Abstract
PURPOSE The success and outcomes of repeat endoscopic transsphenoidal surgery (ETS) for residual or recurrent Cushing's disease (CD) are underreported in the literature. This study aims to address this gap by assessing the safety, feasibility, and efficacy of repeat ETS in these patients. METHODS A retrospective analysis was conducted on 56 patients who underwent a total of 65 repeat ETS performed by a single neurosurgeon between January 2006 and December 2020. Data including demographic, clinical, laboratory, radiological, and operative details were collected from electronic medical records. Logistic regression was utilized to identify potential predictors associated with sustained remission. RESULTS Among the cases, 40 (61.5%) had previously undergone microscopic surgery, while 25 (38.5%) had prior endoscopic procedures. Remission was achieved in 47 (83.9%) patients after the first repeat ETS, with an additional 9 (16.1%) achieving remission after the second repeat procedure. During an average follow-up period of 97.25 months, the recurrence rate post repeat surgery was 6.38%. Sustained remission was achieved in 48 patients (85.7%), with 44 after the first repeat ETS and 4 following the second repeat ETS. Complications included transient diabetes insipidus (DI) in 5 (7.6%) patients, permanent (DI) in 2 (3%) patients, and one case (1.5%) of panhypopituitarism. Three patients (4.6%) experienced rhinorrhea necessitating reoperation. A serum cortisol level > 5 µg/dL on postoperative day 1 was associated with a reduced likelihood of sustained remission. CONCLUSION Repeat ETS is a safe and effective treatment option for residual or recurrent CD with satisfactory remission rates and low rates of complications.

Abstract
OBJECTIVE As surgical techniques become less invasive, the use of endoscopy in brain surgery supports this trend. Numerous endoscopic surgical approaches have been defined, especially for skull base diseases. The current study summarizes our experience of using the rarely reported endoscopic transnasal transdiaphragmatic approach through the existing hole in the diaphragma sella to access lesions extending into the suprasellar region. METHODS Our surgical team performed 4876 endoscopic endonasal surgeries between August 1997 and December 2022 at the Department of Neurosurgery, Pituitary Research Center, Faculty of Medicine, Kocaeli University. The study retrospectively analyzed data from 11 patients who had undergone endoscopic transnasal transdiaphragmatic surgery since January 2020. Preoperative and postoperative magnetic resonance imaging, pituitary function examination, and clinical observation were carried out. RESULTS The mean age of the patients was 31.1 ± 10.7 years and the female/male ratio was 6:5. Pathologic subtypes observed included breast cancer metastasis (n = 1), adrenocorticotropic hormone-secreting adenoma (n = 4), growth hormone-secreting adenoma (n = 3), craniopharyngioma (n = 2), and Rathke cleft cyst (n = 1). The mean postoperative hospital stay was 4.7 ± 1.1 days and none of the patients showed cerebrospinal fluid leakage during this period. CONCLUSIONS The endoscopic transnasal transdiaphragmatic approach may be considered an alternative to the conventional extended endoscopic transnasal approach in patients with lesions extending into the suprasellar region. The main strength of this method is that it facilitates suprasellar region access through a small dural incision and bone defect in the base of the skull. As a result, it also reduces the risk of postoperative cerebrospinal fluid leakage and associated complications.

Abstract
Patients with Cushing's disease (CD) who underwent endoscopic transsphenoidal surgery (ETS) with a layered peel strategy at our center were retrospectively analyzed. Records on patients' basic characteristics, preoperative and early postoperative evaluations, perioperative complications, and follow-up were collected. A total of 12 unselected, consecutive patients with CD were identified. Ten of the twelve patients were female. All tumors were confirmed by magnetic resonance imaging, with a maximum tumor diameter ranging from 5 mm to 11 mm. A lower rate of surgical complications was identified postoperatively, with no cases of carotid artery injury, epistaxis, hematoma, visual disturbance, or intracranial infection, but with one case of cerebrospinal fluid rhinorrhea. Ten patients experienced immediate remission, and two had delayed remission. No recurrence events were observed during a median follow-up of 51 months. In conclusion, our preliminary experience indicated that ETS with a layered peel strategy provided a perfect remission rate, low complication rate, and no recurrence in a case series of CD patients. Given the limited number of cases, future studies are warranted to confirm its effectiveness and safety.

Abstract
OBJECTIVES In this systematic review and meta-analysis, we review the literature regarding patients with Cushing's disease (CD) with negative or inconclusive magnetic resonance imaging (MRI). METHODS A quantitative systematic review was performed. Article selection was performed by searching MEDLINE (using PubMed), EMBASE, and Cochrane electronic bibliographic databases. RESULTS 28 articles described surgical management of inconclusive MRI or MRI-negative CD. A total of 858 patients underwent surgery for their Cushing adenoma. Different types of surgery, including endoscopic endonasal transsphenoidal surgery (EETS) (190 cases) and microscopic endonasal transsphenoidal surgery (METS) (488 cases), were performed on patients with MRI-negative CD. 7 studies, which included 164 patients, did not describe any surgery. EETS and METS are conducted to achieve selective adenomectomy (231 cases), partial adenomectomy (80 cases), total adenomectomy (13 cases), hemihypophysectomy (15 cases), or enlarged adenomectomy (48 cases). Based on available data on these studies, the remission rate, persistence rate, and recurrence rate after different types of surgeries on patients with MRI-negative CD were 72.97%, 27.03%, and 12.05%, respectively. There was no statistically significant difference between EETS and METS in the subanalysis regarding recurrence rate, remission rate, and persistence rate. However, the recurrence rate in the METS group is almost 3 times higher than in the EETS group. CONCLUSIONS Surgery has a good prognosis in patients with MRI-negative CD in terms of remission, and EETS has a lower rate of disease recurrence than METS; therefore, EETS seems to be the potential recommended treatment technique, while to confirm the therapeutic method of choice, further investigations should be done.

Abstract
OBJECTIVE The aim of this study was to investigate the effectiveness, safety, complications, and prognosis of endoscopic endonasal surgery for pituitary adenomas with cavernous sinus invasion (CSI). METHODS The clinical data of 803 pituitary adenomas with CSI surgeries performed in our single ward between January 1, 2006 and December 31, 2018 were retrospectively reviewed. The resection degree, bone invasion, endocrine examination, complications, and outcome were retrospectively summarized. RESULTS Gross total resection was achieved in 394 patients (49.1%) subtotal resection in 171 patients (21.3%) and partial resection in 238 patients (29.6%). Clinically variable analyses showed that there was a significant correlation between CSI and female, older age, operation history, and non-gross total resection (NGTR). Among the pituitary adenomas with CSI, there was a significant correlation between bone invasive and NGTR, Knosp classification, recurrence. K-M curves showed that young age, larger tumors, bilateral invasion, Grade 4 of Knosp classification, NGTR, and bone invasion were associated with pituitary adenomas regrowth. Multivariate analysis revealed that bone invasion, NGTR, and Grade 4 of Knosp classification were independent risk factors for pituitary adenomas regrowth. There was a significant correlation between CSI and female, older age, operation history, and tumor resection degree. CONCLUSIONS There was a significant correlation between CSI and female, older age, operation history, and tumor resection degree. The patients with CSI and bone invasion were likely to recurrent. Non-gross total resection, bone invasion, and Grade 4 of Knosp classification were independent risk factors for pituitary adenomas regrowth. Endoscopic endonasal surgery is an excellent choice for pituitary adenomas with CSI.

Abstract
OBJECTIVE Machine learning (ML) is an innovative method to analyze large and complex data sets. The aim of this study was to evaluate the use of ML to identify predictors of early postsurgical and long-term outcomes in patients treated for Cushing disease (CD). METHODS All consecutive patients in our center who underwent surgery for CD through the endoscopic endonasal approach were retrospectively reviewed. Study endpoints were gross-tumor removal (GTR), postsurgical remission, and long-term control of disease. Several demographic, radiological, and histological factors were assessed as potential predictors. For ML-based modeling, data were randomly divided into 2 sets with an 80% to 20% ratio for bootstrapped training and testing, respectively. Several algorithms were tested and tuned for the area under the curve (AUC). RESULTS The study included 151 patients. GTR was achieved in 137 patients (91%), and postsurgical hypersecretion remission was achieved in 133 patients (88%). At last follow-up, 116 patients (77%) were still in remission after surgery and in 21 patients (14%), CD was controlled with complementary treatment (overall, of 131 cases, 87% were under control at follow-up). At internal validation, the endpoints were predicted with AUCs of 0.81-1.00, accuracy of 81%-100%, and Brier scores of 0.035-0.151. Tumor size and invasiveness and histological confirmation of adrenocorticotropic hormone (ACTH)-secreting cells were the main predictors for the 3 endpoints of interest. CONCLUSIONS ML algorithms were used to train and internally validate robust models for all the endpoints, giving accurate outcome predictions in CD cases. This analytical method seems promising for potentially improving future patient care and counseling; however, careful clinical interpretation of the results remains necessary before any clinical adoption of ML. Moreover, further studies and increased sample sizes are definitely required before the widespread adoption of ML to the study of CD.

Abstract
Introduction The endoscopic endonasal transsphenoidal approach to the sella and parasellar regions is now increasingly used for removal of a variety of lesions localized in the ventral skull base. The advantage of the endoscope is enhanced visualization and improved panoramic view that can result in more complete removal of the tumor. An extensive knowledge of the anatomy is mandatory to approach this region. Materials and methods From February 2009 to March 2020, the endoscopic endonasal approach was used in 153 patients with sellar and parasellar lesions, at our Institution: 136 pituitary adenomas, 7 craniopharyngiomas, 3 Rathke’s cysts, a tuberculum sellae meningioma, an aneurysm of the internal carotid artery (ICA), a clivus chordoma, a papillary glioneuronal tumor, an histiocytosis, a pituitary metastasis from breast cancer and a chondrosarcoma. Results The most common surgical complications were cerebral spinal fluid leak (9), bleeding (2), pituitary abscess (2). Among endocrinological complications, the most important were diabete insipidus (23) and panhypopituitarism (3). Two patients complicated with meningitis. There were no visual worsening and no operative mortality. We had persistence of disease in 20 cases. Twelve patients underwent surgical revision for recurrence of the disease. Conclusions Pre-operative planning and collaboration with several specialists are necessary in order to offer the patient the best treatment, minimizing complications.

Abstract
Background This study was performed to examine the efficacy of endoscopic transsphenoidal surgery (ETS) for Cushing's disease at a single institute and to review past reports. Material and Methods We studied eight consecutive patients who underwent ETS for Cushing's disease. The radiological evaluation comprised a detailed examination of preoperative magnetic resonance images (MRIs), including inferior petrosal sinus sampling, for cases with normal renal function. Remission was evaluated at least three months after surgery and was defined by the presence of hypocortisolemia that required steroid replacement therapy or eucortisolemia with suppression to <1.8 μg/dL after 1mg of dexamethasone. Results In all cases preoperative MRI was abnormal and included two macroadenomas (25 %). Pathological confirmation of an adenoma was possible in all patients. The mean follow-up period was 5.6 (2-7) years. Remission was confirmed in 75.0% of the cases and was higher in rate for microadenoma (100%) than for macroadenoma (50%). Postoperatively , no cerebrospinal fluid rhinorrhea occurred, but new endocrine deficits were noted in 25% of patients. Conclusion Based on this study, ETS enhanced the intrasellar identification of adenomatous tissue, which led to low remission and complication rates that were comparable with those of traditional microsurgery for Cushing's disease.

Abstract
BACKGROUND Transsphenoidal surgery (TSS) to resect an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is the first-line treatment for Cushing's disease (CD), with increasing usage of endoscopic transsphenoidal (ETSS) technique. The aim of this study was to assess remission rates and postoperative complications following ETSS for CD. METHODS A retrospective analysis of a prospective single-surgeon database of consecutive patients with CD who underwent ETSS between January 2012-February 2020. Post-operative remission was defined, according to Endocrine Society Guidelines, as a morning serum cortisol < 138 nmol/L within 7 days of surgery, with improvement in clinical features of hypercortisolism. A strict cut-off of < 50 nmol/L at day 3 post-op was also applied, to allow early identification of remission. RESULTS A single surgeon (MJ) performed 43 ETSS in 39 patients. Pre-operative MRI localised an adenoma in 22 (56%) patients; 18 microadenoma and 4 macroadenoma (2 with cavernous sinus invasion). IPSS was carried out in 33 (85%) patients. The remission rates for initial surgery were 87% using standard criteria, 58% using the strict criteria (day 3 cortisol < 50 nmol/L). Three patients had an early repeat ETSS for persistent disease (day 3 cortisol 306-555 nmol/L). When the outcome of repeat early ETSS was included, the remission rate was 92% (36/39) overall. Remission rate was 94% (33/35) when patients with macroadenomas were excluded. There were no cases of CSF leakage, meningitis, vascular injury or visual deterioration. Transient and permanent diabetes insipidus occurred in 33 and 23% following first ETSS, respectively. There was one case of recurrence of CD during the follow-up period of 24 (4-79) months. CONCLUSION Endoscopic transsphenoidal surgery produces satisfactory remission rates for the primary treatment of CD, with higher remission rates for microadenomas. A longer follow-up period is required to assess recurrence rates. Patients should be counselled regarding risk of postoperative diabetes insipidus.

Abstract
PURPOSE Transsphenoidal surgery (TSS) is the first-line treatment for Cushing's disease (CD). This review aimed to synthesize the remission and recurrence rates following TSS for CD and identify predictors of these outcomes. METHODS Medline (1946-) and Embase (1947-) were searched until 23rd January 2019 for original studies. A meta-analysis was performed of remission and recurrence rates. Studies were excluded if patients had prior radiosurgery/radiotherapy, mixed pathologies or interventions without separated data, follow-up not reported or population size < 20. For recurrence rate syntheses, studies with follow-up < 6 months were excluded. RESULTS The search produced 2663 studies, of which n = 68 were included, involving 5664 patients. Remission rates after primary and revision TSS were 80% [77-82] and 58% [50-66] at last follow-up. After primary TSS, predictors of remission were micro- v macroadenomas (83% v 68%, p < 0.01), imaging-visible adenomas (81% v 69%, p < 0.01), adenomas confirmed on histopathology (87% v 45%, p < 0.01), absence of cavernous sinus invasion (80% v 30%, p < 0.01), postoperative serum cortisol (MSeC) nadir < 2 μg/dL (< 55 nmol/L; 95% v 46%, p < 0.01) and lower preoperative 24-h urine free cortisol (1250 nmol v 1726 nmol, p < 0.01). For revision TSS, predictors of remission were postoperative MSeC nadir < 2 μg/dL (< 55 nmol/L; 100% v 38%, p < 0.01) and operations for recurrence v persistence (80% v 54%, p < 0.01). Recurrence rates after primary and revision TSS were 18% [14-22] and 28% [16-42]. CONCLUSIONS TSS is most effective in primary microadenomas, visible on preoperative imaging and without CS invasion, lower preoperative 24-h urine free cortisol and postoperative MSeC nadir < 2 μg/dL (< 55 nmol/L).

Results and predictors of outcome of endoscopic endonasal surgery in Cushing's disease: 20-year experience of an Italian referral Pituitary Center. J Endocrinol Invest 2020; 43:1463-1471. [PMID: 32215861 DOI: 10.1007/s40618-020-01225-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Accepted: 03/16/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE To assess outcomes and predictors of early and long-term remission in patients with Cushing's disease (CD) due to ACTH-secreting adenomas treated via endoscopic endonasal approach (EEA). METHODS This is a retrospective study. Consecutive patients operated for CD from 1998 to 2017 in an Italian referral Pituitary Center were enrolled. Clinical, radiological, and histological data at enrollment and follow-up were collected. RESULTS 151 patients (107 F) were included; 88.7% were naïve for treatment, 11.3% had been treated surgically and 11.2% medically. At pre-operative magnetic resonance imaging (MRI), 35 had a macroadenoma and 80 a microadenoma, while tumor was undetectable in 36 patients. Mean age at surgery was 41.1 ± 16.6 years. Diagnosis was confirmed histologically in 82.4% of the cases. Patients with disease persistence underwent second surgery and/or medical and/or radiation therapy. Mean follow-up was 92.3 ± 12.0 (range 12-237.4) and median 88.2 months. Remission rate was 88.1% after the first surgery and 90.7% at last follow-up. One patient died of pituitary carcinoma. Post-surgical cortisol drop (p = 0.004), tumor detection at MRI (p = 0.03) and size < 1 cm (p = 0.045) increased the chance of disease remission; cavernous sinus invasion was a negative predictor of outcome (p = 0.002). Twenty-seven patients developed diabetes insipidus and 18 hypopituitarism. Surgery repetition increased the risk of hypopituitarism (p = 0.03), but not of other complications, which included epistaxis (N = 2), cerebrospinal fluid leakage (1), pneumonia (3), myocardial infarction (1), and pulmonary embolisms (2). CONCLUSIONS Selective adenomectomy via EEA performed by experienced surgeons, supported by a multidisciplinary dedicated team, allows long-term remission in the vast majority of CD patients with low complication rate.

Abstract
OBJECTIVES This study was conducted to investigate complications and outcome by endonasal endoscopic approach in our single center. PATIENTS AND METHODS The clinical data of 2032 pituitary adenoma surgeries performed in our ward between January 2006 and December 2018 were retrospectively reviewed. The GTR (gross total resection) rate, hormonal control, complications, and tumor recurrence rate were retrospectively analyzed. RESULTS There were 628 (83.5 %) preoperative headache patients, 513 (68.9 %) visual acuity and visual field impaired patients, 218 (66.4 %) endocrine symptom patients and 26 (53.1 %) SIADH (syndrome of inappropriate secretion of antidiuretic hormone) patients experienced improvement after surgery. GTR was achieved in 1627 patients (80.1 %) and NGTR (non-gross total resection) in 405 patients (19.9 %). Clinically variable analyses revealed a significant correlation between GTR and Knosp's grades, large tumor volume, bone-invasive and recurrent tumors. Postoperative complications mainly included 34 (1.7 %) CSF (cerebral spinal fluid) leak, 72 (3.5 %) pituitary insufficiency, 30 (1.5 %) meningitis, 20 (0.98 %) cranial nerve deficits, 5 (0.25 %) hematoma, 5 (0.25 %) patients with internal carotid artery injury, and other complications mainly included nasal complications occurred in 168 patients (8.6 %). Overall, there were 3 deaths (0.15 %) occurred in our series. Univariate analysis showed that larger tumors, invasion, bone invasive, recurrent tumors and NGTR were associated with tumor regrowth. Multivariate analysis showed that NGTR and invasion were independent risk factors for tumor regrowth. CONCLUSIONS NGTR and invasion were independent risk factors for tumor regrowth. Endoscopic surgery is an excellent choice for pituitary adenomas. It has the advantages of being minimally invasive, safe, and efficacious.

Abstract
Cushing's disease (CD) is most commonly caused by a microadenoma, which at surgical exploration may not provide adequate tissue for pathologic diagnosis using standard techniques. We wished to determine the accuracy of intraoperative pathologic examination and whether the addition of intraoperative cytology increased the diagnostic yield. We reviewed the pathology reports from 403 operations on 341 patients with CD microadenomas from a single institution. The concordance rates of intraoperative diagnoses (cytology and frozen) with the final (paraffin section) pathological diagnosis were calculated. The overall pathologic confirmation of an adenoma (by either cytology, frozen, or paraffin section) was compared with the result from a historical cohort (using only standard frozen section analysis but not intraoperative cytology) and the pooled result from a meta-analysis of previously published data. The concordance rate between frozen section diagnosis and paraffin section histology was 390/403 (96.8%). The concordance rate between cytological smear and paraffin section histology was 213/246 (86.6%). In 54 cases (13.4%) with ultimate remission, pathologic confirmation was obtained only on intraoperative pathology (frozen section or cytology). Overall, pathologic confirmation was obtained in 326 operations (80.9%) by at least one pathological modality. The overall pathological confirmation of an adenoma was greater after the introduction of intraoperative cytology when compared with the historical control (67.1%, p = 0.015), and compared with the pooled rate of published data from the meta-analysis (72.1%, p < 0.001). Our findings suggest that addition of intraoperative cytological analyses during surgery for CD is an additional useful diagnostic tool for both neurosurgeons and pathologists.

Abstract
Ever since the 1960s, transsphenoidal surgery has been the modality of choice for treating Cushing's disease. Subsequent visualization of the pituitary fossa and sphenoid sinus may be done either with the operating microscope or with the relatively new endoscope. The endoscope due to its panoramic view allows greater visualization as compared to the operating microscope. It confers greater access to the cavernous sinus, sella, suprasellar, and parasellar regions and accommodates higher magnifications. It is bi-dimensional, however as opposed to the operating microscope that provides a three-dimensional view and allows greater depth perception. This article provides a comprehensive review of the advantages and disadvantages of the endoscope and compares it to the operating microscope. We hope this article will prove useful to both clinicians and academicians alike in their approach and management of Cushing's disease.

Abstract
OBJECTIVE Preoperatively determining the extent of parasellar invasion of pituitary macroadenomas is useful for surgical planning and patient counseling. Here, the authors compared constructive interference in steady state (CISS), a T2-weighted gradient-echo MRI sequence, to volume-interpolated breath-hold examination (VIBE), a T1-weighted gradient-echo MRI sequence, for evaluation of cavernous sinus invasion (CSI) by pituitary macroadenomas. METHODS VIBE and CISS images of 98 patients with pituitary macroadenoma were retrospectively analyzed and graded using the modified Knosp classification. The Knosp grades were correlated to surgical findings of CSI, which were determined intraoperatively using 0° and 30° endoscopes. The predictive accuracies for CSI according to the Knosp grades derived from the CISS and VIBE images were compared using receiver operating characteristic (ROC) curves. Postoperative MRI was used to evaluate the gross-total resection (GTR) rates. RESULTS The CSI rate by pituitary macroadenomas was 27.6% (27 of 98 cases). Of 196 assessments (left and right sides of 98 macroadenomas), 45 (23.0%) had different Knosp grades when scored using VIBE versus CISS images. For the VIBE images, 0% of Knosp grade 0, 4.5% of grade 1, 23.8% of grade 2, 42.1% of grade 3A, 100% of grade 3B, and 83.3% of grade 4 macroadenomas were found to have CSI intraoperatively. For the CISS images, 0% of Knosp grade 0, 2.1% of grade 1, 31.3% of grade 2, 56.3% of grade 3A, 100% of grade 3B, and 100% of grade 4 macroadenomas were found to have CSI intraoperatively. Two pituitary macroadenomas were classified as grade 4 on VIBE sequences but grades 3A and 2 on CISS sequences; CSI was not observed intraoperatively in both cases. The GTR rate was 64.3% and 60.0% for high-grade (3A, 3B, and 4) macroadenomas classified using VIBE and CISS sequences, respectively. The areas under the ROC curves were 0.94 and 0.97 for VIBE- and CISS-derived Knosp grades (p = 0.007), respectively. CONCLUSIONS Knosp grades determined using CISS sequence images are better correlated with intraoperative CSI than those determined using VIBE sequence images. CISS sequences may be valuable for the preoperative assessment of pituitary macroadenomas.

Abstract
RATIONALE Knosp grade 4 adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is a rare cause of Cushing disease. After the 1st surgery, the remission rate among these patients is extremely low. PATIENT CONCERNS We presented a case of a 33-year-old female with classical Cushingoid symptoms. Further investigations revealed ATCH-dependent hypercortisolemia, as well as a Knosp grade 4 pituitary macroadenoma. DIAGNOSIS Cushing disease, caused by a Knosp grade 4 pituitary macroadenoma. INTERVENTIONS The patient underwent endoscopic endonasal transsphenoidal surgery with the assistance of intraoperative transsphenoidal Doppler and image-guidance devices. OUTCOMES Pathologic examinations confirmed that the lesion was an ACTH-secreting pituitary adenoma. The patient was in biochemical remission after surgery. Her postoperative magnetic resonance imaging showed gross-total tumor resection. There was no evidence of recurrence during the 1-year follow-up. LESSONS With intraoperative Doppler and image-guidance, gross-total resection and biochemical remission can be achieved in Cushing disease when the internal carotid artery is completely encased by the pituitary adenoma.

Abstract
PURPOSE Systematic review and meta-analysis comparing endoscopic and microscopic transsphenoidal surgery for Cushing's disease regarding surgical outcomes (remission, recurrence, and mortality) and complication rates. To stratify the results by tumor size. METHODS Nine electronic databases were searched in February 2017 to identify potentially relevant articles. Cohort studies assessing surgical outcomes or complication rates after endoscopic or microscopic transsphenoidal surgery for Cushing's disease were eligible. Pooled proportions were reported including 95% confidence intervals. RESULTS We included 97 articles with 6695 patients in total (5711 microscopically and 984 endoscopically operated). Overall, remission was achieved in 5177 patients (80%), with no clear difference between both techniques. Recurrence was around 10% and short term mortality < 0.5% for both techniques. Cerebrospinal fluid leak occurred more often in endoscopic surgery (12.9 vs. 4.0%), whereas transient diabetes insipidus occurred less often (11.3 vs. 21.7%). For microadenomas, results were comparable between both techniques. For macroadenomas, the percentage of patients in remission was higher after endoscopic surgery (76.3 vs. 59.9%), and the percentage recurrence lower after endoscopic surgery (1.5 vs. 17.0%). CONCLUSIONS Endoscopic surgery for patients with Cushing's disease reaches comparable results for microadenomas, and probably better results for macroadenomas than microscopic surgery. This is present despite the presumed learning curve of the newer endoscopic technique, although confounding cannot be excluded. Based on this study, endoscopic surgery may thus be considered the current standard of care. Microscopic surgery can be used based on neurosurgeon's preference. Endocrinologists and neurosurgeons in pituitary centers performing the microscopic technique should at least consider referring Cushing's disease patients with a macroadenoma.

Abstract
PURPOSE Surgical experience is considered paramount for excellent outcome of transsphenoidal surgery (TSS). However, objective data demonstrating the surgical success in relation to the experience of pituitary surgery units or individual experience of pituitary surgeons is sparse. METHODS Based on literature data, we have investigated the influence of experience with TSS for pituitary adenomas on endocrinological remission rates and on operative complications. The surgical experience was assessed by calculating the number of transsphenoidal operations per year. RESULTS For TSS of microprolactinomas, mean remission rates were 77% in centers with < 2 operations per year for microprolactinomas, 82% with 2-4 operations, 84% with 4-6 operations, and 91% with > 6 operations. A yearly experience with more than 10 initial operations for Cushing's disease (CD) warrants a remission rate exceeding 70%. Remission rates in CD exceeding 86% have only been reported for single surgeon series. Extraordinarily high complication rates were found in some series with < 25 yearly total operations for pituitary adenomas. Major vascular complications were less than 2% and revision rates for rhinorrhea usually < 2.5% in centers performing > 25 transsphenoidal operations per year. CONCLUSIONS We conclude that a center with experience of > 25 transsphenoidal operations for pituitary adenomas per year provides a high likelihood of safe TSS. Surgery for CD requires a particularly high level of practice to guarantee excellent remission rates. The endocrinologist has the unique opportunity to audit the surgical success by hormone measurement and to refer patients to neurosurgeons with proven excellence.

Abstract
Abstract
Background: Cushing disease is uncommon challenging disease. The adenomas are usually small in size in most case making the disease diagnosis and management is sometimes difficult. In some cases, the tumor cannot be identified on imaging studies and in many cases the adenoma is eccentric in location adding more difficulties to the trans-sphenoid approach for excision of such tricky tumors.
Object: to evaluate the challenge of diagnosis and trans-sphenoid surgery for ACTH pituitary microadenomas.
Methods: 21 patients with ACTH secreting adenomas were involved in this retrospective study. All cases were operated up on via trans-sphenoid approach during the period from January 2009 till October 2015. All of them were microadenomas. All patients had obvious Cushing manifestations. In all cases magnetic resonance (MR) imaging and CT paranasal sinuses were performed. In this study: cases with macroadenomas and recurrent cases after previous trans-sphenoid approach or gamma knife radiosurgery were excluded.
Results: Among the 21 patients; 14 were female and 7 weremale with age ranging from 21 to 44 years. The imaging study was positive for microadenoma in 18 patients while in 3 cases; no tumor was seen on the MRI imaging. All were operated via the trans-sphenoid approach (12 patients via the microscopic technique and other 9 patients via the endoscopic technique). The adenoma was successfully removed in 15 out of the 18 patients with evident adenoma on pre-operative MRI imaging while partial hypophysectomy were done in 5 cases without an evident adenoma on pre-operative MRI study or difficult adenoma identification. In one patient; the procedure was aborted because of sphenoid sinus abnormalities and the tumor was successfully removed via trans-cranial approach. Disease remission was achieved in 17 patients. In 4 patients; complete remission was not achieved and gamma knife radiosurgery was done after surgery. Disease progression occurred in two patients with initial remission and was treated gamma knife radiosurgery. 13 patients had an ACTH deficiency after surgery while other hormonal replacement therapy is needed in only 5 cases. CSF rhinorrhea occurred in 2 patients and was managed with transient lumbar drain without any subsequent morbidities. Transient diabetes insipidus occurred in 6 cases and was treated conservatively.
Conclusions: The transsphenoidal approach ACTH secreting pituitary microadenomas is considered safe and effective for achieving disease remission despite the challenge of diagnosis and intra-operative tumor identification.

Abstract
INTRODUCTION It is unclear whether the proportions of remission and the recurrence rates differ between endoscopic transsphenoidal surgery (TS) and microscopic TS in Cushing's disease (CD); thus, we conducted a systematic review and meta-analysis to evaluate studies of endoscopic TS and microscopic TS. METHODS We conducted a comprehensive search of PubMed to identify relevant studies. Remission and recurrence were used as outcome measures following surgical treatment of CD. RESULTS A total of 24 cohort studies involving 1670 adult patients were included in the comparison. Among these studies, 702 patients across 9 studies underwent endoscopic TS, and 968 patients across 15 studies underwent microscopic TS. Similar baseline characteristics were observed in both groups. There was no significant difference in remission between the two groups: 79.7% (95% CI: 73.1-85.0%) in the endoscopic group and 76.9% (95% CI: 71.3-81.6%) in the microscopic group (P = 0.485). It appears that patients who underwent endoscopic surgery experience recurrence less often than patients who underwent microscopic surgery, with recurrence proportions of 11.0% and 15.9%, respectively (P = 0.134). However, if follow-up time is taken into account, both groups had a recurrence rate of approximately 4% per person per year (95% CI: 3.1-5.4% and 3.6-5.1%, P = 0.651). CONCLUSIONS We found that remission proportion and recurrence rate were the same in patients who underwent endoscopic TS as in patients who underwent microscopic TS. The definition of diagnosis, remission and recurrence should always be considered in the studies assessing therapeutic efficacy in CD.

World Neurosurg 2016; 96:545-555. [PMID: 27663264 DOI: 10.1016/j.wneu.2016.09.051] [Citation(s) in RCA: 44] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Revised: 09/10/2016] [Accepted: 09/13/2016] [Indexed: 11/25/2022]
Abstract
BACKGROUND The aim of this study is to report the results of pure endoscopic endonasal transsphenoidal surgery (EETSS) for pituitary adenomas (PAs) and to evaluate the efficacy and safety of this procedure. In addition, we tried to determine the predicting factors for progression of PAs. METHODS We reviewed the medical records of 331 consecutive patients who underwent pure EETSS of newly diagnosed PAs between April 1998 and December 2014. Demographic, endocrinologic, and radiologic features and their outcomes, complications, and hospital stay durations were retrospectively assessed in these patients. RESULTS There were 157 (47.4%) nonfunctioning adenomas and 174 (52.6%) hormone-secreting adenomas. Fifty-one (15.4%) complications were present in 39 patients postoperatively. The frequent complications were temporary and permanent diabetes insipidus (14 and 3 cases, respectively), syndrome of inappropriate antidiuretic hormone secretion (9 cases), and cerebrospinal fluid leaks (6 cases). There was only 1 death (0.3%) related to the procedure in this series. The patient's age (P = 0.047), the tumor size (P = 0.003), and the parasellar growth (P <0.001) were associated with the occurrence of complications on multivariate analysis. Progression occurred in 92 (27.8%) patients and the mean time-to-progression was 23.7 months (range, 3.7-52.4 months) after a mean follow-up period of 68.5 months. In the multivariate analysis, the tumor size (P = 0.021), the extent of surgery (P = 0.012), the Knosp classification (P = 0.002), and the MIB-1 index (P = 0.019) were associated with progression-free survival. The mean duration of hospitalization was 4.4 (±1.6) days. CONCLUSIONS The pure EETSS of PA provides acceptable and reasonable results representing a safe alternative procedure to the traditional transsphenoidal microscopic approach.

Abstract
BACKGROUND Transsphenoidal selective adenectomy is considered the treatment of choice in patients with Cushing's disease given the possibility for high remission and low complication rates. The endoscopic endonasal surgical nuances for Cushing's disease are not well illustrated in the neurosurgical technique and video collections. METHODS We describe the technical nuances of microadenoma resection for two cases of Cushing's disease, one in which the adenoma is visualized on imaging and one in which the pre-operative MRI is negative. CONCLUSIONS Transsphenoidal endoscopic selective adenectomy is a safe and effective surgery for patients with Cushing's disease regardless of preoperative MRI findings.

Abstract
BACKGROUND This study was performed to examine patient outcomes following pure endoscopic transsphenoidal surgery (ETS) for Cushing's disease (CD). METHOD We studied 64 consecutive patients who underwent 69 endoscopic transsphenoidal procedures. Radiological evaluation comprised detailed examination of preoperative magnetic resonance images (MRI), including positron emission tomography (PET) for select cases. Inferior petrosal sinus sampling (IPSS) was not performed for any patient. Remission was defined by the presence of hypocortisolemia with requirement for steroid replacement therapy or eucortisolemia with suppression to <1.8 μg/dl after 1 mg dexamethasone on evaluation at least 3 months after surgery. RESULTS Preoperative MRI was abnormal in 87.5 % of cases and included 11 macroadenomas (17.2 %). PET was used to localize the adenoma in four cases. For microadenomas, operative procedures executed were as follows: selective adenomectomy (n = 15), enlarged adenomectomy (n = 21) and subtotal/hemihypophysectomy (n = 17). Overall, pathological confirmation of an adenoma was possible in 58 patients (90.6 %). Forty-nine patients (76.6 %) developed hypocortisolemia (<5 μg/dl) in the early postoperative period. Mean follow-up was 20 months (range 6-18 months). Remission was confirmed in 79.7 % of the 59 cases followed up for >3 months and was superior for microadenomas (86.4 %) versus macroadenomas (55.6 %) and equivocal MRI adenomas (66.7 %). Postoperative CSF rhinorrhea occurred in five patients, and new endocrine deficits were noted in 17.1 % patients. A nadir postoperative cortisol <2 μg/dl in the 1st week after surgery was highly predictive of remission (p = 0.001). CONCLUSION ETS allows for enhanced intrasellar identification of adenomatous tissue, providing remission rates that are comparable to traditional microsurgery for CD. The best predictor of remission remains induction of profound hypocortisolemia in the early postoperative period.

Abstract
OBJECT The purpose of this study was to describe complications associated with the endonasal, transsphenoidal approach for the treatment of adrenocorticotropic hormone (ACTH)-positive staining tumors (Cushing's disease [CD] and silent corticotroph adenomas [SCAs]) performed by 1 surgeon at a high-volume academic medical center. METHODS Medical records from Brigham and Women's Hospital were retrospectively reviewed. Selected for study were 82 patients with CD who during April 2008-April 2014 had consecutively undergone transsphenoidal resection or who had subsequent pathological confirmation of ACTH-positive tumor staining. In addition to demographic, patient, tumor, and surgery characteristics, complications were evaluated. Complications of interest included syndrome of inappropriate antidiuretic hormone secretion, diabetes insipidus (DI), CSF leakage, carotid artery injury, epistaxis, meningitis, and vision changes. RESULTS Of the 82 patients, 68 (82.9%) had CD and 14 (17.1%) had SCAs; 55 patients were female and 27 were male. Most common (n = 62 patients, 82.7%) were microadenomas, followed by macroadenomas (n = 13, 14.7%). A total of 31 (37.8%) patients underwent reoperation. Median follow-up time was 12.0 months (range 3-69 months). The most common diagnosis was ACTH-secreting (n = 68, 82.9%), followed by silent tumors/adenomas (n = 14, 17.1%). ACTH hyperplasia was found in 8 patients (9.8%). Of the 74 patients who had verified tumors, 12 (16.2%) had tumors with atypical features. The overall (CD and SCA) rate of minor complications was 35.4%; the rate of major complications was 8.5% (n = 7). All permanent morbidity was associated with DI (n = 5, 6.1%). In 16 CD patients (23.5%), transient DI developed. Transient DI was more likely to develop in CD patients who had undergone a second operation (37.9%) than in those who had undergone a first operation only (12.8%, p < 0.05). Permanent DI developed in 4 CD patients (5.9%) and 1 SCA patient (7.1%). For 1 CD patient, intraoperative carotid artery injury required endovascular sacrifice of the injured artery, but the patient remained neurologically intact. For another CD patient, aseptic meningitis developed and was treated effectively with corticosteroids. One CD patient experienced major postoperative epistaxis requiring another operative procedure to achieve hemostasis. For 2 CD patients, development of sinus mucoceles was managed conservatively. For 1 SCA patient, an abdominal wound dehisced at the fat graft site. No patients experienced postoperative CSF leakage, visual impairment, or deep vein thrombosis. CONCLUSIONS Transsphenoidal surgery is the treatment of choice for patients with CD and other ACTH-positive staining tumors. Recent advances in endoscopic technology and increasing surgeon comfort with this technology are making transsphenoidal procedures safer, faster, and more effective. Serious complications are uncommon and can be managed successfully.

Abstract
OBJECTIVE The objective of this study was to report the efficacy, safety, and outcomes of endoscopic endonasal transsphenoidal techniques for pituitary adenomas. PATIENTS AND METHODS A retrospective data analysis of 32 patients who underwent endoscopic endonasal transsphenoidal surgery for pituitary adenoma between February 2011 and December 2013 was performed. The patients' demographic data, clinical presentations, radiologic findings, recurrence rates, and complications were analyzed. RESULTS There were 14 men and 18 women with age ranging from 23 to 74 years (mean age, 48.6 y). Functioning and nonfunctioning tumors were present in 22 (68.8%) and 10 patients (31.2%), respectively. Among the functioning adenomas, 8 patients (25%) had growth hormone-secreting adenomas, 6 patients (18.8%) had prolactinomas, 5 patients (15.6%) had adrenocorticotropic hormone-secreting adenomas, 2 patients (6.2%) had follicle-stimulating hormone/luteinizing hormone-secreting adenomas, and 1 patient (3.1%) had thyroid-stimulating hormone-secreting adenomas. Of the 32 patients, 20 (62.5%) had pituitary macroadenomas and 12 patients (37.5%) had microadenomas. Total-subtotal tumor resection was achieved in 75% and 45% of the microadenomas and macroadenomas, respectively. Radiologically, 60% of the macroadenomas had suprasellar and carvenous sinus extension. Postoperative cerebrospinal fluid leaks occurred in 3 patients. Two patients developed temporary diabetes insipidus. CONCLUSIONS Endoscopic transsphenoidal surgery is an effective and safe treatment for most patients with pituitary adenoma and could be considered the first-choice therapy in these patients.

Abstract
OBJECTIVE The purpose of this study was to analyze the outcomes and complications of the endoscopic endonasal approach (EEA) performed on patients with Cushing disease at our Pituitary Center during the past 11 years. METHODS Clinical information and imaging in electronic medical records were reviewed for patients who underwent EEA. Statistical analysis was performed with χ2 testing and Student's t-test. RESULTS Remission was achieved in 39 patients (79.6%) at initial evaluation within 2 weeks of surgery. At last follow-up, remission persisted in 70% of 50 patients with EEA alone (mean follow-up time, 37.5 ± 4.6 months; median, 26.2 months; range, 2.5-155.0 months). At last follow-up, remission rates were 80% among magnetic resonance imaging-negative adenomas, 70.6% among noninvasive or minimally invasive adenomas (Knosp 0, 1, 2), and 50% among invasive adenomas (Knosp 3, 4). There were no statistical differences in the remission rates among these categories (P = 0.444). Women had higher proportions of initial remission than men (P = 0.033) and patients who had no initial remission were older (P = 0.046). Higher preoperative normalized adrenocroticotropic hormone level was associated with a greater degree of invasiveness (P = 0.021). However, there was no association between preoperative normalized urine-free cortisol levels and degree of invasiveness (P = 0.582). Complications included panhypopituitarism (n = 3), hypothyroidism (n = 3), growth hormone deficiency (n = 1), hypogonadism (n = 1), postoperative cerebrospinal fluid leak (n = 2), and transient diabetes insipidus (n = 4). CONCLUSIONS The EEA for Cushing disease resulted in remission and complication rates comparable with previous analyses of EEA, as well as microsurgical series. Preoperative adrenocorticotropic hormone levels were associated with invasiveness.

Abstract
Cushing's disease (CD), or pituitary-dependent Cushing's syndrome, is a severe endocrine disease caused by a corticotroph pituitary tumor and associated with increased morbidity and mortality. The first-line treatment for CD is pituitary surgery, which is followed by disease remission in around 78% and relapse in around 13% of patients during the 10-year period after surgery, so that nearly one third of patients experience in the long-term a failure of surgery and require an additional second-line treatment. Patients with persistent or recurrent CD require additional treatments, including pituitary radiotherapy, adrenal surgery, and/or medical therapy. Pituitary radiotherapy is effective in controlling cortisol excess in a large percentage of patients, but it is associated with a considerable risk of hypopituitarism. Adrenal surgery is followed by a rapid and definitive control of cortisol excess in nearly all patients, but it induces adrenal insufficiency. Medical therapy has recently acquired a more important role compared to the past, due to the recent employment of novel compounds able to control cortisol secretion or action. Currently, medical therapy is used as a presurgical treatment, particularly for severe disease; or as postsurgical treatment, in cases of failure or incomplete surgical tumor resection; or as bridging therapy before, during, and after radiotherapy while waiting for disease control; or, in selected cases, as primary therapy, mainly when surgery is not an option. The adrenal-directed drug ketoconazole is the most commonly used drug, mainly because of its rapid action, whereas the glucocorticoid receptor antagonist, mifepristone, is highly effective in controlling clinical comorbidities, mainly glucose intolerance, thus being a useful treatment for CD when it is associated with diabetes mellitus. Pituitary-directed drugs have the advantage of acting at the site responsible for CD, the pituitary tumor. Among this group of drugs, the dopamine agonist cabergoline and the somatostatin analog pasireotide result in disease remission in a consistent subgroup of patients with CD. Recently, pasireotide has been approved for the treatment of CD when surgery has failed or when surgery is not an option, and mifepristone has been approved for the treatment of Cushing's syndrome when associated with impairment of glucose metabolism in case of the lack of a surgical indication. Recent experience suggests that the combination of different drugs may be able to control cortisol excess in a great majority of patients with CD.

Abstract
Introduçáo A cirurgia endoscópica endonasal ganhou aceitação crescente por otorrinolaringologistas e neurocirurgiões. Em muitos centros, esta tecnica é agora rotineiramente utilizada para as mesmas indicações que a técnica microcirúrgica convencional. Objetivo Descrever resultados cirúrgicos relativos à remissão hormonal, ressecção do tumor e complicações de série consecutiva de pacientes com adenoma da hipófise submetidos à ressecção endoscópica. Método Estudo de série de pacientes consecutivos com adenomas da hipófise, submetidos à cirurgia endoscópica endonasal, avaliados quanto à taxa de tumor residual, remissão funcional, sintomas, complicações e o tamanho do tumor. Resultados De 47 pacientes consecutivos, 17 eram portadores de adenomas funcionantes, sete produtores de GH, cinco com doença de Cushing e cinco prolactinomas. Dos adenomas funcionantes, 12 foram macroadenomas, cinco microadenomas, e 30 macroadenomas não funcionantes. Dos adenomas funcionantes, 87% melhoraram. Em relação ao déficit visual, 85% melhoraram ao longo do tempo. A maioria dos pacientes que apresentou queixas de cefaléia melhorou (76%). Complicações cirúrgicas ocorreram em 10% dos pacientes, com duas lesões da carótida, duas fístulas liquóricas e uma fatalidade em um paciente com um histórico complicado. Conclusão A cirurgia hipofisária endoscópica endonasal é uma técnica viável, rendendo bons resultados cirúrgicos e funcionais e baixa morbidade. © 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Abstract
High levels of endogenous cortisol due to Cushing's disease cause significant mortality and morbidity. Treatment of Cushing's disease is challenging. For many years, transsphenoidal microsurgical resection of the adenoma has been the treatment of choice. However, recently, neuroendoscope has taken its place in the neurosurgeon's armamentarium, and the endoscopic transsphenoidal resection of pituitary tumors has become a familiar approach. Our aim was to present the results of pure endoscopic surgery in the treatment of corticotropinomas for comparison with the results of previous endoscopic and microsurgical series. We present a retrospective analysis of 90 patients with diagnosis of Cushing's disease who were operated between 2006 and 2012. Among 90 patients, a total of 81 (90.0 %) had a remission (28 out of 29 macroadenomas (96.6 %) and 53 out of 61 microadenoma patients (86.9 %)). Of note is that 66 out of 69 (95.7 %) primary patients (i.e., those who were operated in our center) and 15 out of 21 (71.4 %) patients previously operated in other centers reached a hypo/eucortisolemic state. A remission rate comparable with previous endoscopic series was achieved. In nine patients, it was not possible to achieve remission at all. On the other hand, only four of our cases (5.6 %) had a recurrence, and with reoperation, all of these patients entered a re-remission. To our knowledge, our series is the largest series studying endoscopically operated adrenocorticotropic hormone-secreting adenomas. Our results suggest that the endoscopic approach has opened a new avenue in the treatment of Cushing's disease, previously a therapeutic challenge for both the clinician and the neurosurgeon. Endoscopic approach in the treatment of Cushing's disease is clearly better for patients because of its low morbidity rates and short duration of hospital stay. On the other hand, long-term follow-up of our patients will show whether these favorable observations will persist.

Abstract
Object
Endoscopic transsphenoidal surgery is expanding in acceptance, yet postoperative CSF leak rates remain a concern. This study presents the Cornell closure protocol, which has yielded significantly lower postoperative CSF leak rates compared with prior reports, as an algorithm that can be used by centers having difficulty with CSF leak.
Methods
A single closure algorithm for endoscopic surgery has been used since January 2010 at Weill Cornell Medical College. A prospective database noting intraoperative CSF leak, closure technique, and postoperative CSF leak was reviewed. The authors used a MEDLINE search to identify similar studies and compared CSF leak rates to those of patients treated using the Cornell algorithm.
Results
The retrospective study of a prospectively acquired database included 209 consecutive patients. In 84 patients (40%) there was no intraoperative CSF leak and no postoperative CSF leak. In the 125 patients (60%) with an intraoperative CSF leak, 35 of them with high-flow leaks, there were 0 (0%) postoperative CSF leaks.
Conclusions
It is possible to achieve a CSF leak rate of 0% by using this closure protocol. With proper experience, endoscopic skull base surgery should not be considered to have a higher CSF leak rate than open transcranial or microscopic transsphenoidal surgery.

Abstract
BACKGROUND Over the past decade, the endoscopic endonasal trans-sphenoidal approach has been used to resect pituitary adenomas. However, in the use of this procedure, some research teams prefer a two-nostril method, whereas other groups are in favor of the one-nostril method. Here, we present a series of pituitary adenomas and try to confirm whether or not one nostril is enough for endoscopic resection of most pituitary adenomas. METHODS A total of 250 consecutive patients who underwent an endoscopic endonasal trans-sphenoidal approach were reviewed retrospectively, of which 200 were via the unilateral nostril (group 1) and 50 were via bilateral nostrils (group 2). Surgical and clinical outcomes were analyzed. RESULTS For microadenomas, intrasellar macroadenomas and macroadenomas with moderate extrasellar extension, the prevalence of gross total resection (GTR), hormonal outcome and visual improvement were similar between the two groups. The one-nostril group had better results for duration of surgery and blood loss, with fewer rhinological complications. However, for macroadenomas with extensive extrasellar invasion, GTR was obtained in two of seven patients in group 2 but none in group 1. CONCLUSION The one-nostril method, which is relatively fast and minimally invasive, is adequate for endoscopic resection of most pituitary adenomas with moderate extension.

Abstract
OBJECT Endoscopy as a visual aid (endoscope assisted) or as the sole visual method (fully endoscopic) is increasingly used in pituitary adenoma surgery. Authors of this study assessed the value of endoscopic visualization for finding and removing residual adenoma after initial microscopic removal. METHODS Consecutive patients who underwent endoscope-assisted microsurgical removal of pituitary adenoma were included in this study. The utility of the endoscope in finding and removing residual adenoma not visualized by the microscope was noted intraoperatively. After maximal tumor removal under microscopic visualization, surgeries were categorized as to whether additional tumor was removed via endoscopy. Tumor removal and remission rates were also noted. Patients undergoing fully endoscopic tumor removal during this same period were excluded from the study. RESULTS Over 3 years, 140 patients (41% women, mean age 50 years) underwent endoscope-assisted adenoma removal of 30 endocrine-active microadenomas and 110 macroadenomas (39 endocrine-active, 71 endocrine-inactive); 16% (23/140) of patients had prior surgery. After initial microscopic removal, endoscopy revealed residual tumor in 40% (56/140) of cases and the additional tumor was removed in 36% (50 cases) of these cases. Endoscopy facilitated additional tumor removal in 54% (36/67) of the adenomas measuring ≥ 2 cm in diameter and in 19% (14/73) of the adenomas smaller than 2 cm in diameter (p < 0.0001); additional tumor removal was achieved in 20% (6/30) of the microadenomas. Residual tumor was typically removed from the suprasellar extension and folds of the collapsed diaphragma sellae or along or within the medial cavernous sinus. Overall, 91% of endocrine-inactive tumors were gross-totally or near-totally removed, and 70% of endocrine-active adenomas had early remission. CONCLUSIONS After microscope-based tumor removal, endoscopic visualization led to additional adenoma removal in over one-third of patients. The panoramic visualization of the endoscope appears to facilitate more complete tumor removal than is possible with the microscope alone. These findings further emphasize the utility of endoscopic visualization in pituitary adenoma surgery. Longer follow-ups and additional case series are needed to determine if endoscopic adenomectomy translates into higher long-term remission rates.

Abstract
Endoscopic endonasal trans-sphenoid surgery (EETS) is increasingly used for pituitary lesions. Pre-operative CT and MRI scans and peroperative endoscopic visualization can provide useful anatomical information. EETS is indicated in sellar, suprasellar, intraventricular, retro-infundibular, and invasive tumors. Recurrent and residual lesions, pituitary apoplexy and empty sella syndrome can be managed by EETS. Modern neuronavigation techniques, ultrasonic aspirators, ultrasonic bone curette can add to the safety. The binostril approach provides a wider working area. High definition camera is much superior to three-chip camera. Most of the recent reports favor EETS in terms of safety, quality of life and tumor resection, hospital stay, better endocrinological, and visual outcome as compared to the microscopic technique. Nasal symptoms, blood loss, operating time are less in EETS. Various naso-septal flaps and other techniques of CSF leak repair could help reduce complications. Complications can be further reduced after achieving the learning curve, good understanding of limitations with proper patient selection. Use of neuronavigation, proper post-operative care of endocrine function, establishing pituitary center of excellence and more focused residency and endoscopic fellowship training could improve results. The faster and safe transition from microscopic to EETS can be done by the team concept of neurosurgeon/otolaryngologist, attending hands on cadaveric dissection, practice on models, and observation of live surgeries. Conversion to a microscopic or endoscopic-assisted approach may be required in selected patients. Multi-modality treatment could be required in giant and invasive tumors. EETS appears to be a better surgical option in most pituitary adenoma.

Abstract
OBJECTIVE The nature of the pituitary adenomas itself exposes the possibility of a recurrence of the tumor. The aim of this study was to evaluate the effectiveness of the endoscopic endonasal transsphenoidal approach for the removal of recurrent and residual pituitary adenomas, already treated by a microscopic or endoscopic transsphenoidal approach or by a transcranial route. METHODS A total of 59 adult patients with a recurrent or regrowing pituitary adenoma underwent surgery using a pure endoscopic endonasal transsphenoidal approach. Of these patients, 31 were previously operated on by a microsurgical transsphenoidal approach, 22 by means of an endoscopic transsphenoidal route, and 6 via a transcranial route. The patient series has been divided into 3 tiers according to the primary surgery, and the results were evaluated accordingly. RESULTS Gross total removal was achieved in 37 of our cases (62.7%). According to prior surgery at primary disease, we found that in the subgroup of patients who underwent a microsurgical transsphenoidal approach we achieved gross total removal in 23 cases (74.2%; 23 of 31), whereas in the group of patients who underwent the endoscopic endonasal approach, gross total removal was attained respectively in 13 cases (59.1%; 13 of 22) and in only 1 case of those who underwent the transcranial approach (16.7%; 1 of 6). Postoperative complications included 1 case (1.7%) of cerebrospinal fluid leak and meningitis, and 1 with an hematoma in the tumor field (1.7%); both needed surgical reoperation. CONCLUSIONS The endoscopic endonasal approach is a safe and effective procedure for the management of recurrent and/or regrowing pituitary tumors previously treated by either a microsurgical or an endoscopic approach.

Abstract
Abstract
Pituitary tumors and associated neuroendocrine disorders pose significant challenges in diagnostic and therapeutic management. Optimal care of the “pituitary patient” is best provided in a multidisciplinary collaborative environment that includes not only experienced pituitary practitioners in neurosurgery and endocrinology, but also in otorhinolaryngological surgery, radiation oncology, medical oncology, neuro-ophthalmology, diagnostic and interventional neuroradiology, and neuropathology. We provide the background and rationale for recognizing pituitary centers of excellence and suggest a voluntary verification process, similar to that used by the American College of Surgeons for Trauma Center verification. We propose that pituitary centers of excellence should fulfill 3 key missions: (1) provide comprehensive care and support to patients with pituitary disorders; (2) provide residency training, fellowship training, and/or continuing medical education in the management of pituitary and neuroendocrine disease; and (3) contribute to research in pituitary disorders. As this is a preliminary proposal, we recognize several issues that warrant further consideration including center and surgeon practice volume as well as oversight of the verification process.

Abstract
BACKGROUND Endoscopic transsphenoidal surgery has been shown to be a safe and effective treatment option for patients with pituitary tumours, but no study has explored patients' perceptions before and after this surgery. OBJECTIVE The authors in this study aim to explore patients' perceptions on endoscopic transsphenoidal surgery. METHODS Using qualitative research methodology, two semi-structured interviews were conducted with 30 participants who were adults aged > 18 undergoing endoscopic transsphenoidal surgery for the resection of a pituitary tumour between December 2008 and June 2011. The interviews were audiotaped and transcribed. The resulting data was analyzed using a modified thematic analysis. RESULTS Seven overarching themes were identified: (1) Patients had a positive surgical experience; (2) patients were satisfied with the results of the procedure; (3) patients were initially surprised that neurosurgery could be performed endonasally; (4) patients expected a cure and to feel better after the surgery; (5) many patients feared that something might go wrong during the surgery; (6) patients were psychologically prepared for the surgery; (7) most patients reported receiving adequate pre-op and post-op information. CONCLUSIONS This is the first qualitative study reporting on patients' perceptions before and after an endoscopic endonasal transsphenoidal pituitary surgery, which is increasingly used as a standard surgical approach for patients with pituitary tumours. Patients report a positive perception and general satisfaction with the endoscopic transsphenoidal surgical experience. However, there is still room for improvement in post-surgical care. Overall, patients' perceptions can help improve the delivery of comprehensive care to future patients undergoing pituitary tumour surgery.

Abstract
BACKGROUND The surgical approaches for clival chordomas remain controversial, although the extent of resection is one of the most important factors for long survival rates. Recently an endoscopic endonasal approach in good collaboration with otolaryngologists has attracted major attention as a surgical approach for clival chordomas. We describe our experience with the endoscopic endonasal approach and provide a review of the literature. METHODS Between 2008 and 2011, six operations were performed via the endoscopic endonasal approach for clivus chordomas. The mean tumor size was 35 mm in diameter. The tumor location was mainly from the upper to middle clivus. The tumor extended into the cavernous sinus in five cases and intradurally in three cases. A binostril approach was performed in four cases, while a one nostril approach was performed in two cases. RESULTS Gross total removal was achieved in three cases. The analysis of cases with incomplete resection suggested that residual tumors were observed epidurally and subdurally. The residual on the epidura was observed from the posterior clinoid to the posterior compartment of the cavernous sinus. On the other hand, the residual on the subdural was observed behind the upper part of the pituitary gland. There was no postoperative cerebrospinal fluid (CSF) leakage using vascularized nasoseptal flaps in any of the cases. CONCLUSIONS The endoscopic endonasal transclival approach allows an appropriate extent of resection with acceptable complication rates in comparison with other approaches. In our series, the accomplishment of gross total removal was associated with the relationship between the tumors and surrounding structures, such as the pituitary gland and the cavernous portion of the intracranial carotid artery (ICA).

Abstract
The authors investigate the complications of transnasal transsphenoidal endoscopic surgery in the treatment of 301 patients with pituitary adenomas. A retrospective analysis of complications in 301 patients submitted to transsphenoidal transnasal endoscopic surgery at the General Hospital of Fortaleza, Brazil between January 1998 and December 2009. The complications were divided in two groups: anatomical (oronasofacial, sphenoid sinus, intrasellar, suprasellar and parasellar) and endocrinological complications (anterior and posterior pituitary dysfunctions). We observed a total of 81 complications (26.9%) in our series. Anatomical complications occurred in 8.97% (27 cases): 8 CSF postoperative leaks (2.6%), 6 cases (1.9%) of delayed nasal bleeding, 5 cases (1.6%) of sphenoidal sinusitis, 3 cases (0.9%) of carotid artery lesion, 2 cases of meningitis (0.6%) and one case (0.3%) of each of the uncommon following complications: intrasella-suprasella hematoma, pontine hematoma and chiasmaplexy. Endocrinological complications occurred in 17.9% (54 cases): additional postoperative anterior lobe insufficiency in 35 cases (11.6%), and postoperative diabetes insipidus in 19 cases (6.3%). In our series, 3 cases of deaths (not directly related to the procedure) were also observed. Endoscopic transsphenoidal surgery represents an effective option for the treatment of patients with pituitary tumor. Complications still occur and must be reduced as much as possible. Successful endoscopic pituitary surgery requires extensive training in the use of an endoscope and careful planning of the surgery. Additional improvement can be expected with greater experience and new technical developments.

Abstract
Cushing disease is caused by a corticotroph tumor of the pituitary gland. Patients with Cushing disease are usually treated with transsphenoidal surgery, as this approach leads to remission in 70-90% of cases and is associated with low morbidity when performed by experienced pituitary gland surgeons. Nonetheless, among patients in postoperative remission, the risk of recurrence of Cushing disease could reach 20-25% at 10 years after surgery. Patients with persistent or recurrent Cushing disease might, therefore, benefit from a second pituitary operation (which leads to remission in 50-70% of cases), radiation therapy to the pituitary gland or bilateral adrenalectomy. Remission after radiation therapy occurs in ∼85% of patients with Cushing disease after a considerable latency period. Interim medical therapy is generally advisable after patients receive radiation therapy because of the long latency period. Bilateral adrenalectomy might be considered in patients who do not improve following transsphenoidal surgery, particularly patients who are very ill and require rapid control of hypercortisolism, or those wishing to avoid the risk of hypopituitarism associated with radiation therapy. Adrenalectomized patients require lifelong adrenal hormone replacement and are at risk of Nelson syndrome. The development of medical therapies with improved efficacy might influence the management of this challenging condition.

Abstract
Object
In this report, the authors describe their experience with surgical access to the cavernous sinus via a fully transnasal endoscopic approach in 20 cases. Clinical and endocrinological follow-up are discussed.
Methods
The authors used an endoscopic transsphenoidal approach in 192 patients with pituitary adenomas between September 1997 and January 2008, adding a cavernous sinus approach in 20 patients with invasive tumors during the last 5 years of this period. Parasellar extension of the tumor was measured according to the Knosp Scale. Radical tumor removal was achieved in 13 (65%) of 20 patients, and subtotal removal in 7 (35%). The authors used recently defined cavernous sinus approaches in the first 14 cases, including the paraseptal approach in 6, middle turbinectomy in 7, and contralateral middle turbinectomy in 1 case. Combined approaches rather than defined standard cavernous sinus approaches were used in 4 cases and an extended approach in 2.
Results
The tumors included nonsecretory adenomas in 5 cases (25%), growth hormone–secreting adenomas in 7 (35%), prolactin-secreting adenomas in 4 (20%), and adrenocorticotropic hormone–secreting adenomas in 4 cases (20%). Normal growth hormone and insulin-like growth factor 1 levels were achieved in 4 patients (57%) with growth hormone adenomas, and remission criteria were obtained in 3 patients with prolactinomas and 3 patients with adrenocorticotropic hormone–secreting adenomas.
Conclusions
Compared with transcranial and microscopic transsphenoidal surgery, endoscopic transsphenoidal surgery offers a wide exposure for cavernous sinus medial wall adenomas that enables removal of the adenoma from the medial cavernous sinus wall. Because of the necessity for multidisciplinary treatment to achieve satisfactory results, Gamma Knife surgery and medical therapy should be supplementary treatment options after endoscopic transsphenoidal surgery.

Abstract
OBJECT Clival lesions pose significant challenges with regard to their surgical management. The expanded endoscopic endonasal (EEE) approach is a promising minimally invasive technique for lesions of the central skull base. The authors' aim in the current paper was to discuss the surgical treatment of clival lesions and to present the technical details, indications, and limitations of the EEE approach. Data from a recent endoscopically treated group will be compared with findings in a previous cohort of patients treated via classic open anterior and lateral approaches. METHODS Since June 2005, 17 patients with clival lesions underwent surgery via the EEE approach. Suitable candidates were chosen according to lesion characteristics, clinical parameters, and surgical goals. Neurological outcomes, Karnofsky Performance Scale scores, the extent of lesion resection, and complications were evaluated among these patients. Eighteen percent of the patients in the endoscopic group presented with recurrent disease. Another series of 43 patients, who had undergone resection of clival lesions via an anterior (rhinotomy, maxillectomy, microscopic transsphenoidal surgery, or transoral surgery) or lateral (pterional, frontoorbitozygomatic, or combined suprainfratentorial retrosigmoid) approach, was similarly reviewed. Twenty-three of these patients (53%) presented with recurrent disease and thus had undergone prior surgery. RESULTS Following the EEE approach, 11 (79%) of 14 patients who had presented with neurological symptoms experienced improvement, and gross-total resection was achieved in 59% of the patients and subtotal removal in 41%. Complications included CSF leakage (24%), tension pneumocephalus (6%), and intracranial hematoma (6%). The patient with the latter complication was the only one who experienced permanent neurological worsening. In the open resection group, neurological worsening occurred in 33% of the patients (14 of 43). Total and grosstotal removals were achieved in 84% of patients and subtotal removal in 14%. CONCLUSIONS The EEE approach has been shown to be a safe and effective technique for the resection of clival lesions with limited lateral extension. The choice of surgical approach must be tailored according to both patient and tumor characteristics. Although the 2 patient series featured in this paper are not comparable-because of a selection bias-higher rates of neurological morbidity and total and gross-total resections were observed in the open resection group. Given the long survival of some patients, the EEE approach should be favored whenever reasonable.
