Small intestinal mucosal abnormalities using video capsule endoscopy in intestinal lymphangiectasia

Area of Science:

• Gastroenterology
• Endoscopy
• Rare Diseases

Background:

• Intestinal lymphangiectasia (IL) is a rare protein-losing enteropathy stemming from lymphatic disorders.
• Existing literature on VCE findings in IL is limited, primarily consisting of case reports and series.

Purpose of the Study:

• To characterize VCE findings of small intestinal mucosal abnormalities in IL patients.
• To explore the correlation between clinical and VCE characteristics in IL.

Main Methods:

• A retrospective analysis of consecutive IL patients who underwent VCE.
• Classification of cases into 'white villi' and 'non-white villi' groups based on VCE findings.
• Analysis of clinical and endoscopic features within these groups.

Main Results:

• 98 IL patients were included, with 58.2% showing white villi and 41.8% showing non-white villi.
• The white villi group had a significantly lower incidence of chylothorax (p=0.008).
• Lymphatic leakage was detected more frequently in the white villi group (31.6% vs. 12.2%, p=0.026).

Conclusions:

• VCE effectively visualizes small intestinal mucosal abnormalities in IL.
• IL exhibits specific VCE abnormalities beyond classical endoscopic findings.
• VCE findings, particularly white villi, can correlate with specific complications like lymphatic leakage.
