Ventral Hernia Repair Research Articles

Concurrent minimally invasive bariatric surgery and ventral hernia repair with mesh; Is it safe? Propensity score matching analysis using the 2015-2022 MBSAQIP database.

Obesity is a risk factor for the development of ventral hernias. Approximately eight percent of patients undergoing bariatric surgery have a concomitant ventral hernia. However, the optimal timing of hernia repair in these patients is debated. Concerns regarding mesh insertion in a potentially contaminated field are often cited by opponents of a combined approach. Our study compares 30-day outcomes of bariatric surgery with concurrent ventral hernia repair with mesh versus bariatric surgery alone. Using the 2015-2022 MBSAQIP database, patients aged 18-65years who underwent minimally invasive sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) with or without concurrent ventral hernia repair with mesh (VHR-M) were identified. 30-day postoperative outcomes were compared between patients who underwent SG or RYGB with VHR-M versus SG or RYGB alone. 1:1 propensity score matching was performed using 26 preoperative characteristics to adjust confounders. Among 1,236,644 patients who underwent SG (n = 871,326) or RYGB (n = 365,318), 3,121 underwent SG + VHR-M and 2,321 RYGB + VHR-M. The concurrent approach had longer operative times, in SG + VHR-M (86.06 ± 42.78 vs. 73.80 ± 38.45min, p < 0.001), and in RYGB + VHR-M (141.91 ± 58.68 vs. 128.47 ± 62.37min, p < 0.001). The RYGB + VHR-M cohort had higher rates of reoperations (3.2% vs. 2.1%, p = 0.024). Overall, 30-day outcomes, and bariatric-specific complications such as mortality, unplanned ICU admissions, surgical site complications, cardiac, pulmonary, renal complications, anastomotic leaks, postoperative bleeding, and intestinal obstruction were similar between SG + VHR-M or RYGB + VHR-M groups versus SG or RYGB alone. Bariatric surgery performed concurrently with VHR-M is safe and feasible and does not excessively prolong operative times. However, patients undergoing RYGB with VHR-M do have a higher rate of reoperations, therefore a staged VHR is recommended. On the other hand, concurrent SG and VHR-M may benefit after an appropriate individualized risk stratification assessment.

Comparison of eTEP and IPOM for ventral hernia surgery in the early postoperative period: a retrospective cohort study of a tertiary university centre.

The extended totally extraperitoneal technique (eTEP) is a relatively new laparoscopic approach to address ventral hernias. Since this technique is not widely used yet, the literature regarding its efficacy and safety is limited, especially when compared to more established surgical techniques like intraperitoneal onlay mesh (IPOM). This study aimed at contributing to the expanding body of evidence for eTEP, by comparing the early outcomes of eTEP and IPOM surgeries for ventral hernias. This monocentric, retrospective cohort study compared patients with ventral hernias that were treated with eTEP or IPOM from 2019 to 2023. A total of 123 patients were analysed. 92 underwent eTEP and 31 IPOM respectively. Both groups were overall comparable. The IPOM group had a higher proportion of incisional hernias (61,29% vs. 21,74%, p < 0,001). This was taken into account for in a subgroup analysis of only primary hernias. The IPOM group had a significantly longer admission time (eTEP: 3 days, IPOM: 4 days, p < 0,001). The subgroup analysis revealed a statistically significant shorter surgery time in IPOM (median of 66,5min vs. 106,5min; p = 0,043) and a lower rate of postoperative complications in eTEP (eTEP: 4,17%, IPOM: 25%. p = 0,009). The eTEP group reported lower postoperative pain, yet without statistical significance. eTEP for ventral hernia repair appears to be non-inferior to IPOM. Compared to IPOM it leads to shorter postoperative hospital stay and a potentially lower complication rate, despite a longer operation time.

Open versus robotic retromuscular ventral hernia repair: outcomes of the ORREO prospective randomized controlled trial.

Robotic retromuscular ventral hernia repair (rRMVHR) potentially combines the best features of open and minimally invasive VHR: myofascial release with abdominal wall reconstruction (AWR) with the lower wound morbidity of laparoscopic VHR. Proliferation of this technique has outpaced the data supporting this claim. We report 2-year outcomes of the first randomized controlled trial of oRMVHR vs rRMVHR. Single-center randomized control trial of open vs rRMVHR. 100 patients were randomized (50 open, 50 robotic). We included patients > 18 y/o with hernias 7-15cm with at least one of the following: diabetes, chronic obstructive pulmonary disease (COPD), body mass index (BMI) ≥ 30, or current smokers. Primary outcome was occurrence of a composite outcome of surgical site infection (SSI), non-seroma surgical site occurrence (SSO), readmission, or hernia recurrence. Secondary outcomes were length of stay, any SSI or SSO, SSI/SSOPI, operative time, patient reported quality of life, and cost. Analysis was performed in an intention-to-treat fashion. Study was funded by a grant from Society of American Gastrointestinal and Endoscopic Surgeons. 90 patients were available for 30-day and 62 for 2-year analysis (rRMVHR = 46 and 32, oRMVHR = 44 and 30). Hernias in the open group were slightly larger (10 vs 8cm, p = 0.024) and more likely to have prior mesh (36.4 vs 15.2%; p = 0.030), but were similar in length, prior hernia repairs, mesh use, and myofascial release. There was no difference in primary composite outcome between oRMVHR and rRMVHR (20.5 vs 19.6%, p = 1.000). Median length of stay was shorter for rRMVHR (1 vs 2days; p < 0.001). All patients had significant improvement in quality of life at 1 and 2years. Other secondary outcomes were similar. There is no difference in a composite outcome including SSI, SSOPI, readmission, and hernia recurrence between open and robotic RMVHR.

SP1.2 - Laparoscopic versus Robotic ventral hernia repair: a systematic review and meta-analysis comparing the perioperative outcomes randomised controlled trials

Abstract Objective The objective of this meta-analysis is to compare the perioperative surgical outcomes and cost-effectiveness of robotic incisional/ventral hernia repair (RIVHR) versus laparoscopic incisional/ventral hernia repair (LIVHR). Methods Randomised control trials (RCTs) reporting perioperative outcomes and costs in patients undergoing RIVHR versus LIVHR were selected from medical electronic databases and meta-analysis was conducted under the guidelines of the Cochrane Collaboration using statistical software RevMan version 5. Results Four RCTs on 337 patients reporting perioperative outcomes and cost comparison were included. In the random effect model analysis, the duration of operation [standardized mean difference (SMD) -48.07, 95%, CI (-78.06, -18.07), z = 3.14, p = 0.002] was shorter and cost was lower [SMD 0.82, 95%, CI (-1.48, -0.16), z = 2.45, p = 0.01] in the LIVHR group but with significant statistical heterogeneity. However, the variables of hernia recurrence [risk ratio (RR) 2.29, 95%, CI (0.73, 7.12), z = 1.43, p = 0.15] and surgical site complications [RR 0.85, 95%, CI (0.48, 1.50), z = 0.55, p = 0.58] were statistically similar in both groups without any statistical heterogeneity among the included studies. Conclusion The RIVHR does not offer any superiority over LIVHR in all perioperative variables and it is not cost effective. Due to the paucity of the RCTs, a major multi-centre RCT is needed to validate these findings.

Elective complex ventral hernia repair in contaminated fields: A propensity score–matched analysis of long-term quality of life and outcomes between different prostheses

BackgroundRandomized studies have endorsed nonabsorbable prosthetics for contaminated ventral hernia surgery, yet the broader applicability and impact on patient-reported outcomes are still questioned. Here, we evaluated the long-term outcomes of elective contaminated ventral hernia repairs (based on Centers of Disease Control and Prevention [CDC] wound classification) using real-world data from a multicenter US cohort, focusing on quality of life and postoperative pain. MethodsThe Abdominal Core Health Quality Collaborative database was queried for patients undergoing elective contaminated (CDC class II–IV) ventral hernia repair (2013–2023). After propensity matching, we compared long-term differences in patient-reported quality of life and pain scores (by HerQLes and PROMIS questionnaires) among those who underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh. ResultsA total of 1,073 patients were included, of whom 920 (86%), 56 (5%), and 97 (9%) underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh, respectively. Among them, the median age was 62 years (interquartile range [IQR] 53–70), and 523 (49%) were male. The median length and width of the defect were 20 cm (IQR 12–25) and 13 cm (IQR 8–16), respectively. A transversus abdominis release was performed in 716 patients (67% of all cases). In most cases, the mesh was positioned in the retro-rectus (85%) and/or the preperitoneal space (45%). Before and after propensity matching (n = 185), the change from baseline in HerQLes and PROMIS scores at 6 months and at 1, 3, 5, and 6 years was comparable between different types of mesh. Lastly, there were no differences in readmission, surgical site infection, or surgical site occurrence at 30 days. Recurrence at 1 year was also comparable among groups. ConclusionIn the long term, there were no differences in quality of life or pain scores with nonabsorbable, absorbable synthetic, or biologic mesh for elective ventral hernia repair in contaminated fields.

The outcomes of component separation technique versus no component separation technique in the repair of large ventral hernias and impact on quality of life: a multicenter retrospective cohort study.

This study aimed to compare the results of patients who underwent anterior component separation techniques (ACST) and those who did not undergo component separation techniques (non-CST) in complicated ventral hernia repairs (VHRs) and to investigate the effect of these techniques on quality of life (QoL). A total of 105 patients who were operated for large ventral hernias were retrospectively analyzed. The patients were divided into the ACST group (n = 48) and the non-CST group (n = 57). Demographic, intraoperative, and postoperative data were recorded. Postoperative follow-up was conducted at 2 and 4 weeks, and 6, 12, and 24 months. The primary and secondary outcomes and QoL were measured. The female ratio was higher in both groups (P = 0.512). There was no significant difference between age and body mass index between the groups (P = 0.705 and P = 0.803). The mean defect size and mesh size were similar between the groups (P = 0.775 and P = 0.245). The mean operation duration and amount of blood loss were similar between the groups (P = 0.801 and P = 0.142). There was no statistically significant difference in the median visual analog scale scores between the groups (P = 0.551). During follow-up, only 3 patients (6.3%) in the ACST group and 4 patients (7.0%) in the non-CST group had recurrence. There was no significant difference in the short- and long-term QoL between the groups. The ACST is a feasible surgical option for patients with complicated VHRs. In addition, by improving QoL, the recurrence rate is similar to patients undergoing standard VHR.

Long-term outcomes of open midline ventral hernia repair using a narrow well-fixed retrorectus polypropylene mesh.

The ultimate measure of successful abdominal wall reconstruction is a pain-free, complication-free, and durable hernia repair. Open techniques have generally lost favor, but they still have much to offer for patients with skin deficits and excess. The long-term complication rates for open hernia repairs is unknown. Electronic medical records now provide the ability to easily follow patients who have switched medical institutions. Using this tool, we followed a cohort of abdominal wall reconstruction patients who had an early high "success" rate. We performed a retrospective chart review of 101 patients who underwent open ventral hernia repair with a narrow well-fixed retrorectus uncoated polypropylene mesh by a single surgeon (GAD) between the years of 2010 and 2015. These patients were initially reported in a 2016 publication. Patients' post-operative follow-up by any medical provider assessing the abdominal region were studied up until August 2023. Patient demographics, operative reports, and postoperative course were re-reviewed. A total of 101 patients underwent ventral hernia repair. Mean follow-up time was 7.68years (range 1.8 - 13.0years). There were no recurrent hernias across the studied time period and no instances of enterocutaneous fistulas. 15 patients (15%) had abdominal surgery after hernia repair unrelated to their original surgery and 5 patients (5%) reported chronic post-operative pain. 13 patients died in the follow-up period, all unrelated to the abdominal wall surgery. Open well-fixed narrow retrorectus mesh hernia repairs perform well in the long-term without fistulas, extrusions, and hernia recurrence.

Intraperitoneal Onlay Mesh Repair (IPOM) versus Intraperitoneal Onlay Mesh Repair with Closure of Fascia Defect (IPOM Plus) for Ventral Hernias: Retrospective Analysis of Postoperative Outcomes

Background: Intra-peritoneal onlay mesh (IPOM) repair, a type of Laparoscopic Ventral Hernia Repair (LVHR), comprises bridging the defect from the peritoneal side with a composite mesh. Recently, IPOMPlus has become the recommended type of LVHR in which the defect in the fascia is sutured before placing the mesh. Materials and Methods: This study is a retrospective cohort study conducted at Dharan Hospital, Salem. Patients who had undergone IPOM-Plus or IPOM during January 2020 to June 2021 were selected. Data regarding demographics, intra-operative and post-operative outcomes were collected from medical record section. Patients were followed up for 6 months. Data analysis was performed using SPSS version 26.0 taking a p-value of &lt;0.05 as statistically significant. Results: A total of 74 patients were included in this study, out of which 34 patients had undergone IPOM (Group A) and 40 patients underwent IPOM-Plus (Group B). In both the groups, there was no statistical difference in demographic variables except more number of umbilical hernia in both the groups compared to epigastric and paraumbilical hernia. Hernia defect size and mean operative time were varied significantly (p-value &lt; 0.05) in both groups. More number of seroma formation (p=0.021), pseudosac at first OPD visit (p=0.020) and pseudosac at 6 months (p=0.027) in Group A compared to Group B. Conclusions: IPOM plus repair is safe with possible advantages over a standard IPOM repair in patients with ventral hernia in term of postoperative outcomes.

Robotic Ventral Hernia Repair: Indications and Outcomes

Robotic Ventral Hernia Repair: Indications and Outcomes

Community Privilege and Unplanned Surgery for Access-Sensitive Surgical Conditions.

We sought to define the association of privilege on rates of unplanned surgery and perioperative outcomes for access-sensitive surgical conditions. Social determinants of health (SDOH) are critical in influencing timely access to healthcare. Privilege represents a right, benefit, advantage, or opportunity that positively influences all SDOH. The California Department of Health Care Access and Information (HCAI) database identified patients who underwent abdominal aortic aneurysm repair, ventral hernia repair, or colectomy for colon cancer between 2017 and 2020 and was merged using ZIP codes with the Index of Concentration of Extremes, a validated measure of racial and economic privilege obtained from the American Community Survey. Clustered multivariable regression was performed to assess the association between privilege and outcomes. Among 185,316 patients who underwent a surgical procedure for one of three access-sensitive surgical conditions, roughly 1 in 5 individuals resided in areas with the highest (Q5; n=37,308; 20.1%) or lowest (Q1; n=36,352, 19.6%) privilege. Nearly one-half of the surgeries were unplanned (n=88,814, 46.9%), and colectomy for colon cancer was the most performed emergent procedure. Patients residing in the lowest privileged areas had higher rates of unplanned surgery compared with those residing in the highest privilege (Q1; 55.4% vs. 39.4%; referent: Q5; adjusted odds ratio [OR], 1.23, 95%CI 1.16-1.31; P<0.001). For each access-sensitive surgical condition, patients in the least privileged areas were more likely to experience higher rates of inpatient mortality (Q1; 3.1% vs. 2.1%; referent: Q5; adjusted OR, 1.41, 95%CI 1.24-1.60; P<0.001), perioperative complications (Q1; 30.4% vs. Q5; 23.8%; referent: Q5; adjusted OR, 1.24, 95%CI 1.18-1.31; P<0.001) and extended hospital stays (Q1; 26.3% vs. 20.1%; referent: Q5; adjusted OR, 1.16, 95%CI 1.09-1.22; P<0.001). Privilege was associated with rates of unplanned surgery and adverse clinical outcomes. This indicates the role privilege as a key SDOH that influences patient access to and quality of surgical care.

Robotic-assisted surgery for lateral ventral hernias - experience of robot-assisted methods for retromuscular and preperitoneal abdominal wall reconstruction.

Due to the proximity to bony structures and the complex anatomy of the three-layered lateral abdominal wall, the surgical treatment of lateral ventral hernias is technically demanding. With this study we would like to demonstrate how lateral abdominal wall hernias can be treated using new robotic surgical techniques with extraperitoneal mesh placement. The purpose of this study is to demonstrate that the application of the robot in minimally invasive treatment of lateral abdominal wall hernias is safe and efficient. A retrospective analysis of all patients who underwent robotically-assisted lateral ventral hernia repair surgery from June 2019 to December 2023 was performed. A total of 50 ventral hernias were operated robotically due to a lateral hernia in the study period. 45 patients had an incisional hernia and 5 patients a primary spighelian hernia. 27 patients had only lateral findings, whereas 23 patients had combined hernias with lateral and medial hernial defects. 18 patients were treated with a preperitoneal mesh (r-vTAPP). 31 patients required TAR to achieve complete fascial closure and sufficient mesh overlap (24 extraperitoneal approach r-eTAR/7 transperitonel approach r-TAR). One patient had to be converted intraoperatively from a planned preperitoneal mesh to an intraperitoneal mesh repair (r-IPOM). The median hernia defect area was 71cm² (3-375cm²). The median mesh size was 600cm² (150-1290cm²). The median mesh defect ratio (MDR) was 10 (2,33-133,33). Five postoperative complications were encountered (10%). Two reoperations (4%) were required. The utilization of new robotic surgical techniques provides a safe minimally invasive treatment option even for complex lateral ventral hernias that previously posed difficulties in surgical management. The early postoperative results show promising outcomes.

Association of changes in HerQLes scores with objective hernia outcomes: an analysis of the ACHQC database.

There are both objective and subjective measures of success following ventral hernia repair (VHR). Using the Abdominal Core Health Quality Collaborative (ACHQC) database, we sought to determine if there is an association between 30-day wound events (objective) and changes in the hernia-related quality-of-life (HerQLes) scores, (subjective). We hypothesized that patients who do not experience a 30-day wound event have a greater improvement in their HerQLes score over the short-term. All adult patients who underwent VHR with 30-day follow-up data available between 2013 and 2022 were identified within the ACHQC database. The 30-day wound events included surgical site infection (SSI), surgical site occurrence (SSO), and SSO requiring procedural intervention (SSOPI). The association between 30-day wound events and changes in HerQLes scores was measured using propensity matched score analysis. Further, regression analysis was used to determine if an improvement in HerQLes score at 30-days postoperatively was associated with the likelihood of experiencing a 30-day wound event. Following a 3:1 matched analysis, 17,796 patients were available for analysis; 4449 (25%) patients experienced a 30-day wound event. The most common SSI was a superficial SSI and the most common SSO was a seroma. A 10-point improvement in the HerQLes score was statistically associated with a 3% decrease in SSI and a 4% decrease in the odds of experiencing an SSO. While not statistically significant, a 10-point improvement in the HerQLes score was associated with a 2.4% decrease in the odds of experiencing an SSOPI. Subjective and objective measures of success following VHR seem to be correlated with one another over the short-term. Additional studies are needed to determine if this correlation exists with other subjective and objective measures of success and to determine if these correlations persist over the long-term. If present, these associations may help to guide patient counseling as experiencing a postoperative wound event following ventral hernia repair may not be detrimental to their quality-of-life over the long-term.

Open suture repair versus PermacolTM mesh repair of small ventral hernias in patients with end-stage kidney disease.

Ventral hernia is a common surgical problem among patients with end-stage kidney disease (ESKD), while the optimal repair technique for small ventral hernias is controversial. This study aimed to compare the outcomes of open suture repair versus biological mesh repair of small ventral hernias with defect size ≤2 cm in ESKD patients. Data from consecutive ESKD patients who underwent elective ventral hernia repair with defect size ≤2 cm at a single institution from January 2012 to January 2022 were retrospectively reviewed. Outcomes of open suture repair were compared to PermacolTM mesh repair. The primary outcome was recurrence rate. Secondary outcomes included post-operative complications, peri-operative and post-operative dialysis regimen. Forty-seven ventral hernia repairs were included, with 20 being suture repairs and 27 being PermacolTM mesh repairs. Median age at hernia repair was 60 (range 32-81) years old. Pre-operatively, 42 patients (89.4%) were on peritoneal dialysis (PD). Paraumbilical hernia (59.6%) was most common. Median hernia defect size was 15 mm (range 2-20 mm). Upon median follow-up of 56 (range 9-119) months, more patients in the suture repair group developed recurrence (30% vs. 0%, p = 0.004). Median time to recurrence was 10 (range 5-16) months. There was no wound or mesh infection. The majority of patients underwent intermittent PD peri-operatively and were able to resume on PD in the long run. Ventral hernia repair is indicated in ESKD patients even for small defects; repair with PermacolTM mesh was associated with a lower recurrence rate when compared to suture repair and post-operative morbidity was low.

Defect width and operative time are the most significant predictors of venous thromboembolism in ventral hernia repair

BackgroundVenous thromboembolism is a significant cause of morbidity and mortality among patients undergoing ventral hernia repair. Several risk-assessment models have been developed to predict venous thromboembolism risk for various surgical procedures. However, these models do not include hernia-specific risk factors. Therefore, we sought to evaluate the predictors of venous thromboembolism in patients with a ventral hernia repair in a national hernia-specific database. MethodsThe Abdominal Core Health Quality Collaborative database was retrospectively queried for ventral hernia repair data. The ventral hernia repair procedures were divided into 2 groups on the basis of whether the patients developed perioperative venous thromboembolism. Baseline and operative characteristics and perioperative outcomes were compared between the 2 groups. The logistic regression was used to assess the association between different risk factors and venous thromboembolism. ResultsA total of 43,558 patients were included in the study. The 30-day venous thromboembolism rate among these patients was 0.62% (n = 269). Venous thromboembolism was associated with greater 30-day readmission (odds ratio, 4.29; 95% confidence interval, 3.20–5.76), reoperation (odds ratio, 3.97, 95% confidence interval, 2.63–6.00), and mortality rates (odds ratio, 5.95, 95% confidence interval, 2.62–13.48), all P < .001. Bivariate analysis identified a statistically significant association between several patient characteristics, operation, and hernia- related details; however, multivariate analysis revealed that that only hernia width (each increasing centimeter: odds ratio, 1.07, 95% CI, 1.05–1.09) and operative time compared with 0–59 minutes (60–119 minutes: odds ratio, 4.23; 95% confidence interval, 1.86–9.62; 120–179 minutes: odds ratio, 5.78; 95% confidence interval, 2.57–13.0; 180–239 minutes: odds ratio, 8.01; 95% confidence interval, 3.54–18.10; and 240+ minutes: odds ratio, 17.4; 95% confidence interval, 7.88–38.37) were significantly associated with venous thromboembolism risk. ConclusionsVenous thromboembolism is an uncommon complication of ventral hernia repair. It is associated with increased readmission, reoperation, and mortality rates. Larger defect width and operative time are most predictive of perioperative venous thromboembolism risk for patients undergoing ventral hernia repair.

Social Capital and Surgery Access Among Medicare Beneficiaries.

To compare the rates of unplanned procedures for access-sensitive surgical conditions among beneficiaries living in census tracts of varying social capital levels. Access-sensitive surgical conditions are conditions ideally screened for and treated in an elective setting. However, when left untreated, these conditions may result in unplanned (i.e., urgent or emergent) surgery. It is possible that social capital-the resources available to individuals through their membership in a social network-may impact the likelihood of a planned procedure occurring. Medicare beneficiaries who underwent one of three access-sensitive procedures (abdominal aortic aneurysm repair, colectomy for cancer, and ventral hernia repair) between 2016-2020 were stratified by their census tract level of social capital, the exposure variable. Outcomes included rate of unplanned surgery, readmission, 30-day mortality, and complications which were risk-adjusted with a logistic regression model that accounted for patient age, sex, race, comorbidities, and area deprivation. A total of 975,048 beneficiaries were included (mean [SD] patient age, 76 [7.6] years; 443,190 were male [45.45%]). Compared to patients from census tracts in the highest overall social capital decile, those from census tracts with the least social capital were on average more likely to undergo unplanned surgery (40.67% versus 35.28%, OR=1.26 P<0.001). Additionally, beneficiaries in these communities were also more likely to experience postoperative complications (24.99% versus 22.90%, OR=1.12 P<0.001), but there was no significant difference in rates of readmission or mortality. When evaluating only elective procedures, the differences between the lowest and highest social capital decile groups reduced significantly for complications (12.77% versus 12.11%, OR=1.06 P=0.04), the differences in mortality rates collapsed, and differences in readmission rates remained insignificant. These data suggest that Medicare beneficiaries who live in communities with lower social capital are more likely to undergo unplanned surgery for access-sensitive conditions. Efforts to improve social capital in these communities may be one strategy for reducing the rate of unplanned operations.

Flu-like symptoms following botulinum toxin A application before incisional hernia repair: A case report

Abstract Botulinum toxin has been used for the treatment of numerous medical conditions. Recently, preoperative botulinum toxin A (BTA) injections into the lateral abdominal wall muscles are beneficial for facilitating ventral hernia repairs and improving surgical outcomes. Early and late, local and systemic adverse effects of BTA application have been described, some of them are flu-like symptoms (FLS). However, no case of FLS following botulinum toxin injections before ventral hernia repair has been described. In this report, we present a 58-year-old female patient who developed FLS episodes throughout preoperative and postoperative periods following BTA injections.

Is surgeon annual case volume related with intra and postoperative complications after ventral hernia repair? Uni- and multivariate analysis of prospective registry-based data

BackgroundLiterature on a potential relationship between surgeon case volume and intra- or postoperative complications after ventral hernia repair remains scarce.MethodsPatients who underwent ventral hernia repair between 2011 and 2023 were selected from the prospectively maintained French Hernia-Club Registry. Outcome variables were: intraoperative events, postoperative general complications, surgical site occurrences, surgical site infections, length of intensive care unit (ICU), and patient-reported scar bulging during follow-up. Surgeons’ annual case volume was categorized as 1–5, 6–50, 51–100, 101–125, and > 125 cases, and its association with outcome volume was evaluated using uni- and multivariable analyses.ResultsOver the study period, 199 titular or temporary members registered 15,332 ventral hernia repairs, including 7869 primary, 6173 incisional, and 212 parastomal hernia repairs. In univariate analysis, surgeons’ annual case volume was significantly related with all the postoperative studied outcomes. After multivariate regression analysis, annual case volume remained significantly associated with intra-operative complications, postoperative general complications and length of ICU stay. A primary repair was independently associated with fewer intra- and post-operative complications.ConclusionIn the present multivariable analysis of a large registry on ventral hernia repairs, higher surgeon annual case volume was significantly related with fewer postoperative general complications and a shorter length of stay, but not with fewer surgical site occurrences, nor with less patient-reported scar bulging. Factors in the surgeons’ case mix such as the type of hernia have significant impact on complication rates.

Examining Clinical Practice and Short-Term Results in Ventral Hernia Repair

Background and Objectives: This prospective observational study conducted at Parul Sevashram Hospital, Vadodara aimed to examine the diversity in surgical techniques used for primary and incisional ventral hernia repair (VHR). Methods: Twenty-five elective VHR patients treated from January 1, 2023, to March 31, 2023, were enrolled. Patients were monitored for 90 days post-surgery. Exclusion criteria included patients under 18 years old and those undergoing emergency surgeries. The primary objective was to compare surgical approaches between primary and incisional hernia repairs. Secondary objectives focused on intraoperative procedures such as mesh selection, fixation techniques, and drain placement, as well as evaluating postoperative outcomes at 3 months, including infection rates, surgical site issues, mortality, and readmission rates within 90 days. Results: Data from 25 patients were analysed: 14 (58%) had primary hernias (PH) and 11 (42%) had incisional hernias (IH), including 1 (9.09%) recurrent case. – PH Group: Procedures included 6 (42.85%) open Onlay, 4 (28.57%) open Sublay, 1 (7.14%) intraperitoneal Onlay meshplasty (IPOM), and 3 (21.42%) suture repairs. Complications: 7% seroma, 0% surgical site infection (SSI), 0% recurrence. – IH Group: Procedures included 7 (63.63%) open Onlay, 3 (27.3%) open Sublay, and 1 (9.09%) suture repair. Complications: 9% seroma, 9% hematoma, 0% SSI, 9% wound sinus, 0% recurrence. Conclusion: Onlay meshplasty emerged as the predominant procedure for both primary and incisional hernias. However, open Sublay repair showed promising results with fewer seroma-related complications. Standardizing guidelines could optimize outcomes in VHR.

Long-term results with biosynthetic absorbable P4HB mesh in ventral abdominal wall repair: a multicentre analysis.

The aim of this multicentre study was to analyse the outcomes of biosynthetic absorbable poly-4-hydroxybutyrate (P4HB) prosthesis implantation in patients undergoing ventral hernia repair (VHR) in the context of different degrees of contamination. From May 2016 to December 2021, a multicentre retrospective analysis of patients who underwent elective or urgent hernia repair with P4HB prosthesis was performed in seven hospitals in Spain and Portugal. Patients with a postoperative follow-up of less than 20months and those within the theoretical period of prosthesis resorption were excluded from the study. Regarding the degree of contamination, patients were assessed according to the modified Ventral Hernia Working Group (VHWG) classification. Epidemiological data, hernia characteristics, surgical and postoperative variables (Clavien-Dindo classification) of these patients were analyzed. Risk factors related to long-term recurrence were studied by a multivariate analysis. In 236 cases of P4HB prosthesis implantation, repair in cases of Grade 3 was the most frequent (49.1%), followed by Grade 2 in 42.3% of cases and Grade 1 in 8.4%. The most frequent complications were Grade 1, with the majority occurring during the first year. The overall rate of surgical site occurrences (SSO) was 30%. The hernia recurrence rate was 14.4% (n = 34), with a mean postoperative follow-up time of 41months (22-61). The multivariate analysis showed that the onlay location of the mesh (OR 1.07; CI 1.42-2.70, p = 0.004) was a significant independent risk factor for recurrence. The use of a P4HB bioresorbable mesh for the VHR with different degrees of contamination leads to favourable results overall, with an acceptable rate of hernia recurrence. The onlay location of the P4HB prosthesis is the main factor in recurrence in both elective and emergency settings.

Retrorectus Ventral Hernia Repair Utilizing T-line Hernia Mesh: Technical Descriptions.

The T-line hernia mesh is a synthetic, polypropylene mesh with mesh suture extensions designed to prevent anchor point failure by evenly distributing tension across the soft tissue. Previous studies have demonstrated the success of onlay ventral hernia repair with T-line hernia mesh, but retrorectus applications of the mesh have not yet been characterized. This technique article illustrates technical descriptions and clinical applications of the T-line hernia mesh in the retrorectus plane.
