[摘要]目的:探讨初发翼状胬肉术后复发的影响因素。方法:对初发翼状胬肉行胬肉切除加结膜瓣转移术,按术后结膜瓣缝合平整程度分为3组,平整组共计36例,39眼;欠平整组共计41例,48眼;不平整组共计19例,22眼。观察各组手术1个月后的睑裂部充血率及结膜瓣平整程度与复发的关系。结果:平整组手术1个月后的睑裂部充血率为7.2%,欠平整组为18.1%,不平整组为30.8%。入选96例109眼的复发率为13.8%,3组的复发率依次为5.1%、12.5%、31.8%。平整组与不平整组复发率差异有统计学意义(P<0.05)。结论:结膜瓣缝合平整可缩短术后愈合时间,减少睑裂部结膜充血及结膜下新生血管形成,是减少术后复发的重要因素。

[Abstract]Objective: To investigate the factors lead to recurrence after surgical treatment on primary pterygium. Methods: After performing excision and self-conjunctiva flap transplantation on primary pterygium, we divided patients into 3 groups according to suture quality.There were 39 eyes of 36 patients in good suture quality group, 48 eyes of 41 patients in general suture quality group, and 22 eyes of 19 patients in low suture quality group. To investigate the hyperemia rate in palpebral fissure one month after operation in each group and the relationship between the suture qualities of conjunctiva flap and recurrence. Results: The hyperemia rate in palpebral fissure one month after operation in good suture quality group was 7.2%, general suture quality group was 18.1%, low suture quality group was 30.8%. The recurrence rates were 5.1%,12.5%,31.8% respectively in each group.Difference between low suture quality group and good suture quality group was significant.(P<0.05).Conclusion: Good suture quality, reducing healing time after operation, reducing the possibility of conjunctiva hyperemia in palpebral fissure, decreasing the neovascularization under conjunctiva, is an important factor that leads to less recurrence.

胬肉切除加结膜瓣转移术能降低翼状胬肉术后的复发率[1],已被较多学者采用。我们在实施该手术治疗初发翼状胬肉时发现,转移结膜瓣的平整程度与复发关系密切,遂对近年来的手术效果作一回顾性分析。
1 资料与方法
1.1一般资料
近5年来我院行胬肉切除加结膜瓣转移手术共计112例128眼,其中复发翼状胬肉13例14眼,术后半年~1年未能成功随访者5例5眼。初发翼状胬肉患者排除眼部疾患(如急性结膜炎、疱性结膜炎、沙眼、青光眼、葡萄膜炎、巩膜炎、泪囊炎和干眼等),胬肉轻度充血或不充血(如充血较重,手术前用典必殊点眼3~7 d),胬肉头部超过角巩膜缘1.5 mm,术后半年~1年能主动复诊或成功电话随访者入选。入选者96例109眼,其中男55例59眼,女41例50眼,平均年龄45.3岁。
1.2方法
1.2.1手术方法及术后处理采用胬肉切除加结膜瓣转移法。术中尽可能切除干净角膜表面及巩膜表面的胬肉组织[2],采用“鹰嘴”烧灼止血时,用湿棉签垫隔,避免过度烧灼。结膜瓣取胬肉上方的健康球结膜,采用旋转移植的方法,5-0丝线或7-0尼龙线间断缝合。术后口服抗生素5 d,术眼点典必殊眼药水及眼膏,7 d拆线,拆线后典必殊眼药水及眼膏点眼,控制到睑裂部无明显充血后逐渐减量至停用。术后2周复查,眼压升高至21 mmHg以上,或术后1个月睑裂部仍充血者亦开始减量至停用。
1.2.2分组方法考虑到术中可能存在不牢靠的缝合,手术当天术眼疼痛,眼球转动可导致结膜撕裂等,我们按术后第1天睑裂部结膜平整程度将所有病例分为平整组、欠平整组、不平整组3组。平整者缝线松紧适度,对合好(结膜瓣蒂部可有少许结膜皱褶不认为是对合缺陷[3]);欠平整者存在1处(两线结之间)明显的对合缺陷,如张力过大伤口裂开明显,缝合一侧结膜堆积;不平整者存在两处或两处以上明显的对合缺陷,或有结膜明显撕裂,有舌状结膜瓣残留。入选者中平整组共计36例,39眼;欠平整组共计41例,48眼;不平整组共计19例,22眼。
1.2.3复诊及复发的判断手术后3个月时复诊1次,由患者回忆睑裂部球结膜充血的天数,未能复诊者12例(14眼),予电话随访。以手术后1月为观察起点,睑裂部充血的天数除以总的观察天数(多数患者均不是刚好3个月时复诊)即为充血率。手术后半年~1年复诊时观察睑裂部结膜下组织增生情况,裂隙灯检查发现结膜下血管超过角巩膜缘1 mm,即判断为复发。拒绝复诊的患者45例48眼,电话随访,43例(46眼)患者自我判断或由外院判断无复发,2例患者由外院判断复发。
