Surgical Treatment of Recurrent Rectal Prolapse in an Adult Female Black‑crested Mangabey (Lophocebus aterrimus) by Colopexy

摘要

A 13-y-old, multiparous female black-crested mangabey (Lophocebus aterrimus) underwent surgical treatment for chronically recurring rectal prolapse by laparotomy and subsequent colopexy. Initially, a laparoscopic approach was attempted but was converted to an open approach after intraabdominal adhesions were noted. The colopexy was performed through a ventral midline incision, with no complications intraoperatively or postoperatively. The predisposing factors responsible for the development of this condition likely were related to pelvic floor weakness due to multiple past pregnancies. Transport-associated stressors likely contributed to the acute worsening of this patient's condition. Rectal prolapse is a common condition in laboratory-housed NHP. This case report describes an effective surgical treatment for recurring or otherwise nonreducible rectal prolapse in these species.
