Using a curved linear array echoendoscope, the gastric fundus can be imaged with the transducer positioned in the distal esophagus. Transesophageal access offers an alternative route to treat gastric fundal varices under EUS-guidance without entering the stomach. This anatomical cartoon illustrates transesohageal access to the gastric fundus [...]
