Sutureless Transconjunctival 20 Gauge Vitrectomy (20G STV) is a technique that reduces the operating time and the post-operative inflammation.
Eighty-four eyes underwent this new technique. Conjunctival diathermy over the ports before sclerostomy produced adhesions adequate to stop transoperative conjunctival chemosis. The MVR blade introduced into the conjunctiva-sclera in a bevelled direction. The tunnel incision that was created left without a suture at the end of the operation.
Three patients (3,5%) had hypotony (2-6 mmHg) on day 1 that was normalized 3 days later. Two of them had a bleb formation and the rest a very minor leakage through a flat conjunctiva. No other serious complications occurred as a result of this novel transconjunctival approach. Also there were no differences in visual acuity, intraocular pressure, redetachments, or inflammations between the patients who underwent this technique and the patients having the conventional 20-gauge pars plana technique.
20G STV is a safe and practical technique for the full spectrum of vitreoretinal surgery. It makes the surgery quicker and is well tolerated by patients.
无缝合经结膜20G玻璃体切除术(20G STV)是一种可缩短手术时间并减轻术后炎症的技术。
84只眼接受了这项新技术。在巩膜造口术前对端口进行结膜透热疗法,产生足够的粘连以阻止术中结膜水肿。将MVR刀片以倾斜方向插入结膜-巩膜。所形成的隧道切口在手术结束时不进行缝合。
3例患者(3.5%)在第1天出现低眼压(2 - 6 mmHg),3天后恢复正常。其中2例出现水泡形成,其余通过扁平结膜有非常轻微的渗漏。这种新型经结膜方法未导致其他严重并发症。接受该技术的患者与采用传统20G平坦部技术的患者在视力、眼压、视网膜再脱离或炎症方面也无差异。
20G STV对于全范围的玻璃体视网膜手术是一种安全且实用的技术。它使手术更快,并且患者耐受性良好。
