Patient expectations and decisional regret in the management of ventral hernias.

INTRODUCTION: Older adult patients have many factors to contemplate when considering elective ventral hernia repair. In this study, we aimed to understand whether our novel shared decision-making (SDM) aid helped reduce this population's decisional regret when choosing hernia management strategy. METHODS: Patients ≥ 60 years of age presenting for ventral hernia evaluation were randomized to two groups. The experimental group had their visit guided by our novel SDM aid. All patients took a survey prior to consultation outlining their treatment expectations. All patients were called within 6 months to complete the Decision Regret Scale, which measures remorse after a healthcare decision. RESULTS: Seventy-two patients (36 control, 36 experimental) completed final follow-up. On initial expectations evaluation, 53 patients (74%) reported wanting surgical repair and 58 patients (81%) reported expecting surgical repair. Ultimately, 18 patients in the control group and 17 patients in the experimental group did not undergo surgery. The use of the SDM aid did not affect if patients chose observation (OR 0.44, p = 0.24) or result in a lower decision regret score (9.86 vs 9.31, p = 0.89). Surgery was associated with a lower decision regret score (3.38 vs 16.14; p = 0.001). Of those who did not undergo repair, patients initially wanting or expecting surgery had higher decision regret scores (22.83 vs 3.33, p < 0.001; 20.40 vs 5.50, p = 0.009). Nonoperative patients who chose observation had less regret than those needing medical optimization (9.50 vs 25.00, p = 0.04). There were no differences in decision regret scores based on initial wants or expectations for those who had surgical repair. CONCLUSION: Decisional regret following ventral hernia management is associated with patients' expectations prior to initial surgical consultation. The use of a decisional aid did not lower decision regret scores. These findings emphasize the need for upfront expectation setting and longitudinal programs to help patients reach their treatment goals.

Long-term patient reported outcomes after robotic, laparoscopic, and open ventral hernia repair.

INTRODUCTION: Current evidence demonstrates questionable incremental benefit of robotic abdominal wall (ventral) hernia repair when compared to other approaches. However, data are mainly limited to 30-day outcomes and do not capture long-term patient reported outcomes (PROs) where the robotic may provide distinct advantages. METHODS: We analyzed patients who underwent ventral hernia repair from January 2020-September 30, 2022 in the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry (MSQC-COHR). Validated PROs included the Ventral Hernia Recurrence Inventory (VHRI), PROMIS Pain Intensity 3a (Pain 3a), and HerQLes quality of life measures. Survey weighting was employed to reduce non-response bias and balance respondents with the overall COHR population. Logistic regression was used to assess the relationship of operative approach with answering "Yes" to the 3 VHRI questions, reporting a worse than average Pain 3a score, and reporting a below median HerQLes score. Models accounted for patient, hernia, and operative characteristics. RESULTS: Our sample included 1583 patients undergoing hernia repair, of which 507 (32.0%) were robotic, 202 (12.8%) were laparoscopic, and 874 (55.2%) were open. Median follow up time was 1.3 years (IQR 1.2-1.5). Patient characteristics were similar across approaches. Robotic repairs were more often performed electively, on larger hernias, and with mesh. After controlling for covariates, a robotic approach was associated with a lower predicted probability of reporting a bulge [19.5% (95% CI 15.7-23.2%)] than a laparoscopic approach [26.8% (95% CI 20.4-33.2%)], but was no different than an open approach [18.8% (95% CI 16.1-21.6%)]. No other differences in PROs were found by approach. CONCLUSIONS: We found a lower likelihood of reporting a bulge after robotic ventral hernia repair when compared with a laparoscopic approach, but no difference when compared with an open approach. No other differences in long-term PROs were found when comparing robotic to laparoscopic or open approaches.

A systematic review and meta-analysis of randomized controlled trials for the management of ventral hernia: biologic versus synthetic mesh.

An abdominal wall hernia near the location of a prior surgical incision is referred to as an incisional hernia. A midline incisional hernia is the most prevalent form. The management of incisional hernia includes many options, from conservative to surgical. The surgeon might consider using a synthetic or biological mesh when discussing surgical options with patients. Our aim through this study is to comprehensively compare synthetic and biological mesh in terms of complication and infection rates for managing elective incisional hernia. This systematic review was designed and conducted using PRISMA guidelines. The literature was systematically searched in January 2023 using the following databases: MEDLINE, Cochrane, and EMBASE. Among the terms used to aid the search were the following: incisional hernia, ventral hernia, ventral herniorrhaphy, biologic mesh, polypropylene mesh, absorbable mesh, permanent mesh, biomaterial mesh, biological mesh, and synthetic mesh. The review of the literature resulted in a total of 3115 publications. By applying our criteria, six articles were included in this study, with 949 participants. Our meta-analysis showed the overall complication incidence displaying a significant difference favouring the synthetic mesh group (IV = 1.25, 95% CI 1.11-1.42, P = 0.0002). The operation failure rate, defined as hernia recurrence, also significantly favoured synthetic mesh (IV = 2.42, 95% CI 1.66-3.52, P < 0.00001). In conclusion, the present study found that the synthetic mesh proved superior in overall complication rate and operation failure compared to biologic mesh. However, it had no significant differences in other complications.

Comparing procedural costs and early clinical outcomes of robotic extended totally extraperitoneal (eTEP) with intraperitoneal onlay mesh (IPOM) repair for midline ventral hernias.

INTRODUCTION: The extended totally extraperitoneal (eTEP) repair has several theoretical advantages over the traditional intraperitoneal onlay mesh (IPOM) repair for ventral hernias, including the use of less expensive non-barrier coated mesh and avoiding complications of intraperitoneal mesh. However, one area in need of further investigation is cost and clinical comparisons following robotic eTEP with IPOM. METHODS: A retrospective matched cohort study was conducted of patients with midline ventral hernias undergoing robotic eTEP or IPOM at a single academic institution from November 2019-August 2023. Patients were matched based on demographics, hernia defect size, and whether they underwent concomitant procedures. Primary outcomes included supply costs. Secondary outcomes included operative time, length of stay, complications, recurrence, and inpatient opioid utilization. RESULTS: In total, 88 matched patients were included: 44 IPOM and 44 eTEP. Mean age was 57 years, BMI 35 kg/m2, and 54.5% were male. Hernia size was similar for both groups: 25 [6-73] cm2 for the IPOMs vs 40 [14-68] cm2 for eTEPs (p = 0.21). There was no significant difference in total supply costs between IPOMs and eTEPs: $2338 [2021-3249] vs $2082 [1619-3394] (p = 0.5) respectively. Mean operative time was significantly lower for IPOMs 159.6 ± 57.8 min vs 198.0 ± 67.1 (p = 0.006), while the average length of stay was significantly longer for IPOMs: 1.7 ± 1.2 days vs 1.2 ± 1.3 days (p = 0.021). Total inpatient MME utilized was greater for IPOM: 61 [36-102] vs 29 [10-64] MME (p = 0.003). Postoperative complications and recurrence rate were similar. CONCLUSION: There is no difference in total supply costs between patients undergoing robotic IPOM and eTEP repairs for midline ventral hernias. Though this study did find significant differences in total inpatient MME utilized and length of stay, it is debatable whether these are clinically significant. Further research is needed to determine appropriate indications for eTEP over IPOM.

Application of Closed Incision Negative Pressure Wound Therapy in Ventral Hernia Repair Surgery Using a Polypropylene Mesh: A Randomized Clinical Trial.

Background and Objectives: Surgical site infections (SSIs) are a significant complication following ventral hernia repair, potentially leading to prolonged hospital stays and increased morbidity. This study aimed to evaluate whether closed incision negative pressure wound therapy (ciNPWT) reduces the incidence of SSI after ventral hernia repair with polypropylene mesh compared to standard wound care. Materials and Methods: A randomized study was conducted with 100 patients undergoing ventral hernia repair using a polypropylene mesh. Participants were divided into two groups: a control group (n=50), which received standard sterile gauze dressing with an iodine-based disinfectant, and an intervention group (n=50), treated with the ciNPWT system (Vivano® by HARTMANN) for 5 days postoperatively. The primary outcome was the incidence of SSI within one year after surgery. Secondary outcomes included the influence of factors such as age, sex, smoking status, and hernia size on SSI occurrence. The study was approved by the Ethics Committee at the University Hospital Ostrava, adhering to the ethical standards of the Helsinki Declaration. Results: The incidence of SSI was lower in the ciNPWT group compared to the standard care group (4% vs. 12%), though this difference did not reach statistical significance. No significant effect of sex or smoking status on SSI was observed. The control group had a shorter mean length of hospital stay. Larger hernias in the non-ciNPWT group were more prone to SSIs, as expected. Conclusions: Although limited by a small sample size, the findings suggest that ciNPWT may be associated with a reduced rate of SSI following ventral hernia repair. Further studies with larger populations are needed to confirm these results.

Mesh exposure after ventral hernia repair with onlay biosynthetic mesh: a retrospective review of associated risk factors and management strategies.

BACKGROUND: Although intraperitoneal and retromuscular mesh placement in ventral hernia repair (VHR) are associated with lower recurrence rates, the onlay plane remains a well-established option for certain clinical scenarios. A knowledge gap remains regarding resorbable biosynthetic onlay mesh and mesh exposure. We aim to determine exposure rate, risk factors, and treatment options. STUDY DESIGN: A single-center, two-surgeon retrospective review was performed examining patients who underwent VHR with onlay, Poly-4-hydroxybutyrate (P4HB) mesh from 2015 to 2021. Demographics, operative characteristics, outcomes, and mesh exposure management were analyzed. RESULTS: Of 346 patients, 15 (4.3%) experienced mesh exposure. The mean age was 53 years and BMI of 33.6 kg/m2. Patients were majority ASA class 3 (65%), female (64.2%), and averaged a defect size of 307.9 ± 235.2 cm2. Independent risk factors included diabetes (AOR = 4.3,CI 1.5-12.5;p < 0.005) and COPD (AOR = 5.2,CI 1.3-21.8;p = 0.02). Mesh exposures were identified as outpatient (20%) or intraoperative (80%). All underwent operative debridement, in which nine were managed with skin reclosure, two with partial closure, and four healed by secondary intention. Five patients required excision of unincorporated mesh. Four patients required further debridement from chronic surgical site occurrences; however, all mesh exposure patents healed after a mean of 260.8 ± 313.2 days and retained original mesh. The recurrence rate was 6.7% for mesh exposure patients. CONCLUSION: When faced with mesh exposure, resorbable biosynthetic mesh placed in onlay fashion was retained in all patients. Patients with a history of diabetes or COPD have increased risk of mesh exposure and should be counseled.

Preoperative botolinum toxin A (BTA) and intraoperative fascial traction (IFT) in the management of complex abdominal wall hernias.

INTRODUCTION: Preoperative botolinum toxin A (BTA) administration to the lateral abdominal wall has been widely used since its introduction for treating complex abdominal wall defects and loss of domain (LOD) hernias. Intraoperative fascial traction (IFT) is an established technique for complex abdominal wall hernias exceeding a width of 10 cm and has also shown auspicious results. We present our single center data including 143 consecutive cases combining both techniques from 2019 to 2023. Aim of the study was to develop an algorithm for a tailored approach for very large and complex ventral abdominal wall hernias. METHODS: Consecutive patients treated with preoperative BTA and IFT from August 2019 to December 2023 were identified in our prospectively maintained database and reviewed retrospectively. Metrics included intraoperative findings and short-term (30 days) postoperative outcomes. RESULTS: 143 patients were included in our retrospective analysis. The mean age was 58.9 years and 99% of all patients had an ASA Score of II or III with a mean body mass index of 32.4 kg/m2. The mean intraoperative reduction of fascia-to-fascia after BTA and IFT was 9.81 cm. 14 patients either had a lateral defect or a combination of a midline and lateral hernia. An additional uni- or bilateral transverse abdominis release (TAR) was necessary in 43 cases (30.1%). The overall surgical site occurrence rate (SSO) was 30.1% of which 13.8% were surgical site infections (SSI). Re-operation and SSO rates were significantly higher if an additional TAR was performed (both p = 0.001; α = 0.05). CONCLUSIONS: IFT in combination with BTA is a transformative and clinically proven tool in the surgeons' toolbox. It might be an easier, and less invasive alternative to other available techniques in many cases, but it should not be looked at as an ultimate stand-alone method to treat all complex W3 hernias.

Socioeconomic inequalities in patients undergoing abdominal wall reconstruction in the North-West of England, UK: a three-centre retrospective cohort study.

PURPOSE: Patients from deprived areas are more likely to experience longer waiting times for elective surgery, be multimorbid, and have inferior outcomes from elective and emergency surgery. This study aims to investigate how surgical outcomes vary by deprivation for patients undergoing elective abdominal wall reconstruction. METHODS: A three-centre retrospective cohort study was conducted across three hospitals in North-West England, including patients with complex ventral hernias undergoing abdominal wall reconstruction between 2013 and 2021. Demographic data, comorbidities, and index of multiple deprivation quintiles were recorded. RESULTS: 234 patients (49.6% female), age 57 (SD 13) years, underwent elective abdominal wall reconstruction. Significantly higher unemployment rates were found in the most deprived quintiles (Q1 and Q2). There were more smokers in Q1 and Q2, but no significant deprivation related differences in BMI, diabetes, chronic kidney disease or ischaemic heart disease. There were also higher rates of Clavien-Dindo 1-2 complications in Q1 and Q5, but no difference in the Clavien-Dindo 3-4 outcomes. Patients in Q1 and Q5 had a significantly greater hospital length of stay. CONCLUSION: The association between deprivation and greater unemployment and smoking rates highlights the potential need for equitable support in patient optimisation. The lack of differences in patient co-morbidities and hernia characteristics could represent the application of standardised operative criteria and thresholds. Further research is needed to better understand the relationship between socioeconomic status, complications, and prolonged hospital length of stay.

The current role of barbed sutures in fascial closure of ventral hernia repair: a multicenter study using the abdominal core health quality collaborative database.

BACKGROUND: Barbed sutures (BS) have been increasingly used in the last two decades across surgical disciplines but little is known about how widespread their adoption has been in ventral hernia repair (VHR). The aim of this study was to document the use of barbed sutures in VHR in a multicenter database with associated clinical and patient-reported outcomes. METHOD: Prospectively collected data from the Abdominal Core Health Quality Collaborative database was retrospectively reviewed, including all adult patients who underwent VHR with fascial closure from 2020 to 2022. A univariate analysis compared patients with BS against non-barbed sutures (NBS) across the preoperative, intraoperative, and postoperative timeframes including patient-reported outcomes concerning quality of life and pain scores. RESULTS: A total of 4054 patients that underwent ventral hernia repair with BS were compared with 6473 patients with non-barbed sutures (NBS). Overall, BS were used in 86.2% of minimally invasive ventral hernia repairs and about 92.2% of robotic surgery compared to only 9.6% of open procedures. Notable differences existed in patient selection, including a higher BMI (32 vs 30.5; p < 0.001), more incisional hernias (63.3% vs 51.1%; p < 0.001), wider hernias (4 cm vs 3 cm; p < 0.001), and higher ASA score (p < 0.001) in patients with BS. Outcomes in patients with BS included a shorter length of stay (mean days; 1.4 vs 2.4; p < 0.001), less SSI (1.5% vs 3.6%; p < 0.001), while having similar SSO (7.6% vs 7.3%; p = 0.657), readmission (3.0 vs 3.2; p = 0.691), and reoperation (1.5% vs 1.45%; p = 0.855), at a longer operative time (p < 0.001). Hernia-specific questionnaires for quality of life (HerQLes) and pain in patients with BS had a worse preoperative score that was later matched and favorable compared to NBS (p = 0.048). PRO concerning hernia recurrence suggest around 10% at two years of follow-up (p = 0.532). CONCLUSION: Use of barbed sutures in VHR is widespread and highly related to MIS. Outcomes from this multicenter database cannot be reported as superior but suggest that barbed sutures do not have a negative impact on outcomes.

Evaluation of risk factors associated with the peritoneal flap hernioplasty for complex incisional hernia repair - a retrospective review of 327 cases.

BACKGROUND: Repair of large incisional hernias is challenging, and the risks of postoperative complications have been associated with obesity, smoking, and diabetes. The present study was conducted to determine the impact of these risk factors on short and long-term outcomes following the repair with the peritoneal flap hernioplasty (PFH). METHODS: Three hundred twenty-seven patients undergoing PFH for incisional hernia repair were identified. Patient demographics and clinical data were recorded. Patients presenting signs of complications were assessed during a visit to the outpatient clinic. A multivariable regression analysis was performed to evaluate the association between BMI, smoking and diabetes, and postoperative complications. RESULTS: The study included 157 males (48.0%) and 170 females (52.0%). Median BMI was 30.9 kg/m2. Diabetes was present in 13.8% of patients. 23.2% were active smokers. The recurrence rate was 2.4%. The odds ratios for postoperative complications were increased by 9% per BMI unit (P < 0.01), due predominantly to a rise in superficial wound infections (P < 0.01) and seroma production (P = 0.07). The adjusted odds ratio increased fourfold in patients with BMI > 40 kg/m2 (P = 0.06). CONCLUSION: Incisional hernia repair with the PFH technique is associated with a low risk of short and long-term complications. The risk is associated with obesity and significantly increased in patients with a BMI exceeding 40 kg/m2, where a fourfold increase was observed predominantly due to seroma and superficial wound infections. The recurrence rate was 2.4% and was unaltered across BMI categories. No association was established between smoking, diabetes, and the risk of all-cause complications.

The impact of simultaneous panniculectomy in ventral hernia repair: a systematic review and meta-analysis.

BACKGROUND: Ventral hernia repair (VHR) is often performed in patients with obesity. While panniculectomy improves cosmetic outcomes, it may increase complications, particularly wound-related adverse events. Despite its widespread use, the impact of concurrent panniculectomy on postoperative complications in VHR remains unclear. This study aimed to assess whether concurrent panniculectomy increases postoperative complications in VHR. METHODS: We searched PubMed, Scopus, Web of Science, and Cochrane databases for studies published up to April 2024 comparing surgical outcomes in patients undergoing VHR with and without concurrent panniculectomy. We assessed recurrence, seroma, hematoma, surgical site infections (SSI), wound dehiscence, skin necrosis, chronic wound, length of stay (LOS), readmissions, duration of surgery, and deep venous thromboembolism (DVT). Risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs) were pooled for dichotomous and continuous endpoints, respectively. We used RStudio for statistics and heterogeneity was assessed with I2 statistics. RESULTS: We screened 890 studies, fully reviewed 40, and included 11 observational studies and 2 randomized controlled trials, comprising 23,354 patients. Of these, 2,972 (13%) patients underwent VHR with concurrent panniculectomy (VHR-PAN). The mean age ranged from 37 to 59 years, and 73% of the sample were women. The mean BMI varied from 29 to 45 kg/m2, and 75% of the patients underwent mesh repair. The mean defect area ranged from 36 to 389 cm2. Most repairs were performed using mesh (75%) in an underlay position (68%) and 24% underwent component separation. VHR-PAN was associated with a decrease in recurrence rates (RR 0.74; 95% CI 0.62 to 0.89; p < 0.001; I2 = 1%) with a follow-up ranging from 1 to 36 months. Furthermore, subgroup analysis of recurrence in studies with a mean follow-up of at least one year also showed a reduction in recurrence (RR 0.72; 95% CI 0.60 to 0.88; p < 0.001; I2 = 12%), with a follow-up ranging from 12 to 36 months. Moreover, concurrent panniculectomy was associated with increased SSI (RR 1.31; 95% CI 1.13 to 1.51; p < 0.001; I2 = 0%), SSO (RR 1.49; 95% CI 1.26 to 1.77; p < 0.001; I2 = 11%), skin necrosis (RR 2.94; 95% CI 1.26 to 6.85; p = 0.012; I2 = 0%) and reoperation (RR 1.73; 95% CI 1.32 to 2.28; p < 0.001; I2 = 0%), and longer LOS (MD 0.90 day; 95%CI 0.40 to 1.40; p < 0.001; I2 = 56%). There was no significant difference in ocurrence of DVT, enterocutaneous fistula, hematoma, seroma, or wound dehiscence, neither on operative time or readmission rates. CONCLUSION: VHR-PAN is associated with lower recurrence rates. However, it increases the risk of wound morbidity and reoperation and prolongs hospital stay. Surgeons should carefully weigh the risks and benefits of performing VHR-PAN. STUDY REGISTRATION: A review protocol for this systematic review and meta-analysis was registered at PROSPERO (CRD42024542721).

Videoendoscopic assisted Rives-Stoppa technique. "Treatment for epigastric and umbilical hernias with diastasis recti".

PURPOSE: There are many surgical techniques for ventral hernias and diastasis recti, both conventional or video-endoscopic, with or without mesh placement, detailed in the literature. Using some details of the techniques proposed by Wolfgang Reinpold (Mini- or Less Open Sublay Operation, MILOS) and Federico Fiori (Totally Endoscopic Sublay Anterior Repair, TESAR) we found modifications that allowed repairing and reinforcement of the posterior fascia with a retro-muscular mesh and achieve primary fascial closure by minimally umbilical access and searching for the best anatomical, functional, and aesthetic results. METHOD: Describe the surgical technique step by step and analyze 629 surgical treatments. The cohort comprises the period January 2018 to January 2023. Our Database registered 318 men and 311 women who underwent video endoscopicassisted Rives-Stoppa techniques to treat umbilical and epigastric hernias with diastasis RESULTS: All patients were treated on an outpatient basis and discharged home on the same day. The most frequent complications were seromas with conservative management. Other complications recorded were omphalitis in 6 patients, and three patients presented hematomas, one of whom performed surgical evacuation. There were ten patients with recurrences. CONCLUSION: These hybrid approaches provide the advantages of mini-invasive techniques with a lower rate of complications and a high standard of quality of life, providing anatomical, functional, and aesthetic benefits.

The impact of diabetes and presurgical glycemic control on wound morbidity following open complex abdominal wall reconstruction: a single-center experience.

INTRODUCTION: Numerous studies have identified diabetes mellites (DM) as a significant risk factor for postoperative wound morbidity, with suboptimal preoperative glycemic control (GC) posing an even greater risk. However, this data largely excludes ventral hernia patients. Our study examined the association between diabetes and preoperative GC and postoperative outcomes following open complex abdominal wall reconstruction (AWR). METHODS: We identified diabetic patients who had undergone open, elective, clean VHR with transversus abdominis release (TAR) and permanent synthetic mesh at the Cleveland Clinic Foundation between January 2014 and December 2023. Their 30-day outcomes were compared to non-diabetic patients undergoing the same procedure. Subsequently, diabetic patients were categorized based on GC. status: "Optimal GC" (HbA1c < 7%), "Sub-optimal GC" (HbA1c 7-8.4%), and "Poor GC" (HbA1c ≥ 8.5%) and their outcomes were compared. RESULTS: 514 patients with DM who underwent clean elective TAR were identified, of which 431 met the inclusion criteria. GC was deemed optimal in 255 patients, sub-optimal in 128, and poor in 48 patients. Demographics were similar, except for anticoagulation treatment (p = 0.014). The entire study population exhibited significantly higher rates of wound morbidities and overall complications compared to non-diabetic patients. However, rates of surgical site infection (SSI), surgical site occurrence (SSO), SSO requiring procedural intervention (SSOPI), and reoperation did not differ significantly among the three cohorts of presurgical glycemic control (p = 0.82, p = 0.46, p = 0.51, p = 0.78), respectively. No occurrence of mesh removal was documented. CONCLUSION: In general, diabetes is a marker for increased wound morbidity and complications following complex abdominal wall reconstruction. However, we could not establish a hard cutoff to justify withholding surgery in symptomatic patients based on an arbitrary HbA1C level. We believe this data is important for shared decision-making when considering AWR for symptomatic ventral hernias in diabetic patients.

Robotic preperitoneal extended totally extraperitoneal (R-PeTEP) technique description for ventral hernia repair: preliminary results.

PURPOSE: Transabdominal preperitoneal (TAPP) ventral hernia repair requires incising the peritoneum from within the abdominal cavity, developing a flap, and placing a reinforcing mesh after fascial closure from the preperitoneal space. We present a novel adaptation to this technique that allows placement of preperitoneal mesh without entering the abdominal cavity. The robotic totally extra- and preperitoneal (R-PeTEP) access for ventral hernia repair is best suited for small to moderate sized ventral hernias with concomitant diastasis recti. METHODS: Our study is a retrospective review of all patients who underwent R-PeTEP from December 2022 to November 2023. A comprehensive description of the surgical technique is included. Patient demographics, hernia characteristics, as well as clinical outcomes are described. RESULTS: A total of 25 patients underwent R-PeTEP for ventral hernia repair with diastasis recti plication. The median age was 55 years (IQR 43.5-63) and 92% (n = 23) were male. The median ASA score was 2 (IQR 1-2) and the median BMI was 30.4 (IQR 29.3-32.8) with 64% (n = 16) percent having a BMI ≥ 30. Median hernia width was 3 cm (IQR 3-4), with a median diastasis recti width of 4 cm (IQR 2.6-4) and length of 15 cm (IQR 11.8-16). The median operative time was 120 min (IQR 116-134). All repairs were reinforced with permanent mesh. Sixty-eight percent of the patients (n = 17) were discharged on the same day. With a median follow-up of 30 days (IQR 16-107), 8% (n = 2) seromas, 16% (n = 4) developed clinically insignificant hematomas, and one patient (4%) developed ileus that was managed conservatively. CONCLUSION: This study establishes the feasibility and safety of R-PeTEP, which provides direct access to the preperitoneal space, avoiding disruption to the posterior rectus sheath, possibly reducing neurovascular bundle injuries, and omitting entry to the abdominal cavity. R-PeTEP facilitates wide flap creation for prosthetic overlap and allows for posterior plication of diastasis recti with little to no mesh fixation with overall excellent preliminary clinical outcomes.

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.

Purpose: 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). Methods: 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. Results: 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. Conclusion: 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.

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

BACKGROUND: 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. METHODS: Using the 2015-2022 MBSAQIP database, patients aged 18-65 years 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. RESULTS: 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 ± 38.45 min, p < 0.001), and in RYGB + VHR-M (141.91 ± 58.68 vs. 128.47 ± 62.37 min, 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. CONCLUSION: 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.

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

BACKGROUND: 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. METHODS: 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 7-15 cm 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. RESULTS: 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 8 cm, 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 2 days; p < 0.001). All patients had significant improvement in quality of life at 1 and 2 years. Other secondary outcomes were similar. CONCLUSION: There is no difference in a composite outcome including SSI, SSOPI, readmission, and hernia recurrence between open and robotic RMVHR.

Short-Term Outcomes of Transabdominal Preperitoneal Ventral Hernia Repair With Rectus Aponeuroplasty (TAPPRA) for the Management of Incisional Hernias.

Introduction: Options for minimally invasive ventral hernia repair continue to evolve as a function of our understanding of the abdominal wall and the development of new techniques. We describe a robotic transabdominal pre-peritoneal repair with concurrent rectus aponeuroplasty (TAPPRA) for incisional and recurrent ventral hernias. Methods: All patients in this retrospective cohort study underwent TAPPRA repair between October 2023 and March 2024. This study aimed to determine intraoperative feasibility of the technique and to assess immediate postoperative outcomes. Results: Twelve patients underwent TAPPRA repair for incisional and/or recurrent ventral hernias at an academic hernia center. The median case duration was 135 min with no significant intraoperative complications noted. Average defect size for the hernias measures 6.5 × 8.5 cm. Polypropylene mesh was used to reinforce all defects, with the average dimensions being 19.7 × 21.5 cm. 83% of patients were discharged within 24 h of their procedure. No significant postoperative complications were noted. Conclusion: We describe the first use of a novel ventral hernia repair technique, TAPPRA, and demonstrate that it is safe, feasible, and associated with appropriate short-term outcomes for repair of moderate sized incisional hernias.

Synchronous cesarean delivery and revision of infected ventral hernia repair mesh in a complex abdominal wall.

Ventral hernias are a common abdominal wall defect vulnerable to the gravid abdomen's physiological changes. This case report describes a 38-year-old gravida 3 para 2002 female with a complex abdominal surgical history and a chronic infection of the abdominal wall at the site of prior hernia repair with mesh. She was managed conservatively with antibiotics until delivery. Abdominal wall debridement and repair was coordinated with her 39-week cesarean, which allowed for a successful delivery of her infant paralleled with surgical management of the infected mesh.

Classifying frailty in the ventral hernia population.

INTRODUCTION: Frailty is increasingly recognized as a preoperative predictor of adverse outcomes following various surgical procedures. Our study aims to compare validated frailty measures in the ventral hernia population, as this is a common elective procedure with a paucity of data regarding frailty prevalence. METHODS: Patients aged 18 years or older with planned ventral hernia repairs were prospectively enrolled in our single-institution study from January 2023 through June 2023. After obtaining informed consent, patients completed the Fried Frailty Index (FFI), the FRAIL Scale, and the Strength, Assistance walking, Rising from a chair, Climbing stairs, and Falls (SARC-F) questionnaires, as well as the standard completion of the Patient-Reported Outcomes Measurement Information System (PROMIS) measures at their preoperative clinic appointment. Chart review was performed for baseline demographics and comorbidities. The Modified Frailty Index (mFI-11) and the Charleston Comorbidity Index (CCI) were calculated. RESULTS: A total of 63 patients were enrolled in our study. On average, the population was 60 years old, with a BMI of 32.4 kg/m2, a CCI of 3, and on 10.5 medications preoperatively. Overall, 12 patients (19%) screened positive for frailty by the mFI-11, 17 patients (27%) by the FFI, 15 patients (23.8%) by the FRAIL Scale, and 15 patients (23.8%) screened positive for sarcopenia by SARC-F. The FFI and the FRAIL Scale were strongly correlated with the other measures by Spearman's rank-order correlation (p < 0.05). On multivariate regression analysis, a longer Timed Up and Go test was associated with screening positive for frailty or sarcopenia (OR 1.896, p = 0.016). CONCLUSION: In this study, we find that frailty is more prevalent than previously reported in the literature by any measure used. Both the FRAIL Scale and FFI strongly correlate with the other tools investigated. Surgeons should consider using these assessments preoperatively to estimate frailty and guide operative planning as well as shared decision-making.
