角膜缘干细胞移植治疗翼状胬肉的远期疗效观察

Long-term efficacy observation on different surgical methods of limbal stem cell transplantation for pterygium

目的:探讨角膜缘干细胞移植治疗复发性翼状胬肉的远期疗效。方法:复发性翼状胬肉110例患者中,有19例(A组)接受翼状胬肉切除+丝裂霉素手术,91例(B组)接受了翼状胬肉切除+角膜缘干细胞移植术。结果:实施翼状胬肉切除术+丝裂霉素的19例患者中,术后6例翼状胬肉复发;接受翼状胬肉切除+角膜缘干细胞移植的91例患者中,术后有2例翼状胬肉复发。结论:经观察复发性翼状胬肉远期疗效证实,翼状胬肉切除+角膜缘干细胞移植术是治疗复发性翼状胬肉的理想方法。年轻患者较年老患者手术复发率高。

AIM：To discuss long-term effect of limbal stem cell transplantation for treatment of recurrent pterygium·METHODS：Among 110 patients with recurrent pterygium,19 patients underwent pterygium excision with mitomycin C,91 patients underwent pterygium excision with limbal stem cell transplantation·RESULTS：In 19 patients with implementation of pterygium excision with mitomycin C,6 patients had pterygium recurrence after surgery;In 91 patients who received pterygium excision with limbal stem cell transplantation,2 patients had pterygium recurrence after Surgery·CONCLUSION：The observation on the long-term curative effect of recurrent pterygium confirms that pterygium excision with limbal stem cell transplantation is an ideal way for the treatment of recurrent pterygium.surgical recurrence rate is higher in younger patients than that in older patients.
