Follow-up of complex hernia repair with intraoperative fascial traction.

Abstract

<h4>Background</h4>Different techniques for complex abdominal wall repair are utilised including intraoperative fascial traction (IFT) as the latest development. Despite increasing case numbers for IFT across Europe, long-term data especially on recurrence rates are not available yet.<h4>Methods</h4>Follow-up data from five different German hernia centers between 12/2019 and 9/2023 were assessed. All patients received Rives-Stoppa repair (RSR) and IFT intraoperatively with an additional transverse abdominis muscle release (TAR) in some cases. 30-day postoperative outcome data were retrospectively collected Standardized follow-up was performed after a minimum of 3 months including clinical examination and standardized ultrasound.<h4>Results</h4>A total of 100 patients were included in the study. The mean age was 60.7 ± 14.3 years; the mean BMI was 31.3 ± 7.3 kg/m² with a mean follow-up of 19.7 ± 10.7 months. The mean defect width was 15.8 ± 5.2 cm. In 94% of the patients complete fascial closure was achieved; in 28% an additional TAR procedure was necessary During follow-up, 2 recurrences were found. The surgical site occurrence (SSO) rate was 33% including mainly seromas (54.5%) and surgical site infections (SSI) of 9% Comparing the groups of IFT + TAR and IFT + RSR a significantly higher incidence of SSO was found in the TAR group (50% vs. 26.4%, p<0.01).<h4>Conclusions</h4>This study, which is the first long-term follow-up, shows very promising results of the innovative IFT technique in terms of closure rate, wound morbidity, and recurrence rate.
