BackgroundPineal tumors are rare, and the pineal region is a challenging surgical location for neurosurgeons. The present study aimed to investigate the effects of microsurgical management in patients with pineal region tumors and explore probable factors associated with preoperative hydrocephalus, postoperative hydrocephalus remission, and prolonged hospital length of stay (LoS).MethodsA retrospective study of patients with pineal region tumors who underwent microsurgical management at the First Affiliated Hospital of Soochow University (Jiangsu, China) between 1 January 2010 and 31 October 2022 was conducted.ResultsData from 36 patients were included in this study. The top 5 common symptoms included headache (58%), dizziness (44%), double vision (22%), vomiting (19%), and nausea (14%). Patients with a lower Karnofsky Performance Score (KPS), younger age, and larger maximum tumor diameters were more vulnerable to preoperative hydrocephalus. Preoperative hydrocephalus also led to a prolonged postoperative LoS (P = 0.021). Patients with a lower KPS score (P = 0.020) or larger maximum tumor diameters (P = 0.045) were more likely to achieve postoperative remission of hydrocephalus. Most postoperative complications led to increased hospital LoS.ConclusionsMicrosurgical resection of pineal tumors yielded favorable long-term outcomes. Patients with a lower KPS score, younger age, and larger maximum tumor diameters were more vulnerable to preoperative hydrocephalus and prolonged LoS. Patients with a lower KPS score or larger tumor diameter were likely to achieve significant remission of hydrocephalus after tumor resection.Copyright © 2024 Elsevier Inc. All rights reserved.
