From cadaveric and animal studies to the clinical reality of robotic mastectomy: a feasibility report of training program

Robotic nipple-sparing mastectomy (RNSM) provides better cosmetic outcomes and improves the quality of life of women with breast cancer. However, this has not been widely adapted due to the lack of well-structured training programs. The present study aimed to report the establishment of cadaveric and animal skill laboratory training programs for RNSM and the participants’ perception on the training programs. We performed 24 RNSMs using 11 cadavers and one porcine model. Then, the skill laboratory characteristics were reviewed. Five trainers and 10 trainees participated in the programs. The first four cadaveric RNSMs with latissimus dorsi flaps and implants were performed using the da Vinci Si® system. We performed 14 and six RNSMs using the Xi® and SP® systems, respectively. The scores for questionnaires on the satisfaction with the training consisted of the trainees’ perceived goals in attending the course, teaching/learning environment, and teaching staff performance. The scores were excellent. Cadaveric or porcine RNSM skill laboratory training may be essential programs that can provide safe and efficient training.

The impact of robotic technology on the learning curve for robot-assisted gastrectomy in the initial clinical application stage.

To evaluate the impact of robotic technology on the learning curve for robot-assisted gastrectomy in the initial clinical application stage and to compare RAG with laparoscopic-assisted gastrectomy using a short-term evaluation. Between September 2016 and December 2018, 111 consecutive distal gastric cancer patients who were candidates for RAG or LAG were prospectively enrolled. Operative findings, morbidity, oncological findings, and the learning curve were analyzed. Thirty patients underwent RAG with the da Vinci Si robot system, and eighty-one patients underwent LAG. Blood loss was lower during RAG than during LAG (133.80 ± 95.28 vs. 178.83 ± 98.37, P = 0.046). The operative time for RAG was significantly longer (304.45 ± 42.08 vs. 281.17 ± 32.69, P = 0.015). The number of retrieved lymph nodes (LNs) was greater (37.33 ± 8.25 vs. 32.78 ± 5.98, P = 0.003) with RAG. Notably, RAG had an advantage in the dissection of No. 9 and 11p LNs (3.56 ± 1.76 vs. 2.78 ± 1.30, P = 0.038; 2.48 ± 0.93 vs. 1.99 ± 0.84, P = 0.015, respectively). Severe complications were less frequent in the RAG group (7 (8.6%) vs. 1 (3.3%), P = 0.003). No significant differences in terms of postoperative recovery were found between the two groups. The learning curve for RAG showed that the cumulative sum value decreased from the 10th case, while it decreased from the 28th case in the LAG group. By means of robotic technology, RAG is better than LAG for the dissection of No. 9 and 11p LNs and for the alleviation of surgical trauma, and the technique is learned more rapidly during the preliminary stage than the LAG technique.

Learning to Calibrate - Estimating the Hand-eye Transformation Without Calibration Objects

Hand-eye calibration is a method to determine the transformation linking between the robot and camera coordinate systems. Conventional calibration algorithms use a calibration grid to determine camera poses, corresponding to the robot poses, both of which are used in the main calibration procedure. Although such methods yield good calibration accuracy and are suitable for offline applications, they are not applicable in a dynamic environment such as robotic-assisted minimally invasive surgery (RMIS) because changes in the setup can be disruptive and time-consuming to the workflow as it requires yet another calibration procedure. In this paper, we propose a neural network-based hand-eye calibration method that does not require camera poses from a calibration grid but only uses the motion from surgical instruments in a camera frame and their corresponding robot poses as input to recover the hand-eye matrix. The advantages of using neural network are that the method is not limited by a single rigid transformation alignment and can learn dynamic changes correlated with kinematics and tool motion/interactions. Its loss function is derived from the original hand-eye transformation, the re-projection error and also the pose error in comparison to the remote centre of motion. The proposed method is validated with data from da Vinci Si and the results indicate that the designed network architecture can extract the relevant information and estimate the hand-eye matrix. Unlike the conventional hand-eye approaches, it does not require camera pose estimations which significantly simplifies the hand-eye problem in RMIS context as updating the hand-eye relationship can be done with a trained network and sequence of images. This introduces a potential of creating a hand-eye calibration approach that is capable of accurately updating the hand-eye matrix according to the changes in RMIS setup.

Although hysterectomy may be performed at the time of POP repair, many women choose to preserve their uterus for reasons of sexuality, female identity, religion, maintenance of maximal vaginal length, and resistance to removal of a normal organ. METHODS: Data is collected from an IRB approved prospectively maintained database of robotic POP repair in an 836 bed tertiary care hospital. The surgery is performed with a da Vinci Si or Xi system with 4 robotic ports and 1 assistant port. Commercially available 4 x 24 cm Y-shaped wide pore polypropylene mesh is modified to accommodate >10 cm anterior and posterior dissections of the vaginal walls. The anterior vaginal wall component is brought through the broad ligament and joined with the posteriorly placed component for attachment to the Anterior Longitudinal Ligament with GoreTex sutures. The mesh is then completely covered by peritoneum. All patients for RASCP-UP had Stage 4 prolapse with maximal anterior, posterior and apical descent with the cervix at the apex of the descent. All patients had normal PAP smears and pelvic ultrasounds. RESULTS: Between 2010 and 2021 a total of 351 patients underwent RASCP at the same institution. Of these, 54 presented with complete vaginal vault eversion requesting RASCP-UP. Mean age was 67.5 years and mean BMI 26.8. Cases were completed with robotic console time between 61 and 121 minutes and all patients discharged within 24-48 hours. At mean 60 month (12–124 month) follow-up, there were no mesh erosions, hernias, or reoperations for prolapse. There was one reoperation for hysterectomy at 6 year follow up for suspected endometrial carcinoma and one reoperation for small bowel obstruction in a patient with extensive lysis of adhesions. Mid-urethral slings were placed at the time of sacrocolpopexy to prevent de novo stress incontinence CONCLUSIONS: RASCP-UP is a reproducible, reliable procedure for patients with severe POP who desire uterus preservation. The surgery restores normal vaginal axis and length without placement of mesh material through vaginal mucosa. Long-term results show durable functional repair. Is the “unnecessary” removal of an otherwise normal uterus “necessary” for repair of POP? For a number of female patients, the answer appears to be no.

Perioperative and Oncologic Outcomes of Single-Port vs Multiport Robot-Assisted Radical Prostatectomy: A Meta-Analysis.

Purpose: Although single-port robot-assisted radical prostatectomy (SP-RARP) is considered a safe and feasible approach for radical prostatectomy, the comparative performance of the SP robot with earlier models, including da Vinci Xi or Si, is elusive. This systematic review summarizes the current evidence on SP-RARP and compares its perioperative, functional, and oncologic outcomes to multiport robot-assisted radical prostatectomy (MP-RARP). Methods: We performed a systematic search in PubMed, Embase, Web of Science, and Cochrane Library database for randomized control trials (RCTs) and non-RCTs that compare SP-RARP to MP-RARP. The primary outcomes included perioperative, functional, oncologic, and painful outcomes. The odds ratio (OR) and weighted mean difference (WMD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CIs). Results: Seven studies, including 1239 patients, were enrolled in the meta-analysis. We reported similar results for SP-RARP and MP-RARP in terms of the operative time, blood loss, continence and potency rates, complication rate, positive surgical margin, and biochemical recurrence. However, hospital stay (WMD -17.86 hours, 95% CI -27.80 to -7.92; p = 0.0004), catheterization time (WMD -1.51 days, 95% CI -2.60 to -0.41; p = 0.007), and the rate of opioid use (OR 0.26, 95% CI 0.13 to 0.53; p = 0.0002) were less with SP-RARP. In addition, more patients did not require any pain medication during the hospital stay with SP-RARP (OR 14.41, 95% CI 5.22 to 39.76; p < 0.00001). Conclusions: SP-RARP is associated with a shorter hospital stay and catheterization time, and the need for postoperative pain medication is lower compared to MP-RARP, with comparable perioperative, functional, and oncologic outcomes.

Use of Bariatric Ports in 4-Arm Robotic Partial Nephrectomy: A Comparative Study With the Standard 3-Arm Technique.

ObjectivesWe aim to compare the outcomes of a 3-arm versus a 4-arm robotic assisted partial nephrectomy (RAPN) using the da Vinci Si model; as well as, illustrate the deployment of long ports to decrease arm collision during the 4-arm approach.Patients and MethodsResults of RAPN in a Middle Eastern tertiary referral center from August 2013 to December 2017 are reported. Comparison between 3 versus 4-arm robotic approaches was done in regards to patient and tumor characteristics, operative parameters, and postoperative outcomes. Statistical analysis was performed with the Student’s t-test and chi-squared test.ResultsForty consecutive 3-arm RAPNs and 40 consecutive 4-arm RAPNs were retrospectively evaluated. Differences in tumor complexity between the two groups were statistically insignificant. Similarly, surgical margin positivity, mean ischemia time, estimated blood loss, length of hospital stay, and mean change in serum creatinine were statistically insignificant between the two groups. Mean operative time was significantly shorter by 42 minutes in the 4-arm vs 3-arm group (p=0.01).ConclusionsThe addition of a 4th arm in RAPN can be of benefit in centers that still rely on the da Vinci Si model. The ease of hilar dissection, retraction, and surgeon independence instigated a statistically significant decrease in operative time with 4-arm use.

Two arms-three instruments robot-assisted laparoscopic hysterectomy: A reproducible technique

Although laparoscopic hysterectomy has been used for more than 3 decades, it is not universally adopted due to steep learning curve. The robotic platform can bridge this gap and reduce the need for open hysterectomy with enhanced dexterity and accurate depth perception by 3D vision and wristed intuitive movements. This technical note introduces a two arms-three instruments “Sinha-Apollo technique” for da Vinci Si system for performing robotic-assisted laparoscopic hysterectomy in simplified and reproducible steps.

Robotic Transanal Surgery. Initial Experience in a Developing Country

Abstract Background Transanal minimally invasive surgery (TAMIS) is a surgical technique used for the excision of rectal neoplasia that gained popularity during the last decade.Due to the technical difficulty (non-articulated instruments, reduced workspace) and the long learning curve associated with this technique, the use of robotic platforms to improve resection results has been suggested and reported, at the same time that the learning curve decreases and the procedure is facilitated Materials and Methods From March 2017 to December 2019, all patients with rectal lesions eligible for TAMIS were offered the possibility to receive a robotic TAMIS (R-TAMIS). We used a transanal GelPoint Path (Applied Medical Inc., Santa Margarita, CA, USA) in the anal canal to be able to do the Da Vinci Si (Intuitive Surgical, Sunnyvale, CA, USA) robotic platform docking, which we used to perform the excision of the rectal lesion as well as the resection site defect. Results Five patients between 34 and 79 years of age underwent R-TAMIS. The mean distance to the anal verge was 8.8 cm. There were no conversions. The mean surgery time was 85 minutes, and the mean docking time was 6.6 minutes. Conclusions Robotic TAMIS is a feasible alternative to TAMIS, with a faster learning curve for experienced surgeons in transanal surgery and better ergonomics. Further studies are needed to assess the cost-benefit relationship.

Robotic single‐site versus multiport radical hysterectomy in early stage cervical cancer: An analysis of 62 cases from a single institution

BackgroundThis study aimed to compare the surgical outcomes and cost of robotic single‐site radical hysterectomy (RSSRH) versus robotic multiport radical hysterectomy (RMPRH) with pelvic lymph node dissection in early stage cervical cancer.MethodsSixty‐two patients with early stage cervical cancer were recruited between November 2011 and July 2017 and underwent RSSRH (20 patients) and RMPRH (42 patients) for early stage cervical cancer using the da Vinci Si Surgical System (Intuitive Surgical).ResultsThere were no significant difference between the two groups in most of parameters. However, postoperative hospital discharge and total hospital costs for RSSRH were significantly shorter than RMPRH (both p < 0.001). However, lymph node retrieval of RMPRH was significantly higher than RSSRH in (18.0 vs. 9.5, respectively; p < 0.001).ConclusionsRSSRH has comparable surgical outcomes to the RMPRH method. RSSRH could be considered a surgical option in a well‐selected patient group.

Extraperitoneal Robotic Laparo-Endoscopic Single-Site Plus1-Port Radical Prostatectomy Using the da Vinci Single-Site Platform.

Currently, over 80% of radical prostatectomies have been performed with the da Vinci Surgical System. In order to improve the aesthetic outlook and decrease the morbidity of the operation, the new da Vinci Single Port (SP) system was developed in 2018. However, one major problem is the SP system is still not available in most countries. We aim to present our initial experience and show the safety and feasibility of the single-site robotic-assisted radical prostatectomy (LESS-RP) using the da Vinci Single-Site platform. From June 2017 to January 2020, 120 patients with localized prostate cancer (stage T1–T3b) at Kaohsiung Medical University Hospital were included in this study. We describe our technique and report our initial results of LESS-RP using the da Vinci Si robotic system. Preoperative, intraoperative and postoperative patient variables were recorded. Prostate-specific antigen (PSA)-free survival was also analyzed. A total of 120 patients were enrolled in the study. The median age of patients was 68 years (IQR 63–71), with a median body mass index of 25 kg/m2 (IQR 23–27). The median PSA value before operation was 10.7 ng/mL (IQR 7.9–21.1). The median setup time for creat-ing the extraperitoneal space and ports document was 25 min (IQR 18–34). The median robotic console time and operation time were 135 min (IQR 110–161) and 225 min (IQR 197–274), respectively. Median blood loss was 365 mL (IQR 200–600). There were 11 (9.2%) patients who experienced complications (Clavien–Dindo classification Gr II). The me-dian catheter duration was 8 days (IQR 7–9), with a median of 10 days (IQR 7–11) of hospital stay. The PSA free-survival rate was 86% at a median 19 months (IQR 6–28) of follow up. Robotic radical prostatectomy using the da Vinci Single-Site platform system is safe and feasible, with acceptable outcomes.

Learning curve of robotic portal lobectomy for pulmonary neoplasms: A prospective observational study.

BackgroundWe aim to assess the learning curve of robotic portal lobectomy with four arms (RPL‐4) in patients with pulmonary neoplasms using prospectively collected data.MethodsData from 100 consecutive cases with lung neoplasms undergoing RPL‐4 were prospectively accumulated into a database between June 2018 and August 2019. The Da Vinci Si system was used to perform RPL‐4. Regression curves of cumulative sum analysis (CUSUM) and risk‐adjusted CUSUM (RA‐CUSUM) were fit to identify different phases of the learning curve. Clinical indicators and patient characteristics were compared between different phases.ResultsThe mean operative time, console time, and docking time for the entire cohort were 130.6 ± 53.8, 95.5 ± 52.3, and 6.4 ± 3.0 min, respectively. Based on CUSUM analysis of console time, the surgical experience can be divided into three different phases: 1–10 cases (learning phase), 11–51 cases (plateau phase), and >51 cases (mastery phase). RA‐CUSUM analysis revealed that experience based on 56 cases was required to truly master this technique. Total operative time (p < 0.001), console time (p < 0.001), and docking time (p = 0.026) were reduced as experience increased. However, other indicators were not significantly different among these three phases.ConclusionsThe RPL‐4 learning curve can be divided into three phases. Ten cases were required to pass the learning curve, but the mastery of RPL‐4 for satisfactory surgical outcomes requires experience with at least 56 cases.

First two-stage robotic ALPPS in HCC patients with hepatic vein invasion: a step-by-step procedure from a clinical case

BackgroundThe associating liver partitioning and portal vein occlusion for staged hepatectomy (ALPPS) procedure is gaining interest because it brings hope to patients who cannot undergo radical surgical resection due to insufficient remnant liver volume. However, the indications and technical aspects of this procedure are still under debate. This report demonstrates the technical aspects of the first two-stage robotic ALPPS for HCC.Case presentationA 55-year-old man with type II portal vein variation was diagnosed with hepatocellular carcinoma. Preoperative 3D reconstruction of the liver based on CT showed a future liver remnant/standard liver volume (FLR/SLV) of 24.45%. The ALPPS procedure was performed using the da Vinci Si system. At the first stage of the operation, we removed the gallbladder and ligated the right anterior branch of the portal vein and the right posterior branch. Following blocking of the hepatic hilum, the liver parenchyma was removed 1 cm away from the right side of the falciform ligament in an incision manner from the top to the bottom and from shallow to deep. The second-stage operation was performed on the 12th postoperative day with a FLR/SLV of 45.13%. During this step, the right hemiliver plus left medial section was separated and removed. Postoperative pathology showed a negative margin. The operative times were 195 and 217 min, respectively. Estimated blood loss was 250 and 500 ml, respectively. There was no need for transfusion or hospitalization in intensive care. The patient was discharged on the 6th postoperative day. Recovery was uneventful after both stages, and the patient did not present any sign of liver failure. Elevation of liver enzymes was minimal. The patient had no evidence of the disease 14 months after the procedure.ConclusionsThe two-stage robotic ALPPS procedure is a safe and feasible technique for select patients with HCC.

The standardized technique in robotic radical antegrade modular pancreatosplenectomy using the flip-up approach.

Radical antegrade modular pancreatosplenectomy (RAMPS) was first introduced in 2003. It has been accepted as an alternative technique for pancreatic cancer of the body and tail. However, robotic RAMPS is not yet popular because of its technical difficulty and lack of standardized technique. This study describes in detail the standard steps of robotic RAMPS using the flip-up approach with the benefit of a robotic view when treating pancreatic cancer of the body and tail. We took advantage of our single-center experience to provide a step-by-step technique of robotic RAMPS procedure using the da Vinci Si system. We divided the procedure into 11 key steps. The surgical steps are optimized to achieve margin-negative curative resection and sufficient regional lymphadenectomy. The artery-first approach is usually used to determine tumor resectability early before performing an irreversible operative step. We also determine the borders of surgical resection and divide the splenic artery after dividing the pancreatic neck and the splenic vein, which facilitates a complete lymphadenectomy around the celiac axis with a bottom-up view. Robotic RAMPS using the flip-up approach is safe and feasible in performing curative resection for well-selected pancreatic cancer of the body and tail. A randomized controlled trial comparing open and robotic RAMPS is needed in the future.

Experiences of a \u201cCOVID protected\u201d robotic surgical centre for colorectal and urological cancer in the COVID-19 pandemic

The recent COVID-19 pandemic led to the cancellation of elective surgery across the United Kingdom. Re-establishing elective surgery in a manner that ensures patient and staff safety has been a priority. We report our experience and patient outcomes from setting up a “COVID protected” robotic unit for colorectal and renal surgery that housed both the da Vinci Si (Intuitive, Sunnyvale, CA, USA) and the Versius (CMR Surgical, Cambridge, UK) robotic systems. “COVID protected” robotic surgery was undertaken in a day-surgical unit attached to the main hospital. A standard operating procedure was developed in collaboration with the trust COVID-19 leadership team and adapted to national recommendations. 60 patients underwent elective robotic surgery in the initial 10-weeks of the study. This included 10 colorectal procedures and 50 urology procedures. Median length of stay was 4 days for rectal cancer procedures, 2 days less than prior to the COVID period, and 1 day for renal procedures. There were no instances of in-patient coronavirus transmission. Six rectal cancer patients waited more than 62 days for their surgery because of the initial COVID peak but none had an increase T-stage between pre-operative staging and post-operative histology. Robotic surgery can be undertaken in “COVID protected” units within acute hospitals in a safe way that mitigates the increased risk of undergoing major surgery in the current pandemic. Some benefits were seen such as reduced length of stay for colorectal patients that may be associated with having a dedicated unit for elective robotic surgical services.

Radical prostatectomy technique in the robotic evolution: from da Vinci standard to single port\u2014a single surgeon pathway

To describe perioperative outcomes following robot-assisted prostatectomy performed by a single surgeon during transitions between da Vinci standard/Si/Xi and the single port. Perioperative data were retrospectively evaluated of the first 40 consecutive robot-assisted radical prostatectomies performed by a single surgeon using the da Vinci standard, Si, Xi and single port. A total of 160 patients were included. We matched standard vs Si (Match 1), Si vs Xi (Match 2) and Xi vs single port (Match 3) cohort. Mann–Whitney and Fisher’s tests were used to test the difference among the groups. Univariate and multivariate logistic regression analyses were adopted to evaluate the predictors of overall and major complications. Single-port procedures in Match 3 showed significant shorter median operative time than Xi. Both Si and single-port groups showed significantly less median blood loss, a shorter median length of stay, respectively, than standard group in Match 1 and than Xi group in Match 3. 1 standard group patient required conversion to open surgery for an unsolvable conflict of the robotic arms. No other intraoperative complications were noted. On univariate and multivariate analyses, the da Vinci platform model was not a predicting factor of major complications (Clavien–Dindo ≥ 3). We described how technological progress impacted peri and postoperative outcomes during transitions between robotic surgical platforms for radical prostatectomy. In particular, the technological improvements associated to the increased surgeon’s expertise made the transition to the single port safe and effective when compared with previous platforms.

Robot-Assisted Laparoscopic Living Donor Nephrectomy: The University of Florence Technique.

Objective: To provide a step-by-step overview of the University of Florence technique for robotic living donor nephrectomy (LDN), focusing on its technical nuances and perioperative outcomes.Methods: A dedicated robotic LDN program at our Institution was codified in 2012. Data from patients undergoing robotic LDN from 2012 to 2019 were prospectively collected. All robotic LDNs were performed by a highly experienced surgeon, using the da Vinci Si robotic platform in a three-arm configuration. In this report we provide a detailed overview of our surgical technique for robotic LDN. The main objective of the study was to evaluate the technical feasibility and safety of the technique, including perioperative surgical complications rate and mid-term functional outcomes.Results: Overall, 36 patients undergoing robotic LDNs were included in the study. Of these, 28 (78%) were left LDNs. Median (IQR) donor pre-operative eGFR was 88 (75.6–90) ml/min/1.73 m2. In all cases, robotic LDN was completed without need of conversion. The median (IQR) overall operative time was 230 (195–258) min, while the median console time was 133 (IQR 117-166) min. The median (IQR) warm ischemia time was 175 (140–255) s. No intraoperative adverse events or 90-d major surgical complications were recorded. At a median (IQR) follow-up of 24 months (IQR 11-46), median (IQR) eGFR patients undergoing in living donor nephrectomy was 57.4 (47.9; 63.9) ml/min/1.73 m2.Conclusions: In our experience, robotic LDN is technically feasible and safe. The use of robotic surgery for LDN may provide distinct advantages for surgeons while ensuring optimal donors' perioperative and functional outcomes.

Technical essential aspects in robotic colorectal surgery: mastering the Da Vinci Si and Xi platforms.

laparoscopy surgery has many proven clinical advantages over conventional surgery and more recently, robotic surgery has been the emerging platform in the minimally invasive era. In the colorectal field, although overcoming limitations of standard laparoscopy, robotic surgery still faces challenging situations even by the most experienced colorectal surgeons. This study reports essentials technical aspects and comparison between Da Vincis Si and Xi platforms aiming to master and maximize efficiency whenever performing robotic colorectal surgery. this study overviews the most structured concepts and practical applications in robotic colorectal surgery in both Si and Xi Da Vinci platforms. Possible pitfalls are emphasized and step-wise approach is described from port placement and docking process to surgical technique. We also present data collected from a prospectively maintained database. our early experience includes forty-four patients following a standardized total robotic left-colon and rectal resection. Guided information and practical applications for a safe and efficient robotic colorectal surgery are described. We also present illustrations and describe technical aspects of a standardized procedure. performing robotic colorectal surgery is feasible and safe in experienced surgeons hands. Although the Da Vinci Xi platform demonstrates greater versatility in a more user-friendly design with technological advances, the correct mastery of technology by the surgical team is an essential condition for its fully robotic execution in a single docking approach.

Robotic Roux-en-Y gastric bypass: surgical technique and short-term experience from 329 cases.

minimally invasive bariatric surgery is clearly superior over open procedures including better early outcomes. Different surgical approaches are used to treat the severely obese, having Roux-en-Y gastric bypass (RYGB) being a highly frequent procedure. Robotic surgery overcomes some laparoscopic limitations adding ergonomics, articulating instruments and a three-dimensional high definition camera. Based on our vast robotic experience, we present our referred group case series and a standardized Robotic Roux-en-Y gastric bypass (rRYGB) technique as well as its outcomes. a review of a prospective maintained database was conducted in patients submitted to robotic Roux en Y bariatric surgery between April 2015 and July 2019. Surgical technique is described and illustrated. We also reported patients demographics, outcomes and its follow-up. a Retrospective analysis identified 329 patients submitted to Robotic Roux-en-Y gastric bypass. Both da Vinci Si and Xi platforms were used. Mean age was 34.4 years, with median BMI of 44.2 kg/m2. Mean console time was 102 min and there was no conversion. No surgical hospital readmission rates were seen in the first 30 days. this study represents our initial experience of robotic Roux-en-Y gastric bypass (rRYGB), its short outcomes and a standardized surgical technique. Our results encourage that rRYGB is technically feasible and safe, and might offer some advantages showing good outcomes and minimal complications.

First report comparing the two types of single-incision robotic sacrocolpopexy: Single site using the da Vinci Xi or Si system and single port using the da Vinci SP system

ObjectiveThe gold standard procedure for treating patients with apical pelvic organ prolapse (POP) is sacrocolpopexy. However, no report comparing the two types of single-incision robotic sacrocolpopexy, namely, single-site robotic sacrocolpopexy (SS-RSC) and single-port robotic sacrocolpopexy (SP-RSC) exists. Therefore, we compared the safety and effectiveness of SS-RSC and SP-RSC. Materials and methodsIn this study, 48 patients who underwent single-incision RSC, 40 non-consecutive patients who underwent SS-RSC, and 8 consecutive patients who underwent SP-RSC for symptomatic POP quantification stage III–IV and were eligible for the 1-year follow-up (FU) were included. We compared the surgical time and operative outcomes of SS-RSC and SP-RSC. We also compared the data of the initial 8 cases in each group. ResultsThe mean patient age was 59.2 ± 11.0 years and 66.1 ± 8.0 years in the SS-RSC (n = 40) and SP-RSC (n = 8) groups, respectively. The mean operative time (OT) and console time were comparable between the SS-RSC and SP-RSC groups (135.3 ± 31.6 min vs 141.8 ± 23.5 min; 94.6 ± 32.2 min vs 89 ± 9.5 min, respectively). The docking time and cervix suturing time were short in the SP-RSC group (P < 0.05). However, in the analysis of the initial 8 cases in each group, all surgical times except the cervix suturing time were shorter in the SP-RSC group (P < 0.05). Three cases had intraoperative bladder injury (two [5.0%] in the SS-RSC and one [12.5%] in the SP-RSC group). Two cases (5.0%) had umbilical incisional hernia in the SS-RSC group. Two cases had vaginal mesh erosion on the posterior vaginal wall, with 1 case in each group. One case (2.5%) experienced a recurrence of POP; an anterior compartment POP-Q stage 2 following SS-RSC at the 4-week FU. ConclusionSingle-incision RSC, both SS-RSC and SP-RSC, is a feasible and effective surgical option for treating symptomatic apical POP with an aesthetic finish.

A comparison of perioperative outcomes between extraperitoneal robotic single-port and multiport radical prostatectomy with the da Vinci Si Surgical System.

To evaluate outcomes between extraperitoneal robotic single-port radical prostatectomy (epR-spRP) and extraperitoneal robotic multiport radical prostatectomy (epR-mpRP) performed with the da Vinci Si Surgical System, comparison was performed between 30 single-port (SP group) and 26 multiport (MP group) cases. Comparisons included operative time, estimated blood loss (EBL), hospital stay, peritoneal violation, pain scores, scar satisfaction, continence, and erectile function. The median operation time and EBL were not different between the two groups. In the SP group, the median operation time of the first 10 patients was obviously longer than that of the latter 20 patients (P < 0.001). The median postoperative hospital stay in the SP group was shorter than that in the MP group (P < 0.001). The rate of peritoneal damage in the SP group was less than that in the MP group (P = 0.017). The pain score and overall need for pain medications in the SP group were lower than those in the MP group (P < 0.001 and P = 0.015, respectively). Patients in the SP group were more satisfied with their scars than those in the MP group 3 months postoperatively (P = 0.007). At 3 months, the cancer control, recovery of erectile function, and urinary continence rates were similar between the two groups. It is safe and feasible to perform epR-spRP using the da Vinci Si surgical system. Therefore, epR-spRP can be a treatment option for localized prostate cancer. Although epR-spRP still has a learning curve, it has advantages for postoperative pain and self-assessed cosmesis. In the absence of the single-port robotic surgery platform, we can still provide minimally invasive surgery for patients.
