Schematic diagram of capsule passing through the pylorus and examination procedure of duodenum. A, The endoscopist rotated the capsule until the camera end faced the pylorus. B, In the duodenal bulb, the “360° automatic scanning” model was used during the procedure. Originally published in Jiang X, Qian YY, Liu X, et al.

The standardized gastric examination procedure. When the capsule reaches the stomach, the capsule is lifted away from the posterior wall, rotated, and advanced to the fundus (A), long shots (B), and close-ups (C) of the cardiac regions, and then the posterior wall (D), the lesser and greater curvature (E) and anterior wall (F) of the gastric body, followed by the angulus (G) and antrum (H) and finally the pylorus (I).

Gastrointest Endosc 2018;88:466-474.e1.
