Immediate lymphatic reconstruction: Lessons learned over eight years.

Immediate lymphatic reconstruction (ILR) is recognized as a surgical approach used to reduce the risk of developing secondary lymphedema, and evidence demonstrating the efficacy of ILR is favorable. Our Lymphatic Center has become a centralized location offering ILR for the risk-reduction in breast cancer-related lymphedema (BCRL) in New England. Over the course of our experience, we made several modifications and adapted our approach to enhance the operative success of this procedure. These include advancements in our use of indocyanine green (ICG) imaging to identify baseline lymphatic anatomical variation, utilization of fluorescein isothiocyanate for lymphatic vessel visualization, application of the lymphosome concept to guide arm injection sites, verification of anastomotic patency (using ICG), localization of reconstruction to guide radiation therapy, incorporation of intraoperative tools to facilitate better anatomic visualization of the axilla, and addition of a lower extremity vein graft to mitigate venous-related complications. Collecting information from each surgery in a standardized manner, including intraoperative lymphatic channel measurements, and deploying clips for possible future radiation exposure, enables future studies on ILR patient outcomes. In this contribution, we aimed to share our institutional modifications with the surgical community to facilitate further adoption, conversation, and advancement of ILR for the risk-reduction in BCRL.

Development of "Explore Plastic Surgery": An Educational Program for Medical Students Without Home Residency Programs.

BACKGROUND: Medical students who attend institutions without plastic surgery residency programs are at a disadvantage in the plastic surgery match. We developed an educational program for medical students without home programs called Explore Plastic Surgery to provide an overview of the steps toward a career in plastic surgery. The purpose of this study was to assess the impact, utility, and success of the novel program. METHODS: Pre- and postevent surveys were distributed to participants. Survey data were analyzed including participant demographics, perceptions of barriers unique to those without home programs, and the overall event utility. RESULTS: Two hundred seventeen students registered for the program. Ninety-five participants completed the pre-event survey (44%), and of those, 57 participants completed the post-event survey (60%). There was an increase in understanding of the steps toward a career in plastic surgery ( P < 0.001), confidence in overcoming barriers ( P = 0.005), and level of comfort in reaching out to faculty for opportunities ( P = 0.01). There was a decrease in the perceived negative impact that attending medical schools without a home program will have on their abilities to pursue careers in plastic surgery ( P = 0.006). CONCLUSIONS: After the event, participants demonstrated an increase in their confidence in overcoming barriers and a decrease in their perceptions that attending an institution without a home program would negatively impact their ability to pursue plastic surgery. Initiatives focused on early exposure and recruitment of medical students may be important to promote accessibility and diversity within plastic surgery.

Patient-Reported Outcomes on Subjective Nipple Sensation After Double-Incision and Periareolar Mastectomy for Chest Masculinization: Subjective Nipple Sensation After Chest Masculinization.

ABSTRACT: We evaluated patient-reported outcomes to assess for patient and procedural factors associated with postchest masculinization subjective nipple sensation. Patients who underwent double-incision or periareolar mastectomies for chest masculinization by a single senior surgeon (2015-2019) were surveyed at 2 time points regarding postoperative nipple sensation and satisfaction, including patient-reported outcomes using BODY-Q modules (Q-Portfolio.org). Demographic, operative, and postoperative variables were obtained from medical records. Patients were stratified according to survey responses. Univariate and multivariate analyses were performed.Response rate was 42% for survey 1 and 22% for survey 2. Of the 151 survey 1 responders, 138 (91.4%) received double-incision mastectomies and 13 (8.6%) received periareolar mastectomies. Among Survey 1 responders, 84.6% periareolar patients and 69.6% double-incision patients reported "completely" or "a little" nipple sensation preservation, and the difference trended toward significance (P = 0.0719). There was a stepwise increase in proportion of patients reporting sensation with greater recovery time until response to survey 1. Obesity (P = 0.0080) and greater tissue removed (P = 0.0247) were significantly associated with decreased nipple sensation. Nipple satisfaction scores were significantly higher for patients reporting improved nipple sensation (P = 0.0235). Responders to survey 2 who reported greater satisfaction with nipple sensation were significantly more likely to report preserved sensitivity to light touch (P = 0.0277), pressure (P = 0.0046), and temperature (P = 0.0031). Preserved erogenous sensation was also significantly associated with greater satisfaction (P = 0.0018).In conclusion, we found that nipple sensation may be associated with postoperative nipple satisfaction. Operative techniques to optimize nipple sensation preservation may improve this population's postoperative satisfaction.

Air Versus Saline in Tissue Expanders: A Systematic Review of the Literature.

BACKGROUND: There has been a greater focus in recent literature proposing air to be a superior medium to saline in tissue expanders. This study aims to review the literature and assess the quality of data on the efficacy and safety of air as an alternative medium to saline in tissue expanders, in the setting of postmastectomy two-stage reconstruction. METHODS: A systematic review regarding air inflation of tissue expanders was conducted using PubMed, Embase, Cochrane Library, and Web of Science. The methods followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three reviewers separately performed data extraction and comprehensive synthesis. RESULTS: A total of 427 articles were identified in our search query, of which 11 met the inclusion criteria. Three pertained to inflation with room air, and eight pertained to inflation with CO2 using the AeroForm device. They were comparable to decreased overall complication rates in the room air/CO2 cohort compared to saline, although statistical significance was only observed in one of five two-arm studies. Investigating specific complications in the five two-arm studies, significantly lower rates of skin flap necrosis were only observed in two CO2-based studies. Studies rarely discussed other safety profile concerns, such as the impacts of air travel, radiation planning, and air extravasation beyond descriptions of select patients within the cohort. CONCLUSION: There is insufficient evidence to suggest improved outcomes with room air inflation of tissue expanders. Further work is needed to fully characterize the benefits and safety profiles of air insufflation before being adopted into clinical practice.

Does Frailty Predict Outcomes in Patients Undergoing Free or Pedicled Flap Procedures for Lower Extremity Limb Salvage? An Analysis of the American College of Surgeons National Surgical Quality Improvement Program Database.

BACKGROUND: Older and frailer patients are increasingly undergoing free or pedicled tissue transfer for lower extremity (LE) limb salvage. This novel study examines the impact of frailty on postoperative outcomes in LE limb salvage patients undergoing free or pedicled tissue transfer. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2010-2020) was queried for free and pedicled tissue transfer to the LE based on Current Procedural Terminology and the International Classification of Diseases9/10 codes. Demographic and clinical variables were extracted. The five-factor modified frailty index (mFI-5) was calculated using functional status, diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension. Patients were stratified by mFI-5 score: no frailty (0), intermediate frailty (1), and high frailty (2 + ). Univariate analysis and multivariate logistic regression were performed. RESULTS: In total, 5,196 patients underwent free or pedicled tissue transfer for LE limb salvage. A majority were intermediate (n = 1,977) or high (n = 1,466) frailty. High frailty patients had greater rates of comorbidities-including those not in the mFI-5 score. Higher frailty was associated with more systemic and all-cause complications. On multivariate analysis, the mFI-5 score remained the best predictor of all-cause complications-with high frailty associated with 1.74 increased adjusted odds when compared with no frailty (95% confidence interval: 1.47-2.05). CONCLUSION: While flap type, age, and diagnosis were independent predictors of outcomes in LE flap reconstruction, frailty (mFI-5) was the strongest predictor on adjusted analysis. This study validates the mFI-5 score for preoperative risk assessment for flap procedures in LE limb salvage. These results highlight the likely importance of prehabilitation and medical optimization prior to limb salvage.

Which Groups of Plastic Surgery Patients Are Impacted by Social Media Use? An In-Depth Review of Social Media Engagement.

BACKGROUND: Empowerment is the process by which patients gain greater control of their health through active and informed decision-making. Greater patient empowerment has been shown to be positively correlated with improved health care outcomes and experiences. It is unclear how social media affect plastic and reconstructive surgery (PRS) patients' health care decision-making. This study aimed to help quantify how social media sites influence levels of PRS patient empowerment. METHODS: In this cross-sectional study, a modified Cyber Info-Decisional Empowerment Scale (CIDES) survey was distributed through Amazon Mechanical Turk (MTurk) to US adults. Sociodemographic characteristics, PRS history, and social media usage data were collected. Wilcoxon signed-rank and Kruskal-Wallis tests were used to assess for heterogeneity for categorical variables. ANOVA and t tests were used to evaluate differences in means for Likert scale-based responses. RESULTS: A total of 473 survey responses were included. The participants were grouped based on their surgical history: cosmetic [187 (39.5%)], reconstructive [107 (22.6%)], both cosmetic and reconstructive [36 (7.6%)], or non-PRS [143 (30.2%)]. There was increased empowerment depending on the online resources used. Social media use was associated with significantly greater empowerment in six of seven CIDES categories. Of the social media platforms, Facebook was associated with higher empowerment in three of seven CIDES categories. CONCLUSION: Social media use appears to have a positive impact on PRS patient empowerment, which may reflect better patient decision-making and autonomy when consulting with their plastic surgeon.

Edematous Dermal Thickening on Magnetic Resonance Imaging as a Biomarker for Lymphatic Surgical Outcomes.

Background and Objectives: One of the surgical treatments for breast cancer-related lymphedema (BCRL) is debulking lipectomy. The aim of this study is to investigate whether dermal thickness could be utilized as an objective indicator of post-operative changes following debulking. Materials and Methods: A retrospective review of BCRL patients who underwent debulking lipectomy was conducted. MRI-based dermal thickness was measured by two separate trained readers at 16 regions of the upper extremity. Pre- and post-operative reduction in dermal thickness was compared across the affected and unaffected (control) arms for each patient. The Wilcoxon rank sum test was used to assess for significant change. Univariate linear regression was used to assess the relationship between dermal thickness reduction and changes to LYMPH-Q scores, L-Dex scores, and relative volume change. Results: Seventeen patients were included in our analysis. There was significant reduction in dermal thickness at 5/16 regions in the affected arm. Dermal thickness change was significantly correlated with LYMPH-Q scores, L-Dex scores, and relative volume change in 2/16 limb compartments. There was predominant dermal thickening in the dorsal compartment of the upper arm and in the ventral and ulnar compartments of the forearm. Conclusions: Dermal thickness shows promising utility in tracking post-operative debulking procedures for breast cancer-related lymphedema. Further studies with larger patient populations and a variety of imaging modalities are required to continue to develop a clinically objective and reproducible method of post-surgical lymphedema staging and monitoring.

The Effect of Preoperative Diagnosis of Depression and/or Anxiety on Patient-Reported Outcomes Following Chest Wall Masculinization Surgery.

BACKGROUND: Individuals with gender dysphoria have disproportionately high rates of depression and anxiety compared to the cisgender population. Although the benefits of gender affirmation surgery have been well documented, it is unclear whether depression and anxiety affect postoperative patient-reported outcomes (PRO). OBJECTIVES: The authors evaluated the impact of preoperative anxiety or depression on clinical and PRO in patients undergoing chest masculinization surgery. METHODS: Patients who underwent chest masculinization surgery within a 5-year period were reviewed. Demographics and clinical variables were abstracted from medical records. PRO of chest, nipple, and scar satisfaction were obtained postoperatively with the BODY-Q. Groups were stratified by preoperative anxiety, preoperative depression, both, or no history of mental health diagnosis. Univariate and multivariate analyses were performed. RESULTS: Of 135 patients with complete survey responses, 10.4% had anxiety, 11.9% depression, 20.7% both diagnoses, and 57.0% no diagnosis. Clinical data and outcomes were similar. Patients with preoperative depression correlated with lower satisfaction scores for scar appearance (P = .006) and were significantly more likely to report feelings of depression postoperatively (P = .04). There were no significant differences in chest or nipple satisfaction among groups. CONCLUSIONS: Although anxiety and depression are prevalent in gender minorities, we found no association with postoperative clinical outcomes. Patients with preoperative depression were more likely to report lower satisfaction with scar appearance and feelings of depression postoperatively. However, there were no differences in chest or nipple satisfaction. These results highlight the importance of perioperative mental health counseling but also suggest that patients can be satisfied with their results despite a coexisting mental health diagnosis.

Non-Linear Lymphatic Anatomy in Breast Cancer Patients Prior to Axillary Lymph Node Dissection: A Risk Factor For Lymphedema Development.

Immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection (ALND) has become increasingly utilized for the prevention of breast cancer related lymphedema. Preoperative indocyanine green (ICG) lymphography is routinely performed prior to an ILR procedure to characterize baseline lymphatic anatomy of the upper extremity. While most patients have linear lymphatic channels visualized on ICG, representing a non-diseased state, some patients demonstrate non-linear patterns. This study aims to determine potential inciting factors that help explain why some patients have non-linear patterns, and what these patterns represent regarding the relative risk of developing postoperative breast cancer related lymphedema in this population. A retrospective review was conducted to identify breast cancer patients who underwent successful ILR with preoperative ICG at our institution from November 2017-June 2022. Among the 248 patients who were identified, 13 (5%) had preoperative non-linear lymphatic anatomy. A history of trauma or surgery of the affected limb and an increasing number of sentinel lymph nodes removed prior to ALND appeared to be risk factors for non-linear lymphatic anatomy. Furthermore, non-linear anatomy in the limb of interest was associated with an increased risk of postoperative lymphedema development. Overall, non-linear lymphatic anatomy on pre-operative ICG lymphography appears to be a risk factor for developing ipsilateral breast cancer-related lymphedema. Guided by the study's findings, when breast cancer patients present with baseline non-linear lymphatic anatomy, our institution has implemented a protocol of prophylactically prescribing compression sleeves immediately following ALND.

Fluid Distribution Patterns in Early-Stage Upper Extremity Lymphedema.

INTRODUCTION: Magnetic resonance imaging (MRI) stage 1 (early stage) upper extremity lymphedema is characterized by fluid infiltration in the subcutaneous tissues that does not exceed 50% of the extremity circumference at any level. The spatial fluid distribution in these cases has not been detailed and may be important to help determine the presence and location of compensatory lymphatic channels. The aim of this study is to determine whether there was a pattern of distribution of fluid infiltration in patients with early-stage lymphedema that could correspond to known lymphatic pathways in the upper extremity. METHODS: A retrospective review identified all patients with MRI stage 1 upper extremity lymphedema who were evaluated at a single lymphatic center. Using a standardized scoring system, a radiologist graded the severity of fluid infiltration at 18 anatomical locations. A cumulative spatial histogram was then created to map out regions where fluid accumulation occurred most and least frequently. RESULTS: Eleven patients with MRI stage 1 upper extremity lymphedema were identified between January 2017 and January 2022. The mean age was 58 years and the mean BMI was 30 m/kg2. One patient had primary lymphedema and the remaining 10 had secondary lymphedema. The forearm was affected in nine cases, and fluid infiltration was predominantly concentrated along the ulnar aspect, followed by the volar aspect, while the radial aspect was completely spared. Within the upper arm, fluid was primarily concentrated distally and posteriorly, and occasionally medially. CONCLUSIONS: In patients with early-stage lymphedema, fluid infiltration is concentrated along the ulnar forearm and the posterior distal upper arm, which aligns with the tricipital lymphatic pathway. There is also sparing of fluid accumulation along the radial forearm in these patients, suggesting a more robust lymphatic drainage along this region, possibly due to a connection to the lateral upper arm pathway.

Quantifying radiation in the axillary bed at the site of lymphedema surgical prevention.

PURPOSE: Immediate lymphatic reconstruction (ILR) is a procedure known to reduce the risk of lymphedema in patients undergoing axillary lymph node dissection (ALND). However, patients who receive adjuvant radiotherapy are at increased risk of lymphedema. The aim of this study was to quantify the extent of radiation at the site of surgical prevention. METHODS: We recently began deploying clips at the site of ILR to identify the site during radiation planning. A retrospective review was performed to identify breast cancer patients who underwent ILR with clip deployment and adjuvant radiation therapy from October 2020 to April 2022. Patients were excluded if they had not completed radiotherapy. The exposure and dose of radiation received by the site was determined and recorded. RESULTS: In a cohort of 11 patients, the site fell within the radiation field in 7 patients (64%) and received a median dose of 4280 cGy. Among these 7 patients, 3 had sites located within tissue considered at risk of oncologic recurrence and the remaining 4 sites received radiation from a tangential field treating the breast or chest wall. The median dose to the ILR site for the 4 patients whose sites were outside the radiation fields was 233 cGy. CONCLUSION: Our findings suggest that even when the site of surgical prevention was not within the targeted radiation field during treatment planning, it remains susceptible to radiation. Strategies for limiting radiation at this site are needed.

A Prospective Study of Radiation Therapy After Immediate Lymphatic Reconstruction: Analysis of the Dosimetric Implications.

PURPOSE: Axillary lymph node dissection (ALND) and regional nodal irradiation (RNI) are the primary causes of breast cancer-related lymphedema (BCRL). Immediate lymphatic reconstruction (ILR) is a novel surgical procedure that reduces the incidence of BCRL after ALND. The ILR anastomosis is placed in a location thought to be outside the standard radiation therapy fields to prevent radiation-induced fibrosis of the reconstructed vessels; however, there is excess risk of BCRL from RNI even after ILR. The purpose of this study was to understand the radiation dose distribution in relation to the ILR anastomosis. METHODS AND MATERIALS: This prospective study included 13 patients treated with ALND/ILR from October 2020 to June 2022. A twirl clip deployed during surgery was used to identify the ILR anastomosis site during radiation treatment planning. All cases were planned using a 3D-conformal technique with opposed tangents and an obliqued supraclavicular (SCV) field. RESULTS: RNI deliberately targeted axillary Levels 1 to 3 and the SCV nodal region in 4 patients and was limited to Level 3 and SCV nodes in 9 patients. The ILR clip was located in Level 1 in 12 patients and Level 2 in 1 patient. In patients with radiation directed at only Level 3 and SCV, the ILR clip was still within the radiation field in 5 of these patients and received a median dose of 3939 cGy (range, 2025-4961 cGy). The median dose to the ILR clip was 3939 cGy (range, 139-4961 cGy) for the entire cohort. The median dose was 4275 cGy (range, 2025-4961 cGy) when the ILR clip was within any radiation field and 233 cGy (range, 139-280 cGy) when the clip was outside all fields. CONCLUSION: The ILR anastomosis was often directly irradiated with 3D-conformal techniques and received substantial radiation dose, even when the site was not deliberately targeted. Long-term analysis will help determine whether minimizing radiation dose to the anastomosis will decrease BCRL rates.

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.

Tracking Symptoms of Patients With Lymphedema Before and After Power-Assisted Liposuction Surgery.

PURPOSE: Lymphedema negatively impacts patients from a psychosocial standpoint and consequently affects patient's quality of life. Debulking procedures using power-assisted liposuction (PAL) are currently deemed an effective treatment for fat-dominant lymphedema and improves anthropometric measurements as well as quality of life. However, there have been no studies specifically evaluating changes in symptoms related to lymphedema after PAL. An understanding of how symptoms change after this procedure would be valuable for preoperative counseling and to guide patient expectations. METHODS: A cross-sectional study was performed in patients with extremity lymphedema who underwent PAL from January 2018 to December 2020 at a tertiary care facility. A retrospective chart review and follow-up phone survey were conducted to compare signs and symptoms related to lymphedema before and after PAL. RESULTS: Forty-five patients were included in this study. Of these, 27 patients (60%) underwent upper extremity PAL and 18 patients (40%) underwent lower extremity PAL. The mean follow-up time was 15.5±7.9 months. After PAL, patients with upper extremity lymphedema reported having resolved heaviness (44%), as well as improved achiness (79%) and swelling (78%). In patients with lower extremity lymphedema, they reported having improved all signs and symptoms, particularly swelling (78%), tightness (72%), and achiness (71%). CONCLUSIONS: In patients with fat-dominant lymphedema, PAL positively impacts patient-reported outcomes in a sustained fashion over time. Continuous surveillance of postoperative studies is required to elucidate factors independently associated with the outcomes found in our study. Moreover, further studies using a mixed method approach will help us better understand patient's expectations to achieve informed decision and adequate treatment goals.

Omental vascularized lymph node transplant for the treatment of breast lymphedema: A case report.

Breast lymphedema is a type of breast cancer related lymphedema that leads to significant discomfort and negative impact on body image. Conservative therapy and lymphovenous bypass have been previously described as possible treatment methods for breast lymphedema, however, a unified approach to treatment is lacking. The current report describes a case of breast lymphedema successfully treated with vascularized lymph node transfer (VLNT) after failed attempt at management with conservative therapy. The patient is a 48-year-old female with right-sided breast cancer who underwent breast conservation therapy in 2015 and subsequently developed pain and swelling of the right breast. The diagnosis of breast lymphedema was supported by clinical evaluation as well as MRI, lymphoscintigraphy, and lymphography. In consultation with a breast surgeon, breast lymphedema was determined not to be an indication for mastectomy. The patient was offered and underwent an omental VLNT to the right breast. A 20 cm segment of omentum with associated gastroepiploic vessels and lymph nodes was harvested, transferred to the right axilla and gastroepiploic vessels were anastomosed to the recipient thoracodorsal vessels. The patient tolerated the procedure well and there were no complications. Additional donor sites were considered, such as the groin and submental regions, but an omental flap was favored in this case because of the lower risk of donor site lymphedema. In the years following, the patient reported significant improvement in symptoms as well as objective reduction of edema on MRI. We propose the consideration of VLNT for breast lymphedema refractory to other methods of management.
