RESUMEN
Esophageal candidiasis is the most common disease among all candida infections of the gastrointestinal tract, and generally develops in immunocompromised patients. The prevalence of esophageal candidiasis has increased in patients undergoing antibiotic therapy, diabetes, adrenal dysfunction, alcohol intoxication, old age, esophageal injury, esophageal stasis, gastric surgery, and acid suppressive therapy. However, the overall prevalence is not higher than that of immunocompromised patients. Gastric candidiasis is uncommon because of the strong acidity of the gastric juices. The most common clinical setting for gastric candidiasis is in patients with neoplastic disease. However, there are some case reports suggesting an increase in the prevalence of gastric candidiasis after gastric ulcer therapy with surgery or acid suppressive agents. Delayed gastric emptying, increased intragastric pH, and reflux of the duodenal contents into the stomach are factors indicative of the pathophysiology of gastric candidiasis after gastric surgery. We encountered a case of aggravated esophageal candidiasis and the formation of a gastric yeast bezoar following a gastric outlet obstruction due to a duodenal stenosis. We herein report this case along with an overview of the relevant literature.
