The value of microvascular breast reconstruction: Cost equivalence of TRAM and DIEP flaps implications in the era of CMS reforms.

Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction. The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types. A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice. The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

Continuing Insurance Coverage for Flap-Based Breast Reconstruction: Is There a Reservation Cost Related to a Woman's Abdominal Flap Choice?

The recent proposed alterations to the Centers for Medicare and Medicaid Services regulations, although subsequently reversed on August 21, 2023, have engendered persistent concerns regarding the impact of insurance policies on breast reconstruction procedures coverage. This study aimed to identify factors that would influence women's preferences regarding autologous breast reconstruction to better understand the possible consequences of these coverage changes. A survey of adult women in the United States was conducted via Amazon Mechanical Turk to assess patient preferences for breast reconstruction options, specifically deep inferior epigastric perforator (DIEP) and transverse rectus abdominis myocutaneous (TRAM) flap surgery. The Cochrane-Armitage test evaluated trends in flap preferences concerning incremental out-of-pocket payment increases. Of 500 total responses, 485 were completed and correctly answered a verification question to ensure adequate attention to the survey, with respondents having a median (interquartile range) age of 26 (25-39) years. When presented with the advantages and disadvantages of DIEP versus TRAM flaps, 78% of respondents preferred DIEP; however, as DIEP's out-of-pocket price incrementally rose, more respondents favored the cheaper TRAM option, with $3804 being the "indifference point" where preferences for both procedures converged (P < 0.001). Notably, respondents with a personal history of breast reconstruction showed a higher preference for DIEP, even at a $10,000 out-of-pocket cost (P = 0.04). Out-of-pocket cost can significantly influence women's choices for breast reconstruction. These findings encourage a reevaluation of emergent insurance practices that could potentially increase out-of-pocket costs associated with DIEP flaps, to prevent cost from decreasing equitable patient access to most current reconstructive options.

Trunk Muscle Function and Core Stability in Women Who Had Muscle-Sparing Pedicled Transverse Rectus Abdominis Myocutaneous Flap Breast Reconstruction.

The long-term effects of the unilateral muscle-sparing pedicled transverse rectus abdominis myocutaneous (TRAMmsp) flap procedure on trunk muscle performances and core stability were investigated in women with breast cancer. Forty women (mean age = 42.6years) who had received breast reconstruction with the unilateral TRAMmsp flap procedure no less than 6months earlier (mean = 10.3 [SD = 4.9] months) (TRAM group) participated, and 30 women who were healthy and matched for age (mean age = 41.2years) served as controls (control group). Their abdominal and back muscle strength was assessed using the curl-up and prone extension tests, respectively, and their static abdominal muscle endurance and back extensor endurance were assessed using the sit-up endurance test in the crook-lying position and the Biering-Sørensen test, respectively. Core stability strength was assessed using a 4-level limb-lowering test (abdominal muscle test) and core stability endurance was assessed while lying supine with both flexed legs 1 inch off the mat while keeping the pelvis in a neutral position with a pressure biofeedback unit. Compared with the control group, trunk muscles of the TRAM group were weaker, showing less endurance, as were their core stability strength and endurance. Static trunk muscle endurances and trunk flexion strength were associated with core stability in both groups. Women exhibit trunk flexor and extensor weakness along with poor endurance and impaired core stability even after an average of 10months from receiving the TRAMmsp flap procedure. Immobilization after surgery, with possible systemic inflammatory effects from surgery and chemotherapy, might have further contributed to the generalized weakness subsequent to the partial harvesting of the rectus abdominis. Women after breast reconstruction with the TRAMmsp flap procedure show long-lasting deficits of strength and endurance in abdominal muscles, back extensors, and core stability. Proactive measures including early detection and evaluation of impairments as well as timely intervention targeting these clients are important to minimize the dysfunction and support their return to community participation.

The Influence of the Superficial Venous System on DIEP Flap Drainage in Breast Reconstruction.

Autologous tissue has become the gold standard in breast reconstruction. The use of a DIEP flap has the advantages of giving a natural appearance to the reconstructed breast and being associated with lower morbidity at the donor site when compared to the transverse rectus abdominis myocutaneous (TRAM) flap. Venous complications such as venous thrombosis and insufficiency remain the main causes of flap loss and surgical revisions. The aim of this study was to evaluate the influence of superficial venous drainage of the DIEP flap and the addition of a second venous anastomosis have on flap survival. This was a retrospective cohort study collected from a prospective database mantained by our institution. Data was obtained from the medical records of female patients who underwent mastectomy and breast reconstruction with a DIEP flap between March 2010 and March 2017. We evaluated 137 DIEP patients with unilateral breast reconstructions. In 64 (46.7%) the deep venous system was chosen and 73 (53.3%) had an additional superficial vein anastomosed. Out of the 137 patients evaluated, there were 16 (11.67%) cases of revision, 14 (10.21%) were due to venous thrombosis. 12 cases (8.75%) of flap loss were reported. Reoperation rate was lower in the dual venous drainage group when compared to the single venous drainage group (p = 0.005), as was the rate of flap loss (p = 0.006) and reoperation due to venous thrombosis (p = 0.002). Out of the 125 DIEP flaps, fat necrosis was clinically identified in 7 (5.1%) cases, and the rate was lower in the dual venous drainage system group (p = 0.01). Dual venous drainage of a DIEP flap appears to reduce the rates of venous thrombosis, reoperation, total flap loss and fat necrosis.

Prospective Clinical Trial of Premastectomy Radiotherapy Followed by Immediate Breast Reconstruction for Operable Breast Cancer

Radiation delivered prior to mastectomy and autologous breast reconstruction may avoid the adverse effects of radiation on autologous donor tissue while providing the psychologic benefit of immediate reconstruction. We aimed to study the feasibility of premastectomy radiation therapy (PreMRT). A total of 50 women enrolled in a prospective trial of preoperative radiation to the breast and regional nodes followed by mastectomy with axillary evaluation and immediate breast reconstruction. The trial was embedded in a randomized trial of hypofractionated versus conventionally fractionated regional nodal irradiation (NCT02912312). Eligible women enrolled from 2018-22, had cT0-T3 N0-3 breast cancer, and a pre-operative recommendation for radiation. The primary outcome was frequency of complete free flap loss. Mastectomy skin flap necrosis was assessed by validated SKIN grading score. The Satisfaction with Breast Cosmetic Outcomes Scales evaluated patient satisfaction with cosmetic result. Descriptive statistics and 95% exact confidence intervals were calculated. One patient withdrew prior to any treatment and one elected not to have breast reconstruction. Median age of the 48 women completing PreMRT and reconstruction was 48 [range 31-72]. Most had ER-positive HER2-negative (77%), cT3 (54%) or cT2 (38%), cN1 (79%) disease and received 50 Gy in 25 fractions (n = 24) or 40.05 Gy in 15 fractions (n = 23). Four received 10-16 Gy internal mammary or infraclavicular boost. 35% VMAT, 48% matched photon-electron, and 17% partially-wide-tangent technique. Median time to surgery was 23 days [14-85]. Skin reaction delayed surgery for one patient. Most had skin-sparing mastectomy (92%) and axillary lymph node dissection (67%). 12 surgeons performed the reconstructions: 35 deep inferior epigastric perforators; 4 profunda artery perforator; 2 muscle-sparing transverse rectus abdominis myocutaneous; 1 latissimus dorsi (LD); 2 LD/implant; 2 LD/tissue expander (TE); and 2 subpectoral (SP) TE. There were no complete flap losses. Two patients (4.4%, 95% CI 0.5%-14.8%) with free flaps had partial flap loss with revision surgery. Both patients with SP TEs had infections and unplanned reoperation. The protocol was subsequently amended to not allow SP TE reconstruction. Eight patients had skin flap necrosis: 5 partial and 3 full thickness necrosis; only 1 required operative debridement. Seven had pathologic complete response. At six months 19/31 (61%) reported being "quite a bit" or "very much" satisfied with how they looked in the mirror clothed. There are no recurrences with a median follow up of 33 months [5-119]. Radiation treatment of the breast and lymph node basins prior to mastectomy with immediate autologous reconstruction is feasible. There were no autologous flap loses and complication rates are similar to reconstruction after radiation series. This promising strategy reduces time to autologous reconstruction and merits further prospective study.

Outcome analysis of thickness-gradient, leaflet-shaped acellular dermal matrix in abdominal fascial defect repair in muscle-sparing TRAM flap based breast reconstruction.

Numerous fascial closure techniques have been used to reduce donor site morbidities after transverse rectus abdominis myocutaneous (TRAM) flap harvest. A leaflet-shaped acellular dermal matrix (ADM) with a thickness gradient was designed to cover the defect effectively and to withstand the pressure applied to the lower portion of the defect. The complication and functional recovery rates of the donor site of the custom ADM were compared with those of previous methods of fascial closure (primary closure and polypropylene mesh assisted closure). A retrospective review of patients undergoing immediate or delayed breast reconstruction using muscle-sparing TRAM flaps was performed. Abdominal bulging, hernia, wound dehiscence, infection, seroma, and hematoma rates were compared. The Back Performance Scale measured four months postoperatively was compared to evaluate the donor site's recovery rate. A total of 173 patients were analyzed. The three groups did not differ in hernia, wound dehiscence, infection, and hematoma rates. However, the abdominal bulging rate was lower in the primary closure group, while the seroma rate was higher in the mesh group. Functional recovery was the fastest in the custom ADM group. A thickness-gradient, leaflet-shaped ADM can be effectively used as an onlay graft to cover the abdominal fascial defect, with similar complication rates, while providing a faster recovery of abdominal function.

Effect of Post-Mastectomy Autologous versus Implant Reconstruction on Body Image and Quality of Life among Egyptian Women

Abstract Purpose The ultimate goal is to evaluate patient satisfaction with autologous versus implant breast reconstruction, as well as the influence of these surgeries on the quality of life and body image of women who have had a mastectomy for breast cancer. Method A multicenter, retrospective, cross-sectional study included 117 patients who underwent mastectomy and subsequent breast reconstruction surgery at El Demerdash University Hospital and Alexandria Main University Hospital between January 2017 and March 2021. A BREAST-Q 2-0 Reconstruction module questionnaire was given to each patient. Result 117 patients were divided into two groups: autologous breast reconstruction ABR (n = 77) and implant-based breast reconstruction IBR (n = 40). The ABR group was operated on using Transverse Rectus Abdominis Myocutaneous (TRAM) or latissimus Doris (LD) flaps. The average age of the participants in the study was 44.51 ± 6.88. Patients with silicone implants were younger on average than those with LD or TRAM flaps. The patient's quality of life in the two areas evaluated (psychosocial and physical well-being) was excellent in implant repair but poor in TRAM flap, according to our findings. In TRAM flap, we also discovered that overall satisfaction with the breast was low. Conculsion TRAM flap produces a low quality of life and overall satisfaction with the breast, whereas implant reconstruction provides a high quality of life.

Norepinephrine preserved flap blood flow compared to phenylephrine in free transverse rectus abdominis myocutaneous flap breast reconstruction surgery: A randomized pilot study

Vasopressors are used in up to 85% of cases during free flap surgery. However, their use is still debated with concerns of vasoconstriction-related complications, with rates up to 53% in minor cases. We investigated the effects of vasopressors on flap blood flow during free flap breast reconstruction surgery. We hypothesized that norepinephrine may preserve flap perfusion better than phenylephrine during free flap transfer. A randomized pilot study was performed in patients undergoing free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. Patients with peripheral artery disease, allergies to study drugs, previous abdominal operations, left ventricular dysfunction, or uncontrolled arrhythmias were excluded. Twenty patients were randomized to receive either norepinephrine (0.03-0.10µg/kg/min) or phenylephrine (0.42-1.25µg/kg/min) (each n=10) to maintain a mean arterial pressure of 65-80mmHg. The primary outcome was differences in mean blood flow (MBF) and pulsatility index (PI) of flap vessels after anastomosis measured using transit time flowmetry in the two groups. Secondary outcomes included flap loss, necrosis, thrombosis, wound infection, and reoperation within 7 days postoperatively. After anastomosis, MBF showed no significant change in the norepinephrine group (mean difference, -9.4±14.2mL/min; p=0.082), whereas it was reduced in the phenylephrine group (-7.9±8.2mL/min; p=0.021). PI did not change in either group (0.4±1.0 and 1.3±3.1 in the norepinephrine and phenylephrine groups; p=0.285 and 0.252, respectively). There were no differences in secondary outcomes between the groups. During free TRAM flap breast reconstruction, norepinephrine seems to preserve flap perfusion compared to phenylephrine. However, further validation studies are required.

PC43. Satisfaction with Breasts among Patients Undergoing Abdominal Free Flap Breast Reconstruction: Identification of Factors in 919 Patients

PURPOSE: Previous studies suggest that patients who choose autologous breast reconstruction have significantly higher satisfaction with their breasts than those with implant-based reconstruction. Of all donor sites, abdominal-based reconstruction has become the gold standard. This study aimed to present factors associated with Satisfaction with Breasts among patients who underwent abdominal free flap breast reconstruction. METHODS: We performed a retrospective analysis of women with abdominal-based breast reconstruction between 2010 and 2021. Patients who completed the BREAST-Q Satisfaction with Breasts module and underwent either transverse rectus abdominis myocutaneous (TRAM), deep inferior epigastric artery perforator (DIEP), or superficial inferior epigastric artery (SIEA) were included. RESULTS: Overall, 919 women who underwent abdominal-based breast reconstruction completed the BREAST-Q at 1-year follow-up. The median score improved from 46 (interquartile range, 33 to 58) preoperatively to 64.0 (53 to 78) at 1-year postoperatively. Factors significantly associated with decreased postoperative Satisfaction with Breasts score included lower preoperative scores (beta=0.12, p=0.012), Black (beta=-4.7, p=0.031) or Other ethnicity (beta=-13, p<0.001, versus White), and history of psychiatric (beta=-5.4, p<0.001) and cardiovascular disease (beta=-4.0, p=0.010). Patients who had radiation reported significantly decreased score compared to those who did not (beta=-6.5, p<0.05). Variables including BMI, timing of reconstruction (immediate versus delayed), laterality, and complications were not associated with the 1-year postoperative score. CONCLUSION: Factors that influence long-term Satisfaction with Breasts following autologous breast reconstruction include lower preoperative score, Black or Other race, a history of psychiatric or cardiovascular disorders, and radiation. Understanding these factors is imperative in managing expectations and preoperative counseling.

Preoperative planning of unilateral breast reconstruction with pedicled transverse rectus abdominis myocutaneous (TRAM) flaps: a pilot study of perforator mapping.

Pedicled transverse rectus abdominis myocutaneous (TRAM) flaps are well-established autologous reconstructive options for breast reconstruction. Preoperative computed tomographic angiography (CTA) has since become part of the routine workup in breast reconstruction with deep inferior epigastric artery perforator (DIEP) flaps. CTA provides an improved understanding of perforator anatomy which can facilitate optimal choice of hemiabdominal wall, and guide sheath harvest. Despite this knowledge, the role of preoperative CTA for breast reconstruction with the pedicled TRAM flap has not yet been established. A consecutive cohort of patients undergoing breast reconstruction with pedicled TRAM flaps without preoperative imaging were compared to a similar cohort of consecutive patients undergoing the same procedure with the use of preoperative CTA. Both flap and donor outcomes were assessed. Thirty-four consecutive patients undergoing ipsilateral breast reconstruction with pedicled TRAM flaps were included. There was no statistical difference in the operative times or outcomes between the two groups. There were no complete flap losses in either group. The use of preoperative CTA may help to guide surgical technique and provide the surgeon with greater confidence intraoperatively, however, this study did not show significant change in operative outcomes. Further study and risk/benefit analysis may better highlight the role of CTA in pedicled TRAM flap planning.

DESMOID TUMOUR OF ANTERIOR ABDOMINAL WALL: A CASE REPORT

Desmoid tumours are broblastic neoplasms which show aggressive inltrative behaviour and can cause mass effect. They should be monitored for asymptomatic patient as there is a possibility of spontaneous regression. For patients with rapidly growing or symptomatic tumors resection is recommended. If complete pathologic resection is not achievable without signicant morbidity, more modest resection is recommended along with treatment with adjuvant therapies. A 36-year-old female presented to the surgery OPD with the complaint of lump in left iliac fossa for last 2 years, initially 3 x 2 cm in size but gradually increasing in size with stable vitals and examination nding of lump palpable in left iliac fossa of size 20 x 15cm, hard in consistency, not xed to skin, mobile, non-tender and becoming prominent on leg raising test. MRI pelvis was suggestive of 17.1 x 12.8 x 11.4cm, T2 hypointense lesion in left hemipelvis with extension into the hypogastrium and left iliac fossa, inltrating the left anterior abdominal wall in the left iliac fossa and hypogastrium and reaching to skin surface via large defect in the abdominal wall size, abutting and displacing the urinary bladder and left external and internal iliac vessels with the angle of contact less than 90 degrees with the vessels and left ovary not visualised separate from the lesion. FNAC was suggestive of spindle cell tumour. The patient successfully underwent wide local excision along with left oopherectomy, mesh repair and transverse rectus abdominis myocutaneous (tram) ap. Conclusion: Since, desmoid tumors are locally aggressive and invasive, timely surgical intervention with resection in this patient prevented further progression of the tumour and the high probability of invasion and involvement of major blood vessels thus signicantly reducing the fatality.

Reconstruction of chronic radiation-induced ulcers in the chest wall using free and pedicle flaps.

Resection of radiation-induced ulcers often causes full-thickness defects of the chest wall. We retrospectively reviewed and evaluated 17 patients to explore a method of chest wall reconstruction. A total of 17 breast cancer patients with radiation-induced ulcers were included. Various type of prostheses and flaps were used, results of clinic were evaluated. Sixteen patients had full-thickness defects and one patient had only a soft tissue defect and underwent reconstruction with a pedicle latissimus dorsi (LD) myocutaneous flap. Among all 16 full-thickness defect cases, 15 patients underwent bony thoracic reconstruction using polymesh/3D-printed titanium plates or methyl methacrylate. For soft tissue reconstruction, 13 patients reconstruction using a free deep inferior epigastric perforator (DIEP) flap in combination with a contralateral transverse rectus abdominis myocutaneous (TRAM) flap, and 2 underwent pure free DIEP flap reconstruction. Among all the patients 15 healed with no complications, and 2 patients had delayed healing on the edges of the flaps. Distant pedicle or free flap can used for soft tissue defect coverage, for those severe patients with full-thickness defects and used prostheses, free deep inferior epigastric perforator flap in combination with a contralateral transverse rectus abdominis myocutaneous flap (TRAM + DIEP) would be an applicable choice.

62 (PB-062) Poster - A comparative analysis between vertical rectus abdominis myocutaneous (VRAM) flap and transverse rectus abdominis myocutaneous (TRAM) flap as options for post-mastectomy chest wall reconstruction

Background: Oncoplastic breast reconstruction prevents the chest wall deformities occurring after a mastectomy or occurring after chest irradiation following lumpectomy. It offers lower morbidity, higher quality of life and a more natural aesthetic outcome than traditional breast reconstruction techniques. Free flaps offer great cosmetic results and also prevent donor site morbidity but they require advanced microsurgical techniques that may be difficult in institutions with constraints of resources.

Delivery technique for the pedicled transverse rectus abdominis myocutaneous flap

The pedicled transverse rectus abdominis myocutaneous (TRAM) flap is often used during breast reconstruction. After completely elevating the flap, a medial tunnel is created to connect the dissection area to the mastectomy defect. This tunnel should typically accommodate four of the surgeon’s fingers, although this may vary depending on flap volume. Wider tunneling facilitates flap delivery, but can damage the breast and inframammary fold. Therefore, we introduce a technique to move the flap easily and safely through a small tunnel. During breast reconstruction using a pedicled TRAM flap, a tunnel was made in the mastectomy defect along the meridian of the breast. This tunnel accommodated a width of three of the surgeon’s fingers (6 cm). After completely elevating the flap, it was inserted into a funnel with an inner surface made of polymeric vinyl and a hydrophilic coating. The flap was propelled into the mastectomy defect via the funnel. Our novel technique for pedicled TRAM flap delivery using a funnel was easy and safe, and it is deemed to be suitable for delivering a pedicled TRAM flap.

The "Nipple-Licus": the Everted Umbilicus for Immediate Nipple Reconstruction in Mid-Abdominal Transverse Rectus Abdominis Myocutaneous Breast Reconstruction

Comparison of nine methods of immediate breast reconstruction after resection of localized breast cancer: A cost‐effectiveness Markov decision analysis of prospective studies

Women undergoing immediate breast reconstruction without radiation therapy have reconstruction methods available with uncertain long-term costs associated with complications requiring surgery and revisions. We evaluated cost-effectiveness of nine methods of immediate breast reconstruction for women with localized breast cancer. Markov modeling was performed over 10-years for unilateral/bilateral breast reconstructions from healthcare/societal perspectives. PubMed, Embase, Cochrane, Scopus, and CINAHL were searched to derive data from 13,744 patients in 79 prospective studies. Complications requiring surgery (mastectomy necrosis, total/partial flap necrosis, seroma, hematoma, infection, wound dehiscence, abdominal hernia, implant removal/explantation) and revisions (fat necrosis, capsular contracture, asymmetry, scars/redundant tissue, implant rupture/removal, fat grafting) were evaluated over yearly cycles. Reconstructions included: direct-to-implant (DTI), tissue expander-to-implant (TEI), latissimus dorsi flap-to-implant (LDI), latissimus dorsi (LD), pedicled transverse rectus abdominis myocutaneous (TRAM), free TRAM, deep inferior epigastric perforator/superficial inferior epigastric artery (DIEP/SIEA), thigh-based, or gluteal based flaps. Outcomes were incremental cost-effectiveness ratios (ICER) and net monetary benefits (NMB). Willingness-to-pay thresholds were $50,000 and $100,000. From a healthcare perspective for unilateral reconstruction, compared to LD, the ICER for DTI was -$42,109.35/quality-adjusted life-years (QALY), LDI was -$25,300.83/QALY, TEI was -$22,036.02/QALY, DIEP/SIEA was $8307.65/QALY, free TRAM was $8677.26/QALY, pedicled TRAM was $13,021.44/QALY, gluteal-based was $17,698.99/QALY, and thigh-based was $23,447.82/QALY. NMB of DIEP/SIEA was $404,523.47, free TRAM was $403,821.40, gluteal-based was $392,478.64, thigh-based was $387,691.70, pedicled TRAM was $376,901.83, LD was $370,646.93, DTI was $339,668.77, LDI was $334,350.30, and TEI was $329,265.84. All nine methods of immediate breast reconstruction were considered cost-effective from healthcare/societal perspectives. LD provided the lowest costs, while DIEP/SIEA provided the greatest effectiveness and NMB.

Prevention of Abdominal Bulging Using Onlay Dermal Autografts from Discarded Zone IV TRAM Flap Tissue.

While the transverse rectus abdominis myocutaneous (TRAM) flap is a popular option for abdominal-based breast reconstruction, abdominal wall morbidities such as bulging or hernia remain a concern. Here, we introduced a surgical technique for reinforcing the abdominal wall using an onlay autograft obtained from discarded zone IV tissue following a primary closure. We compared abdominal wall morbidities between patients receiving an onlay graft and those receiving primary closure only. We retrospectively reviewed the medical charts of patients who underwent breast reconstruction using a TRAM flap between December 2018 and May 2021. Additionally, we assessed donor-site morbidities based on physical examination. Of the 79 patients included, 38 had received a dermal graft and 41 had not. Donor-site morbidities occurred in 10 (24.5%) and 1 (2.6%) patients, and bulging occurred in 8 (19.5%) and 1 (2.6%) patients in the primary closure and dermal autograft groups, respectively. A statistically significant difference in the incidence of bulging was observed between the groups (p = 0.030). In conclusion, the introduction of a dermal autograft after primary closure can successfully ameliorate morbidities at the TRAM flap site.

Autologous Reconstruction after Mastectomy for Breast Cancer.

Background:Women undergoing autologous reconstruction (AR) after mastectomy for breast cancer and their surgeons must make decisions regarding timing of the AR and choose among various flap types. We conducted a systematic review to evaluate the comparative benefits and harms of (1) timing of AR relative to chemotherapy and radiation therapy, and (2) various flap types for AR.Methods:We searched Medline, Embase, Cochrane CENTRAL, CINAHL, and ClinicalTrials.gov for studies, from inception to March 23, 2021, without language restriction. We assessed risk of bias of individual studies and strength of evidence (SoE) of our findings using standard methods.Results:We screened 15,936 citations. Twelve mostly high risk of bias studies, including three randomized controlled trials and nine nonrandomized comparative studies met criteria (total N = 31,833 patients). No studies addressed timing of AR relative to chemotherapy or radiation therapy. Six flap types were compared, but conclusions were feasible for only the comparison between transverse rectus abdominus myocutaneous (TRAM) and deep inferior epigastric perforator (DIEP) flaps. The choice of either flap may result in comparable patient satisfaction with breasts and comparable risk of necrosis (low SoE for both outcomes), but TRAM flaps probably pose a greater risk of harm to the area of flap harvest (abdominal bulge/hernia and need for surgical repair) (moderate SoE).Conclusions:Evidence regarding details for AR is mostly of low SoE. New high-quality research among diverse populations of women is needed for the issue of timing of AR and for comparisons among flap types.

Incidence and Outcomes of Completion Mastectomy following Oncoplastic Reduction: A Case Series.

Background:Patients occasionally need completion mastectomy (CM) following oncoplastic reduction for various reasons necessitating definitive reconstructive techniques. The purpose of this study was to evaluate those patients who required CM following oncoplastic reduction and evaluate indications, technique, and outcomes.Methods:Patients who underwent a completion mastectomy at some time point following the oncoplastic reduction were identified. Factors that influenced CM and additional reconstruction were analyzed. All statistical analysis was conducted using the IBM SPSS Statistics 27.0 (IBM Corp.).Results:A total of 29 patients (5.3%) underwent CM during the study period with an average follow-up of 3 years since the original procedure. The most common reasons were positive margins (20/29, 69.0%) and recurrence (8/29, 27.6%). Twenty-two had reconstructive procedures (75.9%) and seven did not (24.1%). The patients who underwent CM and reconstruction were significantly younger (49.2 years) than those who had no reconstruction (64.3 years, P = 0.004). The most common type of reconstruction was transverse rectus abdominis myocutaneous (TRAM)/deep inferior epigastric perforator (DIEP) flap (12/22, 54.5%), followed by latissimus (6/22, 27.3%) and tissue expander (3/22, 13.6%). The complication rate in the CM group was 24% (N = 7/29), which included two seromas (6.9%), followed by infection, fat necrosis, mastectomy skin necrosis, and donor site necrosis (3.4% each).Conclusions:Completion mastectomy is indicated typically for positive margins or recurrence. Reconstruction is performed more frequently in younger patients, with the TRAM/DIEP flap and latissimus dorsi reconstruction being the most common technique.

Comparative analysis of skin color in breast reconstruction using pedicled transverse rectus abdominis myocutaneous flaps

Background A recent concern in breast reconstruction procedures is skin color mismatch of the pedicled transverse rectus abdominis myocutaneous (TRAM) flap. With the goal of objectively quantifying the skin tone of the TRAM flap donor site, contralateral breast, and flap, a comparative study was conducted.Methods This study was conducted in July 2021, included 17 patients who received delayed breast reconstruction via TRAM flaps from January 2016 to December 2020 with at least 12 months of follow-up. Melanin levels and redness values of the flap, abdomen, and contralateral breast were measured in patients using a skin pigmentation analyzer. Furthermore, in 20 healthy women in their 40s to 60s, measurements were made of the abdomen, as well as breast.Results The contralateral breast had lower mean melanin and redness than the abdomen. The flaps had slightly higher melanin levels than the contralateral breasts. The flaps tended to have higher redness values, but the difference was not significant. The difference between the flap and abdomen was significant for melanin, but not redness. Preoperative radiotherapy did not affect skin tone. The upper abdomen showed lower melanin and redness than the lower abdomen.Conclusions The breast had a brighter skin tone than the abdomen. The upper abdomen showed brighter skin tone than the lower abdomen, and the area used as the donor site of the TRAM flap presented the same tendency. In the process of TRAM flap engrafting, the melanin level of the tissue decreases, and the redness value tends to increase slightly compared to the contralateral breast.
