TL;DR: The number one cause of insulin resistance in cats is Hypersomatotropism (HST) with hypercortisolism (HC) occupying a more distant second place as discussed by the authors .
Abstract: True insulin resistance should be differentiated from management-related difficulties (eg, short insulin duration, inappropriate insulin injection, inappropriate storage). Hypersomatotropism (HST) is the number one cause of insulin resistance in cats , with hypercortisolism (HC) occupying a more distant second place. Serum insulinlike growth factor-1 is adequate for screening for HST, and screening at the time of diagnosis, regardless of presence of insulin resistance, is advocated. Treatment of either disease centers on removal of the overactive endocrine gland (hypophysectomy, adrenalectomy) or inhibition of the pituitary or adrenal glands by using drugs such as trilostane (HC), pasireotide (HST, HC) or cabergoline (HST, HC).

TL;DR: In this paper , the most common approaches to pituitary surgery are the Microscopic and endoscopic transsphenoidal approaches (MA and EA), respectively, and the authors aim to expand on previous studies and describe national trends in approaches to Pituitary Surgery through 2021 including geographic trends and postoperative outcomes.
Abstract: Introduction: Microscopic and endoscopic transsphenoidal approaches are the most common approaches to pituitary surgery. Previous studies utilizing US-based databases from 2003 to 2014 have demonstrated early predominance of microscopic approaches (MA), though rates of endoscopic approaches (EA) increased toward 2014. The current study aims to expand on previous studies and describes national trends in approaches to pituitary surgery through 2021 including geographic trends and postoperative outcomes.

TL;DR: Transsphenoidal hypophysectomy (TSH) is the removal of the pituitary gland via the sphenoid bone as mentioned in this paper , which is the most common procedure for TSH.
Abstract: Hypophysectomy is the removal of the pituitary gland. Transsphenoidal hypophysectomy (TSH) is the removal of the pituitary gland via the sphenoid bone. Nonfunctional sellar masses in the dog and cat have been treated medically with a corticosteroid to control brain edema. Case selection for hypophysectomy in veterinary medicine is dependent on clinical signs, endocrine testing, tumor size, and concurrent co-morbidities in a given patient. Postoperative management of these patients includes monitoring of vital signs, neurological status, fluid intake and output, serum electrolyte concentrations, palate incision site, and tear production. The optic chiasm and optic nerves are parasellar structures that can be damaged while performing TSH and lead to blindness. Long-term follow up is necessary for optimal success post-TSH. Because TSH causes diabetes insipidus, hypothyroidism, and hypoadrenocorticism, specific parameters will need to be monitored regularly post-surgery.
