The Surgical Results in Pure Endoscopic Endonasal Trans-sphenoidal Surgeries in 403 Pituitary Adenomas: An 8-Years of Experience from a Single Neurosurgical Unit
Objective: To review and report the results in pure endoscopic endonasal trans-sphenoidal surgery done at our unit for pituitary adenomas (PAs) in last 8 years.
Material and Methods: We reviewed 403 consecutive patients who underwent pure endoscopic endonasal trans-sphenoidal surgery for newly diagnosed pituitary adenomas between August 2012 and July 2020 at our neurosurgical unit. Endocrinological, demographic features and outcomes, their complications, and duration of stay in hospital were assessed in these patients who were operated in our neurosurgical Unit. The Mean Follow-up on average was 3.5 months.
Results: 403 consecutive cases were reviewed. Majority of cases were in the 4th decade of life at presentation. 227 (56%) were non-functioning pituitary tumors and 176 (44%) were hormone secreting pituitary adenomas. Thirty-one (7.7%) complications were observed in 28 post-operative patients. The most frequently observed complication was diabetes insipidus (temporary in 19 (5%) and permanent in 3 (0.7%) cases), cerebrospinal fluids leaks (5 cases) (5.7%), Syndrome of inappropriate antidiuretic hormone (1 case) (0.2%), internal carotid injury (1 case) (0.2%), Empty Sella syndrome (1) (0.2%) and post-operative cardiac complication (1 case) (0.2%). The Follow-up on average was 3.5 months.
Conclusions: The pure endoscopic endonasal trans-sphenoidal surgery of pituitary adenomas provides acceptable and reasonable results representing a safe alternative procedure to the traditional Trans-sphenoidal microscopic approach.
