Aim Of The StudyThe paper presents endoscopic surgical technique used in the treatment of hormonally active pituitary adenomas and assessment of the method in terms of its effectiveness and safety.Material And MethodsIn 217 cases the surgery was performed due to pituitary adenomas applying the technique developed by Jho and Carrau, with our own modifications. 70 patients were treated for hormonally active adenomas. The group consisted of 36 somatotrophic adenomas, 21 prolactinomas and 13 corticotrophic adenomas. There were 51 females and 19 males with mean age of 42.6 years (range 11-77 years). The follow-up period was between 7 and 56 months (mean - 34 months). The effectiveness and occurrence of complications were confirmed on the basis of neurosurgical, laryngological, endocrinological, ophthalmological examinations and neuroimaging.ResultsBiochemical and neurosurgical criteria for complete resection were obtained in 21 (58.3%) of 36 patients with all somatotrophic adenomas. In the group of prolactinomas complete resection was achieved in 17 (80.9%) of 21 patients. Of the 13 patients with Cushing's disease 11 (84.6%) were cured. In the studied group there were no deaths. In the postoperative course only 2 (2.8%) patients suffered liquorrhoeas and new anterior lobe pituitary insufficiency was noted in 8 (11.4%) cases. Meningitis was noted in 1 (1.4%) case and another 1 (1.4%) patient had epistaxis which required repeated endoscopic surgery.ConclusionsEndoscopic technique is an effective method of treatment of hormonally active pituitary adenomas. It is characterised as being minimal invasive and has a low severe complication rate.
