Abstract
The endoscopic technique is increasingly being used for the resection of pituitary adenomas. Its efficacy and safety have been generally accepted, but its impact on the quality of life of the patients treated has not been previously addressed. Most of the studies assessing the quality of life after long-term cure of pituitary adenomas suggest a significantly impaired quality of life (QoL) in all subgroups of pituitary tumours. In our study we analyse QoL data following endoscopic surgery, and attempt comparisons with normative and data from standard approaches. The validated health questionnaire SF-36 was sent to 80 patients who had undergone pure endoscopic resection of a pituitary adenoma. Fifty-four patients returned the completed questionnaire. Outcomes were compared with normative data for the Short Form-36 (SF-36) Heath survey for the general Canadian population. We also compared the results amongst different types of adenomas. We attempted a comparison to previous studies on quality of life for patients who underwent conventional trans-sphenoidal surgery. Our study suggests only minimal impairment of quality of life in patients after successful treatment of pituitary adenomas using the endoscopic approach. There were only very few differences in the perceived quality of life within the different subgroups of adenomas. There was a trend to improved scores in the endoscopic group compared with previous studies in patients treated by conventional approaches. Whilst our data suggest minimal impact on the quality of life for patients after endoscopic removal of pituitary adenomas, further studies with larger number of patients and longer follow-up are required to encourage this finding.
