Evaluation of the clinical efficacy of TAR hernioplasty of the abdominal wall using endoprostheses with a nafion coating

The aim of the study was to improve the treatment results of patients after anterior non–tensioning hernioplasty using endoprostheses with a nafion coating.

Material and methods. A prospective, non-randomized study involved 120 people divided into 2 groups. The main group (n = 60) consisted of patients operated on using a polypropylene endoprosthesis with a nafion coating. The control group (n = 60) consisted of patients with classical hernioplasty. For subgroups A, the operation was performed using the “in-lay” method. Subgroups B (n = 30) — posterior separation hernioplasty. All patients were examined in the standard volume. The follow-up period was 6 months. The number, nature, and timing of purulent complications and infiltrates, as well as the volume of lymphorrhea, were recorded. The SPSS 17.0 software was used for statistical data processing.

Results. The use of nafion coating on endoprostheses used in hernia repair, regardless of their size, showed a statistically significant reduction in the number of complications. The use of modified endoprostheses in preperitoneal plastic surgery improves the results of its implementation, making them comparable to TAR plastic surgery. The use of a modified endoprosthesis in posterior separation hernioplasty significantly reduces the number of postoperative infiltrates and seromas in the surgical area compared with the use of a similar material in preperitoneal plastic surgery. There was no pathogenic microflora in the crops from the wound discharge in the main group.

Conclusion. The use of a polypropylene endoprosthesis with a nafion coating in performing various posterior abdominal wall surgeries in patients with postoperative ventral hernias leads to a statistically significant decrease in the frequency of postoperative lymphorrhea and purulent-inflammatory complications.
