Introduction: Acromegaly prevalence is 35-70 / million. Transsphenoidal surgery is the first-line treatment, with a remission rate of 80% for microadenomas and 50% for macroadenomas. Our aim was to evaluate the surgical results in Córdoba and determine predictive remission factors due to the lack of records., Methods: Retrospective-descriptive study of patients with surgery as the first therapeutic line. Remission criteria: IGF1 normalization for age/sex, with GH ≤1.0 g/L. Test X2 and Fisher's exact test with p<0.05., Results: 38 patients were included: 61% women and 39% men; Average age 45 years. Most frequent chief complaint: headache and acral growth (26%), visual disturbances (20%). Macroadenomas were the 84% of the tumors. Of 37 patients, 54% underwent microscopic surgery, 38% endoscopic and 8% transcranial. The 29% of patients showed post-operative complications and diabetes insipidus was the most frequent (10%). The percentage of them was: 33% transcranial surgery, 29% endoscopic and 25% microscopic (p = 0.557). The biochemical remission at 6 months was 34% and at 12 months 55% (p= 0.0001). No significant differences between the endoscopic and microscopic approach (p = 0.071). Of 36 patients, 31% showed complete tumor resection. The subjective clinical improvement was 88%. There weren´t predictive remission factors with significant differences., Conclusion: The surgical biochemical remission was similar to the bibliography. We didn´t find predictive remission factors but a larger number of patients could modify these results., (Universidad Nacional de Córdoba.)
