两种不同术式治疗翼状胬肉的疗效比较

目的:比较带干细胞的自体结膜转位术与带干细胞的自体结膜移植术治疗翼状胬肉的临床效果。方法:患者50例(60眼)分为2组,A组采用胬肉切除联合带干细胞的自体结膜转位术,B组采用胬肉切除联合带干细胞的自体结膜移植术。每组的手术时间及术后效果进行比较。结果:结膜及角膜的上皮化均在术后2～5d内完成,随访6～12mo,每组均有1例复发,复发率无组间差异。A组手术时间25±8min,B组43±11min,组间差异显著(P<0.05t-test)。结论:两种手术方法均可以有效治疗及防止胬肉复发,比较而言,带干细胞的自体结膜转位术更简单、易于操作,患者亦愿意接受。

Comparison of effects of different pterygium surgeries

AIM: To compare the clinical outcomes of pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells to treat and prevent the recurrence of pterygium.METHODS: Fifty patients (60 eyes) were divided into 2groups, and pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells (group A) and pterygium excision followed by transplantation of conjunctiva autograft harvested from counter-side limbus with stem cells (group B) were performed respectively.The surgical time of each case was recorded.RESULTS: All the 50 cases (60 eyes) of pterygium were recruited. The epithelization of cornea and conjunctiva in all cases finished in 2-5d, During the follow-up of 6-12mo, pterygium reoccurred in 2 cases (1 in each group), with no difference in recurrence rate. The mean surgical time was 25± 8min for group A,43± 11min for group B, the difference being statistically significant (P＜0.05, t-test).CONCLUSION: Both methods, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells are effective on treating and reducing the recurrence of pterygium. Compared with the latter, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells is simpler and easier to perform, and is preferred by the patients too.
