应用中低温保存羊膜治疗翼状胬肉的临床观察

目的观察中低温保存羊膜治疗翼状胬肉的临床疗效。方法选择翼状胬肉患者共202例(218眼),随机将患者分为3组。A组:羊膜移植76例(85眼);B组:自体球结膜移植69例(72眼);C组:单纯胬肉切除57例(61眼)。观察术后各组胬肉的复发率。结果随访3月～20个月,A组复发6眼(占7.06%);B组复发7眼(占9.72%);C组复发15眼(占31.15%)组间经统计学处理A组与B组>0.05差异无统计意义;A组与C组<0.001差异有非常显著的统计学意义。结论单纯翼状胬肉切除,复发率高;羊膜移植与自体球结膜移植,两种手术方法术后复发率明显减少。中低温保存羊膜移植术后不产生排斥反应,羊膜保存方法简单易行,价格低廉,可随用随取,十分方便,是治疗翼状胬肉首选方法。

Clinical study of the transplantation of amniotic preserved at midrange hypothermy in the treatment of pterygium

Objective To observate the clinical efficacy of preserved amniotic in the treatment of ptergium. Methods Three groups of 202 pterygium patients (218 eyes) were studied: 76 patients (85eyes) with amniotic transplantation (group A); 69 patients (72eyes) with conjunctiva autografting (group B); 57 patients (61 eyes) with simple ptergium excision (group C).We studied the recurrence rate ot the three groups after operation. Results Patient were followed up 3 months to 20 months.The recurrence of the three group(A,B,C):6 eyes(7.06%);7 eyes(9.72%);15 eyes(31.15%) .There was no significant difference in recurrence between group A and group B ( >0.05),and there was significant difference in recurrence between group A and group C ( >0.05). Conclusion The recurrence rate of group C was obviously higher than the other groups. There was no rejection after the operation of amniotic transplantation.The construction of amniotic was easily to do and cheap;It was very easily to use the amniotic. Amniotic transplantation was the first method to treat the pterygium.
