NCT04272827

Brief Summary

The purpose of this study is to determine whether surgical treatment of lipedema (stage I, II or III) using liposuction significantly improves leg pain compared to the use of complex decongestive therapy (CDT).

Outcome Measures

Primary Outcomes (1)

  • Successful Pain Reduction After 12 Months (≥ 2 Points on a Numeric Rating Scale)

    The primary end point is the relevant reduction of the average pain of the last four weeks in the legs (≥ 2 points on a Numeric Rating Scale; German Pain Questionnaire) 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation.

    12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation)

Secondary Outcomes (16)

  • Change in Pain Severity as Assessed by German Pain Questionnaire

    12 months after completed liposuction treatment (intervention group) or after randomization (control group) compared with the time of randomisation)

  • Change in Health-Related Quality of Life According to SF-36 Questionnaire

    12 months after completed liposuction treatment (intervention group) or after randomization (control group) compared with the time of randomisation)

  • Change in Health-Related Quality of Life According to DLQI Questionnaire

    12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation)

  • Change in Health-Related Quality of Life According to WHOQOL-BREF Questionnaire

    12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation)

  • Change in Total Impairment According to Schmeller et al. (2010)

    12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation)

  • +11 more secondary outcomes

Study Arms (2)

Intervention group

ACTIVE COMPARATOR

In the intervention group, patients will receive liposuction treatment (number of surgeries at the discretion of the attending study physician: a maximum of 4 surgical procedures, with a minimum of 5 and a maximum of 7 weeks between each surgery) with concomitant complex decongestive therapy (CDT), if necessary, to maintain surgical outcomes as required by the patient.

Procedure: Liposuction

Control group

OTHER

After randomisation, the control group will be treated for 12 months with complex decongestive therapy (CDT) alone. After these 12 months, patients can opt for liposuction treatment if they continue to meet the inclusion and exclusion criteria.

Procedure: Liposuction

Interventions

LiposuctionPROCEDURE

Liposuction treatment will be performed according to the study protocol using the "wet technique" depending on the amount of fat to be removed, if necessary in several sessions.

Control groupIntervention group

Eligibility Criteria

Age18 Years+
Sexfemale(Gender-based eligibility)
Gender Eligibility DetailsLipedema is a symmetrical, congenital, excessive increase in fatty tissue on the legs, which occurs almost exclusively in women.
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Signed informed consent form
  • Female
  • Age ≥ 18 years
  • Confirmed lipedema of the legs in stage I, II or III
  • Average pain in the legs for the last four weeks ≥ 4 points on a numerical rating scale
  • Documentation of insufficient relief of symptoms by conservative measures
  • Willingness and ability to perform conservative measures according to the study protocol, during and, if necessary, after liposuction treatment
  • Full legal capacity

You may not qualify if:

  • Concurrent lipedema of the arms and legs, in which co-occurrence of lipedema in the arms affects the primary endpoint (i.e., average leg pain), at the discretion of the study investigator
  • Previous liposuctions
  • Diseases that may limit operability at the discretion of the study physician, e.g. cardiac diseases, coagulation disorders, metabolic diseases, infectious diseases (active), epilepsy; diseases requiring immunosuppression or anticoagulation with medication; allergies to medication accompanying surgery
  • Weight \>120.0 kg
  • Medical conditions that affect adequate complex decongestive therapy (CDT) at the discretion of the study physician, e.g. heart failure (volume stress), lack of physical ability to wear compression stockings (e.g. joint disease, neurological deficits).
  • Primary obesity without disproportion and without evidence of lipedema
  • Secondary obesity
  • Fat distribution disorders of other genesis (e.g. painless lipohypertrophy, benign symmetric lipomatoses or lipomatosis dolorosa)
  • Other edema-causing diseases (such as lymphedema, phlebedema, or myxedema)
  • Lack of willingness to ensure adequate contraception
  • Positive pregnancy test
  • Breastfeeding
  • Use of a lymphomat
  • Participation in other clinical studies
  • Purely cosmetic reasons for participation in the study
