RESUMEN
Objective: Thoracic outlet syndrome (TOS) comprises a series of signs and symptoms produced by compression of neurovascular structures in any of the anatomical spaces of the thoracic outlet. First rib resection is a therapeutic alternative to decompress the structures of the thoracic outlet at the costoclavicular space. Traditional surgical approaches include transaxillary, supraclavicular, and infraclavicular access. The objective was to describe the surgical experience and follow up results of first rib resection using video assisted thoracoscopic surgery (VATS) in patients with vascular TOS. Methods: Observational descriptive study based on a retrospective single centre analysis of a prospective database. Patients diagnosed with vascular TOS who underwent VATS first rib resection from January 2017 to December 2023 were included. The diagnosis for each subtype was based on the criteria defined in the standards of the American Society for Vascular Surgery in TOS. Among other things, the response to initial anticoagulation, peri-operative data, complications, symptom improvement, duration of post-operative anticoagulation, and symptom recurrence were investigated. Results: Twenty nine patients diagnosed with vascular TOS who underwent VATS first rib resection, three of whom had bilateral procedures, were included. The total number of costal rib resections performed was 32 (31 venous TOS and one arterial TOS). The mean age was 29.1 ± 10.4 years and mean hospital stay was 2.7 ± 1.2 days. There were neither conversions to open surgery nor intra-operative complications, but there were two major post-operative complications (6.25%). No recurrences were detected during midterm follow up (median of 17.9 months, interquartile range 7.3, 45). Conclusion: VATS first rib resection is a safe and feasible procedure. Unlike traditional approaches, this procedure allows physicians to make the resection under complete vision of the anatomical structures of the thoracic outlet reducing intra-operative complications and, if necessary, entire rib resection can be performed.
RESUMEN
Purpose: To investigate the profile of hospital admissions for sympathectomies performed in the Brazilian Unified Health System (SUS), comparing open and video-assisted techniques. Methods: Data on sympathectomies were collected from the SUS Department of Informatics (DATASUS), recorded between 2014 and 2023. The data were tabulated, and descriptive statistics and correlation analyses were performed. Results: There was reduction in the number of admissions for all sympathectomies during the analyzed period. The use of video-assisted surgeries was higher than that of open surgeries for thoracic procedures, but lower for lumbar procedures. The costs of hospital admission for the procedures were similar, although the length of stay and mortality associated with open surgeries were higher, both in thoracic and lumbar sympathectomies. Conclusions: The collected data were not individualized, preventing follow-up. Additionally, the study did not account for procedures performed in the private healthcare system. Despite its limitations, this study provides an overview of sympathectomies in Brazil, indicating that, although open sympathectomies are potentially more disadvantageous, they are still widely performed, especially for lumbar procedures.

Several technical variations of tympanoplasty have been reported, usually involving the type of graft and/or instruments used. Few studies have focused on the outcome of type-1 tympanoplasty specifically in teaching scenarios. We aimed to describe the results of type-1 tympanoplasty performed by residents, and to investigate potential predictive factors of surgical success. To do so, we did a retrospective analysis of medical records of patients who underwent type-1 tympanoplasty in a tertiary university hospital. We evaluated the tympanic membrane closure and audiometric outcomes during the first year of follow-up, and compared the results according to some clinical and surgical factors. 130 operated ears were included in the study. The closure rate reached 84.12% after one month and 72.72% after twelve months of surgery. The mean air-bone gap was 22.98 dB preoperatively, and reached 10.55 dB after surgery. Perforation closure rates were 85% and 57.14% for those operated by endoscopic and microscopic-assisted approaches, respectively (p = 0.004). The use of cartilage grafts and time without otorrhea of more than three months prior to surgery were also predictors of surgical success (p = 0.002 and 0.041, respectively). Gender, age, perforation size, contralateral disease, operated side, reoperation, and degree of hearing loss did not significantly interfere with outcomes. Tympanoplasty showed good overall results when performed by residents, although inferior to those reported by experienced surgeons. The use of the endoscope, cartilage grafting, and longer preoperative time without otorrhea were predictors of surgical success in this scenario. Level of evidence: IIB.
RESUMEN
Cholelithiasis has a major impact on global health and affects an average of 20% of the Western population. The main risk factors are females, age over 40 years, obesity and pregnancy. Most of the time it is asymptomatic, but when there are symptoms, they are generally nonspecific. Bile was considered sterile, but today it is known that it contains a complex bacterial flora, which causes biofilm in the gallbladder and gallstones. Among the main bacteria associated with cholelithiasis are Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, species of Enterococcus spp. and Acinetobacter spp. Antibiotic prophylaxis is used in an attempt to reduce postoperative infections, especially at the surgical site. However, some authors found no relationship between the use of antibiotic prophylaxis and a lower risk of surgical site infection. Thus, the aim of this double-blind randomized clinical trial was to compare the existence or not of bacteriobilia in patients at low anesthetic risk who underwent videolaparoscopic cholecystectomy, and its correlation with the use of prophylactic antibiotics. This study included 40 patients between 18 and 65 years old, diagnosed with cholelithiasis, symptomatic or not, with low anesthetic risk classified by the American Society of Anesthesiology in ASA I or ASA II, without complications or previous manipulation of the bile duct, who underwent elective video cholecystectomy, divided into two groups: Experimental Group A (n = 20), which received 2 g of Cephalotin (first-generation Cephalosporin, Keflin®, ABL antibiotics, Cosmópolis, Brazil) during anesthetic induction, and Control Group B (n = 20), where no antibiotics were administered until bile collection. After the procedure, a bile sample was collected and culture and antibiogram were performed. In the sample, 22 (55%) were classified as ASA I and 18 (45%) as ASA II. It was observed that 81.8% of the patients who had a positive culture did not use antibiotics, against 18.2% of those who used prophylaxis. When comparing patients regarding anesthetic risk, ASA I patients had a positive culture in 9.1% of cases, against 90.9% in patients classified as ASA II. It was concluded that patients with higher anesthetic risk (ASA II) have a higher chance of bacteriobilia and benefit from antibiotic prophylaxis when compared to patients with lower anesthetic risk (ASA I).
RESUMEN
ABSTRACT The ideal ventral hernia surgical repair is still in discussion1. The defect closure with a mesh-based repair is the base of surgical repair, in open or minimally invasive techniques2. The open methods lead to a higher surgical site infections incidence, meanwhile, the laparoscopic IPOM (intraperitoneal onlay mesh) increases the risk of intestinal lesions, adhesions, and bowel obstruction, in addition to requiring double mesh and fixation products which increase its costs and could worsen the post-operative pain3-5. The eTEP (extended/enhanced view totally intraperitoneal) technique has also arisen as a good option for this hernia repair. To avoid the disadvantages found in classic open and laparoscopic techniques, the MILOS (Endoscopically Assisted Mini or Less Open Sublay Repair) concept, created by W. Reinpold et al. in 2009, 3 years after eTEP conceptualization, allows the usage of bigger meshes through a small skin incision and laparoscopic retro-rectus space dissection, as the 2016 modification, avoiding an intraperitoneal mesh placement6,7. This new technique has been called E-MILOS (Endoscopic Mini or Less Open Sublay Repair)8. The aim of this paper is to report the E-MILOS techniques primary experience Brazil, in Santa Casa de Misericórdia de São Paulo.
RESUMO O tratamento cirúrgico ideal para correção das hérnias ventrais ainda é motivo de grande discussão1. O fechamento do defeito associado a utilização de telas para reforço da parede abdominal são passos fundamentais da terapia cirúrgica, podendo ser realizados tanto pela via aberta quanto pelas técnicas minimamente invasivas2. A via aberta apresenta maiores taxas de infecção de sítio cirúrgico, enquanto o reparo laparoscópico IPOM (intraperitoneal onlay mesh) acarreta um risco aumentado de lesões intestinais, aderências e obstruções intestinais, além de requerer uso de telas de dupla face e dispositivos de fixação que encarecem o procedimento e não raro aumentam a dor no pós-operatório3-5. A técnica eTEP (extended/enhanced view totally extraperitoneal), tem ganhado importância, mostrando-se uma boa opção para a correção das hérnias ventrais também2. A fim de se evitar as desvantagens das técnicas abertas e laparoscópicas "clássicas" o conceito MILOS (Endoscopically Assisted Mini or Less Open Sublay Repair), desenvolvido por W. Reinpold et al. em 2009, 3 anos antes do advento do eTEP, possibilita ao cirurgião o uso de telas de grandes dimensões no plano retromuscular através de uma pequena incisão na pele e dissecção laparoscópica deste espaço, conforme modificação realizada em 2016, evitando a colocação de uma tela no espaço intraperitoneal6-7. Esta nova técnica passou a se chamar EMILOS (Endoscopic Mini or Less Open Sublay Repair)8 Este artigo tem como objetivo relatar nossa experiência inicial no emprego da técnica E-MILOS no Brasil, na Santa Casa de Misericórdia de São Paulo.
RESUMEN
O objetivo deste estudo foi identificar o melhor acesso laparoscópico para visualização e manipulação das estruturas umbilicais no interior da cavidade abdominal de fetos bovinos. Foram utilizados nove fetos de bezerros de vacas no terço final da gestação, todos submetidos à laparoscopia com dois portais de acesso, primeiro no flanco direito e depois na região ventral do abdômen, onde foram verificadas as possibilidades de acesso às estruturas umbilicais. Em ambas as abordagens, os portais de acesso permitiram visualizar e manipular as estruturas de interesse, mas a abordagem lateral foi mais eficaz com melhor visualização e manipulação. Os acessos ventrais não proporcionavam a mesma facilidade de visualização e manipulação, pois as estruturas umbilicais fixadas na parede abdominal ficavam muito próximas aos portais. Esses resultados demonstram que a laparoscopia pode ser utilizada para manipulação e visualização das estruturas umbilicais, sendo a abordagem lateral mais eficaz.

El síndrome de banda amniótica (SBA) o complejo de disrupción de banda amniótica es aquella malformación congénita que ocurre como consecuencia de bridas amnióticas de etiología heterogénea, patogénesis que involucra una serie de manifestaciones clínicas fetales, tales como constricción, amputación y múltiples defectos craneofaciales, viscerales y de la pared del cuerpo. La prevalencia estimada de SBA oscila entre 1:15,000 y 1:1,200 nacidos vivos. Afecta a ambos sexos por igual. El diagnóstico prenatal puede sospecharse tan pronto como el primer trimestre tardío, cuando las imágenes por ultrasonido detectan anillos de constricción, amputaciones de extremidades y/o defectos craneofaciales. La terapia prenatal puede ofrecer una alternativa de tratamiento con la liberación de anillos de constricción bajo fetoscopia en aquellos fetos que se verían beneficiados con el procedimiento.
Amniotic band syndrome (ABS) or amniotic band disruption complex is a congenital malformation that occurs because of amniotic flanges of heterogeneous etiology, a pathogenesis that involves a series of fetal clinical manifestations, such as constriction, amputation, and multiple craniofacial, visceral and wall defects. The estimated prevalence of ABS ranges from 1:15.000 to 1:1.200 liveborn. It affects both sexes equally. Prenatal diagnosis may be suspected as early as the late first trimester when ultrasound imaging detects constriction rings, limb amputations and/or craniofacial defects. Prenatal therapy may offer an alternative treatment with release of constriction rings through fetoscopy in those fetuses that would benefit from the procedure.
RESUMEN
Resumen: Introducción: La cirugía torácica videoasistida es hoy un procedimiento aceptado por ser seguro, factible y efectivo para el tratamiento de casi todas las enfermedades del tórax. En el 2010 se comienzan a publicar procedimientos complejos por un solo puerto, con una gran expansión a nivel mundial. Esta vía de abordaje es al menos equiparable a la multiportal en lo que concierne a resultados en el postoperatorio, o incluso mejor en lo referente a dolor, neuralgia intercostal y estadía hospitalaria. Realizamos un análisis retrospectivo de los procedimientos uniportales entre septiembre de 2018 y agosto de 2020. Resultados: 40 pacientes fueron sometidos a procedimientos por vía uniportal torácica. De estos, 18 pacientes fueron sometidos a resecciones anatómicas (45%), 19 a resecciones atípicas (no anatómicas), una timectomía y dos biopsias pleurales. Se realizaron 12 lobectomías (30%), 3 neumonectomías (7,5%) y 3 segmentectomías (7,5%). Se convirtieron a cirugía abierta 6 pacientes (15%) y falleció un paciente por sepsis respiratoria. En cuanto a las complicaciones tuvimos en las resecciones anatómicas ocho complicaciones (cinco mayores), en las no anatómicas 4 complicaciones (2 mayores). Del postoperatorio un paciente con dolor de más de un mes de evolución, uno con parestesias en el territorio intercostal y dos con disnea. Las resecciones anatómicas tuvieron una media de internación de 8 días y 5.8 días de drenaje pleural, mientras que las no anatómicas 5,5 días de internación y 3.3 días de drenaje pleural. Conclusión: la cirugía uniportal es segura y practicable en centro de bajo volumen.
Abstract: Introduction: video assisted thoracic surgery is widely accepted today as a safe, feasible and effective procedure to treat almost all thoracic conditions. In 2010, uniportal complex procedures begin to appear in scientific publications around the world, evidencing major expansion. This surgical approach is at least comparable to the multiportal approach in terms of postoperative results or even in regards to pain, intercostal neuralgia and length of hospital stay. We performed a retrospective study of uniportal procedures between September 2018 and August 2020. Results: 40 patients underwent uniportal thoracic surgeries. 18 of these were subject to anatomic resections (45%), 19 to atypical resection (non-anatomic), one thymectomy and two pleural biopsies, 12 lobectomies (30%), 3 neumomectomies (7,5%) and 3 segmentomectomies (7,5%). In 6 patients the procedure was converted to an open surgery (15%) and one patient died for respiratory sepsis. As to the occurrence of complications, 8 complications were seen in anatomic resections (5 major complications) and 4 complications in non-anatomic resections (2 major complications). One patient reported pain that lasted over one week in the postoperative stage, another one referred paresthesia and two reported dyspnea. Length of stay in the hospital was 8 days in anatomic resections and 5.8 days of pleural drainage, whereas in non-anatomic resections it was 5.5 and 3.3 respectively. Conclusion: uniportal surgery is safe and feasible in a relatively small health center.
Resumo: Introdução: a cirurgia torácica videoassistida é hoje um procedimento aceito por ser seguro, viável e eficaz para o tratamento de quase todas as doenças torácicas. Em 2010, começaram a ser publicados procedimentos complexos por porta única com grande expansão mundial. Essa abordagem é pelo menos comparável à abordagem multiporta em termos de resultados pós-operatórios ou ainda melhor em termos de dor, neuralgia intercostal e internação hospitalar. Realizamos uma análise retrospectiva dos procedimentos uniportais entre setembro de 2018 e agosto de 2020. Resultados: 40 pacientes foram submetidos a procedimentos por via torácica uniportal. Destes, 18 pacientes foram submetidos a ressecções anatômicas (45%), 19 foram submetidos a ressecções atípicas (não anatômicas), uma timectomia e duas biópsias pleurais. Foram realizadas 12 lobectomias (30%), 3 pneumectomias (7,5%) e 3 segmentectomias (7,5%). Seis pacientes (15%) foram convertidos para cirurgia aberta e um paciente morreu de sepse respiratória. Em relação às complicações, tivemos 8 complicações (5 maiores) nas ressecções anatômicas, 4 complicações (2 maiores) nas ressecções não anatômicas. No pós-operatório, um paciente com dor há mais de um mês de evolução, um com parestesia em território intercostal e dois com dispneia. As ressecções anatômicas tiveram internação média de 8 dias e 5,8 dias de drenagem pleural, enquanto as não anatômicas tiveram 5,5 dias de internação e 3,3 dias de drenagem pleural. Conclusão: a cirurgia uniportal é segura e praticável em um centro de baixo volume.

RESUMEN
RESUMEN Fundamento: la colangiografía videolaparoscópica se ha convertido en un método diagnóstico y terapéutico en la coledocolitiasis. Objetivos: evaluar el valor de la colangiografía transcística en pacientes con sospecha de coledocolitiasis. Métodos: se realizó un estudio de tipo analítico para interpretar y verificar resultado con el objetivo de analizar la correspondencia entre sospecha de coledocolitiasis y resultado de la colangiografía transcística videolaparoscópica, en el Hospital Militar Clínico Quirúrgico Docente Octavio de la Concepción de la Pedraja, desde abril de 2012 hasta diciembre de 2018. La muestra estuvo compuesta por 62 pacientes con sospecha de coledocolitiasis. Resultados: en el estudio, predominó la sospecha moderada de coledocolitiasis en el sexo femenino a expensas de los estudios ecográficos y de laboratorio, específicamente el aumento en el valor de la fosfatasa alcalina y la dilatación del conducto biliar común entre 8 y 10 mm. Los resultados más frecuentes del proceder fueron; el conducto biliar principal sin alteraciones y adherencias vesiculares. El proceder se extendió por más de 60 minutos en más de la mitad de los casos. La estadía en el hospital después del procedimiento fue menos de tres días y prevaleció un excelente resultado. Conclusiones: las mujeres poseen un índice mayor de sospecha de coledocolitiasis y en un rango moderado. Los criterios de laboratorios y ecográficos prevalecen en estos pacientes, sin embargo, no son específicos de coledocolitiasis. La vía biliar principal sin alteraciones y las adherencias vesiculares son los resultados más frecuentes durante el proceder. El tiempo quirúrgico promedio en este proceder es mayor a 60 minutos. La estadía hospitalaria después del proceder es por lo general menor de tres días. El resultado final con este proceder fue excelente.
ABSTRACT Background: videolaparoscopic cholangiography has become a diagnostic and therapeutic method in choledocholithiasis. Objective: to evaluate the value of transcystic cholangiography in patients with suspected choledocholithiasis. Methods: an analytical study was carried out to interpret and verify the result with the objective of analyzing the correspondence between suspected choledocolithiasis and the result of translastic videolaparoscopic cholangiography, at the Octavio Teaching Surgical Clinical Military Hospital of La Concepción de la Pedraja, since April, 2012 to December, 2018. The sample consisted of 62 patients with suspected choledocolithiasis. Results: in the study, moderate suspicion of choledocholithiasis prevailed in the female sex at the expense of ultrasound and laboratory studies, specifically the increase in the value of alkaline phosphatase and dilation of the common bile duct between 8 and 10 millimeters. The most frequent results of the procedure were; the main bile duct without alterations and vesicular adhesions. The procedure extended for more than 60 minutes in more than half of the cases. The hospital stay after the procedure was less than three days and an excellent result prevailed. Conclusions: women have a higher index of suspicion of choledocholithiasis and in a moderate range. Laboratory and ultrasound criteria prevail in these patients, however, they are not specific to choledocholithiasis. The main bile duct without alterations and vesicular adhesions are the most frequent results during the procedure. The average surgical time in this procedure is more than 60 minutes. The hospital stay after proceeding is usually less than three days. The final result with this procedure is excellent.
RESUMEN
BACKGROUND: Surgical scars are a significant cosmetic problem, especially when in exposed areas such as the anterior neck. To avoid or reduce visible scarring, diverse innovative surgical approaches to the neck have been introduced. The purpose of this study was to evaluate the feasibility and safety of the endoscopic resection using the retroauricular approach for submandibular gland excision. METHODS: The present study enrolled 48 patients who underwent conventional transcervical submandibular gland excision and 23 patients who underwent endoscope-assisted retroauricular approach submandibular gland excision, from February 2014 through February 2018 at the Department of Head and Neck Surgery and Otorhinolaryngology of the AC Camargo Cancer Center, in Sao Paulo, Brazil. The surgical outcomes were retrospectively reviewed. RESULTS: In the conventional group, 26 (54%) patients were male. The mean age was 49.3 years (range 22-81). Twenty-two patients (46%) had sialoadenitis; twenty-one (44%) had benign and five (10%) had malignant tumors. The mean total surgical time was 86.4 min (range 40-180), and the mean total length of hospital stay was 1.3 days. Twenty-seven (56%) patients suffered from local postoperative complications in the neck. In the retroauricular group, 14 (61%) patients were male. The mean age was 44.1 years (range 24-71 years). Seven patients (31%) had sialoadenitis, twelve (53%) had benign tumors and four (16%) had malignant tumors. The mean total surgical time was 86.4 min (range 75-300 min), and the mean total length of hospital stay was 1.2 days. Twelve (53%) patients suffered from local postoperative complications in the neck. No surgical site infections or systemic complications were described. CONCLUSIONS: The retroauricular endoscopic-assisted submandibular gland resection is feasible, with excellent cosmetic results and no significant complication rate increase, and can be a safe potential surgical alternative for patients who are motivated to avoid a visible neck scar.

SUMMARY OBJECTIVE The aim of the current study was to compare the efficacy of two different techniques for blocking chest nerves during video-assisted thoracic surgery (VATS) under spontaneous-ventilating anesthesia. METHODS One hundred patients were recruited in this study and divided into two groups. The first, P group, underwent the TPVB approach; the second, I group, underwent the ICNB approach. Then, the rate of clinical efficacy, duration of the block procedure, and its complications were recorded for comparison of the effect of the two approaches. RESULTS No difference was found in the clinical effect of chest nerve blocks between the two groups. Two patients in the ICNB group were converted to general anesthesia due to severe mediastinal flutter (grade three). The number of patients who had grade one mediastinal flutter in the TPVB group was significantly higher than in the ICNB group. Vascular puncture was detected in four patients in the ICNB group and in one patient in the TPVB group. No other complications were observed. CONCLUSIONS No difference was found regarding the clinical efficacy in the two groups. However, ultrasound-guided TPVB was superior to ultrasound-guided ICBN during VATS for pulmonary lobectomy under spontaneous-ventilating anesthesia. Additionally, vascular puncture should receive more attention.
RESUMO OBJETIVO O objetivo do presente estudo é comparar a eficácia de duas técnicas diferentes para o bloqueio nervoso torácico durante cirurgia torácica vídeo-assistida (CTVA) e anestesia com ventilação espontânea. METODOLOGIA Cem pacientes foram incluídos no estudo e divididos em dois grupos. Em um (grupo P), foi utilizada a abordagem de BPVT e no outro (grupo I), a abordagem de BIC. Então, a taxa de eficácia clínica, duração do procedimento de bloqueio e suas complicações foram registradas para a comparação do efeito das duas abordagens. RESULTADOS Nenhuma diferença foi observada no efeito clínico do bloqueio nervoso torácico entre os dois grupos. Dois pacientes no grupo de BIC foram convertidos para anestesia geral devido a fibrilação mediastinal grave (grau três). O número de pacientes com fibrilação mediastinal de grau um no grupo de BPVT foi significativamente maior do que no grupo de BIC. Perfuração vascular foi detectada em quatro pacientes do grupo de BIC e em um do grupo de BPVT. Não foram observadas outras complicações. CONCLUSÃO Não houve diferença de eficácia clínica entre os dois grupos. No entanto, BPVT guiado por ultrassom foi superior ao BIC guiado por ultrassom durante CTVA para lobectomia pulmonar com anestesia em ventilação espontânea. Além disso, deve-se prestar mais atenção quanto à perfuração vascular.

Abstract: Introduction: In recent years, there has been an increase in the number of medical residency programs in all regions of Brazil, only in the last 4 years, from 2014 to 2018, there was an increase from 18,953 general spots offered for the first year of medical residency to 26,094, 37% more, this was also observed in General Surgery Residencies around Brazil. As a result, the number of general surgeons has increased substantially, from 12,430 in 2008 to 34,065 in 2018, an absolute percentage increase of 174%. These new surgeons are bringing with them their theoretical and practical knowledge already updated, regarding new techniques and surgical modalities. In this context, in the last 2 decades, video-assisted surgery has become the choice for numerous procedures in Brazil and in the World, considering its benefits for patients, such as less postoperative hospital stay and less metabolic response to surgical trauma, for example. The current study correlates the data between the increase in the number of spots in medical residency programs, related to the graduation of new surgeons in Brazil, to the increase of videolaparoscopic surgeries in the public health system. Methodology: Review and online analysis of the national electronic public health registry database - DATASUS. The most performed Surgeries in Brazil were chosen for our data analysis. Results: The results were divided into five geographically distributed areas in Brazil. At the end of the current study, the number of video-assisted surgeries increased by 233%, accompanied by a 63% increase in the number of medical residency openings and a 174% absolute increase in the number of new surgeons in Brazil at the same period. Conclusion: The current study showed that the increase in the number of video-assisted surgeries in the country is related to the exponential increase in the number of medical residency spots and, consequently, to the number of new graduated general surgeons. This increase occurs more and more in a context of videolaparoscopic techniques, revealing multiple benefits already recognized for patients. We could conclude, therefore, that the increase in the number of medical residencies in general surgery - which are increasingly teaching videolaparoscopic techniques - has contributed as a complementary factor to the increase in the number of video-assisted surgeries observed in all regions of Brazil.
Resumo: Introdução: Nos últimos anos, houve um aumento no número de vagas de residência médica em todas as regiões do Brasil. Apenas nos últimos quatro anos, de 2014 a 2018, houve um aumento de 18.953 vagas gerais ofertadas para o primeiro ano de residência médica para 26.094, 37% a mais, o que foi acompanhado também pela área de cirurgia geral. Em consequência, o número de cirurgiões gerais vem aumentando substancialmente, de 12.430 em 2008 para 34.065 em 2018, um aumento percentual absoluto de 174%. Esses novos cirurgiões vêm trazendo consigo seus conhecimentos teóricos e práticos já atualizados, em sua maioria, de novas técnicas e modalidades cirúrgicas. Nesse contexto, nas últimas duas décadas a cirurgia videoassistida vem se tornando a via de escolha para inúmeros procedimentos no Brasil e no mundo, tendo em vista seus benefícios para os pacientes, tais como menor permanência hospitalar no pós-operatório e menos resposta metabólica ao trauma cirúrgico. Este estudo correlaciona o aumento do número de vagas em residência médica e consequentemente de novos cirurgiões ao aumento de cirurgias videolaparoscópicas no sistema público de saúde. Metodologia: Os dados para revisão foram extraídos do Departamento de Informática do Sistema Único de Saúde (Datasus). Escolheram-se as cirurgias com maior frequência para análise dos dados. Resultados: Os resultados foram divididos nas cinco áreas geograficamente distribuídas pelo Brasil. Ao final do estudo atual, demonstrou-se que o número de cirurgias videoassistidas aumentou em 233%, acompanhado pela elevação de 63% no número de vagas de residência médica e acréscimo de 174% no número de novos cirurgiões no Brasil, no mesmo período. Conclusão: O atual estudo demonstrou que o aumento do número de cirurgias videoassistidas no país está relacionado diretamente com o aumento exponencial do número de vagas de residência médica e, por consequência, do número de novos cirurgiões gerais. A formação desses novos cirurgiões gerais ocorre, cada vez mais, num contexto de técnicas videolaparoscópicas que trazem consigo inúmeros benefícios já reconhecidos para os pacientes. Conclui-se, portanto, que o acréscimo no número de vagas de residências médicas em cirurgia geral - que cada vez mais empregam os ensinamentos em técnicas videolaparoscópicas - tem contribuído como fator complementar para o aumento do número de cirurgias videoassistidas observado em todas as regiões do Brasil.
RESUMEN
ABSTRACT Introduction: the onset of minimally invasive surgery, such as laparoscopic surgery, was accompanied by an increased frequency of complications, many of which were life-threatening. With the objective of minimizing morbidity and mortality and accelerating the learning curve, video laparoscopic surgery simulators were developed to improve the psychomotor skills required for these procedures. Objective: to compare the performance of second year medical students of the Lutheran University of Brazil, in simulated videolaparoscopic surgeries performed at the Realistic Simulation Center of the Faculty of Health Sciences of Porto Alegre. Method: prospective cohort study with 16 medical students with no prior experience in video-surgery simulation. The students performed simulated exercises and were evaluated regarding Coordination, Navigation by Instrument and Time in the accomplishment of the procedures. Results: the sample consisted of 69% women and 31% men with a mean age of 23.2 years. The students obtained better results in the second simulation application. The skill in Navigation by Instrument task was the one that showed the best evolution in the studied group. The Total Time in the accomplishment of the procedures was the parameter with greater difference between the successive simulations. Conclusion: medical students presented a significant improvement in their performance with the repetition of the simulation exercises, demonstrating that the Laparoscopic Surgery Simulators are a promising tool in medical training and development of surgical skills.
RESUMO Introdução: o início da cirurgia minimamente invasiva, como a cirurgia laparoscópica, foi acompanhado por frequência aumentada de complicações, muitas com risco de morte. Com o objetivo de minimizar a morbidade e mortalidade e acelerar a curva de aprendizado, foram desenvolvidos simuladores de cirurgia videolaparoscópica para aprimoramento de habilidades psicomotoras necessárias nestes procedimentos. Objetivo: comparar o desempenho de acadêmicos do segundo ano de medicina da Universidade Luterana do Brasil, na realização de cirurgias videolaparoscópicas simuladas, feitas no Centro de Simulação Realística da Faculdade de Ciências da Saúde de Porto Alegre. Método: estudo prospectivo de coorte com 16 alunos de Medicina sem experiência prévia em simulação de vídeocirurgia. Os alunos realizaram exercícios simulados e foram avaliados quanto a Coordenação, Navegação por Instrumento e Tempo na Realização dos Procedimentos. Resultados: a amostra foi composta por 69% de mulheres e 31% de homens com média de idade de 23,2 anos. Os acadêmicos obtiveram melhora dos resultados na segunda aplicação da simulação. A habilidade na tarefa Navegação por Instrumento foi a que teve melhor evolução no grupo de alunos avaliados. O Tempo Total na realização dos procedimentos foi o parâmetro com maior diferença entre as simulações sucessivas. Conclusão: os acadêmicos de Medicina apresentaram expressiva melhora de desempenhos com a repetição dos exercícios de simulação, demonstrando que os Simuladores de Cirurgia Videolaparoscópica são ferramentas promissoras no treinamento de habilidades cirúrgicas na formação médica.

ABSTRACT Posterior fractures of the orbital floor are challenging, since an incomplete visualization of the defect through conventional surgical accesses may compromise the surgical outcome. The use of the endoscope as an auxiliary method during orbital reconstructions may be considered as a tool of considerable importance, mainly due to the visualization of the whole extension of fracture and adaptation of meshes or bone grafts. This study aims to report a clinical case of a patient diagnosed with extensive blowout fracture showing diplopy, enophthalmos, and ophthalmoplegia in supraversion, who underwent a subciliary approach combined with transantral video assisted surgery. There were no intercurrences on the procedure. Currently, patient has 1 year of follow up, with reestablished orbital function and architecture.
RESUMO As fraturas posteriores do assoalho orbital são desafiadoras, visto que a incompleta visualização do defeito por meio dos acessos cirúrgicos convencionais poderá comprometer o resultado cirúrgico. O uso do endoscópio como método auxiliar durante as reconstruções orbitais pode ser considerado uma ferramenta de grande importância principalmente para visualização de toda a extensão da fratura e adaptação das malhas ou enxertos ósseos. Este trabalho tem como objetivo relatar um caso clínico de um paciente diagnosticado com uma extensa fratura blowout apresentando clinicamente diplopia, enoftalmo e oftalmoplegia em supraversão, o qual foi submetido a tratamento através da abordagem subciliar combinada com a cirurgia vídeo-assistida transantral. O procedimento foi realizado sem intercorrências, estando o paciente com 1 ano de acompanhamento, com função e arquitetura orbital restabelecidos.

ABSTRACT Purpose: To investigate the effect of robot assisted laparoscopic radical prostatectomy (RALP) and open retropubic radical prostatectomy (RRP) on early renal function in this study. Materials and Methods: Preoperative and postoperative urea, creatinine, Hb, eGFR values of patients who had undergone RALP and RRP with prostate cancer (PCa) diagnosis were recorded in our clinic. The percentages of change in these values are calculated. Preoperative and postoperative urea, creatinine, Hb and eGFR changes were compared with each other. Student-t test was used for intergroup comparison, and paired sample t test was used to compare changes between preoperative and postoperative values of the same group. Results: There were 160 and 93 patients in the RALP and RRP group, respectively. In the RALP group, postoperative urea and creatinine increased significantly compared to preoperative baseline values while eGFR was decreased (p = 0.0001, p = 0.001, p = 0.0001, respectively). Except for Hb in the RRP group, the changes in these values were statistically insignificant (p = 0.50, p = 0.75, p = 0.30, respectively). Conclusions: We should be more careful when we perform RALP in patients at risk of impaired renal function despite being a minimally invasive surgical method with superior visual characteristics.

RESUMEN Paciente de 36 años en tratamiento de leucemia mieloide crónica con nilotinib a quien se le diagnostica hipertiroidismo por síntomas clínicos y exámenes de laboratorio. Se inicia tratamiento con metimazol más propanolol. Los estudios imagenológicos muestran un tejido ectópico tiroideo cervical infrahiodeo lateralizado a la izquierda y un nódulo en la base de la lengua. Presentó toxicidad hepática atribuida al tratamiento por lo que se decide extirpación quirúrgica de tiroides ectópica dual. Por la edad de la paciente y preocupación acerca del resultado estético, se realiza una tiroidectomía videoasistida por via axilar de la tiroides ectópica cervical y una resección transoral de la tiroides ectópica lingual. La patología confirma tejido tiroideo en ambas localizaciones sin signos de malignidad. La paciente se recuperó sin complicaciones y sin cicatriz cervical.
ABSTRACT A 36-year-old female patient with chronic myeloid leukemia being treated with nilotinib who was diagnosed with hyperthyroidism both on clinical and laboratory examination is presented. Imaging studies found left lateralized ectopic thyroid tissue of infrahyoid localization and a nodule at the base of the tongue. Hepatic toxicity was attributed to medical treatment, surgical removal of the dual thyroid ectopia was proposed. Due to the patients age and cosmetical concerns, a minimally invasive surgery was undertaken thru a video assisted transaxillary thyroidectomy for the cervical thyroid ectopia and a video assisted trans oral approach for the lingual thyroid ectopia. Post op pathology confirmed thyroid tissue at both locations and also excluded malignancy. The patient fully recovered without any complicaction and witout a residual cervical scar.
