Laparoscopic adrenalectomy is performed through small incisions the size of a fingernail or thumbnail on the abdomen to remove adrenal glands that produce excess hormones or have a suspicion for cancer. Adrenal glands that produce excess hormones include aldosteronomas, pheochromocytomas, and cortisol producing adenomas. Each excess hormone produce different symptoms, but difficult to control hypertension is one common symptom. Any adrenal tumor that is four centimeters or larger should be removed, regardless of whether they produce excess hormones or not, to rule out the possibility of cancer. Adrenal tumors always need to be worked up for excess hormones and if they produce excess hormones patients usually need to have important preoperative treatment before surgery. After laparascopic adrenalectomy patients frequently leave the hospital one or two days later, and can return to work in two weeks.
