Use of negative pressure therapy in closed surgical incisions of post-bariatric dermolipectomy / Uso da terapia de pressão negativa em incisões cirúrgicas fechadas de dermolipectomia pós-bariátrica

Introduction: Negative pressure therapy gains ground in surgical practice as an intervention to improve healing. Post-bariatric patients undergoing abdominal dermolipectomy are at increased risk of local complications. There is a notable dearth of current Brazilian studies on this. This study aims to analyze the presence of complications in patients undergoing post-bariatric dermolipectomy surgery with negative pressure dressing in closed surgical incisions. Method: Descriptive study that evaluated complications of surgical incisions in 20 patients undergoing post-bariatric dermolipectomy surgery with negative pressure therapy. Data tabulated in Windows Excel software and analyzed in the Statistical Package for the Social Sciences 18.0 program. Qualitative variables were presented in simple frequency and quantitative as mean, standard deviation, and amplitude. CEP-UNISUL approved the study. Results: 20 patients undergoing negative pressure therapy, 80% (n=16) female, mean age 39.55 years (±9.08). Anchor incision was chosen in 70% (n=14) of the surgeries, with an average tissue removal of 1940 grams (±710.37) and hospitalization time of 40.20 hours (±19.18), corresponding to 1,66 daily. Only 15% (n=3) of patients had complications (dehiscence, seroma, and hematoma, which occurred in the same proportion). There was no case of necrosis. Conclusion: The use of negative pressure therapy in closed surgical incisions of post-bariatric dermolipectomy seems to contribute to reducing postoperative complications.

Introdução: Terapia de pressão negativa ganha espaço na prática cirúrgica como intervenção para melhorar cicatrização. Pacientes pós-bariátricos submetidos a dermolipectomia abdominal apresentam maior risco de complicações locais. Há uma notável escassez de estudos brasileiros atuais acerca disso. O objetivo desse estudo é analisar a presença de complicações em pacientes submetidos a cirurgia de dermolipectomia pós-bariátrica com curativo de pressão negativa em incisões cirúrgicas fechadas. Método: Estudo descritivo que avaliou complicações de incisões cirúrgicas de 20 pacientes submetidos a cirurgia de dermolipectomia pós-bariátrica com terapia de pressão negativa. Dados tabulados no software Windows Excel e analisados no programa Statistical Package for the Social Sciences 18.0. Variáveis qualitativas foram apresentadas em frequência simples e quantitativas através de média, desvio padrão e amplitude. O estudo foi aprovado pelo CEP-UNISUL. Resultados: 20 pacientes submetidos a terapia de pressão negativa, sendo 80% (n=16) do sexo feminino, com idade média de 39,55 anos (±9,08). Incisão em âncora foi escolha em 70% (n=14) das cirurgias, com retirada média de tecido de 1940 gramas (±710,37) e tempo de hospitalização de 40,20 horas (±19,18), correspondendo a 1,66 diárias. Apenas 15% (n=3) dos pacientes apresentaram complicações (deiscência, seroma e hematoma, que aconteceram na mesma proporção). Não houve caso de necrose. Conclusão: Uso da terapia de pressão negativa em incisões cirúrgicas fechadas de dermolipectomia pós-bariátrica parece contribuir na redução das complicações pós-operatórias.

The main abdominoplasty techniques used in post-bariatric patients after massive weight loss: systematic review / As principais técnicas utilizadas de abdominoplastia em pacientes pós-bariátricos após massiva perda de peso: revisão sistemática

Introduction: Obesity is defined by a body mass index (BMI) ≥30 kg/m2, and today approximately 2.1 billion adults are obese. With this high number of obese people, the demand for treatment via bariatric surgery has been increasing to reduce weight, resolve comorbidities and improve quality of life. However, intense weight loss can cause adverse physical, aesthetic, and psychological effects. Plastic surgery becomes essential to resolve these adverse effects. According to the International Society of Plastic Surgery, 112,116 abdominoplasties were performed in 2020, representing 8.6% of all plastic surgeries performed in Brazil. The objective is to present the main abdominoplasty techniques in postbariatric patients. Method: Studies that met the previously defined inclusion criteria were included. Results: A total of 28 references were included in this systematic review. Discussion: Most seek abdominoplasty due to the excess skin remaining in various body regions and the impact on post-bariatric patients' quality of life and mental health. The surgical techniques addressed are classic abdominoplasty; fleur-de-lis or anchor; circumferences; and Scarpa's fascia. The total number of complications was 42%; the main ones observed were scarring, skin dehiscence, infection, and necrosis; the three added up to 32%. Conclusion: The improvement in the quality of life of patients undergoing abdominoplasty is evident, but further research is needed to relate abdominoplasty techniques to these patients with postoperative complications.

Introdução: A obesidade é definida pelo índice de massa corporal (IMC) ≥30 kg/m2 , e hoje cerca de 2,1 bilhões de adultos são obesos. Com esse alto número de obesos, a procura por tratamento via cirurgia bariátrica vem aumentando com o intuito de redução de peso, resolução de comorbidades e melhora da qualidade de vida. Entretanto, a intensa perda de peso pode ocasionar efeitos adversos físicos, estéticos e psicológicos. A cirurgia plástica passa a ser fundamental para resolução desses efeitos adversos. Segundo a Sociedade Internacional de Cirurgia Plástica, foram realizados 112.116 abdominoplastias em 2020, representando 8,6% de todas as cirurgias plásticas realizadas no Brasil. O objetivo é apresentar as principais técnicas de abdominoplastia em pacientes pós-bariátricos. Método: Foram incluídos estudos que cumprissem os critérios de inclusão previamente definidos. Resultados: Foi incluído nesta revisão sistemática um total de 28 referências. Discussão: Devido ao excesso de pele remanescente em várias regiões do corpo e o impacto na qualidade de vida e saúde mental dos pacientes pós-bariátricos, a maioria procura por abdominoplastia. As técnicas cirúrgicas abordadas são abdominoplastia clássica; flor-de-lis ou âncora; circunferências; e fáscia de Scarpa. O total de complicações foi de 42%, as principais observadas foram de cicatrização; deiscência de pele, infecção e necrose; as três somaram 32%. Conclusão: A melhora na qualidade de vida dos pacientes submetidos a abdominoplastia é evidente, porém é necessária a realização de mais pesquisas que relacionem as técnicas de abdominoplastia nesses pacientes com suas complicações pós-operatórias.

A comparative study of the clinical application of anatomical healing abutments versus finished healing abutments for mandibular first molar implants / 口腔疾病防治

Objective @#To evaluate the effect of anatomical healing abutments for mandibular first molars on the morphological changes of gingival soft tissue after implant restoration, as well as on peri-implant gingival molding, food ingrowth and patient satisfaction, to provide a basis for clinical selection. @*Methods @# Twenty-six patients who received implant restoration for a single missing mandibular first molar between September 2020 and September 2021 at the Oral Implant Center of Changsha Stomatological Hospital were randomly divided into a control group (13 cases with 14 implants) and a trial group (13 cases with 14 implants), of which 12 were male and 14 were female; the trial group had anatomical healing abutments applied for 4 weeks and then underwent crown restoration, while the control group finished five time points (before the second stage surgery, 4 weeks after the second stage surgery, immediately after the crown restoration, 4 weeks after the crown restoration, and 12 weeks after the crown restoration). A 3Shape intraoral scanner was used to scan the jaw before and 4 weeks after the second stage surgery to quantify the soft tissue changes and compare the effect of the healing abutment on gingival molding between the two groups. The incidence of food impaction was recorded and compared between the two groups at 4 weeks and 12 weeks after crown restoration. Patient satisfaction was recorded and compared between the two groups immediately after crown restoration, 4 weeks after crown restoration and 12 weeks after crown restoration@*Results @# Four weeks after implant surgery, it was observed that the gingival proximal and distal gingival papillae increased on the coronal side in the test group compared to the control group, 0.50 (0.26, 0.72) mm in the near-medium test group and 0.27 (0.24, 0.38) mm in the control group, with a statistically significant difference (P = 0.029), and 0.48 (0.26, 0.62) mm in the far-medium test group and 0.23 (0.13, 0.39) mm in the control group, with a statistically significant difference (P = 0.004). There was no statistically significant difference (P>0.05) in the buccolingual to gingival margin apex to coronal molding or in the buccolingual to lingual soft tissue at 0, 1, or 2 mm of the root of the middle 1/3 apex of the buccal and lingual gingival margins between the two groups. Compared to the control group, there was no statistically significant difference in the incidence of food impaction observed 4 weeks and 12 weeks after crown restoration in the test group (P>0.05). The satisfaction scores were higher in the trial group than in the control group immediately, 4 weeks, and 12 weeks after crown restoration, and the difference between the groups was statistically significant (P < 0.05). @*Conclusion @# The anatomical healing abutment for the implant mandibular first molar was superior to the finished healing abutment in terms of soft tissue contouring with an increase in the coronal aspect of the proximal and distal gingival papillae, resulting in high patient satisfaction.

Facial contouring surgery combined with the clinical application of minimally invasive tunnel separation and lifting technique / 中华医学美学美容杂志

Objective:To explore a simple and effective clinical method for improving facial sagging while performing maxillofacial contouring surgery.Methods:From October 2020 to October 2021, 50 patients with mandibular angle and malar surgery in the Plastic Surgery Department of Sichuan Friendship Hospital were selected, aged 30-43 years, with the average age of 37 years, including 44 females and 6 males. Maxillofacial contouring surgery was performed under transnasal intubation general anesthesia, the interorgual jaw groove incision was performed with a swing saw for bilateral long arc osteotomy, and the maxillary gingival groove incision and sideburn skin incision were performed for zygomatic osteotomy reduction and zygomatic arch incision. A small incision about 3 mm long was taken 1 cm from the edge of the temporal hair; a special conical cannula stripper was used to perform subcutaneous tunnel peeling to the zygomatic fat pad and masseter muscle ligament, anterior appendage ligament, then a two-way barb line was placed through the casing to lift vertically upwards, pierce above the posterior papillae of the ear, and the excess thread was cut off.Results:Following-up for 3-12 months, all recipients recovered well after surgery, the skin of the middle and lower parts of the postoperative body was lifted to varying degrees, the cheek fat pad was lifted, the jaw contour line was clearer, and the nasolabial fold was significantly improved as compared with that before the operation.Conclusions:At the same time as facial contouring surgery, the use of minimally invasive tunnel separation and lifting technique can effectively improve the skin sagging in the middle and lower parts, and it is simple and effective, and the clinical application effect is good.

Prevalência de cirurgia de contorno corporal em pacientes pós-bariátricos em um hospital universitário / Prevalence of body contouring surgery in post-bariatric patients at a university hospital

Introdução: O número crescente de pacientes com perda ponderal maciça, após cirurgias bariátricas, correlaciona-se com a procura por cirurgias de contorno corporal. Tais procedimentos reduzem queixas físicas e psicológicas, influenciando positivamente a qualidade de vida dessas pessoas. Todavia, há poucos dados quanto à resposta dos serviços que oferecem tratamento cirúrgico para obesidade mórbida frente a essa necessidade. O estudo tem como objetivo aferir a prevalência de cirurgia do contorno corporal entre 2015 e 2018, em pacientes previamente submetidos à cirurgia bariátrica, nos anos de 2014 e 2015, em um hospital universitário. Métodos: Consulta ao sistema de informação hospitalar e a prontuários médicos a fim de aferir prevalência institucional de cirurgia de contorno corporal pós-bariátrica. Foram excluídos pacientes que não tenham sido submetidos a ambas as cirurgias em nosso Serviço, os que realizaram os referidos procedimentos cirúrgicos em outros anos, bem como aqueles com registros incompletos. Resultados: Foram realizadas cirurgias bariátricas em 208 pacientes. Desses, 11% (n=23) foram submetidos a 27 cirurgias do contorno corporal, sendo a dermolipectomia abdominal (n=16) a mais realizada. A realização de mais de um procedimento para correção de deformidade corporal ocorreu em 13% (n=3) dos pacientes. A média de idade dos pacientes submetidos a cirurgia do contorno corporal foi de 37 anos, a maioria do sexo feminino (96%, n=22). Conclusão: A cirurgia do contorno corporal constitui etapa importante do tratamento da obesidade mórbida e tem caráter reparador. Há imensa carência dessa terapêutica, o que compromete irremediavelmente os resultados obtidos pela cirurgia bariátrica.

Introduction: The growing number of patients with massive weight loss after bariatric surgery is correlated with the demand for body contouring surgery. Such procedures reduce physical and psychological complaints, positively influencing the quality of life of these people. However, there is little data on the response of services that offer surgical treatment for morbid obesity to this need. The study aims to measure the prevalence of body contouring surgery between 2015 and 2018, in patients previously underwent on a bariatric surgery, in 2014 and 2015, at a University Hospital. Methods: Research in the hospital information system and medical records in order to assess the institutional prevalence of post-bariatric body contouring surgery. Patients who did not undergo both surgeries in our Service, those who underwent these surgical procedures in other years, as well as those with incomplete medical records were excluded. Results: Bariatric surgeries were performed in 208 patients. Of these, 11% (n=23) underwent 27 body contouring surgeries, with abdominal dermolipectomy (n=16) being the most frequently performed. The performance of more than one procedure to correct body deformity occurred in 13% (n=3) of patients. The mean age of patients undergoing body contouring surgery was 37 years, the majority was female (96%, n=22). Conclusion: Body contouring surgery is an important step in the treatment of morbid obesity and has a restorative feature. There is a huge lack of this therapy, which irreparably compromises the results obtained by bariatric surgery.

An Assessment of 3.5mm Reconstruction Plate Fixation in Olecranon Fractures

Background: Olecranon process is a large, curved eminence comprising of the proximal and posterior part of the ulna. It lies subcutaneously which makes it more vulnerable to injury. Due to intra-articular extension of fractures, anatomical reduction and early mobilization should be achieved in every case and usually managed surgically. Aims and Objectives: To access the results of reconstruction plate in fracture olecranon.Materials &Methods: This was a prospective study consisted of 25 cases of olecranon fractures which were managed by open reduction and internal fixation using 3.5mm reconstruction plate. Patients were followed up every month till 6 months. At each follow up visit clinical and radiological parameters were assessed: Final assessment was done at 6 months using the Mayo Elbow Performance Score.Result: According to the AO classification, Type A-1 � 7 cases, A-3 � 1case, B-1 � 13 cases, B-3 � 1 case, C-1 � 1 case, C-2 � 1 case, C-3 � 1 case. An adequate reduction was maintained in all fractured olecranon until union. Average radiological union time was 12 weeks in 72% cases, 15 weeks in 16% cases, 18 weeks in 8% cases and > 18 weeks in 4% cases. The results were graded as per the criteria laid by Rogers et al as excellent in 84% cases, good in 12% and unsatisfactory in 4% cases. 2 cases developed superficial infection and 1 deep infection and 1 delayed union.Conclusion: Open reduction and internal fixation of fracture of olecranon with 3.5mm reconstruction plate is based on sound biomechanical principle with a good functional outcome and a low incidence of complications

Post-bariatric body contouring surgery: analysis of complications in 180 consecutive patients / Cirurgia de contorno corporal pós-bariátrica: análise das complicações em 180 pacientes consecutivos

ABSTRACT Introduction: bariatric surgery is the main treatment for cases of severe obesity and body contour surgery to correct body dysmorphia resulting from weight loss. However, these procedures are associated with a significant number of postoperative complications. Objective: this study aims to analyze complications in post-bariatric patients undergoing body contour surgeries and correlating them with the age and BMI of these patients. Methods: the current study is a retrospective study evaluating 180 consecutive patients undergoing body contour surgery after bariatric surgery within a period of three years (2014-2016). Data such as age, gender, Body Mass Index before bariatric and plastic surgeries, type of surgery performed and complications were collected, and correlated the age as well as the BMI of the patients in the pre-bariatric (PB) and pre-plastic (PP) periods with the complications presented. Results: of the 180 patients evaluated, 91.7% were females (n = 165), and the mean age was 46.3 ± 1.7 years. The most performed surgery was abdominoplasty (48.9%), followed by mammaplasty (21.1%). Some complications occurred in 26.1% of the patients with partial dehiscence (40.4%) and seroma (14.9%) being the most frequent. Patients who presented complications had a higher mean age (50.8 years) than those who presented with no complications, and major complications accounted for 2.7% of the sample. Conclusions: a statistically significant number of surgeries progressed without complications and, when they occurred, there were minor complications in most of the sample. Complications were more frequent in older patients with some of them having a BMI over 30 Kg/m2.

RESUMO Introdução: a cirurgia bariátrica é o principal tratamento para os casos de obesidade grave e a cirurgia de contorno corporal trata a dismorfia corporal resultante desta perda de peso. No entanto, estes procedimentos estão associados a um número significativo de complicações pós-operatórias. Objetivo: analisar as complicações maiores e menores que ocorreram nos pacientes pós-bariátricos submetidos a cirurgias reparadoras do contorno corporal e correlacioná-las com idade e IMC destes pacientes. Métodos: estudo retrospectivo que avaliou 180 pacientes consecutivos submetidos a cirurgia de contorno corporal, após cirurgia bariátrica, no período de 3 anos (2014-2016). Foram coletados dados como idade, gênero, IMC pré-bariátrica e pré-plástica, tipo de cirurgia realizada e complicações, correlacionando a idade e o IMC dos pacientes nos períodos pré-bariátrica (PB) e pré-plástica (PP) com as complicações apresentadas. Resultados: dos 180 pacientes avaliados, 91,7% eram do gênero feminino (n=165) e a idade média foi de 46,3 ± 1,7 anos. A cirurgia mais realizada foi abdominoplastia (48,9%), seguida da mamoplastia (21,1%). Complicações ocorreram em 26,1% dos pacientes, sendo deiscência parcial a principal (40,4%) seguida de seroma (14,9%). Pacientes com complicações apresentaram média etária maior (50,8 anos) que os sem complicações, sendo que as complicações maiores ocorreram em 2,7% da amostra. Conclusões: a maioria estatisticamente significante das cirurgias cursou sem complicações e, quando ocorreram, foram complicações menores na maior parte da amostra. As complicações foram mais frequentes nos pacientes de idade mais avançada, dos quais alguns com IMC maior que 30kg/m2.

Comprehensive correction of maxillofacial bone deformity-consideration and combined application of orthognathic surgery and facial contouring surgery / 华西口腔医学杂志

The maxillofacial skeleton is the basis of the contour of the face. Orthognathic surgery and facial contouring surgery change jaw tissue and affect facial appearance in different manners. Orthognathic surgery is the main method to correct dental and maxillofacial deformities. It changes the shape of the jaw and improves the occlusal relationship by changing the three-dimensional position of the jaw. Facial contouring surgery mainly adopts the method of "bone reduction", which changes the "amount"of the jawbone by cutting a part of the bone tissue to improve the facial appearance, generally without changing oral function. The combined use of orthognathic surgery and facial contouring surgery is becoming increasingly common in clinical practice. This also requires oral and maxillofacial surgeons to have a holistic consideration of the comprehensive correction of maxillofacial bone deformity, and to perform comprehensive analysis of jaw deformities and jaw plastic surgery to achieve the most ideal results. The author's team has been engaged in the clinical work of orthognathic surgery and facial contouring surgery and accumulated rich clinical experience in the comprehensive correction of maxillofacial bone deformity. In this article, the indications, treatment goals, treatment modes, treatment methods, and key points in the surgical operations of comprehensive maxillofacial bone surgery were summarized.

Factores que afectan la calidad de vida en pacientes con cirugía de contorno corporal: estudio de cohorte / Factors that have an impact on quality of life in patients with body contouring surgery: a cohort study

Resumen Objetivo: Identificar los factores determinantes de la mejoría de la calidad de vida en pacientes sometidos a cirugía de contorno corporal. Materiales y Método: Se estudió una cohorte prospectiva de 113 pacientes sometidos a cirugía de contorno corporal. Se estudiaron características sociodemográficas, mediciones antropométricas, variables relativas a la cirugía y se aplicó el instrumento Body-Qol®. Para el análisis estadístico se utilizó estadística descriptiva, modelos de ecuaciones de estimación generalizada y modelos de regresión lineal y logística. Resultados: Se encontró mejoría en la calidad de vida de forma global (p < 0,0001) y por dominios. Los pacientes con pérdida masiva de peso tuvieron peores puntajes pre y postoperatorio, sin embargo, un delta de mejoría comparable con los pacientes estéticos. Dentro de los factores determinantes, existió una relación positiva entre la edad y la mejoría en la calidad de vida de forma global. El índice de masa corporal (IMC) se encontró asociado negativamente con la mejoría del puntaje global. Dentro de los factores de la cirugía, los pacientes sometidos a lipoabdominoplastía tuvieron una mayor mejoría con respecto a otras técnicas. Además, el patrón de resección ampliado y en flor de Lis se asoció a menor mejoría en el puntaje global. Conclusión: La cirugía de contorno corporal mejora la calidad de vida de forma significativa. Los principales factores determinantes de esta mejoría fueron la edad, el IMC, el antecedente de pérdida masiva de peso y el patrón de resección.

Aim: To identify the factors that have an impact on the quality of life of patients with body contouring surgery. Materials and Method: A prospective cohort of 113 patients was studied. Sociodemographic characteristics, antropometric measures and variables related to the surgery were analized. The Body-Qol® instrument was aplied. Descriptive statistic, generalized estimated equation models and lineal and logistic regresions were used for the statistical analysis. Results: Improvement in the quality of life was found globally (p < 0,0001) and in every domain of the scale. The patients with massive weight loss had worse scores pre- and post-operatively than the esthetic patients. A positive association between age and improvement on quality of life was found. Body mass index (BMI) was negatively associated with improvement of the score. The patients that had a lipoabdominoplasty had a major improvement in comparison with other techniques. Also, the extended resection pattern and Fleur de Lis pattern were associated with lesser improvement in the global score. Conclusion: Body contouring surgery improves quality of life significantly. The principal factors that have an impact on quality of life were age, BMI, massive weight loss and resection pattern.

A study to evaluate the adequacy of pelvic lymph node coverage in carcinoma cervix patients in Indian population by conventional four field box technique using computerized tomography simulation based pelvic lymph node contouring

Background: Traditionally pelvic External Beam Radiotherapy is delivered with four field box technique in carcinoma cervix patients. The primary aim of this prospective observational study is to determine the adequacy of pelvic lymph nodal coverage by conventional Four Field Box Technique with the help of pelvic lymph node contouring by CT simulation.Methods: Between January 2013 and August 2015 sixty patients with biopsy proven Carcinoma Cervix were enrolled in this study. Of these fifty-three patients were available for final analysis. CT simulation based Pelvic lymph node contouring was done for each patient. Then two External Beam Radiotherapy plans were generated, one contoured based and the other based on bony landmark based Four Field Box Technique. The number of patients whose contoured lymph nodes lies partly outside the field borders of the bony landmark-based plan and also its extent was determined. D90 of various groups of pelvic lymph nodes obtained from both the plans were compared using ‘paired sample t - test’.Results: It was seen that with Four Field Box Technique there is inadequate coverage of common iliac lymph nodes in 34/53 patients. The difference between the mean D90 of common iliac lymph nodes in two sets of plans was found to be statistically significant.Conclusions: Pelvic field planning should be individualized. CT simulation-based radiotherapy planning should be done for each individual patient to adequately cover the nodal microscopic disease.

A Novel Technique for Fixation of Non-union Unicondylar Hoffa’s Fracture: A Case Report

@#Hoffa fractures are rare and difficult fractures to manage. Hoffa fracture involves a coronal plane fracture of posterior femoral condyle. Non-union in Hoffa fracture is further difficult to manage. The surgical management for such nonunion includes open reduction with recon/LCP plate or screw fixation with bone grafting. The problem with plates is the difficulty in contouring the plates according to the shape of posterior femoral condyles. We describe a new technique with 2 L shaped neutralisation plates placed in a circular fashion. This technique provides a more rigid construct and gives better holding strength of screws in Hoffa fragment. This enhances union and mobilisation can be started early.

Recuperação clínica e laboratorial dos pacientes submetidos à cirurgia combinada de lipoaspiração corporal e lipoabdominoplastia / Clinical and laboratory recovery of patients undergoing body liposuction associated with lipoabdominoplasty

Introdução: A lipoaspiração corporal e abdominoplastia são cirurgias muitas vezes realizadas em conjunto para obter melhores resultados na modelagem corporal. Cirurgias associadas sempre aumentam a espoliação, por isto conhecer o comportamento da hemoglobina (Hb) no pós-operatório e a recuperação do paciente submetido a estas cirurgias combinadas é importante para sua segurança. O objetivo deste trabalho foi estudar a queda da Hb e a recuperação clínica e laboratorial dos pacientes submetidos à cirurgia combinada de lipoaspiração corporal e lipoabdominoplastia. Métodos: Realizou-se um estudo prospectivo em pacientes submetidos à lipoaspiração corporal e lipoabdominoplastia, coletando-se hemogramas antes da indução anestésica, ao final da cirurgia, antes da alta hospitalar, após a 1ª, 2ª e 4ª semanas de pós-operatórios e também acompanhando suas evoluções clínicas. Resultados: A média da Hb ao final da cirurgia e na alta hospitalar foi de 10,4g/dl (desvio padrão (DP) 0,76) e 8,92g/dl (DP 0,86), respectivamente. A recuperação em média da Hb após 1ª, 2ª e 4ª semanas foi de 2,4% (DP 18,07), 41,6% (DP 18,4) e 74% (DP 15,2), respectivamente, em relação a redução que ocorreu entre a Hb inicial e a da alta hospitalar. Queixas de fraqueza e lipotimia foram frequentes até o segundo dia. Conclusão: A melhora clínica ocorreu até o segundo dia de pós-operatório (DPO) e a hemoglobina levou aproximadamente 1 mês para normalizar na maioria dos pacientes tratados apenas com reposição oral de ferro, sem necessidade de hemotransfusão.

Introduction: Body liposuction and abdominoplasty are surgeries often performed together to obtain superior results in body modeling. Since associated surgeries often increase spoliation, being aware of the evolution of hemoglobin (Hb) in the postoperative period and during the recovery of the patients undergoing these associated surgeries is important for their safety. This study aimed to analyze the decrease in Hb and the clinical and laboratory results throughout the recovery of patients undergoing body liposuction associated with lipoabdominoplasty. Methods: A prospective study was conducted with patients undergoing body liposuction and lipoabdominoplasty. CBCs were collected before anesthetic induction, at the end of the surgery, before hospital discharge, after the 1st, 2nd, and 4th postoperative weeks, and during their clinical follow-up period. Results: The average Hb values at the end of surgery and hospital discharge were 10.4 g/dL (standard deviation (SD) 0.76) and 8.92 g/dL (SD 0.86), respectively. The average values during the recovery of Hb after the 1st, 2nd, and 4th weeks were 2.4% (SD 18.07), 41.6% (SD 18.4), and 74% (SD 15.2), respectively. This is in relation to the reduction between the initial Hb and at hospital discharge. Complaints of weakness and lipothymia were frequent until the second day. Conclusion: Clinical improvement was observed until the second postoperative day (PO day). Hemoglobin required approximately 1 month to normalize in most patients. These patients were treated only with oral iron replacement and did not require blood transfusions.

Lipoaspiração de definição abdominal / Abdominal etching

Introdução: A lipoaspiração de definição abdominal consiste na criação de sulcos em locais específicos do abdome através da retirada de gordura em toda sua espessura, incluindo a camada superficial, permitindo um maior detalhamento da musculatura. O objetivo deste estudo foi avaliar os resultados da técnica de lipoaspiração na definição abdominal. Métodos: Foram avaliadas 80 pacientes do sexo feminino no período de 2017 a 2018. O grau de definição e as complicações relacionadas ao procedimento foram avaliadas pelo autor. Todas as pacientes responderam um questionário padrão sobre grau de definição abdominal, satisfação, naturalidade do resultado, aumento da atividade física e melhora da alimentação. Resultados: A média de idade das pacientes foi de 38,97 anos e a média de índice de massa corporal, 24,01. Gestação prévia foi observada em 75% dos casos, cirurgia abdominal pregressa em 25% e tabagismo em 2,5%. Cirurgias simultâneas foram realizadas em 90%. Em relação ao tipo de cirurgia realizada, ocorreu a seguinte distribuição: 40% lipoaspiração isolada, 36,25% lipoabdominoplastia, 12,5% minilipoabdominoplastia, 10% lipoaspiração pós-abdominoplastia e 1,25% lipoabdominoplastia reversa. Grau 2 de definição abdominal foi observado em 86,25% e complicações ocorreram em 8 pacientes. O índice de satisfação foi de 91,7% e o resultado foi classificado como natural por 97,5% das pacientes. Conclusão: A lipoaspiração de definição abdominal promoveu um alto índice de satisfação e naturalidade à região abdominal. Esse resultado pode ser atingido através da técnica de lipoaspiração convencional, sem nenhum dispositivo tecnológico adicional. Contudo, são necessários novos estudos para avaliação dos resultados em longo prazo.

Introduction: Abdominal etching involves improvement of the appearance of the abdominal musculature by removing fat from several skin layers, including the superficial layer. This study evaluated the aesthetic results of abdominal etching using liposuction. Methods: The aesthetic results and surgical complications of female patients were evaluated between 2017 and 2018. All study patients answered a standard questionnaire about the extent of improvement in body image, overall satisfaction level, naturalness of the result, and changes in exercise and dietary habits. Results: The mean patient age was 38.97 years, while the mean body mass index was 24.01. In our sample, 75% of the subjects had previous pregnancies, 25% had previous abdominal surgeries, and 2.5% had a history of smoking. Simultaneous surgeries were performed in 90% of cases. The following surgery types were performed: liposuction alone (40.00%), liposuction + abdominoplasty (36.25%), miniabdominoplasty (12.50%), abdominoplasty + liposuction (10.00%), and reverse abdominoplasty (1.25%). Moderate aesthetic improvement was observed in 86.25% of the patients, and surgical complications occurred in eight patients. The satisfaction rate was 91.7%, and the result was classified as natural by 97.5% of the patients. Conclusion: Abdominal etching promoted high patient satisfaction and achieved a natural appearance of the abdomen. This surgical outcome was achieved using conventional liposuction without the need for additional techniques. However, further studies are needed to evaluate long-term outcomes.

Comparação entre as complicações da lipoabdominoplastia sem preservação da fáscia de Scarpa com abdominoplastia clássica: um estudo prospectivo cego / Complications of lipoabdominoplasty without Scarpa fascia preservation versus classic abdominoplasty: a prospective blind study

Introdução: Abdominoplastia é um dos procedimentos cirúrgicos estéticos mais realizados. Seroma é a complicação local mais comum associada com abdominoplastia, com uma incidência média de 10%. A maior incidência de seroma pós-operatório (PO) ocorre no décimo primeiro dia PO. Ecografia abdominal é o método de escolha para o diagnóstico de seroma após abdominoplastia. Novas técnicas surgiram ao longo dos anos na tentativa de trazer melhores resultados estéticos com menos complicações, como lipoabdominoplastia descrita por Saldanha. Porém, estudos anatômicos recentes questionam a necessidade da manutenção da fáscia de Scarpa descrita na técnica de lipoabdominoplastia, descrevendo que em torno de 90% do sistema linfático abdominal está no plano subdérmico e 10% em um sistema linfático profundo justa-aponeurose abdominal. O objetivo é comparar a incidência de seroma na lipoabdominoplastia sem preservação da fáscia de Scarpa com a abdominoplastia clássica. Métodos: Coorte prospectiva, cega na qual serão analisados 40 pacientes consecutivos que realizaram abdominoplastia sem lipoaspiração associada (n = 20) ou lipoabdominoplastia (n = 20) no Hospital de Clínicas de Porto Alegre entre abril de 2016 e maio de 2017. Todos foram submetidos à ecografia de parede abdominal no 10o dia PO. Resultados: A incidência de seroma foi de 5% (n = 1) no grupo de abdominoplastia clássica e de 10% (n = 2) no grupo de lipoabdominoplastia, sem diferença estatística. Conclusão: Estes resultados, neste grupo de pacientes, mostram que não houve diferença estatística entre os dois grupos.

Introduction: Abdominoplasty is among the most commonly performed surgical procedures. Seroma is the most common local complication associated with abdominoplasty, with an average incidence of 10%. The highest incidence of postoperative (PO) seroma occurs on the eleventh postoperative day (POD). Abdominal ultrasound is the method of choice for diagnosing seroma after abdominoplasty. New techniques have emerged aiming to improve aesthetic results with fewer complications, such as lipoabdominoplasty described by Saldanha. However, recent anatomical studies have questioned the need for Scarpa fascia preservation recommended in the lipoabdominoplasty technique, describing that around 90% of the abdominal lymphatic system is in the subdermal plane, while the other 10% is in a deep lymphatic system near the abdominal aponeurosis. The objective is to compare the incidence of seroma in lipoabdominoplasty without Scarpa fascia preservation to that in classic abdominoplasty. Methods: Prospective blinded cohort in which 40 consecutive patients who underwent abdominoplasty without associated liposuction (n = 20) or lipoabdominoplasty (n = 20) at the Hospital de Clínicas of Porto Alegre between April 2016 and May 2017 were analyzed. All patients underwent abdominal wall ultrasonography on the tenth POD. Results: The incidence of seroma was 5% (n = 1) in the classic abdominoplasty group and 10% (n = 2) in the lipoabdominoplasty group, with no statistical difference. Conclusion: These results showed no statistically significant intergroup difference in seroma development.

Automatic segmentation of organs at risk for nasopharyngeal carcinoma with Smart Segmentation and MIM Atlas / 中华放射医学与防护杂志

Objective@#To compare the accuracy of two automatic segmentation softwares (Smart Segmentation and MIM Atlas) in organs at risk (OARs) contouring for nasopharyngeal carcinoma (NPC).@*Methods@#Totally 55 NPC patients were retrospectively reviewed with manually contoured OARs on CT images, in which 30 cases were randomly selected to create a data base in the Smart Segmentation and MIM Atlas. The remaining 25 cases were automatically contoured with Smart Segmentation and MIM as test cases. The automatic contouring accuracies of two softwares were evaluated with Dice coefficient(DSC), Hausdorff distance(HD), and absolute volume difference(△V) using manual contours as a golden standard.@*Results@#The overall DSC, HD and △V of all organs contoured by MIM Atlas and Smart Segmentation were (0.79±0.13) vs. (0.62±0.24) (t=14.06, P<0.05), (5.50±3.84)mm vs.(8.38±4.88)mm (t=-11.40, P<0.05), and (1.52±2.46) cm3 vs. (2.38±3.57) cm3 (t=-4.70, P<0.05), respectively. The average DSC of 11 organs (brain stem, optic chiasm, bilateral lens, bilateral optic nerve, bilateral eyeballs, bilateral parotid gland, spinal cord) delineated by MIM Atlas was statistically greater than that of Smart Segmentation (t=5.27, 4.41, 6.34, 5.70, 10.62, 7.45, 3.96, 4.26, 6.25, 5.42, 7.23, P<0.05). The average HD of 10 organs (brain stem, optic chiasm, bilateral lens, bilateral optic nerve, bilateral eyeballs, left parotid gland, spinal cord) delineated by MIM Atlas was statistically less than that of Smart Segmentation (t=-4.51, -4.49, -3.92, -3.45, -5.36, -5.56, -3.89, -3.90, -3.60, -3.68, P<0.05). The average △V of 6 organs (brain stem, optic chiasm, left len, bilateral optic nerve, right eyeball) delineated by MIM Atlas was statistically less than that of Smart Segmentation (t=-2.83, -3.39, -2.56, -2.27, -2.43, -2.51, P<0.05).@*Conclusions@#Both softwares have reasonable contouring accuracy for larger organs. The accuracy decreased with the decrease of organ volumes and blurred boundary. Generally, MIM Atlas′s performs better than Smart Segmentation does.
