RESUMO
BACKGROUND: The da Vinci™ Surgical System, recognized as the leading surgical robotic platform globally, now faces competition from a growing number of new robotic surgical systems. With the expiration of key patents, innovative entrants have emerged, each offering unique features to address limitations and challenges in minimally invasive surgery. The hinotori™ Surgical Robot System (hinotori), developed in Japan and approved for clinical use in November 2022, represents one such entrant. This study demonstrates initial insights into the application of the hinotori in robot-assisted surgeries for patients with rectal neoplasms. METHODS: The present study, conducted at a single institution, retrospectively reviewed 28 patients with rectal neoplasms treated with the hinotori from November 2022 to March 2024. The surgical technique involved placing five ports, including one for an assistant, and performing either total or tumor-specific mesorectal excision using the double bipolar method (DBM). The DBM uses two bipolar instruments depending on the situation, typically Maryland bipolar forceps on the right and Fenestrated bipolar forceps on the left, to allow precise dissection, hemostasis, and lymph node dissection. RESULTS: The study group comprised 28 patients, half of whom were male. The median age was 62 years and the body mass index stood at 22.1 kg/m2. Distribution of clinical stages included eight at stage I, five at stage II, twelve at stage III, and three at stage IV. The majority, 26 patients (92.9%), underwent anterior resection using a double stapling technique. There were no intraoperative complications or conversions to other surgical approaches. The median operative time and cockpit time were 257 and 148 min, respectively. Blood loss was 15 mL. Postoperative complications were infrequent, with only one patient experiencing transient ileus. A median of 18 lymph nodes was retrieved, and no positive surgical margins were identified. CONCLUSIONS: The introduction of the hinotori for rectal neoplasms appears to be safe and feasible, particularly when performed by experienced robotic surgeons. The double bipolar method enabled precise dissection and hemostasis, contributing to minimal blood loss and effective lymph node dissection.

Resumen Introducción: El cáncer colorrectal es la cuarta patología neoplásica en incidencia y mortalidad en Colombia y, aunque hay evidente mejoría en sus desenlaces, este alto volumen hace indispensable la participación integrada de cirujanos colorrectales y cirujanos generales dedicados a esa área de interés. A la fecha es la cirugía el pilar del tratamiento de esta enfermedad, la cual debe ser realizada dentro de unos parámetros que permitan asegurarle al paciente la resección completa de la misma. Uno de estos parámetros incluye un adecuado vaciamiento ganglionar que nos permite evaluar el pronóstico de la enfermedad y la necesidad de terapias complementarias. Objetivo: Evaluar la calidad de la disección ganglionar en la cirugía oncológica colorrectal efectuada por cirujanos generales en dos instituciones de la ciudad de Bogotá. Materiales y Método: Estudio observacional analítico de corte transversal; se analizaron 315 pacientes llevados a cirugía electiva oncológica colorrectal por cirujanos generales en el periodo de 2014 a 2017 en nuestras instituciones. Resultados: La mediana de ganglios linfáticos recuperados fue de 16, el número de ganglios disecados se asoció con localización del tumor (p = 0,002) y la neoadyuvancia (p = 00,001). Sin embargo, no se encontró asociación con el sexo, tipo de abordaje y volumen de sangrado. Conclusiones: Las colectomías realizadas por cirujanos generales mantienen un volumen óptimo en relación a la disección ganglionar sin comprometer el resto de los desenlaces. El número de ganglios linfáticos recuperados se asoció con la localización del tumor y la terapia neoadyuvante.
Introduction: Colorectal cancer is the 4th neoplastic disease in terms of incidence and mortality in Colombia, even though the clinical outcomes are improving. The high volume of this patients is requesting the collaboration between colorectal surgeons and general surgeons dedicated to this area of interest. To date is surgery the mainstay of the treatment of this disease which should be carried out within parameters that allow to assure the patient the complete resection of the lesion. One of these parameters includes a suitable lymph node emptying that allows us to evaluate the prognosis of the disease and the need of complementary therapies. Aim: To evaluate the quality of the lymph node dissection in colorectal surgery performed by general surgeons in two academic institutions in Bogota, Colombia. Materials and Method: Transversal cohort in analytical and observational study. We analyzed 315 patients scheduled for elective colorectal surgery by general surgeons in the period from 2014 to 2017 in our institutions. Results: The mean of the lymph node recovered was 16, the number of dissected lymph nodes was associated with the tumor location (p = 0.002), and the neoadjuvant (p = 0.001). However, no association within sex, approach and bleeding was found. Conclusions: The colectomies performed by general surgeons maintain an optimal volume in relation with lymph node dissection without affect the remaining clinical outcomes. The number of lymph nodes recovered is associated with tumor location and neoadjuvant therapy.

INTRODUÇÃO: Há um grande empenho na busca por soluções reconstrutivas para as áreas de perda cutânea ou muscular que exijam cobertura ou preenchimento cavitário estável. O retalho anterolateral da coxa, descrito na China por Song et al. (1984), é considerado por muitos como o retalho ideal nas grandes reconstruções. OBJETIVO: Relatar a aplicabilidade do retalho anterolateral da coxa como recurso versátil nas reconstruções da parede abdominal. MÉTODOS: Dois pacientes foram selecionados para serem submetidos à ressecção tumoral de cólon direito com invasão da parede abdominal pela equipe de cirurgia oncológica em conjunto com a equipe de cirurgia plástica, que foi a responsável pela reconstrução da parede abdominal. Em ambos os casos, utilizou-se o retalho anterolateral da coxa pediculado, que foi transposto para o defeito após a ressecção parcial da parede abdominal no mesmo tempo cirúrgico. Entre as vísceras abdominais e o retalho, foi fixada tela de PROCEEDTM para reforço da parede abdominal. Resultados: Ambos os pacientes tiveram boa evolução pós-operatória e encontram-se em acompanhamento, sem sinais de recidiva tumoral e com boa qualidade de vida. CONCLUSÃO: O retalho anterolateral da coxa mostrou-se recurso útil dentro do arsenal terapêutico reconstrutivo da parede abdominal devido a grandes ressecções tumorais em oncologia.
INTRODUCTION: There is a strong commitment in pursuing reconstructive solutions for areas of skin or muscular loss that require covering or stable cavity filling. The anterolateral thigh flap, described in China by Song et al. (1984), is considered by many as the optimal flap in large reconstructions. OBJECTIVE: To report the applicability of the anterolateral thigh flap, as a versatile resource in reconstructions of the abdominal wall. METHODS: Two patients were submitted to tumoral resection of the right colon with invasion of the abdominal wall by a team of oncologic surgeons in conjunction with the plastic surgery team that was responsible for the reconstruction of the abdominal wall. In both cases, the pedicled anterolateral thigh flap was used, which was transposed to the defect after partial resection of the abdominal wall at the same surgical time. A PROCEEDTM surgical mesh was fixed between the abdominal viscera and the flap to reinforce the abdominal wall. RESULTS: Both patients had good postoperative evolution and are in follow-up, with no signs of tumor recurrence and with a good quality of life. CONCLUSION: The anterolateral thigh flap is a useful resource for the reconstruction of the abdominal wall due to large tumor resections in oncology.

Exenteração pélvica é o tratamento cirúrgico radical para diferentes neoplasias pélvicas malignas. Consiste na retirada de todos os órgãos comprometidos pelo câncer, incluindo margens livres de doença. Recidivas ou persistências de tumor maligno na pelve após tratamento radioquimioterápico são a principal indicação, mas pode também ser o tratamento primário do câncer ginecológico localmente avançado. O procedimento apresenta mortalidade perioperatória de 5 a 10% e morbidade média de 50%. As complicações mais relatadas são fístulas intestinais e urinárias, infecções de sítio cirúrgico e fenômenos tromboembólicos. A sobrevida em 5 anos varia de 30 a 70%, com média de 50% nas maiores séries. Os critérios prognósticos mais importantes são, além da ressecção total ?R0? do tumor com margens cirúrgicas livres, a presença de metástases linfonodais, sobretudo extrapélvicas, e o comprometimento de parede pélvica lateral. Idade e índice de massa corpórea não devem ser considerados como fatores de risco isolados. A exenteração pélvica com intuito paliativo, apesar de indicação ainda discutível, pode ser considerada para alívio da sintomatologia local e consequente melhora na qualidade de vida. Portanto, quando realizada em pacientes cuidadosamente selecionadas, em instituições oncológicas com suporte multidisciplinar, pode oferecer controle da neoplasia pélvica em longo prazo.(AU)
Pelvic exenteration is a radical surgical treatment indicated as the treatment various malignant pelvic neoplasms. It consists of the removal of all organs affected by cancer, including diseasefree margins. treatment are the main indications, but it can also be the primary treatment of locally advanced gynecologic cancer. The procedure presents perioperative mortality of 5 to 10% and an average morbidity of 50%. The most commonly reported complications are intestinal and urinary fistulas, surgical site infections and thromboembolic phenomena. The 5-year survival ranges from 30 to 70%, averaging 50% in the larger series. The most important prognostic criteria are, in addition to the total ?R0? resection of the tumor with free surgical margins, the presence of lymph node metastases, especially extrapelvic, and the affection of the lateral pelvic wall. Age and body mass index should not be considered as isolated risk factors. Pelvic exenteration with palliative intent, although still a debatable indication, may be considered for relief of local symptoms and consequent improvement in quality of life. Therefore, when performed in carefully selected patients in oncological institutions with multidisciplinary support, it can provide the control of pelvic neoplasm in the long term.(AU)
