本研究的主要目的是评估腹腔镜卵巢切除术并开发针对站立牛的最佳手术技术。八头奶牛接受了腹腔镜卵巢切除术。在两头奶牛中，采用双侧胁腹入路，在六头奶牛中，通过左胁腹入路切除双侧卵巢。确保腹内足够的器械空间、最佳的内窥镜方向以及易于接近卵巢和子宫的一个重要先决条件是在手术前禁食至少 36 It。给奶牛注射甲苯噻嗪镇静剂，并用利多卡因浸润肝门部位。腹腔镜入口位于左侧腰椎旁窝的腹角，距髋结节约 10 cm 处。将器械通过距块茎基节腹侧约 20 厘米和 30 厘米的两个入口插入。腹部吹入二氧化碳后，抓住左侧卵巢，向卵巢系膜和输卵管系膜注射局麻药。使用双极烧灼横断卵巢系膜，并通过扩展的器械入口取出卵巢。以同样的方式切除右侧卵巢。用肌肉组织中的单间断可吸收缝合线和皮肤中的单间断不可吸收缝合线封闭切口。手术持续120-150分钟。通过左胁腹入路对站立的奶牛进行双侧腹腔镜卵巢切除术是可行的。该手术涉及特殊仪器，但具有微创性，并且可以实现卵巢和子宫的最佳可视化。 (c) 2005 Elsevier B.V. 保留所有权利。
The main objective of this study was to evaluate laparoscopic ovariectomy and to develop an optimal surgical technique for this procedure in standing cattle.Eight cows underwent laparoscopic ovariectomy. In two cows, a bilateral flank approach was used and in six cows, both ovaries were removed via a left flank approach.An important prerequisite for ensuring sufficient intrabdominal space for instrumentation, optimal endoscopic orientation and easy access to the ovaries and uterus was withholding feed for at least 36 It prior to surgery. The cows were sedated with xylazine and the portal sites infiltrated with lidocaine. The portal for the laparoscope was at the ventral angle of the left paralumbar fossa, approximately 10 cm cranioventrad to the tuber coxae. The instruments were inserted through two portals approximately 20cm and 30cm ventral to the tuber coxae. After abdominal insufflation with carbon dioxide, the left ovary was grasped and local anesthetic was injected into the mesovarium and mesosalpinx. The mesovarium was transected using bipolar cauterization and the ovary removed through an extended instrument portal. The right ovary was removed in the same way. The incisions were closed with single interrupted absorbable sutures in the musculature and single interrupted non-absorbable sutures in the skin. The procedure lasted 120-150 min.Bilateral laparoscopic ovariectomy via left flank approach in standing cows is feasible. This procedure involves special instrumentation, but is minimally invasive and allows optimal visualization of the ovaries and uterus. (c) 2005 Elsevier B.V. All rights reserved.
