OBJETIVO: determinar la microbiología y la prevalencia de cultivos de bilis positivos en la Colecistitis Aguda (CA). METODOLOGÍA DE LA INVESTIGACIÓN: serie de casos consecutivos anidados en una cohorte RESULTADOS: se han incluido 196 pacientes con un promedio de edad de 46,5 años (DE± 14,735 años) distribuidos por género en 88 pacientes del género femenino (44,9%) y 108 del género masculino (55,1%). El promedio de leucocitosis fue de 10.000 x mm3 con desvío izquierdo (80% de segmentados promedio). La prevalencia de cultivos positivos durante la CA fue de 64 pacientes (32,65%). El germen más cultivado fue la E. Coli en 28 pacientes con (43,75 %). En la sensibilidad del antibiograma, amoxicilina y Acido clavulánico presenta 53,12% de resistencia cuando están asociadas y 25,56% cuando se usa amoxicilina sola. La amikacina, ceftriaxona, cefepime, imipemen, cloranfenicol, ciprofloxacina, cotrimoxazol y gentamicina tienen sensibilidad superior al 50%. En las formas edematosas el cultivo fue de 19,7%, hidrops vesicular 31,25%, en piocolecisto el porcentaje de cultivos positivos fue de 50% y en abscesos retrovesiculares fue de 79,16%. CONCLUSIONES: la prevalencia de cultivo positivo en CA es de 32,65% con la E. Coli como germen más frecuente. La elección del antibiótico debe estar basada en el conocimiento de la microbiología del Hospital y de la sensibilidad determinada por los cultivos y antibiograma

AIM: to determine the microbiology and prevalence of positive bile culture un acute Cholecystitis. RESEARCH METODOLOGY: Consecutive case series nested in a cohort RESULTS: 196 patients with a mean age of 46,5 años (DE± 14,735 años) were included, distributed by gender 88 female patients (44,9%) and 108 male patients (55,1%). The mean leukocytosis was 10.000 x mm3 with 80% of neutrophils. The prevalence of positive bile culture in AC was in 64 patients (32,65%). The most cultivated germ was E. Coli in 28 patients (43,75 %). In the sensitivity of the antibiogram amoxilin with clavulanic acid shows 53,12% of resistence and when is used amoxicillin alone is 25,56%. Amikacin, ceftriaxon, cefepim, imipemen, chloranphenicol, ciprofloxacin, cotrimoxazole and gentamicin have sensitivity greater to 50%. In edematous AC the positive culture was 19,7%, hydrops gallblader 31,25%, in piocolecyst 50% and in retro gallbalder abscess was 79,16%. CONCLUSIONS: the prevalence positive bile culture was 32,65% with E. Coli as the most frequent germ. The choice of antibiotic should be based on the knowledge of the hospital´s microbiology and the sensitivity determinated by cultures and antibiogram

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

Duración de la antibioticoterapia en pacientes con colecistitis aguda manejados con colecistostomía. ¿Afecta los desenlaces clínicos? / Duration of antibiotic therapy in patients with acute cholecystitis managed with cholecystostomy. Does it affect clinical outcomes?

Introducción. En pacientes con diagnóstico de colecistitis aguda tratados con colecistostomía, el tiempo óptimo de duración de la terapia antibiótica es desconocido. El objetivo de este trabajo fue comparar los resultados clínicos en pacientes con diagnóstico de colecistitis aguda manejados inicialmente con colecistostomía y que recibieron cursos cortos de antibióticos (7 días o menos) versus cursos largos (más de 7 días). Métodos. Se llevó a cabo un estudio de cohorte observacional, retrospectivo, que incluyó pacientes con diagnóstico de colecistitis aguda manejados con colecistostomía, que recibieron tratamiento antibiótico. Se hizo un análisis univariado y de regresión logística para evaluar la asociación de variables clínicas con la duración del tratamiento antibiótico. El desenlace primario por evaluar fue la mortalidad a 30 días. Resultados. Se incluyeron 72 pacientes. El 25 % (n=18) recibieron terapia antibiótica por 7 días o menos y el 75 % (n=54) recibieron más de 7 días. No hubo diferencias significativas en la mortalidad a 30 días entre los dos grupos ni en las demás variables estudiadas. La duración de la antibioticoterapia no influyó en la mortalidad a 30 días (OR 0,956; IC95% 0,797 - 1,146). Conclusión. No hay diferencias significativas en los desenlaces clínicos de los pacientes con colecistitis aguda que son sometidos a colecistostomía y que reciben cursos cortos de antibióticos en comparación con cursos largos

Introduction.In patients with acute cholecystitis who receive treatment with cholecystostomy, the optimal duration of antibiotic therapy is unknown. The objective of this study is to compare short courses of antibiotics (7 days or less) with long courses (more than 7 days) in this population. Methods. We performed a retrospective observational cohort study which included patients diagnosed with acute cholecystitis, who received antibiotic therapy and were taken to cholecystostomy. Univariate analysis and logistic regression were performed to evaluate the association between clinical variables and the duration. The main outcome evaluated was 30-day mortality. Results. Seventy-two patients were included, 25% (n=18) were given 7 or fewer days of antibiotics while 75% (n=54) were given them for more than 7 days. Demographic data between both groups were similar (age, severity of cholecystitis, comorbidities). There were no significant differences in 30-day mortality between both groups. Antibiotic duration did not influence mortality at 30 days (OR 0.956, 95% CI 0.797 - 1.146). Conclusion. There are no significant differences in the clinical outcomes of patients with acute cholecystitis who undergo cholecystostomy and receive short courses of antibiotics compared to long courses

Acute cholecystitis in high-risk patients. surgical, radiological, or endoscopic treatment? brazilian college of digestive surgery position paper / Colecistite aguda em pacientes de alto risco. tratamento cirúrgico, radiológico ou endoscópico? posicionamento do colégio brasileiro de cirurgia digestiva

ABSTRACT Acute cholecystitis (AC) is an acute inflammatory process of the gallbladder that may be associated with potentially severe complications, such as empyema, gangrene, perforation of the gallbladder, and sepsis. The gold standard treatment for AC is laparoscopic cholecystectomy. However, for a small group of AC patients, the risk of laparoscopic cholecystectomy can be very high, mainly in the elderly with associated severe diseases. In these critically ill patients, percutaneous cholecystostomy or endoscopic ultrasound gallbladder drainage may be a temporary therapeutic option, a bridge to cholecystectomy. The objective of this Brazilian College of Digestive Surgery Position Paper is to present new advances in AC treatment in high-risk surgical patients to help surgeons, endoscopists, and physicians select the best treatment for their patients. The effectiveness, safety, advantages, disadvantages, and outcomes of each procedure are discussed. The main conclusions are: a) AC patients with elevated surgical risk must be preferably treated in tertiary hospitals where surgical, radiological, and endoscopic expertise and resources are available; b) The optimal treatment modality for high-surgical-risk patients should be individualized based on clinical conditions and available expertise; c) Laparoscopic cholecystectomy remains an excellent option of treatment, mainly in hospitals in which percutaneous or endoscopic gallbladder drainage is not available; d) Percutaneous cholecystostomy and endoscopic gallbladder drainage should be performed only in well-equipped hospitals with experienced interventional radiologist and/or endoscopist; e) Cholecystostomy catheter should be removed after resolution of AC. However, in patients who have no clinical condition to undergo cholecystectomy, the catheter may be maintained for a prolonged period or even definitively; f) If the cholecystostomy catheter is maintained for a long period of time several complications may occur, such as bleeding, bile leakage, obstruction, pain at the insertion site, accidental removal of the catheter, and recurrent AC; g) The ideal waiting time between cholecystostomy and cholecystectomy has not yet been established and ranges from immediately after clinical improvement to months. h) Long waiting periods between cholecystostomy and cholecystectomy may be associated with new episodes of acute cholecystitis, multiple hospital readmissions, and increased costs. Finally, when selecting the best treatment option other aspects should also be considered, such as costs, procedures available at the medical center, and the patient's desire. The patient and his family should be fully informed about all treatment options, so they can help making the final decision.

RESUMO A colecistite aguda (CA) é um processo inflamatório agudo da vesícula biliar que pode estar associado a complicações potencialmente graves, como empiema, gangrena, perfuração da vesícula biliar e sepse. O tratamento padrão para a CA é a colecistectomia laparoscópica. No entanto, para um pequeno grupo de pacientes com CA, o risco de colecistectomia laparoscópica pode ser muito alto, principalmente em idosos com doenças graves associadas. Nestes pacientes críticos, a colecistectomia percutânea ou a drenagem endoscópica da vesícula biliar guiada por ultrassom podem ser uma opção terapêutica temporária, como ponte para a colecistectomia. O objetivo deste artigo de posicionamento do Colégio Brasileiro de Cirurgia Digestiva é apresentar novos avanços no tratamento da CA em pacientes cirúrgicos de alto risco, para auxiliar cirurgiões, endoscopistas e clínicos a selecionar o melhor tratamento para os seus pacientes. A eficácia, segurança, vantagens, desvantagens e resultados de cada procedimento são discutidos. As principais conclusões são: a) Pacientes com CA e risco cirúrgico elevado devem ser tratados preferencialmente em hospitais terciários onde a experiência e os recursos cirúrgicos, radiológicos e endoscópicos estão disponíveis. b) A modalidade de tratamento ideal para pacientes com elevado risco cirúrgico, deve ser individualizada, com base nas condições clínicas e na experiência disponível. c) A colecistectomia laparoscópica continua sendo uma excelente opção de tratamento, principalmente em hospitais em que a drenagem da vesícula biliar percutânea ou endoscópica não está disponível. d) A colecistostomia percutânea e a drenagem endoscópica da vesícula biliar devem ser realizadas apenas em hospitais bem equipados e com radiologista intervencionista e/ou endoscopista experientes. e) O cateter de colecistostomia deve ser removido após a resolução da CA. No entanto, em pacientes que não têm condição clínica para realizar colecistectomia, o cateter pode ser mantido por um período prolongado ou mesmo definitivamente. f) Se o cateter de colecistostomia for mantido por longo período de tempo podem ocorrer várias complicações, como sangramento, fístula biliar, obstrução, dor no local de inserção, remoção acidental do cateter e CA recorrente. g) O tempo de espera ideal entre a colecistostomia e a colecistectomia ainda não foi estabelecido, e vai desde imediatamente após a melhoria clínica, até meses após. h) Longos períodos de espera entre colecistostomia e colecistectomia podem estar associados a novos episódios de CA, múltiplas readmissões hospitalares e aumento dos custos. Finalmente, ao selecionar a melhor opção de tratamento, outros aspectos também devem ser considerados, como custos, disponibilidade dos procedimentos no centro médico e o desejo do paciente. O paciente e sua família devem ser completamente informados sobre todas as opções de tratamento, para que possam ajudar a tomar a decisão final.

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.

When to remove the drainage catheter in patients with percutaneous cholecystostomy?

SUMMARY OBJECTIVE: The treatment for patients with acute calculous cholecystitis who have high surgical risk with percutaneous cholecystostomy instead of surgery is an appropriate alternative choice. The aim of this study was to examine the promising percutaneous cholecystostomy intervention to share our experiences about the duration of catheter that has yet to be determined. METHODS: A total of 163 patients diagnosed with acute calculous cholecystitis and treated with percutaneous cholecystostomy between January 2011 and July 2020 were reviewed retrospectively. The Tokyo Guidelines 2018 were used to diagnose and grade patients with acute cholecystitis. RESULTS: The mean age was 71.81±12.81 years. According to the Tokyo grading, 143 patients had grade 2 and 20 patients had grade 3 disease. The mean duration of catheter was 39.12±37 (1-270) days. Minimal bile leakage into the peritoneum was noted in 3 (1.8%) patients during the procedure. The rate of complications during follow-up of the patients who underwent percutaneous cholecystostomy was 6.9% (n=11), and the most common complication was catheter dislocation. Cholecystectomy was performed in 33.1% (n=54) of the patients at follow-up. Post-cholecystectomy complication rate was 12.9%. At the follow-up, the rate of recurrent acute cholecystitis episodes was 5.5%, while the mortality rate was 1.8%. The length of follow-up was five years. CONCLUSIONS: The rate of recurrence was significantly higher among the patients with catheter for <21 days. We recommend that the duration of catheter should be minimum 21 days in patients undergoing percutaneous cholecystostomy.

Current status and progress of endoscopic drainage for acute cholecystitis / 中华消化外科杂志

The fundamental treatment for acute cholecystitis is surgical cholecystectomy, especially laparoscopic cholecystectomy. Some high-risk surgical patients need gallbladder drainage. The traditional drainage method is percutaneous transhepatic gallbladder drainage. However, in recent years, two endoscopic approaches, including endoscopic transpapillary gallbladder drainage and endoscopic ultrasound-guided gallbladder drainage, have developed rapidly and have advantages in long-term outcomes. In this article, the authors discuss the historical development, technical characteristics, comparison between methods , adverse events and long-term outcomes of the two endoscopic drainage methods through literature review.

Severidad de la colecistitis aguda en tiempos de COVID-19: ¿mito o realidad? / Severity of acute cholecystitis in times of COVID-19: myth or reality?

Introducción. La colecistitis aguda es una de las causas más frecuentes de ingresos hospitalarios y la colecistectomía laparoscópica es el estándar de oro para su manejo. Dentro de los efectos de la pandemia por COVID-19 se ha percibido un aumento en la severidad de presentación en estos pacientes. Este estudio tuvo como objetivo comparar la presentación clínica y quirúrgica de la colecistitis aguda antes y durante la pandemia por COVID-19. Métodos. Estudio retrospectivo de una cohorte con pacientes llevados a colecistectomía laparoscópica por colecistitis aguda entre 2019 y 2020. Se realizó un análisis bivariado y de Kaplan Meier con el tiempo transcurrido entre inicio de síntomas y el ingreso al hospital, y entre el ingreso del hospital y la realización de la cirugía. Resultados. Fueron llevados a colecistectomía laparoscópica por colecistitis aguda un total de 302 pacientes. El tiempo de evolución de los síntomas hasta el ingreso fue de 83,3 horas (IC95%: 70,95 ­ 96,70) antes de la pandemia y 104,75 horas (IC95%: 87,26 ­ 122,24) durante la pandemia. El tiempo entre el ingreso al hospital y el procedimiento quirúrgico fue significativamente menor en el período de pandemia (70,93 vs. 42,29; p<0,001). El porcentaje con mayor severidad (Parkland 5) fue igual antes y durante la pandemia (29 %). Conclusión. Se reporta una severidad clínica y quirúrgica similar antes y durante la pandemia por COVID-19, probablemente secundario a los resultados de un tiempo de entrada al quirófano significativamente menor durante la pandemia, debido a una mayor disponibilidad de quirófanos para las patologías quirúrgicas urgentes.

Introduction. Acute cholecystitis is one of the most frequent causes of hospital admissions in the adult population and laparoscopic cholecystectomy is considered the gold standard for its management. Within the effects of the COVID-19 pandemic, an increase in the severity of presentation has been perceived in these patients. This study aims to compare the clinical and surgical presentation based on the different severity scales of acute cholecystitis before and during the COVID-19 pandemic. Methods. A retrospective cohort study was performed with patients undergoing laparoscopic cholecystectomy for acute cholecystitis between 2019 and 2020. A bivariate and Kaplan Meier analysis was performed with the time elapsed between onset of symptoms and admission to hospital, and between admission to hospital and performance of surgery. Results. A total of 302 patients underwent laparoscopic cholecystectomy for acute cholecystitis. The time of evolution of symptoms until admission was 83.3 hours (95% CI: 70.95 - 96.70) vs. of 104.75 hours (95% CI: 87.26 - 122.24) before and during the pandemic, respectively. The time between admission to the hospital and the surgical procedure was significantly shorter in the current pandemic period (70.93 vs. 42.29; p<0.001). The patients with greater severity (Parkland 5) was the same before and during pandemic (29%). Conclusion. Similar clinical and surgical severity is reported before and during the COVID 19 pandemic, probably secondary to the results of a significantly shorter entry time to the operating room during the pandemic, due to a greater availability of operating rooms for urgent surgical pathologies.

Cirugía de emergencia por colecistitis aguda debido a fístula colecistocolónica / Emergency surgery for acute cholecystitis caused by cholecystocolonic fistula

RESUMEN La fístula colecistocolónica (FCC) es una complicación poco común de la colelitiasis. A menudo son asintomáticas, de difícil diagnóstico preoperatorio a pesar del apoyo radiológico, y se descubren de manera incidental perioperatoriamente. Presentamos el caso de una mujer con un cuadro de colecistitis aguda, la cual fue intervenida por laparoscopía, y se evidenció una FCC, la cual fue resuelta mediante conversión a cirugía abierta. La FCC puede complicarse y simular cuadros abdominales agudos. Se debe tener en cuenta en adultos mayores, con historia de colelitiasis, y vesículas escleroatróficas con adherencias. En la literatura se han descrito muy pocos casos, y ninguno en nuestro medio. Presentamos un caso de FCC que ingresó como una colecistitis aguda, y su diagnóstico y tratamiento fueron durante su cirugía.

ABSTRACT Cholecystocolonic fistula (CCF) is a rare complication of cholelithiasis. They are often asymptomatic, difficult to diagnose preoperatively, it despite radiological support, and they are discovered incidentally perioperatively. We present the case of a woman with acute cholecystitis, who was operated by laparoscopy, and a CCF was evidenced, it was resolved by conversion to open surgery. FCC can be complicated and simulate acute abdominal symptoms. It should be taken into account in older adults with a history of cholelithiasis and scleroatrophic vesicles with adhesions. Very few cases have been described in the literature, and none in our country. We present a case of FCC that was admitted as acute cholecystitis, and the diagnosis and treatment of it were during her surgery.

Niveles séricos de proteína C reactiva como marcador de gravedad de colecistitis aguda litiásica: serie de casos prospectiva / Serum levels of C-reactive protein as a marker of gravity of acute cholecystitis: prospective series of cases

La colecistitis aguda (CA) es la principal complicación de la litiasis vesicular. Existe evidencia que respalda el hecho que la proteína C reactiva (PCR) se elevaría en distintos niveles según gravedad de la CA. El objetivo de este estudio fue determinar asociación entre valores de PCR y estadios clínicos de gravedad de CA. Serie de casos consecutivos de adultos con CA diagnosticada por clínica, ultrasonografía y criterios de Tokio; tratados en un centro de salud terciario de La Paz, Bolivia (diciembre 2019 y enero 2020). La variable resultado fue niveles de PCR. Otras de interés fueron variables biodemográficas. Se aplicó estadística descriptiva (cálculo de porcentajes, de medidas de tendencia central y de dispersión); y posteriormente, se aplicaron estadísticas analíticas para estudiar asociación entre variables (test exacto de Fisher para variables categóricas y t de student para variables continuas). Se estudiaron 44 pacientes (33 con CA leve y 10 con CA moderada), con edad promedio de 51,7±15,3 años; 59,1 % de sexo femenino. El peso, estatura e IMC promedio fueron 69,6±10,3 kg; 1,6±0,1 m; y 27,0±3,1 kg/m2 respectivamente. Las cifras promedio de PCR fueron 9,0±11,6 y 29,5±20,2 en los subgrupos CA leve y moderada respectivamente (p=0,001). Los valores de PCR se asociaron a dos estadios de gravedad clínica de CA.

Serum levels of C-reactive protein as a marker of gravity of acute cholecystitis. Prospective series of cases. Acute cholecystitis (AC) is the main complication of cholelithiasis. There is evidence supporting the fact that C-reactive protein (CRP) would rise at different levels depending on severity of AC. The objective of this study was to determine the association between CRP values and clinical stages of CA severity. Series of consecutive cases of adults with AC diagnosed by clinical, ultrasound and Tokyo criteria; treated at a tertiary health center in La Paz, Bolivia between December 2019 and January 2020. The result variable was CRP determination. Others of interest were biodemographic variables. Descriptive statistics (calculation of percentages, measures of central tendency and dispersion) were applied; later, analytical statistics were applied to study the association between variables (Fisher's exact test for categorical variables and Student's t test for continuous variables). Also, 44 patients were treated (33 with mild AC and 10 with moderate AC), with an average age of 51.7±15.3 years; 59.1 % female. Average weight, height and BMI were 69.6±10.3 kg; 1.59±0.1 m; and 27±3.1 kg/m2 respectively. The mean CRP values were 9.0±11.6 and 29.5±20.2 in the mild and moderate AC subgroups respectively (p=0.001). CRP values were associated with two stages of clinical severity of Acute Cholecystitis.

A comparative study of interval cholecystectomy and early cholecystectomy in acute cholecystitis

Background: In the whole world including India, the incidence of acute cholecystitis is increasing day by day. Gall stones are the most common cause of acute cholecystitis in 90-95% of the cases. The management of acute cholecystitis was conservative earlier but now there are studies recommending early surgery as the treatment of choice.Methods: Our study was conducted on 60 patients divided into two groups of 30 each to compare the results of early surgery with the delayed surgery.Results: The overall post-operative complication rate was same in both the groups but there was significant difference in the total hospital stay and total cost of the therapy in both the groups. The average total hospital stay in early group was 6.50±4.44 days and in delayed group was 10.80±5.55 days without including the number of days in non-operating admission.Conclusions: So, early cholecystectomy was found to be more economical with less total hospital stay and less total cost of the therapy than interval cholecystectomy in acute cholecystitis.

Outcome of early laparoscopic cholecystectomy versus delayed laparoscopic cholecystectomy for patients with acute cholecystitis

Background: This prospective randomized study was undertaken to to assess the outcomes of early versus delayed cholecystectomy for patient’s acute cholecystitis.Methods: 70 patients with acute cholecystitis were prospectively randomized to either an early laparoscopic cholecystectomy (n=35) or a delayed laparoscopic cholecystectomy group (n=35). The mean operative time, conversion rate, total hospital stay, intra-operative and post-operative complications, average hospital cost were evaluated between the two groups.Results: A total of 70 patients were enrolled, 35 patients in each group. There was no significant difference in the conversion rates (early, 8.57% vs delayed, 5.71%) and postoperative complications (early, 25% vs delayed, 20%). At the cost of an increased operating time (early, 81 minutes vs delayed, 78 minutes) and blood loss (early, 180.33ml vs delayed, 108.00 ml), early laparoscopic cholecytectomy significantly shortened the total hospital stay (early, 1.5 days vs. delayed, 7.95 days) and  average hospital cost (early 9240 INR vs delayed, 12251 INR).Conclusions: The safety and efficacy of early and delayed laparoscopic cholecystectomy for acute cholecystitis were comparable in terms of morality, morbidity and conversion rate. However early laparoscopic cholecystectomy allows significantly shorter  total hospital stay and reduction in days away from work at the cost of  longer operating time and blood loss and offers definitive treatment at initial admission. Moreover it avoids repeated admissions for recurrent symptoms has both medical as well as socioeconomic benefits and should be the preferred approach for patients managed by surgeons with adequate experience in laparoscopic cholecystectomy.

Comparison of the role of ultrasound guided transhepatic aspiration of gallbladder versus conservative management of acute calculous cholecystitis

Background: Gall stone disease remains one of the most common medical problem leading to surgical intervention. Cholecystitis accounts for 3-10% of abdominal pain worldwide. Acute cholecystitis is the most common complication of cholelithiasis accounting for 14 to 30% of cholecystectomies performed in many countries. Symptoms in cholecystitis are due to impaction of stone and subsequent distention of gallbladder with inflammation. Study is aimed to clarify the role of ultrasound guided transhepatic gallbladder aspiration in the early management of acute calculous cholecystitis.Methods: The study was conducted in total of 40 patients presenting with acute cholecystitis. 20 patients underwent ultrasound guided transhepatic aspiration of gallbladder with antibiotics (group A) and 20 patients were given antibiotics only (group B). Data were collected before intervention and post intervention duration of stay, pain according to visual analog scale, leucocytosis and fever were recorded for analysis. No complications were related to aspiration procedure.Results: Both groups were comparable. Group A patients had better pain relief (p=0.0001 day on 2 and p=0.004 on day 3 post aspiration), percentage reduction of leucocyte count (p=0.041 on day 3) and duration of hospital stay (p=0.004) which were statistically significant.Conclusions: Ultrasound guided transhepatic aspiration of gall bladder with antibiotics in acute cholecystitis results in better pain profile, faster reduction in leucocyte count and shorter duration of hospital stay when compared to antibiotics alone.

Colecistectomía subtotal: una alternativa en el manejo de la colecistectomía difícil / Subtotal cholecystectomy: an alternative in the management of difficult cholecystectomy

Introducción. Alrededor de un 10 % de las laparoscopias se convierten a cirugía abierta por dificultades en obtener una visión crítica durante la colecistectomía en colecistitis severas. La colecistectomía subtotal es una posibilidad terapéutica disponible, que disminuye la tasa de conversión en cirugía laparoscópica y mantiene bajas tasas de morbilidad y mortalidad. Métodos. Estudio descriptivo, retrospectivo, de pacientes sometidos a colecistectomía subtotal en la Clínica CES (Medellín, Colombia) entre enero y diciembre de 2015. Se identificaron variables demográficas, detalles de la cirugía, morbilidad y mortalidad. Resultados. De un total de 710 colecistectomías en dicho periodo, a 17 (2,4 %) se les realizó colecistectomía sub-total. Quince (88 %) de ellas fueron por laparoscopia y dos requirieron conversión. La distribución en cuanto a sexo fue similar (10 mujeres / 7 hombres) y la edad promedio fue de 51 años. El tiempo quirúrgico promedio fue de 119 minutos. En 14 (82 %) pacientes se dejó drenaje subhepático. Dos pacientes presentaron fístula biliar y un paciente reingresó por un hematoma; no se presentaron otras complicaciones. La estancia hospitalaria promedio fue de 5,2 días. Discusión. La colecistectomía subtotal es una alternativa en pacientes con colecistectomía difícil y en nuestra experiencia presenta una alta tasa de éxito

Introduction. About 10% of laparoscopies are converted to open surgery due to difficulties in obtaining critical vision during cholecystectomy in severe cholecystitis. Subtotal cholecystectomy is an available therapeutic possibi-lity, which decreases the conversion rate in laparoscopic surgery and maintains low morbidity and mortality rates.Methods. Descriptive, retrospective study of patients who underwent subtotal cholecystectomy between January and December 2015. Demographic variables, details of surgery, morbidity and mortality were identified.Results. Of a total of 710 cholecystectomies in that period, 17 (2.4%) underwent subtotal cholecystectomy. Fifteen (88%) of them were by laparoscopy and two required conversion. The gender distribution was similar (10 women/7 men) and the average age was 51 years. The average surgical time was 119 minutes. Subhepatic drainage was left in 14 (82%) patients. Two patients had a biliary fistula and one patient was readmitted for a hematoma; there were no other complications. The average hospital stay was 5.2 days.Discussion. Subtotal cholecystectomy is an alternative in patients with difficult cholecystectomy and in our experience, it has a high success rate

¿Es más difícil la colecistectomía laparoscópica después de una colangiopancreatografía retrógrada endoscópica? Experiencia en un hospital de tercer nivel / Is the laparoscopic cholecystectomy more difficult after endoscopic retrograde cholangiopancreatography? Experience in a third level hospital

Introducción. La colecistectomía laparoscópica es el tratamiento estándar para la colecistitis aguda. En pacientes con coledocolitiasis, la colangiopancreatografía retrógrada endoscópica es el tratamiento de elección. Se ha reportado que, después de este procedimiento endoscópico, la colecistectomía laparoscópica es más difícil y son mayores las tasas de conversión, hemorragia y tiempo operatorio. El objetivo de este estudio fue determinar si en nuestro medio las colecistectomías laparoscópicas posteriores a este procedimiento endoscópico presentan más complicaciones posquirúrgicas y mayor dificultad técnica. Métodos. Estudio de cohorte prospectivo, en el que se comparó un grupo de pacientes sometidos a colecistectomía laparoscópica previa colangiopancreatografía retrógrada endoscópica, contra un grupo homogéneo de pacientes sin colangiografía previa, para evaluar la dificultad en la colecistectomía laparoscópica, la conversión, la reintervención y las complicaciones. Resultados. El 45,4 % de las cirugías fueron difíciles.No hay relación entre la realización previa de colangio-pancreatografía retrógrada endoscópica y la dificultad de la colecistectomía laparoscópica. Con el modelo de regresión logística, se encontraron como factores predictores para una cirugía difícil, la edad, el sexo masculino, la cirugía abdominal previa, la colecistitis aguda y la mayor gravedad de la colecistitis aguda. Conclusión. La colangiopancreatografía retrógrada endoscópica en nuestro medio no constituye un factor de riesgo para dificultad en la colecistectomía laparoscópica. Debe prestarse especial cuidado al sexo masculino, la gravedad de la colecistitis aguda, los antecedentes de cirugía abdominal y la presencia de comorbilidades a la hora de planear una colecistectomía laparoscópica, tomando precauciones adicionales en estos casos para prevenir complicaciones

Introduction: Laparoscopic cholecystectomy is the standard treatment for acute cholecystitis. In patients who also have choledocholithiasis, endoscopic retrograde cholangiopancreatography is the treatment of choice. In some studies, it has been reported that, after this endoscopic examination, laparoscopic cholecystectomy is more difficult, and conversion rates, bleeding and operative time are higher. The objective of this study was to determine whether laparoscopic cholecystectomies after this endoscopic procedure present more postoperative complications and greater technical difficulty in our setting.Methods: Prospective cohort study, in which a group of patients who underwent laparoscopic cholecystectomy prior endoscopic retrograde cholangiopancreatography was compared against a homogeneous group of patients without previous cholangiography, to assess the difficulty of laparoscopic cholecystectomy, conversion, reoperation and complications.Results: 45.4 % of the surgeries were difficult. There is no relationship between the previous performance of ERCP and the difficulty of laparoscopic cholecystectomy. With the logistic regression model, age, male gender, previous abdominal surgery, acute cholecystitis and greater degree of severity of acute cholecystitis were found as predictive factors for difficult surgery.Conclusion: ERCP in our setting is not a risk factor for difficult laparoscopic cholecystectomy. Special care should be taken to the male gender, the severity of acute cholecystitis, the history of abdominal surgery and the presence of comorbidities when planning a laparoscopic cholecystectomy, taking additional precautions in these cases to prevent complications

Laparoscopic Cholecystectomy In Acute Cholecystitis: A Prospective Study

Acute cholecystitis (AC) is a potentially life-threatening condition. AC was initially considered to be a relative contraindication for laparoscopic 1 cholecystectomy (LC), but with increase in general expertise, early LC was recommended in selected patients . Aprospective study of LC in grade 1 and 2 AC patients with mild to moderate inflammatory changes in the gallbladder and no significant organ dysfunction, was performed during October 2016 to July 2019. A total of 78 patients, out of 408 cholecystectomies performed during this period, were included in this study. Criteria for diagnosing AC was, recent onset of pain in right hypochondrium, fever, leucocytosis, pericholecystic fluid collections, subserosal oedema on ultrasound, pyocele and other pathological evidence of AC. Patients presented and operated within 4 days of onset of symptoms showed better results as compared to those who could be operated after 4 days and within 14 days. Five patients required conversion to open cholecystectomy because of complex adhesions in 2, critical view of safety was unachievable in 2 and in 1 for troublesome bleeding.

Complicaciones biliares en pacientes con diagnóstico previo de litiasis vesicular sintomática: Comparación entre un hospital público y otro privado del Gran Buenos Aires / Biliary complications in patients with previous diagnosis of symptomatic gallstones: Comparison between a public and a private hospital in Greater Buenos Aires

Antecedentes: la demora en el tratamiento de la litiasis vesicular sintomática (LVS) aumenta el riesgo de complicaciones biliares. Se plantea la hipótesis de que existen diferencias en el tratamiento de la LVS entre el sector público y el de obras sociales del Gran Buenos Aires (GBA). Objetivo: comparar la proporción de pacientes con litiasis biliar complicada (LBC) que presentaban diagnóstico previo de LVS, y evaluar la historia previa de la LBC según la presencia de síntomas y la relación con el sistema de salud. Material y métodos: estudio de corte transversal comparativo entre un hospital público (HPu) y otro privado (HPr) del GBA. Se analizó la historia clínica y se realizó una encuesta a pacientes colecistectomizados por LBC (colecistitis aguda, pancreatitis aguda y coledocolitiasis). Resultados: se incluyeron 105 pacientes del HPu y 136 del HPr. Las características basales difirieron en la edad, nivel educativo, distancia domicilio-hospital y ASA. El diagnóstico previo de LVS fue más frecuente en el HPu (60% vs. 39,7%; p = 0,02), diferencia que se mantuvo luego del ajuste multivariable (OR 2,14; IC 95%: 1,1 a 4,1; p = 0,02). Los pacientes del HPu mostraron una mayor frecuencia de dolores abdominales, tiempo desde el diagnóstico, número de consultas de urgencia luego del diagnóstico y mayor tiempo en lista de espera. Conclusiones: ell HPu mostró mayor pérdida de oportunidad quirúrgica de la litiasis vesicular en un estadio previo no complicado. Las causas podrían ser multifactoriales, pero se necesitan más estudios para corroborar esta hipótesis.

Background: Delays in the treatment of symptomatic cholelithiasis (SCL) increases the risk of biliary complications. There may be differences in the treatment of SCL between the public sector and the social security in the Greater Buenos Aires (GBA). Objectives: The aim of this study was to compare the proportion of patients with complicated gallstone disease (CGD) with previous diagnosis of SCL and to evaluate the history of CGD according to the presence of symptoms and its relation with the health care system. Material and methods: We conducted a cross-sectional study comparing a public hospital (PH) versus a private center (PrH) in the GBA. The clinical records were analyzed and patients with a history of cholecystectomy due to CGD (acute cholecystitis, acute pancreatitis and acute choledocholithiasis) were surveyed. Results: A total of 105 PH patients and 136 PrH patients were included. The baseline characteristics differed in terms of age, educational level, distance from home to hospital and ASA physical status classification. The previous diagnosis of SCL was more common in the PH (60% vs. 39.7%; p = 0.02) and this difference persisted after multivariate adjustment (OR 2.14; 95% CI, 1.1-4.1; p = 0.02). The PH presented more patients with abdominal pain and more visits to the emergency department (ED) after the diagnosis; time after the diagnosis was greater and these patients spent more time on the waiting list. Conclusions: The PH showed greater loss of surgical opportunity of uncomplicated cholelithiasis. This may be due to multiple factors, but further studies are necessary to confirm this hypothesis.
