The diagnostic performance of endoscopic ultrasound–guided fine-needle aspiration is strongly dependent on the availability of an onsite cytopathologist. The diagnosis of some rare tumors may require ancillary testing for which…
Shyam Varadarajulu, MD, Editor Robert H. Hawes, MD, Editor There has been a significant shift in the practice of EUS-guided tissue acquisition since the technique was first reported 21 years…
Charles J. Lightdale, MD, Consulting Editor Endoscopic ultrasound (EUS) started out as primarily an imaging technique, but it soon became clear that EUS-guided fine-needle aspiration (FNA) for tissue acquisition would…
Endoscopic submucosal dissection (ESD) is a well-established advanced mucosal resection technique used in Japan, where it originated, and some other Asian countries. The technical difficulty and potentially higher rates of…
Endoscopic submucosal dissection (ESD) improves the quality of life of patients with early gastric cancer (EGC) and dysplasia by preserving gastric function. ESD in the treatment of EGC and dysplasia…
Induced pluripotent stem (iPS) cells have captured the world’s attention and directed an unprecedented focus on regenerative medicine. The potential of iPS cells to aid in the development of new…
Submucosal endoscopy with a mucosal flap (SEMF) safety valve technique is a global concept in which the submucosa is a free working space for endoscopic interventions. A purposefully created intramural…
Peroral endoscopic myotomy (POEM) is an evolving minimally invasive endoscopic surgical procedure, with no skin incision, intended for long-term recovery from symptoms of esophageal achalasia. POEM was developed based on…
The number of medical facilities that perform colorectal endoscopic submucosal dissection (ESD) has been growing, and its effectiveness has been increasingly reported in recent years. Indications approved by the Japanese…
Duodenal endoscopic submucosal dissection (ESD) is technically difficult due to the unique anatomic features. The risks include intraprocedural complications, delayed bleeding, and perforation. A small-caliber-tip transparent hood is useful. Mechanical…
