Determining the Association Between Insurance Type and Myofascial Release in Large Ventral Hernias.

INTRODUCTION: Abdominal wall reconstruction (AWR) utilizes advanced myofascial releases to perform complex ventral hernia repair (VHR). The relationship between the performance of AWR and disparities in insurance type is unknown. METHODS: The Abdominal Core Health Quality Collaborative was queried for adults who had undergone an elective VHR between 2013 and 2020 with a hernia size ≥10 cm. Patients with missing insurance data were excluded. Comparison groups were divided by insurance type: favorable (private, Medicare, Veteran's Administration, Tricare) or unfavorable (Medicaid and self-pay). Propensity score matching compared the cumulative incidence of AWR between the favorable and unfavorable insurance comparison groups. RESULTS: In total, 26,447 subjects met inclusion criteria. The majority (89%, n = 23,617) had favorable insurance, while (11%, n = 2830) had unfavorable insurance. After propensity score matching, 2821 patients with unfavorable insurance were matched to 7875 patients with favorable insurance. The rate of AWR with external oblique release or transversus abdominis release was significantly higher (23%, n = 655) among the unfavorable insurance group compared to those with favorable insurance (21%, n = 1651; P = 0.013). CONCLUSIONS: This study provides evidence that patients with unfavorable insurance may undergo AWR with external oblique or transversus abdominis release at a greater rate than similar patients with favorable insurance. Understanding the mechanisms contributing to this difference and evaluating the financial implications of these trends represent important directions for future research in elective VHR.

Are Nerves Left In Situ Associated With Less Chronic Pain Than Manipulation During Inguinal Hernia Repair?

INTRODUCTION: Nerve damage has been implicated in chronic groin pain, particularly iliohypogastric, ilioinguinal, and genital branches of genitofemoral nerves. We investigated whether three nerve identification (3N) and preservation is associated with decreased pain 6 mo after hernia repair compared to two common strategies of nerve management: ilioinguinal nerve identification (1N) and two nerve identification (2N). METHODS: We identified adult inguinal hernia patients within the Abdominal Core Health Quality Collaborative national database. Six-month postoperative pain was defined using the EuraHS Quality of Life tool. A proportional odds model was used to estimate odds ratios (ORs) and expected mean differences in 6-month pain for nerve management while adjusting for confounders identified a priori. RESULTS: Four thousand four hundred fifty one participants were analyzed; 358 (3N), 1731 (1N), and 2362 (2N) consisting mostly of White males (84%) over the age of 60 y old. Academic centers identified all three nerves more often than ilioinguinal or two nerve identification methods. Median 6-month postoperative pain scores were 0 [interquartile range 0-2] for all nerve management groups (P = 0.51 3N versus 1N and 3N versus 2N). There was no evidence of a difference in the odds of higher 6-month pain score in nerve management methods after adjustment (3N versus 1N OR: 0.95; 95% confidence interval 0.36-1.95, 3N versus 2N OR: 1.00; 95% confidence interval 0.50-1.85). CONCLUSIONS: Although guidelines emphasize three nerve preservation, the management strategies evaluated were not associated with statistically significant differences in pain 6 mo after operation. These findings suggest that nerve manipulation may not contribute as a significant role in chronic groin pain after open inguinal hernia repair.

Community distress as a predictor of early hernia recurrence for older adults undergoing ventral hernia repair (VHR).

BACKGROUND: Social cohesion and neighborhood support have been linked to improved health in a variety of fields, but is not well-studied among the elderly population. This is particularly evident in surgical populations. Therefore, this study sought to assess the potential role of community distress in predicting early hernia recurrence among older adults. METHODS: The Abdominal Core Health Quality Collaborative (ACHQC) was used to identify patients aged 65 or older undergoing elective ventral hernia repair with zip code data available. Patients were linked to the Distressed Communities Index (DCI), which is a national database that assigns a score of 0-100 to each zip code based on 7 measures of neighborhood prosperity. Quintiles were used to compare groups: prosperous (0-20), comfortable (21-40), mid-tier (41-60), at-risk (61-80), and distressed (81-100). Distressed (0-20), at-risk (21-40), mid-tier (41-60), comfortable (61-80), and prosperous (81-100). Time to recurrence for neighborhood distress quintiles was examined using a Cox proportional hazards model. RESULTS: In total, 9819 patients were included in the study, including 3056 (31.1%) prosperous, 2307 (23.5%) comfortable, 1795 (18.2%) mid-tier, 1390 (14.2%) at-risk, and 1271 (12.9%) distressed. Distressed communities had lower mean age and greater proportion of racial minorities (p < 0.001). Open repairs were significantly more common among the distressed group (66.7%), as were all comorbidities (p < 0.001). Recurrence-free survival was shorter for distressed communities compared to prosperous after adjusting for baseline characteristics (HR 1.3, 95% CI 1.07-1.67, p = 0.01). Mean time to recurrence was lowest for patients living in distressed communities, indicating the worst recurrence rates, while mean time to recurrence was greatest for those in prosperous zip codes (p < 0.001). CONCLUSION: Older VHR patients presenting from distressed zip codes, as identified by the Distressed Communities Index, experience hernia recurrence significantly sooner as compared to patients from prosperous zip codes. This study may provide evidence of the role of neighborhood and environmental factors in caring for older patients following VHR.

Ten-year outcomes following ventral hernia repair: making the case for better post-market surveillance in the USA.

BACKGROUND: We sought to identify the 10-year complication and recurrence rates and associated sociodemographic and operative characteristics associated with non-mesh versus mesh-based ventral hernia repairs (VHRs). METHODS: This was an IRB-approved (2020H0317) retrospective longitudinal study of patients undergoing mesh or non-mesh VHR from 2009-2019 at a single tertiary-care institution. The electronic medical record was used to collect sociodemographic, clinical, and intraoperative details, and early (≤ 30 days) and long-term (> 30-day) postoperative complications. Up to ten-year follow-up was obtained for long-term complications, categorized as: hernia recurrence reoperation (HRR), major complications requiring emergency surgery (MCES) (defined as non-elective operations related to the abdominal wall), and non-recurrence procedural intervention (NRPI) (defined as any procedures related to the abdominal wall, bowel, or mesh). Kaplan-Meier survival curves were obtained for each long-term complication. RESULTS: Of the 645 patients identified, the mean age at index operation was 52.51 ± 13.57 years with 50.70% female. Of the index operations, 21.24% were for a recurrence. Procedure categories included: 57.36% incisional, 37.21% non-incisional umbilical, 8.22% non-incisional epigastric, 3.88% parastomal, 0.93% diastasis recti, and 0.47% Spigelian hernias. Operative approaches included open (n = 383), laparoscopic (n = 267), and robotic (n = 21). Fascial closure (81.55%) and mesh use (66.2%) were performed in the majority of cases. Median follow-up time was 2098 days (interquartile range 1320-2806). The rate of short-term complications was 4.81% for surgical site infections, 15.04% for surgical site occurrences, and 13.64% for other complications. At 10 years, the HRR-free survival probability was 85.26%, MCES-free survival probability was 94.44%, and NRPI-free survival probability was 78.11%. CONCLUSIONS: A high proportion of patients experienced long-term recurrence and complications requiring intervention after index VHR. For many patients, a ventral hernia develops into a chronic medical condition. Improved efforts at post-market surveillance of operative approaches and mesh location and type should be undertaken to help optimize outcomes.

Calibration of Hernia-Specific Patient-Reported Outcome Measures.

INTRODUCTION: Although there are many patient-reported outcome measures used for ventral hernia (VH), disease-specific instruments, such as the Hernia-related Quality-of-Life (QoL) Survey (HerQLes) and Abdominal Hernia-Q (AHQ), have shown greater accuracy in capturing all VH-related QoL. We present a novel calibration that allows providers to convert scores between the AHQ and HerQLes, enabling better unification of QoL data. METHODS: Patients with VH were prospectively identified and simultaneously administered both the AHQ and HerQLes pre- and post-operatively. To ensure the validity of the calibration, responses were excluded if patients answered instruments on different dates or if the responses were discordant on corresponding questions within each instrument. The calibration was estimated using a linear mixed effects model, including linear and quadratic scores, timing of survey relative to surgery and their interactions as fixed effects, and patients as random effects to account for multiple surveys from the same patient. RESULTS: In total, 109 patients were included, responding to 300 pairs of surveys (112 preoperative and 188 postoperative), of which 17 (5.6%) were excluded because of discordant responses. Conversion of the HerQLes to AHQ was most accurate when including whether the survey was completed pre- or post-operatively, with a mean squared error of 0.0091. Similarly, converting the AHQ to HerQLes was most accurate when factoring in the timing of survey administration, with a mean squared error of 0.016. CONCLUSIONS: We present a novel and accurate method to convert scores between the AHQ and HerQLes. Being able to unify QoL data from different PROMs supports efforts to more broadly integrate PROMs in surgery and to understand patient-defined measures of success.

Elective ventral hernia repair provides significant abdominal wall quality of life improvements in older patients.

BACKGROUND: An increasing proportion of ventral hernia patients are over age 65. These patients are frequently offered watchful waiting rather than surgical intervention due to their frail state or perioperative risk. However, many in this age group suffer from significant quality of life impacts that are not well understood. METHODS: We performed a retrospective cohort study using data from the Abdominal Core Health Quality Collaborative (ACHQC), including adults undergoing elective ventral hernia repair from 2013 to 2019. Median differences in Hernia-Related Quality of Life Survey (HerQLes) summary scores at baseline, 30-days, 6-months, and 1 year post operatively were compared in four age categories (18-40, 40-64, 65-75, 76 +) using multivariable regression. Secondary outcomes included major post-operative complications and mortality. RESULTS: Of 6681 patients meeting inclusion criteria, 13.5% were 18-40, 55.8% were 41-64, 25.2% were 65-75, and 5% were 76 + . Patients in the 65-75 age group and those over 76 had higher mean baseline HerQLes scores (51.7 and 60.8) compared to those in the 18-40 and 41-64 groups (45 and 43.3, p < 0.01). Patients 65-75 had smaller increases in HerQLes scores at 30 days (6.7) compared to patients in the younger age groups (11.7 for 18-40; 8.3 for 41-64) and the oldest age group (8.3, p < 0.01). However, patients in the older age groups had higher overall median 1 year HerQles Scores (66.7 for 65-75; 78.3 for 76 +) compared to patients in the 18-40 and 41-64 age groups (65 and 58.3, p < 0.01). On multivariable analysis, HerQLes scores at 30 days post-surgery were decreased for patients in the 41-64 (-3.14, CE -5.89, -0.04, p = 0.03) and 65-75 (-4.53; CE -7.65, -1.41, p < 0.01) groups compared to the youngest age group, while those over 76 had no effect. CONCLUSION: Older adults undergoing ventral hernia repair demonstrate equal gains in hernia-related quality of life compared to younger patients and actually report higher quality of life scores at 30 days, 6 months and, 1 year post-surgery.

A National Evaluation of Surgeon Experiences in Telemedicine for the Care of Hernia and Abdominal Core Health Patients.

BACKGROUND: Surgeons are increasingly utilizing telemedicine to provide perioperative services to patients. Safety, satisfaction, and feasibility of these programs in general populations have been established, but it is unclear how telemedicine can be integrated into subspecialty care. We report results of a national survey related to telehealth practices among members of the Abdominal Core Health Quality Collaborative (ACHQC). METHODS: Survey responses were analyzed to determine current strategies in telemedicine utilization. Surgeon preferences, perceptions of validity, and identified barriers to implementation of telemedicine were assessed. RESULTS: Forty surgeons within the ACHQC responded, with 90% of respondents reporting use of telemedicine to deliver perioperative care to patients with hernias and abdominal core health concerns. Surgeons appeared to be more comfortable managing preoperative patients with image-confirmed diagnoses of hernias. Surgeons were universally more comfortable delivering postoperative care via telemedicine. Connectivity, patient engagement, and reimbursement were identified as potential barriers to expansion of telemedicine. Seventy-eight percent of respondents reported that they would increase telemedicine utilization if current regulations were maintained in the future. CONCLUSIONS: This study found that hernia specialists are utilizing telemedicine at a higher rate than before the COVID-19 pandemic, with surgeons reporting interest in continued use of this modality beyond the pandemic. These findings suggest that future work in telemedicine optimization may improve the quality of care that can be delivered to patients with abdominal core health concerns.

Virtual Interviews for Surgical Fellowship are an Acceptable Alternative to In-Person Interviews for Applicants and Faculty Alike.

Background: In-person interviews have traditionally been an integral part of the fellowship application process to allow faculty and applicants to interact and evaluate the intangible aspects of the matching process. COVID-19 has forced a transition away from in-person interviews to a virtual platform. This study sought to track faculty and applicant perspectives on this transition. Study Design: Prospectively collected survey data was obtained from all participants after each of 3 consecutive virtual interview days for minimally invasive surgery fellowship at a single academic institution. Results: One hundred percent (27/27 applicants and 9/9 faculty) of interview participants completed the survey. Cost (100% applicants, 77.8% faculty) was perceived as the greatest barrier to in-person interviews, and "inability to get a feel for the program/applicant" was the largest concern for virtual interviews (66.7% applicants, 88.9% faculty). After interviews, most participants strongly agreed that they were able to assess education (66.7% applicants, 77.8% faculty), clinical experience (70.4% applicants, 77.8% faculty), and research potential (70.4% applicants, 88.9% faculty) through the virtual platform. Only 44.4% of each group strongly agreed that they could assess "overall fit" equally as well. Most faculty (6/9, 66.7%), but fewer applicants (10/27, 37.0%), were willing to completely eliminate in-person interviews. Conclusion: Virtual interviews may be an acceptable alternative to in-person interviews in times of COVID-19 and beyond. Offering a virtual format may help to eliminate costs associated with in-person visits while adequately assessing the fit of a program for both applicants and faculty, though applicants still desire an in-person option.

Greatest Quality of Life Improvement in Patients With Large Ventral Hernias: An Individual Assessment of Items in the HerQLes Survey.

BACKGROUND: Ventral hernia repair (VHR) has been shown to improve overall quality of life (QOL) by the validated 12-question Hernia-Related Quality-of-Life survey (HerQLes). However, which specific aspects of quality of life are most affected by VHR have not been formally investigated. METHODS: Through retrospective analysis of the Abdominal Core Health Quality Collaborative national database, we measured the change in each individual component of the HerQLes questionnaire from a pre-operative baseline assessment to one-year postoperatively in VHR patients. RESULTS: In total, 1,875 VHR patients had completed both pre- and post-operative questionnaires from 2014-2018. They were predominately Caucasian (92.3%), 57.9 ± 12.4 Y old, and evenly gender split (50.5% male, 49.5% female, P = 0.31). Most operations were performed open (80.5%) with fewer laparoscopic (7.5%) or robotic cases (12.1%). For each of the 12 individual categories, improvement in QOL from baseline to 1-Y was found to be statistically significant (P < 0.0001). This held true with subgroup analysis of small (<2 cm), medium (2-6 cm), and large (>6 cm) hernias (P < 0.0001), though a larger improvement was seen in 8 of 12 components in hernias >6 cm (P < 0.001). Operative approach did not carry a significant effect except in medium hernias (2-6 cm), where an open approach saw a greater improvement in the "accomplish less at work" item (P = 0.02). CONCLUSIONS: VHR is associated with improvement in each of the 12 components of QOL measured in the HerQLes questionnaire, regardless of the size of their hernia. The amount of improvement, however, may be dependent on hernia size and approach.

Reducing Length of Stay Using a Robotic-assisted Approach for Retromuscular Ventral Hernia Repair: A Comparative Analysis From the Americas Hernia Society Quality Collaborative.

OBJECTIVE: The aim of this study was to compare length of stay (LOS) after robotic-assisted and open retromuscular ventral hernia repair (RVHR). BACKGROUND: RVHR has traditionally been performed by open techniques. Robotic-assisted surgery enables surgeons to perform minimally invasive RVHR, but with unknown benefit. Using real-world evidence, this study compared LOS after open (o-RVHR) and robotic-assisted (r-RVHR) approach. METHODS: Multi-institutional data from patients undergoing elective RVHR in the Americas Hernia Society Quality Collaborative between 2013 and 2016 were analyzed. Propensity score matching was used to compare median LOS between o-RVHR and r-RVHR groups. This work was supported by an unrestricted grant from Intuitive Surgical, and all clinical authors have declared direct or indirect relationships with Intuitive Surgical. RESULTS: In all, 333 patients met inclusion criteria for a 2:1 match performed on 111 r-RVHR patients using propensity scores, with 222 o-RVHR patients having similar characteristics as the robotic-assisted group. Median LOS [interquartile range (IQR)] was significantly decreased for r-RVHR patients [2 days (IQR 2)] compared with o-RVHR patients [3 days (IQR 3), P < 0.001]. No differences in 30-day readmissions or surgical site infections were observed. Higher surgical site occurrences were noted with r-RVHR, consisting mostly of seromas not requiring intervention. CONCLUSIONS: Using real-world evidence, a robotic-assisted approach to RVHR offers the clinical benefit of reduced postoperative LOS. Ongoing monitoring of this technique should be employed through continuous quality improvement to determine the long-term effect on hernia recurrence, complications, patient satisfaction, and overall cost.

Is It Time to Reconsider Postoperative Epidural Analgesia in Patients Undergoing Elective Ventral Hernia Repair?: An AHSQC Analysis.

OBJECTIVE: We aimed to evaluate the association of epidural analgesia (EA) with hospital length of stay (LOS), wound morbidity, postoperative complications, and patient-reported outcomes in patients undergoing ventral hernia repair (VHR). BACKGROUND: EA has been shown to reduce LOS in certain surgical populations. The LOS benefit in VHR is unclear. METHODS: Patients having VHR performed in the Americas Hernia Society Quality Collaborative (AHSQC) were separated into 2 comparable groups matched on several confounding factors using a propensity score algorithm: one group received postoperative EA, and the other did not. The groups were then evaluated for hospital LOS, 30-day wound morbidity, other complications, and 30-day patient-reported outcomes using pain and hernia-specific quality-of-life instruments. RESULTS: A 1:1 match was achieved and the final analysis included 763 patients receiving EA and 763 not receiving EA. The EA group had an increased LOS (5.49 vs 4.90 days; P < 0.05). The rate of wound events was similar between the groups. There was an increased risk of having any postoperative complication associated with having EA (26% vs 21%; P < 0.05). Pain intensity-scaled scores were significantly higher (worse) in the EA group versus the non-EA group (47.6 vs 44.0; P = 0.04). CONCLUSIONS: The LOS benefit of EA noted for other operations may not apply to patients undergoing VHR. Further study is necessary to determine the beneficial role of invasive pain management procedures in this group of patients with an extremely common disease state.

Heller myotomy versus Heller myotomy with Dor fundoplication for achalasia: long-term symptomatic follow-up of a prospective randomized controlled trial.

BACKGROUND: Our prior randomized controlled trial of Heller myotomy alone versus Heller plus Dor fundoplication for achalasia from 2000 to 2004 demonstrated comparable postoperative resolution of dysphagia but less gastroesophageal reflux after Heller plus Dor. Patient-reported outcomes are needed to determine whether the findings are sustained long-term. METHODS: We actively engaged participants from the prior randomized cohort, making up to six contact attempts per person using telephone, mail, and electronic messaging. We collected patient-reported measures of dysphagia and gastroesophageal reflux using the Dysphagia Score and the Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) instrument. Patient-reported re-interventions for dysphagia were verified by obtaining longitudinal medical records. RESULTS: Among living participants, 27/41 (66%) were contacted and all completed the follow-up study at a mean of 11.8 years postoperatively. Median Dysphagia Scores and GERD-HRQL scores were slightly worse for Heller than Heller plus Dor but were not statistically different (6 vs 3, p = 0.08 for dysphagia, 15 vs 13, p = 0.25 for reflux). Five patients in the Heller group and 6 in Heller plus Dor underwent re-intervention for dysphagia with most occurring more than five years postoperatively. One patient in each group underwent redo Heller myotomy and subsequent esophagectomy. Nearly all patients (96%) would undergo operation again. CONCLUSIONS: Long-term patient-reported outcomes after Heller alone and Heller plus Dor for achalasia are comparable, providing support for either procedure.

Prospective evaluation of poly-4-hydroxybutyrate mesh in CDC class I/high-risk ventral and incisional hernia repair: 18-month follow-up.

BACKGROUND: Long-term resorbable mesh represents a promising technology for complex ventral and incisional hernia repair (VIHR). Preclinical studies indicate that poly-4-hydroxybutyrate (P4HB) resorbable mesh supports strength restoration of the abdominal wall. This study evaluated outcomes of high-risk subjects undergoing VIHR with P4HB mesh. METHODS: This was a prospective, multi-institutional study of subjects undergoing retrorectus or onlay VIHR. Inclusion criteria were CDC Class I, defect 10-350 cm2, ≤ 3 prior repairs, and ≥ 1 high-risk criteria (obesity (BMI: 30-40 kg/m2), active smoker, COPD, diabetes, immunosuppression, coronary artery disease, chronic corticosteroid use, hypoalbuminemia, advanced age, and renal insufficiency). Physical exam and/or quality of life surveys were performed at regular intervals through 18 months (to date) with longer-term, 36-month follow-up ongoing. RESULTS: One hundred and twenty-one subjects (46M, 75F) with an age of 54.7 ± 12.0 years and BMI of 32.2 ± 4.5 kg/m2 (mean ± SD), underwent VIHR. Comorbidities included the following: obesity (n = 95, 78.5%), hypertension (n = 72, 59.5%), cardiovascular disease (n = 42, 34.7%), diabetes (n = 40, 33.1%), COPD (n = 34, 28.1%), malignancy (n = 30, 24.8%), active smoker (n = 28, 23.1%), immunosuppression (n = 10, 8.3%), chronic corticosteroid use (n = 6, 5.0%), advanced age (n = 6, 5.0%), hypoalbuminemia (n = 3, 2.5%), and renal insufficiency (n = 1, 0.8%). Hernia types included the following: primary ventral (n = 17, 14%), primary incisional (n = 54, 45%), recurrent ventral (n = 15, 12%), and recurrent incisional hernia (n = 35, 29%). Defect and mesh size were 115.7 ± 80.6 and 580.9 ± 216.1 cm2 (mean ± SD), respectively. Repair types included the following: retrorectus (n = 43, 36%), retrorectus with additional myofascial release (n = 45, 37%), onlay (n = 24, 20%), and onlay with additional myofascial release (n = 8, 7%). 95 (79%) subjects completed 18-month follow-up to date. Postoperative wound infection, seroma requiring intervention, and hernia recurrence occurred in 11 (9%), 7 (6%), and 11 (9%) subjects, respectively. CONCLUSIONS: High-risk VIHR with P4HB mesh demonstrated positive outcomes and low incidence of hernia recurrence at 18 months. Longer-term 36-month follow-up is ongoing.

Surgical Transfer Decision Making: How Regional Resources are Allocated in a Regional Transfer Network.

BACKGROUND: Tertiary care centers often operate above capacity, limiting access to emergency surgical care for patients at nontertiary facilities. For nontraumatic surgical emergencies there are no guidelines to inform patient selection for transfer to another facility. Such decisions may be particularly difficult for gravely ill patients when the benefits of transfer are uncertain. METHODS: To characterize surgeons' decision-making strategies for transfer, a qualitative analysis of semistructured interviews was conducted with 16 general surgeons who refer and accept patients within a regional transfer network. Interviews included case-based vignettes about surgical patients with high comorbidity, multisystem organ failure, and terminal conditions. An inductive coding strategy was used, followed by performance of a higher-level analysis to characterize important themes and trends. RESULTS: Surgeons at outlying hospitals seek transfer when the resources to care for patients' surgical needs or comorbid conditions are unavailable locally. In contrast, surgeons at the tertiary center accept all patients regardless of outcome or resource considerations. Bed availability at the tertiary care center restricts transfer capacity, harming patients who cannot be transferred. Surgeons sometimes transfer dying patients in order to exhaust all treatment options or appease families, but they are conflicted about the value of transfer, which displaces patients from their local communities and limits access to tertiary care for others. CONCLUSION: Decisions to transfer surgical patients are complex and require comprehensive understanding of local capacity and regional resources. Current decision-making strategies fail to optimize patient selection for transfer and can inappropriately allocate scarce tertiary care beds.

Multicenter, Prospective, Longitudinal Study of the Recurrence, Surgical Site Infection, and Quality of Life After Contaminated Ventral Hernia Repair Using Biosynthetic Absorbable Mesh: The COBRA Study.

OBJECTIVE: The aim of the study was to evaluate biosynthetic absorbable mesh in single-staged contaminated (Centers for Disease Control class II and III) ventral hernia (CVH) repair over 24 months. BACKGROUND: CVH has an increased risk of postoperative infection. CVH repair with synthetic or biologic meshes has reported chronic biomaterial infections and high hernia recurrence rates. METHODS: Patients with a contaminated or clean-contaminated operative field and a hernia defect at least 9 cm had a biosynthetic mesh (open, sublay, retrorectus, or intraperitoneal) repair with fascial closure (n = 104). Endpoints included overall Kaplan-Meier estimates for hernia recurrence and postoperative wound infection rates at 24 months, and the EQ-5D and Short Form 12 Health Survey (SF-12). Analyses were conducted on the intent-to-treat population, and health outcome measures evaluated using paired t tests. RESULTS: Patients had a mean age of 58 years, body mass index of 28 kg/m, 77% had contaminated wounds, and 84% completed 24-months follow-up. Concomitant procedures included fistula takedown (n = 24) or removal of infected previously placed mesh (n = 29). Hernia recurrence rate was 17% (n = 16). At the time of CVH repair, intraperitoneal placement of the biosynthetic mesh significantly increased the risk of recurrences (P ≤ 0.04). Surgical site infections (19/104) led to higher risk of recurrence (P < 0.01). Mean 24-month EQ-5D (index and visual analogue) and SF-12 physical component and mental scores improved from baseline (P < 0.05). CONCLUSIONS: In this prospective longitudinal study, biosynthetic absorbable mesh showed efficacy in terms of long-term recurrence and quality of life for CVH repair patients and offers an alternative to biologic and permanent synthetic meshes in these complex situations.

Current trends in the practice of endoscopy among surgeons in the USA.

BACKGROUND: The diagnostic and therapeutic roles for endoscopic intervention are expanding. To continue emphasis on endoscopy in surgical training, The Society of American Gastrointestinal and Endoscopic Surgeons has developed the Fundamentals of Endoscopic Surgery (FES) course to standardize and assess endoscopy training. However, little demographic information exists about the current practice of endoscopy by general surgeons and how to best integrate endoscopic skills into surgical training. METHODS: A survey to collect data regarding the current practice patterns of endoscopy was sent to surgeons with a valid email address in the American Medical Association masterfile. Information regarding the type of training (academic vs. community general surgery residency) and current practice environment (academic medical center vs. community hospital) was collected. The respondents' current practice volume of upper endoscopy and colonoscopy over the prior year was stratified into three groups: rare (<1 per month), moderate (1-10 per month), and frequent (>10 per month). Pearson's Chi-squared test was used to analyze the data. RESULTS: The survey was sent to 9902 general surgeons. There were 767 who provided answers regarding their current practice of endoscopy. Mean time in practice was 18 ± 10 years, 87 % were male, and 83 % practiced in a metropolitan area. Respondents who trained at academic general surgery programs were less likely than those at community programs to frequently perform colonoscopy (17.3 vs. 27.9 %, p < 0.05) and upper endoscopy (11.8 vs. 17.1 %, p < 0.05). Those who currently practice in academic medical centers were also less likely to be frequent performers of colonoscopy (5.6 vs. 24.7 %, p < 0.05) and upper endoscopy (9.8 vs. 14.8 %, p < 0.05) than those who practice at community hospitals. CONCLUSIONS: The type of residency training and current practice setting of general surgeons has a significant influence on the volume of endoscopic procedures performed. This study identifies areas where more emphasis on endoscopic skills training is needed, such as FES.

Primary fascial closure during laparoscopic ventral hernia repair does not reduce 30-day wound complications.

BACKGROUND: Laparoscopic ventral hernia repair (LVHR) is associated with decreased wound morbidity compared to open repair. It remains unclear whether primary fascial closure (PFC) offers any benefit in reducing postoperative seroma compared to bridged repair. We hypothesized that PFC would have no effect on seroma formation following LVHR. METHODS: A retrospective cohort study was performed using data from the prospectively maintained Americas Hernia Society Quality Collaborative. All patients undergoing LVHR from 2013 to 2016 were included. The primary outcome was seroma formation, diagnosed either clinically or radiographically. Secondary outcomes included surgical site infections (SSI), surgical site occurrences (SSO), and SSO requiring intervention. Patient characteristics and outcomes were compared between groups with univariate analysis using Pearson's chi-squared or Wilcoxon tests. Multivariable logistic regression controlling for patient and hernia characteristics was then performed to investigate the independent effect of PFC on seroma formation. RESULTS: 1280 patients were included in the study. 69% (n = 887) underwent PFC. Patients undergoing bridged repairs had slightly larger defects and were more likely to have a recurrent hernia. The overall rate of seroma formation was 10.4% (n = 133). There was no association on univariate analysis between PFC and wound complications. Similarly, on multivariable analysis, PFC had no significant effect on the risk of seroma formation (OR 0.87, 95% CI 0.58-1.31). CONCLUSIONS: PFC does not decrease the risk of short-term wound complications. Given that prior studies have also suggested no difference in hernia recurrence, PFC does not appear to improve postoperative outcomes for patients undergoing LVHR.

Cancer Survivorship: Defining the Incidence of Incisional Hernia After Resection for Intra-Abdominal Malignancy.

BACKGROUND: Cancer survivorship focuses largely on improving quality of life. We aimed to determine the rate of ventral incisional hernia (VIH) formation after cancer resection, with implications for survivorship. METHODS: Patients without prior VIH who underwent abdominal malignancy resections at a tertiary center were followed up to 2 years. Patients with a viewable preoperative computed tomography (CT) scan and CT within 2 years postoperatively were included. Primary outcome was postoperative VIH on CT, reviewed by a panel of surgeons uninvolved with the original operation. Factors associated with VIH were determined using Cox proportional hazards regression. RESULTS: 1847 CTs were reviewed among 491 patients (59 % men), with inter-rater reliability 0.85 for the panel. Mean age was 60 ± 12 years; mean follow-up time 13 ± 8 months. VIH occurred in 41 % and differed across diagnoses: urologic/gynecologic (30 %), colorectal (53 %), and all others (56 %) (p < 0.001). Factors associated with VIH (adjusting for stage, age, adjuvant therapy, smoking, and steroid use) included: incision location [flank (ref), midline, hazard ratio (HR) 6.89 (95 %CI 2.43-19.57); periumbilical, HR 6.24 (95 %CI 1.84-21.22); subcostal, HR 4.55 (95 %CI 1.51-13.70)], cancer type [urologic/gynecologic (ref), other {gastrointestinal, pancreatic, hepatobiliary, retroperitoneal, and others} HR 1.86 (95 %CI 1.26-2.73)], laparoscopic-assisted operation [laparoscopic (ref), HR 2.68 (95 %CI 1.44-4.98)], surgical site infection [HR 1.60 (95 %CI 1.08-2.37)], and body mass index [HR 1.06 (95 %CI 1.03-1.08)]. CONCLUSIONS: The rate of VIH after abdominal cancer operations is high. VIH may impact cancer survivorship with pain and need for additional operations. Further studies assessing the impact on QOL and prevention efforts are needed.

Insurance status influences emergent designation in surgical transfers.

BACKGROUND: There is a perception among surgeons that hospitals disproportionately transfer unfavorably insured patients for emergency surgical care. Emergency medical condition (EMC) designation mandates referral center acceptance of patients for whom transfer is requested. We sought to understand whether unfavorably insured patients are more likely to be designated as EMCs. MATERIALS AND METHODS: A retrospective cohort study was performed on patient transfers from a large network of acute care facilities to emergency surgery services at a tertiary referral center from 2009-2013. Insurance was categorized as favorable (commercial or Medicare) or unfavorable (Medicaid or uninsured). The primary outcome, transfer designation as EMC or non-EMC, was evaluated using multivariable logistic regression. A secondary analysis evaluated uninsured patients only. RESULTS: There were 1295 patient transfers in the study period. Twenty percent had unfavorable insurance. Favorably insured patients were older with fewer nonwhite, more comorbidities, greater illness severity, and more likely transferred for care continuity. More unfavorably insured patients were designated as EMCs (90% versus 84%, P < 0.01). In adjusted models, there was no association between unfavorable insurance and EMC transfer (odds ratio [OR], 1.61; 95% confidence interval [CI], 0.98-2.69). Uninsured patients were more likely to be designated as EMCs (OR, 2.27; CI, 1.08-4.77). CONCLUSIONS: The finding that uninsured patients were more likely to be designated as EMCs suggests nonclinical variation that may be mitigated by clearer definitions and increased interfacility coordination to identify patients requiring transfer for EMCs.
