A modified salvage technique in surgical repair of perineal hernia in dogs using polypropylene mesh

Abstract

ABSTRACT:In 16 male dogs who suffered from perineal hernia, polypropylene mesh was used to close a defect in the pelvic diaphragm. Pelvic bone was drilled on the pelvic floor and mesh was sutured through holes by polypropylene suture. Strong pelvic diaphragm, good long-term results and time-sparing by this technique was achieved. Suture sinuses were developed in two dogs one month postoperatively. Objectives of this study were to describe a new alternative technique of perineal herniorraphy and postoperative possible complications. Weakness of internal obturator muscle flap is complication which can be observed during transposition of internal obturator muscle flap. This technique can be used when internal obturator muscle flap is weak like the operation of the first choice.

Perineal herniorrhaphy in a dog using a cone‐shaped polypropylene mesh implant

“…The most common postoperative complications in hernia repair using a mesh are seroma (8–22 per cent) (Zogbi 2011) and infection (up to 45 per cent) (Szabo and others 2007). However, no recurrence rate was found (Vnuk and others 2006). …”

“…The recurrence rate has been described from 29 per cent to 61 per cent in patients operated by standard perineal herniorrhaphy (Shaughnessy and Monnet 2015) and from 19 per cent to 45 per cent in those undergoing transposition of the internal obturator muscle. On the contrary, no recurrence rate was found in patients undergoing herniorrhaphy with the use of a polypropylene mesh (Vnuk and others 2006). …”

Perineal Hernia Repair Using an Autologous Tunica Vaginalis Communis in Nine Intact Male Dogs

“…The recurrence rates have been reported from zero to 18.75% after TIOM [11,19,24,27,28], and zero to 12.5% after the use of a polypropylene mesh [9,26,28]. Principally, a surgeon should avoid the technique using foreign material when one utilizing the patient's own tissue is possible [28].…”

“…Among the techniques attempted to avoid reherniation, transposition of the internal obturator muscle (TIOM) is the most reliable technique and considered now the conventional herniorrhaphy. The transposed muscle increases strength of the ventral perineum where most hernias occur [11,19,24,27,28]. The reports on the herniorrhaphy utilizing other patient's own tissues for closing the defect include transposition of the superficial gluteal muscle [22,29], semitendinosus muscle [8] and fascia lata [5].…”

“…The reports on the herniorrhaphy utilizing other patient's own tissues for closing the defect include transposition of the superficial gluteal muscle [22,29], semitendinosus muscle [8] and fascia lata [5]. The synthetic and biological materials that have been reported for PH repair in dogs are a polypropylene mesh [9,26,28] and porcine small intestinal submucosa [25].…”
