OBJECTIVE: To study the effect of endoscopic-assisted keyhole operation (EAKO) on treating @entity428 and the value of our patent dissector applied during the operation. METHODS: A total of 25 @entity1 with @entity428 underwent endoscopic-assisted keyhole evacuation, during which, the viewing dissector, which had recently achieved national patent, was connected to the tip of endoscope and used to help dissect @entity1410 . The outcome of this procedure were compared with those of 22 comparable cases undergone conventional surgical treatment (large or smaller craniotomy). The items for comparison included the volume of remaining @entity1410 , the duration of operation, postsurgical Glasgow @entity772 Scale (GCS) and Glasgow Outcome Scale (GOS). RESULTS: Remaining @entity1410 was ascertained 48 h after operation with the use of computerized tomography (CT) scans. In the case of EAKO, nearly complete evacuation (> 84%) was achieved in 21 cases; GCS was evaluated at 7 d postsurgery resulting in GCS > 12 in 9 @entity1 , GCS 9 - 12 in 12 @entity1 and GCS < 9 in 4 @entity1 . The follow-up period ranged from 6 to 21 mon. GOS was estimated at half a year and good recovery rate as defined by GOS was assigned to 76% of the EAKO @entity1 . There are significant differences in the volumes of remaining @entity1410 and the duration of operation between the EAKO and craniotomy group (P < 0.05). In addition, better clinical outcomes were obtained in EAKO. CONCLUSION: EAKO has the advantage of being minimally invasive, improving surgical results and the prognosis of hypertensive @entity2075 @entity1 . We conclude that keyhole operation is a safe, effective alternative for removal of hypertensive @entity2075 , particularly during acute stages.
