The impact of atrial fibrillation on outcomes in patients undergoing radical prostatectomy.

To assess the role of atrial fibrillation (AF) on complicating inpatient outcomes of radical prostatectomy (RP). We identified patients treated with RP during 2012-2014 within National Inpatient Sample (NIS) database. Length of stay, cost of hospitalization, and in-hospital complications were compared between patients with or without diagnosis of AF. Propensity score matching methods and multivariable regression analysis were used to adjust for potential confounders and a trend analysis was conducted. Patients with AF had a significantly longer hospital stay (coefficient 0.19, 95% CI 0.09-0.29, P < 0.001) and higher cost (coefficient 0.10, 95% CI 0.06-0.15, P < 0.001). Post-operative cardiac complications were significantly higher for patients with AF (OR 16.38, 95% CI 7.72-34.74, P < 0.001), while no differences were found in other complications between the two groups. Similar results were shown in propensity score matching methods. The cardiac complications after laparoscopic RP (OR: 37.71, 95% CI 1.85-768.73, P = 0.018) and open RP (OR: 16.78, 95% CI 1.41-199.51, P = 0.026) were significantly higher than robot-assisted RP (RARP) in patients with AF. The results of trend study indicated that postoperative cardiac complication rates showed a trend of decreasing year by year while the prevalence of AF was rising. Perioperative AF is associated with increased cardiac complications, longer hospital stay and higher cost in PCa patients undergoing RP. RARP may be a preferred choice for patients with AF. Attention should be paid to this special patient population. Reasonable pre-operative risk stratification and standardized management should be done to decrease perioperative complications.

Risk of Recurrent Disease 6 Years After Open or Robotic-assisted Radical Prostatectomy in the Prospective Controlled Trial LAPPRO

BackgroundConclusive evidence of superiority in oncological outcome for robot-assisted laparoscopic prostatectomy (RALP) over retropubic radical prostatectomy (RRP) is lacking. ObjectiveTo compare RALP and RRP regarding recurrent disease and to report the mortality rate 6 yr after surgery. Design, setting, and participantsA total of 4003 men with localized prostate cancer were enrolled between 2008 and 2011 in Laparoscopic Prostatectomy Robot Open (LAPPRO)— a prospective, controlled, nonrandomized trial performed at 14 Swedish centers. Outcome measurements and statistical analysisData were collected at visits and by patient questionnaires at 3, 12, and 24 mo, and through a structured telephone interview at 6 yr. Cause of death was retrieved from the National Cause of Death Register in Sweden. The modified Poisson regression approach was used for analyses. Results and limitationsAfter adjustment for patient-, tumor-, and surgeon-related confounders, no statistically significant difference was observed between RALP and RRP in biochemical recurrence rate (14 vs 16%, relative risk [RR] 0.77, 95% confidence interval [CI] 0.56–1.06) or in not cured endpoint (22% vs 23%, RR 0.82, 95% CI 0.6–1.11). Stratified by D’Amico risk group, a significant benefit for RALP existed for recurrent disease in high-risk patients (RR 0.47, 95% CI 0.26–0.86, p=0.02). All-cause mortality was 3% (n=96). Prostate cancer–specific mortality was 0.6% (n=21) overall, 0.3% (n=8) after RALP, and 1.5% (n=13) after RRP. The nonrandomized design is a limitation. ConclusionsNo significant difference was observed for cancer recurrence rate between RALP and RRP 6 yr after surgery. However, in a subgroup analysis, we found a significant benefit for RALP regarding recurrence rate in the high-risk group. Larger studies with longer follow-up are needed to make a firm conclusion and to evaluate a possible survival benefit. Patient summaryIn general, the oncological outcome is comparable between robotic and open radical prostatectomy 6 yr after surgery. For high-risk patients, our findings indicate that there is an advantage for robotics, but further studies with longer follow-up time is needed to make a firm conclusion.

Comparing the effect of positioning on cerebral autoregulation during radical prostatectomy: a prospective observational study

PurposeSurgery in the prolonged extreme Trendelenburg position may lead to elevated intracranial pressure and compromise cerebral hemodynamic regulation. We hypothesized that robot-assisted radical prostatectomy with head-down tilt causes impairment of cerebral autoregulation compared with open retropubic radical prostatectomy in the supine position.MethodsPatients scheduled for elective radical prostatectomy were included at a tertiary care prostate cancer clinic. Continuous monitoring of the cerebral autoregulation was performed using the correlation method. Based on measurements of cerebral oxygenation with near-infrared spectroscopy and invasive mean arterial blood pressure (MAP), a moving correlation coefficient was calculated to obtain the cerebral oxygenation index as an indicator of cerebral autoregulation. Cerebral autoregulation was measured continuously from induction until recovery from anesthesia.ResultsThere was no significant difference in cerebral autoregulation between robot-assisted and open retropubic radical prostatectomy during induction (p = 0.089), intraoperatively (p = 0.162), and during recovery from anesthesia (p = 0.620). Age (B = 0.311 [95% CI 0.039; 0.583], p = 0.025) and a higher difference between baseline MAP and intraoperative MAP (B = 0.200 [95% CI 0.073; 0.327], p = 0.002) were associated with impaired cerebral autoregulation, whereas surgical technique was not (B = 3.339 [95% CI 1.275; 7.952], p = 0.155).ConclusionCompared with open radical prostatectomy in the supine position, robot-assisted surgery in the extreme Trendelenburg position with capnoperitoneum did not lead to an impairment of cerebral autoregulation during the perioperative period in our study population.Trial registration number: DRKS00010014, date of registration: 21.03.2016, retrospectively registered.

An International Survey on the Use of Thromboprophylaxis in Urological Surgery

BackgroundThe use of perioperative thromboprophylaxis in urological surgery is common but not standardized. ObjectiveTo characterize international practice variation in thromboprophylaxis use in urological surgery. Design, setting, and participantsWe conducted a scenario-based survey addressing the use of mechanical and pharmacological thromboprophylaxis in urological cancer procedures (radical cystectomy [RC], radical prostatectomy [RP], and radical nephrectomy [RN]) among practicing urologists in Canada, Finland, and Japan. The survey presented patient profiles reflecting a spectrum of risk for venous thromboembolism; the respondents described their clinical practice. Outcome measurements and statistical analysisThe proportion of respondents who routinely used (1) mechanical, (2) pharmacological, and (3) extended pharmacological prophylaxis was stratified by procedure. A logistic regression identified characteristics associated with thromboprophylaxis use. Results and limitationsOf 1051 urologists contacted, 570 (54%) participated in the survey. Japanese urologists were less likely to prescribe pharmacological prophylaxis than Canadian or Finnish urologists (p < 0.001 for all procedures). Canadian and Finnish urologists exhibited large variation for extended pharmacological prophylaxis for RP and RN. Finnish urologists were most likely to prescribe extended prophylaxis versus Canadian and Japanese urologists (RC 98%, 84%, and 26%; Open RP 25%, 8%, and 3%; robotic RP 11%, 9%, and 0%; and RN 43%, 7%, and 1%, respectively; p < 0.001 for each procedure). Less variation was found regarding the prescription of mechanical prophylaxis, which was most commonly used until ambulation or discharge. The length of hospital stay was longer in Japan and may bias estimates of extended prophylaxis in Japan. ConclusionsWe found large variation in clinical practice regarding pharmacological thromboprophylaxis within and between countries. Knowledge translation of evidence-based guidelines may reduce problematic international variation in practice. Patient summaryUse of medications to decrease blood clots after urological cancer surgery differs within and between countries. Closer adherence to urology guidelines addressing the prevention of blood clots may decrease this variation and improve patient outcomes.

Sildenafil orodispersible film in the treatment of erectile dysfunction after radical prostatectomy: A single-centre open-label uncontrolled trial.

Phosphodiesterase-5 inhibitors are the first-line therapy for erectile dysfunction (ED) after radical prostatectomy (RP). This single-centre open-label uncontrolled study evaluated the efficacy and safety of the new sildenafil orodispersible film (ODF) in ED treatment after RP. Sildenafil 100mg ODF was administered twice a week for 3months to patients under 75years of age, with a Framingham cardiovascular risk score<20% and a pre-operative International Index of Erectile Function (IIEF)-5 score≥17, who had undergone open RP between 2016 and 2018. Erectile function was assessed pre-operatively, post-operatively and after treatment through the IIEF-5 score, the Sexual Encounter Profile Question (SEP-Q) 2 and SEP-Q3; adverse events (AE) were also investigated after 3months. A total of 65 patients with a median (25th-75th percentile) post-operative IIEF-5 score of 8 (7-9) were treated. Nine (13.8%) patients reported AE of mild/moderate grade and discontinued treatment. A significant IIEF-5 score median (25th-75th percentile) increase of 10 (0-12) was found after treatment in the other 56 patients (p<.001). Sildenafil 100mg ODF was effective in ED after RP in terms of improved IIEF-5 score and improved SEP-Q2 and SEP-Q3 in 67.9% of patients. It could represent a valid alternative for those patients with low compliance to tablet intake.

Effect of pelvimetric diameters on success of surgery in patients submitted to robot-assisted perineal radical prostatectomy.

ABSTRACTObjective:Minimally invasive techniques are used increasingly by virtue of advancements in technology. Surgery for prostate cancer, which has high morbidity, is performed with an increasing momentum based on the successful oncological and functional outcomes as well as cosmetic aspects.Materials and methods:Sixty two patients underwent robot-assisted perineal radical prostatectomy (R-PRP) surgery at our clinic between November 2016 and August 2017. Six pelvimetric dimensions were defined and measured by performing multiparametric magnetic resonance imaging (mpMRI) prior to operation in all patients. In light of these data, we aimed to investigate the effect of pelvimetric measurements on surgery duration and surgical margin positivity.Results:By using this technique in pelvic area, we observed that measurements only representing surgical site and excluding other pelvic organs had a significant effect on surgery duration, and pelvic dimensions had no significant effect on surgical margin positivity.Conclusion:In R-PRP technique, peroperative findings and oncological outcomes can vary depending on several variable factors, but although usually not taken into account, pelvimetric measurements can also affect these outcomes. However, there is a need for randomised controlled trials to be conducted with more patients.

Conservative management of urinary incontinence following robot-assisted radical prostatectomy.

Robotic assisted radical prostatectomy (RARP) is getting more and more popular becoming the most common radical prostatectomy technique. Unfortunately, a not negligible proportion of patients in whom RARP is performed experience urinary incontinence. We aimed to systematically review the current literature evidence on urinary incontinence conservative treatment after RARP. A systematic literature review search using PubMed (Medline), Scopus, and Web of Science databases was performed in December 2019. PRISMA guidelines have been adopted. Population consisted of patients with urinary incontinence after RARP (P), conservative intervention was considered of interest (I). No comparator was considered mandatory (C). Outcomes of interest were the recovery of continence and quality of life (O). Six studies were included. Four of them investigated the use of pelvic floor muscle training (PFMT). PFMT improved pelvic muscle strength. Continence recovery was faster when guided PFMT was adopted. Moreover, two studies tested the effect of solifenacin on urinary incontinence. One of them, a randomized clinical trial, failed to show shorter time to continence in solifenacin group compared to placebo. The use of pads is associated with a detrimental effect on quality of life thus active treatments for UI post-RARP are warranted. PFMT has the main advantage to shorten the time for recovery. The use of solifenacin seems to not offer striking advantages in UI following RARP. Future studies should focus on testing the efficacy of these treatments when used after robotic vs. open radical prostatectomy.

Effect of Pharmacologic Prophylaxis on Venous Thromboembolism After Radical Prostatectomy: The PREVENTER Randomized Clinical Trial

BackgroundDirect high-quality evidence is lacking evaluating perioperative pharmacologic prophylaxis (PP) after radical prostatectomy (RP) to prevent venous thromboembolism (VTE) leading to significant practice variation. ObjectiveTo study the impact of in-hospital PP on symptomatic VTE incidence and adverse events after RP at 30 d, with the secondary objective of evaluating overall VTE in a screening subcohort. Design, setting, and participantsA prospective, phase 4, single-center, randomized trial of men with prostate cancer undergoing open or robotic-assisted laparoscopic RP was conducted (July 2017–November 2018). InterventionPP (subcutaneous heparin) plus routine care versus routine care alone. The screening subcohort was offered lower extremity duplex ultrasound at 30 d. Outcomes measurements and statistical analysisThe primary efficacy outcome was symptomatic VTE incidence (pulmonary embolism [PE] or deep venous thrombosis [DVT]). Primary safety outcomes included the incidence of symptomatic lymphocele, hematoma, or bleeding after surgery. Secondary outcomes were overall VTE, estimated blood loss, total surgical drain output, complications, and surveillance imaging bias. Fisher’s exact test and modified Poisson regression were performed. Results and limitationsA total of 501 patients (75% robotic) were randomized and >99% (500/501) completed follow-up. At second interim analysis (N = 445), the symptomatic VTE rate was 2.3% (four PE + DVT and one DVT) for routine care versus 0.9% (one PE + DVT and one DVT) for PP (relative risk 0.40 [95% confidence interval 0.08–2.03], p = 0.3) meeting a futility threshold for early stopping. In the screening subcohort, the overall VTE rate was 3.3% versus 2.4% (p = 0.7). Results were similar at the final analysis (symptomatic VTE: 2.0% vs 0.8%, p = 0.3; overall VTE: 2.9% vs 2.8%, p = 1). No differences were observed in safety or secondary outcomes. All VTE events (seven symptomatic and three asymptomatic) occurred in patients undergoing pelvic lymph node dissection. ConclusionsThis study was not able to demonstrate a statistically significant reduction in symptomatic VTE associated with PP. There was no increase in the development of symptomatic lymphoceles, bleeding, or other adverse events. Given that the event rate was lower than powered for, further research is needed among high-risk patients (Caprini score ≥8) or patients receiving pelvic lymph node dissection. Patient summaryIn this report, we randomized patients undergoing radical prostatectomy to perioperative pharmacologic prophylaxis or routine care alone. We found that pharmacologic prophylaxis did not reduce postoperative symptomatic venous thromboembolism significantly for men at routine risk. Importantly, pharmacologic prophylaxis did not increase adverse events, such as formation of lymphoceles or bleeding, and can safely be implemented when indicated for patients with risk factors undergoing radical prostatectomy.

Clinical Outcomes of Robotic Surgery Compared to Conventional Surgical Approaches (Laparoscopic or Open): A Systematic Overview of Reviews.

Describe clinical outcomes (eg, postoperative complications, survival) after robotic surgery compared to open or laparoscopic surgery. Robotic surgery utilization has increased over the years across a wide range of surgical procedures. However, evidence supporting improved clinical outcomes after robotic surgery is limited. We systematically searched MEDLINE, EMBASE, and the Cochrane Central Register of systematic reviews from inception to January 2019 for systematic reviews describing postoperative outcomes after robotic surgery. We qualitatively described patient outcomes of commonly performed robotic procedures: radical prostatectomy, hysterectomy, lobectomy, thymectomy, rectal resection, partial nephrectomy, distal gastrectomy, Roux-en-Y gastric bypass, hepatectomy, distal pancreatectomy, and cholecystectomy. One hundred fifty-four systematic reviews included 336 studies and 18 randomized controlled trials reporting on patient outcomes after robotic compared to laparoscopic or open procedures. Data from the randomized controlled trials demonstrate that robotic-assisted radical prostatectomy offered fewer biochemical recurrence and improvement in quality of recovery and pain scores only up to 6 weeks postoperatively compared to open radical prostatectomy. When compared to laparoscopic prostatectomy, robotic surgery offered improved urinary and sexual functions. Robotic surgery for endometrial cancer had fewer conversion to open compared to laparoscopic. Otherwise, robotic surgery outcomes were similar to conventional surgical approaches for other procedures except for radical hysterectomy where minimally invasive approaches may result in patient harm compared to open approach. Robotic surgery has been widely incorporated into practise despite limited supporting evidence. More rigorous research focused on patient-important benefits is needed before further expansion of robotic surgery.

Multi-Institutional Assessment of Routine Same Day Discharge Surgery for Robot-Assisted Radical Prostatectomy.

We assessed the multi-institutional safety of same day discharge for robot-assisted radical prostatectomy within a single health care system. We included 358 patients undergoing planned same day discharge for robot-assisted radical prostatectomy at 6 French centers. Primary outcomes were same day discharge failure, and 30-day complication and readmission rates. Secondary outcomes included preoperative characteristics, perioperative parameters, Chung score and pain visual analogue scale at discharge, pathological features and followup. Mean patient age was 64.7 years. Mean operative time and blood loss were 147.5 minutes and 228 ml, respectively. Concomitant lymph node dissection and nerve sparing procedures were performed in 43% and 62% of cases, respectively. No patient required transfusion or conversion. The same day discharge failure, complication and readmission rates were 4.2%, 16.8% and 2.8%, respectively. The most frequent complications were low grade complications including urinary infection (6.4%) and ileus (2.8%). Blood loss, lymph node dissection and pain visual analogue scale were significantly correlated with same day discharge failure. Same day discharge failure was reported in 7.8% of patients with pelvic lymph node dissection compared with only 1.5% of patients who did not undergo lymph node dissection (p=0.003). ASA® score was the only factor significantly associated with postoperative complications (p=0.023). The only factor correlated with readmission was the pain visual analogue scale at discharge (p=0.017). This first multi-institutional evaluation confirms the safety of same day discharge robot-assisted radical prostatectomy in a single health care system and identifies for the first time factors associated with same day discharge failure and readmission. These findings may help physicians anticipate ideal same day discharge candidates and adapt postoperative followup.

Case of Fournier’s Gangrene in a Patient with Long-Term Indwelling Catheterization due to Urinary Incontinence after Open Radical Prostatectomy

Economic evaluation of robot-assisted radical prostatectomy compared to open radical prostatectomy for prostate cancer treatment in Ontario, Canada.

Recent health technology assessments (HTAs) of robot-assisted radical prostatectomy (RARP) in Ontario and Alberta, Canada, resulted in opposite recommendations, calling into question whether benefits of RARP offset the upfront investment. Therefore, the study objectives were to conduct a cost-utility analysis from a Canadian public payer perspective to determine the cost-effectiveness of RARP. Using a 10-year time horizon, a five-state Markov model was developed to compare RARP to open radical prostatectomy (ORP). Clinical parameters were derived from Canadian observational studies and a recently published systematic review. Costs, resource utilization, and utility values from recent Canadian sources were used to populate the model. Results were presented in terms of increment costs per quality-adjusted life years (QALYs) gained. A probabilistic analysis was conducted, and uncertainty was represented using cost-effectiveness acceptability curves (CEACs). One-way sensitivity analyses were also conducted. Future costs and QALYs were discounted at 1.5%. Total cost of RARP and ORP were $47 033 and $45 332, respectively. Total estimated QALYs were 7.2047 and 7.1385 for RARP and ORP, respectively. The estimated incremental cost-utility ratio (ICUR) was $25 704 in the base-case analysis. At a willingness-to-pay threshold of $50 000 and $100 000 per QALY gained, the probability of RARP being cost-effective was 0.65 and 0.85, respectively. The model was most sensitive to the time horizon. The results of this analysis suggest that RARP is likely to be cost-effective in this Canadian patient population. The results are consistent with Alberta's HTA recommendation and other economic evaluations, but challenges Ontario's reimbursement decision.

Urine colour as an indicator for anastomotic leakage after robot-assisted radical prostatectomy

Objectives: To determine whether macroscopic haematuria predicts urethrovesical anastomotic leakage after robot-assisted laparoscopic radical prostatectomy (RALP) as well as a cystogram.Patients and methods: Participants were recruited before cystogram and catheter removal 5–14 days after RALP surgery. Urine colour in the collection bag was classified according to a three-step scale (clear, light red and dark red) and leakages in cystogram were graded with a four-step scale (Grade 0–3). Diagnostic accuracy parameters were calculated for urine colour. A multivariate logistic regression model was used to evaluate other leakage risk factors.Results: Of 214 patients, 201 (94%) had clear, six (3%) had light red and seven (3%) had dark red coloured urine. In the cystogram, 20 (9%) patients had leakage; 14 had Grade 1, five Grade 2 and one Grade 3 leakage. Overall, specificity and sensitivity of urine colour in predicting anastomotic leakage were 0.97 (95% CI = 0.95–100) and 0.38 (95% CI = 0.17–0.59), respectively. Negative and positive predictive values were 94% and 62%, respectively. Other significant risk factors for anastomotic leakage were previous transurethral resection or radiation therapy to the prostate, non-waterproof anastomosis at surgery, postoperative pelvic haematoma, long catheterization and surgeon’s inexperience. In patients with no other risk factors, test sensitivity improved to 0.80 (95% CI = 0.45–1.15) and negative and positive predictive values to 99% and 44%, respectively.Conclusion: This prospective single-arm trial indicates that in patients with clear urine and no other risk factors for anastomotic leakage, a cystogram examination before urethral catheter removal can be safely omitted.

Salvage open radical prostatectomy for recurrent prostate cancer following MRI-guided transurethral ultrasound ablation (TULSA) of the prostate: feasibility and efficacy

Introduction: MRI-guided transurethral ultrasound ablation (TULSA) is a novel modality for minimally invasive ablation in patients with localised prostate cancer (PCa). A multi-national Phase 1 (30 patients) and subsequent Phase 2 (115 patients) study showed TULSA to be feasible, safe and well tolerated. However, technical viability and safety of salvage prostatectomy for those who failed TULSA is unclear. Herein, we report the feasibility and morbidity of salvage radical prostatectomy (sRP) post-TULSA.Methods: Four patients with biopsy-proven residual cancer following TULSA underwent open retropubic sRP within 39 months of TULSA. Peri-and post-operative morbidity were reported. Detailed histopathologic assessment is reported.Results: Median follow-up was 43 months after sRP. Mean operating times, blood loss, and length of stay were 210 min, 866 ml, and 3.5 days, respectively. Intraoperative finding of some fibrotic reaction of endopelvic and Denonvilliers fascia was characteristic. There were no perioperative complications. Whole-mount pathology sections showed one pT2b and three pT3a, suggesting under-staging pre-TULSA. Location of disease was compatible with persistent cancer mostly in the untreated peripheral safety region. One man received an artificial urinary sphincter. All men experienced erectile dysfunction responsive to treatment. Two patients with positive surgical margins had PSA progression requiring salvage radiation, with one requiring long-term androgen deprivation therapy.Conclusions: RP is a viable and safe salvage option if TULSA fails. Technical difficulty and perioperative morbidity were negligible and attributable to minimal peri-prostatic reaction from TULSA.

Perioperative outcomes of robot-assisted laparoscopic radical prostatectomy (RALRP) and LRP in patients with prostate cancer based on risk groups

ABSTRACT Objective To compare the perioperative and pathological outcomes between robot-assisted laparoscopic radical prostatectomy (RALRP) and LRP based on the patient’s risk. Patients and methods The medical records of 588 patients with prostate cancer who underwent RP, using minimally invasive surgery (MIS) techniques (240 LRP and 348 RALRP) by a single surgeon during January 2008 to June 2018 at the Ramathibodi Hospital, were retrospectively reviewed. The patient’s risk was classified according to the National Comprehensive Cancer Network (NCCN) Guideline, 2018. The demographic, perioperative, and pathological data of patients were collected. The differences in perioperative and pathological outcomes between LRP and RALRP in each risk classification were assessed using chi-square, Fisher’s exact tests and logistic regression, as appropriate. Results In terms of positive margins, RALRP had significant advantages in high-risk patients when compared to LRP (adjusted odds ratio 0.46, 95% confidence interval 0.26–0.84), while there were no differences in the low- and intermediate-risk patients. Overall, the patients who underwent RALRP had significant advantages over those who underwent LRP in terms of operative time, estimate blood loss, and blood transfusion rate. While, adjacent organ injury rate and length of hospital stay were similar for both techniques in all subgroup analyses. Conclusion MIS techniques appear to be safe, especially RALRP, which has significantly better perioperative outcomes in all subgroups of patient risk classification, and in the high-risk patient group it seems to have better pathological outcomes when compared to LRP. Abbreviations EBL: estimated blood loss; LOS: length of hospital stay; PSM: positive surgical margin; (L)(O)(RAL)RP: (laparoscopic) (open) (robot-assisted laparoscopic) radical prostatectomy; MIS: minimally invasive surgery

Workplace absenteeism amongst patients undergoing open vs. robotic radical prostatectomy, hysterectomy, and partial colectomy.

There is controversy regarding the widespread uptake of robotic surgery across several surgical disciplines. While it has been shown to confer clinical benefits such as decreased blood loss and shorter hospital stays, some argue that the benefits of this technology do not outweigh its high cost. We performed a retrospective insurance-based analysis to investigate how undergoing robotic surgery, compared to open surgery, may impact the time in which an employed individual returns to work after undergoing major surgery. We identified a cohort of US adults with employer-sponsored insurance using claims data from the MarketScan database who underwent either open or robotic radical prostatectomy, hysterectomy/myomectomy, and partial colectomy from 2012 to 2016. We performed multiple regression models incorporating propensity scores to assess the effect of robotic vs. open surgery on the number of absent days from work, adjusting for demographic characteristics and baseline absenteeism. In a cohort of 1157 individuals with employer-sponsored insurance, those undergoing open surgery, compared to robotic surgery, had 9.9 more absent workdays for radical prostatectomy (95%CI 5.0 to 14.7, p < 0.001), 25.3 for hysterectomy/myomectomy (95%CI 11.0-39.6, p < 0.001), and 29.8 for partial colectomy (95%CI 14.8-44.8, p < 0.001) CONCLUSION: For the three major procedures studied, robotic surgery was associated with fewer missed days from work compared to open surgery. This information helps payers, patients, and providers better understand some of the indirect benefits of robotic surgery relative to its cost.
