abstract
BACKGROUND: Transsphenoidal surgery (TSS) is a common procedure for a variety of pituitary lesions. This procedure can be associated with complications related to the surgery or specific pathology. In this study, we evaluate inpatient postoperative complications among patients who underwent TSS for growth hormone adenomas using a nationally representative database, and compare patient characteristics and complications to patients who underwent TSS for other benign pituitary neoplasms. METHODS: Analysis of the Nationwide Inpatient Sample revealed 13,070 TSS patients (including 892 with acromegaly) between 2002 and 2010. Complication rates, outcomes, patient demographics, hospital stay, and total charges were evaluated among TSS patients with and without acromegaly. RESULTS: There was an increase in TSS performed in both cohorts from 2002 to 2010. Acromegaly patients were younger, had shorter hospital stays, and incurred fewer charges. Acromegaly patients had a lower occurrence of postoperative urinary/renal complications (0.2% vs 1.1%), thromboembolic events (0% vs 0.4%), fluid/electrolyte abnormalities (5.7% vs 9.1%), and iatrogenic hypopituitarism (0.3% vs 1.1%) compared to other TSS patients (all p < 0.05). After adjusting for age, acromegalic patients maintained a statistically lower occurrence of fluid/electrolyte abnormalities (p = 0.007). Cerebrospinal fluid leak occurrence in acromegaly patients was 2.6% vs 1.7% in non-acromegaly patients, a result that did not reach significance (p = 0.054). CONCLUSION: Upon comparison of inpatient hospitalizations for patients undergoing TSS for growth hormone adenomas and other benign pituitary neoplasms, acromegaly patients had a significantly lower occurrence of postoperative fluid/electrolyte abnormalities. Acromegaly patients had shorter hospitalizations and subsequently fewer total charges.
