Modified multilayer alloplasty of complicated inguinal hernias

Abstract

Aim. To enhance the treatment outcomes of complicated inguinal hernias (characterized by a high inguinal gap, a large hernia orifice, a weakened posterior wall of the inguinal canal, or recurrence) through the implementation of a developed technique involving multilayer alloplasty.

Materials and Methods. Within the overall cohort of 396 patients who underwent inguinal hernia surgeries between 2019 and 2023, the prevalence of complicated hernias was investigated. The main study group comprised 28 patients with complicated inguinal hernias who underwent surgery following the proposed method utilizing a two-layer prosthesis.

Results. Complicated inguinal hernias, necessitating additional reinforcement of the posterior wall of the inguinal canal, predominantly manifest in patients with a large hernia orifice size (W3 — 6.57 ± 1.25 %), a significant inguinal gap (13.13 ± 1.70 %), and a history of relapses (8.59 ± 1.41 %). An associated condition complicating hernioplasty and elevating the risk of recurrence (0.618) is obesity (61.76 ± 8.33 % in the recurrent hernia group). The application of the developed hernioplasty method shows no significant difference in terms of complication risk and subjective sensations compared to the Lichtenstein method. Notably, no hernia recurrences were observed with the utilization of the duplication plasty technique.

Conclusion. The suggested duplication design of the prosthesis proves effective in providing extensive reinforcement for the inguinal gap in cases of problematic hernias. It is easy to position and is associated with minimal discomfort, as reported by the subjective sensations of patients.
