BACKGROUND: The Laparoscopic Approach to Cervical Cancer (LACC) study results revolutionized our understanding of the best surgical management for this disease. Following its publication, guidelines state that the standard and recommended approach for radical hysterectomy is with an open abdominal approach. Nevertheless, the impact of the LACC trial on real-world changes in the surgical approach to radical hysterectomy remains elusive.
OBJECTIVE: We aimed to study the trends and routes of radical hysterectomies and to evaluate post-operative complication rates before and after the LACC trial (2018).
METHODS: The National Surgical Quality Improvement Program registry was used to examine radical hysterectomies performed for cervical cancer between 2012-2022. We excluded vaginal radical hysterectomies and simple hysterectomies. The primary outcome measures were the trends in route of surgery [minimally invasive surgery (MIS) vs. laparotomy] and surgical complications rate, stratified by periods before and after the publication of the LACC trial in 2018 (2012-2017 vs. 2019-2022). The secondary outcome measure was major complications associated specifically with the different routes of surgery.
RESULTS: Of the 3,611 patients included, 2,080 (57.6%) underwent laparotomy and 1,531 (42.4%) underwent MIS radical hysterectomy. There was a significant increase in the MIS approach from 2012 to 2017 (45.6% MIS in 2012 to 75.3% MIS in 2017, p<.001), and a significant decrease in MIS from 2018 to 2022 (50.4% MIS in 2018 to 11.4% MIS in 2022, p<.001). The rate of minor complications was lower in the period before the LACC trial [317 (16.9%) vs. 288 (21.3%), p=.002]. Major complications rate was similar before and after the LACC trial [139 (7.4%) vs. 78 (5.8%), p=.26]. The rates of blood transfusions and superficial surgical site infections were lower in the period before the LACC trial [137 (7.3%) vs. 133 (9.8%), p=.012 and 20 (1.1%) vs. 53 (3.9%), p<.001, respectively]. In a comparison of MIS vs. laparotomy radical hysterectomy during the entire study period, patients in the MIS group had lower rates of minor complications [190 (12.4%) vs. 472 (22.7%), p<.001] and the rate of major complications was similar in both groups [100 (6.5%) in the MIS group vs. 139 (6.7%) in the laparotomy group, p=.89]. In a specific complications analysis, the rates of blood transfusion and superficial surgical site infections were lower in the MIS groups (2.4% vs. 12.7%, and 0.6% vs. 3.4%, p<.001 for both comparisons) and the rate of deep incisional surgical site infections was lower in the MIS group (0.2% vs. 0.7%, p=.048). In a multiple logistic regression analysis, the route of radical hysterectomy was not independently associated with occurrence of major complications [aOR 95% CI 1.02 (0.63-1.65)].
CONCLUSIONS: While the proportion of MIS radical hysterectomy decreased abruptly following the LACC trial, there was no change in the rate of major post-operative complications. In addition, hysterectomy route was not associated with major post-operative complications.

UNASSIGNED: Robotic-assisted total knee arthroplasty (RATKA) has been reported to enhance operative decision-making. The purpose of this study was intended to assess the predictive accuracy of bone cuts, lower limb alignment, and component size of a novel system for RATKA preoperatively and intraoperatively.
UNASSIGNED: Preoperatively planned bone cuts, limb alignment, and component size were projected using a reconstructed 3D model. Intraoperative bone cuts and postoperative limb alignment were measured. Errors between planned and real bone cuts, limb alignment, and component size were compared.
UNASSIGNED: The mean absolute errors for bone cuts and alignment were within 1.40mm/1.30° with a standard deviation (SD) of 0.96mm/1.12°. For all errors of bone cuts and alignment compared with the plan, there were no statistically significant differences except for the lateral distal of femoral cuts (P=0.004). The accuracy for predicting the femoral, tibial, and polyethylene component sizes was 100% (48/48), 90% (43/48), and 88% (42/48), respectively. Regarding all mean absolute errors of bone cuts and alignments, no significant differences were observed among surgeons.
UNASSIGNED: The novel robotically-assisted system for RATKA donated reliable operative decision-making based on the predictive accuracy regardless of the surgeon\'s level of experience.

OBJECTIVE: Over the last two decades, the use of robotic surgery in cardiac procedures has become increasingly prevalent. Typically, assessments of patient outcomes for robot-assisted surgery concentrate on patient morbidity and mortality, surgical complications, and length of hospital stay. However, there is limited research on patients\' perceptions of robot-assisted surgery. Therefore, this study aims to determine the experiences of patients undergoing robot-assisted cardiac surgery.
METHODS: The study used a qualitative design.
METHODS: The study was conducted with 12 patients who underwent robot-assisted heart surgery at an educational and research hospital. Ethical approval and written informed consent were obtained before the study.
RESULTS: 66.7% of the participants were male with an average age of 38.25 ± 16.06 years. The analysis of qualitative data identified three themes: Robotic surgery, Post-Surgical Experience, and Homecoming.
CONCLUSIONS: Patients expressed satisfaction with robotic surgery and recommended it to others undergoing surgery. Based on the findings, we may suggest that nurses may conduct personalized education programs about robotic surgery and develop programs to follow up with patients at home.

BACKGROUND: A growing importance has been placed on development of trainee robotic surgical skills through simulation curricula and intraoperative experience. However, few studies have examined how console case type impacts learning outcomes. We sought to evaluate how intraoperative coaching and resident autonomy differ based on the use of a single- versus dual-console robot.
METHODS: Robotic single- and dual-console cases from February to September 2023 at a single institution were included. Faculty and trainees wore microphones to capture audio during the case. Pre/post surveys were administered, which included metrics on faculty coaching based on the Wisconsin Surgical Coaching Rubric (WiSCoR) and on trainee technical performance based on the Global Evaluative Assessment of Robotic Skills (GEARS). Statistical analysis of survey data was performed using SPSS. Audio from cases was coded by 2 researchers with a deductive approach using WiSCoR as a framework.
RESULTS: Data were collected for 7 (38.9%) single and 11 (61.1%) dual-console cases across 9 case types from 4 surgical specialties. Chi-square analysis demonstrated no significant difference in percentage of case trainee spent in the operating surgeon role based on trainee level or console case type. Independent t-tests showed no significant difference in trainee autonomy, trainee performance, or faculty coaching scores based on console case type. Trainees rated faculty highest in WiSCoR Domains 1 (sharing responsibility) and 3 (providing constructive feedback). Qualitative analysis showed that for single-console cases, Domain 4 (goal setting) was most represented (34.0% of comments), while for dual-console cases, Domain 1 was most represented (37.0% of comments).
CONCLUSIONS: Qualitative analysis highlights that despite similar survey-based faculty ratings across domains, coaching on self-reflection (Domain 2) is infrequently done, highlighting an opportunity for improvement in this area of coaching during robotic surgery.

Although the safety and short-term outcomes of robotic surgery for sigmoid colon and rectal cancer patients are well-documented, there is limited research on the long-term survival outcomes of robotic colorectal surgery. This is a retrospective study that includes 502 patients who underwent either laparoscopic or robotic anterior resection and abdominoperineal resection for rectal or sigmoid colon cancer between August 2016 and September 2021. All patients were diagnosed with rectal or sigmoid colon adenocarcinoma. Propensity score matching (PSM) was implemented to minimize selection bias. Perioperative outcomes, complication rates, and pathological data were evaluated and compared. The 5-year overall survival rate and disease-free survival rate were calculated and compared. Before matching, patients in the robotic group had earlier pathological T and N stages and were more likely to have received neoadjuvant chemoradiotherapy compared to the laparoscopic group. After matching, most clinicopathological outcomes were similar between the two groups, but the robotic group had longer operative times and a lower conversion rate to open surgery compared with laparoscopic group. After matching for clinical factors, the 5-year DFS rates were 88.19% for the robotic group and 82.46% for the laparoscopic group (P = 0.122), and the OS rates were 90.5% and 79.5% (P = 0.342), showing no significant differences. In the stratified analysis, patients in the robotic surgery group had significantly higher 5-year DFS rates in the following subgroups: age < 65 years, TNM stage I-II, received neoadjuvant therapy, and primary tumor located in the rectum. The safety and efficacy of robotic surgery for sigmoid colon and rectal cancer were validated compared to laparoscopic surgery, with both groups of patients exhibiting comparable long-term prognoses.

(1) Background: In recent years, there has been a change in practice for diverting stomas in rectal cancer surgery, shifting from routine diverting stomas to a more selective approach. Studies suggest that the benefits of temporary ileostomies do not live up to their risks, such as high-output stomas, stoma dysfunction, and reoperation. (2) Methods: All rectal cancer patients treated with a robotic resection in a single tertiary colorectal centre in the UK from 2013 to 2021 were analysed. In 2015, our unit made a shift to a more selective approach to temporary diverting ileostomies. The cohort was divided into a routine diversion group treated before 2015 and a selective diversion group treated after 2015. Both groups were analysed and compared for short-term outcomes and morbidities. (3) Results: In group A, 63/70 patients (90%) had a diverting stoma compared to 98/135 patients (72.6%) in group B (p = 0.004). There were no significant differences between the groups in anastomotic leakages (11.8% vs. 17.8%, p = 0.312) or other complications (p = 0.117). There were also no significant differences in readmission (3.8% vs. 2.6%, p = 0.312) or reoperation (3.8% vs. 2.6%, p = 1.000) after stoma closure. After 1 year, 71.6% and 71.9% (p = 1.000) of patients were stoma-free. One major reason for the delay in stoma reversal was the COVID-19 pandemic, which only occurred in group B (0% vs. 22%, p = 0.054). (4) Conclusions: A more selective approach to diverting stomas for robotic rectal cancer patients does not lead to more complications or leaks and can be considered in the treatment of rectal cancer tumours.

UNASSIGNED: To explore the method of preventing heat steam induced skin damage in robotic nipple-sparing mastectomy and immediate breast reconstruction (R-NSM-IBR) using Da Vinci Robots.
UNASSIGNED: A clinical data of 128 female patients with breast cancer, who were treated with R-NSM-IBR between September 2022 and December 2023 and met the selection criteria, was retrospectively analyzed. During robotic nipple-sparing mastectomy, the breasts were covered with gauze cooled by ice water to reduce skin temperature in 99 cases (group A) and were not treated in 29 cases (group B). There was no significant difference in the age, affected side, body mass index, pathological type of breast cancer, and constituent ratios of adjuvant chemotherapy and neoadjuvant chemotherapy between the two groups ( P>0.05). Intraoperative breast skin temperature, unilateral robotic nipple-sparing mastectomy time, and the incidence of complications of breast heat steam induced skin damage were recorded.
UNASSIGNED: The time for unilateral robotic nipple-sparing mastectomy was (77.18±9.23) minutes in group A and (76.38±12.88) minutes in group B, with significant difference between the two groups ( P<0.05). The intraoperative breast skin temperature was significantly lower in group A than in group B [(25.61±0.91)℃ vs (33.38±1.14)℃; P<0.05]. Seven cases of heat steam skin damage occurred during operation, including 2 cases (2.0%) in group A and 5 cases (17.2%) in group B, with a significant difference in incidence between the two groups ( P<0.05). Among them, 1 patient in group B had a vesication rupture and infection, which eventually led to the removal of the implant; the rest of the patients were treated with postoperative interventions for skin recovery.
UNASSIGNED: The use of breast covered with gauze cooled by ice water during R-NSM-IBR can effectively reduce the risk of heat steam induced skin damage.

BACKGROUND: Postoperative delirium (POD) often occurs in oncology patients, further increasing the medical and financial burden. Robotic technology in lower abdominal tumors resection reduces surgical trauma but increases risks such as carbon dioxide (CO2) absorption. This study aimed to investigate the differences in their occurrence of POD at different end-tidal CO2 levels.
METHODS: This study was approved by the Ethics Committee of Affiliated Hospital of He Bei University (HDFY-LL-2022-169). The study was registered with the Chinese Clinical Trials Registry on URL: http://www.chictr.org.cn , Registry Number: ChiCTR2200056019 (Registry Date: 27/08/2022). In patients scheduled robotic lower abdominal tumor resection from September 1, 2022 to December 31, 2022, a comprehensive delirium assessment was performed three days postoperatively using the CAM scale with clinical review records. Intraoperative administration of different etCO2 was performed depending on the randomized grouping after intubation. Group L received lower level etCO2 management (31-40mmHg), and Group H maintained the higher level(41-50mmHg) during pneumoperitoneum. Data were analyzed using Pearson Chi-Square or Wilcoxon Rank Sum tests and multiple logistic regression. Preoperative mental status score, alcohol impairment score, nicotine dependence score, history of hypertension and diabetes, duration of surgery and worst pain score were included in the regression model along with basic patient information for covariate correction analysis.
RESULTS: Among the 103 enrolled patients, 19 (18.4%) developed postoperative delirium. The incidence of delirium in different etCO2 groups was 21.6% in Group L and 15.4% in Group H, respectively, with no statistical differences. In adjusted multivariate analysis, age and during of surgery were statistically significant predictors of postoperative delirium. The breath-hold test was significantly lower postoperatively, but no statistical differences were found between two groups.
CONCLUSIONS: With robotic assistant, the incidence of postoperative delirium in patients undergoing lower abdominal tumor resection was not modified by different end-tidal carbon dioxide management, however, age and duration of surgery were positively associated risk factors.

BACKGROUND: The da Vinci surgical systems (X and Xi) are fourth-generation systems marketed by Intuitive Inc. The X system is less expensive than the Xi system. This study compared the surgical outcomes of patients who underwent hysterectomy using the X and Xi systems.
METHODS: Data from 172 patients who underwent robot-assisted total hysterectomies by four surgeons between April 2019 and March 2023 were retrospectively analyzed in a single-center study. The patients were divided into two groups based on the surgical system used. Approval was granted by the Institutional Review Board of the Tottori University Hospital (22A134). All patients provided opt-out consent in accordance with the institutional guidelines.
RESULTS: Operative time (126.6 ± 29.5 for X, 138.2 ± 38.5 for Xi, p = .227) and console time (92.9 ± 27.0 for X, 105.5 ± 34.7 for Xi, p = .089) were insignificantly shorter in group X than in group Xi after propensity score matching for age, body mass index, nulliparity, previous history of abdominal or pelvic surgery, preoperative diagnosis, and surgical approach. No significant differences between X and Xi were observed in a subgroup analysis of patients who underwent robot-assisted total laparoscopic hysterectomy without lymphadenectomy (operative time: 199.0 ± 26.5 for X, 221.5 ± 45.1 for Xi, p = .227; console time: 162.1 ± 25.0 for X, 178.3 ± 0.314 for Xi, p = .314).
CONCLUSIONS: Perioperative outcomes for the X and Xi da Vinci surgical systems were equivalent. The cost-effective X system may allow the widespread use of robotic surgeries.
