Pituitary Apoplexy: Should Endoscopic Surgery Be the Gold Standard?

Background Pituitary apoplexy is an uncommon, potentially fatal condition due to spontaneous ischemia or hemorrhage in a pituitary adenoma. The treatment of this disorder has long been a matter of debate. Methods Retrospective cohort study including all patients admitted with pituitary apoplexy in our department between 2005 and 2015 was undertaken. Clinical symptoms and signs on admission, treatment (conservative vs. surgical), neurologic deficit on discharge and at 6 months' follow-up, and endocrinologic evaluation at 6 months' follow-up were analyzed. The statistical analysis was performed with STATA 13.0. Endocrinologic and visual outcomes at 6 months in the different groups according to treatment were compared by applying an independent multinomial probit regression test. Outcomes between the conservative and the surgical (endoscopic and microscopic considered together) groups also were compared and the differences between surgical treated groups were analyzed with logistic regression analysis. P values Results Twenty-three patients were included in this study; 60.9% ( n  = 14) were treated surgically (5 microsurgically; 9 endoscopically) and 39.1% ( n  = 9) conservatively. Statistical analysis revealed no significant differences in the visual function between the 3 treatment groups in both univariate and multivariate analysis ( P  > 0.05). The endocrinologic outcome was better in the surgical group ( P  = 0.017; adjusted P  = 0.027), with a significant difference between the conservative group and the endoscopic group ( P  = 0.004; adjusted P  = 0.005). When we compared both surgical groups, the endoscopic group has a better endocrinologic outcome ( P  = 0.020; adjusted P  = 0.012). Conclusions Our results support endoscopic intranasal transsphenoidal surgery as a treatment of pituitary apoplexy patients, as it probably decreases the need for long-term hormonal replacement.
