Introduction

Perineal hernia (PH) is one of the most common diseases in older intact male dogs, which are thought to contribute to progressive weakness and atrophy of pelvic diaphragm muscles. The incidence of recurrent rate is high within one year after surgical herniorrhaphy.

Objective

Furtherance of an alternative surgical technique of perineal herniorrhaphy, synthetic polyethylene was implied as a connecting line between ischium and transverse process of scrum. The successful rate was observed in post-operative complications in dogs.

Methods

Ten dogs presented to Kasetsart Veterinary Teaching Hospital for treatment of perineal hernia were signalment, clinical signs and diagnosed by rectal palpation/radiology/ultrasonography. The dogs weighed between 1.9 and 24 kg (10.5 ± 10 kg). All of them showed clinical signs of dyschezia with perineal swelling. Five (50%) dogs had bilateral and another five (50%) showed unilateral perineal hernia. Dogs underwent surgery with the procedure of double sacroischial slings between ischium and transverse process of sacrum before further suturing of pelvic diaphragm. Postoperative complications were monitored for 12 weeks.

Result

All dogs were well recovered with mild complications. The recurrence was developed in one (10%) dog within 48 days.

Conclusion

Sacroischial suture with synthetic polyethylene in perineal hernia dogs showed an accomplishment. This technique can be used in case of weakness of internal obturator muscle.

Figure 1 For perineal herniorrhaphy, double polyethylene sacroischial slings were performed by insertion of a leader line through pre-drilled holes on the ischium bone and the lateral inter-transverse process of sacrum (A. dorsoventral view, B. Lateral view).
