ABSTRACT
Objective To compare the efficacy of neuroendoscopic vs microscopic endonasal transsphenoidal pituitary adenoma resection and effects on hormone levels and clinical symptoms. Methods A retrospective analysis was conducted on 211 cases with pituitary tumor resection patients from January 2012 to June 2016, of which 112 cases with endoscopic endonasal transsphenoidal pituitary tumor resection (group A), 99 cases with microscopic transsphenoidal pituitary tumor resection (group B), and operation related indexes, hormone variations before discharge and symptoms remission 24 weeks after operation were extracted and compared. Results Two groups of patients with different tumor resection extent (Z = 2.14, P = 0.032), group A achieved total resection rate was significantly higher than the group B (79.5% vs 67.7%) (P = 0.037); the operation time of group A was significantly longer than group B [(93.6 ± 26.7) vs (79.8 ± 20.2) min, t = 4.26, P = 0.000], group A with the mean hospitalization stay was significantly less than group B [(7.9 ± 2.5) vs (10.2 ± 4.3) d, t = 4.67, P = 0.000], postoperative complications of group A were significantly lower than those of group B (5.4% vs 14.1%, χ2 = 4.73, P = 0.030). Two groups of postoperative hormone levels decreased in different degree (Z = 2.42, P = 0.016), group A with hormone recovery rate before discharge was significantly higher than group B (82.2% vs 66.7%, χ2 = 6.09, P = 0.014), and decline on prolactinomas, ACTH adenoma, ghrelin hormone were significantly higher than group B [(43.2 ± 10.5) vs (33.5 ± 9.1) ng/ml, (26.0 ± 8.8) vs (20.2 ± 7.0) pmol/L, (11.0 ± 3.9) vs (8.7 ± 3.2) μg/L, t = 3.60, t = 2.65, t = 2.12, all P < 0.05]. There was no significant differences between the two groups in remission of clinical symptoms 24 weeks after operation (P > 0.05). Conclusion Neuroendoscopic endonasal transsphenoidal pituitary adenoma resection is more efficient and less operative complications compared with microscopic surgery, which is more conducive to the recovery of postoperative hormone levels.
