Biofilms and effective porosity of hernia mesh: are they silent assassins?

ConclusionsWe discuss the two concepts of effective porosity and biofilm and propose potential measures to reduce mesh-related complications. This includes choosing mesh with superior mesh construct and technical nuances in implanting mesh to improve effective porosity. Furthermore, measures to reduce bacterial biofilm and its consequences are suggested.

Abstract Polypropylene (PP) meshes are the most widely used as hernioplasty prostheses. As far as hernia repair is concerned, bacterial contamination and tissue adhesion would be the clinical issues. Moreover, an optimal mesh should assist the healing process of hernia defect and avoid undesired prosthesis displacements. In this present study, the commercial hernia mesh was modified to solve the mentioned problems. Accordingly, a new bi-functional PP mesh with anti-adhesion and antibacterial properties on the front and adhesion properties (reduce undesired displacements) on the backside was prepared. The backside ...

ConclusionClosure of direct inguinal hernia defects during laparoscopic mesh repair has been shown to reduce the incidence of early hernia recurrence in our retrospective study but future randomized controlled trials with large numbers would enable us to draw more robust conclusions and perhaps change the way we perform laparoscopic inguinal hernia repair.

ConclusionsLaparo-endoscopic inguinal hernia mesh repair has a significant impact on performing a radical prostatectomy and PLND. Surgeons should postpone the inguinal hernia repair of patients in the workup for a radical prostatectomy, with the preferable option of performing the radical prostatectomy and inguinal hernia repair in the same procedure. Alternatively, a Lichtenstein repair can be performed.

ConclusionThis analysis suggested that a minor subset of PROMs improved in patients undergoing large-sized incisional and medium-sized parastomal hernia repair. High-quality studies are imperative in this extremely often conducted surgical procedure.Trial registrationThe review was registered at PROSPERO (CRD42018096671,

ConclusionsThe current study shows a favorable response to reinforced biologics, which were associated with an initial inflammatory response, resolving by later time points, followed by active remodeling, and the formation of new morphologically functional collagen.

AbstractBackgroundIncisional hernia repair requires detailed anatomic knowledge. Regarding median subxiphoidal hernias, the proper preparation of the fatty triangle is challenging. To foster proficiency-based training, a cost-efficient model for open median retromuscular mesh repair resembling the human body was developed, including the main anatomical structures related to the procedure. The aim is to create and validate a high-fidelity model on open retromuscular mesh repair suitable for"training before doing".Materials and methodsDifferent types of fabrics for imitation of connective tissue and 2-component sil...

CONCLUSIONS: Early-onset hernia mesh infection is mostly caused by St.aureus through exogenous contamination, whereas its late-onset counterpart might be a result of hematogenous or contact spread of intestinal flora. PMID: 31690215 [PubMed - as supplied by publisher]
