Summary
Standing gasless laparoscopic cryptorchidectomy is effective for bulls weighing 100-180 kg. This minimally invasive technique aids in locating and removing intra-abdominal testes in young bulls.
Area of Science:
- Veterinary Surgery
- Minimally Invasive Techniques
- Bovine Reproduction
Background:
- Cryptorchidism is a common condition in bulls, requiring surgical intervention.
- Intra-abdominal testes present surgical challenges in bovine patients.
- Computed tomography (CT) aids in preoperative localization of testes.
Purpose of the Study:
- To evaluate the feasibility and efficacy of standing gasless laparoscopic cryptorchidectomy in bulls.
- To determine the optimal weight range for this surgical procedure.
Main Methods:
- Ten standing bulls (3-15 months old) underwent laparoscopic cryptorchidectomy without insufflation.
- Preoperative CT scans identified intra-abdominal testes.
- Fasting for at least 24 hours facilitated visualization.
Main Results:
- Successful laparoscopic cryptorchidectomy was performed in all bulls.
- Surgical duration varied based on animal weight, ranging from 0.6 to 4 hours.
- Procedure was most efficient in bulls weighing 98-187 kg.
Conclusions:
- Standing gasless laparoscopic cryptorchidectomy is a viable surgical option for bovine cryptorchidism.
- The procedure is most suitable for bulls weighing between 100 and 180 kg.
- Minimally invasive techniques offer advantages in bovine reproductive surgery.
