To describe a new 20-gauge transconjunctival vitrectomy procedure that we designed, to evaluate its usefulness, and to compare two different methods of use.
The records of 431 patients (433 eyes) who underwent 20-gauge transconjunctival vitrectomy at the Surugadai Hospital of Nihon University between March 2003 and January 2004 were studied retrospectively. In surgical method 1, 20-gauge wounds were made through the conjunctiva and sclera together. In surgical method 2, 20-gauge conjunctival openings were made 2 mm posterior to the sclerotomies. Absorbable sutures were used to stitch the scleral and conjunctival openings simultaneously in both methods.
A 20-gauge transconjunctival vitrectomy has various benefits and is indicated for nearly all ocular diseases. Moreover, it is not limited by the intraocular instruments required. However, since cannulas were not placed in all ports, conjunctival edema occurred more easily with surgical method 2 owing to the leakage of perfusion fluid.

描述我们设计的一种新型20G经结膜玻璃体切除术，评估其效用，并比较两种不同的使用方法。
回顾性研究2003年3月至2004年1月在日本大学巢鸭医院接受20G经结膜玻璃体切除术的431例患者（433只眼）的记录。手术方法1中，20G切口通过结膜和巩膜一起制作。手术方法2中，结膜开口在巩膜切开处后方2mm处制作。两种方法均使用可吸收缝线同时缝合巩膜和结膜开口。
20G经结膜玻璃体切除术有多种益处，几乎适用于所有眼部疾病。此外，它不受所需眼内器械的限制。然而，由于并非所有端口都放置了套管，手术方法2因灌注液渗漏更容易发生结膜水肿。
