RESUMO

PURPOSE OF THE STUDY We hypothesized that preoperative planning with 3D modeling of complex foot deformities would be useful for the education of orthopedics and traumatology residents. MATERIAL AND METHODS This study is prospectively designed study with a control group. Twenty eight residents (study group) who assisted the surgeons during the interventions and ten senior surgeons (control group) were included in the study. All participants assessed virtual 3D-CT images and videos of the cases before the surgery. Ten adult cases of foot bone deformities were evaluated. 3D-CT reconstruction was performed and a 3D model of each deformity was created using the hospital's picture archiving and communication system. The completed 3D models were sterilized in hydrogen peroxide and put on the surgical table in a sterile manner. After surgery, the residents (group I) and surgeons (group II) were questioned regarding their satisfaction with 3D modeling. Responses were structured by a five-point Likert scale (1, strongly disagree; 2, disagree; 3, neither agree nor disagree; 4, agree; and 5, strongly agree). RESULTS The surgeons (group II, n = 10) were satisfied with the sterilized 3D models, which they could touch and re-examine on the operating table. The residents (group I, n = 28) were significantly more satisfied than the senior surgeons (p=0.01). The 3D modeling met both the surgeons' and residents' expectations. DISCUSSION The survey results for the surgeons (group II) were satisfied with the sterilized 3D models, which they could touch and reexamine on the operating table (question 3). They gave the best scores (mean, 4.8/5) for clarity of the 3D model. On the other hand, they gave the lowest scores (mean 3.1/5) to 3D models due to its contribution in understanding deformity over virtual 3D-CT evaluations (question 2 and 5). The residents (group I) differed from those for the senior surgeons. Residents gave the highest scores for understanding of the deformity (question 2 and 5) and clarity (question 1). These outcomes may be interpreted to indicate i) that 3D modeling may be used for education, and ii) that younger surgeons are more interested in novel technological developments. Therefore, the outcomes did differ significantly between the senior surgeons and residents (Table 1). These outcomes may be explicated as; 3D modeling of the foot deformities may not be mandatory for the experienced surgeons for understanding the deformity. On the other hand 3D modeling would be useful tools for younger surgeons and for their education. CONCLUSIONS 3D modeling of foot deformities is more informative than virtual 3D videos. However, with consideration of costs and long processing times, 3D printing may be used optimally for rare deformities. When considering the role of touch sense in surgical learning, 3D modeling gives more detailed and more satisfactory planning than virtual 3D videos. 3D modeling is more useful for young surgeons, and it will be used mainly for education in the future. Key words: 3D printing, deformity, foot and ankle, simulation.

RESUMO

The purpose of this study was to evaluate the operative experience of orthopaedic surgeons in the various deployment locations since 2012. We also evaluated the implications of humanitarian surgical care and the impact of deployment on an orthopaedic practice. An emailed survey was sent to orthopaedic surgeons deployed after 2012. The survey was 48 questions. Most cases in Iraq, Afghanistan and Syria were emergent traumas. In other locations, however, most cases were elective/non-emergent cases. Of surgeons surveyed, 44% performed less than 10 cases during their deployment, and 50% considered humanitarian surgery part of their mission. Six weeks was needed to prepare for deployment, and 4.4 weeks to re-build a practice. Disparity exists in surgical case volume and types of cases performed by orthopaedic surgeons that is dependent on deployed location. This dichotomy in operative experience places surgeons deployed to such locations at risk of losing surgical skills. (Journal of Surgical Orthopaedic Advances 29(3):182-186, 2020).

RESUMO

The article deals with the relevant literature data concerning diagnosis and treatment of subclavian artery aneurysms. This nosological entity is relatively uncommon, however its importance for modern medicine should not be underestimated. Despite a low incidence of the pathology, it should be understood that the disease's course for the patient is associated with the development of severe complications which may lead to disability or even death. The development of complications is extremely difficult to predict and stratification of risks for such patients is too complicated. It is also known that the diagnosis of a subclavian artery aneurysm is frequently an accidental finding, since the pathology may for a long time proceed symptom-free. At the same time, the subclavian artery occupies the first place by the frequency of localization of upper-limb aneurysms, thus making this problem currently important. Besides, separate attention should be paid to modern methods of correction of this disease, since implementation of high-tech interventions into vascular surgery have significantly expanded the arsenal of the operating surgeon.

RESUMO

The mental and physiological stress experienced by surgeons during operations has been identified as an important human factor that impacts surgical performance and patient safety. It is crucial to objectively measure and quantify surgeons' stress via physiological signals in order to enhance the understanding of how stress contributes to surgical outcomes. Current clinical and consumer devices for monitoring bio signals are not well adapted for use in the operating room; therefore, we designed an unobtrusive system, that measures select signals that correlate with stress and stores the data for integration into a data processing pipeline. Herein, we present a proof-of-concept device that captures data from ECG, EMG, EDA, and IMU sensors and initial testing results.

RESUMO

Background: For the benefits of less postoperative pain, early recovery and discharge, and better cosmesis, laparoscopic surgery is rapidly gaining acceptance amongst surgeons as a better alternative to traditional open procedures. In January 2015, bookings for laparoscopic surgery became a more regular feature on our operation list. Aims: We reported the indications, management outcome, and challenges in patients who had laparoscopic surgery in our institution. This is to document the trends in our surgical practice. Methodology: This is a descriptive study of 137 patients who had laparoscopic surgery for general surgical indications in our institution over a period of 5 years. Patients data as collected from the records department were evaluated for demographic characteristics, medical comorbidities, type of procedures done, and perioperative outcome. Data analysis was performed using Statistical Package for Social Sciences (SPSS). Results: A total of 137 Patients had laparoscopic general surgery between January 2015 and December 2019. There were 48 males and 89 females with a male-to-female ratio of 1:1.9. The mean age of the patients was 38.8 ± 3.4 years (range 16-87 years). Laparoscopic cholecystectomy (35%) and laparoscopic appendicectomy (29.9%) were the most common procedures performed. Five (3.7%) cases were converted to open surgery. Superficial surgical site infection (5.8%) following laparoscopic appendicectomy was the most common postoperative complication. There was no 30-day postoperative mortality. Conclusion: Laparoscopic surgery is safe and can be applied to wide variety of general surgical conditions in developing countries. Minimal postoperative morbidity of laparoscopy is a major benefit to the patients.

RESUMO

Increasing workload is one of the main problems that surgical practices face. This increase is not only due to the increasing demand volume but also due to increasing case complexity. This raises the question on how to measure and predict the complexity to address this issue. Predicting surgical duration is critical to parametrize surgical complexity, improve surgeon satisfaction by avoiding unexpected overtime, and improve operation room utilization. Our objective is to utilize the historical data on surgical operations to obtain complexity groups and use this groups to improve practice.Our study first leverages expert opinion on the surgical complexity to identify surgical groups. Then, we use a tree-based method on a large retrospective dataset to identify similar complexity groups by utilizing the surgical features and using surgical duration as a response variable. After obtaining the surgical groups by using two methods, we statistically compare expert-based grouping with the data-based grouping. This comparison shows that a tree-based method can provide complexity groups similar to the ones generated by an expert by using features that are available at the time of surgical listing. These results suggest that one can take advantage of available data to provide surgical duration predictions that are data-driven, evidence-based, and practically relevant.

RESUMO

Mitral valve regurgitation is one of the most common heart valve diseases and mitral valve repair is the favored therapy, in which a part of the mitral valve is resected. To improve preoperative planning of this challenging surgery, patient-specific mitral valve replicas have been developed on which the repair can be simulated. However, there is no possibility yet to transfer the planning from the replica to the surgery of the patient. To solve this problem, we developed a patient-specific instrument with a cutting template, intraoperatively visualizing the part of the mitral valve to be resected as planned on the replica. To realize this instrument, the surgeon first simulates mitral valve repair by resection on a patient-specific mitral valve replica. This postoperative mitral valve replica is then digitalized and from it and a preoperative mitral valve model the instrument with cutting template is automatically designed and then 3D printed. An expert heart surgeon successfully tested the functional principle of the instrument on a pig mitral valve.

RESUMO

BACKGROUND: Enhanced Recovery After Surgery (ERAS) protocols use evidence-based perioperative practices that reduce morbidity and length of stay and improve patient satisfaction. ERAS is considered standard of care; however, utilization remains low and substantial practice variation exists. The aim of this study was to pragmatically characterize variation in colorectal surgery practice and identify predictors of ERAS utilization. METHODS: A survey of general surgeons identified using the Ontario College of Physicians and Surgeons database was conducted. Information on basic demographic characteristics, utilization of ERAS and predictors of ERAS implementation was collected. Nine ERAS behaviours were analyzed. Multivariable analysis was used to determine effects of demographic, hospital and surgeon covariates on ERAS utilization. RESULTS: Seven hundred and ninety-seven general surgeons were invited to participate in the survey, and 235 general surgeons representing 84 Ontario hospitals responded (30% response rate). Surgeons practising in academic settings and in large community hospitals represented 30% and 47% of the respondents, respectively. A total of 20% of the respondents used all 9 ERAS behaviours consistently. Rates of diet advancement on postoperative day 0, intravenous fluid restriction and having catheter and line procedures were significantly higher among respondents who adhered to ERAS protocols than among those who did not (74% v. 54%, p = 0.004; 92% v. 80%, p = 0.01; and 91% v. 41%, p < 0.001, respectively). Respondents from academic settings reported practising nearly 1 more ERAS behaviour than those from small community hospitals (odds ratio [OR] 0.86, 95% confidence interval [CI] 0.42 to 1.31, p < 0.001). Multivariable analysis demonstrated that colorectal fellowship training or exposure to ERAS during training did not significantly affect ERAS behaviour utilization (OR 0.32, 95% CI -0.31 to 0.94, p = 0.16; OR 0.28, 95% CI -0.26 to 0.82, p = 0.16, respectively). CONCLUSION: Substantial practice variation in colorectal surgery still exists. Individual ERAS principles are commonly followed; however, ERAS behaviours are not widely formalized into hospital protocols.

RESUMO

SUMMARY: Small surgical residency programs like plastic surgery can be challenging environments to accommodate parental leave. This study aimed to report the experiences, attitudes and perceived support of Canadian plastic surgery residents, recent graduates and staff surgeons with respect to pregnancy and parenting during training. Residents and staff surgeons were invited via email to participate in an online survey. The results presented here explore experiences of pregnancy and parental leave of current plastic surgery residents and staff surgeons. Residents' and staff surgeons' perceptions of program director support, policies, negative comments and the impact of parental leave on the workload of others were also explored. Although the findings suggest that there may be improvements in the support of program directors, there continues to be a negative attitude in surgical culture toward pregnancy during residency. The perceived confusion of respondents with respect to programspecific policies emphasizes the need for open conversations and standardization of parental leave.

RESUMO

BACKGROUND: The scope of practice of general surgeons in Canada is highly variable. The objective of this study was to examine the demographic characteristics of general surgeons in Canada and compare surgical procedures performed across community sizes and specialties. METHODS: Data from the Canadian Institute for Health Information's National Physician Database were used to analyze fee-for-service (FFS) care provided by general surgeons and other providers across Canada in 2015/16. RESULTS: Across 8 Canadian provinces, 1669 general surgeons provided FFS care. The majority of the surgeons worked in communities with more than 100 000 residents (71%), were male (78%), were aged 35-54 years (56%) and were Canadian medical graduates (76%). Only 7% of general surgeons practised in rural areas and 14% in communities with between 10 000 and 50 000 residents. Rural communities were significantly more likely to have surgeons who were international medical graduates or who were older than 65 years. The surgical procedures most commonly performed by general surgeons were hernia repairs, gallbladder and biliary tree surgery, excision of skin tumours, colon and intestine resections and breast surgery. Many general surgeons performed procedures not listed in their Royal College of Physicians and Surgeons of Canada training objectives. CONCLUSION: Canadian general surgeons provide a wide array of surgical services, and practice patterns vary by community size. Surgeons practising in rural and small communities require proficiency in skills not routinely taught in general surgery residency. Opportunities to acquire these skills should be available in training to prepare surgeons to meet the care needs of Canadians.

RESUMO

Though overt sexism is decreasing, women now experience subtle, often unconscious, gender bias as microaggressions. The authors sought to explore the prevalence and impact of the sexist microaggressions female surgeons experience, using a sequential exploratory mixed methods approach (January 2018-April 2018), to identify opportunities for education and prevention. First, all resident, fellow, and attending female surgeons at the University of New Mexico Health Sciences Center (UNM HSC) were invited to participate in focus groups conducted by experienced moderators using a semistructured interview guide based on the 7 Sexist Microaggressions Experiences and Stress Scale (Sexist MESS) domains. Qualitative analysis was performed using line-by-line manual coding to identify themes aligned with the Sexist MESS domains as well as other gender bias experiences of female surgeons. Next, a survey was sent to all resident, fellow, and attending female surgeons at the UNM HSC, which included the Sexist MESS questionnaire and questions related to surgeon-specific experiences of gender bias that the authors developed based on major thematic categories from the focus groups.Four focus groups of 23 female surgeons were conducted, revealing 4 themes: exclusion, increased effort, adaptation, and resilience to workplace slights. The survey response rate was 64% (65/101 surgeons). Across Sexist MESS domains, the frequency and severity of microaggressions was higher for trainees than attendings. The variables of non-White race/ethnicity, having children under 18, and fellowship training generally did not demonstrate statistical significance. This exploratory study adds to the growing body of evidence that gender bias in surgery continues and frequently manifests as microaggressions. Trainees reported the highest rates and severity of microaggressions and bias experiences. Further research should investigate how to address microaggressions, the experiences of male surgeons, the perspectives of medical students and groups who were reported as often perpetuating gender bias, and the efficacy of possible interventions.

RESUMO

The clinical outcome of laparoscopic radical prostatectomy (LRP) was retrospectively investigated taking into consideration the surgeon's position during the procedure. The study cohort included 184 consecutive patients who had undergone LRP performed by a single surgeon from February 2013 to July 2018. During the study period,the surgeon stood alternately on either the left or right side of the patient. The D'Amico risk classification was low,intermediate and high in 26 (14.1%),45 (24.5%) and 113 (61.4%) patients,respectively. Mean surgical duration was 203.5 minutes and mean estimated blood loss was 437.6 ml. Nerve sparing (NS) was implemented in 82 (44. 6%) patients. The mean period of having an indwelling urethral catheter was 5. 0 days. Perioperative Clavien-Dindo degree ≥IIIa complications occurred in three (1.6%) patients. Except for cases with presurgical hormonal treatment,surgical margins were positive in 41 (22.3%) patients,among whom 23 (17.4%) had pT2 disease. The 5-year biochemical recurrence-free survival rate was 81.4%,and 84.8% of patients regained urinary continence at 12 months after surgery. Where the surgeon stood during LRP was not associated with significant differences in any parameter. However,the margin positive rate was higher on the side away from where the surgeon stood than the side closer to the surgeon (70.7% vs 29.3%). In conclusion,the position of the surgeon during LRP does not influence the outcome.

RESUMO

The National Health Service (NHS) has rapidly adopted telemedicine solutions as an alternative to face-to-face consultations during the COVID-19 pandemic. The majority of HCPs (Healthcare Professionals) were unfamiliar with Telemedicine prior to the current pandemic. Remote consultation is expected to continue for the foreseeable future, thus we designed this survey. A survey designed to evaluate the use of telephone consultation by HCPs, assessing its implementation, challenges and drawbacks. A web link survey conducted through SurveyMonkey was sent to HCPs across six UK Trusts the period of May 2020. The survey received 114 responses (84%) being doctors. 95% of respondents had not received training prior to engaging in telemedicine consultations. 64% were unaware of the updated General Medical Council guidance concerning remote consultations. The most common barrier in remote consultation was the inability to access patient records raised by 37% of respondents. However, 73% of respondents felt that patients understood their medical condition and the instructions given to them over the phone, and 70% agreed that videoconference consultations would add to patients care. Telemedicine can be used for selected groups of patients in the post COVID-19 era, and the HCPs carrying that should have the sufficient experience and knowledge expected to operate these clinics.

RESUMO

OBJECTIVES: The purpose of this study was to assess the impact of the COVID-19 pandemic on orthopedic and trauma surgery in private practices and hospitals in Germany. DESIGN: In this cross-sectional study, an online-based anonymous survey was conducted from April 2th to April 16th 2020. SETTING: The survey was conducted among 15.0000 of 18.000 orthopedic and trauma surgeons in Germany, both in private practices and hospitals. PARTICIPANTS: All members of the German Society of Orthopedic and Trauma Surgery (DGOU) and the Professional Association for Orthopedic and Trauma Surgery (BVOU). were invited by e-mail to participate in the survey. MAIN OUTCOME MEASURES: Out of 50 questions 42 were designed to enquire a certain dimension of the pandemic impact and contribute to one of six indices, namely "Preparedness", "Resources", "Reduction", "Informedness", "Concern", and "Depletion". Data was analyzed in multiple stepwise regression, aiming to identify those factors that independently influenced the indices. RESULTS: 858 orthopedic and trauma surgeons participated in the survey throughout Germany. In the multiple regression analysis, being employed at a hospital was identified as an independent positive predictor in the indices for "Preparedness", "Resources", and "Informedness" and an independent negative predictor regarding "Depletion". Self-employment was found to be an independent positive predictor of the financial index "Depletion". Female surgeons were identified as an independent variable for a higher level of "Concern". CONCLUSIONS: The study confirms a distinct impact of the COVID-19 pandemic on orthopedic and trauma surgery in Germany. The containment measures are largely considered appropriate despite severe financial constraints. A substantial lack of personal protective equipment (PPE) is reported. The multiple regression analysis shows that self-employed surgeons are more affected by this shortage as well as by the financial consequences than surgeons working in hospitals. WHAT ARE THE NEW FINDINGS: The COVID-19 pandemic has a profound impact on orthopedic and trauma surgery as an unrelated specialty. Self-employed surgeons are affected especially by a shortage of PPE and financial consequences. HOW MIGHT IT IMPACT ON CLINICAL PRACTICE IN THE NEAR FUTURE: Political and financial support can now be applied more focused to subgroups in the field of orthopedics and trauma surgery with an increased demand for support. A special emphasis should be set on the support of self-employed surgeons which are a more affected by the shortage of PPE and financial consequences than surgeons working in hospitals.

RESUMO

BACKGROUND: COVID-19 has become a global pandemic with a dramatic impact on healthcare systems. Concern for viral transmission necessitates the investigation of otologic procedures that use high-speed drilling instruments, including mastoidectomy, which we hypothesized to be an aerosol-generating procedure. METHODS: Mastoidectomy with a high-speed drill was simulated using fresh-frozen cadaveric heads with fluorescein solution injected into the mastoid air cells. Specimens were drilled for 1-minute durations in test conditions with and without a microscope. A barrier drape was fashioned from a commercially available drape (the OtoTent). Dispersed particulate matter was quantified in segments of an octagonal test grid measuring 60 cm in radius. RESULTS: Drilling without a microscope dispersed fluorescent particles 360 degrees, with the areas of highest density in quadrants near the surgeon and close to the surgical site. Using a microscope or varying irrigation rates did not significantly reduce particle density or percent surface area with particulate. Using the OtoTent significantly reduced particle density and percent surface area with particulate across the segments of the test grid beyond 30 cm (which marked the boundary of the OtoTent) compared with the microscope only and no microscope test conditions (Kruskall-Wallis test, p = 0.0066). CONCLUSIONS: Mastoidectomy with a high-speed drill is an aerosol-generating procedure, a designation that connotes the potential high risk of viral transmission and need for higher levels of personal protective equipment. A simple barrier drape significantly reduced particulate dispersion in this study and could be an effective mitigation strategy in addition to appropriate personal protective equipment.
