Optimal Use of Drain Tubes for DIEP Flap Breast Reconstruction: Comprehensive Review

Background: Deep inferior epigastric perforator (DIEP) flap breast reconstruction is an increasingly popular technique, but controversy exists regarding the optimal use of closed suction drains (CSD) at the abdominal donor site. This narrative review synthesizes current evidence on CSD application, criteria for placement/removal, and complications in DIEP flap procedures. Alternative techniques and implications for postoperative care are also discussed. Methods: A systematic search was conducted in August 2024 across several databases to identify English language studies related to CSD use in DIEP flap breast reconstruction. Inclusion criteria consisted of original research on aspects such as CSD volume criteria, timing, complications, alternatives like progressive tension sutures, and impact on showering and patient outcomes. References from relevant papers were hand-searched. Results: The review found a lack of consensus on CSD protocols, with drainage volume triggering removal varying widely from 5 mL to 80 mL daily. While CSD may reduce seroma/hematoma formation, earlier removal (≤3 days) did not increase complications and shortened hospital stay. Progressive tension sutures show promise as an alternative, with evidence of comparable or reduced complications and improved recovery versus CSD. The safety of early showering with drains remains unclear. Conclusions: Although CSD aims to minimize postoperative complications, more rigorous randomized trials are needed to establish evidence-based practices for the timing of removal and demonstrate the efficacy of emerging drain-free techniques on patient-centered outcomes. Standardized criteria could reduce practice variability. Further research should also explore the long-term impact of drainage strategies on aesthetic and functional results.

Linked Flaps of the Thoracodorsal Vascular Tree for Correcting Extensive Post-Burn Deformities and Achieving Optimal Reconstruction Outcomes.

Autologous skin grafting has been the popular method for reconstructing post-burn defects. However, this technique has limitations such as high contracture rates and inadequate volume coverage. This report aims to propose the principles and advantages of utilizing microsurgically linked perforator flaps for the reconstruction of extensive burn defects and associated post-burn scar contracture in the lower and upper extremities and trunk. Patients who underwent free tissue transfer for primary and secondary burn wound reconstruction at a single institution between 2016 and 2023 were included in the study. Patients received thoracodorsal vascular tree-linked flaps for the correction of post-burn deformities. Postoperative results were evaluated, including flap survival, complications, and the DASH self-report questionnaire for upper extremity reconstruction. Among the 20 patients, 12 required primary reconstruction, while 8 underwent secondary reconstruction using anastomotic chimeric free tissue transfer. The majority of burn injuries resulted from thermal contact (n = 8), followed by flames (n = 5), scalds (n = 4), electrical contact (n = 2), and friction (n = 1). The most frequently utilized combinations were the thoracodorsal artery perforator (TDAp) and anterolateral thigh (ALT) flap (11 cases). Additionally, four cases involved the pedicled TDAp flap in conjunction with the deep inferior epigastric artery perforator (DIEP) flap. The average DASH score for upper extremity burn patients was 10.58. Three-dimensional tissue coverage achieved through the linkage of two or even three independent free flaps is increasingly utilized in post-burn reconstruction. This approach offers multiple advantages and represents a viable option for burn reconstruction.

Comparison of Breast Sensibility Following Breast Reconstruction with Two Different Techniques: Deep Inferior Epigastric Perforator Flap and Implant

Introduction: Breast sensibility following reconstruction surgery, though often overlooked, holds significant importance due to its widespread occurrence and profound effects on patients’ well-being and safety. The author’s objective is to compare the sensory outcomes between deep inferior epigastric perforator (DIEP) flap microsurgery reconstruction and implant-based reconstruction. Additionally, the potential influence of sociodemographic and clinical factors on sensory recovery is explored, along with assessing temperature discrimination abilities and evaluating quality of life. Material and methods: An ambispective descriptive-analytical study was conducted involving women who underwent mastectomy with reconstruction using either DIEP flap and implants at the author’s hospital between 1990–2021. Data were collected from medical records, patient histories, physical examinations, and validated quality of life questionnaires (BREAST-Q). Spearman’s or Pearson’s correlation coefficients were employed for the analysis of quantitative variables, while the Student’s T test or Mann-Whitney U test were used to compare quantitative and qualitative variables. Results: A total of 99 women with breast reconstruction were included, 47 with DIEP flap and 52 with implants. Sensory recovery in implant-based reconstruction was found to be superior to DIEP flap reconstruction (5.03 and 5.18, respectively; p<0.005). A direct correlation was observed between sensory improvement and thermal discrimination (Spearman coefficient 0.9; p<0.001). Factors such as radiotherapy, delayed reconstruction with DIEP flap, and height with implants were associated with poorer sensory recovery in the breast. Women experiencing better breast sensibility reported higher satisfaction with their surgeon, medical team, and psychosocial quality of life. Conclusion: Women reconstructed with implants or DIEP abdominal flap exhibit suboptimal overall sensory recovery of the reconstructed breast, with slightly better outcomes observed in women reconstructed with implants. The development of novel surgical techniques aimed at enhancing sensibility after breast reconstruction could significantly benefit these patients.

Clinical Outcomes Following Profunda Artery Perforator Flap Breast Reconstruction: A Systematic Review and Meta-Analysis.

There is a lack of reliable evidence on the surgical outcomes of profunda artery perforator (PAP) flap breast reconstruction. We conducted a meta-analysis to evaluate its safety and compare it with deep inferior epigastric perforator (DIEP) flap, aiming to offer more information on whether the PAP flap was an ideal alternative for autologous breast reconstruction. PubMed, EMBASE, Web of Science and Cochrane Library were searched to retrieve relevant articles. The postoperative complication rates following PAP reconstruction were pooled. Mean differences of patients' age, BMI, mastectomy weight and flap weight between PAP and DIEP group were calculated, and relative risk was estimated to compare their incidence of complications. Twenty-four articles reporting 1612 PAP flap breast reconstructions were included. The surgical success rate was 99.6%; the incidence of total and partial flap loss was 0.4% and 0.0%; the incidence of infection, hematoma, seroma, fat necrosis and wound dehiscence in recipient sites was 0.3%, 1.4%, 1.0%, 3.3% and 0.3%, respectively; the incidence of infection, hematoma, seroma, wound dehiscence and sensory disturbance in donor sites was 2.0%, 0.9%, 3.5%, 9.2% and 0.6%, respectively. Compared to the DIEP group, the average age, BMI, mastectomy weight and final flap weight were significantly lower in the PAP group. No significant difference was observed in terms of flap failure, breast fat necrosis and donor site wound dehiscence. This systematic review demonstrates similar levels of postoperative morbidities for the PAP and DIEP flaps with some subtle differences and verifies the PAP flap as a second-line treatment for patients when the DIEP is unavailable or undesirable. This journal requires that authors assign a level of evidence to each article.

Evolution and Adaptations of Robotic DIEP Flap Surgery: A Systematic Review.

The integration of robotic technology into surgical procedures has gained considerable attention for its promise to enhance a variety of clinical outcomes. Robotic deep inferior epigastric perforator (DIEP) flap harvest has emerged as a novel approach for autologous breast reconstruction. This systematic review aims to provide a comprehensive overview of the current techniques, outcomes, and complications of robotic DIEP flap surgery. A systematic literature search was conducted after PRISMA 2020 guidelines across databases including PubMed, Embase, Google Scholar, and Web of Science from 2000 to 2023. Articles exploring robotic DIEP flap harvest for breast reconstruction were assessed to compare operative techniques, clinical outcomes, and complications. The risk of bias was evaluated using ROBINS-I and the Newcastle-Ottawa scale. Fourteen studies involving 108 patients were included. Three studies used a totally extraperitoneal (TEP) technique, whereas 11 studies used a transabdominal preperitoneal (TAPP) approach. Preoperative planning utilized computed tomography angiography and magnetic resonance angiography imaging. The mean robotic operative time was 64 minutes, with total operative times averaging 574 minutes for TAPP and 497 minutes for TEP. The mean length of stay was 5 days, and the mean fascial incision length was 3cm. Overall complication rate was 14.9%, with no significant difference compared with conventional DIEP flap procedures. Robotic DIEP flap harvest is a promising technique that may reduce postoperative pain and limiting abdominal donor site morbidity. Potential limitations include longer operative times, variable hospital stays, and increased costs.

Breast reconstruction using the superficial circumflex iliac artery superficial branch perforator (SCISP) flap.

The deep inferior epigastric perforator (DIEP) flap is the gold standard for autologous breast reconstruction. One downside is its risk of postsurgical herniation and bulging due to the opening of the rectus fascia and intramuscular dissection of the rectus abdominis muscle. Additionally this part of the surgery is very time consuming. While the superficial inferior epigastric artery perforator (SIEA) flap has been thoroughly described for total autologous breast reconstruction, the use of the superficial circumflex iliac artery perforator flap in this field is limited. This series introduces the use of an extended superficial circumflex iliac artery (SCIA) perforator flap nourished solely by perforators of the superficial branch of the SCIA- artery for total autologous breast reconstruction.Superficial preparation over the abdominal wall was performed without incising the rectus fascia, dissecting the superficial branch of the SCIA and its accompanying veins and the superficial inferior epigastric vein for additional venous drainage.Four patients underwent successful autologous breast reconstruction with this extended SCIP (superficial circumflex iliac artery perforator)-flap-variation. The term superficial circumflex iliac artery superficial branch perforator (SCISP) flap was introduced to standardize the surgical technique for using only perforators of the superficial branch of the SCIA as free flaps.The SCISP flap is safe and viable for total autologous breast reconstruction, particularly for women with small to medium sized breasts and with superficial dominance of the abdominal vascular system.

Embracing Robotics in Microsurgery: Robotic-Assisted Deep Inferior Epigastric Perforator Flap Breast Reconstruction.

The integration of robotic-assisted surgery (RAS) has transformed various surgical disciplines, including more recently plastic surgery. While RAS has gained acceptance in multiple specialties, its integration in plastic surgery has been gradual, challenging traditional open methods. Robotic-assisted deep inferior epigastric perforator (DIEP) flap breast reconstruction is a technique aimed at overcoming drawbacks associated with the traditional open DIEP flap approach. These limitations include a relatively large fascial incision length, potentially increasing rates of postoperative pain, abdominal bulge, hernia rates, and core weakening. The robotic-assisted DIEP flap technique emerges as an innovative and advantageous approach in fascial-sparing abdominal autologous breast reconstruction. While acknowledging certain challenges such as increased operative time, ongoing refinements are expected to further improve the overall surgical experience, optimize results, and solidify the role of robotics in advancing reconstructive microsurgical procedures in plastic surgery. Herein, the authors provide an overview of robotic surgery in the context of plastic surgery and its role in the DIEP flap harvest for breast reconstruction.

A Meta-analysis Comparing Deep Inferior Epigastric Perforator Flaps and Latissimus Dorsi Flaps in Breast Reconstruction.

Deep inferior epigastric perforator (DIEP) flaps and latissimus dorsi (LD) flaps are two widely used breast reconstruction techniques, each with distinct advantages and limitations. This meta-analysis aims to compare patient satisfaction and incidence of complications between these two techniques to inform clinical decision-making. PubMed, Scopus, and Web of Science were searched for relevant studies. We included studies with data comparing DIEP and LD flaps, BREAST-Q patient satisfaction, and complications. Statistical analyses were performed using RevMan 5.4. The search yielded 788 studies, of which 13 were included in the meta-analysis. A total of 2128 patients were analyzed, with 1378 undergoing DIEP flap reconstruction and 750 receiving LD flap reconstruction. The analysis showed greater improvement with DIEP flaps in breast satisfaction [mean difference (MD) = 9.48, 95% confidence interval (CI) = 6.90-12.05, P < 0.00001], physical well-being (MD = 5.95, 95% CI = 2.98-8.92, P < 0.0001), and satisfaction with outcome (MD = 9.36, 95% CI = 3.01-15.71, P = 0.004). Nonetheless, DIEP flaps had higher rates of skin flap necrosis [risk ratio (RR) = 4.27, 95% CI = 2.44 to 7.46, P < 0.00001], wound dehiscence (RR = 5.12, 95% CI = 2.53-10.35, P < 0.00001), and reoperation (RR = 2.24, 95% CI = 1.58 -3.16, P < 0.00001) but lower seroma rates (RR = 0.27, 95% CI = 0.10-0.74, P = 0.01). DIEP flap reconstruction offers superior patient satisfaction compared with LD flap reconstruction, despite a higher incidence of certain complications.

Quality of Video Content Related to Deep Inferior Epigastric Perforator Flap Breast Reconstruction: Social Media Platforms Versus Large Language Models.

The deep inferior epigastric perforator (DIEP) flap is currently one of the main options in breast reconstruction. The information about this surgery is critical for the patient, in order to choose the breast reconstruction method. Our study aims to analyze and compare the quality and accuracy of the information related to the DIEP flap reconstruction method provided by social media platforms (SMPs) and the new large language models (LLMs). A total of 50 videos in English and Spanish were selected from the main SMPs (YouTube, Instagram, and Facebook) using the keywords "DIEP flap" and "colgajo DIEP." The duration, number of likes, dislikes, number of visits, upload date, author, and the video category (institutional video, media, patient experience, academic, and surgery) were analyzed. 3 specific questions were asked to 2 new LLMs (ChatGPT and Google Bard). The quality of information in SMPs and LLMs was analyzed and compared by 2 independent board-certified plastic surgeons using the Journal of American Medical Association and DISCERN scales. LLMs showed a statistically significant higher quality of information when compared with SMPs based on the DISCERN scores. The average DISCERN scores for answers given by ChatGPT and Google Bard were 54 ± 6.841 and 61.17 ± 6.306, respectively (good quality). In SMPs, the average scores were 2.31 ± 0.67 (insufficient quality) and 32.87 ± 9.62 (low quality) for the Journal of American Medical Association and DISCERN scales respectively. Thirty-eight percent of the videos in SMPs were performed by nonmedical authors. The quality of information for breast reconstruction using DIEP flaps from LLMs was considered good and significantly better than in SMPs. The information found in SMPs was insufficient and of low quality. Academic plastic surgeons have an opportunity to provide quality content on this type of reconstruction in LLM and SMPs.

Learning Curve Analysis for Robotic-assisted Harvest of Deep Inferior Epigastric Perforator Flap

Summary: The deep inferior epigastric perforator (DIEP) flap is the preferred method for autologous breast reconstruction after mastectomy, but risks the development of hernia, bulge, and decreased core strength. Robotic harvest of DIEP vessels may limit abdominal wall morbidity through smaller fascial incisions and preservation of motor nerves. This study shows the expected learning curve (LC) for robotic harvest and compares the LC between a general surgeon (GS) and a plastic surgeon (PS). A retrospective cohort study was performed for patients who underwent bilateral robotic DIEP flap harvest from October 2021 to September 2022. We evaluated robotic pedicle dissection time (DT) and compared the times between GS and PS. We calculated LC for each surgeon using the cumulative sum (CUSUM) method, . The LC was identified as the peak of the CUSUM graph. Forty-four flap dissections were recorded during the collection period: 27 by the PS and 17 by the GS. There was no significant difference in DT between the GS and the PS (P = 0.366), and both surgeons saw a decrease in DT over time. Using the CUSUM method, we see the peak of the plot at patient 9 for the PS and the peak of the plot at patient 5 for the GS, after which cumulative DT decreased. As robotic harvest of DIEP flaps becomes accepted, plastic surgeons who wish to incorporate it into their practice may achieve proficiency in their DT within 10 flap harvests and a similar DT compared with robotic-trained GSs.

A Unique Advantage of a 24-hour Surgical Delay in Autologous Breast Reconstruction.

The surgical delay technique can be used effectively in autologous breast reconstruction when there is unfavorable flap vascular anatomy or when the reconstruction necessitates a larger volume of donor tissue to obtain optimal results. The length of time between surgically delaying the flap to pedicle division and inset of the flap often varies based on surgeon preference but is typically approximately a week or longer. The authors present a case in which a 24-hour surgical delay was successfully used to augment deep inferior epigastric perforator flaps for autologous reconstruction. This technique is beneficial as it does not allow time for scarring and adhesions to develop between stages and allows for both stages to be performed in the same hospital admission.

Global perspectives on practices and preferences in Autologous Free Flap Breast Reconstruction: From flap selection to post-operative care: A descriptive quantitative study

BackgroundThe purpose of this study was to evaluate present-day practices in the preparation, peri- and post-operative care for autologous free-flap breast reconstructions (ABR) worldwide, with the aim of enhancing informed decision-making for plastic surgeons during the planning stages of ABR. MethodsA global survey was conducted among 280 plastic surgeons and 39 plastic and reconstructive surgery societies worldwide, inquiring about the flap and donor site selection, surgical actions, perforator imaging and peri-operative care during ABR. ResultsEighty-two responses were received, of which 71% (n=58) were completed questionnaires. The preferred flap choice was the Deep Inferior Epigastric Perforator (DIEP) flap (85%, n=51), with the internal mammary artery as the most commonly used recipient vessel. Pre-operative imaging for ABR was typically performed using Computed Tomography Angiography (75%, n=44) and often combined with a handheld doppler. Handheld doppler was the most frequently used modality to localize perforator vessels during surgery (33%, n=19), with the majority using either one (47%, n=24) or two (51%, n=26) perforators intraoperatively. These preferences were consistent across all clinic types.Post-operatively, flap monitoring was primarily performed by the nursing staff, initially every hour on the first day and then at reduced frequencies on subsequent days.The most commonly used modality for monitoring flap viability was the handheld doppler. The average length of hospital stay was five days. ConclusionThis study provides valuable insights into current preparations, peri- and post-operative care in ABR procedures worldwide, aiding in the development of standardized practices and potentially improving patient outcomes.

Hug Flap and Hamdi Hammock: Two Innovative Techniques for Enhancing Aesthetic Outcomes in Deep Inferior Epigastric Artery Perforator Breast Reconstruction.

Achieving optimal aesthetic outcomes in deep inferior epigastric artery perforator (DIEP) flap breast reconstruction remains a challenge, often necessitating additional procedures for refinement. This study presents two innovative techniques (the hug flap and Hamdi hammock) aimed at enhancing breast projection and inframammary fold (IMF) definition in DIEP flap reconstruction. The hug flap technique uses de-epithelialized caudal mastectomy skin to augment breast projection, whereas the Hamdi hammock uses a percutaneous purse-string suture to define the IMF. A retrospective review of 782 patients who underwent DIEP flap breast reconstruction between 2007 and 2023 was conducted. The hug flap group required significantly less additional fat grafting compared to other techniques (11% versus 27% and 22%). No total flap losses occurred in the hug flap group, and fat necrosis rates were low. The Hamdi hammock was used in 405 patients with a mean of two lipofilling sessions. Complications were minor and no stitches required removal. The hug flap and Hamdi hammock techniques offer effective and safe methods for enhancing breast projection and IMF definition in DIEP flap reconstruction. These techniques may reduce the need for additional procedures and improve aesthetic outcomes.

Gender-affirming DIEP Flap Breast Augmentation.

Implant-based techniques have been the mainstay of gender-affirming breast augmentation (GABA). Here we describe a novel autologous technique for GABA. We provide a single-patient case report of gender-affirming deep inferior epigastric artery perforator (DIEP) flap breast augmentation. World Professional Association for Transgender Health guidelines were followed according to Standards of Care, version 8. Prepectoral tissue expanders were placed at the time of the patient's facial feminization surgery. DIEP flaps were then used for bilateral breast augmentation. Planned revisions were made about 5 months later. Breast augmentation was performed successfully with DIEP flaps, and the patient was satisfied with her outcome. No complications occurred. Anatomic differences to cisgender women were noted, including relatively thick musculature of the abdominal wall and chest as well as tight anterior abdominal fascial closure. Advantages compared with implant-based GABA were also noted, including feminization of the abdomen and avoidance of potential implant related complications. We report a novel approach to GABA. Our approach borrows well-established techniques with demonstrated efficacy and high satisfaction in postmastectomy breast reconstruction and even cosmetic purposes. However, sex- and hormone-influenced anatomic differences required some modifications compared with postmastectomy DIEP flap reconstruction.

Validating the porcine model for microsurgical perforator training: Can surgeons trained on pig perforator dissection successfully perform human DIEP flap procedures? A pilot study

Autologous breast reconstruction, especially using the deep inferior epigastric artery perforator (DIEP) flap, is increasingly seen as a reliable, safe, and long-term alternative to implant-based reconstruction. Despite the recognized advantages of the DIEP flap for breast reconstruction, successful realization demands excellent anatomical knowledge, a thorough understanding of autologous breast reconstruction concepts and advanced microsurgical skills. Given that the porcine model is widely employed in microsurgical training, our study aims to assess this model using validated outcomes, with the objective of evaluating the enhancement in a surgeon's learning curve following training with this model. Forty DIEP flaps were harvested on 20 swines by a single surgeon in "Pius Branzeu Center" (Timisoara, RO) and "Drazan Institute" (University of veterinary of Brno, CZ) laboratories for microsurgical training in 6months (January 2015-June 2015). Then we analyzed data from 40 DIEP flaps harvested by the same surgeon on first 20 consecutive patients undergoing DIEP flap breast reconstruction. Perforator dissection time, surgeon-determined dissection difficulty score (DDS) and venous congestion rate were collected for each flap in porcine model and in patients, then compared and analyzed. The mean of DDS score analysis in first and second swines group dissection resulted as statistically significant (P-value 0.0001), while it was not statistically significant between those analyzed in the second group of swines dissected and patients (P-value 0.8037). Reduction in perforator dissection time between the two swines' groups and in venous congestion rates from the first swines groups to the second to the human group resulted statistically significant too (P-value respectively 0.0001 and 0.0079). The porcine model has been used for a long time together with other animal models for microsurgical training. Our study confirms and objective by validated scores that it is a valid and reliable model, comparable to the human one and which mimics the dissection of human perforating vessels.

Flaps of the abdominal wall

Objective: The deep inferior epigastric artery perforator (DIEP) and transverse-vertical rectus abdominis myocutaneous (TRAM, VRAM) flaps are derived from the anterior abdominal wall and can be free or pedicled. This study aimed to analyze the differences in postoperative complication rates among various types of abdominal flaps and to assess the impact of chemotherapy (CT) and radiotherapy (RT) on surgical outcomes. Materials and Methods: A retrospective study was conducted, analyzing abdominal flap operations performed between 2016 and 2023. Data on demographics, defect location, mesh use, and postoperative chemo-radiotherapy were collected. Quantitative variables were evaluated as means, minimum-maximum values, and categorical variables were assessed as percentages. Results: A total of 37 patients underwent 38 operations. Of these, nine patients had pedicled TRAM flaps, 16 had free-TRAM flaps, 6 had free DIEP flaps, and 6 had VRAM flaps. The defect locations were predominantly for breast reconstruction (81.08%), followed by head and neck (8.1%), extremity (8.1%), and thoracic wall (2.7%). The overall donor site complication rate was 5.4%, and the flap site complication rate was 13.51%. The lowest donor site complications were observed in the free-TRAM and VRAM groups (0%), while the highest were in the DIEP group (16.66%). The lowest flap site complication rate was 0% in the free-TRAM group, and the highest was 33.33% in the VRAM group. Donor site complication rates were similar between the mesh-used (5.88%) and non-mesh-used (5%) groups. All donor site complications occurred in patients who received postoperative CT and RT. Conclusion: Abdominal flaps were primarily utilized for breast reconstruction. The free-TRAM group exhibited the lowest donor and flap site complication rates, while the DIEP group had the highest donor site complication rates. Mesh use did not affect donor site complication rates. Postoperative administration of CT and RT was associated with increased donor site complications.

Ultrasound-guided preoperative skin-marking for deep inferior epigastric perforator flap surgery.

Deep inferior epigastric artery perforator (DIEP) flaps remain the gold standard of autologous breast reconstruction. However, the surgical technique entails a steeper learning curve and typically requires a higher mean surgical time, in part due to the time and effort involved in physical localization of appropriate perforators at the time of surgery. This is typically performed using Doppler ultrasound, and is a potentially challenging and time-consuming task in the hands of an untrained operator. In order to mitigate these challenges, ease time pressures, promote efficient utilization of our operating theatres and improve surgical outcomes, our institution routinely performs skin-marking in advance at the Breast Radiology department. In this article, we describe our technique and experience with the procedure.

Advances in Microsurgical Treatment Options to Optimize Autologous Free Flap Breast Reconstruction

Introduction: Reconstructive plastic surgeons have made great strides in the field of breast reconstruction to achieve the best results for patients undergoing treatment for breast cancer. As microsurgical techniques have evolved, these patients can benefit from additional treatment modalities to optimize the results of the reconstruction. Free tissue transfer from alternative donor sites for breast reconstruction is routinely performed, which was not possible in the past. Neurotization is now possible to address the numbness and lack of sensation to the reconstructed breast. For those patients who develop lymphedema of the upper extremity as a result of their breast cancer care, supermicrosurgical options are now available to treat and even to prevent the development of lymphedema. This study presents a narrative review regarding the latest microsurgical advancements in autologous free flap breast reconstruction. Methods: A literature review was performed on PubMed with the key words “autologous free flap breast reconstruction”, “deep inferior epigastric perforator flap”, “transverse upper gracilis flap”, “profunda artery perforator flap”, “superior gluteal artery perforator flap”, “inferior gluteal artery perforator flap”, “lumbar artery perforator flap”, “breast neurotization”, “lymphovenous bypass and anastomosis”, and “vascularized lymph node transfer”. Articles that specifically focused on free flap breast reconstruction, breast neurotization, and lymphedema surgery in the setting of breast cancer were evaluated and included in this literature review. Results: The literature search yielded a total of 4948 articles which were screened. After the initial screening, 413 articles were reviewed to assess the relevance and applicability to the current study. Conclusions: Breast reconstruction has evolved tremendously in recent years to provide the most natural and cosmetically pleasing results for those patients undergoing treatment for breast cancer. As technology and surgical techniques have progressed, breast cancer patients now have many more options, particularly if they are interested in autologous reconstruction. These advancements also provide the possibility of restoring sensibility to the reconstructed breast as well as treating the sequela of lymphedema due to their cancer treatment.

Optimizing Intraflap Anastomosis of Conjoined Bilateral DIEP Flap for Breast Reconstruction: Planning, Execution and Outcomes in 201 patients.

Conjoined bilateral deep inferior epigastric perforator (DIEP) flap with intraflap anastomosis is an efficient approach for breast reconstruction, enabling the use of almost the entire abdominal tissue. Variations in bilateral DIEA anatomy may make it challenging to apply this technique consistently. This study aimed to derive optimal strategies for achieving reliable conjoined bilateral DIEP flap with intraflap anastomosis universally. For all consecutive patients undergoing conjoined bilateral DIEP flap-based breast reconstruction from 2009 to 2023, preoperative planning and intraoperative execution for the pedicle configurations were reviewed. Their postoperative outcomes were evaluated. In total 201 patients were included, with no cases requiring conversion to extraflap anastomosis. In preoperative planning, candidates for recipient vessels for intraflap anastomosis were typically selected based on DIEA branching patterns, identified through computed tomographic angiography; Type I (single trunk) prioritizing the superior continuation, type II (two main trunks) considering a side branch, and type III (three main trunks) favoring the first bifurcating branch. Comparing candidates from bilateral DIEA, the primary pedicle was determined, providing larger recipient vessels. Most cases followed the planned approach smoothly, however 28 required intraoperative changes, mostly aimed at securing larger recipients by changing the primary pedicle or harvesting more caudally located perforators to obtain larger superior continuations. Four perfusion-related complications developed, which were resolved successfully without flap failure. Our results suggest an efficient strategy for securing a reliable recipient vessel, tailored to patient anatomy, in conjoined bilateral DIEP flap breast reconstruction with intraflap anastomosis, leading to achieving optimal outcomes.

DIEP Flap versus PAP Flap versus LAP Flap: A Propensity-Matched Analysis of Aesthetic Outcomes, Complications, and Satisfaction.

As free breast reconstruction options evolve, a patient- and body-centric approach can distinguish refined aesthetic outcomes. Although deep inferior epigastric perforator (DIEP), profunda artery perforator (PAP), and lumbar artery perforator (LAP) flaps are all safe and effective options for breast reconstruction, a head-to-head analysis of these 3 flaps has not been performed. The authors aim to compare these 3 flaps based on outcomes, BREAST-Q scores, and aesthetic results. After institutional review board approval, a retrospective review in a Research Electronic Data Capture database-guided analysis was conducted of patients who underwent simultaneous bilateral DIEP, PAP, or LAP flaps at a single academic institution. Propensity matching was performed to match 50 patients (100 flaps) in each group. Postoperative complications and BREAST-Q satisfaction survey scores were documented, and crowdsourcing was carried out to determine aesthetic preference in the general population. Overall patient postoperative breast satisfaction was insignificantly different across the 3 flap groups ( P > 0.05). Associations were seen with LAP flap donor-site seromas, PAP flap donor-site infections and wounds, and DIEP flap breast wounds and flap necrosis ( P < 0.05). DIEP flaps had a higher raw score average on crowdsourcing survey, although LAP flaps were rated significantly higher aesthetically than DIEP and PAP flaps when undergoing a matched head-to-head analysis ( P < 0.05). DIEP, PAP, and LAP flaps all have favorable outcomes with insignificantly different long-term satisfaction, with comparable complication profiles. Although DIEP flaps may initially score higher, LAP flaps score higher frequently when analyzed in a head-to-head analysis. For these reasons, tailoring breast reconstruction to the patient's anatomy and morphology provides optimal outcomes. Therapeutic, III.
