Fig. 1 Diagrams depicting: a the upper gastrointestinal tract anatomy following Roux-en-Y gastric bypass; b,c the location of the transgastric lumen-apposing metal stent (LAMS) and the path of the endoscope after: b gastrogastric stent placement; c jejunogastric stent placement.

Fig. 3 Differences in lesion approach between conventional and multibending endoscopes. a,c Approaching the lesser curvature of the gastric body (a) or fundus (c) with a conventional endoscope is difficult, as the knife is at an angle and may make contact with the muscle layer. b,d By using a multibending endoscope, the knife is placed parallel to the muscle layer and in close proximity to the lesion at the lesser curvature of the gastric body (b) or the fundus (d).

“Art in endoscopy” is an initiative of four gastroenterologists in training that aims to display examples of the incidentally beautiful images that are sometimes encountered in regular endoscopic practice.

Fig. 1 Radiographic images of direct endoscopic ultrasound-guided biliary drainage (EUS BD) in: a, b patient #1, who had biliopancreatic diversion with distal gastrectomy and a common bile duct stone, showing: a hepaticogastrostomy performed for drainage and future access at index EUS-BD; b antegrade passage of a mechanical lithotriptor through the hepaticogastric stent at the follow-up procedure; c patient #2, who had biliary obstruction by metastatic breast cancer, showing a stricture on the index EUS cholangiogram (arrowhead) 6 months after duodenal stent placement across the papilla; d patient #3, who had left-sided cholangitis 2 weeks after right-sided ERCP drainage of a bilateral Klatskin tumor, showing a left hepatic duct stricture (thin arrows) and (inset) pus draining into the stomach after hepaticogastrostomy.
