Gastric Adenocarcinoma in patients with Roux-en-Y Gastric bypass: A case series

Abstract

/10.10 15 A mmo ence: . gedr@ The incidence of gastric cancer is approximately 24,000 cases per year with a mortality of 14,000 cases per year. There has been an increasing incidence of proximal gastric cancer and gastroesophageal junction cancer in the United States over the past 5–10 years [1]. Gastric cancer in patients who had previously undergone gastric restrictive surgery and gastric bypass has been reported but is rare. Seventeen case reports and series have been performed describing patients with gastric cancer after undergoing gastric bypass surgery [2]. In the majority of patients who had undergone previous Roux-en-Y gastric bypass surgery, gastric cancer developed in the excluded stomach, leading to delayed diagnosis. Unfortunately, management for these patients is difficult, given their often late diagnoses, which results in the advanced nature of their cancers when symptoms eventually develop [2]. Two cases of gastric adenocarcinoma in patients after Roux-en-Y gastric bypass will be described.
