Application of polypropylene mesh on bilateral perineal hernia: A case study

Wound breakdown and infection were the most common postoperative complications in dogs af¬ter correction of perineal deformation not pre¬senting the polypropylene mesh, with the range of 6.4% to 45% (Burrow k Haney, 1973: ()r- sher, 1986). The application of polypropylene mesh was able to increase the risk of infection (Brown et al. 1985). Polypropylene mesh had the structure of nonabsorbable with polypropy¬lene monofilament. This structure was believed to prevent bacteria from being ambushed wit hin the fibres, which made this mesh different from oth¬ers to become infection (Fox et al., 1988; Trostle k Rosin. 1994). According to Kelly k Behrman (2002), in human, the clean-contaminated and contaminated operation could be performed with prosthetic mesh in the would-related morbidity and mortality. Nevertheless, fistula formation and mesh expulsion happened after months to years later (Falagas k Kasiakou, 2005). During the treatment, prophylactics antibiotics were used and cleaning of the perineal region with chlorhexidine 2% owing to the high inci¬dence of contamination of faeces and from the shelter. It was indicated that there was an in¬crease in the rate of postoperative infection in dogs that passed the clean surgical procedures ami received prophylactic antibiotics compared with others receiving without antibiotics (Usher k Gannon, 1959). Cleaning around the surgical wound could lead to inhibit the wound healing. Recurrence was also observed as the most pop¬ular complication of perineal hernia correction. Two critical factors that played a prominent role in recurrence, which was the status of perineal tis¬sues and the degree of atrophy of muscular pelvic diaphragm (Lee et al., 2012). Hernia recurrence in this study was depended on the observation of swelling perineal integument and the presence of clinical such as tenesmus. It was difficult that re¬currence was accurately determined if no related to clinical signs were noted after the swelling of the perineum. However, there was no appearance of recurrence in this case 8 months ago.
