✓ The authors combined a monopolar electrode and a suction/irrigation channel with a 0°, 4-mm Hopkins rigid telescope into a single multifunctional unit. This three-in-one instrument is inserted through a lightweight 7.5-mm outer sheath, which is fixed separately. A fourth instrument (for example, a balloon catheter or a biopsy forceps) can be introduced and manipulated independently with the other hand.

All endoscopic procedures were performed with a trephine to create a 15-mm craniotomy. After opening the dura mater, ventricles were tapped with a brain needle, which was followed by the insertion of the rigid scope for visualization. The telescope was then withdrawn momentarily; the outer sheath was introduced into the ventricle and fixed over the area of interest. The definitive procedure was then performed with ease by using the multifunctional three-inone instrument in one hand and a fourth instrument in the other hand.

This novel neuroendoscopic system has been used in clinical testing at the Vidyasagar Institute of Mental Health and Neurosciences since May 1998. Thus far, 83 neuroendoscopic procedures have been successfully performed with the aid of this instrumentation system, which has proven to be safe, versatile, and cost-effective, allowing a greater degree of freedom for the neurosurgeon.

Object

The aim of this study was to describe a new, minimally invasive technique for the endoscopic evacuation of intracerebral hematomas (ICHs) and the clinical and radiological outcomes in patients who underwent the procedure. The authors used a multifunctional three-in-one endoscopic instrument that combines a 0°, 4-mm rigid telescope, an irrigation cannula, and a cautery electrode.

Methods

In 13 patients a small keyhole craniotomy was made through noneloquent cortex to gain access to the hematoma. After opening the dura mater, a small cortical tunnel (~6 mm in diameter) was created using bipolar forceps and suction to enter into the clot. The three-in-one endoscope was then introduced to provide illumination and irrigation inside the cavity. The clot was safely aspirated under endoscopic vision and constant irrigation by performing microsurgical suction with the other hand. Hemostasis could be achieved using electrocautery and Surgicel. This technique eliminates the use of an endoscopic sheath, thus providing more maneuverability to the neurosurgeon. The brilliant illumination provided by the endoscope and the possibility of using electrocautery in the depths of the brain combined with the increased maneuverability make this technique valuable. Near-complete hematoma evacuation was achieved in 11 (85%) of 13 patients. There were four deaths (30%).

Conclusions

Safe and effective evacuation of large ICHs is possible by using the three-in-one endoscopic device. Appropriate indications for surgery in patients with large intracerebral hemorrhage must be developed.
