The aetiology of this disease involved in this process was poorly determined but associated with multi-factors which included gonadal hormone im- balance, rectal abnormalities, prostatic disease, and myopathy. Ad- ditionally, the prevalence of middle age and old dogs overwhelmed the young ones due to the change in livelihood and diet. Although there was a certain rate of success in treatment for perineal hernia, this disease had high proportions of recurrence and postoperative complications. This study was conducted at Sasaki Animal Hospital in Ho Chi Minh City to manage this disease by the synthetic mesh implant. A 10-year castrated male Pomeranian (5.2 kg) was referred to clinical examination because of a 4-month complaint of the return of a mass at the perineal area. The owner also reported constipation and hematuria with the presence of pus. Rectal palpation and ra- diography indicated that the bladder contained in the hernia sac. Ultrasound showed that the bladder contained a large clump of pus. Blood test and antimicrobial-resistant test were also performed by taking the blood and urine with a pus sample, respectively. The ill animals were treated for bacterial infection and then operated to relocate hernia by polypropylene mesh. After 14-day operation, the results were considered satisfactory, which the perineal area returned to normal without any complications. However, the recurrence of this non-infectious disease was reported to range from 10-46%. Therefore, the following health check was necessary to perform twice within a year. Cited as: Luong, D.

Introduction Perineal hernia was an acquired disorder caused by the inability of a weak pelvic di- aphragm to hold and support pelvic organs. Pelvic disfigurement was clear and occurred ei- ther on one or both sides of perineum. Depend- ing on the location of this disfigurement, it was divided into the internal herniation (ventral, in- guinal, umbilical and perineal herniation) and the external herniation including diaphragm her- nia (Mann et al., 1995; Head & Francis, 2002). Several techniques had been described to correct the perineal hernia. The first method to relocate the herniated organ was traditional herniorrha- phy. However, internal obturator muscle transpo- sition, over the traditional herniorrhaphy in de- creasing distortion of the external anal sphincter, was the most common methods due to its suc- cess rate (Orsher, 1986). Besides, gluteal muscle transposition, semitendinosus muscle transposi- tion, synthetic implant, and biomaterial were the additional techniques to augment internal obtu- rator muscle transposition.
