Multicenter Multireader Evaluation of an Artificial Intelligence-Based Attention Mapping System for the Detection of Prostate Cancer With Multiparame…

2020

OBJECTIVE. The purpose of this study was to evaluate in a multicenter dataset the performance of an artificial intelligence (AI) detection system with attention mapping compared with multiparametric MRI (mpMRI) interpretation in the detection of prostate cancer. MATERIALS AND METHODS. MRI examinations from five institutions were included in this study and were evaluated by nine readers. In the first round, readers evaluated mpMRI studies using the Prostate Imaging Reporting and Data System version 2. After 4 weeks, images were again presented to readers along with the AI-based detection system output. Readers accepted or rejected lesions within four AI-generated attention map boxes. Additio…

Head-Mounted Mixed-Reality Technology During Robotic-Assisted Transanal Total Mesorectal Excision

2019

INTRODUCTION Head-mounted mixed-reality technologies may enable advanced intraoperative visualization during visceral surgery. In this technical note, we describe an innovative use of real-time mixed reality during robotic-assisted transanal total mesorectal excision. TECHNIQUE Video signals from the robotic console and video endoscopic transanal approach were displayed on a virtual monitor using a head-up display. The surgeon, assistant, and a surgical trainee used this technique during abdominal and transanal robotic-assisted total mesorectal excision. We evaluated the feasibility and usability of this approach with the use of validated scales. RESULTS The technical feasibility of the rea…

Does conversion during minimally invasive rectal surgery for cancer have an impact on short-term and oncologic outcomes? Results of a retrospective c…

2021

International audience; Background: Although minimally invasive rectal surgery (MIRS) for cancer provides better recovery for similar oncologic outcomes over open approach, conversion is still required in 10% and its impact on short-term and long-term outcomes remains unclear. The aim of our study was to evaluate the impact of conversion on postoperative and oncologic outcomes in patients undergoing MIRS for cancer. Methods: From June 2011 to March 2020, we reviewed 257 minimally invasive rectal resections for cancer recorded in a prospectively maintained database, with 192 robotic and 65 laparoscopic approaches. Patients who required conversion to open (Conversion group) were compared to t…

Robot-assisted minimally invasive esophagectomy (RAMIE) compared to conventional minimally invasive esophagectomy (MIE) for esophageal cancer: a prop…

2020

SUMMARY Robot-assisted minimally invasive esophagectomy (RAMIE) is increasingly being applied as treatment for esophageal cancer. In this study, the results of 50 RAMIE procedures were compared with 50 conventional minimally invasive esophagectomy (MIE) operations, which had been the standard treatment for esophageal cancer prior to the robotic era. Between April 2016 and March 2018, data of 100 consecutive patients with esophageal carcinoma undergoing modified Ivor Lewis esophagectomy were prospectively collected. All operations were performed by the same surgeon using an identical intrathoracic anastomotic reconstruction technique with the same perioperative management and pain control re…

Robotic-assisted pancreaticoduodenectomy with vascular resection. Description of the surgical technique and analysis of early outcomes

2019

Abstract Background Despite the potential benefits, the adoption of the minimally invasive surgery for the treatment of borderline resectable pancreatic cancer is still in the initial phase. We investigated the safety and feasibility of the robotic pancreaticoduodenectomy with venous resection/reconstruction (RPD SMV/PV). Methods Since March 2013 to October 2019, a total of 73 RPD and 10 RPD SMV/PV were performed. The two groups were case-matched according to the preoperative characteristics. Results Mean operative times and estimated blood loss were less in the RPD group in comparison to that in the RPD with SMV-PV group (525 vs 642 min, p = 0.003 and 290 vs 620 ml, p = 0.002, respectively…

Robotic assisted prostatic surgery in the Trendelenburg position does not impair cerebral oxygenation measured using two different monitors: A clinic…

2014

Robotic assisted prostatic surgery is frequently used because of its reduced side-effects compared with conventional surgery. During surgery, an extreme Trendelenburg position and CO2 pneumoperitoneum are necessary, which may lead to cerebral oedema, can potentially reduce brain perfusion and therefore could impair cerebral oxygenation. Cerebral oxygen saturation can be measured non-invasively using near-infrared spectroscopy (NIRS).The hypothesis of the present study was that steep Trendelenburg positioning during robotic assisted prostatic surgery impairs cerebral oxygen saturation measured using two different NIRS monitors.Clinical observational study.Primary care university hospital, st…

Predicting trajectories of recovery in prostate cancer patients undergone Robot-Assisted Radical Prostatectomy (RARP)

2019

ObjectiveTo identify trends of patients' urinary and sexual dysfunctions from a clinical and psychological perspective and understand whether sociodemographic and medical predictors could differentiate among patients following different one-year longitudinal trajectories.MethodsAn Italian sample of 478 prostate cancer patients undergone Robot-Assisted Radical Prostatectomy completed the EPIC-26 survey between July 2015 and July 2016 at the pre-hospitalization (T0), 45 days (T1) and 3 (T2), 6 (T3), 9 (T4), and 12 months (T5) after surgery. Sociodemographic and clinical characteristics (age, BMI, diabetes, nerve-sparing procedure) were also collected. Latent Class Growth Analysis was conducte…

Full in vitro fertilization laboratory mechanization: toward robotic assisted reproduction?

2011

Objective To describe the current efforts made to standardize different steps of assisted reproductive technology processes by the introduction of new technologies for the nonsubjective sperm selection process, oocyte denudation by mechanical removal of cumulus cells, oocyte positioning, sperm motility screening, fertilization, embryo culture, media replacement by microfluidics, and monitoring of embryo development by time-lapse photography, embryo secretions, and/or O 2 consumption. These technologies could be integrated in a unique and fully automated device. Design Pubmed database and research and development data from authors. Setting University-affiliated private center.

Robotic surgery can be safely performed for patients and healthcare workers during COVID‐19 pandemic

2021

OBJECTIVES: To investigate the safety of robotic surgery during COVID-19 pandemic concerning new-acquired COVID-19 infections for patients and healthcare workers. PATIENTS: We performed a retrospective single-centre cohort study of patients undergoing robotic surgery in initial period of COVID-19 pandemic. Patients and Healthcare workers COVID-19 infection status was assessed by structured telephone follow-up and/or repeated nasopharyngeal swabs. RESULTS: After 61 robotic surgeries (93,5% cancer surgery), 1 patient (1.6%) had COVID-19 infection. 60 healthcare workers cumulatively exposed to 1,187 hours of robotic surgery had no infection. One patient with postoperative proof of SARS-CoV-2 h…
