Ventral Hernia Repair Research Articles

Early results of eTEP access surgery with preperitoneal repair of primary midline ventral hernias and diastasis recti. A 33 patient case series of "PeTEP".

This article aims to share the initial experience of the preperitoneal eTEP approach and its potential benefits in a selected group of patients. The eTEP Rives-Stoppa is a proven minimally invasive surgical technique for the treatment of ventral midline and off-midline hernias that has shown to be a solid, durable, and reproducible repair. The preperitoneal eTEP repair is a surgical technique that brings together the extraperitoneal access surgery with a preperitoneal repair for primary midline hernias avoiding posterior rectus sheath division and preservation of the retrorectus space while being able to treat simultaneous diastasis recti. The analysis included 33 patients operated with thepreperitoneal eTEP approach from September 2022 to September 2023 in patients with primary small to medium (< 4cm) midline hernias, single or multiple defects with or without diastasis recti. Age, gender, hernia characteristics, operative time, and surgical site occurrences will be discussed, as well as fine details and landmarks in the operative technique. 33 consecutive patients were operated, 19 female (57.5%) and 14 males (42.5%) between 32 and 63years of age, the most common comorbidity found was obesity (BMI > 30). In 70% of the cases, operative time was 90min ± 25min. The average hospital stay was one day, while 12 went home the same day, and so far, no reoccurrences have been reported. We believe the preperitoneal eTEP approach for small to medium primary midline hernias is an effective and solid repair that combines excellent features of proven surgical techniques and eliminates the need for posterior rectus sheath division while saving the retrorectus space, among other benefits that will be discussed. The reproducibility of the technique remains to be proven.

Evaluation of 30-day outcomes for open ventral hernia repair using self-gripping versus nonself-gripping mesh.

The use of mesh is standard of care for large ventral hernias repaired on an elective basis. The most used type of mesh includes synthetic polypropylene mesh; however, there has been an increase in the usage of a new polyester self-gripping mesh, and there are limited data regarding its efficacy for ventral hernia. The purpose of the study is to determine whether there is a difference in surgical site occurrence (SSO), surgical site infection (SSI), surgical site occurrence requiring procedural intervention (SSOPI), and recurrence at 30 days after ventral hernia repair (VHR) using self-gripping (SGM) versus non-self-gripping mesh (NSGM). We performed a retrospective study from January 2014 to April 2022 using the Abdominal Core Health Quality Collaborative (ACHQC). We collected data on patients over 18 years of age who underwent elective open VHR using SGM or NSGM and whom had 30-day follow-up. Propensity matching was utilized to control for variables including hernia width, body mass index, age, ASA, and mesh location. Data were analyzed to identify differences in SSO, SSI, SSOPI, and recurrence at 30 days. 9038 patients were identified. After propensity matching, 1766 patients were included in the study population. Patients with SGM had similar demographic and clinical characteristics compared to NSGM. The mean hernia width to mesh width ratio was 8cm:18cm with NSGM and 7cm:15cm with SGM (p = 0.63). There was no difference in 30-day rates of recurrence, SSI or SSO. The rate of SSOPI was also found to be 5.4% in the nonself-gripping group compared to 3.1% in the self-gripping mesh group (p < .005). There was no difference in patient-reported outcomes at 30 days. In patients undergoing ventral hernia repair with mesh, self-gripping mesh is a safe type of mesh to use. Use of self-gripping mesh may be associated with lower rates of SSOPI when compared to nonself-gripping mesh.

Predictors of postoperative opioid use in ventral and incisional hernia repair.

One in two ventral and incisional hernia repair (VIHR) patients have preoperative opioid prescription within a year before procedure. The study's aim was to investigate risk factors of increased postoperative prescription filling in patients with or without preoperative opioid prescription. VIHR cases from 2013 to 2017 were reviewed. State prescription drug monitoring program data were linked to patient records. The primary endpoint was cumulative opioid dose dispensed through post-discharge day 45. Morphine milligram equivalent (MME) was used for uniform comparison. 205 patients were included in the study (average age 53.5years; 50.7% female). Over 35% met criteria for preoperative opioid use. Preoperative opioid tolerance, superficial wound infection, current smoking status, and any dispensed opioids within 45days of admission were independent predictors for increased postoperative opioid utilization (p < 0.001). Preoperative opioid use during 45-day pre-admission correlated strongly with postoperative prescription filling in VIHR patients, and several independent risk factors were identified.

COMPARISON OF SURGICAL SITE INFECTION BETWEEN DIABETIC AND NON-DIABETIC PATIENTS IN CLEAN SURGICAL PROCEDURES

Surgical site infections (SSIs) are a major concern in healthcare, especially for individuals with diabetes. Diabetes can impair wound healing and weaken the immune system, increasing the risk of SSIs. Studying SSIs in diabetic versus non-diabetic patients undergoing clean surgeries is vital for improving patient care. Objective: The primary objective of this study was to investigate the incidence of surgical site infections (SSIs) in individuals with diabetes compared to those without diabetes who underwent clean surgical procedures. Methods: After the ethical approval from the institutional review board, this comparative study was conducted at Combined Military Hospital Jhelum from July 2022 to December 2023. A consisted of people with diabetes (n=50), while Group B comprised patients who did not have diabetes (n=50). All patients were administered suitable antibiotics before surgery. Each patient received a singular intravenous dose of Ceftriaxone 1g, administered thirty minutes before initiating the initial incision. The patients were monitored for surgical site infections (SSI), defined as the presence of redness, fever, tenderness at the incision site, discharge from the surgical wound, or the development of an abscess within 28 days after surgery. Results: Most participants in both study groups underwent open ventral hernia repair procedures, 54% in group A and 58% in group B. Mean± S. D of the Hb1Ac levels of the participants in both groups was 8.46±1.16 and 4.14±1.01 (P=&lt;0.0001). 58% of participants in Group A, while 22% in Group B had surgery-associated complications (p&lt;0.0001). 30% of participants in Group A, while 10% in Group B had SSI (p&lt;0.0001). Conclusion: Individuals with diabetes are more susceptible to experiencing higher rates of surgical site infection, especially in cases of procedures that are considered clean, in comparison to individuals without diabetes.

Computational Analysis and Classification of Hernia Repairs

Problems related to ventral hernia repairs (VHR) are very common, and evaluating them using computational methods can assist in selecting the most appropriate treatment. This study is based upon data from 3339 patients from different European countries observed during the last 12 years (2012–2023), which were collected by specialists in hernia surgery. Most patients underwent standard surgical procedures, with a growing trend towards laparoscopic surgery. This paper focuses on statistically evaluating the treatment methods in relation to patient age, body mass index (BMI), and the type of repair. Appropriate mathematical methods are employed to extract and classify the selected features, with emphasis on computational and machine-learning techniques. The paper presents surgical hernia treatment statistics related to patient age, BMI, and repair methods. The main conclusions point to mean groin hernia repair (GHR) complications of 19% for patients in the database. The accuracy of separating GHR mesh surgery with and without postoperative complications reached 74.4% using a two-layer neural network classification. Robotic surgeries represent 22.9% of all the evaluated hernia repairs. The proposed methodology suggests both an interdisciplinary approach and the utilization of computational intelligence in hernia surgery, potentially applicable in a clinical setting.

Endoscopic-assisted repair of combined ventral hernias and diastasis recti: minimizing seroma incidence by quilting.

To reduce the incidence of seromas, we have adapted the quilting procedure used in open abdominoplasty to the endoscopic-assisted repair of concomitant ventral hernia (VH) and diastasis recti (DR). The aim of this study was to describe the technique and assess its efficacy by comparing two groups of patients operated on with the same repair technique before and after introducing the quilting. This retrospective study included data prospectively registered in the French Club Hernie database from 176 consecutive patients who underwent surgery for concomitant VH and DR via the double-layer suturing technique. Patients were categorized into two groups: Group 1 comprised 102 patients operated before introducing the quilting procedure and Group 2 comprised 74 operated after introducing the quilting. To carry out comparisons between groups, seromas were classified into two types: type A included spontaneously resorbable seromas and seromas drained by a single puncture and type B included seromas requiring two or more punctures and complicated cases requiring reoperation. The global percentage of seromas was 24.4%. The percentage of seromas of any type was greater in Group 1 (27.5%) than in Group 2 (20.3%). The percentage of Type B seromas was greater in Group 1 (19.6%) than in Group 2 (5.4%), when the percentage of Type A seromas was greater in Group 2 (14.9) than in Group 1 (7.9%). Differences were significant (p = 0.014). The operation duration was longer in Group 2 (83.9 min) than in Group 1 (69.9 min). Four complications requiring reoperation were observed in Group 1: three persistent seromas requiring surgical drainage under general anesthesia and one encapsulated seroma. Adapting the quilting technique to the endoscopic-assisted bilayer suturing technique for combined VH and DR repair can significantly reduce the incidence and severity of postoperative seromas.

The Utilization of Laparoscopic Ventral Hernia Repair (LVHR) in Incarcerated and Strangulated Cases: A National Trend in Outcomes.

Early after its adoption, minimally invasive surgery had limited usefulness in emergent cases. However, with improvements in equipment, techniques, and skills, laparoscopy in complex and emergency operations expanded substantially. This study aimed to examine the trend of laparoscopy in incarcerated or strangulated ventral hernia repair (VHR) over time. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for laparoscopic repair of incarcerated and strangulated hernias (LIS-VHR) and compared over 2 time periods, 2014-2016 and 2017-2019. The utilization of laparoscopy in all incarcerated or strangulated VHR increased over time (2014-2016: 39.9% (n = 14 075) vs 2017-2019: 46.3% (n = 18 369), P < .001). Though likely not clinically significant, demographics and comorbidities statistically differed between groups (female: 51.7% vs 50.0%, P = .003; age 54.5 ± 13.7 vs 55.4 ± 13.8years, P < .001; BMI 34.9 ± 8.0 vs 34.6 ± 7.8kg/m2, P < .001). Patients from 2017 to 2019 were less comorbid (18.9% vs 16.8% smokers, P < .001; 18.2% vs 17.3% diabetic, P = .036; 4.6% vs 4.1% COPD, P = .021) but had higher ASA classification (III: 43.3% vs 45.7%; IV: 2.5% vs 2.7%, P < .001). Hernia types (primary, incisional, recurrent) were similar in each group. Operative time (89.7 ± 59.3 vs 97.4 ± 63.4min, P < .001) became longer but length-of-stay (1.4 ± 3.3 vs 1.1 ± 2.6days, P < .001) decreased. There was no statistical difference in surgical complications, medical complications, reoperation, or readmission rates between periods. Laparoscopic VHR has become a routine method for treating incarcerated and strangulated hernias, and its utilization continues to increase over time. Clinical outcomes have remained the same while hospital stays have decreased.

Outcomes and Quality of Life After Resorbable Synthetic Ventral Hernia Repair in Contaminated Fields.

The ideal mesh type for hernia repair in a contaminated field remains controversial. Data regarding outcomes beyond 1 year and the impact on quality of life (QoL) are unknown. This study aims to evaluate the long-term surgical outcomes and patient-reported outcomes (PROs) after contaminated repair with poly-4-hydroxybutyrate (P4HB) mesh. Patients undergoing a contaminated hernia repair with P4HB between 2015 and 2020 were identified. Surgical site occurrences and hernia recurrences were recorded. Long-term PROs as defined by the Abdominal Hernia-Q and Hernia-Related Quality-of-Life Survey were assessed. Fifty-five patients were included with a mean age of 54.5 years, a body mass index of 34 kg/m2, and a defect size of 356.9 ± 227.7 cm2. Median follow-up time was 49 months with a reoperation rate of 14.5% and a hernia recurrence rate of 7.3%. Of the 55 patients, 37 completed preoperative and postoperative PRO questionnaires. When comparing preoperative with postoperative Abdominal Hernia-Q, there was significant improvement in overall PROs (2.1 vs 3.5, P < 0.001). This improvement was maintained with no significant changes between postoperative scores over the course of 5 years. Patients with complications saw the same improvement in postoperative PRO scores as those without complications. Our study found a low hernia recurrence and acceptable long-term reoperation rates in patients undergoing hernia repair with P4HB mesh in a contaminated setting. We demonstrate a sustained significant improvement in QoL scores after hernia repair. These data yield insight into the long-term outcomes and QoL improvement, providing physicians further knowledge to better counsel their patients.

Evaluation of outcome of systemic tranexamic acid injection in drain output in ventral hernia repair

The primary objective of the study was to determine the mean drain output after systemic tranexamic acid injection in patients undergoing ventral wall hernia repair. This was a descriptive cross-sectional study conducted in the Department of General Surgery, Hamdard University Hospital Karachi, Pakistan for a period of six months from Oct 2020 to April 2021. The patients undergoing ventral hernia repair were included. Injection tranexamic acid 1gm intravenous twice a day for 1st post-operative day and then capsule Tranexamic acid 500mg per oral three times a day for two consecutive days was given and drain output was measured for 3 days. A total of 63 patients with ventral hernia were included, mean age of patients was 41.476 (±SD= 8.693). There were 41 male patients (65.1%) and 22(34.9%) females. The mean drain output on first day, second and third day was 115.047+14.678 ml/day, 91.919+9.947 ml/day, 66.914+7.070 ml/day and 273.254+29.165 ml/day respectively. The results showed overall reduction in postoperative drain output after oral and intravenous tranexamic acid for 72 hours. However further large scale randomized controlled trials are recommended for confirmation of these findings.

Robotic repair of moderate-sized midline ventral hernias reduced complications, readmissions, and length of hospitalization compared to open techniques.

To compare outcomes of robotic and open repair for uncomplicated, moderate-sized, midline ventral hernias. From 2017 to 2021, patient characteristics and 30day outcomes for all ventral hernias at our center were prospectively collected. We studied hernias potentially suitable for robotic repair: elective, midline, 3-10cm rectus separation, no prior mesh, and no need for concomitant procedure. Robotic or open repair was performed by surgeon or patient preference. The primary outcome was any complication using Clavien-Dindo scoring. Secondary outcomes were operative time, length-of-stay, and readmissions. Regression identified predictors of complications. Of 648 hernias repaired, 70 robotic and 52 open repairs met inclusion criteria. The groups had similar patient demographics, co-morbidities, and hernia size, except that there were more immunosuppressed patients in the open group (11 versus 5 patients, p = 0.031). Complications occurred after 7 (13%) open repairs versus 2 (3%) robotic repairs, p = 0.036. Surgical site infection occurred after four open repairs but no robotic repair, p = 0.004. Length-of-stay averaged almost 3days longer after open repair (4.3 ± 2.7days versus 1.5 ± 1.4days, p = 0.031). Readmission occurred after 6 (12%) oppen repairs but only 1 (1%) robotic repair. A long-term survey (61% response rate after mean follow-up of 2.8years) showed that the HerQLes QOL score was better after robotic repair (46 ± 15 versus 40 ± 17, = 0.049). In regression models, only open technique predicted complications. Robotic techniques were associated with fewer complications, shorter hospitalization, fewer infections, and fewer readmissions compared to open techniques. Open surgical technique was the only predictor of complications.

Comparison between intraperitoneal onlay mesh repair with closure of fascial defect (IPOM plus) and intraperitoneal onlay mesh repair (IPOM) for ventral hernias

Aim. To evaluate the intraperitoneal onlay mesh repair with closure of fascial defect (IPOM plus) versus intraperitoneal onlay mesh (IPOM) for ventral hernias (VHs). Materials and methods. A total of 89 patients with VHs with a defect between 3–12 cm who underwent a surgery from 2018 to 2023 years were enrolled in this study. All of them were randomly assigned to two groups. Group 1 included 45 patients after intraperitoneal onlay mesh repair with closure of fascial defect (IPOM plus), Group 2 – 44 patients after intraperitoneal onlay mesh (IPOM). The distribution of patients by age, sex, body mass index (BMI), hernia type (primary VH, incisional hernia), American Society of Anesthesiologists (ASA) score was studied. Results. The differences in sex, mean age, patient distribution based on hernia type, BMI, ASA score and hernia orifice size were not statistically significant between the two groups. Therefore, both groups were comparable. The operative time in minutes was 73.17 ± 7.43 in Group 1 and 70.93 ± 8.84 in Group 2 (not statistically significant). The pain score 12 hours after surgery was 5.24 ± 0.60 in Group 1 comparing to 5.02 ± 0.45 in Group 2 (not statistically significant). The pain score 8 days after surgery was 2.88 ± 0.31 in Group 1 comparing to 2.75 ± 0.43 in Group 2 (not statistically significant). There was no significant difference concerning the incidence of early complications between the two groups. 41 (91.11 %) patients of Group 1 and 40 (90.9 %) patients of Group 2 were examined during a 22-month follow-up period. No complications were noted. Conclusions. Laparoscopic ventral hernia repair provides satisfactory results in terms of safety and efficacy. Thus, IPOM plus repair is safe, feasible and offers possible advantages over the standard IPOM technique as reported in the literature. Poor outcomes described in the literature are probably related to independent variables such as mesh and suture types as well as closure technique.

A comparison of patient-reported outcomes in patients undergoing abdominal wall repair with either synthetic or biosynthetic mesh: a pilot study.

Repair of midline ventral incisional hernias (VIHR) requires mesh reinforcement. Mesh types can be categorised into synthetic, biosynthetic, or biological. There is a lack of evidence to support one type of mesh over another. The aim of this pilot study was to compare mesh sensation in patients having undergone elective open repair with synthetic or biosynthetic mesh. Four years of prospectively collected data were retrospectively reviewed on 40 patients who had undergone VIHR, using either biosynthetic or synthetic mesh placed in the retromuscular plane. The decision on type of mesh used was governed by patient characteristics. Patients were invited to complete the Carolinas Comfort Scale (CCS) questionnaire, the higher the score indicating a poorer quality of life. The maximum length of follow-up was 36months. Twenty patients received permanent synthetic and 20 biosynthetic mesh. There was no clinical evidence of hernia recurrence in either group in the short to medium term. Overall, 97% (39/40) patients reported an average of either no or mild symptoms (mean CCS score 17.9 of 115). Patients with a biosynthetic repair had a significant lower CCS at ≥ 18months (p < 0.05). After VIHR, patients have low CCS scores, indicating good quality of life outcomes, in the short to medium term irrespective of the mesh used. However, biosynthetic mesh had lower CCS scores in the medium term. This may help surgeons and patients make better informed decisions about which mesh to use in their individual circumstances.

Can surgeons accurately identify mesh type when interpreting computed tomography scans after ventral hernia repair?

Recurrent ventral hernia repair can be challenging due to scarred tissue planes and the increasing complexity of disease related to multiple recurrences. Given the challenges of acquiring complete and accurate prior operative reports, surgeons often rely on computed tomography (CT) scans to obtain information and plan for re-operation. Still, the contribution of CT scans and the ability of surgeons to interpret them is controversial. Previously, we examined the ability of surgeons to determine prior operative techniques based on CT scans. Here, we assessed the accuracy of expert abdominal wall reconstruction (AWR) surgeons in identifying the type of prior mesh using CT imaging. A total of 22 highly experienced AWR surgeons were asked to evaluate 21 CT scans of patients who had undergone open ventral hernia repair with bilateral transversus abdominis release utilizing mesh. The surgeons were required to identify the mesh type from a multiple-choice selection. Additionally, negative controls (patients without a history of prior laparotomy) and positive controls (patients with laparotomy but no ventral hernia repair) were incorporated. The accuracy of the surgeons and interrater reliability was calculated. The accuracy rate of the surgeons in correctly identifying the mesh type was 46%, with heavy-weight synthetic mesh (HWSM) being identified only 35.4% of the time, Strattice mesh and medium-weight synthetic mesh (MWSM) were identified at 46.3%, and 51.8%, respectively. The interrater reliability analysis found a moderate level of agreement 0.428 (95% CI 0.356-0.503), and the repeatability measure was poor-0.053 (95% CI 0-0.119); this indicates that surgeons cannot reliably replicate the identification process. Surgeons' ability to accurately identify the type of previous mesh using CT scans is poor. This study underscores the importance of documenting the type of mesh used in the operative report and the need for standardized operative notes to improve the accuracy and consistency of documentation.

Year-Over-Year Ventral Hernia Recurrence Rates and Risk Factors

Recurrence is one of the most challenging adverse events after ventral hernia repair as it impacts quality of life, utilization of resources, and subsequent need for re-repair. Rates of recurrence range from 30% to 80% after ventral hernia repair. To determine the contemporary ventral hernia recurrence rate over time in patients with previous hernia repair and to determine risk factors associated with recurrence. This retrospective, population-based study used the Abdominal Core Health Quality Collaborative registry to evaluate year-over-year recurrence rates in patients with prior ventral hernia repair between January 2012 and August 2022. Patients who underwent at least 1 prior ventral hernia repair were included and categorized into 2 groups based on mesh or no-mesh use. There were 43 960 eligible patients; after exclusion criteria (patients with concurrent inguinal hernias as the primary diagnosis, nonstandard hernia procedure categories, American Society of Anesthesiologists class unassigned, or no follow-up), 29 834 patients were analyzed in the mesh group and 5599 in the no-mesh group. Ventral hernia recurrence rates. Risk factors analyzed include age, body mass index, sex, race, insurance type, medical comorbidities, American Society of Anesthesiologists class, smoking, indication for surgery, concomitant procedure, hernia procedure type, myofascial release, fascial closure, fixation type, number of prior repairs, hernia width, hernia length, mesh width, mesh length, operative approach, prior mesh placement, prior mesh infection, mesh location, mesh type, postoperative surgical site occurrence, postoperative surgical site infection, postoperative seroma, use of drains, and reoperation. Among 29 834 patients with mesh, the mean (SD) age was 57.17 (13.36) years, and 14 331 participants (48.0%) were female. Among 5599 patients without mesh, the mean (SD) age was 51.9 (15.31) years, and 2458 participants (43.9%) were female. When comparing year-over-year hernia recurrence rates in patients with and without prior mesh repair, respectively, the Kaplan Meier analysis showed a recurrence rate of 201 cumulative events with 13 872 at risk (2.8%) vs 104 cumulative events with 1707 at risk (4.0%) at 6 months; 411 cumulative events with 4732 at risk (8.0%) vs 184 cumulative events with 427 at risk (32.6%) at 1 year; 640 cumulative events with 1518 at risk (19.7%) vs 243 cumulative events with 146 at risk (52.4%) at 2 years; 731 cumulative events with 670 at risk (29.3%) vs 258 cumulative events with 73 at risk (61.4%) at 3 years; 777 cumulative events with 337 at risk (38.5%) vs 267 cumulative events with 29 at risk (71.2%) at 4 years; and 798 cumulative events with 171 at risk (44.9%) vs 269 cumulative events with 19 at risk (73.7%) at 5 years. Higher body mass index; immunosuppressants; incisional and parastomal hernias; a robotic approach; greater hernia width; use of a biologic or resorbable synthetic mesh; and complications, such as surgical site infections and reoperation, were associated with higher odds of hernia recurrence. Conversely, greater mesh width, myofascial release, and fascial closure had lower odds of recurrence. Hernia type was the most important variable associated with recurrence. In this study, the 5-year recurrence rate after ventral hernia repair was greater than 40% and 70% in patients with and without mesh, respectively. Rates of ventral hernia recurrence increased over time, underscoring the importance of close, long-term follow up in this population.

Outcome of primary ventral hernia repair with monofilament polyester composite ventral patch in a community-based hospital

Background: Ventral hernia repair (VHR) is one of the common surgical procedures carried out in general surgery. This study assessed the post operative outcomes in patients with primary ventral hernia undergoing repair using monofilament polyester composite ventral patch Parietex™ Covidien (PCO-VP). Methods: A prospective single proportion observational study of 54 patients undergoing open VHR for primary ventral hernia with the PCO-VP in a community-based hospital was carried out. The patients were followed up for a period of one year from day of surgery. Primary outcome was recurrence, and secondary outcomes were reoperations and complications including seroma, hematomas, abdominal wall abscess, wound infections, and mesh infections. Results: Our sample size of (n=54) included 35 (65%) females and 19 (35%) males with a mean hernia defect diameter of 3.5±0.4 cm. 83% (45) underwent elective surgery (EL) and 17% (9) underwent emergency surgery with a mean operative time of 98.5 minutes, 11% (n=6) patients needed alteration of the technique and 20% (n=11) patients needed mesh repositioning, 12 adverse events were noted during the hospital stay. No mesh infections, early recurrences, readmissions or revision surgeries were noted. Patients had a average Carolina comfort scale score of 4/115 noted at the end of study. Conclusions: The use of PCO-VP to repair primary ventral hernia yielded nearly nil early recurrence rate, low postoperative complications and high satisfaction ratings, PCO-VP repair is a highly effective method for small and moderate size ventral hernias in both elective and emergency setting.

Sequential surgeries following transversus abdominis release for abdominal wall reconstruction: Insights from a single-center analysis

IntroductionAbdominal surgery following transversus abdominis release (TAR) procedure commonly involves incisions through the previously implanted mesh, potentially creating vulnerabilities for hernia recurrence. Despite the popularity of the TAR procedure, current literature regarding post-AWR surgeries is limited. This study aims to reveal the incidence and outcomes of post-TAR non-hernia-related abdominal surgeries of any kind. MethodsAdult patients who underwent non-hernia-related abdominal surgery following ventral hernia repair with concurrent TAR procedure and permanent synthetic mesh in the Cleveland Clinic Center for Abdominal Core Health between January 2014 and January 2022 were queried from a prospectively collected database in the Abdominal Core Health Quality Collaborative. We evaluated 30-day wound morbidity, perioperative complications, and long-term hernia recurrence. ResultsA total of 1137 patients who underwent TAR procedure were identified, with 53 patients (4.7%) undergoing subsequent non-hernia-related abdominal surgery post-TAR. Small bowel obstruction was the primary indication for reoperation (22.6%), and bowel resection was the most frequent procedure (24.5%). 49.1% of the patients required urgent or emergent surgery, with the majority (70%) having open procedures. Fascia closure was achieved by absorbable sutures in 50.9%, and of the open cases, fascia closure was achieved by running sutures technique in 35.8%. 20.8% experienced SSO, the SSOPI rate was 11.3%, and 26.4% required more than a single reoperation. A total of 88.7% were available for extended follow-up, spanning 17–30 months, resulting in a 36.1% recurrent hernia diagnosis rate. ConclusionsAbdominal surgery following TAR surgery is associated with significant comorbidities and significantly impacts hernia recurrence rates. Our study findings underscore the significance of making all efforts to minimize reoperations after TAR procedure and offers suggestions on managing the abdominal wall of these complex cases.

Weight reduction among females undergoing laparoscopic ventral hernia repair: The role of Calcium and Vitamin D3.

To evaluate the role of Vitamin-D and calcium supplementation on preoperative weight reduction in obese women before laparoscopic ventral hernia repair. This double-blind clinical trial was conducted at the affiliated health centers of King Faisal University, Al-Ahsa, Saudi Arabia from January 2021 to December 2021. It included forty-five obese women aged 24-56 years, with body mass index (BMI) of 34.0-48.0kg/m2. They were randomly allocated into two groups; the Group-A (N=22) included obese women who received supplementation of 5000IU cholecalciferol (Vitamin-D3), and 1000mg calcium daily for 12 months, while the Group-B (N=23) received no treatment. Measurement of change in weight and BMI and comparison of their pre-operative weight reduction, laparoscopic operative time, and length of hospital stay was done. There were no differences in patients' biographic data between the two groups. During the study, Vitamin-D level in the patients increased and there was a significant positive association with weight loss. In group-A, the mean weight loss was 11.8±3.5 kg. At the end of first year, their BMI decreased from 36.1±1.6kg/m2 at baseline to 29.7±2.6 kg/m2, whereas in-group-B, the mean weight loss was 6.8±3.1 kg and their BMI decreased from 36.9±2.69kg/m2 at baseline to 32.7±0.93kg/m2. The operation time and the length of hospital stay were shorter in group-A (107 vs.128.min) and (3 vs. 5 days) respectively as compared to Group-B. Vitamin-D and calcium supplementation contributes to a remarkable weight reduction of preoperative obese female patients, which in turn is associated with significantly better outcome of laparoscopic repair of ventral hernia.

Factors Associated With Respiratory Failure After Open Ventral Hernia Repair: An Evaluation of the NSQIP Database.

An analysis of ACS-NSQIP open ventral hernia repair (OVHR) data (2017-2019) was performed. Respiratory failure (RF) occurred in 643 patients (1%) and not in 63,213 (99%) (nRF). Respiratory failure patients were older (63.7 vs 57years, P < .001) and more comorbid: insulin-dependent diabetes (14.7% vs 5.8%, P < .001), COPD (19.4% vs 5.2%, P < .001), BMI (36.0 vs 32.8, P < .001), and current tobacco use (24.9% vs 17.6%, P < .001). Respiratory failure patients had greater ASA scores (ASA 3: 63.3% vs 47.8%, P < .001), bowel resection (8.2% vs 1.3%, P < .001), component separation (20.1% vs 9.0%, P < .001), operative times (178.4 vs 98.8minutes, P < .001), complications (deep wound infections 3.6% vs 1.0%, organ space infections 13.2% vs 1.0%, wound dehiscence 3.1% vs 0.6%, acute renal failure 11.7% vs 0.1%), and hospital stay (13.7 vs 2.3 days), with fewer home discharges (44.3% vs 96.4%) (all P < .001). Respiratory failure patients had higher mortality compared to nRF (20.2% vs 0.1%, P < .001). Respiratory failure after OVHR is rare but correlates closely with significant wound, systemic, and social complications. Preoperative management of risk factors would be appropriate in high-risk patients.

A randomized controlled trial on the effectiveness of laparoscopic-guided transversus abdominis plane block in patients undergoing laparoscopic IPOM plus.

Ventral hernia repairs, particularly laparoscopic ventral hernia repair (LVHR), have become common procedures among general surgeons worldwide. Despite the benefits of LVHR, acute postoperative pain remains a significant concern. Transversus abdominis plane (TAP) blocks have been employed to alleviate postoperative pain in various laparoscopic procedures. This study aimed to assess the effectiveness of laparoscopic-guided TAP block in laparoscopic IPOM plus and its impact on postoperative pain and analgesic requirements. A randomized controlled trial was conducted at a tertiary care center in India involving 72 patients undergoing laparoscopic IPOM plus. Patients were randomized into two groups: Group I received laparoscopic-guided TAP block, while Group II received standard general anesthesia without TAP block. Pain scores were assessed at 6, 12, and 24h postoperatively using the numerical rating scale. Postoperative analgesic requirements were also recorded. Group I demonstrated significantly lower pain scores at 6 and 24h postoperatively compared to Group II. The need for additional analgesics was significantly lower in Group I (13.8%) compared to Group II (72.2%). There were no significant differences in age, BMI, duration of surgery, or other demographic characteristics between the two groups. The findings of this randomized controlled trial demonstrate the effectiveness of laparoscopic-guided TAP blocks in reducing postoperative pain and analgesic requirements after laparoscopic IPOM plus.

Concomitant midline ventral and inguinal hernia repair: can we create an algorithmic approach?

International guidelines exist for surgical treatment of either ventral or inguinal hernias repair (VHR; IHR). However, approach for managing both of them remains unestablished and is further complicated by newly developed surgical techniques and modalities (namely, robotic). This highlights the need for a tailored, algorithmic strategy to streamline surgical management. An algorithm was developed by the directors of the NYU Langone Abdominal Core Health program of which four treatment groups were described: Group 1: open VHR and either laparoscopic or robotic IHR; Group 2: robotic transabdominal pre-peritoneal (TAPP) approach for both VHR and IHR; Group 3: robotic retro-muscular VHR and IHR; and Group 4: open repair for both. Demographics, comorbidities, operative characteristics, and surgical outcomes from November 2021 to July 2023 were retrospectively compared. Ninety-two patients were included with a median age of 64years, 90% (n = 83) were white, 85% (n = 78) were male, median BMI was 27kg/m2, and 73% (n = 67) were ASA class II. Distribution of groups was: 48% (n = 44) in 1A, 8% (n = 7) in 1B, 8% (n = 7) in 2A, 3% (n = 3) in 2B, 23% (n = 21) in 3A, 8% (n = 7) in 3B, and 3% (n = 3) in 4. Ventral hernia size, OR time, and postoperative length of stay varied across groups. Postoperative outcomes at 30days including emergency consults, readmissions, and complications, showed no differences across groups. Access without guidance to new minimally invasive surgical approaches can be a challenge for the general surgeon. We propose an algorithm for decision-making based on our experience of incorporating robotic surgery, when available, for repair of concomitant VHR and IHR with consistent favorable outcomes within a small sample of patients.
