Two Cases of Food-induced Small Bowel Obstruction Caused by Mushrooms

Abstract

Herein, we report two cases of food-induced small bowel obstruction caused by mushrooms. Case 1: A 56-year-old woman with cerebral palsy and no previous history of abdominal surgery was admitted to our hospital complaining of abdominal pain and vomiting. Abdominal computed tomography revealed small bowel dilatation and a mass with air density inside. Because the patient was unable to communicate, and considering the possibility of intestinal necrosis, we performed emergency surgery. A movable mass was observed in the ileum. The ileum was incised, and a shiitake mushroom was removed. Case 2: A 39-year-old woman without a previous history of abdominal surgery was admitted to our hospital complaining of abdominal pain and vomiting. Abdominal computed tomography revealed small bowel dilatation and a mass with air density inside. As she gave a history of having eaten sukiyaki containing mushrooms the day before, we considered the possibility of food-induced small bowel obstruction and performed emergency surgery. A soft lump was observed in the ileum. The ileum was incised, and enoki mushrooms were removed. In cases of ileus without a previous history of abdominal surgery, food-induced small bowel obstruction should be considered in the differential diagnosis.
