Cardia Gastric Cancer in the Gastric Pouch 5 Years after Gastric Bypass: A Case Report

摘要

Background Roux-en-Y gastric bypass (RYGB) is one of the most frequently performed bariatric procedures worldwide. Remnant gastric cancer after RYGB is a rare complication. There were about seventeen cases reported in the world. The location of the tumor in these cases occurs mainly in the gastric antrum, followed by the body, then the pylorus and linitis plastica, and the last was fundus of the stomach. To the best of our knowledge, this is the first case that gastric cancer located in the cardia of stomach after RYGB. Case Report A 68-year-old male patient had chronic esophagitis, bile reflux gastritis, and erosive antral gastritis 5 years after RYGB and now developed to aggressive carcinoma in the gastric pouch. In spite of having chemotherapy and traditional Chinese medicine therapy, the patient died of multiple organ failure after 15 months. Conclusions This case report highlights the importance to have gastroscopy to observe the proximal small remnant stomach after RYGB in long-term follow-up. Attention must be paid when patients develop symptoms like abdominal pain or excessive weight loss after RYGB. For patients at high risk such as those who have a family history of gastric cancer or presenting abnormal levels of tumor markers should rather undergo Sleeve Gastrectomy plus Jejunojejunal Bypass (SGJB) instead of RYGB.
