Endoscopic ultrasound: An all in one technique vibrates virtually around the whole internal medical field


The imaging obtained by endoscopic ultrasound (EUS) has improved our understanding of many disease states of the digestive tract. It was mostly utilized by gastroenterologists and surgeons. In this article, we highlight some of the indications and applications that may be noticed by other specialists such as non-small cell lung cancer (by a special EUS technique, i.e., endobronchial ultrasound), pancreatic neuroendocrine tumors, kidney and adrenal masses, rectosigmoid endometriosis, celiac plexus neurolysis and pseudocyst drainage.

Endoscopic ultrasound-guided pancreatic pseudocyst drainage with lumen-apposing metal stents or plastic double-pigtail stents: A multifactorial analysis



To compare the efficiency of plastic and metal stents for symptomatic pancreatic pseudocyst (PP) drainage and analyze other main associated factors that affect the outcome of drainage therapy.


Rates of technical and clinical success, procedure-related side effects (hemorrhage, stent migration, and cyst rupture), reinterventions, and duration of hospital stay.


There were 52 patients, 40 patients underwent plastic stent placement and 12 patients underwent lumen-apposing metal stent (LAMS) placement. The total rate of technical success was 100%. The total rate of clinical success was 100%. The total rate of adverse events was 7.7% (4/52). On multiple logistic regression analysis, the use of plastic stents (P < 0.05, Exp B = 12.168) and the presence of a large cyst (P < 0.05, Exp B = 1.036) were shown to significantly increase the risk of reintervention. On multivariate linear regression analysis, etiology of pseudocyst (P < 0.05, B = −8.427, −9.785, −5.514) was associated with prolonged hospital stent, while stent type was not shown be a factor (P > 0.05).


Both plastic and LAMSs are proven to be highly efficient in PP drainage. The LAMS is superior in preventing complications such as migration and cyst leakage and reducing the rate of reintervention.

Endoscopic Ultrasound-guided Gastroenterostomy: A Promising Alternative to Surgery


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.
