METHODS: A total of 109 patients who underwent MVD were analyzed and divided into the transposition (86 patients) and interposition (23 patients) groups. Postoperative outcomes at 1 month and 1 year were assessed and compared, including rates of spasm relief, complications, and recurrence.
RESULTS: Outcome assessment revealed higher rates of early spasm relief in the interposition group (66.3% vs. 100%, transposition vs. interposition, respectively, p = 0.0004), although spasm relief at 1-year postoperatively was comparable between the two groups (84.9% vs. 95.7%, transposition vs. interposition, respectively, p = 0.2929). No significant differences were observed in complication and recurrence rates. Kaplan-Meier analysis demonstrated no significant differences in the duration of spasm resolution by MVD method (p = 0.4347, log-rank test).
CONCLUSIONS: This study shows that both the transposition (Surgicel® and fibrin glue) and interposition (sponge) methods were excellent surgical techniques. The interposition method may achieve earlier spasm resolution compared to the transposition method.
方法:对109例MVD患者进行分析,分为转位组(86例)和间位组(23例)。评估并比较术后1个月和1年的结果,包括痉挛缓解率,并发症,和复发。
结果:结果评估显示,干预组早期痉挛缓解率较高(66.3%vs.100%,转座vs.插入,分别,p=0.0004),尽管术后1年痉挛缓解在两组之间具有可比性(84.9%vs.95.7%,转座vs.插入,分别,p=0.2929)。并发症和复发率无明显差异。Kaplan-Meier分析表明,MVD方法在痉挛消退的持续时间上没有显着差异(p=0.4347,对数秩检验)。
结论:这项研究表明,移位(Surgicel®和纤维蛋白胶)和插入(海绵)方法都是出色的手术技术。与转座方法相比,插入方法可以实现更早的痉挛解决。
