Introduction:
Lipedema is a relatively common, frequently misdiagnosed, chronic condition that is often treated using liposuction when conservative therapies fail. Techniques such as traditional tumescent liposuction (TTL), power-assisted liposuction (PAL), and water-jet-assisted liposuction (WAL) are popular surgical interventions, although it is unclear how these techniques compare. This meta-analysis aimed to assess the efficacy and safety of liposuction in patients with lipedema.
Methods:
Relevant English lipedema studies published in PubMed from January 2003 to April 2023 were identified. Ten articles with post-operative outcomes and complications data were included (2 TTL, 5 PAL, 1 WAL, and 2 articles used PAL and WAL). Results were summarized using descriptive statistics, and a randomized effects model was used to evaluate heterogeneity.
Results:
A total of 2542 procedures in 906 patients were included. Combined outcomes for all techniques significantly improved pain, bruising, edema, tension, pressure sensitivity, cosmetic impairment, and general impairment (all P < 0.00001). TTL, PAL, and WAL led to significant improvements in pain reduction P = 0.0005), bruising, swelling, pressure sensitivity, or cosmetic impairment (all P < 0.05). However, WAL more effectively reduced tension and general impairment (all P < 0.005), but heterogeneity for these outcomes was high. Overall complication rates were low for the studies that used TTL (1.5%), PAL (4.0%), WAL (0%), and both PAL and WAL (2.3%).
Conclusion:
Liposuction techniques, including TTL, PAL, and WAL, resulted in significant symptom improvement in patients with lipedema with a relatively low complication rate. WAL may potentially result in a more substantial reduction of tension and general impairment with fewer complications; however, only a single study performed this method of liposuction exclusively. To the best of our knowledge, this is the first meta-analysis investigating liposuction data in lipedema treatment.
