Objective: The analysis of surgical videos using artificial intelligence holds great promise for the future of surgery by facilitating the development of surgical best practices, identifying key pitfalls, enhancing situational awareness, and disseminating that information via real‐time, intraoperative decision‐making. The objective of the present study was to examine the feasibility and accuracy of a novel computer vision algorithm for hysterectomy surgical step identification. Methods: This was a retrospective study conducted on surgical videos of laparoscopic hysterectomies performed in 277 patients in five medical centers. We used a surgical intelligence platform (Theator Inc.) that employs advanced computer vision and AI technology to automatically capture video data during surgery, deidentify, and upload procedures to a secure cloud infrastructure. Videos were manually annotated with sequential steps of surgery by a team of annotation specialists. Subsequently, a computer vision system was trained to perform automated step detection in hysterectomy. Analyzing automated video annotations in comparison to manual human annotations was used to determine accuracy. Results: The mean duration of the videos was 103 ± 43 min. Accuracy between AI‐based predictions and manual human annotations was 93.1% on average. Accuracy was highest for the dissection and mobilization step (96.9%) and lowest for the adhesiolysis step (70.3%). Conclusion: The results of the present study demonstrate that a novel AI‐based model achieves high accuracy for automated steps identification in hysterectomy. This lays the foundations for the next phase of AI, focused on real‐time clinical decision support and prediction of outcome measures, to optimize surgeon workflow and elevate patient care. Synopsis: AI‐based model achieves high‐accuracy surgical step detection in laparoscopic hysterectomies, paving the way for incorporation of surgical intelligence platforms in gynecology.

Background/Objectives: This study evaluates the safety and surgical outcomes of performing robotic hysterectomy on uteri weighing over 1000 g, with a focus on the surgeon's learning curve. Methods: A retrospective analysis was conducted on 44 patients who underwent hysterectomy by a single surgeon from January 2020 to February 2024 using the DaVinci Xi System. Surgical procedures included total hysterectomy with bilateral salpingectomy, and specimens were removed via transvaginal manual morcellation. Operative times were segmented into docking, console, morcellation, and conversion times. Results: Results indicated an inflection point in the 20th case, suggesting proficiency after 20 surgeries. Comparison between early (Group A, cases 1–20) and later cases (Group B, cases 21–44) showed significant reductions in console time (CT) and morcellation time (MT) in Group B, leading to a shorter overall operative time (OT). Although estimated blood loss was higher in Group A, it was not statistically significant. Hemoglobin differences were significantly higher in Group B. No significant differences were observed in transfusion rates, postoperative analgesic usage, or complications between the groups. Conclusions: The study concludes that robotic hysterectomy for large uteri is safe and that surgical proficiency improves significantly after 20 cases, enhancing overall outcomes.

Introduction: The da Vinci SP surgical system is a surgical platform capable of implementing robotic‐assisted surgery through a single port and was first introduced in Japan at our hospital. In this paper, we describe our experience of the initial introduction of the da Vinci SP surgical system and its surgical outcomes. This is the first report on the surgical outcomes of using da Vinci SP, and its comparison with the conventional system in Japan. Methods: After developing an application for a highly difficult new medical technology in‐house, we compared the surgical outcomes (median values) of 15 patients who had undergone total hysterectomy at our hospital using the da Vinci SP (1‐port) system (SP group) for uterine myoma after March 2023 and of 154 patients who underwent total hysterectomy using the conventional da Vinci Xi (four ports) system (Xi group) for uteri weighing <500 g. Results: The results of the comparison of the characteristics between 15 patients in the SP group and 154 patients in the Xi group were as follows: uterus weight (g): 230 (90–500) versus 222 (55–496) (p =.35); surgical time (minutes): 199 (171–251) versus 198 (88–387) (p =.63); intraoperative blood loss (mL): 13 (5–82) versus 20 (2–384) (p =.17); and rate of surgical complication (%): 0.0 versus 1.3 (p =.66). The data indicated a comparable weight of the resected uterus, surgical time, intraoperative blood loss, and rate of surgical complications between the two groups. Conclusion: Robotic‐assisted total hysterectomy using the da Vinci SP surgical system allowed clinicians to safely perform surgeries according to the conventional systems. [ABSTRACT FROM AUTHOR]

Objective: In robot-assisted minimally invasive surgery, proper port positioning ensures that surgical tools have adequate access to the surgical site and avoids mid-surgery collisions of robotic arms. To date, several guidelines have been proposed for more accurate port placement. However, challenges remain due to variations in patient morphology, anatomy, and, in particular, organ displacement due to insufflation in certain laparoscopic procedures. The objective of this study was to design and develop a decision aid for optimal port placement in robot-assisted hysterectomy that accounts for patient variability and organ displacement due to insufflation. Methods: Three components were constructed: a robot model, a patient-specific model, and an optimization algorithm. The three components were integrated, and the system was verified using four different patients who underwent robotic hysterectomy. Once verified, two expert surgeons were asked to evaluate the decision aid for face and construct validity. A usability test was conducted using a torso phantom with target organs located in three different locations. Two expert surgeons performed a simulated hysterectomy task with and without the decision aid to evaluate performance and satisfaction. Results: The optimization algorithm was sensitive to individual differences in anatomy in the four patients. Expert surgeons successfully established face and construct validity. Usability test results showed a 28%–40% reduction in time to task completion with the optimized ports compared to expert-determined port locations without using the decision aid. Conclusions: The decision aid, based on an individualized patient-specific model, robot model, and optimization algorithm, was shown to be effective at addressing the challenges of displaced organs due to insufflation in robot-assisted hysterectomy. The face and construct validity of the decision aid was established by expert surgeons, while efficiency gains in task performance were demonstrated experimentally.

Introduction and hypothesis: The objective was to study the effect of immediate pre-operative warm-up using virtual reality simulation on intraoperative robot-assisted laparoscopic hysterectomy (RALH) performance by gynecology trainees (residents and fellows). Methods: We randomized the first, non-emergent RALH of the day that involved trainees warming up or not warming up. For cases assigned to warm-up, trainees performed a set of exercises on the da Vinci Skills Simulator immediately before the procedure. The supervising attending surgeon, who was not informed whether or not the trainee was assigned to warm-up, assessed the trainee's performance using the Objective Structured Assessment for Technical Skill (OSATS) and the Global Evaluative Assessment of Robotic Skills (GEARS) immediately after each surgery. Results: We randomized 66 cases and analyzed 58 cases (30 warm-up, 28 no warm-up), which involved 21 trainees. Attending surgeons rated trainees similarly irrespective of warm-up randomization with mean (SD) OSATS composite scores of 22.6 (4.3; warm-up) vs 21.8 (3.4; no warm-up) and mean GEARS composite scores of 19.2 (3.8; warm-up) vs 18.8 (3.1; no warm-up). The difference in composite scores between warm-up and no warm-up was 0.34 (95% CI: −1.44, 2.13), and 0.34 (95% CI: −1.22, 1.90) for OSATS and GEARS respectively. Also, we did not observe any significant differences in each of the component/subscale scores within OSATS and GEARS between cases assigned to warm-up and no warm-up. Conclusion: Performing a brief virtual reality-based warm-up before RALH did not significantly improve the intraoperative performance of the trainees. [ABSTRACT FROM AUTHOR]

Malignant peritoneal cytology in endometrial cancer (EC) is not considered an independent adverse prognostic factor for uterine-confined disease and is not a determinant factor in the International Federation of Gynecology and Obstetrics (FIGO) staging system. NCCN Guidelines still recommend obtaining cytologies. The aim of this study was to determine the prevalence of peritoneal cytologic contamination following robotic hysterectomy for EC. Peritoneal cytology from the pelvis and diaphragm were obtained at the initiation of surgery, and from the pelvis only at the completion of robotic hysterectomy with sentinel lymph node mapping (SLNM). Cytology specimens were evaluated for the presence of malignant cells. Pre- and post-hysterectomy cytology results were compared, and pelvic contamination was defined as conversion from negative to positive cytology following surgery. 244 patients underwent robotic hysterectomy with SLNM for EC. Pelvic contamination was identified in 32 (13.1%) cases. In multivariate analysis, pelvic contamination was associated with >50% myometrial invasion, tumor size >2 cm, lymphovascular space invasion (LVSI), and lymph node metastasis. There was no association with FIGO stage or histology subtypes. Malignant peritoneal contamination occurred during robotic surgery for EC. Large lesions (>2 cm), deep invasion (>50%), LVSI, and lymph node metastasis were each independently associated with peritoneal contamination. Whether or not peritoneal contamination increases risk for disease recurrence should be studied in larger series, including an evaluation of patterns of recurrence and the potential impact of adjuvant therapies. Until the clinical impact of peritoneal contamination during hysterectomy for EC is better understood, methods to reduce peritoneal contamination are warranted. • The role of peritoneal cytology during staging for endometrial cancer remains debated. • Pelvic contamination is encountered during robotic hysterectomy for endometrial cancer. • Malignant pelvic contamination is associated with high-risk uterine factors. • Methods to decrease rates of pelvic contamination during robotic hysterectomy for endometrial cancer are warranted.

This study aimed to review the surgical outcomes of supracervical hysterectomy using the da Vinci SP® surgical system and conventional single-site laparoscopic surgery for uterine fibroids. This study included 79 patients who underwent supracervical hysterectomy with the da Vinci SP® surgical system and conventional single-site laparoscopy for uterine fibroid between June 2018 and April 2021. All the surgeries were performed by an experienced surgeon. Surgical outcomes and complications were reviewed in both groups. No significant difference was found between the two groups with regards to the patients' preoperative surgical conditions such as weight of the uterus, history of pelvic surgery, and pelvic adhesion. A significantly longer operation time (p < 0.01) and higher levels of C-reactive protein (p < 0.01) were found in the robotic surgery group; in particular, the uterus-out time was significantly longer (p < 0.01). No significant differences were found in other surgical outcomes such as complication rates and hospital stays. Supracervical hysterectomy using the da Vinci® SP surgical system is comparable to conventional single-site laparoscopy in uncomplicated cases. However, it requires a significantly longer operative time and has a higher inflammatory response. [ABSTRACT FROM AUTHOR]

Vaginal cuff dehiscence (VCD) is a rare but serious condition associated with high morbidity, especially in the presence of an evisceration. It usually occurs as a complication of hysterectomy, but has also been reported after other pelvic surgeries. In this article, we will present two cases of vaginal cuff dehiscence with evisceration in post-menopausal patients. Both cases occurred post-operatively, the first after a laparoscopic radical hysterectomy and the other after a trachelectomy performed by robotic-assisted laparoscopy (with a prior history of subtotal hysterectomy). Both cases were treated surgically, the first by a combined laparoscopic and vaginal approach, and the second case only by laparoscopic approach. The main risk and protective factors are discussed in a narrative literature review which summarizes the available evidence on this rare condition, discussed by type of study designs and thus evidence level. A laparoscopic vaginal cuff closure is the most protective factor in preventing VCD, compared to a vaginal closure. Clinicians should be aware of this condition and of its risk factors and precipitating events in order to identify high-risk patients. Knowledge of these allows prompt recognition, which is crucial for adequate management, for which multiple approaches have been described. [ABSTRACT FROM AUTHOR]

To analyze hysterectomy trends and vaginal cuff dehiscence (VCD) rates by mode of surgery at a tertiary care medical center and to describe characteristics of VCD cases. Observational retrospective cohort study. Large academic hospital and affiliated community hospital. 4722 patients who underwent hysterectomy at Columbia University Irving Medical Center between January 2010 and August 2021. Current Procedural Terminology and International Classification of Diseases codes identified hysterectomies and VCD cases. Hysterectomy trends and VCD rates were calculated by mode of surgery. Relative risks of VCD for each mode were compared with total abdominal hysterectomy (TAH). Clinical characteristics of VCDs were reviewed. There were 4059 total hysterectomies. Laparoscopic hysterectomies, including total laparoscopic hysterectomies (TLHs), laparoscopic-assisted vaginal hysterectomies, and robot-assisted TLHs (RA-TLHs), increased from 41.9% in 2010 to 65.9% in 2021 (p <.001). RA-TLH increased from 5.7% in 2010 to 40.2% in 2021. Supracervical hysterectomies followed similar trends and were excluded from VCD analysis. There were 15 VCDs (overall rate 0.37%). VCD was highest after RA-TLH (0.66%), followed by TLH (0.32%) and TAH (0.27%), with no VCDs after laparoscopic-assisted vaginal hysterectomy or total vaginal hysterectomy. Compared with TAH, the relative risk for VCD after RA-TLH was 2.44 (95% confidence interval 0.66–9.00) and after TLH was 1.18 (95% confidence interval 0.24–5.83), which were not statistically significant. The mean time to dehiscence was 39 days (range 8–145 days). The most common trigger event was coitus (41%). VCD rates were low (<1%) for all modes of hysterectomy, and rates after robotic and laparoscopic hysterectomy were much lower than previously reported. Although VCD rates trended higher after robotic and laparoscopic hysterectomy compared with abdominal hysterectomy, the difference was not significant. It is difficult to determine whether this finding represents true lack of difference vs a lack of power to detect a significant difference given the rarity of VCD. [ABSTRACT FROM AUTHOR]

The use and application of robotic systems with a high-definition, three-dimensional vision system and advanced EndoWrist technology have become widespread. We sought to share our clinical experience with ureter identification and preventive uterine artery ligation in robotic hysterectomy. The records of patients undergoing robotic hysterectomy between May 2014 and December 2015, including patient preoperative characteristics, operative time, and postoperative outcomes, were analyzed. We evaluated the feasibility and safety of using early ureteral identification and preventive uterine artery ligation in robotic hysterectomy in patients with benign gynecological conditions. Overall, 49 patients diagnosed with benign gynecological conditions were evaluated. The mean age of the patients and mean uterine weight were 46.2 ± 5.3 years and 348.7 ± 311.8 g, respectively. Robotic hysterectomy achieved satisfactory results, including a short postoperative hospital stay (2.7 ± 0.8 days), low conversion rate (n = 0), and low complication rate (n = 1; 2%). The average estimated blood loss was 109 ± 107.2 mL. Our results suggest that robotic hysterectomy using early ureteral identification and preventive uterine artery ligation is feasible and safe in patients with benign gynecological conditions.

Objective: The aim of this study was to describe, from a historical perspective, the relevance, resilience and outcomes of vaginal hysterectomy (VH) in gynecology in the age of technological scenario. Methods: The authors searched records from January 2011 to January 2021 on the following databases: Medline, EMBASE, and CENTRAL (The Cochrane Library) for combinations of the terms "vaginal hysterectomy," "outcomes" AND "history"; and before that period, if the search had historical relevance. Inclusion criteria: randomized clinical trials; hysterectomy performed for benign gynecological conditions; and VH outcomes compared with Abdominal Hysterectomy (AH), Laparoscopic Hysterectomy (LH) or Robotic Hysterectomy (RH). Results: The VH combines sequences of reproducible techniques which have been developed over the years to safely and effectively overcome the limitations of difficult cases of vaginal extirpation from the uterus. Conclusion: The authors support endoscopic surgical approaches in complex surgery for benign indications, urogynecology, and gynecologic oncology when appropriate. However, what makes the gynecological surgeon different from the general surgeon is the vaginal access. It is essential to continue to train residents in vaginal surgical skills and provide safe and cost-effective patient care. The art of technology is the resilience of keeping only the patient at the center of innovation. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the factors in feasibility and safety of same-day dismissal (SDD) of endometrial cancer patients undergoing robotic hysterectomy and staging. A single-institution retrospective chart review of endometrial cancer patients who underwent robotic hysterectomy and staging between 2012 and 2021 was performed. Patient demographics, medical and surgical history, intra- and postoperative events were examined as possible factors related to non-SDD. These factors were analyzed using univariate (chi-square test) and multivariate logistic regression analysis. Of the 292 patients, 117 (40%) had SDD, and 175 (60%) had non-SDD. The SDD rate increased from 13.8% to 88% over the 10-year study period. The factors significantly associated with non-SDD (p < 0.05) were surgery in the first 5 years after the introduction of the SDD and ERAS protocols (2012–2016), age > 75 years, and comorbidities such as cardiovascular diseases, anemia (Hb < 11 g/dl), and anticoagulant therapy. Extensive adhesiolysis, the performance of complete pelvic and/or aortic lymphadenectomy, operating time > 180 min, and PACU discharge after 2:00 p.m. were significant factors for non-SDD. Sentinel lymph node sampling was significantly associated with SDD (OR 0.050; CI 0.273–0.934, p = 0.029). We reported no significant difference in the number, setting and timing of any unscheduled postoperative contacts, complications, and readmissions between SDD and non-SDD groups. SDD after robotic hysterectomy and staging for endometrial cancer is feasible and safe. There are patient and surgery factors for the failure of SDD. The sentinel lymph node sampling was significantly associated with achieving SDD. Trial registration: Institutional Review Board approved the study protocol (#: 1764–05). [ABSTRACT FROM AUTHOR]

Hysterectomy is commonly performed for benign gynecological diseases. Minimally invasive surgical approaches offer several advantages. Unfortunately, few studies have compared the outcomes of different types of minimally invasive surgeries. Therefore, this study aimed to compare the surgical outcomes of robotic hysterectomy (RH) and conventional laparoscopic hysterectomy (CLH) in benign gynecologic diseases. We performed a retrospective cohort study at a single center between January 2014 and July 2022. A total of 397 patients (RH: 197 and CLH: 200) who underwent minimally invasive hysterectomy for benign diseases with uterine size exceeding 250 g were enrolled, and factors related to the surgical outcomes were compared. The median age was 46 (range, 35–74) years, and the median uterine weight was 400 (range, 250–2720) g. There were no significant differences between the two groups regarding age, body mass index, uterine weight, hospital stay, estimated blood loss, or operating time. Intraoperative and postoperative complication rates were not significantly different between the two groups. RH was not inferior to CLH in terms of perioperative and immediate postoperative outcomes in our study. [ABSTRACT FROM AUTHOR]

Introduction The purpose of this report is to describe a technique for performing a robotic total laparoscopic hysterectomy (rTLH) with clinical outcomes on safety and efficiency. The rationale for our approach is based on a critical evaluation of the literature. Methods Data from all rTLH procedures performed on our gynecologic oncology service between January 2017 and December 2019 were retrospectively reviewed. Using this database, perioperative data including surgical times, intra- and postoperative complications, and length of hospital stays were evaluated. The steps used to perform the procedure were outlined and illustrated. Results 826 cases of rTLH were performed during the study period. 688 of these cases were included for analysis. Malignant diagnoses were found in 218 cases. The median time from skin-to-skin for the entire cohort was 28.43 minutes for benign rTLH +/- BSO (bilateral salpingo oophorectomy) and 30.23 minutes for rTLH/BSO/cancer staging. Surgical complications included vaginal laceration, vaginal bleeding, urinary tract infection, serous fluid leakage from the incision, abdominal wall abscess, pelvic abscess, surgical site infection, serosal tear, enterotomy, rectal injury, acute kidney injury, perforated diverticulitis, and incarcerated bowel through the ventral hernia. The median length of stay was 1 day. The surgical technique is illustrated step by step. Conclusion This paper describes a safe and efficient technique to perform rTLH and shows that surgical times, complication rates, and length-of-stays compare favorably to the literature. A description of the technique clarifies many of the details of this procedure which can be made routine to minimize error and surgeon discrepancies. We encourage readers to use this paper as a guide to modify their techniques for robotically assisted laparoscopic hysterectomy.

Introduction: The primary goal is to analyze the learning curve of surgical parameters (docking, operation and console time) between multiport and single-site robotic hysterectomy techniques, performed by expert laparoscopic surgeons. Material and methods: The trial is a retrospective analysis of 229 patients enrolled between 2010 and 2018 who underwent robotic hysterectomies with bilateral salpingo-oophorectomies (HBSO) for gynecological diseases. Results: Surgical parameters, learning curve and surgical outcomes were analyzed in order to evaluate the transition from multiport to single-site programs, performed by non-expert surgeons using the multiport technique. All surgical times (total, docking and console time) were shorter in the multiport robotic hysterectomy group, while the intraoperative complication rate was lower in the robotic single-site hysterectomy group (p = 0.007). The learning curve of operative, console and docking time significantly decreased more in the robotic-single site hysterectomy group, than in the multiport robotic hysterectomy group over time (p value < 0.001). Conclusions: The direct transition from the laparoscopy program to the single-site approach is feasible and effective in HBSO performed by expert laparoscopic surgeons. The learning curve of robotic single-site hysterectomy shows that the proficiency in this technique requires more cases than the multiport robotic hysterectomy cases and needs more time to fit the surgical step to the single-site platform.

Study Objective: To gather validity evidence for and determine acceptability of Surgical Science-Simbionix Hysterectomy Modules for the DaVinci Xi console simulation system (software; 3D Systems by Simbionix [now Surgical Science-Simbionix], Littleton, CO, and hardware; Intuitive Surgical, Inc., Sunnyvale, CA) and evaluate performance benchmarks between novice and experienced or expert surgeons.Design: Prospective education study (Messick validity framework).Setting: Multicenter, academic medical institutions.Participants: Residents, fellows, and faculty in obstetrics and gynecology were invited to participate at 3 institutions. Participants were categorized by experience level: fewer than 10 hysterectomies (novice), 10 to 50 hysterectomies (experienced), and more than 50 hysterectomies (expert). A total of 10 novice, 10 experienced, and 14 expert surgeons were included.Interventions: Participants completed 4 simulator modules (ureter identification, bladder flap development, colpotomy, complete hysterectomy) and a qualitative survey. Simulator recordings were reviewed in duplicate by educators in minimally invasive gynecologic surgery using the Modified Global Evaluative Assessment of Robotic Skills (GEARS) rating scale.Measurements and Main Results: Most participants felt that the simulator realistically simulated robotic hysterectomy (64.7%) and that feedback provided by the simulator was as or more helpful than feedback from previous simulators (88.2%) but less helpful than feedback provided in the operating room (73.5%). Participants felt that this simulator would be helpful for teaching junior residents. Simulator-generated metrics correlated with GEARS performance for the bladder flap and ureter identification modules in multiple domains including total movements and total time for completion. GEARS performance for the bladder flap module correlated with experience level (novice vs experienced/expert) in the domains of interest and total score but did not consistently correlate for the other procedural modules. Performance benchmarks were evaluated for the bladder flap module for each GEARS domain and total score.Conclusion: The modules were well received by participants of all experience levels. Individual simulation modules appear to better discriminate between novice and experienced/expert users than overall simulator performance. Based on these data and participant feedback, the use of individual modules in early residency education may be helpful for providing feedback and may ultimately serve as 1 component of determining readiness to perform robotic hysterectomy.

The laparoscopic hysterectomy readmission score (LHRS) was created to identify patients for whom same day discharge (SDD) after minimally invasive hysterectomy (MIH) may not be advisable and includes diabetes, chronic obstructive pulmonary disease, disseminated cancer, chronic steroid use, bleeding disorder, length of surgery, and any postoperative complication prior to discharge. We evaluated the performance of the score at predicting readmission in a gynecologic oncology population, and additionally sought to determine if any factors known prior to surgery could replace those that are not known until the time of surgery (operative time and postoperative complication). This was a single-institution retrospective cohort study of women undergoing robotic hysterectomy by a gynecologic oncologist in 2018. Associations between pre-operative, operative and post-operative factors and 30-day readmission, SDD and postoperative complications were assessed using logistic regression. The 30-day readmission rate among the 423 women in the cohort was 4.5% and 1.9% in those undergoing SDD. Readmission rates by LHRS were: score 1 (4.9%), score 2 (7.8%), score 3 (13.6%), score 4 (16.7%). Patients with a LHRS of ≥3 had higher odds of readmission compared to those with a lower score (OR 4.20, p = 0.02). Infectious morbidity accounted for the majority of postoperative complications, emergency room visits and readmissions. We did not identify preoperative factors to replace the intra- and post-operative factors used in the score. The readmission rate following MIH is low, and a LHRS of ≥3 is associated with increased risk of readmission. Our findings support the applicability of the LHRS to a gynecologic oncology population; addressing risk factors for postoperative infection or closer follow up for patients with a LHRS ≥3 could reduce postoperative readmissions. • The LHRS identified patients at higher risk of readmission within a gynecologic oncology population. • A LHRS of 3 or higher is associated with a greater odds of 30-day readmission following minimally invasive hysterectomy. • Targeted interventions or closer follow up for patients with a LHRS of 3 or greater may reduce postoperative readmissions. • Infectious morbidity accounted for the majority of complications, emergency department visits and readmissions. • Efforts to reduce perioperative infectious morbidity could reduce readmission following minimally invasive hysterectomy.

Minimally invasive procurement of uterine grafts for transplantation can decrease living donor recovery time. We examined recipient outcomes for grafts procured by robotic-assisted donor hysterectomies with transvaginal extraction in the Dallas UtErus Transplant Study (DUETS). All 5 grafts were successfully transplanted. Recipients had a median 4.5-hour surgical time, 0.25 L estimated blood loss, and 4-day hospital stay. Four recipients had grade III surgical complications and three had acute cellular rejection. At 18 months, graft viability was 100%, with an 80% live birth rate. This report demonstrates the feasibility and reproducible success of using uterus grafts from living donors who underwent robotic-assisted donor hysterectomy. [ABSTRACT FROM AUTHOR]

Objective: This prospective randomized trial aimed to assess the impact of the uterine manipulator in terms of lymph vascular space invasion (LVSI) in patients undergoing minimally invasive staging for early-stage endometrial cancer. Methods: In this multicentric randomized trial, enrolled patients were randomly allocated in two groups according to the no use (arm A) or the use (arm B) of the uterine manipulator. Inclusion criteria were G1-G2 early-stage endometrial cancer at preoperative evaluation. The variables collected included baseline demographic characteristics, perioperative data, final pathology report, adjuvant treatment, and follow-up. Results: In the study, 154 patients (76 in arm A and 78 in arm B) were finally included. No significant differences were recorded regarding the baseline characteristics. A statistically significant difference was found in operative time for the laparoscopic staging (p=0.005), while no differences were reported for the robotic procedures (p=0.419). The estimated blood loss was significantly lower in arm A (p=0.030). No statistically significant differences were recorded between the two study groups in terms of peritoneal cytology, LVSI (p=0.501), and pattern of LVSI (p=0.790). No differences were detected in terms of overall survival and disease-free survival (p=0.996 and p=0.480, respectively). Similarly, no differences were recorded in the number of recurrences, 6 (7.9%) in arm A and 4 (5.2%) in arm B (p=0.486). The use of the uterine manipulator had no impact on DFS both at univariable and multivariable analyses. Conclusions: The intrauterine manipulator does not affect the LVSI in early-stage endometrial cancer patients undergoing laparoscopic/robotic staging.

In the field of minimally invasive surgery, there is a constant drive to devise and execute the most minimally invasive surgeries possible. By the very nature of laparoscopy and robotic surgery, what one can accomplish with several ports of a given size will invariably be studied and attempted with fewer ports and with ports of smaller sizes. After researching the literature, we were not able to find any single port hysterectomies performed through a port size of smaller than 15 mm. We were able to perform, described here, a technique for performing laparoscopic hysterectomy through a single port of only 11 mm in diameter. We illustrate the technique in the accompanying video and believe the technique to be safe and reproducible. [ABSTRACT FROM AUTHOR]

Purpose: Robotic surgery represents the latest development in the field of minimally invasive surgery and offers many technical advantages. Despite the higher costs, this novel approach has been applied increasingly in gynecological surgery. Regarding the implementation of a new operative method; however, the most important factor to be aware of is patient safety. In this study, we describe our experience in implementing robotic surgery in a German University Hospital focusing on patient safety after 110 procedures. Methods: We performed a retrospective analysis of 110 consecutive robotic procedures performed in the University Hospital of Würzburg between June 2017 and September 2019. During this time, 37 patients were treated for benign general gynecological conditions, 27 patients for gynecological malignancies, and 46 patients for urogynecological conditions. We evaluated patient safety through standardized assessment of intra- and postoperative complications, which were categorized according to the Clavien–Dindo classification. Results: No complications were recorded in 90 (81.8%) operations. We observed Clavien–Dindo grade I complications in 8 (7.3%) cases, grade II complications in 5 (4.5%) cases, grade IIIa complications in 1 case (0.9%), and grade IIIb complications in 6 (5.5%) cases. No conversion to laparotomy or blood transfusion was needed. Conclusion: Robotic surgery could be implemented for complex gynecological operations without relevant problems and was accompanied by low complication rates. [ABSTRACT FROM AUTHOR]

Objective: To compare early surgical outcomes of robotic assisted laparoscopic hysterectomy with laparoscopic hysterectomy for benign diseases, in terms of operation time, estimated blood loss (EBL), perioperative complications, hospital stay and first gas discharge. Material and Methods: Medical records of 146 patients who either underwent laparoscopic (n=84) or robotic assisted laparoscopic hysterectomy (n=62) for benign diseases were extracted from records. Demographic characteristics and operation time, EBL, length of hospital stay and first gas discharge were compared between the groups. Results: Mean age and mean body mass index of both groups were comparable. The difference in the mean EBL was not statistically significant between laparoscopic (91±65 mL) and robotic group (80±37 mL, p=0.43). The difference in the mean first gas discharge time was not statistically different between laparoscopic (15±5 hours) and robotic group (17±6 hours, p=0.33). The length of hospital stay was comparable between groups (1.4±0.5 vs 1.5±0.7 days, p=0.64). The mean operation time was longer for the robotic group (150±180 minimum) when compared with laparoscopic group (105±18 minimum, p<0.01). The mean uterine weight of the robotic group was significantly heavier compared with laparoscopic group (234±157 grams vs 153±119 grams, respectıvely, p<0.01). Conclusion: Early surgical outcomes of robotic assisted laparoscopic and laparoscopic hysterectomy were comparable in terms of EBL, first gas discharge and hospital stay. Operation time was longer for robotic hysterectomy. [ABSTRACT FROM AUTHOR]

Single-site hysterectomy (SSH) laparoscopic or robotic presented distinct advantages with regards to postoperative cosmetic outcome, wound-related complications and morbidity. We aimed to evaluate the feasibility of robotic and laparoscopic SSH in patients with benign or early-stage malignant gynecological conditions and to compare the two approaches. A systematic search of four electronic databases for articles published up to September 2019 was performed. Studies reporting outcomes for women who underwent robotic or laparoscopic SSH were considered eligible. A total of 6 studies with 412 patients were included. Among them, 150 women had robotic SSH, whereas 262 had laparoscopic SSH. Neither total operative time nor total hysterectomy time were found different among the 2 groups (355 patients MD 17.47 min, 95% CI − 5.82 to 40.76, p = 0.14 and 285 patients MD 6.41 min, 95% CI − 10.24 to 23.06, p = 0.45, respectively). Robotic approach presented significantly lower blood loss and hospital stay compared to laparoscopic (287 patients MD − 10.84 ml 95% CI − 20.35 to − 1.32, p = 0.03, 328 patients MD − 0.32 days, 95% CI − 0.44 to − 0.19, p < 0.00001, respectively). No difference was found with regards to major or overall postoperative complications. The present meta-analysis supports the use of robotic SSH, since it was related to faster recovery and comparable operative times and complication rates compared to laparoscopic. Nonetheless, due to the limited number of the included studies and their retrospective nature, the aforementioned outcomes must be interpreted with caution and further larger volume studies are needed in the field.

Identify factors influencing the feasibility and safety of outpatient robotic-assisted hysterectomy for endometrial or cervical carcinoma. A single-institution retrospective chart review of patients who underwent robotic hysterectomy for cervical or endometrial cancer between 2012 and 2016 was performed. Outcomes were measured by length of stay (LOS), which was categorized as an admit-to-discharge time of >12 h or <12 h. Past medical history, surgical history, social history, patient demographics, intraoperative course, and postoperative events were examined as possible factors associated with LOS >12 h. These factors were evaluated using multivariate logistic regression. Readmission rates were compared between the two groups using an independent-samples t -test. Of the 254 patients, 150 (59.1%) had a LOS >12 h and 104 (40.9%) had a LOS < 12 h. The factors associated with a LOS >12 h (p < 0.05) included: Postoperative emesis, inadequate pain control, operating room (OR) time > 180 min, uterine mass > 150 g, start time after 15:00, history of venous thromboembolism (VTE), age > 75 years, body mass index (BMI) 35–40, and post-operative VTE formation. Patients discharged in <12-hours were not more likely than those discharged in >12-hours to be re-admitted (p = 0.92). Robotic hysterectomy for the treatment of endometrial and cervical carcinoma is both feasible and safe in the outpatient setting, as >40% of patients were successfully discharged within 12 h with no increase in readmission. Multiple risk factors were identified for extended hospitalization, offering potential for the development of a risk stratification model to improve the efficacy of outpatient robotic hysterectomy. • Outpatient robotic surgery for treatment of endometrial and cervical cancer appears to be safe and feasible. • Demographic factors requiring readmission were age >75 years, body mass index 35-40, and history of venous thromboembolism. • Intraoperative factors requiring readmission were operative time > 180 minutes, operating start time and uterine mass > 150 grams. • Postoperative factors requiring readmission were postoperative emesis inadequate pain control and post-operative VTE formation.

Introduction: Robotic hysterectomy may offer advantages for complex cases over the conventional laparoscopic approach. Objective: To assess the association of surgical approach (robotic vs conventional) with blood loss, risks of readmission, reoperation, complications, and average operative time. Methods: In a retrospective cohort study, we used the electronic medical records of Kaiser Permanente Northern California, 2011 to 2015, to estimate outcomes of robotic and conventional laparoscopic hysterectomy among women with complex or noncomplex benign disease. Mixed-effects regression models accounted for patient characteristics and surgeon volume. Results: The study included 560 robotic and 6785 conventional laparoscopic cases. Overall, 1836 patients (25%) met criteria for being complex. The average operative time was 152 minutes for robotic hysterectomy and 157 minutes for conventional laparoscopic hysterectomy (p < 0.0001). Complex surgical cases averaged 190 minutes and noncomplex cases averaged 144 minutes. The difference in operative time for high-volume surgeons treating complex patients with robotic hysterectomy vs conventional hysterectomy was 21 minutes faster (p < 0.05). After adjustment, the risk of blood loss at least 51 mL was lower for robotic surgery than for conventional surgery for complex and noncomplex patients. Other than risk of urinary tract complications, we observed no differences in the risks of complications or risk of reoperation between robotic and conventional laparoscopy for complex and noncomplex patients. Conclusion: For women with complex disease, the robotic approach, when used by a higher-volume surgeon, may be associated with shorter operative time and slightly less blood loss, but not with lower risk of complications.

The relationship between muscular tissue oxygen saturation (SmtO2) during surgery and postoperative nausea and vomiting (PONV) remains to be determined. Patients undergoing robotic hysterectomy participated in this prospective cohort study. SmtO2 of the brachioradialis muscle in the forearm was continuously monitored during surgery. Thresholds based on relative changes or absolute values were systematically assigned. The relationship between thresholds and PONV was investigated based on threshold analysis (i.e., exceeding or not exceeding a threshold), area under the curve analysis (i.e., the size of the area enclosed by the SmtO2 trace and threshold), and multivariable analysis by accounting for recognized PONV risk factors. PONV occurred in 35 of 106 patients (33%). Based on the multivariable analysis, the SmtO2 threshold of 20% above baseline correlated with less PONV (OR 0.39; 95% CI 0.16-0.93; p = 0.034), and the following values correlated with more PONV: 5% below baseline (OR 2.37; 95% CI 1.26-4.45; p = 0.007), 20% below baseline (OR 16.08; 95% CI 3.05-84.73; p = 0.001), < 70% (OR 2.86; 95% CI 1.17-6.99; p = 0.021) and < 60% (OR 6.55; 95% CI 1.11-38.53; p = 0.038). Our study suggests that a potential therapeutic goal for PONV prophylaxis may be to maintain SmtO2 at > 70% and above baseline. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to compare the safety and effectiveness of robotic hysterectomy (RH) with conventional laparoscopic hysterectomy (LH) for the treatment of cervical cancer using multivariate regressions.Methods: We designed a retrospective single-center study and consecutively collected patients with cervical cancer from February 2014 to October 2017. Data extraction was performed by two independent researchers. The surgical outcomes include operative time, estimated blood loss, number of lymph nodes, time to first flatus, time to a full diet, time to remove drainage tube, length of hospital stay, and postoperative complication.Results: A total of 152 patients with cervical cancer were collected in our study including 92 patients who underwent RH and 60 patients who underwent LH. Both groups have similar characteristics. The RH group showed shorter operative time (Coe - 42.89; 95% CI - 74.39 to 11.39; P = 0.008) and more number of lymph nodes (Coe 6.06; 95% CI 2.46-9.66; p = 0.001) than the LH group. As for the postoperative parameters, the RH group showed shorter time to remove drainage tube (Coe - 0.89; 95% CI -1.62 to -0.15; p = 0.019) and length of hospital stay (Coe - 6.40; 95% CI - 10.19 to - 2.95; p = 0.001). No significant difference was found between the groups in estimated blood loss (Coe 34.64; 95% CI - 33.08 to 102.37; p = 0.314), time to first flatus (Coe 0.11; 95% CI - 0.38 to 0.61; p = 0.652), time to a full diet (Coe - 0.24; 95% CI - 0.54 to 0.06, p = 0.118), and postoperative complication (OR 0.84; 95% CI 0.35-1.98; p = 0.685).Conclusion: The results from this study suggest that RH is safe and effective as LH but robotic surgery significantly contributed to the feasibility of alternative treatment options for cervical cancer patients.

Objective: There are limited prospective data on the evaluation of quality of life in patients undergoing robotic hysterectomy for endometrial cancer. Our objective was to determine whether post-operative recovery differs between robotic and abdominal hysterectomy. Methods: At a Swedish tertiary referral university hospital, 50 women with low-risk endometrial cancer scheduled for surgery between February 2012 and May 2016 were included in a randomized trial. Surgery was performed according to principles for minimal invasive surgery. Anesthesia and peri-operative care followed a standardized enhanced recovery after surgery program in both groups. The EuroQol Group form EQ-5D and the Short Form-36 were used to evaluate patients' health-related quality of life. The Swedish Postoperative Symptoms Questionnaire assessed symptoms pre-operatively, daily for 7 days from the day of surgery, and then weekly until 6 weeks post-operatively. Data were analyzed by means of non-parametric tests and repeated measures ANOVA. To evaluate the time-dependent occurrence of complications, Kaplan-Meier survival and Cox proportional-hazard models were used. Results: A total of 50 women were enrolled in the study (25 robotic and 25 abdominal hysterectomy). Median age (68 years vs 67 years), estimated blood loss (50 mL vs 50 mL), length of hospital stay de facto (53 hours vs 51 hours), and time to meet discharge criteria (36 hours vs 36 hours) in the robotic and abdominal groups, respectively, did not differ significantly (p>0.05) Women in the robotic hysterectomy group recovered significantly faster (p=0.01) in the EQ-5D health index, and reached their pre-operative level after approximately 3 weeks, nearly 2 weeks earlier than the abdominal group. Differences regarding improvement in health-related quality of life (Short Form-36) were statistically significant in general health and social functioning only, and were in favor of robotic hysterectomy. Consumption of analgesics, pain intensity, and symptom sum score post-operatively were equal. Occurrence of complications was an independent risk factor and influenced significantly the EQ-5D health index, length of hospital stay, pain intensity, opioid consumption, and symptom sum score adversely. Conclusion: Robotic hysterectomy in the setting of an enhanced recovery after surgery program led to faster recovery in health-related quality of life compared with abdominal hysterectomy.

Abstract Objective The aim of this study was to evaluate the surgical and oncological outcome of robotic surgical staging with hysterectomy (RH) plus or less pelvic and aortic lymphadenectomy, compared to the same procedures performed by laparoscopic surgery (LH) in obese patients (BMI≥30 kg/m2) with endometrial cancer. Material and methods From October 2001 to April 2017, obese patients (BMI > 30 kg/m2) with primary, histologically confirmed endometrial carcinoma who underwent LH or RH using the Da Vinci Si or Xi Surgical System® (Intuitive Surgical Inc®, 1266 Kifer Road, Building 101 Sunnyvale, CA) were eligible for the study. Results We identified 655 women with endometrial cancer and BMI >30 kg/m2. Out of 655 patients, 249 (38%) underwent RH and 406 (62%) underwent LH plus or less pelvic and aortic lymphadenectomy. Our study showed that, compared to the 406 patients treated in LPS, 249 patients treated in robotics have a statistically significant difference in terms of increased operating time and a decreased conversion rate. In addition, the rate of pelvic lymphadenectomies in robotic surgeries is twice the one reported in LPS surgeries. Furthermore, a reduction in hospital stay was observed in the robotic group. We observed that the oncological outcomes do not vary according to the surgical approach and BMI variation. Conclusions: robotic surgery in severely obese women with endometrial cancer is feasible, safe, and reproducible and could be a valid alternative to laparoscopy in the treatment of these patients. Prospective studies could confirm our results. [ABSTRACT FROM AUTHOR]

Abstract Objectives To demonstrate the initial experience of robotic hysterectomy to treat benign uterine disease at a university hospital in Brazil. Methods A cross-sectional study was conducted to review data from the first twenty patients undergoing robotic hysterectomy at our hospital. The surgeries were performed from November 2013 to August 2014, all of them by the same surgeon. The patients were reviewed for preoperative characteristics, including age, body mass index (BMI), indications for the hysterectomy and previous surgeries. Data of operative times, complications, postoperative pain and length of hospital stay were also collected. Results The total operating room time was 252.9 minutes, while the operative time was 180.7 minutes and the console time was 136.6 minutes. Docking time was 4.2 minutes, and the average undocking time was 1.9 minutes. There was a strong correlation between the operative time and the patient's BMI (r = 0.670 ; p = 0.001). The console time had significant correlation with the uterine weight and the patient's BMI (r = 0.468; p = 0.037). A learning curve was observed during docking and undocking times. Conclusion Despite its high cost, the robotic surgery is gaining more space in gynecological surgery. By the results obtained in our hospital, this surgical proposal proved to be feasible and safe. Our initial experience demonstrated a learning curve in some ways.

Abstract Objective Compare postoperative pain scores following hysterectomy in patients receiving perioperative celecoxib versus postoperative ketorolac as part of a multimodal pain regimen. Methods Patients undergoing hysterectomy were randomized to receive scheduled intravenous ketorolac in the immediate postoperative period or oral celecoxib prior to surgery and continued for a total seven days. All patients received a common multimodal pain protocol consisting of scheduled acetaminophen, gabapentin, and opioids as needed. Inpatient pain scores and postoperative opioid use were analyzed. A questionnaire regarding outpatient opioid use and return to normal activities of daily living (ADLs) was returned two weeks postoperatively. Results 192 patients were assessed for eligibility and 170 patients were randomized. Enrollment of patients undergoing open hysterectomy was closed prematurely for poor accruement (n = 32). 138 patients undergoing robotic hysterectomy were included were analyzed. There were no differences for inpatient pain scores (2.7 ± 1.9 v. 2.4 ± 1.6, p = 0.21). Average length of stay was similar between the two arms (11.6 ± 8.1 h v. 11.9 ± 7.6 h, p = 0.41). Patients in the celecoxib arm used less prescription opioids (6.0 ± 3.6 v. 8.1 ± 4.0, p = 0.001) and stopped using oral opioids earlier (3.8 ± 2.6 days v. 5.7 ± 2.8 days, p < 0.001). No differences were seen in inpatient opioid or anti-emetic usage, perioperative complications, or days to return to ADLs. Conclusions There was no difference in inpatient pain scores between patients who received celecoxib or ketorolac as part of multimodal pain control following robotic hysterectomy. Patients who received scheduled celecoxib for seven days after surgery used less prescription narcotics. Highlights • There was no difference in inpatient pain scores among patients receiving celecoxib or ketorolac after robotic hysterectomy. • Oral celecoxib continued for seven days after surgery decreased outpatient prescription narcotic use compared to IV ketorolac. • 95% of patients used less than prescription 12 narcotic pills following discharge after robotic hysterectomy.

Objective: This study aims to determine the rate of postoperative venous thromboembolism (VTE) in endometrial cancer patients undergoing robotic hysterectomy with or without extended pharmacologic VTE prophylaxis. Methods/Materials: A retrospective chart review of women undergoing robotic hysterectomy with or without other procedures for endometrial cancer from January 2010 to February 2015 was conducted at 2 institutions. Charts were manually abstracted, and rates of VTE within 30 and 60 days after surgery were determined. Patients were then stratified by those who did and did not receive extended VTE prophylaxis. Results: A total of 403 patients were included, of which 367 patients (91%) received extended pharmacologic prophylaxis and 36 patients (9%) did not. Low molecular weight heparin prescriptions ranged from 7 to 30 days. Patients receiving extended prophylaxis (EP) were older (63 ± 11 vs 57 ± 12; P = 0.004), more frequently underwent lymphadenectomy (67% vs 34%; P < 0.001), and had higher-grade tumors compared with patients not receiving EP. Overall 30-day and 60-day VTE rates were 0.7% and 1.2%, respectively. There were no significant differences in 30-day and 60-day VTE rates among patients that did and did not receive EP, although a trend toward lower VTE rates in the EP group was observed (30-day rates 0.5% vs 2.8% respectively, P = 0.25; 60-day rates 0.8% vs 5.6%, P = 0.07). Conclusions: In this study, 30-day and 60-day VTE rates after minimally invasive surgery for endometrial cancer were low. Rates were also similar to those of previous reports in this setting in which the majority of patients did not receive extended VTE prophylaxis. Given the consistent finding that postoperative VTE in this population is rare regardless of prophylaxis use and the variability in practice patterns for VTE prophylaxis, the development of best practice guidelines for EP use specific to this setting is warranted.

Objective To compare outcomes and cost for patients with endometrial cancer undergoing vaginal hysterectomy (VH) or robotic hysterectomy (RH), with or without lymphadenectomy (LND). Methods Patients undergoing planned VH (and laparoscopic LND) or RH (and robotic LND) between January 2007 and November 2012 were reviewed. Patients with stage IV disease, synchronous cancer, synchronous surgery, or treated with palliative intent were excluded. Patients were objectively triaged to LND per institutional protocol based on frozen section. Outcomes were compared between VH and RH groups matched 1:1 on propensity scores. Results VH was planned in 153 patients; 60 (39%) had concurrent LND while 93 (61%) were low risk and did not require LND. RH was planned in 398 patients; 225 (56%) required concurrent LND and 173 (44%) did not. Among 50 PS-matched pairs without LND, there was no significant difference in complications, length of stay, readmission, or progression free survival. However, median operative time was 1.3 h longer and median 30-day cost $3150 higher for RH compared to VH (both p < 0.001). Among patients requiring LND, 42 PS-matched pairs were identified. Median operative time was not different when pelvic and para-aortic LND was performed, and 12 min longer in the VH group for pelvic LND alone (p = 0.03). Median 30-day cost was $921 higher for RH compared to VH when LND was required (p = 0.08). Conclusion Utilization of vaginal hysterectomy for endometrial cancer results in similar surgical and oncologic outcomes and lower costs compared to RH and should be considered for appropriate patients with a low risk of requiring LND.

Aim This study aimed to evaluate the surgical safety and clinical effectiveness of RH versus LH and laparotomy for cervical cancer. Methods We searched Ovid-Medline, Ovid-EMBASE, and the Cochrane library through May 2015, and checked references of relevant studies. We selected the comparative studies reported the surgical safety (overall; peri-operative; and post-operative complications; death within 30 days; and specific morbidities), and clinical effectiveness (survival; recurrence; length of stay [LOS]; estimated blood loss [EBL]; operative time [OT]) and patient-reported outcomes. Results Fifteen studies comparing RH with OH and 11 comparing RH with LH were identified. No significant differences were found in survival outcomes. The LOS was shorter and transfusion rate was lower with RH compared to OH or LH. EBL was significantly reduced with RH compared to OH. Compared to OH, overall complications, urinary infection, wound infection, and fever were significantly less frequent with RH. The overall, peri-operative, and post-operative complications were similar in other comparisons. Several patient-reported outcomes were improved with RH, though each outcome was reported in only one study. Conclusions RH appears to have a positive effect in reducing overall complications, individual adverse events including wound infection, fever, urinary tract infection, transfusion, LOS, EBL, and time to diet than OH for cervical cancer patients. Compared to LH, the current evidence is not enough to clearly determine its clinical safety and effectiveness. Further rigorous prospective studies with long-term follow-up that overcome the many limitations of the current evidence are needed. [ABSTRACT FROM AUTHOR]
