Mass-like calcific peri-arthritis in the wrist: a rare case presenting as acute carpal tunnel syndrome and requiring surgical intervention.

Hydroxyapatite deposition disease (HADD) is a common localized disorder characterized by deposition of hydroxyapatite in soft tissues. These hydroxyapatite deposits can be found in the periarticular soft tissues such as bursae, joint capsules, tendon sheaths, and ligaments as well as within the tendons themselves, and intra-articular involvement has also been described [1,2]. We present a case of a 50-year-old female with acute symptoms of carpal tunnel syndrome secondary to partially liquified, mass-like, inflammatory calcific peri-arthritis. The case is supplemented with the use of multimodality imaging, a surgical perspective, and histopathologic correlation.

Trainee Operative Autonomy in Plastic Surgery.

BACKGROUND: Appropriate, progressive trainee autonomy is critical for training competent plastic surgeons who are adequately prepared to enter independent practice. Evaluation and reporting of meaningful operative autonomy among trainees in plastic surgery are understudied. METHODS: Parallel survey instruments were developed using the Zwisch metric for progressive operative autonomy and distributed electronically to trainees and faculties in all accredited training programs. Trainees were queried about their operative autonomy in 17 core plastic surgery procedures, associated approach to logging cases, and perceived readiness to enter practice. Faculties provided assessment of their final-year trainees using the same metrics. RESULTS: Trainees in 28 programs and faculties in 35 programs participated. Final-year trainees reported the most operative independence with breast tissue expander reconstruction and carpal tunnel release and the least with facelift and rhinoplasty. A mean of 40% of final-year trainees reached supervision only autonomy in the procedures queried; none achieved this with rhinoplasty. Faculties identified the highest final-year trainee operative autonomy with botulinum toxin injection and burn excision and grafting; the least trainee independence was reported with rhinoplasty, cleft lip repair, and facelift. Faculty perception of final-year trainee autonomy was higher than that of trainees for 82% of procedures queried. CONCLUSIONS: Although plastic surgery trainees endorse gradual operative autonomy overall, a majority of final-year trainees do not perceive supervision only independence in the majority of core procedures queried. Faculties perceive higher trainee operative autonomy than trainees for most procedures. Discordant approaches to case logging were identified both among trainees and between trainees and faculties. Standardization may improve both progression and assessment of operative autonomy in plastic surgery training.

The accessibility, readability, and quality of online resources for gender affirming surgery.

BACKGROUND: The transgender population is disproportionally affected by health disparities related to access to care. In many communities, transgender specialists are geographically distant and locally available medical professionals may be unfamiliar with unique needs of transgender patients. As a result, use of Internet resources for information about gender affirming surgery is particularly important. This study simulates a patient search for online educational material about gender affirming surgery and evaluates the accessibility, readability, and quality of the information. METHODS: An Internet search for the term "transgender surgery" was performed, and the first 10 relevant hits were identified. Readability was assessed using 10 established tests: Coleman-Liau, Flesch-Kincaid, FORCAST, Fry, Gunning Fog, New Dale-Chall, New Fog Count, Raygor Estimate, Simple Measure of Gobbledygook, and Flesch Reading Ease. Quality was assessed using Journal of the American Medical Association criteria and the DISCERN instrument. RESULTS: Review of 69 results was required to identify 10 sites with relevant patient information. There were 97 articles collected; overall mean reading level was 14.7. Individual Web site reading levels ranged from 12.0 to 17.5. All articles and Web sites exceeded the recommended sixth grade level. Quality ranged from 0 to 4 (Journal of the American Medical Association) and 35 to 79 (DISCERN) across Web sites. CONCLUSIONS: Web sites with relevant patient information about gender affirming surgery were difficult to identify from search results. The content of these sites universally exceeded the recommended reading level. A wide range of Web site quality was noted, and this may further complicate successful navigation. Barriers in access to appropriately written patient information on the Internet may contribute to disparities in referral, involvement, satisfaction, and outcomes.

Evaluating the Use of Tissue Oximetry to Decrease Intensive Unit Monitoring for Free Flap Breast Reconstruction.

BACKGROUND: Postoperative free flap care has historically required intensive monitoring for 24 hours in an intensive care unit. Continuous monitoring with tissue oximetry has allowed earlier detection of vascular compromise, decreasing flap loss and improving salvage. This study aims to identify whether a fast-track postoperative paradigm can be safely used with tissue oximetry to decrease intensive monitoring and costs. MATERIALS AND METHODS: All consecutive microsurgical breast reconstructions performed at a single institution were reviewed (2008-2014) and cases requiring return to the operating room were identified. Data evaluated included patient demographics, the take back time course, and complications of flap loss and salvage. A cost-benefit analysis was performed to analyse the utility of a postoperative intensive monitoring setting. RESULTS: There were 900 flaps performed and 32 required an unplanned return to the operating room. There were 16 flaps that required a reexploration within the first 24 hours; the standard length of intensive unit monitoring. After 4 hours, there were 7 flaps (44%) detected by tissue oximetry for reexploration. After 15 hours of intensive monitoring postoperatively, cost analysis revealed that the majority (15/16; 94%) of failing flaps had been identified and the cost of identifying each subsequent failing flap exceeded the cost of another hour of intensive monitoring. CONCLUSIONS: The postoperative paradigm for microsurgical flaps has historically required intensive unit monitoring. Using tissue oximetry, a fast-track pathway can reduce time spent in an intensive monitoring setting from 24 to 15 hours with significant cost savings and minimal risk of missing a failing free flap.

Readability analysis of online resources related to lung cancer.

BACKGROUND: Patients seeking health information commonly use the Internet as the first source for material. Studies show that well-informed patients have increased involvement, satisfaction, and healthcare outcomes. As one-third of Americans have only basic or below basic health literacy, the National Institutes of Health and American Medical Association recommend patient-directed health resources be written at a sixth-grade reading level. This study evaluates the readability of commonly accessed online resources on lung cancer. METHODS: A search for "lung cancer" was performed using Google and Bing, and the top 10 websites were identified. Location services were disabled, and sponsored sites were excluded. Relevant articles (n = 109) with patient-directed content available directly from the main sites were downloaded. Readability was assessed using 10 established methods and analyzed with articles grouped by parent website. RESULTS: The average reading grade level across all sites was 11.2, with a range from 8.8 (New Fog Count) to 12.2 (Simple Measure of Gobbledygook). The average Flesch Reading Ease score was 52, corresponding with fairly difficult to read text. The readability varied when compared by individual website, ranging in grade level from 9.2 to 15.2. Only 10 articles (9%) were written below a sixth-grade level and these tended to discuss simpler topics. CONCLUSIONS: Patient-directed online information about lung cancer exceeds the recommended sixth-grade reading level. Readability varies between individual websites, allowing physicians to direct patients according to level of health literacy. Modifications to existing materials can significantly improve readability while maintaining content for patients with low health literacy.

The Readability of Online Patient Information About Mohs Micrographic Surgery.

BACKGROUND: Mohs micrographic surgery has become increasingly used in the treatment of cutaneous malignancies over the past decade. Concurrently, more patients are using the Internet as a resource for medical information than ever before. The average American adult reads at an eighth grade level. The American Medical Association and National Institutes of Health have recommended a sixth grade target reading level for patient health materials. OBJECTIVE: This study evaluates the readability of currently available online information about Mohs micrographic surgery in the context of these recommendations. METHODS: An Internet search for the term "Mohs surgery" was performed and the first 10 results were identified. Patient information from each primary site was downloaded and formatted into plain text. Readability was assessed using 9 established tests; text was analyzed both overall and by Web site for comparison. RESULTS: A total of 101 articles were collected from the first 10 Web site search results; the overall average reading level was 14.4. All articles exceeded the recommended sixth grade reading level. CONCLUSION: Online resources about Mohs micrographic surgery are too difficult for many patients to read. The paucity of appropriately written patient information available on the Internet may hinder informed decision-making, participation, and subsequent postoperative satisfaction.

The Readability of Online Resources for Mastopexy Surgery.

BACKGROUND: As more patients use Internet resources for health information, there is increasing interest in evaluating the readability of available online materials. The National Institutes of Health and American Medical Association recommend that patient educational content be written at a sixth-grade reading level. This study evaluates the most popular online resources for information about mastopexy relative to average adult literacy in the United States. METHODS: The 12 most popular sites returned by the largest Internet search engine were identified using the search term "breast lift surgery." Relevant articles from the main sites were downloaded and formatted into text documents. Pictures, captions, links, and references were excluded. The readability of these 100 articles was analyzed overall and subsequently by site using 10 established readability tests. Subgroup analysis was performed for articles discussing the benefits of surgery and those focusing on risks. RESULTS: The overall average readability of online patient information was 13.3 (range, 11.1-15). There was a range of average readability scores overall across the 12 sites from 8.9 to 16.1, suggesting that some may be more appropriate than others for patient demographics with different health literacy levels. Subgroup analysis revealed that articles discussing the risks of mastopexy were significantly harder to read (mean, 14.1) than articles about benefits (11.6). CONCLUSIONS: Patient-directed articles from the most popular online resources for mastopexy information are uniformly above the recommended reading level and likely too difficult to be understood by a large number of patients in the United States.

Online Patient Resources for Liposuction: A Comparative Analysis of Readability.

BACKGROUND: As patients strive to become informed about health care, inadequate functional health literacy is a significant barrier. Nearly half of American adults have poor or marginal health literacy skills and the National Institutes of Health and American Medical Association have recommended that patient information should be written at a sixth grade level. The aim of this study is to identify the most commonly used online patient information about liposuction and to evaluate its readability relative to average American literacy. METHODS: An internet search of "liposuction" was performed and the 10 most popular websites identified. User and location data were disabled and sponsored results excluded. All relevant, patient-directed articles were downloaded and formatted into plain text. Articles were then analyzed using 10 established readability tests. A comparison group was constructed to identify the most popular online consumer information about tattooing. Mean readability scores and specific article characteristics were compared. RESULTS: A total of 80 articles were collected from websites about liposuction. Readability analysis revealed an overall 13.6 grade reading level (range, 10-16 grade); all articles exceeded the target sixth grade level. Consumer websites about tattooing were significantly easier to read, with a mean 7.8 grade level. These sites contained significantly fewer characters per word and words per sentence, as well as a smaller proportion of complex, long, and unfamiliar words. CONCLUSIONS: Online patient resources about liposuction are potentially too difficult for a large number of Americans to understand. Liposuction websites are significantly harder to read than consumer websites about tattooing. Aesthetic surgeons are advised to discuss with patients resources they use and guide patients to appropriate information for their skill level.

Intraoperative Hemifacial Composite Flap Perfusion Assessment Using Spatial Frequency Domain Imaging: A Pilot Study in Preparation for Facial Transplantation.

BACKGROUND: Vascularized composite allotransplantation represents an important advancement in the field of reconstructive microsurgery and has continued to increase in popularity. The significant clinical morbidity associated with flap failure represents an important barrier to even more widespread use of these techniques. Early identification of vascular compromise has been associated with a higher salvage rate, yet most surgeons rely only on clinical assessment intraoperatively. Spatial frequency domain imaging (SFDI) presents a noncontact, objective measurement of tissue oxygenation over a large field of view. This study aims to evaluate the use of SFDI technology in hemifacial composite flap compromise as could occur during facial transplant. METHODS: Six composite hemifacial flaps were created in three 35-kg Yorkshire pigs and continuously imaged using SFDI before, during, and after 15-minute selective vascular pedicle occlusion. Arterial and venous clamping trials were performed for each flap. Changes in oxyhemoglobin concentration, deoxyhemoglobin concentration, and total hemoglobin were quantified over time. RESULTS: The SFDI successfully measured changes in oxygenation parameters in all 6 composite tissue flaps. Significant changes in oxyhemoglobin, deoxyhemoglobin, and total hemoglobin were seen relative to controls. Early and distinct patterns of alteration were noted in arterial and in venous compromise relative to one another. CONCLUSIONS: The need for noninvasive, reliable assessment of composite tissue graft viability is apparent, given the morbidity associated with flap failure. The results of this study suggest that SFDI technology shows promise in providing intraoperative guidance with regard to pedicle vessel integrity during reconstructive microsurgery.

Preoperative CT-angiography in autologous breast reconstruction.

BACKGROUND: CT-angiography (CTA) has been introduced as a means of evaluating arterial anatomy and vascular integrity prior to free autologous breast reconstruction. There is limited published data, however, regarding the incidence, indications, and impact of preoperative CTA (pCTA) on procedural and flap outcomes. METHODS: Retrospective review was performed of all autologous microsurgical breast reconstruction procedures at a single academic center between January 2004 and July 2014. Univariate analysis of patient, procedural, and flap characteristics was performed and a logistic regression model was configured to assess for factors associated with ischemia-related complications. RESULTS: There were 1,110 microsurgical flap reconstructions performed in 778 patients by 3 surgeons at our institution during the study period. Overall, 11.4% of patients underwent pCTA; frequency increased from 0 to 35.7%. Patients who underwent pCTA had significantly higher body mass index (P = 0.041), and more coronary artery disease (P = 0.022), prior abdominal surgery (P = 0.004), and bilateral reconstruction (P = 0.015). No statistically significant difference between groups was found with respect to flap characteristics or operative time. Multivariate analysis revealed that although pCTA was associated with a lower incidence of ischemia-related complications (complete or partial flap loss or fat necrosis) (OR, 0.57, 95% CI, 0.32 to 1.02), this did not reach statistical significance (P = 0.058). CONCLUSIONS: Use of pCTA has increased dramatically at our institution since it was first incorporated into the reconstructive surgical planning process in 2008. Given the expense, radiation exposure, and borderline impact on ischemia-related flap complications, surgeons should selectively consider pCTA as an adjunct to their surgical planning algorithm. © 2015 Wiley Periodicals, Inc.

A Novel Free Flap Monitoring System Using Tissue Oximetry with Text Message Alerts.

Background The time to detection of vascular compromise is a significant predictor of free flap salvage outcomes as early reexploration improves salvage rates. Continuous transcutaneous near-infrared tissue oximetry is an objective, quantitative method of detecting flap vascular compromise and has been shown to allow earlier reexploration and higher salvage rates than clinical assessment alone. We designed a novel text messaging system to improve communication using tissue oximetry monitoring. Methods A retrospective review was performed of a prospectively collected database of all microsurgical breast reconstructions from 2008 to 2015. A novel text messaging system was introduced in 2013 and programmed to send text messages alert when the tissue oximetry readings suggested potential flap compromise based on established thresholds. Patient demographics and complications, including rate of reexploration and flap loss were assessed. Results There were 900 autologous microsurgical breast free flaps during the study period: 614 were monitored with standard clinical monitoring and tissue oximetry compared with 286 flaps with the additional text messaging system. There were 27 unplanned returns to the operating room in the tissue oximetry group and 5 in the text messaging group with 1 complete flap loss in each group. Reexploration occurred sooner as a result of these text message alerts (17.5 vs. 26.6 hours postoperatively), however, it did not achieve statistical significance. Conclusions We were able to demonstrate the use of a novel text messaging system for tissue oximetry. This alert system shows promise in identifying impending flap loss with rapid notification of the surgical team.

Assessment of online patient materials for breast reconstruction.

BACKGROUND: Limited health literacy affects nearly half of American adults and adversely affects patient participation, satisfaction, health care costs, and overall outcomes. As patients increasingly search the Internet for health information, accessibility of online material is critical. Previous studies examining this topic have focused on the readability of these materials. This study evaluates online breast reconstruction resources with regard to reading level, however, adds new metrics to assess degree of complexity, and suitability for the intended audience. METHODS: The 10 most popular patient Web sites for "breast reconstruction" were identified using the largest Internet search engine. The content of each site was assessed for readability using the simple measure of gobbledygook analysis, complexity using the PMOSE/iKIRSCH formula, and suitability using the suitability assessment of materials instrument. Resulting scores were analyzed overall and by Web site. RESULTS: Readability analysis revealed an overall average grade level of 13.4 (range 10.7-15.8). All sites exceeded the recommended sixth grade level. Complexity evaluation revealed a mean PMOSE/iKIRSCH score of 6.3, consistent with "low" complexity and requiring an 8th-12th grade education; individual sites ranged from "very low" to "high" complexity. Suitability assessment overall produced a mean 41.2% score, interpreted as "adequate" for the intended patient audience. Five of the 10 sites were found to be "not suitable" when examined individually; the remaining five were "adequate." CONCLUSIONS: Available online patient material for breast reconstruction is often too difficult for many patients to understand based on readability, complexity, and suitability metrics. Comprehensive assessment is needed to design appropriate patient material and minimize disparities related to limited health literacy.

Patient preferences in access to breast reconstruction.

BACKGROUND: Patient access to breast reconstruction is an important component of comprehensive breast cancer care. There is currently considerable variability in the timing of consultation with a plastic and reconstructive surgeon after the initial diagnosis of breast cancer. This study aims to elucidate patients' preferences for the timing of plastic surgery consultation as part of the preoperative evaluation and planning process. METHODS: A 16-question electronic survey instrument was developed based on formative patient comments and discussion between the breast oncology and plastic surgery teams. The survey was administered to all patients referred to the plastic and reconstructive surgery clinic for initial reconstructive consultation during the study period. RESULTS: A total of 31 responses were collected. The largest number of patients (48%) indicated they would prefer to see a plastic surgeon 1 wk after their first consultation with a breast surgeon. Only one patient reported a desire to see both surgeons on the same day. Most patients indicated that having a family member or friend accompany them to the appointment (45%) and having time to process their cancer diagnosis before seeing the plastic surgeon (32%) were key factors in deciding when they would like to discuss reconstruction. CONCLUSIONS: Most patients in our study indicated a preference for delay between initial consultation with a breast surgeon and initial consultation with a plastic surgeon. Incorporating patient preferences into the preoperative evaluation and planning process allows patients to optimize available support from loved ones and to begin coping with their diagnosis.

Mastectomy skin necrosis after microsurgical breast reconstruction.

BACKGROUND: Mastectomy skin necrosis represents a significant clinical morbidity after immediate breast reconstruction. In addition to aesthetic deformity, necrosis of the native mastectomy skin may require debridement, additional reconstruction, or prolonged wound care and potentially delay oncologic treatment. This study aims to evaluate patient and procedural characteristics to identify predictors of mastectomy skin necrosis after microsurgical breast reconstruction. METHODS: A retrospective review was performed of all immediate microsurgical breast reconstructions performed at a single academic center. Patient records were queried for age, diabetes, active smoking, previous breast surgery, preoperative radiation, preoperative chemotherapy, body mass index, mastectomy type, mastectomy weight, flap type, autologous flap type, and postoperative mastectomy skin flap necrosis. RESULTS: There were 746 immediate autologous microsurgical flaps performed by three plastic surgeons at our institution during the study period. The incidence of mastectomy skin flap necrosis was 13.4%. Univariate analysis revealed a significantly higher incidence of mastectomy skin necrosis in patients with higher mastectomy weight (P < 0.001), higher autologous flap weight (P < 0.001), higher body mass index (0.002), and diabetes (P = 0.021). No significant association was found for age, smoking, prior breast surgery, preoperative chemotherapy or radiation, or mastectomy type. Multivariate analysis demonstrated statistically significant associations between mastectomy skin necrosis and both increasing mastectomy weight (odds ratio 1.348 per quartile increase, P = 0.009) and diabetes (odds ratio 2.356, P = 0.011). CONCLUSIONS: Increasing mastectomy weight and coexisting diabetes are significantly associated with postoperative mastectomy skin necrosis after microsurgical reconstruction. These characteristics should be considered during patient counseling, procedure selection, operative planning, and intraoperative tissue viability assessment.

Tumescent mastectomy technique in autologous breast reconstruction.

BACKGROUND: Use of the tumescent mastectomy technique has been reported to facilitate development of a hydrodissection plane, reduce blood loss, and provide adjunct analgesia. Previous studies suggest that tumescent dissection may contribute to adverse outcomes after immediate implant reconstruction; however, its effect on autologous microsurgical reconstruction has not been established. METHODS: A retrospective review was conducted of all immediate microsurgical breast reconstruction procedures at a single academic center between January 2004 and December 2013. Records were queried for age, body mass index, mastectomy weight, diabetes, hypertension, smoking, preoperative radiation, reconstruction flap type, and autologous flap weight. Outcomes of interest were mastectomy skin necrosis, complete and partial flap loss, return to the operating room, breast hematoma, seroma, and infection. RESULTS: There were 730 immediate autologous breast reconstructions performed during the study period; 46% with the tumescent dissection technique. Groups were similar with respect to baseline patient and procedural characteristics. Univariate analysis revealed no significant difference in the incidence of mastectomy skin necrosis, complete or partial flap loss, return to the operating room, operative time, estimated blood loss, recurrence, breast hematoma, seroma, or infection in patients undergoing tumescent mastectomy. Multivariate analysis also demonstrated no significant association between the use of tumescent technique and postoperative breast mastectomy skin necrosis (P = 0.980), hematoma (P = 0.759), or seroma (P = 0.340). CONCLUSIONS: Use of the tumescent dissection technique during mastectomy is not significantly associated with adverse outcomes after microsurgical breast reconstruction. Despite concern for its impact on implant reconstruction, our findings suggest that this method can be used safely preceding autologous procedures.

Evaluation of the content and accessibility of microsurgery fellowship program websites.

Microsurgery fellowship applicants utilize Internet-based resources such as the San Francisco Match (SF Match) to manage their applications. In deciding where to apply, applicants rely on advice from mentors and online resources including microsurgery fellowship websites (MFWs). The purpose of this study was to evaluate the content and accessibility of MFWs. While microsurgery is practiced by many surgical specialties, this study focused on MFWs for programs available in the 2014 Microsurgery Fellowship Match. Program lists from the American Society for Reconstructive Microsurgery (ASRM) and the San Francisco Match (SF Match) were analyzed for the accessibility of MFW links. MFWs were evaluated for education and recruitment content, and MFW comprehensiveness was compared on the basis of program characteristics using chi square tests. Of the 25 fellowships available, only 18 had websites (72%). SF Match and ASRM listed similar programs (96% overlap) and provided website links (89%, 76%), but only a minority connected directly to the MFW (38%, 23%). A minority of programs were responsive via email inquiry (36%). MFWs maintained minimal education and recruitment content. MFW comprehensiveness was not associated with program characteristics. MFWs are often not readily accessible and contain limited information for fellowship applicants. Given the relative low-cost of website development, MFWs may be improved to facilitate fellow recruitment.

Near-infrared imaging for the assessment of anastomotic patency, thrombosis, and reperfusion in microsurgery: a pilot study in a porcine model.

BACKGROUND: Advances in microsurgical techniques have increased the use of free tissue transfer. Methods of intraoperative flap perfusion assessment, however, still rely primarily on subjective evaluation of traditional clinical parameters. Anastomotic thrombosis, if not expeditiously identified and revised, can result in flap loss with significant associated morbidity. This study aims to evaluate the use of near-infrared (NIR) fluorescence imaging in the assessment of microsurgical anastomotic patency, thrombosis, and vascular revision. MATERIALS AND METHODS: A model of pedicle thrombosis was created using bilateral abdominal flaps isolated on deep superior epigastric vascular pedicles in four Yorkshire pigs. Following flap elevation, microvascular arterial and venous anastomoses were performed unilaterally, preserving an intact contralateral control flap. Thrombosis was induced at the arterial anastomosis site using ferric chloride, and both flaps imaged using NIR fluorescence angiography. The thrombosed vascular segments were subsequently excised and new anastomoses performed to restore flow. Follow-up imaging of both flaps was then obtained to confirm patency using fluorescence imaging technology. RESULTS: Pedicled abdominal flaps were created and successful anastomotic thrombosis was induced unilaterally in each pig. Fluorescence imaging technology identified large decreases in tissue perfusion of the thrombosed flap within 2 minutes. After successful revision anastomosis, NIR imaging demonstrated dramatic increase in flow to the reconstructed flap, but intensity did not return to pre-thrombosis levels. CONCLUSIONS: Early identification of anastomotic thrombosis is important in successful free tissue transfer. Real-time, intraoperative evaluation of flap perfusion, anastomotic thrombosis, and successful revision can be performed using NIR fluorescence imaging.

Readability Assessment of Online Patient Abdominoplasty Resources.

BACKGROUND: Limited functional health literacy is recognized as an important contributor to health disparities in the United States. As internet access becomes more universal, there is increasing concern about whether patients with poor or marginal literacy can access understandable healthcare information. As such, the National Institutes of Health and American Medical Association recommend that patient information be written at a sixth grade level. This study identifies the most popular online resources for patient information about abdominoplasty and evaluates their readability in the context of average American literacy. METHODS: The two largest internet search engines were queried for "tummy tuck surgery" to simulate a patient search in lay terms. The ten most popular sites common to both search engines were identified, and all relevant articles from the main sites were downloaded. Sponsored results were excluded. Readability analysis of the articles was performed using ten established tests. RESULTS: Online information about abdominoplasty from the ten most popular publically available websites had an overall average readability of 12th grade. Mean reading grade level scores among tests were: Coleman-Liau 11.9, Flesch-Kincaid 11.4, FORCAST 11.1, Fry 13, Gunning Fog 13.5, New Dale-Chall 11.8, New Fog Count 9.9, Raygor Estimate 12, and SMOG 13.4; Flesch Reading Ease index score was 46. CONCLUSIONS: Online patient resources about abdominoplasty are uniformly above the recommended target readability level and are likely too difficult for many patients to understand. A range of readability identified among websites could allow surgeons to guide patients to more appropriate resources for their literacy skills.

Properties of meshes used in hernia repair: a comprehensive review of synthetic and biologic meshes.

BACKGROUND: Data on the mechanical properties of the adult human abdominal wall have been difficult to obtain rendering manufacture of the ideal mesh for ventral hernia repair a challenge. An ideal mesh would need to exhibit greater biomechanical strength and elasticity than that of the abdominal wall. The aim of this study is to quantitatively compare the biomechanical properties of the most commonly used synthetic and biologic meshes in ventral hernia repair and presents a comprehensive literature review. METHODS: A narrative review of the literature was performed using the PubMed database spanning articles from 1982 to 2012 including a review of company Web sites to identify all available information relating to the biomechanical properties of various synthetic and biologic meshes used in ventral hernia repair. RESULTS: There exist differences in the mechanical properties and the chemical nature of different meshes. In general, most synthetic materials have greater stiffness and elasticity than what is required for abdominal wall reconstruction; however, each exhibits unique properties that may be beneficial for clinical use. On the contrary, biologic meshes are more elastic but less stiff and with a lower tensile strength than their synthetic counterparts. CONCLUSIONS: The current standard of practice for the treatment of ventral hernias is the use of permanent synthetic mesh material. Recently, biologic meshes have become more frequently used. Most meshes exhibit biomechanical properties over the known abdominal wall thresholds. Augmenting strength requires increasing amounts of material contributing to more stiffness and foreign body reaction, which is not necessarily an advantage.

Online patient resources for hernia repair: analysis of readability.

BACKGROUND: The limited functional health literacy of a significant portion of the adult US population negatively affects their access to appropriate online health information about hernia repair surgery. The National Institutes of Health and American Medical Association recommend that patient-directed content should be written at a sixth-grade reading level. This study aims to evaluate readability of the most frequently used Internet resources for patient information about hernia repair relative to average American literacy. METHODS: A web search for "hernia repair surgery" was performed, and the top 12 Web sites were identified. Relevant articles (n=102) with patient-directed content immediately available from the main sites were downloaded. The 12 most popular consumer magazines in circulation were also identified, and using the same method, the first 10 articles were downloaded from each magazine's Web site for comparison. Readability was assessed using 10 established analyses. A t-test was used to compare the average grade level of hernia repair and magazine articles for each readability test. RESULTS: Web-based information about hernia repair had an overall average reading grade level of 13.6. All 102 articles were above the recommended sixth-grade reading level; these were significantly more difficult to read than the comparison group of articles from popular magazines. CONCLUSIONS: Online patient-directed information about hernia repair uniformly exceeds the recommended reading level and may be too difficult to be understood by a large portion of the US population.
