The purpose is to compare the clinical results of using silk versus nylon sutures for conjunctival autograft suturing in pterygium surgery.
In this prospective, randomized, controlled, clinical trial 50 eyes from 50 patients with primary nasal pterygium were randomized to undergo pterygium surgery with the use of either nylon sutures or silk sutures for conjunctival autograft suturing. Patients were followed up for 6 months. Main outcome measures included recurrence, postoperative discomfort according to a visual analog scale (VAS), graft hyperemia, and graft edema.
According to the results, there was no significant difference between groups regarding recurrence rate of pterygium ( = 0.72). A significant decrease in the mean VAS discomfort score from day 1 to day 14 was observed in both groups ( = 0.001); postoperative discomfort during the first 2 weeks, was not significantly different between the two groups. At 2 weeks' postoperatively, significantly greater number of nylon sutures remained on the autograft ( = 0.021), some of which were buried and could not be removed.
Both silk and nylon are effective suture materials for autograft suturing in pterygium surgery with similar postoperative discomfort and recurrence rate. Significantly greater number of nylon sutures remains buried on the autograft and could not be removed easily.
比较在翼状胬肉手术中使用丝线与尼龙线进行结膜自体移植缝合的临床效果。
在这项前瞻性、随机、对照临床试验中，将50例原发性鼻侧翼状胬肉患者的50只眼随机分为两组，分别使用尼龙线或丝线进行结膜自体移植缝合，接受翼状胬肉手术。对患者进行6个月的随访。主要观察指标包括复发情况、根据视觉模拟量表（VAS）评估的术后不适、移植片充血和移植片水肿。
结果显示，两组在翼状胬肉复发率方面无显著差异（P = 0.72）。两组从第1天到第14天的平均VAS不适评分均显著降低（P = 0.001）；两组在前2周的术后不适无显著差异。术后2周时，尼龙线留在自体移植片上的数量显著更多（P = 0.021），其中一些已埋入无法拆除。
在翼状胬肉手术中，丝线和尼龙线都是有效的自体移植缝合材料，术后不适和复发率相似。尼龙线留在自体移植片上且埋入无法拆除的数量显著更多。
