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.
