Bottom Line: Surgical procedure was interrupted by intra-abdominal fat and testis size.It took 0.6 to 1.5 hr in 4 animals weighing 98 to 139 kg, 0.8 to 2.8 hr in 4 animals weighing 170 to 187 kg, and 3 and 4 hr in 2 animals weighing 244 and 300 kg to complete the cryptorchidectomy.In conclusion, standing gasless laparoscopic cryptorchidectomy seems to be most suitable for bulls weighing from 100 to 180 kg.

ABSTRACT
Laparoscopic cryptorchidectomy without insufflation was applied in 10 standing bulls aged 3 to 15 months. Nine bulls were preoperatively pointed out intra-abdominal testes by computed tomography. Preoperative fasting for a minimum of 24 hr provided laparoscopic visualization of intra-abdominal area from the kidney to the inguinal region. Surgical procedure was interrupted by intra-abdominal fat and testis size. It took 0.6 to 1.5 hr in 4 animals weighing 98 to 139 kg, 0.8 to 2.8 hr in 4 animals weighing 170 to 187 kg, and 3 and 4 hr in 2 animals weighing 244 and 300 kg to complete the cryptorchidectomy. In conclusion, standing gasless laparoscopic cryptorchidectomy seems to be most suitable for bulls weighing from 100 to 180 kg.

The laparoscope (①) and 2 forceps portals (②, ③) were established. Cryptorchidtestis is grasped with forceps (C). Image D and E showing laparoscopic procedure in abull with bilateral cryptorchidism. To approach the left cryptorchid testis via a portmade in the right flank, a small incision was made in the mesocolon (D). The camera wasinserted through the incision in the mesocolon to locate the left testis (E).

Mentions: Laparoscopic examination and surgery were performed using a TRICAM SL camera system and aXENON NOVA cold light fountain (KARL STORZ GmbH & Co. KG, Tuttlingen, Germany). After 24hr of fasting, the animals were restrained to a stall, shaved and locally anesthetized with 2%lidocaine (Xylocaine® injection 2%, AstraZeneca K.K., Osaka, Japan) SC and IM(20–30 ml/head) in the flank. In addition to local anesthesia, Cases 3, 5 and6 also received epidural anesthesia with 2% lidocaine (4 ml/head between thefirst and second lumbar vertebrae). Laparoscopy was performed via the right or left flankapproach. After the operative field was disinfected with chlorhexidine and 70% alcohol anddraped, a 2-cm incision was made through the skin, and blunt dissection was made through thesubcutaneous tissue and muscles to expose the peritoneum. The peritoneum was grasped with Peanforceps, and after incision of the peritoneum, nylon stay sutures were placed through the skinand the peritoneum. A trocar cannula (11 mm in diameter and 20 cm in length; KARL STORZ GmbH& Co. KG) was then inserted. The port site was determined based on the findings duringrectal palpation or based on the CT results. Through this port, a 0˚ laparoscope (10 mm indiameter and 65 cm in length; KARL STORZ GmbH & Co. KG) was inserted to examine theabdominal cavity. Then, a trocar cannula (11 mm in diameter and 15 cm in length; OlympusCorporation, Tokyo, Japan) was inserted as the second portal for forceps (Fig. 1A and 1BFig. 1.
