This report describes the surgical anatomy and successful removal of the internal gonads in a 6-year-old male pseudohermaphrodite Friesian horse by standing laparoscopy. Gonads could not be identified by physical or ultrasonographic examination and bilateral standing flank laparoscopy revealed the presence of intra-abdominal gonads suspended from the dorsal aspect of the abdominal cavity by 10–15 cm long vascular pedicles. No evidence of female internal genitalia such as a uterus was found and bilateral gonadectomy was performed laparoscopically. Histological analysis of the excised gonads confirmed the diagnosis of male pseudohermaphroditism. Minor cosmetic surgery of the external genitalia to correct urinary misdirection was successfully performed 3 months after laparoscopic castration. Standing flank laparoscopic examination was excellent for identification and surgical removal of internal genitalia. Standing flank laparoscopy should be considered for inspection and removal of internal genitalia in intersex horses. 相似文献

目的：探讨腹腔镜下输卵管切除术对卵巢功能的近期影响。方法：将60例拟行输卵管切除术的异位妊娠患者随机分为3组（n=20）．手术方式分别采用腹腔镜单极电凝．腹腔镜双极电凝和开腹手术。术后1月、3月检测血清E2、P、T、FSH和LH水平，并与20例健康志愿者的激素水平相比较，观察患者术后月经恢复情况。结果：3组病人手术后卵巢激素水平与健康志愿者无显著差异，各组之间亦无显著差异，术后月经恢复情况各组之间也无明显差异。结论：与开腹手术一样．腹腔镜输卵管切除术对卵巢功能无明显影响。 相似文献

Objective To evaluate standing, percutaneous, ultrasound-guided, transthoracic liver biopsy in mares, and transabdominal, laparoscopically-guided, liver biopsy under general anaesthesia in foals, as techniques for obtaining tissue for assessment of copper status. The techniques were evaluated with respect to ease of use and effect on the animal.
Procedure Twenty of 24 Thoroughbred mares and 21 of their foals were biopsied. The animals were part of a larger study of the effect of copper supplementation on copper status and the prevalence of developmental orthopaedic disease. Livers were also collected from unrelated horses and sampled to investigate the variability in the distribution of copper in liver tissue.
Result The biopsy technique caused no lasting effect on the mares, but there was an increased risk of viscus penetration associated with taking multiple biopsy cores. The use of ultrasonography to scan the target area for the liver identified four cases that were not appropriate candidates for liver biopsy, because of large intestine being located in the biopsy area. In the foals there were no serious postoperative adverse effects, nor was there any evidence of problems caused by the procedure when the abdomen was examined post-mortem at 5 months of age. In livers collected to investigate the variability of copper concentration, copper appeared to be relatively evenly distributed through the liver.
Conclusion Standing, percutaneous, ultrasound-guided, transthoracic liver biopsy in mares, and transabdominal, laparoscopically-guided, liver biopsy under general anaesthesia in foals are convenient procedures for obtaining liver tissue for assessing copper status in horses. The use of ultrasound to identify liver tissue is recommended, especially in older mares. 相似文献

The surgical success of laparoscopic castration without orchidectomy results from avascular necrosis of the testes. However, failures and subsequent production of testosterone and stallion‐like behaviour have been previously identified. Laparoscopic castration without removal of the testes was performed in 32 horses with 2 normal descended scrotal testes between July 2006 and October 2012. The objectives of our study were to evaluate the success rate of laparoscopic castration without orchidectomy on descended testes in our population and assess complications and recovery time. Endocrine tests were performed after surgery and owners also asked to report on their horse's behaviour and ability to resume exercise. Castration was deemed successful if endocrine test results were in accordance with gelding values. Failed horses were castrated using a conventional technique and histology performed when possible. Basal testosterone levels decreased below 3 nmol/l after surgery in 30/32 cases. However, in 2 horses, stallion behaviour persisted and histological evaluation after inguinal castration showed residual viable tissue. Two horses maintained high testosterone levels after surgery associated with stallion‐like behaviour. Based on these results, 12.5% of horses (4/32 horses) failed to be considered a gelding based on either endocrine tests and/or histology. All horses, with one exception, were able to resume exercise less than a week after the procedure. Laparoscopic castration without orchidectomy appears to be a safe procedure. When assessing the success of laparoscopic castration, our total failure rate was 12.5% (4/32 horses) which is significantly higher than previously reported. 相似文献

Open surgical ovariohysterectomy in the mare provides limited visualisation and a long surgical incision. Laparoscopically‐assisted ovariohysterectomy has been performed by the authors in 3 mares with pyometra. This approach does seem to offset some of these disadvantages. 相似文献

目的总结腹腔镜全膀胱切除原位W形回肠代膀胱术的疗效。方法 11例浸润性膀胱癌患者行腹腔镜下全膀胱切除加原位W形回肠代膀胱术,记录手术时间、出血量、术后控尿功能恢复时间等。结果平均手术时间及出血量分别为7.5±0.8 h、610.3±12.5 m L,术后30~42 d均恢复控尿功能。术后21 d静脉尿路造影未见输尿管返流及梗阻。术后3个月尿动力检查显示尿流曲线呈持续型8例,间歇型3例。结论腹腔镜膀胱全切除原位W形回肠代膀胱术安全可行,控尿效果良好。 相似文献
