Implementation and Validation of an Automated, Longitudinal Robotic Surgical Evaluation and Feedback Program at a High-volume Center and Impact on Training.

Background: Surgical education lacks a standardized, proficiency-based approach to evaluation and feedback. Objective: To assess the implementation and reception (ie, feasibility) of an automated, standardized, longitudinal surgical skill assessment and feedback system, and identify baseline trainee (resident and fellow) characteristics associated with achieving proficiency in robotic surgery while learning robotic-assisted laparoscopic prostatectomy. Design setting and participants: A quality improvement study assessing a pilot of a surgical experience tracking program was conducted over 1 yr. Participants were six fellows, eight residents, and nine attending surgeons at a tertiary cancer center. Intervention: Trainees underwent baseline self-assessment. After each surgery, an evaluation was completed independently by the trainee and attending surgeons. Performance was rated on a five-point anchored Likert scale (trainees were considered "proficient" when attending surgeons' rating was ≥4). Technical skills were assessed using the Global Evaluative Assessment of Robotic Skills (GEARS) and Prostatectomy Assessment and Competency Evaluation (PACE). Outcome measurements and statistical analysis: Program success and utility were assessed by evaluating completion rates, evaluation completion times, and concordance rates between attending and trainee surgeons, and exit surveys. Baseline characteristics were assessed to determine associations with achieving proficiency. Results and limitations: Completion rates for trainees and attending surgeons were 72% and 77%, respectively. Fellows performed more steps/cases than residents (median [interquartile range]: 5 [3-7] and 3 [2-4], respectively; p < 0.01). Prior completion of robotics or laparoscopic skill courses and surgical experience measures were associated with achieving proficiency in multiple surgical steps and GEARS domains. Interclass correlation coefficients on individual components were 0.27-0.47 on GEARS domains. Conclusions: An automated surgical experience tracker with structured, longitudinal evaluation and feedback can be implemented with good participation and minimal participant time commitment, and can guide curricular development in a proficiency-based education program by identifying modifiable factors associated with proficiency, individualizing education, and identifying improvement areas within the education program. Patient summary: An automated, standardized, longitudinal surgical skill assessment and feedback system can be implemented successfully in surgical education settings and used to inform education plans and predict trainee proficiency.

The diagnosis and treatment of castrate-sensitive oligometastatic prostate cancer: A review.

BACKGROUND: Oligometastatic prostate cancer (OMPCa) is emerging as a transitional disease state between localized and polymetastatic disease. This review will assess the current knowledge of castrate-sensitive OMPCa. METHODS: A review of the current literature was performed to summarize the definition and classification of OMPCa, assess the diagnostic methods and imaging modalities utilized, and to review the treatment options and outcomes. We further identify gaps in knowledge and areas for future research. RESULTS: Currently there is no unified definition of OMPCa. National guidelines mostly recommend systemic therapies without distinguishing oligometastatic and polymetastatic disease. Next generation imaging is more sensitive than conventional imaging and has led to early detection of metastases at initial diagnosis or recurrence. While mostly retrospective in nature, recent studies suggest that treatment (surgical or radiation) of the primary tumor and/or metastatic sites might delay initiation of androgen deprivation therapy while increasing survival in selected patients. CONCLUSIONS: Prospective data are required to better assess the incremental improvement in survival and quality of life achieved with various treatment strategies in patients with OMPCa.

Representation of patients with non-English language preferences in motor vehicle collision trauma and emergency medicine research.

BACKGROUND: Individuals with non-English language preferences (NELP) represent a growing proportion of the USA population. Prior studies demonstrate disparate health outcomes related to NELP status; however, this patient population is often excluded from medical research. There is a paucity of literature describing the impact of NELP status on trauma, specifically injury and outcomes related to vehicle occupants injured during motor vehicle collisions (MVCs). The goal of this study was to evaluate the representation of patients with NELP in both emergency medicine and trauma literature. METHODS: We conducted a systematic search of US-based publications from 2010 to 2021. Titles, abstracts and full texts of eligible articles were evaluated. Data were extracted using an a priori determined standardised reporting tool to evaluate language as study inclusion/exclusion criteria, manuscript reporting of language, assessment of language as a primary variable and consideration of language in study methodology. RESULTS: A total of 82 studies met inclusion criteria. Twenty-three studies (28%) excluded NELP populations and only one study explicitly included the NELP population. None of the studies evaluated language as a primary outcome of the study or included language as a variable in the analysis. Over half of the studies (53.6%) used a public data set or registry. CONCLUSION: NELP populations are routinely excluded from and are difficult to identify in MVC trauma research. Without appropriate inclusion and identification, it will be difficult to understand the prevalence and outcomes of traumatic injury in NELP patients and to develop culturally and linguistically appropriate interventions.

Should Transperineal Prostate Biopsy Be the Standard of Care?

PURPOSE OF REVIEW: We reviewed the advantages and disadvantages of transperineal prostate biopsy (TP-bx) to evaluate its potential role as the standard of care for prostate biopsy. RECENT FINDINGS: Studies have suggested no difference in prostate cancer (PCa) detection rate between TP-bx and transrectal biopsy (TR-bx) but have suggested potentially increased detection of anterior prostate tumors. Advances in anesthetic technique have obviated the need for sedation thus allowing TP-bx to become an office-based procedure, which in turn can decrease the overall cost of TP-bx. Furthermore, given the low rate of infectious complications after TP-bx, some have foregone peri-procedural antibiotics without a change in the rate of infectious complications. Recent procedural advances have made TP-bx a tolerable, office-based procedure. Given the similar diagnostic performance and the benefits for the patient and community, TP-bx should become the standard of care for prostate biopsy for most patients. Future efforts should address the barriers for more universal adoption.

A Novel Expert Coaching Model in Urology, Aimed at Accelerating the Learning Curve in Robotic Prostatectomy.

INTRODUCTION/BACKGROUND: The surgical residency model assumes that upon completion, a surgeon is ready to practice and grow independently. However, many surgeons fail to improve after reaching proficiency, which in certain instances has correlated with worse clinical outcomes. Coaching addresses this problem and furthers surgeons' education post-residency. Currently, surgical coaching programs focus on medical students and residents, and have been shown to improve residents' and medical students' technical and non-technical abilities. Coaching programs also increase the accuracy of residents, fellows, and attendings in self-assessing their surgical ability. Despite the potential benefits, coaching remains underutilized and poorly studied. We developed an expert-led, face-to-face, video-based surgical coaching program at a tertiary medical center among specialized attending surgeons. Our goal was to evaluate the feasibility of such a program, measure surgeons' attitudes towards internal peer coaching, determine whether surgeons found the sessions valuable and educational, and to subjectively self-assess changes in operative technique. METHODS/MATERIALS: Surgeons who perform robot-assisted laparoscopic prostatectomies were chosen and grouped by number of cases completed: junior (<100 cases), intermediate (100-500 cases), and senior (>500 cases). Surgeons were scheduled for 3 1-hour coaching sessions 1-2 months apart (February-October 2019), meeting individually with the coach (PS), an expert Urologic Oncologist with thousands of cases of experience performing radical prostatectomy. He received training on coaching methodology prior to beginning the coaching program. Before each session, surgeons selected 1 of their recent intraoperative videos to review. During sessions, the coach led discussion on topics chosen by the surgeon (i.e. neurovascular bundle dissection, apical dissection, bladder neck); together, they developed goals to achieve before the next session. Subsequent sessions included presentation and discussion of a case occurring subsequent to the prior session. Sessions were coded by discussion topics and analyzed based on level of experience. Surgeons completed a survey evaluating the experience. RESULTS: All 6 surgeons completed 3 sessions. Five surgeons completed the survey; most respondents evaluated themselves as having improved in desired areas and feeling more confident performing the discussed steps of the operation. Discussed surgical principles varied by experience group; when subjectively quantifying the difficulty of surgical steps, the more difficult steps were discussed by the higher experience groups compared to the junior surgeons. The senior surgeons also focused more on oncologic potency, continence outcomes, and more theory-driven questions while the junior surgeons tended to focus more on anatomic and technique-based questions such as tissue handling and the use of cautery and clips. Overall, the surgeons thought this program provoked critical discussion and subsequently modified their technique, and "agreed" or "strongly agreed" that they would seek further sessions. CONCLUSIONS: Surgical coaching at a large medical center is not only feasible but was rated positively by surgeons across all levels of experience. Coaching led to subjective self-improvement and increased self-confidence among most surgeons. Surgeons also felt that this program offered a safe space to acquire new skills and think critically after finishing residency/fellowship. Themes discussed and takeaways from the sessions varied based on surgeon experience level. While further research is needed to more objectively quantify the impact coaching has on surgeon metrics and patient outcomes, the results of this study supports the initial "proof-of-concept" of peer-based surgical coaching and its potential benefits in accelerating the learning curve for surgeons' post-residency.

Prostate Cancer Screening for Gay Men in the United States.

OBJECTIVE: To elucidate trends of prostate-cancer (PCa) screening in gay and bisexual men and assess the association of sexual orientation with PCa screening in the United States of America. METHODS: Data for men ≥40 years-old with no history of PCa were collected from the National Health Interview Survey for the years 2013, 2015, and 2018. Multivariable logistic regression models were created to determine the associations between sexual orientation and PCa screening and the discussion of advantages and disadvantages prior to PCa screening. RESULTS: Gay men screened for prostate cancer were younger than their straight counterparts with a median age (IQR) of 58 years (52-66) vs 64 years (56-71). Gay men were more likely to have undergone a screening PSA test (OR 1.56; 95% CI 1.20-2.02) and discuss the advantages of PSA testing with the physician prior to the test (OR 1.64; 95% CI 1.22-2.21) when compared to straight men. In yearly analysis, gay men were more likely to have undergone screening in 2013 (OR 1.65, 95% CI 1.01-2.68) and 2015 (OR 1.95, 95 CI% 1.30-2.91), however, there was no difference when compared to straight men in 2018 (OR 1.32, 95% CI 0.85-2.04). CONCLUSION: Gay men were screened for PCa at a younger age comparted to straight men. They were also more likely to have undergone PCa cancer screening than straight men between 2013 and 2018. Further study is needed to better understand the role of sexual orientation in PCa screening and management.

Comparative Effectiveness and Tolerability of Transperineal MRI-Targeted Prostate Biopsy under Local versus Sedation.

OBJECTIVES: To assess the prostate cancer diagnostic yield, complications, and costs of transperineal prostate biopsies when performed with local anesthesia versus sedation. METHODS: Data were prospectively collected for men undergoing transperineal MRI-targeted biopsy at the outpatient clinic and tertiary hospital of a single center between October 2017 to February 2020. These data included demographic, procedural, and pathologic variables and complications. Time-driven activity-based costing was performed to compare procedural costs. RESULTS: 126 men were included. Age, BMI and PSA were similar for local (n = 45) vs sedation (n = 81), all P>0.05. Detection of clinically significant prostate cancer (CSPC) on combined systematic and targeted biopsy was similar for local vs sedation (24% vs 36%; P = 0.2). Local had lower detection on targeted biopsies alone (8.9% vs 25%; P = 0.03). However, fewer targeted cores were obtained per region of interest with local vs sedation (median 3 vs 4 cores; P<0.01). For local vs sedation, the complication rate was 2.6% and 6.1% (P = 0.6). The median visual analog pain score for local vs sedation was 3/10 vs 0/10 (P<0.01). The mean procedure time for local vs sedation was 22.5 vs 17.5 minutes (48.3 minutes when including anesthesia time). Time-driven activity-based costs for local vs sedation were $961.64 vs $2208.16 (P<0.01). CONCLUSION: Transperineal biopsy with local anesthesia is safe with comparable outcomes to sedation. While the number of cores taken differed, there was no statistical difference in the detection of clinically significant cancer.

Microwave ablation of cT1a renal cell carcinoma: oncologic and functional outcomes at a single center.

PURPOSE: Percutaneous ablation is an established alternative to surgical intervention for small renal masses. Radiofrequency and cryoablation have been studied extensively in the literature. To date, series assessing the efficacy and safety of microwave ablation (MWA) are limited. We present a cohort of 110 renal tumors treated with MWA. METHODS: A review of the medical record between January 2015 and July 2019 was performed, retrospectively identifying 101 patients (110 tumors). All ablations were performed by a single board-certified urologist/interventional radiologist. Demographic information, intraoperative, postoperative, and follow-up surveillance data were recorded. RESULTS: Median (IQR) age was 69.7 years (60.8-77.0); 27 (24%) were female. Median (IQR) BMI was 27.0 (25.1-30.2) and Charleston Comorbidity Index was 5.0 (4.0-6.0). 82 tumors were biopsy-confirmed renal cell carcinoma/oncocytic neoplasms. Median (IQR) tumor size was 2.0 cm (1.5-2.6). Median (IQR) RENAL nephrometry score was 6.0 (5.0-8.0). Technical success was achieved in all patients and all but one patient were discharged on the same day. Median (IQR) eGFR at baseline and 1 year were 71.9 mL/min/1.73 m2 (56.5-82) and 63.0 mL/min/1.73 m2 (54.0-78.2); the difference was -5.3 (p = 0.12). Two Clavien-Dindo type-I complications, one type-II complication, and one type-III complication were experienced in this cohort. Median radiographic follow-up was 376.5 days with 2 tumors (2.4% of RCC/oncocytic neoplasms) having recurred to date. CONCLUSIONS: MWA is a safe and efficacious treatment option for small renal masses with minimal adverse events and low rates of recurrence in this cohort of 101 patients. Continued follow-up is needed to assess long-term outcomes.

Presentation and resolution of gender dysphoria as a positive symptom in a young schizophrenic man who presented with self-emasculation: Frontiers of bioethics, psychiatry, and microsurgical genital reconstruction.

Gender dysphoria can present as a positive symptom of schizophrenia. Completion of gender affirmation surgeries should not occur as a result of male genital self-mutilation via a deferral of emergent surgical reconstruction. Instead, gender affirmation should be considered after a full workup and assessment for resolution of any acute psychosis.

Effect of waiting time estimates on patients satisfaction in the emergency department in a tertiary care center.

OBJECTIVES: To examine the influence of emergency department (ED) waiting time estimate provision on the satisfaction of patients.  Methods: This was a randomized controlled trial at King Abdulaziz Medical City, Riyadh, Saudi Arabia between September 2017 and May 2018. It included 18 to 70 years old Arabic-speaking acute care patients. After being divided into 2 groups, the intervention group alone was provided waiting time estimates. Both groups answered 2 questionnaires evaluating their satisfaction and illness perception before and after seeing a doctor. Results: One-hundred patients were included. No significant difference found in waiting time satisfaction scores between groups (intervention (5.92/10±3.13), control (5.45/10±3.38), p=0.476). Demographics and illness perception had an insignificant impact on satisfaction. Waiting time estimate was preferred by most participants (70%). Conclusion: Providing waiting time estimation did not affect satisfaction but was preferred to have in the ED by most.

Management of the Small Renal Mass: a 2020 Update.

PURPOSE OF REVIEW: Small renal masses (≤ cT1a, less than 4 cm) are a subset of renal tumors with low malignant and metastatic potential but increasing incidence given increased use of cross-sectional imaging. Here, we review the diagnostic and treatment options available for the lesions. RECENT FINDINGS: While the low metastatic potential of SRMs has been known, recent studies show that 30% of SRMs removed surgically are benign. Renal biopsy is a tool that can be implemented to help with diagnosis before treatment (options of which include active surveillance, ablation, and surgery). Active surveillance might be associated with worse cancer-specific survival but all interventional methods appear to fare similarly. Advancements have also been made in percutaneous ablation techniques, and they now are included on multiple guideline statements. Active surveillance, surgery (PN and RN), and thermal ablation are all treatment options for SRMs with similar outcomes but varying side effects.

Utility of dynamic MRA in the evaluation of male erectile dysfunction.

PURPOSE: To assess the efficacy of time-resolved MR angiography (MRA) in evaluating penile vasculature in patients with clinically suspected vascular anomalies contributing to their erectile dysfunction correlating with penile doppler ultrasound (PDUS) findings and clinical outcomes after surgical intervention. METHODS: Men (n = 26) with signs of early vascular shunting on PDUS underwent time-resolved, contrast-enhanced (0.1 mMol/kg gadobutrol at 1 ml/s followed by saline flush) 3-dimensional spoiled gradient echo T1-weighted MRA sequence performed over 3 min with 4.6 s frame rate after intracavernosal injection of an erectogenic agent. Additional T1- and T2-weighted sequences were performed for anatomic co-localization and tissue characterization. MRA images were evaluated for early filling of draining veins as well as arteriovenous malformations and fistulas and correlated with findings at surgery. RESULTS: 29 MRA examinations on 26 patients (mean age 39 years) demonstrated abnormal early venous drainage (n = 22) as well as diminutive/delayed cavernosal enhancement (n = 3), incomplete tumescence (n = 2), and combined arterial inflow/venous outflow disease (n = 1). The MRA had a concordance of 85.2% at determining the presence, or lack thereof of a shunt/AVM when compared to PDUS. CONCLUSIONS: Time-resolved MRA allows for both temporal and spatial resolution with visualization of both arterial and venous abnormalities which may be suggested with a screening PDUS examination. This technique allows us to provide detailed anatomic information prior to any surgical intervention.

Nephron-sparing surgery for Wilms tumor: A systematic review.

INTRODUCTION: Radical nephrectomy (RN, or total nephrectomy) is the current gold-standard surgical treatment for children with Wilms tumors (WT). However, nephron-sparing surgery (NSS, or partial nephrectomy) has recently been gaining increasing attention. The objective of this systematic review is to compare the effectiveness of NSS as compared with RN for the treatment of children with WT. METHODS: We searched the Cochrane Controlled Trials Register, clinicaltrials.gov, MEDLINE, EMBASE, Google Scholar, and recently presented meeting abstracts for reports in English. The bibliographies of included studies were then hand-searched for any missed articles. The protocol was prospectively registered. Manuscripts were assessed and data abstracted in duplicate with differences resolved by the senior author. Owing to high heterogeneity among the final included studies, only a qualitative systematic review was performed; no formal meta-analysis was undertaken. RESULTS: We identified 694 articles, 118 of which were selected for full-text review and 66 of which were included in the final analysis. Most studies were single- or multi-institution retrospective case series (60, 91%), with a small number of prospective cohort studies (6, 9%) and 1 administrative database analysis. Most studies were from Europe (27, 41%) or North America (21, 32%). Nearly half (32, 48%) of studies those were included were dated from 2010 or later. In total, data on 4,002 patients were included, of whom 1,040 (26%) underwent NSS and 2,962 (74%) underwent NSS. Reported rupture rates were similar between RN and NSS (13% vs. 7%), as were recurrence rates (12% vs. 11%) and survival rates (85% vs. 88%). However, these comparisons are limited by inherent biases in the design and reporting of most included studies. CONCLUSIONS: Most contemporary studies reporting the use of NSS in children with WT report similar long-term outcomes to RN. However, most existing studies are limited by their small numbers, inconsistent reporting, and methodological biases. There are significant opportunities for future research on the use of NSS in children with WT, including issues related to surgical quality, optimal technique, timing and duration of chemotherapy, and variation in the use of NSS among centers.

In vivo macrophage recruitment by murine intervertebral disc cells.

SUMMARY: An in vivo murine experiment was conducted to measure the capacities of viable intervertebral disc cells to recruit inflammatory cells. The objective was to determine whether compounds secreted from viable cells induce inflammation or whether inflammation in disc herniation simply requires exposure to structural cell or matrix components. Three tissue preparations were inserted into the right lower peritoneal cavity of male mice: tissue with viable annulus fibrosus and nucleus pulposus cells, tissue with viable annulus fibrosus cells, or devitalized annulus fibrosus and nucleus pulposus tissue. Controls included sham-operated and nonoperated groups. Mice were killed 1, 2, or 7 days after surgery. Macrophage recruitment occurred after exposure to viable disc tissue but not after exposure to devitalized disc components; recruitment increased over time. Viable disc cells play a role in the etiology of inflammation in disc herniation.

An earthquake disaster in Turkey: assessment of the need for plastic surgery services in a crisis intervention field hospital.

On August 17, 1999, an earthquake of 7.4 magnitude struck Turkey, resulting in the destruction of the cities Golcuk, Izmit, Adapazari, and Yalova. Three days later, the Israel Defense Force Field Hospital arrived at Adapazari, serving as a reinforcement hospital until the rehabilitation of the local medical facilities. Surgical services in the field hospital were supplied by general, orthopedic, and plastic surgeons. The authors evaluated all soft-tissue injuries managed at the hospital and assessed the need for plastic surgery services in a crisis intervention field hospital. Information was gathered regarding soft-tissue injuries throughout the activity of the hospital. In addition, patients' charts, operations' reports, and entry and evacuation logs were reviewed for all patients accepted and treated in the field hospital. Interviews of patients, local physicians, and citizens of Adapazari were performed to evaluate the medical situation in the first 3 days after the earthquake. A total of 1205 patients were treated by the field hospital in Adapazari; 138 (11.45 percent) of these patients sought aid for isolated soft-tissue injuries, 105 of which (76.09 percent) were earthquake-related. Twenty (51.28 percent) of the operations performed in the hospital were to treat soft-tissue injuries; 1.49 percent of all patients underwent minor surgical manipulations by the plastic surgeon on staff. Plastic surgery patients occupied 13.6 percent of the hospital beds. In conclusion, the authors find it beneficial to supply plastic surgery services at a field hospital in an earthquake situation.

The "rubber band technique": a simple method for closing large skin defects.

Traditional methods of obtaining definitive soft-tissue cover in open wounds after high-energy trauma necessitate repeated surgical procedures and sophisticated soft-tissue reconstructions. A simple one-stage technique to treat skin loss in severe open fractures is described. The "rubber band technique" enables postoperative exposure and drainage of the fracture site. The wound closes gradually by facilitated mobilization of skin in response to continuous tension from the rubber band. This technique may prevent the need for additional procedures. Continuous drainage is achieved. When deep infection is suspected, removal of the elastic rubber band permits sufficient exposure of the deep tissues. The "rubber band technique" has proved to be a safe, simple, and efficient method for treating extensive soft-tissue loss in open fractures and after incisions for open reduction or fasciotomy.

Degenerative lumbar stenosis: diagnosis and management.

Degenerative lumbar stenosis is a common cause of disabling back and lower extremity pain among older persons. The process usually begins with degeneration of the intervertebral disks and facet joints, resulting in narrowing of the spinal canal and neural foramina. Associated factors may include a developmentally narrow spinal canal and degenerative spinal instability. Nonoperative management includes restriction of aggravating activities, physical therapy, and anti-inflammatory medications. If nonoperative treatment has failed, surgical treatment may be appropriate. Decompression should be performed so as to address all clinically relevant neural elements while maintaining spinal stability. If instability is present, autogenous intertransverse bone grafting is recommended. There may be an advantage to augmenting some of these procedures with internal fixation. Surgical success rates as high as 85% have been reported, but may be compromised by inadequate decompression, inadequate stabilization, or medical comorbidities. Short-term follow-up data indicate that operative management provides more effective relief than nonoperative treatment, but prospective studies comparing the effects of nonoperative and operative interventions on the long-term natural history of lumbar spinal stenosis are needed.
