From the Guidelines
The management of intestinal lymphangioectasia should focus on a diet low in long-chain triglycerides (LCT) and enriched in medium-chain triglycerides (MCT), with energy and protein intakes of 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 guideline recommendations, as outlined in the ESPEN guideline on hospital nutrition 1. The key components of this dietary management include:
- Restricting LCT to less than 5% of total energy intake
- Enriching the diet with MCT to more than 20% of total energy intake
- Ensuring adequate energy and protein intake to support overall nutritional needs
The rationale behind this approach is to reduce intestinal lymph flow and protein loss, which are critical in managing intestinal lymphangioectasia. By prioritizing a diet low in LCT and high in MCT, patients can help alleviate symptoms and improve their quality of life. It is essential to note that this management approach is based on a consensus recommendation with a high level of agreement (89.1%) among experts, as indicated in the ESPEN guideline 1.
In addition to dietary modifications, treating underlying causes and providing additional nutritional support may be necessary to manage intestinal lymphangioectasia effectively. However, the primary focus should be on implementing the recommended dietary changes, as outlined in the ESPEN guideline 1. Regular monitoring of serum proteins, lymphocyte counts, and nutritional parameters is crucial to assess treatment efficacy and adjust management accordingly.
From the Research
Management Approach for Intestinal Lymphangioectasia
The management of intestinal lymphangioectasia involves a combination of dietary modifications, medical therapy, and surgical interventions. The goal of treatment is to reduce the loss of lymphatic fluid, alleviate symptoms, and prevent complications.
- Dietary Modifications: A low-fat, high-protein diet with medium-chain triglycerides (MCT) supplementation is often recommended 2, 3, 4. MCTs are easily absorbed and can help reduce the loss of lymphatic fluid.
- Medical Therapy: Octreotide, a somatostatin analogue, has been used to treat intestinal lymphangioectasia, particularly in cases with refractory symptoms 5. However, its effectiveness in patients with extensive lymphangiectasis is limited 6. Sirolimus, an mTOR inhibitor, has shown promise in treating patients with extensive lymphangiectasis 6.
- Surgical Interventions: Surgical options, such as resection of isolated segments or peritoneal-venous shunts, may be considered in patients with focal abnormal lymphatic lesions 2. Therapeutic lymphatic embolization has also been used to treat patients with intestinal lymphangioectasia 6.
Treatment Outcomes
The outcome of treatment for intestinal lymphangioectasia varies depending on the severity of the disease and the effectiveness of the treatment approach. Studies have shown that:
- MCT diet can improve symptoms and reduce mortality in patients with primary intestinal lymphangiectasia 2.
- Octreotide therapy can alleviate symptoms and improve quality of life in some patients 5.
- Sirolimus can be an effective and safe treatment option for patients with extensive lymphangiectasis 6.
- Surgical interventions can be effective in treating patients with focal abnormal lymphatic lesions 2, 6.
