Abstract
OBJECTIVES: This study was conducted to investigate complications and outcome by endonasal endoscopic approach in our single center. PATIENTS AND METHODS: The clinical data of 2032 pituitary adenoma surgeries performed in our ward between January 2006 and December 2018 were retrospectively reviewed. The GTR (gross total resection) rate, hormonal control, complications, and tumor recurrence rate were retrospectively analyzed. RESULTS: There were 628 (83.5 %) preoperative headache patients, 513 (68.9 %) visual acuity and visual field impaired patients, 218 (66.4 %) endocrine symptom patients and 26 (53.1 %) SIADH (syndrome of inappropriate secretion of antidiuretic hormone) patients experienced improvement after surgery. GTR was achieved in 1627 patients (80.1 %) and NGTR (non-gross total resection) in 405 patients (19.9 %). Clinically variable analyses revealed a significant correlation between GTR and Knosp's grades, large tumor volume, bone-invasive and recurrent tumors. Postoperative complications mainly included 34 (1.7 %) CSF (cerebral spinal fluid) leak, 72 (3.5 %) pituitary insufficiency, 30 (1.5 %) meningitis, 20 (0.98 %) cranial nerve deficits, 5 (0.25 %) hematoma, 5 (0.25 %) patients with internal carotid artery injury, and other complications mainly included nasal complications occurred in 168 patients (8.6 %). Overall, there were 3 deaths (0.15 %) occurred in our series. Univariate analysis showed that larger tumors, invasion, bone invasive, recurrent tumors and NGTR were associated with tumor regrowth. Multivariate analysis showed that NGTR and invasion were independent risk factors for tumor regrowth. CONCLUSIONS: NGTR and invasion were independent risk factors for tumor regrowth. Endoscopic surgery is an excellent choice for pituitary adenomas. It has the advantages of being minimally invasive, safe, and efficacious.
