Neuroendoscopic and microscopic transsphenoidal approaches have been widely used in the resection of nonfunctional pituitary adenomas. However, the clinical efficacy in neuroendoscopic and microscopic surgery is still controversial. AIM To explore the clinical efficacy of neuroendoscopic and microscopic transsphenoidal approach for resection of nonfunctional pituitary adenomas. METHODS We retrospectively analyzed 251 patients with nonfunctional pituitary adenomas;138 underwent neuroendoscopic surgery via transsphenoidal approach, and 113 underwent microscopic surgery via transsphenoidal approach between July 2010 and September 2015. All patients were followed up for > 6 mo. Gender, age, course of disease, tumor diameter, tumor location, and percentage of patients with headache, visual impairment, sexual dysfunction, and menstrual disorders were contrasted between the two groups to compare the difference of preoperative data. Cure rate, symptom improvement rate, recurrence rate, the postoperative hospital stay, operating time, intraoperative blood loss, and the incidence of postoperative complications were compared in order to evaluate the advantages and disadvantages of neuroendoscopic and microscopic surgery.RESULTS There was no significant difference in cure rate, symptom improvement rate, and recurrence rate between neuroendoscopy group and microscopy group (82.6% vs 85.8%, P > 0.05;90.6% vs 93.8%, P > 0.05;5.1% vs 9.7%, P > 0.05). In the neuroendoscopy group, the postoperative hospital stay was 8.4 ± 0.6 d;operating time was 167.2 ± 9.6 min;intraoperative blood loss was 83.4 ± 9.3 mL, and the rates of diabetes insipidus and electrolyte imbalance were 4.3% and 8.0%, respectively. The corresponding results in the microscopic group were 11.2 ± 0.6 d, 199.7 ± 9.3 min, 138.8 ± 13.6 mL, and 32.7% and 20.4%, respectively. There were significant differences in postoperative hospital stay, operating time, intraoperative blood loss, and the rates of diabetes insipidus and electrolyte imbalance between the two groups (P < 0.05). CONCLUSION Neuroendoscopic and microscopic transsphenoidal approaches have similar clinical efficacy for the resection of nonfunctional pituitary adenomas. Neuroendoscopic surgery reduces operating time, intraoperative bleeding, postoperative recovery, and complications.展开更多

The specific surgical methods are: a nasalspeculum is inserted slowly through the right nostril towards theanterior wall of the sphenoid sinus. A 1.5 cm incision is made intothe nasal mucosa in the right nasal cavity at the level of the middlenasal turbinate. By fracturing the bony septum, a space is formedbetween the bilateral nasal mucosa and the bony septum of thesphenoid sinus. Then, the inside of the sphenoid sinus is exposed.The remaining part of the bony septum, the anterior sphenoidsinus wall, and the sphenoid mucosa are gradually removed. Theanterior sphenoidotomy is less than 1.5 cm wide. After confirmingthe tumor by dural puncture, a cross incision of the dura is made,and the tumor is slowly removed by curette. The sella is usuallycollapsed and visible after the total tumor removal. When thetumor is resected satisfactorily, gelatin sponges are placed into theoperative cavity to stop bleeding.RESULTS Postoperative MRI scans revealed that among the 46cases, total resection of the tumor was achieved in 34 cases andsubtotal in 12. No deaths or disability occurred, and the hormonelevels of almost all patients improved. Signs of diabetes insipidusoccurred in 17, electrolyte disturbances in 5, and there were noreports of postoperative cerebrospinal fluid rhinorrhea.CONCLUSION The direct single nostril transsphenoidalapproach of continuous improvement has the advantages ofa convenient approach, simplified operation, safety and highefficiency.展开更多
