Am J Surg 2024; 233:100-107. [PMID: 38494357 DOI: 10.1016/j.amjsurg.2024.02.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 01/29/2024] [Accepted: 02/15/2024] [Indexed: 03/19/2024]
Abstract
BACKGROUND Many surgical risk assessment tools emphasize patient-specific risk factors. Our objective was to use a hernia-specific database to assess risk factors of complications in ventral hernia repair (VHR) focusing on hernia-specific and procedural factors. METHODS The ACHQC database was queried for elective VHR in adults from 2012 to 2023. Primary outcome was overall 30-day complications. Multivariable logistic regression was used for analysis. RESULTS 41,526 VHR were included. The rate of 30-day complications was 18%, surgical site infection 3%, surgical site occurrence requiring procedural intervention 4%, readmission 4%, reoperation 2%, and mortality 0.2%. Multivariable analysis demonstrated that BMI, ASA, frailty, COPD, anticoagulants, defect width, incisional and recurrent hernias, presence of stoma or prior mesh, prior abdominal wall infection, non-clean wound, operative time, open approach and myofascial release were associated with 30-day complications (OR = 1.01-1.66). Preoperative chlorhexidine, bowel preparation and fascial closure were associated with lower complication risk (OR = 0.70-0.89). CONCLUSION Hernia and procedural risk factors are associated with early complications following elective VHR. These factors need to be included in surgical risk assessment tools, to supplement patient-specific factors.

Deep learning model utilizing clinical data alone outperforms image-based model for hernia recurrence following abdominal wall reconstruction with long-term follow up. Surg Endosc 2024:10.1007/s00464-024-10980-y. [PMID: 38862826 DOI: 10.1007/s00464-024-10980-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 06/02/2024] [Indexed: 06/13/2024]
Abstract
BACKGROUND Deep learning models (DLMs) using preoperative computed tomography (CT) imaging have shown promise in predicting outcomes following abdominal wall reconstruction (AWR), including component separation, wound complications, and pulmonary failure. This study aimed to apply these methods in predicting hernia recurrence and to evaluate if incorporating additional clinical data would improve the DLM's predictive ability. METHODS Patients were identified from a prospectively maintained single-institution database. Those who underwent AWR with available preoperative CTs were included, and those with < 18 months of follow up were excluded. Patients were separated into a training (80%) set and a testing (20%) set. A DLM was trained on the images only, and another DLM was trained on demographics only: age, sex, BMI, diabetes, and history of tobacco use. A mixed-value DLM incorporated data from both. The DLMs were evaluated by the area under the curve (AUC) in predicting recurrence. RESULTS The models evaluated data from 190 AWR patients with a 14.7% recurrence rate after an average follow up of more than 7 years (mean ± SD: 86 ± 39 months; median [Q1, Q3]: 85.4 [56.1, 113.1]). Patients had a mean age of 57.5 ± 12.3 years and were majority (65.8%) female with a BMI of 34.2 ± 7.9 kg/m2. There were 28.9% with diabetes and 16.8% with a history of tobacco use. The AUCs for the imaging DLM, clinical DLM, and combined DLM were 0.500, 0.667, and 0.604, respectively. CONCLUSIONS The clinical-only DLM outperformed both the image-only DLM and the mixed-value DLM in predicting recurrence. While all three models were poorly predictive of recurrence, the clinical-only DLM was the most predictive. These findings may indicate that imaging characteristics are not as useful for predicting recurrence as they have been for other AWR outcomes. Further research should focus on understanding the imaging characteristics that are identified by these DLMs and expanding the demographic information incorporated in the clinical-only DLM to further enhance the predictive ability of this model.

Abstract
PURPOSE The radiographic rectus width to hernia width ratio (RDR) has been shown to predict ability to close fascial defect without additional myofascial release in open Rives-Stoppa abdominal wall reconstruction (AWR), but it has not been studied in robotic AWR. We aimed to examine various CT measurements to determine their usability in predicting the need for transversus abdominis release (TAR) in robotic AWR. METHODS We performed a single-center retrospective review of 137 patients with midline ventral hernias over a 5-year period who underwent elective robotic retrorectus AWR. We excluded patients with M1 or M5 hernias, lateral/flank hernias, and hybrid repairs. The CT measurements included hernia width (HW), hernia width/abdominal width ratio (HW/AW), and RDR. Univariate, multivariate and area under the curve (AUC) analyses were performed. RESULTS 58/137 patients required TAR (32 unilateral, 26 bilateral). Patients undergoing TAR had a significantly higher average HW and HW/AW and lower RDR. Multivariate analysis revealed that prior hernia repair was independently associated with need for TAR (p = 0.03). ROC analysis and AUC values showed acceptable diagnostic ability of HW, HW/AW and RDR in predicting need for TAR. Cutoffs of RDR ≤ 2, HW/AW > 0.3, and HW > 10 cm yielded high specificity in determining need for any TAR (97.5% vs. 96.2% vs. 92.4%) or bilateral TAR (95.5% vs. 94.6% vs. 92.8%). CONCLUSION History of prior hernia repair was a risk factor for robotic TAR. CT measurements have some predictive value in determining need for TAR in robotic AWR. Further prospective analysis is needed in this patient population.

Abstract
INTRODUCTION An incisional hernia is a common complication after abdominal surgery. Mesh fixation and fascial closure are crucial aspects of repairing incisional hernias. The aim of this study is to investigate the effect of adding a buttressing suture in the center of the mesh in onlay incisional hernia repair on recurrence. METHODS This retrospective study analyzed 157 patients who underwent elective repair of incisional hernia at Tokat State Hospital between January 2013 and January 2020. The study examined age, gender, comorbidity, smoking, hernia type, defect size, operative time, follow-up time, recurrence, and chronic pain. The patients were divided into two groups based on the type of buttressing suture used: normal and buttressing suture. Recurrence was defined as the reappearance of a hernia at the site of a previous surgery. RESULTS The study included 126 patients, with 61 (48.4%) in the control group and 55 (51.6%) in the buttressing suture group. Ten patients reported recurrence, with eight (13.1%) in the control group and two (3.1%) in the buttressing suture group. The difference in recurrence between the groups was statistically significant (p=0.038). The control group had an operative time of 58.79±13.23 minutes, while the buttressing suture group had an operative time of 62.12±13.51 minutes. The statistical analysis did not reveal any significant difference between the two groups (p=0.091). Out of the patients with chronic pain, two (33%) were in the control group and four (66%) were in the buttressing suture group. The incidence of chronic pain did not differ significantly between the two groups (p=0.52). CONCLUSION In incisional hernia repair, the use of buttressing sutures with mesh in incisional hernia repair resulted in decreased recurrence rates without increasing chronic pain or affecting operative time.

Abstract
Background: The COVID-19 pandemic has transformed health care delivery through the rise of telehealth solutions. Though telemedicine-based care has been identified as safe and feasible in postoperative care, data on initial surgical consultations in the preoperative setting are lacking. We sought to compare patient characteristics, anticipated downstream care utilization, and patient-reported experiences (PREs) for in-person versus telemedicine-based care conducted for initial consultation encounters at a hernia and abdominal wall center. Methods: Patients evaluated at an abdominal wall reconstruction center from August 2021 to August 2022 were prospectively surveyed. Patient characteristics, anticipated downstream care utilization, and PREs were compared. Results: Of the 176 respondents, 50.6% (n = 89) utilized telemedicine-based care and had similar demographic and disease characteristics to those receiving in-person care. Telemedicine-based care saved a median of 47 min [interquartile range 20-112.5 min] of round-trip travel time per patient, with 10.1% of encounters resulting in supplemental in-person evaluation. A large proportion of telemedicine-based and in-person encounters resulted in recommendations for operative intervention, 38.2% versus 55.2%, respectively. Indirect costs of care were significantly lower for patients utilizing telemedicine-based services. Patient satisfaction related to encounters was non-inferior to in-person care. Overall, the majority of patients responded that they preferred future care to be delivered via telemedicine-based services, if offered. Conclusions: Preoperative telemedicine-based care was associated with significant cost-savings over in-person care related with comparable patient satisfaction. Health systems should continue to dedicate resources to optimizing and expanding perioperative telemedicine capabilities.

Abstract
INTRODUCTION Ventral wall hernia often causes significant morbidity and requires complex abdominal wall reconstruction (AWR). This study aims to determine whether subcutaneous abdominal fat thickness (AFT) measured with preoperative CT scans could predict postoperative outcomes in patients undergoing AWR. METHODS A retrospective cohort study was conducted on all patients who underwent AWR at our institution between 2009 and 2021, with a minimum follow-up of 12 months. Using preoperative CT scans, AFT was measured at the xiphoid process, umbilicus, and pubic tubercle, as well as the hernia dimensions. Demographic, operative, and surgical outcome data were also collected and analyzed using statistical tests. RESULTS The results showed that 9 of 101 patients (8.9%) experienced hernia recurrence. Smoking was associated with an increased risk of hernia recurrence (p < 0.001) with a predictive odds ratio (OR) of 18.27 (p = 0.041). Increased AFT at the xiphoid (p = 0.005), umbilicus (p < 0.001), and pubic tubercle (p < 0.001) were also associated with hernia recurrence and risk of infection. Only AFT at the pubic tubercle reached significance in the regression model predicting recurrence (OR=1.10; p = 0.030) and infection (OR=1.04; p = 0.021). A cut-off value of 67 mm was associated with a positive predictive value of 42.14% (sensitivity of 67% and specificity of 91%). Hernia defect area was not associated with risk of recurrence or infection. CONCLUSIONS Smoking and increased AFT at the pubic tubercle are significant predictive factors for recurrence and infection in patients undergoing AWR, and preoperative optimization should focus on reducing these factors.

CT-measured hernia parameters can predict component separation: a cross-sectional study from China. Hernia 2023:10.1007/s10029-023-02761-8. [PMID: 36934216 DOI: 10.1007/s10029-023-02761-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 02/12/2023] [Indexed: 03/19/2023]
Abstract
PURPOSE Currently, there are no reliable preoperative methods for predicting component separation (CS) during incisional hernia repair. By quantitatively measuring preoperative computed tomography (CT) imaging, we aimed to assess the value of hernia defect size, abdominal wall muscle quality, and hernia volume in predicting CS. METHODS The data of 102 patients who underwent open Rives-Stoppa retro-muscular mesh repair for midline incisional hernia between January 2019 and March 2022 were retrospectively analyzed. The patients were divided into two groups: ''CS group'' patients who required CS to attempt fascial closure, and ''non-CS'' group patients who required only Rives-Stoppa retro-muscular release to achieve fascial closure. Hernia defect width, hernia defect angle, rectus width, abdominal wall muscle area and CT attenuation, hernia volume (HV), and abdominal cavity volume (ACV) were measured on CT images. The rectus width to defect width ratio (RDR), HV/ACV, and HV/peritoneal volume (PV; i.e., HV + ACV) were calculated. Differences between the indices of the two groups were compared. Logistic regression models were applied to analyze the relationships between the above CT parameters and CS. Receiver operator characteristic (ROC) curves were generated to evaluate the potential utility of CT parameters in predicting CS. RESULTS Of the102 patients, 69 were in the non-CS group and 33 were in the CS group. Compared with the non-CS group, hernia defect width (P < 0.001), hernia defect angle (P < 0.001), and hernia volume (P < 0.001) were larger in the CS group, while RDR (P < 0.001) was smaller. The abdominal wall muscle area in the CS group was slightly greater than that in the non-CS group (P = 0.046), and there was no significant difference in the CT attenuation of the abdominal wall muscle between the two groups (P = 0.089). Multivariate logistic regression identified hernia defect width (OR 1.815, 95% CI 1.428-2.308, P < 0.001), RDR (OR 0.018, 95% CI 0.003-0.106, P < 0.001), hernia defect angle (OR 1.077, 95% CI 1.042-1.114, P < 0.001), hernia volume (OR 1.002, 95% CI 1.001-1.003, P < 0.001), and CT attenuation of abdominal wall muscle (OR 0.962, 95% CI 0.927-0.998, P = 0.037) as independent predictors of CS. Hernia defect width was the best predictor for CS, with a cut-off point of 9.2 cm and an area under the curve (AUC) of 0.890. The AUCs of RDR, hernia defect angle, hernia volume, and abdominal wall muscle CT attenuation were 0.843, 0.812, 0.747, and 0.572, respectively. CONCLUSION Quantitative CT measurements are of great value for preoperative prediction of CS. Hernia defect size, hernia volume, and the CT attenuation of abdominal wall muscle are all preoperative predictive indicators of CS.

Preoperative botulinum toxin A (BTA) injection versus component separation techniques (CST) in complex abdominal wall reconstruction (AWR): A propensity-scored matched study. Surgery 2023; 173:756-764. [PMID: 36229258 DOI: 10.1016/j.surg.2022.07.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 06/14/2022] [Accepted: 07/05/2022] [Indexed: 01/01/2023]
Abstract
BACKGROUND Complete fascial closure significantly reduces recurrence rates and wound complications in abdominal wall reconstruction. While component separation techniques have clear effectiveness in closing large abdominal wall defects, preoperative botulinum toxin A has emerged as an adjunct to aid in fascial closure. Few data exist comparing preoperative botulinum toxin A to component separation techniques, and the aim was to do so in a matched study. METHODS A prospective, single-center, hernia-specific database was queried, and a 3:1 propensity-matched study of patients undergoing open abdominal wall reconstruction from 2016 to 2021 with botulinum toxin A versus component separation techniques was performed based on body mass index, defect width, hernia volume, and Centers for Disease Control and Prevention wound classification. Demographics, operative characteristics, and outcomes were evaluated. RESULTS Matched patients included 105 component separation techniques and 35 botulinum toxin A. There was no difference in tobacco use, diabetes, or body mass index (all P > .5). Hernia defects and volume were large for both the component separation techniques and botulinum toxin A groups (mean size: component separation techniques 286.2 ± 179.9 cm2 vs botulinum toxin A 289.7 ± 162.4 cm2; P = .73) (mean volume: 1,498.3 + 2,043.4 cm3 vs 2,914.7 + 6,539.4 cm3; P = .35). Centers for Disease Control and Prevention wound classifications were equivalent (CDC3 and 4%-39.1% vs 40.0%; P = .97). Component separation techniques were more frequently performed in European Hernia Society M1 hernias (21% vs 2.9%; P = .01). The botulinum toxin A group had fewer surgical site occurrences (32.4% vs 11.4%; P = .02) and surgical site infections (11.7% vs 0%; P = .04). In multivariate analysis, botulinum toxin A was associated with lower rates of surgical site occurrences (odds ratio = 5.3; 95% confidence interval [1.4-34.4]). There was no difference in fascial closure (90.5% vs 100%; P = .11) or recurrence (12.4% vs 2.9%; P = .10) with follow-up (22.8 + 29.7 vs 9.8 + 12.7 months; P = .13). CONCLUSION In a matched study comparing patients with botulinum toxin A versus component separation techniques, there was no difference in fascial closure rates or in hernia recurrence between the 2 groups. Preoperative botulinum toxin A can achieve similar outcomes as component separation techniques, while decreasing the frequency of surgical site occurrences.

Abstract
BACKGROUND Hernias can present with unique challenges when it comes to management and repair. Prediction models can be a useful tool for clinicians to better anticipate and understand the severity of a hernia, the type of surgical technique, or presurgical planning that may be required to treat the patient, and the risk of complications. Our goal is to evaluate and consolidate prediction models in hernia repair present in the literature for which physicians can reference to best improve patient outcomes and postoperative management. METHODS We performed a literature search in PubMed using keywords, "rectus width to defect width ratio," "predicting myofascial release," "computed tomography hernia repair prediction," "component separation radiology prediction hernia," "fat volume and hernia repair," "body morphometrics and Query hernia repair," "body morphometrics and reherniation," "computed tomography findings and risk of emergency hernia repair," "loss of domain and hernia radiology," and "volumetry and hernia repair." We searched for publications that used radiographic parameters to predict hernia severity, interventions, and outcomes. RESULTS Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), we found twenty-three studies related to prediction models in hernia repair published between 2000 and 2021. We summarized studies pertaining to predicting acute care, predicting operative planning with loss of domain and component separation, predicting complications, paraesophageal hernia predictions, and predicting postoperative respiratory complications. CONCLUSION Radiographic prediction models can be an objective and efficient way for surgeons to analyze hernias and better understand a patient's situation so that they can inform patients about the best treatment options and the risk of complications.

Comparison of two-dimensional measurement with three-dimensional volume rendering for the assessment of loss of domain in incisional hernia patients. Hernia 2022; 27:379-385.

Abstract
PURPOSE We aimed to compare simple two-dimensional (2D) measurement with comprehensive three-dimensional (3D) volume rendering to determine loss of domain (LOD), a clinically important decision-making feature for incisional hernia repair. METHODS In this single-center retrospective study, we analyzed the CT scans of a consecutive cohort of adult patients with a midline incisional hernia. The hernia sac- and abdominal cavity volumes were obtained by two different methods. The 2D method estimated the volumes using the corresponding height, width, and depth. The 3D method comprised of a volume rendering tool. For both methods, LOD was calculated according to the Sabbagh ratio (hernia sac volume / (hernia sac volume + abdominal cavity volume)). Taking the 3D method as the reference standard, the performance of the 2D method was expressed as positive predictive value (PPV) and negative predictive value (NPV) for LOD of more than- and less than 20%. The agreement between both methods was expressed as Cohen's kappa coefficient (kappa). RESULTS We analyzed 92 CT scans. Agreement between both methods was high (kappa = 0.854, p = 0.0001); all 67 measurements for which the 2D method assessed LOD to be less than 20% were correctly classified (NPV = 100%), and 20 of 25 measurements for which the 2D method assessed LOD to be more than 20% were correctly classified (PPV = 80%). CONCLUSIONS The 2D method can exclude patients from perioperative actions needed for a more complex hernia. Since this method is easy to use and less time-consuming, it seems useful for the routine radiological assessment of LOD in clinical practice.

Abstract
Introduction: Perioperative telemedicine services have increasingly been utilized for ambulatory care, although concerns exist regarding the feasibility of virtual consultations for older patients. We sought to review telemedicine encounters for geriatric patients evaluated at a hernia repair and abdominal wall reconstruction center. Methods: A retrospective review of telemedicine encounters between May 2020 and May 2021 was performed. Patient characteristics and encounter-specific outcomes were compared among geriatric (older than65 years old) and nongeriatric patients. Clinical care plans for encounters were reviewed to determine potential downstream care utilization. Patient-derived benefits related to time saved in travel time was calculated using geo-mapping. Outcomes for postoperative encounters were assessed to determine if complication rates differed between geriatric and nongeriatric populations. Results: A total of 313 telemedicine encounters (geriatric: 41.9%) were conducted among 251 patients. Reviewing preoperative factors for hernia care, geriatric patients presented with higher rates of recurrent or incisional hernias (87.9% vs. 70.7%, p < 0.01). Potential travel time was longer for geriatric patients (104 min vs. 42 min, p = 0.03) in the preoperative setting. No differences in clinical care plans were found. Only 8.6% of preoperative encounters resulted in recommendations for supplemental in-person evaluation. Operative plans were coordinated for 42.5% of all preoperative telemedicine encounters. There was no difference in complication rate between geriatric and nongeriatric patients (p > 0.05) in the postoperative setting, with no complications directly attributable to telemedicine-based care. Conclusions: Telemedicine-based evaluations appear to function well among geriatric patients seeking hernia repair and abdominal wall reconstruction. Clinical care plans rendered following telemedicine-based encounters are appropriate with a low rate of supplemental in-person evaluations. Telemedicine use resulted in significantly more time saved in commuting to and from clinic for geriatric patients.

Abstract
Purpose: Several guidelines have been published in recent years to guide the clinician in ventral hernia repair. This review distils this advice, critically assesses their evidence base, and proposes avenues for future study. Methods: A PUBMED search identified four guidelines addressing midline ventral hernia repair published by major surgical societies between 2016 and 2020. The studies used to inform the advice have been critically appraised, including 20 systematic reviews/meta-analyses, 10 randomized controlled trials, 32 cohort studies, and 14 case series. Results: Despite a lack of randomized controlled trials, case heterogeneity, and variation in outcome reporting, key themes have emerged. Preoperative computed tomography scan assesses defect size, loss of domain, and the likely need for component separation. Prehabilitation, frailty assessment, and risk stratification are beneficial in complex cases. Minimally invasive component separation techniques, Botox injection, and progressive pneumoperitoneum represent novel techniques to promote closure of large fascial defects. Rives-Stoppa sublay mesh repair has become the "gold" standard for open and minimally invasive repairs. Laparoscopic repair promotes early return to functional status. The enhanced-view totally extraperitoneal approach facilitates laparoscopic sublay mesh placement, avoiding mesh contact with viscera. Robotic techniques continue to evolve, although the evidence at present remains immature. Synthetic mesh is recommended for use in clean and clean-contaminated cases. However, optimism regarding the use of biologic and biosynthetic meshes in the contaminated setting has waned. Conclusions: Surgical techniques in ventral hernia repair have advanced in recent years. High-quality data has struggled to keep pace; rigorous clinical trials are required to support the surgical innovation.

Abstract
BACKGROUND Perioperative telemedicine use has increased as a result of the COVID-19 pandemic and may improve access to surgical care. However, studies assessing outcomes in populations at risk for digital-health disparities are lacking. We sought to characterize the pre- and postoperative outcomes for rural patient populations being assessed for hernia repair and abdominal wall reconstruction with telehealth. METHODS Patients undergoing telehealth evaluation from March 2020 through May 2021 were identified. Rurality was identified by zip code of residence. Rural and urban patients were compared based on demographics, diagnosis, treatment plan, and visit characteristics and outcomes. Downstream care use related to supplementary in-person referral, and diagnostic testing was assessed. RESULTS Three hundred-seventy-three (196 preoperative, 177 postoperative) telehealth encounters occurred during the study period (rural: 28% of all encounters). Rural patients were more likely to present with recurrent or incisional hernias (90.0 vs 72.7%, p = 0.02) and advanced comorbidities (American Society of Anesthesiologists status score > 2: 73.1 vs 52.1%, p = 0.009). Rural patients derived significant benefits related to time saved commuting, with median distances of 299 and 293 km for pre- and postoperative encounters, respectively. Downstream care use was 6.1% (N = 23) for additional in-person evaluations and 3.4% (N = 13) for further diagnostic testing, with no difference by rurality. CONCLUSIONS Perioperative telehealth can safely be implemented for rural populations seeking hernia repair and may be an effective method for reducing disparities. Downstream care use related to additional in-person referral or diagnostic testing was minimally impacted in both the preoperative and postoperative settings. These findings suggest that rurality should not deter surgeons from providing telemedicine-based surgical consultation for hernia repair.

Abstract
Purpose Telemedicine has emerged as a viable option to in-person visits for the evaluation and management of surgical patients. Increased integration of telemedicine has allowed for greater access to care for specific patient populations but relative outcomes are unstudied. Given these limitations, we sought to evaluate the efficacy of telemedicine-based new patient preoperative encounters in comparison to in-person encounters. Methods We performed a retrospective analysis of adult patients undergoing new patient evaluations from April 2020 to October 2021. Telemedicine visits consist of both video and telephone-based encounters. Visit types, patient demographics, preoperative diagnosis, travel time to the hospital, and prior imaging availability were reviewed. Results A total of 276 new patient encounters were conducted (n = 108, 39% telemedicine). Indications for evaluation included inguinal hernia (n = 81, 30%), ventral hernia (n = 149, 54%) and groin or abdominal pain (n = 30, 11%). Patients undergoing telehealth evaluations were more likely to have greater travel distance to the hospital (91 km vs 29 km, p = 0.002) and have CT image-confirmed diagnoses at the initial visit (73 vs 47%, p < 0.001). Patients who were evaluated for a recurrent or incisional hernia were more likely to be seen through a telemedicine encounter (69 vs 45%, p < 0.001). Conclusions We report the efficacy of telemedicine-based consultations for new patient preoperative evaluations related to hernia repair and abdominal wall reconstruction. Telemedicine is a useful modality for preoperative evaluation of new patients with hernia and advanced abdominal wall reconstruction needs. Understanding this patient population will allow us to optimize telemedicine encounters for new patients and improve access to care for patients in remote locations.

Abstract
PURPOSE The treatment of giant incisional hernia (IH) with loss of domain (LOD, IHLD) is considerably challenging due to technical difficulties and subsequent post-operative complications. These post-operative risks may be anticipated by calculating the abdominal cavity (AC) volume (ACV) and the IH volume (IHV) on the preoperative CT-scans, using the AC and IH dimensions (Tanaka's method) or using tridimensional volumetry (Sabbagh's method). These techniques are often time-consuming and require specific softwares. The aim of the present study was to develop a simple method to rapidly obtain the LOD-ratio on the preoperative CT-Scan. METHODS The CT-scans (n = 89) of patients with IHLD were retrospectively studied. Several ratios were calculated using different parameters of the AC and the IH, including width, height and depth, the areas (axial and sagittal ellipse, as well as freehand sagittal surface areas) and these were compared with the reference methods of Sabbagh et al. and Tanaka et al. RESULTS: The LOD ratios calculated from the two reference methods gave similar results (ICC = 0.82, p < 0.0001). The new "R-ratios" (Reims-ratios) obtained from the IH and AC surface areas measured using the "freehand ROI" tool on sagittal view or roughly evaluated by an ellipse on axial view showed excellent correlation with both reference ratios (all ICC ≥ 0.71, p < 0.0001). CONCLUSION The LOD ratio may be quickly obtained by drawing two circles on the pre-operative CT scan ("R ratios") and available on the webpage https://romeo.univ-reims.fr/Rratio/ . This will certainly help surgeons to routinely anticipate the post-operative complications before IHLD repair.

Abstract
Abdominal wall (AW) hernias are a common problem faced by general surgeons. With an essentially clinical diagnosis, abdominal hernias have been considered a simple problem to be repaired. However, long-term follow-up of patients has shown disappointing results, both in terms of complications and recurrence. In this context, preoperative planning with control of comorbidities and full knowledge of the hernia and its anatomical relationships with the AW has gained increasing attention. Computed tomography (CT) appears to be the best option to determine the precise size and location of abdominal hernias, presence of rectus diastase and/or associated muscle atrophy, as well as the proportion of the hernia in relation to the AW itself. This information might help the surgeon to choose the best surgical technique (open vs MIS), positioning and fixation of the meshes, and eventual need for application of botulinum toxin, preoperative pneumoperitoneum or component separation techniques. Despite the relevance of the findings, they are rarely described in CT scans as radiologists are not used to report findings of the AW as well as to know what information is really needed. For these reasons, we gathered a group of surgeons and radiologists to establish which information about the AW is important in a CT. Finally, a structured report is proposed to facilitate the description of the findings and their interpretation.

Abstract
PURPOSE Patient optimization and selecting the proper technique to repair large incisional hernias is a multifaceted challenge. Body mass index (BMI) is a modifiable variable that may infer higher intra-abdominal pressures and, thus, predict the need for component separation (CS) at the time of surgery, but no data exist to support this. This paper assesses if the ratio of anterior-posterior (AP): transverse (TRSV) abdominal diameter, from pre-operative CT imaging, indicates a larger proportion of intra-abdominal fat and correlates with a hernia defect requiring a component separation for successful tension-free closure. METHODS Ninety patients were identified who underwent either an open hernia repair with mesh by primary closure (N = 53) or who required a component separation at the time of surgery (N = 37). Pre-operative CT images were used to measure hernia defect width, AP abdominal diameter, and TRSV abdominal diameter. Quantitative data, nominal data, and logistic regression was used to determine predictors associated with surgical group categorization. RESULTS The average hernia defect widths for primary closure and CS were 7.7 ± 3.6 cm (mean ± SD) and 9.8 ± 4.5, respectively (p = 0.015). The average BMI for primary closure was 33.9 ± 7.2 and 33.8 ± 4.9 for those requiring CS (p = 0.924). The AP:TRSV diameter ratios for primary closure and CS were 0.41 ± 0.08 and 0.49 ± 0.10, respectively (p < 0.001). In a multivariate analysis including both defect width and AP:TRSV diameter ratio, only AP:TRSV diameter ratio predicted the need for a CS (p = 0.001) while BMI did not (p = 0.92). CONCLUSION Intraabdominal fat distribution measured by AP:TRSV abdominal diameter ratio correlates with successful tension-free fascial closure during incisional hernia repair, while BMI does not.

Abstract
Computed tomography (CT) scanning is the imaging modality of choice when planning the overall management and operative approach to complex abdominal wall hernias. Despite its availability and well-recognised benefits there are no guidelines or recommendations regarding how best to read or report such scans for this application. In this paper we aim to outline an approach to interpreting preoperative CT scans in abdominal wall reconstruction (AWR). This approach breaks up the interpretive process into 4 steps-concentrating on the hernia or hernias, any complicating features of the hernia(s), the surrounding soft tissues and the abdominopelvic cavity as a whole-and was developed as a distillation of the authors' collective experience. We describe the key features that should be looked for at each of the four steps and the rationale for their inclusion.

Abstract
RESUMO Hérnias da parede abdominal são um problema bastante comum enfrentado pelo cirurgiões gerais. De diagnóstico essencialmente clínico, as hérnias abdominais durante muito tempo têm sido consideradas um problema de simples reparo. Entretanto, o acompanhamento de longo prazo dos pacientes têm demonstrado resultados desapontadores, tanto em termos de complicações quanto risco de recidiva da hérnia. Neste contexto, o planejamento pré-operatório com controle de comorbidades e pleno conhecimento da hérnia e suas relações anatômicas com a parede abdominal têm ganho cada vez mais atenção. A tomografia de abdome parece ser a melhor opção para determinar o tamanho e localização precisos das hérnias abdominais, presença de diastase de músculo reto e/ou atrofia da parede associada, assim como proporção da hérnia em relação a parede abdominal. Essas informações podem auxiliar o cirurgião na escolha da melhor técnica cirúrgica (aberta vs. MIS), posicionamento e fixação das telas, e eventual necessidade de aplicação de toxina botulínica, pneumoperitônio pré-operatório ou técnicas de separação de componentes. Apesar da relevância dos achados, eles são raramente descritos em exames de tomografia uma vez que os radiologistas não estão acostumados a olhar para a parede abdominal assim como não sabem quais as informações são realmente necessárias. Por estes motivos, nós reunimos um grupo de cirurgiões e radiologistas visando estabelecer quais são as informações da parede abdominal mais importantes em um exame de tomografia assim como propor um laudo estruturado para facilitar a descrição dos achados e sua interpretação.

Abstract
OBJECTIVES Systematic review of CT measurements to predict the success or failure of subsequent ventral hernia repair has found limited data available in the indexed literature. To rectify this, we investigated multiple preoperative CT metrics to identify if any were associated with postoperative reherniation. METHODS Following ethical permission, we identified patients who had undergone ventral hernia repair and had preoperative CT scanning available. Two radiologists made multiple measurements of the hernia and abdominal musculature from these scans, including loss of domain. Patients were divided subsequently into two groups, defined by hernia recurrence at 1-year subsequent to surgery. Hypothesis testing investigated any differences between CT measurements from each group. RESULTS One hundred eighty-eight patients (95 male) were identified, 34 (18%) whose hernia had recurred by 1-year. Only three of 34 CT measurements were significantly different when patients whose hernia had recurred were compared to those who had not; these significant findings were assumed contingent on multiple testing. In particular, preoperative hernia volume (recurrence 155.3 cc [IQR 355.65] vs. no recurrence 78.2 [IQR 303.52], p = 0.26) nor loss of domain, whether calculated using the Tanaka (recurrence 0.02 [0.04] vs. no recurrence 0.009 [0.04], p = 0.33) or Sabbagh (recurrence 0.019 [0.05] vs. no recurrence 0.009 [0.04], p = 0.25) methods, differed between significantly between groups. CONCLUSIONS Preoperative CT measurements of ventral hernia morphology, including loss of domain, appear unrelated to postoperative recurrence. It is likely that the importance of such measurements to predict recurrence is outweighed by other patient factors and surgical reconstruction technique. KEY POINTS • Preoperative CT scanning is often performed for ventral hernia but systematic review revealed little data regarding whether CT variables predict postoperative reherniation. • We found that the large majority of CT measurements, including loss of domain, did not differ significantly between patients whose hernia did and did not recur. • It is likely that the importance of CT measurements to predict recurrence is outweighed by other patient factors and surgical reconstruction technique.

Pre- and postsurgical imaging findings of abdominal wall hernias based on the European Hernia Society (EHS) classification. Abdom Radiol (NY) 2021; 46:5055-5071. [PMID: 34292364 DOI: 10.1007/s00261-021-03211-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 07/06/2021] [Accepted: 07/07/2021] [Indexed: 12/15/2022]
Abstract
Abdominal wall hernias are common and can present as technical challenges to surgeons. When large, hernias diminish quality of life. Various classifications of incisional hernias have been proposed; however, there are many terms, sometimes causing confusion (1). Radiologists must know the normal anatomy of the abdominal wall, the CT protocol, and what if any maneuvers can be performed to better identify an abdominal wall defect. The description of the radiological approach for primary and incisional wall hernias is based on the 2007 European Hernia Society classification, with particular emphasis on presurgical and postsurgical imaging findings. This classification provides a simple and reproducible method to describe hernias to offer proper surgical management. We highlight this classification so that radiologists and surgeons can have a unified language.

Abstract
PURPOSE Volumetric analysis is being increasingly utilized in the preoperative evaluation of complex incisional hernias. Three-dimensional (3D) reconstruction of abdominal computed tomography (CT) scan has been used to obtain surface area (SA) and volume (Vol.) measurements, while others have used simple mathematical formulas to obtain SA and Vol. estimates without 3D reconstruction. Our objective was to assess the correlation of SA and Vol. measurements and estimates of complex incisional hernias. METHODS We conducted a retrospective agreement study of adults who underwent abdominal wall reconstruction from 2007 to 2018. Demographics, hernia characteristics, and operative data were collected from the medical record. SA and Vol. measurements were obtained after 3D CT reconstruction. Linear CT variables were obtained independently by two surgeons and SA and Vol. estimates were calculated. Because both surgeons reported similar results, only lead author values are reported in the abstract. We used Pearson's correlation coefficient (r) to assess inter-rater agreement and the agreement between SA and Vol. measurements and estimates. RESULTS A total of 108 patients were eligible for analysis. The mean age was 57 ± 11 years and 53 (49%) were female. 42 (39%) hernias were recurrent, 10 (9%) patients had a stoma, and 9 (8%) had a history of open abdomen. The mean defect width was 11 ± 4 cm and mean defect surface area (DSA) was 150 ± 95 cm2. Inter-rater agreement of SA and Vol. estimates was high (r ≥ 0.80). There was high correlation between SA and Vol. measurements and estimates for DSA, hernia sac volume (HSV), abdominal cavity volume (ACV), and HSV/ACV ratio (r = 0.81, 0.89, 0.94 and 0.91, respectively). CONCLUSION SA and Vol. estimates demonstrated high level of agreement with SA and Vol. measurements using 3D reconstruction. SA and Vol. estimates can be obtained using simple mathematical formulas using easily obtained linear variables negating the need for the time and effort consuming 3D reconstruction.

Adjunct botox to preoperative progressive pneumoperitoneum for incisional hernia with loss of domain: no additional effect but may improve outcomes. Hernia 2021; 25:1507-1517.

Abstract
INTRODUCTION Incisional hernia with loss of domain (IHLD) remains a surgical challenge. Its management requires complex approaches including specific preoperative and intra-operative techniques. This study focuses on the interest of adding preoperative botulinum toxin A (BTA) injection to preoperative progressive pneumoperitoneum (PPP), compared to PPP alone. MATERIAL Patients between January 2015 and March 2020 with IHLD who underwent pre-operative preparation were included. Their baseline characteristics were retrospectively analyzed, along with the characteristics of their incisional hernia before and after preparation including CT-scan volumetry. Intra-operative data, early post-operative outcomes, surgical site occurrences (SSOs) including surgical site infection (SSI) were recorded. RESULTS Four hundred and fifty (450) patients with incisional hernia were operated, including 41 patients (9.1%) with IHLD, 13 of which had both BTA and PPP, while 28 had PPP only. Both groups were comparable in term of patients and IHLD characteristics. Median increase in the volume of the abdominal cavity (VAbC) was + 55% for the entire population (+ 58.3% for the BTA-PPP group, p < 0.0001 and + 52.8% for the PPP-alone group, p < 0.0001) although the increase in volume was not different between the two groups (p = 0.99). Complete fascial closure was achieved in all patients. SSOs were more frequent in the PPP-alone group than in the BTA-PPP group (17 (60.7%) versus 3 (23.1%) patients, respectively, p = 0.043). CONCLUSION BTA and PPP are both useful in pre-operative preparation for IHLD. Combining both significantly increases the volume of abdominal cavity but associating BTA to PPP does not add any volumetric benefit but may decrease the post-operative SSO rate.

Abstract
BACKGROUND Improved outcomes of abdominal wall reconstruction (AWR) have been shown when tension-free fascial closure (TFFC) is achieved. Our objective was to determine the clinical and radiologic predictors of TFFC in patients undergoing AWR. STUDY DESIGN We conducted a single institution retrospective cohort study of adults who underwent AWR between 2007 and 2018. Demographics, hernia characteristics and operative data were collected. Linear and volumetric variables were obtained from preoperative abdominal CT scans, the latter following 3D reconstruction. Logistic regression was used to evaluate predictors of TFFC. Area under the curve (AUC) ≥ 0.70 was considered to have acceptable discrimination. RESULTS A total of 108 patients were eligible for analysis. The mean age was 57 ± 11 years and 53 (49%) were female. 42 (39%) hernias were recurrent, 10 (9%) patients had a stoma and 9 (8%) had a history of open abdomen. The mean defect width was 11 ± 4 cm and mean defect surface area was 150 ± 95 cm2. The most common AWR technique was endoscopic component separation 75 (69%). TFFC was achieved in 90 (83%) patients. No demographics or 3D volumetric measures were predictive of TFFC (all AUC < 0.7). European hernia society (EHS) class M1 was predictive of failure of TFFC [AUC = 0.70; odds ratio 7.0 (referent M3); 95% confidence interval, 2.1-23.8]. Linear variables of rectus muscle separation were the most predictive of TFFC (AUC 0.73-0.77). CONCLUSION In contrast to clinical characteristics, radiologic characteristics of large incisional hernias requiring AWR are predictive of TFFC. In particular, EHS class M1 and linear variables of rectus muscle separation appear to be better predictors of TFFC than volumetric measurements.

Low-Dose Pre-Operative Botulinum Toxin A Effectively Facilitates Complex Ventral Hernia Repair: A Case Report and Review of the Literature. ACTA ACUST UNITED AC 2020; 57:medicina57010014. [PMID: 33379146 PMCID: PMC7824390 DOI: 10.3390/medicina57010014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 12/17/2020] [Accepted: 12/24/2020] [Indexed: 12/02/2022]
Abstract
Background: Complex ventral hernias following laparotomy present a unique challenge in that repair is hindered by the lateral tension of the abdominal wall. A novel approach to overcome this is the “chemical component separation” technique. Here, botulinum toxin A (BTA) is instilled into the muscles of the abdominal wall. This induces flaccid paralysis and effectively reduces tension in the wall, allowing the muscles to be successfully joined in the midline during surgery. We describe a method where a large incisional hernia was repaired using this technique and review the variations in methodology. Case report: A woman in her mid-40s developed a ventral hernia in the setting of a previous laparotomy for a small bowel perforation. Computed tomography (CT) of the abdomen demonstrated an 85 (Width) × 95 mm (Length) ventral hernia containing loops of the bowel. Pre-operative botulinum toxin A administration was arranged at the local interventional radiology department. A total of 100 units of BTA were instilled at four sites into the muscular layers of the abdominal wall under CT-fluoroscopic guidance. She underwent an open incisional hernia repair 4 weeks later, where the contents were reduced and the abdominal wall layers were successfully joined in the midline. There was no clinical evidence of hernia recurrence at 3-months follow-up. Conclusion: Low-dose BTA effectively facilitates the surgical management of large ventral incisional hernias. There is, however, significant variation in the dosage, concentration and anatomical landmarks in which BTA is administered as described in the literature. Further studies are needed to assess and optimise these variables.

Abstract
Ventral hernias are a complex and costly burden to the health care system. Although preoperative radiologic imaging is commonly performed, the plethora of anatomic features present and available in routine imaging are seldomly quantified and integrated into patient selection, preoperative risk stratification, and perioperative planning. We herein aimed to critically examine the current state of computed tomography feature application in predicting surgical outcomes. Methods A systematic review was conducted in accordance with the Preferred Reporting Items for a Systematic Review and Meta-Analysis (PRISMA) checklist. PubMed, MEDLINE, and Embase databases were reviewed under search syntax "computed tomography imaging" and "abdominal hernia" for papers published between 2000 and 2020. Results Of the initial 1922 studies, 12 papers met inclusion and exclusion criteria. The most frequently used radiologic features were hernia volume (n = 9), subcutaneous fat volume (n = 5), and defect size (n = 8). Outcomes included both complications and need for surgical intervention. Median area under the curve (AUC) and odds ratio were 0.68 (±0.16) and 1.12 (±0.39), respectively. The best predictive feature was hernia neck ratio > 2.5 (AUC 0.903). Conclusions Computed tomography feature selection offers hernia surgeons an opportunity to identify, quantify, and integrate routinely available morphologic tissue features into preoperative decision-making. Despite being in its early stages, future surgeons and researchers will soon be able to integrate 3D volumetric analysis and complex machine learning and neural network models to improvement patient care.

Prehabilitation of complex ventral hernia patients with Botulinum: a systematic review of the quantifiable effects of Botulinum. Hernia 2020; 25:1427-1442.

Abstract
PURPOSE Complex ventral hernia repair (CVHR) encompasses patient optimization, primary fascial closure (PFC), mesh reinforcement and component separation technique (CST), if needed. High rates of complications after CST are still reported. Prehabilitation by managing pre-operative modifiable risk factors, like abdominal wall compliance, possibly reduces these rates. Compliance can be modified by intramuscular injection of Botulinum in the lateral abdominal wall muscles (LAWM). Paralysis leads to elongation of these muscles, which may facilitate PFC and/or prevent CST. Evidence to use Botulinum in hernia patients is scarce and fragmented. An update of evidence for the effect of Botulinum is presented. METHODS A multi-database search was conducted for Botulinum studies in ventral hernia patients. A systematic review was performed to describe its primary effect on compliance (LAWM elongation) and secondary effects like PFC ± CST rate, complications and recurrence. RESULTS 14 studies were included (377 patients) with a HDW of median 12 (10-15) cm. A typical intervention consisted of 200-300 U Botulinum in 3 points per hemi-abdomen under US guidance, > 2 weeks pre-operatively and evaluated by CT just before the operation. The primary effect was a median LAWM elongation of 4.0 cm per side without complications of the injection (four studies, 107 patients). The median PFC rate was 100%, CST rate 38%, wound-related complications 19%, medical complications 18% and recurrence 0% (14 studies). CONCLUSION Botulinum safely elongates the abdominal wall muscles, but the level of evidence available remains low. Any patient in whom PFC is expected to be difficult, could be a candidate for prehabilitation with Botulinum.

Abstract
BACKGROUND Weight loss is often encouraged or required before open ventral hernia repair. This study evaluates the impact of weight change on total, intra-abdominal, subcutaneous, and hernia volume. METHODS Patients who underwent open ventral hernia repair from 2007 to 2018 with two preoperative computed tomography scans were identified. Scans were reviewed using 3D volumetric software. Demographics, operative characteristics, and outcomes were evaluated. The impact of weight change on intra-abdominal, subcutaneous, and hernia volume was assessed using Spearman's correlation coefficients and linear regression models. RESULTS A total of 250 patients met the criteria with a mean defect area of 155.6 ± 155.4 cm2, subcutaneous volume of 6,800.0 ± 3,868.8 cm3, hernia volume of 915.7 ± 1,234.5 cm3, intra-abdominal volume equaling 4,250.2 ± 2,118.1 cm3, and time between computed tomography scans 13.9 ± 11.0 months. Weight change was associated with change in hernia, intra-abdominal, total, and subcutaneous volume (Spearman's correlation coefficients 0.17, 0.48, 0.51, 0.45, respectively, P ≤ 0.03 all values) and not associated in hernia length, width, or area (P ≥ 0.18 all values). A Δ5 kg was significantly associated with Δintra-abdominal volume (164.1 ± 30.0 cm3/Δ5 kg,P < .0001), Δtotal volume (209.9 ± 33.0 cm3/Δ5 kg, P < .0001), and Δsubcutaneous volume (234.4 ± 50.8 cm3/Δ5 kg, P < .0001). Per Δ5 kg, male patients had more than double the Δintra-abdominal, Δtotal, and Δsubcutaneous volume than did female patients. A weight change of 5 kg to10 kg was associated with approximately double the change in computed tomography parameters/Δ5 kg than any weight change after 10 kg. Regardless of weight change, all measured hernia parameters increased over time, with mean hernia volume of +40.6 ± 94.9 cm3/mo and area of +7.8 ± 13.3 cm2/mo (Spearman's correlation coefficient -0.03 to 0.07, P value 0.37-0.96). CONCLUSION Weight change is linearly correlated with intra-abdominal and subcutaneous fat gain or loss. Males show greater abdominal-related response to weight gain or loss. Hernia dimensions increase over time regardless of weight change.

Abstract
BACKGROUND Component separation technique (CST) allows fascial medialization during abdominal wall reconstruction (AWR). Wound contamination increases the incidence of wound complications, which multiplies the incidence of repair failure. The aim of this study was to compare the impact of CST on AWR outcomes in contaminated fields in comparison to those operations without CST. METHODS A prospective, single institution hernia database was queried for patients undergoing AWR with CST and contamination. A case control cohort was identified using propensity score matching. RESULTS There were 286 CSTs performed in contaminated cases. After propensity score matching, 61 CSTs were compared to 61 No-CSTs. These groups were matched by defect area (CST:287.1 ± 150.4 vs No-CST:277.6 ± 218.4 cm2, p = 0.156), BMI (32.0 ± 7.0 vs 32.2 ± 6.0 kg/m2, p = 0.767), diabetes (26.2% vs 32.8%, p = 0.427), and panniculectomy (52.5% vs 36.1%, p = 0.068). Groups had similar rates of wound complications (42.6% vs 40.7%, p = 0.829) and recurrence (4.9% vs 13.1%, p = 0.114). CONCLUSIONS The use of CST in the face of contamination is not associated with an increase in wound complications, mesh complications, or recurrence.

Pooled data analysis of primary ventral (PVH) and incisional hernia (IH) repair is no more acceptable: results of a systematic review and metanalysis of current literature. Hernia 2019; 23:831-845. [PMID: 31549324 DOI: 10.1007/s10029-019-02033-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Accepted: 08/07/2019] [Indexed: 01/20/2023]
Abstract
PURPOSE Primary (PVHs) and incisional (IHs) ventral hernias represent a common indication for surgery. Nevertheless, most of the papers presented in literature analyze both types of defect together, thus potentially introducing a bias in the results of interpretation. The purpose of this systematic review and meta-analysis is to highlight the differences between these two entities. METHODS Methods MEDLINE, Scopus, and Web of Science databases were reviewed to identify studies evaluating the outcomes of both open and laparoscopic repair with mesh of PVHs vs IHs. Search was restricted to English language literature. Risk of bias was assessed with MINORS score. Primary outcome was recurrence, and secondary outcomes were baseline characteristics and intraoperative and postoperative data. Fixed effects model was used unless significant heterogeneity, assessed with the Higgins I square (I2), was encountered. RESULTS The search resulted in 783 hits, after screening; 11 retrospective trials were selected including 38,727 patients. Mean MINORS of included trials was 15.2 (range 5-21). The estimated pooled proportion difference for recurrence was - 0.09 (- 0.11; - 0.07) between the two groups in favor of the PVH group. On metanalysis, PVHs were smaller in area and diameters, affected younger and less comorbid patients, and were more frequently singular; the operative time and length of stay was quicker. Other complications did not differ significantly. CONCLUSION Our paper supports the hypothesis that PVH and IH are different conditions with the latter being more challenging to treat. Accordingly, EHS classifications should be adopted systematically as well as pooling data analysis should be no longer performed in clinical trials.

Abstract
INTRODUCTION BMI and hernia defect size are strongly associated with outcomes after open ventral hernia repair (OVHR). The impact of abdominal subcutaneous fat (SQV), intra-abdominal volume (IAV), hernia volume (HV), and ratio of HV to intra-abdominal volume (HV:IAV, representing visceral eventration) is less clearly elucidated. This study examines the interaction of multiple markers of adiposity and hernia size in OVHR. METHODS OVHR with preoperative CT scans were identified. 3D volumetric software measured HV, SQV, IAV, and HV:IAV was calculated. A principal component analysis was performed to create new component variables for collinear variables. Hernia PC was composed primarily of hernia dimensions, EAV (extra-abdominal volume PC) included SQV and BMI, and IAV PC included IAV. RESULTS A total of 1178 OVHR patients had a preoperative CT scan. Their demographics included a mean age of 58.5 ± 12.4 years, BMI of 34.2 ± 7.7 kg/m2, and 57.8% were female. The mean defect area was 150.8 ± 136.7 cm2, and 66.0% were recurrent, Patients had mean SQV of 6719.4 ± 3563.9 cm3, HV of 966.9 ± 1303.5 cm3, IAV of 4250.2 ± 2118.1 cm3, and a HV:IAV of 0.29 ± 0.46. In multivariate analysis, Hernia PC was associated with panniculectomy (OR 1.52, CI 1.37-1.69) and component separation (OR 1.34, CI 1.21-1.49) and was negatively associated with fascial closure (OR 0.78, CI 0.69-0.88). Hernia PC was also associated with reoperation, readmission, and development of wound complications (OR 1.18, CI 1.08-1.30; OR 1.15, CI 1.04-1.27; OR 1.28, CI 1.16-1.41, respectively). EAV PC was associated with performance of a panniculectomy (OR 1.33, CI 1.20-1.48), readmission (OR 1.18, CI 1.06-1.32), and wound complications (OR 1.41, CI 1.27-1.57). IAV PC was not associated with adverse outcomes. CONCLUSION Values of hernia area, volume, IAV, HV:IAV, BMI, and SQV are collinear markers of patient obesity and hernia proportions. They are distinct enough to be represented by three principal component variables, indicating more nuanced discrete influences on variability of surgical outcomes other than BMI.

Abstract
Background. Incisional hernias (IHs) can develop in up to 15% of patients who underwent an abdominal surgical procedure. Abdominal computed tomography (CT) is the best examination to evaluate these patients before surgical repair. The aim of this study is to assess the usefulness of the abdominal CT scan during Valsalva’s maneuver in patients who are candidates for surgery. Methods. A retrospective cohort analysis conducted on prospectively recorded data was performed on 26 consecutive patients affected by IHs who underwent a preoperative abdominal CT scan both at rest and during Valsalva’s maneuver between January 1, 2015, and December 31, 2016. Results. Five patients (19%) had IH classified as M1-M2, 10 (39%) as M3, and 11 (42%) as M4-M5. Both the median IH orifice area (IHOA) and the median volume of the IH increased during straining ( P = .001 and P < .001, respectively). The percentage of the difference in volume ratios increased as the localization of the IH moved caudally. At the binary logistic regression analysis M3 IH, body mass index >28, IHOA > 156 cm2 at rest, and IHOA > 138 cm2 during Valsalva’s maneuver were risk factors for posterior component separation. Conclusions. The preoperative CT scan both at rest and during Valsalva’s maneuver seemed useful to estimate the risk of difficult IH repairs. Moreover, it could allow surgeons to decide if the patient should be addressed to more specialized centers.

Abstract
Abdominal wall hernia repair is one of the most common operations done by general surgeons today. Patients with incisional hernias can be extremely challenging to manage due to a number of factors that include obesity, prior hernia repairs, previous mesh placement, loss of domain, and other variables. The approach to patients with incisional hernias has evolved considerably over the last 20 years due to both advances in mesh technology and surgical approaches. Key factors in a successful outcome include modification of risk factors prior to surgery such as smoking cessation and weight reduction, selection of mesh appropriate to the hernia type and planned location of the mesh, and broad overlap of mesh beyond the margins of the hernia defect. Newer techniques such as transabdominis release and component separation with retrorectus mesh placement and robotic approaches to abdominal wall hernia are being increasingly utilized in these patients. This article reviews these aspects of abdominal wall hernia repair with a discussion of recent results and the importance of quality improvement and monitoring of outcomes.

Abstract
Bullhorn injury is a rare mechanism causing traumatic abdominal wall hernia (TAWH). Bullhorn injury needs to be discussed as a separate sub-entity among TAWHs as the mechanism of injury is such that the great force is generated at a relatively small area of impact for a short duration of time which may lead to muscle defect without compromising integrity of overlying skin (referred to as sheathed goring) leading to herniation of abdominal viscera. The purpose of this review was to discuss abdominal herniation's associated with bullhorn injury as a separate entity from TAWHs; recognize the common presentations, mechanism of injury, and modalities of treatment currently utilized for this rare condition. A comprehensive online English, Spanish, Portuguese, and French language medical literature search was done using various electronic search databases. Different search terms including MeSH related to bullhorn-injury associated injuries including abdominal wall hernias were used. An advanced search was further conducted by combining all the search fields in abstracts, keywords, and titles. We summarized the data from the searched articles and found 12 cases who underwent emergency or elective herniorrhaphy with or without the use of mesh. We have proposed a treatment algorithm for such cases in light of the present era of laparoscopy and propose the usage of the term “bullhorn-injury associated traumatic hernia” for such cases. We present here the first most comprehensive discussion of all such cases reported till date.

Abstract
Abstract Complex ventral hernia (CVH) describes large, anterior, ventral hernias. The incidence of CVH is rising rapidly due to increasing laparotomy rates in ever older, obese and co-morbid patients. Surgeons with a specific interest in CVH repair are now frequently referring these patients for imaging, normally computed tomography scanning. This review describes what information is required from preoperative imaging and the surgical options and techniques used for CVH repair, so that radiologists understand the postoperative appearances specific to CVH and are aware of the common complications following surgery. Key Points • Complex ventral hernia (CVH) describes large abdominal wall hernias (e.g. width ≥10cm). • CVH patients are being referred increasingly for preoperative and postoperative imaging. • Imaging is pivotal to characterise preoperative morphology and quantify loss of domain. • Postoperative imaging appearances are contingent on the surgical methods used for CVH repair. • Postoperative complications are depicted easily by imaging.
