About this study

Official title: Multicentre, Controlled, Randomized, Investigator-blinded Clinical Trial on Efficacy and Safety of Surgical Therapy of Lipedema Compared to Complex Physical Decongestive Therapy Alone (LIPLEG)

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).

Read the detailed description

After being informed about the study and potential risks, all patients that gave written informed consent will undergo a run-in phase of up to seven months for edema elimination and maintenance of results using complex decongestive therapy (CDT). Afterwards, patients will be assigned to one of the two treatment groups via internet randomization, provided that all inclusion and exclusion criteria continue to be met. Randomization will be 2:1 (intervention: control). In the intervention arm, patients will receive liposuction treatment (number of surgeries at the discretion of the treating study physician: a maximum of four surgical procedures, with a minimum of 5 and a maximum of 7 weeks between each surgery) with, if necessary, concomitant CDT to maintain the surgical results as required by the patient.

The primary endpoint (regarding pain in the legs in stages I, II or III) will be assessed after an observation period of 12 months after final liposuction surgery. This is followed by a further follow-up period for 24 months to observe and document the further course.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LiposuctionProcedure or surgery

    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.

Study groups in NCT04272827
Study groupRoleWhat they receive
Intervention groupActive comparatorIn 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.
Receives: Procedure: Liposuction
Control groupOtherAfter 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.
Receives: Procedure: Liposuction

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

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

Secondary outcomes (16)
  1. Change in Pain Severity as Assessed by German Pain Questionnaire

    Change in severity according to von Korff et al. (1992) regarding pain in the legs (stage I, II or III). The severity is calculated based on the questions of the German Pain Questionnaire according to von Korff et al (1992). The assessment of the pain intensity as well as the impairment and information on the days of impairment are included in the calculation of the severity (classes 0 = no pain to 4 = high, pain-related impairment, strongly limiting).

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

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

    Change in health-related quality of life according to SF-36 questionnaire.

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

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

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

    Change in health-related quality of life according to WHOQOL-BREF questionnaire.

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

    Total impairment is measured by taking the mean of 7 numerical rating scales assessing the domains pain (spontaneous, pressure), swelling, hematoma, movement, cosmetic appearance and quality of life (0 (none) - 10 (always/very strong) points), see Schmeller et al. (2010).

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

  6. Altered Depression Tendency According to PHQ-9 Questionnaire

    Altered depression tendency according to PHQ-9 questionnaire (a clinically relevant improvement corresponds to ≥ 5 points reduction in PHQ-9 sum score).

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

  7. Altered Hematoma Tendency According to Schmeller et al. (2010)

    Hematoma ("Are you prone to bruising?") is measured by a numerical rating scale (0 (none) - 10 (always/very strong) points), see Schmeller et al. (2010).

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

  8. Changed Prevalence of Edema

    Changed prevalence of edema

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

  10. Change in Body Fat Percentage According to Wright et al. (1981)

    Change in body fat percentage, determined according to formula from Wright et al. (1981), collected by means of measuring tape at the following points:

    • abdominal circumference: measurement at the level of the navel. The tape measure is placed horizontally around the body
    • neck circumference: measurement below the larynx
    • body size
    • hip circumference: the widest part of the hip is measured.

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

  11. Change of Leg Circumference by Means of Measuring Tape

    Change of leg circumference of the left and right leg by means of measuring tape at five specified measuring points:
