BACKGROUND: Individual outcomes may not accurately reflect the quality of perioperative care. Textbook outcomes (TOs) are composite metrics that provide a comprehensive evaluation of hospital performance and surgical quality. This study aimed to investigate the prevalence and predictors of TOs in a multi-institutional cohort of patients who underwent breast reconstruction with deep inferior epigastric artery perforator flaps.
METHODS: For autologous reconstruction, a TO was previously defined as a procedure without intraoperative complications, reoperation, infection requiring intravenous antibiotics, readmission, mortality, systemic complications, operative duration ≤12 hours for bilateral and ≤10 hours for unilateral/stacked reconstruction, and length of stay (LOS) ≤5 days. We investigated associations between patient-level factors and achieving a TO using multivariable regression analysis.
RESULTS: Of 1000 patients, most (73.2%) met a TO. The most common reasons for deviation from a TO were reoperation (9.6%), prolonged operative time (9.5%), and prolonged LOS (9.2%). On univariate analysis, tobacco use, obesity, widowed/divorced marital status, and contralateral prophylactic mastectomy or bilateral reconstruction were associated with a lower likelihood of TOs (P < 0.05). After adjustment, bilateral prophylactic mastectomy (odds ratio [OR], 5.71; P = 0.029) and hormonal therapy (OR, 1.53; P = 0.050) were associated with a higher likelihood of TOs; higher body mass index (OR, 0.91; P = <0.001) was associated with a lower likelihood.
CONCLUSIONS: Approximately 30% of patients did not achieve a TO, and the likelihood of achieving a TO was influenced by patient and procedural factors. Future studies should investigate how this metric may be used to evaluate patient and hospital-level performance to improve the quality of care in reconstructive surgery.

BACKGROUND: Tissue expander-based breast reconstruction is associated with high rates of infectious complications, often leading to tissue expander explants and delays in receipt of definitive breast reconstruction and adjuvant therapy. In this study, we describe a single-stage technique where deep inferior epigastric artery perforator (DIEP) flaps are used to salvage actively infected tissue expanders among patients originally planning for free flap reconstruction.
METHODS: In this technique, patients with tissue expander infections without systemic illness are maintained on oral antibiotics until the day of their DIEP flap surgery, at which time tissue expander explant is performed in conjunction with aggressive attempt at total capsulectomy and immediate DIEP flap reconstruction. Patients are maintained on 1-2 weeks of oral antibiotics tailored to culture data. Patients undergoing this immediate salvage protocol were retrospectively reviewed, and complications and length of stay were assessed.
RESULTS: In a retrospective series, a total of six consecutive patients with culture-proven tissue expander infections underwent tissue expander removal and DIEP flap reconstruction in a single stage and were maintained on 7-14 days of oral antibiotics postoperatively. Within this cohort, no surgical site infections, microvascular complications, partial flap losses, reoperations, or returns to the operating room were noted within a 90-day period.
CONCLUSIONS: Among a select cohort of patients, actively infected tissue expanders may be salvaged with free flap breast reconstruction in a single surgery with a low incidence of postoperative complications. Prospective studies are needed to evaluate the influence of this treatment strategy on costs, number of surgeries, and dissatisfaction after staged breast reconstruction complicated by tissue expander infections.

BACKGROUND: Breast reconstruction with the deep inferior epigastric perforator (DIEP) flap is the current gold-standard autologous option. The profunda artery perforator (PAP) and lumbar artery perforator (LAP) flaps have more recently been described as alternatives for patients who are not candidates for a DIEP flap. The aim of this study was to review the survival and complication rates of PAP and LAP flaps, using the DIEP flap as a benchmark.
METHODS: A literature search was conducted using PubMed, MEDLINE, Embase, BIOSIS, Web of Science, and Cochrane databases. Papers were screened by title and abstract, and full texts reviewed by three independent blinded reviewers. Quality was assessed using MINORS criteria.
RESULTS: Sixty-three studies were included, for a total of 745 PAP, 62 stacked PAP, 187 LAP, and 23,748 DIEP flap breast reconstructions. The PAP (98.3%) had comparable success rate to DIEP (98.4%), and the stacked PAP (88.7%) and LAP (92.5%) success rate was significantly lower (P < 0.0001). The PAP and LAP groups both had a low incidence of fat necrosis. However, the revision rate for the LAP group was 16.1% whereas the PAP group was 3.3%. Donor site wound dehiscence rate was 2.9 in the LAP group and 9.1% in the PAP group.
CONCLUSIONS: Profunda artery perforator and DIEP flaps demonstrate very high rates of overall survival. The LAP flap has a lower survival rate. This review highlights the survival and complication rates of these alternative flaps, which may help clinicians in guiding autologous reconstruction technique when a DIEP flap is unavailable.

BACKGROUND: Dynamic infrared thermography (DIRT) is a quick and non-invasive technique for perforator mapping in free flaps that provides real-time information. After a cold challenge, areas best supplied with blood become visible hotspots on color-coded maps, indicating perforators. This study presents a proof of principle for a new and innovative feature of DIRT, where projected augmented reality is used to directly display thermal images on the patient\'s abdomen prior to the deep inferior epigastric artery perforator (DIEP) flap breast reconstruction.
METHODS: A self-aligning projection device prototype (Anatomy Projector) equipped with an integrated thermal camera was used to obtain thermal information and project the color-coded map directly on the patient\'s abdomen before DIEP flap breast reconstruction. Projected DIRT hotspots were verified using a hand-held Doppler, and compared to the vascularity on computed tomography angiography (CTA), and intraoperative perforator measurements following a Cartesian grid.
RESULTS: A total of 514 DIRT hotspots were projected in 50 patients, among them 97.3% could be verified using Doppler. The positive predictive value for CTA was 74.5%. Intraoperative measurements yielded 132 perforators in 71 flaps, among them 75 perforators (56.8%) correlated with projected DIRT hotspots, and half of them (54.7%) appeared within the first 5 emerging hotspots.
CONCLUSIONS: This study showed that real-time display of thermal data in DIEP flap breast reconstruction is feasible via projected augmented reality. Projection facilitates convenient marking of hotspots, and a high resemblance to Doppler and CTA data was observed. Further research should assess the added value of projecting thermal images intraoperatively and in other fields of plastic surgery.

Superficial inferior epigastric artery (SIEA) flap is often chosen to minimize postoperative complications such as abdominal pain and bulging. However, drawbacks, including a small diameter and a short pedicle, pose challenges in anastomosing or creating the lower pole of the breast. Here, we report a case of breast reconstruction using an SIEA flap with pedicle elongation via an arteriovenous loop (AV-loop) using a contralateral superficial inferior epigastric vein (SIEV) graft. A 49-year-old woman underwent a left total mastectomy with the primary insertion of a tissue expander. Breast reconstruction using an SIEA flap with pedicle elongation was planned. The running pattern, pedicle length, and diameter of bilateral SIEA/SIEV and superficial circumflex iliac artery and vein (SCIA/SCIV) were evaluated preoperatively using a 48-MHz probe of ultra-high-frequency ultrasonography (Vevo MD ultrasound device, Fujifilm Visual Sonics, Amsterdam, the Netherlands). During the flap harvesting, the contralateral SIEV graft was harvested to create an AV-loop for pedicle elongation. The 9 cm graft was anastomosed to the left internal mammary artery and vein (IMA/IMV). After the flap elevation, the created AV-loop was divided at the midpoint and anastomosed to the pedicle of the SIEA flap. The SIEA flap, extended with a SIEV AV-loop, facilitated the augmentation of the lower pole of the breast without the risk of pedicle kinking and pulling. The postoperative course was uneventful, and the patient was discharged on postoperative day 7. The prolonged pedicle length via an AV-loop prevents the pedicle kinking and allows for positioning the flap more freely, resulting in an aesthetically good breast contour by filling in the lower pole. The precise preoperative evaluation of the vessels using ultra-high-frequency ultrasonography facilitated meticulous planning. In cases where surgeons aim to minimize intraoperative and postoperative complications associated with other abdominal free flaps, this method may be considered a viable and promising option.

BACKGROUND: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.

BACKGROUND: The deep inferior epigastric perforator (DIEP) flap is widely considered as the gold standard in breast reconstruction. The inset technique of the DIEP flap is crucial in determining the overall aesthetic outcome; however, to date no systematic review is available that comprehensively assesses the various techniques. Evaluation of topic: A systematic review was performed according to the PRISMA guidelines. The methodology is outlined within our published protocol (Prospero CRD42023449477). Included articles met a minimal criterion compromising of the intervention (DIEP free flap for breast reconstruction) and outcomes (aesthetic and clinical outcomes). Six articles were included in this review, with a total of 346 patients and a follow-up ranging from 6 months to 4 years. Four articles were of a prospective case series study design, one article was a randomized controlled trial, and one article was a case-control study. The risk of bias was assessed to be high in the case series, but low and moderate in the randomized controlled trial and case-control study respectively.
CONCLUSIONS: Although limited by the quality of the evidence, the single aesthetic unit principle, dual-plane inset, elimination of the need for a skin paddle, appropriate flap positioning and rotation, and algorithmic in-setting may all improve the aesthetic outcome of DIEP free flaps.

Here we describe a template of DIEP flap inset that prioritises projection, lateral flow and natural ptosis; key elements of an aesthetically successful delayed breast reconstruction. By not excising the full length of the mastectomy scar, and preserving the scar laterally, we increase the 3-dimensional aesthetic of the breast, moving the final reconstructed breast aesthetic further away from an unintentional 2-dimensional resurfacing. Through controlling the initial take-off around the whole circumference of the breast footprint, a favourable and durable breast conus is consistently achieved. This technique employs designated segments of comparatively more rigid irradiated mastectomy skin flaps, to positively influence reconstructed breast aesthetics at the time of flap inset. Conceptually, this reminds the authors of how the green sepals of a rose shape the bud of petals.

BACKGROUND: Implants and DIEP flaps have different outcomes regarding postoperative breast sensation. When compared to the preoperative healthy breast, implant-based breast reconstruction (IBBR) negatively influences postoperative breast sensation. However, it is currently unknown whether a prior IBBR also influences postoperative sensation of a replacing DIEP flap. The goal of this cohort study is to evaluate the influence of an IBBR on the postoperative sensation of a replacing DIEP flap.
METHODS: Women were included if they received a DIEP flap reconstruction after mastectomy, with or without prior tissue expander (TE) and/or definitive breast implant. Sensation was measured at four intervals in 9 areas of the breast with Semmes-Weinstein monofilaments: T0 (preoperative, implant/no reconstruction), T1 (2-7 months postoperative, DIEP), T2 (± 12 months postoperative, DIEP), Tmax (maximum follow-up, DIEP). Linear mixed-effects models were used to investigate the relationship between an implant/TE prior to the DIEP flap and recovery of breast sensation.
RESULTS: 142 women comprising 206 breasts were included. 48 (23.3%) breasts did, and 158 (76.7%) breasts did not have a TE/IBBR prior to their DIEP. No statistically significant or clinically relevant relationships were found between a prior implant/TE and recovery of DIEP flap breast sensation for the flap skin, native skin, or total breast skin at T1, T2, or Tmax. There were also no relationships found after adjustment for the confounders radiation therapy, BMI, diabetes, age, flap weight, follow-up, and nerve coaptation.
CONCLUSIONS: An implant/TE prior to a DIEP flap does not influence the recovery of postoperative breast sensation of the DIEP flap.
