目的研究泪道造影对二次或多次泪道探通的术前指导作用。方法对250例需行泪道探通手术的儿童先行泪道造影检查,根据造影结果中阻塞部位不同(下、中、上段)将其分为3组(A、B、C组),并比较各组间造影结果与手术的吻合率及术后恢复情况。结果泪道造影与手术的吻合率3组间不存在差异性(P>0.05),术后恢复情况A、B组与C组存在明显差异性(P<0.05)。结论造影结果与患儿手术情况基本一致,对手术起明显指导作用;但高位阻塞的愈后与中低位阻塞者较大差异,故造影可以提示手术愈后。泪道造影在难治性及复杂性泪道阻塞手术中起重要作用。
Objective To study the preoperative guidance of lacrimal duct imaging on the exploration of secondary or multiple lacrimal passages. Methods 250 children undergoing lacrimal exploration were enrolled in this study. The lacrimal duct radiographs were divided into three groups (groups A, B, C) according to different obstructive sites (lower, middle and upper). The results of the contrast between the two groups were consistent with the operation and postoperative recovery. Results There was no significant difference between the three groups in lacrimal duct angiography and operation (P> 0.05). There was significant difference between group A and B and group C after operation (P <0.05). Conclusions The results of angiography are basically consistent with the operation of children and play a significant guiding role in the operation. However, the higher the postoperative obstruction and the lower and middle occlusion are, the larger the difference may be. Lacrimal ductography plays an important role in refractory and complicated lacrimal duct obstruction surgery.
