Malignant colorectal polyps are defined as lesions that invade into the submucosa and represent early colorectal cancer (T1 by the TNM Classification of Malignant Tumors system)…

BACKGROUND: The most common complication after endoscopic mucosal resection (EMR) is delayed bleeding (DB), especially in the proximal colon…

Endoscopic ultrasound-guided gastroejejunostomy (EUS-GJ) has gained popularity in treating malignant gastric outlet obstruction (GOO). EUS-GJ has also been used to manage benign GOO with promising technical and clinical success…

BACKGROUND: G-POEM has emerged as a treatment for medically refractory gastroparesis. Safe and effective mucosal closure is necessary to avoid potential morbidity…

Management of patients with margin negative, T1-T3, N0 (stage IB–IIIA), resected gallbladder cancer (GBC) remains poorly defined. Current guidelines consider observation, chemotherapy (CT), and chemoradiation (CRT) as options…

INTRODUCTION: It is unclear whether the insertion of an axis-orienting double-pigtail plastic stent (DPS) through biliary lumen-apposing metal stents (LAMS) in EUS-guided choledochoduodenostomy (CDS) improves the stent patency…

EUS-guided gastroenterostomy (EUS-GE) is a novel method for palliating gastric outlet obstructon due to unresectable malignancies…

INTRODUCTION: Third space endoscopic procedures are becoming more widespread as a minimally invasive treatment alternative for patients. Often, patients are admitted overnight post-procedure to ensure adequate pain control, hydration, and monitoring for adverse events (AEs)…

Delayed bleeding can occur after endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) in up to 15.6% of cases. Current hemostatic methods to minimize delayed bleeding risk have limitations. Epinephrine injection effect is transient…

Resection of distal rectal lesions extending to the dentate line is technically challenging due to unique anatomical features and the ideal treatment strategy remains unclear…

Endoscopic Submucosal Dissection (ESD) in the rectum, while offering many advantages, has delayed complications such as bleeding and perforation. Some consider routine post-ESD overnight hospital observation to monitor for these complications…

BACKGROUND: Endoscopic submucosal dissection (ESD) of colorectal lesions is technically demanding and carries a significant rate of noncurative resection…

Endoscopic ultrasound-guided gallbladder drainage (EGBD) using lumen apposing metal stents (LAMS) has become a pivotal part of the management of acute cholecystitis in patients who are not surgical candidates…

BACKGROUND: Endoscopic submucosal dissection (ESD) is a widely accepted treatment option for superficial esophageal squamous neoplasms (SSN) in Asia and is supported by US society guidelines…
