Background: Mediumweight (40–60 g/m2) polypropylene (MWPP) mesh has been shown to be safe and effective in CDC class II–III retromuscular ventral hernia repairs (RMVHR). However, MWPP has the potential to fracture, and it is possible that heavyweight (> 75 g/m2) polypropylene mesh has similar outcomes in this context. However, there is limited data on HWPP mesh performance in clean-contaminated and contaminated scenarios. We aimed to compare HWPP to MWPP mesh in CDC class II–III wounds during open RMVHR. Methods: The Abdominal Core Health Quality Collaborative database was retrospectively queried for a cohort of patients who underwent open RMVHR with MWPP or HWPP mesh placed in CDC class II/III wounds from 2012 to 2023. Mesh types were compared using a 3:1 propensity score-matched analysis. Covariates for matching included CDC classification, BMI, diabetes, smoking within 1 year, hernia, and mesh width. Primary outcome of interest included wound complications. Secondary outcomes included reoperations and readmissions at 30 days. Results: A total of 1496 patients received MWPP or HWPP (1378 vs. 118, respectively) in contaminated RMVHR. After propensity score matching, 351 patients remained in the mediumweight and 117 in the heavyweight mesh group. There were no significant differences in surgical site infection (SSI) rates (13.4% vs. 14.5%, p = 0.877), including deep SSIs (0.3% vs. 0%, p = 1), surgical site occurrence rates (17.9% vs. 22.2%, p = 0.377), surgical site occurrence requiring procedural intervention (16% vs. 17.9%, p = 0.719), mesh removal (0.3% vs. 0%, p = 1), reoperations (4.6% vs. 2.6%, p = 0.428), or readmissions (12.3% vs. 9.4%, p = 0.504) at 30 days. Conclusion: HWPP mesh was not associated with increased wound morbidity, mesh excisions, reoperations, or readmissions in the early postoperative period compared with MWPP mesh in open RMVHR for CDC II/III cases. Longer follow-up will be necessary to determine if HWPP mesh may be a suitable alternative to MWPP mesh in contaminated scenarios. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Purpose: Although intraoperative music is purported to mitigate postoperative pain after some procedures, its application has never been explored in abdominal wall reconstruction (AWR). We sought to determine whether intraoperative music would decrease early postoperative pain following AWR.We conducted a placebo-controlled, patient-, surgeon-, and assessor-blinded, randomized controlled trial at a single center between June 2022 and July 2023 including 321 adult patients undergoing open AWR with retromuscular mesh. Patients received noise-canceling headphones and were randomized 1:1 to patient-selected music or silence after induction, stratified by preoperative chronic opioid use. All patients received multimodal pain control. The primary outcome was pain (NRS-11) at 24 ± 3 h. The primary outcome was analyzed by linear regression with pre-specified covariates (chronic opioid use, hernia width, operative time, myofascial release, anxiety disorder diagnosis, and preoperative STAI-6 score).178 patients were randomized to music, 164 of which were analyzed. 177 were randomized to silence, 157 of which were analyzed. At 24 ± 3 h postoperatively, there was no difference in the primary outcome of NRS-11 scores (5.18 ± 2.62 vs 5.27 ± 2.46, p = 0.75). After adjusting for prespecified covariates, the difference of NRS-11 scores at 24 ± 3 h between the music and silence groups remained insignificant (p = 0.83). There was no difference in NRS-11 or STAI-6 scores at 48 ± 3 and 72 ± 3 h, intraoperative sedation, or postoperative narcotic usage.For patients undergoing AWR, there was no benefit of intraoperative music over routine multimodal pain control for early postoperative pain reduction.ClinicalTrials.gov: NCT05374096.Methods: Although intraoperative music is purported to mitigate postoperative pain after some procedures, its application has never been explored in abdominal wall reconstruction (AWR).

Introduction: Fixation of mesh during minimally invasive inguinal hernia repair is thought to contribute to chronic post-herniorrhaphy groin pain (CGP). In contrast to permanent tacks, absorbable tacks are hypothesized to minimize the likelihood of CGP. This study aimed to compare the rates of CGP after laparoscopic inguinal hernia repair between absorbable versus permanent fixation at maximum follow-up. Methods: This is a post hoc analysis of a randomized controlled trial in patients undergoing laparoscopic inguinal hernia repair (NCT03835351). All patients were contacted at maximum follow-up after surgery to administer EuraHS quality of life (QoL) surveys. The pain and restriction of activity subdomains of the survey were utilized. The primary outcome was rate of CGP, as defined by a EuraHS QoL pain domain score ≥ 4 measured at ≥ 1 year postoperatively. The secondary outcomes were pain and restriction of activity domain scores and hernia recurrence at maximum follow-up. Results: A total of 338 patients were contacted at a mean follow-up of 28 ± 11 months. 181 patients received permanent tacks and 157 patients received absorbable tacks during their repair. At maximum follow-up, the rates of CGP (27 [15%] vs 28 [18%], P = 0.47), average pain scores (1.78 ± 4.38 vs 2.32 ± 5.40, P = 0.22), restriction of activity scores (1.39 ± 4.32 vs 2.48 ± 7.45, P = 0.18), and the number of patients who reported an inguinal bulge (18 [9.9%] vs 15 [9.5%], P = 0.9) were similar between patients with permanent versus absorbable tacks. On multivariable analysis, there was no significant difference in the odds of CGP between the two groups (OR 1.23, 95% CI [0.60, 2.50]). Conclusion: Mesh fixation with permanent tacks does not appear to increase the risk of CGP after laparoscopic inguinal hernia repair when compared to fixation with absorbable tacks. Prospective trials are needed to further evaluate this relationship. [ABSTRACT FROM AUTHOR]
