Abstract
The vital physiological role of the pituitary gland, alongside its proximity to critical neurovascular structures, means that pituitary adenomas can cause significant morbidity or mortality. While enormous advancements have been made in the surgical care of pituitary adenomas, numerous challenges remain, such as treatment failure and recurrence. To meet these clinical challenges, there has been an enormous expansion of novel medical technologies (eg, endoscopy, advanced imaging, artificial intelligence). These innovations have the potential to benefit each step of the patient's journey, and ultimately, drive improved outcomes. Earlier and more accurate diagnosis addresses this in part. Analysis of novel patient data sets, such as automated facial analysis or natural language processing of medical records holds potential in achieving an earlier diagnosis. After diagnosis, treatment decision-making and planning will benefit from radiomics and multimodal machine learning models. Surgical safety and effectiveness will be transformed by smart simulation methods for trainees. Next-generation imaging techniques and augmented reality will enhance surgical planning and intraoperative navigation. Similarly, surgical abilities will be augmented by the future operative armamentarium, including advanced optical devices, smart instruments, and surgical robotics. Intraoperative support to surgical team members will benefit from a data science approach, utilizing machine learning analysis of operative videos to improve patient safety and orientate team members to a common workflow. Postoperatively, neural networks leveraging multimodal datasets will allow early detection of individuals at risk of complications and assist in the prediction of treatment failure, thus supporting patient-specific discharge and monitoring protocols. While these advancements in pituitary surgery hold promise to enhance the quality of care, clinicians must be the gatekeepers of the translation of such technologies, ensuring systematic assessment of risk and benefit prior to clinical implementation. In doing so, the synergy between these innovations can be leveraged to drive improved outcomes for patients of the future.

Defining benchmark outcomes for transsphenoidal surgery of pituitary adenomas: a multicenter analysis. Eur J Endocrinol 2023; 189:379-386. [PMID: 37668325 DOI: 10.1093/ejendo/lvad124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 07/14/2023] [Accepted: 08/01/2023] [Indexed: 09/06/2023]
Abstract
IMPORTANCE Benchmarks aid in improve outcomes for surgical procedures. However, best achievable results that have been validated internationally for transsphenoidal surgery (TS) are not available. OBJECTIVE We aimed to establish standardized outcome benchmarks for TS of pituitary adenomas. DESIGN A total of 2685 transsphenoidal tumor resections from 9 expert centers in 3 continents were analyzed. SETTING Patients were risk stratified, and the median values of each center's outcomes were established. The benchmark was defined as the 75th percentile of all median values for a particular outcome. The postoperative benchmark outcomes included surgical factors, endocrinology-specific values, and neurology-specific values. RESULTS Of 2685 patients, 1149 (42.8%) defined the low-risk benchmark cohort. Within these benchmark cases, 831 (72.3%) patients underwent microscopic TS, and 308 (26.8%) patients underwent endoscopic endonasal resection. Of all tumors, 799 (29.8%) cases invaded the cavernous sinus. The postoperative complication rate was 19.6% with mortality between 0.0% and 0.8%. Benchmark cutoffs were ≤2.9% for reoperation rate, ≤1.9% for cerebrospinal fluid leak requiring intervention, and ≤15.5% for transient diabetes insipidus. At 6 months, benchmark cutoffs were calculated as follows: readmission rate: ≤6.9%, new hypopituitarism ≤6.0%, and tumor remnant ≤19.2%. CONCLUSIONS This analysis defines benchmark values for TS targeting morbidity and mortality and represents the best outcomes in the best patients in expert centers. These cutoffs can be used to assess different centers, patient populations, and novel surgical techniques. It should be noted that the benchmark values may influence each other and must be evaluated in their own context.

Abstract
Acromegaly is a rare and insidious disease characterized by chronic excess growth hormone, leading to various morphological changes and systemic complications. Despite its low prevalence, acromegaly poses a significant socioeconomic burden on patients and healthcare systems. This review synthesizes the current state of knowledge on the psychosocial burden, disability, impact on daily life, and cost of acromegaly disease, focusing on the quality of life, partnership, medical care and treatment afflictions, participation in daily activities, professional and leisure impairment, and cost of treatment for acromegaly and its comorbidities. It also examines management strategies, coping mechanisms, and interventions aimed at alleviating this burden. A comprehensive understanding of the extent of the socioeconomic burden in acromegaly is crucial to develop effective strategies to improve treatment and care. Further research is warranted to explore the myriad factors contributing to this burden, as well as the efficacy of interventions to alleviate it, ultimately enhancing the quality of life for patients with acromegaly.

The volume-outcome relationship for endoscopic transsphenoidal pituitary surgery for benign neoplasm: analysis of an administrative dataset for England. Br J Neurosurg 2023:1-8. [PMID: 36740733 DOI: 10.1080/02688697.2023.2175783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 01/23/2023] [Accepted: 01/28/2023] [Indexed: 02/07/2023]
Abstract
BACKGROUND Setting minimum annual volume thresholds for pituitary surgery in England is seen as one way of improving outcomes for patients and service efficiency. However, there are few recent studies from the UK on whether a volume-outcome effect exists, particularly in the era of endoscopic surgery. Such data are needed to allow evidence-based decision making. The aim of this study was to use administrative data to investigate volume-outcome effects for endoscopic transsphenoidal pituitary surgery in England. METHODS Data from the Hospital Episodes Statistics database for adult endoscopic transsphenoidal pituitary surgery for benign neoplasm conducted in England from April 2013 to March 2019 (inclusive) were extracted. Annual surgeon and trust volume was defined as the number of procedures conducted in the 12 months prior to the index procedure. Volume was categorised as < 10, 10-19, 20-29, 30-39 and ≥40 procedures for surgeon volume and < 20, 20-39, 40-59, 60-79 and ≥80 procedures for trust volume. The primary outcome was repeat ETSPS during the index procedure or during a hospital admission within one-year of discharge from the index procedure. RESULTS Data were available for 4590 endoscopic transsphenoidal pituitary procedures. After adjustment for covariates, higher surgeon volume was significantly associated with reduced risk of repeat surgery within one year (odds ratio (OR) 0.991 (95% confidence interval (CI) 0.982-1.000)), post-procedural haemorrhage (OR 0.977 (95% CI 0.967-0.987)) and length of stay greater than the median (0.716 (0.597-0.859)). A higher trust volume was associated with reduced risk of post-procedural haemorrhage (OR 0.992 (95% CI 0.985-0.999)), but with none of the other patient outcomes studied. CONCLUSIONS A surgeon volume-outcome relationship exists for endoscopic transsphenoidal pituitary surgery in England.

Abstract
Measure something, and it gets better-this is what is called as the Hawthorne effect (also known as the observer effect). The Hawthorne factory experiments in 1920s were remarkable industrial data collection and analysis exercises that lead to Edwards Deming's quality revolution. The Harvard Medical Practice Study (1991), Leape's "Error in Medicine" (1994), and the Bristol pediatric cardiac report (2001) are among many documents that have revealed the huge gap between best practices and actual medical practice. Alarmed by the poor standards of quality at the most respected institutions, the medical fraternity therefore began visiting facilities in different fields and observing their quality assessment processes. The next leap for neurosurgery is to realize that it is unacceptable to treat patients with no regard for the standard of clinical outcomes. The traditional neurosurgery residency training has long ignored the most important issues of self-assessment, reappraisal, relearning, and measurement of skill and surgical outcomes. However, the experience taken from disparate fields, especially cardiac surgery, may encourage research and progress in measurement and improvement of quality in neurosurgery. Like cardiac surgeons, neurosurgeons must examine and analyze the results of their interventions. The concept of quality measurement is the most important single advance we can make in neurosurgery practice. Meticulous and precise measurement of outcomes will allow future progress of our specialty.

Abstract
PURPOSE Acute pituitary referrals to neurosurgical services frequently necessitate emergency care. Yet, a detailed characterisation of pituitary emergency referral patterns, including how they may change prospectively is lacking. This study aims to evaluate historical and current pituitary referral patterns and utilise state-of-the-art machine learning tools to predict future service use. METHODS A data-driven analysis was performed using all available electronic neurosurgical referrals (2014-2021) to the busiest U.K. pituitary centre. Pituitary referrals were characterised and volumes were predicted using an auto-regressive moving average model with a preceding seasonal and trend decomposition using Loess step (STL-ARIMA), compared against a Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM) algorithm, Prophet and two standard baseline forecasting models. Median absolute, and median percentage error scoring metrics with cross-validation were employed to evaluate algorithm performance. RESULTS 462 of 36,224 emergency referrals were included (referring centres = 48; mean patient age = 56.7 years, female:male = 0.49:0.51). Emergency medicine and endocrinology accounted for the majority of referrals (67%). The most common presentations were headache (47%) and visual field deficits (32%). Lesions mainly comprised tumours or haemorrhage (85%) and involved the pituitary gland or fossa (70%). The STL-ARIMA pipeline outperformed CNN-LSTM, Prophet and baseline algorithms across scoring metrics, with standard accuracy being achieved for yearly predictions. Referral volumes significantly increased from the start of data collection with future projected increases (p < 0.001) and did not significantly reduce during the COVID-19 pandemic. CONCLUSION This work is the first to employ large-scale data and machine learning to describe and predict acute pituitary referral volumes, estimate future service demands, explore the impact of system stressors (e.g. COVID pandemic), and highlight areas for service improvement.

Abstract
IntroductionEndonasal endoscopic surgery has changed the treatment perspectives for different lesions of the hypothalamic–pituitary region. The metastases of the hypothalamic–pituitary region represent 0.4% of all intracranial metastatic tumors and account for only 1.8% of surgically managed pituitary lesions. The aim of tshis study is to describe a single-center institutional experience with 13 cases of hypothalamic–pituitary metastasis focused on presurgical workup, the evolution of the surgical technique, and postsurgical management according to our protocols, showing effects on progression-free and overall survival rates for this relatively uncommon location.Material and MethodsWe retrospectively reviewed the whole series of patients that received the endoscopic endonasal approach at the Division of Neurosurgery at the University of Naples “Federico II” undergoing surgery from January 1997 to December 2021. We identified 13 cases whose pathology reports revealed a metastatic lesion. Statistical analysis was performed to determine the Kaplan–Meier survival function and assess for log-rank differences in survival based on gender, surgical treatment, and postoperative therapy (p-value < 0.02*).ResultsThe pathology report disclosed lung adenocarcinoma (six cases, 46%), breast adenocarcinoma (two cases, 15.4%), clear cell renal carcinoma (one case, 7%), melanoma (one case, 7%), colorectal adenocarcinoma (one case, 7%), uterine cervix carcinoma (one case, 7%), and follicular thyroid carcinoma (one case, 7%). A standard endoscopic endonasal approach was performed in 10 patients (76.9%), while an extended endonasal procedure was performed in only three cases (23%). Biopsy was the surgical choice in five patients with infiltrative and invasive lesions and a poor performance status (38%), while in the cases where neurovascular decompression was necessary, a subtotal resection was achieved in five patients (38%) and partial resection in three patients (23%). Recovery of visual field defect was observed in six of seven patients with visual loss (85.7%), improvement of oculomotor nerve palsy occurred in four of seven patients with this defect (57.1%), while the impairment of oculomotor palsy was observed in three patients (42.9%). Visual function was stable in the other patients. The median progression-free survival and overall survival were 14 and 18 months, respectively. There were statistically significant differences in PFS and OS in patients who underwent adjuvant radiotherapy (p=0.019 is referred to OS and p=0.017 to PFS, respectively; p-value = 0.02).ConclusionsThe endoscopic endonasal approach is a viable approach for the management of hypothalamic–pituitary metastases as this surgery provides an adequate opportunity to obtain tissue sample and neurovascular decompression, both being crucial for continuing the integrated adjuvant therapy protocols.

Automated operative workflow analysis of endoscopic pituitary surgery using machine learning: development and preclinical evaluation (IDEAL stage 0). J Neurosurg 2022; 137:51-58. [PMID: 34740198 PMCID: PMC10243668 DOI: 10.3171/2021.6.jns21923] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Accepted: 06/15/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Surgical workflow analysis involves systematically breaking down operations into key phases and steps. Automatic analysis of this workflow has potential uses for surgical training, preoperative planning, and outcome prediction. Recent advances in machine learning (ML) and computer vision have allowed accurate automated workflow analysis of operative videos. In this Idea, Development, Exploration, Assessment, Long-term study (IDEAL) stage 0 study, the authors sought to use Touch Surgery for the development and validation of an ML-powered analysis of phases and steps in the endoscopic transsphenoidal approach (eTSA) for pituitary adenoma resection, a first for neurosurgery. METHODS The surgical phases and steps of 50 anonymized eTSA operative videos were labeled by expert surgeons. Forty videos were used to train a combined convolutional and recurrent neural network model by Touch Surgery. Ten videos were used for model evaluation (accuracy, F1 score), comparing the phase and step recognition of surgeons to the automatic detection of the ML model. RESULTS The longest phase was the sellar phase (median 28 minutes), followed by the nasal phase (median 22 minutes) and the closure phase (median 14 minutes). The longest steps were step 5 (tumor identification and excision, median 17 minutes); step 3 (posterior septectomy and removal of sphenoid septations, median 14 minutes); and step 4 (anterior sellar wall removal, median 10 minutes). There were substantial variations within the recorded procedures in terms of video appearances, step duration, and step order, with only 50% of videos containing all 7 steps performed sequentially in numerical order. Despite this, the model was able to output accurate recognition of surgical phases (91% accuracy, 90% F1 score) and steps (76% accuracy, 75% F1 score). CONCLUSIONS In this IDEAL stage 0 study, ML techniques have been developed to automatically analyze operative videos of eTSA pituitary surgery. This technology has previously been shown to be acceptable to neurosurgical teams and patients. ML-based surgical workflow analysis has numerous potential uses-such as education (e.g., automatic indexing of contemporary operative videos for teaching), improved operative efficiency (e.g., orchestrating the entire surgical team to a common workflow), and improved patient outcomes (e.g., comparison of surgical techniques or early detection of adverse events). Future directions include the real-time integration of Touch Surgery into the live operative environment as an IDEAL stage 1 (first-in-human) study, and further development of underpinning ML models using larger data sets.

Abstract
Cushing disease is a disorder of hypercortisolemia caused by hypersecretion of adrenocorticotropic hormone by a pituitary adenoma and is a rare diagnosis. Cushing disease presents with characteristic clinical signs and symptoms associated with excess cortisol, but diagnosis is difficult and often relies on repeated and varied endocrinologic assays and neuroradiologic investigations. Gold standard treatment is surgical resection of adrenocorticotropic hormone-secreting pituitary adenoma, which is curative. Patients require close endocrinologic follow-up for maintenance of associated neuroendocrine deficiencies and surveillance for potential recurrence. Medications, radiation therapy, and bilateral adrenalectomy are alternative treatments for residual or recurrent disease.

Telemedicine for Neurosurgery Consultations at a Pituitary Center of Excellence: Patient Preference and Willingness to Proceed with Surgery. J Neurol Surg B Skull Base 2022; 84:1-7. [PMID: 36743713 PMCID: PMC9897892 DOI: 10.1055/a-1715-0077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 11/28/2021] [Indexed: 02/07/2023] Open
Abstract
Objective The purpose of this study was to evaluate pituitary tumor patient satisfaction with telemedicine, patient preference for telemedicine, potential socioeconomic benefit of telemedicine, and patients' willingness to proceed with surgery based on a telemedicine visit alone. Method In total, 134 patients who had pituitary surgery and a telemedicine visit during the coronavirus disease 2019 (COVID-19) pandemic (April 23, 2020-March 4, 2021) were called to participate in a 13-part questionnaire. Chi-square, ANOVA, and Wilcoxon Rank Sum tests were used to determine significance. Result Of 134 patients contacted, 90 responded (67%). Ninety-five percent were "satisfied" or "very satisfied" with their telemedicine visit, with 62% stating their visit was "the same" or "better" than previous in-person appointments. Eighty-two percent of the patients rated their telemedicine visit as "easy" or "very easy." On average, patients saved 150 minutes by using telemedicine compared with patient reported in-person visit times. Seventy-seven percent of patients reported the need to take off from work for in-person visits, compared with just 12% when using telemedicine. Forty-nine percent of patients preferred in-person visits, 34% preferred telemedicine, and 17% had no preference. Fifty percent of patients said they would feel comfortable proceeding with surgery based on a telemedicine visit alone. Patients with both initial evaluation and follow-up conducted via telemedicine were more likely to feel comfortable proceeding with surgery based on a telemedicine visit alone compared with patients who had only follow-up telemedicine visits ( p = 0.051). Conclusion Many patients are satisfied with telemedicine visits and feel comfortable proceeding with surgery based on a telemedicine visit alone. Telemedicine is an important adjunct to increase access to care at a Pituitary Center of Excellence.

Diagnostic Pitfalls in Cushing Disease: Surgical Remission Rates, Test Thresholds, and Lessons Learned in 105 Patients. J Clin Endocrinol Metab 2022; 107:205-218. [PMID: 34478542 PMCID: PMC8684536 DOI: 10.1210/clinem/dgab659] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Indexed: 11/19/2022]
Abstract
CONTEXT Confirming a diagnosis of Cushing disease (CD) remains challenging, yet is critically important before recommending transsphenoidal surgery for adenoma resection. OBJECTIVE To describe predictive performance of preoperative biochemical and imaging data relative to post-operative remission and clinical characteristics in patients with presumed CD. DESIGN, SETTING, PATIENTS, INTERVENTIONS Patients (n = 105; 86% female) who underwent surgery from 2007 through 2020 were classified into 3 groups: group A (n = 84) pathology-proven ACTH adenoma; group B (n = 6) pathology-unproven but with postoperative hypocortisolemia consistent with CD; and group C (n = 15) pathology-unproven, without postoperative hypocortisolemia. Group A + B were combined as confirmed CD and group C as unconfirmed CD. MAIN OUTCOMES Group A + B was compared with group C regarding predictive performance of preoperative 24-hour urinary free cortisol (UFC), late night salivary cortisol (LNSC), 1-mg dexamethasone suppression test (DST), plasma ACTH, and pituitary magnetic resonance imaging (MRI). RESULTS All groups had a similar clinical phenotype. Compared with group C, group A + B had higher mean UFC (P < 0.001), LNSC (P = 0.003), DST (P = 0.06), and ACTH (P = 0.03) and larger MRI-defined lesions (P < 0.001). The highest accuracy thresholds were: UFC 72 µg/24 hours; LNSC 0.122 µg/dL, DST 2.70 µg/dL, and ACTH 39.1 pg/mL. Early (3-month) biochemical remission was achieved in 76/105 (72%) patients: 76/90(84%) and 0/15(0%) of group A + B vs group C, respectively, P < 0.0001. In group A + B, nonremission was strongly associated with adenoma cavernous sinus invasion. CONCLUSIONS Use of strict biochemical thresholds may help avoid offering transsphenoidal surgery to presumed CD patients with equivocal data and improve surgical remission rates. Patients with Cushingoid phenotype but equivocal biochemical data warrant additional rigorous testing.

Abstract
Acromegaly is a disease that occurs secondary to high levels of GH, most often from a hormone-secreting pituitary adenoma, with multisystem adverse effects. Diagnosis includes serum GH and IGF-1 levels, and obtaining an MRI pituitary protocol to assess for a functional pituitary adenoma. Attempted gross total resection of the GH-secreting adenoma is the gold standard in treatment for patients with acromegaly for a goal of biochemical remission. Medical and radiation therapies are available when patients do not achieve biochemical cure after surgical therapy.

Abstract
OBJECTIVE Pituitary adenoma surgery has evolved rapidly in recent decades. This study aims to determine current practice across a wide range of European neurosurgical centers. METHODS A list of eligible departments performing pituitary adenoma surgery was created. The survey consisted of 58 questions. For analysis, the departments were divided into four subgroups: academic/nonacademic, high-volume/low-volume, "mainly endoscopic/mainly microscopic practice," and geographical regions. RESULTS Data from 254 departments from 34 countries were obtained. In 108 centers (42.5%), <30 pituitary adenomas were operated per year. Twenty (7.9%) centers performed >100 adenoma surgeries per year. Number of neurosurgeons performing endonasal surgeries are as follows: 1 in 24.9% of centers and 2 in 49.8% of centers. All residents assisted endonasal surgeries in 126 centers (49.8%). In 28 centers (21.1%), all residents performed endonasal surgery under supervision during residency. In 141 centers (56.8%), the endoscopic approach was used in >90% of the surgeries. Regular pituitary board (either weekly or once a month) meetings were held in 147 centers (56.3%). Nonfunctioning adenomas represent >70% of pituitary caseload in 149 centers (58.7%). CONCLUSIONS In our survey, most centers perform less than 100 surgeries for pituitary adenomas. In most centers, pituitary surgeries are performed by one or two neurosurgeons. Residents have a limited exposure to this type of surgery, and the formal pituitary board is not a standard. Nonfunctioning adenomas make up most of surgically treated adenomas. This study can serve as a benchmark for further analyses of pituitary adenoma centers in Europe.

Abstract
Introduction Cushing's disease is a state of chronic and excessive cortisol levels caused by a pituitary adenoma Research question CD is a complex entity and often entails difficulties in its diagnosis and management. For that reason, there are still controversial points to that respect. The aim of this consensus paper of the skull base section of the EANS is to review the main aspects of the disease a neurosurgeon has to know and also to offer updated recommendations on the controversial aspects of its management. Material and methods PUBMED database was used to search the most pertinent articles published on the last 5 years related with the management of CD. A summary of literature evidence was proposed for discussion within the EANS skull base section and other international experts. Results This article represents the consensual opinion of the task force regarding optimal management and surgical strategy in CD Discussion and conclusion After discussion in the group several recommendations and suggestions were elaborated. Patients should be treated by an experienced multidisciplinary team. Accurate clinical, biochemical and radiological diagnosis is mandatory. The goal of treatment is the complete adenoma resection to achieve permanent remission. If this is not possible, the treatment aims to achieving eucortisolism. Radiation therapy is recommended to patients with CD when surgical options have been exhausted. All patients in remission should be tested all life-long. Modalities of management of Cushing disease and recommendations based on the literature and expert's opinion.

Abstract
PURPOSE To evaluate the impact of using consistent complication-avoidance protocols in patients undergoing endoscopic pituitary adenoma surgery including techniques for avoiding anosmia, epistaxis, carotid artery injury, hypopituitarism, cerebrospinal fluid leaks and meningitis. METHODS All patients undergoing endoscopic adenoma resection from 2010 to 2020 were included. Primary outcomes included 90-day complication rates, gland function outcomes, reoperations, readmissions and length of stay. Secondary outcomes were extent of resection, short-term endocrine remission, vision recovery. RESULTS Of 514 patients, (mean age 51 ± 16 years; 78% macroadenomas, 19% prior surgery) major complications occurred in 18(3.5%) patients, most commonly CSF leak (9, 1.7%) and meningitis (4, 0.8%). In 14 of 18 patients, complications were deemed preventable. Four (0.8%) had complications with permanent sequelae (3 before 2016): one unexplained mortality, one stroke, one oculomotor nerve palsy, one oculoparesis. There were no internal carotid artery injuries, permanent visual worsening or permanent anosmia. New hypopituitarism occurred in 23/485(4.7%). Partial or complete hypopituitarism resolution occurred in 102/193(52.8%) patients. Median LOS was 2 days; 98.3% of patients were discharged home. Comparing 18 patients with major complications versus 496 without, median LOS was 7 versus 2 days, respectively p < 0.001. Readmissions occurred in 6%(31/535), mostly for hyponatremia (18/31). Gross total resection was achieved in 214/312(69%) endocrine-inactive adenomas; biochemical remission was achieved in 148/209(71%) endocrine-active adenomas. Visual field or acuity defects improved in 126/138(91.3%) patients. CONCLUSION This study suggests that conformance to established protocols for endoscopic pituitary surgery may minimize complications, re-admissions and LOS while enhancing the likelihood of preserving gland function, although there remains opportunity for further improvements.

Abstract
PURPOSE Surgical workflow analysis seeks to systematically break down operations into hierarchal components. It facilitates education, training, and understanding of surgical variations. There are known educational demands and variations in surgical practice in endoscopic transsphenoidal approaches to pituitary adenomas. Through an iterative consensus process, we generated a surgical workflow reflective of contemporary surgical practice. METHODS A mixed-methods consensus process composed of a literature review and iterative Delphi surveys was carried out within the Pituitary Society. Each round of the survey was repeated until data saturation and > 90% consensus was reached. RESULTS There was a 100% response rate and no attrition across both Delphi rounds. Eighteen international expert panel members participated. An extensive workflow of 4 phases (nasal, sphenoid, sellar and closure) and 40 steps, with associated technical errors and adverse events, were agreed upon by 100% of panel members across rounds. Both core and case-specific or surgeon-specific variations in operative steps were captured. CONCLUSIONS Through an international expert panel consensus, a workflow for the performance of endoscopic transsphenoidal pituitary adenoma resection has been generated. This workflow captures a wide range of contemporary operative practice. The agreed "core" steps will serve as a foundation for education, training, assessment and technological development (e.g. models and simulators). The "optional" steps highlight areas of heterogeneity of practice that will benefit from further research (e.g. methods of skull base repair). Further adjustments could be made to increase applicability around the world.

Abstract
OBJECTIVE Perioperative management of patients with sellar lesions is complex, requiring input from a multidisciplinary team of specialists for ongoing management of both endocrinological and neurosurgical issues. Here, the authors reviewed the experience of a single multidisciplinary center over 10 years to identify key postoperative practices that ensure positive outcomes for patients with sellar lesions who undergo transsphenoidal surgery. METHODS The authors performed a retrospective review of all transsphenoidal operations carried out by the senior author at a single center from April 2008 through November 2018. They included only adult patients and recorded perioperative management. They also reviewed the evolution of clinical practices for perioperative care at their institution to identify strategies for ensuring positive patient outcomes, and they reviewed the literature on select related topics. RESULTS In total, 1023 operations in 928 patients were reviewed. Of these, 712 operations were for pituitary adenomas (69.6%), and 122 were for Rathke cleft cysts (11.9%). The remainder included operations for craniopharyngiomas (3.6%), arachnoid cysts (1.7%), pituitary tumor apoplexy (1.0%), and other sellar pathologies (12.2%). Among the reviewed operations, the median hospital stay was 3 days (IQR 2-3). Patient management details during the pre-, intra-, and postoperative periods were identified, including both shared characteristics of all patients undergoing transsphenoidal surgery and unique characteristics that are specific to certain lesion types or patient populations. CONCLUSIONS Patients with sellar lesions who undergo transsphenoidal surgery require complex, multidisciplinary perioperative care to monitor for common adverse events and to improve outcomes, but there is a dearth of high-quality evidence guiding most perioperative practices. Here, the authors reviewed practices at their institution across more than 1000 transsphenoidal operations that may help ensure successful patient outcomes.

Abstract
Background Outcome disparities have been documented at safety-net hospitals (SNHs), which disproportionately serve vulnerable patient populations. Using a nationwide retrospective cohort, we assessed inpatient outcomes following brain tumor craniotomy at SNHs in the United States. Methods We identified all craniotomy procedures in the National Inpatient Sample from 2002–2011 for brain tumors: glioma, metastasis, meningioma, and vestibular schwannoma. Safety-net burden was calculated as the number of Medicaid plus uninsured admissions divided by total admissions. Hospitals in the top quartile of burden were defined as SNHs. The association between SNH status and in-hospital mortality, discharge disposition, complications, hospital-acquired conditions (HACs), length of stay (LOS), and costs were assessed. Multivariate regression adjusted for patient, hospital, and severity characteristics. Results 304,719 admissions were analyzed. The most common subtype was glioma (43.8%). Of 1,206 unique hospitals, 242 were SNHs. SNH admissions were more likely to be non-white (P < .001), low income (P < .001), and have higher severity scores (P = .034). Mortality rates were higher at SNHs for metastasis admissions (odds ratio [OR] = 1.48, P = .025), and SNHs had higher complication rates for meningioma (OR = 1.34, P = .003) and all tumor types combined (OR = 1.17, P = .034). However, there were no differences at SNHs for discharge disposition or HACs. LOS and hospital costs were elevated at SNHs for all subtypes, culminating in a 10% and 9% increase in LOS and costs for the overall population, respectively (all P < .001). Conclusions SNHs demonstrated poorer inpatient outcomes for brain tumor craniotomy. Further analyses of the differences observed and potential interventions to ameliorate interhospital disparities are warranted.

Abstract
Surgical experience is of paramount importance to reach therapeutic success and minimize operative complications. In the field of pituitary surgery, this led to the concept of Pituitary Center of Excellence (PTCOE) defined as a center where an interdisciplinary team works in collaboration and where surgeons can be trained appropriately to reach and keep excellence in daily practice. To review the literature to define the optimal referral population size to establish a PTCOE to optimize both training and specific field research. A review of the literature was performed about epidemiology. The time needed to observe 200 cases of PAs in a single PTCOE and to reach the minimal surgical experience threshold (MSET) was calculated for different referral population groups. The time needed to reach MSET decreased as population size increased. We defined a population as the optimal one to be served by a single PTCOE with a single dedicated neurosurgeon. PTCOEs should be established after an analysis of the referral population, number of cases suitable for surgical treatment and number of dedicated neurosurgeons.

Abstract
OBJECTIVE Acromegaly is a rare condition and there is often a long path to diagnosis for many patients. We sought to explore patient's perceptions and understanding of acromegaly, to examine the quality of communication and find gaps in the information provided at diagnosis. DESIGN A prospective study using qualitative research methodology and grounded theory. A semi-structured interview was conducted with 18 patients treated for acromegaly in a single tertiary centre and verbatim transcripts were thematically analysed for overarching themes. RESULTS Eighteen patients with acromegaly were interviewed. The mean age of participants was 52 (range 30-72). Four overarching themes emerged; (1) Patients rely on online resources to understand acromegaly in the time between diagnosis and tertiary care clinic; (2) There is not enough support available for patients; (3) Patients have a basic understanding of acromegaly and associated conditions, but the long-term impact is underestimated; and (4) Patients initially felt intimidated by the multidisciplinary team panel, but overall found it useful. CONCLUSION Acromegalic patients have a strong need for information at the point of initial diagnosis, in particular online resources and interaction with other experienced patients. Wider dissemination of patient educational resources into primary and secondary care settings may improve overall patient satisfaction, treatment adherence and subsequent health care provider-patient relationships.

Abstract
AIM To clarify the concept of 'aggressive pituitary adenoma' using analysis of the current concepts, as well as to determine the optimal treatment algorithm for this disease and the place of chemotherapy in this treatment. Pituitary adenomas comprise from 10 to 15% of intracranial neoplasms. Despite the fact that pituitary adenomas are benign neoplasms, in 25-55% of cases they demonstrate invasive growth, growing into the surrounding structures (sphenoid sinus, cavernous sinus, etc.). Due to the lack of a standard definition of aggressive pituitary adenomas (due to the lack of clear criteria for this disease), there are no studies in the literature reporting optimal treatment for this group of patients, except for several publications describing the use of Temozolomide as palliative therapy.

Abstract
Endoscopic transsphenoidal surgery for pituitary adenoma is a safe and highly effective first-line treatment that is well tolerated by patients. Potential complications are plenty, and there is a large variation in complexity of surgery. This article presents the philosophy, surgical techniques, and outcomes of a high-volume pituitary adenoma center. Three surgical videos illustrate some procedures. The experience has reinforced the authors' belief that experience and surgical volume are key to high quality of care.

Abstract
BACKGROUND Geographic variations in health care costs have been reported for many surgical specialties. OBJECTIVE In this study, we sought to describe national and regional costs associated with transsphenoidal pituitary surgery (TPS). METHODS Data from the Truven-MarketScan 2010-2014 were analyzed. We examined overall total, hospital/facility, physician, and out-of-pocket payments in patients undergoing TPS including technique-specific costs. Mean payments were obtained after risk adjustment for patient-level and system-level confounders and estimated differences across regions. RESULTS The estimated overall annual burden was $43 million/year in our cohort. The average overall total payment associated with TPS was $35,602.30, hospital/facility payment was $26,980.45, physician payment was $4685.95, and out-of-pocket payment was $2330.78. Overall total and hospital/facility costs were highest in the West and lowest in the South (both P < 0.001), whereas physician reimbursements were highest in the North-east and lowest in the South (P < 0.001). There were no differences in out-of-pocket expenses across regions. On a national level, there were significantly higher overall total and hospital/facility payments associated with endoscopic compared with microscopic procedures (both P < 0.001); there were no significant differences in physician payments or out-of-pocket expenses between techniques. There were also significant within-region cost differences in overall total, hospital/facility, and physician payments in both techniques as well as in out-of-pocket expenses associated with microsurgery. There were no significant regional differences in out-of-pocket expenses associated with endoscopic surgery. CONCLUSIONS Our results show significant geographic cost disparities associated with TPS. Understanding factors behind disparate costs is important for developing cost containment strategies.

Abstract
BACKGROUND The management of pituitary apoplexy, caused by acute hemorrhage and/or infarction of a pituitary adenoma, is debated. OBJECTIVE To analyze clinical characteristics of patients undergoing endoscopic endonasal approaches (EEAs) for pituitary apoplexy. METHODS A retrospective review of patients at our institution from 2012 to 2018 undergoing EEA for pituitary apoplexy diagnosed clinically and with imaging/pathologic findings. Analysis included demographics, symptoms, neuroendocrine deficits, neuroimaging, complications, symptom resolution, and follow-up details. RESULTS Fifty patients (mean age, 53 years) were included. Preoperative symptoms included headache (86%), vision loss (62%), and cranial nerve paresis (40%). Mean tumor diameter was 2.7 cm and extrasellar extension was observed in 96% of tumors. Twenty-eight tumors were hemorrhagic (76%), 24 were necrotic (65%), and 13 (35%) had both features. Magnetic resonance imaging showed gross total resection in 58% of patients. Headache and vision loss improved in 87% and 86% of presenting patients. Cranial nerve paresis resolved in 72% of patients, partially improved in 11%, and remained unchanged in 17%. There were no deaths or carotid artery injuries. Surgical complications included postoperative cerebrospinal fluid leak (n = 4, 8%), epistaxis (n = 2, 4%), postoperative abscess (n = 1, 2%), and transient postoperative vision loss requiring reoperation (n = 1, 4%). Endocrinopathies improved in 21% of patients and panhypopituitarism persisted in 48% and developed in 6% of patients. Mean follow-up time was 26 months; 2 patients experienced recurrence. CONCLUSIONS EEA for pituitary apoplexy is effective in rapidly improving headache and visual symptoms. Although neuro-ophthalmic deficits often improve over time, panhypopituitarism persists in most patients after surgical resection.

Abstract
Pituitary tumors are a heterogeneous group of lesions (usually benign) and proper understanding of the anatomy, physiology, and pathology of the hypothalamic/pituitary region is essential to make an accurate diagnosis and define the essential treatment options (i.e., surgery, medical therapies, and radiotherapy, alone or in combination). Surgery is the primary treatment for acromegaly, Cushing disease, thyroid-stimulating hormone-secreting adenomas, resistant prolactinomas, and nonfunctioning pituitary adenomas causing mass effect. Medical and radiation therapy are reserved in cases in which surgery is not possible or does not provide a complete cure. In the last decades, tremendous innovations (i.e., targeted drugs and refined surgical tools and techniques) have expanded the treatment strategies for pituitary adenomas. We herein report the current indications for and depiction of the surgical techniques in pituitary surgery, review current medical treatments, and provide a glimpse of future possibilities.

Abstract
Pituitary apoplexy is a clinical condition with acute-onset headaches, vision loss, and/or pituitary dysfunction associated with a hemorrhagic or infarcted pituitary tumor or cyst. Treatment varies based on clinical presentation, although often urgent or emergent surgical resection is indicated. Conservative treatment strategies tend to be applied for more mild conditions of apoplexy. Overall outcomes may be similar in this less severe cohort. Acute-onset vision loss with apoplexy should be treated with urgent or emergent surgical evacuation of hematoma and resection of tumor when possible.

Interfacility neurosurgical transfers: an analysis of nontraumatic inpatient and emergency department transfers with implications for improvements in care. J Neurosurg 2019; 131:281-289.

Abstract
OBJECTIVE Interfacility neurosurgical transfers to tertiary care centers are driven by a number of variables, including lack of on-site coverage, limited available technology, insurance factors, and patient preference. The authors sought to assess the timing and necessity of surgery and compared transfers to their institution from emergency departments (ED) and inpatient units at other hospitals. METHODS Adult neurosurgical patients who were transferred to a single tertiary care center were analyzed over 12 months. Patients with traumatic injuries or those referred from skilled nursing facilities or rehabilitation centers were excluded. RESULTS A total of 504 transferred patients were included, with mean age 55 years (range 19-92 years); 53% of patients were women. Points of origin were ED in 54% cases and inpatient hospital unit in 46%, with a mean distance traveled for most patients of 119 miles. Broad diagnosis categories included brain tumors (n = 142, 28%), vascular lesions, including spontaneous and hypertensive intracerebral hemorrhage (n = 143, 28%), spinal lesions (n = 126, 25%), hydrocephalus (n = 45, 9%), wound complications (n = 29, 6%), and others (n = 19, 4%). Patients transferred from inpatient units had higher rates of surgical intervention (75% vs 57%, p < 0.001), whereas patients transferred from the ED had higher rates of urgent surgery (20% vs 8%, p < 0.001) and shorter mean time to surgery (3 vs 5 days, p < 0.001). Misdiagnosis rates were higher among ED referrals (11% vs 4%, p = 0.008). Across the same timeframe, patients undergoing elective admission (n = 1986) or admission from the authors' own ED (n = 248) had significantly shorter lengths of stay (p < 0.001) and ICU days (p < 0.001) than transferred patients, as well as a significantly lower total cost ($44,412, $46,163, and $72,175, respectively; p < 0.001). CONCLUSIONS The authors present their 12-month experience from a single tertiary care center without Level I trauma designation. In this cohort, 65% of patients required surgery, but the rates were higher among inpatient referrals, and misdiagnosis rates were higher among ED transfers. These data suggest that admitting nonemergency patients to local hospitals may improve diagnostic accuracy of patients requiring urgent care, more precisely identify patients in need of transfer, and reduce costs. Referring facilities may lack necessary resources or expertise, and the Emergency Medical Treatment and Active Labor Act (EMTALA) obligates tertiary care centers to accept these patients under those circumstances. Telemedicine and integration of electronic medical records may help guide referring hospitals to pursue additional workup, which may eliminate the need for unnecessary transfer and provide additional cost savings.

Abstract
PURPOSE Acromegaly may be associated with an increased risk of complex intraoperative management and anesthetic complications. No study addressed whether pretreatment with somatostatin receptor ligands (SRLs) affects anesthesiologic management. METHODS We studied 211 consecutive acromegalic patients who had a recorded intraoperative computerized anesthetic record (ICAR) available for analysis. Ninety-six (45.5%) patients were SRL-pretreated while 115 patients were treatment naïve. RESULTS Treatment with SRLs reduced mean basal growth hormone level from 23.8 ± 4.2 to 5.9 ± 1.3 µg/L. Normalization of insulin-like growth factor-1 was achieved in 26 patients (27.1%). The frequency of comorbidities at surgery was similar in the two groups. Five patients with difficult intubation were naïve (4.3%) as compared with 5 SRL-pretreated patients (5.2%; P = 1.0). ICAR registration did not show any significant change of intraoperative vital parameters in the two groups of patients as well as in the intraoperative utilization of drugs. Total duration of anesthesia and surgery were similar in the two groups. Four patients with an intraoperative adverse event were naïve (3.5%) as compared with 4 SRL-pretreated patients (4.2%; P = 1.00). Remission of disease occurred in 83 of 114 naïve patients (72.8%) and in 57 of 93 SRL-pretreated patients (61.3%; P = 0.11). CONCLUSIONS SRL-pretreatment of patients with acromegaly had no significant impact on intraoperative anesthesiologic management. Despite a better Cormack-Lehane score in SRL-pretreated than in naïve patients, the rate of difficult intubation was similar in both groups. SRL-pretreatment did not affect the rate of surgical remission or complications as well.

Abstract
OBJECTIVE A five-level training program was first proposed 10 years ago for surgeons learning endoscopic endonasal surgery (EES) of the skull base. Levels were based on the complexity of anatomy, risk of neurovascular injury, intradural dissection, technical difficulty and vascularity of tumors. METHOD A three-phase validation concept is proposed: 1) face validity (the classification is related to clinically significant elements), 2) construct validity (the classification predicts the outcome), and 3) inter-team validation (the classification applies to other surgical teams). Consecutive cases over a 1-year time span were retrospectively classified. Primary outcome measures included: complication rates (cranial nerve injury, stroke and vascular injury, cerebrospinal fluid [CSF] leak and infection), estimated blood loss and duration of surgery. RESULTS Two hundred and nine consecutive cases were analyzed. The distribution of cases for each category was: 63 cases in level II, 70 cases in level III, 66 cases in level IV, and 10 cases in level V. Construct validity demonstrated statistical difference with increasing rate of complications from level II to level III and from level III to level IV; also, specific rates of cranial nerve injury and CSF leak increased between levels III and IV. Face validity identified 162 citations since publication of the original article. Inter-team validation demonstrated no difference between two teams of surgeons. CONCLUSION This study provides a three-phase validation of training levels for endoscopic skull base surgery. Adoption of a progressive systematic approach to learning EES from least complex to advanced procedures is expected to minimize the risks while surgical teams gain experience. LEVEL OF EVIDENCE 3 Laryngoscope, 129:2253-2257, 2019.

Abstract
The Korean Endocrine Society (KES) published clinical practice guidelines for the treatment of acromegaly in 2011. Since then, the number of acromegaly cases, publications on studies addressing medical treatment of acromegaly, and demands for improvements in insurance coverage have been dramatically increasing. In 2017, the KES Committee of Health Insurance decided to publish a position statement regarding the use of somatostatin analogues in acromegaly. Accordingly, consensus opinions for the position statement were collected after intensive review of the relevant literature and discussions among experts affiliated with the KES, and the Korean Neuroendocrine Study Group. This position statement includes the characteristics, indications, dose, interval (including extended dose interval in case of lanreotide autogel), switching and preoperative use of somatostatin analogues in medical treatment of acromegaly. The recommended approach is based on the expert opinions in case of insufficient clinical evidence, and where discrepancies among the expert opinions were found, the experts voted to determine the recommended approach.

Abstract
BACKGROUND Assessment of presurgical hypothalamic involvement (psHI) and treatment-related hypothalamic damage (trHD) is relevant for the decision on risk-adapted treatment and rehabilitation strategies in craniopharyngioma. PATIENTS AND METHODS 129 surgical reports of childhood-onset craniopharyngioma patients recruited 2007-2014 in KRANIOPHARYNGEOM 2007 were analyzed. Data on psHI were available based on surgeon's (63%), reference neuroradiologist's (95%), and local radiologist's (23%) assessment. The surgical degree of resection (DoR) was assessed by neurosurgeon (95%), reference neuroradiologist (73%), and local radiologist (61%). TrHD was assessed by neurosurgeon (33%), by reference neuroradiologist (95%), and by local radiologist (2%). Neurosurgical center size was categorized based on patient load. RESULTS Surgical assessments on psHI (n = 78), DoR (n = 89) and trHD (n = 42) as documented in surgical reports could be compared with the assessment of respective parameters by reference neuroradiologist. Differences with regard to DoR (p = 0.0001) and trHD (p < 0.0001) were detectable between surgeon's and reference neuroradiologist's assessment, whereas psHI was assessed similarly. Concordance for DoR and trHD was observed in 48 and 62%, respectively. Surgeons estimated a higher rate of complete resections and a lower rate of trHD. Neuroradiological reference assessment of trHD had higher predictive value for hypothalamic sequelae then surgical assessment. Observed differences were not related to neurosurgical center size. CONCLUSIONS Observed differences between surgical and neuroradiological estimation of risk factors in craniopharyngioma support the necessity of neuroradiological reference review to assure standards of quality. This could be established by central internet-based neuroradiological review in KRANIOPHARYNGEOM 2007. Standardization of surgical reports including specific assessment of tumor/damage location is recommended.

Abstract
BACKGROUND Prolonged length of stay (pLOS), disease-related complications, and 30-day readmissions are important quality metrics under the Affordable Care Act. The purpose of our study was to investigate the effect of patient-level and hospital-level factors on these outcomes for patients admitted for transsphenoidal pituitary surgery. METHODS The Statewide Planning and Research Cooperative System (SPARCS) database was queried to investigate 30-day readmissions and pLOS for transsphenoidal pituitary surgery in New York from 1995 to 2015. Multivariate logistic regression, adjusting for patient and hospital characteristics, was performed to assess the effect of these variables on the outcomes of interest. RESULTS A total of 9950 patients underwent transsphenoidal pituitary surgery; 7122 (72%), 2394 (24%), and 434 (4%) patients were treated at high-volume, medium-volume, and low-volume centers, respectively. Patient factors associated with treatment at high-volume centers (HVCs) included: top income quartile, private insurance, urban residence, and white or Asian race (p < 0.05). Patient variables associated with treatment at low-volume centers (LVCs) included: age >65 years, elevated Charlson comorbidity index (CCI) scores, bottom income quartile, Medicaid and Medicare insurance, rural residence, black race, and Hispanic ethnicity (p < 0.05). Variables predictive of prolonged hospitalizations in our multivariable model included black race, Hispanic ethnicity, Medicaid insurance, low income, female gender, LVC, and comorbidities (panhypopituitarism, hypothyroidism, diabetes insipidus [DI], visual disturbances, CCI) while predictors of readmissions included Asian race, female gender, and comorbidities (Cushing syndrome, DI, CCI). CONCLUSION Patients undergoing transsphenoidal pituitary surgery at HVCs have shorter hospitalizations, fewer postoperative electrolyte abnormalities, and lower charges; however, socioeconomic factors may influence access to quality care.

Abstract
Background: Pituitary disorders spectrum includes a wide variety of diseases.This study aimed at a comprehensive description of such disorders for patients from Faiha Specialized Diabetes, Endocrine and Metabolism Center (FDEMC) in Basrah (Southern Iraq). Methods: Retrospective data analysis of FDEMC for the period from January 2012 through June 2017. We included all patients with pituitary disorders who have MRI pituitary. Results: The pituitary disorders were more common among women. Those with macroadenoma were older than those with microadenoma with nearly equal gender prevalence of macroadenoma. Pituitary adenoma constituted the bulk of pituitary disorders in this registry (67.2%). Growth hormone secreting adenoma were the commonest adenoma seen in 41.0% followed by clinically non-functioning pituitary adenoma(NFPA)in 31.4% and prolactinoma in 26.9%. About 64.8% of pituitary adenoma was macroadenoma. Macroadenoma was seen in 73.4 % of growth hormone secreting adenoma, 61.2% in NFPA and 62.0% of prolactinoma (of them six were giant prolactinoma) Conclusion: Pituitary adenoma constituted the bulk of pituitary disorders in Basrah, growth hormone secreting adenoma is the commonest adenoma followed by NFPA and prolactinoma due to referral bias. A change in practice of pituitary adenoma treatment is needed.

Background: Sellar and parasellar region lesions spectrum includes a wide variety of diseases. This study aimed at providing a comprehensive overview of such lesions in patients from Faiha Specialized Diabetes, Endocrine and Metabolism Center (FDEMC) in Basrah (Southern Iraq). Methods: Retrospective data analysis from FDEMC for the period January 2012 through June 2017. We included all patients with sellar and parasellar region lesions who received a MRI scan on their pituitary region Results: The total enrolled patients were 232 (84 men and 148 women),with age range 15-75 years.Pituitary disease and adenoma were more common among women. Those with macroadenoma were older than those with microadenoma, with nearly equal gender prevalence of macroadenoma. Pituitary adenoma constituted the bulk of pituitary disease in this setting (67.2%). Growth hormone secreting adenoma were the most common adenoma seen in 41.0%, followed by clinically non-functioning pituitary adenoma (NFPA) in 31.4% and prolactinoma in 26.9%. About 64.8% of pituitary adenoma was macroadenoma. Macroadenoma was seen in 73.4% of growth hormone secreting adenoma (acromegaly), 61.2% in NFPA and 62.0% of prolactinom a(of them six were giant prolactinoma). Conclusion: Pituitary adenoma constituted the bulk of sellar and parasellar region lesions, growth hormone secreting adenoma is the the most common adenoma followed by NFPA and prolactinoma due to referral bias.

Abstract
Non-functional pituitary adenomas (NFPAs) are benign tumors of the pituitary gland that do not over-secrete hormonal products, therefore, they are generally detected through symptoms of mass effect, including headache, vision loss, or hypopituitarism. There are multiple pathological subtypes of NFPAs, such as null cell adenomas, silent gonadotrophs, silent somatotrophs, silent corticotrophs, and silent subtype 3, all of which can be classified based on immunohistochemical studies and electron microscopy. Despite these numerous pathological subtypes, surgical resection remains the first-line treatment for NFPAs. Diagnosis is best made using high resolution MRI brain with and without gadolinium contrast, which is also helpful in determining the extent of invasion of the tumor and recognizing necessary sinonasal anatomy prior to surgery. Additional pre-operative work-up should include full laboratory endocrine evaluation with replacement of hormone deficiencies, and ideally, full neuro-ophthalmologic exam. Although transcranial surgical approaches to the pituitary gland can be performed, the most common approach used is the transnasal transsphenoidal approach with endoscopic or microscopic visualization. This approach avoids retraction of the brain and cranial nerves during tumor removal. Surgery for symptoms caused by mass effect, including headaches and visual loss, are successfully treated with surgical resection, resulting in improvement in pre-operative symptoms as high as 90% in some reports. Although the risk of complications is low, major and minor events, such as permanent hypopituitarism, persistent CSF leak, and carotid artery injury can occur at rates ranging from zero to about 9%.

Abstract
BACKGROUND Interhospital transfer of neurosurgical patients is common; however, little is known about the impact of transfer parameters on clinical outcomes. Lower survival rates have been reported for patients admitted at night and on weekends in other specialties. Whether time or day of admission affects neurosurgical patient outcomes, specifically those transferred from other facilities, is unknown. OBJECTIVE To examine the impact of the timing of interhospital transfer on the hospital course and clinical outcomes of neurosurgical patients. METHODS All consecutive admissions of patients transferred to our adult neurosurgical service were retrospectively analyzed for a 1-year study period using data from a central transfer database and the electronic health record. RESULTS Patients arrived more often at night (70.8%) despite an even distribution of transfer requests. The lack of transfer imaging did not affect length of stay, intervention times, or patient outcomes. Daytime arrivals had shorter total transfer time, but longer intenstive care unit and overall length of stay (8.7 and 11.6 days, respectively), worse modified Rankin Scale scores, lower rates of functional independence, and almost twice the mortality rate. Weekend admissions had significantly worse modified Rankin Scale scores and lower rates of functional independence. CONCLUSIONS The timing of transfer arrivals, both by hour or day of the week, is correlated with the time to intervention, hospital course, and overall patient outcomes. Patients admitted during the weekend suffered worse functional outcomes and a trend towards increased mortality. While transfer logistics clearly impact patient outcomes, further work is needed to understand these complex relationships.

Abstract
INTRODUCTION Prolactinomas are unique tumors that may go into both hormonal and radiographic remission with dopamine agonist therapy or transsphenoidal surgery. Regardless of modality, the goals of therapy remain the same: (1) biochemical remission, including reduction of prolactin and normalization of sex hormones; (2) radiographic tumor control, with a range including prevention of tumor growth, tumor regression, or complete tumor resolution; (3) resolution of preoperative symptoms, including those that are hormonal or neurologic; and (4) prevention of new hypopituitarism or new neurologic symptoms. AREAS COVERED In the following review, we performed a search of the literature using keywords 'prolactinoma,' 'dopamine agonist,' 'surgery,' 'cost-effectiveness,' 'recurrence,' and 'complication' to compare the relative merits of medical versus surgical therapy for prolactinoma, including special circumstances such as cystic tumors, pregnant patients, and the cost-effectiveness of different strategies. EXPERT COMMENTARY Medical therapy can offer a cure, but surgery provides an important adjunct to patients with resistance or intolerance to dopamine agonists, and offers excellent outcomes including when combined with continued postoperative medical therapy. Further head to head comparisons will benefit patients and practitioners weighing the relative risks and benefits of medical and surgical intervention, including the issue of their relative cost-effectiveness.

Abstract
BACKGROUND Nonfunctioning pituitary adenomas (NFPAs) are the most frequent pituitary tumors. Visual symptoms from NFPAs are common and include visual field defects, loss of central vision, and motility problems resulting in diplopia. OBJECTIVE To create evidence-based guidelines in an attempt to formulate guidance for preoperative ophthalmologic evaluation of NFPA patients. METHODS An extensive literature search was performed. Only clinical articles describing preoperative ophthalmologic evaluation of adult patients with NFPA were included. To ascertain the class of evidence for the posttreatment follow-up, the authors used the Clinical Assessment evidence-based classification. RESULTS Six studies met the inclusion criteria with respect to the questions regarding the preoperative ophthalmologic evaluation of NFPA patients. Based on the studies located through the search, the authors formulated evidence-based recommendations as they pertain to the necessity of ophthalmologic evaluation before surgical treatment. CONCLUSION Preoperative ophthalmologic evaluation is recommended. Such evaluation can provide prognostic factors for recovery and, when paired with postoperative evaluation, documents postoperative change. In addition to formal ophthalmologic examination, tests of value include automated static perimetry and optical coherence tomography. Older patients and patients with longer duration (>4 months) of vision loss should be counseled regarding the reduced chance of postoperative vision improvement.

Abstract
INTRODUCTION With the goal of generate uniform criteria among centers dealing with pituitary tumors and to enhance patient care, the Pituitary Society decided to generate criteria for developing Pituitary Tumors Centers of Excellence (PTCOE). METHODS To develop that task, a group of ten experts served as a Task Force and through two years of iterative work an initial draft was elaborated. This draft was discussed, modified and finally approved by the Board of Directors of the Pituitary Society. Such document was presented and debated at a specific session of the Congress of the Pituitary Society, Orlando 2017, and suggestions were incorporated. Finally the document was distributed to a large group of global experts that introduced further modifications with final endorsement. RESULTS After five years of iterative work a document with the ideal criteria for a PTCOE is presented. CONCLUSIONS Acknowledging that very few centers in the world, if any, likely fulfill the requirements here presented, the document may be a tool to guide improvements of care delivery to patients with pituitary disorders. All these criteria must be accommodated to the regulations and organization of Health of a given country.

Abstract
OBJECTIVE Pituitary apoplexy is a clinical syndrome consisting of neurological and endocrine abnormalities secondary to hemorrhage or ischemia of an underlying pituitary adenoma. The authors investigated whether there was a significant difference in neurological, endocrine, and nonneuroendocrine outcomes for patients with pituitary apoplexy, based on the time between symptom onset and surgical intervention. METHODS The authors retrospectively analyzed the medical records of 32 patients who had presented to their institution with acute pituitary apoplexy and subsequently undergone endonasal transsphenoidal resection in the period from 2003 to 2014. All patients had undergone preoperative MRI demonstrating evidence of apoplexy in the form of intratumoral hemorrhage, ischemia, and necrosis. Neurological deficits, partial or complete endocrinopathy, and nonneuroendocrine abnormalities were analyzed both pre- and postoperatively. RESULTS Preoperatively, neurological deficits including visual loss and cranial nerve palsies were found in 31 (97%) of the 32 patients, endocrinopathy in the form of partial or panhypopituitarism was seen in 28 patients (88%), and nonneuroendocrine signs and symptoms were seen in 32 patients (100%). Thirteen patients (41%) underwent surgery within 72 hours of symptom onset ("early"), whereas 19 patients (59%) underwent surgery more than 72 hours from symptom onset ("delayed"). Early versus delayed resection did not appear to significantly improve visual deficits, total visual loss, resolution of oculomotor palsy, recovery from hypopituitarism, or nonneuroendocrine signs and symptoms such as headache and encephalopathy. Overall, visual improvement was seen in 77% of patients, complete restoration of normal vision in 38% of patients, and resolution of preoperative oculomotor palsies in 81% of patients. Only 6 (21%) of 28 patients showed evidence of partial hormone recovery following preoperative hypopituitarism. An absence of benefit for early surgery held true even when considering time to surgery from symptom onset as a continuous variable. CONCLUSIONS Neurological deficits such as visual loss and cranial neuropathies show moderate improvement following surgical decompression, as does preoperative hypopituitarism. The timing of surgical intervention relative to the onset of symptoms does not appear to significantly affect the resolution of neurological or endocrinological deficits.
