Objective: Vascularized lymph node transfer (VLNT) has become an important surgical technique in the treatment of lymphedema. Considering the different available regions available for flap harvest, we aimed to analyze different donor sites for VLNT with respect to donor site morbidity, impact on limb volume, and patient-reported outcome measurements (PROMs)., Methods: A single-center prospective study of all patients undergoing VLNT at the Department of Plastic Surgery and Hand Surgery of the University Hospital Zurich between September 2016 and 2023 was conducted. Lymph nodes were harvested either from the omentum (gastroepiploic [GE]-VLNT), the lateral thoracic wall (LTW), or the superficial inguinal region (SI-VLNT). Volume measurements and PROMs were assessed preoperatively and at different postoperative intervals., Results: Overall, 70 patients with upper limb lymphedema (21%) or lower limb lymphedema (79%) with different lymphedema stages were included. There were 49 patients who underwent GE-VLNT, followed by LTW-VLNT (n = 16) and SI-VLNT (n = 5). Lymph node harvest from the SI was associated with a significantly higher frequency of seroma development. The average percentage volume loss related in comparison to the preoperative volume of the affected limb was 9% after GE-VLNT, 10% after LTW-VLNT, and 5% after SI-VLNT without a significant difference between the groups. PROMs revealed significant improvements for physical functioning, symptoms and psychological well-being, with no differences between the VLNT techniques., Conclusions: VLNT leads to a significant improvement of quality of life and can decrease limb volume effectively, regardless of the selection of donor site. GE-VLNT has become our flap of choice owing to its low donor site morbidity and its properties that allow a double transplantation while avoiding a second donor site., (Copyright © 2024 The Author(s).

Introduction: Postoperative chronic lymphocele and lymphedema represent severe burdens for soft tissue sarcoma patients who are already physically handicapped after an extensive surgery and a long recovery time. Incidences are high in the upper medial thigh. We have shifted our focus to lymphedema and lymphocele risk reduction with immediate lymphovenous anastomosis (LVA) after sarcoma resection., Methods: We performed immediate lymphatic reconstruction in 11 patients after soft tissue sarcoma resection in the upper medial thigh. The postoperative course was followed up closely, and postoperative occurrence of lymphocele and lymphedema was clinically assessed. A literature search outlining the latest clinical data, current treatment strategy landscape, and their application into clinical practice was added to the investigation., Results: A total of 19 LVA and 2 lympho-lymphatic anastomoses were performed in 11 patients immediately after tumor resection in an end-to-end manner. We found a postoperative lymphedema rate of 36% and a postoperative lymphocele rate of 27%. Mean follow-up time was 17 months. Average tumor volume was 749 cc. Our literature search yielded 27 articles reporting on immediate LVA in cancer patients. Incidences of secondary lymphedema after LVA for lymphedema prevention vary between 0% and 31.1%. Lymphocele prevention with LVA is poorly studied in sarcoma patients., Conclusion: Immediate lymphatic reconstruction improved the overall postoperative course of our patients. The current literature does not serve with high-quality studies about primary LVA preventing lymphedema and lymphocele formation. We conclude that this technique should be seen as an additional concept to achieve overall better postoperative outcomes in these challenging surgical settings. We strongly recommend to either anastomose or ligate severed lymphatics under the microscope primarily after sarcoma resection in the upper medial thigh area., Competing Interests: Nicole Lindenblatt acts as scientific advisor and consultant for Medical Microinstruments.

Patients with upper limb lymphedema and lower limb lymphedema experience a wide range of physical and psychological symptoms that affect quality of life. The benefits of lymphatic reconstructive surgery for patients with lymphedema are undisputed. However, recording volume reduction alone may be insufficient with regard to postoperative outcome because measurements are often inadequate, depend on many factors, and do not reflect improvement in quality of life., Methods: We conducted a prospective single center study patients receiving lymphatic reconstructive surgery. Patients received volume measurements preoperatively and at standardized postoperative intervals. To evaluate patient-reported outcomes, patients completed the following questionnaires: LYMPH-Q Upper Extremity Module, quickDASH, SF 36, Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema, and Lower Extremity Functional Scale at the aforementioned intervals., Results: We included 55 patients with upper limb lymphedema (24%) and lower limb lymphedema (73%) of lymphedema grades I-III. Patients received lymphovenous anastomosis only (23%), free vascularized lymph node transfer (35%) or a combination of both (42%). Analysis of patient-reported outcome measurements revealed improvements with respect to a broad range of complaints, particularly physical function, symptoms, and psychological well-being. There was no correlation between the extent of volume reduction and improvement in quality of life (Pearson correlation coefficient below ±0.7; P > 0.05)., Conclusions: Based on a broad range of outcome measurements, we observed an improved quality of life in almost all patients, even in those without measurable volume loss of the extremity operated on, which emphasizes the need for a standardized use of patient-reported outcome measures to evaluate the benefits of lymphatic reconstructive surgery., Competing Interests: Nicole Lindenblatt acts as a scientific advisor and symposium speaker for Medical Microinstruments (MMI).

In recent years surgical robotic systems which were specifically developed for microsurgery have expanded the application of robotic-assisted surgery to plastic reconstructive surgery. Currently, there are two microsurgical robotic systems available for reconstructive plastic surgery. Both systems feature tremor reduction and motion scaling technologies, which are intended to optimize the surgeon's precision and dexterity. In the Department of Plastic Surgery and Hand Surgery at the University Hospital Zurich, the Symani Surgical System® has already been used for many microsurgical and supermicrosurgical operations, including autologous breast reconstruction, nerve transfer and, in particular, reconstructive lymphatic surgery. Despite special technical challenges, such as a lack of haptic feedback, the advantages outweigh the disadvantages for an appropriately trained and skilled microsurgeon, including smaller surgical access incisions for anatomically deep structures and an improvement in surgical precision., (© 2023.

Introduction: Circumferential deep burns carry a high risk for a burn induced compartment syndrome. It was recently shown that an enzymatic bromelain-based debridement with Nexobrid® is a safe and efficient procedure to release pressure in deep circumferential extremity burns reducing the need for surgical escharotomy. We therefore herein aimed to analyze the conceptual relation between Nexobrid® and surgical escharotomy., Patients and Methods: We conducted a retrospective study on all patients with circumferential deep partial-thickness or full-thickness burns requiring immediate escharotomy that was either performed by surgical incision or Nexobrid®. Medical records of 792 patients that were treated at the burn center of the University Hospital Zurich between 2016 and 2021 were analyzed., Results: Overall, 62 patients with circumferential deep partial-thickness or full-thickness burns who received preventive decompression either by Nexobrid® (N = 29) or surgical escharotomy (N = 33), were included. Whilst distribution of age, sex, BMI and type of injury showed no difference between the groups, the ABSI score, TBSA, percentage of third degree burns and mortality were significantly higher in patients who received a surgical escharotomy., Conclusion: While the use of Nexobrid® to prevent burn induced compartment syndrome has steadily increased, surgical escharotomies were predominantly performed in severely burned patients with a high degree of full-thickness burns. Thus, higher mortality in this patient group needs to be considered with caution and is mainly attributed to the higher TBSA. Although evidence is lacking for the use of Nexobrid® for larger body areas exceeding 15%, escharotomy is also the more reliable and faster approach in such critically burned patients., Competing Interests: Declaration of Competing Interest Nicole Lindenblatt acts as a symposium speaker and clinical advisor for Medical Microinstruments (MMI).

Background: In lymphatic reconstructive surgery, visualization of lymph vessels is of paramount importance. Indocyanine green (ICG) lymphography is the current gold standard in preoperative lymphatic imaging. However, visualization of lymph vessels is often limited by an overlying dermal backflow of ICG, becoming particularly prominent in advanced lymphedema stages. Multispectral optoacoustic tomography (MSOT) has recently been introduced as a promising noninvasive tool for lymphatic imaging. Methods and Results: A single-center proof-of-concept study with a prospective observational design was conducted at the Department of Plastic Surgery and Hand Surgery of the University Hospital Zurich. Between February 2021 and August 2021, seven patients with different grades of lymphedema were analyzed by the MSOT Acuity system before undergoing lymphovenous anastomosis (LVA). Conventional ICG lymphography served as comparison. MSOT succeeded to accurately depict blood and lymphatic vessels at different locations in six patients, including areas of dermal backflow. The MSOT signal of lymph vessels further correlated well with their macroscopic appearance. Conclusion: We could successfully visualize lymphatic vessels in patients with lymphedema by MSOT and establish the new method for preoperative mapping and selection of incision sites for LVA. Regardless of dermal backflow patterns, MSOT proved to be a valuable approach for identifying and clearly discerning between lymphatic and blood vessels.

Robotic systems have recently been introduced into micro- and supermicrosurgery showing potential benefits for reconstructive surgery. After showing the feasibility and safety of using the Symani Surgical System® for lymphatic microsurgical procedures in humans, we present the results of the first twenty-two patients operated with the robot. The main goal of the study was to determine the learning curve using the Symani Surgical System® . In addition, we aimed at exploring the potential of robot-assisted anastomosis for lymphatic, free flap, and nerve reconstruction and defining the advantages and drawbacks of implementing the system into our daily routine. The operating times were compared between robotic-assisted and hand-sewn anastomoses. Moreover, outcomes and complications were recorded. In this first patient series, anastomotic times were significantly faster with the hand-sewn technique (14.1±4.3 min) when compared with the robot-assisted technique (25.3±12.3 min; p<0.01). However, the learning curve was very steep, and the time needed to perform the anastomosis has been consistently decreasing over time to the point where in the last operations, the times to perform particularly lympho-venous anastomoses were comparable between the two groups. Based on our experience up to date, robot-assisted surgery shows a promising potential in opening up new frontiers in reconstructive microsurgery, e.g., the reliable performance of anastomoses on even smaller blood and lymphatic vessels or on structures deeper within the body cavities, e.g., the thoracic duct., Competing Interests: Nicole Lindenblatt acts as a symposium speaker and clinical advisor for Medical Microinstruments.

Objective: Upper extremity lymphedema is a burdensome disease with significant effects on quality of life, underscoring the importance of quality of life measures for this patient population. Only recently, the LYMPH-Q Upper Extremity Module, a new patient-reported outcome measure, was developed. The aim of the present study was to translate the LYMPH-Q Upper Extremity Module from English to German and perform a comprehensive validation., Methods: Translation was performed in accordance with the International Society for Pharmacoeconomics and Outcomes Research best practice guidelines. To validate the German LYMPH-Q, a multicenter study was conducted. Internal consistency was determined using Cronbach's α. Reliability was assessed using the intraclass correlation coefficient. To analyze construct validity, the Pearson correlation coefficient between the LYMPH-Q, quickDASH (disabilities of the arm, shoulder, and hand), and short-form 36-item health survey was calculated. Responsiveness was assessed by comparing the pre- and postoperative LYMPH-Q scores in five patients who had undergone lymphatic reconstructive surgery., Results: Validation was performed using a cohort of 65 patients. The internal consistency of the different domains was good to excellent (α, 0.87-0.97). The intraclass correlation coefficient ranged from 0.74 to 0.92. The domains of the LYMPH-Q correlated significantly with the corresponding domains of the short-form 36-item health survey and quickDASH. Construct validity was good, with 8 of 10 hypotheses confirmed. Significant improvements in function (46.4 ± 13.3 vs 77.8 ± 11.5; P = .03), symptoms (42.0 ± 10.7 vs 70.6 ± 11.6; P = .02), and psychological well-being (40.4 ± 14.6 vs 78.0 ± 17.3; P = .03) were observed after lymphatic reconstructive surgery., Conclusions: The German version of the LYMPH-Q Upper Extremity Module was shown to be conceptually equivalent to the original English version. It was shown to be a reliable and valid patient-reported outcome measure to assess the physical and psychological impairments in patients with upper extremity lymphedema., (Copyright © 2022 Society for Vascular Surgery.

Invasive fungal infections from Saksenaea , a fungus belonging to the Mucorales, have been rarely reported in central European climate zones. This study aims to raise awareness of invasive cutaneous infections with Saksenaea species. The first case of a cutaneous infection was diagnosed in Switzerland in an immunocompetent 79-year-old patient. A minor skin trauma of her left lower leg led to a fulminant infection causing necrosis and extensive loss of tissue. The combination of surgical debridement and administration of antifungal agents averted a prolonged course with a possible worse outcome. A pedicled hemisoleus muscle flap was used to reconstruct the defect and treatment was continued for 63 days., Methods: A systematic review in accordance with the Preferred Reporting Items for Systematic review and Meta-Analysis guidelines was conducted to identify all European cases of infection with Saksenaea species in immunocompetent hosts. The epidemiology, clinical presentation, microbiological diagnosis, and management of cases reported in Europe were summarized and analyzed., Conclusions: The prognosis of soft tissue infections with Saksenaea species. depends on early diagnosis and appropriate antifungal and surgical treatment. Reconstruction can be successful under ongoing antifungal treatment., (Copyright © 2022 The Authors. Published by Wolters Kluwer Health, Inc. on behalf of The American Society of Plastic Surgeons.)

Robotic microsurgery has emerged as a new technology with potential benefits for reconstructive surgery. We report the first-in-human use of the Symani surgical system to perform lympho-venous and arterial anastomosis for lymphatic reconstruction. In five patients, 10 robot-assisted anastomoses were performed. Next to lympho-venous anastomoses, two patients received a free vascularized lymph node transfer. Motion scaling was set to 10×. Visualization was either achieved with a 3D system or an optical microscope. All anastomoses were patent as confirmed by ICG. Despite a longer time to perform the first anastomoses with the robot, we observed a decline in duration of anastomosis. Among the advantages of the system were a high accuracy in placing the stitches even in very small and fragile vessels or when performing anastomoses with size mismatches. The challenges encountered included the lack of a touch sensation and the necessity to develop a "see-feel." This could be achieved surprisingly well because the force necessary to close dilator and needle holder via the manipulators was perceived as comparable to using conventional micro instruments. Our data confirm feasibility and safety of the robotic system to perform lymphatic surgery. Larger patient cohorts and inclusion of surgeons at different training levels will be necessary to investigate the true potential of robotics in microsurgery. In addition, robot-assisted surgery shows a promising potential in opening up new frontiers in reconstructive microsurgery (eg, the reliable performance of anastomoses on even smaller blood and lymphatic vessels or on structures deeper within the body cavities-eg, the thoracic duct)., (Copyright © 2022 The Authors.

Surgery trainees use videos as a means to learn about surgical procedures. YouTube is the biggest online video platform and used for educational content as well but the medical information provided does not undergo peer review or other forms of scientific screening and can thus be of poorer quality. We performed a systematic review that examined the quality of educational videos about surgery and plastic surgery in particular on YouTube. The focus was towards studies on the benefit of YouTube videos for surgical trainees. A literature review was performed to determine the educational quality of plastic surgery videos found on YouTube. Articles reviewing the educational quality of videos about surgical procedures, their accuracy, and their utility for surgical trainees were included. An additional review was performed evaluating the literature about the quality of educational plastic surgery videos. Eleven articles were selected reviewing the educational quality of videos about surgical procedures. Six studies were fully assessed and evaluated concerning the quality of educational plastic surgery videos. There currently seems to be a lack of comprehensive educational surgery and in particular plastic surgery-related information on YouTube. The popularity of YouTube among surgical trainees is high. The quality of available educational surgical video content varies widely. It is in the interest of plastic surgery teaching institutions to provide trainees with high-quality educational video material.

Although previously the mainstay of treatment, the role of surgery in the management of patients with oligometastatic stage IV melanoma has changed with the advent of effective systemic therapies (most notably immunotherapy). Contemporary treatment options for patients with asymptomatic solitary or oligo-metastases include upfront surgery followed by adjuvant immunotherapy or upfront immunotherapy with salvage surgery as required. For suspected solitary or oligo-metastases, surgery serves both diagnostic and therapeutic purposes. Advances in radiological technology allow metastases to be detected earlier and surgery to be less morbid. Surgical morbidities are generally more tolerable than serious immune-related adverse effects, but surgery may be less effective. Upfront immunotherapy ensures that futile surgery is not offered for rapidly progressive disease. It also provides an opportunity to assess response to treatment, which predicts outcome, and may obviate the need for surgery. However, it is important not to miss a window of opportunity for surgical intervention, whereby if disease progresses on immunotherapy it becomes unresectable. In situations where local therapy is recommended but surgery is not desired, stereotactic radiosurgery may be an effective alternative. The decision-making process regarding upfront surgery versus immunotherapy needs to take place within a specialist melanoma multidisciplinary setting and be customised to individual patient and tumour factors. Ultimately, high-level clinical trial evidence is required to resolve uncertainties in the management of patients with oligometastatic stage IV melanoma but the complexity of the varying presentations may make trial design challenging., Competing Interests: Conflict of interest statement The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: MSC has served on advisory boards for Bristol Myers Squibb, MSD, Amgen, Novartis, Pierre Fabre, Roche, Sanofi, Merck, Ideaya, Regeneron, Nektar, Eisai, Oncosec and Qbiotics and has received honoraria from Bristol Myers Squibb, MSD and Novartis.

Over the last years, the layout of surgical training has significantly changed. Surgical residents rely on YouTube videos to prepare for upcoming cases. Eyelid surgery including blepharoplasty ranks among the 5 most often performed cosmetic surgeries. It will be one of those surgeries regularly researched by plastic surgery residents. Therefore, the aim of this study was to evaluate the educational value of the most viewed upper lid blepharoplasty videos on the most popular video broadcasting website, YouTube. A video scoring system consisting of 8 items was developed in accordance with the technical details described in the literature. Video scores were categorized into 3 groups, namely as 'poor', 'moderate; or 'good' in terms of their contribution to surgical education. The first 300 videos were evaluated for the search results for 'blepharoplasty'. After exclusion and summarization of video fragments, a total number of 36 videos were included in the study. Multivariable logistic regression models found no correlation between likes, views, comments and the attributed educational score. The quality of available educational surgical video content varies widely, and surgical trainees need to be critically aware of this as view counts as well as the number of likes and comments will not necessarily relate to videos' educational quality. There is a need for high-quality educational videos.

Background: Lymphoedema is a progressive and potentially disabling disease. A growing number of studies show promising clinical results after microsurgical reconstruction. However, this treatment is currently not supported by level 1 evidence and insurance coverage is variable., Methods: Electronic records of 55 patients with limb lymphoedema, who were eligible for lymphovenous bypass surgery and/or lymphatic tissue transfer in our department from 2017 to 2020, were reviewed. Correspondence between our department and health insurers was analysed. A web-based search and individual telephone interviews were conducted to identify health insurer policies., Results: We included 42 patients undergoing 46 operations and evaluated the correspondence between our department and nine different health insurers. Overall, reimbursement of costs was approved in 67% (n = 31) of all surgeries and was refused in 33% (n = 15). The mean number of applications for reconsideration sent to insurers was 1.3 &plusmn; 0.7. The time between confirmation of the indication and the final decision ranged from 6 to 300 days (mean 50 days). Reimbursement of cost coverage ranged from 0% to 100% depending on the individual insurance company. No insurance company had policies publicly available online and all stated that they determine coverage only when provided with specific patient details on a case-by-case basis., Conclusion: Insurance companies in Switzerland do not have a uniform policy regarding cost coverage for lymphatic surgery procedures. Moreover, the decision process appeared to be rather uniform within the respective insurance company and independent of the individual case. Standardised evaluation criteria including patient reported outcome measures should be developed to underscore the beneficial effects of lymphatic surgery and facilitate insurance coverage.

Objective: Lymphedema is a chronic, progressive and burdensome disease that is known to have a substantial impact on quality of life (QOL). Hence, the assessment of QOL is an important aspect of any study which seeks to evaluate outcomes after lymph reconstructive surgery. We therefore aimed to analyze currently available patient-reported outcome measurements (PROMS) for patients with lower limb lymphedema (LLL) with regard to their psychometric properties. Furthermore, we intended to evaluate the change in QOL in patient undergoing lymphovenous anastomosis (LVA) or vascularized lymph node transfer (VLNT)., Methods: A literature research of four databases on studies that included PROMS for LLL was conducted. All selected studies were assessed for validity according Consensus-based Standards for the selection of Health Measurement Instruments. Studies that used the Lymph Quality of Life Measure for Limb Lymphedema (LYMQOL) after LVA and/or VLNT were included for quantitative analysis., Results: In total, 988 studies were screened, of which 30 studies were included in this review. We identified six validated PROMS to assess LLL. Of those, the LYMQOL was the most commonly used questionnaire. Based on the LYMQOL, a significant improvement of QOL in LLL was noted in all studies after reconstructive lymph surgery (LVA/VLNT) regardless of lymphedema etiology, stage, or time since diagnosis. On the basis of the Consensus-based Standards for the selection of Health Measurement Instruments criteria, the Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema seems to be superior in terms of its psychometric properties., Conclusions: A significant improvement in the QOL in patients with LLL after reconstructive lymph surgery can be observed. Future studies on reconstructive lymph surgery need to include both objective and congruent volume measurements, as well as data on QOL based a well-validated PROM such as the Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema., (Copyright © 2020 Society for Vascular Surgery.

Numerous approaches have been employed to treat chronic lymphocele and cutaneous lymphatic fistulas (LFs) with little success. Given a high incidence and substantial consequences for patients, there is an ongoing demand for effective therapeutic and preventive strategies. The aim of this study was to evaluate the results after microscopic lymphatic ligation (MLL) and lymphovenous anastomosis (LVA) as a therapeutic and preventive approach in this context., Methods: Demographic data, surgical characteristics, complications, and the overall outcome of all patients undergoing surgery for postoperative LF from 2014 to 2019 were collected retrospectively. Patients were categorized in accordance with predefined inclusion/exclusion criteria and with their treatment. Statistical analysis was conducted using descriptive, summary statistics to identify a central tendency., Results: Thirty-four patients underwent indocyanine-green-lymphangiography guided revision surgery for LF. Two patients were lost to follow-up at 6 months. LF was successfully treated in all patients (n = 32) with a multimodal approach. Only MLL was performed in 22 patients and MLL/LVA in 10 patients. LF resolved in 78% of all patients with MLL only or MLL/LVA. In the remaining 22%, LF resolved after additional sclerotherapy within 3 months., Conclusions: Treatment of LF should follow a standardized staged surgical approach to optimize outcome. LF was treated successfully in all our patients. We therefore propose a multimodal interdisciplinary approach to this common clinical problem that includes adjunctive sclerotherapy., (Copyright © 2021 The Authors.

Objective: This study aimed to determine the benefits of sclerotherapy with OK-432 for the treatment of postoperative chronic lymphocele., Background: Postoperative chronic lymphocele formation is common and accounts for a high postoperative morbidity. Nonsurgical strategies comprise repetitive percutaneous fluid aspiration or percutaneous sclerotherapy. OK-432 has been used to treat congenital lymphatic malformations with several reports of promising results. We hypothesized that it is more beneficial than repetitive percutaneous fluid aspiration for the treatment of symptomatic lymphocele., Methods: Two cohorts of melanoma patients who developed recurrent lymphocele after lymph node dissection from January 2013 to August 2017 were compared. The first cohort was treated with repetitive percutaneous fluid aspiration (n = 20). The second cohort received OK-432 sclerotherapy (n = 20). Primary end points were overall treatment duration, number of treatment sessions, and the clinical success in both cohorts. Secondary end points were surgical site infection rate, need for additional antibiotic treatment, wound healing disorders, and the need for revision surgery., Results: Mean overall duration of treatment with sclerotherapy was significantly shorter than with repetitive aspiration (9.4 ± 7.2 vs 47.5 ± 31.9 days, P < 0.01). Mean number of sclerotherapy treatment sessions were 2.5 ± 1.2. Clinical success with OK-432 was 19 of 20, and that with repeated aspiration was 7 of 20 (χ = 15.82, P < 0.001). No surgical site infection occurred in the sclerotherapy cohort, which was significantly lower than those treated with repetitive aspiration (P < 0.03). Surgical revision was mandatory in 12 of 20 patients who were treated with repetitive aspiration, and only 1 of 20 patients in the sclerotherapy cohort., Conclusion: Sclerotherapy with OK-432 for the treatment of postoperative lymphocele is highly beneficial with a significant reduction of morbidity and the overall treatment time compared with repetitive aspiration.

The deep inferior epigastric artery perforator flap (DIEP) has gained widespread popularity in autologous breast reconstruction due to its natural aesthetic results and muscle-sparing design. However, donor site results regarding aesthetic outcome are often less favorable. We therefore aimed to identify crucial factors that might increase the risk for abdominal bulging and an impaired aesthetic appearance. We conducted a multicenter study evaluating all patients receiving autologous breast reconstruction using a DIEP flap between 2013 and 2017. Medical records were analyzed with special attention to flap technique, number of perforators, localization of perforator, and donor site complications. In addition, the aesthetic appearance of the abdominal donor site was evaluated by blinded clinicians at one-year follow-up. A total of 242 patients underwent DIEP flap breast reconstruction. Abdominal bulging occurred in 7%. Further subgroup analysis revealed a significant correlation between abdominal bulging and two or more perforators (P = .003), the use of lateral row perforators (P = .009), and a higher BMI (P = .002). Obesity (P = .003) and higher patient's age (P = .003) could be identified as risk factors for an undesirable appearance of the donor site. We recommend the use of a medial-row single perforator whenever possible in order to optimize donor site morbidity and decrease the risk of abdominal bulging. Proper patient selection and careful donor site closure following a standardized approach should be performed to limit the risk of aesthetically undesirable results., (© 2020 Wiley Periodicals LLC.)

Since the first description many variations of the dorsal metacarpal reverse island flap have been published but there is still uncertainty about which vascular component should be included for an optimal result. Therefore, it was the aim of this study to analyze vascular reliability and ischemic complications of dorsal metacarpal artery perforator (DMAP) flaps and dorsal finger perforator (DFP) flaps in our patient collective. We performed 40 of these flaps from the dorsum of hand and fingers for finger injuries. The choice of donor site was made according to the defect's location. Patients were analyzed with respect to flap necrosis, ischemic complications and achievement of overall reconstruction goals. In addition, we divided our patients in two groups, one group where we raised the flap from the dorsum of the proximal phalanx and a second one where the flaps were raised from the intermetacarpal space to identify complication rates based on the pedicles location. Of the 40 flaps, 36 survived completely. 4 partial necroses were observed in flaps transferred to more distal defects and in one flap that was used in a wrap-around technique for both dorsal and palmar proximal phalanx. These perforator flaps are a reliable method to cover finger defects and the dorsal metacarpal artery is not necessary for their survival, since the blood supply comes from perforating branches of the palmar vascular system. There is a clear trend for a higher complication rate in flaps raised from the dorsum of the fingers compared to the intermetacarpal space.

Background: Social media play an important role in everyday life including medical professional life. Societies like the Federation of European Societies for Surgery of the Hand (FESSH) are acknowledging social media's importance by establishing designated social media committees. No recent publication exists on the use of social media in and for hand surgery., Purpose: The aim of this study was to analyse the current use of social media in and for hand surgery with respect on Instagram., Material and Methods: The 100 top-posts published on Instagram in July 2019 using the hashtags #handsurgery, #handsurgeon and #fessh were analysed regarding the author, the topic and kind of the post, the likes and comments on the post., Results: 101 of the 300 posts were posted by hand surgeons. The majority of posts (172 = 57.3 %) were self-promoting posts; 41 were for medical education. 199 (66.3 %) posts included 1 photo, 63 (21.0 %) two or more photos, and 38 (12.7 %) posts included a video. Video-posts and posts by hand therapists had the most likes and comments., Conclusion: In hand surgery social media is used for self-promotions, but also for medical education. Video-posts are the preferred posts., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Cosmetic Breast Augmentation without Silicone Implants Abstract. Cosmetic breast augmentation procedures without silicone implants are becoming increasingly popular. Mastopexy can be adapted to the needs of the patient and usually result in an at least optical augmentation. Lipofilling is a safe procedure in reconstructive and aesthetic breast surgery and can help to restore natural appearance, compensate volume deficiencies, and correct asymmetries, that may be congenital or a consequence of prior surgeries. Cosmetic breast augmentation of very small breasts or when aiming at higher breast volumes using lipofilling only are usually combined with procedures for tissue expansion in order to increase the take rate of the injected fat. Hyaluronic acid injections is no valid alternative and are not recommended for cosmetic breast augmentation.

Introduction: Identification of patent lymphatic vessels without fibrosis and with high flow is difficult but crucial in the preoperative planning of lymphaticovenous anastomosis (LVA). Lymphatic vessels on the operating field cannot always be visualized preoperatively because of the anatomical and physiological characteristics of lymphedema tissue. The purposes of this study were to demonstrate our clinical experience in identifying indocyanine green (ICG)-negative lymphatics intraoperatively and to emphasize the therapeutic potential of performing anastomoses with ICG-negative lymphatics., Methods: Indocyanine green-positive lymphatic ducts were marked preoperatively in 5 patients with lower extremity lymphedema; moreover, if ICG-negative lymphatics were identified during surgery, they were used for additional LVA thus implementing multiple anastomoses in one surgical setting., Results: In total, 33 LVAs were performed in 5 patients with lower extremity lymphedema, of which 11 LVAs were implemented with ICG-negative lymphatics. Immediately after the anastomosis, a strong lymphatic drainage could be appreciated in all cases. Six months postoperatively patients reported a subjective decrease in limb circumference and pressure sensation., Conclusions: We believe that ICG-negative lymphatics found intraoperatively should be evaluated for additional LVAs in order to maximize drainage effect and might provide better outcomes.

Lymphedema most commonly occurs after cancer treatment and can affect limbs and genitalia. Genital lymphedema (GL) is a rare condition and can be disabling psychologically and physically. It often occurs along with lower extremity lymphedema (LEL). Conservative and physiologic reconstructive surgery such as lymphaticovenous anastomosis (LVA) offer good treatment options for LEL. GL however remains a reconstructive dilemma. The most effective surgical therapies in advanced GL are still debulking procedures in properly selected patients. Here, we present the surgical treatment of a 51 -year-old male patient with advanced and combined genital and right lower extremity lymphedema after Hodgkin lymphom treatment in the childhood. We performed multiple LVA to the right ankle joint, distal lower leg and lateral knee and 2 months later patient reported a significant decrease of pain and pressure in affected limb while the scrotal and penis lymphedema did not show any signs of improvement at all. Four months later, 4.9 kg of excessive lymphedematous tissue from the genital area was resected and covered by split-thickness skin grafts from the unaffected left upper thigh. The postoperative course was uneventful and 3 weeks postoperatively the skin graft healed completely. Follow up at 6 months showed reasonable cosmetic and functional outcomes and the patient reported a significant improvement of quality of life. We believe that debulking procedures and LVA may be combined in advanced GL and LEL and may provide good outcomes., (© 2018 Wiley Periodicals, Inc.)

The pedicled medial plantar (MP) flap is an optimal solution for defects involving the weight-bearing areas of the foot. However, venous congestion is a frequently encountered complication, especially with the reverse-flow variants of the flap, and several strategies have been reported in literature both to prevent and to manage it. In this article, we present the use of a medial plantar flap based distally on the lateral plantar artery with the adjunct of an extra metatarsal perforator from the dorsalis pedis artery as a vascular enhancement to avoid the venous congestion and to improve the overall circulation. This bipedicled flap was successfully advanced to cover a 5 × 3 cm soft-tissue defect located at the level of the first and second metatarsal heads of the right foot resulting from the excision of a squamous cell carcinoma in an 80-year-old male patient with a history of cardiovascular disease. The postoperative course was uneventful. The patient was discharged 7 days after the operation and was able to walk after 6 weeks wearing normal shoes. We believe that preserving plantar metatarsal perforators during the harvesting of an MP flap based distally on the lateral plantar artery may be a precious adjunct as it increases blood supply, especially the venous drainage of the flap., (© 2018 Wiley Periodicals, Inc.)

Background: Fat grafting has been gaining attention in tissue augmentation over the past decade, not only for lipofilling, but also for its observed regenerative properties and overall skin texture improvement., Objectives: The aim of this study was to analyze the effect of nanofat grafting on scars, wrinkles, and skin discolorations in our clinic., Methods: Nanofat was prepared by a standard emulsification and filtration protocol. The resulting liquid was injected intradermally or directly into the scar tissue. Skin quality was evaluated based on a scoring system, and patient satisfaction was documented. Three physicians compared and analyzed standardized pre- and posttreatment photographs in respect to general improvement of skin aesthetics., Results: Fifty-two patients were treated with nanofat from November 2013 to April 2016. The mean (± standard deviation) posttreatment follow up was 155 ± 49 days and average volume of harvested fat amounted to 165 cc. The primary harvesting areas were the abdomen and flanks, and the injected volume of nanofat ranged from 1 to 25 mL (mean, 4.6 mL). A total of 40 scars (76% of all patient defects) were effectively treated as well as 6 patients with wrinkles, and 6 patients with discoloration. Posttreatment clinical evaluations showed a marked improvement of scar quality and a high patient satisfaction. The results in our clinic showed that nanofat grafting softened the scars, made discolorations less pronounced, and wrinkles appeared less prominent., Conclusions: Nanofat grafting has been shown to have beneficial effects in the treatment of scars, wrinkles, and skin discolorations.

Objectives: The aim of the study was to assess the effect of art including ambient features such as music, interior design including visual art, and architectural features on health outcomes in surgical patients., Background: Healing environments can have a positive influence on many patients, but data focusing on art in surgical patients remain scarce., Methods: We conducted a systematic search following the PRISMA guidelines from January 2000 to October 2014 on art in surgical patients. For music interventions, we pooled controlled studies measuring health outcomes (eg, pain, anxiety, blood pressure, and heart rate) in a meta-analysis. For other art forms (ambient and architectural features and interior design), we did a narrative review, also including nonsurgical patients, and looked for examples covering 3 countries., Results: Our search identified 1101 hits with 48 studies focusing on art in surgical patients: 47 studies on musical intervention and 1 on sunlight. The meta-analysis of these studies disclosed significant effects for music on pain after surgery, anxiety, systolic blood pressure, and heart rate, when compared with control groups without music. Effects of music were larger with self-selected music, and lower in surgical interventions performed under general anesthesia. Interior design features such as nature images and more spacious rooms, and architectural features providing more sunlight had positive effects on anxiety and postoperative pain., Conclusions: Self-selected music for surgical patients is an effective and low-cost intervention to enhance well being and possibly faster recovery. Although potentially very important, the impact of environmental features and spacious architecture with wide access to sunlight remains poorly explored in surgery. Further experimental research is needed to better assess the magnitude of the impact and cost effectiveness.
