A novel comparison of erector spinae plane block and paravertebral block in laparoscopic cholecystectomy

SUMMARY OBJECTIVE: Erector spinae plane block is an updated method than paravertebral block, possessing a lower risk of complications. This study aimed to compare erector spinae plane and paravertebral blocks to safely reach the most efficacious analgesia procedure in laparoscopic cholecystectomy cases. METHODS: The study included 90 cases, aged 18-70 years, classified as American Society of Anesthesiologists I-II, who underwent an laparoscopic cholecystectomy procedure. They were randomly separated into three groups, namely, Control, erector spinae plane, and paravertebral block. No block procedure was applied to Control, and a patient-controlled analgesia device was prepared containing tramadol at a 10 mg bolus dose and a 10-min locked period. The pain scores were recorded with a visual analog scale for 24 h postoperatively. RESULTS: The visual analog scale values at 1, 5, 10, 20, and 60 min at rest and 60 min coughing were found to be significantly higher in Control than in paravertebral block. A significant difference was revealed between Control vs. paravertebral block and paravertebral block vs. erector spinae plane in terms of total tramadol consumption (p=0.006). Total tramadol consumption in the first postoperative 24 h was significantly reduced in the paravertebral block compared with the Control and erector spinae plane groups. CONCLUSION: Sonography-guided-paravertebral block provides sufficient postoperative analgesia in laparoscopic cholecystectomy surgery. Erector spinae plane seems to attenuate total tramadol consumption.

Modified thoracoabdominal nerves block through perichondrial approach for laparoscopic cholecystectomy

SUMMARY OBJECTIVE: A new block, namely, modified thoracoabdominal nerves block through perichondrial approach, is administered below the costal cartilage. We sought to compare the analgesic efficacy of the modified thoracoabdominal nerves block through perichondrial approach block with local anesthetic infiltration at the port sites in an adult population who underwent laparoscopic cholecystectomy. METHODS: Patients who will undergo laparoscopic cholecystectomy were randomized to receive bilateral ultrasound-guided modified thoracoabdominal nerves block through perichondrial approach blocks or local anesthetic infiltration at the port insertion sites. The primary outcome was the total amount of tramadol used in the first 12 h postoperatively. The secondary outcomes were total IV tramadol consumption for the first postoperative 24 h and visual analog scale scores. RESULTS: The modified thoracoabdominal nerves block through perichondrial approach group had significantly less tramadol use in the first 12 h postoperatively (p<0.001). The modified thoracoabdominal nerves block through perichondrial approach group's visual analog scale scores at rest (static) and with movement (dynamic) were significantly lower compared with the port infiltration group (p<0.05). CONCLUSION: Patients who received modified thoracoabdominal nerves block through perichondrial approach block had significantly less analgesic consumption and better pain scores than those who received port-site injections after laparoscopic cholecystectomy.

The effects of positive end-expiratory pressure (PEEP) application on optic nerve sheath diameter in patients undergoing laparoscopic cholecystectomy: a randomized trial

Abstract Background: Positive end-expiratory pressure (PEEP) can overcome respiratory changes that occur during pneumoperitoneum application in laparoscopic procedures, but it can also increase intracranial pressure. We investigated PEEP vs. no PEEP application on ultrasound measurement of optic nerve sheath diameter (indirect measure of increased intracranial pressure) in laparoscopic cholecystectomy. Methods: Eighty ASA I-II patients aged between 18 and 60 years scheduled for elective laparoscopic cholecystectomy were included. The study was registered in the Australian New Zealand Clinical Trials (ACTRN12618000771257). Patients were randomly divided into either Group C (control, PEEP not applied), or Group P (PEEP applied at 10 cmH20). Optic nerve sheath diameter, hemodynamic, and respiratory parameters were recorded at six different time points. Ocular ultrasonography was used to measure optic nerve sheath diameter. Results: Peak pressure (PPeak) values were significantly higher in Group P after application of PEEP (p = 0.012). Mean respiratory rate was higher in Group C at all time points after application of pneumoperitoneum (p < 0.05). The mean values of optic nerve sheath diameters measured at all time points were similar between the groups (p > 0.05). The pulmonary dynamic compliance value was significantly higher in group P as long as PEEP was applied (p = 0.001). Conclusions: During laparoscopic cholecystectomy, application of 10 cmH2O PEEP did not induce a significant change in optic nerve sheath diameter (indirect indicator of intracranial pressure) compared to no PEEP application. It would appear that PEEP can be used safely to correct

Resumen: Introducción: contar con una analgesia efectiva en el postoperatorio es fundamental para evitar complicaciones asociadas a dolor, en pacientes sometidos a colecistectomía laparoscópica. Objetivos: evaluar la efectividad de la lidocaína en infusión transoperatoria para el control de dolor postoperatorio en pacientes sometidos a colecistectomía laparoscópica. Material y métodos: se realizó un estudio experimental, aleatorizado, ciego simple, en pacientes sometidos a colecistectomía laparoscópica en el Hospital General Regional No. 1 en Obregón. Se dividieron en dos grupos de forma aleatoria, al grupo L se le aplicó lidocaína 1.5 mg/k en infusión, al grupo P se le aplicó placebo. Se realizó un análisis estadístico en SPSS v. 22 y se consideró significativa una p < 0.05. Resultados: se observó un adecuado manejo del dolor en los pacientes del grupo L a su ingreso a la Unidad de Recuperación Postanestésica (URPA) (p = 0.002), menor consumo de fentanyl transoperatorio sin diferencia estadística contra placebo (p = 0.086), menor uso de analgesia de rescate postquirúrgica (p = 0.045). Conclusiones: la infusión de lidocaína es efectiva para el manejo del dolor postquirúrgico inmediato, así como disminución de consumo de opioides y dosis de rescate analgésico, con una baja incidencia de náuseas y vómito, pero se asoció a hipotensión transoperatoria.

Abstract: Introduction: having an effective analgesia in the postoperative period is essential to avoid complications associated with pain in patients undergoing laparoscopic cholecystectomy. Objectives: test the effectiveness of intravenous lidocaine for postoperative pain in cholecystectomized patients by laparoscopy. Material and methods: an experimental, randomized, single-blind study was carried out in patients who underwent laparoscopic cholecystectomy at the No. 1 Regional General Hospital in Obregon, Sonora. They were divided into two groups randomly: group L to whom we applied lidocaine 1.5 mg/k in infusion and group P to whom placebo was applied. A statistical analysis was performed in SPSS v. 22 and a p < 0.05 was considered significant. Results: adequate pain management was observed in patients of group L upon admission to PACU (p = 0.002), lower consumption of transoperative fentanyl without statistical difference against placebo (p = 0.086), lower use of post-surgical rescue analgesia (p = 0.045), but higher incidence of adverse effects such as hypotension and bradycardia (p = 0.024). Conclusions: the infusion of lidocaine is effective for the management of immediate postsurgical pain; as well it decreases opioid consumption and analgesic rescue dose, with a low incidence of nausea and vomiting, but associated with hypotension after surgery.

Colecistectomía laparoscópica en una paciente con situs inversus totalis. Reporte de un caso y revisión de la literatura

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.

Bilateral versus unilateral erector spinae plane block for postoperative analgesia in laparoscopic cholecystectomy: a randomized controlled study

Abstract Introduction Laparoscopic cholecystectomy (LC) is the common surgical intervention for benign biliary diseases. Postoperative pain after LC remains as an important problem, with two components: somatic and visceral. Trocar entry incisions lead to somatic pain, while peritoneal distension with diaphragm irritation leads to visceral pain. Following its description by Forero et al., the erector spinae plane (ESP) block acquired considerable popularity among clinicians. This led to the use of ESP block for postoperative pain management for various operations. Materials and methods This study was conducted between January and June 2019. Patients aged between 18 and 65 years with an American Society of Anesthesiologists (ASA) physical status I-II, scheduled for elective laparoscopic cholecystectomy were included in the study. All the patients received bilateral or unilateral ESP block at the T8 level preoperatively according to their groups. Results There was no significant difference between the groups in terms NRS scores either at rest or while coughing at any time interval except for postoperative 6th hour (p = 0.023). Morphine consumption was similar between the groups but was significantly lower in group B at 12 and 24 hours (p = 0.044 and p = 0.022, respectively). Twelve patients in group A and three patients in group B had shoulder pain and this difference was statistically significant (p = 0.011). Discussion In conclusion, bilateral ESP block provided more effective analgesia than unilateral ESP block in patients undergoing elective LC. Bilateral ESP block reduced the amount of opioid consumption and the incidence of postoperative shoulder pain.

Eficacia del atenolol para prevenir la hipertensión perioperatoria en pacientes hipertensos durante la colecistectomía endoscópica

Introducción: La hipertensión perioperatoria constituye una de las principales alteraciones detectadas durante la colecistectomía video endoscópica. Se presume del efecto protector que tiene el atenolol con su acción beta bloqueadora en reducir esta condición morbosa. Objetivo: Evaluar la eficacia del atenolol en prevenir la hipertensión perioperatoria durante la colecistectomía video endoscópica en la unidad quirúrgica del Hospital Clínico Quirúrgico "Lucía Íñiguez Landín" de Holguín Método: Se realizó un estudio observacional, analítico, longitudinal y prospectivo de tipo cohorte con dos grupos paralelos de estudio, uno de tratamiento y un grupo control, desde enero a diciembre de 2018. El universo estuvo constituido por los 697 pacientes (N=697) atendidos en la consulta de evaluación preoperatoria y se tomó como muestra a 183 hipertensos (n=183) que se operaron por cirugía video endoscópica de litiasis vesicular, de ellos aleatorizados 95 al grupo de tratamiento con atenolol y 88 al grupo control. A los pacientes del grupo tratamiento se les administró atenolol 25 mg diarios durante 15 días antes de la cirugía. Las variables principales que se monitorizaron fueron las presiones arteriales sistólica, diastólica y media, y se emplearon indicadores para evaluar la efectividad del tratamiento. Resultados: Las presiones arteriales preoperatorias disminuyeron de forma significativa en el grupo de tratamiento con atenolol. La hipertensión perioperatoria fue más frecuente en el grupo control. El atenolol es un bloqueador selectivo de los receptores beta 1, ejerce su efecto hipotensor a nivel central al deprimir los centros cardiovasculares simpáticos como el vasomotor bulbar. Conclusiones: El tratamiento con atenolol fue eficaz en reducir la incidencia de hipertensión perioperatoria.

Introduction: Perioperative hypertension represents one of the leading alterations detected performing endoscopic cholecystectomy. It is presumed that atenolol has a protective effect able to reduce this morbid condition, likely due to its beta-blocking action. Objective: To assess the efficacy of atenolol on preventing perioperative hypertension performing laparoscopic cholecystectomy in the surgical unit of the Hospital Clínico Quirúrgico "Lucía Íñiguez Landín" of Holguín. Method: An observational, analytical, longitudinal and prospective cohort study was conducted with two study groups at the same time, experimental group and control group, from January to December, 2018. A total of 697 patients (N=697) evaluated in the preoperative consultation were involved in the study, the sample included 183 hypertensive patients (n=183) who underwent endoscopic surgery for gallbladder lithiasis, of whom 95 were randomized to the atenolol treatment group and 88 to the control group. Patients in the treatment group were administered atenolol at 25 mg daily for 15 days before surgery. Leading variables used were systolic, diastolic and mean arterial pressures, and specific indicators were used to evaluate treatment effectiveness. Results: Preoperative arterial pressures decreased significantly with the use of atenolol in the treatment group. Perioperative hypertension was more frequent in the control group. Atenolol is a selective beta 1 receptor blocker, who causes a hypertensive effects in the central level, depressing the bulbar vasomotor center. Conclusions: The results of this investigation show that the use of atenolol in treatment was an effective alternative, thus effectiveness reduce perioperative hypertension rate.

Laparoscopic cholecystectomy is the Gold standard for the treatment of vesicular lithiasis. The present study aims to describe the experience in laparoscopic cholecystectomy of 10 years at Los Pinos Municipal Hospital in La Paz, Bolivia. A review of medical records of hospitalized patients undergoing laparoscopic cholecystectomy from June 2012 to July 2022 was carried out. Case series were 1095 patients; 866 (79.3%) female and 229 (20.7%) male; the age group with higher casuistry was 31 to 40 years (256 cases, 23.3%), the average age was 50.5 (10 to 81 years). The admission of patients was by outpatient 72.5% and emergency unit 27.4%. The average surgery time was 85 min. (20 to 150 min.). The highest prevalence diagnosis at admission was chronic lithiasic cholecystitis (766 cases, 69.9%). The conversion factor to open surgery was the anatomical structures identification difficulty, conversion rate of 6.9 %. The postoperative hospital stay average was 3.5 days (1 to 6 days). Based on the results obtained, laparoscopic cholecystectomy still proves to be the safe and effective treatment in patients with cholelithiasis.

Colecistectomias: análise de um hospital escola / Cholecystectomies - analysis in a school hospital

Introdução: A colecistopatia calculosa atinge cerca de 20% da população ocidental adulta, e dela 15% tornam-se sintomáticos. No Brasil foram realizadas, entre 12/2019 e 11/2020, 138.154 colecistectomias pelo Sistema Único de Saúde Objetivo: Levantar dados das colecistectomias realizadas em 2 anos em um hospital escola, analisando o perfil epidemiológico dos pacientes e resultados operatórios. Método: Foram analizadas 942 colecistectomias. Compararam-se os procedimentos eletivos com os de urgência quanto à necessidade de drenagem, reoperação, complicações pós-operatórias e da ferida operatória. Resultados: Do total, 75,9% eram mulheres com média de 48,2 anos de idade. Procedimentos urgentes foram realizadas em 34,9%. Houve mais complicações nas urgências e nos que necessitaram de drenagem. Houve mais complicações na ferida operatória nos pacientes submetidos à reoperação. Conclusão: A análise dos dados mostrou independência de 5 variáveis na evolução pós-operatória das colecistectomias e elas interferiram negativamente quer por si só, quer em associação. Foram elas: drenagem vs. porta de entrada; drenagem vs. reoperação; porta de entrada vs. complicações pós-operatórias; reoperação vs. complicações no pós-operatório; e reoperação vs. complicações na ferida operatória.

Introduction: Calculous cholecystopathy affects about 20% of the Western adult population, and 15% of them become symptomatic. About 138.154 cholecystectomies were performed between 12/2019 and 11/2020 at Brazil, by the public health system. Objective: To collect data from cholecystectomies performed during 2 years in a teaching hospital, analyzing the epidemiological profile of patients and operative results. Method: 942 cholecystectomies were analyzed. Elective and emergency procedures were compared regarding the need for drainage, reoperation, postoperative and wound complications. Results: Of the total, 75.9% were women with a mean age of 48.2 years. Urgent procedures were performed in 34.9%. There were more complications in emergencies and in those requiring drainage. There were more complications in the surgical wound in patients undergoing reoperation. Conclusion: Data analysis showed independence of 5 variables in the postoperative evolution of cholecystectomies and they negatively interfered either by themselves or in combination. They were: drainage vs. hospital entrance; drainage vs. reoperation; hospital entrance vs. postoperative complications; reoperation vs. postoperative complications; and reoperation vs. complications in the surgical wound.

Colecistectomía Laparoscópica: comparación de Técnica Americana vs Técnica Modificada en relación a elementos de confort del cirujano / Laparoscopic Cholecystectomy: Comparison of the American Technique vs the modified Technique in relation to Surgeon comfort

Introducción: Los cirujanos informaron esfuerzo y dolor musculoesquelético durante o después de un procedimiento. Modificando que la inserción del trócar localizado en línea media clavicular se coloque en línea media, puede mejorar la postura del cirujano. En el Hospital Universitario de Caracas, la técnica de colecistectomía laparoscópica modificada se realiza con frecuencia por disminuir la sensación de esfuerzo y dolor durante el acto quirúrgico. Se plantea el estudio de los elementos de confort para el cirujano con esta técnica modificada. Métodos: Se realizó un estudio prospectivo, descriptivo, comparativo y de corte transversal en cirujanos de pacientes con litiasis vesicular que se resolvieron con colecistectomía laparoscópica, en el Hospital Universitario de Caracas, período enero-agosto 2022. Resultados: Se realizaron 77 colecistectomías laparoscópicas, conformadas por: técnica americana 32 (41,6%) y la técnica modificada 45 (58,4%). La técnica americana evidenció como zona dolorosa la muñeca izquierda (62,5%), y en la técnica modificada reportan en 91,1% sin zona dolorosa. El 43,8% de los cirujanos no se sienten cómodos con la técnica americana, mientras que en la modificada el 97,8% reportaron la técnica cómoda. Los cirujanos refirieron un esfuerzo difícil en el 56,3% con la técnica americana y con la modificada el 82,2% refieren un esfuerzo leve. El grado de dolor en las extremidades fue mayor en los que realizaron la técnica americana en comparación con la modificada, siendo todos los resultados estadísticamente significativos. Conclusión: La técnica modificada tiene ventajas en cuanto a la comodidad del cirujano y su equipo de trabajo y puede emplearse desde el inicio de la formación de cirujanos(AU)

Conclusión: A step-by-step laparoscopic cholecystectomy in a dynamic and innovative way with an audiovisual support that facilitate learning.

¿Día o noche? El momento ideal para realizar la colecistectomía / Day or night? The right time to perform cholecystectomy

Introducción. La frecuencia de complicaciones postquirúrgicas de la colecistectomía realizada en la noche es un tema de controversia, siendo que se ha reportado una frecuencia mayor durante el horario nocturno. El objetivo de este estudio fue analizar la presentación de colecistectomía difícil dependiendo de la hora en que se realizó la cirugía, además de otras complicaciones, estancia intrahospitalaria postquirúrgica, reingreso a 30 días y reintervención. Métodos. Se realizó un estudio retrospectivo, observacional, analítico y transversal, comparando la presentación de colecistectomía difícil y su frecuencia en horario diurno (8:00 am a 7:59 pm) y nocturno (8:00 pm a 7:59 am), además de seroma, absceso, hematoma, fuga biliar, biloma, estancia intrahospitalaria postquirúrgica, reingreso a 30 días y reintervención. Resultados. Se incluyeron en el estudio 228 pacientes, 117 operados durante el día (52 %) y 111 durante la noche (48 %). La colecistectomía difícil se presentó 26 % vs 34 % de los casos intervenidos en el día y la noche, respectivamente. La complicación más frecuente fue seroma (14 %). La estancia hospitalaria media fue de 2,7 días en cirugías diurnas y de 2,5 en cirugías nocturnas; hubo 3 % de reintervenciones y 6 %, respectivamente. También hubo 2 % de reingresos a los 30 días entre los pacientes operados en el día y 3 % entre los operados en la noche. Conclusiones. La frecuencia de colecistectomía difícil y las complicaciones, la estancia intrahospitalaria postquirúrgica, el reingreso a 30 días y la necesidad de reintervención, no tuvieron diferencias significativas respecto al horario de la cirugía.

Introduction. The frequency of post-surgical complications of cholecystectomy performed overnight is a matter of controversy, and a higher rate has been reported during the night shift. The objective of this study was to analyze the presentation of difficult cholecystectomy depending on the time the surgery was performed, in addition to other complications, postoperative hospital stay, 30-day readmission, and reintervention. Methods. A retrospective, observational, analytical and cross-sectional study was carried out, comparing the presentation of difficult cholecystectomy and its frequency during daytime (8:00 am to 7:59 pm) and at night (8:00 pm to 7:59 am), in addition of seroma, abscess, bile leak, biloma, hematoma, post-surgical hospital stay, 30-day readmission, and reintervention.Results. A total of 228 patients were included in the study, 117 patients operated during the day (52%), and 111 at night (48%). Difficult cholecystectomy occurred in 26% vs. 34% of the cases operated on during the day and at night, respectively. The most frequent complication was seroma (14%). The mean hospital stay was 2.7 days in day surgeries and 2.5 in night surgeries; there were also 2% readmission at 30 days among patients operated during the day and 3% among those operated on at night. Conclusions. The frequency of difficult cholecystectomy and complications, postoperative hospital stay, 30-day readmission, and the need of reintervention, did not have significant differences with respect to the time of surgery.

Lesiones de vía biliar poscolecistectomía: conducta terapéutica actual / Post Cholecystectomy Bile Duct Injuries: Current Therapeutic Option

Resumen La colecistolitiasis es una condición común en Chile. La complicación más frecuente de esta condición es la colecistitis aguda. Aproximadamente 60.000 colecistectomías son realizadas anualmente en nuestro país, convirtiéndola en una de las patologías digestivas más frecuentes. El tratamiento de la colelitiasis ha evolucionado las últimas dos décadas. Con el desarrollo de la laparoscopía a final de 1980, la colecistectomía abierta fue definitivamente sustituida en los 90 por la vía laparoscópica. Desafortunadamente, la generalización de este procedimiento produjo un aumento en la incidencia de lesiones de vía biliar, aumentando desde una 0,1-0,2% hasta un 0,5-0,7%. Si bien, con el progresivo entrenamiento de los cirujanos en la cirugía mínimamente invasiva esta cifra ha disminuido nuevamente, la LVB aún constituye una de las complicaciones más graves en cirugía, generando gran impacto en la calidad de vida del paciente, e incluso costos en salud que pueden llegar a ser devastadores. El manejo de una lesión de vía biliar es, para muchos cirujanos, un desafío quirúrgico, que para su resolución requiere de las habilidades y experiencia de un cirujano hepatobiliar y derivación a centros de salud especializados. Sin duda, la acción más importante es extremar de manera rutinaria las medidas de prevención. Sin embargo, una vez que la lesión se ha producido, el futuro del paciente depende, directamente, del buen criterio del cirujano, tanto para realizar un diagnóstico temprano, como del enfrentamiento terapéutico que realice. El objetivo de este trabajo es dar a conocer diferentes conductas preventivas y terapéuticas cuando esta complicación se presenta.

Calculous biliary disease is a common condition in Chile. Over 60.000 cholecystectomies are performed annually, making gallstone disease one of the most common digestive health problems. The treatment of calculous biliary disease has evolved over the last 2 decades. With the development of laparoscopic technology in the late 1980s, new techniques for cholecystectomy were introduced. By the early 1990s, laparoscopic cholecystectomy had replaced open cholecystectomy in the operative management of gallbladder stone disease. Unfortunately, the widespread application of laparoscopic cholecystectomy has led to a concurrent rise in the incidence of major bile duct injuries. Reports have estimated the incidence has risen from 0.1-0.2 to 0.5-0.7%. Although, exponential training of surgeons in minimally invasive surgery has led to decrease this numbers again, bile duct injuries still constitute one of the most serious complications in surgery, generating a great impact on the patient's quality of life, and even health costs that can be devastating. The management of patients following major bile duct injurie is a surgical challenge, often requiring the skills of experienced hepatobiliary surgeons at tertiary referral centers. In this setting, the most important action is to routinely maximize prevention measures. However, once injury has occurred, patient's future depends directly on the correct judgment of the surgeon, both to make an early diagnosis and to choose the best therapeutic confrontation. The objective of this article is to present the different preventive and therapeutic options available when this complication occurs.

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.

Uso de la dexametasona para la prevención de náuseas y vómitos posoperatorios en pacientes tratados con colecistectomía laparoscópica / Use of dexamethasone for the prevention of postoperative nausea and vomiting in patients treated with laparoscopic cholecystectomy

Introducción: Las náuseas y los vómitos posoperatorios muestran una alta incidencia con los procedimientos laparoscópicos y, además, se han posicionado como un marcador de calidad en anestesiología. Objetivo: Determinar la efectividad de la dexametasona en la prevención de náuseas y vómitos posoperatorios en pacientes operados de la vesícula biliar. Métodos: Se realizó una intervención terapéutica en 100 pacientes operados de la vesícula biliar mediante laparoscopia con anestesia general balanceada, en el Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de enero a diciembre de 2018. Para ello, se conformaron dos grupos: uno de estudio, tratado con dexametasona, y otro de control, que recibió un placebo; cuyos integrantes fueron seleccionados en igual número (50 para cada grupo) por el método aleatorio simple. Resultados: En ambos grupos se obtuvo una mayor frecuencia de las edades de 33 a 46 años y del sexo femenino. Las náuseas posoperatorias se identificaron en 24,0 % del grupo de estudio, mientras que, en el de control, figuraron en un porcentaje superior (52,0). También disminuyó el número de pacientes con vómitos al aplicar la dexametasona, pues 90,0 % de aquellos que la recibieron no presentaron esta reacción adversa en el período posoperatorio, en comparación con 72,0 % de controles. Conclusiones: La dexametasona redujo la aparición de náuseas y vómitos posoperatorios, de modo que puede resultar efectiva en la prevención de estos efectos secundarios en pacientes intervenidos por colecistectomía laparoscópica.

Introduction: The postoperative nausea and vomiting show a high incidence with the laparoscopic procedures and, also, they have been positioned as a marker of quality in anesthesiology. Objective: To determine the effectiveness of dexamethasone in the prevention of postoperative nausea and vomiting in patients operated on for gall bladder. Methods: A therapeutic intervention was carried out in patients operated on for gall bladder by means of laparoscopy with balanced general anesthesia, at Dr. Juan Bruno Zayas Alfonso Teachig General Hospital in Santiago de Cuba, from January to December, 2018. Two groups were conformed: a study group, treated with dexamethasone, and a control group that received a placebo; whose members were selected in same number (50 for each group) by the simple random method. Results: In both groups a higher frequency of the 33 to 46 ages and the female sex was obtained. The postoperative nausea were identified in 24.0 % of the study group, while, in the control group, it was higher percentage (52.0). Also the number of patients vomiting diminished when applying dexamethasone, because 90.0 % of those that received it didn't present this adverse reaction in the postoperative period, in comparison with 72.0 % of controls. Conclusions: Dexamethasone reduced the appearance of postoperative nausea and vomiting, so that can be effective in the prevention of these secondary effects in patients intervened by laparoscopic cholecystectomy.
