Complications in Endoscopic Endonasal Pituitary Adenoma Surgery: An Institution Experience in 310 Patients

Abstract

Objective Endoscopic endonasal approaches (EEAs) have shown excellent results for majority of hypophyseal tumors. The aim of this study was to evaluate and report the complications of EEA in patients with pituitary adenoma (PA) who underwent surgery between 2013 and 2018.

Methods We performed a retrospective review of 310 consecutive patients/325 procedures with PA treated with an EEA from May 2013 to January 2018. Minor complications including transient diabetes insipidus (DI) or new anterior pituitary hormone insufficiency in one axis and major complications including CSF leakage, hematoma needing reoperation, vascular damage, brain infection, new pan-hypopituitarism permanent DI, new visual impairment, neurological deficits, and mortality were recorded.

Results We encountered 58 complications in 310 patients (18.7%) and 325 procedures (17.7%). Minor complications were 43 (13.9 and 13.2%) in 310 patients and in 325 procedures, respectively; whereas, major complications were 28 (9 and 8.6%, respectively). Total complications were associated with diameter group 2 (>30 mm), diaphragm sella violation, suprasellar extension, parasellar involvement, nonfunctional secretory type, and intraoperative arachnoid tearing.

Conclusion EEA can be considered as a safe surgical treatment which has acceptable complications in the management of PAs.
