The pigtail probe method of repairing canalicular lacerations is a widely used technique, however its long-range effectiveness has never been documented. By evaluating statistical data on 51 canalicular lacerations, and then examining 30 patients who had been repaired by the pigtail probe we were able to conclude that: a left inferior canalicular laceration, in a young male, following assault is the most common presentation; that this method objectively yields a 36.6% patency rate with a 10% incidence of iatrogenic damage to the uninvolved side; that 73.3% of the failures remained asymptomatic; secondary to keratitis sicca, a functioning conjunctival canalicular fistula, or the patent remaining canaliculus; and that the inferior canaliculus appears to be symptomatically more important than the superior canaliculus. It is suggested that all canalicular lacerations be repaired, but that the pigtail probe method be abandoned.
猪尾探针法修复泪小管裂伤是一种广泛应用的技术，然而其长期有效性从未得到证实。通过评估51例泪小管裂伤的统计数据，然后检查30例接受猪尾探针修复的患者，我们能够得出以下结论：年轻男性在遭受攻击后出现的左下泪小管裂伤是最常见的表现；该方法客观上产生36.6%的通畅率，对未受累侧造成医源性损伤的发生率为10%；73.3%的失败病例无症状，继发于干燥性角膜炎、功能性结膜泪小管瘘或残留通畅的泪小管；并且下泪小管在症状上似乎比上泪小管更重要。建议修复所有泪小管裂伤，但应放弃猪尾探针法。
