Intestinal lymphangiectasia and colonic polyps: surgical intervention

Area of Science:

• Pediatric Gastroenterology
• Surgical Gastroenterology
• Genetics and Rare Diseases

Background:

• Milroy's Disease is a rare genetic disorder characterized by lymphedema.
• Intestinal lymphangiectasia and exudative enteropathy (EE) can cause protein-losing enteropathy and hypoalbuminemia.
• Management of complex gastrointestinal disorders in children often requires a multidisciplinary approach.

Observation:

• A 36-month-old boy with Milroy's Disease, intestinal lymphangiectasia, and EE presented with colonic polyps.
• An adenomatous polyp was excised to manage EE and hypoalbuminemia (1.95 g/dl), leading to temporary stabilization.
• A subsequent exacerbation of EE at 50 months prompted surgical intervention.

Findings:

• A partial jejunal resection (40 cm) was performed for severe jejunal involvement.
• Post-surgery, 51Cr-tagged albumin studies showed no improvement in EE, but clinical status dramatically improved.
• The patient experienced sustained well-being and catch-up linear growth in the 10 months following surgery.

Implications:

• Surgical management, specifically jejunal resection, can be effective in improving clinical outcomes for exudative enteropathy, even without direct improvement in albumin loss markers.
• This case highlights the potential benefits of surgical intervention in refractory pediatric exudative enteropathy associated with rare genetic conditions.
• Further research into the mechanisms linking jejunal pathology to clinical improvement in EE is warranted.
