Reduction of perineal infection following abdominoperineal resection with the use of gentamicin-collagen fleece. rev. colomb. cir. [online]. 2017, vol.32, n.4, pp.277-282.

Background: Abdominal-perineal resection in patients with rectal cancer undergoing preoperative radiotherapy exhibit as a frequent complication the perineal infection of the operative site, manifested as cellulitis to perineal collections and wound dehiscence, which significantly increases hospitalization time. Reducing the incidence of operative site infection helps to diminish perioperative morbidity and mortality. The use of local antibiotics in the surgical wound has been reported in the literature as a protective factor with promising results to avoid this complication Methods: This is a case series report to study the outcome of patients undergoing abdominoperineal resection with the implantation of a gentamicin-collagen fleece in the perineal closure. Patients included were treated by the Department of Coloproctology of the Hospital Universitario San Ignacio (HUSI), Bogotá, Colombia. The main purpose of the study was to describe the institutional experience with the utilization of the gentamicin-collagen fleece to reduce the risk of surgical site infection. Results: Twelve patients were included. Surgical site infection incidence was 41% when the gentamicin-collagen fleece was used. Nine patients had received neoadyuvant therapy and three were taken to surgery without previous neoadyuvant therapy. Five patients developed surgical site infection, superficial surgical site infection was present in three and organ/space surgical site infection developed in two cases requiring surgical drainage. There was no evidence of adverse reactions with the use of the gentamicin-collagen fleece. Conclusions: The results show a positive effect of the gentamicin-collagen fleece in reducing the frequency of surgical site infection. Patients who received neoadyuvant therapy had a higher risk of surgical site infection. There is no need to modify the surgical technique and there is no increase in the procedures' morbidity with the use of the gentamicin-collagen fleece. Even though the results indicate a possible reduction in the surgical site infection incidence, further studies are required to obtain statistically significant conclusions.
