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.

Abstract Aims We report our experience with a cellular porcine dermal non-crosslinked biological mesh (EGIS®). We conducted a review of indications and outcomes of patients requiring the mesh for incisional hernia/complex abdominal wall reconstruction with component separation, parastomal hernia repairs and ELAPE. Patients were followed for a minimum of 6 and assessed for recurrence, seroma formation and chronic pain. Secondary outcome was the assessment of ease of use by the Surgeon – suturing and pliability. Method A retrospective case notes review of patients requiring biological mesh (EGIS®) from 2016 to present. A qualitative survey about ease of use of EGIS® for operations studied was sent to all Consultant Surgeons. Results EGIS® mesh was used in 38 patients: 23 Hernia repairs – 13 Incisional, 8 Parastomal, 2 Paraumbilical; 12 Pelvic floor repairs after ELAPE; and 3 abdominal wall reconstructions. Hernia recurrence occurred in 12 (32%), seroma 7 (18%) and chronic pain 7 (18%). The highest complications occurred in the incisional and parastomal hernia groups. Incisional hernia: recurrence in 5 (38%), seroma in 5 (38%) and chronic pain in 3 (23%). Parastomal hernia: recurrence in 3 (38%), chronic pain 2 (25%), seroma 1 (13%). Consultants scored the mesh 4.3 to 4.5 out of 10 for pliability, ease of use and suturing. Conclusion Biological mesh is used to reinforce hernia repairs in contaminated or potentially contaminated fields. Non-crosslinked meshes are preferred for their greater cellular infiltration from host tissue with improved integration. Our experience with this mesh shows a high complication rate and requires re-evaluation.

Introduction: Traumatic abdominal wall hernias (TAWHs) after blunt trauma, while rare, are typically associated with severe injuries, particularly those involved with the seatbelt triad of abdominal wall disruption. The aim of this study is to present a case series of patients with TAWHs that were managed at an early stage post injury with a biological mesh. Materials and Methods: Patients with TAWH undergoing complex abdominal wall reconstruction (CAWR) between 2017 and 2020 were identified from our institutional database. All patients underwent definitive reconstruction using advanced surgical techniques including a posterior component separation with biological mesh (STRATTICE™, Allergan, Inc., Dublin, Ireland) placed in a sublay fashion. Results: Seven patients underwent definitive TAWH repair during their index admission: the median age was 56 years (range 20–77) and the median Injury Severity Score (ISS) was 34 (29–50). The most common mechanism of injury was motor vehicle crash (MVC) at 86%, while the most common intra-abdominal concomitant injury was small bowel. Traumatic hernia location was on the right side of the abdominal wall in three patients, left in three patients, and bilaterally in one patient. There were no hernia recurrences or deaths in this small cohort. Conclusion: Traumatic abdominal wall disruption can be safely reconstructed using advanced surgical techniques with a biological mesh during the acute phase or same index hospitalization.
