Open versus laparoscopic simultaneous bilateral adrenalectomy.

OBJECTIVES: To compare our experience with synchronous bilateral adrenalectomy using laparoscopic and open techniques. Laparoscopic adrenalectomy has become the reference standard for management of benign unilateral adrenal pathologic findings. METHODS: This was a nonrandomized retrospective chart review of 12 known patients who underwent simultaneous bilateral adrenalectomy, comparing five laparoscopic and seven open procedures. One urologic surgeon performed all laparoscopic cases, and one general surgeon performed all open procedures. RESULTS: All patients had Cushing's disease or syndrome. The average patient age was 47.4 years (range 24 to 71) and 42.4 years (range 19 to 70), with an average body mass index of 38.2 kg/m2 and 36.0 kg/m2 for the laparoscopic and open groups, respectively. The operating time was on average 60 minutes longer for the laparoscopic group. No open conversions were necessary. The median blood loss (100 versus 500 mL, P < 0.01) and hematocrit drop (8.5% versus 12.6%, P = 0.05) were lower for the laparoscopic group. The transfusion rates and hospital stay trended lower in the laparoscopic group (20% versus 57% and 3 versus 8.5 days, respectively). Specimen weights for both the right and left glands trended larger for the laparoscopic group. The complication rates were similar between groups at 60% for the laparoscopic versus 71% for the open groups. CONCLUSIONS: Simultaneous laparoscopic bilateral adrenalectomy is safe and effective. Compared with the open approach, it resulted in decreased blood loss, lower transfusion rate, and a trend toward a shorter hospital stay, although the operating time was longer. The laparoscopic approach should be the treatment of choice for bilateral adrenalectomy.

Multiple endocrine neoplasia 2A syndrome presenting as peripartum cardiomyopathy due to catecholamine excess.

We report the case of a 24-year-old female with a history of medullary thyroid carcinoma who presented at 38 weeks gestation with acute chest pain and shortness of breath. She was found to be in pulmonary edema and respiratory failure. An emergency cesarean section was performed. Subsequently, an echocardiogram revealed an ejection fraction of 10%. After medical therapy with digoxin, milrinone, captopril and diuretics, her condition improved rapidly and a repeat echocardiogram showed that the left ventricular function had normalized. Diagnosis of pheochromocytoma was made by urine and plasma catecholamine measurements. Magnetic resonance imaging revealed a 3.7 cm left adrenal mass. Increased uptake activity was seen in the same region by an (131)I-metaiodobenzylguanidine (MIBG) scan. The patient underwent successful surgical resection of the pheochromocytoma. Subsequent DNA analysis revealed that the patient had a mutation of the RET proto-oncogene. The same mutation was also found in several of her family members. In summary, we report a case of multiple endocrine neoplasia 2A presenting as peripartum cardiomyopathy and cardiovascular collapse. Pheochromocytoma should be considered as a potential cause of peripartum cardiomyopathy.

Pitfalls of intraoperative quick parathyroid hormone monitoring and gamma probe localization in surgery for primary hyperparathyroidism.

HYPOTHESIS: Intraoperative quick parathyroid hormone (qPTH) monitoring and gamma probe (GP) localization greatly aid the surgeon. DESIGN: Prospective case series of patients undergoing parathyroidectomy (PTX) with preoperative localization studies, operative data (including intraoperative qPTH values and GP localization), and outcomes. Follow-up was complete (mean, 4.2 months). SETTING: University teaching hospital. PATIENTS: We studied 57 consecutive patients with primary hyperparathyroidism from December 1, 1999, through November 30, 2000. Of these, 51 underwent first-time PTX, and 6, reoperative PTX (rePTX). MAIN OUTCOME MEASURES: Cure rate and morbidity after PTX or rePTX; sensitivity and accuracy of preoperative localization studies; prediction of cure from results of qPTH monitoring (comparing Nichols [>50% fall from the highest baseline level and lower than the lowest baseline] or normal-limit [>50% fall from first baseline level and lower than upper limit of the reference range] criteria); and value of GP localization. RESULTS: Patients were cured in 50 (98%) of 51 PTX and 6 (100%) of 6 rePTX for single adenomas (n = 49), double adenomas (n = 4), and multigland hyperplasia (n = 3). Nichols criteria for qPTH monitoring correctly categorized 45 (92%) of 49 cured single adenomas 10 minutes after excision. Only 35 (71%) of these adenomas were correctly categorized as cured by means of the normal-limit criteria. In double adenomas, both sets of criteria in the 10-minute samples indicated unresected glands in only 2 of 4 cases. Preoperative sestamibi parathyroid scans correctly localized 38 (76%) of 50 single adenomas. The GP was used in 54 of 57 cases. All adenomas measured greater than 20% of background ex vivo, but 6 thyroid nodules also measured greater than 20% ex vivo. In double adenomas, the GP helped locate the second adenoma in only 1 of 4 cases. The GP was graded as crucial in 2 cases with dense scar (both rePTX), helpful in 12 (22%) of 54 cases (particularly in retroesophageal glands), confirmatory in 32 (59%), and not helpful in 8 (15%). The GP helped localize 3 (43%) of 7 glands not seen on sestamibi parathyroid scans. CONCLUSIONS: Intraoperative qPTH monitoring confirmed cure in most cases. For single adenomas, use of the Nichols criteria for qPTH assessment allowed more accurate and faster confirmation than the normal-limit criteria. The GP was less useful but was crucial in 2 rePTX cases; it was not specific for parathyroid tissue. Both techniques have potential pitfalls that could result in surgical failure.

Clinical case seminar: Riedel's thyroiditis: report of a case complicated by spontaneous hypoparathyroidism, recurrent laryngeal nerve injury, and Horner's syndrome.

A 42-yr-old woman presented with hyperthyroidism and a large, firm, irregular goiter. Within a few weeks she became hypothyroid. Five months later she developed increasingly severe neck pain and compressive symptoms. The goiter had become rock hard. A fine needle aspiration biopsy showed features of chronic thyroiditis and fibrosis. She partially responded to a course of glucocorticoids. Tamoxifen was added, with marked improvement in goiter size and pain. Both medications were tapered off. Two months later the patient experienced paresthesias of the fingertips, perioral numbness, and a seizure. She was found to have spontaneous primary hypoparathyroidism. Three months later the patient became hoarse and experienced difficulty in breathing. She was found to have a massively enlarged thyroid with compression of the right internal jugular vein and encasement of the right carotid artery as well as tracheal narrowing. She also had right vocal cord paralysis due to recurrent laryngeal nerve involvement. Because of airway compromise, an emergency isthmusectomy was performed, and the patient was given a postoperative course of glucocorticoids with gradual improvement. Postoperative diagnosis was Riedel's thyroiditis. Two months later she presented with near-syncope and was found to have bradycardia, hypotension, and right Horner's syndrome, presumably due to compression of the right carotid sheath. She was given i.v. glucocorticoids and tamoxifen. Six months later and 18 months after her initial presentation, the patient is doing remarkably well. Her goiter has regressed by more than 50%, and she no longer has any pain or difficulty breathing. She remains a little hoarse and has persistent hypothyroidism and hypoparathyroidism. She is taking prednisone (5 mg, this is being tapered very slowly) and tamoxifen (20 mg) daily. This case illustrates the protean manifestations of Riedel's thyroiditis, a rare but fascinating disease. The epidemiology of this disease, its pathophysiology and complications, and the roles of surgery and medical therapy are reviewed.
