INTRODUCTION: Nowadays, liposuction is the most frequently performed aesthetic surgery procedure in Western Countries. This technique has had rapid development since the 1970s, when it was experimented for the first time by A. and G. Fischer. It is currently widely used in clinical practice for many different situations in aesthetic, reconstructive and functional fields. MATERIALS AND METHODS: This review aims to describe the historical evolution of liposuction by analyzing the transformation of the method in function of the introduction of innovative ideas or instruments. We have also focused on reporting the major clinical applications of this surgical technique, applicable to almost the entire body surface. We finally analyzed the complications, both major and minor, associated with this surgical technique. RESULTS: Liposuction is mainly used to correct deep and superficial fat accumulations and remodel the body contour. It has become an essential complementary technique to enhance the aesthetic result of many other aesthetic procedures such as reduction mammoplasty, abdominoplasty, brachioplasty, thigh lift and post bariatric body contouring. However, it can be largely used for the treatment of innumerable pathologies in reconstructive surgery such as lipomas, lipedema, lipodystrophies, pneudogynecomastia and gynecomastia, macromastia e gigantomastia, lymphedema and many others. The complication rate is very low, especially when compared with conventional excisional surgery and the major, complications are generally associated with improper performance of the technique and poor patient management before and after surgery. CONCLUSION: Liposuction is a safe, simple and effective method of body contouring. It has enormous potential for its application in ablative and reconstructive surgery, far from the most common aesthetic processes with a very low complication rate.

Lipedema an often overlooked but treatable disease Lipedema is a painful disease that affects some women between puberty and menopause through a subcutaneous fat accumulation especially in the lower extremities. Patients suffer from pain and pressure tenderness. The larger fat accumulation, especially on the inside of the thighs and knees, causes walking difficulties. This can successfully be treated by liposuction with good long-term results in terms of pain reduction and prevention of osteoarthritis development in the knee and ankle joints.

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 self-esteem, 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, limited mobility, 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.

The present, revised guidelines on lipedema were developed under the auspices of and funded by the German Society of Phlebology (DGP). The recommendations are based on a systematic literature search and the consensus of eight medical societies and working groups. The guidelines contain recommendations with respect to diagnosis and management of lipedema. The diagnosis is established on the basis of medical history and clinical findings. Characteristically, there is a localized, symmetrical increase in subcutaneous adipose tissue in arms and legs that is in marked disproportion to the trunk. Other findings include edema, easy bruising, and increased tenderness. Further diagnostic tests are usually reserved for special cases that require additional workup. Lipedema is a chronic, progressive disorder marked by the individual variability and unpredictability of its clinical course. Treatment consists of four therapeutic mainstays that should be combined as necessary and address current clinical symptoms: complex physical therapy (manual lymphatic drainage, compression therapy, exercise therapy, and skin care), liposuction and plastic surgery, diet, and physical activity, as well as psychotherapy if necessary. Surgical procedures are indicated if - despite thorough conservative treatment - symptoms persist, or if there is progression of clinical findings and/or symptoms. If present, morbid obesity should be therapeutically addressed prior to liposuction.

Pain is an important criterion for diagnosing lipedema. This pain, however, has not been properly investigated or characterized in the literature, and in most cases, authors have settled for putting forward hypotheses. Comparison of these hypotheses with actual findings, if even available, it becomes obvious that many of these hypotheses cannot be correct. Hardly any of the tangible results seem to provide a solid basis for explaining lipedema-related pain. When examining lipedema-related pain reported in the pain literature, it becomes increasingly evident that dynamic mechanical allodynia, with Aß-fibers and probably tactile C (CT)-fibers, is Involved. It Is in principle possible to stimulate CT-fibers by manual lymphatic drainage (MLD), and this may explain the method's analgesic effects. Conversely however, this pain-relieving effect via CT-fibers seems to exclude the Involvement of small fiber neuropathy (SFN), and thus any direct nerve damage as the cause of pain in lipedema.

Lymphedema is a chronic, progressive, and common but often unrecognized condition. The diagnosis of lymphatic disease on clinical grounds alone remains a challenge. Without proper diagnosis, therapy is often delayed, allowing disease progression. There is a need for a practical diagnostic algorithm and its imaging technique to guide clinical decision-making. The aim of this topical review is to provide a practical approach for assessing patients with suspected lymphedema and to give a critical appraisal of currently available imaging modalities that are applied in clinical practice to diagnose and map lymphatic disease.

Das Lipödem ist eine sehr komplexe, unvermutet häufig anzutreffende Erkrankung des Fettsystems der Extremitäten. Es handelt sich hier um ein lymphologisches Krankheitsbild, wobei besonders das Baufett betroffen ist. Nur in wenigen Fällen ist es auch mit metabolischen Symptomen assoziiert. Das Lipödem ist eine Sonderform der Adipositas, die weder in der Medizin noch in der Bevölkerung als bewegungs- und diätresistent wahrgenommen wird. Die betroffenen Patienten sind in ihrem seelischen Gleichgewicht äußerst betroffen. Aufgrund unserer anatomischen Untersuchungen kann man durchaus von einer ernsthaften, progressiven Erkrankung des subkutanen Fettgewebes und der benachbarten, assoziierten Strukturen sprechen. Es ist nicht nur die Klinik, sondern auch die duplexsonographische Evaluierung und impedanzanalytische Exploration sind zur Diagnosefindung und zur postoperativen Verlaufskontrolle notwendig. Auch bestätigt ein besonderes Verhalten der Stammzellen den Pathomechanismus. Durch Ausdünnung der Dermis und Verlust der elastischen Fasern sind dermatologische Problemstellungen wie Trockenheit, Infektneigung, Vulnerabilität und Neigung zu Ekchymosen erklärbar. Hier dürfte v. a. die Funktion des dermalen Fettes beeinträchtigt sein. Aus unseren Beobachtungen geht hervor, dass insbesondere die frühzeitige operative Therapie mittels Liposuktion einen nachhaltigen Wert für Patienten im Frühstadium hat und den Patienten eine deutliche Verbesserung der Lebensqualität bringt.

Introduction Lipedema is a chronic, progressive condition that can result in considerable disability. In 2011, the Dutch Society of Dermatology and Venereology organized a task force to create guidelines on lipedema, using the International Classification of Functioning, Disability and Health of the World Health Organization. Guideline development Clinical questions on significant issues in lipedema care were proposed, involving (1) making the diagnosis of lipedema; (2) clinimetric measurements for early detection and adequate follow-up; and (3) treatment. A systematic review of literature published up to June 2013 was conducted. Based on available evidence and experience of the task force, answers were formed and recommendations were stated. The guidelines define criteria to make a medical diagnosis of lipedema, a minimum data set of (repeated) clinical measurements that should be used to ensure early detection and an individually outlined follow-up plan, pillars on which conservative treatment should be based and recommendations on surgical treatment options. Conclusions Little consistent information concerning either diagnostics or therapy can be found in the literature. It is likely that lipedema is frequently misdiagnosed or wrongly diagnosed as only an aesthetic problem and therefore under- or mis-treated. Treatment is divided into conservative and chirurgic treatment. The only available technique to correct the abnormal adipose tissue is surgery. Recommendations To ensure early detection and an individually outlined follow-up, the committee advises the use of a minimum data set of (repeated) measurements of waist circumference, circumference of involved limbs, body mass index and scoring of the level of daily practice and psychosocial distress. Promotion of a healthy lifestyle with individually adjusted weight control measures, graded activity training programs, edema reduction, and other supportive measures are pillars of conservative therapy. Tumescent liposuction is the treatment of choice for patients with a suitable health profile and/or inadequate response to conservative and supportive measures.

Lower extremity edema is extremely common among patients seen across multiple specialties. The differential diagnosis is broad and ranges from simple dependent edema to more complex conditions such as chronic venous disease and lymphedema. Several key features from the history and physical exam can assist with the diagnosis. Imaging is rarely necessary at the initial visit unless venous thromboembolism is suspected. Treatment is specific to the etiology of the edema, but compression stockings, elevation, exercise, and weight loss remain the cornerstone in most cases.

BACKGROUND: People with lipedema or Dercum's disease (DD) can have a similar distribution of excess painful nodular subcutaneous adipose tissue (SAT), making them difficult to differentiate. METHODS: Case series of 94 patients with DD, 160 with lipedema and 18 with both diagnoses (Lip+DD) from a single clinic in an academic medical center to improve identification and differentiation of these disorders by comparison of clinical findings, prevalence of type 2 diabetes (DM2), hypermobility by the Beighton score and assessment of a marker of inflammation, Total complement activity (CH50). RESULTS: Differences between groups were by Student's t-test with α of 0.05. The Lipedema Group had significantly greater weight, body mass index (BMI), gynoid distributed nodular SAT and fibrotic and heavy tissue than the DD Group. Hypermobility was significantly higher in the Lipedema (58±0.5%) than DD Group (23±0.4%; P<0.0001). DM2 was significantly greater in the DD (16±0.2%; P=0.0007) than the Lipedema Group (6±0.2%). Average pain by an analog scale was significantly higher in the DD (6±2.5%) than the Lipedema Group (4±2.1%; P<0.0001). Fatigue and swelling were common in both groups. Easy bruising was more common in the Lipedema Group, whereas abdominal pain, shortness of breath, fibromyalgia, migraines and lipomas were more prevalent in the DD Group. The percentage of patients with elevated CH50 was significantly positive in both groups. CONCLUSIONS: The significantly lower prevalence of DM2 in people with lipedema compared with DD may be due to the greater amount of gynoid fat known to be protective against metabolic disorders. The high percentage of hypermobility in lipedema patients indicates that it may be a comorbid condition. The location of fat, high average daily pain, presence of lipomas and comorbid painful disorders in DD patients may help differentiate from lipedema.

Das Lipödem ist gekennzeichnet durch eine dispropor tionale Vermehrung des subkutanen Fettgewebes an Hüf ten, Beinen und Armen. Von der asymptomatischen Lipo hypertrophie unterscheidet es sich durch das Vorhandensein der typischen Symptome (Spontan und Berührungsempfindlichkeit, Ödeme). Auch wenn die Pathogenese des Lipödems immer noch weitgehend unbe kannt ist, deutet vieles darauf hin, dass neben hormonel len Faktoren entzündliche Prozesse eine wesentliche Rolle spielen. Dabei ist nicht geklärt, ob und in welcher Weise diese selbst ursächlich für das Auftreten des Lipödems sind oder Folge anderer körperlicher Veränderungen wie Adipositas oder hormoneller Dysbalancen. Der Circulus vitiosus aus Adipositas, die bei über der Hälfte der Patientinnen vorliegt, und der sich hierdurch entwickelnden Hyperinsulinämie bewirkt nicht nur eine weitere Fettgewebszunahme, sondern wirkt über die Zyto kine des viszeralen Fettgewebes auch proinflammatorisch und ödemfördernd,

EXECUTIVE SUMMARY Lipedema is a chronic condition that occurs almost exclusively in women and manifests as symmetrical buildup of painful fat and swelling in the limbs, sparing the hands and feet. A critical issue is the poorly understood disease biology, which for diagnosed patients results in limited treatment options that, at best, ameliorate the symptoms of lipedema. Individuals who suffer from the disease are further impacted by the absence of diagnostic tools, the lack of public and medical awareness of lipedema, and the stigma associated with weight gain. As a result, the true number of women with lipedema, or its epidemiology, is unknown. Braving these challenges is an active, numerous, and engaged patient community eager to participate in lipedema research. Supported by equally devoted caregivers and researchers, the lipedema field presents an immense opportunity for scientific and medical advancements. To capitalize on this potential, the Lipedema Foundation and the Milken Institute’s Center for Strategic Philanthropy convened leading stakeholders to discuss the current state of lipedema science and identify the key philanthropic research opportunities to advance the field. Little is known about how and why lipedema develops in a patient. Although the disease is reported to occur during puberty and other periods of hormonal changes, why this happens is not understood. The painful fat and swelling in some patients can be so debilitating that their mobility is impaired; yet what drives these symptoms is unknown. Psychosocial issues are also prevalent in women with lipedema, contributing to health burden and complexity of disease management. Furthermore, many patients develop the disease alongside obesity; however, diet, exercise, and weight loss surgery have limited effect on lipedema fat. Although the lack of disease biology is staggering, philanthropic investments in research can leverage the desire of patients to participate in studies to improve their and the entire field’s understanding of lipedema. The convergence of multiple scientific topics around lipedema indicates that addressing these gaps in research will also improve the understanding of hormone, pain and edema, mental health, and metabolic biology. There are no diagnostic tools or tests for lipedema. Diagnosis of lipedema involves a clinical assessment and discussion of the individual’s medical history, a process that is difficult to scale within the current healthcare system. The absence of diagnostic tools to streamline or confirm a clinical diagnosis is a key unmet need, which if addressed by philanthropy, has the potential to dramatically change the trajectory of the disease. Investing in research efforts to advance novel imaging technologies to diagnose lipedema is a promising research avenue that would simultaneously benefit individuals who suffer from the disease and healthcare providers unfamiliar with the condition. The public and medical community are not aware of lipedema. Lipedema was initially described in 1940, yet little knowledge about the disease has permeated the general public, with a concomitant lack of mention in the educational curriculum of medical trainees. Addressing this challenge will require philanthropic efforts to define the disease from a basic, clinical, and diagnostic perspective. A key philanthropic opportunity is support for a lipedema patient registry linked to a tissue biorepository. This effort has the potential to generate and support the needed disease research, while engaging patients as partners in understanding the science of lipedema.
