磁吻合技术治疗先天性长段食管闭锁与吻合口狭窄新进展

Recent advances of magnetic compression anastomosis technique for esophageal atresia and anastomotic strictures

新生儿先天性食管长段闭锁(congenital esophageal atresia,CEA)和术后吻合口狭窄是小儿外科常见的难题,前者需要多次手术和较长的治疗周期,后者则是食管吻合术后常见的并发症。磁吻合技术(magnetic compressive anastomosis,MCA)通过磁体间压榨作用使受压组织坏死脱落并促进局部相邻组织准确对位愈合从而形成牢固的吻合口。MCA有助于实现长段食管闭锁一期吻合,并可为术后吻合口狭窄的微创治疗提供一种可行的选择。

Neonatal long-gap esophageal atresia (LGEA) and severe refractory esophageal stricture are common and challenging surgical problems in newborns.LGEA requires multi-stage operations with extended treatment periods and anastomotic stricture occurs frequently after esophageal anastomosis.Magnetic compressive anastomosis (MCA) using mated magnets with interposed compressed tissue may result in serosa-to-serosa apposition for organ anastomosis.It creates solid anastomostic connections for LGEA and refractory esophageal stricture in children.
