目的：探讨Worst泪道探针联合改良泪道穿线插管法在复杂性泪小管断裂吻合术中的应用价值。

方法：回顾性研究。选取2019-03-01/2021-03-31遵义医科大学第二附属医院眼科收治的复杂性外伤性泪小管断裂患者68例68眼。根据手术方式分为两组，A组患者36例36眼采用Worst泪道探针寻找泪小管断端并联合改良泪道穿线插管法治疗，B组患者32例32眼采用显微镜下寻找泪小管断端，双路插管法吻合泪小管术治疗。比较两组患者临床疗效、术中寻找泪小管断端成功率、寻找泪小管断端时间、手术时间、疼痛程度、术后眼部异物感及并发症情况。

结果：A组患者临床疗效总有效率高于B组(94% vs 38%)，术中寻找泪小管断端成功率高于B组(100% vs 47%)，寻找泪小管断端时间、手术时间均短于B组，疼痛程度评分低于B组(均P<0.05)。术后随访6mo～1a，A组患者术后眼部异物感评分、泪小点撕裂及形态变化发生率、溢泪程度均低于B组(均P<0.05)。

结论：Worst泪道探针联合改良泪道穿线插管法治疗复杂性外伤性泪小管断裂能更精确找到泪小管断端，缩短手术时间，减轻患者疼痛及术后眼部异物感，提高临床疗效，降低并发症发生率。

METHODS: Retrospective study. A total of 68 cases(68 eyes)with complex traumatic canalicular laceration treated in the ophthalmology department of the Second Affiliated Hospital of Zunyi Medical University from March 1, 2019 to March 31, 2021 were selected. They were divided into two groups according to the surgical methods, with 36 patients(36 eyes)who were treated with the Worst lacrimal probe to find the broken end of lacrimal duct combined with improved lacrimal duct threading intubation in group A, and 32 patients(32 eyes)who were treated with microscope to find the broken end of lacrimal duct and two-way intubation anastomosis canaliculus intubation in group B. The clinical efficacy, success rate of intraoperative search for the broken end of lacrimal duct, searching time, operation time, the degree of pain, postoperative ocular foreign body sensation and complications were compared between the two groups.

RESULTS: The total effective rate of clinical efficacy in patients of group A was higher than that in group B(94% vs. 38%), the success rate of intraoperative search for broken end of lacrimal duct was higher than that in group B(100% vs. 47%), the searching time and operation time were shorter than those in group B, and the score of pain degree was lower than that in group B(all P<0.05). The postoperative follow-up for 6mo-1a showed that the ocular foreign body sensation score, the incidence of lacrimal punctum rupture and morphological change, and the degree of tear overflow in group A were all lower than those in group B(all P<0.05).

CONCLUSION: Worst lacrimal probe combined with modified lacrimal duct intubation for the treatment of complex traumatic canalicular laceration can find the broken end of lacrimal duct more accurately, shorten the operation time, reduce the pain and foreign body sensation of patients, improve clinical efficacy and reduce the incidence of complications.
