Endoscopic Approach for Colloid Cyst Resection

This research aims to optimize the minimally invasive endoscopic resection of third ventricular colloid cysts. It evaluates surgical efficacy, safety, patient selection, and intraoperative navigation to reduce complications and improve patient outcomes. Intraoperative ultrasound, neuronavigation, high-definition endoscopes, and advanced bipolar coagulation techniques are used to enhance the precision and safety of endoscopic colloid cyst resection.

Endoscopic removal of colloid cysts is a safe and effective alternative to microsurgical techniques, offering shorter operation times, lower morbidity, and faster patient recovery. To begin, insert the endoscope into the sheath to access the cyst. Inside the lateral ventricle.

Identify key structures such as the lateral ventricular cavity, foramen of Monro, choroid plexus, thalamostriate vein, and septal vein. Locate the colloid cyst and approach it through the foramen of Monro under direct visualization. Carefully separate the cyst wall from the surrounding tissue using a dissector.

After dissecting cyst contents, coagulate components of the cyst. Grasp the cyst wall firmly with small forceps and perform rotational movements. Then control bleeding via coagulation and irrigation.

Finally, remove the endoscopic system after achieving hemostasis. Preoperative MRI Images showed the presence of a colloid cyst with clear visualization of its relationship to adjacent structures. Postoperative MRI Images confirmed the complete resection of the colloid cyst with no signs of recurrence.
