Development of clinical celiac disease after pancreatoduodenectomy: a potential complication of major upper abdominal surgery

Abstract

Background: Celiac disease is a gluten-induced disease of global malabsorption. There is a subset of patients with celiac disease who are free of major symptoms but who have typical damage to the intestinal mucosa (silent disease). We present the case of a 50-year-old white woman with no clinical symptoms of celiac disease who developed diarrhea and weight loss 12 weeks after a pancreatoduodenectomy for ampullary cancer.

Methods: Microbiological and biochemical examination of the feces did not provide clues useful to diagnosis, and diarrhea was not affected by pancreatic enzyme replacement or administration of antiperistaltic drugs.

Results: Review of the pathologic specimen and blood tests were compatible with celiac disease.

Conclusion: This clinical scenario illustrates that subclinical celiac disease may be an underdiagnosed cause of malabsorption after major upper gastrointestinal surgery and should be considered in the differential diagnosis of diarrhea after pancreatoduodenectomy.
