A three-portal laparoscopic hysterectomy in a chimpanzee (Pan troglodytes) with a uterine manipulator and vessel sealing device

Objective: To report the treatment and outcome of a a captive chimpanzee (Pan troglodytes) undergoing 3-portal laparoscopic hysterectomy. Additionally, the technique used for successful urinary catheterization is described.

Animals: A 29-year-old female intact chimpanzee with uterine bleeding.

Study design: Clinical case report.

Methods: Uterine changes consistent with adenomyosis and/or endometriosis were noted on abdominal ultrasonographic and computed tomographic examinations. A urinary catheter was placed before a 3-portal laparoscopic hysterectomy with a uterine manipulator (VCare) and a vessel sealer (Ligasure). The uterus was submitted for histopathology.

Results: Preoperative urinary catheterization was achieved with several modifications and prevented bladder protrusion into the surgical field. Laparoscopy provided excellent visualization of the pelvic structures and VCare effectively maneuvered the uterus for a safe and efficient dissection. The use of the vessel sealer was effective, and bleeding was minimal. Anesthesia and surgery lasted 240 and 150 minutes, respectively. No complications were encountered. Histopathological changes of the uterus were consistent with adenomyosis and myometrial hyperplasia. The chimpanzee recovered uneventfully and returned to normal behavior with no recurrence of uterine bleeding 5 months after surgery.

Conclusion: The 3-portal laparoscopic technique reported here allowed hysterectomy without complication in this chimpanzee. Urinary catheterization was technically challenging but successful.
