Transsphenoidal pituitary surgery in the elderly is safe and effective

Area of Science:

• Neurosurgery
• Endocrinology
• Geriatric Medicine

Background:

• The aging population is experiencing a rise in pituitary tumor diagnoses.
• Concerns exist regarding increased anesthetic risks, peri-operative morbidity, and mortality in elderly patients undergoing pituitary surgery.
• Auditing outcomes in this demographic is crucial for patient care.

Purpose of the Study:

• To audit the benefits and complications of transsphenoidal surgery in elderly patients (age ≥ 70 years).
• To evaluate the safety and efficacy of pituitary surgery in an aging population.
• To compare outcomes between microscopic and endoscopic surgical approaches.

Main Methods:

• Retrospective data collection of patients aged 70 and above undergoing transsphenoidal surgery.
• Study period: November 2003 to August 2012 at a large tertiary referral center.
• Analysis of intra-operative, 30-day, and long-term complications, as well as functional outcomes.

Main Results:

• 104 operations were performed on 102 elderly patients (median age 75.2 years).
• Low complication rates: transient diabetes insipidus (9.6%), SIADH (8.7%), and no peri-operative deaths.
• Significant improvements observed in visual fields (91%) and endocrine function (79% improved/stable).

Conclusions:

• Transsphenoidal surgery is a safe and effective intervention for elderly patients with pituitary tumors.
• Both microscopic and endoscopic approaches yield low morbidity and mortality.
• The procedure offers significant benefits for symptom control and functional outcomes in older adults.
