Therapeutic endoscopic ultrasonography (EUS) procedures using the forward-viewing convex EUS (FV-EUS) have been reviewed based on the articles reported to date. The earliest reported procedure is the drainage of pancreatic pseudocysts using FV-EUS. However, the study on drainage of pancreatic pseudocysts focused on showing that drainage is possible with FV-EUS rather than leveraging its features. Subsequently, studies describing the characteristics of FV-EUS have been reported. By using FV-EUS in EUS-guided choledochoduodenostomy, double punctures in the gastrointestinal tract can be avoided. In postoperative modified anatomical cases, using the endoscopic function of FV-EUS, procedures such as bile duct drainage from anastomosis, pancreatic duct drainage from the afferent limb, and abscess drainage from the digestive tract have been reported. When a perpendicular puncture to the gastrointestinal tract is required or when there is a need to insert the endoscope deep into the gastrointestinal tract, FV-EUS is considered among the options.
基于迄今报道的文章，对使用前视凸阵超声内镜（FV-EUS）的治疗性超声内镜检查（EUS）程序进行了综述。最早报道的程序是使用FV-EUS进行胰腺假性囊肿引流。然而，关于胰腺假性囊肿引流的研究主要集中在证明FV-EUS能够进行引流，而非利用其特性。随后，有报道描述了FV-EUS的特征。在超声内镜引导下的胆总管十二指肠吻合术中使用FV-EUS，可以避免在胃肠道进行双穿刺。在术后改良解剖病例中，利用FV-EUS的内镜功能，已报道了诸如吻合口胆管引流、输入袢胰管引流以及消化道脓肿引流等程序。当需要对胃肠道进行垂直穿刺或需要将内镜深入插入胃肠道时，FV-EUS被视为选择之一。
