ABSTRACT

Resumen Introducción: El traumatismo torácico (TT) es la causa de aproximadamente un cuarto de las muertes por traumatismos. Los pacientes tratados con cirugía por traumatismo torácico (CTT) presentan un amplio espectro de características y pronósticos. Objetivos: Describir características clínicas, indicaciones, temporalidad, morbilidad, mortalidad y las variables asociadas a mortalidad en pacientes con CTT. Materiales y Método: Estudio observacional de pacientes tratados con CTT, período enero-1981 a diciembre-2019. Revisión de protocolos prospectivos de TT y base de datos. Se realizó regresión logística para variables asociadas a mortalidad. Se utilizó SPSS25® con prueba chi-cuadrado para comparar clasificación, tipo de TT y su distribución temporal, considerando significativo p < 0,05. Resultados: En total 808 casos (18,2%) de 4.448 TT requirieron CTT. Fueron hombres 767 (94,9%) y la edad promedio fue 31,5 ± 13,8 años. El traumatismo fue penetrante y por arma blanca en la mayoría de los casos. Fueron politraumatizados 164 (20,3%). La cirugía fue urgente en 474 (58,7%), precoz en 41 (5,0%) y diferida en 293 (36,3%) casos. La mortalidad global fue de 6,7% y fue significativamente mayor en TT contusos, politraumatizados y en cirugía urgente. La mortalidad fue 9,7% en CTT urgente, 4,9% en precoz y 2,0% en diferida (p < 0,001). Se observaron variables independientes asociadas a mortalidad. Conclusión: En nuestra serie, las CTT se realizaron principalmente en hombres jóvenes con TT penetrantes. Correspondieron a un grupo heterogéneo en cuanto a las indicaciones, hallazgos y lesiones intratorácicas y/o asociadas. Múltiples variables demostraron influir significativamente en la mortalidad de los pacientes tratados con CTT.


Background: Thoracic Trauma (TT) is the cause of approximately a quarter of trauma deaths. The patients who undergo Thoracic Trauma Surgery (TTS) present a wide spectrum of characteristics and prognosis. Aim: To describe clinical characteristics, indications, temporality, morbidity, mortality and mortality associated variables in TTS patients. Materials and Method: Observational study of TT hospitalized patients, period January-1981 to December-2019. A review of operation notes and database was done. A logistic regression for mortality associated variables was made. To compare classification, type of TT and its temporal distribution, SPSS25® with chi-square test was used, considering significant p < 0.05. Results: A total of 808 (18.2%) of 4.448 TT patients required TTS, 767 (94.9%) were men with average age: 31.5 ± 13.8. The trauma was penetrating trauma due to a stab in most cases, 164 (20.3%) were polytraumatized. The surgery was urgent in 474 (58.7%), early in 41 (5.0%) and delayed in 293 (36.3%) cases. The global mortality was 6.7% and was significantly higher in the blunt TT, polytrauma, urgent and early surgery patients. Mortality in urgent TTS was 9.7%, early 4.9% and 2.0% in delayed (p < 0.001). Independent variables associated with mortality were observed. Conclusions: In our series, TTS were performed mainly in young men with penetrating TT. The group was heterogeneous regarding surgical indications, findings and intrathoracic or associated injuries. Multiple variables showed to influence significantly on mortality in patients who underwent TTS.

ABSTRACT

Background: Lung cancer is the world's leading cause of cancer death. Aim: To describe the clinical, staging and survival characteristics of lung cancer in a public Chilean regional hospital. Material and Methods: Analysis of a prospective database of a thoracic surgery service, retrieving histologically confirmed lung cancer cases from January 2010 to December 2019 and reviewing their medical records. Cases were re-staged by the TNM-8 system and variables were compared between periods 2010-2014 and 2015-2019. Results: We retrieved 551 lung cancer cases, 333 (60 %) men, with a mean age of 65 years. Distant metastases were found in 72% of cases (excluding lymphatic metastases). Of the non-small cell lung cancers (NSCLC), 50 (10%) cases were in stage I, 18 (4%) in stage II, 81 (16%) in stage III and 347 (70%) in stage IV. Global five-year survival was 18%, 20% for NSCLC, 71% for excised NSCLC, 8% for non-excised NSCLC, 88% for stage I and 92% for subgroup IA. Resective surgery was performed in 81 (14%) cases. When comparing 2010-2014 and 2015-2019 periods, the frequency of resective surgery increased from 7% to 20%. Conclusions: The diagnosis of lung cancer was frequently made in advanced stages. There was a significant increase in early diagnosis and frequency of surgeries with curative intent in the second observation period.

ABSTRACT

Prosthetic valve replacement is the standard treatment for aortic valvulopathy. Due to the structural valve deterioration of biological prosthesis and the anticoagulation requirements of mechanical valves, the repair of aortic valve disease is receiving more attention in recent years. The Ozaki technique consists in the reconstruction of a trileaflet valve using autologous pericardium. We report our first two cases of successful reconstruction of the aortic valve using this technique with 12-month echocardiographic and 24-month clinical follow up.

ABSTRACT

Resumen Introducción: Los traumatismos están entre las diez principales causas de muerte a nivel mundial y son la primera en jóvenes. El traumatismo torácico (TT) está presente en un alto porcentaje de las muertes por traumatismos y es la segunda causa de muerte después del traumatismo encefalocraneano. Objetivos: Analizar las variables asociadas a mortalidad, las causas principales y la distribución temporal de la mortalidad en hospitalizados fallecidos con TT. Materiales y Método: Estudio observacional de hospitalizados con TT, período enero de 1981 a diciembre de 2018. Revisión de protocolos prospectivos de TT y base de datos. Se consignaron las causas de muerte sindromáticas principales y se realizó una regresión logística para variables asociadas a mortalidad. Se utilizó SPSS25® con pruebas chi-cuadrado para comparar clasificación, tipo de TT y su distribución temporal, considerando significativo p < 0,05. Resultados: Total 4.297 TT, mortalidad global de 120 (2,8%) casos. Las principales variables independientes asociadas a mortalidad fueron el deterioro fisiológico al ingreso, el hemotórax masivo y el TT por arma de fuego. La principal causa de muerte fue el shock hipovolémico, con diferencias significativas según tipo de TT en las primeras 4 y 24 horas. En la distribución temporal se observó que las muertes con TT penetrante y aislado fueron más precoces y no se evidenció un nuevo peak en la mortalidad luego de la primera semana. Conclusiones: Se observaron variables independientes asociadas a mortalidad en hospitalizados con TT, siendo el deterioro fisiológico al ingreso el factor más importante. Además, existen diferencias significativas en las causas de muerte y distribución temporal de la mortalidad entre diferentes subgrupos de hospitalizados con TT.


Background: Trauma is one of the ten leading causes of death worldwide and the first among the youth. Thoracic trauma (TT) is present in a high percentage of deaths due to trauma and is the second leading cause of death after traumatic brain injury. Aim: To analyze the mortality associated variables, major causes and temporal distribution of mortality among dead hospitalized patients with TT. Materials and Method: Observational study in hospitalized patients with TT, period January 1981 to December 2018. Review of prospective TT protocols and data base. Major syndromic causes of death were recorded and a logistic regression for variables associated with mortality was made. SPSS25® with chi-quadrat tests was used to compare classification, type of TT and temporal distribution. A p value < 0,05 was considered significant. Results: Total 4.297 TT and global mortality was 120 (2,8%) cases. The main independent variables associated with mortality were the physiological decline upon admission, massive hemothorax and TT by firearms. The leading cause of death was hypovolemic shock, with significant differences according to the type of TT in the first 4 and 24 hours. In the temporal distribution was observed that, the deaths with penetrating and isolated TT were earlier and that there was no second peak of mortality following the first week. Conclusions: Independent variables associated with mortality were observed among hospitalized patients with TT, being physiological deterioration the most important factor. Besides, there are significant differences in the death causes and temporal distribution of mortality among the different subgroups of hospitalized patients with TT.

ABSTRACT

Resumen Introducción: El traumatismo es la primera causa de muerte en adolescentes y la quinta en el adulto mayor. El traumatismo torácico (TT) posee características particulares en diferentes grupos de edad. Objetivos: Analizar características clínicas, índice de gravedad de traumatismo (IGT) y mortalidad en hospitalizados por TT según grupo etario. Materiales y Método: Estudio descriptivo de hospitalizaciones por TT, período enero de 1981 a diciembre de 2018. Revisión de protocolos prospectivos de TT y base de datos. Se definió grupo etario según Organización Mundial de la Salud (Adolescente: 10-19 años; Adulto Joven: 20-44 años; Adulto Maduro 45-59 años; Adulto Mayor: ≥ 60 años). Se comparó clasificación, mecanismo, agente, tratamiento, IGT, Trauma Injury Severity Score (TRISS) y mortalidad del TT según grupo etario. Se utilizó SPSS25® con pruebas chi-cuadrado y ANOVA, considerando significativo p < 0,05. Resultados: Total 4.297 TT. Grupo etario Adolescente: 608 (14,1%); Adulto Joven: 2.544 (59,2%); Adulto Maduro: 601 (14,0%); Adulto Mayor: 544 (12,7%). Se observó disminución progresiva y significativa en TT penetrante, por agresión y del TT por arma blanca desde grupo etario Adolescente hasta Adulto Mayor. En Adulto Joven predominó tratamiento invasivo: cirugía 541 (21,2%) y en Adulto Maduro el TT con lesiones asociadas 215 (35,8%), p < 0,05. Según grupo etario, se observaron diferencias significativas en TRISS y en mortalidad. La mortalidad fue 1,6%; 2,5%; 3,3%; 5,0%, según grupo etario respectivamente (p < 0,05). Conclusiones: Existen diferencias estadísticamente significativas en las características clínicas, IGT y mortalidad del TT al comparar distintos grupos etarios. La edad es uno de los factores que determina el pronóstico de pacientes hospitalizados por TT.


Background: Trauma is the leading death cause among adolescents and the fifth in the elderly. Thoracic trauma (TT) has particular characteristics in different age-groups. Aim: To analyze clinical characteristics, trauma severity indices (TSI) and mortality in patients hospitalized for TT among different age-groups. Materials and Method: Descriptive study of patients hospitalized for TT between January-1981 and December-2018. Prospective TT surgical operation notes and data base were reviewed. Age-groups were determined according to the World Health Organization (Adolescent: 10-19 years; Young Adult: 20-44 years; Mature Adult: 45-59 years; Elderly > 60 years). TT classification, mechanism, agent, treatment, TSI, Trauma Injury Severity Score (TRISS) and mortality were compared among age-groups.

ABSTRACT

Resumen Introducción: El traumatismo penetrante cardíaco (TPC) es una lesión poco frecuente y con alta morbilidad y mortalidad. Objetivo: Analizar la evolución de características clínicas, anatómicas, gravedad, morbilidad y mortalidad de pacientes operados por TPC. Materiales y Métodos: Estudio analítico de pacientes tratados quirúrgicamente por TPC en Hospital Clínico Regional "Dr. Guillermo Grant Benavente", Concepción, Chile. Se analizaron los periodos: enero-1990 a diciembre-2004 y enero-2005 a diciembre-2019. Se comparó: sexo, edad, lesiones asociadas, agente y mecanismo del traumatismo, comportamiento fisiopatológico, ubicación anatómica de la lesión, clasificaciones del traumatismo cardíaco Attar, Saadia y OIS-AAST, IGT (índices de gravedad del traumatismo): ISS, RTS-T y TRISS, morbilidad y mortalidad según periodos. Se realizó análisis estadístico con SPSS25®, se utilizaron las pruebas chi-cuadrado, exacta de Fisher y Mann-Whitney. Se consideró significativo un valor p < 0,05. Resultados: Total 235 TPC, 112 en el primer periodo y 123 en el segundo. Mecanismo arma blanca en 96 (85,7%) y 104 (84,6%) según periodos. En el segundo periodo se observó un aumento de lesiones extratorácicas asociadas, paro cardiorrespiratorio y lesión de ubicación izquierda. Las clasificaciones del traumatismo cardíaco y los IGT ISS, RTS-T y TRISS mostraron mayor gravedad y probabilidad de muerte en los pacientes del segundo periodo. La mortalidad no mostró diferencias: 14 (12,5%) y 14 (11,4%) según periodos (p = 0,792). Discusión: En nuestra serie los pacientes tratados por TPC han evolucionado hacia un perfil de mayor gravedad tanto en parámetros fisiológicos como anatómicos. La mortalidad se ha mantenido estable a través del tiempo.


Background: Penetrating cardiac injury (PCI) is a rare injury with high morbidity and mortality. Aim: To analyze the evolution of clinical and anatomical characteristics, severity, morbidity and mortality of patients operated on by PCI. Materials and Methods: Analytical study of patients surgically treated for PCI at the "Guillermo Grant Benavente" Regional Clinical Hospital, Concepción, Chile. Two periods were analyzed: January-1990 to December-2004 and January-2005 to December-2019. Sex, age, associated injuries, trauma agent and mechanism, pathophysiological behavior, anatomic location of the injury, classifications of cardiac trauma: Attar, Saadia and OIS-AAST, TSI (trauma severity indices): ISS, RTS-T and TRISS, morbidity and mortality were compared according to periods. Statistical analysis was performed with SPSS25®, the chi-square, Fisher exact and Mann-Whitney tests were used. A p value < 0.05 was considered significant. Results: Total 235 PCI, 112 in the first period and 123 in the second. Stab as mechanism in 96 (85.7%) and 104 (84.6%) according to periods. An increase in associated extra thoracic injuries, cardiorespiratory arrest, and injury to the left location were observed in the second period. The cardiac trauma classifications and the TSI ISS, RTS-T and TRISS showed greater severity and probability of death in the second period patients. Mortality did not show differences: 14 (12.5%) and 14 (11.4%) according to periods, p = 0.792. Discussion: In our series, patients treated with PCI have evolved towards a more severity profile in both, physiological and anatomical parameters. Mortality has been stable over time.

Para mortalidad se realizó análisis univariado con cálculo de Odds Ratio. Resultados: Total 4.306 traumatismos torácicos (TT), HMTT 119 (2,8%). Hombres 112 (94,1%), edad promedio 32 ± 13,2 años, 91 (76,5%) pacientes presentaron TT aislado, 28 (23,5%) asociado a lesiones extratorácicas, de estos, 23 (19,3%) fueron politraumatismos. Fueron traumatismos penetrantes 102 (85,7%). El HMTT se atribuyó principalmente a: lesión de pared en 38 (31,9%) y lesión pulmonar en 29 (24,4%). De las cirugías torácicas: 87 (73,1%) fueron urgentes (≤ 4 h), 10 (8,4%) precoces (> 4-24 h) y 22 (18,5%) diferidas (> 24 h). Hospitalización postoperatoria promedio 7,9 ± 6,4 días. Según IGT: ISS promedio 17,4 ± 9,6, RTS-T promedio 10,2 ± 2,7, TRISS promedio 12,7. Morbilidad 46 (38,7%) y mortalidad 15 (12,6%). Discusión: Los HMTT se atribuyeron principalmente a lesiones de pared y lesión pulmonar. En la mayoría se requirió cirugía torácica de urgencia. La mortalidad observada es semejante a la esperada según IGT. Existen variables asociadas a mayor mortalidad.


Introduction: Massive hemothorax (MH) can be defined as the sudden accumulation of ≥ 1500 ml of blood in the pleural cavity or debit ≥ 200 ml/h in 3-4 hours through pleurostomy, and it is considered a serious complication. Aim: To describe features, trauma severity indexes (TSI), morbidity and variables associated with mortality in patients with traumatic MH who required surgical treatment. Materials and Method: analytical longitudinal study. Period January 1981 to December 2018. Database, surgical protocols, medical records review. Description of MH characteristics. The following TSI were calculated: Injury Severity Score (ISS), Revised Trauma Score (RTS-T), Trauma Injury Severity Score (TRISS). An Odds Ratio univariate analysis was used for mortality. Results: Total 4306 TT, operated MH 119 (2.8%). Men were 112 (94.1%), average age 32 ± 13.2 years, 91 (76.5%) had isolated TT, 28 (23.5%) were associated with extrathoracic injuries and of these 23 (19.3%) were polytraumatized patients. Penetrating TT was 102 (85.7%). MH was mainly attributed to: chest wall injury in 38 (31.9%), pulmonary lacerations 29 (24.4%). Of the thoracic surgeries: 87 (73.1%) were urgent (≤ 4 h), 10 (8.4%) early (> 4-24 h) and 22 (18.5%) deferred (> 24 h). Average post operatory stay (days): 7.9 ± 6.4 According to TSI: average ISS 17.4 ± 9.6; RTS-T average 10.2 ± 2.7; TRISS average 12.7. Morbidity 46 (38.7%). Mortality 15 (12.6%). Discussion: MH is mainly attributed to chest wall injuries and pulmonary lacerations. Most of HM required urgent thoracic surgery. The observed mortality is similar to that expected one by TSI. There are variables associated with higher mortality in MH.

ABSTRACT

Background: Lungs are the second location in frequency of hydatidosis or cystic echinococcosis. Aim: To characterize the clinical manifestations, diagnosis, findings and treatment of patients hospitalized for a pulmonary hydatid cyst (PHC). Materials and Methods: Review of databases, medical records, operation notes and death certificates of patients admitted to a Chilean regional hospital with a PHC. Results: Four hundred twenty-nine cases were identified and complete data was obtained from 368 patients aged 34 ± 19 years, 224 (60,9%)men. The most common clinical manifestations were cough in 269 (73%) and chest pain in 217 (59%). The most frequent locations were the right lung in 210 (57%) and lower lobes in 218 (59%). One hundred eighty-seven cysts (51%) were complicated. Conservative surgery (cystectomy) was performed in 308 (84%). Postoperative morbidity was observed in 77 (21%) and mortality in 6 (2%) patients. Recurrence was observed in 28 (8%) patients. There was a significant reduction in morbidity, mortality, reoperations, and postoperative days over time. Conclusions: In these patients, pulmonary hydatidosis was diagnosed mainly during working ages and half of patients had a complicated cyst.

ABSTRACT

Background: Primary cardiac tumors have a low incidence, and their presentation form and clinical course are not well known. Aim: To describe the characteristics, treatment, follow up and survival of patients with primary cardiac tumors (PCT). Material and Methods: Review of all surgical procedures for PCT performed between 1984 and 2019 in a regional general hospital. The information was obtained from surgical protocols, surgical and pathology databases, medical records and registries of the Chilean National Identification Service. The clinical features of patients, immediate and long term outcomes are described. Results: Seventy-two surgical procedures for PCT were reviewed. Patients' age was 55 ± 15 years and 60% were women. The most common histological types were myxoma in 49 patients (68%), papillary fibroelastoma in 13 (18%) and sarcoma in 6 (8.3%). Forty-nine (68.1%) were symptomatic and all tumors were found on echocardiography. Fifty-one (71%) were in the left atrium, 10 (14%) in the aortic valve and eight (11%) in the right atrium. The surgical procedures were tumor resection in 48 patients (67%) and resection and repair with patch in 23 (32%). Mean postoperative stay was 6.6 ± 4.4 days, eight patients (11%) had complications and no patient died in the immediate postoperative period. Long term survival was higher in patients with benign PCT as compared with those with malignant tumors. Conclusions: Most PCTs in this group of patients were benign neoplasms and the most common tumors were myxomas. The main diagnostic method is echocardiography and the prognosis of surgical treatment is excellent when the tumors are benign. (Rev Med Chile 2020; 148: 327-335)

ABSTRACT

Resumen Objetivo: Nuestro objetivo es comparar la efectividad de la tutoría impartida por pares de 6° versus 14° semestre en la adquisición de habilidades procedimentales básicas en estudiantes de medicina. Materiales y Método: Estudio cuasi-experimental, antes y después. La intervención consta inicialmente de un curso de formación de monitores de sutura (MS) para dos estudiantes de 6° y dos de 14° semestre de medicina. Posteriormente se implementó un taller de sutura tutorizado por MS a 23 estudiantes de 8° semestre de medicina. Se evaluó sutura continua y discontinua mediante el instrumento: "The Objective Structured Assessment Of Technical Skills" (OSATS) y satisfacción mediante encuesta tipo Likert validada por expertos. Se describen y comparan los resultados pre y postintervención y satisfacción de los estudiantes, de acuerdo al semestre cursado del MS. Se aplicó consentimiento informado. Se utilizó SPSS24® para análisis estadístico mediante prueba de Mann Whitney. Se consideró significativo p < 0,05. Resultados: Ambos grupos progresaron significativamente en la escala OSATS, grupo tutorizado por MS de 6° semestre: 18,1 vs 28,1 (p < 0,001) y grupo tutorizado por MS de 14° semestre: 15,5 vs 27,8 (p < 0,001). Los puntajes finales no presentan diferencias significativas. La intervención fue evaluada con 66 de 68 puntos, sin diferencias significativas según el semestre cursado del MS. Conclusión: Nuestra experiencia muestra que es posible utilizar la tutoría por pares entrenados para la enseñanza de habilidades quirúrgicas, independientemente si la tutoría es impartida por pares de cursos inferiores o superiores, logrando un progreso significativo y un desempeño procedimental equivalente, además de una alta satisfacción entre los estudiantes.


Aim: Our objective is to compare the effectiveness of tutoring taught by 6th versus 14th semester peer students in the acquisition of basic procedural skills in medical students. Materials and Method: Quasi experimental study, before and after. The intervention initially consists of a training workshop for suture monitors (SM) for two students of 6th and two students of 14th semester of medicine. Subsequently, a suture workshop taught by SM to 23 fourth-year medical students was implemented. Continuous and discontinuous suture was evaluated using the instrument: "Objective structured evaluation of technical skills" (OSATS) and satisfaction through a survey validated by experts. The results of pre and post intervention and student satisfaction are described and compared, according to the semester attended by the SM. Informed consent was applied. Excel® and SPSS24® were used for statistical analysis by Mann Whitney test. It was considered significant p < 0.05. Results: Both groups progressed significantly on the OSATS scale, group tutored by 6° semester SM: 18.1 vs 28,1 (p < 0.001) and group tutored by 14° semester SM: 15.5 vs 27,8 and (p < 0.001). The final scores did not they present significant differences. The intervention was well evaluated with 66 out of 68 points, without significant differences according to the semester coursed of the SM. Conclusion: Our experience shows that it is possible to use peer tutoring by trained tutors to teach surgical skills, regardless of whether the teaching is given by pairs of lower or higher courses, achieving significant progress and equivalent procedural performance, in addition to high satisfaction among students.

RESULTADOS: Total 4.163 pacientes hospitalizados por TT, 1.719 (41,3%) TTC. Hombres 1.327 (77,2%), edad promedio 46,7±18,8 años. Se consideró TT aislado 966 (56,2%), asociado a lesiones extratorácicas 753 (43,8%) y de estos 508 (29,6%) eran politraumatizados. Mecanismo: Accidente de tránsito 838 (48,7%), caída de altura 279 (16,2%). Lesiones y hallazgos torácicos: fractura costal 1.294 (75,3%), neumotórax 752 (43,1%). Tratamiento: médico 874 (50,8%), pleurotomía 704 (41%) y cirugía torácica 141 (8,2%). Período de hospitalización 9,2 ± 9,5 días. Según IGT: ISS promedio 14,1 ± 11,1, RTS-Tpromedio 11,5 ± 1,5, TRISS promedio 6,6. Morbilidad en 297 (17,3%), mortalidad en 68 (4%). DISCUSIÓN: La causa principal de los TTC fue el accidente de tránsito. La fractura costal correspondió a la lesión torácica más frecuente. La mayoría requirió solo tratamiento médico. La mortalidad fue menor a la esperada según IGT.


BACKGROUND: Thoracic trauma (TT) is a major cause of morbimortality, involved in 25-50% of trauma deaths. Internationally, blunt thoracic trauma (BTT) is the most frequent type of TT. OBJECTIVE: Our objectives are to describe the clinical characteristics, treatments, morbidity and mortality in patients hospitalized by blunt thoracic trauma (BTT) in our institution. MATERIAL AND METHODS: Cross-sectional descriptive study from january-1981 to december-2017. Prospective database review, surgical protocols and clinical files. The characteristics of the BTT are described and compared. The following trauma severity indices (TSI) were calculated: Injury Severity Score (ISS), Revised Trauma Score (RTS-T) and Trauma Injury Severity Score (TRISS). RESULTS: 4,163 patients were hospitalized because of TT, 1.719 (41.3%) of them with BTT. 1,327 (77.2%)patients were men, average age 46.7 ± 18.8 years-old. We considered isolated TT 966 (56.2%), associated with extrathoracic lesions 753 (43,8%) and 508 (29.6%)with polytraumatism. Mechanism: Traffic accident 838 (48.7%), fall down from a height 279 (16.2%). Lesions and intrathoracic findings: rib fracture 1.294 (75.3%), pneumothorax 752 (43.7%). Treatment: Medical 876 (50.8%), pleurotomy 704 (41%) and thoracic surgery 141 (8.2%). Average hospitalized period 9.2 ± 9.5 days. According to TSI: ISS average 14.1 ± 11.1, RTS-T average 11.5 ± 1.5, TRISS average 6.6. Morbidity in 297 (17.3%), mortality in 68 (4%). DISCUSSION: The TTC was mainly attributed to the traffic accident. Rib fracture was the most common chest injury. The majority of patients required only medical treatment. Mortality was lower than expected according to TSI.

ABSTRACT

INTRODUCCIÓN: El quiste hidatídico cardiaco es una patología infrecuente, producida por la llegada de Equinococcus granulosus a la circulación coronaria. MATERIALES Y MÉTODO: Hombre de 52 años, con antecedente de quiste hidatídico cardiaco operado hace 27 años, insuficiencia cardiaca y enfermedad coronaria. Presentó disnea progresiva de un año de evolución. Estudio con radiografía de tórax, ecocardiografía y tomografía computada que mostró imagen compatible con hidatidosis cardiaca recidivada en el ventrículo izquierdo, arteria pulmonar e hilio pulmonar izquierdo, rodeando por completo el tronco coronario común izquierdo y parte proximal de la arteria descendente anterior. Se constató fracción de eyección de ventrículo izquierdo aproximadamente de 30%. No se encontró evidencia de enfermedad hidatídica extracardiaca. Se decidió tratamiento quirúrgico. Se abordó por esternotomía media y en circulación extracorpórea, se observaron lesiones compatibles con quiste hidatídico multiloculado de ubicación miocárdica en ventrículo izquierdo, con incontables vesículas hijas. Se realizó quistectomía más periquistectomía hidatídica sin incidentes. Presentó hemorragia postoperatoria por lo que requirió reintervención quirúrgica precoz. Evolucionó favorablemente y fue dado de alta sin complicaciones. A seis años de seguimiento se encuentra asintomático, sin evidencia tomográfica y ecocardiográfica de recidiva. DISCUSIÓN: La hidatidosis es una zoonosis endémica en Chile. La ubicación cardiaca es infrecuente, correspondiendo al 0,5 al 2% de los casos. Suele asociarse a la presencia de quistes extracardiacos. La ubicación más frecuente es la pared libre del ventrículo izquierdo a nivel intramiocárdico. El tratamiento médico suele ser insuficiente, por lo que se recomienda la resección quirúrgica.


INTRODUCTION: Cardiac hydatid cyst is a rare disease caused by Echinococcus granulosus arrival of the coronary circulation. MATERIAL AND METHOD: 52 years old man with a history of cardiac hydatid cyst operated 27 years ago, heart failure and coronary artery disease. He presented with a history of one year of progressive dyspnoea. Study with chest radiography, echocardiography and computed tomography showed an image compatible with cardiac hydatid disease recurrence in relation to the left ventricle, pulmonary artery and anterior descending artery. Ejection fraction of the left ventricle was approximately 30%. No evidence of extracardiac hydatid disease was found and surgical treatment was decided. Addressed by median sternotomy and extracorporeal circulation, a multiloculated myocardial hydatid cyst, with hundreds of daughter vesicles of different size was found. Pericystectomy of the hydatid cyst was performed without incident. The patient presented postoperative bleeding which required early reoperation. Posteriorly, was discharged without complications. DISCUSSION: Hydatid disease is an endemic zoonosis in Chile. Heart location is infrecuent and correspond to 0.5 to 2% of the cases, usually associated with the presence of extracardiac cysts. The most common location is the free wall of the left ventricle at intramyocardial level. Medical treatment is often inadequate and surgical resection is recommended.

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

Embolic stroke secondary to cardiac tumors is uncommon. However, 25-30% of cardiac tumors may cause systemic emboli. We report a 29-year-old male consulting for a sudden episode of aphasia and right hemiparesis, compatible with infarct of the left middle cerebral artery territory. Transthoracic echocardiography reported an ovoid tumor of 8 × 7 × 7 mm in relation to the sub valvular apparatus of the mitral valve. After neurologic stabilization, surgical treatment was performed. Approached by median sternotomy and in cardiopulmonary bypass, the mitral valve was explored. A macroscopic tumor consistent with a papillary fibroelastoma curled in sub valvular chordae was found. It was deployed and resected from its base, while the anterior mitral leaflet was preserved intact. Histopathological examination confirmed the intraoperative macroscopic diagnosis. The patient recovered uneventfully postoperatively and was discharged on the fifth day after surgery. He currently is in functional capacity I without cardiovascular symptoms at five years follow-up.
