This video shows diffuse signet ring gastric cancer in the remnant stomach of a patient who had had a roux-en-Y gastric bypass (RYGB) many years previously and presented with a gastric outlet obstruction. This endoscopy was conducted via a gastrostomy tube in the remnant stomach using a slim (4.5mm) endoscope.
