Abstract
Untreated hypercortisolism is a fatal state, causing functional disability. Even after successful treatment, clinical recovery is slower than the biochemical one, but data about clinical results, well-being and working capacity after surgery are scarce. This retrospective study aimed at evaluating the long-term outcome of patients after adrenalectomy for ACTH-independent hypercortisolism by the analysis of the clinical results, the survival and the subjective well-being status after surgery. Clinical data in 50 patients suffering from ACTH-independent hypercortisolism and treated between 1980 and 2000 by unilateral adrenalectomy were recorded. At a mean follow-up of 134 months, 3 patients were dead. All the surviving patients were asked to self estimate the physical and psychological recovery after surgery. After surgery, 100% of patients were biochemically cured. A clinical recovery was observed in most cases: obesity in 59.6% and hypertension in 57.5%. Bone mass density (BMD) significantly improved (+20%). The long-term mortality rate did not differ from normal population. Subjectively, a full recovery was confirmed by 95.6% of the surviving patients; it was correlated with the subjective feeling of physical recovery (95.6%) and regained working ability (93.3%). Despite of biochemical and clinical cure, no subjective improvement of the psychological conditions was observed in 26.7% of cases. At long-term follow-up, most objective symptoms of Cushing’s syndrome (CS) disappear; subjective health and working ability are often regained, but a psychological impairment could persist in spite of a successful treatment.
