Sizing-Up a Novel Medial Thigh Flap: A Comprehensive Volumetric Analysis of the Chimeric Gracilis and Profunda Artery Perforator Flap.

BACKGROUND: The presence of a chimeric gracilis and profunda artery perforator (PAP) flap with a common arterial pedicle has been demonstrated on computed tomography angiography (CTA) in up to 59% of patients and confirmed in a cadaveric model1,2. Already utilized for head & neck reconstruction by Heredero et al., this novel flap could provide more volume than either flap alone which is advantageous, particularly in patients with sizable defects.3 The purpose of this study was to determine the average tissue volume that can be utilized from this chimeric flap. METHODS: CT Angiogram imaging studies exhibiting chimeric flap anatomy were reviewed over a 7 year period at a single institution utilizing Visage Version 7.1, a radiology picture archiving and communication system (PACS). This software was used to trace the flap pedicles and to capture estimated soft tissue volumes of each respective flap. RESULTS: A total of 31 patients, consisting of 52 lower extremity gracilis and PAP chimeric flaps, underwent tissue volume analysis. The average total volume of soft tissue supplied by the gracilis flap was found to be 70.21 cm3 (SD=26.99). The average volume of the PAP flap was 31.73 cm3 (SD=26.12). The average total volume captured by the chimeric gracilis and PAP flap was 101.94 cm3 (SD=62.40). CONCLUSION: The potential soft tissue volume that can be harvested from a chimeric gracilis and PAP flap is significantly greater than solitary gracilis or PAP flaps. This chimeric flap may serve as a viable and advantageous reconstructive option for patients requiring large volume soft tissue coverage, particularly if other sizable options are not available.

The PUG Flap: Conjoined Profunda Artery Perforator and Upper Gracilis Flap for Breast Reconstruction.

Abdominal-based free flaps are the mainstay of autologous breast reconstruction; however, the region may not be ideal for patients with inadequate soft tissue or history of abdominal surgery. This case describes the use of a novel conjoined flap based on the profunda artery perforator and upper gracilis pedicles, named the perforator and upper gracilis (PUG) flap. This flap design aims to maximize medial thigh flap volume while ensuring robust tissue perforation. Here, we present our experience with the PUG flap in a breast cancer patient undergoing autologous reconstruction. The patient was a 41-year-old woman seeking nipple-sparing mastectomy and immediate autologous reconstruction with the PUG flap due to limited abdominal tissue availability. The gracilis and profunda artery perforator flaps were elevated using one boomerang-style skin paddle. Once harvested, the flaps were inset with antegrade and retrograde flow off the internal mammary arteries and both respective internal mammary veins. The donor site was closed in a V-Y pattern resulting in a thigh lift-type lift and concealed scar. In conclusion, the boomerang-style PUG flap maximizes medial thigh free tissue transfer volume, offers internal blood flow redundancy, and maintains good cosmesis of the donor site.

Patient Perspectives and Quality of Life after Breast Reconstruction and the Impact of Subsequent Revisions.

There is limited research on the impact of revisional surgery after breast reconstruction on patient experience and postoperative quality of life (QoL). Methods: Patients undergoing mastectomy with immediate implant-based or autologous free-flap breast reconstruction from 2008 to 2020 were reviewed. These patients were categorized by revisions (0-1, 2-3, and 4+) and surveyed on QoL metrics using BREAST-Q and Was It Worth It? (WIWI) questionnaires. BREAST-Q QoL, satisfaction, and WIWI metrics between revision groups were evaluated. Results: Among 252 patients, a total of 150 patients (60%) underwent zero to one revisions, 72 patients (28%) underwent two to three revisions, and 30 patients (12%) underwent four or more revisions. Median follow-up was 6 years (range, 1-11 years). BREAST-Q satisfaction among patients with four or more revisions was significantly lower (P = 0.03), while core QoL domains (chest physical, psychosocial, and sexual well-being) did not significantly differ. Analysis of unplanned reoperations due to complications and breast satisfaction showed no significant difference in QoL scores between groups (P = 0.08). Regarding WIWI QoL metrics, four or more revisions were associated with a higher rate of worse QoL (P = 0.035) and worse overall experience (P = 0.001). Most patients in all revision groups felt it was worthwhile to undergo breast reconstruction (86%), would choose breast reconstruction again (83%), and would recommend breast reconstruction to others (79%). Conclusions: Overall, a majority of patients undergoing revisions after breast reconstruction still have a worthwhile experience. Although reoperations after breast reconstruction do not significantly impact long-term BREAST-Q QoL domains, patients undergoing four or more revisions have significantly lower breast satisfaction, worse QoL, and a postoperative experience worse than expected.

Outcomes of Lymphovenous Anastomosis for Lower Extremity Lymphedema: A Systematic Review.

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.

Long-term breast and nipple sensation after nipple-sparing mastectomy with implant reconstruction: Relevance to physical, psychosocial, and sexual well-being.

BACKGROUND: The effect of postoperative sensation on quality-of-life (QoL) following nipple-sparing mastectomy (NSM) with implant-based reconstruction is not well described. We evaluated the impact of breast and nipple sensation on patient QoL by using BREAST-Q. METHODS: Patients undergoing NSM with implant reconstruction from 2008 to 2020 were mailed a survey to characterize their postoperative breast and nipple sensation. BREAST-Q metrics were compared between totally numb patients and those with sensation. RESULTS: A total of 349 patients were included. Overall, 131 (38%) responded; response rates regarding breast and nipple sensation were 36% (N = 124/349) and 34% (N = 117/349). Median time from surgery to survey completion was 6 years. The majority had bilateral procedures (101, 77%), including direct-to-implant (99, 76%) and tissue expander (32, 24%) reconstruction. Regarding breast sensation, the majority of patients reported their reconstructed breasts as totally numb (47, 38%) or much less sensation than before surgery (59, 48%). Regarding nipple sensation, the majority of patients reported their nipples were totally numb (67, 57%) or had much less sensation than before surgery (37, 32%). Total numbness of reconstructed breasts resulted in a significantly lower chest physical well-being (mean score: 73.5 vs. 81.2, respectively, P = 0.048). Total numbness of postoperative nipple(s) resulted in significantly lower chest physical (mean score: 74.8 vs. 85.2, respectively, P = 0.007), psychosocial (mean score 77.4 vs. 84.4, respectively, P = 0.041), and sexual well-being (mean score: 55.7 vs. 68.3, respectively, P = 0.002). CONCLUSIONS: Long-term breast and nipple sensation are significantly diminished after NSM with implant reconstruction. Patients with preserved sensation experience better physical, psychosocial, and sexual well-being.

Chest wall resection for breast cancer: 21st century Mayo clinic experience.

BACKGROUND: We hypothesized full-thickness chest wall resection (FTCWR) with advanced surgical techniques and modern systemic therapy is safe, provides local control, and good overall survival. METHODS: Retrospective review of FTCWR (including rib or part of sternum) for breast cancer between 2000 and 2020. Primary endpoints included 90-day morbidities and all-cause mortality. Secondary endpoints were loco-regional and distant recurrence, DFS and overall survival (OS). RESULTS: A total of 35 patients met the criteria. 34 FTCWR were for recurrence and the median time to chest wall recurrence was 6 years. Tumor subtype was triple-negative in 51% and the remainder HR+ Her2-. 58% were palliative resections. FTCWR included rib(s) in 89% and portion of sternum in 57%; 94% required reconstruction and 80% were R0 resections. There were no 90-day mortalities. Overall morbidity was 10/35(28%). 17(49%) patients received neoadjuvant systemic therapy for their recurrence and three received neoadjuvant radiation. Adjuvant treatment included chemotherapy (8), endocrine therapy (3), and both (8). Ten patients (28%) received adjuvant radiation. The Median follow-up was 31 months and there were 6 (17%) loco-regional and 7 (20%) distant recurrences. OS was 86% and 67% at 1 and 3 years, respectively. CONCLUSION: FTCWR was associated with low morbidity, mortality, recurrence rates, and good OS. Selective FTCWR is safe and has acceptable short-term survival rates.

The Effects of Website and Social Media Presence of Integrated Plastic Surgery Residency Programs on Prospective Applicants: An Analysis During the Coronavirus Disease 2019 Pandemic.

PURPOSE: Integrated plastic surgery residency programs have increased their social media presence to educate and recruit prospective residents. This study aims to understand the impact of integrated plastic surgery residency program social media on the 2020 to 2021 applicants' evaluation of prospective programs, particularly during the coronavirus disease 2019 pandemic. MATERIALS AND METHODS: An optional 20-item online survey was sent to integrated plastic surgery residency applicants applying to the authors' program. RESULTS: Surveys were sent to 300 integrated plastic surgery residency applicants with an average of 168 responses (56% response rate). Social media resources included official residency program website (87.1%), Instagram (70.2%), and Doximity (46.8%). The most frequently used resource by applicants was the official residency program website (43.9%); Instagram was the second most frequently used (40.2%) followed by Doximity (8.3%). Most respondents agreed that social media was an effective means to inform applicants (66.1%), and it positively impacted their perception of the program (64.8%). The cited benefits were helping the program exhibit its culture and comradery among residents, faculty, and staff (78.4%). Among applicants, 73.6% noted that it had a significant impact on their perceptions of programs. Most respondents truncated their planned plastic surgery subinternships, completing 1 instead of 3 planned subinternships because of coronavirus disease 2019 limitations. CONCLUSIONS: During the 2020 to 2021 plastic surgery application cycle, applicants used social media accounts of plastic surgery residency programs to inform and educate themselves about prospective programs. This study suggests that investing resources into a social media residency accounts is a meaningful pursuit for integrated plastic surgery programs and is an important aspect in today's recruitment.

Seldom one and done: Characterizing rates of reoperation with direct-to-implant breast reconstruction after mastectomy.

BACKGROUND: Limited data exist outlining reoperations after direct-to-implant (DTI), tissue expander (TE) and autologous free-flap breast reconstruction. METHODS: Patients undergoing mastectomy with reconstruction from 2008 to 18 were reviewed. Patient factors, surgical techniques, planned, unplanned, and total reoperations were analyzed. RESULTS: Among 544 total patients, the majority underwent DTI (294, 54%) or TE (176, 32%); 74 (14%) received autologous free-flaps. Majority of DTI patients (55%) underwent subsequent reoperations. Compared to autologous tissue, DTI had less patients undergo additional surgery (76% vs. 55%, P = 0.001). Incidence of total unplanned reoperations did not significantly differ between reconstructive groups. The rate of unplanned reoperations due to complications was lowest for DTI (39%) when compared to TE (48%) and autologous (55%, P = 0.015). Compared to TE, DTI carried a lower risk for ≥2 total reoperations (OR = 0.21, 95% CI 0.13-0.33, P < 0.001). CONCLUSIONS: Seldom "one and done," additional surgery after DTI remains significant.

Diagnosis of Primary Scrotal Lymphedema Using 99mTc-Sulfur Colloid Lymphoscintigram: Correlation With MR Lymphangiogram.

ABSTRACT: We report a case of a 19-year-old man who presented with severe scrotal swelling. His medical history was notable for severe global edema at birth. Most areas of swelling had resolved by adolescence with exception of the scrotum and the left lower extremity. 99mTc-filtered sulfur colloid lymphoscintigraphy of the lower extremities demonstrated prominent dermal backflow into the superficial scrotum and thighs, which were confirmed on the SPECT/CT images, and correlated with findings on MR lymphangiogram. Lymphoscintigram and MR lymphangiogram may provide complementary information to aid diagnosis and management of primary scrotal lymphedema.

Procedural Trends in Medicare Reimbursement and Utilization for Breast Reconstruction: 2000-2019.

PURPOSE: Development of appropriate reimbursement models for breast reconstruction in the United States requires an understanding of relevant economic trends. The purpose of this study is to evaluate longitudinal patterns in Medicare reimbursement for frequently performed breast reconstruction procedures between 2000 and 2019. METHODS: Reimbursement data for 15 commonly performed breast reconstruction procedures were analyzed using the Centers for Medicare & Medicaid Services Physician Fee Schedule Look-Up Tool for each Current Procedural Terminology code. By utilizing changes to the US consumer price index, monetary data were adjusted for inflation to 2019 US dollars. Inflation-adjusted trends were used to calculate average annual and total percentage changes in reimbursement over time. RESULTS: From 2000 to 2019, average adjusted reimbursement for all procedures fell by 13.32%. All procedures demonstrated a negative adjusted reimbursement rate other than immediate insertion of breast prosthesis, which increased by 55.37%. The largest mean decrease was observed in breast reconstruction with other technique (-28.63%), followed by single pedicle transverse rectus abdominis myocutaneous flap (-26.02%), single pedicle transverse rectus abdominis myocutaneous flap with microvascular anastomosis (-23.33%), latissimus dorsi flap (-19.65%), and free flap reconstruction (-19.36%). CONCLUSIONS: There has been a steady yet substantial decline in Medicare reimbursement for the majority of breast reconstruction procedures over the last 20 years. Given increasing medical costs and the financial uncertainty of the US health care system, an understanding of Medicare reimbursement trends is vital for policymakers, administrators, and physicians to develop agreeable reimbursement models that facilitate growth and economic vitality of breast reconstruction in the United States.

Formative Feedback with In-Class Question Bank Utilization Improves Resident Satisfaction with General Surgery Didactics.

BACKGROUND: Formative feedback provides low-stakes opportunities for educational improvement. To enrich our basic science didactics, formative feedback measures were incorporated into our didactics using mobile devices. MATERIALS AND METHODS: Lecture changes included institutional paid access to a commercial question bank, a 5-item in-class pre-didactic quiz curated from the question bank and taken on the resident's mobile device, and group discussion of quiz topics. An anonymous survey was sent to participating residents. RESULTS: Overall response rate was 71% among residents. All reported that the new lecture format was a valuable addition to the basic science curriculum (100% Agree/Strongly Agree), and formative assessments provided valuable feedback about the progress of their learning (Strongly Agree = 42%, Agree =58%). All residents reported that in-class use of their mobile device for quizzes was convenient, with majority (84%) preferring it over paper printouts. Residents were more motivated to study before lecture (Strongly Agree = 42%, Agree =42%), with majority also reporting the new format helped identify weaknesses in their knowledgebase (Strongly Agree = 58%, Agree =33%). While majority of residents agreed that quizzes motivated them to study more after lecture, a large portion disagreed (42%). Majority of senior residents reported that the process of composing quizzes prior to lecture enriched their own learning (57%) and helped them find gaps in their knowledge (71%). CONCLUSION: Incorporating a commercial question bank within didactics gives general surgery residents formative feedback and encourages learning outside the classroom, leading to improved satisfaction with basic science didactics.

The Goldilocks Procedure with and without Implant-Based Immediate Breast Reconstruction in Obese Patients: The Mayo Clinic Experience.

BACKGROUND: Obesity is a risk factor for complications in breast reconstruction. Thus, implant-based immediate breast reconstruction in obese women may be controversial. The authors analyzed obese patients who underwent skin-sparing mastectomy using Wise-pattern incisions (Goldilocks procedure) and compared outcomes between two groups: Goldilocks with immediate breast reconstruction and Goldilocks only. METHODS: A retrospective review was performed of patients with a body mass index of 30 kg/m2 or higher who underwent the Goldilocks procedure at the Mayo Clinic Health System from 2012 to 2019. Data were extracted from electronic medical records. Minor complications (partial-thickness wound dehiscence or flap necrosis, or tissue expander/implant malposition) and major complications (full-thickness wound dehiscence or flap necrosis, capsular contracture, tissue expander/implant explantation, or unplanned reoperation or readmission) were compared between groups. Patient-reported outcomes using BREAST-Q questionnaires were also assessed. RESULTS: One hundred five patients (181 breasts) were included. Mean ± SEM age and body mass index were 57.1 ± 10.4 years and 37.9 ± 5.8 kg/m2 for the Goldilocks-only group and 51.5 ± 1.1 years and 35.5 ± 0.4 kg/m2 for the Goldilocks with immediate breast reconstruction group, respectively. Median follow-up time was 15.1 months (interquartile range, 10.0 to 28.6 months). Overall, 96 breasts underwent the Goldilocks-only procedure and 85 Goldilocks with immediate breast reconstruction. Multivariable analyses revealed a higher rate of minor complications (adjusted hazard ratio, 2.83; 95 percent CI, 1.22 to 7.02) and major complications (adjusted hazard ratio, 2.26; 95 percent CI, 1.25 to 4.24) in the Goldilocks with immediate breast reconstruction group compared with the Goldilocks-only group, at any given time. Patient satisfaction was not statistically different between groups. CONCLUSIONS: The Goldilocks procedure is a feasible breast reconstructive option in obese patients; however, when it is performed with immediate breast reconstruction, it is associated with higher rates of complications. For patients with a body mass index of 40 kg/m2 or greater, the authors recommend the Goldilocks-only procedure or delayed reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Unplanned implant removal in locally advanced breast cancer.

Study conducted to determine frequency and timing of unplanned breast implant removal after mastectomy, reconstruction, and postmastectomy radiation (PMRT). From 2010-2017, 52 patients underwent mastectomy, reconstruction, and PMRT. With median follow-up of 3.1 years, 23 patients (44%) experienced implant removal. Implant removal occurred in 9 (17%) patients before starting PMRT and 14 (27%) patients after starting PMRT. Implant removal rates were similar for hypofractionated PMRT compared with standard fractionation and for proton compared with photon PMRT. Implant removal is common for women undergoing mastectomy and reconstruction followed by PMRT. The risk is clinically significant even before starting radiation.

Expanding the Horizon: Single-port Robotic Vascularized Omentum Lymphatic Transplant.

Vascularized omentum lymphatic transplant is frequently used for the treatment of lymphedema due to demonstrated efficacy, a reduced complication profile, and, in particular, negligible risk of donor site lymphedema. Historically harvested by open laparotomy, more recent techniques involve laparoscopic omental harvest. Although effective and reproducible, laparoscopy may be limited by reduced visualization, minimal tactile feedback, multiple port sites, and imprecise instrumentation. Therefore, we employed the da Vinci Single-Port (SP) surgical robot system for vascularized omentum lymphatic transplant. A 52-year-old man with a 3-year history of progressive left lower extremity swelling and lymphoscintigraphy and magnetic resonance lymphangiogram consistent with lymphedema of unknown etiology underwent vascularized omentum lymphatic transplant to the left groin. A 2.5-cm infraumbilical incision was used for placement of the primary trocar, through which the camera and operating instruments were passed. Following robotic harvest, the omental lymph node flap was transferred to the left groin for microsurgical anastomosis. The procedure was uneventful, and the patient was discharged on postoperative day 1. At 6 weeks, there were no complications. Here, we show for the first time the safety and feasibility of robotic omental lymph node flap harvest for extremity lymphedema using the da Vinci Single-Port robotic system. The benefits of this technology include a minimally-invasive approach that allows for flap dissection and removal through a single 2.5-cm incision. Further investigation is necessary to characterize the indications and limitations of this technique in plastic surgery.

Analysis of 20-Year Trends in Medicare Reimbursement for Reconstructive Microsurgery.

BACKGROUND: Microsurgery is being increasingly utilized across surgical specialties, including plastic surgery. Microsurgical techniques require greater time and financial investment compared with traditional methods. This study aimed to evaluate 20-year trends in Medicare reimbursement and utilization for commonly billed reconstructive microsurgery procedures from 2000 to 2019. METHODS: Microsurgical procedures commonly billed by plastic surgeons were identified. Reimbursement data were extracted from The Physician Fee Schedule Look-Up Tool from the Centers for Medicare and Medicaid Services for each current procedural terminology (CPT) code. All monetary data were adjusted for inflation to 2019 U.S. dollars. The average annual and total percentage changes in reimbursement were calculated based on these adjusted trends. To assess utilization trends, CMS physician/supplier procedure summary files were queried for the number of procedures billed by plastic surgeons from 2010 to 2018. RESULTS: After adjusting for inflation, the average reimbursement for all procedures decreased by 26.92% from 2000 to 2019. The greatest mean decrease was observed in CPT 20969 free osteocutaneous flaps with microvascular anastomosis (-36.93%). The smallest mean decrease was observed in repair of blood vessels with vein graft (-9.28%). None of the included procedures saw an increase in reimbursement rate over the study period. From 2000 to 2019, the adjusted reimbursement rate for all procedures decreased by an average of 1.35% annually. Meanwhile, the number of services billed to Medicare by plastic surgeons across the included CPT codes increased by 42.17% from 2010 to 2018. CONCLUSION: This is the first study evaluating 20-year trends in inflation-adjusted Medicare reimbursement and utilization in reconstructive microsurgery. Reimbursement for all included procedures decreased over 20% during the study period, while number of services increased. Increased consideration of these trends will be important for U.S. policymakers, hospitals, and surgeons to assure continued access and reconstructive options for patients.

The Chimeric Gracilis and Profunda Artery Perforator Flap: Characterizing This Novel Flap Configuration with Angiography and a Cadaveric Model.

BACKGROUND: A chimerically configured gracilis and profunda artery perforator (PAP) flap is highly prevalent based on recent computed tomography (CT)-imaging data. The purpose of this study is to further characterize the vascular anatomy of this novel flap configuration and determine the feasibility of flap dissection. METHODS: To characterize flap arterial anatomy, lower extremity CT angiograms performed from 2011 to 2018 were retrospectively reviewed. To characterize venous anatomy and determine the feasibility of flap harvest, the lower extremities of cadavers were evaluated. RESULTS: A total of 974 lower extremity CT angiograms and 32 cadavers were included for the assessment. Of the 974 CT angiograms, majority (966, 99%) were bilateral studies, yielding a total of 1,940 lower extremities (right-lower-extremity = 970 and left-lower-extremity = 970) for radiographic evaluation. On CT angiography, a chimerically configured gracilis and PAP flap was found in 51% of patients (n = 494/974). By laterality, chimeric anatomy was present in 26% of right lower extremities (n = 254/970) and 25% of left lower extremities (n = 240/970); bilateral chimeric anatomy was found in 12% (n = 112/966) of patients. Average length of the common arterial pedicle feeding both gracilis and PAP flap perforasomes was 31.1 ± 16.5 mm (range = 2.0-95.0 mm) with an average diameter of 2.8 ± 0.7 mm (range = 1.3-8.8 mm).A total of 15 cadavers exhibited chimeric anatomy with intact, conjoined arteries and veins allowing for anatomical tracing from the profunda femoris to the distal branches within the tissues of the medial thigh. Dissection and isolation of the common pedicle and distal vessels was feasible with minimal disruption of adjacent tissues. Chimeric flap venous anatomy was favorable, with vena commitante adjacent to the common pedicle in all specimens. CONCLUSION: Dissection of a chimeric medial thigh flap consisting of both gracilis and PAP flap tissues is feasible in a cadaveric model. The vascular anatomy of this potential flap appears suitable for future utilization in a clinical setting.
