It has been suggested to have a negative effect on pituitary surgery; however, outcomes in this cohort have not been defined. This study was performed to determine the effect of ESS on immediate and long-term biochemical outcome after pituitary surgery for Cushing's disease (CD).<\/jats:p><\/jats:sec>\n\nMethods<\/jats:title>\nUsing a matched cohort study design, the authors followed patients treated with pituitary surgery for CD with and without ESS. Complete ESS was defined as pituitary gland height \u2264 2 mm, whereas partial ESS was defined as pituitary gland height > 2 mm but less than three-quarters of the total sellar depth. The primary end points were immediate and long-term biochemical outcome. Cerebrospinal fluid leaks were recorded as a secondary end point.<\/jats:p><\/jats:sec>\n\nResults<\/jats:title>\nSeventy-eight patients with CD and primary ESS were identified and matched with 78 patients with CD without ESS. After surgical management, immediate biochemical remission was achieved in 69 patients (88%) with ESS and 75 controls (96%, p = 0.10). Long-term remission was achieved in most patients in both groups (5-year cure: 85% vs 92%, p = 0.10). Among patients with ESS, the presence of complete ESS predicted a worse long-term outcome (p = 0.04). Intraoperative CSF leaks were significantly more frequent with ESS (54% vs 24%, p < 0.001), and despite sellar floor repair, the rate of postoperative CSF leaks was also increased (6% vs 3%, p = 0.27).<\/jats:p><\/jats:sec>\n\nConclusions<\/jats:title>\nBiochemical outcome after pituitary surgery for CD was worse in patients with complete ESS, and the risk of a CSF leak was increased with both partial and complete ESS. However, as outcome remains superior to those following alternative therapies and the biology of these tumors is unchanged in the setting of ESS, pituitary surgery should remain the initial treatment of choice.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2014.3.jns132012","type":"journal-article","created":{"date-parts":[[2014,5,23]],"date-time":"2014-05-23T14:59:45Z","timestamp":1400857185000},"page":"518-526","source":"Crossref","is-referenced-by-count":16,"title":["Effect of primary empty sella syndrome on pituitary surgery for Cushing's disease"],"prefix":"10.3171","volume":"121","author":[{"given":"Gautam U.","family":"Mehta","sequence":"first","affiliation":[{"name":"Surgical Neurology Branch, National Institutes of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Maryland; and"},{"name":"Department of Neurosurgery, University of Virginia Health Sciences Center, University of Virginia, Charlottesville, Virginia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamran D.","family":"Bakhtian","sequence":"additional","affiliation":[{"name":"Surgical Neurology Branch, National Institutes of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Maryland; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward H.","family":"Oldfield","sequence":"additional","affiliation":[{"name":"Surgical Neurology Branch, National Institutes of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Maryland; and"},{"name":"Department of Neurosurgery, University of Virginia Health Sciences Center, University of Virginia, Charlottesville, Virginia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-jns132012","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"510","DOI":"10.3171\/jns.1986.64.3.0510","article-title":"Familial acromegaly with pituitary adenoma.
