To determine the efficacy of dacryocystoplasty with balloon dilatation in the treatment of complete and partial obstruction of the lacrimal drainage system.
The procedure was performed on 26 patients with epiphora due to complete (n=16) or partial (n=10) obstruction of the lacrimal drainage system. A flexible tipped guide wire was introduced through the superior canaliculus into the inferior meatus and manipulated out of the nasal cavity. A 3 mm balloon was then introduced in a retrograde direction over the guide wire and dilated at the obstruction site.
The procedure was technically successful in all patients with partial obstruction, but unsuccessful in four of 16 cases with complete obstruction. Reobstruction occurred in eight of 12 patients with complete obstruction, and in five of 10 patients with partial obstruction. The overall success rate was 25% for complete and 50% for partial obstructions. The mean follow up was 14 months (8-37 months).
Although the balloon dacryocystoplasty is a simple and minimally invasive technique, the outcome from our study indicates that it is not advisable for treatment of complete obstruction of the lacrimal drainage system. Balloon dilatation may prove suitable for the treatment of patients with partial obstruction below the level of the lacrimal sac, especially in those who are poor candidates for surgery, or who do not wish to undertake dacryocystorhinostomy. Even in the partial obstruction group the success rate was only 50%, so that further modification to the technique and controlled studies are likely to be required before it could be recommended for general use.
确定球囊扩张泪囊成形术治疗泪道系统完全性和部分性阻塞的疗效。
对26例因泪道系统完全性阻塞(n = 16)或部分性阻塞(n = 10)而溢泪的患者实施该手术。通过上泪小管将可弯曲头端导丝插入下鼻道,并操作使其穿出鼻腔。然后沿导丝逆行插入一个3毫米的球囊,在阻塞部位进行扩张。
该手术在所有部分性阻塞患者中技术上均获成功,但在16例完全性阻塞患者中有4例失败。12例完全性阻塞患者中有8例复发阻塞,10例部分性阻塞患者中有5例复发阻塞。完全性阻塞的总体成功率为25%,部分性阻塞为50%。平均随访时间为14个月(8 - 37个月)。
尽管球囊泪囊成形术是一种简单且微创的技术,但我们的研究结果表明,它不适用于治疗泪道系统的完全性阻塞。球囊扩张可能适用于治疗泪囊水平以下的部分性阻塞患者,特别是那些手术条件较差或不愿接受泪囊鼻腔吻合术的患者。即使在部分性阻塞组中,成功率也仅为50%,因此在推荐该技术广泛应用之前,可能需要对其进行进一步改进并开展对照研究。
