Gastric Cancer After Laparoscopic Sleeve Gastrectomy: a Case Report and Literature Review

Abstract

The number of bariatric surgeries performed worldwide over the last decades has increased. After surgery, patients experience significant weight loss, improvement, and/or remission of several obesity-associated diseases [1, 2]. Due to the effect on several obesity-associated risk factors for cancer, bariatric surgery reduces the incidence of various types of hormone-dependent tumors such as breast, endometrial, and colon cancer [3]. Concerning upper gastrointestinal cancers, obesity has been associated with esophageal and adenocarcinoma of gastric cardia [4, 5]. These tumors are particularly relevant in our country since Chile has an intermediate risk for gastric cancer (GC) development, as shown by an age-standardized incidence rate (ASIR) of GC mortality of 10–20/100.000 inhabitants [6]. Accordingly, preoperative upper gastrointestinal endoscopy (UGE) has been routinely performed in patients undergoing bariatric surgery at our institution [7]. Gastroesophageal cancer after BS has been scarcely reported over the last years, and the vast majority of published articles are sporadic case reports, mainly after laparoscopic sleeve gastrectomy (SG) (Table 1) [8–17]. Here, we report a male patient who presented with an advanced GC 6 years after SG. Case Report
