To evaluate in a pilot study an alternative technique using theloscopic surgery in the management of proximal teat stenoses of dairy cows.
The study included three lactating dairy cows (mean age 3.5 years) with a stenotic fibrous lesion in the proximal region of a teat. The lesions were suspected to be of traumatic origin and the diagnoses were confirmed by ultrasonography. For surgery, the cows were sedated and the base of the teat anaesthetized. The resectoscope was introduced through an incision in the teat cistern. The surgical area was continuously irrigated with saline solution and the stenotic lesions electroresected. Haemorrhage was controlled whenever possible by electrocoagulation.
In two cows, the procedure was successful and resulted in normal milk flow. One of the two cows was slaughtered soon after the operation for reasons unrelated to udder health. The other cow could be milked normally at a follow-up examination 4 months later and on ultrasonography, there was no recurrence of the stenotic lesions. In both cows, there was no evidence of concurrent intramammary infection. In the third cow, the procedure had to be discontinued because of severe intraoperative haemorrhage.
Video-assisted theloscopic electroresection of fibrotic teats is a promising, novel and minimally invasive technique for the surgical correction of the glandular part of the cistern. It should be considered as an alternative to conventional surgical methods in valuable dairy cows.
在一项初步研究中评估使用乳头镜手术治疗奶牛乳头近端狭窄的替代技术。
该研究纳入了三头泌乳奶牛（平均年龄3.5岁），其乳头近端存在狭窄性纤维病变。怀疑这些病变为创伤性起源，通过超声检查确诊。手术时，奶牛被镇静，乳头基部进行麻醉。经乳头池切口插入电切镜。手术区域用生理盐水持续冲洗，狭窄病变进行电切。尽可能通过电凝控制出血。
两头奶牛手术成功，乳汁流量恢复正常。其中一头奶牛术后不久因与乳房健康无关的原因被屠宰。另一头奶牛在4个月后的随访检查中能够正常挤奶，超声检查显示狭窄病变未复发。两头奶牛均无并发乳腺内感染的迹象。第三头奶牛因术中严重出血，手术不得不中止。
视频辅助乳头镜下纤维乳头电切术是一种有前景的、新颖的且微创的技术，用于手术矫正乳头池的腺性部分。对于有价值的奶牛，应将其视为传统手术方法的替代方案。
