ABSTRACT
The Da Vinci single port® (SP) robotic platform heralds a new era of minimally invasive surgery (MIS). The primary objective of this study was to assess short-term outcomes in patients undergoing SP robotic hysterectomy with concomitant sacrocolpopexy for pelvic organ prolapse (POP). We performed a retrospective case series at two tertiary care centers between January 2021 and August 2023. Patients with POP electing to undergo SP robotic hysterectomy with concomitant sacrocolpopexy were included. Chart abstraction was used to collect patient demographics and clinical outcomes. Recurrent POP was defined as new bothersome vaginal bulge symptoms and evidence of POP beyond the hymen on postoperative examination. 69 patients were included. Median operative time was 209 min (135-312) and estimated blood loss was 100 mL (20-2000). 1 (1.4%) patient sustained a major vascular injury resulting in laparotomy. Median pain score and morphine equivalents administered in PACU were low at 3 (0-7) and 3.2 (0-27) respectively. At 3 months, 60 (86.9%) patients were seen either in person or via telemedicine for their follow up appointment. 59/60 (98.3%) reported no vaginal bulge symptoms and 50/51 (98.0%) had stage 0 or 1 prolapse on exam. One (1.4%) patient had recurrent prolapse and underwent an additional repair. Postoperative complications included 2 (2.9%) cases of ileus/small bowel obstruction, 1 (1.4%) pelvic hematoma requiring a blood transfusion, and 1 (1.4%) umbilical hernia. The SP robotic platform is a safe and feasible platform for MIS hysterectomy and sacrocolpopexy with good short term anatomic and symptomatic outcomes.

BACKGROUND: Transanal surgery facilitates organ preservation in select patients with benign and early malignant rectal lesions to avoid the functional consequences of radical surgery. The transanal endoscopic microsurgery (TEM) platform created a standard for local excision with lower margin positivity and recurrence rates than traditional transanal excision. The single-port robot (SP r) presents a promising alternative transanal platform. The goal of this study was to compare perioperative and pathologic outcomes of TEM and SP r for excision of rectal lesions. METHODS: A review of consecutive patients who underwent local excision of rectal lesions at a tertiary referral center from 1/2001 to 5/2022 was performed. Cases were stratified into TEM or SP rTAMIS in a 1:1 propensity score-matched cohort, adjusting for all baseline characteristics. Clinical, tumor-specific, and perioperative outcomes were compared using χ2, and Mann-Whitney U-tests. The main outcomes were oncologic quality measures, complications, and operative time. RESULTS: Matching resulted 50 patients in each cohort. Groups had similar age, gender, body mass index, comorbidity, diagnosis, lesion characteristics, and neoadjuvant chemoradiation rates. There were no intraoperative complications in either cohort. Three SP rTAMIS cases were converted intraoperatively; there were no conversions in TEM. SP rTAMIS had significantly shorter operative times than TEM (mean 104 vs. 245, p = 0.027). The rates of positive distal margins (2% TEM, 0% SP rTAMIS) and piecemeal resection (4% TEM, 0% SP rTAMIS) were similar. SP rTAMIS had significantly lower postoperative morbidity rates than TEM (9% vs. 20%, p = 0.031). There was no mortality in either cohort. CONCLUSIONS: SP robotics provided high-quality outcomes similar to TEM for local excision of rectal lesions. SP robotics had faster operative time with comparable clinical and oncologic outcomes to TEM. These early data are promising for expanding use of SP robotic platforms.

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.

BACKGROUND: Endoluminal surgery is increasingly recognized as a mode of treatment for colorectal neoplasms with the latest robotic single port platform Da Vinci-SP (Intuitive Surgical, Sunnyvale) facilitating submucosal dissection of benign rectal neoplasm. METHOD: In this study, we present our initial experience with endorobotic submucosal dissection in the management of benign rectal neoplasms using the Da Vinci-SP (Intuitive Surgical, Sunnyvale) between 2020 and 2021. The primary endpoint was the successful completion of submucosal dissection. RESULTS: During the study period, 10 patients underwent endorobotic submucosal dissection for benign rectal neoplasms. The median age of the patients was 68 (range: 59-78) years, and the mean BMI was 29.38 (range: 22.9-38.5). The mean size of the lesion was 42.3 mm (range: 20-65 mm) and was located 7.3 cm (mean) from the anal verge (range: 2-10 cm). The mean operative time was 91.3 minutes (range: 57-137 minutes). All 10 dissections were completed successfully en bloc. There were no intraoperative complications or mortality. All patients were discharged on the same day and commenced on a normal diet. Late bleeding was observed in one patient receiving anticoagulation, and one patient had urinary retention. Pathology revealed two adenocarcinomas, six tubulovillous adenomas, one tubular adenoma, and one sessile serrated adenoma. There was no recurrence in all other patients during the median follow-up of 6 months (range: 4-16 months). CONCLUSIONS: Endorobotic submucosal dissection using a single-port robotic platform is safe and feasible for benign rectal mucosal neoplasms. The semiflexible platform offers an alternative to endoscopic submucosal dissection with favourable outcomes.

Pancreatic tumor enucleation is a procedure that can preserve pancreatic function and is sometimes performed using a minimally invasive approach. Recently, a single-port robotic platform called da Vinci SP has been developed. However, the technical details of pancreatic tumor enucleation using da Vinci SP have not been reported to date. We report a male patient in his 70s who underwent robotic SP pancreatic tumor enucleation for a pancreatic neuroendocrine tumor. The dissection between the tumor and pancreatic parenchyma was performed using the double bipolar technique. The operative time was 139 min, and the estimated blood loss was 4 mL. The patient had an uneventful recovery and was discharged on the sixth day after the surgery. Robotic SP pancreatic tumor enucleation appears to be a feasible procedure with lower invasiveness and better cosmesis.

AIM: Slow laparoscopy adoption accelerated the uptake of robotic surgery. However, the current robotic platforms have limitations in transanal applications and multiple port sites. The da Vinci single-port (SP) robot is currently used on trial for colorectal surgery, and broad assessment of outcomes is needed. We aimed to report findings of a phase II clinical trial of SP robotic colorectal surgery. METHODS: A sequentially reported prospective case series was performed on patients using SP robotics at a tertiary referral centre from 1 October 2018 to 31 August 2021. Cases were stratified into abdominal and transanal cohorts. Demographics, intra-operative variables and 30-day postoperative outcomes were evaluated. Univariate analysis was performed, with statistical process control for the docking process. Main outcomes were conversion rates, morbidity, mortality and point of standardization of docking. RESULTS: In all, 133 patients were included: 93 (69.92%) abdominal and 40 (30.08%) transanal. The main diagnosis was rectal cancer (n = 59) and the procedure performed a robotic transanal abdominal transanal radical proctosigmoidectomy (n = 30). There were no conversions to open surgery. Two abdominal (2.15%) and three transanal cases (7.50%) were converted to laparoscopy. All colorectal adenocarcinomas had negative margins, proper lymph node harvest and complete mesorectal excision, as appropriate. Docking became a standardized process at cases 34 (abdominal) and 23 (anorectal). After surgery, bowel function returned on mean day 2 (abdominal) and 1 (transanal). The morbidity rate was 15.05% (abdominal) and 27.50% (transanal). There were two major morbidities in each cohort. Overall, there were three (2.65%) readmissions, one reoperation and no mortality. CONCLUSIONS: Single-port robotics is feasible for all types of colorectal procedures, with good clinical and oncological outcomes. With this development in colorectal surgery, further studies can develop best practices with this novel technology.

Purpose: The da Vinci single-port (SP) system has been used in various surgical fields, including colorectal surgery. However, limited experience has been reported on its safety and feasibility. This study aims to evaluate the short-term outcomes of SP robotic surgery for the treatment of rectal cancer compared with multiport (MP) robotic surgery. Methods: Rectal cancer patients who underwent curative resection in 2020 were reviewed. A total of 43 patients underwent robotic total mesorectal excision (TME), of which 26 (13 in each group, SPTME vs. MPTME) were included in the case-matched cohort for analysis. Intraoperative and postoperative outcomes and pathological results were compared between the 2 groups. Results: Median tumor height was similar between the 2 groups (SPTME vs. MPTME: 5.9 cm [range, 2.2-9.6 cm] vs. 6.7 cm [range, 3.4-10.0 cm], P = 0.578). Preoperative chemoradiotherapy was equally performed (38.5%). The median estimated blood loss was less (20.0 mL [range, 5.0-20.0 mL] vs. 30.0 mL [range, 20.0-30.0 mL], P = 0.020) and the median hospital stay was shorter (7 days [range, 6-8 days] vs. 8 days [range, 7-9 days], P = 0.055) in the SPTME group. Postoperative complications did not differ (SPTME vs. MPTME: 7.7% vs. 23.1%, P = 0.587). One patient in the SPTME group and 3 in the MPTME group experienced anastomotic leakage. Conclusion: SP robotic TME showed perioperative outcomes similar to MP robotic TME. The SP robotic system can be considered a surgical option for the treatment of rectal cancer. Further prospective randomized trials with larger cohorts are required.
ABSTRACT
PURPOSE: The aim of the present report wasto describe a novel technique of robotic abdominoperineal resection (APR) for the treatment of T4b low rectal cancer using the da Vinci® Single-Port (SP) system (Intuitive Surgical, Sunnyvale, CA, USA). METHODS: A 3-cm transverse incision was made in the left lower quadrant of the abdomen, in the area designated for permanent colostomy. A Uniport® (Dalim Medical, Seoul, Korea) was introduced and a 25 mm multichannel SP trocar was inserted into the Uniport. A 5-mm laparoscopic assistant port was introduced on the upper midline. A video showing each step of the technique is attached. RESULTS: Two consecutive female patients (70 and 74 years old) underwent SP robotic APR with partial resection of the vagina 8 weeks after preoperative chemoradiotherapy. In both cases, rectal cancer was located 1 cm above the anal verge and invaded the vagina (initial stage and ymrT stage T4b). Operative time was 150 and 180 min, respectively. Estimated blood loss was 10 and 25 ml, respectively. No postoperative complications occurred. The length of postoperative hospital stay was 5 days in both cases. The final pathological stage was ypT4bN0 and ypT3N0 respectively. CONCLUSIONS: In this first experience, SP robotic APR appears to be a safe and feasible procedure for locally advanced low rectal cancer. In addition, the invasiveness of the procedure is reduced by means of the SP system, which only requires a single incision in the area designated for colostomy. Prospective studies on a larger number of patients are necessary to confirm the outcomes of this technique compared to other minimally invasive approaches.
ABSTRACT
BACKGROUND: The aim of this study is to compare the surgical outcomes of single-port laparoscopic surgery (SPLS) and single-port robotic surgery (SPRS). METHODS: We retrospectively analyzed patients who underwent a hysterectomy, ovarian cystectomy, or myomectomy with SPLS or SPRS from January 2020 to July 2022. Statistical analyses were performed using the SPSS chi-square test and student's t-test. RESULTS: A total of 566 surgeries including single-port laparoscopic hysterectomy (SPLH; n = 148), single-port robotic hysterectomy (SPRH; n = 35), single-port laparoscopic ovarian cystectomy (SPLC; n = 207), single-port robotic ovarian cystectomy (SPRC; n = 108), single-port laparoscopic myomectomy (SPLM; n = 12), and single-port robotic myomectomy (SPRM; n = 56). The SPRH, SPRC, and SPRM groups had a shorter operation time than the SPLS group, although the results were not statistically significant (SPRH vs. SPLH, p = 0.134; SPRC vs. SPLC, p = 0.098; SPRM vs. SPLM, p = 0.202). Incisional hernia occurred as a postoperative complication in two patients only in the SPLH group. Postoperative Hb changes were lower in the SPRC and SPRM groups than in the SPLC and SPLM groups (SPRC vs. SPLC, p = 0.023; SPRM vs. SPLM, p = 0.010). CONCLUSIONS: Our study demonstrated that the SPRS had comparable surgical outcomes when compared to the SPLS. Therefore, the SPRS should be considered a feasible and safe option for gynecologic patients.
ABSTRACT
Purpose: Studies of single-port robot-assisted thoracic surgery (RATS) using the da Vinci SP system, which uses a smaller surgical incision than the conventional multiport robot, have yet to be reported because of its smaller operating range. We report our initial experience using the da Vinci SP system in thoracic surgery for the resection of mediastinal tumors that requires a smaller workspace. Description: Two patients diagnosed with superior mediastinal tumors underwent RATS performed with the da Vinci SP surgical system in January 2022. We used three-dimensional reconstruction to preoperatively determine the surgical incision. This is the first report of single-port RATS using the SP system in China. Evaluation: R0 resection was achieved in both operations without complications. Operation times and bleeding volumes were similar to the use of multiport RATS. No perioperative complications occurred. Conclusions: The da Vinci SP system can be used for the resection of superior mediastinal tumors. Case selection and preoperative planning should be performed prior to these surgeries.
ABSTRACT
INTRODUCTION: To date, no anti-reflux operations have been reported with the new da Vinci Single-Port (single port (SP)) robotic platform. We aimed to describe this novel surgical approach and evaluate its safety and feasibility. METHODS: All robotic SP operations were performed under an Institutional Review Board approved protocol. RESULTS: Two patients underwent robotic SP anti-reflux surgery through a single incision of 2.7 cm (one Nissen-fundoplication and one re-Redo Nissen-fundoplication). The mean docking-time was 2.5 (2-3) minutes and mean console-time was 147 (119-155) minutes. No additional ports were needed, and no intraoperative complications occurred. Patients tolerated a soft diet on postoperative day 1 and were discharged on POD-2 and 3. CONCLUSION: Robotic SP anti-reflux surgery appears to be safe and feasible. This platform offers similar advantages to the multiport robotic surgery, while adding lower invasiveness and an improved cosmesis. Further studies are needed to confirm our results and evaluate long-term outcomes of this surgical approach.

BACKGROUND: We developed a novel suprapubic single-port robotic right hemicolectomy (spRHC) procedure for patients with right colon cancer using a da Vinci SP Surgical System. The aim of this study was to determine the safety and feasibility of this technique. METHODS: We performed the spRHC procedure on five patients with right colon cancers between July and September 2020. All procedures including colon mobilization, D3 lymphadenectomy, and intracorporeal anastomosis were completed using the single-port robotic platform through a mini-transverse suprapubic incision and an additional assistant port. Data regarding patient characteristics, perioperative outcomes and pathologic results were analyzed. RESULTS: Four of the five patients were males. The median age was 69 years (range, 58-77 years).Two patients received preoperative chemotherapy for advanced colon cancer. The median total operative time was 160 min (range, 150-240 min). The median docking time was 4 min 40 s (range, 2 min 10 s-5 min 10 s). The median console time was 105 min (range, 100-120 min). There were no conversions to multiport or open surgeries. The median hospital stay was 7 days (range, 5-12 days). One patient experienced a wound infection. The median number of harvested lymph nodes was 41 (range, 39-50 lymph nodes). CONCLUSIONS: SpRHC is safe and feasible. However, further comparative studies are needed to assess whether this procedure can provide patients with significant benefits compared with multiport robotic surgery.

PURPOSE: To provide a comprehensive review on the new da Vinci SP (single port) robotic surgical system. The published literature to date within urology and a description of the new system will be discussed. FINDINGS: There are currently no high-quality published studies with the SP robotic system. All studies are case series, many with 10 or fewer patients. However, all studies have found the SP system to be safe and feasible in performing most urological procedures. Renal and pelvic surgery using the SP robotic system is safe and feasible in the hands of expert robotic surgeons. Long-term, high-quality data is lacking. While the current high price and the learning curve will limit the SP systems' use in many health care systems, new updates and the release of robotic surgical systems from other developers may help drive down costs and encourage uptake.

BACKGROUND: Trans-anal excision is the surgical treatment of choice for endoscopically unresectable rectal polyps, early rectal cancers, small carcinoid tumors, and other low-risk tumors. The single-port robotic (SPR) platform is the newest development in robotic surgery capable of performing trans-anal minimally invasive surgery (TAMIS). In theory, the single incision design would naturally lend itself to the size limitation of the anal canal, but in practice, this method has not been tested. Herein we describe the techniques and first reports of performing TAMIS using the SPR platform. TECHNIQUE: We describe in detail how to perform the SPR-TAMIS technique using lessons and experience gained from performing this on five patients who had endoscopically unresectable rectal polyps or T1 rectal cancers. Each patient was followed for a minimum of 30 days and was seen in clinic post-operatively. A retrospective chart review was performed to obtain information on technical success, anatomic measurements, and reported complications. RESULTS: The SPR TAMIS was successfully performed on all five patients without any reported complications. All underwent a non-piecemeal excision and had return of regular bowel function at 30-day follow-up. All patients were discharged from the hospital the same day as their operation. CONCLUSIONS: SPR-TAMIS is a novel, safe, and feasible procedure capable of achieving non-piecemeal resections of low-risk rectal tumors. Further study needs to be conducted to determine complication rates, functional and oncologic outcomes, and ensure the long-term safety profile.

In compliance with the trend toward less invasive techniques, single incision robotic surgeries have become more common and they have been increasingly used for several surgeries including adrenalectomy. Single incision robotic adrenalectomy (SIRA) aims to combine the merits of robotic surgery with previously defined single incision laparoscopic techniques. It has been shown to be safe and feasible, however, there are only few studies on this new technique. Due to scant data on SIRA in the current literature, it remains to be a current challenge in adrenal surgery. In this review, our goal is to present current literature on SIRA and discuss the data regarding perioperative outcomes, patient selection, learning curve, and its limitations.
ABSTRACT
Urologists have always been leaders in advancing surgical technology and were the first to utilize modern robotic surgery for robotic-assisted laparoscopic radical proctectomy. Surgeon ergonomics, instrument precision, operative time, and postoperative recovery were all objectively improved. In urology, robotic surgery is now used for all intra-abdominal, retroperitoneal, and pelvic procedures and has been expanded to renal transplants and pediatric use. Modern robotic surgery has become an essential part of treating complex urologic disease in the developed world. Urologists continue to lead the way with the latest robotic surgical systems, including the newly approved single port systems.
