Laparoscopic sleeve gastrectomy followed by laparoscopic adrenalectomy for patients with obesity and primary aldosteronism: Report of two patients.

Primary aldosteronism (PA) is the most frequent cause of secondary hypertension. Surgical treatment of unilateral PA usually resolves excessive aldosterone secretion. Obesity is an independent factor for postoperative persistent hypertension for patients with unilateral PA. Laparoscopic sleeve gastrectomy has become popular due to its efficacy in resolving obesity. A specific strategy might to be needed for patients with unilateral PA and obesity. Two males with PA and obesity (Body Mass Index: BMIs of 35.9 and 39.0, respectively) were referred for evaluation. Both patients had hypertension caused by PA and obesity. We performed laparoscopic sleeve gastrectomy (LSG) prior to adrenalectomy to avoid persistent postoperative hypertension and perioperative obesity related comorbidities. LSG could lead to decreasing of BMIs to 27.7 and 32.1. Comorbidities associated with obesity were also resolved in both patients. Laparoscopic adrenalectomy was then safely performed in these two patients with PA. Patients with PA developing resistant hypertension were estimated to be 20 % of those who underwent adrenalectomy. Decreased BMI can be an independent preoperative determinant for successful outcome after adrenalectomy regarding hypertension. We need to review with special care the preoperative BMI and the nature of hypertension before performing surgery on patients with unilateral PA. A successful strategy was used to treat two obese patients with unilateral PA who underwent laparoscopic adrenalectomy after LSG to minimize complications associated with obesity-related comorbidities. • A successful strategy for obese patients with unilateral aldosteronism. • Obesity can cause persistent hypertension after adrenalectomy. • Laparoscopic sleeve gastrectomy has shown efficacy in resolving obesity. • Initial sleeve gastrectomy followed by laparoscopic adrenalectomy was performed.
