Developmental phase

Primary outcomes Evaluate with the change in the number of times of cellulitis. In the LVA group, the number of cellulitis times during 24 weeks before the start of intervention and 24 weeks after the start of the intervention is compared. In the CDP therapy group, we compare the number of times of cellulitis in 24 weeks before the allocation date and 24 weeks after the allocation date. Cellulitis is defined as having inflammatory findings such as redness and heat sensation on the affected limbs and having a fever of 38.5 degrees or more.
Key secondary outcomes 1.Limb Circumference
Measure with six tapes of 20 cm above the knee, 10 cm above the knee, knee joint, 10 cm below the knee, ankle joint and foot sole, and calculate the rate of change based on the following formula. Measurements are blinded by doing a nurse or a physical therapist who is not involved in surgery or research protocol creation.
Change rate (%) = (Sum of surgical diameter after surgery - Sum of surrounding diameters before surgery) / Sum of peripheral diameter before surgery x 100

2.Pain and Discomfort
Visual Analogue Scale (VAS) are used

3.Tissue Hardness
Three kinds of urethane sponge with different hardness (Yawataneji K. K., Japan) are used, and the hardness of the skin and subcutaneous tissues of the affected limb is compared by palpation. Evaluate the distal inner and outer side of the lower leg, proximal inner and outer side of the lower thigh, inner side outer side of the thigh, inner side of the thigh and inner side and outer side of the thigh separately. Each sponge is numbered 2, 4, 6 according to the hardness, 2 points if it has the same hardness as 2, 1 point if it is softer than 2, 3 points if it is hardness between 2 and 4 Evaluate in seven stages of 1 to 7 and so on. This evaluation is blinded by doing a nurse or a physical therapist who is not involved in surgery and research protocol.

Using SF 36, we perform QOL evaluation before intervention and 6 months after intervention.
