Complications following endoscopic transsphenoidal surgery for pituitary adenoma—special focus on intrasellar pressure

This study confirms earlier findings of low age as a possible risk factor for postoperative cerebrospinal fluid leakage. Tumor volume is suggested to be associated with higher complication risk. ISP does not seem to be a significant risk factor for intraoperative events or postoperative complications following ETS. Predictive risk factors for surgical complications after ETS are still not satisfactorily explained and heterogeneous definitions of complications are problematic in this context.
