A systematic review on clinical and imaging criteria for liposuction candidacy in lower extremity lymphedema.

In 30 seconds

This systematic review examined clinical and imaging criteria used to select adults with lower-extremity lymphedema for liposuction. Seven eligible studies were included: five cohort studies and two systematic reviews with quantitative synthesis; findings were summarized narratively because of study heterogeneity. The review identified inadequate response to conservative care, ISL stage II–III disease, tissue composition, lymphedema cause, and ability to maintain lifelong compression as candidacy considerations. ISL stage II patients had significantly better volume reduction than stage III patients (P < .001); sustained reduction was reported up to 96 months with continuous compression.

Key findings

• ISL stage II patients had significantly better volume reduction outcomes than stage III patients (P < .001).
• Secondary lymphedema showed greater volume reduction than primary lymphedema at 24 months (101% vs 79%).
• Volume reduction was sustained up to 96 months, but required continuous compression therapy.
• MRI was the only imaging modality explicitly required as a formal candidacy criterion in an included study.

Why it matters

The review organizes the selection factors reported for liposuction in lower-extremity lymphedema, including disease stage, fibroadipose tissue features, response to conservative management, and capacity for ongoing compression. It also highlights gaps in evidence: candidacy criteria have not been tested in randomized trials, and quality of life and functional outcomes were inadequately assessed. These gaps matter when interpreting reported volume outcomes and considering patient selection.

What to keep in mind

No randomized controlled trials evaluated candidacy criteria. Only seven studies met inclusion criteria, findings were synthesized narratively because of heterogeneity, and quality of life and functional status were inadequately assessed.
