Abstract:
Objective:Investigating the efficacy of unilateral adrenalectomy in treatment for primary pigmented nodular adrenocortical disease (PPNAD).Methods:Clinical data of 26 patients with PPNAD treated in our hospital from January 2013 to June 2023 was retrospectively analyzed.There were 11 males and 15 females, with an average age of (19.4±4.7) years. 25 cases presented with typical Cushing's syndrome, and 16 cases were diagnosed with Carney's syndrome. PRKAR1A gene mutation detected in 8 out of 10 cases. CT showed multiple small nodules on bilateral adrenal glands in 14 cases, unilateral small nodules or mild thickening with normal contralateral glands in 8 cases, and no obvious abnormalities in 4 cases. All patients showed autonomous oversecretion of cortisol by endocrine laboratory tests, with a median 24 h-UFC of 408.35 (334.28, 800.78) μg/24 h and decreased level of adrenocorticotropic hormone. All 26 patients underwent laparoscopic unilateral adrenalectomy, with left side adrenalectomy in 8 cases and right side adrenalectomy in 18 cases.Results:The average surgical duration was (85.2±28.7) minutes, with intraoperative blood loss <50 ml in all cases. The median time to drainage tube removal post-operation was 3 (2, 3) days. One patient developed a postoperative pulmonary infection, and 3 patients required postoperative hormone replacement therapy. The median follow-up duration was 64 (31.5, 103.8) months, and all patients showed alleviation of Cushing syndrome clinical manifestations after operations. 19 patients (73.1%) had their 24 h-UFC levels normalized to a median of 42.0 (22.4, 58.3) μg/24 h within 8.5 (5, 46) days post-surgery. 7 patients (26.9%) did not achieve normal 24 h-UFC levels, yet experienced an average reduction of (73.2±10.4)%. 13 patients (50.0%) did not experience recurrence, with a median follow-up of 51 (7, 89.5) months, including two cases without recurrence at 10 years post-surgery. 13 patients showed recurrent increase in postoperative cortisol levels, with a median of 225.6 (188.9, 397.2) μg/24 h. The median time to increased 24 h-UFC post-surgery was 27 (13.5, 50.5) months, with the longest duration reaching 104 months. Among these, 9 cases exhibited clinical signs and symptoms of recurrence, while 4 cases did not. Of the 13 patients with recurrence, 9 underwent contralateral adrenalectomy or subtotal resection, while 4 were observed with follow-up.Conclusions:Unilateral adrenalectomy could be a surgical treatment option for PPNAD. Despite the recurrence in some patients postoperatively, unilateral adrenalectomy could effectively and rapidly reduce cortisol levels in PPNAD patients and alleviate the clinical manifestations of Cushing syndrome.
