TPLO was associated with a significantly higher rate of infection-inflammation than the infection-inflammation rate after ECLS stabilization. The use of suture material other than staples for skin closure and postoperative oral administration of antimicrobials may be protective in minimizing infection-inflammation in dogs with rupture of the CCL that are treated via ECLS or TPLO.

High body weight and preoperative patellar tendon angle were significantly associated with complications following TTA in dogs. Subsequent meniscal tear was the most common reason for second surgery, suggesting that medial meniscal release of intact menisci should be considered when performing TTA in dogs.

Bilateral thyroidectomy was performed in 106 cats with hyperthyroidism by one of three techniques: original intracapsular, modified intracapsular, or modified extracapsular. Hypocalcemia was detected in the first 3 days after surgery in 11 (22%) of 50 cats treated by the intracapsular technique, 10 (33%) of 30 cats treated by the modified intracapsular technique, and 6 (23%) of 26 cats treated by the modified extracapsular technique. Hypocalcemia was classified as mild or severe. No signs of hypoparathyroidism developed in any of the 13 cats with mild hypocalcemia. Of the 14 cats with severe hypocalcemia, 8 had clinical signs of hypoparathyroidism before and during treatment with calcium and vitamin D, 3 were treated and no clinical signs developed, 2 were not treated but no clinical signs developed, and 1 was lost to follow-up. No cat required permanent calcium or vitamin D supplementation after surgery. Severe hypocalcemia and clinical signs of hypoparathyroidism occurred in 3 (6%) of the 50 cats treated by the intracapsular technique, 4 (13.3%) of the 30 cats treated by the modified intracapsular technique, and 1 (3.8%) of the 26 cats treated by the modified extracapsular technique. Twelve cats had recurrence of hyperthyroidism at a median time of 23 months. The intracapsular technique was used in 11 of these cats, and the modified extracapsular technique was used in 1. No clinical signs of hypothyroidism were detected in any of the cats. The modified intracapsular and modified extracapsular techniques of bilateral thyroidectomy are effective procedures for the treatment of feline hyperthyroidism.

Eleven cats in which subtotal colectomy with end-to-end jejunocolostomy was performed for the treatment of chronic obstipation secondary to pelvic fracture malunion were followed for at least 18 months. Seven cats had no recurrence of clinical signs and no longterm complications. In two cats, constipation was less severe and occurred less frequently; however, medical treatment was still required. In one cat, watery diarrhea gradually changed to semiformed feces of normal consistency by month 6; the cat was clinically normal at month 18. One cat had recurrence of constipation and was euthanatized after 2 years of medical treatment.

Results suggested that in cats, VBO for removal of inflammatory polyps or masses is unlikely to affect hearing as measured via air-conducted BAER. Most cats developed short-term Horner syndrome. Cats with deafness prior to surgery did not regain auditory function. Ventral bulla osteotomy to remove nasopharyngeal polyps or masses provided no functional advantage with regard to restoration of hearing, compared with other surgical techniques. Polyp recurrence and long-term adverse effects were uncommon.
