Standardization and ten essential steps in the lateral robotic extended totally extraperitoneal (eTEP) repair of ventral hernias / Hérnias ventrais por acesso lateral totalmente extraperitoneal robótico (eTEP): dez etapas essenciais na padronização técnica

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.

A census of laparoscopic and robotic urological practice: a survey of minimally invasive surgery department of the Brazilian Society of Urology

ABSTRACT Minimally invasive urologic surgery has been developing in Brazil and now is a routine part of care in many regions and patients with different conditions benefit from it. Training in laparoscopic and robotic surgery has evolved and concerns exist both over the quality of surgical training and the practical effect on results of the urological training. This is an unprecedented study which undertook a census to determinate the current state of laparoscopic and robotic urological practice and to know the mains barriers to adequate practice in Brazil. In august 2017, surveys, consisting of an anonymous questionnaire with 15 questions, were sent via internet to the mailing list of the Brazilian Society of Urology (SBU). With these data, activities related to laparoscopy and robotic surgery of our urologists and the mains difficulties and barriers to practice laparoscopy and robotic surgery were evaluated. In our survey, 413 questionnaires were completed. Majority of the responders were currently working in the southeast region of Brazil (52.1%) and 75.5% of the surgeons performed laparoscopic surgery while, only 12.8%, robotic surgery. The lack of experience on the technique and the lack of equipment were the mains barriers and difficulties for not executing laparoscopic and robotic surgeries, respectively. Proper longitudinal training and access to good equipment in minimally invasive surgery are still barriers for urologists in our country.

Methodological description of clinical research data collection through electronic medical records in a center participating in an international multicenter study / Abordagem e descrição metodológica do uso do prontuário eletrônico como forma de coleta de dados em pesquisa clínica em centro participante de estudo internacional e multicêntrico

ABSTRACT Data collection for clinical research can be difficult, and electronic health record systems can facilitate this process. The aim of this study was to describe and evaluate the secondary use of electronic health records in data collection for an observational clinical study. We used Cerner Millennium®, an electronic health record software, following these steps: (1) data crossing between the study's case report forms and the electronic health record; (2) development of a manual collection method for data not recorded in Cerner Millennium®; (3) development of a study interface for automatic data collection in the electronic health records; (4) employee training; (5) data quality assessment; and (6) filling out the electronic case report form at the end of the study. Three case report forms were consolidated into the electronic case report form at the end of the study. Researchers performed daily qualitative and quantitative analyses of the data. Data were collected from 94 patients. In the first case report form, 76.5% of variables were obtained electronically, in the second, 95.5%, and in the third, 100%. The daily quality assessment of the whole process showed complete and correct data, widespread employee compliance and minimal interference in their practice. The secondary use of electronic health records is safe and effective, reduces manual labor, and provides data reliability. Anesthetic care and data collection may be done by the same professional.

A comparison of preliminary oncologic outcome and postoperative complications between patients undergoing either open or robotic radical cystectomy

ABSTRACT Purpose: To compare complications and outcomes in patients undergoing either open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RRC). Materials and Methods: We retrospectively identified patients that underwent ORC or RRC between 2003- 2013. We statistically compared preliminary oncologic outcomes of patients for each surgical modality. Results: 92 (43.2%) and 121 (56.8%) patients underwent ORC and RRC, respectively. While operative time was shorter for ORC patients (403 vs. 508 min; p<0.001), surgical blood loss and transfusion rates were significantly lower in RRC patients (p<0.001 and 0.006). Length of stay was not different between groups (p=0.221). There was no difference in the proportion of lymph node-positive patients between groups. However, RRC patients had a greater number of lymph nodes removed during surgery (18 vs. 11.5; p<0.001). There was no significant difference in the incidence of pre-existing comorbidities or in the Clavien distribution of complications between groups. ORC and RRC patients were followed for a median of 1.38 (0.55-2.7) and 1.40 (0.582.59) years, respectively (p=0.850). During this period, a lower proportion (22.3%) of RRC patients experienced disease recurrence vs. ORC patients (34.8%). However, there was no significant difference in time to recurrence between groups. While ORC was associated with a higher all-cause mortality rate (p=0.049), there was no significant difference in disease-free survival time between groups. Conclusions: ORC and RRC patients experience postoperative complications of similar rates and severity. However, RRC may offer indirect benefits via reduced surgical blood loss and need for transfusion.
