【摘要】 目的 探討四種不同手術方式治療翼狀胬肉的療效。方法 169例(212眼)翼狀胬肉患者, 根據手術方式不同分為Ⅰ組(單純手術切除術, 23眼)、Ⅱ組(手術切除聯合自體結膜移植術, 72眼)、Ⅲ組(手術切除聯合自體角膜緣干細胞移植術, 81眼)、Ⅳ組[絲裂霉素(MMC)注射后聯合手術切除術, 36眼]。比較四組患眼復發情況及不同胬肉分級患眼復發情況。結果 Ⅰ組復發率為39.13%, Ⅱ組復發率為11.11%, Ⅲ組復發率為4.94%, Ⅳ組復發率為13.89%。Ⅰ組復發率高于Ⅱ、Ⅲ、Ⅳ組, 差異均具有統計學意義(χ2=9.314、19.148、4.941, P<0.05)。Ⅱ、Ⅲ、Ⅳ組組間兩兩比較, 差異均無統計學意義(P>0.05)。Ⅰ°胬肉復發率為2.33%, Ⅱ°胬肉復發率為13.46%, Ⅲ°胬肉復發率為16.92%。Ⅰ°胬肉復發率低于Ⅱ°、Ⅲ°, 差異均具有統計學意義(χ2=4.117、5.584, P<0.05)。Ⅱ°、Ⅲ°胬肉比較, 差異無統計學意義(P>0.05)。結論 自體結膜移植術、自體角膜緣干細胞移植術及MMC注射后聯合手術切除術均可以減少翼狀胬肉術后復發。

【Abstract】 Objective To discuss the efficacy of four different surgical methods for the treatment of pterygium. Methods A total of 169 cases (212 eyes) pterygium patients were divided by different surgical methods into group Ⅰ (simple surgical excision, 23 eyes), group Ⅱ (surgical excision combined with autologous conjunctival transplantation, 72 eyes), group Ⅲ (surgical excision combined with autologous limbal stem cell transplantation, 81 eyes) and group Ⅳ [surgical resection after injection of mitomycin (MMC), 36 eyes]. Comparison were made on recurrence of involved eyes in four groups and recurrence of involved eyes of different grades of pterygium. Results Group Ⅰ had recurrence rate as 39.13%, which was 11.11% in group Ⅱ, 4.94% in group Ⅲ and 13.89% in group Ⅳ. Group Ⅰ had higher recurrence rate than group Ⅱ, Ⅲ and Ⅳ, and their difference was statistically significant (χ2=9.314, 19.148, 4.941, P<0.05). Group Ⅱ, Ⅲ and Ⅳ had no statistically significant difference (P>0.05). The recurrence rate of Ⅰ° pterygium was 2.33%, which were 13.46% of Ⅱ°pterygium and 16.92% ofpterygium. The recurrence rate of Ⅰ° pterygium was lower than Ⅱ° and Ⅲ°pterygium, and the difference was statistically significant (χ2=4.117, 5.584, P<0.05). There was no statistically significant in Ⅱ° and Ⅲ°pterygium (P>0.05). Conclusion Autologous conjunctival transplantation, autologous limbal stem cell transplantation and combined operation after MMC injection can reduce the recurrence of pterygium.

翼狀胬肉(Pterygium)作為眼科的常見病、多發病, 其病理學改變主要表現為上皮下纖維血管組織增生和膠原纖維變性。其病因尚不十分明確, 但現大多認為與環境因素及過多接觸紫外線照射有關。目前臨床上主要的治療方法為手術治療, 其中主要手術方式有:單純手術切除術、手術切除聯合自體結膜移植術、手術切除聯合自體角膜緣干細胞移植術、MMC注射后聯合手術切除術。本研究選取在本院接受上述四種不同方式治療的翼狀胬肉患者, 分析其術后療效及復發情況, 現報告如下。
1 資料與方法
1. 1 一般資料 選取2015年1月~2018年1月在本院治療的翼狀胬肉患者169例(212眼), 年齡43~66歲, 平均年齡(59.38±19.32)歲;男81例(103眼), 女88例(109眼), 43例(男26例, 女17例)為雙眼發病, 其余為單眼發病, 均為鼻側發病, 全部患者身體健康狀況均為良好。參考胬肉分級將患眼分為Ⅰ°:即胬肉伸入角膜緣1~2 mm, 43眼;Ⅱ°:即胬肉伸入角膜緣3~4 mm, 104眼;Ⅲ°:即胬肉超過瞳孔緣, 65眼。根據患者接受的手術方式不同分成Ⅰ組(23眼)、Ⅱ組(72眼)、Ⅲ組(81眼)、Ⅳ組(36眼)。充分告知患者及家屬不同術式的治療方法及可能的復發情況, 獲得患者或家屬簽署知情同意書。
