Laparoscopically assisted resection of umbilical structures in foals.

A technique for laparoscopically assisted resection of umbilical structures in foals was developed. Eleven foals ranging from 8 to 42 days old underwent this procedure. Results of bacteriologic culture of umbilical structures were positive in 7 foals. Mean duration of anesthesia was 99 minutes, of which the initial 20 to 25 minutes were typically devoted to positioning and preparation of the foal for surgery. Major complications did not develop in any foal. Minor complications, such as slippage of the endoscopic ligating clip or laceration of the bladder during dissection, were dealt with successfully during the procedure. Potential benefits of use of laparoscopy (i.e., decreased postoperative morbidity, smaller incisions, and increased intraoperative access to structures) must be carefully weighed against the risks of increased duration of anesthesia. However, anesthetic-related complications were not observed in any foal.
