Obesity is known to be epidemiologically associated with malignancy. Although there is an increasing global number of bariatric surgeries, the relationship between bariatric surgery and esophagogastric cancers is not well understood. Diagnosis of esophagogastric cancers following bariatric surgery is challenging because the presentation tends to be nonspecific and may be perceived as usual postoperative symptoms in bariatric patients. Therefore, the early diagnosis requires a high index of suspicion. In addition, endoscopic investigation of the excluded stomach after a Roux-en-Y gastric bypass or a one-anastomosis gastric bypass is technically challenging, which further complicates the diagnosis. The aim of this study is to review the current evidence in the literature on esophagogastric cancers following bariatric surgery.
