An international consensus for mitigation of the detrimental effects of the COVID-19 pandemic on laparoscopic training.

AIM: Achieve an international consensus on how to recover lost training opportunities. The results of this study will help inform future EAES guidelines about the recovery of surgical training before and after the pandemic. BACKGROUND: A global survey conducted by our team demonstrated significant disruption in surgical training during the COVID-19 pandemic. This was wide-spread and affected all healthcare systems (whether insurance based or funded by public funds) in all participating countries. Thematic analysis revealed the factors perceived by trainees as barriers to training and gave birth to four-point framework of recovery. These are recommendations that can be easily achieved in any country, with minimal resources. Their implementation, however, relies heavily on the active participation and leadership by trainers. Based on the results of the global trainee survey, the authors would like to conduct a Delphi-style survey, addressed to trainers on this occasion, to establish a pragmatic step-by-step approach to improve training during and after the pandemic. METHODS: This will be a mixed qualitative and quantitative study. Semi-structured interviews will be performed with laparoscopic trainers. These will be transcribed and thematic analysis will be applied. A questionnaire will then be proposed; this will be based on both the results of the semi structured interviews and of the global trainee survey. The questionnaire will then be validated by the steering committee of this group (achieve consensus of >80%). After validation, the questionnaire will be disseminated to trainers across the globe. Participants will be asked to consent to participate in further cycles of the Delphi process until more than 80% agreement is achieved. RESULTS: This study will result in a pragmatic framework for continuation of surgical training during and after the pandemic (with special focus on minimally invasive surgery training).

Exploratory analysis on the usage of Pi-score algorithm over endoscopic stone treatment step 1 protocol.

BACKGROUND: The Performance Improvement score (Pi-score) has been proven to be reliable to measure performance improvement during E-BLUS hands-on training sessions. Our study is aimed to adapt and test the score to EST s1 (Endoscopic Stone Treatment step 1) protocol, in consideration of its worldwide adoption for practical training. METHODS: The Pi-score algorithm considers time measurement and number of errors from two different repetitions (first and fifth) of the same training task and compares them to the relative task goals, to produce an objective score. Data were obtained from the first edition of 'ART in Flexible Course', during four courses in Barcelona and Milan. Collected data were independently analyzed by the experts for Pi assessment. Their scores were compared for inter-rater reliability. The average scores from all tutors were then compared to the PI-score provided by our algorithm for each participant, in order to verify their statistical correlation. Kappa statistics were used for comparison analysis. RESULTS: Sixteen hands-on training expert tutors and 47 3rd-year residents in Urology were involved. Concordance found between the 16 proctors' scores was the following: Task 1=0.30 ("fair"); Task 2=0.18 ("slight"); Task 3=0.10 ("slight"); Task 4=0.20, ("slight"). Concordance between Pi-score results and proctor average scores per-participant was the following: Task 1=0.74 ("substantial"); Task 2=0.71 ("substantial"); Task 3=0.46 ("moderate"); Task 4=0.49 ("moderate"). CONCLUSIONS: Our exploratory study demonstrates that Pi-score can be effectively adapted to EST s1. Our algorithm successfully provided an objective score that equals the average performance improvement scores assigned by of a cohort of experts, in relation to a small amount of training attempts.

Frontal theta brain activity varies as a function of surgical experience and task error.

OBJECTIVE: Investigations into surgical expertise have almost exclusively focused on overt behavioral characteristics with little consideration of the underlying neural processes. Recent advances in neuroimaging technologies, for example, wireless, wearable scalp-recorded electroencephalography (EEG), allow an insight into the neural processes governing performance. We used scalp-recorded EEG to examine whether surgical expertise and task performance could be differentiated according to an oscillatory brain activity signal known as frontal theta-a putative biomarker for cognitive control processes. DESIGN SETTING AND PARTICIPANTS: Behavioral and EEG data were acquired from dental surgery trainees with 1 year (n=25) and 4 years of experience (n=20) while they performed low and high difficulty drilling tasks on a virtual reality surgical simulator. EEG power in the 4-7 Hz range in frontal electrodes (indexing frontal theta) was examined as a function of experience, task difficulty and error rate. RESULTS: Frontal theta power was greater for novices relative to experts (p=0.001), but did not vary according to task difficulty (p=0.15) and there was no Experience × Difficulty interaction (p=0.87). Brain-behavior correlations revealed a significant negative relationship between frontal theta and error in the experienced group for the difficult task (r=-0.594, p=0.0058), but no such relationship emerged for novices. CONCLUSION: We find frontal theta power differentiates between surgical experiences but correlates only with error rates for experienced surgeons while performing difficult tasks. These results provide a novel perspective on the relationship between expertise and surgical performance.

The European Urology Residents Education Programme Hands-on Training Format: 4 Years of Hands-on Training Improvements from the European School of Urology.

BACKGROUND: The European School of Urology (ESU) started the European Urology Residents Education Programme (EUREP) in 2003 for final year urology residents, with hands-on training (HOT) added later in 2007. OBJECTIVE: To assess the geographical reach of EUREP, trainee demographics, and individual quality feedback in relation to annual methodology improvements in HOT. DESIGN, SETTING, AND PARTICIPANTS: From September 2014 to October 2017 (four EUREP courses) several new features have been applied to the HOT format of the EUREP course: 1:1 training sessions (2015), fixed 60-min time slots (2016), and standardised teaching methodology (2017). The resulting EUREP HOT format was verified by collecting and prospectively analysing the following data: total number of participants attending different HOT courses; participants' age; country of origin; and feedback obtained annually. RESULTS AND LIMITATIONS: A total of 796 participants from 54 countries participated in 1450 HOT sessions over the last 4 yr. This included 294 (20%) ureteroscopy (URS) sessions, 237 (16.5%) transurethral resection (TUR) sessions, 840 (58%) basic laparoscopic sessions, and 79 (5.5%) intermediate laparoscopic sessions. While 712 residents (89%) were from Europe, 84 (11%) were from non-European nations. Of the European residents, most came from Italy (16%), Germany (15%), Spain (15%), and Romania (8%). Feedback for the basic laparoscopic session showed a constant improvement in scores over the last 4 yr, with the highest scores achieved last year. This included feedback on improvements in tutor rating (p=0.017), organisation (p<0.001), and personal experience with EUREP (p<0.001). Limitations lie in the difficulties associated with the use of an advanced training curriculum with wet laboratory or cadaveric courses in this format, although these could be performed in other training centres in conjunction with EUREP. CONCLUSIONS: The EUREP trainee demographics show that the purpose of the course is being achieved, with excellent feedback reported. While European trainees dominate the demographics, participation from a number of non-European countries suggests continued ESU collaboration with other national societies and wider dissemination of simulation training worldwide. PATIENT SUMMARY: In this paper we look at methodological improvements and feedback for the European Urology Residents Education Programme hands-on-training over the last 4 yr.

A Multispecialty Evaluation of Thiel Cadavers for Surgical Training.

BACKGROUND: Changes in UK legislation allow for surgical procedures to be performed on cadavers. The aim of this study was to assess Thiel cadavers as high-fidelity simulators and to examine their suitability for surgical training. METHODS: Surgeons from various specialties were invited to attend a 1 day dissection workshop using Thiel cadavers. The surgeons completed a baseline questionnaire on cadaveric simulation. At the end of the workshop, they completed a similar questionnaire based on their experience with Thiel cadavers. Comparing the answers in the pre- and post-workshop questionnaires assessed whether using Thiel cadavers had changed the surgeons' opinions of cadaveric simulation. RESULTS: According to the 27 participants, simulation is important for surgical training and a full-procedure model is beneficial for all levels of training. Currently, there is dissatisfaction with existing models and a need for high-fidelity alternatives. After the workshop, surgeons concluded that Thiel cadavers are suitable for surgical simulation (p = 0.015). Thiel were found to be realistic (p < 0.001) to have reduced odour (p = 0.002) and be more cost-effective (p = 0.003). Ethical constraints were considered to be small. CONCLUSION: Thiel cadavers are suitable for training in most surgical specialties.

Seminoma presented as testicular rupture: Case report and literature review.

Rupture of the testis as a result of blunt trauma is rarely seen in daily urological practice. We report an unusual case of incidental seminoma diagnosed after surgical exploration and subsequent orchidectomy of a severed testis following testicular injury as a result of trivial blunt trauma. This case highlights the inability of investigative tools, such as a scrotal ultrasound, in distinguishing an underlying tumour in the presence of testicular parenchymal damage. We therefore advocate a high index of clinical suspicion for co-existing pathology in cases of testicular rupture secondary to an insignificant blunt trauma to the scrotum.

Fulguration of the lumen does not improve vasectomy sterilization rates.

OBJECTIVES: To assess the effect of adding lumen diathermy fulguration to our standard technique of vas ligation with polyglactin 910 (Vicryl(TM), Ethicon, Sommerville, NJ, USA) excision and fascial interposition, in an attempt to improve our sterilization rates. We previously reported the effect of changing suture material on vasectomy success rates; 3005 post-vasectomy semen analyses (PVSA) revealed a decrease in sterilization rates after surgery on changing from chromic catgut to polyglactin 910. PATIENTS AND METHODS: We retrospectively reviewed PVSA undertaken for vasectomies performed by urological surgeons at the Mid-Yorkshire NHS Trust for 18 months from September 2005 to February 2007. RESULTS: There were 592 vasectomies in all; the age distribution of patients between the groups treated with the standard and new method was similar. Overall, 166 patients (28%) failed to provide two semen samples as instructed, and so were excluded from further analyses. Sterility was achieved in 367 patients (86%); a further 28 (7%) have indeterminate analyses to date, with one of the last two PVSAs showing sperm, with the PVSA of 32 (7%) patients showing persisting sperm. For the eight surgeons reviewed the sterility rates were broadly similar. CONCLUSIONS: The introduction of diathermy fulguration of the lumen has not improved vasectomy sterilization rates, with up to 14% having sperm on PVSA.
