A prospective study involving eight institutions was performed, incorporating 640 cases of carpal tunnel release using a dual portal endoscopic technique. The original transbursal technique described by Chow was used in 110 cases (17%), and the modified extrabursal technique was used in 530 cases (83%). An overall complication rate of 11% was found in the patients in whom the transbursal technique was used, compared with 2.2% in the patients in whom the extrabursal technique was used. The return-to-work status was followed in 291 cases (199 non-worker's compensation cases and 92 worker's compensation cases). The worker's compensation patients returned to work in an average of 57 days, compared with 22 days for non-worker's compensation patients. This study suggests the extrabursal dual portal endoscopic technique is associated with fewer complications than the transbursal approach, and patients covered by worker's compensation return to work later than non-worker's compensation patients.
一项涉及八个机构的前瞻性研究开展了，纳入了640例采用双入路内镜技术进行腕管松解术的病例。Chow所描述的原始经腱鞘技术用于110例（17%），改良的经腱鞘外技术用于530例（83%）。采用经腱鞘技术的患者总体并发症发生率为11%，而采用经腱鞘外技术的患者为2.2%。对291例（199例非工伤赔偿病例和92例工伤赔偿病例）的复工情况进行了跟踪。工伤赔偿患者平均57天复工，而非工伤赔偿患者为22天。这项研究表明，经腱鞘外双入路内镜技术比经腱鞘方法的并发症更少，且工伤赔偿患者比非工伤赔偿患者复工更晚。
