Purpose: Primary aldosteronism due to an adrenal cortical adenoma is a surgically curable disease. However, hypertension is known to persist postoperatively in many patients. The aim of this study was to determine the factors influencing the long-term outcome of blood pressure after an adrenalectomy for a primary aldosteronism and to evaluate the changing pattern of renin and aldosterone. Methods: Forty-two cases of primary aldosteronism, which were operated on and followed up at the Department of Surgery, Seoul National University Hospital from January 1986 to June 2001 were included in this study. The subjects were classified into a normotensive group and a hypertensive group and the two groups were compared according to the clinical, biochemical and pathological parameters. Results: After surgery, the aldosterone concentration was decreased and the plasma renin activity was increased. During a mean follow-up period of 28 months, 31 patients (73.8%) had a normal blood pressure without an antihypertensive treatment. The significant risk factors for persistent hypertension were a family history of hypertension, a long duration of preoperative hypertension, a poor response of preoperative spironolactone. The hypertensive group had a higher level of postoperative plasma renin activity and an aldosterone concentration in the long-term follow-up period after surgery. Conclusion: A family history of hypertension, the duration of hypertension and the response to spironolactone were factors influencing persistent hypertension after surgery for a primary aldosteronism. A high level of plasma renin activity and aldosterone during the follow-up period is related to the persistent hypertension. Therefore, early detection and surgery for a primary aldosteronism would reduce the preoperative cardiovascular changes and improve the postoperative outcome. (Korean J Endocrine Surg 2003;3:141-146)

Purpose: Insulinoma is a rare disease for which early diagnosis followed by proper surgical management provides a chance for cure. Analyses of clinicopathological features of patients can help optimize the surgical approach in the treatment of insulinoma. Methods: The records of 13 patients (seven male, six female mean age 44.3 years; age range 17∼62 years) who were diagnosed clinically and pathologically with insulinoma and who underwent surgery between March 1997 and April 2007 at the Department of Surgery, Seoul National University Hospital. Hospital in English please were retrospectively examined. Results: All patients had findings compatible with Whipple's triad. Mean fasting blood sugar was 40.5 mg/dl, serum insulin level was 33.5ՌU/ml, and insulin-to-glucose ratio was 0.6. A prolonged starvation test was performed on six patients. Tumors were localized in 10 patients with a computed tomography (CT) scan and in three patients with CT angiography. Five tumors were located in the pancreas head and uncinate process, five in the body, and four at the body-tail border and tail. Patients underwent resection of tumorby enucleation, distal pancreatectomy, pylorus-preserving pancreaticoduodenectomy, laparoscopic distal pancreatectomy, and duodenum-preserving resection of pancreas head. Four immediate postoperative complications (fluid collection, pancreatic fistula, delayed gastric emptying) occurred. No symptoms or recurrences were apparent during the median 15 month follow-up. Conclusion: Insulinoma is difficult to diagnose correctly without a prolonged duration of symptoms. Localization of insulinoma can be aided by a CT scan and/or CT angiography. Less aggressive operative procedures such as simple enucleation might be a sufficient and feasible procedure for curative resection of benign insulinomas. (Korean J Endocrine Surg 2010;10:99-105)

Eighteen patients with primary hyperparathyroidism were treated by one of the authors (SKO) from 1981 through 1988 at the Department of Surgery, Seoul National University Hospital and the data were analyzed retrospectively. Eighteen patients comprised 6 males and 12 females, with the male to female ratio of 1 to 2. The age distribution was between 18 and 64 years. The chief complaints were associated with skeletal symptoms in 9 urinary symptoms in 5, and neurologic manifestation in 1 patient. There were 3 patients with asymptomatic hypercalcemia. All patients showed hypercalcemia and hypophosphatemia was found in 11 patients. Serum PTH level was elevated in 13 cases. performing preoperative localization with computed tomorgam, ultrasonogram and thallium-technetium subtraction scan, positive localization was made in 62.5% (10/16), 53.8% (7/13) and 85.7% (12/14), respectively. one patient, angiography and selective venous sampling were peformed and positive localization was made. All patients were treated by surgery. There were 17 patients with solitary adenoma and one with double tumors. Pathologic findings revealed adenoma of the parathyroid in all patients except one which was proved later to be carcinoma. There were no recurrent cases except one with carcinoma. There were no postoperative complications. primary hyperparathyroidism is a very rare disease in Korea. Causes of primary hyperparathyroidism in our study was confined to tumors of the parathyroid, such as adenoma and carcinoma.There was no hyperplasia causing primary hyperparathyroidism. Thallium-technetium subtraction scan was proved to be the best method for localization of the parathyroid tumors. Excision of the tumor with involved parathyroid followed by frozen-section biopsy of the univolved parathyroid was the best way to treat primary hyperparathyroidism in our study.
