Minimally Invasive Partial vs. Total Adrenalectomy for the Treatment of Unilateral Primary Aldosteronism: A Systematic Review and Meta-Analysis

Rocco Simone Flammia et al. J Clin Med. .

Abstract

Background: This systematic review and metanalysis was conducted to assess differences between perioperative and functional outcomes in patients undergoing minimally-invasive partial (mi-PA) and total adrenalectomy (mi-TA) for unilateral primary aldosteronism (uPHA).

Material and methods: Multiple scientific databases (PUBMED, Web of Science, and Cochrane Library) were searched up to November 2021 for surgical series comparing mi-PA vs. mi-TA for uPHA according to the PRISMA statement. Primary outcomes of interest were perioperative and functional outcomes.

Results: Overall, a total of 802 patients from six eligible studies were identified, with mi-PA and mi-TA performed in 40.4% (n = 324) and 59.6% (n = 478) of cases, respectively. No differences were recorded between the two groups according to number of transfusions, EBL and Clavien-Dindo complications ≥2. Similarly, no differences in clinical success, persistence of postoperative hypokalemia and improvement in HTN were reported between mi-PA and mi-TA.

Conclusions: In a uPHA setting, mi-PA and mi-TA provide comparable perioperative and functional outcomes despite the use of mi-PA remains limited to patients with small adenoma size, or hereditary/bilateral disease. Due to limited use of standardized reporting criteria in most of current series, the quest for a superiority of mi-PA over mi-TA in the treatment of uPHA still remains open.

Keywords: Conn’s syndrome; PASO; partial adrenalectomy; total adrenalectomy; unilateral primary aldosteronism.

Cumulative analysis of eligible studies comparing mi-PA vs. mi-TA in terms of (a) operative time, (b) transfusion rate, (c) blood loss, (d) hospital stay, (e) overall complication, and (f) Clavien–Dindo ≥ 2. IV = inverse variance; SD = standard deviation; CI = confidence interval; M–H = Mantel–Haenszel. Each studies is represented by a square incorporating confidence intervals represented by horizontal lines. The area of each square is proportional to the study’s weight in the meta-analysis. The meta-analysed measure of effect is plotted as a diamond with lateral points indicating confidence intervals.
