摘要:

Obstruction of the spiral loop of the ascending colon (spiral colon) due to adhesions causing extraluminal constriction was diagnosed in 8 cows during a 2‐year period. The adhesions resulted from intraperitoneal injections in 7 cows and from previous intra‐abdominal surgery in the 8th. Surgical correction was performed in 4 of the cows by uniting the bowel proximal and distal to the obstruction, thus creating an intestinal bypass. Approximately half of the large intestine was bypassed in this manner in 3 cows; all but a portion of the descending colon and rectum was bypassed in the 4th. Each of the cows survived surgery, although 1 died 30 days later, possibly as a result of a second obstruction caused by further adhesions. Appetite, general physical condition, and milk production returned after celiotomy and intestinal bypass. Feces were loose after operation but gradually firmed to near‐normal consistency in 3 of the

摘要:

Four dairy calves were subjected to partial bypass of the large intestine by uniting the ileum to the distal centrifugal coil of the spiral loop of the ascending colon (spiral colon). Digesta bypassed the distal ileum, cecum, proximal loop of the ascending colon, and the centripetal coils of the spiral colon. The calves survived the surgical procedure and were healthy throughout the 4‐week postoperative experimental period. Feces were loose immediately after bypass, but fecal dry matter (DM) gradually increased over the subsequent 2 weeks (P<0.01), indicating adaptation of remaining bowel to absorb more water. There was no significant change in serum concentration of sodium or chloride. The calves continued to grow and gain weight at acceptable rates after bypass. Necropsy of 3 of the calves demonstrated a decrease in size of the bypassed bowe

摘要:

Tumor characteristics and degree of metastatic disease are outlined for 15 cases of canine thyroid carcinoma based on physical, laboratory, and radiographic examinations. Results of thyroid scintiscans using sodium pertechnetate are discussed in relation to clinical staging. Surgical resection was the primary therapy. Adjuvant therapy included thyroid replacement therapy, and131I and60Co radiotherapy.

摘要:

Lumbar dorsal laminectomies were performed on 24 dogs, and exposed spinal cords were subjected to various time‐temperature combinations of perfusion according to the following schedule: 1) 30 minutes of hypothermic perfusion—6 dogs; 2) 30 minutes of normothermic perfusion—6 dogs; 3) 120 minutes of hypothermic perfusion—6 dogs; and 4) 120 minutes of normothermic perfusion—6 dogs.Surgery, cord perfusion, and exposure of the dorsal aspects of the spinal cord to the epaxial musculature for 5 days following surgery produced histopathologic changes in the dorsal aspects of the cord, especially around the dorsal root area. Hypothermic spinal cord perfusion for 120 minutes produced a marked deleterious effect on normal spinal cord function and spinal cord tissue. Spinal cords exposed to 30 minutes of hypothermic or normothermic perfusion or 120 minutes of normothermic perfusion had less severe clinical and histopathologic changes than those exposed to 120 minutes of hypothermic perfusion. Hypothermic perfusion for 30 minutes and 120 minutes affected not only dorsal aspects of the cord, but also the grey matter. The most severe change in grey matter occurred in cords perfused for 12
