ABSTRACT

ABSTRACT Despite the neuroanatomy knowledge of the prostate described initially in the 1980's and the robotic surgery advantages in terms of operative view magnification, potency outcomes following robotic-assisted radical prostatectomy still challenge surgeons and patients due to its multifactorial etiology. Recent studies performed in our center have described that, in addition to the surgical technique, some important factors are associated with erectile dysfunction (ED) following robotic-assisted radical prostatectomy (RARP). These include preoperative Sexual Health Inventory for Men (SHIM) score, age, preoperative Gleason score, and Charlson Comorbidity Index (CCI). After performing 15,000 cases, in this article we described our current Robotic-assisted Radical Prostatectomy technique with details and considerations regarding the optimal approach to neurovascular bundle preservation.

ABSTRACT

ABSTRACT Objective: to describe the use of the robotic platform in inguinal hernia recurrence after a previous laparoscopic repair. Methods: patients with recurrent inguinal hernias following a laparoscopic repair who have undergone robotic transabdominal preperitoneal between December 2015 through September 2020 were identified in a prospectively maintained database. Outcomes of interest included demographics, hernia characteristics, operative details and rates of 30-day surgical site occurrence, surgical site occurrences requiring procedural interventions, surgical site infection and hernia recurrence were abstracted. Results: nineteen patients (95% male, mean age 55 years, mean body mass index 28) had 27 hernias repaired (N=8 bilateral). Average operative time was 168.9 ± 49.3min (range 90-240). There were two intraoperative complications all of them were bleeding from the inferior epigastric vessel injuries. Three SSOs occurred (N=2 seromas and N=1 hematoma. After a median 35.7 months follow-up (IQR 13-49), no recurrence has been diagnosed. One patient developed chronic postoperative inguinal pain. Conclusions: on a small number of selected patients and experienced hands, we found that the use of the robotic platform for repair of recurrent hernias after prior laparoscopic repair appears to be feasible, safe and effective despite being technically demanding. Further studies in larger cohorts are necessary to determine if this technique provides any benefits in recurrent inguinal hernia scenario.


RESUMO Objetivo: descrevemos nossa experiência com uso da plataforma robótica no tratamento das recidivas operadas previamente por laparoscopia, mantendo assim uma proposta minimamente invasiva a esses pacientes, apesar de haver uma predileção pela via anterior e aberta nestes casos. Métodos: foram incluídos pacientes submetidos a hernioplastia inguinal robótica transabdominal pré-peritoneal como tratamento de recidiva e que foram operados previamente por laparoscopia, entre dezembro de 2015 e setembro de 2020 e mantidos em uma base de dados ambulatorial prospectiva. Variáveis de interesse incluíram dados demográficos, características herniárias, detalhes operatórios, ocorrências do sítio cirúrgico em 30 dias (com ou sem necessidade de intervenção), infeção do sítio cirúrgico, tempo de seguimento e taxa de recidiva. Resultados: dezenove pacientes (95% masculino, média de idade de 55 anos, média de índice de massa corporal 28kg/m2) e 27 hérnias operadas (N=8 bilaterais). Média de tempo cirúrgico 168.9±49.3 min (variando 90-240). N=2 complicações intraoperatórias por lesão de vasos epigástricos inferiores. N=2 seromas e N=1 hematoma foram identificados no pós-operatório; N=1 paciente apresentou dor crônica pós operatória. Após um tempo de seguimento médio de 35.7 meses (intervalo entre quartis 13-49), nenhuma recidiva foi diagnosticada. Conclusões: o uso da plataforma robótica parece ser seguro e efetivo no tratamento das recidivas operadas previamente laparoscopia, nesse pequeno grupo de pacientes selecionados, apesar de requerer expertise em cirurgia robótica. Outros estudos com maiores casuísticas são necessários para estabelecer o papel desta técnica no cenário das hérnias inguinais recidivadas.

ABSTRACT

ABSTRACT Objectives: minimally invasive inguinal hernia repair has proven advantages over open procedures including less pain and earlier return to normal activity. Robotic surgery adds ergonomics, a three-dimensional high definition camera and articulating instruments overcoming some laparoscopic limitations. We aimed to report the outcomes of the early experience of over 97 robotic inguinal hernia repairs performed by a referred surgical group in Brazil. Methods: a review of a prospective mantined database was conducted in patients submitted to robotic transabdominal preperitoneal (TAPP) inguinal hernia repairs between March 2016 and February 2020. Descriptive statistics were performed. Surgical outcomes data and patient follow-ups are reported. Results: retrospective chart review identified 97 patients submitted to robotic TAPP inguinal hernia repair. Mean age was 36.4 years, with median BMI of 26.9 kg/m2. Mean console time was 58 min (range 40-150) and patients were discharged within 24 hours of their stay in a majority of cases. Mesh was placed in all procedures and there were no conversion rates. Complications were low grade and no recurrence was seen after a mean follow-up of 642 days. Conclusion: this study represents to-date the first brazilian case series of robotic TAPP inguinal hernia repair. Our results encourage that robotic assisted TAPP inguinal hernia repair appears to be technically feasible and safe in experienced hands, with good outcomes achieving high health-related quality of life and low recurrence rates in the short and long term.


RESUMO Objetivo: a cirurgia minimamente invasiva das hérnias inguinais apresenta vantagens comprovadas em relação aos procedimentos convencionais, incluindo menos dor e retorno precoce às atividades rotineiras. A cirurgia robótica acrescenta uma melhor ergonomia, ótica estável tridimensional de alta definição e instrumentos articulados, superando algumas limitações laparoscópicas. O objetivo deste estudo é relatar os resultados da experiência inicial de 97 cirurgias de correção de hérnias inguinais robóticas pela técnica transabdominal pré-peritoneal (TAPP) realizadas por um grupo cirúrgico referência no Brasil. Métodos: foi realizada uma revisão de um banco de dados mantido prospectivamente de pacientes submetidos a cirurgias de hérnia inguinal TAPP robótica entre março de 2016 e fevereiro de 2020. Uma análise detalhada dos resultados foi feita e dados dos resultados cirúrgicos e acompanhamento dos pacientes são relatados. Resultados: a revisão retrospectiva do prontuário identificou 97 pacientes submetidos à cirurgia de hérnia inguinal TAPP robótica. A idade média foi de 36,4 anos, com IMC médio de 26,9 kg/m2. O tempo médio de procedimento cirúrgico no console robótico foi de 58 minutos. A colocação de prótese foi realizada em todos os procedimentos e não houve taxas de conversão ou intercorrências. Conclusão: este estudo representa a primeira série de casos de cirurgia robótica de hérnia inguinal pela técnica transabdominal pré-peritoneal no Brasil. Os resultados descritos reforçam que a hernioplastia inguinal robótica apresenta-se como tecnicamente viável e segura em mãos experientes, com bons resultados quanto a qualidade de vida e baixas taxas de recidiva a curto e longo prazo.

ABSTRACT

Abstract Background: The present study investigated the association between Postoperative Cognitive Dysfunction (POCD) and increased serum S100B level after Robotic-Assisted Laparoscopic Radical Prostatectomy (RALRP). Methods: The study included 82 consecutive patients who underwent RALRP. Serum S100B levels were determined preoperatively, after anesthesia induction, and at 30 minutes and 24 hours postoperatively. Cognitive function was assessed using neuropsychological testing preoperatively, and at 7 days and 3 months postoperatively. Results: Twenty four patients (29%) exhibited POCD 7 days after surgery, and 9 (11%) at 3 months after surgery. Serum S100B levels were significantly increased at postoperative 30 minutes and 24 hours in patients displaying POCD at postoperative 7 days (p = 0.0001 for both) and 3 months (p = 0.001 for both) compared to patients without POCD. Duration of anesthesia was also significantly longer in patients with POCD at 7 days and 3 months after surgery compared with patients without POCD (p = 0.012, p = 0.001, respectively), as was duration of Trendelenburg (p = 0.025, p = 0.002, respectively). Composite Z score in tests performed on day 7 were significantly correlated with duration of Trendelenburg and duration of anesthesia (p = 0.0001 for both). Conclusions: S100B increases after RALRP and this increase is associated with POCD development. Duration of Trendelenburg position and anesthesia contribute to the development of POCD. Trial Registry Number: Clinicaltrials.gov (N° NCT03018522).


Resumo Introdução: O presente estudo investigou a associação entre Disfunção Cognitiva Pós-Operatória (DCPO) e aumento do nível sérico de S100B após Prostatectomia Radical Laparoscópica Assistida por Robô (PRLAR). Métodos: O estudo incluiu 82 pacientes consecutivos submetidos à PRLAR. Os níveis séricos de S100B foram determinados: no pré-operatório, após indução anestésica, e aos 30 minutos e 24 horas do pós-operatório. A função cognitiva foi avaliada com testes neuropsicológicos no pré-operatório, no 7° dia pós-operatório (7 DPO) e aos 3 meses após a cirurgia (3 MPO). Resultados: Observamos 24 pacientes (29%) com DCPO no 7 DPO e 9 pacientes com DCPO (11%) após 3 meses da cirurgia. Quando comparados com os pacientes sem DCPO, os níveis séricos de S100B estavam significantemente aumentados aos 30 minutos e às 24 horas do pós-operatório nos pacientes que apresentaram DCPO no 7 DPO (p= 0,0001 para os dois momentos) e 3 meses após a cirurgia (p= 0,001 para os dois momentos) A duração anestésica também foi significantemente maior em pacientes com DCPO no 7 DPO e 3 MPO em comparação com pacientes sem DCPO (p= 0,012, p= 0,001, respectivamente), assim como a duração da posição de Trendelenburg (p= 0,025, p= 0,002, respectivamente). O escore Z composto nos testes realizados no 7 DPO foi significantemente correlacionado com a duração da posição de Trendelenburg e a duração da anestesia (p= 0,0001 para ambos). Conclusão: S100B aumenta após PRLAR e o aumento está associado ao desenvolvimento de DCPO. A duração anestésica e o tempo decorrido em posição de Trendelenburg contribuem para o desenvolvimento de DCPO. Número de registro do estudo: Clinicaltrials.gov (n° NCT03018522)

ABSTRACT

ABSTRACT Introduction: Robotic transanal surgery (RTS) is the analog of TAMIS and represents a new focus for the advancement of transanal platforms robotic transanal surgery is sometimes referred to as robotic TAMIS. Though limited to only a few centers world-wide, experience with robotic transanal surgery has been encouraging. Most research with robotic transanal surgery has concentrated on local excision of rectal neoplasia, although more complex procedures such as transanal proctectomy are possible using the robotic approach. This article reports the surgical technique of R-TAMIS performed in the Brazilian National Cancer Institute (INCA, Rio de Janeiro). Methods: 71-year-old, female with cardiologic disease (heart failure), with a 1.5 cm rectal neoplasm at 4 cm from the anal verge in the right anterolateral position. Biopsy revealed neuroendocrine tumor. A compete colonoscopy revealed no evidence of synchronous lesions. Work-up included 3D endorectal ultrasonography and magnetic resonance imaging, which demonstrated the lesion to be uT1uN0. The patient was counseled about surgical options − local excision versus low anterior resection. Due to the cardiologic condition, the patient was elected to proceed with local excision with robotic transanal surgery. Conclusion: Robotic TAMIS is a safe and effective operative procedure for high selected cases of rectal neoplasm. It enhances surgeon ergonomics and facilitates tumor removal and suture in the transanal approach.


RESUMO Introdução: A cirurgia transanal robótica (RTS,Robotic Transanal Surgery) é análoga da TAMIS (cirurgia minimamente invasiva transanal) e representa um novo foco para o avanço das plataformas transanais. A cirurgia transanal robótica é algumas vezes chamada de TAMIS robótica. Embora limitada a apenas alguns centros em todo o mundo, a experiência com a cirurgia transanal robótica tem sido encorajadora. A maioria das pesquisas com cirurgia transanal robótica tem se concentrado na excisão local da neoplasia retal, embora procedimentos mais complexos, como a proctectomia transanal, sejam possíveis utilizando a abordagem robótica. Este artigo relata a técnica cirúrgica de R-TAMIS realizada no Instituto Nacional do Câncer (INCA, Rio de Janeiro). Métodos: paciente de 71 anos, sexo feminino, com doença cardiológica (insuficiência cardíaca), com neoplasia retal de 1,5 cm a 4 cm da borda anal em posição anterolateral direita. A biópsia revelou tumor neuroendócrino. Uma colonoscopia completa não revelou evidências de lesões sincrônicas. A investigação incluiu ultrassonografia endorretal em 3D e ressonância magnética, que demonstrou que a lesão era uT1uN0. A paciente foi aconselhada sobre as opções cirúrgicas - excisão localversus ressecção anterior baixa. Devido à condição cardiológica, optou-se por proceder à excisão local com cirurgia transanal robótica. Conclusão: A TAMIS robótica é um procedimento cirúrgico seguro e eficaz para casos altamente selecionados de neoplasia retal. Ela melhora a ergonomia do cirurgião e facilita a remoção do tumor e a sutura na abordagem transanal.

ABSTRACT

Abstract Myasthenia Gravis (MG) is an autoimmune disease characterized by weakness and fatigability of skeletal muscles, with improvement following rest. It is a disease of great significance to the anesthesiologist because it affects the neuromuscular junction. Robotic thymectomy has come up in recent times due to the minimally invasive nature and its advantages. This presents a new set of challenges for the anesthesia team, and here we present the various anesthesia considerations and perioperative management in a series of 20 patients who underwent robotic thymectomy. As it is a recent upcoming procedure, there is a paucity of literature on this topic, and most of the available literature talks about One-Lung Ventilation (OLV) and thoracic epidurals. To our notice, this is the first literature without the use of OLV and thoracic epidural for the management of robotic thymectomy.


Resumo Miastenia Gravis (MG) é uma doença autoimune que se caracteriza por fraqueza e fadiga da musculatura esquelética, com melhora após o repouso. É uma doença de grande interesse para o anestesiologista, pois compromete a junção neuromuscular. Recentemente, a timectomia robótica tem sido empregada por apresentar as vantagens da abordagem minimamente invasiva. O procedimento introduz uma série de novos desafios para a equipe de anestesia. Relatamos aqui as várias considerações anestésicas e o cuidado perioperatório em uma série de 20 pacientes submetidos a timectomia robótica. Sendo um procedimento recente, há limitada literatura discutindo esse tópico e, além disso, a maior parte da literatura disponível concentra a atenção na Ventilação Monopulmonar (VMP) e na peridural torácica. A nosso ver, este é a primeiro relato na literatura sem o emprego de VMP e peridural torácica para o manejo da timectomia robótica.

ABSTRACT

ABSTRACT Purpose: The conservative management of localized renal masses has been recently widened to cT2 tumors showing encouraging functional and oncological outcomes (1). This video aims to report the conservative management of a highly complex renal tumor treated with robotic pure enucleation in our center, specifically focusing on preoperative work-up, video-reported surgical steps and perioperative outcomes. Materials and Methods: A 63 year-old lady underwent CT scan revealing a single 75 x 68mm, mainly endophytic, right renal mass dislocating the vascular pedicle (cT3a). Two renal arteries and two veins were identified. PADUA, RENAL and simplified SPARE scores were 14a, 12a and 12 respectively. Since the contralateral kidney was hypotrophic, the indication for nephron-sparing approach was considered absolute. Preoperative surgical planning included the employment of 3D-virtual models (2). Results: Operative time was 150 minutes and warm ischemia time was 25 minutes. No major complication occurred. Histopathological analysis revealed a cromophobe renal cell carcinoma with extension to perirenal fat tissue (pT3a). Resection technique was classified as pure enucleation since Surface-Intermediate-Base (SIB) score was 0-0-0 (3, 4). At seven-months follow-up no signs of local or systemic recurrence were recorded. Postoperative CT-scan revealed optimal parenchymal volume preservation with last creatinine blood level of 1.16mg/dL. Conclusion: This video highlights how, in experienced hands, robotic partial nephrectomy represents a feasible, effective treatment option for surgical management of highly complex renal tumors. The employment of intraoperative ultrasonography and 3D-virtual models allowed to accurately tailor surgical approach, improving the perception of tumor anatomy and its vascularization and maximizing perioperative outcomes.

ABSTRACT

ABSTRACT Known laparoscopic and robotic assisted approaches and techniques for the surgical management of urological malignant and benign diseases are commonly used around the World. During the global pandemic COVID-19, urology surgeons had to reorganize their daily surgical practice. A concern with the use of minimally invasive techniques arose due to a proposed risk of viral transmission of the coronavirus disease with the creation of pneumoperitoneum. Due to this, we reviewed the literature to evaluate the use of laparoscopy and robotics during the pandemic COVID-19. A literature review of viral transmission in surgery and of the available literature regarding the transmission of the COVID-19 virus was performed up to April 30, 2020. We additionally reviewed surgical society guidelines and recommendations regarding surgery during this pandemic. Few studies have been performed on viral transmission during surgery. No study has been made regarding this area during minimally invasive urology cases. To date there is no study that demonstrates or can suggest the ability for a virus to be transmitted during surgical treatment whether open, laparoscopic or robotic. There is no society consensus on restricting laparoscopic or robotic surgery. However, there is expert consensus on modification of standard practices to minimize any risk of transmission. During the pandemic COVID-19 we recommend the use of specific personal protective equipment for the surgeon, anesthesiologist and nursing staff in the operating room. Modifications of standard practices during minimally invasive surgery such as using lowest intra-abdominal pressures possible, controlled smoke evacuation systems, and minimizing energy device usage are recommended.

ABSTRACT

RESUMO A infecção pelo coronavírus determinante da doença COVID-19, também conhecida como SARS-COV2 foi classificada nos últimos meses como pandemia. Essa é potencialmente fatal, representando enorme problema de saúde mundial. A disseminação, após provável origem zoonótica na cidade de Wuhan, China, resultou em colapso do sistema de saúde de diversos países, alguns com enorme impacto social e número grande de mortes descritas na Itália e Espanha. Medidas extremas intra e extra-hospitalares têm sido implementadas a fim de conter a transmissão e disseminação da COVID-19. No âmbito cirúrgico, enorme quantidade de procedimentos considerados não essenciais ou eletivos foram prorrogados ou suspensos até resolução da pandemia. No entanto, cirurgias de urgência e oncológicas não permitem que o paciente espere. Nesta publicação, sugerimos e ensinamos adaptação a ser feita com materiais de uso corriqueiro em laparoscopias para evitar a contaminação ou a disseminação entre as equipes assistenciais e os pacientes.


ABSTRACT The coronavirus infection, also known as SARS-COV2, has proven to be potentially fatal, representing a major global health problem. Its spread after its origin in the city of Wuhan, China has resulted in a pandemic with the collapse of the health system in several countries, some with enormous social impact and expressive number of deaths as seen in Italy and Spain. Extreme intra and extra-hospital measures have been implemented to decrease the transmission and dissemination of the COVID-19. Regarding the surgical practice, a huge number of procedures considered non-essential or elective were cancelled and postponed until the pandemic is resolved. However, urgent and oncological procedures have been carried out. In this publication, we highlight and teach adaptations to be made with commonly used materials in laparoscopy to help prevent the spread and contamination of the healthcare team assisting surgical patients.

ABSTRACT

ABSTRACT Objectives: described by Dr. Jorge Daes, principles of the enhanced view totally extraperitoneal (eTEP) has been widely used in the armamentarium of ventral hernia repair recently. Robotic assisted eTEP technique feasibility has been proved, however, a complete understanding of retromuscular abdominal wall planes and its landmarks still uncertain in a majority of general surgeons. The aim of this report is to propose a technical standardization and its anatomic concepts in the robotic-assisted eTEP ventral hernia repair. Methods: our group describes 10 key steps in a structured step-by-step approach for a safe and reproducible repair based on well defined anatomic landmarks, identification of zones of dissection and correct restoration of the linea alba. Results: the standardization has been developed 2 years ago and applied to all patients. A robotic-assisted surgery with 3 robotic arms is performed in a lateral docking setup. Feasibility is established and reproducibility is high among general surgeons. Conclusion: we present a standardized side docking robotic assisted eTEP approach for ventral hernia repairs with 10 key steps. We believe understanding the landmarks and a step-by-step guidance based on the concepts of retromuscular abdominal wall anatomy foment a safe learning of minimally invasive restoration of the abdominal wall integrity regarding non-expert surgeons.


RESUMO Objetivo: descritos pelo Dr. Jorge Daes, os princípios da visão aprimorada totalmente extraperitoneal (eTEP) têm mais recentemente sido utilizados no arsenal de reparos de hérnias ventrais. A realização da técnica de reparo totalmente extraperitoneal com o uso da robótica mostrou-se viável. No entanto, o verdadeiro conhecimento dos planos da parede abdominal retromuscular e os referenciais ainda são incertos para a maioria dos cirurgiões gerais. O objetivo deste artigo é propor padronização técnica e conceitos anatômicos no reparo de hérnia ventral robótico totalmente extraperitoneal (eTEP VHR). Métodos: nosso artigo descreve 10 etapas essenciais em abordagem estruturada passo a passo para procedimento seguro e reprodutível com base em referenciais anatômicos bem definidos, identificação de zonas de dissecção e restauração correta e completa da linha alba. Resultados: a padronização foi desenvolvida há 2 anos e aplicada a todos os pacientes. A cirurgia robótica é realizada com três braços da plataforma e por docking lateral. Conforme descrita, a reprodutibilidade e segurança são altas entre os cirurgiões gerais. Conclusão: apresentamos abordagem padronizada da técnica robótica de reparo de hérnia ventral totalmente extraperitoneal (eTEP VHR) em docking lateral por meio de 10 etapas essenciais. Acreditamos que a compreensão dos referenciais anatômicos e orientação passo a passo com base nos conceitos da anatomia do espaço retromuscular fomentam o aprendizado seguro, na atuação de cirurgiões não experientes durante a restauração minimamente invasiva da integridade da parede abdominal.

ABSTRACT

ABSTRACT Objective: To evaluate the results of resection of tumors of the thymus by robotic thoracic surgery, analyzing the extent of resection, postoperative complications, time of surgery, and length of stay. Methods: Retrospective study from a database involving patients diagnosed with a tumor of the thymus and undergoing robotic thoracic surgery at one of seven hospitals in Brazil between October of 2015 and June of 2018. Results: During the study period, there were 18 cases of resection of tumors of the thymus: thymoma, in 12; carcinoma, in 2; and carcinoid tumor, in 1; high-grade sarcoma, in 1; teratoma, in 1; and thymolipoma, in 1. The mean lesion size was 60.1 ± 32.0 mm. Tumors of the thymus were resected with tumor-free margins in 17 cases. The median (interquartile range) for pleural drain time and hospital stay, in days, was 1 (1-3) and 2 (2-4), respectively. There was no need for surgical conversion, and there were no major complications. Conclusions: Robotic thoracic surgery for resection of tumors of the thymus has been shown to be feasible and safe, with a low risk of complications and with postoperative outcomes comparable to those of other techniques.


RESUMO Objetivo: Avaliar os resultados da ressecção de tumores tímicos por cirurgia torácica robótica, verificando a radicalidade da ressecção, complicações pós-operatórias, tempo de cirurgia e tempo de internação. Métodos: Estudo retrospectivo a partir de um banco de dados envolvendo pacientes com diagnóstico de tumor tímico e submetidos à cirurgia torácica robótica em sete hospitais no Brasil entre outubro de 2015 e junho de 2018. Resultados: Durante o período estudado, houve 18 casos de ressecção de tumores tímicos (timomas, em 12; carcinoma tímico, em 2; e tumor carcinoide tímico, sarcoma tímico de alto grau, teratoma tímico e timolipoma, em 1 cada). A média do tamanho das lesões foi de 60,1 ± 32,0 mm. Tumores tímicos foram ressecados com margens livres em 17 casos. As medianas (intervalos interquartis) de tempo de dreno pleural e de internação, em dias, foram 1 (1-3) e 2 (2-4), respectivamente. Não houve necessidade de conversão cirúrgica nem complicações maiores. Conclusões: A cirurgia torácica robótica para a ressecção de tumores tímicos demonstrou ser factível e segura, com baixo risco de complicações e desfechos pós-operatórios comparáveis aos de outras técnicas.

ABSTRACT

ABSTRACT Objective: the first robotic pancreatic resection in Brazil was performed by our team in 2008. Since March 2018, a new policy prompted us to systematically employ the robot in all minimally invasive pancreatic surgery. The aim of this paper is to review our experience with robotic pancreatic resection. Methods: all patients who underwent robotic pancreatic resection from March 2018 through December 2019 were identified. Descriptive data were collected. Preoperative variables included age, sex, and indication for surgery. Intraoperative variables included operative time, bleeding, blood transfusion. Results: 105 patients underwent robotic pancreatectomy. Median age was 60.5 years old. Fifty-five patients were female. 51 patients underwent robotic pancreatoduodenectomies, 34 distal pancreatectomy. Morbidity was 23.8%, mainly related to postoperative pancreatic fistula and one death occurred (mortality of 0.9%). Three patients (2.8%) were converted to open surgery. Four patients had delayed gastric emptying and two presented bleeding. Twenty-four patients had pancreatic fistula that was treated conservatively with late removal of the pancreatic drain. No patient required percutaneous drainage, reintervention or hospital readmission. Conclusions: the robotic platform is useful for the reconstruction of the alimentary tract after pancreatoduodenectomy or after central pancreatectomy. It may increase the preservation of the spleen during distal pancreatectomies. Pancreas sparing techniques, such as enucleation, resection of uncinate process and central pancreatectomy, should be used to avoid exocrine and/or endocrine insufficiency. Robotic resection of the pancreas is safe and feasible for selected patients. It should be performed in specialized centers by surgeons with experience in both open and minimally invasive pancreatic surgery.


RESUMO Objetivo: a primeira ressecção pancreática robótica no Brasil foi realizada por nossa equipe em 2008. Desde março de 2018, uma nova política nos levou a empregar sistematicamente o robô em todas cirurgias pancreáticas minimamente invasivas. O objetivo deste artigo é revisar nossa experiência com a ressecção pancreática robótica. Métodos: todos os pacientes submetidos a ressecção pancreática robótica de 2018 a 2019 foram incluídos. Variáveis pré- e intraoperatórias como idade, sexo, indicação, tempo cirúrgico, sangramento, diagnóstico, tamanho do tumor foram analisados. Resultados: 105 pacientes foram submetidos a pancreatectomia robótica. A idade mediana dos pacientes foi de 60,5 anos. 55 pacientes eram do sexo feminino. 51 pacientes foram submetidos a pancreatoduodenectomia, 34 pancreatectomia distal. A morbidade foi de 23,8% e ocorreu um óbito (mortalidade de 0,9%). Três pacientes (2,8%) tiveram a operação convertida para aberta. Quatro pacientes apresentaram retardo no esvaziamento gástrico e dois apresentaram sangramento. Vinte e quatro pacientes apresentaram fístula pancreática tratada de forma conservadora com remoção tardia do dreno pancreático. Nenhum paciente necessitou de drenagem percutânea, reintervenção ou readmissão hospitalar. Conclusões: a plataforma robótica é útil para a reconstrução do trato alimentar após pancreatoduodenectomia ou após pancreatectomia central. Pode aumentar a preservação do baço durante pancreatectomias distais. Técnicas poupadoras de pâncreas, como enucleação, ressecção de processo uncinado e pancreatectomia central, devem ser usadas para evitar insuficiência exócrina e/ou endócrina. A ressecção robótica do pâncreas é segura e viável para pacientes selecionados. Deve ser realizada em centros especializados por cirurgiões com experiência em cirurgia pancreática aberta e minimamente invasiva.

El robot permite trasladar la técnica quirúrgica abierta a un abordaje mínimamente invasivo, con acceso por boca, para patología benigna y maligna. Actualmente se emplean diferentes terapéuticas con similares resultados oncológicos. Objetivo: introducir una herramienta quirúrgica para abordaje bucal. Comunicar la experiencia inicial con el uso del robot. Evaluar la preservación de respiración y deglución. Analizar variables que determinaron una disminución en la hospitalización. Material y métodos: 13 mujeres y 11 hombres. Edad entre 16 y 82 años, media de 55,08. Total 24 pacientes con enfermedad inflamatoria crónica (8), tumores benignos (4) y malignos (12). Variables consideradas en cirugía robótica: tiempo y lugar de internación, complicaciones, estado respiratorio y deglutorio, uso de técnicas reconstructivas. Se realizó videoendoscopia de deglución para objetivar la seguridad del método. Resultados: tiempo medio de internación: 1,92 días. El 83,3% internado 1 día. El 79,9% en internación general. Unidad cerrada: 20,1%. Ninguna traqueostomía. Cicatrización del lecho por segunda. Sin complicaciones. Edema de lengua: 2 pacientes. Conclusiones: la cirugía robótica favorece la exéresis con baja morbilidady máxima preservación de tejidos sanos. Disminuye: edema posoperatorio, uso colgajos para reparar el lecho, traqueotomía temporaria, tiempo de internación. La videoendoscopia de deglución demuestra utilidad para determinar la deglución segura. Limitante del presente trabajo es el tamaño de la muestra. Es importante incrementar el número de pacientes para valorizar supervivencia y calidad de vida.


Background: robotic surgery is an alternative to open surgery, CO2 laser microsurgery, or chemoradiation for the upper aero-digestive tract. This system allows surgeons to use the open surgical technique in a minimally invasive approach through the mouth to treat benign and malignant disorders. Different treatments are currently used with similar oncologic outcomes. Objective: the aim of this study was to introduce a surgical tool through transoral approach, report the initial experience with the use of the robotic system, evaluate respiratory and digestive functional preservation and analyze the variables associated with shorter hospital length of stay. Material and methods: A total of 24 patients (13 women and 11 men, mean age 55.08 years [16-82]) were included. Eight patients had chronic inflammatory disease, four had benign tumors and 12 had cancer. The variables considered in robotic surgery were hospital length of stay, place of postoperative care, complications, respiratory and swallowing function and use of reconstructive techniques. Flexible endoscopic evaluation of swallowing was performed to document safe function. Results: mean length of stay was 1.92 days; 83.3% stayed for one day; 79.9% were admitted to the general ward and 20.1% stayed in intensive or intermediate care units. None of the patients required tracheostomy. Healing of the surgical bed occurred by secondary intention. There were no complications. Tongue edema occurred in two patients. Conclusions: robotic surgery favors tumor removal with low morbidity and maximum preservation of healthy tissues while reducing postoperative edema, use of flaps for reconstruction, temporary tracheostomy and hospital length of stay. Flexible endoscopic evaluation of swallowing is useful to determine safe swallowing function. The main limitation of our study is the sample size. It is important to increase the number of patients to evaluate survival and quality of life.

ABSTRACT

OBJECTIVES: The enhanced recovery after surgery (ERAS) protocol recommends prevention of intraoperative hypothermia. However, the beneficial effect of maintaining normothermia after radical cystectomy has not been evaluated. This study aimed to investigate the efficacy of fluid warming nursing in elderly patients undergoing Da Vinci robotic-assisted laparoscopic radical cystectomy. METHODS: A total of 108 patients with bladder cancer scheduled to undergo DaVinci robotic-assisted laparoscopic radical cystectomy were recruited and randomly divided into the control group (n=55), which received a warming blanket (43°C) during the intraoperative period and the warming group (n=53), in which all intraoperative fluids were administered via a fluid warmer (41°C). The surgical data, body temperature, coagulation function indexes, and postoperative complications were compared between the two groups. RESULTS: Compared to the control group, the warming group had significantly less intraoperative transfusion (p=0.028) and shorter hospitalization days (p<0.05). During the entire intraoperative period (from 1 to 6h), body temperature was significantly higher in the warming group than in the control group. There were significant differences in preoperative fibrinogen level, white blood cell count, total bilirubin level, intraoperative lactose level, postoperative thrombin time (TT), and platelet count between the control and warming groups. Multivariate linear regression analysis demonstrated that TT was the only significant factor, suggesting that the warming group had a lower TT than the control group. CONCLUSION: Fluid warming nursing can effectively reduce transfusion requirement and hospitalization days, maintain intraoperative normothermia, and promote postoperative coagulation function in elderly patients undergoing Da Vinci robotic-assisted laparoscopic radical cystectomy.

ABSTRACT

OBJETIVO: Describir los resultados clínicos postoperatorios tempranos de la primera serie de pacientes operados de artroplastía total de rodilla (ATR) con asistencia de brazo-robótico en Latinoamérica. MATERIALES Y MÉTODOS: Estudio prospectivo de 52 pacientes (53 rodillas) con gonartoris tricompartimental sintomática operados de ATR primaria con asistencia de brazo-robótico (RIO-MAKO) de manera consecutiva, con seguimiento a 2 meses postoperados. No se excluyeron pacientes. Se utilizó el mismo protocolo anestésico y de rehabilitación. Se realizó revisión de fichas clínicas para recolectar los siguientes resultados: tiempo de isquemia quirúrgica, estadía hospitalaria, tiempo a marcha, dolor postoperatorio diario [Escala visual análoga (EVA)], uso de opioides, rangos de movilidad articular (ROM), pérdida sanguínea, complicaciones y eje mecánico postoperatorio. RESULTADOS: Tiempos de Isquemia: 82 minutos (60­120). Estadía Hospitalaria: 4 días (2­12). Dolor postoperatorio: EVA el mismo día operatorio de 0 (0­10) y previa al alta de 0 (rango 0­4), con 0,3 purgas (0­6,5) de opioides por paciente. Tiempo a marcha (día logrado): 1 día (1­3), cuarenta y cinco pacientes (84,9%) iniciaron la marcha el primer día postoperatorio. ROM (Extensión-Flexión): Aumento progresivo durante el seguimiento. En el control ambulatorio de los dos primeros meses [23 días (13­50)], veintiún pacientes (40%) alcanzaron un ROM mayor o igual a 0­90° y once (20%) presentaron un ROM funcional máximo (0­120°). Pérdida sanguínea: Siete pacientes (13,2%) requirieron transfusión. Complicaciones: un paciente (1,89%) presentó una dehiscencia del cierre de la artrotomía. No hubo otras complicaciones. Eje mecánico postoperatorio: 179,1° (178,2­180). DISCUSIÓN: Los resultados concuerdan con la evidencia descrita en otras regiones, sugiriendo que la asistencia de brazo-robótico permite resultados postquirúrgicos reproducibles. CONCLUSIÓN: Los resultados clínicos postoperatorios tempranos de esta serie de pacientes operados de ATR con asistencia de brazo-robótico, muestran una baja percepción del dolor, con bajo consumo de opioides, una rápida recuperación funcional de la marcha y ROM, y excelentes resultados desde el punto de vista del eje mecánico postoperatorio. NIVEL DE EVIDENCIA: IV.


OBJECTIVE: Describe the early clinical postoperative outcomes, of the first series of patients operated on Robotic Arm-Assisted Total Knee Arthroplasty (TKA) in Latin America. MATERIAL AND METHOD: Retrospective study including 52 patients (53 knees) with advanced symptomatic knee osteoarthritis, consecutively operated on Robotic ArmAssisted TKA (RIO-MAKO) during October 2018 and May 2019 with two months of follow-up. No patients were excluded from the study. The same anesthetic and rehabilitation protocol was followed for all patients. Data were obtained from the clinical files for the following outcomes: Surgical tourniquet time, hospital stay, time to walk, postoperative daily pain [Visual Analog Scale (VAS)], opioid consumption, range of motion (ROM), blood loss, complications, and the attained postoperative mechanical axis. RESULTS: Tourniquet Time: 82 minutes (60­120). Hospital Stay: 4 days (2­12). Postoperative Pain: VAS of 0 (0­10) the same day of surgery, and 0 (0­4) before discharge. The opioid consumption was 0,3 purge (0­6,5) per patient. Time to Walk (Day achieved): 1st day (1­3), forty-five patients (84,9%) walked on their first postoperative day. ROM (Extension-Flexion): progressively increases during the follow up. On the first two-month visits [23 days (13­50)], twenty-one patients (40%) reached a ROM equal or superior to 0­90°, and eleven (20%) presented a maximal functional ROM (0­120°). Blood Loss: Seven patients (13.2%) required a blood transfusion. Complications: one patient (1.89%) presented dehiscence of the arthrotomy closure. No other complications were registered. Postoperative Mechanical Axis: 179.1° (178.2­180). DISCUSSION: The results coincide with the reported evidence from other regions. Robotic-arm assistance may generate reproducible postoperative results. CONCLUSIONS: The early postoperative clinical results of this series of patients operated on Robotic Arm-Assisted TKA show a low pain perception and opioid use, a rapid functional rehabilitation in terms of gait and ROM, and excellent postoperative mechanical alignment. LEVEL OF EVIDENCE: IV.

ABSTRACT

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

ABSTRACT

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

ABSTRACT

Background Robot-assisted minimally invasive heart surgery is an effective alternative when compared with classical approaches. It has a low mortality and postoperative complications and its long-term durability is comparable with conventional techniques. Aim: To report short- and long-term results with the use of a robot-assisted transthoracic approach. Patients and Methods: Review of patients undergoing heart surgery between 2015 and 2019 using a robot assisted minimally invasive technique in a single center. We analyzed demographic characteristics, surgical and early ultrasound results. Results: Thirteen procedures were reviewed, nine mitral valve repairs (MVR) in patients aged 61 ± 21 years (seven males) and four atrial septal defect (ASD) closures in patients aged from 24 to 52 years (three men). For MVR, the average extracorporeal circulation and myocardial ischemia times were 120 ± 20.9 and 89 ± 21 minutes, respectively. The median hospitalization was four days. Two cases of MVR had postoperative complications. There was no mortality. All cases showed improvement in their symptoms. Ultrasound findings showed no postoperative mitral insufficiency except in one case. Conclusions: We report very good results in both complex mitral repair and CIA closure, comparable to centers with high standards in minimally invasive robot-assisted heart surgery.
