Increased risk of surgery in undiagnosed celiac disease.

The diagnosis of celiac disease patients may be delayed by misdiagnosis. Our aim was to evaluate in celiac patients the prevalence of surgery before diagnosis. Two hundred forty-four adult celiac patients and 232 controls were retrospectively investigated for surgery before diagnosis of celiac disease. The prevalence of surgery was increased in celiac patients versus controls (P = 0.001). Frequency of appendectomy (P = 0.0001), tonsillectomy (P = 0.009), and hernia repair (P = 0.05) were increased in celiac patients versus controls. Appendectomy was related to anemia (P = 0.006) and abdominal pain (P = 0.005); tonsillectomy was related to diarrhea (P = 0.02) and weight loss (P = 0,04). Appendectomy was elective in 73% of celiac patients and in 46% of controls. Cosmetic surgery was increased in celiac patients versus controls (P = 0.058). In conclusions, surgery before celiac disease diagnosis is increased in celiac patients compared to controls, as a result of doctors' misdiagnosis and/or poor health status, which increases the demand for medical intervention. The frequency of cosmetic surgery in celiac patients may berelated to impaired psychological profile of patients.
