Background:  Autologous tissue has become the gold standard in breast reconstruction. The use of a deep inferior epigastric perforator (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 with the transverse rectus abdominis myocutaneous 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., Methods:  This was a retrospective cohort study collected from a prospective database maintained 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., Results:  Out of the 137 patients evaluated, there were 16 (11.67%) cases of revision, 14 (10.21%) were due to venous thrombosis. Twelve cases (8.75%) of flap loss were reported. Reoperation rate was lower in the dual venous drainage group when compared with 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)., Conclusion:  Dual venous drainage of a DIEP flap appears to reduce the rates of venous thrombosis, reoperation, total flap loss, and fat necrosis., Competing Interests: None declared., (Thieme.

Background and Purpose: Breast reconstruction following mastectomy is a relevant element of breast cancer treatment. The purpose of this study was to evaluate the influence of radiotherapy (RT) on local complications in patients with breast cancer that had undergone breast reconstruction with alloplastic material., Materials and Methods: Retrospective study of breast cancer patients submitted to mastectomy and breast reconstruction from 2009 to 2013. Clinical and treatment variables were correlated with early and late complications., Results: 251 patients were included; mean age was 49.7 (25 to 78) years. Reconstruction was immediate in 94% of the patients, with 88% performed with a temporary tissue expander. Postoperative radiotherapy (RT) was delivered to 167 patients (66.5%). Early complications were present in 26.3% of the patients. Irradiated patients presented 5.4% incidence of late complications versus 2.4% for non-irradiated patients (p = 0.327). Diabetes (OR = 3.41 95% CI: 1.23-9.45, p = 0.018) and high body mass index (BMI) (OR = 2.65; 95% CI: 1.60-4.37, p < 0.0001) were the main risk factors. The overall incidence of late complications was 4.4%, with predominance of severe capsular contracture (8/11). Arterial hypertension (OR = 4.78; 95% CI: 1.97-11.63, p = 0.001), BMI (OR = 0.170; 95% CI: 0.048-0.607, p = 0.006) and implant placement (OR = 3.55; 95% CI: 1.26-9.99, p = 0.016) were related to late complications., Conclusions: The overall rate of complications was low in this population. Radiotherapy delivery translated into a higher but not statistically significant risk of late complications when compared with the non-irradiated patients. Already well-known clinical risk factors for complications after breast reconstruction were identified., Competing Interests: Conflict of interest S.R.S., C.L.G.C., E.M., T.C.S.C., T.T.F., G.N.M., H.A.C. — none declared; A.M.M is a Member of the Medical Advisory Board, Establishment Labs., (© 2021 Greater Poland Cancer Centre.)

Background: Autologous fat grafting (AFG) has been employed in surgical practice as a filling method. However, controversies remain on the specifics of this technique. So far, few relevant experimental large animal studies have objectively assessed factors related to AFG integration., Objectives: This study utilized an experimental, medium-sized animal model to compare the feasibility of AFG collected employing 2 different techniques with instruments of distinct thicknesses., Methods: Twenty minipigs (Sus scropha domesticus) were subjected to AFG harvesting via en bloc resection utilizing 3- (Group I) and 5-mm-diameter (Group II) round punch blades (PBs) and liposuction (LS) with 3- (Group III) and 5-mm-diameter cannulas (Group IV). Both samples were grafted intramuscularly (biceps femoralis). Hematoxylin and eosin staining was employed to identify intact adipocytes, fat necrosis, fibrosis, inflammation, and oil cysts. Immunohistochemical staining (perilipin-A, tumor necrosis factor alfa, and cluster of differentiation number 31) was utilized to quantify the feasibility of adipocytes, tissue necrosis, and neoangiogenesis, respectively., Results: Hematoxylin and eosin analysis showed that fat necrosis and histiocyte presence were significantly lower in the AFG harvested utilizing a PB than in LS. For perilipin-A, a statistical difference was observed between subgroups I and III (P = 0.001) and I and IV (P = 0.004). Instrument diameter had no effect on graft integration in comparisons between groups II and III (P = 0.059) and II and IV (P = 0.132)., Conclusions: In this experimental study, fat collected utilizing a PB demonstrated higher adipocyte viability than fat collected with LS. The diameter of the collection instruments, whether PB or LS, had no effect on graft integration., (© 2020 The Aesthetic Society. Reprints and permission: journals.permissions@oup.com.)

We present an ultra-compact system approach for snapshot, multispectral imaging. It is based on a slanted linear variable spectral filter mounted in close proximity to the entrance pupil of a micro-optical, multi-aperture imaging system. A compact demonstration setup with a size of only 60 × 60 × 28 mm 3 is developed, which enables the acquisition of 66 spectral channels in a single shot and offers a linear spectral sampling of approximately six nanometers over an extended wavelength range of 450-850 nm. The spatial sampling of each channel covers up to 400 × 400 pixels. First, the concept, the optical design and the fabrication are detailed. After the optical performance characterization, a comprehensive calibration strategy is developed and applied. An experimental demonstration is performed by acquiring the spatial and the spectral information of an imaged test scene.

Objective: to evaluate the initial therapeutic experience of transplantation of vascularized lymph nodes in patients with lymphedema of the upper limbs secondary to the treatment of breast cancer, and to verify if the positioning of the transplant influences the surgical result., Methods: we conducted a prospective, comparative test of two therapeutic modalities, with 24 patients with lymphedema of the upper limb after breast cancer treatment, classified as grades 2 and 3, according to the International Lymphedema Society. The two types of procedures performed were: 1) total breast reconstruction with - deep inferior epigastric perforator (DIEP) flap associated with lymph node flap, in patients with no previous breast reconstruction or loss of previous reconstruction (axillary positioning); 2) isolated inguinal lymph node flap performed in patients with completed breast reconstruction or without the desire to perform the breast reconstruction (wrist positioning)., Results: the reduction percentage of the affected limb volume was 20.1% (p=0.0370). The number of infectious episodes (cellulites) also decreased significantly, from 41% in the preoperative period to 12.5% in the postoperative one (p=0.004). There were no differences between the proximal and distal groups., Conclusion: the transplantation of lymph nodes positively affected the postoperative evolution of patients with lymphedema secondary to breast cancer. We observed no differences in relation to flap positioning.

Background: Implant-based breast reconstruction (IBR) is the most common approach to reconstruct mastectomy deffects. Infection following breast reconstruction can be devastating and lead to loss of the reconstruction due to the need of implant removal. The serratus anterior muscle flap is widely used during breast reconstruction to provide coverage of the implant/expander., Methods: We present the application of the serratus anterior muscle flap to treat implant exposure after breast reconstruction., Cases Presentation: Two patients who experienced implant exposure after breast reconstruction were successfully treated with partial capsulectomy, pocket irrigation and implant coverage with a serratus anterior muscle flap., Results: No post operative complications have been observed while implant retention was achieved in both cases., Conclusions: The serratus anterior muscle flap is an option to treat implant exposure following breast reconstruction in selected cases. This flap could be used to prevent implant exposure in critical cases., (Copyright © 2019. Published by Elsevier Ltd.)

Objective: to evaluate the role of age in the risk of postoperative complications in patients submitted to unilateral breast reconstruction after mastectomy, with emphasis on total reconstruction loss., Methods: we conducted a retrospective study of patients submitted to breast reconstruction, whose variables included: oncological and reconstruction data, postoperative complications, including loss of reconstruction and complications of surgical wound. We divided the patients into two groups, according to the classification of the Brazilian National Elderly Policy and the Statute of the Elderly: young (age <60 years) and elderly (60 years or more). We also grouped them according to the World Health Organization classification: young people (age <44 years), middle age (45-59 years); elderly (age 60-89 years) and extreme advanced age (90 years or older). We applied the surgical risk classification of the American Society of Anesthesiologists to investigate the role of the preoperative physical state as a possible predictor of complications., Results: of the 560 patients operated on, 94 (16.8%) were 60 years of age or older. We observed a local complication rate of 49.8%, the majority being self-limited. The incidences of necrosis, infection and dehiscence were 15.5%, 10.9% and 9.3%, respectively. Patients older than 60 years presented a chance of complication 1.606 times greater than the younger ones. Forty-five (8%) patients had loss of the reconstruction; there was no statistically significant difference in the mean age of the patients who presented this result or not (p=0.321)., Conclusion: in selected patients, breast reconstruction can be considered safe; most documented complications were limited and could be treated conservatively.

Background: Flap coverage is the gold standard in treating pressure sores, and due to the high recurrence rate, the possibility of multiple surgical procedures should be considered during flap selection. The gluteal thigh (GT) flap has become a workhorse for ischiatic pressure sore treatment at our hospital. Follow-up revealed a group of patients presenting recurrence of the pressure sore that needed a second flap. The inferior gluteal artery perforator (IGAP) flap was chosen in this series. The positive experience with both flaps raised the question of which flap should be the first option for the treatment of ischiatic and perineal pressure sores., Methods: IGAP and GT flaps were dissected in 21 fresh human cadavers to allow comparison of anatomical features. In a series of 60 patients, the authors used both the gluteal thigh and the IGAP flap to cover 76 ischiatic and perineal ulcers., Results: The IGAP flap was found to be wider and thicker than the gluteal thigh, but presented a shorter pedicle. All flaps healed uneventfully. Recurrent ulcers were treated successfully with both flaps., Conclusions: Both flaps are suitable for coverage ischiatic and perineal sores. Due to its anatomical features, the IGAP flap should be considered the first choice of treatment for ischiatic ulcers. The gluteal thigh flap should be used in the recurrent sores.Level of Evidence: Level IV, therapeutic study., Competing Interests: Compliance with ethical standardsEduardo Montag, Thiago Ueda, Alberto Okada, Bruno Onishi, and Rolf Gemperli declare that they have no conflict of interest.For this type of retrospective study formal consent from a local ethics committee is not requiredInformed consent was obtained prior to surgical procedures according to the rules of HCFMUSP.Patients provided written consent for the use of their images.

Background: Unsuccessful breast reconstruction management represents a complex challenge for the plastic surgeon. Although these events rarely occur, many patients are not suitable candidates for conventional flaps, because of either previous donor-site surgery or lack of sufficient tissue., Methods: In this study, a contralateral free latissimus dorsi musculocutaneous flap (CL-LDMF) was planned for correction of major lesions in the anterior chest wall. Twelve patients underwent secondary/tertiary breast reconstruction with CL-LDMF with a customized shape (horizontal, oblique, or "fleur-de-lis") depending on the amount of tissue necessary. The technique was indicated in patients with large thoracic defects who lacked a donor site and had undergone previous unsuccessful pedicled LDMF., Results: The mean follow-up time was 42.5 months (range: 18-72 months). Five local complications occurred in four of the 12 patients. Dorsal dehiscence was observed in one, local wound infection in one, small partial CL-LDMF necrosis in one, and dorsal seroma in one patient. All cases of complications were limited and treated with a conservative approach except for one implant extrusion 4 months after reconstruction. No total flap loss was reported. All patients achieved a satisfactory thoracic and breast reconstruction., Conclusion: The results of this study demonstrate that free CL-LDMF is a reliable technique and should be considered in selected cases of tertiary reconstructions. The majority of complications were immediate, minor, and comparable to other reconstructive techniques. We believe that in selected patients, especially those who do not have available donor-site areas, free CL-LDMF is advantageous and should be part of the armamentarium of all plastic surgeons who deal with tertiary breast reconstructions., (Copyright © 2016 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Nipple-sparing mastectomy (NSM) is a safe technique in patients who are candidates for conservation breast surgery. However, there is worry concerning its oncological safety and surgical outcome in terms of postoperative complications. The authors reviewed the literature to evaluate the oncological safety, patient selection, surgical techniques, and also to identify the factors influencing postoperative outcome and complication rates. Patient selection and safety related to NSM are based on oncological and anatomical parameters. Among the main criteria, the oncological aspects include the clinical stage of breast cancer, tumor characteristics and location including small, peripherally located tumors, without multicentricity, or for prophylactic mastectomy. Surgical success depends on coordinated planning with the oncological surgeon and careful preoperative and intraoperative management. In general, the NSM reconstruction is related to autologous and alloplastic techniques and sometimes include contra-lateral breast surgery. Choice of reconstructive technique following NSM requires accurate consideration of various patient related factors, including: breast volume, degree of ptosis, areola size, clinical factors, and surgeon's experience. In addition, tumor related factors include dimension, location and proximity to the nipple-areola complex. Regardless of the fact that there is no unanimity concerning the appropriate technique, the criteria are determined by the surgeon's experience and the anatomical aspects of the breast. The positive aspects of the technique utilized should include low interference with the oncological treatment, reproducibility, and long-term results. Selected patients can have safe outcomes and therefore this may be a feasible option for early breast cancer management. However, available data demonstrates that NSM can be safely performed for breast cancer treatment in selected cases. Additional studies and longer follow-up are necessary to define consistent selection criteria for NSM.

Recently breast surgeons can offer patients a variety of treatment and reconstructive alternatives when early breast cancer is diagnosed. In fact, advances in reconstructive techniques have reduced surgical trauma and thus are capable of preserving the breast form as well as quality of life. Depending on a variety of different factors, including stage, tumor size, location, hystological type, but also breast volume, a reconstructive schedule is established. The main techniques are related to volume displacement or replacement procedures including local flaps, latissimus dorsi myocutaneous flap and reduction mammaplasty/ masthopexy. Regardless of the fact that there are is no consensus over the best approach, the criteria are determined by the surgeon's experience and the size of the defect in relation to the size of the remaining breast. Aim of every reconstructive procedure decision should be breast preservation and an adequate aesthetic outcome. Additionally, reconstruction permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reducing the incidence of margin involvement. The objective of this review is to give an overview of reconstructive modalities for conservative breast surgery, based not only on traditional but also on the latest studies regarding the outcome of the main techniques employed. Surgical approaches, as well as conservative treatment options, such as lumpectomy and quadrantectomy, are further discussed. Surgical planning should include the patients' preferences, while chiefly addressing individual reconstructive requirements, and enabling each patient to receive an individual "custom-made" reconstruction.

Background: In microsurgical breast reconstruction, an adequate selection of recipient vessels is crucial for a successful outcome. Although the internal mammary (IM) vessels offer an attractive option, the internal mammary perforator (IMP) vessels are becoming a reliable alternative. The purpose of this study is to investigate the external diameters, lumen area, and atherosclerotic lesions changes of the IMP, IM, and deep inferior epigastric (DIE) vessels through quantitative and qualitative histomorphometric analysis., Methods: Ninety-six vessels of bilateral IM, IMP, and DIE vessels from 16 fresh female cadavers were evaluated. Mean age was 54.06 ± 5.7 years. External diameters, lumen area, and degenerative changes of the tunica intimae and media were analyzed by qualitative histomorphometric analysis., Results: Seventy-one vessels (20 IM, 31 IMP, and 20 DIE vessels) were included in the final histological analysis. A statistically lower external diameters and lumen area were presented by the IMP. The DIE vessels showed a lower incidence (10%) of moderate and severe intimal layer degenerative changes (P = 0.0589). The IMP and DIE vessels showed a lower incidence (9.4 and 25%, respectively) of major media layer degenerative changes (P = 0.0001). No major arterial degenerative lesions were observed in the IMP arteries., Conclusion: Although the IMP external diameters and lumen area were lower than the IM, the results of this study indicated that the tunica media layer in the IMP is less damaged than the other recipient vessels. The results of the comparative histological study permitted to describe additional advantages and disadvantages of using IMP as a recipient vessel for free flap breast reconstruction., (© 2013 Wiley Periodicals, Inc.)

Breast-conservation surgery (BCS) is established as a safe surgical treatment for most patients with early breast cancer. Recently, advances in oncoplastic techniques are capable of preserving the breast form and quality of life. Although most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Among technical options, therapeutic reduction mammaplasty (TRM) remains a useful procedure since the BCS defect can be repaired and the preoperative appearance can be improved, resulting in more proportional breasts. As a consequence of rich breast tissue vascularization, the greater part of reduction techniques have based their planning on preserving the pedicle of the nipple-areola complex after tumor removal. Reliable circulation and improvement of a conical shape to the breast are commonly described in TRM reconstructions. With an immediate approach, the surgical process is smooth since both procedures can be carried out in one operative setting. Additionally, it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reduces the incidence of margin involvement. Regardless of the fact that there is no consensus concerning the best TRM technique, the criteria is determined by the surgeon's experience, the extent/location of glandular tissue resection and the size of the defect in relation to the size of the remaining breast. The main advantages of the technique utilized should include reproducibility, low interference with the oncological treatment and long-term results. The success of the procedure depends on patient selection, coordinated planning and careful intra-operative management.

Introduction: Lumbar triangle hernia after breast reconstruction with latissimus dorsi flap (LDMF) is a very rare complication and few cases were previously described. Muscle mobilization and iatrogenic fascia defect are related etiologic factors., Presentation of Case: The authors describe a rare case of lumbar hernia in a 58-year-old woman who underwent delayed left breast reconstruction with LDMF. Two months after surgery, a progressive symptomatic lower left lumbar bulge was observed. The CT scan confirmed the diagnosis and delineated an 18cm lumbar defect filled with lower and large bowel. At operation, the defect was exposed and the hernia sac reduced. In order to obtain stability, the remained local muscle and fascia flaps were mobilized into the defect. Additional strength was achieved with a two-layer closure of prosthetic mesh (intra/extra peritoneal). The patient is currently in the 10th postoperative year of hernia repair and satisfactory lumbar wall contour was achieved. Neither the recurrence of lumbar hernia nor symptoms compliance was noted., Discussion: Lumbar hernia is an uncommon complication of LDMF harvest. Although it is a rare disease, general and plastic surgeons must be on alert to avoid complications and misdiagnosis. Seroma differential diagnosis is important in order to avoid bowel perforation due to aspiration. Defect reconstruction is necessary with a muscular and fascia flaps mobilization and synthetic mesh in order to obtain a stable repair., Conclusion: The knowledge of this rare post-operative complication following delayed breast reconstruction is crucial to its surgical management. Early surgical intervention is warranted in order to avoid severe complications., (Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Background: Breast sarcoma during pregnancy is an extremely rare event and represents a complex problem because of a more advanced stage at presentation., Method: This report presents the first case of a 24-year-old woman with a gestational age of 20 weeks with a fast growing tumour in her left breast (29 × 19 × 15 cm) and infiltrating the skin/pectoralis muscles. Radical mastectomy was performed with a gestational age of 22 weeks and a different design was planned for the latissimus dorsi musculocutaneous flap (LDMF) with primary closure in the V-Y pattern., Result: Satisfactory chest wall coverage and contour were achieved. Final histopathological findings allowed a diagnosis of undifferentiated sarcoma. With a gestational age of 37 weeks, a healthy infant was delivered by means of a caesarean section. The patient is currently in the second postoperative year and no recurrence has been observed., Conclusion: Management of a large breast sarcoma in a pregnant patient presents unique challenges in consideration of the potential risks to the foetus and the possible maternal benefit. The results of this study demonstrate that the VY-LDMF is a reliable technique and should be considered in cases of immediate large thoracic wound reconstruction., (Copyright © 2013 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

It has been suggested that the abrupt liposuction-induced decrease in adipose tissue could affect adipokine secretion pattern. We hypothesized that exercise training could positively impact adipokine metabolism following liposuction. The aim of this study was to investigate the effects of liposuction on inflammation-related adipokines in women who were either exercise-trained or remained sedentary after surgery. Thirty-six healthy normal-weight women underwent an abdominal liposuction and two months after surgery were randomly allocated into two groups: trained (TR, n = 18, four-month exercise program) and nontrained (NT, n = 18). Inflammation-related adipokine serum levels (TNF- α , IL-6, IL-10, and adiponectin) and abdominal and thigh subcutaneous adipose tissue (scAT) mRNA levels were assessed before (PRE) and six months after surgery (POST6). TNF- α , IL-6, and IL-10 serum levels were unchanged in both groups. In contrast, TNF- α , IL-6, and IL-10 mRNA levels in scAT were increased, whereas adiponectin scAT mRNA and serum levels were decreased at POST6 (P < 0.05, main effect for time). No changes were observed in mRNA levels of MCP-1, CD14, and CD68 in any of the groups. In conclusion, liposuction downregulates adiponectin scAT gene expression and serum levels and upregulates scAT gene expression of inflammation-related genes six months after surgery in normal-weight women, irrespective of exercise training.

Breast-conservation surgery (BCS) is established as a safe option for most women with early breast cancer. Recently, advances in oncoplastic techniques have reduced surgical trauma and thus are capable of preserving the breast form and quality of life. In spite of the most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Oncoplastic reconstruction may begin at the time of BCS (immediate), weeks (delayed-immediate) or months to years afterwards (delayed). With immediate reconstruction, the surgical process is smooth, since both procedures can be associated in one operative setting. Additionally, it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reducing the incidence of margin involvement. The oncoplastic techniques are related to volume displacement or replacement procedures including local flaps, latissimus dorsi myocutaneous flap and reduction mammaplasty/masthopexy. Regardless of the fact that there is no consensus concerning the best approach, the criteria are determined by the surgeon's experience and the size of the defect in relation to the size of the remaining breast. On the basis of our 15-year experience, it is possible to identify trends in types of breast defects and to develop an algorithm for immediate BCS reconstruction on the basis of the initial breast volume, the extent/location of glandular tissue ressection and the remaining available breast tissue. The main advantages of the technique utilized should include reproducibility, low interference with the oncologic treatment and long-term results. Surgical planning should include the patients's preferences, and chiefly addressing individual reconstructive requirements, enabling each patient to receive an individual "custom-made" reconstruction.

Nipple-sparing mastectomy (NSM) is increasingly offered to women for therapeutic and prophylactic indications. Although, clinical series have been described, there are few studies describing risk factors for complications. The objective of this study is to evaluate the incidence of complications in a series of consecutive patients submitted to NSM and differences between clinical risk factors, breast volume, and different incision types. In a cohort-designed study, 158 reconstructed patients (invasive/in situ cancer and high risk for cancer) were stratified into groups based on different types of incision used (hemi-periareolar, double-circle periareolar, and Wise-pattern). They were matched for age, body mass index, associated clinical diseases, smoking, and weight of specimen. Also included were patients treated with adjuvant chemotherapy and postoperative radiotherapy. Mean follow-up was 65.6 months. In 106 (67 %) patients, NSM was performed for breast cancer treatment and in 52 (32.9 %) for cancer prophylaxis. Thirty-nine (24.6 %) patients were submitted to hemi-periareolar technique, 67 (42.4 %) to double-circle periareolar incision, and 52 (33 %) to Wise-pattern incision. The reconstruction was performed with tissue expander and implant-expander. Local recurrence rate was 3.7 % and the incidence of distant metastases was 1.8 %. Obese patients and higher weight of specimen had a higher risk for complications. After adjusting risk factors (BMI, weight of specimen), the complications were higher for patients submitted to hemi-periareolar and Wise-pattern incisions. This follow-up survey demonstrates that NSM facilitates optimal breast reconstruction by preserving the majority of the breast skin. Selected patients can have safe outcomes and therefore this may be a feasible option for breast cancer management. Success depends on coordinated planning with the oncologic surgeon and careful preoperative and intraoperative management. Surgical risk factors include incision type, obesity, and weight of breast specimen.

Context: Liposuction is suggested to result in long-term body fat regain that could lead to increased cardiometabolic risk. We hypothesized that physical activity could prevent this effect., Objective: Our objective was to investigate the effects of liposuction on body fat distribution and cardiometabolic risk factors in women who were either exercise trained or not after surgery., Design, Setting, and Participants: Thirty-six healthy normal-weight women participated in this 6-month randomized controlled trial at the University of Sao Paulo, Sao Paulo, Brazil., Interventions: Patients underwent a small-volume abdominal liposuction. Two months after surgery, the subjects were randomly allocated into two groups: trained (TR, n = 18, 4-month exercise program) and nontrained (NT, n = 18)., Main Outcome Measures: Body fat distribution (assessed by computed tomography) was assessed before the intervention (PRE) and 2 months (POST2), and 6 months (POST6) after surgery. Secondary outcome measures included body composition, metabolic parameters and dietary intake, assessed at PRE, POST2, and POST6, and total energy expenditure, physical capacity, and sc adipocyte size and lipid metabolism-related gene expression, assessed at PRE and POST6., Results: Liposuction was effective in reducing sc abdominal fat (PRE vs. POST2, P = 0.0001). Despite the sustained sc abdominal fat decrement at POST6 (P = 0.0001), the NT group showed a significant 10% increase in visceral fat from PRE to POST6 (P = 0.04; effect size = -0.72) and decreased energy expenditure (P = 0.01; effect size = 0.95) when compared with TR. Dietary intake, adipocyte size, and gene expression were unchanged over time., Conclusion: Abdominal liposuction does not induce regrowth of fat, but it does trigger a compensatory increase of visceral fat, which is effectively counteracted by physical activity.

Background: Breast reconstruction with autogenous tissue is a well-established technique, but there are some limitations related to donor-site morbidity. Among available techniques, the superficial inferior epigastric artery (SIEA) flap is the least invasive procedure because it does not require harvesting or incision of the rectus muscle or the abdominal fascia. Besides adequate flap choice, the proper selection of the recipient vessels is an important factor. Thus, the internal mammary perforator branches (IMPBs) have been an attractive option regarding recipient pedicle morbidity., Methods: The investigators reported the use of the free SIEA flap with the IMPBs as a recipient site to reconstruct radical mastectomy., Results: Five patients with invasive ductal carcinoma underwent modified radical mastectomy and reconstruction. The IMPBs were selected as the recipient site and a free SIEA flap was used. The donor defect was closed directly without synthetic mesh. Satisfactory breast shape was achieved, and no complications were observed., Conclusions: For selected patients, the SIEA flap and IMPBs may constitute a new alternative for immediate breast reconstruction, because of the possibility of large tissue transfer with minimal donor and recipient area morbidity. The SIEA pedicle size and the quality of IMPB vessels should be carefully evaluated., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Background: Bilateral mammaplasty or mastopexy is frequently used for oncoplastic objectives. However, little information has been available regarding outcome following immediate and delayed reconstruction., Method: Patients were divided into Group I (immediate reconstruction) and Group II (delayed reconstruction). Retrospective review was performed to compare complications, length of hospital stay, revision surgeries, and satisfaction. The associations between the complications with potential risk factors (timing, age, body mass index, smoking, and comorbid medical conditions) were analyzed., Results: There were a total of 144 patients with a mean follow-up of 47 months. Of the 106 patients in Group I, complications occurred in 24 (22.6%), skin necrosis was observed in 7.5%, fat necrosis in 5.6%, and 6.6% patients developed local recurrence. Mean period of hospitalization was 1.89 days. Of the 38 patients of the Group II, complications occurred in 12 (31.5%), skin necrosis was observed in 7 (18.4%), fat necrosis in 4 (10.5%), and 5.2% patients developed local recurrence. Mean period of hospitalization was 1.35 days. Increased length of hospital stay greater than 1 day (P < 0.001) and the number of revision surgeries (P = 0.043) were associated with the timing of the reconstruction. In univariate analysis, no difference between groups was found with respect to complication incidence (P = 0.275); however, after adjusting for other risk factors, the probability of complications tend to be higher for Group II (OR = 2.65; 95% confidence interval = 1.01-7.00; P = 0.049)., Conclusions: On the basis of the results of our study, the probability of complications tends to be higher for delayed reconstructions, and it is demonstrated that obesity and smoking are risk factors for complications. Ultimately, these data may facilitate the provision of individualized risk information for shared medical decision-making.

Introduction: Although the use of local flaps in conservative breast surgery (CBS) reconstruction is a reliable technique, little information has been available regarding outcome following the use of perforator flaps. The purpose of this study is to analyze the feasibility, surgical planning and outcome following CBS reconstruction with intercostal artery perforator (ICAP) flap., Patients/methods: Thirteen patients underwent CBS reconstructions with an ICAP flap. These flaps were raised from adjacent tissue located on the lateral and thoracic region and based on perforators originating from the costal and muscular segment of the intercostal vessels. The technique was indicated in patients with small/moderate volume breasts., Results: Mean time of follow-up was 32 months. Flap complications were evaluated and information on patient satisfaction were collected. 61.5 percent had tumors located in the lower-outer quadrants and 69.2 percent had tumors measuring 2 cm or less (T1). Complications occurred in 3 patients (23%), including wound dehiscence in 2 patients and fat necrosis in one. All cases were treated by conservative approach with a good result. No flap loss or wound infection were reported. 90 percent were either satisfied or very satisfied with their result., Conclusion: The ICAP flap is a reliable technique for immediate CBS reconstruction. The technique is advantageous because it does not require the use of muscle transfer, with minimum donor site morbidity.

Background: Surgical resection in locally advanced breast cancer produces large defects that may not be suitable for primary closure. Immediate reconstruction is controversial and presents a complicated scenario for breast surgeons and plastic surgeons., Methods: In this study, a different design was planned for the latissimus dorsi musculocutaneous flap with primary closure in V-Y for the correction of major lesions in the anterior chest wall. Twenty-five patients underwent immediate locally advanced breast cancer reconstruction with a V-Y latissimus dorsi musculocutaneous flap. This flap was raised from adjacent tissue located on the lateral and posterior thoracic region and presented a triangular shape whose base was the lateral aspect of the mastectomy wound. The technique was indicated in patients with large thoracic wounds., Results: Mean follow-up time was 16 months. Closure was obtained in the donor and recipient sites without the use of skin grafts or other more major procedures. Complications occurred in nine patients (36 percent), including dorsal wound dehiscence in five patients and seroma in three. All cases except one were treated by a conservative approach with a good result. No total flap loss was reported. All patients achieved a satisfactory thoracic reconstruction and adequate wound care., Conclusions: The V-Y latissimus dorsi musculocutaneous flap is a reliable technique for immediate locally advanced breast cancer reconstruction. The technique is advantageous because the V-Y design allows primary closure of the chest wound and donor defect. Success depends on patient selection, coordinated planning with the breast cancer surgeon, and careful intraoperative management.

Although the biodimensional anatomical expander-implant system (BEIS) is a reliable technique, little information has been available regarding outcome following nipple-areola sparing mastectomy (NSM). To perform the resection of glandular tissue, while improving the surgical access and maintaining the nipple-areola vascularization we have developed a new approach for NSM based on the double concentric periareolar incision (DCPI). The purpose of this study is to analyze the feasibility, surgical planning and its outcome following NSM. 18 patients underwent NSM reconstructions. Mean time of follow-up was 29 months. The technique was indicated in patients with small/moderate volume breasts. Flap complications were evaluated and information on aesthetic results and patient satisfaction were collected. 83.3% had tumors measuring 2cm or less (T1) and 72.1% were stage 0 and I. All patients presented peripherally tumors located (at least 5cm from the nipple). Skin complications occurred in 11.1%. One patient (5.5%) presented small skin necrosis and a wound dehiscence was observed in one patient (5.5%). The aesthetic result was good/very good in 94.4 percent and the majority of patients were very satisfied/satisfied. No local recurrences were observed. All complications except one were treated by a conservative approach. DCPI-BEIS is a simple and reliable technique for NSM reconstruction. The success depends on patient selection, coordinated planning with the oncologic surgeon and careful intra-operative and post-operative management.

The efficacy of breast-conserving surgery for the local control of early breast cancer has been repeatedly evidenced. Although immediate reconstruction following breast-conserving surgery has been described, little information is available regarding surgical management in reoperative settings due to positive margins. We studied the influence of intraoperatively assessed and postoperatively controlled surgical margin status on the type of breast-conserving surgery and report our results regarding complications in a reoperative breast reconstruction scenario. All patients were seen by a multidisciplinary team who recommended breast-conserving surgery. According to the breast volume, ptosis and tumor size/location, the patients were also evaluated by a plastic surgeon, who recommended reconstruction with the appropriate technique. Intraoperative assessment of surgical margins was determined by histological examination of frozen sections. The mean follow-up time was 48 months. Two hundred and eighteen patients (88.5%) underwent breast-conserving surgery and immediate reconstruction. Twelve (5.5%) patients had a positive tumor margin after review of the permanent section. All patients underwent re-exploration. In 1.3%, a second reconstructive technique was indicated and in 2.2% a skin-sparing mastectomy with total reconstruction was performed. Our findings support the important role of the intraoperative assessment of surgical margins and its interference in the selection of reconstruction techniques and negative margins; however, it will not guarantee complete excision of the tumor. Success depends on coordinated planning with the oncologic surgeon and careful intraoperative management.

Background: Surgical treatment of lower extremity fractures commonly involves the use of orthopedic table with perineal post for countertraction. However, prolonged application of the perineal post has been associated with significant complications. We describe our experience in the management of genitoperineal cutaneous injuries associated with the use of a traction table., Methods: Six patients with genitoperineal complications attributed to the use of a traction table were treated at our institution over a period of 2 years. The patient's median age was 25 (range, 20-28) years and all had fractures caused by motor vehicle collision. We evaluated the clinical presentation of these perineal injuries, operative time, therapeutic approach, clinical outcomes, and hospitalization time., Results: The mean operative time of the orthopedic surgery was 318 minutes +/- 128 minutes (range, 185-540). All patients developed a partial-thickness necrotic area involving the perineum and scrotum in 2 days to 15 days (mean, 7 +/- 5.4) after the surgery. Three patients developed infection of the necrotic tissue. All patients underwent surgical debridement 16.5 days +/- 6.5 days (range, 13-29) after the orthopedic surgery and only one debridement procedure was necessary in all cases. A primary wound closure was possible in one case, and in the other cases the wound healed completely by second intention. The mean hospitalization time was 26.3 days +/- 9.7 days (range, 19-44)., Conclusion: Genitoperineal skin necrosis induced by perineal traction posttable is a morbid complication that demands surgical debridement and prolonged hospitalization for your treatment. There are many procedures available to reduce the risk of this complication that should be used more liberally by the orthopedic surgeons.

Background: Although various techniques have been used for breast conservation surgery reconstruction, there are few studies describing a logical approach to reconstruction of these defects. The objectives of this study were to establish a classification system for partial breast defects and to develop a reconstructive algorithm., Methods: The authors reviewed a 7-year experience with 209 immediate breast conservation surgery reconstructions. Mean follow-up was 31 months. Type I defects include tissue resection in smaller breasts (bra size A/B), including type IA, which involves minimal defects that do not cause distortion; type IB, which involves moderate defects that cause moderate distortion; and type IC, which involves large defects that cause significant deformities. Type II includes tissue resection in medium-sized breasts with or without ptosis (bra size C), and type III includes tissue resection in large breasts with ptosis (bra size D)., Results: Eighteen percent of patients presented type I, where a lateral thoracodorsal flap and a latissimus dorsi flap were performed in 68 percent. Forty-five percent presented type II defects, where bilateral mastopexy was performed in 52 percent. Thirty-seven percent of patients presented type III distortion, where bilateral reduction mammaplasty was performed in 67 percent. Thirty-five percent of patients presented complications, and most were minor., Conclusions: An algorithm based on breast size in relation to tumor location and extension of resection can be followed to determine the best approach to reconstruction. The authors' results have demonstrated that the complications were similar to those in other clinical series. Success depends on patient selection, coordinated planning with the oncologic surgeon, and careful intraoperative management.

The objective of this study is to describe the surgical planning of the inferior dermoglandular pedicle (IDP) technique and its outcome following partial mastectomy reconstruction. A total of 26 patients with breast cancer underwent immediate IDP reconstruction. IDP was indicated to reconstruct superior/central breast defects. Postoperative complications were evaluated and information on esthetic result and satisfaction were collected. About 57.6 percent had tumors measuring 2cm or less (T1). Immediate complications occurred in 34.2 percent with skin necrosis in 11.4 and dehiscence in 7.6 percent. Late complications were observed in 11.4 percent. The cosmetic result was considered to be good or very good in 88.4 percent and the majority of patients were satisfied. All complications were treated by conservative approach. IDP is a reliable technique and should be given consideration in cases of superior/central quadrant reconstruction. The success of the procedure depends on patient selection and careful intra-operative management.

Although breast reconstruction with deep inferior epigastric perforator (DIEP) flap is a well-described technique, few publications have specifically reported the technical aspects and the outcome following skin-sparing mastectomy (SSM). The aim of this study is to analyse the feasibility of its immediate application and to describe the operative planning, outcome and complications after SSM. 27 patients underwent 30 DIEP flap breast reconstructions with all immediate and 3 bilateral. Mean time of follow-up was 29 months. Breast skin, DIEP Flap and donor-site complications were evaluated. Information on patient satisfaction was collected. 70% had tumors measuring 2 cm or less (T1) and 74% were stage 0 and I according to American Joint Committee on Cancer. Breast skin complications occurred in 7.4%, all represented by small areas of skin necrosis. Partial losses were observed in two (7.4%) patients (less than 15% of total area) and total DIEP loss in 1 (3.7%). Donor-site complications represented by bulging occurred in only one patient (3.7%). The majority of patients were either very satisfied or satisfied. One local recurrence was observed. All complications except 2 were treated by a conservative approach. The DIEP flap is a reliable technique for SSM reconstruction. Success depends on patient selection, coordinated planning with the oncologic surgeon and careful intraoperative and postoperative management. The main advantage is that patients can safely undergo dual procedures with the added aesthetic benefits in breast and abdominal donor site.

Background: Although use of the latissimus dorsi myocutaneous flap associated with the Biodimensional anatomical expander implant system (McGhan 150) is a reliable technique, little information has been available regarding clinical outcome following periareolar skin-sparing mastectomy reconstruction. The purpose of this study was to analyze the feasibility of the technique, surgical planning, and its outcome following skin-sparing mastectomy., Methods: Thirty-two patients underwent immediate unilateral latissimus dorsi myocutaneous flap/Biodimensional anatomical expander implant system breast reconstruction. Mean follow-up was 18 months. The technique was indicated in patients with small- or moderate-volume breasts with or without ptosis, in whom the use of abdominal flaps was precluded. Flap and donor-site complications were evaluated. Information on anesthetic results and patient satisfaction was collected., Results: Seventy-two percent had tumors measuring 2 cm or less (T1) and 78 percent were stage 0 and I according to American Joint Committee on Cancer criteria. Breast skin complications occurred in 9.4 percent. Two patients presented small breast skin necrosis, and in one patient, a wound dehiscence was observed. Donor-site complications, all represented by seroma, occurred in 12.5 percent. The cosmetic result was considered good or very good in 84.4 percent, and the majority of patients were either very satisfied or satisfied. No local recurrences were observed. All complications except two were treated by conservative means., Conclusions: The latissimus dorsi myocutaneous flap/Biodimensional anatomical expander implant system is a simple and reliable technique for periareolar skin-sparing mastectomy reconstruction. Success depends on patient selection, coordinated planning with the oncologic surgeon, and careful intraoperative and postoperative management.

Background: The transaxillary approach plays a useful role for breast augmentation due to scar placement in a less visible position. However, the future impact of the procedure on the lymphatic drainage patterns and sentinel lymph node (SLN) detection remains controversial. To date, no information is available regarding the feasibility of SLN identification in patients with previous transaxillary breast augmentation (TBA)., Methods: Twenty-six patients underwent primary TBA. Mean follow-up was 8.3 months. All patients were submitted to lymphoscintigraphy (LSG), with a dose of 0.1 mCi 99m-technetium-labeled dextran 1 week before (preop-LSG) and 10 days (Po10 days-LSG) after TBA., Results: Preop-LSG was successful in all patients. Mean number of SLN detected was 2 per patient (range, 1 to 4) in the right axilla and 2.2 (range, 1 to 5) in the left. In Po10 days-LSG, SLN detection was successful in 92.3%. Mean number of SLN detected was 2.3 per patient (range, 0 to 7) in the right axilla and 1.8 (range, 0 to 6) on the left. Two patients (7.6%) failed to reveal the accumulation of radioactivity in Po10 days-LSG. Comparing bilaterally, in the number of SLN detected (P = 0.838) and the SLN uptake (P = 0.067) between Preop-LSG and Po10 days-LSG, no significant differences were observed. No major complication was noted., Conclusion: The initial data illustrate that SLN detection in the setting of prior TBA is feasible in a great part of patients. Additional long-term studies are necessary to investigate the accuracy of SLN biopsy in subgroups of breast cancer patients with previous breast implants.

Breast radiotherapy during childhood may cause unpredictable outcomes in soft tissue growth and may be responsible for most iatrogenic-related breast hypoplasias. Poor local skin quality and subcutaneous atrophy poses a difficult problem for the use of alloplastic tissues. Clinical use of a deep inferior epigastric perforator flap (DIEP) in oncological breast surgery is a common practice; however few studies have described its application in benign situations and no previous report addressed this subject. The authors indicate the use of the DIEP flap to correct severe hypomastia after previous childhood radiotherapy for hemangioma treatment, followed by unsuccessful alloplastic tissue reconstruction. For selected patients the DIEP flap may constitute a new alternative for complications of radiotherapy treatment due to the possibility of large tissue transfer with minimal donor area morbidity. The quantity of flap tissue necessary to restore the breast mound, the perforator vessel size, and the quality of suitable recipient vessels should be carefully evaluated. However, the need for microsurgical training as well as the extended surgical time are the main limiting factors for the use of this flap.

Background: Reduction mammaplasty procedures and especially the superior-medial dermoglandular pedicle (SMDP) technique are frequently used for esthetic objectives; however, few reports have been available regarding its application following conservative breast surgery reconstruction. The purpose of this study is to analyze the feasibility of the technique and describe the surgical planning and its outcome following oncologic surgery., Methods: Thirty-nine patients underwent immediate bilateral SMDP breast reconstructions. Mean time of follow-up was 20 months. SMDP was indicated to reconstruct inferior breast defects in patients with enough remaining breast tissue. Reconstructed (RB) and opposite (OB) breast complications were evaluated and information on esthetic result and patient satisfaction was collected., Results: Tumors (51.2%) measured 2 cm or less (T1) and 66.6% were located in the lower outer quadrants. Mean change in nipple position was 12.5 cm. Immediate RB complications occurred in 8 patients (20.5%), with skin necrosis in 3 (7.6%), infection in 2 (5.1%), dehiscence in 2 (5.1%), and partial areola necrosis in 1 (2.5%) patient. Late complications were observed in 7.6%. All late complications were observed after adjuvant radiotherapy. The cosmetic result was considered to be good or very good in 84.6%, and the majority of patients were either very satisfied or satisfied. All complications were treated by conservative approach., Conclusion: SMDP is a reliable technique and should be given primary consideration in cases of lower quadrant reconstruction. The success of the procedure depends on patient selection, coordinated planning, and careful intraoperative management.

Background: Although transaxillary breast augmentation (TBA) is a well-studied procedure, few previous reports exist concerning the subfascial technique, especially without endoscopic assistance. This study aimed to analyze the feasibility of the technique after breast augmentation in terms of its indication, surgical technique, limitations, and clinical outcome., Methods: For this study, 42 patients underwent TBA without endoscopic assistance. The technique was indicated for patients with breasts of small or moderate volume without ptosis, patients who wanted no breast scars, and patients who had a poorly defined inframammary fold. The mean follow-up period was 16 months. Implant and incision approach complications were evaluated. Information on patient satisfaction was collected., Results: A total of 14 complications occurred in 42 patients, all of them minor. Axillary incision-related complications occurred in 26% of the patients, as represented by a late axillary subcutaneous band (119%), sensory loss in the inner aspect of the arm (71%), and a hypertrophic scar and small wound dehiscence (71%). No patient presented with capsular contracture, visible rippling, or infection. Most of the patients (93%) were either very satisfied or satisfied with their result, and none regretted the surgery., Conclusion: The TBA procedure without endoscopic assistance is a simple and reliable technique for breast augmentation. Most of the complications in this study were minor and predictable. They did not interfere with the aesthetic outcome nor the normal postoperative recovery. With TBA, success depends on patient selection as well as careful intra- and postoperative management.

Background: Although the lateral thoracodorsal fasciocutaneous flap is a well-studied procedure for late breast reconstruction following radical surgery, there are few previous reports regarding its indication, flap design, and clinical outcome following conservative breast surgery., Methods: Thirty-four patients underwent immediate unilateral lateral thoracodorsal fasciocutaneous flap breast reconstructions. Mean time of follow-up was 23 months. The lateral thoracodorsal fasciocutaneous flap was indicated to reconstruct moderate lateral breast defects where there was not enough breast tissue to perform the reconstruction. Flap and donor-site complications were evaluated. Information on aesthetic results and patient satisfaction was collected., Results: All tumors were located in lateral breast regions, and 64.7 percent measured 2 cm or less (T1). Flap complications occurred in four patients (11.8 percent), with partial flap necrosis in three (8.8 percent). Donor-site complications occurred in eight (23.5 percent), with seroma in five (14.7 percent) and wound dehiscence in three (8.8 percent). The cosmetic result was considered to be good or very good in 88.2 percent, and the majority of patients were either very satisfied or satisfied. Surgical intervention was necessary in two cases of wound dehiscence. Serial dorsal puncture in cases of seroma were performed with satisfactory results., Conclusions: The lateral thoracodorsal fasciocutaneous flap is a simple and reliable technique for conservative breast surgery reconstruction. Success depends on patient selection, coordinated planning with the oncologic surgeon, and careful intraoperative management.
