Objective. To give a clinical assessment and conduct a comparative analysis of the frequency of postoperative complications in patients with free and strangulated hernias of various localizations after tension-free hernioplasty using synthetic implants.Materials and methods. A retrospective analysis of 965 medical records of inpatient patients who underwent tension-free hernioplasty for hernias of various localizations in the period from 2018 to 2022 was carried out. The results of the study were processed using applied statistics using MS Excel and a software package for statistical analysis “Statistica v. 10.0”. Statistically significant differences were considered at p < 0.05.Results. The study revealed that in the postoperative period after tension-free hernioplasty in patients with strangulated hernias, the complication rate was 15.8%. At the same time, the frequency of complications was higher after “onlay” hernioplasty in patients with strangulated hernias than in patients with free hernias. The frequency of postoperative complications in patients with impaired postoperative ventral hernias is 8.3 times higher than in patients with free postoperative ventral hernias. In the postoperative period, complications such as seroma and infiltration of the postoperative wound were detected in 10.5 and 5.2% of cases in patients with strangulated hernias. The duration of inpatient treatment for patients with complications after hernioplasty is 2.6 times longer compared to patients without complications (p < 0,05).Conclusion. In the postoperative period, in patients with strangulated hernias, the incidence of complications was observed in 15.8% of cases, and in patients with free and irreducible hernias in 1.5% of cases. Clinically, such postoperative complications as seromas, infiltrates of the postoperative wound, ligature fistulas, scrotal hematoma, orchitis, abscess of the postoperative wound were identified.
