There are various reconstruction techniques that are used after upper gastrointestinal surgery. In recent years, opportunities for endoscopic diagnosis and treatment have been increasing in patients undergoing gastrointestinal surgery. With the advent of interventional endoscopic ultrasound (IV‐EUS), various procedures have been developed mainly for patients in whom endoscopic retrograde cholangiopancreatography is difficult to carry out. Indications for such procedures are expanding. IV‐EUS for surgically altered anatomy (SAA) includes EUS‐guided fine‐needle aspiration, biliary interventions (e.g. biliary drainage, treatment of bile duct stricture, removal of bile duct stones, and the rendezvous technique), and pancreatic interventions (e.g. rendezvous technique after Whipple surgery). In addition, there have been reports of various EUS‐related procedures using a forward‐viewing curved linear‐array echoendoscope that are carried out for postoperative intestinal tract reconstruction. Although interventional EUS is a useful therapeutic procedure for SAA, there are still no dedicated devices, and standardization of the procedure is warranted.

手术改变解剖结构患者的介入性 EUS：技术和文献回顾

上消化道手术后使用了多种重建技术。近年来，接受胃肠手术的患者进行内镜诊断和治疗的机会越来越多。随着介入性内镜超声 (IV-EUS) 的出现，主要针对难以进行内镜逆行胰胆管造影的患者开发了各种手术。此类手术的适应症正在扩大。用于手术改变解剖结构 (SAA) 的 IV-EUS 包括 EUS 引导的细针穿刺、胆道干预（例如胆道引流、胆管狭窄的治疗、胆管结石去除和会合技术）和胰腺干预（例如会合术） Whipple 手术后的技术）。此外，有使用前视曲线线阵回声内窥镜进行各种 EUS 相关手术的报道，这些手术用于术后肠道重建。虽然介入性 EUS 是 SAA 的一种有用的治疗方法，但仍然没有专用的设备，并且有必要对程序进行标准化。
