目的:观察复发性翼状胬肉逆行切除包埋加自体角膜缘干细胞移植手术的疗效。方法:选取56 例56眼复发性翼状胬肉行逆行手术剥离,将胬肉头端包埋于下方结膜下,联合自体角膜缘干细胞移植于角巩膜创面治疗复发性翼状胬肉。结果:术后随访8～24mo,53例角膜创面光滑,无血管及纤维组织重新侵入角膜。3例复发。结论:翼状胬肉逆行切除包埋加自体角膜缘干细胞移植手术对于复发性翼状胬肉治疗效果明确,能有效预防再次复发,其操作简便,患者术后不适症状减轻,值得推广应用。

Efficacy of retrograde excision and embedding plus limbal stem cell autograft for recurrent pterygium

AIM:To investigate the efficacy ofretrograde excision and embedding plus limbal stem cell autograft for recurrent pterygium.METHODS:Fifty-six cases (56 eyes) with recurrent pterygium received retrograde excision surgery with the head of pterygium embedded in the inferior conjunctiva. Then, the limbal stem cell autograft was transplanted to the corneoscleral wound.RESULTS:The corneal wound of 53 cases was smooth without any infiltration of fibrovascular tissues during the follow-up period for 8-24 months postoperatively 3 cases recurred.CONCLUSION:The efficacy of retrograde excision and embedding pluslimbal stem cell autograft for recurrent pterygium is definite and this surgery can prevent the recurrence of pterygium effectively. As it is easy to operate and can alleviate the symptoms of postoperative discomfort, this surgery should be widely applied.
