Surgical treatment of chronic penile prolapse in Vietnamese pot-bellied pigs: 5 cases (2016-2017).

OBJECTIVE

To describe the surgical treatment and short- and long-term outcome of young pot-bellied pigs with penile prolapse.

STUDY DESIGN

Short case series.

ANIMALS

Five young castrated Vietnamese pot-bellied pigs.

METHODS

Five Vietnamese pot-bellied pigs presented with penile prolapse of several weeks duration. No other abnormalities were found at physical examination. Under general anesthesia, phallopexy with or without combined urethropexy was performed successfully in all cases.

RESULTS

All pigs were discharged from the hospital. One pig required a second urethropexy the day after the initial surgery to improve positioning of the penis in the prepuce. Long-term outcome was available in 4 cases. Penile prolapse resolved in the 4 cases available for follow-up, and the owners were satisfied with the cosmetic outcome of the procedure.

CONCLUSION

Penile prolapse was successfully corrected in 5 pot-bellied pigs by using 2 different phallopexy techniques. The procedure was combined with urethropexy in 3 pigs. Long-term outcome was excellent in the 4 cases available for follow-up.

CLINICAL IMPACT

This is the first report describing the use of phallopexy with or without urethropexy for successful treatment of penile prolapse in young pot-bellied pigs. Two different phallopexy techniques were effectively used in this report. The etiology of penile prolapse in pot-bellied pigs remains unknown.
