Laparoscopic salpingectomy in Papio hamadryas for birth control in captivity.

OBJECTIVE

To evaluate the feasibility of laparoscopic salpingectomy in baboons (Papio hamadryas). We hypothesized that laparoscopic salpingectomy could be performed in baboon species within a reasonable amount of surgical time, with minor complications occurring at low rates.

STUDY DESIGN

Case series and technique description.

ANIMALS

Sixteen baboons (n = 16).

METHODS

The surgical procedures were performed using the 3-port technique, with 5 mm instruments and a telescope placed at the umbilical and hypogastric regions. A salpinx dissection was performed, using a radiofrequency bipolar vessel sealing device, from the fimbriae to the uterine attachments. We evaluated the surgical duration, learning curve, and intraoperative and early postoperative complications.

RESULTS

Ten adult and 6 subadult baboons with a mean weight of 9.32 kg, a range of 4-14.2 kg, and a standard deviation (SD) of 3.09 kg were included in the study. The total duration of surgery was 28.75 min (range, 16-50 min; SD, 9.60 min). The installation phase was completed in a mean time of 7.68 min (range, 3-15 min; SD, 3.43 min), and the time to complete the salpingectomy of both salpinges was 9.68 min (range, 4-20 min; SD, 3.97 min). No complications were observed in the postoperative period.

CONCLUSION

Laparoscopic salpingectomy in Papio hamadryas was feasible, with an acceptable surgical time, low invasiveness, and only minor technical perioperative complications.

CLINICAL SIGNIFICANCE

Laparoscopic salpingectomy could be a viable and safe therapeutic option in nonhuman primate birth-control programs.
