Abstract：
Colloid cysts are nonneoplastic epithelial lesions arising from the roof of the third ventricle near the foramen of Monro. They comprise approximately 0.5% to 2% of all brain lesions.1-3 Surgical resection is the definitive treatment when indicated. The microsurgical approach is generally considered the \"gold standard,\" but the endoscopic approach has been gaining popularity.4-6 The choice is usually based on a surgeon\'s preference and key image findings such as the presence of hydrocephalus. The advantage of an endoscopic approach is shorter operative time, faster recovery, and a more anterolateral approach to avoid manipulation on the fornix. The major drawback of the endoscopic approach was previously reported as a higher recurrence rate due to incomplete removal of the cyst capsule. However, it has been shown that the rate of capsule excision may be similar to that of microsurgery, ranging from 80 to 100%.7-14 The authors demonstrate an endoscopic resection of a recurrent colloid cyst with bimanual technique through parallel channels in a ventriculoscope. Video 1 highlights the critical steps involved in preserving both vascular and neural structures during the procedure.
摘要：
胶体囊肿是起源于Monro孔附近第三脑室顶部的非肿瘤性上皮病变。它们约占所有脑损伤的0.5％至2％。1-3手术切除是明确的治疗。显微外科手术方法通常被认为是黄金标准，但内窥镜检查方法已越来越普及。4-6选择通常基于外科医生的偏好和关键图像发现，如脑积水的存在。内窥镜入路的优点是手术时间短，更快的恢复，以及更多的前外侧入路以避免对穹窿进行操纵。先前曾报道内窥镜入路的主要缺点是由于囊肿囊的去除不完全，复发率较高。然而,已经表明，胶囊切除的速度可能与显微外科手术相似，范围从80％到100％。7-14作者通过脑室镜中的平行通道，通过双向技术对复发性胶体囊肿进行了内窥镜切除。视频1强调了在手术过程中保护血管和神经结构的关键步骤。
