RESUMO
Background: Trigeminal neuralgia (TN) is a debilitating disease with an annual incidence of approximately 4-27/100,000. In Ontario, over 2000 patients receive interventions for profound pain, including medical and surgical therapies. The global expected cost of these approaches is unknown. This study aims to analyze the cost-effectiveness of one surgical therapy, microvascular decompression (MVD), compared with the best medical therapy (carbamazepine) as first-line therapy. Methods: Costs were gathered from the Canadian Institute for Health Information, Ontario Drug Benefit Formulary, and Ontario Ministry of Health Schedule of Benefits for Physician Services. Academic literature was used to estimate unavailable items. A cost-benefit Markov model was created for each strategy with literature-based rates for annual cycles from years 1 to 5, followed by a linear recurrent cycle from years 6 to 10. Incremental cost-effectiveness ratios (ICERs) were calculated based on the incremental cost in 2022 Canadian Dollars (CAD) per pain-free year. Results: Base case cost per patient was $10,866 at 10 years in the "MVD first" group and $10,710 in the "carbamazepine first" group. Ten-year ICER was $1,104 for "MVD first," with strict superiority beyond this time point. One-way deterministic sensitivity analysis for multiple factors suggested the highest cost variability and ICER variability were due to surgery cost, medication failure rate, and medication cost. Conclusion: Economic benefit is established for a "MVD first" strategy in the Ontario context with strict superiority beyond the 10-year horizon. If a cost-effectiveness threshold of $50,000 per pain-controlled year is used, the benefit is established at 4 years.
RESUMO
BACKGROUND: Infections after elective colorectal surgery remain a significant burden for patients and the healthcare system. Adult studies suggest that the combination of oral antibiotics and mechanical bowel preparation is effective at reducing infections after colorectal surgery. In children, there is limited evidence for either of these practices and the utility of combining oral antibiotics with mechanical bowel preparation remains uncertain. METHODS: This study aims to determine the feasibility of conducting a randomized controlled trial assessing the efficacy of oral antibiotics, with or without mechanical bowel preparation, in reducing the rates of post-operative infection in pediatric colorectal surgery. Participants aged 3 months to 18 years undergoing elective colorectal surgery will be randomized pre-operatively to one of three trial arms: (1) oral antibiotics; (2) oral antibiotics and mechanical bowel preparation; or (3) standard care. Twelve patients will be included in each trial arm. Feasibility outcomes of interest include the rate of participant recruitment, post-randomization exclusions, protocol deviations, adverse events, and missed follow-up appointments. Secondary outcomes include the rate of post-operative surgical site infections, length of hospital stay, time to full enteral feeds, reoperation, readmission, and complications. DISCUSSION: If the results of this trial prove feasible, a multi-center trial will be completed with sufficient power to evaluate the optimal pre-operative bowel preperation for pediatric patients undergoing elective colorectal surgery. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03593252.
RESUMO
BACKGROUND: Cerebellar mutism (CM) is characterized by a significant loss of speech in children following posterior fossa (PF) surgery. The biological origin of CM remains unclear and is the subject of ongoing debate. Significant recovery from CM is less likely than previously described despite rigorous multidisciplinary neuro-rehabilitational efforts. METHODS: A national multi-centered retrospective review of all children undergoing PF resection in four midsized Canadian academic pediatric institutions was undertaken. Patient, tumor and surgical factors associated with the post-operative development of CM were reviewed. Retrospective identification of PF surgery patients including those developing and those that did not (internal control). RESULTS: The study identified 258 patients across the 4 centers between 2010 and 2020 (mean age 6.73 years; 42.2% female). Overall, CM was experienced in 19.5% of patients (N = 50). Amongst children who developed CM histopathology included medulloblastoma (35.7%), pilocytic astrocytoma (32.6%) and ependymoma (17.1%). Intraoperative impression of adherence to the floor of the 4th ventricle was positive in 36.8%. Intraoperative abrupt changes in blood pressure and/or heart rate were identified in 19.4% and 17.8% of cases. The clinical resolution of CM was rated to be complete, significant resolution, slight improvement, no improvement and deterioration in 56.0%, 8.0%, 20.0%, 14.0% and 2.0%, respectively. In the cohort of children who experienced post-operative CM as compared to their no-CM counterpart, proportionally more tumors were felt to be adherent to the floor of the 4th ventricle (56.0% vs 49.5%), intraoperative extent of resection was a GTR (74% vs 68.8%) and changes in heart rate were noted (≥ 20% from baseline) (26.0% vs 15.9%). However, a multiple regression analysis identified only abrupt changes in HR (OR 5.97, CI (1.53, 23.1), p = 0.01) to be significantly associated with the development of post-operative CM. CONCLUSION: As a devastating surgical complication after posterior fossa tumor surgery with variable clinical course, identifying and understanding the operative cues and revising intraoperative plans that optimizes the child's neurooncological and clinical outcome are essential.

OBJECTIVE: To determine whether targeted sampling (TS), which omits biopsy of triple- normal lymph nodes (LNs) on positron emission tomography, computed tomography, and endobronchial ultrasound (EBUS), is noninferior to systematic sampling (SS) of mediastinal LNs during EBUS for staging of patients with early-stage non-small cell lung cancer (NSCLC). METHODS: Patients who are clinical nodal (cN)0-N1 with suspected NSCLC eligible for EBUS based on positron emission tomography/computed tomography were enrolled in this prospective, multicenter trial. During EBUS, all patients underwent TS and then crossed over to SS, whereby at least 3 mediastinal LN stations (4R, 4L, 7) were routinely sampled. Gold standard of comparison was pathologic results. Based on the previous feasibility trial, a noninferiority margin of 6% was established for difference in missed nodal metastasis (MNM) incidence between TS and SS. The McNemar test on paired proportions was used to determine MNM incidence for each sampling method. Analysis was per-protocol using a level of significance of P < .05. RESULTS: Between November 2020 and April 2022, 91 patients were enrolled at 6 high-volume Canadian tertiary care centers. A total of 256 LNs underwent TS and SS. Incidence of MNM was 0.78% in SS and 2.34% in TS, with an absolute difference of 1.56% (95% confidence interval, -0.003% to 4.1%; P = .13). This falls within the noninferiority margin. A total of 6/256 LNs from 4 patients who were not sampled by TS were found to be malignant when sampled by SS. CONCLUSIONS: In high-volume thoracic endosonography centers, TS is not inferior to SS in nodal staging of early-stage NSCLC. This results in change of clinical management for a minority of patients.
RESUMO
Mild traumatic brain injuries (mTBIs) trigger a neuroinflammatory response, which leads to perturbations in the levels of inflammatory cytokines, resulting in a distinctive profile. A systematic review and meta-analysis were conducted to synthesize data related to levels of inflammatory cytokines in patients with mTBI. The electronic databases EMBASE, MEDLINE, and PUBMED were searched from January 2014 to December 12, 2021. A total of 5,138 articles were screened using a systematic approach based on the PRISMA and R-AMSTAR guidelines. Of these articles, 174 were selected for full-text review and 26 were included in the final analysis. The results of this study demonstrate that within 24 hours, patients with mTBI have significantly higher levels of Interleukin-6 (IL-6), Interleukin-1 Receptor Antagonist (IL-1RA), and Interferon-γ (IFN-γ) in blood, compared to healthy controls in majority of the included studies. Similarly one week following the injury, patients with mTBI have higher circulatory levels of Monocyte Chemoattractant Protein-1/C-C Motif Chemokine Ligand 2 (MCP-1/CCL2), compared to healthy controls in majority of the included studies. The results of the meta-analysis also confirmed these findings by demonstrating significantly elevated blood levels of IL-6, MCP-1/CCL2, and Interleukin-1 beta (IL-1ß) in the mTBI population compared to healthy controls (p < 0.0001), particularly in the acute stages (<7 days). Furthermore, it was found that IL-6, Tumor Necrosis Factor-alpha (TNF-α), IL-1RA, IL-10, and MCP-1/CCL2 were associated with poor clinical outcomes following the mTBI. Finally, this research highlights the lack of consensus in the methodology of mTBI studies that measure inflammatory cytokines in the blood, and also provides direction for future mTBI research.
RESUMO
BRIEF ABSTRACT: This is a protocol to assess feasibility of conducting a prospective cohort study comparing local flaps versus skin grafts for surgical excision of skin cancer from the face. INTRODUCTION: Skin cancer is the most common malignancy worldwide and the face is one of the most common locations of occurrence. Surgical excision is the most popular treatment for small lesions of the face. Defects can be reconstructed using local flaps or skin grafts. There is a paucity of literature evaluating outcomes after skin cancer surgery from the patient's perspective using valid measurement tools. The purpose of this study is to assess the feasibility of conducting a prospective observational cohort study. The primary outcomes include recruitment rates, eligibility rate, compliance of intervention and rate of completion of the primary outcome (FACE-Q scales) at 3 months. Secondary outcomes include examining patient characteristic and FACE-Q score differences between local flaps to skin grafts and adverse events. METHODS AND ANALYSIS: This study is a prospective cohort study consisting of an anticipated 30 patients aged ≥18 years. The study population will consist of a consecutive sample of non-melanoma facial skin cancer patients undergoing a skin graft or local flap. Patients will be followed and evaluated with the FACE-Q questionnaire at 2 weeks, 3 months, 6 months and 1 year post-operation. The following criteria will determine success: patients who meet eligibility criteria >70%; recruitment rate >70%; compliance with intervention >90%; rate of completion of full-scale prospective study primary outcome (FACE-Q at 3 months) >80%; retention rate at 6-month follow-up visit >70%. DISCUSSION: The findings of this study will be used to guide the sample size calculation for a future, large-scale prospective study.Trial registration: ClinicalTrials.gov (NCT04842279).

PURPOSE: To determine whether intraoperative adjunctive EVD placement in patients with a posterior fossa tumor (PFT) led to improved surgical, radiographic, and clinical outcomes compared to those who did not receive an EVD. METHODS: Patients were grouped as those who underwent routine intraoperative adjunctive EVD insertion and those who did not at time of PFT resection. Patients who pre-operatively required a clinically indicated EVD insertion were excluded. Comparative analyses between both groups were conducted to evaluate clinical, radiological, and pathological outcomes. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were computed for post-operative outcomes. RESULTS: Fifty-five selected patients were included, 15 who had an EVD placed at the time of PFT resection surgery, and 40 who did not. Children without an EVD did not experience a higher rate of complications or poorer post-operative outcomes compared to those with an EVD placed during resection surgery. There was no significant difference in the degree of gross total resection (p = 0.129), post-operative CSF leak (p = 1.000), and post-operative hemorrhage (p = 0.554) between those with an EVD and those without. The frequency of new cranial nerve deficits post-operatively was higher in those with an EVD (40%) compared to those without (3%, p = 0.001). There was a trend towards more frequently observed post-operative hydrocephalus in the EVD group (p = 0.057). CONCLUSION: The routine use of EVD as an intraoperative adjunct in clinically stable pediatric patients with posterior fossa tumors and hydrocephalus may not be associated with improved radiological or clinical outcomes.

OBJECTIVE: Intracerebral abscess is a life-threatening condition for which there are no current, widely accepted neurosurgical management guidelines. The purpose of this study was to investigate Canadian practice patterns for the medical and surgical management of primary, recurrent, and multiple intracerebral abscesses. METHODS: A self-administered, cross-sectional, electronic survey was distributed to active staff and resident members of the Canadian Neurosurgical Society and Canadian Neurosurgery Research Collaborative. Responses between subgroups were analyzed using the Chi-square test. RESULTS: In total, 101 respondents (57.7%) completed the survey. The majority (60.0%) were staff neurosurgeons working in an academic, adult care setting (80%). We identified a consensus that abscesses >2.5 cm in diameter should be considered for surgical intervention. The majority of respondents were in favor of excising an intracerebral abscess over performing aspiration if located superficially in non-eloquent cortex (60.4%), located in the posterior fossa (65.4%), or causing mass effect leading to herniation (75.3%). The majority of respondents were in favor of reoperation for recurrent abscesses if measuring greater than 2.5 cm, associated with progressive neurological deterioration, the index operation was an aspiration and did not include resection of the abscess capsule, and if the recurrence occurred despite prior surgery combined with maximal antibiotic therapy. There was no consensus on the use of topical intraoperative antibiotics. CONCLUSION: This survey demonstrated heterogeneity in the medical and surgical management of primary, recurrent, and multiple brain abscesses among Canadian neurosurgery attending staff and residents.

BACKGROUND: Chronic subdural hematoma (CSDH) is a common type of intracranial hemorrhage, especially among the elderly, with a recurrence rate as high as 33%. Little is known about the best type of drainage system and its relationship with recurrence. In this study, we compare the use of two drainage systems on the recurrence rate of CSDH. METHODS: We retrospectively analyzed the charts of 172 CSDH patients treated with bedside twist drill craniostomy (TDC) and subdural drain insertion. Patients were divided into two groups: group A (n = 123) received a pediatric size nasogastric tube [NGT]), whereas group B (n = 49) had a drain commonly used for external ventricular drainage (EVD). Various demographic and radiologic data were collected. Our main outcome was recurrence, defined as symptomatic re-accumulation of hematoma on the previously operated side within 3 months. RESULTS: In all, 212 cases of CSDH were treated in 172 patients. The majority of patients were male (78%) and had a history of previous head trauma (73%). Seventeen cases had recurrence, 11 in group A and 6 in group B. The use of antiplatelet and anticoagulation agents was associated with recurrence (p = 0.038 and 0.05, respectively). There was no difference between both groups in terms of recurrence (odds ratio [OR] = 1.42; 95% confidence interval [CI]: 0.49-4.08; p = 0.573). CONCLUSION: CSDH is a common disease with a high rate of recurrence. Although using a drain postoperatively has shown to reduce the incidence of recurrence, little is known about the best type of drain to use. Our analysis showed no difference in the recurrence rate between using the pediatric size NGT and the EVD catheter post-TDC.

We compared the odds of acquiring surgical site infection (SSI) for clean-contaminated colorectal surgeries between intravenous ß-lactam-based prophylaxis (BLP) versus alternative antimicrobial prophylaxis (AAP). We calculated the odds of acquiring an SSI using logistic regression; adjusted odds ratios (ORs) with 95% confidence intervals (CIs) are reported. Increased odds of SSI were detected with AAP versus BLP (OR, 2.15; 95% CI, 1.33-3.50; P = .002).

OBJECTIVE: To explore whether video-based patient decision aids (VBPDAs) for cataract surgery consultation can enhance a patient's decision-making process while upholding safety regulations during the coronavirus disease 2019 (COVID-19) pandemic. DESIGN: Single-centre consecutive case study. PARTICIPANTS: 147 patients, with an average age of 70 years, who came in for a cataract surgery consult were enrolled in this study. METHODS: All patients watched part 1 of the VBPDA outlining the process of cataract surgery and the decisions involved. Patients then underwent cataract surgery consultation with an ophthalmologist. Afterward, if the patient was indicated for surgery, part 2 of the VBPDA was played. At the end of the visit, all patients completed a survey assessing the effects of COVID-19 safety precautions on their appointment. In addition, patients who had gone forward with surgery complete the Decisional Conflict Scale (DCS). RESULTS: For patients proceeding with cataract surgery, the median DCS score was 9.38 (range, 0-54.69, min-max) on a scale from 0 to 100 (low-high decisional conflict). A DCS score <25 indicates low decisional conflict (n = 76, 68.47%) and a score >25 indicates feeling unsure (n = 35, 31.53%). The DCS also can be separated into various subscales: the informed subscale (median = 8.33; min-max = 0-66.67), values subscale (16.67, 0-58.33), support subscale (8.33, 0-50.00), uncertainty subscale (8.33, 0-83.33), and effective decision subscale (0, 0-37.50). CONCLUSION: Our study found VBPDAs to be an effective tool to enhance the patient decision-making process for cataract surgery during the COVID-19 era.

PURPOSE: To characterize the healthcare utilization and clinical characteristics of patients presenting with flashes and/or floaters (F/F) in general emergency service (GES) settings. METHODS: All adults presenting to GESs (emergency departments (EDs) and urgent care centers (UCCs)) with symptoms of F/F in Hamilton, Ontario between Jan. 1 - Dec. 31, 2018 were reviewed. Primary outcome was the proportion of patients presenting to GESs with F/F for which ophthalmology emergency services (OESs) were consulted. Secondary outcomes included features predictive of OES consultation by logistic regression and cost of GES utilization. RESULTS: Of 6590 primary eye-related visits to GESs, 10.4% (687) involved symptoms of F/F. Mean age of patients with F/F was 57 ± 15 years, and 61% were female. Consultation rate to OESs for F/F presentations was 89% (608/687). Logistic regression identified symptoms ≤ 2 weeks (OR 8.0; 95% CI 2.3-28), ≥ 45 years age (OR 2.4; 95% CI 1.4-4.3), UCC setting (OR 2.7; 95% CI 1.6-4.6), headache (OR 0.22; 95% CI 0.12-0.41), and neurologic symptoms (OR 0.1; 95% CI 0.19-0.49) as variables predictive of OES consultation. Mean time from triage to discharge in GESs for F/F patients was 2.43 ± 2.36 h. Mean cost per visit was $139.11 ± $113.93 Canadian dollars. Patients for which OES were consulted waited a total of 1345 h in GESs and accounted for $81,879.70 in costs. CONCLUSION: Patients presenting with F/F in GESs consume considerable resources in healthcare expenditure and time spent in GESs and most receive OES consultation. Identifying these patients at triage may allow for increased efficiency for the healthcare system and patients.

Randomized controlled trials (RCTs) have become the standard method of evaluating new interventions (whether medical or surgical), and the best evidence used to inform the development of new practice guidelines. When we review the history of medical versus surgical trials, surgical RCTs usually face more challenges and difficulties when conducted. These challenges can be in blinding, recruiting, funding, and even in certain ethical issues. Moreover, to add to the complexity, the field of neurosurgery has its own unique challenges when it comes to conducting an RCT. This paper aims to provide a comprehensive review of the history of neurosurgical RCTs, focusing on some of the most critical challenges and obstacles that face investigators. The main domains this review will address are: (1) Trial design: equipoise, blinding, sham surgery, expertise-based trials, reporting of outcomes, and pilot trials, (2) trial implementation: funding, recruitment, and retention, and (3) trial analysis: intention-to-treat versus as-treated and learning curve effect.
RESUMO
Brain abscesses are associated with considerable morbidity and mortality, requiring timely intervention to achieve favourable outcomes. With the advent of high-resolution computed tomography (CT) imaging, mortality following both aspiration and excision of brain abscesses has improved markedly. As a result, there has been a marked shift in neurosurgical practice with aspiration eclipsing excision as the favoured first-line modality for most abscesses. However, this trend lacks sufficient supporting evidence, and this systematic review and meta-analysis seeks to compare aspiration and excision in the treatment of brain abscess. Twenty-seven studies were included in the systematic review, and seven comparative papers in meta-analysis. Aspiration was the chosen technique for 67.5% of patients. Baseline characteristics from the studies included only in the systematic review demonstrated that abscesses treated by aspiration were typically larger and in a deeper location than those excised. In the meta-analysis, we initially found no significant difference in mortality, re-operation rate, or functional outcome between the two treatment modalities. However, sensitivity analysis revealed that excision results in lower re-operation rate. On average, the included studies were of poor quality with average Methodological Index for Non-Randomized Studies (MINORS) scores of 10.3/16 and 14.43/24 for non-comparative and comparative papers respectively. Our study demonstrates that excision may offer improved re-operation rate as compared to aspiration for those abscesses where there is no prior clinical indication for either modality. However, no differences were found with respect to mortality or functional outcome. Evidence from the literature was deemed low quality, emphasizing the need for further investigation in this field, specifically in the form of large, well-controlled, comparative trials.

Background: Despite maximal safe cytoreductive surgery and postoperative adjuvant therapies, glioblastoma (GBM) inevitably recurs and leads to deterioration of neurological status and eventual death. There is no consensus regarding the benefit of repeat resection for enhancing survival or quality of life in patients with recurrent GBM. We aimed to examine if reoperation for GBM recurrence incurs a survival benefit as well as examine its complication profile. Methods: We performed a single-center retrospective chart review on all adult patients who underwent resection of supratentorial GBM between January 1, 2008 and December 1, 2013 at our center. Patients with repeat resection were manually matched for age, sex, tumor location, and Karnofsky Performance Status (KPS) with patients who underwent single resection to compare overall survival (OS), and postoperative morbidity. Results: Of 237 patients operated with GBM, 204 underwent single resection and 33 were selected for repeat surgical resections. In a matched analysis there was no difference in the OS between groups (17.8 ± 17.6 months vs 17 ± 13.5 months, P = .221). In addition, repeat surgical resection had a higher rate of postoperative neurological complications compared to the initial surgery. Conclusions: When compared with matched patients who underwent a single surgical resection, patients undergoing repeat surgical resection did not show significant increase in OS and may have incurred more neurological complications related to the repeat resection. Further studies are required to assess which patients would benefit from repeat surgical resection and optimize timing of the repeat resection in selected patients.
RESUMO
OBJECTIVE: This study analyzed patient, radiologic, and clinical factors associated with operative brain abscesses and patients' functional outcomes. METHODS: A retrospective analysis was conducted of neurosurgical cases of brain abscesses from 2009 to 2019 at a Canadian center. Functional outcome was recorded as Modified Rankin Scale score and Extended Glasgow Outcome Scale score. Multivariate analysis was conducted to identify relevant prognostic factors. RESULTS: We identified 139 patients managed surgically for brain abscesses. Resection alone was performed in 64% of patients, whereas 26.6% underwent aspiration alone. Most were adults (93.2%) and male (68.3%). Immunocompromise risk factors included diabetes (24.5%), cancer (23.7%), and immunosuppressive therapy (11.5%). Likely sources were postoperative (17.3%), systemic spread (16.5%), and poor dentition (12.9%). Microorganisms cultured from abscess samples were mixed growth (28%), Streptococcus anginosus (24.5%), and Staphylococcus aureus (7.9%). Disposition was home (42.4%) or repatriation to a home hospital (50.4%). By Extended Glasgow Outcome Scale, 25.2% had an unfavorable outcome including a mortality of 11.5%. Factors on multivariate analysis associated with poor outcome included diabetes (odds ratio, 2.8; 95% confidence interval [CI], 1.2-5.0) and ventricular rupture (odds ratio, 5.0; 95% CI, 1.7-13.5; hazard ratio, 12; 95% CI, 3.9-37.0). Supratentorial superficial eloquently located abscess was also associated with poor outcome (hazard ratio, 5.5; 95% CI, 1.8-16.7). Outcomes were similar with surgical excision and aspiration. CONCLUSIONS: Ventricular rupture and diabetes are significant risk factors for poor outcomes in intraparenchymal brain abscesses. No clear difference in outcomes was found between surgical excision or aspiration in our retrospective cohort.

INTRODUCTION: Research quality in pediatric surgery has been challenged by multiple factors, including the low incidence of some congenital pathologies and rare event rates. With the rapid increase of pediatric surgical literature, there is a need for systematic reviews to synthesize evidence. It is important to assess the quality of these systematic reviews. OBJECTIVE: This study aims to examine the reporting of systematic reviews and meta-analyses, using inguinal hernia repair as an index diagnosis. METHODS: MEDLINE, Embase, and CINAHL databases were searched for systematic reviews and/or meta-analyses of interventions on inguinal hernia in the pediatric population. The quality reporting was assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and A MeaSurement Tool to Assess Systematic Reviews (AMSTAR) 2 tools. RESULTS: Of 1449 unique reports, 21 studies were included (15 meta-analyses and six systematic reviews). Median percent reported items for PRISMA and AMSTAR 2 were 72.2% and 70.5%, respectively. The least reported items in PRISMA were protocol registration (27.6%), synthesis of results (13.0%), and a risk of bias across studies (20.6%). For AMSTAR 2, the least reported items were reporting of source of funding (14.3%), appropriate methods for statistical combination of results (25.0%), and pre-establishment of protocol (28.6%). All critical items were completely or partially fulfilled in 5/21 (23.8%) of the studies and completely absent in 1/21 (4.8%) studies. CONCLUSIONS: The results of this study highlight relatively good reporting quality, yet a poor methodological quality of systematic reviews/meta-analyses in the pediatric surgery literature on inguinal hernia management.

Objective: Resident wellness is a focus of medical training and is prioritized in both Canadian and American accreditation processes. Job satisfaction is an important component of wellness that is not examined in the literature. The purpose of this study was to analyze job satisfaction in a national sample of plastic surgery residents, and identify factors that influence satisfaction. Methods: We designed a cross-sectional survey adapted from existing instruments, with attention to thorough item generation and reduction as well as pilot and clinical sensibility testing. All plastic surgery residents at Canadian institutions were surveyed regarding overall job satisfaction as well as personal- and program-specific factors that may affect satisfaction. Predictors of satisfaction were identified using multivariable regression models. Results: The response rate was 40%. Median overall job satisfaction was 4.0 on a 5-point Likert scale. Operative experience was considered both the most important element of a training program, and the area in most need of improvement. Senior training year (P < .01), shorter commute time (P = .04), fewer duty hours (P = .02), fewer residents (P < .01), and more fellows (P < .01) were associated with significantly greater job satisfaction. Conclusions: This is the first study to gather cross-sectional data on job satisfaction from a national sample of plastic surgery residents. The results from this study can inform programs in making tangible changes tailored to their trainees' needs. Moreover, our findings may be used to inform a prospectively studied targeted intervention to increase job satisfaction and resident wellness to address North American accreditation standards.
Objectif: Le bien-être des résidents est un point central de la formation en médecine et représente une priorité dans le processus d'agrément canadien et américain. La satisfaction au travail constitue un volet important du bien-être qui n'est pas évalué dans les publications. La présente étude visait à analyser la satisfaction au travail dans un échantillon national de résidents en plasturgie et à déterminer les facteurs qui influent sur la satisfaction. Méthodologie: Les chercheurs ont conçu un sondage transversal adapté d'outils existants, en s'attardant à la production et à la réduction de points approfondis et à un test de sensibilité clinique. Tous les résidents en plasturgie des établissements canadiens ont reçu un sondage sur leur satisfaction au travail et sur les facteurs personnels et propres à leur programme, susceptibles d'influer sur leur satisfaction. Les chercheurs ont déterminé les prédicteurs de satisfaction au moyen de modèles de régression multivariables. Résultats: Le taux de réponse s'élevait à 40%. La satisfaction au travail médiane globale obtenait un résultat de 4,0 sur l'échelle de Likert de cinq points. L'expérience opératoire était considérée à la fois comme l'élément le plus important d'un programme de formation et comme le secteur qui a le plus besoin d'être amélioré. L'année de formation senior (P < .01), une durée de déplacement plus courte (P = .04), un moins grand nombre d'heures de garde (P = .02) et de résidents (P < .01) et un plus grand nombre de boursiers postdoctoraux (P < .01) ont été associés à une satisfaction au travail considérablement plus marquée. Conclusions: C'est la première étude pour colliger des données transversales sur la satisfaction au travail auprès d'un échantillon national de résidents en plasturgie. Les résultats de cette étude peuvent éclairer les programmes pour apporter des changements tangibles adaptés aux besoins de leurs stagiaires. De plus, nos observations pourraient éclairer une intervention prospective ciblée pour accroître la satisfaction au travail et le bien-être des résidents afin de satisfaire aux normes d'agréments nord-américaines.
RESUMO
Purpose: To assess if preoperative angiography of the lower extremity is necessary to detect abnormalities that alter operative planning of a free fibula flap (FFF). The secondary objective is to determine whether abnormalities are identified on physical examination. Methods: A retrospective case series of patients receiving preoperative lower extremity angiography for FFF was performed. Between November 2004 and July 2016, patients assessed for FFF reconstruction by a single surgeon were reviewed. Outcomes analyzed were preoperative physical examination, angiography findings, changes in operative plan, and perioperative complications including flap failure and limb ischemia. Level of agreement between physical examination and angiography findings was analyzed. Results: A total of 132 consecutive patients were assessed for FFF, of which 70 met the inclusion criteria. Mean age was 60.9 (range: 22-88) years old. All patients underwent aortic angiogram runoff, except for 2 who received computed tomography angiography. The surgical plan was altered based on angiography findings in 9 (12.9%) patients, and 7 (77.8%) of these cases had a normal physical examination. A further 6 (8.6%) patients had physical examination findings precluding the use of FFF, whereas imaging demonstrated the contrary. Physical examination demonstrated low predictability of aberrant vascular anatomy, with a sensitivity of 22.2%. There were no limb ischemia complications. Conclusions: Routine preoperative angiography of the lower extremity for all patients being evaluated for FFF is important to ensure safety and success of the procedure. Physical examination alone is insufficient to detect vascular abnormalities that may result in limb or flap compromise.
Objectif: Évaluer s'il faut procéder à une angiographie préopératoire de l'extrémité inférieure pour déceler des anomalies qui perturbent le plan opératoire en vue du prélèvement d'un lambeau libre de la fibula (ou péroné, LLF). L'objectif secondaire consiste à déterminer si des anomalies sont décelées à l'examen physique. Méthodologie: Les chercheurs ont examiné une série rétrospective de cas ayant subi une angiographie préopératoire de l'extrémité inférieure en vue du prélèvement d'un LLF. Ils ont examiné les patients évalués en vue d'une reconstruction par LLF effectuée par un même chirurgien entre novembre 2004 et juillet 2016. Ils ont analysé l'examen physique préopératoire, les résultats de l'angiographie, les modifications au plan opératoire et les complications périopératoires, y compris l'échec du lambeau et l'ischémie du membre. Enfin, ils ont analysé le degré de convergence entre l'examen physique et les résultats de l'angiographie. Résultats: Les chercheurs ont évalué 132 patients en vue du prélèvement d'un LLF, dont 70 respectaient les critères d'inclusion. Ils avaient un âge moyen de 60,9 ans (plage de 22 à 88 ans). Tous les patients ont subi une angiographie aortique détaillée, sauf deux qui ont subi une angiographie par tomodensitométrie. Le plan opératoire a été modifié en raison des observations angiographiques chez neuf patients (12,9 %), et l'examen physique était normal pour sept d'entre eux (77,8 %). Chez six autres patients (8,6 %), l'examen physique écartait le prélèvement du LLF, mais l'imagerie démontrait le contraire. L'examen physique a établi la faible prévisibilité des aberrations de l'anatomie vasculaire, selon une sensibilité de 22,2 %. Aucune complication ischémique des membres n'a été observée. Conclusions: Il est important de procéder à une angiographie préopératoire systématique de l'extrémité inférieure chez tous les patients évalués en vue du prélèvement d'un LLF pour garantir la sécurité et la réussite de l'intervention. L'examen physique seul ne suffit pas pour déceler les anomalies vasculaires susceptibles d'entraîner une atteinte du membre ou du lambeau.
