Post written by Dr. Harry Aslanian from the Section of Digestive Diseases at Yale University. We thought it would be interesting for non-endosonographers to see how easily and quickly ROSE can provide diagnostic information. Among endosonographers, there is local variation in cytopathologists’ comfort level with pancreas cytology and variable interest in ROSE. While some centers have …

Post written by Vivek Kumbhari, MD, at Johns Hopkins Hospital in Baltimore, Maryland, USA. Weight regain after Roux-en-Y gastric bypass (RYGB) is common and is partially attributable to dilatation of the gastrojejunostomy (GJ), which diminishes the restrictive capacity of RYGB. Endoscopic revision of dilated GJ, called transoral outlet reduction (TORe), has been proved effective in …

Post written by Sergio Cadoni from the Digestive Endoscopy Unit at St. Barbara Hospital in Iglesias, Italy. Water exchange (WE) is the least painful insertion method during colonoscopy. However, its impact on postcolonoscopy discomfort has not been well-described. Carbon dioxide (CO2) insufflation has been consistently shown to decrease postcolonoscopy discomfort. We compared postcolonoscopy outcomes of various combinations …

Post written by Pujan Kandel, MD, from the Division of Gastroenterology, Mayo Clinic, Jacksonville, Florida. This was a single center retrospective case control study. All the consecutive samples from EUS-FNB-SCs were matched in a 1:3 ratio by the lesion site (e.g. pancreatic head) and needle gauge (i.e. 19, 22, and 25 gauge) to recent random …

Post written by Rohit Sinha, MBBS, MRCP, PgDip, from the Royal Infirmary and The University of Edinburgh, Edinburgh, United Kingdom. We wanted to evaluate the efficacy of Hemospray in conjunction with established hemostatic endo-therapy in a high-risk nonvariceal upper GI bleeding setting. There was no evidence about the efficacy and outcome of combination therapy (Hemospray …

Ming-Yan Cai, MD, from the Endoscopy Center and Endoscopy Research Institute, Zhongshan Hospital, Fudan University, Shanghai, China, presents this video case. During a regular EGD exam, using a magnifying scope with narrow-band imaging (NBI) function, we observed a very interesting pattern of Ancylostoma duodenale. A male worm was coiled around a female one and the …
