P < 0.05). Odds ratio (OR) analysis of HARI 1, HARI 2, HARI 3 following the operation was >1 (OR = 1.300; 1.223; and 1.889, respectively). The OR of HARI 3 was statistically significant (OR = 1.889; 95% confidence interval = 1.166-7.490; P = 0.024). The compositions of biliary casts were different when bile duct stones were present. Furthermore, vascular epithelial cells were found by pathological examination in biliary casts.</p><p><b>CONCLUSIONS</b>HARI may possibly serve as an independent risk factor and early predictive factor of BCS. Components and formation of biliary casts and bile duct stones are different.</p>
