BACKGROUND: There is growing evidence that aprepitant can be helpful for patients with cyclic vomiting syndrome (CVS) and cannabinoid hyperemesis syndrome (CHS), but experience in children remains limited…

BACKGROUND: Rumination syndrome (RS) is increasingly recognized in the pediatric population, however, there is no existing tool to measure symptom severity…

SOCIETY: ASGE

BACKGROUND: Recently, high rates of post-peroral endoscopic myotomy (POEM) gastroesophageal reflux disease have been reported. A novel POEM with fundoplication (POEM-F) has been described to address this issue…

HREM is the gold standard for esophageal motility disorders with a PPV 96%, sensitivity 100% and specificity 98%. This study compares the barium esophagogram results with HREM in pediatric patients. METHODS : Observational, retrospective, test-retest concordance study…

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…

Current guidelines advise esophagectomy for submucosal esophageal adenocarcinoma (T1b EAC). However, data from retrospective studies suggest that endoscopic follow-up (FU) may be a valid alternative in patients without signs of lymph node metastases (LNM) at baseline…

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

Training in interventional endoscopy is offered by interventional endoscopy fellowship programs (IEFPs) not accredited by the ACGME. The number of these programs has increased exponentially with a concurrent increase in the breadth and complexity of these procedures…

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: while minimally invasive, EUS is limited in its ability to clearly characterize intraductal lesions…

BACKGROUND: Hybrid endoscopic submucosal dissection (H-ESD), which incorporates ESD with endoscopic mucosal resection, has been developed and is increasingly utilized to overcome the technical complexity of conventional ESD (C-ESD)…

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…

BACKGROUND: Endoscopic impedance planimetry (FLIP) has been used to evaluate the pyloric physiologic parameters after G-POEM for refractory gastroparesis; yet data on this technology is still limited…

BACKGROUND: Sleeve gastrectomy (SG) is one of the most commonly performed bariatric procedures worldwide. Gastroesophageal reflux disease (GERD) is a major concern in patients undergoing SG and is a risk factor for Barrett's esophagus (BE)…

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…

BACKGROUND: Esophageal stenosis is a potential risk after endoscopic submucosal dissection (ESD), with incidence ranging from 70-90% among those with mucosal defects involving more than three-quarters of the circumference of the esophagus…

BACKGROUND: Esophageal epiphrenic diverticula (ED) are rare pulsion-type diverticulum in the distal esophagus that can develop in the setting of an underlying esophageal motility disorder as a result of the contractile dyscoordination between the distal esophagus and lower esophageal sphincter (LES…
