Objective: To obtain objective evidence that the use of endoscopy in the surgical management of pituitary tumors improves intraoperative visualization and significantly impacts operative outcomes. Design: Case series of pituitary adenomas treated surgically by endoscope-assisted microscopic resection. Setting: University-affiliated tertiary care medical center. Patients: Consecutive sample of 9 patients referred for surgical management of pituitary adenoma. Interventions: Each patient underwent transseptal transsphenoidal microscopic tumor resection. The procedure was modified by the use of intrasellar endoscopy as an adjunctive imaging modality. Following complete microscopic resection of tumor, rigid 0 degrees and 30 degrees 4.0-mm endoscopes were used to conduct a final survey of the sellar and parasellar spaces. Residual tumor fragments identified during this endoscopic examination were removed. Outcome Measures: Endoscopes were thought to have a significant impact on surgical therapy in cases where residual tumor that was not detected microscopically was identified and removed during endoscopic examination. Analysis of each case included correlation between intraoperative findings and retrospective review of dictated operative reports and intraoperative videotape. Results: Three of the patients with macroadenoma (33% of total, 43% of macroadenoma cases) had tumor fragments that were only identified and removed endoscopically. Conclusions: Endoscopy provides distinct advantages over microscopy in imaging intrasellar and parasellar structures during pituitary tumor resection. These data support the numerous anecdotal accounts of the usefulness of pituitary endoscopy and are consistent with the small amount of objective evidence offered on the subject.
