Outcomes after laparoscopic adrenalectomy for unilateral primary aldosteronism.

Unilateral primary aldosteronism (PA) is the most common surgically correctable cause of hypertension. Determination of success after laparoscopic adrenalectomy (LA) is limited by the lack of standardized criteria. We sought to evaluate the surgical recurrence and functional outcomes of LA in patients with Conn's syndrome applying the primary aldosteronism surgical outcome (PASO) Criteria. Descriptive observational analysis of patients treated with LA due to confirmed u nilateral Conn's syndrome between May 2007 and August 2020: Twenty patients were included in the cohort; 16 patients had TLA and other four PLA [58% male, median age 47 (IQR: 44-59.5) years and median follow-up of 64 (IQR: 2-156) ] months. Median tumor size was 1.2 (0.8-1.8) cm. No conversions to open surgery were recorded and the overall morbidity of the series was 1/20. No surgical or biochemical recurrence was observed. Five patients were excluded from the analysis of functional results due to lack of follow-up. According to the PASO criteria, complete, partial, and no success were observed in 8/15, 6/15, and 1/15, respectively. The surgical treatment of the disease is supported by the literature, and we were able to reproduce the results of other series. The use of standardized and reproducible criteria to assess its functional results would be essential for a more complete and integrated evaluation of adrenal surgery.
