Official title
Prospective Multicenter Cohort Study Comparing Extent of Tumor Resection Between Microscopic Transsphenoidal Surgery and Fully Endoscopic Transsphenoidal Surgery for Nonfunctioning Pituitary Adenomas
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to compare the extent of resection (EOR) in patients with nonfunctioning pituitary adenomas undergoing transsphenoidal surgery using a microsurgical technique to those patients who have undergone surgery with a fully endoscopic technique. Another goal is to compare surgical complications, endocrine outcomes, visual outcomes, length of surgery, length of hospital stay, and readmission rates between the two transsphenoidal surgery techniques. This is an observational data collection study with no experimental procedures or experimental medicines. Endonasal transsphenoidal removal of a pituitary tumor is a unique procedure and there is little information comparing the two surgical techniques.
