A method of video-assisted thoracoscopic surgery for collection of thymic biopsies in rhesus monkeys (Macaca mulatta).
To support an infectious disease study, we developed a surgical procedure to collect serial thymic biopsies in rhesus monkeys (Macaca mulatta). In many instances in which thymic tissue is required from living animals, open surgical approaches (thoracotomies) are used, which result in greater postoperative pain and longer recovery periods than those associated with thoracoscopic procedures. Our intent was to develop a surgical procedure that allowed serial biopsy of the thymus with minimal surgical morbidity. We modified a previously published experimental method of thoracoscopic total thymectomy in the dog to collect thymic biopsies in M. mulatta. Of the 15 animals evaluated, 8 underwent two biopsy procedures separated by a 5- to 6-week interoperative interval. The other seven animals underwent a single biopsy procedure. Thymic tissue was collected successfully during all procedures, with an average surgical time of 15 min. No significant intra- or postoperative complications were noted, and the animals recoveries from the surgical procedures were uneventful. Minimally invasive thoracoscopic surgical techniques can be used successfully to collect thymic tissue from adult and juvenile rhesus monkeys with minimal surgical morbidity.
