RESUMO

BACKGROUND: The anterolateral thigh (ALT) perforator flap is a workhorse flap for tongue reconstruction. The authors present an alternative option using the profunda artery perforator (PAP) flap for glossectomy reconstruction compared to the ALT flap. METHODS: A retrospective review was conducted of 65 patients who underwent subtotal or total glossectomy reconstruction between 2016 and 2020 (46 ALT vs. 19 PAP flaps). Flap volume was assessed using CT scans at two different time points. Quality of life and functional outcomes were measured using the MD Anderson Symptom Inventory for head and neck cancer (MDASI-HN). RESULTS: Patients undergoing a PAP flap had significantly lower BMI compared to ALT flaps (22.7±5.0 vs. 25.8±5.1; p=0.014). Donor site and recipient site complications were similar as was the mean flap volume seven months after surgery (30.9% for ALT vs. 28.1% for PAP; p=0.93). Radiation and chemotherapy did not appear to have a significant effect on flap volume change over time. The most frequently reported high-severity items in MDASI-HN were swallowing/chewing and voice/speech for both cohorts. Patients who had reconstruction with a PAP flap had significantly better swallowing function (p=0.034). CONCLUSION: Both the PAP and ALT flaps appear to be safe and effective choices for subtotal and total tongue reconstruction. The PAP flap can serve as an alternative donor site, especially in the setting of malnourished patients with thin lateral thigh thickness undergoing reconstruction of extensive glossectomy defects.

RESUMO

OBJECTIVES: This systematic review seeks to understand whether cold intolerance (CI) improves with time and if there is any role for management strategies such as behavioural therapy, surgery, or pharmacotherapy. METHODS: Two independent reviewers used a predefined search strategy to query MEDLINE, PubMed, Embase, CINAHL, Cochrane Library, Web of Science and Google Scholar databases. Articles written in English, Studies of interventions (such as pharmacotherapy or behavioural therapy) for cold intolerance in adult patients with a history of hand injury along with prevalence over time were included for review. RESULTS: Seventeen studies were included, with twelve prognostic studies of the effect of time on CI, four studies of self management/behavioural therapies, and a single study of surgical treatment of neuromas. No studies of pharmacotherapies were identified for inclusion in the hand injury literature. Most studies (76.4%) were either prevalence or prospective cohort studies; no level I or II evidence studies were included. CONCLUSIONS: Cold intolerance does not resolve over time for the vast majority of patients. Behavioral and self-management studies have low efficacy and studies presented had a high risk of bias. There is a lack of evidence for the use of pharmacotherapy in CI and this could be considered for future studies.

RESUMO

BACKGROUND: Neighborhood-level factors have been shown to influence surgical outcomes through material deprivation, psychosocial mechanisms, health behaviors, and access to resources. To date, no study has examined the relationship between area-level deprivation (ADI) and post-mastectomy outcomes. METHODS: A cross-sectional survey of adult female breast cancer patients who underwent lumpectomy or mastectomy between January 2018 to June 2019 was carried out. Patient-specific characteristics and ADI information were abstracted and correlated with postoperative global- (SF-12) and condition-specific (BREAST-Q) quality-of-life performance via multivariable regression. Patients were classified into three ADI terciles: 0-39 (low deprivation), 40-59 (moderate deprivation), and 60-100 (high deprivation). RESULTS: A total of 564 consecutive patients were identified, being mostly white (75%) with mean age of 60.2 ± 12.4 years, median body mass index of 27.8 [interquartile range (IQR) 24.3-32.2) kg/m2, median Charlson Comorbidity Index of 3 (IQR 2-5), and mean ADI of 42.3 ± 25.7. African American and Hispanic patients and those with high BMI were more likely to reside in highly deprived neighborhoods (p = 0.003 and p < 0.001). In adjusted models, patients in highly deprived neighborhoods had significantly lower mean SF-12 physical (44.9 [95% CI, 43.8-46.0] versus 44.9 [95% CI, 43.7-46.1] versus 46.3 [95% CI, 45.3-47.3], p = 0.03) and BREAST-Q psychosocial well-being scores (63.5 [95% CI, 59.32-67.8] versus 69.3 [95% CI, 65.1-73.6] versus 69.7 [95% CI, 66.4-73.1], p = 0.01) relative to moderate- and low-deprivation groups. CONCLUSIONS: Patients residing in the most deprived neighborhoods were identified to have worse psychological well-being and quality-of-life. The ADI should be incorporated into the shared decision-making process and perioperative counseling to engender value-based and personalized care, especially for vulnerable populations.

RESUMO

BACKGROUND: The cost effectiveness of combining vascularized lymph node transfer (VLNT) with autologous breast reconstruction has not been established. Herein we describe the use of Markov modeling to evaluate the cost utility of VLNT with delayed autologous breast reconstruction for patients with breast cancer related lymphedema (BCRL). METHODS: We conducted a cost effectiveness analysis using a Markov model with microsimulation. The characteristics and associated life expectancy of the hypothetical patients were derived from the Surveillance, Epidemiology, and End Results database. Costs of were derived from the publicly available sources and health economics literature. The utilities were based on the best available literature. The relative effectiveness of VLNT was derived from a meta-analysis of the literature. A specific strategy is considered attractive if the estimate of incremental cost effectiveness ratio (ICER) is less than the amount decision makers are willing to pay for an additional quality-adjusted life-year (QALY) gain. A baseline willingness to pay of $50,000 USD per additional QALY was used for analysis. RESULTS: The base case situation demonstrated an overall ICER of $13898.76/QALY for adding VLNT to delayed autologous abdominally based breast reconstruction in the situation where lymphedema is already present, which suggests it is cost-effective at the chosen willingness to pay. DISCUSSION: This cost-utility simulation demonstrates that it is cost effective to combine delayed breast reconstruction with VLNT in patients with existing lymphedema. This could have implications for the application of the evolving technique of VLNT in the treatment of different subpopulations of breast cancer patients, and future clinical research.

RESUMO

BACKGROUND: Large chest wall resections can result in paradoxical chest wall movement leading to prolonged ventilator dependence and major respiratory impairment. The purpose of this study was to determine as to which factors are predictive or protective of complications in massive oncologic chest wall defect reconstructions. METHODS: A retrospective review of a prospectively maintained database of consecutive patients who underwent immediate reconstruction of massive thoracic oncologic defects (≥5 ribs) was performed. Univariate and multivariate logistic regression analyses identified risk factors. RESULTS: We identified 59 patients (median age, 53 years) with a mean follow-up of 36 months. Rib resections ranged from 5 to 10 ribs (defect area, 80-690 cm2). Sixty-two percent of the patients developed at least one postoperative complication. Superior/middle resections were associated with increased risk of general and pulmonary complications (71.4% vs. 35.3%; OR 4.54; p = 0.013). The 90-day mortality rate following massive chest wall resection and reconstruction was 8.5%. Two factors that were significantly associated with shorter overall survival time were preoperative XRT and preoperative chemotherapy (p = 0.021 and p < 0.001, respectively). CONCLUSIONS: Patients with massive oncological thoracic defects have a high rate of reconstructive complications, particularly pulmonary, leading to prolonged ventilator dependence. Superior resections were more likely to be associated with increased pulmonary and overall complications. The length of postoperative recovery was significantly associated with the size of the defect, and larger defects had prolonged hospital stays. Because of the large dimensions of chest wall defects, almost half of the cases required flap coverage to allow for appropriate defect closure. Understanding the unique demands of these rare but challenging cases is critically important in predicting patient outcomes.

RESUMO

BACKGROUND: Distress among newly diagnosed patients with breast cancer is common and may have an impact on their surgical decision-making. The revised Edmonton Symptom Assessment System (ESAS-r) is a validated instrument that provides an estimate of patients' total distress, and no previous study has related preoperative scores to the choice to have breast reconstruction. METHODS: Women with breast cancer treated at the Princess Margaret Cancer Centre in 2014 were reviewed, and patient and tumor characteristics were collected from local databases. Breast reconstruction status was obtained from patients' electronic medical records until April 2017. A multivariable logistic regression model assessed for an independent association between preoperative ESAS-r total distress scores and patients' decision to have breast reconstruction. RESULTS: A total of 312 patients were analyzed. ESAS-r values had an overall median score of 10.0 and ranged from 0 to 69 (interquartile range, 17). Of these patients, 82 chose to undergo breast reconstruction surgery (26.8%). Multivariable logistic regression analysis showed that higher ESAS-r scores were associated with patients forgoing breast reconstruction surgery (lumpectomy-alone group: odds ratio estimate, 1.034 [1.004-1.064], P = 0.025; mastectomy-alone group: odds ratio estimate, 1.031 [1.004-1.059], P = 0.023). CONCLUSIONS: This study of patients with breast cancer found that higher distress scores as measured by the ESAS-r were associated with reduced breast reconstruction. Distress in patients with breast cancer is important to address, as it is often treatable, and its resolution may unmask a desire for breast reconstruction, which has known benefits psychosocially.

RESUMO

BACKGROUND: Smiling is a fundamental component of social interactions. Significant challenges arise for patients with facial palsy. One of the key procedures for dynamic smile restoration is the microneurovascular transfer of a gracilis muscle. We aimed to assess the effectiveness and safety of dynamic smile reanimation surgery using the free gracilis muscle unit in patients with facial palsy. METHODS: We conducted a systematic review and meta-analysis of studies reporting surgical outcomes of dynamic smile restoration using free gracilis muscles identified from EMBASE, Medline, and Web of Science databases from their inception to March 15, 2018. Two-stage screening and data extraction were performed by two independent reviewers. Pooled proportions were calculated using random-effects models. RESULTS: Thirty-one studies including 1647 patients who underwent 1739 free gracilis flaps were included. Twelve (38.7%) studies measured perioperative smile excursion change using six different tools. Six of these studies were homogeneous and were used in meta-analyses of smile excursion improvement, which revealed a mean change of 7.5 mm (95% CI 6.0-9.0 mm, I2 86.7%) perioperatively. Twenty (64.5%) studies reported perioperative complications, and pooled proportions of flap failures were of 2.9% (95% CI 1.3-4.5%, I2 47.7%). CONCLUSIONS: Dynamic smile restoration using a free gracilis muscle may represent an effective procedure to regain oral commissure motion and is associated with an approximately 3% rate of flap failure. Masseteric nerve coaptations lead to larger improvements in perioperative smile excursion (10 mm) than cross-facial nerve grafts (6.8 mm). Future studies with homogeneous reporting of smile excursion and patient-reported outcome measures are needed.

RESUMO

Health literacy is the extent to which patients are able to understand and act upon health information. This concept is important for surgeons as their patients have to comprehend the nature, risks and benefits of surgical procedures, adhere to perioperative instructions, and make complex care decisions about interventions. Our review aimed to determine the prevalence of limited health literacy of the surgical patient population. A search of MEDLINE and EMBASE was performed from inception until January 14th 2017 for experimental and observational studies reporting surgical patients' health literacy measurement. Overall pooled proportion of surgical patients with limited health literacy was calculated using a random-effects model and methodologic quality was assessed. A total of 40 studies representing 18,895 surgical patients were included in our quantitative synthesis. Pooled estimate of limited health literacy was 31.7% (95%CI 24.7-39.2%, I2 99.0%). There was low risk of bias among the majority of the 51 studies included in the qualitative synthesis. Statistical heterogeneity could not be fully accounted for by methodologic quality or patient and surgical characteristics. However, some of the heterogeneity was accounted by measurement tool [combined proportions with the REALM and NVS of 35.6 (95%CI 31.5-39.9, I2 73.0%)]. A number of different health literacy measurement tools were used (19 overall). Our review demonstrates a high prevalence of limited health literacy among surgical patients with considerable heterogeneity. Our findings suggest the importance of recognizing and addressing surgical patients with limited health literacy and the need for standardization in measurement tools.

RESUMO

BACKGROUND: Unilateral coronal craniosynostosis is a challenging condition in craniofacial surgery. Frontoorbital advancement by single-stage resorbable remodeling and distraction osteogenesis (DO) techniques have known intraoperative differences, but their comparative outcomes are less well characterized. METHODS: A systematic literature search of the MEDLINE, EMBASE, LILACS, and Web of Science databases was conducted. The search was performed using terms related to craniosynostosis and its operative management. The primary outcome of interest was the Whitaker classification. Secondary outcomes included cranial volume or cranial index change, and infection and reoperation rates. RESULTS: A total of 6978 eligible articles were identified of which 26 met inclusion criteria. A total of 292 patients were included in the studies, with 223 undergoing a single-stage remodeling procedure (76.4%) and 69 DO procedures (23.6%). There was a trend toward patients with DO having better Whitaker aesthetic outcomes. Only 2 studies reported volumetric changes. There was a substantial difference in planned and unplanned reoperation rates but not in infection rates. CONCLUSION: The results of this systematic review suggest that the techniques have similar outcomes and complications, although there was a trend toward better Whitaker outcomes with DO procedures. Inherent to the DO technique is the need for multiple operations to both insert and remove internal hardware which may affect the overall cost effectiveness.

RESUMO

PURPOSE: Surgeons and resident physicians in a clinic setting often visually estimate Dupuytren flexion contractures of the hand to follow disease progression and decide on management. No previous study has compared visual estimates with a standardized instrument to ensure measurement reliability. METHODS: Consecutive patients consulted for Dupuytren flexion contractures of the hand had individual joint contractures estimated in degrees (°) by both a resident physician and staff surgeon. Estimates were compared with goniometer measurements to generate intraclass correlation coefficients (ICCs), and residents and surgeons were compared based on their accuracy. RESULTS: Twenty-eight patients enrolled in this study, which provided a total of 80 hand joints for analysis. Resident physicians achieved an ICC of 0.42, which indicates poor reliability. The hand surgeon achieved an ICC of 0.86, which indicates high reliability. The surgeon also had better accuracy than the residents. CONCLUSION: Hand surgeons should be mindful of the limitations of visual estimates of Dupuytren flexion contractures, particularly when conducted by trainees. Joint angle measurements taken for the purposes of research should be done with a goniometer at minimum.


OBJECTIFS: Les chirurgiens et les résidents en milieu clinique font souvent une évaluation visuelle des contractures de Dupuytren pour suivre l'évolution de la maladie et prendre des décisions thérapeutiques. Aucune étude n'a comparé les évaluations visuelles à un instrument standardisé pour garantir la fiabilité de la mesure. MÉTHODOLOGIE: Des patients consécutifs qui avaient consulté en raison de contractures de Dupuytren avaient des contractures articulaires individuelles qu'un résident et un plasticien ont évaluées en degrés. Les auteurs ont ensuite comparé les résultats à des mesures goniométriques pour produire des coefficients de corrélation intraclasse (CCI), puis ont comparé la précision des résidents à celle des plasticiens. RÉSULTATS: Vingt-huit patients ont participé à l'étude, pour un total de 80 articulations de la main pouvant être analysées. Les résidents ont obtenu un CCI de 0,42, ce qui fait foi d'une faible fiabilité. Le plasticien de la main a obtenu un CCI de 0,86, ce qui est indicateur d'une fiabilité élevée. Les résultats du plasticien étaient également plus précis que ceux des résidents. CONCLUSION: Les plasticiens de la main devraient être conscients des limites des évaluations visuelles des contractures de Dupuytren, particulièrement lorsqu'elles sont effectuées par des stagiaires. À tout le moins, il faudrait utiliser un goniomètre pour effectuer les mesures d'angle des articulations obtenues aux fins de la recherche.

RESUMO

PURPOSE: To determine the role of night orthosis use after surgical correction of Dupuytren contracture. METHODS: We searched MEDLINE, EMBASE, CINAHL, AMED, OTSeeker, and CENTRAL for articles published from inception of the databases to August 2015. Assessment was undertaken by 2 independent reviewers (O.A.S. and S.A.). Methodological quality of randomized controlled trials was assessed using the Cochrane risk of bias tool and the Newcastle-Ottawa instrument. RESULTS: Seven studies met the standard for inclusion in this review. A total of 659 patients across these 7 studies were included in the analysis, with follow-up ranging from 3 to 72 months. None of the included studies assessed recurrence. The analysis revealed no significant improvement in range of motion of hand joints for patients who received a static night orthosis after Dupuytren surgery compared with patients without an orthosis. Similarly, no differences were found in patient-reported functional status across the 2 groups. CONCLUSIONS: The current literature does not appear to support the use of static night orthosis in addition to hand therapy after surgical correction of Dupuytren contracture. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

RESUMO

BACKGROUND: Our aim was to determine whether the thoracodorsal (Td) vessels have comparable clinical outcomes to the internal mammary (IM) vessels as recipients for autologous free tissue transfer for breast reconstruction. METHODS: Systematic searches of MEDLINE, EMBASE, CENTRAL, and World of Science from inception to June 2016 were performed by two independent reviewers. Studies that included adult females undergoing autologous free tissue transfer for breast reconstruction were selected. The two comparison groups were the use of IM or Td as recipient vessels. Our primary outcome was rate of flap survival. We assessed the methodologic quality of included studies using the JADAD and MINOR scales. RESULTS: A total of 1897 patients underwent 2644 free abdominal flap tissue transfer in the 10 articles that were included in our analysis. There was one randomized controlled study (Jadad score 2/5) and 9 nonrandomized controlled studies (MINORS scores 11-19/24). There was no difference between the uses of either vessel in terms of flap loss (1.18; 95% CI 0.71-1.95). Complication rate among the IM vessels ranged from 5 to 12%, compared with 3.4-12% among Td vessels. Hematoma and seroma rates were variable. Fat necrosis was higher with Td vessels in two studies. Performing Td vessels anastomosis was associated with shorter operative time and higher risk of encountering unusable vessel. CONCLUSION: Both recipient vessels are safe, reliable and demonstrate equivocal results in the absence of contraindications. Utilizing either as a first-line vessel is reasonable, depending on surgeons' preference or certain clinical scenarios. QUESTION: Therapeutic, Level of evidence: III.

RESUMO

BACKGROUND: Brachial plexus birth palsy (BPBP) affects approximately 1.5 in 1000 live births and can lead to significant functional impairment and reduced quality of life. To date, studies have focused on grading motor function and strength to assess patient outcomes, with less attention paid to sensory recovery. The authors aimed to systematically review the current literature on sensory outcomes following BPBP. METHODS: A systematic review of the best evidence available assessing sensory outcomes following BPBP was conducted. Two independent reviewers used a predefined search strategy to query Cochrane, MEDLINE, EMBASE, and Web of Science databases. Articles written in English reporting sensory outcomes in patients with BPBP, such as tactile sensation, pain, and proprioception, were included for review. A kappa score was calculated to ensure reviewer agreement. RESULTS: Twenty-nine reports with 1647 cases were included. Tactile sensation was most frequently assessed (75.9%), followed by pain (44.8%) and proprioception (17.2%). Among all cases included in the analysis, 75.8% of articles were found to have patients with suboptimal results in sensory outcomes. The majority of articles (86.2%) were case series or case reports; no level 1 or 2 evidence studies were identified. CONCLUSION: Sensory outcomes are underreported following BPBP, and significant deficits and neuropathic pain are not uncommon and likely underappreciated in this patient population. The current report underscores the need for prospective studies that look beyond motor recovery alone and evaluate sensory outcomes following BPBP.

RESUMO

BACKGROUND: Intramedullary (IM) fixation has been described as a reliable method of treatment for certain fracture patterns but has not been widely adopted into practice. The purpose of this study was to evaluate the literature comparing IM fixation to other forms of treatment for metacarpal fractures. METHODS: A systematic review was performed to identify studies investigating the treatment of metacarpal fractures using IM fixation. Inclusion and exclusion criteria were predetermined. Two reviewers independently identified appropriate articles for review based on the criteria. Primary outcome measures were range of motion (ROM) (Styf et al., Rev Chir Orthop Reparatrice Appar Mot 74(Suppl 2):268-270, 2008) and complications. Secondary outcomes included loss of reduction, grip strength, Disabilities of arm, shoulder and hand (DASH) scores, radiographic measures and pain scores. RESULTS: Eight studies were eligible for review. Studies were of level II-IV evidence, and captured a total of 435 patients. The ROM post-operatively was found to be greater in the IM group in half of the studies. IM fixation trended toward higher complication rates in one study, but no differences were statistically significant. IM fixation fared similarly or superiorly to its competitor in each of the secondary outcomes. A formal meta-regression analysis was not possible given the heterogeneity of studies. CONCLUSIONS: IM fixation may have a role in the treatment of certain metacarpal fractures. No conclusive recommendations can be made based on the available studies included in this literature search. Further study of this technique and its applications using high level evidence is warranted.

RESUMO

In 2002, a patient underwent revision total hip arthroplasty for polyethylene wear. The acetabular cup was well fixed, and it was decided to cement a new polyethylene liner into the existing cup. In 2006, the patient presented with inability to weight bear and easy subluxation of the hip. Revision surgery was performed, and all components were examined postoperatively. Investigation with microcomputed tomography revealed that the liner had plastically deformed at the superior pole resulting in the hip instability. The reasons for this are suspected to be related to the abducted nature of the original cup and an uneven cement mantle. This report suggests that cementation of polyethylene liners into metal cups has limitations and is not appropriate in all circumstances.
