The billing of lipoedema treatment in Germany has come to be heterogeneous. This is due to the decision of the Federal Joint Committee ("Gemeinsamer Bundesausschuss", G-BA) to acknowledge lipoedema stage III as a treatment to be paid by the statutory health insurance funds ("Gesetzliche Krankenversicherung", GKV) until the completion of the trial study "LipLeg" at the end of 2024. Based on this decision, inpatient and outpatient surgical treatment of stage III lipoedema can be billed to the GKV, while the reimbursement of costs for surgical treatment of the other two stages remains a case-by-case decision of the GKV and is currently often rejected. Therefore, treatment costs are often paid by patients themselves. The question of the correct settlement of lipoedema treatment repeatedly arises in the context of legal disputes, which, in turn, repeatedly faces experts and courts with a major challenge. In the following article, the Task Force Lipoedema of the German Society for Plastic, Reconstructive and Aesthetic Surgery presents an overview of the various billing modalities and presents a proposal for the correct billing of lipoedema within the framework of the German medical fee schedule ("Gebührenordnung für Ärzte", GOÄ).

Objective The aim of this study is to assess the prevalence of HLA-DQ2 and HLA-DQ8 in women diagnosed with lipedema. Methods Leukocyte histocompatibility antigen (HLA) tests of 95 women diagnosed with lipedema were analyzed using non-probabilistic sampling for convenience. The prevalence of HLA-DQ2 and HLA-DQ8 was compared to the general population. Results The prevalence of HLA-DQ2+ was 47.4%, that of HLA-DQ8+ was 22.2%, the presence of any celiac disease associated HLA (HLA-DQ2+ or HLA-DQ8+) was 61.1%, both HLA (HLA-DQ2+ and HLA-DQ8+) was 7.4%, and the absence of celiac disease associated HLA was 39%. Compared to the general population, there was a significantly higher prevalence of HLA-DQ2, HLA-DQ8, any HLA, and both HLAs in lipedema patients. The mean weight of patients with HLA-DQ2+ was significantly lower than the overall study population, and their mean BMI significantly differed from the overall mean BMI. Conclusion Lipedema patients seeking medical assistance have a higher prevalence of HLA-DQ2 and HLA-DQ8. Considering the role of gluten in inflammation, further research is needed to establish if this association supports the benefit of gluten withdrawal from the diet in managing lipedema symptoms.

Background Posttraumatic lymphedema (PTL) is sparsely described in the literature. The aim of this study is to propose a comprehensive approach for prevention and treatment of PTL using lymphovenous anastomosis (LVA) and lymphatic vessels free flap, reporting our experience in the management of early-stage lymphedema. Methods A retrospective observational study was performed between October 2017 and July 2022. Functional assessment with magnetic resonance lymphangiography and indocyanine green lymphography was performed. Patients with lymphedema and functional lymphatic channels were included. Cases with limited soft tissue damage were proposed for LVA, and those with acute or prior soft tissue damage needing skin reconstruction were proposed for superficial circumflex iliac artery perforator lymphatic vessels free flap (SCIP-LV) to treat or prevent lymphedema. Primary and secondary outcomes were limb volume reduction and quality of life (QoL) improvement, respectively. Follow-up was at least 1 year. Results Twenty-eight patients were operated using this approach during the study period. LVA were performed in 12 patients; mean reduction of excess volume (REV) was 58.82% and the improvement in QoL was 49.25%. SCIP-LV was performed in seven patients with no flap failure; mean REV was 58.77% and the improvement QoL was 50.9%. Nine patients with acute injury in lymphatic critical areas were reconstructed with SCIP-LV as a preventive approach and no lymphedema was detected. Conclusion Our comprehensive approach provides an organized way to treat patients with PTL, or at risk of developing it, to have satisfactory results and improve their QoL.

INTRODUCTION: The aim was to reflect the established interdisciplinary aspects of general/abdominal and plastic surgery by means of a narrative review. Methods: (i) With specific references out of the medical literature and (ii) own clinical and perioperative as well as operating technical and tactical management experiences obtained in surgical daily practice, we present a choice of options for interdisciplinary cooperation that could be food of thought for other surgeons. CONTENT: - Decubital ulcers require pressure relieve, debridement and plastic surgery coverage, e.g., by a rotation flap plasty, V-Y flap or "tensor-fascia-lata" (TFL) flap depending on localization (sacral/gluteal defects, ischiadic tuber). - Coverage of soft tissue defects, e.g., after lymph node dissection, tumor lesions or disturbance of wound healing can be managed with fasciocutaneous or muscle flaps. - Bariatric surgery: Surgical interventions such as butt lift, tummy tuck should be explained and demonstrated in advance and performed commonly after reduction of the body weight. - Abdominoperineal rectum extirpation (APE): Holm's procedure with greater circumferential extent of resection at the mesorectum and the insertion site of the levator muscle at the anal sphicter muscle resulting in a substantial defect is covered by myocutaneous flap plasty. - Hernia surgery: Complicated/recurrent hernias or abdominal wall defect can be covered by flap plasty to achieve functional reconstruction, e.g., using innervated muscle. Thus, abdominal wall can respond better onto changes of pressure and tension. - Necrotising fasciitis: Even in case of suspicious fasciitis, an immediate radical debridement must be performed, followed by intensive care with calculated antibiotic treatment; after appropriate stabilization tissue defects can be covered by mesh graft of flap plasty. - Soft tissue tumor lesions cannot be resected with primary closure to achieve appropriate as intended R0 resection status by means of local radical resection all the time - plastic surgery expertise has to be included into interdisciplinary tumor concepts. - Liposuction/-filling: Liposuction can be used with aesthetic intention after bariatric surgery or for lipedema. Lipofilling is possible for reconstruction and for aesthetic purpose. - Reconstruction of lymphatic vessels: Lymphedema after tumor operations interrupting or blocking lymphatic drainage can be treated with microsurgical reconstructions (such as lympho-venous anastomoses, lympho-lymphatic anastomoses or free microvascular lymph node transfer). - Microsurgery: It is substantial part of modern reconstructive plastic surgery, i.e., surgery of peripheral nerves belongs to this field. For visceral surgery, it can become important for reconstruction of the recurrent laryngeal nerve. - Sternum osteomyelitis: Radical debridement (eventually, complete sternal resection) with conditioning of the wound by vacuum-assisted closure followed by plastic surgery coverage can prevent chronification, threatening mediastinitis, persisting infectious risk, long-term suffering or limited quality of life. SUMMARY: The presented selection of single topics can only be an excerpt of all the options for surgical cooperation in daily clinical and surgical practice. OUTLOOK: An interdisciplinary approach of abdominal and plastic surgery is characterized by a highly developed cooperation in common surgical interventions including various techniques and tactics highlighting the specifics of the two fields.

Lipedema is a chronic and progressive disease that may compromise lymphatic function. Although suction-assisted lipectomy (SAL) is considered a safe treatment for lipedema patients, the lymphatic repercussions of this surgical procedure are not fully understood. There is not enough evidence to support the role of SAL in lymphatic function treatment in lipedema. Here, we report a case of lymphatic drainage improvement after lipedema treatment with SAL. Tumescent SAL was performed in the deep subcutaneous layer, preserving the superficial and muscular lymphatic vessels. Pre- and postsurgical lymphoscintigraphy was equally documented under the Genoa protocol. A 34-year-old female patient presented with painful enlargement of the arms and lower limbs caused by lipedema. The patient had undergone conservative treatment with mild improvement in pain and heaviness. Lymphoscintigraphy showed slowed radiotracer progression on the left lower limb, collateral and tortuous lymphatic vessels on the right lower limb, and exuberant radiopharmaceutical concentration on the inguinal chain. Nine months after SAL was performed, the patient underwent another lymphoscintigraphy, which exhibited normalized radiopharmaceutical progression time and normal and symmetrical lymphatic vessel patterns. Collateral lymphatic paths and tortuosity vessels were no longer identified. Furthermore, the patient reported significant improvement in pain and the limb's appearance. Tumescent SAL is not only efficient and safe in treating lipedema, but may also be responsible for improvement in lymphatic drainage in lipedema patients. Additional prospective studies are fundamental to reinforce the current evidence and possibly yield predicting information about the tumescent liposuction eligibility in the improvement of lymphatic drainage.

Background Untreated lymphedema of an extremity leads to an increase in volume. The therapy of this condition can be conservative or surgical. Methods "Lymphological liposculpture" is a two-part procedure consisting of resection and conservative follow-up treatment to achieve curative volume adjustment of the extremities in secondary lymphedema. This treatment significantly reduces the need for complex decongestive therapy (CDT). From 2005 to 2020, 3,184 patients with secondary lymphedema after breast cancer and gynecological tumors were treated in our practice and clinic. "Lymphological liposculpture" was applied to 65 patients, and the data were recorded and evaluated by means of perometry and questionnaires. Results The alignment of the sick to the healthy side was achieved in all patients. In 58.42% ( n = 38), the CDT treatment could be completely stopped postoperatively; in another 33.82% ( n = 22) of the patients, a permanent reduction of the CDT was achieved. In 7.69% ( n = 5) patients, the postoperative CDT could not be reduced. A total of 92.30% ( n = 60) of the patients described a lasting significant improvement in their quality of life. Conclusion "Lymphological liposculpture" is a standardized curative sustainable procedure for secondary lymphedema for volume adjustment of the extremities and reduction of postoperative CDT with eminent improvement of the quality of life.

PURPOSE: Lipedema is a painful subcutaneous adipose tissue (SAT) disease involving disproportionate SAT accumulation in the lower extremities that is frequently misdiagnosed as obesity. We developed a semiautomatic segmentation pipeline to quantify the unique lower-extremity SAT quantity in lipedema from multislice chemical-shift-encoded (CSE) magnetic resonance imaging (MRI). APPROACH: Patients with lipedema (n=15) and controls (n=13) matched for age and body mass index (BMI) underwent CSE-MRI acquired from the thighs to ankles. Images were segmented to partition SAT and skeletal muscle with a semiautomated algorithm incorporating classical image processing techniques (thresholding, active contours, Boolean operations, and morphological operations). The Dice similarity coefficient (DSC) was computed for SAT and muscle automated versus ground truth segmentations in the calf and thigh. SAT and muscle volumes and the SAT-to-muscle volume ratio were calculated across slices for decades containing 10% of total slices per participant. The effect size was calculated, and Mann-Whitney U test applied to compare metrics in each decade between groups (significance: two-sided P<0.05). RESULTS: Mean DSC for SAT segmentations was 0.96 in the calf and 0.98 in the thigh, and for muscle was 0.97 in the calf and 0.97 in the thigh. In all decades, mean SAT volume was significantly elevated in participants with versus without lipedema (P<0.01), whereas muscle volume did not differ. Mean SAT-to-muscle volume ratio was significantly elevated (P<0.001) in all decades, where the greatest effect size for distinguishing lipedema was in the seventh decade approximately midthigh (r=0.76). CONCLUSIONS: The semiautomated segmentation of lower-extremity SAT and muscle from CSE-MRI could enable fast multislice analysis of SAT deposition throughout the legs relevant to distinguishing patients with lipedema from females with similar BMI but without SAT disease.

Lipohyperplasia dolorosa (LiDo), also known as lipedema, is a painful subcutaneous adipose tissue disorder. While the characteristic bilateral accumulation of adipocytes in extremities sparing hands and feet is investigated, an objective characterization of pain and the sensory system of LiDo patients is missing. Accordingly, progress to overcome the unsatisfying response to pain-therapeutics of patients of this widespread, lifelong, and severe disease is missing. We characterized the sensory detection profile of painful and non-painful stimuli in 20 non-obese LiDo patients and 20 waist-to-height-ratio matched controls using the clinically approved QST-protocol of the German Research Association on Neuropathic Pain (DFNS e.V.). Further, pain-reports and participants’-psychometry was assessed using the German Pain Questionnaire. LiDo patients showed no overt psychometric abnormalities. LiDo pain appeared as somatic rather than neuropathic or psychosomatic aversive. All QST measurements were normal with the selective exception of two: The pressure pain threshold (PPT) was strongly reduced and the vibration detection threshold (VDT) was strongly increased selectively at the affected thigh. In contrast, sensory profiles at the dorsum of the hand were normal. ROC-analysis of the combination of PPT and VDT of thigh versus hand shows high sensitivity and specificity, categorizing correctly 96.5% of the measured participants as LiDo patients or healthy controls, respectively. Thus, we propose to assess both, PPT and VDT, at the painful thigh and the pain-free hand as basis to develop a combined PVTH-score for differential diagnosis as a fast and convenient bedside test for the identification of non-obese LiDo patients.

Lipedema, lipohypertrophy and secondary lymphedema are three conditions characterized by disproportionate subcutaneous fat accumulation affecting the extremities. Despite the apparent similarities and differences among their phenotypes, a comprehensive histological and molecular comparison does not yet exist, supporting the idea that there is an insufficient understanding of the conditions and particularly of lipohypertrophy. In our study, we performed histological and molecular analysis in anatomically-, BMI- and gender-matched samples of lipedema, lipohypertrophy and secondary lymphedema versus healthy control patients. Hereby, we found a significantly increased epidermal thickness only in patients with lipedema and secondary lymphedema, while significant adipocyte hypertrophy was identified in both lipedema and lipohypertrophy. Interestingly, the assessment of lymphatic vessel morphology showed significantly decreased total area coverage in lipohypertrophy versus the other conditions, while VEGF-D expression was significantly decreased across all conditions. The analysis of junctional genes often associated with permeability indicated a distinct and higher expression only in secondary lymphedema. Finally, the evaluation of the immune cell infiltrate verified the increased CD4+ cell and macrophage infiltration in lymphedema and lipedema respectively, without depicting a distinct immune cell profile in lipohypertrophy. Our study describes the distinct histological and molecular characteristics of lipohypertrophy, clearly distinguishing it from its two most important differential diagnoses.

Introduction: Lipedema is a bilateral enlargement of the legs due to abnormal depositions of subcutaneous fat. Recent studies using lymphoscintigraphy documented that lipedema associates with lymphatic alterations. It is still not known, whether non-lipedema obesity also leads to similar lymphoscintigraphic changes within lower legs. Clinically, both, lipedema and obesity may progress to secondary lymphedema. The aim of the study was to evaluate lymphoscintigraphy of lower limbs in women with lipedema in comparison to overweight/obese women. Methods: 51 women (in the mean age of 43.3 ± 13.56) with the diagnosis of lipedema and 31 women (in the mean age of 44.7 ± 13.48) with overweight/obesity were enrolled into the study. Women in both study groups had no clinical signs of lymphedema. The groups were matched by mean volume of their legs, calculated using the formula for a truncated cone. Lymphoscintigraphy was evaluated in every women qualitatively. Body composition parameters were assessed using bioelectric impedance analysis (BIA). Results: Lymphoscintigraphic alterations within lower extremities were similar in both, lipedema and overweight/obese groups and were present in majority of women in both study groups. The most common lymphoscintigraphic alteration in both groups were additional lymphatic vessels (in the lipedema group observed in 76.5% of patients and in the overweight/obesity group – in 93.5%). Visualization of popliteal lymph nodes and dermal backflow were observed respectively in 33% and in 5.9% in the group with lipedema and in 45.2% and in 9.7% in the overweight/obesity group. There were significant relationships between severity of lymphoscintigraphic alterations and weight, lean body mass (LBM), total body water (TBW), volume of both legs and thigh circumference in the lipedema group. Such relationships were absent in the overweight/obesity group. Discussion: Our study indicates that lymphatic alterations are present before development to clinically visible secondary lymphedema in both conditions, lipedema and overweight/obesity. In majority of women from both study groups they indicate rather an overload of the lymphatic system than insufficiency. Lymphoscintigraphic alterations are similar in both groups, therefore, lymphoscintigraphy is not a diagnostic tool that might distinguish lipedema from overweight/obesity.

Lipoedema is an adipose tissue disorder almost exclusively affecting women. Evidence shows lipoedema is both poorly recognised and misdiagnosed which results in many women struggling to get a diagnosis and to gain access to specialist NHS services. This article aims to raise awareness of lipoedema and highlight the main role that community and primary care nurses can play in identifying this long-term condition earlier. It provides detail on the condition to help signpost, refer for diagnosis and initiate conservative management for those individuals with this challenging condition.

Abstract Lipedema is a wide-spread disease with painful accumulations of subcutaneous fat in legs and arms. Often obesity co-occurs. Many patients suffer from impairment in mobility and mental health. Obesity and mental health in turn can be positively influenced by physical activity. In this study we aimed to examine the interrelations between pain and physical activity on mental health in lipedema patients. In total, 511 female lipedema patients (age M = 40.16 ± 12.45 years, BMI M = 33.86 ± 7.80 kg/m 2 ) filled in questionnaires measuring pain (10-point scale), physical activity (7 Items; units per week), and mental health (PHQ-9; WHOQOL-BREF with subscales mental, physical, social, environmental, and overall health). Response surface analyses were calculated via R statistics. Explained variance was high for the model predicting depression severity (R 2 = .18, p < .001) and physical health (R 2 = .30, p < .001). Additive incongruence effects of pain and physical activity on depression severity, mental, physical, and overall health were found (all p < .001). In our study, physical activity and pain synergistically influenced physical, mental, and overall health. Pain did not only lead to low mental health but also interfered with the valuable potential of engaging in physical activity in lipedema patients.

Abstract Background and Aim: Chronic lower extremity edema has been associated with postural impairment, sacroiliac joint dysfunction (SIJD), and abnormal gait. Lymphedema and lipedema are important chronic lower extremity causes. This study aimed to detect the presence of SIJD and postural disorders in patients with lower extremity edema and the relationship between them. Methods: This is a comparative, prospective cohort study. Fifty-three patients with lower extremity edema and 53 healthy subjects were included in the study. Pain provocation tests were used to determine SIJD. Postural analysis was conducted with PostureScreen® Mobile 11.2 (PostureCo, Inc., Trinity, FL) software. The life quality of participants was determined by the Lymphedema Quality of Life (LYMQOL) scale. The functional status of the patients was determined by the Oswestry Disability Index and Lower Extremity Functional Scale. Results: SIJD (18.9%) was more common in the edema group. There was a positive correlation between volume differences, percentages, and the development of SIJD. We found deviations in the head, shoulder, and hip angulations in the edema group. Q angle and lateral shoulder angulation were significantly higher in patients with SIJD in the edema group. In the edema group, LYMQOL-leg total score was higher in patients with SIJD. Conclusion: Chronic lower extremity edema was found to be associated with postural deviations and SIJD. Besides edema control, postural disorders and SIJD should also be considered in these patients.

Expert representatives from 11 professional societies, as part of an autonomous work group, researched and developed appropriate use criteria (AUC) for lymphoscintigraphy in sentinel lymph node mapping and lymphedema. The complete findings and discussions of the work group, including example clinical scenarios, were published on October 8, 2022, and are available at https://www.snmmi.org/ClinicalPractice/ content.aspx?ItemNumber=42021. The complete AUC document includes clinical scenarios for scintigraphy in patients with breast, cutaneous, and other cancers, as well as for mapping lymphatic flow in lymphedema. Pediatric considerations are addressed. These AUC are intended to assist health care practitioners considering lymphoscintigraphy. Presented here is a brief overview of the AUC, including the rationale and methodology behind development of the document. For detailed findings of the work group, the reader should refer to the complete AUC document online.

Lymphangiogenesis is the mechanism by which the lymphatic system develops and expands new vessels facilitating fluid drainage and immune cell trafficking. Models to study lymphangiogenesis are necessary for a better understanding of the underlying mechanisms and to identify or test new therapeutic agents that target lymphangiogenesis. Across the lymphatic literature, multiple models have been developed to study lymphangiogenesis in vitro and in vivo. In vitro, lymphangiogenesis can be modeled with varying complexity, from monolayers to hydrogels to explants, with common metrics for characterizing proliferation, migration, and sprouting of lymphatic endothelial cells (LECs) and vessels. In comparison, in vivo models of lymphangiogenesis often use genetically modified zebrafish and mice, with in situ mouse models in the ear, cornea, hind leg, and tail. In vivo metrics, such as activation of LECs, number of new lymphatic vessels, and sprouting, mirror those most used in vitro, with the addition of lymphatic vessel hyperplasia and drainage. The impacts of lymphangiogenesis vary by context of tissue and pathology. Therapeutic targeting of lymphangiogenesis can have paradoxical effects depending on the pathology including lymphedema, cancer, organ transplant, and inflammation. In this review, we describe and compare lymphangiogenic outcomes and metrics between in vitro and in vivo studies, specifically reviewing only those publications in which both testing formats are used. We find that in vitro studies correlate well with in vivo in wound healing and development, but not in the reproductive tract or the complex tumor microenvironment. Considerations for improving in vitro models are to increase complexity with perfusable microfluidic devices, co-cultures with tissue-specific support cells, the inclusion of fluid flow, and pairing in vitro models of differing complexities. We believe that these changes would strengthen the correlation between in vitro and in vivo outcomes, giving more insight into lymphangiogenesis in healthy and pathological states.

OBJECTIVE: This study examines the role of MTHFR gene polymorphism (rs1801133) in women with lipedema (LIPPY) body composition parameters compared to a control group (CTRL). SUBJECTS AND METHODS: We carried out a study on a sample of 45 LIPPY and 50 women as a CTRL. Body composition parameters were examined by Dual-energy X-ray Absorptiometry (DXA). A genetic test was performed for the MTHFR polymorphism (rs1801133, 677C>T) using a saliva sample for LIPPY and CTRL groups. Mann-Whitney tests evaluated statistically significant differences between four groups (carriers and non-carriers of the MTHFR polymorphism for LIPPY and CTRL groups) on anthropometric/body composition parameters to identify patterns. RESULTS: LIPPY showed significantly higher (p<0.05) anthropometric parameters (weight, BMI, waist, abdominal, hip circumferences) and lower waist/hip ratio (p<0.05) compared to the CTRL group. The association between the polymorphism alleles related to the rs1801133 MTHFR gene and the body composition values LIPPY carriers (+) showed an increase in fat tissue of legs and fat region of legs percentage, arm’s fat mass (g), leg’s fat mass (g), and leg’s lean mass (g) (p<0.05) compared to CTRL (+). Lean/fat arms and lean/fat legs were lower (p<0.05) in LIPPY (+) than in CTRL (+). In the LIPPY (+), the risk of developing the lipedema disease was 2.85 times higher (OR=2.85; p<0.05; 95% confidence interval = 0.842-8.625) with respect to LIPPY (-) and CTRL. CONCLUSIONS: The presence or absence of MTHFR polymorphism offers predictive parameters that could better characterize women with lipedema based on the association between body composition and MTHFR presence.

As overweight and obesity rates have increased worldwide, the prevalence of metabolic disorders has also grown. Due to the lack of physiologically relevant adipose tissue platforms, research in adipose tissue biology has relied on animal models, leading to false conclusions on pathophysiological mechanisms and therapeutic efficacy. Despite the urgent need for an adipose tissue model, it is still extremely difficult to cultivate mature adipocytes and recapitulate multi-cellular interactions in adipose tissue in vitro. For this reason, adipose tissue modeling requires new technologies that allow better culture conditions for adipocytes and contain a complex network of microenvironments. Herein, we discuss recent technologies, including 3-dimensional (3D) adipocyte spheroids, biomaterial-based 3D culture, 3D bioprinting, and microphysiological systems, which may offer new opportunities to discover drugs targeting adipose tissue.

Obesity prevalence is rising globally, as are the number of chronic disorders connected with obesity, such as diabetes, non-alcoholic fatty liver disease, dyslipidemia, and hypertension. Bariatric surgery is also becoming more common, and it remains the most effective and long-term treatment for obesity. This study will assess the influence of Laparoscopic Sleeve Gastrectomy (LSG) on gut microbiota in people with obesity before and after surgery. The findings shed new light on the changes in gut microbiota in Saudi people with obesity following LSG. In conclusion, LSG may improve the metabolic profile, resulting in decreased fat mass and increased lean mass, as well as improving the microbial composition balance in the gastrointestinal tract, but this is still not equivalent to normal weight microbiology. A range of factors, including patient characteristics, geographic dispersion, type of operation, technique, and nutritional and caloric restriction, could explain differences in abundance between studies. This information could point to a novel and, most likely, tailored strategy in obesity therapy, which could eventually be incorporated into health evaluations and monitoring in preventive health care or clinical medicine.
