RESUMO
AIM: The aim of this work was to compare lymph node (LN) yield in patients operated on for right colon cancer (RCC) using a laparoscopic approach between those receiving an intracorporeal (ICA) or extracorporeal anastomosis (ECA). METHOD: This is a retrospective multicentre study involving patients operated on for RCC in nine tertiary referral centres in Latin America during a 2-year period. The main comparative outcome between groups was the number of LNs harvested between groups. RESULTS: The study included 416 patients, 261 (62.7%) in the ECA group and 155 (37.3%) in the ICA group. Patients in the ECA group were elderly (66 vs. 61 years, p < 0.001). Patients receiving an ICA achieved a significantly higher LN yield than those receiving an ECA (24 vs. 18, p < 0.001). This group also had a lower percentage of patients achieving a substandard LN yield (<12 LNs) (10% vs. 24.8%, p = 0.001) and more patients achieving a high number of harvested LNs (>32 LNs) (15.5% vs. 8.3%, p = 0.039). In the multivariate analysis, ICA was independently related to the primary outcome (LN yield) (OR 3.28, p = 0.027, 95% CI 1.14-9.38). CONCLUSION: In this retrospective study, patients operated on for RCC who received an ICA achieved a higher LN yield. Further studies are needed to reconfirm these findings, and also to find an explanation for these results.

Background and Objectives: Robotic surgical systems have rapidly become integrated into colorectal surgery practice in recent years, particularly for rectal resections, where the advantages of robotic platforms over conventional laparoscopy are more pronounced. However, as with any technological advancement, the initial high costs can be a limiting factor, leading to unequal health service access, especially in middle- and lower-income countries. Materials and Method: A narrative review was conducted with the objective of providing an overview of the escalating adoption, current training programmes, and certification process of robotic colorectal surgery in Brazil. Results: Brazil has witnessed a rapid increase in robotic platforms in recent years. Currently, there are 106 robotic systems installed nationwide. However, approximately 60% of the medical facilities which adopted robotic platforms are in the Southeast region, which is both the most populous and economically prosperous in the country. The Brazilian Society of Coloproctology recently established clear rules for the training programme and certification of colorectal surgeons in robotic surgery. The key components of the training encompass theoretical content, virtual robotic simulation, observation, assistance, and supervised procedures in colorectal surgery. Although the training parameters are well established, no colorectal surgery residency programme in Brazil has yet integrated the teaching and training of robotic surgery into its curriculum. Thus far, the training process has been led by private institutions and the industry. Conclusion: Despite the fast spread of robotic platforms across Brazil, several challenges still need to be addressed to democratise training and promote the widespread use of these platforms. It is crucial to tackle these obstacles to achieve greater integration of robotic technology in colorectal surgery throughout the country.

Minimally invasive surgery represented a significant milestone in modern surgery; however, continuous innovation and the emergence of new technologies pose new challenges in terms of surgical learning curves since new interventions are associated with increased surgical complexity and a higher risk of complications. For this reason, surgeons are aware of the beneficial effects of "learning before doing" and the importance of safely implementing new surgical procedures in order to obtain better patient outcomes. Considered the largest Latin American training center in minimally invasive surgery, IRCAD Barretos, São Paulo, Brazil, makes it possible to acquire surgical skills through training in different and the most complex areas of medicine, providing the experience of real and simulated situations, with focus on innovation. The center possesses state-of-the-art infrastructure and technology, with a very high-level teaching staff and an affectionate and hospitable reception. Since its inauguration, in 2011, the center has already qualified numerous professionals and has placed the country in a privileged position in terms of surgical knowledge. The present article describes the activities developed over these ten years of the institute in Brazil as the largest training center for surgeons of the continent in order to address the importance of surgical skills training.

In the past 20 years, colorectal surgery has experienced important advances as a result of new technologies that have increasingly transformed conventional open surgery into maximal usage of minimally invasive approaches. While many tools are being developed to change the way that operations are being performed, quality must not suffer. We describe here some of the aspects to pursue to achieve optimal and safe outcomes while utilizing minimally invasive techniques such as robotic surgery, transanal total mesorectal excision, as well as the role of immunofluorescence.
RESUMO
BACKGROUND AND OBJECTIVE: Rectal cancer is often surgically treated, but it is still associated with morbidity rates. Minimally invasive techniques are increasingly being used to reduce complications, and the use of such techniques can be found in the literature. This study aims to report our experience in a reference oncology center. METHODS: A retrospective cohort study was performed on a prospective database of patients who underwent robotic surgery for rectal cancer using the single-docking technique from September 2014 to April 2018. Clinical and surgical variables, as well as morbidity and mortality rates, were analyzed. RESULTS: One hundred and two patients underwent robotic surgery. Intraoperative complications occurred in six patients (4.9%), and postoperative complications in 24 patients (23.5%), of which anastomotic fistula represented 3.9%. The conversion rate was 1.96%. Two cases (1.9%) faced death within 30 days. The median length of hospitalization was 3 days. The median number of lymph nodes dissected was 15. Clinical and surgical data were correlated with postoperative complications, and no statistically significant differences were found. CONCLUSION: Robotic surgery is a safe and feasible approach to manage rectal cancer. The method presents satisfactory results with regard to the rate of operative complications, conversion rate, oncologic outcomes, and length of hospitalization.

OBJECTIVE: to appraise the general profile of the Brazilian robotic surgeon and the acknowledgment of the new certification process for robotic surgery upon the Associação Médica Brasileira (AMB - Brazilian Medical Association) statement. According to the AMB statement, medical societies and proctors have to achieve leading roles in training and certification of surgeons, acting in partnership with industry. METHODS: a national web-based survey was promoted by the Colégio Brasileiro de Cirurgiões (CBC - Brazilian College of Surgeons) among their members. RESULTS: the 294 answers were split into two groups: 133 (45.3%) who had robotic console certification, and 161 (54.8%) who did not have it. The overall median age was 46, but the non-robotic group presented more surgeons with at least 30 years of experience than to the robotic group (32.3% versus 23.3%, p=0.033). Surgeons with robotic certification more frequently work in a city with at least one million inhabitants than surgeons who were not certified (85.7 versus 63.4%, p<0.001). The majority of surgeons in both groups have similar positioning for all main points of the statement. However, the agreement proportions for the preceptors responsibility during the procedures were higher among non-robotic surgeons that expected the preceptor to assume co-responsibility for the procedure (85% versus 60.9%, p<0.001), and intervene during the procedure as much as necessary (97.5% versus 91.7%, p=0.033). CONCLUSION: the overall agreement of the answers to the AMB statement seems to be a promising pathway to increase the participation of the medical entities into the robotic certification in Brazil.

With the expansion of robotic surgical procedures, the acquisition of specific knowledge and skills for surgeons to reach proficiency seems essential before performing surgical procedures on humans. In this sense, the authors present a proposal to establish a certification based on objective and validated criteria for carrying out robotic procedures. A study was carried out by the Committee on Minimally Invasive and Robotic Surgery of the Brazilian College of Surgeons based on a reviewing strategy of the scientific literature. The study serves as a reference for the creation of a standard for the qualification and certification in robotic surgery according to a statement of the Brazilian Medical Association (AMB) announced on December 17, 2019. The standard proposes a minimum curriculum, integrating training and performance evaluation. The initial (pre-clinical) stage aims at knowledge and adaptation to a specific robotic platform and the development of psychomotor skills based on surgical simulation. Afterwards, the surgeon must accompany in person at least five surgeries in the specialty, participate as a bedside assistant in at least 10 cases and perform 10 surgeries under the supervision of a preceptor surgeon. The surgeon who completes all the steps will be considered qualified in robotic surgery in his specialty. The final certification must be issued by the specialty societies affiliated to AMB. The authors conclude that the creation of a norm for habilitation in robotic surgery should encourage Brazilian hospitals to apply objective qualification criteria for this type of procedure to qualify assistance.

PURPOSE: The benefits of laparoscopic approaches to treat colorectal cancer (CRC) and colorectal liver metastases (CRLM) separately are well established. However, there is no consensus about the optimal timing to approach the primary tumor and CRLM, whether simultaneously or staged. The objective of this review with practical reports is to discuss technical aspects required for patient selection to perform simultaneous laparoscopic approaches for CRC and CRLM. METHODS: Literature review of oncological factors associated with patient selection for surgical treatment of CRLM and the use of laparoscopy in those cases, and report of technical aspects for simultaneous CRC and CRLM approaches. RESULTS: Simultaneous laparoscopic resection has been successful in many series of selected patients, although it seems to be safer to perform minor and major liver resection with non-extended colorectal resections, and to avoid two high-risk procedures at the same time. CONCLUSIONS: Simultaneous CRC and CRLM resections seem to be safe when patients are carefully selected, also considering the risk of recurrence concerning oncologic outcomes. The pre-planning of simultaneous resection is mandatory to plan trocar positioning, procedure sequencing, and patient position.
