BACKGROUND: There is a lack of data on training benchmarks to define competence in colorectal EMR (C-EMR) among advanced endoscopy trainees (AETs). Previous pilot data from our group demonstrated a relatively low proportion of AETs achieve competence on key cognitive and technical aspects of C-EMR…

BACKGROUND: Video analysis has emerged as a potentially strategy for performance assessment of specialized techniques where local expertise and mentorship are limited…

Acute variceal bleeding (AVB) is a major cause of death in cirrhotic patients. We developed and internally validated a pragmatic model to predict the individualized risk of 30-day readmission with recurrent AVB in liver cirrhosis patients…

Recently macroscopic-onsite evaluation (MOSE) technique for Endoscopic Ultrasound guided Tissue acquisition (EUS-TA) for solid gastrointestinal lesions has been advocated to provide high diagnostic accuracy in settings where rapid- onsite evaluation is not available…

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…

Non-variceal upper gastrointestinal bleeding (NVUGIB) accounts for a significant number of patient visits to emergency rooms and remains a major cause of mortality and morbidity worldwide. The re-bleeding rates of NVUGIB after endoscopic treatment within 72 hours have been reported to be up to 25%…

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

BACKGROUND: Idiopathic gastroparesis (IG) is an increasingly prevalent subtype of gastroparesis and causes significant morbidity and decreased quality of life…

Endoscopic retrograde cholangiopancreatography (ERCP) has become an important therapeutic modality for management of pancreaticobiliary diseases. Post-ERCP perforation, most commonly type 2, is one of the most feared complications of ERCP…

While gastric per-oral endoscopic myotomy (G-POEM) of the pylorus has shown promising results in enhancing the quality of life (QoL) for patients with gastroparesis (GP), evidence supporting its sustained benefits over time is limited…

INTRODUCTION: G-POEM is a promising therapy in patients with GP. Functional lumen imaging probe (FLIP) is used to measure pylorus distensibility. However, current FLIP balloon is not designed for the pylorus, and it measures distensibility in a non-isobaric fashion…
