摘要:

背景:脱细胞异体真皮被自体组织取代后即不被机体视为异物,可减少局部炎症细胞浸润,减轻炎症反应,能够达到重建腱鞘后在体内永久存留的可能性。
目的:探寻脱细胞异体真皮重建腱鞘结合玻璃酸钠预防肌腱粘连松解后再粘连的效果。
方法:将腕部肌腱损伤修复后粘连需要再次手术行肌腱松解的56例患者随机分为试验组(n=26)与对照组(n=30)。试验组肌腱粘连行肌腱松解后,以脱细胞异体真皮缝合成直径大于肌腱的套管状套于肌腱粘连处,使套管达到远近端未粘连部分各1 cm,缝合固定重建腱鞘两端于周围组织,套管内注射玻璃酸钠,缝合伤口;对照组肌腱松解后直接缝合伤口。术后随访半年,对比两组肌腱松解情况及再次粘连发生情况。
结果与结论:试验组26例患者51根肌腱,有效49根,无效2根,有效率为96%;对照组30例患者58根肌腱,有效46根,无效12根,有效率为79%,两组有效率比较差异有显著性意义(P < 0.05)。表明以脱细胞异体真皮重建腱鞘结合玻璃酸钠预防肌腱粘连松解后再粘连效果明显。

Abstract:

BACKGROUND: Acellular allogeneic dermis that is replaced by autologous tissue is not considered as foreign body, and can reduce local inflammation and cell infiltration, to achieve the possibility of permanent retention in the body after reconstruction of the tendon sheath.
OBJECTIVE: To evaluate the efficacy of acellular dermal matrix combined with sodium hyaluronate to prevent adhesiolysis after adhesions of tendon during the procedure of tendon sheath reconstruction.
METHODS: A total of 56 patients who required secondary adhesiolysis to repair tendon adhesions after repair of wrist tendon injury were randomly separated into experimental group (26 cases) and control group (30 cases). Experimental group: after tendon release, the sleeve-shaped acellular dermal matrix with a large diameter than the tendon was sewn into the site of tendon adhesions, 1 cm distant to the distal and proximal ends of non-adhesion tendon, to reconstruct the tendon sheath that was fixed at the both ends of surrounding tissue. Then, the incision was sutured after injection of sodium hyaluronate via the sleeve. Control group: after tendon release, the wound was sutured directly. All of the patients were followed-up for 6 months, to compare the efficacy of tendon release and reoccurrence of adhesions.
RESULTS AND CONCLUSION: For 51 tendons from 26 patients in the experimental group, valid treatment was in 49 tendons and invalid in 2 tendons, with the effective rate of 96%; for 58 tendons from 30 patients in the control group, effective treatment was in 46 tendons, and invalid in 12 tendons, with the effective rate of 79%. There was a significant difference in the effective rate between the two groups (P < 0.05). The reconstruction of tendon sheath using acellular dermal matrix combined with sodium hyaluronate can effectively improve adhesions after adhesiolysis.
