Repeat Transsphenoidal Surgery for the Treatment of Remaining or Recurring Pituitary Tumors in Acromegaly

Abstract

Repeat surgery can be performed safely with an approximately 60% long-term cure rate in this series. Reoperation should therefore be considered for persistent or recurrent disease in acromegalic patients in whom adjuvant therapy is not effective enough or cannot be accepted. The careful study of initial or preoperative magnetic resonance imaging and the use of micro-Doppler, endoscope, and eye movement monitoring device during surgery can help increase cure rate with a lower complication rate.
