文题释义:
无张力疝修补:是普外科最常用的手术方式之一,以补片修复的使用越来越广泛。补片分为轻量型补片、中量型补片和重量型补片,轻量型补片28 g/m2,中量型45 g/m2,重量型95 g/m2。补片是一种异物,置入人体后会发生急慢性炎症反应,慢性炎症反应主要是发生纤维化,纤维细胞增生,形成瘢痕围绕补片,这种反应可以一直存在。无张力疝修补后血肿和异物感的发生率比较高,补片降低腹壁的顺应性,引进腹壁有僵硬的感觉,少数会出现精索肉芽肿以及肠漏等并发症,降低异物感可以改善无张力疝修补的手术效果。腹股沟区能够承受的腹内压力比较低,腹股沟患者的腹股沟区能承受的腹内压力为小于10 kPa,腹壁的撕裂强度16 N/cm,补片的撕裂强度远远大于腹壁的撕裂强度。动物实验研究发现将普通灵平片的聚丙烯含量降低到25%,补片的强度仍然大于腹壁的撕裂强度,但这种轻量型补片置入体内后的炎症反应明显降低,置入部位的纤维化程度也降低,腹壁的顺应性明显优于重量型补片。

轻量型聚丙烯补片:为由多股聚丙烯加入可吸收聚糖乳糖纤维混合编织成的大孔径轻型补片(薇普Ⅱ网片,83 g/m2),聚糖乳糖成分在术后8 周左右能被组织吸收,聚丙烯含量仅为27-30 g/m2,具有超薄轻质、柔软、大网孔径的特点。

背景:轻量型聚丙烯补片在降低聚丙烯含量的同时加入一些可吸收成分,这些可吸收成分是否会对机体产生不良反应?
目的:比较轻量型和标准型聚丙烯补片修补腹股沟无张力疝的效果。
方法:将40例男性腹股沟疝患者分为2组,每组20例,试验组采用轻量型聚丙烯补片进行修补,对照组采用标准型聚丙烯补片进行修补。于修补后第2天检测血白细胞计数、中性粒细胞百分比和C-反应蛋白水平,于修补后2 d、1个月、3个月、6个月评估疼痛与不适感,同时记录并发症。
结果与结论:两组阴囊水肿、血清肿等并发症发生率比较差异无显著性意义。试验组修复后第2天的白细胞计数、中性粒细胞百分比低于对照组(P < 0.05),两组间C-反应蛋白水平比较差异无显著性意义。两组修补后不同时间点的疼痛情况无差异,试验组修补后不同时间点的不适感发生率低于对照组(P < 0.05)。结果表明,轻量型聚丙烯补片可降低无张力疝修补后的炎症发应和不适感发生率。

Abstract:

BACKGROUND: Lightweight polypropylene mesh with lower content of polypropylene is added with some absorbable ingredients, and will these ingredients cause adverse reactions in vivo?

 

OBJECTIVE: To compare the effect of lightweight polypropylene mesh and standard polypropylene mesh on tension-free repair of inguinal hernia.

 

METHODS: Forty patients with inguinal hernia were randomly divided into two groups (n=20 per group): the patients were treated by lightweight polypropylene mesh as experimental group and those treated by standard polypropylene mesh as control group. At 2 days after surgery, white blood cell counts, neutrophils percentage and level of C-reactive protein were detected. Furthermore, pain scores as well as discomfort incidence and complications were assessed and recorded at 2 days, 1, 3 and 6 months after surgery, respectively.

 

RESULTS AND CONCLUSION: There were no significant differences in postoperative complications between two groups. White blood cell counts and neutrophils percentage in the experimental group were significantly lower than those in the control group (P < 0.05), but the level of C-reactive protein had no significant difference. Besides, pain scores had no significant difference between the two groups, but the postoperative discomfort incidence in the experimental group was significantly decreased compared with the control group(P < 0.05). In conclusion, lightweight polypropylene mesh can reduce postoperative inflammation and discomfort incidence.
