A 10-center randomized prospective multicenter study of endoscopic release of the carpal tunnel was carried out. Surgery was performed with a new device for transecting the transverse carpal ligament while control hands were treated with conventional open surgery. There were 122 patients in the study; 25 had carpal tunnel surgery on both hands and 97 had surgery on one hand. Of the surgical procedures, 65 were in the control group and 82 were in the device group. The endoscopic device was coupled to a fiberoptic light and a video camera. A trigger-activated blade was used to incise the transverse carpal ligament. After surgery, the best predictors of return to work and to activities of daily living were strength and tenderness variables. For patients in the device group with one affected hand, the median time for return to work was 21 1/2 days less than that for the control group. Two patients treated with the endoscopic device required reoperation by open surgical decompression; only one of these had incomplete release with the device. Two patients in the device group experienced transient ulnar neurapraxia.
开展了一项关于腕管内镜松解术的10中心随机前瞻性多中心研究。手术采用一种用于横断腕横韧带的新设备进行，而对照手则采用传统开放手术治疗。该研究共有122例患者；25例患者双手均接受了腕管手术，97例患者单手接受了手术。在手术操作中，65例在对照组，82例在设备组。内镜设备与光纤灯和摄像机相连。使用触发激活刀片切开腕横韧带。术后，恢复工作和日常生活活动的最佳预测指标是力量和压痛变量。对于设备组中单手受累的患者，恢复工作的中位时间比对照组少21.5天。两名接受内镜设备治疗的患者需要通过开放手术减压进行再次手术；其中只有一名患者使用该设备时松解不完全。设备组中有两名患者出现短暂性尺神经失用。
