Abstract
Growth hormone (GH) hypersecretion from a pituitary adenoma results in acromegaly, an endocrinological disorder with multiple systemic manifestations that presents several unique challenges in terms of perioperative management and long term outcomes. Current guidelines provide stringent criteria for determining biochemical remission, necessitating an aggressive approach to management. Despite the development of several non-surgical therapies, transsphenoidal surgery, the endoscopic approach in particular, remains the primary line of treatment for rapid normalization of GH and Insulin-like growth factor with a low incidence of perioperative morbidity. Tumor size and invasiveness are important factors predicting surgical outcomes with better rates of postoperative remission seen in smaller and non-invasive tumors. Postoperative remission rates reported in literature with the 2020 consensus criteria vary from 30 to 85% probably reflecting varying prevalence rates of invasive tumors. Thus, a significant proportion of patients fail to achieve remission after surgery for whom treatment options for residual disease must be carefully considered. This review article discusses the surgical management of acromegaly and provides a summary of contemporary outcomes and current treatment controversies.
