Abstract Aim Adhesions are fibrous bands of scar tissue that form following peritoneal injury, commonly intra-abdominal surgery, and are associated with serious morbidity such as small bowel obstruction and pain. Surgical meshes used for incisional hernia repair are associated with increased incidence and severity of adhesions. There is limited consensus on which mesh may induce the least adhesions following incisional hernia repair, and most previous data has come from experimental animal models. We aimed to evaluate existing primary research to investigate whether biological mesh limits adhesion formation compared to synthetic or biosynthetic mesh when used in patients for incisional hernia repair and also to assess whether there is correlation with existing animal model data. Material and Methods A systematic search was conducted on PubMed and EMBASE. The number of mesh-related adhesions, character of adhesions and adhesion-related complications were documented. Results were compared to previously published results from animal models. Results Thirty-two studies were included, 11 of which did not document whether the adhesions were mesh related. A total of 14,161 participants underwent incisional hernia repair, 8,526 of whom were included in follow-up analysis. Overall, 9.7% developed adhesions. Biological mesh induced a high rate of dense adhesions, whereas biosynthetic mesh induced loose, filmy adhesions suggested to cause fewer complications. These findings were similar to findings from experimental animal models. Conclusions Bio-synthetic mesh was superior in causing fewer and less dense adhesions. Further analysis of mesh-induced adhesion formation on a larger scale is required to fully understand the consequences of different mesh types.

AbstractThe introduction of biological or absorbable synthetic meshes has provided an alternative to conventional repair for incisional hernia. The ability to predict the development of complications after hernia surgery is important, as it guides surgical planning and patient management. This retrospective study assessed whether the postoperative C-reactive protein (CRP) level can predict complications after incisional hernia repair using biological mesh reinforcement. Patients who underwent incisional hernia repair surgery using biological meshes between February 2009 and February 2015 were screened for study inclusion. Patients included in the study were divided into two groups: those with and without postoperative complications. The two groups were analysed based on sex, surgical operation, length of intensive care unit stay (ICU), complications and mortality. Laboratory values, including white blood cell (WBC) count and CRP levels, were determined preoperatively and up to postoperative day (POD) 10. Postoperative complications requiring further management occurred in 32 of the 60 patients (53.3%). Among 47 patients, the mean CRP and WBC levels were 6.6 mg/L and 9.073 G/L in the group without complications vs. 141.0 mg/L, 16.704 G/L in the group with complications (p < 0.001). Patients with complications also had a longer ICU stay (10.1 vs. 0.6 days, p < 0.0001). A cut-off was 101 mg/L and offered 80.00% sensitivity (IC 61.43% to 92.29) and 95.24% specificity (76.18% to 99.88%) for postoperative complication. The rate of postoperative complications before POD10 was 95% in the group with CRP > 100 mg/L vs. 46% in the group with CRP < 100 mg/L (p = 0.000372). A high postoperative CRP level (> 100 mg/L) up to POD10 may serve as a predictor of postoperative complications in patients undergoing incisional hernia using biological meshes.

Abstract Aim Traditional anterior component separation during incisional hernia repair is associated with a high rate of postoperative wound morbidity. Because extensive subcutaneous dissection is avoided by endoscopic anterior component separation (eACS) or open transversus abdominis release (TAR), we hypothesized that these techniques did not increase the incidence of surgical site occurrence compared to incisional hernia repair without component separation. Material and Methods This was a retrospective cohort study of patients undergoing open, retro-rectus incisional hernia repair. Component separation during retro-rectus repair was performed using eACS or TAR. The primary outcome was 30-day incidence of postoperative surgical site occurrence. Secondary outcomes included length of stay, 30-day readmission, 30-day reoperation rate and 3-year recurrence rate. Results A total of 322 patients underwent retro-rectus repair, 168 (52%) of whom received either eACS or TAR. Addition of eACS or TAR was neither associated with surgical site occurrence, (odds ratio: 0.82, confidence interval: 0.40-1.68, P = 0.596) nor with hernia recurrence (hazard ratio 0.80, CI 0.27-2.40, P = 0.693). There was no significant difference between the groups regarding the frequencies of 30 day-readmission or 30-day reoperation. Conclusions The addition of eACS or TAR to a retro-rectus incisional hernia repair was not associated with increased wound morbidity or hernia recurrence.
