Laparoscopic cryptorchidectomy and ovariectomy in standing horses using the EnSeal® tissue-sealing device.

The research study examined the use of a medical device called EnSeal® in laparoscopic cryptorchidectomy and ovariectomy surgeries on horses. The researchers found that the device was successful in sealing and cutting blood vessels and suspensory ligaments during minimally invasive surgery, which may have resulted in shorter operation times and faster recoveries for the horses.

Research Objectives and Methodology

• The researchers aimed to test the effectiveness of the EnSeal® device in laparoscopic cryptorchidectomy and ovariectomy surgeries in horses. These surgeries involve removing undescended testicles and ovaries, respectively.
• The study was conducted on a total of 12 horses – 8 underwent cryptorchidectomy and 4 underwent ovariectomy. These surgeries were all performed while the horses were standing and sedated, which is considered to pose less risk than general anesthesia.

Findings

• The usage of EnSeal® provided superior visualization of the surgical area, which in turn led to shorter operation times and faster recoveries. The EnSeal® device efficiently sealed and cut the blood vessels supplying the testes and ovaries, and the suspensory ligaments of the organs.
• This positive outcome was observed in all surgeries, indicating that the EnSeal® device was consistently successful in performing its intended function. The treated tissue areas were gradually separated from the intact tissue, becoming compacted, dehydrated, and homogenized. The lumen of the treated blood vessels was effectively occluded by the device.

Significance and Implications

• The successful use of EnSeal® in these types of surgery represents a promising development in veterinary surgery. The device’s ability to seal and cut blood vessels and ligaments during minimally invasive surgery could lead to improved outcomes for horses undergoing these procedures.
• As per the researchers’ knowledge, this study is the first of its kind, marking the inaugural use of EnSeal® for laparoscopic cryptorchidectomy and ovariectomy surgeries in horses.
