[Robotic-Assisted DIEP Flap Harvest for Autologous Breast Reconstruction: Case Report, Technical Aspects and Identification of Suitable Patients]. / Die robotisch-assistierte Hebung der DIEP-Lappenplastik zur Brustrekonstruktion: Fallbericht, technische Aspekte und Identifikation geeigneter Patientinnen.

BACKGROUND: Robotic-assisted harvest of the deep inferior epigastric perforator (DIEP) flap is an innovative modification of the traditional open preparation for autologous breast reconstruction. It is assumed that donor-site morbidity (herniae, bulging) is reduced by minimising the fascial incision length in robotic-assisted DIEP flap harvest. MATERIAL & METHODS: This is the first report of a robotic-assisted DIEP harvest in Germany, which was performed in April 2023 at the University Hospital of Freiburg in an interdisciplinary approach of the Departments of Plastic Surgery, Urology and Gynaecology. To determine the value of this novel technique, we assessed the demand by retrospectively performing an analysis of potential patients and conducted a cost analysis based on the breast reconstructions with DIEP flap harvest performed between April 2021 and May 2023 at the Department of Plastic Surgery at Freiburg University Hospital. To this end, we carried out a retrospective analysis of preoperative CT angiographies to determine the proportion of patients suitable for a robotic-assisted procedure in a post-hoc analysis. Furthermore, we describe the basic robotic-assisted techniques and discuss the TEP and TAPP laparoscopic approaches. RESULTS: In line with the previously published literature, a short intramuscular course (≤25 mm) and a perforator diameter of≥1.5 mm and≥2.7 mm (subgroup) were defined as a crucial condition for the robotic-assisted procedure. We analysed 65 DIEP flaps harvested in 51 patients, of which 26 DIEP flaps in 22 patients met both criteria, i. e.≤25 mm intramuscular course and≥1.5 mm diameter of the perforator, while 10 DIEP flaps in 10 patients additionally met the criteria of the subgroup (≥2.7 mm diameter). Based on the intramuscular course of the perforators in the CT angiographies of those 26 DIEP flaps, a potential reduction of the fascial incision of 96.8±25.21 mm (mean±standard deviation) compared with the conventional surgical approach was calculated. The additional material costs in our case were EUR 986.01. However, ischaemia time was 33,5 minutes longer than the median of the comparative cohort. CONCLUSION: The robotic-assisted procedure has already proven to be a feasible alternative in a suitable patient population. However, further studies are needed to confirm that robotic-assisted DIEP flap harvest actually reduces harvest site morbidity and thereby justifies the additional costs and complexity.

Current practice and unmet training needs in robotic-assisted radical prostatectomy: investigation from the Junior ERUS/YAU working group.

PURPOSE: To access the current scenario of robotic-assisted radical prostatectomy training in multiple centers worldwide. METHODS: We created a multiple-choice questionnaire assessing all details of robotic-assisted radical prostatectomy training with 41 questions divided into three different categories (responder demography, surgical steps, and responder experience). The questionnaire was created and disseminated using the "Google Docs" platform. All responders had an individual invitation by direct message or Email. We selected urologists who had recently finished a postgraduation urologic robotic surgery training (fellowship) in the last five years. We sent 624 invitations to urologists from 138 centers, from January 10th to April 10th, 2022. The answers were reported as percentages and illustrated in pie charts. RESULTS: The response rate was 58% among all centers invited (138/81), 20% among all individual invitations (122/624 answers). Globally, we gathered responses from 23 countries. Most surgeons were older than 34 years, 71% trained in an academic center, and 64% performed less than ten full RARP cases. Transperitoneal is the most common access, and 63% routinely opens the endopelvic fascia. Almost 90% perform the Rocco's stitch, and 94% perform the anastomosis with barbed sutures. Finally, only 31% of surgeons assisted more than 100 cases before moving to the console, and most surgeons (63.9%) performed less than ten full RARP cases during their training. CONCLUSION: By assessing the robotic-assisted radical prostatectomy training status in 23 countries and 81 centers worldwide, we assessed the trainees' demography, step-by-step surgical technique, training perspectives, and impressions of surgeons who trained in the last five years. This data is crucial for a better understanding the trainee's standpoint, addressing potential deficiencies, and implementing improvements needed in the training process. Our study clearly indicates elements of current training modalities that are prone to major improvement.

Atlas of Intracorporeal Orthotopic Neobladder Techniques After Robot-assisted Radical Cystectomy and Systematic Review of Clinical Outcomes.

BACKGROUND: Multiple and heterogeneous techniques have been described for orthotopic neobladder (ONB) reconstruction after robot-assisted radical cystectomy. Nonetheless, a systematic assessment of all the available options is lacking. OBJECTIVE: To provide the first comprehensive step-by-step description of all the available techniques for robotic intracorporeal ONB together with individual intraoperative, perioperative and functional outcomes based on a systematic review of the literature. DESIGN, SETTING, AND PARTICIPANTS: We performed a systematic review of the literature, and MEDLINE/PubMed, Embase, Scopus, and Web of Science databases were searched to identify original articles describing different robotic intracorporeal ONB techniques and reporting intra- and perioperative outcomes. Studies were categorized according to ONB type, providing a synthesis of the current evidence. Video material was provided by experts in the field to illustrate the surgical technique of each intracorporeal ONB. SURGICAL PROCEDURE: Nine different ONB types were identified: Studer, Hautmann, Y shape, U shape, Bordeaux, Pyramid, Shell, Florence Robotic Intracorporeal Neobladder, and Padua Ileal Neobladder. MEASUREMENTS: Continuous and categorical variables are presented as mean ± standard deviation and as frequencies and proportions, respectively. RESULTS AND LIMITATIONS: Of 2587 studies identified, 19 met our inclusion criteria. No cohort studies or randomized control trials comparing different neobladder types are available. Available techniques for intracorporeal robotic ONB reconstruction have similar operative time, estimated blood loss, intraoperative complications, and length of stay. Major variability exists concerning postoperative complications and functional outcomes, likely related to reporting bias. CONCLUSIONS: Several techniques are described for intracorporeal ONB during robot-assisted radical cystectomy with comparable perioperative outcomes. We provide the first step-by-step surgical atlas for robot-assisted ONB reconstruction. Further comparative studies are needed to assess any advantage of one technique over others. PATIENT SUMMARY: Patients elected for radical cystectomy should be aware that multiple techniques for robotic orthotopic neobladder are available, but that current evidence does not favor one type over the others.

Outcomes of Salvage Robotic-assisted Radical Prostatectomy in the last decade: systematic review and perspectives of referral centers

ABSTRACT Purpose: Salvage robotic-assisted radical prostatectomy (S-RARP) has gained prominence in recent years for treating patients with cancer recurrence following non-surgical treatments of Prostate Cancer. We conducted a systematic literature review to evaluate the role and outcomes of S-RARP over the past decade. Materials and Methods: A systematic review was conducted, encompassing articles published between January 1st, 2013, and June 1st, 2023, on S-RARP outcomes. Articles were screened according to PRISMA guidelines, resulting in 33 selected studies. Data were extracted, including patient demographics, operative times, complications, functional outcomes, and oncological outcomes. Results: Among 1,630 patients from 33 studies, radiotherapy was the most common primary treatment (42%). Operative times ranged from 110 to 303 minutes, with estimated blood loss between 50 to 745 mL. Intraoperative complications occurred in 0 to 9% of cases, while postoperative complications ranged from 0 to 90% (Clavien 1-5). Continence rates varied (from 0 to 100%), and potency rates ranged from 0 to 66.7%. Positive surgical margins were reported up to 65.6%, and biochemical recurrence ranged from 0 to 57%. Conclusion: Salvage robotic-assisted radical prostatectomy in patients with cancer recurrence after previous prostate cancer treatment is safe and feasible. The literature is based on retrospective studies with inherent limitations describing low rates of intraoperative complications and small blood loss. However, potency and continence rates are largely reduced compared to the primary RARP series, despite the type of the primary treatment. Better-designed studies to assess the long-term outcomes and individually specify each primary therapy impact on the salvage treatment are still needed. Future articles should be more specific and provide more details regarding the previous therapies and S-RARP surgical techniques.

Discrimination, Reliability, Sensitivity, and Specificity of Robotic Surgical Proficiency Assessment With Global Evaluative Assessment of Robotic Skills and Binary Scoring Metrics: Results From a Randomized Controlled Trial.

Objective: To compare binary metrics and Global Evaluative Assessment of Robotic Skills (GEARS) evaluations of training outcome assessments for reliability, sensitivity, and specificity. Background: GEARS-Likert-scale skills assessment are a widely accepted tool for robotic surgical training outcome evaluations. Proficiency-based progression (PBP) training is another methodology but uses binary performance metrics for evaluations. Methods: In a prospective, randomized, and blinded study, we compared conventional with PBP training for a robotic suturing, knot-tying anastomosis task. Thirty-six surgical residents from 16 Belgium residency programs were randomized. In the skills laboratory, the PBP group trained until they demonstrated a quantitatively defined proficiency benchmark. The conventional group were yoked to the same training time but without the proficiency requirement. The final trial was video recorded and assessed with binary metrics and GEARS by robotic surgeons blinded to individual, group, and residency program. Sensitivity and specificity of the two assessment methods were evaluated with area under the curve (AUC) and receiver operating characteristics (ROC) curves. Results: The PBP group made 42% fewer objectively assessed performance errors than the conventional group (P < 0.001) and scored 15% better on the GEARS assessment (P = 0.033). The mean interrater reliability for binary metrics and GEARS was 0.87 and 0.38, respectively. Binary total error metrics AUC was 97% and for GEARS 85%. With a sensitivity threshold of 0.8, false positives rates were 3% and 25% for, respectively, the binary and GEARS assessments. Conclusions: Binary metrics for scoring a robotic VUA task demonstrated better psychometric properties than the GEARS assessment.

Differences in Quality of Life between German and Dutch Patients with Prostate Cancer Treated with Robot-assisted Radical Prostatectomy: Implications for International Multicenter Randomized Controlled Trials.

BACKGROUND: As a local treatment for prostate cancer (PCa), robot-assisted radical prostatectomy (RARP) may have a quality of life (QoL) benefit over open surgery. Recent analyses revealed substantial between-country differences in the function and symptom scale scores for the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), which is typically used to assess patient-reported QoL. Such differences could have implications for multinational studies in PCa. OBJECTIVE: To examine whether nationality is significantly associated with patient-reported QoL. DESIGN, SETTING, AND PARTICIPANTS: The study cohort comprised Dutch and German patients with PCa treated with RARP in a single high-volume prostate center from 2006 to 2018. Analyses were restricted to patients who were preoperatively continent with at least one follow-up time point. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: QoL was measured in terms of the global Quality of Life (QL) scale score and the overall summary score for the EORTC QLQ-C30. Linear mixed models for repeated-measures multivariable analyses (MVAs) were used to examine the association between nationality and both the global QL score and the summary score. MVAs were further adjusted for QLQ-C30 baseline values, age, Charlson comorbidity index, preoperative prostate-specific antigen, surgical expertise, pathological tumor and nodal stage, Gleason grade, degree of nerve-sparing, surgical margin status, 30-d Clavien-Dindo grade complications, urinary continence recovery, and biochemical recurrence/postoperative radiotherapy. RESULTS AND LIMITATIONS: For Dutch (n = 1938) versus German (n = 6410) men, the mean baseline scores were 82.8 versus 71.9 for the global QL scale score and 93.4 versus 89.7 for the QLQ-C30 summary score. Urinary continence recovery (QL: +8.9, 95% confidence interval [CI] 8.1-9.8; p < 0001) and Dutch nationality (QL: +6.9, 95% CI 6.1-7.6; p < 0001) were the strongest positive contributors to the global QL and summary scores, respectively. The main limitation is the retrospective study design. In addition, our Dutch cohort may not be representative of the general Dutch population and reporting bias cannot be ruled out. CONCLUSIONS: Our findings provide observational evidence under specific conditions involving the same setting for patients of two different nationalities suggesting that cross-national patient-reported QoL differences appear to be real and may need to be taken into consideration in multinational studies. PATIENT SUMMARY: We observed differences in the quality-of-life scores reported by Dutch and German patients with prostate cancer after they underwent robot-assisted removal of the prostate. These findings should be taken into consideration in cross-national studies.

Chicken RAPS: Chicken Robot-assisted Pyeloplasty Simulation. Validation Study of a Novel Chicken Model for Wet Laboratory Training in Robot-assisted Pyeloplasty.

Background: Since the introduction of minimally invasive surgery, the number of simulation models available for teaching new surgeons has continued to increase. Objective: To evaluate and validate use of a model for teaching robot-assisted pyeloplasty. Design setting and participants: Twenty simulated robot-assisted pyeloplasty procedures were performed by experienced (n = 4) and novice (n = 16) surgeons using a chicken crop model at two different training centers using third- and fourth-generation robotic systems. Outcome measurements and statistical analysis: We evaluated the time needed to perform the procedure, and the sufficiency and patency of the anastomosis. Participants rated the efficiency, face validity, and possible acceptance of the model as part of a structured curriculum on a scale from 0 to10. Statistical significance for comparison of results was set at p < 0.05. Results and limitations: Robot-assisted pyeloplasty was successfully performed by 75% of the participants. The completion time was significantly higher in the novice group (p = 0.016). The model was deemed to be similar to the human ureteropelvic junction by the novice group. Both groups regarded the model as a useful simulation task as part of a standardized training curriculum, with mean scores of 6.5 versus 8.69 (p = 0.046) for face validity and 8 versus 9.25 for acceptance (p = 0.053) reported by the experienced versus novice group, respectively. Limitations of the study are the costs associated with the robotic system and the unequal number of participants in the groups. Conclusions: The chicken crop model is a low-cost and reproducible simulation model for accomplishing both the resection and reconstructive steps during the learning phase for robot-assisted pyeloplasty. Patient summary: We assessed the use of chickens as a model for practicing a robot-assisted operation called pyeloplasty to fix narrowing of the ureter (the tube that drains urine from the kidney to the bladder) where it attaches to the kidney. This model can be used for simulation of robot-assisted pyeloplasty when training new robotic surgeons.

Impact of Surgical Experience Before Robot-assisted Partial Nephrectomy on Surgical Outcomes: A Multicenter Analysis of 2500 Patients.

Background: Robot-assisted partial nephrectomy (RAPN) is a challenging procedure that is influenced by a multitude of factors. Objective: To assess the impact of prior surgical experience on perioperative outcomes in RAPN. Design setting and participants: In this retrospective multicenter study, results for 2548 RAPNs performed by 25 surgeons at eight robotic referral centers were analyzed. Perioperative data for all consecutive RAPNs from the start of each individual surgeon's experience were collected, as well as the number of prior open or laparoscopic kidney surgeries, pelvic surgeries (open, laparoscopic, robotic), and other robotic interventions. Intervention: Transperitoneal or retroperitoneal RAPN. Outcome measurements and statistical analysis: The impact of prior surgical experience on operative time, warm ischemia time (WIT), major complications, and margin, ischemia, complication (MIC) score (negative surgical margins, WIT ≤20 min, no major complications) was assessed via univariate and multivariable regression analyses accounting for age, gender, body mass index (BMI), American Society of Anesthesiologists score, PADUA score, and RAPN experience. Results and limitations: BMI, PADUA score, and surgical experience in RAPN had a strong impact on perioperative outcomes. A plateau effect for the learning curve was not observed. Prior laparoscopic kidney surgery significantly reduced the operative time (p < 0.001) and WIT (p < 0.001) and improved the MIC rate (p = 0.022). A greater number of prior robotic pelvic interventions decreased WIT (p = 0.011) and the rate of major complications (p < 0.001) and increased the MIC rate (p = 0.011), while prior experience in open kidney surgery did not. One limitation is the short-term follow-up. Conclusions: Mastering of RAPN is an ongoing learning process. However, prior experience in laparoscopic kidney and robot-assisted pelvic surgery seems to improve perioperative outcomes for surgeons when starting with RAPN, while experience in open surgery might not be crucial. Patient summary: In this multicenter analysis, we found that a high degree of experience in keyhole kidney surgery and robot-assisted pelvic surgery helps surgeons in achieving good initial outcomes when starting robot-assisted kidney surgery.

Staple Containing Ureteral Stone Formation After Robot-Assisted Radical Cystectomy With Intracorporeal Neobladder Construction in a Female Patient: A Case Report of a Rare Complication.

Radical cystectomy with intracorporeal neobladder formation is a well-established treatment for patients with muscle-invasive urothelial cancer of the bladder. After the wide implementation of robotic systems, numerous centers increasingly offer intracorporeal neobladder construction using robotic staple devices. Stone formation at the area of staple material migration is a long-term complication, as staple material may migrate through the neobladder wall and act as a nidus for urine crystal aggregation. Stone formation in the upper urinary tract and the diversion segment is highly variable and corresponding management protocols are extensively reported in the previous series. However, the presence of staple material within a renal or ureteral stone has been rarely reported before. We present a case of a female patient with a staple-containing ureteral stone four years after radical cystectomy and neobladder formation and the consequent antegrade ureterorenoscopic retrieval. This treatment option is feasible, safe and easily implemented by experienced endourologists.

Reporting and grading of complications for intracorporeal robot-assisted radical cystectomy: an in-depth short-term morbidity assessment using the novel Comprehensive Complication Index®.

OBJECTIVE: To assess suitability of Comprehensive Complication Index (CCI®) vs. Clavien-Dindo classification (CDC) to capture 30-day morbidity after robot-assisted radical cystectomy (RARC). MATERIALS AND METHODS: A total of 128 patients with bladder cancer (BCa) undergoing intracorporeal RARC with pelvic lymph node dissection between 2015 and 2021 were included in a retrospective bi-institutional study, which adhered to standardized reporting criteria. Thirty-day complications were captured according to a procedure-specific catalog. Each complication was graded by the CDC and the CCI®. Multivariable linear regression (MVA) was used to identify predictors of higher morbidity. RESULTS: 381 complications were identified in 118 patients (92%). 55 (43%), 43 (34%), and 20 (16%) suffered from CDC grade I-II, IIIa, and ≥ IIIb complications, respectively. 16 (13%), 27 (21%), and 2 patients (1.6%) were reoperated, readmitted, and died within 30 days, respectively. 31 patients (24%) were upgraded to most severe complication (CCI® ≥ 33.7) when calculating morbidity burden compared to corresponding CDC grade accounting only for the highest complication. In MVA, only age was a positive estimate (0.44; 95% CI = 0.03-0.86; p = 0.04) for increased cumulative morbidity. CONCLUSION: The CCI® estimates of 30-day morbidity after RARC were substantially higher compared to CDC alone. These measurements are a prerequisite to tailor patient counseling regarding surgical approach, urinary diversion, and comparability of results between institutions.

Impact of obesity on perioperative, functional and oncological outcomes after robotic-assisted radical prostatectomy in a high-volume center.

OBJECTIVE: To compare surgical, oncological and functional outcomes between obese vs. normal-weight prostate cancer (PCa) patients treated with robotic-assisted radical prostatectomy (RARP). MATERIALS AND METHODS: We assessed 4555 consecutive RARP patients from a high-volume center 2008-2018. Analyses were restricted to normal-weight vs. obese patients (≥ 30 kg/m2). Multivariable cox regression analyses (MVA) assessed the effect of obesity on biochemical recurrence (BCR), metastatic progression (MP), erectile function and urinary continence recovery. Analyses were repeated after propensity score matching. RESULTS: Before matching, higher rates of pathological Gleason Grade group ≥ 4 (14 vs. 18%; p = 0.004) and pT3 stage (33 vs. 35%; p = 0.016) were observed in obese patients, with similar observations for surgery time, blood loss and 30-day wound- and surgical complication rates. For normal-weight vs. obese patients, BCR- and MP-free rates were 86 vs. 85% (p = 0.97) and 97.5 vs.97.8% (p = 0.8) at 48 months. Similarly, rates of erectile function at 36 months and urinary continence at 12 months were 56 vs. 49% (p = 0.012) and 88 vs. 85% (p = 0.003), respectively. Before and after propensity score matching, obesity had no effect on BCR or MP, but a negative effect on erectile function (matched HR 0.87, 95%CI 0.76-0.99; p = 0.029) and urinary continence recovery (matched HR 0.91, 95%CI 0.84-0.98; p = 0.014). CONCLUSIONS: Obesity did not represent a risk factor of BCR or MP after RARP despite higher rates of adverse pathological features. However, obesity was associated with higher risk of perioperative morbidity and impaired functional outcomes. Such information is integral for patient counselling. Thus, weight loss before RARP should be encouraged.

The Dilemma of Misclassification Rates in Senior Patients With Prostate Cancer, Who Were Treated With Robot-Assisted Radical Prostatectomy: Implications for Patient Counseling and Diagnostics.

OBJECTIVES: There is a recent paradigm shift to extend robot-assisted radical prostatectomy (RARP) to very senior prostate cancer (PCa) patients based on biological fitness, comorbidities, and clinical PCa assessment that approximates the true risk of progression. Thus, we aimed to assess misclassification rates between clinical vs. pathological PCa burden. MATERIALS AND METHODS: We compared senior patients with PCa ≥75 y (n = 847), who were propensity score matched with younger patients <75 y (n = 3,388) in a 1:4 ratio. Matching was based on the number of biopsy cores, prostate volume, and preoperative Cancer of the Prostate Risk Assessment (CAPRA) risk groups score. Multivariable logistic regression models (LRMs) predicted surgical CAPRA (CAPRA-S) upgrade, which was defined as a higher risk of the CAPRA-S in the presence of lower-risk preoperative CAPRA score. LRM incorporated the same variables as propensity score matching. Moreover, patients were categorized as low-, intermediate-, and high-risk, preoperative and according to their CAPRA and CAPRA-S scores. RESULTS: Surgical CAPRA risk strata significantly differed between the groups. Greater proportions of unfavorable intermediate risk (39 vs. 32%) or high risk (30 vs. 28%; p < 0.001) were observed. These proportions are driven by greater proportions of International Society of Urological Pathology (ISUP) Gleason Grade Group 4 or 5 (33 vs. 26%; p = 0.001) and pathological tumor stage (≥T3a 54 vs. 45%; p < 0.001). Increasing age was identified as an independent predictor of CAPRA-S-based upgrade (age odds ratio [OR] 1.028 95% CI 1.02-1.037; p < 0.001). CONCLUSION: Approximately every second senior patient has a misclassification in (i.e., any up or downgrade) and each 4.5th senior patient specifically has an upgrade in his final pathology that directly translates to an unfavorable PCa prognosis. It is imperative to take such substantial misclassification rates into account for this sensitive PCa demographic of senior men. Future prospective studies are warranted to further optimize PCa workflow and diagnostics, such as to incorporate modern imaging, molecular profiling and implement these into biopsy strategies to identify true PCa burden.

Oncologic impact of concomitant prostate cancer characteristics at the time of radical cystoprostatectomy for bladder cancer: a population-based analysis.

OBJECTIVE: The aim of this study was to evaluate the prognostic impact of concomitant prostate cancer (PCa) of the cancer-specific mortality (CSM) in the aging patient's papulation with bladder cancer (BCa) treated with radical cystoprostatectomy (RCP). MATERIALS AND METHODS: Within the SEER database (2004-2015), 1468 patients were treated with RCP for BCa harboring histopathological PCa findings. To account for other cause mortality (OCM), multivariable competing risk regression (CRR) tested for potential BCa-CSM differences according to PCa characteristics risk factors predicting CSM. RESULTS: CRR analysis revealed that only following BCa characteristics, as high pathological tumor stages(Ta/Tis/T1 [REF.] vs. T2; HR 2.03, 95% CI: 1.16-3.57, p = 0.014 vs. T3; HR 4.32, 95% CI: 2.45-7.61, p < 0.001 vs. T4; HR 5.06, 95% CI: 2.77-9.22, p < 0.001), as well unfavorable BCa grade IV (Grade I-II [REF.] vs. Grade IV; HR 0.58, 95% CI: 0.35-0.98, p < 0.041) achieved independent predictor status of CSM. With regard to PCa characteristics, none of the covariates yielded independent predictor status of CSM. CONCLUSIONS: Our study, based on the largest population cohort, demonstrates that even in organ-confined BCa patients, concomitant PCa as second malignancy does not represent a risk factor for survival.

Two-year quality of life after robot-assisted radical prostatectomy according to pentafecta criteria and cancer of the prostate risk assessment (CAPRA-S).

The quality of life (QoL) of men with optimal outcomes after robot-assisted radical prostatectomy (RARP) is largely unexplored. Thus we assessed meaningful changes of QoL measured with the EORTC QLQ-C30 24 months after RARP according to postsurgical Cancer of the Prostate Risk Assessment score (CAPRA-S) and pentafecta criteria. 2871 prostate cancer (PCa) patients with completed EORTC QLQ-C30 were stratified according to CAPRA-S, pentafecta (erectile function recovery, urinary continence recovery, biochemical-recurrence-free survival (BFS), negative surgical margins) and 90-day Clavien-Dindo-complications (CDC) ≤ 3a. Multivariable logistic regression analyses (LRM) aimed to predict improvement of EORTC QoL. Mean preoperative QoL values did not significantly differ between CAPRA-S low- (LR) vs. high-risk (HR, 75.7 vs. 75.2; p = 0.7) and pentafecta vs. non-pentafecta groups (75.6 vs. 75.2; p = 0.6). After RARP, stable QoL rates for CAPRA-S LR vs. HR and pentafecta were 30, 26 and 30%, respectively. Corresponding improved QoL rates were 44, 32 and 47%. In LRM, CAPRA-S and pentafecta criteria were independent predictors of improved QoL. We conclude that most favourable combined outcomes after RARP might confer stable or even improved QoL but up to one third of patients might experience deterioration. This warrants further investigation how to capture the underlying cause and to address and potentially solve these perceived negative effects despite successful RARP.

Potential for optimizing the perioperative care in robotic prostatectomy patients by adoption of enhanced recovery after surgery principles.

Several benefits have been reported after applying the principles of enhanced recovery after surgery (ERAS) into the perioperative care of patients undergoing robot-assisted radical prostatectomy (RARP). Nevertheless, there are still barriers. We aimed to identify the key areas by systematically surveying urology departments in Germany and Austria. A 27-question survey on the adoption of ERAS principles for the perioperative care of RARP patients was designed, in compliance with the guidelines on good practice in conducting and reporting of survey research. After positive testing for face and content validity, the survey was distributed via postal mail to 82 departments performing RARP. In total, 39 departments responded to our survey (response rate 48%). The ERAS adoption rates ranged from 21 to 97%, with nine ERAS principles being widely adopted (72-92% of the departments). The lowest adoption rates and, subsequently, the largest potential for optimization were detected for the preoperative nutrition counselling (21%), preoperative pelvic floor physiotherapy (54%), postoperative early initiation of nutrition (44%) and postoperative patient audit for further quality improvement (36%). High-volume centers performed more frequently a perioperative nutrition counselling (8/27; 30%) than low-volume centers (0/12; 0%; p = 0.036). The implementation of the ERAS principles into the perioperative care algorithm were medium-to-high, yet not optimal. Our real-world data assessment revealed four key areas showing low adoption rates (nutrition counselling, preoperative pelvic floor physiotherapy, early initiation of nutrition and patient audit), implying a great potential for further optimization.
