| Abstract: | The authors have analyzed the results from 41 acromegalic patients who underwent transsphenoidal surgery. In 31 patients, postoperative growth hormone (GH) levels fell and remained below 10 ng/ml. This represents an endocrinological "cure" of 78%. In the remaining 10 cases, postoperative GH values have not stabilized below 10 ng/ml, although seven show some clinical improvement. The results were particularly good in those cases of localized adenomas, which allowed a selective removal while maintaining pituitary function within normal limits in 65.5% of cases. The postoperative GH level in this group fell and remained below 10 ng/ml in more than 90% of cases. Four patients required reoperation to normalize the GH levels which had not been sufficiently modified after the first operation; only one of them remained with plasma GH levels above normal limits. There were no deaths in this series. Rhinorrhea occurred as a postsurgical complication in four cases. In three this disappeared with bed rest and lumbar drainage; in the other, surgical repair was necessary. The occurrence of surgical complications has decreased as our experience has increased, and the need for reoperation has been unusual after the first year of our study. |
