BACKGROUND: Mesh plug tension-free hernioplasty is commonly used for inguinal hernia. In the operation, different mesh materials can be selected, among which the modified Kugel mesh is extensively applied. OBJECTIVE: To observe the biocompatibility of modified Kugel mesh in mesh plug tension-free hernioplasty for inguinal hernia. METHODS: Total y 79 cases of inguinal hernia were treated by mesh plug tension-free hernioplasty. The patients were randomly divided into observation group repaired with Bard mesh (modified Kuge) (n=38) and control group repaired with Prolene mesh (n=41). After 12-month fol ow-up, levels of interleukin 6, C-reactive protein and tumor necrosis factor α were detected and compared before and after treatment;adverse events, including wound infection or infection caused by the mesh in the two groups were recorded. RESULTS AND CONCLUSION: Levels of interleukin 6, C-reactive protein and tumor necrosis factor α in the two groups were significantly decreased after treatment than before treatment (P < 0.05). No wound infection or infection caused by the mesh appeared in both two groups. Although scrotum effusion occurred in two cases of each group, their outcomes al improved significantly after active puncture and suction treatment without other serious problems. No recurrence was found during the 12-month fol ow-up. These results show that the modified Kugel mesh has good biocompatibility in mesh plug tension-free hernioplasty for inguinal hernia.%背景：腹股沟疝的治疗过程中，疝环充填式无张力疝修补术是一种常用的治疗方法。术中可以选择不同的补片材料，其中 Modified kugel 补片的应用十分广泛。目的：观察疝环充填式无张力疝修补术治疗腹股沟疝中 Modified kugel 补片的生物相容性。方法：纳入腹股沟疝患者79例，均实施疝环充填式无张力疝修补治疗。将入组患者随机分为观察组38例和对照组41例，分别使用巴德材料和普理灵疝装置补片。术后随访12个月，检测两组患者治疗前后的白细胞介素6、C-反应蛋白和肿瘤坏死因子α水平，进行比较，并记录两组不良事件发生，包括包括伤口感染或者补片材料所导致的感染等。结果与结论：①炎性因子水平：治疗前后，分别对两组进行炎性因子水平检测，与治疗前比较，两组患者的白细胞介素6、C-反应蛋白和肿瘤坏死因子α水平均显著下降(P <0.05)。②不良事件：两组患者均未出现伤口感染或者补片材料所导致的感染。术后两组各有2例患者出现阴囊积液现象，予以积极的穿刺抽吸治疗之后均显著好转，未出现其他严重问题。术后随访12个月，均未出现复发病例。③结果表明：疝环充填式无张力疝修补术治疗腹股沟疝中 Modified kugel 补片具有良好的生物相容性。
