Introduction
Malabsorption syndrome encompasses a spectrum of gastrointestinal disorders characterized by impaired absorption of nutrients, leading to various clinical manifestations. Endoscopic and histological evaluations play crucial roles in diagnosing underlying etiologies, including celiac disease.
Aims & Methods
This retrospective study aimed to analyze the clinical presentation, endoscopic findings, and histological yield in patients with malabsorption syndrome, focusing on the subset exhibiting villous atrophy to investigate the prevalence of celiac disease. We conducted a retrospective analysis of 100 patients with malabsorption syndrome who underwent endoscopic evaluation between January 1, 2023, and December 31, 2023. Clinical data, endoscopic findings, and histological results were collected and analyzed.
Results
Among the 100 patients, 60 were males and 40 were females. Common presenting symptoms included fatigue (33 patients), recurrent mouth ulcers (15 patients), bloating (12 patients), diarrhea (24 patients), and abdominal discomfort (16 patients). Endoscopic findings revealed normal mucosa in 34 patients, decreased height of duodenal folds in 24, and fissured mucosa in 42. Histological analysis showed increased intraepithelial lymphocytes in 36 patients, crypt hyperplasia with increased intraepithelial lymphocytes in 20, partial villous atrophy in 22, subtotal villous atrophy in 12, and total villous atrophy in 10 patients. Giardia was detected in histological specimens from 4 patients with partial villous atrophy. Interestingly, only 12 patients had positive celiac serology despite a substantial number exhibiting villous atrophy on histological examination.
Conclusion
This study highlights the diverse clinical presentation and histological spectrum of malabsorption syndrome. Despite significant villous atrophy, celiac disease was diagnosed in only a minority of patients, suggesting the need for further investigation into the etiology of villous atrophy in this subset of patients.
