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

INTRODUCTION: Abdominal 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. METHODS: Adult 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. RESULTS: A 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. CONCLUSIONS: Abdominal 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.

Long-term mesh-related complications from minimally invasive intraperitoneal onlay mesh for small to medium-sized ventral hernias.

INTRODUCTION: Intraperitoneal onlay mesh (IPOM) placement for small to medium-sized hernias has garnered negative attention due to perceived long-term risk of mesh-related complications. However, sparse data exists supporting such claims after minimally invasive (MIS) IPOM repairs and most is hindered by the lack of long-term follow-up. We sought to report long-term outcomes and mesh-related complications of MIS IPOM ventral hernia repairs. METHODS AND PROCEDURES: Adult patients who underwent MIS IPOM ventral hernia repair at our institution were identified in the Abdominal Core Health Quality Collaborative database from October 2013 to October 2020. Outcomes included hernia recurrence and mesh-related complications or reoperations up to 6 years postoperatively. RESULTS: A total of 325 patients were identified. The majority (97.2%) of cases were elective, non-recurrent (74.5%), and CDC class I (99.4%). Mean hernia width was 4.16 ± 3.86 cm. Median follow-up was 3.6 (IQR 2.8-5) years. Surgeon-entered or patient-reported follow-up was available for 253 (77.8%) patients at 3 years or greater postoperatively. One patient experienced an early small bowel obstruction and was reoperated on within 30 days. Two-hundred forty-five radiographic examinations were available up to 6 years postoperatively. Twenty-seven patients had hernia recurrence on radiographic examination up to 6 years postoperatively. During long-term follow-up, two mesh-related complications required reoperations: mesh removed for chronic pain and mesh removal at the time of colon surgery for perforated cancer. Sixteen additional patients required reoperation within 6 years for the following reasons: hernia recurrence (n = 5), unrelated intraabdominal pathology (n = 9), obstructed port site hernia (n = 1), and adhesive bowel obstruction unrelated to the prosthesis (n = 1). The rate of reoperation due to intraperitoneal mesh complications was 0.62% (2/325) with up to 6 year follow-up. CONCLUSION: Intraperitoneal mesh for repair of small to medium-sized hernias has an extremely low rate of long-term mesh-related complications. It remains a safe and durable option for hernia surgeons.

Quadratus lumborum block versus transversus abdominis plane block for inguinal hernia repair: A systematic review and meta-analysis with trial sequential analysis.

INTRODUCTION: Postoperative pain management is crucial for patient recovery with Quadratus Lumborum Block (QLB) and Transversus Abdominis Plane Block (TAPB) emerging as potential techniques. We aimed to compare the analgesic efficacy of QLB and TAPB in patients undergoing inguinal hernia repair. METHODS: We performed a systematic review of Cochrane, EMBASE, and MEDLINE databases to identify randomized controlled trials comparing QLB and TAPB in patients undergoing inguinal hernia repair. Outcomes included postoperative pain and opioid consumption. Statistical analysis was performed using RevMan 5.4. The review protocol was registered at PROSPERO (CRD42023445513). RESULTS: We included five RCTs encompassing 255 patients. QLB was associated with a significant decrease in postoperative pain (MD -0.45; 95% CI -0.75 to -0.14; and p = 0.004; I2  = 94%). However, we found no difference in 24-h opioid consumption between QLB and TAPB groups. CONCLUSION: QLB may offer superior pain reduction. However, its effect on opioid consumption remains unclear.

Evaluating the impact of lifting mandatory smoking cessation prior to elective abdominal wall reconstruction. A single-center experience.

INTRODUCTION: Many studies identify active smoking as a significant risk factor for postoperative wound and mesh complications in patients undergoing abdominal wall reconstruction surgery. However, our group conducted an analysis using data from the ACHQC database, which revealed similar rates of surgical site infection (SSI) and surgical site occurrence requiring procedural intervention (SSOPI) between active smokers and non-smokers As a result, the Cl eveland Clinic Center for Abdominal Core Health instituted a policy change where active smokers were no longer subject to surgical delay. Our study aims to evaluate the impact of active smoking on the outcomes of these patients. METHODS: We identified active smoking patients who had undergone open, elective, clean ventral hernia repair (VHR) with transversus abdominis release (TAR) and permanent synthetic mesh at Cleveland Clinic Foundation. Propensity matching was performed to create a 1:3 ratio of "current-smokers" and "never-smokers" and compared wound complications and all 30-day morbidity between the two groups. RESULTS: 106 current-smokers and 304 never-smokers were matched. Demographics were similar between the two groups after matching, with the exception of chronic obstructive pulmonary disease (COPD) (22.1% vs. 13.4%, p â€‹< â€‹.001) and body mass index (BMI) (31.1 vs. 32.6, p â€‹= â€‹.02). Rates of SSI (12.2% vs. 6.9%, p â€‹= â€‹.13), SSO (21.7% vs. 13.2%, p â€‹= â€‹.052), SSOPI (11.3% vs. 6.3%, p â€‹= â€‹.13), and reoperation (1.9% vs. 3.9%, p â€‹= â€‹.53) were not significantly different between active smokers and never-smokers correspondingly. One case (0.3%) of partial mesh excision was observed in the never-smokers group (p â€‹= â€‹1). The current-smokers group exhibited a significantly higher incidence of pneumonia compared to the never-smokers group (5.7% vs. 0.7%, p â€‹= â€‹.005). CONCLUSION: Our study revealed that operating on active smokers did result in a slight increase in wound morbidity, although it did not reach statistical significance. Additionally, pulmonary complications were higher in the smoking group. Notably, we did not see any mesh infections in the smoking group during early follow up. We believe that this data is important for shared decision making on patients that are actively smoking contemplating elective hernia repair.

Revisiting femoral hernia diagnosis rates by patient sex in inguinal hernia repairs.

INTRODUCTION: Guidelines recommend MIS repairs for females with inguinal hernias, despite limited evidence. We investigated rates of femoral hernias intraoperatively noted during MIS and Lichtenstein repairs in females. METHODS: ACHQC was queried for adult females undergoing inguinal hernia repair between January 2014-November 2022. Outcomes included identified femoral hernia and size, hernia recurrence, quality of life, and sex-based recurrence. RESULTS: 1357 and 316 females underwent MIS and Lichtenstein inguinal repair respectively. Femoral hernias were identified more frequently in MIS than open repairs (27%vs12%; (p â€‹< â€‹0.001). Most femoral hernias in MIS (61%) and Lichtenstein repairs (62%) were <1.5 â€‹cm(p â€‹< â€‹0.001). Identification rates of femoral hernias >3 â€‹cm were 1% overall(p â€‹= â€‹0.09). Surgeon and patient-reported recurrences were similar between approaches at 1-5-years for females(p â€‹> â€‹0.05 for all) and similar between sexes(p â€‹> â€‹0.05). CONCLUSION: Most incidental femoral hernias are small and both repair approaches demonstrated similar outcomes. The recommendation for MIS inguinal hernia repairs in females is potentially overstated.

Epidural analgesia and post-operative ileus after incisional hernia repair with transversus abdominis release: Results of a 5-year quality improvement initiative.

INTRODUCTION: The optimal pain management strategy after open ventral hernia repair (VHR) with transversus abdominus release (TAR) is unknown. Opioids are known to have an inhibitory effect on the GI tract and cause postoperative ileus. Epidural analgesia is associated with lower postoperative ileus rates but may contribute to other postoperative complications. A propensity-matched retrospective review published by our group in 2018 found that epidural analgesia was associated with an increased length of stay and any postoperative complication after VHR. Epidural analgesia was therefore abandoned by our group following this publication. We aimed to determine if discontinuation of epidural analgesia affected ileus rates after open VHR. METHODS: Patients who underwent open VHR with TAR from August 2014 to January 2022 â€‹at Cleveland Clinic Foundation with at least 30-day follow-up were retrospectively identified using the Abdominal Core Health Quality Collaborative registry. Patients with and without epidural analgesia were compared. The primary outcome was post-operative ileus. Additional outcomes included length of stay, deep venous thrombosis (DVT), pneumonia, wound complications and pain requiring intervention. RESULTS: A total of 2570 patients were included: 420 had an epidural, 2150 did not. Preoperative patient and hernia characteristics were similar between both groups. Mean hernia width was 15.5 â€‹cm in the epidural group and 16.1 â€‹cm in the no epidural group. In the epidural group, ileus was seen in 9 of 420 (2.15%) of patients which was significantly less than in the no epidural group, 400 of 2150 (18.6%), p=>0.001. On multivariate analysis, epidurals were predictive of lower risk of ileus (OR 0.04, 95%CI 0.01-0.17, p â€‹= â€‹0.001) and pain requiring intervention (OR 0.02, 95%CI 0.00-0.71, p â€‹= â€‹0.02). Epidural analgesia was not associated with increased DVT rates, pneumonia, length of stay, SSI, or SSOPI. DISCUSSION: Discontinuation of epidural analgesia was associated with a 9-fold increase in ileus rates after VHR with TAR. Epidurals may play an important role in limiting postoperative opioid use and therefore reducing risk of ileus. Other postoperative complications including pneumonia and venous thrombosis were not impacted by epidurals. Further prospective studies are needed to further define a ventral hernia patient population who will benefit from epidural analgesia.

Ventral Hernia Repair: Does Mesh Position Matter?

Mesh positioning is a commonly discussed detail in ventral hernia repair and is often cited as a major contributor to the outcome of the operation. However, there is a paucity of data that establishes one plane as superior to others. In this article, we will provide an overview of all potential planes to place prosthetic material and review the relevant literature supporting each option and the complications associated with accessing each anatomic plane.

Distressed community index as a predictor of presentation and postoperative outcomes in ventral hernia repair.

BACKGROUND: We evaluated the impact of socioeconomic status on presentation, management, and outcomes of ventral hernias. METHODS: The Abdominal Core Health Quality Collaborative was queried for adult patients undergoing ventral hernia repair. Socioeconomic quintiles were assigned using the Distressed Community Index (DCI): prosperous (0-20), comfortable (21-40), mid-tier (41-60), at-risk (61-80), and distressed (81-100). Outcomes included presenting symptoms, urgency, operative details, 30-day outcomes, and one-year hernia recurrence rates. Multivariable regression evaluated 30-day wound complications. RESULTS: 39,494 subjects were identified; 32,471 had zip codes (82.2%).Urgent presentation (3.6% vs. 2.3%) and contaminated cases (0.83% vs. 2.06%) were more common in the distressed group compared to the prosperous group (p < 0.001). Higher DCI correlated with readmission (distressed: 4.7% vs prosperous: 2.9%,p < 0.001) and reoperation (distressed 1.8% vs prosperous: 0.92%,p < 0.001). Wound complications were independently associated with increasing DCI (p < 0.05). Clinical recurrence rates were similar at one-year (distressed: 10.4% vs prosperous: 8.6%, p = 0.54). CONCLUSIONS: Inequity exists in presentation and perioperative outcomes for ventral hernia repair and efforts should be focused on increasing access to elective surgery and improving postoperative wound care.

Anterior reconstruction of the esophageal hiatus: a novel approach for the repair of large diaphragmatic hernias.

Introduction: Paraesophageal hernias (PEH) often require surgical repair. The standard approach, primary posterior hiatal repair, has been associated with a high recurrence rate. Over the past few years, we have developed a new approach for repairing these hernias, which we believe restores the original anatomy and physiology of the esophageal hiatus. Our technique includes anterior crural reconstruction with routine anterior mesh reinforcement and fundoplication. Objective: To determine the safety and the clinical success of anterior crural reconstruction with routine mesh reinforcement. Material and methods: Data were collected retrospectively on 178 consecutive patients who had a laparoscopic repair of a symptomatic primary or recurrent PEH between 2011 and 2021 using the above technique. The primary outcome was clinical success, and the secondary outcome was 30 days of major complications and patient satisfaction. This was assessed by imaging tests, gastroscopies, and clinical follow-up. Results: Mean follow-up was 65 (SD 37.1) months. No intraoperative or 30 days postoperative mortality or major complications were recorded. Recurrence rate requiring a re-operation was 8.4% (15/178). Radiological and gastroenterological evidence of minor type 1 recurrence was 8.9%. Conclusion: This novel technique is safe with satisfactory long-term results. The outcome of our study will hopefully motivate future randomized control trials.
