SUMMARY OBJECTIVE: The aim of this study is to evaluate the early results of robotic surgery-assisted low anterior resection for rectal cancer and transvaginal specimen extraction, regarding the operative time, operative and early postoperative complications, hospital stay, and pathological reports in a series of 10 patients. METHODS: From November 2016 to October 2019, case series study on patients diagnosed with RC was included in this study. All robotic-assisted low anterior resection of the rectum, vaginal removal of the specimen, colorectal anastomosis, and loop ileostomies were performed using the Da Vinci XI system. RESULTS: The mean age of patient was 64.8 (58-72) years. Low anterior resection was performed to seven patients, and very low anterior resection was performed to three patients. Total mesorectal excision of the rectum, transvaginal specimen extraction, transanal anastomoses, and protective ileostomy were performed in all 10 patients. The mean operative time was 275±30.50 min, and estimated blood loss was 50±10.50 mL. No patient required conversion to conventional surgery. Negative circumferential resection, proximal, and distal margins were accomplished negative. Mean number of lymph nodes harvested was 20±5.5. According to the pathological reports, all were adenocarcinoma. T1 stage was 80.0%, and T2 stage was 20.0%. Lymph node metastasis accounted for 80.0%. CONCLUSIONS: To our literature search, this is the first study reporting the early outcomes of the novel robotic surgery-assisted low anterior resection for rectal cancer and transvaginal specimen extraction by using the Da Vinci Xi system. It can be performed safely and successfully in selected patients by providing an excellent cosmetic body image, which may be important for women.

Abstract Jejunal adenocarcinoma is a rare type of primary small bowelmalignancy. It is generally diagnosed at late stages and as a surgical finding, with abdominal pain or discomfort being the main associated symptom. Cases presenting with perforation are even rarer, especially without disseminated disease. The relationship between cancer and coronavirus disease 2019 (COVID-19) is still being studied, as well as the postsurgical evolution of COVID-19 patients and its possible causality of intestinal perforation. We present the case of a perforated jejunal adenocarcinoma in a COVID-19-positive patient, in whom the symptomatology secondary to the perforation led to an early diagnosis, treatment and adequate postsurgical evolution, despite the concomitant condition.

Resumo O adenocarcinoma jejunal é um tipo raro de malignidade primária do intestino delgado, o qual geralmente é diagnosticado em estágios tardios e como achado cirúrgico, sendo a dor ou o desconforto abdominal o principal sintoma associado. Casos que apresentam perfuração são ainda mais raros, principalmente sem doença disseminada. A relação entre câncer e a cornonavirus disease 2019 (covid-19) ainda está sendo estudada, assim como a evolução pós-cirúrgica de pacientes com covid-19 e sua possível causalidade de perfuração intestinal. Apresentamos o caso de um adenocarcinoma jejunal perfurado em um paciente positivo para covid-19, em que a sintomatologia secundária à perfuração levou a um diagnóstico precoce, tratamento e evolução pós-cirúrgica adequada, apesar da condição concomitante.

ABSTRACT BACKGROUND: As age advances, a higher burden of comorbidities and less functional reserve are expected, however, the impact of aging in the surgical outcomes of gastric cancer (GC) patients is unknown. OBJECTIVE: The aim of this study is to evaluate surgical outcomes of GC patients according to their age group. METHODS: Patients submitted to gastrectomy with curative intent due to gastric adenocarcinoma were divided in quartiles. Each group had 150 patients and age limits were: ≤54.8, 54.9-63.7, 63.8-72, >72. The outcomes assessed were: postoperative complications (POC), 90-day postoperative mortality, disease-free survival (DFS) and overall survival (OS). RESULTS: Major surgical complications were 2.7% in the younger quartile vs 12% for the others (P=0.007). Major clinical complications raised according to the age quartile: 0.7% vs 4.7% vs 5.3% vs 7.3% (P<0.042). ASA score and age were independent risk factors for major POC. The 90-day mortality progressively increased according to the age quartile: 1.3% vs 6.0% vs 7.3% vs 14% (P<0.001). DFS was equivalent among quartile groups, while OS was significantly worse for those >72-year-old. D2 lymphadenectomy only improved OS in the three younger quartiles. Age >72 was an independent risk factor for worse OS (hazard ratio of 1.72). CONCLUSION: Patients <55-year-old have less surgical complications. As age progresses, clinical complications and 90-day mortality gradually rise. OS is worse for those above age 72, and D2 lymphadenectomy should be individualized after this age.

RESUMO CONTEXTO: Conforme a idade avança, se esperam mais morbidades e menor reserva funcional. Entretanto não está claro qual o impacto do envelhecimento nos resultados cirúrgicos do câncer gástrico (CaG). OBJETIVO: O intuito deste estudo é avaliar os resultados cirúrgicos de pacientes com CaG de acordo com o grupo etário. MÉTODOS: Pacientes submetidos a gastrectomia por adenocarcinoma gástrico com intuito curativo foram divididos em quartis. Cada grupo incluiu 150 indivíduos e os limites etários foram: ≤54,8; 54,9-63,7; 63,8-72; >72. Os resultados avaliados foram: complicações pós-operatórias (CPO), mortalidade em 90 dias, sobrevida livre de doença (SLD) e sobrevida global (SG). RESULTADOS: Complicações cirúrgicas maiores ocorreram em 2,7% dos pacientes no quartil mais jovem vs 12% para os demais (P=0,007). A incidência de complicações clínicas maiores aumentou conforme o quartil: 0,7% vs 4,7% vs 5,3% vs 7,3% (P<0,042). A pontuação ASA e a idade foram fatores de risco independentes para CPO maiores. A mortalidade em 90 dias aumentou progressivamente conforme o quartil etário: 1,3% vs 6,0% vs 7,3% vs 14% (P<0,001). A SLD foi equivalente entre os quartis, enquanto a SG foi significativamente pior para os >72 anos de idade. Linfadenectomia D2 aumentou a SG apenas para os 3 quartis mais jovens. Idade > 72 foi fator independente de risco para pior SG (razão de chances de 1,72) CONCLUSÃO: Pacientes < 55 anos tem menos complicações cirúrgicas. Conforme a idade avança, as complicações clínicas e a mortalidade em 90 dias aumenta gradualmente. A SG é pior se >72 anos e a indicação de linfadenectomia D2 deve ser individualizada a partir dessa idade.

ABSTRACT Objectives: the surgical approach persists as the main treatment for esophageal cancer. This study compares the patients of the same institution over time at three different times. Methods: this is a retrospective, observational, descriptive study comparing the surgical outcomes obtained by the Division of Surgical Oncology of Erasto Gaertner Hospital. The sample was divided into Period 1 (1987-1997), Period 2 (1998-2003) and Period 3 (2007-2015). Survival rates and disease-free survival were estimated by the Kaplan-Maier method. Survival predictors were identified with Cox regression. ANOVA test was used for comparison between groups. Data were analyzed with SPSS 25.0 and STATA 16, and p<0.05 was considered statistically significant. Results: a total of 335 patients underwent esophagectomy or esophagogastrectomy. When the clinical characteristics of the 3 groups were compared, there was no statistically significant difference. Neoadjuvance was significantly higher in Period 3 (55.4% of patients). We found a histological change in the diagnosis over time, with a significant increase in adenocarcinoma. Morbidity and mortality rates were higher in Period 3. The main complications were pulmonary and anastomotic fistulas. Overall survival in 5 years increased over time, reaching 59.7% in Period 3. Conclusions: better neoadjuvant treatment contributed to increase the global survival of patients, despite greater rate of immediate complications to surgery.

RESUMO Objetivo: A abordagem cirúrgica persiste como tratamento principal para o câncer de esôfago. O presente estudo compara as casuísticas da mesma instituição ao longo do tempo, em três momentos diferentes. Métodos: Estudo descritivo retrospectivo comparativo observacional dos resultados cirúrgicos obtidos pelo Serviço de Cirurgia Oncológica do Hospital Erasto Gaertner. A amostra foi dividida em: Período 1 (1987-1997), Período 2 (1998-2003) e Período 3 (2007-2015). Taxas de sobrevida e sobrevida livre de doença foram estimadas pelo método de Kaplan-Maier. Preditores de sobrevida foram identificados com regressão de Cox. Para a comparação entre os grupos foi utilizado teste ANOVA. Os dados foram analisados com os programas SPSS 25.0 e STATA 16, sendo p<0,05 considerado estatisticamente significativo. Resultados: Ao todo, 335 doentes foram submetidos a esofagectomia ou esofagogastrectomia. Quando comparadas as características clínicas dos 3 grupos não houve diferença estatística significativa. A realização de neoadjuvância foi significativamente maior no Período 3 (55,4% dos pacientes). Verificamos uma mudança histológica do diagnóstico no decorrer do tempo, com um aumento significativo do adenocarcinoma. As taxas de morbimortalidade foram superiores no Período 3. As principais complicações foram pulmonares e de fistulas anastomóticas. A sobrevida global em 5 anos foi aumentando no decorrer do tempo, atingindo 59,7% no Período 3. Conclusões: Melhor tratamento neoadjuvante contribuiu para aumentar a sobrevida global dos pacientes, apesar de maior incidência de complicações imediatas à cirurgia.

RESUMO - RACIONAL: A cirurgia de resgate é definida como a ressecção cirúrgica após falha de primeiro tratamento com intuito curativo. OBJETIVO: Relatar a experiência de um centro de referência no tratamento do câncer gástrico com a cirurgia de resgate para o adenocarcinoma de estômago. MÉTODOS: Análise retrospectiva dos pacientes com câncer gástrico operados entre 2009 e 2020. RESULTADOS: 40 pacientes foram submetidos à tentativa de gastrectomia de resgate com intuito curativo. Para análise, foram divididos em dois grupos: 23 pacientes após ressecção endoscópica e 17 após gastrectomia. No primeiro grupo, todos tiveram ressecção com margens livres, a média de internação foi 15,7 dias e 2 (8,6%) tiveram complicações maiores. No seguimento médio de 37,2 meses, houve apenas 1 recidiva. A sobrevida global média foi 46 meses. No grupo pós-gastrectomia 9 (52,9%) foram resgatados com intenção curativa, a média de internação foi 12,2 dias e 3 (17,6%) apresentaram complicações maiores. No seguimento médio de 22 meses, 5 recidivaram. A sobrevida global média e a sobrevida livre de doença foram respectivamente: 24 e 16,5 meses. CONCLUSÃO: A cirurgia de resgate no câncer gástrico oferece nova possibilidade de controle da doença a longo prazo e/ou aumento de sobrevida, tendo taxa de complicações aceitáveis.

ABSTRACT - BACKGROUND: Salvage surgery (SS) is defined as surgical resection after the failure of the first treatment with curative intent. AIM: The aim of this study was to report the experience of a reference center with SS for stomach adenocarcinoma. METHODS: This is a retrospective study of patients with gastric cancer (GC) operated on between 2009 and 2020. RESULTS: Notably, 40 patients were recommended for salvage gastrectomy with curative-intent treatment. For analysis purpose, patients were divided into two groups: 23 patients after endoscopic resection and 17 patients after gastrectomy. In the first group, all patients underwent R0 resection, their average hospital length of stay (LOS) was 15.7 days, and 2 (8.6%) patients had major complications. During the average follow-up of 37.2 months, there was only one recurrence. The median overall survival (OS) was 46 months. In the postgastrectomy group, 9 (52.9%) patients were rescued with curative intent, the average hospital LOS was 12.2 days, and 3 (17.6%) had major complications. In a mean follow-up of 22 months, five patients relapsed. Median OS and disease-free survival were 24 and 16.5 months, respectively. CONCLUSION: SS in GC offers the possibility of long-term disease control and increased survival rate with an acceptable complication rate.

ABSTRACT Background: Gastric and esophagogastric junction adenocarcinoma are responsible for approximately 13.5% of cancer-related deaths. Given the fact that these tumors are not typically detected until they are already in the advanced stages, neoadjuvancy plays a fundamental role in improving long-term survival. Identification of those with complete pathological response (pCR) after neoadjuvant chemotherapy (NAC) is a major challenge, with effects on organ preservation, extent of resection, and additional surgery. There is little or no information in the literature about which endoscopic signs should be evaluated after NAC, or even when such re-evaluation should occur. Aim: To describe the endoscopic aspects of patients with gastric and esophagogastric junction adenocarcinomas who underwent NAC and achieved pCR, and to determine the accuracy of esophagogastroduodenoscopy (EGD) in predicting the pCR. Methods: A survey was conducted of the medical records of patients with these tumors who were submitted to gastrectomy after NAC, with anatomopathological result of pCR. Results: Twenty-nine patients were identified who achieved pCR after NAC within the study period. Endoscopic responses were used to classify patients into two groups: G1-endoscopic findings consistent with pCR and G2-endoscopic findings not consistent with pCR. Endoscopic evaluation in G1 was present in an equal percentage (47.4%; p=0.28) in Borrmann classification II and III. In this group, the predominance was in the gastric body (57.9%; p=0.14), intestinal subtype with 42.1% (p=0.75), undifferentiated degree, 62.5% (p=0.78), Herb+ in 73.3% (p=0.68). The most significant finding, however, was that the time interval between NAC and EGD was longer for G1 than G2 (24.4 vs. 10.2 days, p=0.008). Conclusion: EGD after NAC seems to be a useful tool for predicting pCR, and it may be possible to use it to create a reliable response classification. In addition, the time interval between NAC and EGD appears to significantly influence the predictive power of endoscopy for pCR.

RESUMO Racional: O adenocarcinoma gástrico e da junção esofagogástrica é responsável por aproximadamente 13,5% das mortes relacionadas ao câncer. Dado que esses tumores não são normalmente detectados até que já estejam em estágios avançados, a neoadjuvância desempenha um papel fundamental na melhoria da sobrevida em longo prazo. A identificação daqueles com resposta patológica completa (pCR) após a quimioterapia neoadjuvante (NAC) é um grande desafio, com efeitos na preservação do órgão, extensão da ressecção e cirurgia adicional. Há pouca ou nenhuma informação na literatura sobre quais sinais endoscópicos devem ser avaliados após a NAC, ou mesmo quando essa reavaliação deve ocorrer. Objetivo: Descrever os aspectos endoscópicos de pacientes com adenocarcinoma gástrico e da junção esofagogástrica que foram submetidos à quimioterapia neoadjuvante e alcançaram pCR, e determinar a acurácia da esofagogastroduodenoscopia (EGD) em predizer a pCR. Métodos: Foram revisados os prontuários de pacientes submetidos à gastrectomia subtotal e total após NAC, com resultado anatomopatológico de pCR. Resultados: Vinte e nove pacientes que alcançaram pCR após NAC foram identificados no período estudado. As respostas endoscópicas foram usadas para classificar os pacientes em dois grupos: G1- achados endoscópicos consistentes com pCR, G2 - achados endoscópicos não consistentes com pCR. A avaliação endoscópica no G1 esteve presente em igual percentual (47,4%; p=0,28) na classificação de Borrmann II e III. Nesse grupo, a predominância foi no corpo gástrico (57,9%; p=0,14), subtipo intestinal com 42,1% (p=0,75), grau indiferenciado, 62,5% (p=0,78), Herb+ em 73,3% (p=0,68). O achado mais significativo, no entanto, foi que o intervalo de tempo entre NAC e EGD foi maior para G1 do que G2 (24,4 vs. 10,2 dias, p=0,008). Conclusão: A EGD após NAC, nessa pesquisa, sugeriu ser método útil para prever pCR, mediante uma classificação de resposta confiável. Além disso, o intervalo de tempo entre NAC e EGD parece influenciar significativamente a sua capacidade preditiva de diagnosticar a pCR.

RESUMEN Introducción: El tumor de pulmón de células no pequeñas es un problema de salud pública, y la primera causa de muerte por cáncer a nivel mundial. Objetivo: Describir las características epidemiológicas, clínicas e histológicas en la población de enfermos aquejados de cáncer de pulmón de células no pequeñas, así como de las técnicas de resección pulmonar y de linfadenectomías utilizadas. Métodos: Se realizó un estudio descriptivo y transversal en el Servicio de Cirugía General del Hospital Provincial "Saturnino Lora" de Santiago de Cuba, desde enero de 2009 hasta enero de 2019. La muestra aleatoria fue de 55 pacientes diagnosticados de cáncer de pulmón de células no pequeñas a los que se les realizó resección pulmonar más linfadenectomía mediastinal. Se utilizaron como medidas de resumen para caracterizar las variables, el número absoluto, el porcentaje y la media, así como la prueba de significación Ji al cuadrado de independencia para identificar su posible asociación. Resultados: Predominó el sexo femenino y el grupo etario de 55 a 64 años. El adenocarcinoma fue el tipo histológico más frecuente. El lóbulo superior izquierdo resultó el más afectado. La lobectomía pulmonar con disección ganglionar por muestreo fue la técnica quirúrgica más utilizada. Predominaron los pacientes en estadios IB y IIA de la enfermedad. Conclusión: La linfadenectomía sistemática del mediastino, permite una certera estadificación, lo que determina una mejor evaluación del tratamiento y del pronóstico en estos enfermos(AU)

ABSTRACT Introduction: Non-small cell lung tumor is a public health problem, and the leading cause of cancer death worldwide. Objective: To describe the epidemiological, clinical and histological characteristics in the population of patients suffering from non-small cell lung cancer, as well as the techniques of lung resection and lymphadenectomies used. Methods: A descriptive and cross-sectional study was carried out in the General Surgery Service of the Provincial Hospital "Saturnino Lora" in Santiago de Cuba, from January 2009 to January 2019. The random sample consisted of 55 patients diagnosed with cell lung cancer non-small patients who underwent lung resection plus mediastinal lymphadenectomy. The absolute number, the percentage and the mean were used as summary measures to characterize the variables, as well as the Chi-squared significance test of independence to identify their possible association. Results: The female sex and the age group 55 to 64 years predominated. Adenocarcinoma was the most frequent histological type. The left upper lobe was the most affected. Pulmonary lobectomy with sampling lymph node dissection was the most widely used surgical technique. Patients in stages IB and IIA of the disease predominated. Conclusion: Systematic lymphadenectomy of the mediastinum allows an accurate staging, which determines a better evaluation of treatment and prognosis in these patients(AU)

Abstract Objective To observe if the histopathological result of a conization performed after cervical adenocarcinoma in situ diagnosis is compatible with the histopathological analysis of a subsequent hysterectomy. Methods The present descriptive and observational research consisted of the analysis of the medical records of 42 patients who were diagnosed with in situ adenocarcinoma postconization. The analysis consisted of whether there was compatibility between the histopathological reports of conization and hysterectomy and if there was an association between adenocarcinoma in situ and another neoplasia (squamous disease). Interpretation of any immunohistochemistry reports obtained was also performed. In addition, clinical and epidemiological data were also analyzed. Results A total of 42 conizations were performed, 33 (79%) were cold knife conizations and 9 (21%) were loop electrosurgical excision procedures (LEEPs). Of the patients analyzed, 5 (10%) chose not to undergo subsequent hysterectomy to preserve fertility or were < 25 years old. Out of the 37 patients with adenocarcinoma in situ who underwent subsequent hysterectomy, 6 (16%) presented with residual disease. This findingprovedincompatiblewiththe finding of the conizations, which had ruled out invasive cancer. Conclusion The prevalence of adenocarcinoma in situ increased in the past years. There is still a large part of the medical literature that advocates the use of conservative treatment for this disease, even though it is common knowledge that it is a multifocal disease. However, the majority of studies advocate that hysterectomy should remain the preferred treatment for women who have already completed their reproductive purpose.

Resumo Objetivo Observar se o resultado proveniente de uma conização realizada após o diagnóstico de adenocarcinoma cervical in situ é compatível com a análise histopatológica da histerectomia. Métodos A pesquisa foi descritiva e observacional e consistiu na análise de prontuário de 42 pacientes que tiveram o diagnóstico de adenocarcinoma in situ obtidas por conização. Foram analisados se havia compatibilidade entre os laudos de conização e histerectomia, margens do cone, se havia associação com outra patologia (doença escamosa) e interpretação de eventuais laudos histoquímicos obtidos. Além disso, também foram analisados dados clínico-epidemiológicos. Resultados Foram realizadas 42 conizações, sendo 33 (79%) por cone clássico e 9 (21%) por cirurgia de alta frequência. Das pacientes analisadas, 5 (10%) não foram submetidas a histerectomia por desejarem manter a fertilidade ou por terem idade < 25 anos. Das 37 pacientes com adenocarcinoma in situ no exame prévio realizado e que foram submetidas à histerectomia posteriormente, 6 (16%) apresentaram doença residual após o procedimento cirúrgico, apresentando laudos do anatomopatológico pós-histerectomia incompatíveis com o achado na conização que atestava margens livres. Conclusão A prevalência do adenocarcinoma in situ vemaumentando cada vez mais. Ainda há uma grande parte da literatura que defende o uso do tratamento conservador para esta doença, mesmo sabendo que ela é uma doença multifocal e que pode estar presente mesmo em situações nas quais o anatomopatológico evidencie margens livres. Tendo em vista essas características, a maioria preconiza que a histerectomia continua a ser o tratamento preferencial nas mulheres que já completaram o seu intuito reprodutivo.

Introducción: El budding tumor (BT) es la presencia de células tumorales aisladas o en pequeños grupos situadas en el frente de invasión del tumor. Su hallazgo en alto grado es un factor de mal pronóstico independiente del cáncer colorrectal. El objetivo de este trabajo es determinar si el grado de BT está asociado con otros factores pronósticos del cáncer rectal. Material y métodos: Se incluyen las resecciones oncológicas de recto en el período 2013-2017. Los casos se agruparon según la densidad en la formación de los BT en 3 grupos, los de grado bajo, intermedio y alto. Se utilizó como valor estadístico el cálculo del odds ratio (OR). Resultados: Se analizaron las piezas de resección de 27 pacientes (15 mujeres y 12 hombres) con una media de edad de 68,4 años (40-86). Se calculó el OR para invasión ganglionar, vascular y recidiva en función del grado de budding tumoral. Discusión: Se observó una tendencia a la presencia de factores histológicos de mal pronóstico en relación al budding de alto grado, si bien el bajo número de casos no permitió demostrarlo en este estudio. Conclusiones: El análisis del grado de tumor budding es reproducible y podría ayudar a identificar pacientes con cáncer rectal de peor pronóstico. (AU)

Introduction: Tumor budding (BT) is defined as isolated or small groups of neoplastic cells located at the invasive front of the tumor. High-grade BT is a poor prognostic factor in colorectal cancer. Objective: To determine if the degree of BT is associated with other prognostic factors in rectal cancer. Materials and methods: Rectal oncological resections during the 2013-2017 period were included. Cases were stratified according to the density in the formation of BT in 3 groups: low, intermediate and high. The calculation of the odds ratio (OR) was used as a statistical value. Results: The resection specimens of 27 patients (15 women and 12 men) with a mean age of 68.4 years (40-86) were analyzed. OR for node metastases, vascular invasion and relapse was calculated according to tumor budding grade. Discussion: High-grade tumor budding seems to associate with the presence of poor prognostic factors. However, it was not possible to demonstrate it because of the small sample size. Conclusions: Tumor budding is a reproducible marker and could help to identify rectal cancer patients with a worse prognosis. (AU)

Primary enteric adenocarcinoma is a rare variant of primary pulmonary adenocarcinoma. This disease lacks a distinctive manifestation and often requires pathological examination to make a definite diagnosis. A male patient visited the Second Xiangya Hospital, Central South University for consistent cough and sputum production for about 1 year. Anti-infection therapy was given but it showed ineffectiveness. Enteric adenocarcinoma was diagnosed after percutaneous lung biopsy according to pathological findings. Combining this case with relevant literature, we summarized the characteristics to raise physicians' awareness for this rare subtype.

ABSTRACT Background: The octogenarian population is expanding worldwide and demand for gastrectomy due to gastric cancer in this population is expected to grow. However, the outcomes of surgery with curative intent in this age group are poorly reported and it is unclear what matters most to survival: age, clinical status, disease´s stage, or the extent of the surgery performed. Aim: Evaluate the results of gastrectomy in octogenarians with gastric cancer and to verify the factors related to survival. Methods: From prospective database, patients aged 80 years or older with histologically confirmed adenocarcinoma who had undergone gastrectomy with curative intent were selected. Factors related to postoperative complications and survival were studied. Results: Fifty-one patients fulfilled the inclusion criteria. A total of 70.5% received subtotal gastrectomy and in 72.5% D1 lymphadenectomy was performed. Twenty-five (49%) had complications, in eleven major complications occurred (seven of these were clinical complications). Hospital length of stay was longer (8.5 vs. 17.8 days, p=0.002), and overall survival shorter (median of 1.4 vs. 20.5 months, p=0.009) for those with complications. D2 lymphadenectomy and the presence of postoperative complications were independent factors for worse overall survival. Conclusion: Octogenarians undergoing gastrectomy with curative intent have high risk for postoperative clinical complications. D1 lymphadenectomy should be the standard of care in these patients.

RESUMO Racional: A população octogenária está expandindo mundialmente e é esperado que a demanda por gastrectomia devido a câncer gástrico nessa faixa também aumente. Entretanto, os resultados da operação curativa nessa população são pobremente reportados e não está claro o que mais importa no resultado: idade, status clínico, estágio da doença, ou a extensão da operação. Objetivos: Avaliar os resultados cirúrgicos da gastrectomia em octogenários e verificar os fatores relacionados com a sobrevida. Métodos: Através de revisão de banco de dados prospectivo, pacientes com 80 anos ou mais de idade e adenocarcinoma gástrico comprovado histologicamente e submetidos a gastrectomia com intuito curativo foram analisados. Fatores relacionados a complicações pós-operatórias e sobrevida foram estudadas. Resultados: Cinquenta e um pacientes preencheram os critérios de inclusão. A gastrectomia subtotal foi realizada em 70,5% dos casos e a linfadenectomia D1 em 72,5% dos pacientes. Complicações ocorreram em 25 pacientes (49%), sendo que em 11 elas foram graves (sete foram complicações clínicas). Pacientes com complicações tiveram maior duração da internação hospitalar (8,5 vs. 17,8 dias, p=0,002) e sobrevida global mais curta (mediana de 1,4 vs. 20,5 meses, p=0,009). Linfadenectomia D2 e a presença de complicações foram fatores independentes de pior sobrevida global. Conclusão: Os octogenários submetidos à gastrectomia com intenção curativa apresentam alto risco de complicações clínicas no pós-operatório. A linfadenectomia D1 deve ser o padrão de atendimento nesses pacientes.

ABSTRACT Aims: Radical prostatectomy (RP) can result in urinary incontinence (UI) and erectile dysfunction (ED), which negatively impact quality of life (QoL). This study aimed to evaluate the effects of a perioperative pelvic floor muscle training (PFMT) program versus usual care on early recovery of urinary continence and erectile function after RP. Materials and Methods: Of 59 eligible men, 31 were randomly allocated into 2 groups: Group 1 (Control, N=15) received usual post-RP care; and Group 2 (Physical therapy, N=16) received two pre-RP physical therapist-guided PFMT sessions, including exercises and electromyographic biofeedback, and verbal and written instructions to continue PFMT until RP, which was then resumed after urethral catheter removal. The International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire were used to evaluate UI and ED, respectively. Results: Demographic characteristics were similar in both groups. Three months after RP, the UI rate was 72.7% and 70.0% in Groups 1 and 2, respectively (P >0.05). The severity and frequency of UI and its impact on QoL were evaluated by the ICIQ-Short Form, with scores of 6.9±6.26 in Group 1 and 7.0±5.12 in Group 2 (P >0.05). The IIEF-5 scores were similar in Groups 1 and 2 (5.73±7.43 vs. 6.70±6.68, respectively) (P >0.05). Conclusion: Our pre-RP protocol of two physical therapist-assisted sessions of PFMT plus instructions did not significantly improve urinary continence or erectile function at 3 months after RP.

Resumen: El síndrome de Maffucci se caracteriza por la presencia de múltiples encondromas y hemangiomas que pueden afectar tejidos blandos y otros órganos. El riesgo de transformación maligna de las lesiones es de 100% durante la vida del individuo, siendo el condrosarcoma el tumor maligno más frecuentemente asociado. Se presenta el caso de un hombre de 44 años de edad con diagnóstico de síndrome de Maffucci, el cual desarrolló un doble primario sincrónico: condrosarcoma y sarcoma fusocelular de alto grado multicéntrico de región escapular y tricipital, fue tratado con desarticulación interescapulotorácica, mostró progresión acelerada y enfermedad pulmonar. Existen otras neoplasias asociadas al síndrome de Maffucci tales como adenocarcinoma de páncreas, tumores mesenquimales de ovario, gliomas, astrocitomas y tumores de la pituitaria. Por lo que resulta muy interesante reportar la asociación infrecuente entre un sarcoma fusocelular y un condrosarcoma secundario en pacientes con síndrome de Maffucci. El seguimiento en este grupo de pacientes es complejo y se basa en la búsqueda intencionada de lesiones con crecimiento acelerado, prestando atención en lesiones de crecimiento progresivo, síntomas clínicos o datos radiológicos de malignidad.

Abstract: Maffucci syndrome is characterized by the presence of multiple enchondromes and hemangiomas that can affect soft tissues and other organs. The risk of malignant transformation of lesions is 100% during the life of the individual, with chondrosarcoma being the most frequently associated malignant tumor. We present the case of a 44-year-old man diagnosed with Maffucci syndrome who developed a synchronous double primary: chondrosarcoma and high-grade multicenter fusocellular sarcoma of scapular and tricipital region, was treated with disarticulation interscapule-thoracic, presented accelerated progression and lung disease. There are other neoplasms associated with Maffucci syndrome, such as pancreatic adenocarcinoma, mesenchymal ovarian tumors, gliomas, astrocytomas and pituitary tumors. It is therefore very interesting to report the uncommon association between fusocellular sarcoma and secondary chondrosarcoma in patients with Maffucci syndrome. Follow-up in this group of patients is complex and is based on the intentional search for accelerated growing lesions, paying attention to progressive growth injuries, clinical symptoms or radiological malignancy data.

ABSTRACT BACKGROUND: Pancreaticoduodenectomy (PD) with the resection of venous structures adjacent to the pancreatic head, even in cases of extensive invasion, has been practiced in recent years, but its perioperative morbidity and mortality are not completely determined. OBJECTIVE: To describe the perioperative outcomes of PD with venous resections performed at a tertiary university hospital. METHODS: A retrospective study was conducted, classified as a historical cohort, enrolling 39 individuals which underwent PD with venous resection from 2000 through 2016. Preoperative demographic, clinical and anthropometric variables were assessed and the main outcomes studied were 30-day morbidity and mortality. RESULTS: The median age was 62.5 years (IQ 54-68); 55% were male. The main etiology identified was ductal adenocarcinoma of the pancreas (82.1%). In 51.3% of cases, the portal vein was resected; in 35.9%, the superior mesenteric vein was resected and in the other 12.8%, the splenomesenteric junction. Regarding the complications, 48.7% of the patients presented some type of morbidity in 30 days. None of the variables analyzed was associated with higher morbidity. Perioperative mortality was 15.4% (six patients). The group of individuals who died within 30 days presented significantly higher values for both ASA (P=0.003) and ECOG (P=0.001) scores. CONCLUSION: PD with venous resection for advanced pancreatic neoplasms is a feasible procedure, but associated with high rates of morbidity and mortality; higher ASA e ECOG scores were significantly associated with a higher 30-day mortality.

RESUMO CONTEXTO: A duodenopancreatectomia (DP) com ressecção de estruturas venosas adjacentes à cabeça do pâncreas, mesmo em casos de invasão extensa, tem sido praticada nos últimos anos, mas sua morbidade e mortalidade perioperatórias não são completamente determinadas. OBJETIVO: Descrever os resultados perioperatórios de DP com ressecções venosas realizadas em um hospital terciário universitário. MÉTODOS: Foi realizado estudo retrospectivo, classificado como coorte histórica, envolvendo 39 indivíduos submetidos à DP com ressecção venosa entre 2000 e 2016. Foram estudadas variáveis demográficas, clínicas e antropométricas pré-operatórias e os desfechos principais foram a morbidade e mortalidade em 30 dias. RESULTADOS: A mediana de idade foi 62,5 anos (IQ 54-68), sendo 55% dos indivíduos do sexo masculino. A principal etiologia identificada foi o adenocarcinoma ductal de pâncreas (82,1%). Em 51,3% dos casos, a veia porta foi submetida à ressecção; em 35,9%, a veia mesentérica superior foi ressecada e nos outros 12,8%, a junção esplenomesentérica. Em relação às complicações, 48,7% dos pacientes apresentaram algum tipo de morbidade em 30 dias. Nenhuma das variáveis analisadas associou-se à maior morbidade. A mortalidade perioperatória foi 15,4% (seis pacientes). O grupo de indivíduos que cursou com mortalidade em 30 dias apresentou escores significativamente mais altos de ASA (P=0,003) e ECOG (P=0,001). CONCLUSÃO: A DP com ressecção venosa para neoplasias avançadas do pâncreas é um procedimento factível, porém que se acompanha de altos índices de morbidade e mortalidade; escores de ASA e ECOG altos são fatores significativamente associados à maior mortalidade.

INTRODUCCIÓN: El adenocarcinoma de cuerpo y cola de páncreas corresponde a cerca de un tercio del total de cánceres pancreáticos. Evoluciona en forma silenciosa hasta alcanzar estadios avanzados, llegando a comprometer muchas veces grandes vasos como tronco celíaco y sus ramas, y la arteria mesentérica superior. La resolución quirúrgica parece ser la única alternativa en estos casos. OBJETIVO: Presentar dos casos de adenocarcinoma de cuerpo y cola de páncreas tratados en nuestro hospital con pancreatectomía corpo-caudal y resección en bloque de tronco celíaco (procedimiento de Appleby modificado). DISCUSIÓN: Este procedimiento ha demostrado aumentar la sobrevida de estos pacientes, además de generar un alivio inmediato y duradero del dolor. Sin embargo, corresponde a una intervención con una alta morbilidad, siendo la fístula pancreática y la gastropatía isquémica las complicaciones más frecuentes. La evaluación del flujo de los vasos colaterales es un paso crítico para evitar las complicaciones isquémicas. CONCLUSIONES: La pancreatectomía corpo-caudal con resección en bloque de tronco celíaco, es una alternativa factible en adenocarcinoma de cuerpo y cola de páncreas localmente avanzado. Su indicación debe ser cuidadosa debido a que corresponde a un procedimiento con alta morbilidad.

INTRODUCTION: Adenocarcinoma of the body and tail of the pancreas corresponds to about one third of all pancreatic cancers. It evolves silently to reach advanced stages, often involving large vessels such as the celiac trunk and its branches, and the superior mesenteric artery. Surgical resolution seems to be the only alternative in these cases. AIM: To present two cases of adenocarcinoma of the body and tail of the pancreas treated in our hospital with distal pancreatectomy and celiac trunk en block resection (modified Appleby procedure). DISCUSSION: This procedure has been shown to increase the survival of these patients, in addition to generating immediate and lasting pain relief. However, it corresponds to an intervention with a high morbidity, being the pancreatic fistula and the ischemic gastropathy the most frequent complications. The evaluation of the flow of the collateral vessels is a critical step to avoid ischemic complications. CONCLUSIONS: Distal pancreatectomy with en bloc resection of the celiac trunk is a feasible alternative in locally advanced adenocarcinoma of the body and tail of the pancreas. Its indication must be careful since is a procedure with high morbidity.

ABSTRACT Introduction Robot-assisted radical prostatectomy (RARP) is the most recent surgical technique for localized prostate cancer. The Da Vinci (Intuitive Surgical, Sunnyvale, CA) system was first introduced in Brazil in 2008, with a fast growing number of surgeries performed each year. Objective Our primary endpoint is to analyze possible predictors of functional outcomes, related to patient and tumor features. As secondary endpoint, describe functional outcomes (urinary continence and sexual potency) from RARP performed in the Sírio-Libanês Hospital (SLH), a private institution, in São Paulo, from April 2008 to December 2015. Materials and Method Data from 104 consecutive patients operated by two surgeons from the SLH (MA and SA) between 2008 and 2015, with a minimum 12 months follow-up, were collected. Patient features (age, body mass index - BMI, PSA, date of surgery and sexual function), tumor features (tumor stage, Gleason and surgical margins) and follow-up data (time to reach urinary continence and sexual potency) were the variables collected at 1, 3, 6 and 12 month and every 6 months thereafter. Continence was defined as the use of no pad on medical interview and sexual potency defined as the capability for vaginal penetration with or without fosphodiesterase type 5 inhibitors. Results Mean age was 60 years old and mean BMI was 28.45 kg/m2. BMI >30kg/m2 (p<0.001) and age (p=0.011) were significant predictors for worse sexual potency after surgery. After 1, 3, 6 and 12 months, 20.7%, 45.7%, 60.9% and 71.8% from patients were potent, respectively. The urinary continence was reached in 36.5%, 80.3%, 88.6% and 92.8% after 1, 3, 6 and 12 months, respectively. Until the end of the study, only one patient was incontinent and 20.7% were impotent. Conclusion Age was a predictor of urinary and erectile function recovery in 12 months. BMI was significant factor for potency recovery. We obtained in a private hospital good functional results after 12 months of follow-up.

El adenocarcinoma de células basales, también conocido como carcinoma salival basaloide, adenoma maligno de células basales, es una neoplasia epitelial de bajo grado, infiltrante, localmente destructivo y con tendencia a ser recidivante. Su aparición es entre la 5ª y 6ª década de vida, sin predilección por sexo. Clínicamente se manifiesta con un edema o un aumento repentino de tamaño en la zona, de consistencia firme, crecimiento lento e indoloro. El diagnóstico de certeza es a través de la histopatología; su tratamiento quirúrgico, y tiene buen pronóstico en sus estadios iniciales (AU)

Basal cells adenocarcinoma also known as salivary basaloide carcinoma basal cells malignant adenoma is a low degree, infiltrating, locally destructive and prone to be relapsing, epithelial neoplasia. It occurs between the 5th and 6th decade of life, with no predilection for sex. Clinically it manifests with an edema or sudden increased size in the area, of firm consistency, slow growth and pain-less. Its treatment is surgical and the diagnosis of certainty is histopathological with a good prognosis. The purpose of this presentation is to show the case of a 57- years-old male patient with clinical and anatomopathological diagnosis of adenocarcinoma of basal cells located in the yugal mucosa (AU)

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.

Los linfomas derivados del tejido linfoide asociado a las mucosas (MALT) son entidades poco frecuentes, de bajo grado de malignidad con escaso o nulo compromiso ganglionar y representan cerca del 80% de los linfomas primarios pulmonares. La aparición sincrónica con adenocarcinoma de pulmón es un hallazgo extremadamente infrecuente. Presentamos el caso de un hombre de 68 años, ex-tabaquista, en quien durante el seguimiento de un nódulo pulmonar se identificó un segundo nódulo y la biopsia quirúrgica confirmó el diagnóstico de ambas neoplasias.

The lymphomas of mucosa-associated lymphoid tissue (MALT), are uncommon entities, of low grade of malignancy with very infrequent or no lymph node involvement. They represent about 80% of the primary pulmonary lymphomas. The synchronous appearance with lung adenocarcinoma is an extremely rare finding. We present the case of an ex-smoker 68-year-old man, in whom, in the follow-up of a pulmonary nodule, a second pulmonary nodule was found. The surgical biopsy confirmed the diagnosis of both neoplasms.
