ABSTRACT

En pacientes con infección por SARS-CoV-2 la intubación endotraqueal es un procedimiento con riesgo elevado de contagio. La videolaringoscopia complementa la protección del profesional, pero los videolaringoscopios comerciales son caros y no siempre están disponibles en las terapias intensivas pediátricas argentinas. El objetivo fue describir la práctica de intubación en un modelo de cabeza de simulación de lactante con un videolaringoscopio artesanal de bajo costo.Quince pediatras sin experiencia previa con el dispositivo participaron de una práctica de intubación en una cabeza de simulación con un videolaringoscopio artesanal. El tiempo promedio del primer intento fue de 116,4 segundos (intervalo de confianza del 95 % [IC95 %]: 84,8-148,0) y, el del siguiente fue de 44,2 segundos (IC95 %: 27,7­60,6). El tiempo disminuyó de forma significativa en el segundo intento (p : 0,0001). El dispositivo permitió la intubación exitosa en todos los intentos acortando la duración del procedimiento en la segunda práctica


In patients with SARS-CoV-2 infection, endotracheal intubation is a procedure with a high risk for transmission. A videolaryngoscopy is a supplementary level of health care provider protection, but commercial videolaryngoscopes are expensive and not always available in pediatric intensive care units in Argentina. Our objective was to describe intubation practice using an infant head mannequin with a low-cost, handcrafted videolaryngoscope.Fifteen pediatricians with no prior experience using the device participated in an intubation practice in a head mannequin with a handcrafted videolaryngoscope. The average time for the first attempt was 116.4 seconds (95 % confidence interval [CI]: 84.8-148.0) and, for the second one, 44.2 seconds (95 % CI: 27.7-60.6). Time decreased significantly for the second attempt (p: 0.0001).A successful intubation was achieved with the device in all attempts, and the procedure duration decreased with the second practice

ABSTRACT

Abstract Objective To evaluate the feasibility of magnetic resonance imaging (MRI) to obtain the critical shoulder angle (CSA) comparing the results obtained through radiography and MRI, and assess the learning curves. Methods In total, 15 patients were evaluated in a blinded and randomized way. The CSA was measured and compared among groups and subgroups. Results The mean angles measured through the radiographic images were of 34.61 ± 0.67 and the mean angles obtained through the MRI scans were of 33.85 ± 0.53 (p = 0.29). No significant differences have been found among the groups. The linear regression presented a progressive learning curve among the subgroups, from fellow in shoulder surgery to shoulder specialist and radiologist. Conclusion There was no statistically significant difference in the X-rays and MRI assessments. The MRI seems to have its efficacy associated with more experienced evaluators. Data dispersion was smaller for the MRI data regardless of the experience of the evaluator.


Resumo Objetivo Avaliar a confiabilidade da obtenção do ângulo crítico do ombro (ACO) na ressonância magnética (RM) comparada com esse mesmo ângulo obtido por meio de radiografias, e avaliar a curva de aprendizado do método. Métodos As imagens de radiografias e RMs de 15 pacientes foram avaliadas prospectivamente de forma cega e randômica. O ACO foi medido e comparado entre os grupos e subgrupos. Resultados A média dos ACOs nas imagens de radiografia foi de 34,61º ± 0,67, e, na RM, 33,85º ± 0,53 (p = 0,29). Não houve diferença estatisticamente significativa. Houve curva de aprendizado progressiva na regressão linear entre os subgrupos, de especializando em ombro a especialista e radiologista. Conclusão Não houve diferença estatisticamente significativa entre o ACO por imagens de radiografia e RM. O método da RM parece ter sua eficiência associada a avaliadores mais experientes. Independente da experiência do avaliador, a variabilidade dos dados foi menor nas avaliações por RM.

ABSTRACT

ABSTRACT BACKGROUND: Endoscopic submucosal dissection (ESD) enables en bloc excision of superficial neoplasms. Although ESD is widely practiced in Eastern countries like Japan, South Korea and China, its use in the West is supposed to be still limited to few tertiary centers. OBJECTIVE: This study aimed to investigate the clinical practice of ESD in Brazil by means of an electronic questionnaire elaborated by the Brazilian Society of Digestive Endoscopy (SOBED). METHODS: In October 2019, 3512 endoscopist members of SOBED were invited to respond to an electronic survey containing 40 questions divided into four topics: operator profile; clinical experience with ESD; adverse events and training. Informed consent was requested to all participants. The investigators reviewed all responses and considered valid if more than 50% of the questions were answered and additional information, when requested, was provided. RESULTS: A total of 155 (4.4%) qualified responses entered the study. ESD has been practiced in 22 of 26 Federation States and majority of respondents (32.2%) have 10 to 20 years of practice. ESD has been performed more frequently in private hospitals (101 individuals, 66.9%) and private ambulatory centers (41 individuals, 27.1%). ESD was performed mainly in the stomach (72%), followed by the rectum (57%) and 80% of the individuals reported less than 25 operations. Twenty-four (15.4 %) individuals reported perforation and 4 (2.5%) of them reported postoperative deaths. Approximately a quarter of responders denied hands-on training in models or visit to training centers. CONCLUSION: ESD appears to be practiced throughout the country, not only in tertiary or academic institutions and mainly in private practice. Most operators received limited training and still are at the beginning of their learning curve. The reported adverse events and mortality rates appear to be higher than Eastern reports.


RESUMO CONTEXTO: A dissecção endoscópica da submucosa (ESD) é uma técnica popular no Japão e em outros países asiáticos e, supostamente, ainda está limitada a centros terciários no Ocidente. OBJETIVO: Este estudo teve como objetivo investigar a prática clínica da ESD no Brasil por meio de um questionário eletrônico elaborado pela Sociedade Brasileira de Endoscopia Digestiva (SOBED). MÉTODOS: Em outubro de 2019, 3512 endoscopistas membros da SOBED foram convidados a responder a uma pesquisa eletrônica contendo 40 questões divididas em quatro tópicos: perfil do operador; experiência clínica com ESD; eventos adversos e treinamento. O consentimento informado foi solicitado a todos os participantes. Os investigadores analisaram todas as respostas e consideraram válidas se mais de 50% das perguntas fossem respondidas e informações adicionais, quando solicitadas, fossem fornecidas. RESULTADOS: Um total de 155 (4,4%) respostas qualificadas foram incluídas no estudo. A ESD foi executada em 22 dos 26 estados da Federação e a maioria dos entrevistados (32,2%) possuía de 10 a 20 anos de prática endoscópica. A ESD foi realizada com maior frequência em hospitais privados (101 indivíduos; 66,9%) e clínicas ambulatoriais privadas (41 indivíduos; 27,1%). A ESD foi realizada principalmente no estômago (72%), seguido pelo reto (57%) e 80% dos indivíduos relataram menos de 25 operações. Vinte e quatro (15,4%) indivíduos relataram algum caso de perfuração no procedimento e 4 (2,5%) deles relataram óbito pós-operatório. Aproximadamente um quarto dos respondentes negou treinamento prático em modelos ou visita a centros de treinamento. CONCLUSÃO: A ESD parece ser praticada em todo o país, não apenas em instituições terciárias ou acadêmicas e principalmente na prática privada. A maioria dos respondedores recebeu treinamento limitado e ainda está no início da curva de aprendizado. Os eventos adversos relatados e as taxas de mortalidade parecem ser maiores do que os relatos orientais.

ABSTRACT

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


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

ABSTRACT

Resumen La primera colectomía laparoscópica se realizó hace casi 30 años. La adopción como estándar de tratamiento ha sido lenta, a pesar de compartir los beneficios de la cirugía con invasión mínima, como el menor dolor, estadía hospitalaria y recuperación precoz. Esto se explica por el temor generado por reportes iniciales que señalaban la aparición de implantes en los sitios de inserción de los trocares y las dudas sobre la seguridad oncológica. Distintos ensayos clínicos aleatorizados finalmente confirmaron su seguridad y eficacia en el tratamiento del cáncer de colon con resultados comparables a la cirugía abierta. La curva de aprendizaje prolongada, dada por la complejidad técnica, ha incentivado el aprendizaje supervisado por un entrenador experto en el contexto de programas de formación de subespecialidad. Nuestro objetivo es realizar una revisión de los resultados a corto y largo plazo y algunas consideraciones generales y perspectivas futuras.


The first laparoscopic colectomy was performed almost 30 years ago, its expansion has been slow and it did not have the explosive development that laparoscopic cholecystectomy and appendectomy had, despite sharing its benefits such as lower pain, hospital stay and early recovery. This is explained, in part, by the initial fear of implants at trocar sites and the lack of oncological safety. Randomized clinical trials confirmed the safety and efficacy of laparoscopic surgery with short-term and oncological results, comparable to open surgery. The slow learning curve, given by technical complexity, has encouraged learning supervised by an expert coach in the context of subspecialty training programs. Our aim is to review the short-term and oncological results, some general considerations and future perspectives.

ABSTRACT

Resumen Objetivos: presentar el desarrollo de modelos educativos para el aprendizaje de dos técnicas endoscópicas vigentes, ampliamente difundidas y de gran implicación clínica, con la única intención de permitir la adquisición de destrezas básicas y avanzadas a residentes y gastroenterólogos. Materiales y métodos: se idearon dos modelos sencillos, de muy bajo costo, fácilmente reproducibles y reutilizables, con los cuales se logra ejecutar la totalidad de los procedimientos descritos. Además, permiten al operador integrar el desarrollo de habilidades y la adquisición de los conceptos teóricos mínimos requeridos, sin las presiones generadas por el riesgo existente de complicaciones. Resultados: la tendencia actual a nivel mundial se conduce hacia el desarrollo de modelos de enseñanza que aceleren la curva de aprendizaje, así como de procedimientos altamente exigentes y asociados a complicaciones potencialmente graves. Con estos modelos es posible poner a prueba al endoscopista, mediante una evaluación continua y supervisada. Su implementación en unidades de gastroenterología es sencilla, sin la necesidad de una inversión superlativa o el desplazamiento a otros países. Conclusiones: se trata de un gran aporte al desarrollo científico y educativo de nuestro país, ya que la creación y la implementación de nuevas técnicas endoscópicas y su aprendizaje no deben ser asumidos por los pacientes. En este punto, estamos de acuerdo con los conceptos emitidos por diferentes asociaciones médicas respecto a que los cursos teórico-prácticos de corta duración -y en algunas ocasiones virtuales- no constituyen una formación mínima, requerida para lograr la acreditación.


Abstract Objectives: This article presents the development of educational models for learning two widespread recent endoscopic techniques which have great clinical implications. Its sole intention is to allow acquisition of basic and advanced skills by residents and gastroenterologists. Materials and methods: Two simple, very low cost, easily reproducible and reusable models were devised. Procedures are fully described in ways that allow the operator to integrate the development of skills and acquisition of the minimum theoretical concepts required without the pressures generated by risks of complications. Results: The current global trend is to develop teaching models that accelerate the learning curve for highly demanding procedures that are associated with potentially serious complications. With these models it is possible to test endoscopists through continuous supervised evaluations. Implementation by gastroenterology units can be done easily without the need for large investments or travel to other countries. Conclusions: This is a great contribution to the scientific and educational development of Colombia since neither development of new endoscopic techniques nor the process of learning how to perform them should put patients at risk. We agree with the ideas of numerous medical associations regarding theoretical-practical courses of short duration even though some virtual sessions, "do not constitute the minimum training required needed for accreditation".

ABSTRACT

Resumen Introducción: La duodeno pancreatectomía cefálica es una operación compleja cuyos resultados a corto plazo son multifactoriales. Objetivo: Evaluar el impacto de la curva de aprendizaje en los resultados a corto plazo de la duodenopancreatectomía cefálica en un hospital de nivel II. Materiales y Método: Se analizaron los datos obtenidos a partir de una base de datos mantenida prospectivamente desde 2005. Se definieron dos periodos de tiempo: de 2005 a 2011 y de 2012 a 2017. Se compararon la morbilidad, mortalidad y estancia postoperatoria de ambos períodos. Resultados: Durante el período de tiempo estudiado se hicieron 126 duodenopancreatectomías cefálicas, 61 durante la primera etapa y 65 durante la segunda. La tasa de transfusión intraoperatoria se redujo de 33% a 15% (p = 0,011). La tasa de transfusión postoperatoria se redujo de 39 a 23% (p = 0,021). No hubo diferencias significativas con respecto a la incidencia global de complicaciones postoperatorias (59% y 52,3%). La incidencia de abscesos intraabdominales fue significativamente menor en el segundo período (18% y 4,6%, respectivamente; p = 0,038). La tasa de reintervenciones se redujo significativamente, de 22% a 9% (p = 0,049). También se redujo significativamente la tasa de mortalidad, de 6,56% a 0% (p = 0,032). La estancia media postoperatoria disminuyó significativamente en el segundo período, pasando de 19,6 a 15,8 días (p = 0,001), con una mayor proporción de pacientes dados de alta en los 8 primeros días de postoperatorio (11,5% y 38,5%, respectivamente; p = 0,001). Conclusión: La curva de aprendizaje es un factor que permite mejorar los resultados de la duodenopancreatectomía cefálica, en un hospital de nivel II, hasta alcanzar valores similares a los de un hospital de nivel III.


Introduction: The duodenum pancreatectomy cephalic is a complex operation whose short-term results are multifactorial. Aim: To assess the impact of the learning curve on the short-term outcomes of cephalic duodenopancreatectomy at a level II hospital. Materials Method: We analyze the data obtained from a database maintained prospectively since 2005. Two time periods were defined: from 2005 to 2011 and from 2012 to 2017. The morbidity, mortality and postoperative stay of both periods were compared. Results: 126 cephalic duodenopancreatectomies were performed, 61 during the first period and 65 during the second. The intraoperative transfusion rate was reduced from 33% to 15% (p = 0.011). The postoperative transfusion rate was reduced from 39 to 23% (p = 0.021). There were no significant differences with respect to the overall incidence of postoperative complications (59% and 52.3%, respectively). However, the incidence of intra-abdominal abscesses was significantly lower in the second period (18% and 4.6%, respectively, p = 0.038). The rate of reoperations was significantly reduced, from 22% to 9% (p = 0.049). The mortality rate was also significantly reduced, from 6.56% to 0% (p = 0.032). The mean postoperative stay decreased significantly in the second period, from 19.6 to 15.8 days (p = 0.001), with a higher proportion of patients discharged in the first 8 postoperative days (11.5% and 38.5%, respectively, p = 0.001). Conclusion: The learning curve is a factor allows improving the results of cephalic pancreaticoduodenectomy, in a level II hospital, until reaching values similar to those of a level III hospital.

ABSTRACT

Abstract Introduction: The endoscopic methods are progressing and becoming more common in routine clinical diagnosis in the field of otorhinolaryngology. Relatively large amount of researches have proved high accuracy of narrow band imaging endoscopy in differentiating benign and malignant lesions within vocal folds. However, little is known about learning curve in narrow band imaging evaluation of laryngeal lesions. Objective: The aim of this study was to determine the learning curve for the narrow band imaging evaluation of vocal folds pathologies depending on the duration of the procedure. Methods: Records of 134 narrow band imaging that were analyzed in terms of the duration of the procedure and the accuracy of diagnosis confirmed by histopathological diagnosis were enrolled in the study. The narrow band imaging examinations were performed sequentially by one investigator over a period of 18 months. Results: The average duration of narrow band imaging recordings was 127.82 s. All 134 studies were divided into subsequent series of several elements. An evident decrease in time of investigation was noticed between 13th and 14th series, when the examinations were divided into 5 elements series, which corresponds to the difference between 65th and 70th subsequent narrow band imaging examination. Parallel groups of 67 examinations were created. Group 1 included 1st to 67th subsequent narrow band imaging examination; Group 2 - 68th to 134th narrow band imaging examinations. The non-parametric U Mann-Whitney test confirmed statistically significant difference between the mean duration of narrow band imaging examination in both groups 160.5 s and 95.1 s, respectively (p < 10−7). Sensitivity and specificity of narrow band imaging examination in the first group were respectively: 83.7% and 76.7%. In the second group, these indicators amounted 98.1% and 80% respectively. Conclusions: A minimum of 65th-70th narrow band imaging examinations are required to reach a plateau phase of the learning process in assessment of glottis lesions. Analysis of learning curves is useful for the development of training programs and determination of a mastery level.


Resumo Introdução: Os métodos endoscópicos estão progredindo e se tornando comuns no diagnóstico clínico de rotina também na otorrinolaringologia. Um número relativamente grande de pesquisas demonstrou alta precisão na endoscopia com imagem de banda estreita na diferenciação de lesões benignas e malignas nas pregas vocais. Entretanto, pouco se sabe sobre a curva de aprendizado na avaliação da de banda estreita de lesões laríngeas. Objetivo: Determinar a curva de aprendizado para a avaliação por imagem de banda estreita das afecções das pregas vocais, de acordo com a duração do procedimento. Método: Foram incluídos no estudo 134 registros de imagens de banda estreita analisadas em termos da duração do procedimento e da acurácia do diagnóstico confirmado pelo diagnóstico histopatológico. Os exames com imagem de banda estreita foram feitos sequencialmente por um investigador por 18 meses. Resultados: A duração média dos registros de imagem de banda estreita foi de 127,82s. Todos os 134 estudos foram divididos em séries subsequentes de vários elementos. Uma evidente diminuição no tempo de investigação foi observada entre as séries 13 e 14, quando os exames foram divididos em séries de cinco elementos, o que corresponde à diferença entre o 65° e 70° exames de imagem de banda estreita subsequentes. Foram criados grupos paralelos de 67 exames. O grupo 1 incluiu o 1° ao 67° exame de imagem de banda estreita subsequente; Grupo 2 - o 68° ao 134° exame de imagem de banda estreita. O teste não paramétrico U de Mann-Whitney confirmou uma diferença estatisticamente significante entre a duração média do exame de imagem de banda estreita em ambos os grupos de 160,5s e 95,1s, respectivamente (p < 10-7). A sensibilidade e especificidade do exame de imagem de banda estreita no primeiro grupo foram, respectivamente: 83,7% e 76,7%. No segundo grupo, esses indicadores foram 98,1% e 80%, respectivamente. Conclusões: Um mínimo de 65 a 70 exames de imagem de banda estreita é necessário para se atingir a fase de estabilização (plateau) do processo de aprendizado na avaliação de lesões de glote. A análise das curvas de aprendizado é útil para o desenvolvimento de programas de treinamento e determinar o n.

ABSTRACT

ABSTRACT Introduction: To evaluate the influence of previous experience as bedside assistants on patient selection, perioperative and pathological results in robot assisted laparoscopic radical prostatectomy. Materials and Methods: The first 50 cases of two robotic surgeons were reviewed retrospectively. Group 1 consisted of the first 50 cases of the surgeon with previous experience as a robotic bedside assistant between September 2016-July 2018, while Group 2 included the first 50 cases of the surgeon with no bedside assistant experience between February 2009-December 2009. Groups were examined in terms of demographics, prostate volume, presence of median lobe, prostate specific antigen (PSA), preoperative Gleason score, positive core number, clinical stage, console surgery time, estimated blood loss, postoperative Gleason score, pathological stage, positive surgical margin rate, postoperative complications, length of hospital stay and biochemical recurrence rate. Results: Previous abdominal surgery and the presence of median lobe hypertrophy rates were higher in Group 1 than in Group 2 (20% vs. 4%, p=0.014; 24% vs. 6%, p=0.012; respectively). In addition, patients in Group 1 were in a higher clinical stage than those in Group 2 (cT2: 70% vs. 28%, p=0.001). Median console surgery time and median length of hospital stay was significantly shorter in Group 1 than in Group 2 (170 min vs. 240 min, p=0.001; 3 vs. 4, p=0.022; respectively). Clavien grade 3 complication rate was higher in Group 2 but was statistically insignificant. Conclusion: Our findings might reflect that previous bedside assistant experience led to an increase in self-confidence and the ability to manage troubleshooting and made it more likely for surgeons to start with more difficult cases with more challenging patients. It is recommended that novice surgeons serve as bedside assistants before moving on to consoles.

ABSTRACT

ABSTRACT Purpose: To prospectively evaluate the association of adherent perinephric fat (APF) on perioperative outcomes of robotic-assisted partial nephrectomy (RAPN) following elimination of the surgical learning curve. Materials and Methods: 305 consecutive RAPNs performed by a single experienced surgeon were analyzed. The first 100 RAPNs were considered the learning curve and therefore excluded. APF was defined as the necessity of subcapsular renal dissection to mobilize the tumor from surrounding perinephric fat. Perioperative outcomes were evaluated including operative time, warm ischemia time (WIT), postoperative complications, length of stay, margins, ischemia, and complications score (MIC), estimated blood loss (EBL), and change in pre-operative to postoperative day 1 (POD 1) laboratory values. After correction for multiple comparisons, P values ≤0.0045 were considered statistically significant but associations with P values ≤0.05 were also mentioned in the study results. Results: Fifty-eight (28.3%) patients had APF. Patients with APF had longer operative times compared to those without APF (median, 213 vs. 192 minutes, P <0.001). There was some evidence of higher increase in change in creatinine from preoperative to POD 1 among those with APF compared to those without APF, although this was not statistically significant (median, 0.2 vs. 0.1mg/dL, P=0.03). There were no other statistically significant associations between presence of APF and perioperative outcomes. Conclusions: APF is associated with increased operative time but no change in other perioperative outcomes. Surgeon experience does not affect perioperative outcomes associated with APF.

ABSTRACT

La cirugía protésica de rodilla es un procedimiento ampliamente aceptado como etapa final del tratamiento de la artrosis de rodilla, con sobrevida que supera el 90% a 10­15 años. Dentro de las principales causas de fallo, se encuentran la infección (20,4%) y el aflojamiento mecánico (20,3%). El uso de ayudas tecnológicas en cirugía está en constante desarrollo, con el objetivo de mejorar la precisión del acto quirúrgico. En ese escenario, la Cirugía Asistida por Computador (CAS) en artroplastia de rodilla, crece de forma exponencial, y apunta a mejorar el posicionamiento y selección del tamaño de los componentes protésicos, aumentar la precisión de las resecciones óseas y mejorar el balance de los tejidos blandos, logrando así una mayor sobrevida del implante. En comparación a las técnicas convencionales, la cirugía robótica ha mostrado mejores resultados funcionales, al primer año de seguimiento, en términos de rango articular, menor dolor post-operatorio y menor tiempo de estadía hospitalaria. Pero todavía es necesario establecer si, a largo plazo, esas diferencias funcionales se traducirán en mejores resultados clínicos que permitan, de forma consistente, inclinar la balanza en favor de la técnica asistida por robot por sobre las técnicas tradicionales.


Prosthetic knee surgery is a widely accepted procedure as the final stage in the treatment of knee osteoarthritis, with survival rate over 90% at 10 - 15 years. Among the main causes of failure are infection (20.4%) and mechanical loosening (20.3%). The use of technological aids in surgery is in constant development, with the aim of improving the accuracy of the surgical act. In this scenario, Computer-Aided Surgery (CAS) in knee arthroplasty grows exponentially, and aims to improve the positioning and selection of the size of the prosthetic components, increase the accuracy of bone resections and improve the balance of soft tissues, thus achieving a greater survival of the implant. Compared to conventional techniques, robotic surgery has shown better functional results at the first year of follow-up, in terms of joint range, less post-operative pain and shorter hospital stay. It is still necessary to establish whether, in the long term, these functional differences will result in better clinical results that will allow - in a consistent manner - to tip the balance in favor of robot-assisted technique over traditional techniques.

ABSTRACT

Background: Liver transplantation (LT) is an option for people with liver failure who cannot be cured with other therapies and for some people with liver cancer. Aim: To describe, and analyze the first 300 LT clinical results, and to establish our learning curve. Material and Methods: Retrospective cohort study with data obtained from a prospectively collected LT Program database. We included all LT performed at a single center from March 1994 to September 2017. The database gathered demographics, diagnosis, indications for LT, surgical aspects and postoperative courses. We constructed a cumulative summation test for learning curve (LC-CUSUM) using 30-day post-LT mortality. Mortality at 30 days, and actuarial 1-, and 5-year survival rate were analyzed. Results: A total of 281 patients aged 54 (0-71) years (129 women) underwent 300 LT. Ten percent of patients were younger than 18 years old. The first, second and third indications for LT were non-alcoholic steatohepatitis, chronic autoimmune hepatitis and alcoholic liver cirrhosis, respectively. Acute liver failure was the LT indication in 51 cases (17%). The overall complication rate was 71%. Infectious and biliary complications were the most common of them (47 and 31% respectively). The LC-CUSUM curve shows that the first 30 patients corresponded to the learning curve. The peri-operative mortality was 8%. Actuarial 1 and 5-year survival rates were 82 and 71.4%, respectively. Conclusions: Outcome improvement of a LT program depends on the accumulation of experience after the first 30 transplants and the peri-operative mortality directly impacted long-term survival.

ABSTRACT

Family planning is a key intervention to decrease the mortality rates and maternal morbidity, and neonatal mortality rates of children by mean of the preventiion of unwanted pregnancies, the same as pregnancies that happen very clsely to another previous one with little space between them. Several studies performed in different parts of the world have demonstrated adverse results related specially with the spaciament of the pregnancies. The risks are particularly higher with women wich get pregnant les after than a previous deliver, spontaneous abortion or induced abortion. The instrauterine device (ID) is a family planning higly efficacious with a prolongued action and reversible, that offers security to most postpartum women, including those who are still nursing. The primary aim of the present report was to determine the frequency in the placement of the DIUPP in our Obstetrical Department between 01/06/2017 and 30/06/2018, and in a second instance, to describe the method for placement of the DIUPP, to determine the curve of learning, to measure the rate of expulsion of the device, and to evaluate the conformity of the users of the method. Unplanned pregnancies have strongly increased, and for that circumstance, we believe that with new strategies, such as it is with the post-event anticonception, we can improve the reproducive health (AU)

ABSTRACT

Introducción. El tratamiento laparoscópico de la hernia inguino-crural ha dirigido su atención a la curva de aprendizaje técnica, para alcanzar un adecuado desarrollo de la misma. El dominio de las habilidades, no el número de repeticiones, se correlaciona con mejores resultados. La curva de aprendizaje se define como el tiempo y el esfuerzo necesarios para lograr dicha competencia. El objetivo de este trabajo fue analizar el tiempo operatorio como indicador en la adquisición de habilidades y competencias en la curva de aprendizaje de la hernioplastia laparoscópica. Material y método. Se analizaron las hernioplastias laparoscópicas transabdominopreperitoneal (TAPP) intervenidas desde junio del 2013 a mayo del 2018, realizadas por residentes de tercer año de su formación. Se evaluó por separado las hernias unilaterales y las bilaterales, y se registró el tiempo quirúrgico de cada procedimiento realizado durante los meses iniciales de julio, agosto y septiembre; y los meses finales de marzo, abril y mayo de cada año lectivo. Fueron excluidas las hernias endoscópicas TEP, hernias T3 y recidivadas. Se promediaron los tiempos iniciales y finales por cada año. Se analizaron las medias de cada período y se compararon utilizando tests no paramétricos. Resultados. De un total de 1365 hernioplastias laparoscópicas realizadas durante este período, se analizaron 358 casos realizados por residentes durante sus 3 meses iniciales y 3 meses finales de cada año durante 5 años consecutivos. Se evidenció una disminución promedio de tiempo del 25.4% (19.4 min) en hernioplastias unilaterales y del 28.5% (33,6 min) en bilaterales. El número de procedimientos necesarios para evidenciar la reducción del tiempo quirúrgico fue de 78 casos por residente. Conclusiones. Nuestros hallazgos mostraron la reducción del tiempo quirúrgico durante la curva de aprendizaje una vez superados los 78 procedimientos. La hernioplastia laparoscópica es segura y reproducible cuando es realizada bajo la supervisión de cirujanos con experiencia en la reparación por vía laparoscópica. Con un programa adecuado de entrenamiento y la estandarización de la técnica, esta se puede aprender de forma rápida, hábil y segura.(AU)

ABSTRACT

Antecedentes: desde la introducción de la funduplicatura laparoscópica en 1991 para tratar la enfermedad por reflujo gastroesofágico, se han desarrollado diferentes procedimientos mininvasivos hasta llegar en la actualidad a las esofagectomías totalmente toracoscópicas y laparoscópicas. Objetivo: analizar los eventos adversos durante la esofagectomía mininvasiva en posición prona durante la curva de aprendizaje. Material y métodos: en el período comprendido entre noviembre de 2011 y junio de 2017 fueron intervenidos quirúrgicamente en el Hospital Interzonal General de Agudos San Martín (HIGA) y el Instituto de Diagnóstico de La Plata 36 pacientes mediante esofagectomía mininvasiva (EMI) en posición prona (PP). Resultados: durante el tiempo abdominal se produjo una lesión de vasos coronarios. En el tiempo torácico se registraron dos lesiones pulmonares, una lesión del cayado de vena ácigos y una sección del conducto torácico; además hubo un caso de daño al nervio recurrente y una lesión del bronquio fuente izquierdo durante la linfadenectomía. Al analizar el total de las complicaciones se observó que la mayoría de ellas se presentaron en los primeros 20 casos, mientras que en los 16 siguientes solo se registró una lesión pulmonar (p=0,10). Conclusión: como conclusión podemos decir que la EMI en PP, como ya es sabido, es un procedimiento factible y seguro pero ‒dada su complejidad‒ puede provocar lesiones intraoperatorias graves. Aunque los resultados de nuestra serie no arrojaron diferencias de significancia estadística, la cantidad de eventos adversos durante las operaciones realizadas por el mismo equipo disminuyó sensiblemente en la medida en que se adquirió el entrenamiento suficiente.


Background: Since the initial description of laparoscopic fundoplication in 1991 for the treatment of gastroesophageal reflux disease, different minimally invasive procedures have been developed until nowadays, when esophagectomy is performed using combined thoracoscopy and laparoscopy. Objective: The aim of our study is to analyze the adverse events of minimally invasive esophagectomy in prone position during the learning curve. Material and methods: Between November 2011 and June 2017, 36 patients underwent minimally invasive esophagectomy in prone position in the Hospital Interzonal General de Agudos (HIGA) San Martín and the Instituto de Diagnóstico de La Plata. Results: During the abdominal stage one patient presented coronary vessel injury. The complications occurring in the thoracic stage included lung injury (n =2), azygos arch injury (n = 1), thoracic duct dissection (n = 1), laryngeal recurrent nerve lesion (n = 1) and main stem bronchus injury (n = 1) during lymph node resection. Most of these complications occurred in the first 20 patients, while in the remaining 16 cases only lung injury occurred (p = 0.10) Conclusion: Minimally invasive esophagectomy in prone position is a feasible and safe procedure that can cause serious intraoperative complications due to its complexity. Although the results of our series did not show statistically significant differences, the number of adverse events during surgeries performed by the same team showed an important reduction associated with better training.

ABSTRACT

INTRODUCCIÓN: Las técnicas de sutura básicas se consideran competencias mínimas de un egresado de medicina y son fundamentales en el ejercicio de la medicina general. Actualmente, los estudiantes de la Universidad de Concepción no poseen una instancia formal para adquirir estas competencias. OBJETIVOS: Evaluar la validez de un programa de formación de alumnos monitores de sutura a través de los resultados obtenidos mediante un método de evaluación estandarizado, realizado en estudiantes de pregrado de medicina de la Universidad de Concepción. METODOLOGÍA: Estudio preexperimental antes y después. Se realizó intervención teórico-práctica para seis estudiantes de medicina de distintos semestres cursados, entre los meses de mayo y julio de 2017. Consistió en tres módulos: clases teóricas, práctica en modelo biológico y módulo en pabellón quirúrgico supervisado por subespecialistas. Se evaluó punto de sutura continuo y discontinuo en modelo biológico mediante la escala "The Objective Structured Assessment Of Technical Skills" (OSATS). Se describen y comparan resultados de la escala OSATS antes y después del curso. Se aplicó consentimiento informado. Se utilizó SPSS® para análisis estadístico mediante prueba de Mann-Whitney para variables no paramétricas. Se consideró significativo p < 0,05. RESULTADOS: Todos los participantes mejoraron puntuación en escala OSATS. Los participantes progresaron significativamente sus resultados en las distintas escalas OSATS (5,2 vs 8,8; p < 0,05 y 16,5 vs 27,2; p < 0,05) al comparar resultados pre vs posintervención respectivamente. DISCUSIÓN: Nuestra experiencia demuestra que es posible crear un taller de formación de MS con muy buenos resultados, para estudiantes de medicina, a través de una capacitación trimodal, con clases teóricas, simulación y práctica in vivo. Además, constituye la base de futuras investigaciones que buscan solucionar la inexistencia de un programa formal de enseñanza de técnicas de sutura a los estudiantes de medicina de nuestra facultad.


INTRODUCTION: Suture techniques are considered the minimum of a medical examination and are fundamental in the practice of medicine. Currently, the students of the Universidad de Concepción do not have a formal instance to acquire these competences. AIM: To evaluate the validity of a training program for Suture Instructor (SI) students through the results obtained through a standardized assessment method, carried out in undergraduate students of medicine at the University of Concepción. METHOD: Preexperimental before and after study. A theoretical-practical intervention was carried out for six medical students of different semesters of the career, between the months of May and July 2017. It consisted of three modules: theoretical classes, practice in biological model and module in surgical pavilion supervised by subspecialists. Continuous and interrupted sutures were evaluated in the biological model using the "The Objective Structured Assessment of Technical Skills" (OSATS) scale. Results of the OSATS scale are described and compared before and after the course. Informed consent was applied. SPSS® was used for statistical analysis by Mann-Whitney test for non-parametric variables. It was considered significant p < 0.05. Results: All participants improved score on OSATS scale. The participants progressed significantly their results in the different OSATS scales (5.2 vs 8.8, p < 0.05 and 16.5 vs 27.2, p < 0.05) when comparing pre vs post intervention results respectively. DISCUSSION: Our experience shows that it is possible to create an SI training workshop with excellent results for medical students, through a three phase training program, with theory classes, simulation and "in vivo" practice. It also constitutes the basis of future research that seeks to solve the lack of a formal program of teaching suture techniques to medical students of our university.

ABSTRACT

RESUMEN Objetivo: Evaluar la curva de aprendizaje de la facoemulsificación en residentes de Oftalmología. Métodos: Se realizó un estudio prospectivo, descriptivo de corte longitudinal, de las cirugías de cataratas por facoemulsificación, efectuadas por los residentes de Oftalmología en el Servicio de Microcirugía Ocular, entre junio del año 2014 y enero de 2016, con el objetivo de evaluar la curva de aprendizaje de esta cirugía. Las variables de este estudio incluyeron número de cirugías previas realizadas, paso de la técnica quirúrgica efectuada, parámetros facodinámicos empleados (flujo, vacío, potencia y tiempo total de ultrasonido) y complicaciones transoperatorias. Se estudió una muestra de 81 cirugías que cumplieron los criterios de inclusión. A las variables cualitativas se aplicó la prueba exacta de Fisher. Para definir la relación entre las variables continuas fue empleado un análisis de regresión para la curva de mejor ajuste, las ecuaciones y el coeficiente de determinación de estas. El nivel de significación estadística utilizado fue de p < 0,05. Resultados: Se alcanzó una estabilidad en la cirugía con un promedio de 19 procedimientos, con una disminución significativa de las complicaciones. Conclusiones: Los residentes con un mínimo de 30 cirugías previas son capaces de realizar la cirugía en su totalidad sin complicaciones(AU)


ABSTRACT Objective: Evaluate the phacoemulsification learning curve of ophthalmology residents. Methods: A prospective longitudinal descriptive study was conducted of the phacoemulsification cataract operations performed by ophthalmology residents at the Ocular Microsurgery Service from June 2014 to January 2016, with the purpose of evaluating the learning curve for this type of surgery. The variables analyzed were number of previous operations done, step of the surgical technique performed, phacodynamic parameters used (flow, vacuum, power and total time of ultrasound) and intraoperative complications. The study sample was 81 operations meeting the inclusion criteria. Qualitative variables were analyzed with Fisher's exact test. The relationship between continuous variables was determined by regression analysis for the best-fitting curve, their equations and their coefficient of determination. The statistical significance level used was p< 0.05. Results: Surgical stability was achieved in an average 19 procedures, with a significant decrease in complications. Conclusions: Residents with a minimum 30 previous operations are capable of performing the surgery in its entirety without complications(AU)

ABSTRACT

ABSTRACT Introduction: The success of the robot assisted radical prostatectomy (RARP) procedures depend on a successful team, however the literature focuses on the performance of a console surgeon. The aim of this study was to evaluate surgical outcomes of the surgeons during the learning curve in relation to the bedside assistant's experience level during RARP. Materials and Methods: We retrospectively reviewed two non - laparoscopic, beginner robotic surgeon's cases, and we divided the patients into two groups. The first surgeon completed the operations on 20 patients with a beginner bedside assistant in February - May 2009 (Group-1). The second surgeon completed operations on 16 patients with an experienced (at least 150 cases) bedside assistant in February 2015 - December 2015 (Group-2). The collected data included age, prostate volume, prostate specific antigen (PSA), estimated blood loss, complications and percent of positive surgical margins. In addition, the elapsed time for trocar insertion, robot docking, console surgery, specimen extraction and total anesthesia time were measured separately. Results: There were no significant differences between the groups in terms of age, comorbidity, prostate volume, PSA value, preoperative Gleason score, number of positive cores, postoperative Gleason score, pathological grade, protection rate of neurovascular bundles, surgical margin positivity, postoperative complications, length of hospital stay, or estimated blood loss. The robot docking, trocar placement, console surgery, anesthesia and specimen extraction times were significantly shorter in group 2 than they were in group 1 (17.75 ± 3.53 min vs. 30.20 ± 7.54 min, p ≤ 0.001; 9.63 ± 2.71 min vs. 14.40 ± 4.52 min, p = 0.001; 189.06 ± 27.70 min vs. 244.95 ± 80.58 min, p = 0.01; 230.94 ± 30.83 min vs. 306.75 ± 87.96 min, p = 0.002; 10.19 ± 2.54 min vs. 17.55 ± 8.79 min, p = 0.002; respectively). Conclusion: Although the bedside assistant's experience in RARP does not appear to influence the robotic surgeon's oncological outcomes during the learning curve, it may reduce the potential complications by shortening the total operation time.

ABSTRACT

Introducción: La cirugía laparoscópica ha revolucionado el manejo quirúrgico de los pacientes y ha generado una necesidad de capacitación en el área. El rendimiento en la vida real es lo que permite una determinación global de las competencias en un procedimiento y establece un método de formación. El objetivo de este estudio es describir la evolución en la experiencia quirúrgica de un grupo de residentes de cirugía general. Metodología: Estudio observacional analítico de cohorte retrospectiva en el Hospital Universitario San Ignacio. Incluyó 4191 procedimientos realizados, divididos en 1045 apendicectomías laparoscópicas (AL) y 3146 colecistectomías laparoscópicas (CL), realizadas por un total de 52 residentes entre enero de 2008 y diciembre de 2014. Resultados: Tanto en AL como en CL se observó un aumento en el número de procedimientos anuales. Al comparar los tiempos promedios de AL por año de residencia, se observó una tendencia a la disminución en la mediana a medida que el residente era mayor. Las complicaciones intraoperatorias fueron del 0,77% para AL y del 1,9% para CL. La complicación postoperatoria más frecuente fue infección del sitio operatorio con una mortalidad menor al 0,5%. Conclusión: Los resultados evocan la necesidad de continuar con programas de residencia que proporcionen preparación adecuada en el abordaje laparoscópico, posiblemente con exposición cada vez más temprana a procedimientos mínimamente invasivos.


Introduction: Laparoscopic surgery has revolutionized the surgical management of patients, generating a need for training in the area. The performance in real life is what allows a global determination of the competences in a procedure and establishes a method of training. The objective of this study is to describe the evolution in the surgical experience of a group of residents of general surgery.Methodology: Observational analytical study of a retrospective cohort at the University Hospital San Ignacio. It included 4191 surgical procedures divided in 1045 laparoscopic appendectomies (LA) and 3146 laparoscopic cholecystectomies (LC) performed by a total of 52 residents between January 2008 and December 2014. Results: Both LA and LC showed an increase in the number of annual procedures. When comparing the average times of AL per year of residence, a tendency to decrease in the median was observed, as the resident was older. The intraoperative complications were 0.77% for LA and 1.9% for LC; being the most frequent postoperative complication ISO with mortality <0.5%. Conclusion: The results evoke the need to continue with residency programs that provide adequate preparation in the laparoscopic approach, possibly with increasingly early exposure to minimally invasive procedures.
