Abstract

This article describes a transconjunctival technique for pars plana vitrectomy using 20-gauge instruments. Sclerotomies are performed directly through the conjunctiva, Tenon's capsule, and sclera with a 19-gauge microvitreoretinal blade. A sutureless 20-gauge infusion cannula is then inserted and pars plana vitrectomy is performed in a standardized fashion using 20-gauge instruments. Each sclerotomy and its corresponding conjunctival incision is closed with a single stitch using a 7-0 polyglactin suture. This transconjunctival technique is a reasonable alternative surgical approach to minimize surgical trauma of tissues (eg, conjunctiva) and hasten postoperative recovery without the additional risks and costs associated with 25-gauge pars plana vitrectomy.

摘要

本文介绍了一种使用20号器械经结膜行扁平部玻璃体切除术的技术。用19号微型玻璃体视网膜刀直接经结膜、Tenon囊和巩膜制作巩膜切口。然后插入一个无缝合20号灌注套管，并使用20号器械以标准化方式进行扁平部玻璃体切除术。每个巩膜切口及其相应的结膜切口用7-0聚乙醇酸缝线单针缝合。这种经结膜技术是一种合理的替代手术方法，可将组织（如结膜）的手术创伤降至最低，并加速术后恢复，而不会带来与25号扁平部玻璃体切除术相关的额外风险和成本。
