Long-Term Outcomes and Complications from Endoscopic Versus Microscopic Transsphenoidal Surgery for Cushing?s Disease: A 15-Year Single-Center Study

BACKGROUND: Endoscopic endonasal surgery is the many centers; however, few studies compare the endoscopic and microscopic surgical approaches with regard to long-term follow-up. This single-center study aimed to compare the 2 techniques over 15 years. - METHODS: Medical records and magnetic resonance images from 40 patients with primary transsphenoidal Hospital between 2003 and 2018 were reviewed. 14 patients who underwent microscopic surgery and 26 patients who underwent endoscopic surgery were included in this study. RESULTS: In the microscopic group, 12 of 14 patients achieved endocrine remission, compared to 19 of 26 patients in the endoscopic group (n. s.). Three patients in each group developed a late recurrence. Complications were seen in 5 patients in the microscopic group and in 8 patients in the endoscopic group (n. s.). No serious complications, such as carotid artery damage, cerebrovascular fluid leakage, epistaxis, or meningitis, occurred in any group. The postoperative hospital stay was shorter in the endoscopic than in the microscopic group. CONCLUSIONS: Endoscopic endonasal surgery for Cushing's disease showed no difference in remission, recurrence, and complication rates compared to the microscopic approach. The endoscopic group had a shorter postoperative hospital stay than the microscopic group, which in part may be due to the minimal invasiveness of the endoscopic approach.

Automated summary

This study compared the outcomes of endoscopic and microscopic surgery for Cushing's disease over a 15-year period, finding no significant differences in remission, recurrence, and complication rates between the two techniques. However, the endoscopic group had a shorter postoperative hospital stay.
