P059: INFECTIONS ASSOCIATED WITH ABDOMINAL WALL REPAIRS: IS IT FEASIBLE TO KEEP THE MESH?

Background: treatment of surgical site infection (SSI) associated with prosthetic repair of the abdominal wall is very difficult given the lack of systematized therapeutic guidelines. The need to remove the prosthesis exposes the patient to reoperation and the risk of hernia recurrence, which increases costs and affects social and working life. The poor response to treatments could be linked to the administration of antibiotics for insufficient time.

Objective: to analyze the results of drainage and washing of the wound with prolonged antibiotic therapy (6 to 8 weeks).

Design: observational, prospective, longitudinal study.

Material and Methods: 9 patients with SSI following prosthetic parietal repairs treated with drainage and periodic washing and prolonged antibiotic therapy. Clinical response and bacteriological studies, number of procedures necessary to control the infection and length of hospital stay were evaluated.

Results: infection was controlled in 7 cases. The prosthesis had to be removed in 1 of them due to "malloma" and in 2 due to hernia recurrence. The cultures of secretions and meshes removed were negative in 7 patients. Twelve procedures (drains, punctures, debridements) were performed to treat the infection (mean: 1.33); mean of hospitalization: 3.44 days. (ambulatory management in 2 cases); mean of follow-up: 68.77 months.

Discussion: the drainage of the collections associated with prolonged antibiotic therapy and periodic washes was effective in 7 of nine patients and the mesh could be preserved in 4 patients. In 3 cases in which the mesh was removed due to “malloma” or recurrence of eventration, the cultures were negative.
