ABSTRACT:During the past 25 years, 77 giant pituitary adenomas have been treated surgically, including suprasellar extensions of type C in 66 cases and of type D in 11 cases. Non-secreting adenomas were present in 53 and secreting adenomas in 24 cases. All patients except 3 presented with significant visual field defects; including bitemporal hemianopia, superior quadranopia or unilateral temporal hemianopia, contralateral blindness in 73% of the cases, and one case with sudden bilateral blindness due to acute pituitary apoplexy. A single transsphenoidal procedure was carried out in 74% of the patients while 11 patients (7%) required re-operations for recurrent or residual tumor. Only 3 patients required a subsequent transcranial procedure. Complications included 1 CSF-leak, 1 empty-sella syndrome and 4 fatal post-operative hematomas. We prefer the transsphenoidal route even in very large or giant pituitary adenomas, since it allows rapid and adequate decompression of the optic nerves and chiasm, avoids major pituitary insufficiency in 60% of the cases and is associated with low morbidity-mortality rates.

A chronobiological study was carried out in headache syndromes due to empty sella or to pituitary G.H.- and PRL-secreting adenomas. In the empty sella syndrome only the chrono-organization of G.H. secretion was disturbed, whereas pl. PRL exhibited the usual circadian pattern. The circadian rhythms of pl. G.H. and pl. PRL were abolished in G.H.-and PRL-secreting pituitary tumors, respectively, and were again detectable when patients were cured by selective transsphenoidal adenomectomy. A normal circadian rhythmicity of pl. cortisol was demonstrable in the empty sella syndrome and in pituitary adenomas, both before and after surgery. On a étudié les aspects rhythmométriques de certains cas de céphalée secondaire à un atteinte sellaire ou bien hypophysaire, tels la syndrome de la selle vide et les adénomes GH- ou PRL-secrétants. Au cours du syndrome de la selle vide on observe un trouble de la rhythmicité circadienne du GHpl., tandis que les autres rhythmes (PRL et cortisol pl., température orale) sont normaux. Dans les adénomes GH- ou PRL-secrétants on observe une altération sélective du rhythme circadien de l'hormone spécifiquement secrétée par l'adénome. Après l'exérèse chirurgicale de l'adénome par voie transphénoidale, la normalization des niveaux plasmatiques hormonaux s'accompagne à la réapparition du rhythme circadien habituel. Le rhythme circadien du cortisol plasmatique ne semble pas être affecté par la présence d'une selle vide ou bien d'un adénome GH- ou PRL-secrétant ni par l'adenomectomie par voie transphénoidale. E’ stata attuata una indagine cronobiologica in corso di cefalea secondaria a patologie sellario ipofisarie, quali la sindrome della sella vuota e gli adenomi GH- o PRL-secernenti, con sindrome cefalalgica. In presenza di empty sella si riscontra un'alterazione della cronoorganizzazione circadiana solo per la secrezione di G.H., mentre la PRL pl. presenta il normale ritmo circadiano. Negli adenomi ipofisari si rileva la scomparsa della normale ritmicità circadiana dell'ormone specificamente ipersecreto e la completa rimozione dell'adenoma per via trans-nasosfenoidale è seguita dal ripristino del ritmo circadiano dell'ormone stesso. Il ritmo circadiano del cortisolo pl. non risulta alterato nell'empty sella nè in presenza di adenoma ipofisario GH o PRL-secernente e non viene significativamente modificato dall'intervento neurochirurgico.

Objective:  To review and report the results in pure endoscopic endonasal trans-sphenoidal surgery done at our unit for pituitary adenomas (PAs) in last 8 years. Material and Methods:  We reviewed 403 consecutive patients who underwent pure endoscopic endonasal trans-sphenoidal surgery for newly diagnosed pituitary adenomas between August 2012 and July 2020 at our neurosurgical unit. Endocrinological, demographic features and outcomes, their complications, and duration of stay in hospital were assessed in these patients who were operated in our neurosurgical Unit. The Mean Follow-up on average was 3.5 months. Results:  403 consecutive cases were reviewed. Majority of cases were in the 4th decade of life at presentation. 227 (56%) were non-functioning pituitary tumors and 176 (44%) were hormone secreting pituitary adenomas. Thirty-one (7.7%) complications were observed in 28 post-operative patients. The most frequently observed complication was diabetes insipidus (temporary in 19 (5%) and permanent in 3 (0.7%) cases), cerebrospinal fluids leaks (5 cases) (5.7%), Syndrome of inappropriate antidiuretic hormone (1 case) (0.2%), internal carotid injury (1 case) (0.2%), Empty Sella syndrome (1) (0.2%) and post-operative cardiac complication (1 case) (0.2%). The Follow-up on average was 3.5 months. Conclusions:  The pure endoscopic endonasal trans-sphenoidal surgery of pituitary adenomas provides acceptable and reasonable results representing a safe alternative procedure to the traditional Trans-sphenoidal microscopic approach.

✓ Selected cases are presented demonstrating evaluation of sellar and juxtasellar pathology with metrizamide cisternography. The compatibility of metrizamide with the current generation of computerized tomography scanners has provided complementary data to metrizamide-enhanced hypocycloidal tomographic studies of the sellar and juxtasellar areas. The ease and low morbidity of metrizamide cisternography relative to pneumography is outlined.
