Assessment of the diagnostic efficacy of radiological and functional evaluation of primary adrenal mass and its' surgical outcomes.

INTRODUCTION

Objective of this study was to assess the diagnostic efficacy of the most commonly used radiological evaluation in form of contrast enhanced computed tomography of abdomen with adrenal protocol, basic functional evaluation and surgical outcomes of primary adrenal masses.

MATERIAL AND

METHODS

We have retrospectively analysed the institutional records of 108, patients admitted from August 2017 to September 2023, who had underwent surgical intervention for their adrenal mass after thorough evaluation and stabilization.

RESULTS

Flank pain was the most common symptoms in 44 (40.74%) patients. Non-functional adrenal adenoma was found in 36 (33.33%) patients. Pheochromocytoma was the most the common functional adrenal mass found in 24 (22.22%) patients. CECT abdomen had suggested features of malignancy in 16(14.81%) patients. In final histopathological report 26(24.07%) patients had pheochromocytoma and 12 (11.11%) patients had adrenocortical carcinoma. CECT abdomen had sensitivity of 75%, specificity of 95.6%. Plasma free metanephrines and normetanephrine analysis had shown sensitivity of 90%, specificity of 92.86%, aldosterone to renin ratio had sensitivity of 92%, specificity of 100%. Sensitivity and specificity of the low-dose dexamethasone suppression test and plasma dehydroepiandrosterone was 100% in our study. Eighty patients (74.07%) were operated with laparoscopic adrenalectomy, 20 (18.52%) patients with open adrenalectomy. Eight patients (7.41%) were converted from laparoscopic to open. Laparoscopic approach had significantly lesser mean operating time, lesser blood loss, lesser hospitalization and lesser post-operative complications.

CONCLUSION

Radiological analysis and functional analysis has shown good sensitivity and high specificity. Laparoscopic approach has advantage of lesser operative time, lesser hospitalization and lesser post-operative complications.
