From the Guidelines
The recommended treatment for intestinal lymphangioectasia is a diet low in long-chain triglycerides (LCT) and enriched in medium-chain triglycerides (MCT), with energy and protein intakes at least 30 kcal/kg actual body weight/day and 1.2 g/kg actual body weight/day, respectively. This approach is based on the most recent and highest quality study available, which suggests that a low-LCT and high-MCT diet can be beneficial for patients with protein-losing enteropathy due to intestinal lymphangiectasia 1.
Key Components of Treatment
- A diet with less than 5% of total energy intake from LCT and more than 20% of total energy intake from MCT
- Energy intake of at least 30 kcal/kg actual body weight/day
- Protein intake of at least 1.2 g/kg actual body weight/day
- Supplementation with fat-soluble vitamins (A, D, E, K) and calcium may be necessary
- Regular monitoring of serum proteins, lymphocyte counts, and nutritional parameters to assess treatment efficacy and adjust therapy accordingly
Additional Considerations
- In cases where dietary measures are not sufficient, medications such as octreotide or corticosteroids may be considered, although the evidence for these interventions is not as strong as for dietary modifications 1.
- Surgical intervention may be reserved for localized disease or specific anatomical abnormalities.
- Parenteral nutrition may be necessary in severe cases where oral nutrition is not possible or adequate.
The focus on dietary modifications as the cornerstone of treatment is supported by the consensus recommendation (89.1% agreement) in the ESPEN guideline on hospital nutrition 1, emphasizing the importance of a low-LCT and high-MCT diet in managing intestinal lymphangioectasia.
From the Research
Treatment Options for Intestinal Lymphangioectasia
The recommended treatment for intestinal lymphangioectasia can vary depending on the extent and location of the lesion. The following are some treatment options:
- Dietary therapy: A high-protein and low-fat diet with medium-chain triglycerides (MCT) supplementation can be effective in managing symptoms 2, 3.
- Intestinal resection: Surgical resection of the affected segment of the intestine can be considered for patients with focal lesions 4, 5.
- Radiologic embolization: Embolization of the affected lymphatic vessels can be an alternative to surgery for patients with focal lesions 4, 6.
- Pharmacological treatment: Several drugs, including octreotide and sirolimus, have been used to treat intestinal lymphangioectasia, although their effectiveness can vary depending on the extent and location of the lesion 4, 6.
Factors Influencing Treatment Choice
The choice of treatment depends on several factors, including:
- Extent of the lesion: Patients with focal lesions may be candidates for surgical resection or radiologic embolization, while those with diffuse lesions may require pharmacological treatment 4, 6.
- Location of the lesion: The location of the lesion can influence the choice of treatment, with lesions in the duodenum potentially being treated with surgical resection 5.
- Response to dietary therapy: Patients who do not respond to dietary therapy may require alternative treatments, such as pharmacological therapy or surgery 6, 3.
Effectiveness of Treatment Options
The effectiveness of different treatment options can vary, with some studies suggesting that:
