A 75-year-old woman experienced nausea 7 months prior and had lost 9 kg over 3 months.

A 74-year-old woman presented with dysphagia. EGD at a previous hospital showed a giant pedunculated polyp from the entrance of the esophagus to the esophagogastric junction.

Endoscopic hemostasis is an essential skill for endoscopists and has been the first-line treatment.

Endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma (ESCC) has been widely performed.

Periampullary perforation has a high mortality rate.

Endoscopic submucosal dissection (ESD) allows for en bloc resection of various lesions of the GI tract.

Accessing the bypassed portion of the stomach and small bowel for endoscopic interventions in Roux-en-Y gastric bypass (RYGB) is challenging.

Endoscopic adventitial dissection (EAD) is a novel resection technique that involves dissection in the “fourth space,” the space between the outer longitudinal muscle and the tunica adventitia of the rectum.

EUS-guided hepaticogastrostomy (EUS-HG) provides endoscopic biliary drainage when conventional techniques are not feasible.

Endoscopy in infants and children requires different equipment because of the difference in size and weight as compared to adults.

EndoClot Polysaccharide Hemostatic System (EndoClot PHS; Micro-Tech Europe, Dusseldorf, Germany) is a starch-derived compound that consists of biocompatible absorbable hemostatic polysaccharides that absorb water when in contact with blood or liquids, creating a gelled matrix over the bleeding lesion.

The X-Tack Endoscopic HeliX Tacking System (Apollo Endosurgery, Austin, Tex, USA) is a novel through-the-scope suture-based device approved for tissue approximation of mucosal defects. 

A 56-year-old man presented with painless jaundice. An outside CT scan reported a pancreatic head mass.

Peroral endoscopic myotomy (POEM) is a safe and effective technique for the management of achalasia and other nonachalasia motility disorders.

GI stromal tumors (GISTs) typically arise from the muscularis propria layer and are commonly seen in the stomach, although they can occur anywhere along the GI tract.

We share here the case of a 67-year-old man who presented to the emergency department for evaluation of bloating, chills, and dyspepsia for 2 weeks.

Direct peroral cholangioscopy (DPOC) is a valuable diagnostic and therapeutic tool for various biliary disorders because it allows direct endoscopic visualization of biliary lumen and mucosal abnormalities. 

GI bleeding because of peptic ulcer disease is a well-described entity in its diagnosis and management.

As various devices and techniques emerge, colorectal endoscopic submucosal dissection (ESD) has become a relatively safe procedure despite the anatomical difficulty.

A 67-year-old man with a history of total gastrectomy followed by Roux-en-Y esophagojejunostomy reconstruction in the setting of gastric adenocarcinoma presented with right-upper-quadrant pain and an abnormal liver function test (LFT) (aspartate aminotransferase 389, alanine aminotransferase 273, alkaline phosphatase 297, total bilirubin 8.70).

With the advancements in endoscopic resection techniques, subepithelial tumors (SETs) can be removed by transnatural orifice endoscopy with minimal invasiveness.

Intraductal papillary mucinous neoplasms of the pancreas (IPMNs) are increasingly diagnosed tumors that are characterized by endoluminal papillary projections of mucin-producing ductal epithelium, leading to a dilatation of the ducts it develops within.

Dropped gallstones (DGS) are unable to be retrieved in 2% of cholecystectomy cases.

EUS-guided gastroenterostomy (EUS-GE) using lumen-apposing metal stents (LAMSs) has emerged as a safe, minimally invasive modality for the treatment of gastric outlet obstruction (GOO).
