Background:

Surgical approaches to the sellar region have been a challenge for the neurosurgeon. With the introduction of the endoscopic technique, surgical trauma has been minimized, however it is not free of complications.

Objective:

To describe our institutional experience in patients undergoing resection of pituitary macroadenomas by endoscopic-assisted microsurgical approach, with emphasis on the resulting complications.

Method:

We reviewed the electronic files of 17 patients who underwent this procedure consecutively between 2017 and 2018, collecting variables such as age, sex, imaging classification, time of diagnosis at the time of surgery, postoperative complications and recurrence.

Results:

The average age of the patients was 45.23 years, with 70.59% women. Radiologically, grade 2 Knosp predominated (47.05%). The main complication was transient diabetes insipidus (23.52%) followed by cerebrospinal fluid fistula (11.76%).

Conclusions:

The endoscopic-assisted microsurgical approach has proven to be a valuable resource for treating pituitary macroadenomas, however it presents variable degrees of complications, which requires the acquisition of skills for the use of the endoscope, adequate preoperative planning, and multidisciplinary joint management in order to avoid them.
