RESUMEN
BACKGROUND: The changes in the pattern of lymphatic drainage of the superficial abdominal wall after abdominoplasty are still unknown. These changes may increase the risk of numerous complications, including seroma formation. Depending on the alterations, the manual lymphatic drainage technique should be modified in postoperative patients. The aim of this study was to map the pattern of lymphatic drainage of the superficial infraumbilical abdominal wall after abdominoplasty. METHODS: Twenty women with indications for abdominoplasty were selected in the Plastic Surgery Division of the Federal University of São Paulo. Intradermal lymphoscintigraphy with dextran 500-99m-technetium was performed in 20 female patients in the preoperative phase and 1 and 6 months after abdominoplasty to evaluate superficial lymphatic drainage of the abdominal wall. RESULTS: Before surgery, all patients presented with abdominal lymphatic drainage toward the inguinal lymph nodes. One and 6 months after abdominoplasty, only 15 percent exhibited the same drainage pathway. Drainage toward the axillary lymph node chain occurred in 65 percent of the patients, 10 percent displayed a drainage pathway toward both the axillary and inguinal lymph nodes, and lymphatic drainage was indeterminate in 10 percent of the cases. CONCLUSIONS: A significant change in lymphatic drainage pathway occurred in the infraumbilical region after abdominoplasty. The axillary drainage path was predominant after the operation, in contrast to the inguinal path observed in the preoperative period. However, 35 percent of cases exhibited alternative drainage. No significant changes were documented between 1 and 6 months postoperatively. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

The aim of this study was the influence of local infiltrating analgesia with levobupivacaine on acute postoperative pain in patients that underwent abdominoplasty in day surgery. Local infiltration anesthesia is an injection of local anesthetic solution in painful areas. General anesthesia and tumescent fluid solution were performed in all patients. The study included 55 patients within age range from 20 to 72 years old. Study was conducted from January 2016 to February 2019.Postoperative pain after abdominoplasty was evaluated. LIA were performed before closure of abdominal wall after resection of skin and subcutaneous fat in lower part of abdominal wall. Infiltration was performed after plication of rectus abdominis muscles with single shot of 40 ml 0.25% Bupivacaine. Postoperative pain was reduced in the abdominal wall and in the wound area around umbilicus and in lower abdomen scar after waking from general anesthesia. Occurrence of acute postoperative was noticed in all participants. 85% of patients required an additional dose of analgesics and only in 3% of patients was required during the first postoperative day discharged during 48 hours. The research has shown that the appearance of acute postoperative pain did not lead to prolonged stay in the facility for day surgery.

Introdução: Abdominoplastia consiste em um dos procedimentos estéticos mais populares realizados no Brasil. Pacientes pósbariátricos representam um desafio peculiar ao cirurgião plástico, uma vez que não só requerem reconstruções complexas, mas também apresentam comorbidades residuais e deficiências nutricionais. O tromboembolismo venoso (TEV) constitui uma complicação grave e potencialmente fatal da abdominoplastia. Apesar da pequena frequência desta complicação, os métodos aceitos como padrões para prevenção de TEV em pacientes após abdominoplastia, incluindo quimioprofilaxia, permanecem controversos. Objetivo: Avaliar a experiência do autor com rivaroxabana para profilaxia de TEV em pacientes submetidos a abdominoplastia após grande perda ponderal. Métodos: Uma série de 396 casos foi conduzida retrospectivamente. Todos os pacientes submetidos à abdominoplastia após cirurgia bariátrica que receberam rivaroxabana foram incluídos. A dose profilática foi de 10mg por dia. Dados demográficos, comorbidades, tipo de cirurgia e complicações foram registrados. Resultados: 396 casos de pacientes pós-bariátricos (356 mulheres e 40 homens) foram submetidos à abdominoplastia e receberam rivaroxabana no pós-operatório, de julho de 2015 a julho de 2018. A média de idade dos pacientes foi de 39,1 anos. O índice de massa corporal médio no momento da abdominoplastia foi de 27,2kg/m². Houve apenas um caso de tromboembolismo venoso (0,25%). Treze pacientes apresentaram hematoma com necessidade de drenagem. Conclusões: A quimioprofilaxia de rotina com rivaroxabana para pacientes submetidos à abdominoplastia após grande perda ponderal revela uma baixa incidência de TEV. Esta medicação oral é bem tolerada e apresenta um perfil de complicação aceitável.
Introduction: Abdominoplasty is one of the most popular aesthetic procedures performed in Brazil. Postbariatric patients present a challenge to the plastic surgeon as not only do they have complex reconstructive challenges but also they have residual medical comorbidities and nutritional deficiencies. A serious and potentially fatal complication of abdominoplasty is venous thromboembolism (VTE). Despite the frequency of this serious complication, the accepted standard methods to prevent VTE in abdominoplasty patients, including chemoprophylaxis, remain controversy. Objective: To evaluate the author experience with rivaroxaban, for VTE prophylaxis in abdominoplasty patients after massive weight loss. Methods: A retrospective 396 cases series were conducted. All patients who underwent abdominoplasty after bariatric surgery and received rivaroxaban were included. The prophylactic dose was 10 mg daily for 30 days, beginning 24 hours postoperatively. Patient demographics, comorbidities, type of surgery and complications were recorded. Results: From July 2015 until July 2018, 396 post bariatric patients (356 women and 40 men) underwent abdominoplasty and received rivaroxaban postoperatively. The mean body mass index prior to their weight loss procedure was 43.8kg/m2 (range, 37.3- 61.9kg/m2) and mean BMI was 27.2kg/m² at the time of the abdominoplasty. Mean patient age was 39.1 years. Only one patient had a symptomatic PTE event. Thirteen patients had a hematoma requiring operative evacuation, and all went on to heal without sequel. Conclusions: Routine chemoprophylaxis with rivaroxaban for abdominoplasty patients after massive weight loss has a low rate of VTE events. This oral medication is well tolerated and has an acceptable complication profile.

BACKGROUND: Photobiomodulation is widely studied for its potential benefits in the wound healing process. Numerous scientific studies have highlighted its effect on various phases of wound repair, but clinical validations are few. This comparative trial aims to evaluate the influence of photobiomodulation on the post-abdominoplasty healing process. METHODS: Seventeen Caucasian women (aged 18-55) who underwent an abdominoplasty were enrolled in this double-blinded, controlled clinical trial. The postoperative scars were divided into two areas; the right side of the scars was treated with ten sessions of photobiomodulation (consisting in three types of wavelengths). The other part of the scars was used as control and did not receive any additional treatment. Clinical assessments of both parts of the scars were scheduled at 1, 6 and 12 months postoperative. RESULTS: Within six months following surgery, significantly improved quality of the scars on the treated side compared with the untreated side was reported by patients and experienced professionals according to Vancouver Scar Scale, Patient and Observer Scar Assessment Scale (p < 0.05) and standardized photographs (p < 0.05). At 1 year of follow-up, patients observed no differences between the treated and untreated sides of the scars. This suggests that photobiomodulation appears to play an early role in the wound healing process, accelerating the first stages of cicatrization. CONCLUSION: This study statistically validates the positive impact of photobiomodulation treatment on the first stages of the postoperative healing process. Carried out on Caucasians participants only, this study should, however, be performed on a more heterogeneous population to definitively confirm these effects on an international population.

Introdução: A lipoaspiração é o sendo segundo procedimento mais realizado no Brasil. Com os avanços da técnica, melhores equipamentos e aumento da segurança no ambiente cirúrgico, passaram-se a ser lipoaspiradas grandes áreas. Contudo, existe uma preocupação com a segurança do paciente. Comitês de segurança têm feito recomendações sobre a infiltração, anestesia, seleção do paciente, volume aspirado, entre outros. A Sociedade Brasileira de Cirurgia Plástica e o Conselho Federal de Medicina também determinaram parâmetros de volumes de segurança do aspirado e superfície corporal aspirada. Ainda assim, a literatura de apoio para as recomendações é escassa. O objetivo é avaliar as alterações dos níveis de hemoglobina, ferro sérico e proteínas totais no pré e pós-operatório mediato (7-10 dias), assim como seus reflexos nos pacientes. Métodos: Realizamos um estudo prospectivo, com pacientes submetidos à lipoaspiração isolada e associada à dermolipectomia abdominal, por indicações estéticas. Avaliamos 30 pacientes, sendo coletados dados demográficos, peso, Índice de Massa Corporal, níveis de hemoglobina, ferro sérico e proteínas totais, no pré-operatório, e entre 7 a 10 dias de pós-operatório. Resultados: A queda da hemoglobina foi entre 2-6g/dl, com média de 3,1g/dl aos 7-10 dia de PO. Tivemos como valor mínimo de hemoglobina 7,8g/dl no pós-operatório com 7-10 dias, enquanto o ferro sérico apresentou redução média de 44,87g/dl. Conclusão: A redução no nível da hemoblogina foi responsável pela sintomatolgia clinica apresentada. A reposição de ferro se mostrou necessária no pós-operatório imediato.
Introduction: Liposuction is the second commonest procedure performed in Brazil. The scope for liposuction has broadened with advances in the technique, with better equipment, and increased safety in the surgical environment. However, there are concerns about patient safety. Safety committees have made recommendations on various aspects of the procedure including infiltration, anesthesia, patient selection, and aspirated volume. The Brazilian Society of Plastic Surgery and the Federal Council of Medicine have also determined the parameters for aspiration safety volumes, and for the aspiration of body surface. However, supporting literature for the recommendations is scarce. The objective is to evaluate changes in hemoglobin, serum iron, and total protein levels in the peri-operative days (between 7 and 10 days), in addition to its impact in patients. Methods: We performed a prospective study, with patients submitted to either liposuction alone, or in conjunction with abdominal dermolipectomy for esthetic indications. We evaluated 30 patients, collecting their demographic data, weight, body mass index, hemoglobin, serum iron, and total protein levels in both, the pre-operative period, and between 7 and 10 post-operative days. Results: The fall in hemoglobin levels were between 2 and 6 g /dL, with an average of 3.1 g /dL between 7 and 10 post-operative days . A minimum hemoglobin value of 7.8 g/dL was noted between 7 and 10 days after surgery, while the mean reduction of serum iron was found to be 44.87 g/dL. Conclusion: The reduction in hemoglobin levels was responsible for the clinical symptoms. Iron supplementation was required in the immediate post-operative period.

BACKGROUND: Anaemia and iron deficiency are common after post-bariatric abdominoplasty, which can involve removal of large areas of skin with associated blood loss. Because the oral absorbability of iron is reduced after bariatric surgery (through reduced intake, reduction of gastric acid secretion for conjugation of iron, and separation of the iron-absorptive areas of the duodenum and jejunum), it has been hypothesised that postoperative intravenous iron supplementation might be used to treat anaemia and iron deficiency in patients submitted to post-bariatric plastic surgeries. We aimed to assess whether intravenous iron administered postoperatively in post-bariatric abdominoplasty could result in increased blood haemoglobin concentrations compared with oral iron supplementation. METHODS: In this open-label, randomised, superiority trial, we recruited women aged 18-55 years undergoing post-bariatric abdominoplasty at two public tertiary referral hospitals in São Paulo, Brazil. Eligible women had been treated for previous obesity with bariatric surgery using the vertical banded gastroplasty technique with Roux-en-Y gastric bypass by laparotomy; had grade III contour deformity via the Pittsburgh rating scale; and had a post-bariatric body-mass index (BMI) lower than 32 kg/m2, with stabilised weight loss for at least 6 months. Women were randomly assigned (1:1) to receive postoperative iron supplementation with two intravenous infusions of 200 mg of iron sucrose (intravenous group) or 100 mg of iron polymaltose complex orally twice a day for 8 weeks (oral group). The primary outcome in both groups was blood haemoglobin concentration at postoperative day 56 after abdominoplasty, with a minimum clinically relevant difference of 1·5 g/dL. Analyses were performed on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT01857011, and the Brazilian Clinical Trials Registry, number RBR-2JGRKQ. The trial is completed. FINDINGS: From April 7, 2014, to June 27, 2016, 102 post-bariatric patients were assessed for eligibility. 56 patients were eligible and were randomly assigned, with 28 allocated to each group. Mean baseline haemoglobin concentration was slightly higher in the oral group than in the intravenous group (12·71 g/dL [SD 1·06] vs 12·24 g/L [1·09]), and by post-operative day 56 was 12·54 g/dL (SD 1·18) and 12·80 g/dL (0·81), respectively (mean difference of 0·26 g/dL, 95% CI -0·28 to 0·80; p=0·009 in favour of the intravenous group). The minimum clinically relevant difference in concentrations was not reached. No adverse events were recorded in the intravenous group, whereas in the oral group, constipation was recorded in five (18%) patients, diarrhoea in three (11%), and nausea in one (4%) patient. INTERPRETATION: Postoperative intravenous administration of iron increased haemoglobin concentrations at 56 days post-operatively and reduced iron deficiency, without adverse events. Although superiority of intravenous iron was not shown, intravenous administration might be useful in post-bariatric patients, especially in those who have body-contouring treatment involving a second surgery within a short period of time. Larger trials, and trials using higher intravenous doses of iron, are needed to further assess the potential efficacy and safety of intravenous iron administration after post-bariatric plastic surgery.

BACKGROUND: After abdominoplasty, patients experience decreased ventilatory function and increased intra-abdominal pressure (IAP). Breathing exercises are used during the pre- and postoperative periods of several abdominal surgeries to prevent or minimize postoperative complications. OBJECTIVES: The aim of this study was to assess the effect of preoperative respiratory physiotherapy on the outcome of abdominoplasty patients. METHODS: Thirty-three patients were divided into 2 groups. The control group (n = 18) received no preoperative intervention. The intervention group (n = 15) performed breathing exercises during the preoperative period, including incentive spirometry, diaphragmatic breathing, shortened expiration, and sustained maximal inspiration. Respiratory physiotherapy started one week before surgery. Breathing exercises were performed daily. They were performed 3 times weekly in the presence of a physiotherapist and patients were instructed to carry on the exercises at home on days without physiotherapy sessions for three sets of 20 repetitions each. Patients were assessed by spirometry and IAP measurements. RESULTS: No significant difference in spirometry was found between groups. However, patients in the intervention group had lower IAP at the start of surgery and at all time points (P = 0.010) compared with controls. CONCLUSIONS: Preoperative respiratory physiotherapy had no impact on spirometry, but may have contributed to reduce IAP intraoperatively.

BACKGROUND: Anaemia and iron deficiency are common complications following post-bariatric abdominoplasty. Given the low oral absorbability of iron resulting from bariatric surgery, it has been hypothesised that postoperative intravenously administered iron supplementation could be used to treat anaemia and to prevent the development of iron deficiency in these patients. METHODS/DESIGN: In this multicentre open-label randomised clinical trial, 56 adult women undergoing post-bariatric anchor-line abdominoplasty will be allocated at a ratio of 1:1 for postoperative supplementation with two intravenously administered applications of 200 mg of iron saccharate or postoperative supplementation with 100 mg of iron polymaltose complex administered orally, twice a day for 8 weeks. The primary outcome is the difference in mean haemoglobin levels between the two groups at eight postoperative weeks. Secondary outcomes evaluated at one, four and eight postoperative weeks include iron profile, reticulocyte count, overall quality of life measured using the Short-Form 36 Health Survey (SF-36) questionnaire, fatigue measured using the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), adverse effects and postoperative complications. DISCUSSION: This randomised clinical trial aims to evaluate the haematopoietic effectiveness of intravenously administered iron supplementation in patients undergoing post-bariatric abdominoplasty. A more effective recovery of haemoglobin levels could help improve the patients' quality of life and could provide an improved haematological status in preparation for the subsequent and frequent plastic surgeries these patients undergo.

BACKGROUND: As more patients undergo bariatric surgery to assist with weight loss, the demand for post-bariatric body contouring surgery, to address both functional and aesthetic concerns, is increasing. However, high wound healing complication rates remain a significant problem for these patients. One theory is that chronic malnourishment and hypoproteinemia may contribute significantly to these wound healing complications. OBJECTIVE: The purpose of this study was to determine the effect of pretreatment protein nutritional supplementation on wound healing in post-bariatric surgery massive weight loss patients undergoing abdominoplasty. Our hypothesis was that protein supplementation would decrease wound healing complications. METHODS: A retrospective review was performed of 23 post-bariatric surgery patients undergoing abdominoplasty who received pretreatment protein nutritional supplementation. This group was compared with a historical control group of 23 post-bariatric surgery patients who underwent abdominoplasty in the period immediately before the implementation of the protein supplementation protocol. Patient demographics and procedural characteristics were similar for the two groups. RESULTS: Forty-six patients were identified who had undergone abdominoplasty, half of whom were prescribed the protein supplementation protocol. Overall wound healing complication rates were significantly lower in the protein-supplemented group (0.0% vs. 21.8%, p = 0.04). There was no significant difference between the protein supplementation and historical control groups in regards to total complication rate. CONCLUSIONS: Pretreatment protein supplementation is a simple intervention that can significantly decrease wound healing complications in post-bariatric surgery massive weight loss patients undergoing abdominoplasty. LEVEL OF EVIDENCE 4: Therapeutic.

UNLABELLED: Body contouring by means of minimally invasive procedures is a growing trend. Current approaches to body contouring often involve a combination of surgical techniques (eg, laser-assisted liposuction) and a series of noninvasive device-based treatments aimed at accelerating recovery and improving aesthetic outcomes. In this case study, we describe a 38-year-old woman who presented with an abdominal-wall mass that resembled a tumor when assessed with magnetic resonance imaging. Twenty-six months before presenting to our office, the patient had undergone laser lipolysis and a series of treatments with a device that delivered dual-wavelength laser energy and vacuum-assisted massage. To address the patient's concerns, we removed the mass and performed abdominal dermolipectomy. No postoperative complications occurred, and the patient was highly satisfied with the aesthetic outcome. The results of histologic studies indicated that the mass was pseudocystic and fluid-filled, surrounded by a fibrous capsule, and characterized as a foreign-body granuloma. Further analysis is warranted regarding the safety of laser lipolysis without aspiration combined with a device delivering dual-wavelength laser energy and vacuum-assisted massage. LEVEL OF EVIDENCE: 5 Risk.

BACKGROUND: Carboxytherapy (CA) refers to the cutaneous and subcutaneous administration of CO(2) for therapeutic purposes. Radiofrequency (RF) is a method that uses electric current for heating layers of the skin. Both techniques are indicated for the treatment of skin laxity. OBJECTIVE: The aim of this study was to compare the effects of CA and RF on human skin. METHODS: After eight patients underwent abdominoplasty, each of them received a single treatment of CA and a single treatment of RF on the right and left infra-umbilical regions, respectively. In the infra-umbilical region, CA was performed on the right and RF was performed on the left side. Untreated skin was used as a control. The sample collection period lasted 120 days. CA was administered at a velocity of 40 mL/min, and the total quantity of CO(2) infused was approximately 20 mL. RF was carried out at a temperature higher than 40°C on the epidermis for 5 min. RESULTS: CA and RF led to collagen remodeling; however, this result was more evident and lasted longer with RF. With CA an increase in elastic fibers was observed, whereas with RF no alteration was observed. CONCLUSION: Our results suggest that RF is more efficient than CA in stimulating collagen synthesis.

A 72-year-old woman became profoundly hypotensive and hypothermic 10 hours after undergoing a panniculectomy. She remained critically ill despite aggressive intensive care, and a diagnosis was not identified despite multiple consultations, imaging, and exploratory laparatomy. No improvement was seen until a large dose of intravenous thiamine alone was administered, dramatically restoring a normotensive and normothermic state. Although few cases of thiamine deficiency have been described in the context of plastic and reconstructive surgery, this case emphasizes the importance of considering this potentially fatal condition, which often does not manifest classically in the early postoperative period.

Herbal medicine is a multibillion-pound industry, and surveys suggest that ~10% of the UK population uses herbal supplements concurrently with prescription medications. Patients and health care practitioners are often unaware of the adverse side effects of herbal medicines. In addition, because many of these herbal supplements are available over the counter, many patients do not disclose these when listing medications to health care providers. A 39-year-old nurse underwent an abdominoplasty with rectus sheath plication after weight loss surgery. Postoperatively, she experienced persistent drain output, and after discharge, a seroma developed requiring repeated drainage in the clinic. After scar revision 10 months later, the woman bled postoperatively, requiring suturing. Again, a seroma developed, requiring repeated drainage. It was discovered that the patient had been taking a herbal menopause supplement containing ingredients known to have anticoagulant effects. Complementary medicine is rarely taught in UK medical schools and generally not practiced in UK hospitals. Many supplements are known to have anticoagulant, cardiovascular, and sedative effects. Worryingly, questions about herbal medicines are not routinely asked in clinics, and patients do not often volunteer such information. With the number and awareness of complementary medications increasing, their usage among the population is likely to increase. The authors recommend specific questioning about the use of complementary medications and consideration of ceasing such medications before surgery.
