Implantation of Hydrophobic Tubes for Edema Fluid Drainage in Obstructive Lymphedema of Limbs - a Randomized Clinical Trial

Lymphedema is a chronic condition that affects the lymphatic system and accumulates protein-rich fluid in the interstitial spaces of the affected limb. The condition can occur after surgery, trauma, radiation therapy, or infection and can cause significant physical, functional, and psychosocial impairment. The chronic swelling and fibrosis of the affected limb can lead to difficulty with daily activities, decreased mobility, reduced quality of life, and increased susceptibility to infections (1).

Currently, the management of lymphedema involves both conservative and surgical approaches. Conservative treatment includes complex decongestive therapy, which combines manual lymphatic drainage, compression therapy, exercise, and skincare (reference here). While this approach can be effective, it requires long-term commitment and compliance from patients, which can be challenging (reference here). Surgical approaches, such as lymphaticovenular anastomosis or vascularized lymph node transfer, are reserved for patients with mild to severe or refractory lymphedema with moderate results (2).

Liposuction has been used as a treatment for lower limb lymphedema. The traditional treatment of lymphedema includes compression garments, exercise, and manual lymphatic drainage, but these methods are not very effective.

In advanced cases of lymphedema, where all main lymphatics vessels are obstructed, one possible solution may be to create artificial pathways for edema fluid to flow away from the obstructed regions. This can be achieved through the subcutaneous implantation of silicone tubes, a novel method for draining edema fluid in obstructive lymphedema of limbs (3).

In the lower limbs, the tubes are placed from the leg to the lumbar or hypogastric region, creating channels for fluid to flow away from the obstructed areas to the non-obstructed regions, where absorption can take place.
