Brief Summary:
Although there is no doubt about the need for compression therapy in lymphoedema, it is not investigated in much detail how much pressure is needed to get optimum volume reduction. New research suggests that there is obviously an upper pressure limit beyond further increase of pressure seems contra productive. This upper limit is around 30-40 mm Hg of initial pressure exerted by inelastic bandages on the upper and around 50-60 mm Hg on the lower extremity. This study is designed to investigate the effect of pressure on %volume reduction of leg lymphoedema with 2 bandages which are very comparable in product properties (slippage, stiffness, etc.), but differ in their pressure exerted to the limb.

Detailed Description:

Lymphoedema is a chronic swelling caused by the regional accumulation of protein-rich fluid in tissues due to a compromised lymphatic system. This may present as primary lymphoedema, defined as congenital abnormality of lymphatic vessels or secondary lymphoedema, acquired from various insults to the lymphatic system, such as malignancy, trauma, surgery or irradiation. It is most frequently seen after lymph node dissection, surgery or radiation therapy during cancer treatment, most notably breast cancer. In the United Kingdom a large prevalence study was undertaken by Moffatt et al and a rate of 1.33 per 1000 population was identified. In general, the prevalence increases with age and is higher in women than in men. One function of the lymphatic system is to remove fluid from the interstitial tissues and return it to the venous circulation. compression therapy is the cornerstone in the treatment of lymphoedema

Much of evidence how compression works is based on research in venous disease, which has been extrapolated to lymphoedema. Hence, compression bandaging systems available in the market are used for the treatment of venous disease and at the same time lymphoedema.

This upper limit is around 30-40 mm Hg of initial pressure exerted by inelastic bandages on the upper and around 50-60 mm Hg on the lower extremity. This is also stated in the International Lymphoedema Framework position document "Compression Therapy: A position document on compression bandaging".

100 subjects with leg lymphoedema will be enrolled into the study. The duration of study will be one week for each participant. All participants will receive compression therapy with 3M Coban 2 and 3M Coban 2 Lite respectively according to the randomisation list. The goal of the present study is to gain information on %volume reduction of lymphoedematous legs in relation to pressure.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. volume decrease in relation to pressure application of two types of bandages [ Time Frame: 1 week, 2 bandages changes ]

    At each of the 8 visits the supine and standing pressure under the bandage is measured with a Picopress device at the B1, C and F positions. The patient will receive new bandaging twice a week. At those visits the volume is determined and a second pressure measurement is conducted 2 hours after bandage application. For safety assessment all adverse events will be documented.

    The total number of bandage changes could increase if bandage changes are required more often. On these occasions all measurements, which are required on a regular bandage change day, will be performed.



Secondary Outcome Measures :
  1. pressure drop profiles under 2 bandage types [ Time Frame: 1 week ]

    At each of the 8 visits the supine and standing pressure under the bandage is measured with a Picopress device at the B1, C and F positions. The patient will receive new bandaging twice a week. At those visits the volume is determined and a second pressure measurement is conducted 2 hours after bandage application. For safety assessment all adverse events will be documented.

    The total number of bandage changes could increase if bandage changes are required more often. On these occasions all measurements, which are required on a regular bandage change day, will be performed.
