To assess the feasibility of a novel technique involving a vessel and tissue-sealing device (VTSD) for ovariectomy in chickens to evaluate the potential application of the procedure to other avian species.
20 domestic laying hens (), of which 10 were immature (< 4 months old) and 10 were adults (> 18 months old).
Ovariectomy was performed with a VTSD through a left lateral celiotomy. Birds were allowed to recover for 14 days after the procedure and then were euthanized for necropsy. A board-certified veterinary pathologist performed complete necropsies, with particular attention to identifying any remaining ovarian tissue.
All birds survived the procedure. For the mature and juvenile birds, the mean ± SD durations of anesthesia (interval from intubation to extubation) were 67.2 ± 7.6 minutes and 50.5 ± 5.1 minutes, respectively, and mean durations of surgery were 45.3 ± 8.5 minutes and 31.6 ± 5.1 minutes, respectively. Three birds had severe hemorrhage during ovariectomy. At necropsy, ovarian tissue was present grossly in 2 mature birds and histologically in 6 additional birds (2 mature and 4 juvenile birds), indicating incomplete excision in 8 (40%) birds.
Results indicated that the evaluated VTSD can be used to successfully perform ovariectomies in both juvenile and mature chickens, although the procedure was associated with major hemorrhage and incomplete excision of ovarian tissue in some cases. Use of this VTSD for ovariectomy in birds of other species, particularly birds with reproductive tract disease, should be investigated.
评估一种涉及血管和组织密封装置（VTSD）的新型技术在鸡卵巢切除术的可行性，以评估该程序在其他禽类中的潜在应用。
20 只家养蛋鸡（），其中 10 只为未成熟（<4 个月），10 只为成年（>18 个月）。
通过左侧腹腔切开术用 VTSD 进行卵巢切除术。手术后，鸡允许恢复 14 天，然后安乐死进行剖检。一名经过委员会认证的兽医病理学家进行了全面的剖检，特别注意识别任何残留的卵巢组织。
所有鸟类都在手术中存活下来。对于成熟和幼年鸟类，麻醉（从插管到拔管的时间间隔）的平均±SD 持续时间分别为 67.2±7.6 分钟和 50.5±5.1 分钟，手术的平均持续时间分别为 45.3±8.5 分钟和 31.6±5.1 分钟。三只鸟在卵巢切除术中出现严重出血。在剖检时，2 只成熟鸟类的卵巢组织大体可见，6 只额外鸟类（2 只成熟和 4 只幼年鸟类）的卵巢组织组织学可见，表明 8 只（40%）鸟类的卵巢组织切除不完全。
结果表明，评估的 VTSD 可成功用于对幼年和成年鸡进行卵巢切除术，尽管该程序在某些情况下与严重出血和卵巢组织切除不完全有关。应研究这种 VTSD 在其他物种鸟类（特别是生殖道疾病鸟类）中的卵巢切除术的应用。
