Early and Late Outcome After Suprasonic Excision of Infected Mesh Implants After Hernioplasty

The purpose of this research is to analyze early and postponed complications of the new method to eliminate mesh implants during full-grown infection process.

The Republican clinical hospital (Russia) was the location to carry out a post-hoc analysis of 149 cases on surgical removal of infected mesh implants for ventral hernias of different localization in the period 2000 to 2017. The control group were 78 patients who underwent meshes removal with traditional surgical instruments. The study group included 71 patients, who underwent our method of supra-sonic excision of the implants.

The duration of surgery in the group of patients subjected to supra-sonic excision of the implants was significantly lower (84.3 min vs. 141.5 min) than in the group of traditional surgical techniques. Complications of early postoperative period was most often registered in the control group: foreign bodies (92.8% vs. 7.2%), infection (81.8% vs. 18.2%) and bleeding (87.5% vs. 12.5%). In the long term the recurrence of hernias in the control group were detected 1.8 times more frequently for ventral hernias than in the group of supra-sonic excision of the implants.

Thus, supra-sonic excision of the implant prevents damage to viable tissues of the abdominal wall during the allocation of the implant and provides a good bactericidal effect, which promotes normal tissue regeneration and prevents possible recurrence of the herniation.
