Acupuncture Treatment for Breast Cancer-Related Lymphedema: A Randomized Pilot Study.

Background: Methods of conservative management for breast cancer-related lymphedema (BCRL) are burdensome in terms of time, cost, and convenience. In addition, many patients are not candidates for surgical treatment. Preliminary results have demonstrated possible beneficial effects of acupuncture for patients with BCRL. In this small pilot study, we examined the safety and feasibility of an acupuncture randomized control trial (RCT) in this patient cohort, utilizing a battery of standardized clinical and patient-centered outcome measures. Methods and Results: Patients with BCRL were randomized 2:1 to the acupuncture (n = 10) or the control (n = 4) group. Patients received acupuncture to the unaffected extremity biweekly for 6 weeks. Feasibility was defined as enrollment ≥80%, completion of ≥9 of 12 acupuncture sessions per person, and ≥75% completion of three of three measurement visits. To inform a future adequately powered RCT, we describe within-group changes in patient-centered outcomes, including circumferential measurements, bioimpedance spectroscopy, perometry, cytokine levels, and patient quality of life. Adverse events were systematically tracked. Fourteen patients completed the study. Of those who received acupuncture (n = 10), 8 completed all 12 acupuncture sessions, and 2 patients completed 11 sessions. Ninety-three percent of all participants completed all three measurement visits. There was no consistent improvement in arm volumes. Inflammatory marker levels had inconclusive fluctuations among both groups. All patients receiving acupuncture demonstrated an improvement in their functional quality-of-life score. No severe adverse events occurred. Conclusions: A randomized controlled study of acupuncture for BCRL is feasible. The acupuncture intervention is acceptable in this population, without safety concerns in a small sample and warrants further investigation.

A 4-Year Institutional Experience of Immediate Lymphatic Reconstruction.

BACKGROUND: Up to one in three patients may go on to develop breast cancer-related lymphedema (BCRL) after treatment. Immediate lymphatic reconstruction (ILR) has been shown in early studies to reduce the risk of BCRL, but long-term outcomes are limited because of its recent introduction and institutions' differing eligibility requirements. This study evaluated the incidence of BCRL in a cohort that underwent ILR over the long term. METHODS: A retrospective review of all patients referred for ILR at the authors' institution from September of 2016 through September of 2020 was performed. Patients with preoperative measurements, a minimum of 6 months of follow-up data, and at least one completed lymphovenous bypass were identified. Medical records were reviewed for demographics, cancer treatment data, intraoperative management, and lymphedema incidence. RESULTS: A total of 186 patients with unilateral node-positive breast cancer underwent axillary nodal surgery and an attempt at ILR over the study period. Ninety patients underwent successful ILR and met all eligibility criteria, with a mean patient age of 54 ± 12.1 years and median body mass index of 26.6 kg/m 2 [interquartile range (IQR), 24.0 to 30.7 kg/m 2 ]. The median number of lymph nodes removed was 14 (IQR, eight to 19). Median follow-up was 17 months (range, 6 to 49 months). Eighty-seven percent of patients underwent adjuvant radiotherapy, and among them, 97% received regional lymph node irradiation. The overall rate of lymphedema was 9% at the end of the study period. CONCLUSIONS: With the use of strict follow-up guidelines over the long term, the authors' findings support that ILR at the time of axillary lymph node dissection is an effective procedure that reduces the risk of BCRL in a high-risk patient population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Creating a Policy for Coverage of Lymphatic Surgery: Addressing a Critical Unmet Need.

SUMMARY: This article describes the key stakeholders and process involved in developing an insurance policy in the United States to establish medical necessity criteria for lymphatic surgery procedures. Lymphedema is a chronic health issue that impacts over 1.2 million patients and is associated with lifelong health, economic, and psychosocial costs. Patients affected have been described as "medical nomads," as they often interface with multiple providers before receiving an accurate diagnosis and treatment. This underscores the lack of attention and understanding about this disease across all sectors of the medical system. Unlike nations including Sweden and the United Kingdom, which provide insurance coverage for treatment, the United States has lagged behind. As a country, we have neglected to fully recognize the consequences of inadequate treatment of lymphedema, including chronic morbidities such as loss of mobility, psychosocial sequelae, recurrent infections, and even death. Recently, the authors' lymphatic center had the unique opportunity to help develop a policy that merged their clinical experience, recently established lymphatic care center of excellence criteria, and third-party payer policy expertise. This experience spanned 1 year from June of 2018 to June of 2019. The authors identify how key partnerships helped fill evidentiary gaps that ultimately resulted in policy change.

Superficial and Functional Lymphatic Anatomy of the Upper Extremity.

BACKGROUND: Knowledge of detailed lymphatic anatomy in humans is limited, as the small size of lymphatic channels makes it difficult to image. Most current knowledge of the superficial lymphatic system has been obtained from cadaveric dissections. METHODS: Indocyanine green lymphography was performed preoperatively to map the functional arm lymphatics in breast cancer patients without clinical or objective evidence of lymphedema. A retrospective review was performed to extract demographic, indocyanine green imaging, and surgical data. RESULTS: Three main functional forearm channels with variable connections to two upper arm pathways were identified. The median forearm channel predominantly courses in the volar forearm (99 percent). The ulnar forearm channel courses in the volar forearm in the majority of patients (66 percent). The radial forearm channel courses in the dorsal forearm in the majority of patients (92 percent). Median (100 percent), radial (91 percent), and ulnar (96 percent) channels almost universally connect to the medial upper arm channel. In contrast, connections to the lateral upper arm channel occur less frequently from the radial (40 percent) and ulnar (31 percent) channels. CONCLUSIONS: This study details the anatomy of three forearm lymphatic channels and their connections to the upper arm in living adults without lymphatic disease. Knowledge of these pathways and variations is relevant to any individual performing procedures on the upper extremities, as injury to the superficial lymphatic system can predispose patients to the development of lymphedema.

Designing a Plastic and Reconstructive Surgery Virtual Curriculum: Assessment of Medical Student Knowledge, Surgical Skill, and Community Building.

BACKGROUND: The COVID-19 pandemic displaced medical students from their rotations and into virtual classrooms. The authors aimed to develop a virtual curriculum with the goals for students to gain knowledge in plastic surgery, to acquire technical skills, and to be able to promote community. METHODS: The authors developed a 4-week educational curriculum of topics in plastic surgery using the American Society of Plastic Surgeons Resident Education Curriculum and an online plastic surgery curriculum. Virtual flipped classroom case discussions and weekly surgical skills workshops were offered. Precourse and postcourse surveys were administered, and results were analyzed using IBM SPSS Statistics version 25.0. RESULTS: Three hundred three medical students and recent graduates enrolled in the course in June of 2020. One hundred eighty-two students completed the precourse survey (60 percent response rate), and of those, 50.0 percent ( n = 91) completed the postcourse survey for paired comparison. Students reported significant improvement in confidence discussing the relevant anatomy, workup, and surgical approaches to clinical cases, in addition to confidence in knowledge of all topic areas ( p < 0.001). Confidence in suturing and knot-tying techniques improved significantly among workshop participants ( p < 0.001). Students applying to residency programs this cycle felt significantly more prepared for subinternships ( p < 0.001) and significantly more connected to the community of applicants ( p < 0.001). CONCLUSIONS: The Plastic and Reconstructive Surgery Virtual Curriculum improved knowledge, surgical skills, and community in the field among medical student participants. This course may serve to provide a framework for structured virtual learning activities for students interested in plastic surgery and may have significant long-lasting utility for students interested in the field.

Chaperone Use During Plastic Surgery Physical Examinations: Nationwide Provider Practices and Impact of Level of Training.

BACKGROUND: Medical chaperones often play an important role during physical examinations, providing patient comfort and serving as medicolegal witness. The purpose of this study was to evaluate and compare practices regarding chaperone use by plastic surgery attendings and trainees. METHODS: A voluntary survey was distributed to members of the American Council of Academic Plastic Surgeons. The survey included a standardized set of questions regarding physician demographics, nature of practice training, and current practices pertaining to chaperone use. Data were analyzed in a descriptive fashion. Ordinal logistic regression models were used to identify predictors of chaperone use. RESULTS: We received 167 responses, of which 107 (64.1%) were attendings and 60 (35.9%) were trainees. In total, 78.3% of the respondents were male and 21.7% were female. Routine use of chaperones was reported at 58.6%. Compared with plastic surgery trainees, attending surgeons were 12.8 times more likely to use a chaperone during sensitive examinations (P < 0.001). In addition, male respondents were 6.43 times more likely than their female counterparts to involve a chaperone during sensitive examinations (P < 0.001). Forty-eight percent of the trainees acknowledged receiving education regarding chaperone use, and this cohort was 7 times more likely to use a chaperone when compared with trainees who had not received chaperone instruction (P < 0.001). CONCLUSIONS: This study highlights the wide variability of chaperone use among plastic surgery attendings and trainees. Integration and standardization of chaperone education within plastic surgery training may be an effective technique to promote this practice and lead to improved patient-provider clinical experiences.

Novel Quantification of Real-Time Lymphatic Clearance: Immediate Lymphatic Reconstruction in a Large-Animal Model.

BACKGROUND: The real-time quantification of lymphatic flow remains elusive. Efforts to provide a metric of direct lymphatic function are not clinically translatable and lack reproducibility. Early reports demonstrate the promise of immediate lymphatic reconstruction (immediate lymphovenous bypass after lymphadenectomy) to reduce the risk of lymphedema development. However, there remains a heightened need to appraise this technique in a clinically translatable large-animal model. The aim of the authors' experiment was to evaluate the role of molecular imaging in the quantification of real-time lymphatic flow after lymphadenectomy, and lymphadenectomy with lymphovenous bypass using novel fluorophores in a swine model. METHODS: A lymphadenectomy or lymphadenectomy with subsequent lymphovenous bypass was performed in 10 female swine. After subdermal fluorophore injection, near-infrared molecular imaging of blood samples was used to evaluate change in lymphatic flow after lymphadenectomy versus after lymphadenectomy with lymphovenous bypass. Continuous imaging evaluating fluorescence of the superficial epigastric vein in the torso and adjacent skin was performed throughout all experiments. Findings between modalities were correlated. RESULTS: The near-infrared dye signal in central and peripheral blood samples was often difficult to separate from background and proved challenging for reliable quantification. Venous and skin near-infrared imaging demonstrated a lymphatic clearance rate decrease of 70 percent after lymphadenectomy versus a decrease by only 30 percent after lymphadenectomy with immediate lymphovenous bypass. CONCLUSIONS: In this article, the authors describe a noninvasive, swine, large-animal model to quantify lymphatic clearance using skin imaging. The authors' findings were consistent with results yielded from real-time imaging of the vein. The authors believe this model may have important implications for eventual direct translation to the clinical setting.

A Single Institution Multi-disciplinary Approach to Power-assisted Liposuction for the Management of Lymphedema.

OBJECTIVE: To implement and evaluate outcomes from a comprehensive, multi-disciplinary debulking program in the United States. SUMMARY OF BACKGROUND DATA: Interest in and access to surgical treatment for chronic lymphedema (LE) in the United States have increased in recent years, yet there remains little attention on liposuction, or debulking, as an effective treatment option. In some other countries, debulking is a common procedure for the surgical treatment of LE, is covered by insurance, and has demonstrated excellent, reproducible outcomes. In this study we describe our experience implementing a debulking technique from Sweden in the United States. METHODS: Patients who presented with chronic LE followed a systematic multi-disciplinary work-up. For debulking with power assisted liposuction, the surgical protocol was modeled after that developed by Håkan Brorson. A retrospective review of consecutive patients who underwent debulking at our institution was conducted. RESULTS: Between December 2017 and January 2020, 39 patients underwent 41 debulking procedures with power assisted liposuction, including 23 upper and 18 lower extremities. Mean patient age was 58 years and 85% of patients had LE secondary to cancer, the majority of which (64%) was breast cancer. Patients experienced excess volume reductions of 116% and 115% in the upper and lower extremities, respectively, at 1 year postoperatively. Overall quality of life (LYMQOL) improved by a mean of 33%. Finally, patients reported a decreased incidence of cellulitis and decreased reliance on conservative therapy modalities postoperatively. CONCLUSIONS: Debulking with power assisted liposuction is an effective treatment for patients with chronic extremity LE. The operation addresses patient goals and improves quality of life, and additionally reduces extremity volumes, infection rates and reliance on outpatient therapy. A comprehensive, multi-disciplinary debulking program can be successfully implemented in the United States healthcare system.

Use of non-contrast MR in diagnosing secondary lymphedema of the upper extremities.

PURPOSE: The purpose of the study is to determine if a combination of dermal thickening and subcutaneous fluid honeycombing on non-contrast MRI, termed the dermal rim sign (DRS), can be diagnostically analogous to dermal backflow seen on lymphoscintigraphy in patients with secondary upper extremity lymphedema. MATERIALS AND METHODS: Upper extremity MRI and lymphoscintigraphy were performed on patients referred to a multidisciplinary lymphedema clinic for suspicion of secondary lymphedema. Sensitivity, specificity, and positive and negative predictive values of DRS on MRI in detecting dermal backflow on lymphoscintigraphy and the correlation between DRS, Indocyanine Green (ICG) lymphography, bioimpedence L-Dex® ratio and MRI Lymphedema Staging were calculated. Weighted interobserver agreements on the presence and location of DRS on MRI were calculated. RESULTS: Of the 45 patients in the study, 91.1% (41/45) of patients had history of breast cancer. The average age was 58.4 ± 10.5 years, with a mean symptom duration of 4.7 ± 4.4 years. The mean BMI was 30.5 ± 7.0 kg/m2. Interobserver agreement on the presence and the extent of DRS on MRI was 0.93 [95% confidence-interval: 0.80-1]. DRS was present in 97% (32/33) of patients who demonstrated dermal backflow on lymphoscintigraphy. Sensitivity, specificity, PPV, and NPV of DRS were 96.6% [81.7%-99.9%], and 75.0% [47.6%-92.7%], 87.5% [74.9%-94.3%], and 92.3% [63.1%-98.8%]. DRS was associated with severity on ICG lymphography and bioimpedance (both p < 0.001). CONCLUSIONS: DRS on non-contrast MRI is highly predictive of dermal backflow and correlates with clinical measures of lymphedema severity. DRS may be used as an independent diagnostic biomarker to identify patients who would benefit from dedicated exams.

Evaluating the Impact of Immediate Lymphatic Reconstruction for the Surgical Prevention of Lymphedema.

BACKGROUND: Breast cancer-related lymphedema affects one in five patients. Its risk is increased by axillary lymph node dissection and regional lymph node radiotherapy. The purpose of this study was to evaluate the impact of immediate lymphatic reconstruction or the lymphatic microsurgical preventative healing approach on postoperative lymphedema incidence. METHODS: The authors performed a retrospective review of all patients referred for immediate lymphatic reconstruction at the authors' institution from September of 2016 through February of 2019. Patients with preoperative measurements and a minimum of 6 months' follow-up data were identified. Medical records were reviewed for demographics, cancer treatment data, intraoperative management, and lymphedema incidence. RESULTS: A total of 97 women with unilateral node-positive breast cancer underwent axillary nodal surgery and attempt at immediate lymphatic reconstruction over the study period. Thirty-two patients underwent successful immediate lymphatic reconstruction with a mean patient age of 54 years and body mass index of 28 ± 6 kg/m2. The median number of lymph nodes removed was 14 and the median follow-up time was 11.4 months (range, 6.2 to 26.9 months). Eighty-eight percent of patients underwent adjuvant radiotherapy of which 93 percent received regional lymph node radiotherapy. Mean L-Dex change was 2.9 units and mean change in volumetry by circumferential measurements and perometry was -1.7 percent and 1.3 percent, respectively. At the end of the study period, we found an overall 3.1 percent rate of lymphedema. CONCLUSION: Using multiple measurement modalities and strict follow-up guidelines, the authors' findings support that immediate lymphatic reconstruction at the time of axillary surgery is a promising, safe approach for lymphedema prevention in a high-risk patient population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Breast Cancer-Related Lymphedema: Magnetic Resonance Imaging Evidence of Sparing Centered Along the Cephalic Vein.

BACKGROUND: A distinct pattern of edema distribution is seen in breast cancer-related lymphedema. The area of edema sparing has not been characterized in relation to anatomy. Specifically, alternate lymphatic pathways are known to travel adjacent to the cephalic vein. Our study aims to define the location of edema sparing in the arm relative to the cephalic vein. METHODS: A retrospective review of patients who underwent magnetic resonance imaging (MRI) between March 2017 and September 2018 was performed. Variables including patient demographics, arm volumes, and MRI data were extracted. MRIs were reviewed to define the amount of sparing, or angle of sparing, and the deviation between the center of sparing and the cephalic vein, or angle of deviation. RESULTS: A total of 34 consecutive patients were included in the analysis. Five patients demonstrated circumferential edema (no sparing) and 29 patients demonstrated areas of edema sparing. Advanced age (69.7 vs. 57.6 years) and greater excess arm volume (40.4 vs. 20.8%) correlated with having circumferential edema without sparing (p = 0.003). In 29 patients with areas of edema sparing, the upper arm demonstrated the greatest angle of sparing (183.2 degrees) and the narrowest in the forearm (99.9 degrees; p = 0.0032). The mean angle of deviation to the cephalic vein measured 3.2, -0.1, and -5.2 degrees at the upper arm, elbow, and forearm, respectively. CONCLUSION: Our study found that the area of edema sparing, when present, is centered around the cephalic vein. This may be explained by the presence of the Mascagni-Sappey (M-S) pathway as it is located alongside the cephalic vein. Our findings represent a key springboard for additional research to better elucidate any trends between the presence of the M-S pathway, areas of sparing, and severity of lymphedema.

Beyond the Tip of the Blade: An Investigation of Upper Extremity Machete Injuries in Honduras.

BACKGROUND: Machete injuries constitute a major cause of morbidity in Honduras. In this study, we aimed to determine the incidence, initial management, surgical treatment, and follow-up patterns for machete injuries at the national public hospital in Honduras. Microsurgery in Honduras is currently in transition with limitations at multiple levels. This study aims to provide critical information to better prepare visiting surgeons and establishes a blueprint to improve microsurgical reconstruction. METHODS: A retrospective chart review was performed to identify patients with machete injuries to the upper extremity (UE) who presented to the Hospital Escuela Universitario (HEU) for treatment from 2015 to 2017. Additional microsurgical data was obtained by personal communication with members of the plastic surgery department at the HEU. RESULTS: Complete data was retrieved for 100 patients who presented to the HEU with a UE machete wound. The cohort was male dominated (93%), employed as farmers (47%), and had a mean age of 32.1 years. Violence was the most common mechanism of injury (p < 0.001). The majority of UE machete injuries involved tendon (70%), nerve (28%), and an open fracture (55%). Of the 76% of patients who were scheduled for a follow-up visit, only 25% attended. Within the last calendar year, one replantation, 10 revascularizations at the wrist and forearm level, three microvascular free tissue transfers, and 175 nerve repairs were performed. CONCLUSION: Management of UE machete injuries in Honduras is challenging and requires early recognition of possible injuries to multiple anatomical systems. The majority of injuries required operative intervention. Only a small percentage of patients presented for follow up. A program to streamline care starting at injury recognition up to final follow-up is currently unavailable and needs to be developed to optimize microsurgical care.

Is Immediate Lymphatic Reconstruction Cost-effective?

Mini: We conducted a cost-utility analysis to evaluate the cost and quality of life of patients undergoing axillary lymph node dissection (ALND) and ALND with regional lymph node radiation (RLNR), with and without lymphatic microsurgical preventive healing approach (LYMPHA), in a node-positive breast cancer population. We found that the addition of LYMPHA to both ALND or ALND with RLNR is more cost-effective. Objective: This manuscript is the first to employ rigorous methodological criteria to critically appraise a surgical preventative technique for breast cancer-related lymphedema from a cost-utility standpoint. Summary of Background Data: Breast cancer-related lymphedema is a well-documented complication of breast cancer survivors in the US. In this study, we conduct a cost-utility analysis to evaluate the cost-effectiveness of the LYMPHA. Methods: Lymphedema rates after each of the following surgical options: (1) ALND, (2) ALND + LYMPHA, (3) ALND + RLNR, (4) ALND + RLNR + LYMPHA were extracted from a recently published meta-analysis. Procedural costs were calculated using Medicare reimbursement rates. Average utility scores were obtained for each health state using a visual analog scale, then converted to quality-adjusted life years (QALYs). A decision tree was generated and incremental cost-utility ratios (ICUR) were calculated. Multiple sensitivity analyses were performed to evaluate our findings. Results: ALND with LYMPHA was more cost-effective with an ICUR of $1587.73/QALY. In the decision tree rollback analysis, a clinical effectiveness gain of 1.35 QALY justified an increased incremental cost of $2140. Similarly, the addition of LYMPHA to ALND with RLNR was more cost-effective with an ICUR of $699.84/QALY. In the decision tree rollback analysis, a clinical effectiveness gain of 2.98 QALY justified a higher incremental cost of $2085.00. Conclusions: Our study supports that the addition of LYMPHA to both ALND or ALND with RLNR is the more cost-effective treatment option.

The Postpartum Hemorrhage Patient Safety Bundle Implementation at a Single Institution: Successes, Failures, and Lessons Learned.

OBJECTIVE: In 2015, a multidisciplinary consensus bundle of recommendations for the anticipation and management of postpartum hemorrhage was published. Our goal was to evaluate the successes and failures of our institutional bundle implementation process. STUDY DESIGN: An interdisciplinary committee was created to facilitate bundle implementation. All components of the bundle were addressed with cross-disciplinary teaching between stakeholders on the obstetrics units. Tools were built in the electronic medical record to facilitate bundle components of risk stratification, quantitative blood loss calculation, and stage-based hemorrhage management. Bundle components were individually evaluated for acceptability and sustainability. Overall rates of hemorrhage and transfusion from the periods 1 year before and after bundle implementation were also evaluated. RESULTS: Readiness bundle components were successfully implemented, although simulation drills demonstrated limited sustainability. Recognition components were mixed: risk stratification was successfully and sustainably implemented while quantitative blood loss met resistance and was ultimately discontinued as it did not clinically perform superiorly to estimated blood loss. Among response and reporting elements, patient level support and team debriefing were noted as particular deficiencies in our program. CONCLUSION: The postpartum hemorrhage patient safety bundle provided concrete individual elements, which overall improved the success of a stratified program implementation. Multiple deficiencies in acceptability and sustainability were uncovered during our process, particularly concerns about quantitative blood loss implementation and team communication skills. KEY POINTS: · Supply readiness and protocol development were "quick wins.". · Culture change elements included recognition, response, and communication.. · Dedicated champions and electronic medical record tools improved sustainability.. · Poor acceptability and lack of improved outcomes led to element failure..

A Multimetric Health Literacy Analysis of Online Information for Gluteal Augmentation With Fat Grafting.

BACKGROUND AND OBJECTIVES: According to the American Society of Plastic Surgeons the number of gluteal augmentations with fat grafting, colloquially known as the "Brazilian buttock lift" (BBL), doubled from 2014 to 2018. Recent studies have demonstrated that gluteal augmentation with fat grafting has a higher mortality rate when compared with other esthetic surgeries. We hypothesize that online patient-directed information for gluteal augmentation are overly complex, written at an elevated reading grade level, with incomplete or no information regarding associated surgical risks. OBJECTIVE: To perform an objective appraisal of the most popular online patient education materials for gluteal augmentation surgery and explore potential interventions for improving material quality. METHODS: An online Google search using the term "Brazilian butt lift" was performed and the top 10 websites providing relevant information were identified. Readability for each website was determined using Readability Studio. Understandability, actionability and cultural sensitivity was assessed with validated tools by 2 independent raters. RESULTS: The top 10 websites were written at a mean reading grade level of 13.0, appropriate for a high school graduate. No website was written at the American Medical Association and the National Institutes of Health recommended 6th to 8th grade reading level. Mean understandability and actionability scores of 51% and 18.9%, respectively, suggest significant room for improvement. The average cultural sensitivity assessment tool score was 2.30, below the recommended threshold for acceptability of 2.5. Ninety percent of all websites did not meet the threshold for cultural acceptability. CONCLUSIONS: Online patient education materials for gluteal augmentation with fat grafting were written at an inappropriately elevated reading grade level and were overly complex, did not promote reader action, and were not sensitive to the needs of the target demographic.
