Abstract
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.

Vet Surg 2022; 51 Suppl 1:O69-O79.

Abstract
OBJECTIVE To develop, describe, and evaluate 2 surgical techniques for contraception of free-ranging female capybaras. STUDY DESIGN Prospective study. ANIMALS Cadaveric (n = 3) and free-ranging female capybaras (n = 21). METHODS Preliminary studies of surgical anatomy were performed on 3 capybara cadavers. Two different techniques for partial salpingectomy were evaluated in free-ranging female capybaras: bilateral minilaparotomy (LTG; n = 11) or bilateral laparoscopy (LCG; n = 10). Data concerning body weight, tubal ligation time, total surgical time, incision size, and intraoperative and postoperative complications were analyzed, as well as the clinical status and incisional healing 1 week postoperatively. RESULTS Body weight (P = .214), ligation time of the left uterine tube (P = .901), and total surgical time (P = .473) were similar between the experimental groups. The ligation time of the right uterine tube was shorter in the LCG group (P = .0463). In the LTG, no differences were observed between the sides regarding the incision size (P = .478). No major intraoperative or postoperative complications occurred in either group. One LCG procedure had to be converted to LTG due to technical issues. All skin incisions healed without complication. CONCLUSION Both procedures showed similar and satisfactory outcomes. CLINICAL SIGNIFICANCE The proposed techniques may be a suitable alternative to conventional laparotomy for contraception of female capybaras, especially under field conditions.

Tubectomy of Pregnant and Non-pregnant Female Balinese Macaques ( Macaca Fascicularis) With Post-operative Monitoring. Front Vet Sci 2021; 8:688656. [PMID: 34568470 PMCID: PMC8458650 DOI: 10.3389/fvets.2021.688656] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 08/09/2021] [Indexed: 11/24/2022] Open
Abstract
Worldwide, primates, and humans increasingly share habitats and often enter in conflict when primates thrive in human-dominated environments, calling for special management measures. Reproductive control is increasingly used to manage population growth but very few monitoring data are available. Therefore, the efficiency and implications of such programs require a careful examination. In the context of a contraception program in wild female long-tailed macaques in Ubud, Bali, conducted over four successive campaigns between 2017 and 2019, including 140 females (i.e., 41.9% of the reproductive females of the population in 2019), modifications of an endoscopic tubectomy procedure, a permanent sterilization method, clinical evaluation of this method, and the post-operative monitoring results of the neutered females after release are described. This surgical approach was applicable for pregnant females: 28.6% of the treated females were pregnant at the time of the surgery. The procedure used a single lateral port to reach and cauterize both oviducts in non-pregnant as well as in early to mid-term pregnant females. Pregnant females nearer to term required a second lateral port to access both oviducts masked by the size of the gravid uterus. Moreover, bipolar thermocauterization was utilized successfully without resection to realize the tubectomy. The average duration of the laparoscopic surgery was 14 min for non-pregnant females and 22 min for pregnant females. Animals were released 3 h 22 min in average following their capture. This short holding time, recommended for free-ranging primates, was made possible by the minimal invasiveness of the sterilization approach. A laparoscopic post-operative evaluation conducted on two patients during the following campaign confirmed that the oviducts were definitely disrupted and no longer patent. Moreover, no new pregnancies in sterilized females were recorded during the 3-year observation period. The survival rate of the treated females 6 months after sterilization was high (96.3%) with no major post-operative complications clinically recorded. Among females that were pregnant during surgery, 81.1% were confirmed to experience term delivery. This study demonstrates the safety and efficiency of endoscopic tubectomy, even for pregnant females, as a mean of wild macaques' population control.
