高频超声引导下小切口入路治疗腕管综合征的疗效

Observation on the preliminary efficacy of high frequency ultrasound-guided small incision in treating carpal tunnel syndrome

目的探讨高频超声在小切口入路治疗腕管综合征(CTS)中的临床应用价值。方法将2009年1月~2014年12月收治的66例经保守治疗无效需行小切口入路手术的CTS患者分为实验组和观察组,各33例。实验组患者术前行高频超声检查腕管受损情况,对照组术前未行高频超声检查。比较两组患者的治疗有效率、手术时间、术中出血量、平均住院时间、术后瘢痕长度、术后疼痛发生率及术后并发症发生率。结果术后随访12月,实验组与对照组术中出血量(16.39±4.44mLvs18.97±5.05mL)、手术时间(12.55±1.75minvs13.48±2.02min)、术后总并发症发生率(9.1%vs33.3%)的差异均有统计学意义(P<0.05);实验组平均住院时间、术后疤痕长度、术后疼痛发生率及治疗有效率与对照组比较差异均无统计学意义(P>0.05)。结论高频超声引导下小切口入路行腕管切开松解减压术是治疗CTS的一种安全、可靠的治疗方法,有利于患者术后早日恢复健康。

Objective To investigate the clinical application value of high frequency ultrasound examination in carpal tunnel syndrome with a small incision. Methods A total of 66 patients diagnosed with CTS who failed in conservative treatment and required minimal-access carpal tunnel release technique were divided into ultrasound group and control group, with 33 cases in each. The effective rate, operative time, blood loss volume, average hospital day, scar length, incidence of postoperative pain and complications were compared between the two groups. Results All patients were followed up for 12 months, the efficacy of blood loss volume(16.39±4.44 mL vs 18.97±5.05 mL, P<0.05), operative time(12.55±1.75 min vs 13.48±2.02 min, P<0.05), incidence of postoperative complications(9.1% vs 33.3%, P<0.05) were improved significantly in ultrasound group. There was no significant difference between the two groups in average hospital day, scar length and incidence of postoperative pain and complications (P>0.05). Conclusion Minimal-access carpal tunnel release technique assisted with high frequency ultrasound is a safe and reliable method for carpal tunnel syndrome. It is beneficial for patients to recover from operation.
