Lipedema is a chronic disorder of subcutaneous adipose tissue of unknown etiology not uncommon among post-puberty women. The disease has a negative impact on selfesteem, mobility, and quality of life. Lipedema is characterized by symmetrical, disfiguring hyperplastic adipose tissue combined with bruising and pain. Untreated lipedema fosters osteoarthritis, secondary lymphedema, limitedmobility, and psychosocial stigmatization. Treatment consists of conservative complex decongestive therapy and surgery by microcannular tumescent liposuction. Liposuction is the only available treatment capable to reduce the pathological adipose tissue durable and to prevent complications.

Lipedema is a chronic disabilitating disease affecting the subcutaneous adipose tissue of the extremities in females during or after puberty. The disease is characterized by bilateral swelling of legs and/or arms, bruising, and pain. In contrast to lymphedema, the most distal parts remain unaffected. In contrast to obesity, patients with lipedema have a lower risk of diabetes mellitus. The pathogenesis is not well understood. However, hormonal factors seem to play a vital role, as it is an exclusively female disorder. The recent advantages in understanding and treating lipedema are reviewed.

Lipedema is a painful disease of subcutaneous adipose tissue leading to bilateral increase of leg and/or arm volume, but sparing hands and feet. Although conservative treatment with complex decongestive therapy has been considered as the fundamental treatment, micro-cannular liposuction in tumescent anesthesia has become a surgical option. We report on 111 patients mostly with advanced lipedema treated by this technique in our center between 2007 and 2018. The median age of the patients was 44 years. Eighty percent of patients had at least one comorbidity. There was an association of longstanding and advanced disease to obesity and diseases of the metabolic syndrome-spectrum. The median total amount of lipoaspirate was 4,700 ml, with a range of 950-14,250 ml. The median reduction of limb circumference was 6 cm. The median pain level before treatment was 7.8 and 2.2 at the end of the treatment. An improvement of mobility could be achieved in all patients. Bruising was also reduced. Serious adverse events were observed in 1.2% of procedures, the infection rate was 0% and the bleeding rate was 0.3%. Liposuction is an effective treatment for painful lipedema. The procedure should be performed in specialized centers.

BACKGROUND: Lipedema is a rare female disorder with a characteristic distribution of adipose tissue hypertrophy on the extremities, with pain and bruising. In advanced stages, reduction of adipose tissue is the only available effective treatment. In elderly patients with advanced lipedema, correction of increased skin laxity has to be considered for an optimal outcome. METHODS: We report on a tailored combined approach to improve advanced lipedema in elderly females with multiple comorbidities. Microcannular laser-assisted liposuction of the upper legs and knees is performed under tumescent anesthesia. Medial thigh lift and partial lower abdominoplasty with minimal undermining are used to correct skin laxity and prevent intertrigo. Postsurgical care with nonelastic flat knitted compression garments and manual lymph drainage are used. RESULTS: We report on three women aged 55-77 years with advanced lipedema of the legs and multiple comorbidities. Using this step-by-step approach, a short operation time and early mobilization were possible. Minor adverse effects were temporary methemoglobinemia after tumescent anesthesia and postsurgical pain. No severe adverse effects were seen. Patient satisfaction was high. CONCLUSION: A tailored approach may be useful in advanced lipedema and is applicable even in elderly patients with multiple comorbidities.

Lipoedema is a rare painful disorder of the adipose tissue. It essentially affects females and is often misdiagnosed as lymphoedema or obesity. It is globally misdiagnosed or underdiagnosed, and the literature is lacking appropriate guidance to assist clinicians towards this diagnosis. However, the need to recognise this disorder as a unique entity has important implications to establish proper treatment and, therefore, its tremendous effect on patients. Early diagnosis and treatment can turn these patients' lives upside down. The aim of this review is to focus on the clinical guidance, differential diagnosis, and management strategies. In addition, other aspects of lipoedema, including epidemiology and pathogenesis, are also being discussed here. Lipoedema is distinct from obesity and distinct from lymphoedema, although it might progress to involve the venous and lymphatic system (venolipedema or lympholipedema or both). Late diagnosis can leave the patient debilitated. Management of lipoedema includes weight loss, control of oedema, complex decongestive physiotherapy, liposuction, and laser-assisted lipolysis. However; there are increasing reports on tumescent liposuction as the preferred surgical option with long-lasting results. The role of more randomised controlled studies to further explore the management of this clinical entity remains promising.

Methemoglobinemia is characterized by an increased level of methemoglobin (MetHb) in the peripheral blood. MetHb levels increase after tumescent anesthesia and need to be monitored. If a patient becomes symptomatic and/or the MetHb levels increase >10%, intravenous injection of an antidote is recommended. Toluidine blue is twice as effective as methylene blue in this respect.A 27-year-old woman with advanced lipedema underwent her third liposuction under tumescent anesthesia. After surgery, her MetHb levels increased and needed injection of toluidine blue. She developed an acute and painful edema after extravasation of some toluidine blue due to a bursting vein. This is the first report in the recent medical literature. Clinical presentation, course, and treatment are described.

Microcannular liposuction in tumescent anesthesia is the most effective treatment for painful lipedema. Tumescent anesthesia is an established and safe procedure in local analgesia when performed according to guidelines. Major adverse effects are rare. In patients with advanced lipedema, however, the commonly presented comorbidities bear additional risks.We report on post-surgical acute pulmonary edema after tumescent liposuction according to guidelines in a 52-year-old female patient with lipedema of the legs. We discuss in detail possible scenarios that might be involved in such emergency. In the present case the most likely was a retarded community acquired atypical pneumonia with aggravation of pre-existent comorbidities.A combined treatment with intravenous b-lactam antibiosis, positive pressure ventilation, and continuous venovenous hemodialysis and filtration resulted in complete remission in a couple of days. In conclusion, tumescent liposuction of advanced lipedema patients should only be performed in well-trained centers with sufficient infrastructure.

Lipedema is a painful, underdiagnosed adipose tissue disorder, characterized by symmetrical swelling of the extremities due to subcutaneous fat deposition in the buttocks, thighs, legs, and arms, sparing the most distal part of the extremities. Although etiology and pathogenesis of lipedema is unclear, possible role of hormonal and genetic factors have been proposed previously. Patients with lipedema suffer from pain, easy bruising, tenderness, and disfigurement. Pain is the leading symptom in lipedema. Since the pain is associated with depression and impaired quality of life, reduction of pain is the major therapeutic approach. Pain in lipedema is attributed to allodynia, exaggerated sympathetic signaling, and estrogens. Although the mechanism of pain in lipedema is uncertain, effective treatment of lipedema should provide a satisfactory pain reduction. Efficacy of the conservative treatment is a matter of debate. Microcannular tumescent liposuction is the most effective therapeutic option for lipedema. There is a large body of evidence that this procedure significantly reduces pain in patients with lipedema.

OBJECTIVE: Elephantiasis nostras is a rare complication in advanced lipo-lymphedema. While lipedema can be treated by liposuction and lymphedema by decongestive lymphatic therapy, elephantiasis nostras may need debulking surgery. METHODS: We present 2 cases of advanced lipo-lymphedema complicated by elephantiasis nostras. After tumescent microcannular laser-assisted liposuction both patients underwent a debulking surgery with a modification of Auchincloss-Kim's technique. Histologic examination of the tissue specimen was performed. RESULTS: The surgical treatment was well tolerated and primary healing was uneventful. After primary wound healing and ambulation of the patients, a delayed ulceration with lymphorrhea developed. It was treated by surgical necrectomy and vacuum-assisted closure leading to complete healing. Mobility of the leg was much improved. Histologic examination revealed massive ectatic lymphatic vessels nonreactive for podoplanin. CONCLUSIONS: Debulking surgery can be an adjuvant technique for elephantiasis nostras in advanced lipo-lymphedema. Although delayed postoperative wound healing problems were observed, necrectomy and vacuum-assisted closure achieved a complete healing. Histologic data suggest that the ectatic lymphatic vessels in these patients resemble finding in podoplanin knockout mice. The findings would explain the limitations of decongestive lymphatic therapy and tumescent liposuction in such patients and their predisposition to relapsing erysipelas.
