Abstract

A 4.5-yr-old multiparous female eastern bongo (Tragelaphus eurycerus isaaci) presented with a prolapsed vagina 4 mo after dystocia and vaginal extraction of a large calf. The prolapse was corrected via manual reduction and vulvoplasty (Caslick operation). A melengesterol acetate contraceptive implant was placed and the bongo was asymptomatic for 6 yr until vaginal prolapse recurrence. The vaginal prolapse recurred four times over a 2-yr span and was managed with repeat Caslick procedures and several epidural injections using 95% grain alcohol. Complications secondary to long-term progestin implant usage, acquired urovagina, as well as perineal atony from the alcohol epidurals are believed to have contributed to prolapse recurrence. Ovariohysterectomy and vaginoplasty ultimately were elected and were curative. According to a survey conducted in response to this case, obstetrical issues and female reproductive tract problems appear to occur sporadically in captive bongo but are not uncommon.
