Abstract Objective: Analyzing the rate of structural complications after transsphenoidal surgery for removal of growth hormone (GH) secreting pituitary adenomas. Methods: Retrospective study of 58 patients who underwent microscopic transsphenoidal neurosurgery for GH secreting pituitary adenomas exeresis in Curitiba, Parana state, Brazil, between 1998 and 2011 by the same neurosurgeon. The Criteria for diagnosis of complications were clinical. Results: Five (8,6%) of the 58 patients who underwent transsphenoidal surgery developed postoperative anatomical complications, which was due to sixth cranial nerve palsy (3,4%), surgical wound infection (1,7%) and CSF fistula (3,4%). Conclusion: The rate of postoperative complications observed in the present study is likely the literature review. There is a drop in the rate of complications with increasing experience of the neurosurgeon.

Objective: to evaluate the hormone profiles of patients with pituitary adenomas operated on in Hospital das Clínicas, UniversidadeFederal de Goiás (HC-UFG), correlating them with the variables age, sex, and Knosp grade. Method: This is a retrospective quantitativestudy of medical records, including a total population of 20 patients diagnosed with pituitary adenomas operated on using the pureendoscopic endonasal transsphenoidal approach. The hormone profiles of the three types of pituitary adenoma prevalent in this institutionwere analyzed: nonfunctioning macroadenoma, growth hormone-secreting pituitary adenoma (acromegaly), and adrenocorticotropichormone-secreting pituitary adenoma (Cushing’s disease). Pre and postoperative hormone values were statistically paired with thevariables selected. Results: The global levels of the specific hormones of each disease decreased after surgery. However, no statisticalsignificance was found between the variables selected in this study and the pre and postoperative hormone values. Conclusion:The main surgical goal, the specific hormones decrease, was achieved in all the surgeries performed. Analyzing the relationshipbetween the variables and the hormone profiles, we conclude that age, sex, and Knosp grade did not influence the results obtained.

Abstract We retrospectively analyzed surgical outcomes of transsphenoidal surgery for pituitary adenomas. A total of 366 consecutive patients undergoing transsphenoidal surgery for a pituitary adenoma from December 1990 through May 2017 were included in this study. The most common tumor type was nonfunctioning pituitary adenoma (NFPA) (63.7%), followed by prolactin-secreting adenoma (20.5%), growth hormone-secreting adenoma (13.4%), adrenocorticotropin-secreting adenoma (2.2%), and thyrotropin-secreting adenoma (0.2%). This cohort study consisted of 164 male and 202 female patients. The median patients age was 48 years. The median follow-up duration was 63 months. Gross-total resection (GTR) was achieved in 83.7% of patients with a NFPA, 76% of prolactin-secreting adenomas, 71.4% of growth hormone-secreting adenomas, 75% of adrenocorticotropin-secreting adenomas, 100% of thyrotropin-secreting adenomas. There were 326 macroadenomas (69.1%). Surgical outcome was better in patients with microadenomas than in patients with macroadenomas (100% and 77.9%, respectively). Improvement of visual disturbances occurred in 148 (93.7%) of the 158 cases. Hormonal impairment by pituitary adenoma was improved in 105 (87.5%) of the 120 cases. There were 24 (8.2%) cases of recurrence after GTR; 17 patients underwent second surgery, 5 patients received radiotherapy, and the others continued conservative treatment. The median time interval between TSA and recurrence was 56 months. Postoperative cerebrospinal fluid leakage occurred in seven (1.9%) of 366 patients. Transsphenoidal surgery is an effective and safe treatment modality for most patients with pituitary adenoma.

Abstract Objectives Some complications have been more frequently reported after surgery for adrenocorticotropin hormone (ACTH)-secreting pituitary adenomas. We compared complication rates in patients with ACTH-secreting pituitary adenomas with those in patients with growth hormone secreting pituitary adenomas (growth hormone [GH] group) and nonfunctioning adenomas (nonfunctioning group). Design A comparative three-group analysis was performed for all patients who had endoscopic transsphenoidal surgery for pituitary adenomas at our center between January 2011 and May 2019. Variables included demographics, preoperative clinical and radiological characteristics, and postoperative radiological and endocrinological outcomes. Complications were divided into four categories: endocrinological, neurosurgical, medical, and ENT (ear–nose–throat)-related complications. Univariate and multivariate statistical analysis were performed. Results A total of 111 patients with pituitary adenomas and a mean age of 53.7 years were included (25 ACTH, 35 GH, and 51 nonfunctioning adenomas). Overall, 28 patients had microadenomas (25.2%) and 83 had macroadenomas (74.8%). Univariate statistical analysis for complications between groups showed no differences in neurosurgical and medical complications. Transient diabetes insipidus and postsurgical bacterial sinusitis were the only variables more frequently seen in the ACTH group (p = 0.01 and 0.04, respectively). Multivariate analysis for transient diabetes insipidus showed no differences between groups (p = 0.58). Conclusion Complication rates were similar in all three adenoma groups, particularly concerning major infections, thrombotic events, postoperative cerebrospinal fluid (CSF) leak, and transient diabetes insipidus. Transient diabetes insipidus was related with adenoma size and intraoperative CSF leak. Despite postoperative bacterial sinusitis was statistically higher in the ACTH group, this data should be interpreted with caution given the low number of patients with this complication.

Object The aim of this study was to determine the preoperative predictors of the extent of resection and endocrinological remission following endonasal endoscopic removal of growth hormone (GH)-secreting pituitary adenomas. Methods The authors analyzed a prospectively collected database of 24 consecutive acromegalic patients who underwent endoscopic endonasal transsphenoidal surgery. The extent of resection was evaluated on postoperative contrast-enhanced MR imaging. Endocrinological remission was defined as normal insulin-like growth factor I (IGFI) serum levels and either a nadir GH level of < 0.4 ng/ml after an oral glucose load or a basal GH serum level < 1 ng/ml. Results The majority of acromegalic patients (83%) had macroadenomas > 1 cm in maximum diameter. Gross-total resection was achieved in 17 (71%) of 24 patients. Notably, endoscopic transsphenoidal surgery allowed complete resection of all lesions without cavernous sinus invasion, regardless of the suprasellar extent. Biochemical remission was achieved in 11 (46%) of 24 patients. A smaller tumor volume and a postoperative reduction in GH serum levels were associated with a higher rate of biochemical cure (p < 0.05). During a 23-month follow-up period 5 patients (21%) underwent Gamma Knife treatment of any residual disease to further reduce excess GH production. Twenty patients (83%) reported significant relief of their symptoms, while 3 (13%) considered their symptoms stable. Two patients (8%) with large macroadenomas experienced postoperative panhypopituitarism, and 2 patients (8%) suffered from CSF leaks, which were treated with lumbar CSF diversion. Conclusions A purely endoscopic endonasal transsphenoidal adenoma resection leads to a high rate of gross-total tumor resection and endocrinological remission in acromegalic patients, even those harboring macroadenomas with wide suprasellar extension. Extended approaches and angled endoscopes are useful tools for increasing the extent of resection.

Abstract OBJECTIVE The goal of this study was to evaluate the efficacy and safety of transsphenoidal pituitary surgery for elderly patients, using improved techniques of the past decade. METHODS We retrospectively analyzed 32 surgically treated cases of clinically nonsecreting pituitary adenomas in patients more than 70 years of age (mean, 73.9 ± 3.4 yr). These patients were identified in a review of 982 patients with pituitary adenomas who were treated at University Hospital Eppendorf, Hamburg, between January 1991 and November 1999. RESULTS The mean preoperative duration of symptoms was 1.9 years (2 wk to 11 yr). The chiasmatic syndrome was present for 27 patients (84.4%). All patients underwent transsphenoidal surgery. Seven patients underwent reoperations. Preoperative assessments of anterior pituitary function revealed growth hormone deficiencies for 21 of 27 patients (77.8%), thyroid insufficiencies for 10 of 30 patients (33.3%), and adrenal insufficiencies for 13 of 29 patients (44.8%). Hypogonadism and hyperprolactinemia were observed for 76.7% and 46.9% of the patients, respectively. All tumors were macroadenomas, ranging from 18 to 50 mm (average, 33.6 mm) in size, including 7 enclosed and 25 invasive adenomas. Complete microscopic tumor resection was achieved in 24 cases, and subtotal removal was performed in 8 cases. There were no severe perioperative complications. In the cases involving hyperprolactinemia, serum prolactin levels were normalized for 8 of 11 patients (72.7%). Normal thyroid function was recovered for 1 of 10 patients (10.0%) with preoperative hypothyroidism. However, growth hormone or adrenal insufficiencies persisted for all patients with preoperative insufficiencies. Visual disturbances were improved for 19 of 23 patients (82.6%). All patients recovered well after surgery, with an average hospital stay of 16.3 days. Histological and immunohistochemical studies demonstrated gonadotroph adenomas in 56.7% of cases, null-cell adenomas in 26.7%, and oncocytomas in 13.3%. CONCLUSION Surgical treatment of nonsecreting pituitary adenomas causing visual disturbances is standard, even for elderly patients. In this series, transsphenoidal surgery was a safe procedure, with minimal morbidity and excellent tolerance. Age alone is not a contraindication for active treatment, particularly with transsphenoidal surgery.
