Project description:BackgroundThe aim of the present study is to determine the incidence/progression of hiatal hernia (HH) after robotic-assisted coronary artery bypass grafting (RA-CABG) surgery.MethodsWe reviewed the pre- and post-operative computed tomography (CT) of 491 patients who underwent RA-CABG between 2000 and 2017. Post-operative CT was acquired prospectively in a research protocol. CT was reviewed to assess the presence and the size of HH.ResultsWe found 444/491 (90.4%) had pre-operative CT, while 201/491 (40.9%) had post-operative CT. In total, 155/491 (31.6%) had both pre- and long-term post-operative CT with a mean follow-up of 6.2 (±3.5) years. HH was more prevalent on post-operative CT, 64/155 (41.3%) compared to pre-operative CT, 44/155 (28.4%), P<0.0001. The diameter of pre-existing HH 2.8 (±1.8) cm was significantly greater after surgery 3.9 (±2.5) cm, P<0.0001. As well the volume of the pre-existing HH 5.8 (4.4-9.2) mL (quartile) was significantly greater after surgery 14.1 (7.2-64.9) mL, P<0.0001. 20/155 (12.9%) had a newly developed HH after RA-CABG. A binary multivariate regression including HH risk factors showed that male gender is a predictor of developing a HH after RA-CABG with Hazard Ratio of 3.038, confidence interval (1.10-8.43), P=0.033.ConclusionsRA-CABG is associated with an increased risk of developing HH and increases the size of pre-existing HH.

Project description:IntroductionNowadays, minimally invasive surgery in kidney transplantation is a reality thanks to robotic assistance. In this paper, we describe our experience, how we developed the robotic assisted Kidney transplantation (RAKT) technique, and analyze our results. Material and Methods. This is a retrospective study of all RAKTs performed at our center between July 2015 and March 2020. We describe the donor selection, surgical technique, and analyze the surgical results and complications. A comparison between the first 20 cases and the following ones is performed.ResultsDuring the aforementioned period, 82 living donor RAKTs were performed. The mean age was 47.4 ± 13.4 and 50 (61%) were male. Mean body mass index was 25 ± 4.7 and preemptive in 63.7% of cases. Right kidneys and multiple arteries were seen in 14.6% and 12.2%, respectively. Mean operative and rewarming time was 197 ± 42 and 47 ± 9.6 minutes, respectively. Five cases required conversion to open surgery because of abnormal kidney vascularization. Two patients required embolization for subcapsular and hypogastric artery bleeding without repercussion. Three kidneys were lost, two of them due to acute rejection and one because venous thrombosis. Late complications requiring surgery included one kidney artery stenosis, one ureteral stenosis, two lymphoceles, and three hernia repairs. We noticed a significant reduction in time between the first 20 cases and the following ones from 248.25 ± 38.1 to 189.75 ± 25.3 (p < 0.05). With a mean follow-up time of 1.8 years (SD 1.3), the mean creatinine was 1.52 (SD 0.7) and RAKT graft survival was 98%.ConclusionsThe robotic approach is an attractive, minimally invasive method for kidney transplantation, yielding good results. Further studies are needed to consider it a standard approach.

Project description:BACKGROUND:Advancements in surgical robotic technology over the last two decades have enabled coronary artery bypass grafting to be performed totally endoscopically, and have the potential to significantly change clinical practice in the future. METHODS:A systematic review of studies reporting clinical outcomes of total endoscopic coronary artery bypass grafting (TECABG) was performed. RESULTS:14 appraised studies included 880 beating heart TECABGs, 360 arrested heart TECABGs, 633 one-vessel operations and 357 two-vessel operations. Patients were generally low-risk. There was a significant learning curve. The weighted means for short-term beating heart and arrested heart TECABG results respectively were: intraoperative exclusion rate of 5.7% and 1.9%, intraoperative conversion rate of 5.6% and 15.0%, all-cause mortality of 1.2% and 0.4%, stroke of 0.7% and 0.8%, myocardial infarction of 0.8% and 1.8%, new onset atrial fibrillation of 10.7% and 5.1% and post-operative reintervention rate of 2.6% and 2.3%. The overall rate of short term postoperative graft patency for beating heart and arrested heart TECABG was 98.3% and 96.4% respectively. CONCLUSIONS:Appropriate patient selection was important in minimizing the risk of intraoperative and postoperative complications. Short-term outcomes of both beating and arrested heart TECABG were acceptable, but results so far have been heterogeneous. There were fewer studies reporting intermediate to long-term outcomes, but results were encouraging, and further investigation and development of the procedure is warranted.

Project description:Robotic technology is positioned to transform the approach to tracheobronchial surgery. With its magnified 3D view, intuitive controls, wristed-instruments, high-fidelity simulation platforms, and the steady implementation of new technical improvement, the robot is well-suited to manage the careful dissection and delicate handling of the airway in tracheobronchial surgery. This innovative technology has the potential to promote the widespread adoption of minimally invasive techniques for this complex thoracic surgery.

Project description:BackgroundCoronary artery bypass grafting (CABG) has significantly reduced the morbidity and mortality of patients suffering from ischemic heart disease over its six decades of practice. In recent years, minimally invasive techniques have been increasingly described and utilized, with the promise of providing patients with the same standard of care without the need for the traditional full sternotomy, and in select cases without cardiopulmonary bypass, and thus providing improved recovery metrics. The present systematic review and meta-analysis sought to determine the outcomes of all patients receiving robotic-assisted CABG in an Atlantic patient demographic.MethodsThe methods for this systematic review and meta-analysis adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Four databases were searched, using appropriate search terminology. Meta-analysis using proportions or means, as appropriate, were applied, and were presented as per routine practice. Kaplan-Meier curves were digitized and aggregated using previously reported, validated techniques. Quality assessment and risk of bias of each study were assessed systematically. Patient populations were subcategorized as per established technical definitions.ResultsThirty-five studies were identified through the literature search, with three studies having subgroupings appropriate for separate analysis (yielding 42 data points maximally). A total of 9,078 patients (69% male), with a mean age of 62.3 years, were identified across the study period. On actuarial assessment, survival at yearly assessment from 1-, 2-, 3-, 4- and 5-yearly intervals was determined to be 95%, 94%, 92%, 90%, and 88%, respectively.ConclusionsThe present systematic review and meta-analysis demonstrated that short-term mortality, operative time, and admission [intensive care unit (ICU) and overall length of stay] outcomes were encouraging in the Atlantic demographic. Freedom from long-term mortality assessment of a smaller cohort showed encouraging results. A major caveat to the present analysis is the high degree of heterogeneity in the reporting of data. Analysis of future randomized controlled trials will be vital in establishing these procedures as commonplace.

Project description:(1) Background: Although transcatheter technology is rapidly growing and represents a promising strategy, the surgical approach remains the best way to repair a degenerative mitral valve regurgitation. In this context, robotic surgery is technologically the most advanced method of minimally invasive mitral valve repair. The aim of this study is to present the preliminary results of the initial single-center experience with a new robotic mitral valve repair program. (2) Methods: We retrospectively reviewed the records of patients who underwent robotic mitral valve repair at our Institution between January and September 2021. (3) Results: A total of 29 patients underwent mitral valve repair with annuloplasty and chordal implantation to treat degenerative mitral regurgitation. The procedure's success was achieved in 97% of patients. The 30-day cardiac-related mortality was 0%. The median CPB and cross-clamp times were 189 and 111 min, respectively, with a progressive reduction from the beginning of the robotic program. (4) Conclusions: Considering all the limitations related to the small sample, the presented results of robotic mitral valve repair appear to be encouraging and acceptable. A careful patient selection, a dedicated team, and a robust experience in surgical mitral valve repair are the fundamentals to start a new robotic mitral surgery program.

Project description:BackgroundThere is limited data to inform minimum case requirements for training in robotically assisted coronary artery bypass grafting (RA-CABG). Current recommendations rely on nonclinical endpoints and expert opinion.ObjectivesTo determine the minimum number of RA-CABG procedures required to achieve stable clinical outcomes.MethodsWe included isolated RA-CABG in the Society of Thoracic Surgeons (STS) registry performed between 2014 and 2019 by surgeons without prior RA-CABG experience. Outcomes were approach conversion, reoperation, major morbidity or mortality, and procedural success. Case sequence number was used as a continuous variable in logistic regression with restricted cubic splines with fixed effects. Outcomes were compared between operations performed earlier versus later in case sequences using unadjusted and adjusted metrics.ResultsThere were 1195 cases performed by 114 surgeons. A visual inflection point occurs by a surgeon's 10th procedure for approach conversion, major morbidity or mortality, and overall procedural success after which outcomes stabilize. There was a significant decrease in the rate of approach conversion (7.7% and 2.5%), reoperation (18.9% and 10.8%), and major morbidity or mortality (21.7% and 12.9%), as well as an increase in the rate of procedural success (72.9% and 85.3%) with increasing experience between groups. In a multivariable logistic regression model, case sequences of >10 were an independent predictor of decreased approach conversion (odds ratio [OR]: 0.27; 95% confidence interval [CI]: 0.09-0.84) and increased rate procedural success (OR: 1.96; 95% CI: 1.00-3.84).ConclusionsThe learning curve for RA-CABG is initially steep, but stable clinical outcomes are achieved after the 10th procedure.
