Prevention and Treatment of Infection Wound Complications at Prosthetic Hernia Repair

Abstract

Purpose – development of practical recommendations for prevention and treatment of infectious wound complications at prosthetic hernioplasty, based on the peculiarities of blood supply of the front abdominal wall. Materials and methods. 851 surgeries of prosthetic hernioplasty were made in Propaedeutic Surgery Clinic of Samara State Medical University throughout 2010–2013. The most of infectious complications developed after tension-free hernioplasty of big postoperative ventral hernias, with size of hernia orifice of 10 cm and more (W3–W4, Chevrel–Rath, 1999). 118 hernia repairs have been done for such hernias. These surgeries are peculiar by wide mobilization of cutaneous fat flaps and implant contact with the subcutaneous tissue. The imaging of blood vessels in median masses of the anterior abdominal wall was carried out using anatomic material. Results. Very interesting results were obtained with respect to peculiarities of blood supply to the skin and subcutaneous tissues of anterior abdominal wall, upon pumping of zinc sulfide and lead acetate to the epigastric arteries. The infectious wound complications after prosthetic hernioplasty are mostly concerned with the ischemia of cutaneous and subcutaneous flaps, which wide mobilization causes considerable blood supply disturbance and cellular tissue hemorrhages. In cases of hernia orifices size of 10 cm and more, the occurrence rate of infectious wound complications was 13,6 %. Conclusions. In case of wide mobilization of cutaneous fat flaps, the excision of deep layers of subcutaneous cellular tissue is possible and the aspiration drainage is mandatory. The ischemic genesis of complications causes a possibility of restricted surgical activity. Even development of infectious complications does not prevent the implant survival.
