Endoscopic Endo-Nasal Trans-Sphenoidal Excision of Pituitary Tumors: An Institutional Experience.

To analyze the clinical presentation, management and outcomes of patients with pituitary adenoma treated by Endoscopic Endo-nasal Trans-sphenoidal (EETS) excision. Study was conducted on the basis of medical records of 14 patients who had undergone EETS excision of pituitary adenomas. The data obtained was assessed for demographic and clinical characteristics, radiographic features and post-operative outcomes. Study included 10 males and 4 females. Mean age of patients was 46.43 years (range 16-70 Years). Most common presentation was diminished vision reported in 79% patients. Features of acromegaly encountered in 21% cases. Location of majority of tumors was sellar with supra-sellar extension (71%) followed by sellar (14%), sellar with para-sellar extension (7%) and sellar with supra-sellar and para-sellar extensions (7%). Total tumor resection was achieved in 64% cases and sub-total resection in 36% cases. One of the lesions on biopsy revealed granulomatous pathology. No post-operative complication was seen in 71% patients. Transient Diabetes Insipidus was observed in 21% cases that resolved within 3-4 days. One patient expired due to meningitis and septicemia. One patient had CSF leak that was effectively managed by placing lumbar drain. There was significant improvement in visual symptoms and hormonal levels. Average hospital stay was 13.54 days and mean follow up period was 13 months. EETS approach is safe, minimally invasive and effective surgical technique for resection of pituitary adenomas with low post-operative morbidity, reduced hospital stay and better remission of symptoms.
