Objective:To demonstrate that the monofilamentous, macroporose, heavy, polypropylene mesh can be re-sterilized with 100% ethylene oxide without undergoing changes in its physical characteristics and can be used safely.
Setting:High Specialty Medical Unit.
Design:Prospective, longitudinal comparative study.
Statistical analysis:Descriptive statistics and Fisher’s test.
Material and methods:The study included 60 patients, older than 15 years and of either gender, operated under epidural anesthesia by the same surgeon from November 2000 to November 2004. Patients were randomly divided in two groups: Group A, new mesh (n = 30). Group B, re-sterilized mesh (n = 30). Analyzed variables were: age, gender, site of the hernia, aggregated diseases, hernia classification, surgical time, hospital stay, early and late complications, and recurrences as well as the use of drainages and/or antibiotics. We used the Gilbert/Rutkow classification. Follow-up at 7-14 and 30 days, 6-12-24-36, 48 months.
Results:Sixty three inguinal repairs in 60 patients (3 bilateral), handled ambulatory, 54 men (85.7%) and 9 women (14.3%), age range 19 to 90 years. All were primary hernias. No drainages or antibiotics were used. No recurrences or infections occurred. Complications consisted of seroma in one case and disesthesia in another. There were no cases of disabling inguinodynia. No differences existed between groups.
Conclusions:The polypropylene mesh can be re-sterilized with 100% ethylene oxide without altering its physical properties and does not increase the incidence of infections or recurrences.
