Abstract

Background Inconsistent findings have been reported regarding the efficacy and safety of endoscopic and microscopic transsphenoidal surgery for pituitary adenoma. This study aimed to assess the benefits and shortcomings of these surgical methods in patients with pituitary adenoma. Methods The electronic databases PubMed, Embase, and the Cochrane Library were systematically searched, as well as proceedings of major meetings. Eligible studies with a retrospective or prospective design that evaluated endoscopic versus microscopic methods in patients with pituitary adenoma were included. Primary outcomes included gross tumor removal, cerebrospinal fluid leak, diabetes insipidus, and other complications. Results Overall, 23 studies (4 prospective and 19 retrospective) assessing 2272 patients with pituitary adenoma were included in the final analysis. Endoscopic transsphenoidal surgery was associated with a higher incidence of gross tumor removal (odds ratio, 1.52; 95% confidence interval, 1.11–2.08; P = 0.009) than those with microscopic transsphenoidal surgery. In addition, endoscopic transsphenoidal surgery had no significant effect on the risk of cerebrospinal fluid leak, compared with microscopic transsphenoidal surgery. Furthermore, endoscopic transsphenoidal surgery was associated with a 22% reduction in risk of diabetes insipidus compared with microscopic transsphenoidal surgery, but the difference was not statistically significant. Endoscopic transsphenoidal surgery significantly reduced the risk of septal perforation (odds ratio, 0.29; 95% confidence interval, 0.11–0.78; P = 0.014) and was not associated with the risk of meningitis, epistaxis, hematoma, hypopituitarism, hypothyroidism, hypocortisolism, total mortality, and recurrence. Conclusions Endoscopic transsphenoidal surgery is associated with higher gross tumor removal and lower incidence of septal perforation in patients with pituitary adenoma. Future large-scale prospective randomized controlled trials are needed to verify these findings. [ABSTRACT FROM AUTHOR]
