翼状胬肉切除术移植结膜或羊膜的复发率比较

The comparison of the recurrence rates after pterygium excision combined with conjunctiva and with amnion transplantation

目的比较翼状胬肉切除联合自体结膜移植术与联合羊膜移植术后的复发率。方法翼状胬肉手术108例（130眼）随机分为A、B两组。A组为自体结膜移植术组（58例，70眼）。B组为羊膜移植术组（50例，60眼）。术后随访1年，以泪膜破裂时间及复发率作为分析统计指标。结果通过术后1年的跟踪随访，翼状胬肉切除联合自体结膜移植术组有8眼（11．42％）复发。联合羊膜移植术组有14眼（23．33％）复发。两组复发率比较，差异有统计学意义（P〈0．05）。两组泪膜破裂时间之间的差异无统计学意义（P〉0．05）。结论翼状胬肉切除联合自体结膜移植术治疗翼状胬肉能更有效的降低术后复发率。

Objective To compare the recurrence rates after pterygium excision combined with autologous conjunctiva and amniotic membrane transplantation. Methods One hundred and thirty eyes of one hundred and eight patients who underwent pterygium surgery were randomly divided into group A and group B. Patients in group A received pterygium excision combined with autologous conjunctiva transplantation, ineluding 70 eyes of 58 patients; and patients in group B received pterygium excision combined with amniotic membrane transplantation, including 60 eyes of 50 patients. All patients were followed up for 1 year. The tear film stability （breaking up time） and recurrence rates were recorded and analyzed. Results One year after the surgery, 8 eyes （ 1 l. 42% ） in group A had recurrent pterygium, and 14 eyes （23.33%） in group B had recurrent pterygium. The difference in recurrence rate between the two groups was statistically significant （ P 〈 0.05 ）. No statistically significant difference was observed between the two groups in postoperative tear film breaking up time （ P 〉 0.05 ）. Conclusion Pteryginm excision combined with autologous conjunctiva transplantation can make lower recurrence rate than pterygium excision with amniotic membrane transplantation.
