Project description:ObjectiveTo assess the feasibility of single-port transperitoneal robotic-assisted laparoscopic radical prostatectomy (spRALP) and discuss its surgical technique.MethodsA 60-year-old male was admitted with an elevated prostate-specific antigen (PSA) level of 13.89 ng/mL and confirmed with prostate cancer on biopsy showing three of 22 positive cores with a Gleason score of 3 + 4 = 7. Multiparametric magnetic resonance (MR) and bone scintigraphy showed organ-confined disease. spRALP was performed using da Vinci Si HD surgical system, with access of a quadri-channel laparoscopic port placed supraumbilically. Two drainage tubes were placed before wound closure. The surgical procedure was largely in consistence with a conventional robotic-assisted laparoscopic radical prostatectomy.ResultsThe surgery was successfully carried out with a duration of 152 min and an estimated blood loss of 100 mL. The patient was discharged on postoperative Day 4 after removal of both pelvic drainage tubes. Foley catheter was removed on postoperative Day 14. No major complications were encountered. Postoperative pathology showed a Gleason score of 3 + 4 = 7 with no extraprostatic extension and negative surgical margins.ConclusionSingle-port robotic prostatectomy is feasible using the currently available robotic instruments in most Chinese robotic urological centers. Meticulous preoperative planning and careful patient selection are mandatory. Further studies concerning perioperative complications and pentafecta outcome compared with the conventional multi-port robotic prostatectomy is required.

Project description:BackgroundThis study presents the procedure of single-port extraperitoneal transvesical approach to robot-assisted radical prostatectomy (SETvRARP) on the da Vinci Xi platform coupling with a 4-channel single port and evaluated the short-term outcomes in the first 72 prostate cancer (PCa) patients.MethodsSeventy-two patients with localized PCa were enrolled. Each operation was conducted by the same single robotic surgery group in two centers using the da Vinci Xi system.ResultsThe median operation time was 150 min, and the median estimated blood loss was 50 mL. All operations were successfully carried out without open conversion or transfusion. No ≥ Grade II complications were noted. Urethral catheters were routinely removed on postoperative day 7. Sixty-eight (94.4%) patients recovered to immediate urinary continence after surgery, with 72 (100%) patients achieving full continence on postoperative day 14. A positive surgical margin was observed in 15 (20.8%) patients. Postoperative urodynamic studies regarding peak urinary flow, bladder capacity, and residual urine were not statically different from the preoperative results. No biochemical recurrence was noted in all patients within the follow-up period. Postoperative erectile function was not statistically different from the preoperative results (P=0.1697).ConclusionsSETvRARP using the da Vinci Xi system coupling with a 4-channel single port is a valid radical prostatectomy technique in well-selected PCa patients, resulting in superior postoperative recovery of urinary continence. Meanwhile, the outcomes in functional protection and cancer control need to be further investigated with a long-term follow-up duration.

Project description:Objective The limitations of tissue retraction and the amount of surgical working space have a great impact on extraperitoneal single-port robotic-assisted radical prostatectomy (sp-RARP) with the multiport robotic surgical system. We used an extraperitoneal tissue retraction technique to achieve tissue exposure and working space expansion. This study evaluated the safety, feasibility, and efficacy of the extraperitoneal tissue retraction technique in extraperitoneal pure sp-RARP with the da Vinci Si surgical system. Methods Data from 42 patients were analyzed retrospectively from December 2018 to February 2020. The extraperitoneal tissue retraction technique was not used in 20 patients (group I) and was used in 22 patients (group II). Preoperative, intraoperative, and postoperative data were collected. The oncological and functional data during late follow-up were recorded. Results All patients successfully underwent extraperitoneal pure sp-RARP. No patients required conversion to a multiport surgery or placement of additional assistant ports. The two groups were similar regarding baseline features. The median operation time in group I was significantly longer than that in group II (P < 0.001). The estimated blood loss volume in group I was significantly higher than that in group II (P < 0.001). There were no serious complications in either group. There were four cases of peritoneal tears in group I and none in group II (P = 0.043). The surgical margin and lymph nodes were negative in both groups. The oncological and functional outcomes were similar between the two groups 6 months after the procedure. Conclusions The extraperitoneal tissue retraction technique is safe and feasible. The technique promotes tissue exposure and expands the surgical working space, which is important for achieving extraperitoneal pure sp-RARP with the da Vinci Si surgical system, especially for beginners. The short-term oncological and functional outcomes were within acceptable ranges. The long-term effects of this technique need further evaluation.

Project description: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.

Project description:Background and objectiveThe role of pelvic lymph node dissection (PLND) for prostate cancer is still controversial. This study aims to compare the outcomes of PLND between extraperitoneal single-port (SP eRARP) and transperitoneal multiport (MP tRARP) robotic-assisted radical prostatectomy.MethodsThis was a retrospective analysis from our single-center database for patients who underwent SP eRARP or MP tRARP with PLND between 2015 and 2023. The primary endpoint was to analyze and compare specific data related to PLND between the two populations by the detection of pN+ patients, the total number of lymph nodes removed, and the number of positive lymph nodes removed. The secondary endpoints included comparing major complications, lymphoceles, and biochemical recurrence between the two cohorts of the study.Key findings and limitationsA total of 293 patients were included, with 85 (29%) undergoing SP eRARP and 208 (71%) undergoing MP tRARP. SP eRARP showed significant differences in PLND extension from MP tRARP, while MP tRARP yielded more lymph nodes (p < 0.001). There were no differences in pN+ patient detection (p = 0.7) or the number of positive lymph nodes retrieved (p = 0.6). The rates of major complications (p = 0.6), lymphoceles (p = 0.2), and biochemical recurrence (p = 0.9) were similar between the two groups. Additionally, SP eRARP had shorter operative time (p = 0.045), hospital stay (p < 0.001), and less postoperative pain at discharge (p = 0.03). Limitations include a retrospective, single-center analysis.Conclusions and clinical implicationsDespite the SP approach in RARP resulting in fewer retrieved lymph nodes, outcomes were comparable with the MP approach regarding the detection of patients with positive lymph nodes and the number of positive nodes. Additionally, the SP approach led to lower pain levels and shorter hospital stays.Patient summaryWith this study, we demonstrate that pelvic lymph node dissection performed via the extraperitoneal approach during robotic-assisted radical prostatectomy with a single-port system provides comparable outcomes with the standard transperitoneal multiport approach in detecting patients with positive lymph nodes and retrieving positive nodes. In addition, it offers significantly reduced pain levels and shorter hospital stays.

Project description:PurposeTo report an initial single-surgeon experience with single-port robot-assisted radical prostatectomy (SP-RARP) using the da Vinci SP surgical system (Intuitive Surgical, USA).Materials and methodsBetween December 2018 and October 2019, a single surgeon performed SP-RARP in 20 patients with prostate cancer. SP-RARP was performed using the conventional approach through an umbilical port with a GelPOINT access system (Applied Medical, USA) and an additional assist port. During surgery, the camera was placed in the 6- or 12-o'clock position, and a traction arm was placed in the counterpart position for upward or downward traction. Clinicopathologic data, perioperative data, and short-term surgical outcomes were analyzed.ResultsOf 20 patients, 45% of patients had pT3 or greater disease and 45% had Gleason grade 4 to 5, respectively. In 11 patients that underwent lymph node dissection, the median number of lymph nodes removed was 19 (interquartile range [IQR], 14-22). Median operative time was 245 minutes (IQR, 200-255), and median console time was 190 minutes (IQR, 165-210). Median blood loss was 200 mL (IQR, 150-300 mL), and there were no intraoperative complications or open conversion. In 10 patients with a follow-up period longer than 3 months, one patient experienced biochemical recurrence, and all patients required 0 to 1 pads per day. Of seven patients that were potent before surgery, four recovered erectile function sufficient for intercourse.ConclusionsOur report shows the safety and feasibility of SP-RARP, and that the associated surgical outcomes with short-term follow-up are satisfactory.

Project description: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.
