Department of Gastroenterology, Saitama Medical University International Medical Center, 1397-1, Yamane, Hidaka, Saitama 350-1298, Japan.

Endoscopic retrograde cholangiopancreatography (ERCP) is considered to be the gold standard for diagnosis and interventions in biliopancreatic diseases. However, ERCP in patients with surgically altered anatomy (SAA) appears to be more difficult compared to cases with normal anatomy. Since the production of a balloon enteroscope (BE) for small intestine disorders, BE had also been used for biliopancreatic diseases in patients with SAA. Read More

The Role of Endoscopy in Small Bowel Neuroendocrine Tumors.

Clin Endosc 2021 Apr 1. Epub 2021 Apr 1.

Division of Gastroenterology, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

Small bowel neuroendocrine tumors (NETs) represent approximately one-third of NETs of the gastrointestinal tract, and their incidence is increasing. When determining if endoscopic resection is appropriate, endoscopic ultrasound is used to assess the lesion size and depth of invasion for duodenal NETs. A number of techniques, including endoscopic mucosal resection (EMR), band-assisted EMR (band-EMR), endoscopic submucosal dissection (ESD), and over-the-scope clip-assisted endoscopic full-thickness resection (EFTR), have been studied; however, the best technique for endoscopic resection remains unclear.

Management of Non-Variceal Upper GI Bleeding in the Geriatric Population: An Update.

Curr Gastroenterol Rep 2021 Mar 25;23(4). Epub 2021 Mar 25.

Department of Medicine, Division of Gastroenterology & Nutrition, Long School of Medicine, UT Health San Antonio, San Antonio, TX, 78229-3900, USA.

Purpose Of Review: Upper gastrointestinal (GI) bleeding is a significant cause of morbidity and mortality in the geriatric (age > 65 years) population and presents a unique management challenge in the context of multiple medical comorbidities, polypharmacy, and increased risk of adverse outcomes and is confounded by an increased prevalence of obscure GI bleeds. A review of relevant guidelines, literature, and personal observations will enhance management strategies in the elderly.

Recent Findings: Non-variceal bleeding represents a significant proportion of upper GI bleeding (UGIB) in geriatric patients. Read More
