Vessel-sealing device vs conventional hemostatic techniques for thyroidectomy
Benefit(s) of using a vessel-sealing device for thyroidectomy?

Answer 1

Lorange, JAVMA, 2019:
Use of a vessel-sealing device resulted in shorter operative times but did not affect complication rates or post-op hospitalization times

Question 2

Reagan, JAVMA, 2019:
Unilateral thyroidectomy in dogs
Peri-op complication rate?
Most common intra-op complication?
Most common post-op complication?
Mortality rate?
MST?

Answer 2

Reagan, JAVMA, 2019:
Peri-op complication rate: 20%
Most common intra-op complication: hemorrhage (8%)
Most common post-op complication: aspiration pneumonia (3%)
Mortality rate: 2%
MST: 911 days

Question 3

Singh, Vet Surg, 2019:
Surgical treatment of primary hyperparathyroidism in cats
What % of the tumors were parathyroid adenoma and what % were carcinoma?
Calcium levels at discharge?
Correlation between pre-op and post-op iCa?
Pre-op iCa, hypocalcemia or hypercalcemia at discharge, or a diagnosis of carcinoma were not associated with survival time - true or false?

Answer 3

Singh, Vet Surg, 2019:
63% adenoma, 22% carcinoma
At discharge, 19% were hypercalcemic, 16% were hypocalcemic, and 65% were normocalcemic
No correlation between pre-op and post-op iCa
True
