Zhang, S. X., Wang, H. B., Zhang, H., Liu, H. F., Zhou, Z. F., Zhang, J. T. and Gao, L. 2014. Pilot laparoscopic ileal cannulation in pigs. Can. J. Anim. Sci. 94: 371–377. Pilot laparoscopic ileal cannulation was performed in eight anesthetized pigs (40.5±1.9 kg) positioned in dorsal recumbency using three portals in the abdomen. The T-shaped ileal cannulation site was located 15 cm anterior to the ileocecal valve on the antimesenteric section of the ileum. A transabdominal suspension suture was placed approximately 3 cm caudal to the ileal cannulation site. A purse-string suture was placed first around the insertion site, and a stab incision was made in the middle of the purse-string suture. The T-shaped cannula was inserted into the ileal lumen through the stab incision, and the purse-string suture was tightened. The T-shaped ileal cannula was pulled out of the abdominal cavity through the exit wound located 3–5 cm lateral and 10–12 cm caudal to the right or left side of the umbilicus. The transabdominal suspension suture was then removed. The T-shaped cannula was secured to the skin with a finger-trap suture. Surgical time and complications were recorded. Repeat laparoscopy was performed 35 d later. No major intraoperative or postoperative complications were encountered. The ileal contents were collected easily. On repeat laparoscopy, firm adhesion between the ileum and the abdominal wall was observed in all pigs, and there was no evidence of digesta leakage or consequential peritonitis.
