Comparative Analysis of Ventral Hernia Repair and Transverse Abdominis Release With and Without Panniculectomy: A 4-Year Match-Pair Analysis.

INTRODUCTION: Amid rising obesity, concurrent ventral hernia repair and panniculectomy procedures are increasing. Long-term outcomes of transverse abdominis release (TAR) combined with panniculectomy remain understudied. This study compares clinical outcomes and quality of life (QoL) after TAR, with or without panniculectomy. METHODS: A single-center retrospective review from 2016 to 2022 evaluated patients undergoing TAR with and without panniculectomy. Propensity-scored matching was based on age, body mass index, ASA, and ventral hernia working group. Patients with parastomal hernias were excluded. Patient/operative characteristics, postoperative outcomes, and QoL were analyzed. RESULTS: Fifty subjects were identified (25 per group) with a median follow-up of 48.8 months (interquartile range, 43-69.7 months). The median age and body mass index were 57 years (47-64 years) and 31.8 kg/m2 (28-36 kg/m2), respectively. The average hernia defect size was 354.5 cm2 ± 188.5 cm2. There were no significant differences in hernia recurrence, emergency visits, readmissions, or reoperations between groups. However, ventral hernia repair with TAR and panniculectomy demonstrated a significant increase in delayed healing (44% vs 4%, P < 0.05) and seromas (24% vs 4%, P < 0.05). Postoperative QoL improved significantly in both groups (P < 0.005) across multiple domains, which continued throughout the 4-year follow-up period. There were no significant differences in QoL among ventral hernia working group, wound class, surgical site occurrences, or surgical site occurrences requiring intervention (P > 0.05). Patients with concurrent panniculectomy demonstrated a significantly greater percentage change in overall scores and appearance scores. CONCLUSIONS: Ventral hernia repair with TAR and panniculectomy can be performed safely with low recurrence and complication rates at long-term follow-up. Despite increased short-term postoperative complications, patients have a significantly greater improvement in disease specific QoL.

Extracorporeal Membrane Oxygenation-Associated Compartment Syndrome: Review of a National Database.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO)-associated compartment syndrome (CS) is a rare complication seen in critically ill patients. The epidemiology and management of ECMO-associated CS in the upper extremity (UE) and lower extremity (LE) are poorly defined in the literature. We sought to determine the epidemiology and characterize treatment and outcomes of UE-CS compared to LE-CS in the setting of ECMO therapy. METHODS: Adult patients undergoing ECMO therapy were identified in the Nationwide Readmission Database (2015-2019) and followed up for 6 months. Patients were stratified based on UE-CS versus LE-CS. Primary outcomes were fasciotomy and amputation. All-cause mortality and length of stay were also collected. Risk-adjusted modeling was performed to determine patient- and hospital-level factors associated with differences in the management UE-CS versus LE-CS while controlling for confounders. RESULTS: A total of 24,047 cases of ECMO during hospitalization were identified of which 598 were complicated by CS. Of this population, 507 cases were in the LE (84.8%), while 91 (15.5%) were in the UE. After multivariate analysis, UE-CS patients were less likely to undergo fasciotomy (50.5 vs. 70.9; P = 0.013) and were less likely to undergo amputation of the extremity (3.3 vs. 23.7; P = 0.001) although there was no difference in mortality (58.4 vs. 65.4; P = 0.330). CONCLUSIONS: ECMO patients with CS experience high mortality and morbidity. UE-CS has lower rates of fasciotomy and amputations, compared to LE-CS, with similar mortality. Further studies are needed to elucidate the reasons for these differences.

Breast Explantation With Simultaneous Mastopexy and Volume Restoration: An Analysis of Clinical Outcomes and Prospective Quality of Life.

BACKGROUND: An increasing number of patients are undergoing explantation to alleviate symptoms attributed to the presence of a prothesis or dissatisfaction with the appearance of their breasts. OBJECTIVES: The authors aim to evaluate the clinical effectiveness and quality of life (QoL) of simultaneous explantation, capsulectomy, and mastopexy for patients requesting implant removal. METHODS: Two hundred sixty-two simultaneous explantation, capsulectomy, and mastopexy (ECM) procedures were performed in 131 patients from 2009 to 2019. Prospective QoL assessment was administered for all patients. Inclusion criteria included a minimum postoperative follow-up of 6 months and completion of a practice-generated patient reported outcomes (PRO) questionnaire. Wilcoxon signed-rank test was performed to compare changes in QoL scores. RESULTS: Mean follow-up and BMI were 23 months (6 months to 8 years) and 24.8 kg/m2 (18-34 kg/m2), respectively. Mean age was 48.3 years (26-75 years). Autologous fat grafting was performed simultaneously in patients 47.3% (n = 62). The complication rate was 3.8% (n = 10 breasts) in 9 patients (6.9%). The overall reoperation rate was 7.3% of procedures (n = 19 breasts) and 9.2% of patients (n = 12), including secondary autologous fat grafting (11.3%, n = 7). PRO results demonstrated a significant improvement in all QoL domains, including physical well-being (P < .005), psychological well-being (P < .005), sexual well-being (P < .005), breast shape (P < .005), and breast appearance (P < .005). With respect to breast implant illness symptoms, 59 patients (88.1%) noted reduced pain, myalgias/arthralgias, and fatigue after ECM. CONCLUSIONS: This study presents an effective paradigm to manage implant removal through simultaneous explantation, capsulectomy, and mastopexy with acceptable clinical outcomes and a significant improvement in QoL and breast aesthetics.

Integration and Implementation of Patient-Reported Outcomes: A Prospective, Observational Clinical Quality Improvement Study.

BACKGROUND: Implementation of patient-reported outcomes (PROs) represents a critical barrier to their widespread use and poses challenges to workflow and patient satisfaction. The authors sought to implement PRO surveys into surgical practice and identify principles for successful and broader implementation. METHODS: Outpatient surgical encounters from 2016 through 2019 related to hernia, breast surgery, or postbariatric body contouring were assessed with the Abdominal Hernia-Q, BREAST-Q, or BODY-Q surveys, respectively. Outcomes were implementation rates per quarter and time to optimal implementation (≥80%). Successful implementation principles were identified during the first implemented PRO instrument and applied to subsequent ones. Logistic regression models were used to estimate increase in rate of implementation per quarter by instrument controlling for clinic volume. Risk-adjusted generalized linear models determined predicted mean differences in total clinic time and patient satisfaction. RESULTS: A total of 1206 encounters were identified. The overall survey implementation rate increased from 15% in the first quarter to 90% in the last quarter ( P < 0.01). Abdominal Hernia-Q optimal implementation was reached by 15 months. Principles for successful implementation of PROs were workflow optimization, appropriate patient selection, staff engagement, and electronic survey integration. Consistent application of these principles optimized time to optimal implementation for BREAST-Q [9 months; 18.1% increase in implementation per quarter (95% CI, 1.5 to 37.5); P < 0.01] and BODY-Q [3 months; 56.3% increase in implementation per quarter (95% CI, 26.8 to 92.6); P = 0.03]. Neither patient clinic time ( P = 0.16) nor patient satisfaction differed during the implementation of PROs process ( P = 0.98). CONCLUSIONS: Prospective implementation of PROs can be achieved in surgical practice without an adverse effect on patient satisfaction or workflow. The proposed principles of implementation may be used to optimize efficiency for implementation of PROs.

Prospective Assessment of the Abdominal Hernia-Q (AHQ)-Patient Burden, Reliability, and Longitudinal Assessment of Quality of Life in Hernia Repair.

OBJECTIVE: This study assesses the user burden, reliability, and longitudinal validity of the AHQ, a novel VH patient-reported outcomes measure (PROM). BACKGROUND: We developed and psychometrically validated the AHQ as the first VH-specific, stakeholder-informed PROM. Yet, there remains a need to assess the AHQ's clinical applicability and further validate its psychometric properties. METHODS: To assess patient burden, pre- and postoperative patients were timed while completing the corresponding AHQ form. To measure test-retest reliability, a subset of patients completed the AHQ within a week of initial completion, and consecutive responses were correlated. Lastly, patients undergoing VH repair were prospectively administered the pre- and postoperative AHQ forms, the Hernia-Related Quality of Life Survey and the Short Form-12 both preoperatively and at postoperative intervals, up to over a year after surgery. Quality-of-Life scores were correlated from the 3 PROMs and effect sizes were compared using analysis of normal variance. RESULTS: Median response times for the pre- and postoperative AHQ were 1.1 and 2.7 minutes, respectively. The AHQ demonstrates high test-retest reliability coefficients for pre- and postoperative instruments ( r = 0.91, 0.89). The AHQ appropriately and proportionally measures expected changes following surgery and significantly correlates with all times points of theHernia-Related Quality of Life Survey and Short Form-12 MS and 4/5 (80%) SF12-PS. CONCLUSION: The AHQ is a patient-informed, psychometrically-validated, clinical instrument for measuring, quantifying, and tracking PROMs in VH patients. The AHQ exhibits low response burden, excellent reliability, and effectively measures hernia-specific changes in quality-of-Life following ventral hernia repair.

Redesign of US Medical Schools: A Shift from Health Service to Population Health Management.

The integration of medical schools and clinical partners is effectively established through the formation of academic medical centers (AMCs). The tripartite mission of AMCs emphasizes the importance of providing critical clinical services, medical innovation through research, and the education of future health care leaders. Although AMCs represent only 5% of all hospitals, they contribute substantially to serving disadvantaged populations of patients, including an estimated 37% of all charity care and 26% of all Medicaid hospitalizations. Currently, most AMCs use a business model centered upon revenue generated from hospital services and/or practice plans. In the last decade, mounting financial demands have placed significant pressure on AMC finances because of the rising costs associated with complex clinical care and operating diverse graduate medical education programs. A shift toward population health-centric health care management strategies will profoundly influence the predominant forms of health care delivery in the United States in the foreseeable future. Health systems are increasingly pursuing new strategies to manage financial risk, such as forming Accountable Care Organizations and provider-sponsored plans to provide value-based care. Refocusing research and operational capacity toward population health management fosters collaboration and enables reintegration with hospital and clinical partners across care networks, and can potentially create new revenue streams for AMCs. Despite the benefits of population health integration, current literature lacks a blueprint to guide AMCs in the transformation toward sustainable population health management models. The purpose of this paper is to propose a modern conceptual framework that can be operationalized by AMCs in order to achieve a sustainable future.

Sticking to What Matters: A Matched Comparative Study of Fibrin Glue and Mechanical Fixation for Split-Thickness Skin Grafts in the Lower Extremity.

Background: Split-thickness skin grafts (STSGs) remain a valuable tool in the reconstructive surgeons' armamentarium. Staple or suture mechanical fixation (MF) serves as the gold standard of care, though fibrin glue (FG) has gained popularity as a fixation modality. We compare STSG outcomes following application of FG versus MF through a study of lower extremity wounds. Methods: A retrospective review (2016-2019) of patients who underwent a STSG was performed. Two cohorts consisting of patients undergoing a STSG with FG or MF (suture or staple) were matched according to wound size, wound location, and body mass index. Results: A total of 67 patients with 79 wounds were included (FG: n = 30, wounds = 39; MF: n = 37; wounds = 40). There was no significant difference between groups regarding time to 100% graft take (FG: 39 days, MF: 35.1 days; P < .384) or 180-day graft complications (FG: 10.3%, MF: 15%; P < .737). Adjusted operative time for FG (51.8 min) was lower than for MF cases (67.5 min) at a level that approached significance (P < .094). FG patients were significantly less likely to require a postoperative wound vacuum-assisted closure (VAC) (FG: 16.7%; MF: 76.7%; P < .001) and required a significantly lower number of 30-day postoperative visits (FG: 1.5 ± .78 visits; MF: 2.5 ± .03 visits; P < .001). The MF group had higher mean aggregate charges ($211,090) compared with the FG group (mean: $149,907), although these were not statistically significant (P > .05). Conclusion: The use of FG for STSG shows comparable clinical outcomes to MF, with a significantly decreased need for postoperative wound VAC, the number of 30-day postoperative visits, and a lower wound-adjusted operative time.

Quality of Life and Complications in the Morbidly Obese Patient following Post-Bariatric Body Contouring.

BACKGROUND: With a growing obesity epidemic, an increasing number of patients are seeking body contouring procedures (BCP). The aim of this study was to assess the association of morbid obesity (BMI > 40 kg/m2) with both clinical and health-related quality of life (H-RQOL) outcomes following BCP. METHODS: Patients evaluated for post-bariatric BCP at a large academic hospital by one surgeon were retrospectively identified. Patients were surveyed using the BODY-Q© during initial and postoperative visits. Demographic, clinical, operative characteristics, and surgical outcomes data were extracted. BODY-Q domain scores were compared between morbidly obese (MO) and non-morbidly obese (NMO). The absolute change in HR-QOL scores for MO and NMO was also compared. RESULTS: Overall, 59 patients were included (MO 72.9% vs. NMO 27.1%). The median age was 50 years old (Interquartile range [IQR] ± 17); the majority were non-Hispanic (89.8%), non-diabetic (81.4%), non-smokers (67.8%). Assessment of surgical site occurrences, reoperations, and the complication composite outcome revealed no statistical differences between groups (p >0.05). MO patients showed lower net improvement in three HR-QOL domains: satisfaction with body (median 30 [IQR ± 53] vs. 65 [IQR ± 54]; p = 0.036), body image (median 39 [IQR ± 55] vs. 52 [IQR ± 44]; p = 0.025), and social function (median 12 [IQR ± 18] vs. 19 [IQR ± 35]; p = 0.015). CONCLUSION: Post-bariatric BCP can be safely performed in the MO patient without increased risk of complication. However, the benefit of truncal BCP is less in MO as it pertains to specific QOL domains: satisfaction with body, body image, and social function.

Biomechanical Parameters of Mesh Reinforcement and Analysis of a Novel Device for Incisional Hernia Prevention.

BACKGROUND: Prophylactic mesh augmentation (PMA) is an effective technique utilized to reduce the risk of incisional hernia. This study analyzes the biomechanical characteristics of a mesh-reinforced closure and evaluates a novel prophylactic mesh implantation device (SafeClose Roller System; SRS). MATERIALS AND METHODS: A total of eight senior-level general surgery trainees (≥4 years of training) from the University of Pennsylvania Health System participated in the study. Biomechanical strength, mesh stiffness, mesh uniformity, and time efficiency for fixation were compared among hand-sewn mesh fixation, SRS mesh fixation and a no-mesh fixation control. Porcine abdominal wall specimens served as simulated laparotomy models. RESULTS: Biomechanical load strength was significantly higher for mesh reinforced repairs (P = 0.009). The SRS resulted in a stronger biomechanical force than hand-sewn mesh (21.2 N stronger, P = 0.317), with more uniform mesh placement (P < 0.01), faster time of fixation (P < 0.001) and with less discrete hand-movements (P < 0.001). CONCLUSIONS: Mesh reinforcement for incisional reinforcement has a significant impact on the strength of the closure. The utilization of a mesh-application system has the potential to amplify the advantages of mesh reinforcement by providing efficiency and consistency to fixation methods, with similar biomechanical strength to hand-sewn mesh. Additional in vivo analysis and randomized controlled trials are needed to further assess clinical efficacy.

Characteristics of the Superficial Circumflex Iliac Artery Perforator Flap in a Western Population and a Practice Approach for Free Flap Reconstruction.

BACKGROUND: There has been increasing interest in the superficial circumflex iliac artery perforator (SCIP) flap as a source of thin, pliable soft tissue combined with a favorable donor site. Despite several clinical series from Asia, barriers to adoption include reluctance to perform submillimeter "supermicrosurgery" and the effect of body habitus on flap feasibility. The purpose of this study is to distinguish vascular anatomic characteristics of the SCIP flap in a North American population. METHODS: Computed tomography angiography was examined in 84 flaps in healthy prospective renal donor patients from a radiographic database. Descriptive statistics as well as linear regression comparing variables to body mass index (BMI) were performed. RESULTS: Mean BMI was 27.1 ± 3.5 kg/m2, while the mean patient age was 47.8 ± 11.4 years. The superficial circumflex iliac artery (SCIA) originated from the common femoral artery in 92% cases, with remainder originating from the profunda femoris. The mean vessel diameter was 1.85 mm at source vessel origin. Distance from skin to source vessel averaged 30.7 mm. Suprascarpal subcutaneous thickness averaged 16.5 mm. The mean distance from Scarpa's fascia to vessel origin was 14.1 mm. Direct three-dimensional distance from vessel origin to pubic tubercle was 50.2 mm. A medial and lateral perforator split off of the SCIA was observed in 38 cases (45%). Significant differences were shown when comparing BMI to skin to source vessel distance (p < 0.001), suprascarpal subcutaneous fat thickness (p < 0.001), and fascial distance to vessel origin (p < 0.001). BMI did not significantly affect vessel diameter. CONCLUSION: Despite a significantly higher BMI than many previously published cohorts, the SCIP remains an excellent source of thin and pliable tissue. When dissected closer to the source vessel, a vessel caliber of nearly 2 mm can be achieved, which may obviate the need for "supermicrosurgery" in this population.

Indications and Limitations of Bilayer Wound Matrix-Based Lower Extremity Reconstruction: A Multidisciplinary Case-Control Study of 191 Wounds.

BACKGROUND: Little is known about the efficacy of newer skin substitute scaffolds to reconstruct complex lower extremity wounds. The investigators present a multihospital experience of reconstructive surgeons utilizing collagen-GAG bilayer wound matrix in lower extremity soft-tissue reconstruction with the goals to (1) characterize a suitable patient population, (2) categorize failures to optimize patient selection, and (3) determine wound factors affecting success. METHODS: Subjects underwent collagen-GAG-based lower extremity wound reconstruction from May of 2010 to June of 2017. The primary outcome variable was 180-day graft success, defined as eventual split-thickness skin grafting after bilayer wound matrix application; failure was defined as inadequate wound bed for split-thickness skin grafting, requirement for vascularized tissue transfer, or eventual amputation. Eligible subjects had at least one lower extremity wound and were at least 18 years old. Exclusion criteria included third-degree burn wounds or failure to follow up for at least 60 days postoperatively. Predictor variables included demographics, medical comorbidities, perioperative characteristics, postoperative complications, and cost-related data for each hospitalization. RESULTS: There were 147 subjects with 191 wounds. Mean patient age was 60.1 years (range, 21.0 to 95.6 years), and mean body mass index was 30.5 kg/m (range, 14.4 to 64.7 kg/m). Average wound size was 73.1 ± 137.7 cm, with 49.0 percent of subjects receiving adjunct postoperative negative-pressure wound therapy. Seventy percent of wounds were successfully healed at 180 days. Most were localized between the knee and ankle (50.8 percent) or foot (46.1 percent). Tendon exposure (p < 0.05), bone exposure (p < 0.01), and bone excision (p < 0.04) were associated with reconstructive failure. CONCLUSIONS: The authors present the largest reported multihospital, multidisciplinary experience with collagen-GAG wound matrix for lower extremity reconstruction. Tendon and/or bone exposure and socioeconomic factors were associated with failure. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Outcomes of Poly-4-hydroxybutyrate Mesh in Ventral Hernia Repair: A Systematic Review and Pooled Analysis.

Within the past decade, poly-4-hydroxybutyrate (P4HB) biosynthetic mesh has been introduced as a potential alternative to traditional biologic and synthetic mesh in ventral hernia repair (VHR). The aim of this study was to systematically assess clinical outcomes with the P4HB in VHR. METHODS: A literature search identified all articles published in 2000 involving the use of P4HB in VHR. Descriptive statistics were used to synthesize collective data points, including postoperative outcomes. A pooled analysis of postoperative outcomes was performed using chi-square test and Fisher exact test. RESULTS: Across 7 studies, the P4HB was used in 453 patients. The mean rate of surgical site infection (SSI) was 6.8% (31/453), reoperation 10.7% (30/281), and recurrence 9.1% (41/453). At an average follow-up of 26.8 months, the incidence of recurrence was 10.4% (28/270). Onlay was significantly associated with increased recurrence (14.2% versus 4.4%, P = 0.001). Among sublay placements, there was no difference in recurrence in clean (Center for Disease Control [CDC] 1) or contaminated (CDC >1) wounds (2.7% versus 6.1%, P = 0.585), but contaminated wounds were associated with increased SSI (2.7% versus 15.2%, P = 0.028). Ventral Hernia Working Group grade 2 and 3 did not have different incidences of recurrence (8.0% versus 5.1%, P = 0.526) nor SSI (5.1% versus 14.6%, P = 0.265). CONCLUSIONS: Overall, clinical outcomes of the P4HB mesh in VHR are acceptable. The P4HB mesh serves as a reliable alternative to traditional synthetic and biologic mesh across a range of defect characteristics and patient health conditions. Further research is needed to better understand the conditions in which it may provide a clinical benefit over traditional mesh types.

Can We Predict Incisional Hernia?: Development of a Surgery-specific Decision-Support Interface.

OBJECTIVE: The aim of this study was to identify procedure-specific risk factors independently associated with incisional hernia (IH) and demonstrate the feasibility of preoperative risk stratification through the use of an IH risk calculator app and decision-support interface. SUMMARY BACKGROUND DATA: IH occurs after 10% to 15% of all abdominal surgeries (AS) and remains among the most challenging, seemingly unavoidable complications. However, there is a paucity of readily available, actionable tools capable of predicting IH occurrence at the point-of-care. METHODS: Patients (n = 29,739) undergoing AS from 2005 to 2016 were retrospectively identified within inpatient and ambulatory databases at our institution. Surgically treated IH, complications, and costs were assessed. Predictive models were generated using regression analysis and corroborated using a validation group. RESULTS: The incidence of operative IH was 3.8% (N = 1127) at an average follow-up of 57.9 months. All variables were weighted according to ß-coefficients generating 8 surgery-specific predictive models for IH occurrence, all of which demonstrated excellent risk discrimination (C-statistic = 0.76-0.89). IH occurred most frequently after colorectal (7.7%) and vascular (5.2%) surgery. The most common occurring risk factors that increased the likelihood of developing IH were history of AS (87.5%) and smoking history (75%). An integrated, surgeon-facing, point-of-care risk prediction instrument was created in an app for preoperative estimation of hernia after AS. CONCLUSIONS: Operative IH occurred in 3.8% of patients after nearly 5 years of follow-up in a predictable manner. Using a bioinformatics approach, risk models were transformed into 8 unique surgery-specific models. A risk calculator app was developed which stakeholders can access to identify high-risk IH patients at the point-of-care.

Retromuscular Mesh Repair Using Fibrin Glue: Early Outcomes and Cost-effectiveness of an Evolving Technique.

BACKGROUND: Retromuscular hernia repairs (RHRs) decrease hernia recurrence and surgical site infections but can cause significant pain. We aimed to determine if pain and postoperative outcomes differed when comparing suture fixation (SF) of mesh to fibrin glue fixation (FGF). METHODS: Patients undergoing RHR (n = 87) between December 1, 2015 and December 31, 2017 were retrospectively identified. Patients received SF of mesh (n = 59, 67.8%) before the senior author changing his technique to FGF (n = 28, 32.2%). These 2 cohorts were matched (age, body mass index, number of prior repairs, mesh type, defect size, and wound class). Outcomes were analyzed using a matched pairs design with multivariable linear regression. RESULTS: Two matched groups (21 FGF and 21 SF) were analyzed (45.2% female, average age 56 years, average body mass index 34.7 kg/m2, and average defect size 330 cm2). Statistical significance was observed for FGF compared with SF: length of stay (3.7 versus 7.1 days, P = 0.032), time with a drain (17.2 versus 27.5 days, P = 0.012), 30-day postoperative visits (2 versus 3, P = 0.003), pain scores (5.2 versus 3.1, P = 0.019) and activity within the first 24 hours (walking versus sitting, P = 0.002). Operative time decreased by 23.1 minutes (P = 0.352) and postoperative narcotic represcription (3 versus. 8 patients, p=0.147) also decreased. Average cost for patients receiving SF was $36,152 compared to $21,782 for FGF (P = 0.035). CONCLUSIONS: Sutureless RHR using FGF may result in decreased pain when compared with a matched cohort receiving SF, translating to enhanced recovery time, shortened hospital stay, and decreased costs.

To Glue or Not to Glue? Analysis of Fibrin Glue for Split-thickness Skin Graft Fixation.

BACKGROUND: Split-thickness skin grafting (STSG) is a commonly used tool in the plastic surgeon's reconstructive armamentarium. Fibrin glue (FG) consists of a combination of clotting factors and thrombin whose key properties include adherence and hemostasis. This preliminary study aimed to assess clinical outcomes and cost of FG for STSG fixation in a general wound reconstruction. METHODS: A retrospective review was conducted in all patients undergoing STSG placement by a single surgeon (JPF) from January 2016 to March 2018. Twenty patients were identified and matched by wound location and wound size. Patients were then divided into 2 groups based on the method of STSG fixation: FG (n = 10) or suture only (SO) (n = 10). RESULTS: In patients with FG fixation, we observed trends of decreased adjusted operative times (34.9 versus 49.4 minutes, P = 0.612), a similar length of stay (2.8 versus 3.5 days, P = 0.306), and liberation from the use of negative pressure wound therapy (0 versus 10 wounds, P < 0.0001). There were no observed differences between the 2 groups in terms of graft-related complications at 180 days (1 complication FG versus 0 complications SO). Time to 100% graft take was also not different (20.2 versus 29.4 days, P = 0.405). Additionally, total direct cost ($16,542 FG versus $24,266 SO; P = 0.545) and total charges ($120,336 FG versus $183,750 SO; P = 0.496) were not statistically different between the FG and SO groups. CONCLUSIONS: In this preliminary comparative assessment, FG for STSG fixation has shown no difference in clinical outcomes to SO fixation, trends of decreased operative time, and afforded complete liberation from negative pressure wound therapy dressings.

Ultrasonic debridement management of lower extremity wounds: retrospective analysis of clinical outcomes and cost.

OBJECTIVE: The aim of this study was to assess wound healing outcomes following direct, low-frequency, high-intensity, ultrasonic debridement as a surgical adjunct for non-healing lower extremity wounds. METHODS: A retrospective review was conducted for patients undergoing lower extremity wound treatment with direct, low-frequency (22.5 kHz), high-intensity (~60 W/cm2) ultrasonic debridement between January 2010 and January 2016. Clinical outcomes were assessed up to 180-days post-ultrasonic debridement. Descriptive statistics, cost and univariate analysis were performed. RESULTS: Overall, 82 wounds in 51 patients were included. Mean age was 57.0 years (range: 32-69), and average body mass index (BMI) was 30.8 kg/m². Patient comorbidities consisted of smoking (47%; n=24), hypertension (75%; n=38), diabetes (45%; n=23), and peripheral vascular disease (51%, n=26). Average wound age at initial presentation was 1013 days (range: 2-5475 days) with an average wound size of 9.0cm x 7.4cm. At 180-days post-debridement, 60% (n=49) of wounds had completely healed. Readmission (47%; n=24) and reoperation (45%; n=23) rates were characterised by the reason for readmission and reoperation respectively. Readmission for wound healing (70%, n=39) was primarily for further debridements (41%; n=16). Wound infection (30%; n=7) was the most common readmission for wound complications (30%; n=17). Reoperations primarily consisted of treatments for further wound healing 96% (n=51). Cost analysis showed a lower total treatment cost for patients with improved healing ($78,698), compared with non-improved wounds ($137,707). CONCLUSION: In a complex, heterogeneous cohort of chronic extremity wounds, the use of direct, low-frequency, high-intensity, ultrasonic debridement is a safe and reliable adjunctive therapy for the management of these wounds.

One-Stage Augmentation Mastopexy: A Retrospective Ten-Year Review of 2183 Consecutive Procedures.

BACKGROUND: Although numerous studies supporting breast augmentation with simultaneous mastopexy have been reported, concerns persist among surgeons regarding the safety of this procedure. OBJECTIVES: The authors sought to evaluate the safety and effectiveness of 1-stage augmentation mastopexy by analyzing long-term complication and reoperation rates. METHODS: The authors conducted a retrospective review of 1131 patients who underwent 2183 consecutive 1-stage augmentation mastopexy procedures from January 2006 to August 2016. Patient demographics, operative technique, and implant specifications were measured and analyzed with surgical outcomes. Long-term complication and reoperation rates were noted. RESULTS: Over a mean follow-up period of 43 months (range, 4-121 months), the overall complication rate was 15.3% (n = 173) with a reoperation rate of 14.7% (n = 166). Tissue-related complications included hypertrophic scarring in 2.5% (n = 28) and recurrent ptosis in 2.1% (n = 24). The most common implant-related complication was capsular contracture (Baker III or IV) in 2.8% (n = 32). The most common indications for reoperation were recurrent ptosis in 3.5% (n = 40 patients) and desire to change implant size in 3.2% (n = 36 patients). Circumareolar augmentation mastopexy technique was associated with a higher reoperation rate of 25.7% (P < 0.0005). Patients with a history of smoking had a higher incidence of complications (26.1%) and reoperations (22.5%; P < 0.0005). There were no cases of significant skin flap necrosis (>2 cm). CONCLUSIONS: One-stage augmentation mastopexy can be safely performed with a reoperation rate that is significantly lower than when the procedure is staged. The effectiveness of this procedure is defined by a low complication rate and a reduced number of operations for the patient.

When the Mesh Goes Away: An Analysis of Poly-4-Hydroxybutyrate Mesh for Complex Hernia Repair.

Mesh reinforcement is a cornerstone of modern ventral hernia repair (VHR); yet, complications with synthetic mesh and cost of biologic have created a need for alternative options. Biosynthetic mesh is a resorbable scaffold that theoretically leverages the benefits and minimizes deficiencies of existing mesh types. This study evaluates 2-year outcomes following poly-4-hydroxybutyrate (P4HB) mesh reinforcement for complex VHR. METHODS: A retrospective review of all consecutive VHR with P4HB (n = 70) was conducted from 2015 to 2018 by a single surgeon. Clinical outcomes, quality of life (QoL; and cost were assessed. RESULTS: Seventy patients were included with an average age and body mass index of 58.6 years and 33 kg/m2, respectively. High-risk comorbidities included hypertension (59%), and smoking history (50%). Cases were primarily modified Ventral Hernia Working Group class 2 (50%), or 3 (36%), with average defect size of 323 cm2 (25-972 cm2). P4HB was placed in the retromuscular (80%) or onlay (20%) plane. Mean follow-up was 24 months (12.2-41 months). Hernia recurrence rate was 5.7% (n = 4) and occurred an average of 285 days (209-368 days) post-repair. Of the 21 surgical site occurrences (SSO), 5 (7%) required surgical intervention. A significant improvement in overall QoL (P = 0.001) was noted following repair. Defect size and SSOPI were independently associated with increased direct cost. CONCLUSIONS: P4HB mesh for complex VHR is associated with favorable 2-year clinical outcomes, acceptable hernia recurrence rate, and a significant improvement in QoL. This study supports the use of biosynthetic mesh as an effective biomaterial for complex VHR.

Using Crowdsourcing as a Platform to Evaluate Lay Perception of Prophylactic Mesh Placement.

BACKGROUND: Prophylactic mesh placement (PMP) at the time of open abdominal surgery has gained momentum over the last decade. However, there remains an identifiable gap in the literature regarding patient-reported outcomes and qualitative metrics. In effort to gauge the population's understanding or familiarity with PMP, this study provides an educational framework and uses crowdsourcing as a novel means to assess perception among the general population. METHODS: A cross-sectional survey study was conducted among the general public to elicit perspectives on PMP. An online crowdsourcing platform was used to capture responses to a questionnaire. Pearson's correlation coefficients, paired t-test, chi-square test, and Fisher's exact tests were performed. RESULTS: Of 433 respondents, 338 (78.1%) were included. Individuals who had previously undergone surgery and those who had prior hernia repair were more likely to choose PMP than surgically naïve patients (P = 0.06). CONCLUSIONS: The majority of respondents support the use of PMP. This study contributes to the existing body of literature on PMP and serves as the first qualitative description to gauge the population's perception and understanding of this surgical technique. Within the evolving health care landscape, understanding quality-of-life measures have become increasingly important in defining successful surgical outcomes. Although the data-driven level-I evidence supports the clinical use of PMP, this study intends to establish a framework for future patient-reported outcome studies.

Role of Prophylactic Mesh Placement for Laparotomy and Stoma Creation.

Incisional and parastomal hernias are a cause of significant morbidity and have a substantial effect on quality of life and economic costs for patients and hospital systems. Although many aspects of abdominal hernias are understood, prevention is a feature that is still being realized. This article reviews the current literature and determines the utility of prophylactic mesh placement in prevention of incisional and parastomal hernias.
