Endoscopic dacryocystorhinostomy (DCR) is a widely performed and safe procedure for the treatment of nasolacrimal duct obstruction manifested as epiphora or dacryocystitis. Current success rates are above 90%. Data on causes for failure of the procedure are sparse. We investigated the influence of several preoperative parameters on surgery outcome and to establish that parameters are linked with failure.
A retrospective analysis of the medical records of all consecutive patients who underwent endoscopic DCR in the Tel-Aviv Medical Center, a tertiary referral center, between January 2010 and August 2016 were retrospectively examined and data on the occurrence of surgical failure and reasons for failure were retrieved.
A total of 165 patients (183 eyes) were included. The overall success rate for the surgery was 94.7%. The parameters that correlated significantly with failure were coexisting diabetes mellitus (P = 0.037), allergy to medications (P = 0.034), and prior ocular surgery (P = 0.043). There was no correlation between the surgical failure rates and facial trauma, previous nasal or lacrimal surgery, or the usage of a stent.
Endoscopic DCR is a safe and effective surgical procedure. Diabetes mellitus, allergies, and previous ocular surgery may lead to surgical failure. Patients with these risk factors should be aware of increased failure rates.
经鼻内镜下鼻腔泪囊吻合术（DCR）是治疗表现为溢泪或泪囊炎的鼻泪管阻塞的常用且安全的方法。目前，该手术的成功率超过 90%。关于手术失败原因的数据较为缺乏。我们旨在调查几个术前参数对手术结果的影响，并确定这些参数与手术失败相关。
对 2010 年 1 月至 2016 年 8 月在特拉维夫医疗中心接受经鼻内镜 DCR 的所有连续患者的病历进行回顾性分析，并检索手术失败的发生和失败原因的数据。
共纳入 165 例（183 只眼）患者。该手术的总体成功率为 94.7%。与失败显著相关的参数是并存的糖尿病（P=0.037）、对药物过敏（P=0.034）和先前的眼部手术（P=0.043）。面部创伤、先前的鼻或泪囊手术或支架的使用与手术失败率之间没有相关性。
经鼻内镜下 DCR 是一种安全有效的手术方法。糖尿病、过敏和先前的眼部手术可能导致手术失败。具有这些风险因素的患者应意识到手术失败率增加。
