Virtual assessment of coronal balance prior to bone resection with the MAKO robotic-assisted system accurately predicts final balance in TKA
This study aims to assess the accuracy of this pre-resection balancing technique in determining the resultant final soft tissue balance of the TKA. A consecutive prospective cohort of 2027 Robotic-Assisted TKAs (RATKA) were performed between January’17 and March’22. Osteophytes were removed; i nitial virtual gaps on the virtual bone model were measured at 10° and 90° of flexion prior to bone resections. Optimization of the virtual component positions was then made and final pre-resection gaps were measured. The gaps were then re-assessed post-implantation and compared to the final pre-r esection values. Virtual balan...

Robotic retroperitoneal lymph node dissection for paratesticular rhabdomyosarcoma in adolescents: a case series
We present an analysis of RA-RPLND for boys with paratesticular RMS. We queried our ins titution’s prospectively collected database of pediatric robotic cases for patients undergoing RA-RPLND post-radical orchiectomy for paratesticular mass, confirmed by pathology as RMS. Demographic, surgical, follow-up, and oncological outcomes were evaluated between 2017 and 2023. Five patients un derwent RA-RPLND for paratesticular RMS. The median age was 16.1 years (15–17), with median OR time of 456 min (357–508). No conversions to open occurred. Inpatient median total opioid use was 1.8 (0.4–2.7) morphine equivalent/kg. Th...

Safety and feasibility of robotic surgery for colon cancer patients with previous abdominal surgery: a propensity score-matching analysis
This study was aimed to evaluate the safety and feasibility of robotic colectomy for patients with PAS. The medical records of colon cancer patients who underwent robotic surgery at our hospital from June 2015 to August 2020 were extracted and analyzed. Propensity score-matching (PSM) analysis was implemented to minimize selection bias. We compared perioperative outcomes and postoperative complications between the patients with PAS or with no PAS (NPAS). A total of 79 patients (PAS group) and 348 patients (NPAS group) were included in our study. After PSM, 79 patients of PAS group and 79 patients of NPAS group were selecte...

Comparative analysis of short-term outcomes and oncological results between robotic-assisted and laparoscopic surgery for rectal cancer by multiple surgeon implementation: a propensity score-matched analysis
This study aimed to compare the short-term outcomes of robotic surgery, focusing on pathological results and disease-free survival (DFS), in our cohort with initial robotic experience by multiple surgeon implementation. This retrospective study enrolled 571 patients diagnosed with rectal cancer, who were treated with chemoradiotherapy and surgery between January 2015 and December 2021. Surgical outcomes after RAS and laparoscopic surgery (LS) were compared using a propensity score-matching (PSM) analysis. After matching, 200 patients (100 in each group) were included. The median operative time was significantly longer in t...

Learning curve for robotic rectal cancer resection at a community-based teaching institution
This study aims to evaluate the learning curve of robotic rectal cancer resections at a community-based teaching institution and evaluate clinical and oncologic outcomes. A retrospective review of consecutive robotic rectal cancer resections by a single surgeon was performed for a five-year period. The cumulative sum (CUSUM) for total operative time was calculated and plotted to establish a learning curve. The oncologic and post-operative outcomes for each phase were analyzed and compared. The CUSUM learning curve yielded two phases, the learning phase (cases 1 –79) and the proficiency phase (cases 80–130). The median ...

Outcomes of salvage robot-assisted radical prostatectomy in patients who had primary focal versus whole-gland ablation: a multicentric study
We present the largest multi-institutional analyses of f-SRARP and wg-SRARP. SRARP is challenging wherein patients have adverse pathological features and increased surgical complexity irrespective of the primary treatment. Focal therapy group had higher rates of nerve-sparing, however, with increased positive surgical margins. Both groups had poor functional outcomes regardless of nerve-sparing degree, indicating significant ipsilateral and contralateral damag e to tissues surrounding the prostate during primary treatment. We believe that this analysis is crucial for counseling patients regarding expected outcomes before p...

The invasiveness of robot-assisted total hip replacement is similar to that of conventional surgery
AbstractRobot-assisted total hip arthroplasty (R-THA) is increasingly being performed throughout the world. The invasiveness of this operation is unknown. We retrospectively reviewed the cohort of consecutive osteonecrosis of the femoral head (ONFH) patients who received primary R-THA or manual THA (M-THA) from January 2020 to January 2022 in our institution. One experienced surgeon performed all procedures. We calculated the propensity score to match similar patients in different groups by multivariate logistic regression analysis for each patient. We included confounders consisting of age, sex, body mass index (BMI), and...

Surgical skill level classification model development using EEG and eye-gaze data and machine learning algorithms
AbstractThe aim of this study was to develop machine learning classification models using electroencephalogram (EEG) and eye-gaze features to predict the level of surgical expertise in robot-assisted surgery (RAS). EEG and eye-gaze data were recorded from 11 participants who performed cystectomy, hysterectomy, and nephrectomy using the da Vinci robot. Skill level was evaluated by an expert RAS surgeon using the modified Global Evaluative Assessment of Robotic Skills (GEARS) tool, and data from three subtasks were extracted to classify skill levels using three classification models —multinomial logistic regression (MLR), ...

Robotic pyeloplasty learning curve for a pediatric surgeon without previous laparoscopic pyeloplasty experience
AbstractRobotic pyeloplasty has become a technique of choice for pyelo-ureteral junction syndrome treatment in children. Less invasive than open surgery, robotic pyeloplasty also has a lower learning curve than laparoscopic pyeloplasty. This is how a new generation of surgeons without previous laparoscopic pyeloplasty experience has begun training in robotics. To assess the robotic assisted pyeloplasty learning curve for a pediatric surgeon only trained in open pyeloplasty, and to investigate if that mode of practice is safe and effective. Data were collected from all children operated on for pyelo-ureteral junction syndro...

Patient outcomes and cost in robotic emergency general surgery
This study explores the current trends in patient outcomes and cost of robotic emergency general surgery (REGS). The Florida Agency for Healthcare Administration database (2018 –2020) was queried for adult patients undergoing intra-abdominal emergency general surgery within 24 h of admission and linked to CMS Cost Reports/Hospital Compare, American Hospital Association, and Rand Corporation Hospital datasets. Patients from the four most common REGS procedures were prope nsity matched to laparoscopic equivalents for hospital cost analysis.

Comparison of operative and fertility outcomes of single-incision robotic myomectomy: a retrospective single-center analysis of 286 cases
AbstractTo assess the short-term operative and fertility outcomes of single-incision robotic myomectomy. We performed this retrospective cohort study of 286 women who underwent robotic single-site myomectomy using the da Vinci ® Xi surgical system (RSSM group,n = 70) or robotic single-port myomectomy using the da Vinci® SP surgical system (RSPM group,n = 216). Data were collected through chart reviews and telephone interviews. Except operating time (94.6 ± 30.1 min in RSSM vs. 81.7 ± 20.1 min in RSPM) and location of the removed fibroids, there were no significant differences in the operative outcomes...

Feasibility of robotic multivisceral resections in colorectal cancer patients: a NSQIP-based study
AbstractMultivisceral robotic surgery may be an alternative to sequential procedures in select patients with colorectal cancer who are diagnosed with synchronous lesions or in those who require additional procedures at the time of resection. The aim of this study was to assess utilization of the robot for multivisceral resections and compare the surgical outcomes of this approach to laparoscopic resections. Adult colorectal surgery patients who underwent a colectomy or proctectomy and a concurrent abdominal surgery procedure in the American College of Surgeons NSQIP database (2016 –2021) were included. The primary outcom...
