Background: Refractory Cushing disease (CD) is associated with considerable morbidity and mortality. Bilateral adrenalectomy (BA) offers effective permanent treatment. Both open and laparoscopic approaches have been used, but longterm comparisons are few.
Study design: We reviewed 40 consecutive BA for refractory CD from 1995 through 2007. Surgical results were evaluated. A Short Form-36 Quality-of-Life (QOL) survey was performed.
Results: Eighty-five percent (34 of 40) of patients were women, and median age was 41.9 years (range, 22.2 to 78.3 years). All had persistent CD after transsphenoidal operation (mean, 1.7; range, 1 to 3). Median followup was 5.0 years. Thirty-eight percent (15 of 40) of procedures were performed laparoscopically; 1 was converted to open. There were no operative or 30-day mortalities, and there was 1 90-day mortality. Morbidities occurred in 7 of 40 (18%) patients. Median length of stay was shorter in the laparoscopic group (4 versus 6 days; p < 0.001). All patients achieved clinical reversal of hypercortisolism, including the 5 (13%) with ectopic adrenal tissue. Elevated serum ACTH (> 200 ng/mL) was present during followup in 33% (13 of 40). A QOL survey demonstrated 86% of patients felt good to excellent compared with 1 year pre-BA. Chronic fatigue was present most or all of the time in 46%, and patients were below population norms on 7 of 8 Short Form-36 scales. No difference was evident in QOL between laparoscopic and open adrenalectomy.
Conclusions: Our experience demonstrates excellent survival and clinical results, despite the inherent risk in patients with CD. There are persistent fatigue and QOL deficits that are not ameliorated by laparoscopic compared with open resection.
