Endoscopic Versus Microscopic Transsphenoidal Surgery for Pituitary Tumors

Abstract

These data conclude that, compared with MTS, ETS needs longer operation time and results in more intraoperative blood loss, but appears to achieve higher GTR rate for Knosp grade III pituitary tumors.

Challenges, Learning Curve, and Safety of Endoscopic Endonasal Surgery of Sellar-Suprasellar Lesions in a Community Hospital

“…2%. [22][23][24][25][26][28][29][30][31][32][33][35][36][37][38][39][40][41][42][43]50 The rate of recovery from hormonal deficits in our study is greater than that found by other researchers. Most of our patients (83.9%) showed stable or improved hormonal deficits.…”

“…Other studies have reported rates of vision improvement from as low as 23% to as high as 100%. [22][23][24][25][26][28][29][30][31][32][33][34][37][38][39][40][41][42][43]50 In our study, no patients had worsened vision after surgery. This is consistent with results found by other researchers who generally saw a very low rate of worsened visual deficits after surgery, on the order of 0%e3.…”

“…Many studies show a similar if not greater efficacy of EES compared with the gold standard microsurgical techniques. 26,42,44 This is the first study to look for the outcomes of patients undergoing endoscopic transnasal sellar, suprasellar, and anterior cranial fossa lesion excisions in a community hospital setting. It has also been demonstrated that the transition to EES is hindered by its learning curve, although the details of this learning curve and its clinical implications have not been studied in detail.…”

“…Rates of new deficits in other studies have ranged from 0% to 20%. [22][23][24][25][26][27][28][29][30][31][32][33]35,[37][38][39][40][41][42][43][50][51][52][53][54] Perioperative complications that we analyzed include the rates of hematoma requiring evacuation, diabetes insipidus, CSF leak, and meningitis. Our patients experienced a similar rate of postoperative hematoma when compared with previous studies described in the literature.…”

“…In our literature review, the rate of this complication ranged from 0% to 3%. 24,[26][27][28][29]33,35,39,40,42,43 Two (3. 6%) of our patients experienced this complication and required surgical evacuation of the hematoma.…”
