Endoscopic Ultrasound-guided Gastroenterostomy: A Promising Alternative to Surgery.

Abstract

Recently, with the advancement of techniques, endoscopic ultrasound-guided therapies have shown distinct advantages, especially in relieving benign and malignant gastric outlet obstruction (GOO), as well as in postoperative pancreaticobiliary diseases. Herein, we present five currently used approaches in endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using lumenapposing biflanged metal stents (LAMS), along with several examples of LAMS-based EUS treatment of pancreaticobiliary diseases. Compared with traditional treatment methods, EUS-guided procedures have – to some degree – shown higher success rates, both technical and clinical. Moreover, EUS-guided therapies reduce the risk of multiple surgical adverse events, including delayed gastric emptying, prolonged hospital stay, increased costs, and delay in cancer treatment. Particularly in terms of postoperative pancreaticobiliary diseases, EUS-guided therapy has assumed an essential role as a treatment option in cases where traditional methods are difficult to perform. Nevertheless, EUS-guided gastrointestinal procedures are still relatively new, with some clinical failures, and additional prospective clinical trials are warranted.
