Liposuction is a procedure that involves the removal of fat from deposits beneath the skin using a hollow stainless steel tube with the assistance of a powerful vacuum. Liposuction can be accomplished either with the use of local or general anesthesia.
We plan to show the efficacy of liposuction as a treatment for lymphedema. Durability will be tested for equivalence, by comparing the 3-month and 12-month arm volumes.
- Number of Participants With Desired Response [ Time Frame: 3 months per participant ]We plan to show the efficacy of liposuction as a treatment for lymphedema. We will contrast the arm volume at 3 months with the baseline value using a paired t-test. Because the change in volume is likely to be proportional to the baseline value, the logarithm of the volumes will be used. With α = .05 and n = 34, we will have 80% power to detect an effect size of 0.5 (that is, a change of 0.5 standard deviations between the baseline and 3-month mean volumes). However since this is a pilot study with limited funding the study will initially open for 7 patients to assess safety and feasibility.
- Number of Participants With Durable Response [ Time Frame: 5 years ]Durability will be tested for equivalence, by comparing the 3-month and 12-month arm volumes. Five year follow-up is necessary to demonstrate the lasting effect of liposuction in reducing arm lymphedema.
- Number of Participants Who Develop an Infection [ Time Frame: 12 months per participant ]Measures to reduce skin infections will be implemented in this study but observance of infections will be an important study endpoint.
