The first experience with the Dextile anatomical mesh in laparoscopic inguinal hernia repair.

Background: The Dextile Anatomical mesh (Medtronic) is a polypropylene heavyweight mesh and has a 3D patented anatomical shape which adapts to the contours of the extra-peritoneal inguinal region without the need for fixation, potentially reducing the risk of hernia recurrence and chronic post-operative pain. This retrospective study will be the first study to assess the outcomes of the Dextile Anatomical mesh compared to another three-dimensional mesh, the 3DMax mesh (Bard).

Methods: Between 2019 and 2022, all patients who underwent an elective unilateral inguinal hernia repair were assessed. 416 patients in the Dextile Anatomical mesh group and 540 patients in the 3DMax mesh group were included. Outcomes were intra- and post-operative complications, inguinal hernia recurrence and chronic post-operative inguinal pain.

Results: No significant differences were found between the two groups regarding intra- and post-operative complications including wound infection, antibiotic use, hematoma, seroma, urinary retention and delayed wound healing. 1-year recurrence rate was comparable for the Dextile Anatomical mesh group and the 3DMax mesh group, respectively, 3.8% and 3.0%, P = 0.45. Chronic post-operative inguinal pain was similar for the Dextile Anatomical mesh (3.4%) and the 3DMax mesh (3.0%), P = 0.72.

Conclusion: This retrospective study comparing the relatively new Dextile Anatomical mesh (Medtronic) with the 3D Max mesh (Bard) in unilateral inguinal hernia repair showed that both meshes are safe and effective to use. There were no significant differences in intra-operative outcomes, recurrence rates and chronic post-operative inguinal pain.
