According to the Brazilian health authorities, around 2,000 new cases of gastric cancer emerge in Brazil per year (Instituto Nacional de Câncer José Alencar Gomes da Silva, 2014). Indeed, gastric cancer constitutes the second most common cause of cancer-related mortality worldwide and 95% of such malignancies are adenocarcinomas (De Roover et al., 2006, and Clark et al., 2006). Roux-en-Y gastric bypass (RYGB) is a procedure frequently employed in bariatric surgery but restricted access to the excluded stomach means that discovery of gastric lesions is difficult, and diagnosis and treatment may be delayed. We report herein a case of gastric adenocarcinoma in the excluded stomach of a patient submitted to RYGB with the purpose of illustrating the difficulty of diagnosing and treating this rare condition.

据巴西卫生当局称，巴西每年约有2000例新发胃癌病例（巴西国立癌症研究所何塞·阿伦卡尔·戈麦斯·达席尔瓦，2014年）。事实上，胃癌是全球癌症相关死亡的第二大常见原因，95%的此类恶性肿瘤为腺癌（德罗弗等人，2006年；克拉克等人，2006年）。Roux-en-Y胃旁路术（RYGB）是减肥手术中常用的一种术式，但由于难以触及被旷置的胃，胃病变的发现较为困难，诊断和治疗可能会延迟。我们在此报告一例接受RYGB手术患者被旷置胃中发生胃腺癌的病例，旨在说明诊断和治疗这种罕见病症的困难。
