Diagnosis of Gastric Cancer in the Excluded Stomach After RYGB by Jejunogastrostomy Using a LAMS.

For patients after bariatric surgery, diagnosis of gastric cancer is a challenge. We present a patient after Roux-en-Y gastric bypass with upper abdominal pain and abnormal computed tomography scan with diffuse wall thickening of the gastric antrum. Various biopsy techniques have been described, with surgical (laparoscopic) exploration being the most common. We were able to successfully diagnose gastric cancer in the excluded stomach by biopsy using a jejunogastrostomy, which proved to be safe and effective.
