Analysis of operative efficacy for giant pituitary adenoma

BMC Surgery

Table 4 Comparison of tumor resection rate with postoperative hormone (n = 10) and postoperative visual acuity (n = 24) improvement

Improvement	Postoperative hormone^a		Postoperative visual acuity^b
Improvement	Unimproved	Improved	Remained	Improved
Number of cases	2	8	9	15
Average tumor resection rate (%)	72.3	83.5	60.4*	79.5

Note: ^aComparison of tumor resection rate in hormone levels in 10 patients with functional pituitary adenomas before and 24 hours after surgery. ^bComparison of tumor resection rate in visual acuity in 24 patients with decreased visual acuity before and 24 hours after surgery.
*P < 0.05, average tumor resection rate with remained visual acuity vs. average tumor resection rate with improved visual acuity, Mann–Whitney U test.
