Bezoars are large aggregates of ingested material ranging from hair, fruit fibers, and others [1]. Radiographically, bezoars can mimic gastric neoplasms [2]. Complications from bezoars include small bowel obstruction to life-threatening bowel perforation [3]. Majority of patients with bezoars have some history of abdominal surgery [4,5]. While several cases of bezoars have been reported after gastro-duodenal surgeries, this is the first report of bezoar formation due to pyloric-exclusion gastrojejunostomy.

Case Presentation

A 19-year-old woman with history of abdominal trauma during infancy requiring pyloric-exclusion gastrojejunostomy presented with worsening abdominal pain, nausea, vomiting and weight loss over one month. Abdominal computed tomography (CT) revealed a large ovoid intraluminal mass in the duodenal bulb measuring 5.3 x 5.4 x 7.4 cm, and magnetic resonance imaging (MRI) confirmed a large laminated-appearing mass in the second part of the duodenum (Figure 1a and 1b). Esophagogastroduodenoscopy (EGD) revealed gastroesophageal junction at 37 cm, and unremarkable gastric mucosa. Upon traversing the gastrojejunostomy, the efferent limb was unremarkable up to 40 cm. At 70 cm distance in the afferent limb, the large bezoar containing food material (Figure 1c) was seen extending from the third portion of the duodenum to the proximal jejunum (Figure 1d). We found that her pyloric-exclusion was never reversed; suggesting likely bezoar formation due to chronic reflux from the jejunum into duodenum.

b. Coronal view of T2-weighted magnetic resonance imaging showing the mass in the second part of the duodenum with laminated appearance with a heterogeneous low signal alteration and central fluid signal.

c. Upper endoscopy revealing a large yellow colored bezoar in the proximal jejunum to second portion of the duodenum. The gastric body showed a gastrojejunal anastomosis and proximally altered pylorus with a minimal opening, confirming prior pylorus exclusion surgery.

The patient required laparoscopic pyloroplasty for removal of the bezoar. At 4-month follow-up, she was gaining weight and asymptomatic.



Risk factors for bezoar formation include psychiatric illnesses, hypomotility disorders, diabetes, previous gastro-duodenal surgeries, and dietary habits [1,4,5]. Additionally, most patients report a history of abdominal surgery. On imaging, bezoars are usually round, ovoid, and mottled, however they can also have a laminated appearance [6]. Pyloric-exclusion gastrojejunostomy is performed when duodenal ischemia is suspected such as in abdominal trauma. In cases where the pyloric exclusion is not reversed, patients are at risk of bezoar formation due to reflux of food material back into the duodenum or enterolith formation.
