[PMID: 37057889 PMCID: PMC10389392 DOI: 10.1097/js9.0000000000000210] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 01/03/2023] [Indexed: 04/15/2023]
Abstract
BACKGROUND Microsurgical treatment options for lymphedema consist mainly of lymphovenous anastomosis (LVA) and vascularized lymph node transfers (VLNTs). There are no standard measurements of the effectiveness of these interventions and reported outcomes vary among studies. METHODS A systematic review and meta-analysis were performed based on a structured search in Embase, Medline, PubMed, Cinahl, Cochrane, and ProQuest in October 2020, with an update in February 2022. Firstly, a qualitative summary of the main reported outcomes was performed, followed by a pooled meta-analysis of the three most frequently reported outcomes using a random effects model. Randomized controlled trials, prospective cohorts, retrospective cohorts, and cross-sectional and case-control studies that documented outcomes following microsurgery in adult patients were included. Studies of other surgical treatments (liposuction, radical excision, lymphatic vessel transplantation) or without reported outcomes were excluded. The study protocol was registered on PROSPERO (International Prospective Register of Systematic Reviews) (ID: CRD42020202417). No external funding was received for this review. RESULTS One hundred fifty studies, including 6496 patients, were included in the systematic review. The qualitative analysis highlighted the three most frequently reported outcomes: change in circumference, change in volume, and change in the number of infectious episodes per year. The overall pooled change in excess circumference across 29 studies, including 1002 patients, was -35.6% [95% CI: -30.8 to -40.3]. The overall pooled change in excess volume across 12 studies including 587 patients was -32.7% [95% CI: -19.8 to -45.6], and the overall pooled change in the number of cutaneous infections episodes per year across 8 studies including 248 patients was -1.9 [95% CI: -1.4 to -2.3]. The vast majority of the studies included were case series and cohorts, which were intrinsically exposed to a risk of selection bias. CONCLUSION The currently available evidence supports LVA and vascularized lymph node transfers as effective treatments to reduce the severity of secondary lymphedema. Standardization of staging method, outcomes measurements, and reporting is paramount in future research in order to allow comparability across studies and pooling of results.

Abstract
UNLABELLED Lymphovenous anastomosis (LVA) is a microsurgical treatment for lymphedema of the lower extremity (LEL). This study systematically reviews the most recent data on outcomes of various LVA techniques for LEL in diverse patients. METHODS A comprehensive literature search was conducted in the Ovid MEDLINE, Ovid EMBASE, and Scopus databases to extract articles published through June 2021. Studies reporting data on objective postoperative improvement in lymphedema and/or subjective improvement in quality of life for patients with LEL were included. Extracted data comprised demographics, number of patients and lower limbs, duration of symptoms before LVA, surgical technique, duration of follow-up, and objective and subjective outcomes. RESULTS A total of 303 articles were identified and evaluated, of which 74 were ultimately deemed eligible for inclusion in this study, representing 6260 patients and 2554 lower limbs. The average patient age ranged from 22.6 to 76.14 years. The duration of lymphedema before LVA ranged from 12 months to 11.4 years. Objective rates of improvement in lymphedema ranged from 23.3% to 100%, with the greatest degree of improvement seen in patients with early-stage LEL. CONCLUSIONS LVA is a safe and effective technique for the treatment of LEL of all stages. Several emerging techniques and variations may lead to improved patient outcomes.

Abstract
BACKGROUND Although several investigations have described the safety, utility, and precision of magnetic resonance lymphography (MRL) as a preoperative examination for lymphaticovenular anastomosis (LVA), it is unclear how much MRL assistance impacts LVA results. The present study aimed to clarify the outcome of MRL-assisted LVA for leg lymphedema using body water measurements obtained by bioelectrical impedance analysis. METHODS The water reductive effect of MRL-assisted LVA in female secondary leg lymphedema patients was compared with that of non-MRL-assisted controls in this retrospective study. In the MRL-assisted group, all LVA candidates underwent MRL prior to surgery, and the lymphatic vessels to be anastomosed were primarily determined by MRL findings. The body water composition of the treated legs was assessed before LVA and at 6 months postoperatively using a multi-frequency bioelectrical impedance analyzer. RESULTS Twenty-three patients in the MRL-assisted study group and an equal number in the non-MRL-assisted control group were analyzed. Although mean leg water volume before LVA, mean excess water volume of the affected leg before LVA, and number of anastomoses created were comparable between the groups, the water volume reduction (1.02 L versus 0.49 L; 95% confidence interval [CI]: 0.03-1.03, p < 0.05) and edema reduction rate (46.7% versus 27.2%; 95% CI: 3.7-35.5%, p < 0.05) in the MRL-assisted group were significantly greater than in controls. CONCLUSION Preoperative MRL-assisted lymph vessel visualization and selection appeared to significantly enhance the water reductive effect of LVA for International Society of Lymphology classification stage 2 leg lymphedema. MRL also helped to reliably identify lymphatic vessels for anastomosis. Without increasing the number of anastomoses, LVA could be performed more effectively by better detecting stagnant lymphatic vessels using MRL.

Abstract
Patients presenting with chronic wounds in venous insufficiency often represent a challenge, like other conditions, like lymphatic impairment, may complicate the wound healing process. The purpose of this report is to highlight how the treatment of lymphatic impairment may be beneficial in patients affected by chronic ulcers with concomitant venous insufficiency. We present the case of a 78-year-old woman affected by chronic venous insufficiency (CVI) with long-lasting ulcers secondary to sclerosing agents treatment for varicose veins. The patient's condition was refractory to both conservative and surgical treatment. Since the patient also presented with severe lymphorrhea, with a significant amount of daily secretion, ICG-lymphography was performed subcutaneously, to visualize the pathway of lymphatic drainage and leakage. It also allowed marking on the skin the exact location of lymphatic vessels distally to the wound area. Hence, two lymphatico-venous anastomoses were performed between the two major collecting lymphatic vessels and two subcutaneous veins of adequate size. The postoperative course was uneventful and the procedure allowed for immediate resolution of lymphatic leakage and complete wound healing within 2 weeks with no recurrence in the follow-up time of 1.5 years. Based on the outcomes of this case, it is possible to consider the use of CVI treatment and lymphedema surgery as a combined approach to complicated cases of long-standing venous ulcers with lymphorrhea.

Abstract
BACKGROUND Secondary lymphedema after surgical interventions is a progressive, chronic disease that is still not completely curable. Over the past years, a multitude of surgical therapy options have been described.
AIM To summarize the single-center complications in lymph vessel (LVTx) and free vascularized lymph node transfer (VLNT).
METHODS In total, the patient collective consisted of 87 patients who were undergoing treatment for secondary leg lymphedema during the study period from March 2010 to April 2020. The data collection was performed preoperatively during consultations, as well as three weeks, six months and twelve months after surgical treatment. In the event of complications, more detailed follow-up checks were carried out. In total n = 18 robot-assisted omental lymph node transplantations, n = 33 supraclavicular lymph node transplantations and n = 36 Lymph vessel transplantations were analyzed. An exemplary drawing is shown in Figure 1. A graphical representation of patient selection is shown in Figure 2. Robotic harvest was performed with the Da Vinci Xi Robot Systems (Intuitive Surgical, CA, United States).
RESULTS In total, 11 male and 76 female patients were operated on. The mean age of the patients at study entry was: omental VLNT: 57.45 ± 8.02 years; supraclavicular VLNT: 49.76 ± 4.16 years and LVTx: 49.75 ± 4.95 years. The average observation time postoperative was: omental VLNT: 18 ± 3.48 mo; supraclavicular VLNT: 14.15 ± 4.9 and LVTx: 14.84 ± 4.46 mo. In our omental VLNT, three patients showed a slight abdominal sensation of tension within the first 12 postoperative days. No other donor side morbidities occurred. No intraoperative conversion to open technique was needed. Our supraclavicular VLNT collective showed 10 lift defect morbidities with one necessary surgical intervention. In our LVTx collective, 12 cases of donor side morbidity were registered. In one case, surgical intervention was necessary.
CONCLUSION Concerning donor side morbidity, robot-assisted omental VLNT is clearly superior to supraclavicular lymph node transplantation and LVTx.

Abstract
BACKGROUND Lymphaticovenular anastomosis (LVA) with supramicrosurgical technique has recently gained popularity as a treatment method for patients with lymphedema. The aim of this study was to prospectively evaluate objective changes in leg volume in patients operated with LVA for lymphedema in the lower extremity, and to find positive predictors for the treatment method to facilitate the location of the venules and lymphatic vessels. PATIENTS & METHODS 31 consecutive patients with lymphedema in the lower extremity and positive pitting test were examined with lymphoscintigraphy and indocyanine green (ICG) lymphography. The causes of the lymphedema were either cancer or unknown cause/primary lymphedema. Fourteen of the patients with pathological lymphangiographic patterns were chosen for surgery and 12 of them were operated with one to four LVAs each. The lymphedema volume in the lower extremity was measured preoperatively, 6- and 12 months after surgery according to the truncated cone formula with the patient´s contralateral leg used as control. Ten patients had unilateral lymphedema and two patients had bilateral lymphedema. RESULTS Five of 12 patients showed between 1-8% edema reductions in the lower extremity after 12 months. With examination considering edema duration, number of anastomoses, radiotherapy and lymph node dissection we found a 6,2% difference in edema reduction between patients who had undergone lymph node dissection and those who had not (p = 0.03). CONCLUSIONS The current study indicates that supramicrosurgery with LVA may reduce edema volumes, where the most distinctive positive predictor for edema reduction with LVAs was previous lymph node dissection.

Abstract
AbstractBackground We previously examined the water reductive effect of lymphaticovenular anastomosis (LVA) using bioelectrical impedance analysis (BIA) measurement on lower-limb lymphedema and revealed mean water volume reduction and edema reduction rate by leg LVA to be 0.86 L and 45.1%, respectively. This study aimed to clarify the water reductive effect of LVA on arm lymphedema and compare its results with those for leg lymphedema.Patients and Methods The efficacy of LVA for unilateral arm lymphedema was evaluated using BIA in a retrospective cohort. Limb circumference and arm body water volume (ABW) of the affected and unaffected arms were measured before and after LVA. Mean water volume reduction (ΔABW) and edema reduction rate by arm LVA were compared with values for leg LVA cited from our previous report as a historical control.Results Nineteen consecutive patients were enrolled. The mean ΔABW and edema reduction rate by BIA were 0.267 L and 46.0%, respectively. The decreasing rate of ABW by BIA was significantly larger than those of the upper extremity lymphedema index and sum of 5 circumferences measurement methods. ΔABW could be predicted by a regression line based on the preoperative water volume difference between affected and unaffected limbs. The mean edema reduction rates for arm and leg LVA were comparable.Conclusion The water reductive effect of LVA on upper-limb lymphedema was demonstrated by BIA assessment. BIA can reflect the effect of LVA more sensitively than conventional objective measurements and may facilitate the interpretation of LVA results. Although water volume reduction by arm LVA was less than that by leg LVA, the edema reduction rates were comparable.
