Risk factors for the development of surgical site infection in bariatric surgery: an integrative review of literature / Fatores de risco para o desenvolvimento de infecção de sítio cirúrgico em cirurgia bariátrica: revisão integrativa / Factores de riesgo para el desarrollo de infección del sitio quirúrgico en cirugía bariátrica: una revisión integradora

Abstract Objective: to evaluate evidence on risk factors for the development of surgical site infection in bariatric surgery. Method: integrative review. The search for primary studies was performed in four databases. The sample consisted of 11 surveys. The methodological quality of the included studies was assessed using tools proposed by the Joanna Briggs Institute. Data analysis and synthesis were performed in a descriptive manner. Results: surgical site infection rates ranged from 0.4% to 7.6%, considering the results of primary studies, in which patients underwent laparoscopic surgery. In surveys of participants undergoing surgical procedures with different approaches (open, laparoscopic or robotic), infection rates ranged from 0.9% to 12%. Regarding the risk factors for the development of this type of infection, antibiotic prophylaxis, female sex, high Body Mass Index and perioperative hyperglycemia are highlighted. Conclusion: conducting the integrative review generated a body of evidence that reinforces the importance of implementing effective measures for the prevention and control of surgical site infection, by health professionals, after bariatric surgery, promoting improved care and patient safety in the perioperative period.

Lifting the White Walker’s curse–Management of Coats’ disease

Background: Coats’ disease, described by George Coats in the early 1900s, is an idiopathic unilateral retinal vascular abnormality with exudation occurring in young males. It is characterized by retinal telangiectasia with intraretinal or subretinal exudation. Coats’ disease is mostly diagnosed in the first to the second decade of life, with a common presentation of leukocoria. Younger patients have a more severe presentation and are associated with poor visual prognosis. Management of Coats’ disease varies from observation, cryotherapy with anti?VEGFs (Vascular Endothelial Growth Factor), and surgery to enucleation. The mode of treatment depends on the age of presentation, the severity of the disease, and the stage of the disease. Through this video, we describe the clinical features, pathology, and surgical management of a 2?year?old child with grade 3B of Coats’ disease. Purpose: To demonstrate successful surgical management of grade 3B of Coats’ disease in a 2?year?old boy. Synopsis: Coats’ disease mostly presents with a diagnostic dilemma due to its varied presentation. Early detection and treatment are the keys to salvaging the eye as well as the vision, hence, avoiding dreadful complications such as neovascular glaucoma or phthisis bulbi. We demonstrate successful surgical management of a child who presented with grade 3B of Coats’ disease. Highlights: Through this video, we aim to describe the clinical features, pathology, and surgical management of a 2?year?old child with grade 3B of Coats’ disease. Combination of external drainage with vitrectomy, challenges faced, and the importance of visual rehabilitation postoperatively

What do retina fellows-in-training think about the vitreoretinal surgical simulator: A multicenter survey

Purpose: To profile vitreoretinal (VR) fellows?in?training from India exposed to the Eyesi surgical simulator, to identify potential barriers to voluntary use, and enumerate the most preferred tools and tasks before incorporating them into a formal skill?transfer curriculum. Methods: A questionnaire consisting of 22 questions was designed and circulated through an online portal (surveymonkey.com) to four different institutes of India having a VR surgical fellowship program and using a functional Eyesi (Haag–Streit) simulator. All fellows and trainees who were exposed to the simulator were eligible to participate, irrespective of time spent on the simulator and exposure to training steps on real patients. The responses collected were private and anonymous. Results: Of the 37 respondents, most (n = 25, 68%) considered surgical simulators to be the best training tool before operating on the human eye. A majority (n = 35, 94.5%) of participants spent <3 h per week on the simulator, which, most (n = 30, 81%) felt was not enough time. The main reasons for this underutilization were work?hour limitations (54.8%), lack of a structured training program (19.3%), or a dedicated supervisor (16.1%). Again, the majority (n = 33, 89%) of participants responded that VR surgical skills acquired during simulator training were transferrable to the operating room, which was reflected by their response (n = 31, 83.7%) that simulator?based training should be made mandatory before operating room exposure. Conclusion: This study gives an insight into the overall practice patterns and preferences in simulation training of surgical VR fellows?in?training across India. It indicates that the simulator is extremely helpful to fellows and if adopted, VR surgical simulators with organized, directed, and supervised sessions will considerably improve the surgical training experience.

Efficacy of Neoadjuvant Chemotherapy on Locally Advanced Gastric Adenocarcinoma in Terms of Downstaging and Resectability in a Tertiary Cancer Hospital

Background: Neoadjuvant chemotherapy (NACT) in carcinoma stomach was introduced in an effort to eliminate micro-metastasis and to improve resectablity before surgery which improves R0 resection rates. The aim of the current study was to evaluate the effect of neoadjuvant chemotherapy on downstaging and resectability rate in locally advanced gastric cancer. Material & Methods: This was a single-center quasi-experimental study conducted in the Department of Surgical Oncology in collaboration with the Departments of Medical Oncology, Radiation oncology, and Pathology at the National Institute of Cancer Research and hospital, Dhaka, which is a tertiary care cancer hospital in Bangladesh, between January 2021 and June 2022.Patients with locally advanced adenocarcinoma stomach staged by contrast-enhanced computed tomography (CECT) were randomly included in this study by purposive sampling. Patients in Group I underwent upfront surgery Patients in Group II were started on neoadjuvant chemotherapy, either XELOX or FLOT regimen. Surgery was done following the response assessment CECT. We assessed R0 resection rate, age, sex, comorbidities, tumour size, TNM stage and complications were compared between the two groups. Response to NACT was assessed in Group II. Results: The mean age of patients in groups 1 & 2 was 56 ± 11.06 and 55.70 ± 10.46 years of age respectively (p > 0.05). Majority of the respondents (55/74) were male and 19 patients (26%) were female. Male to female ratio was (24/37 &31/37) in group 1 and (31/37 & 6/37) groups respectively (p > 0.05). Out of 37 patients who received NACT, in 9 patients (24.32%) complete response was noted. Partial response was found in 20 cases (54.05%), p-value (<.0001) while a stable disease was reported in three (8.1%) cases. 5 patients (13.51%) had progressive disease. In the upfront surgery group, R0 resection was feasible in 16 (43.2%) cases, and in the NACT plus surgery group, R0 resection was done in 29 (78.4%) cases. In group 1, R1 resection was done in considerable numbers (19/37) compared to group 2 (5/37), P=0.001. Three patients (8.1%) in group 2 and one (2.7) in group 1 had irresectable lesions. Conclusion: In this study it can be concluded that neoadjuvant chemotherapy could downstage tumour and increase tumor resectability rate in patients with locally-advanced gastric adenocarcinoma. However, further studies are necessary to confirm the effect of this modality on patients’ overall survival. We await survival analysis to further validate the role of NACT.

Predictive factors and risk analysis of recurrent laryngeal nerve invasion in papillary thyroid carcinoma ≤ 1 cm

ABSTRACT Objective: The recurrent laryngeal nerve (RLN) may be involved by papillary thyroid carcinoma ≤ 1 centimeter (PTC ≤ 1 cm). Current study investigated the predictive factors of RLN invasion in PTC ≤ 1 cm, the risk factors of disease recurrence in RLN invaded cases and the results of surgical management for RLN invasion. Materials and methods: Data of 374 PTC ≤ 1 cm patients were retrospectively collected. We performed univariate and multivariate analysis to identify predictive factors of RLN invasion and risk factors of disease recurrence. The abilities of factors in predicting RLN invasion were evaluated. Surgical outcomes and recurrence free survival (RFS) of patients were analyzed. Results: A total of 28 patients suffered RLN invasion, among which seven had disease recurrence. Preoperative vocal cord palsy (VCP), gross extrathyroidal extension, larger tumor size and tumor on the dorsal side of thyroid were verified as predictive factors of RLN invasion. RLN involved patients had poorer RFS, but better than those who also had upper-aerodigestive tract invasion. Upper-aerodigestive tract invasion, lateral neck lymph nodes metastasis (LNM) and BRAF V600E mutation were independent risk factors of disease recurrence in RLN invaded cases. Tumor shaving showed better RLN function preservation without increasing recurrent risk. Conclusions: Current study confirmed the rarity of RLN invasion in PTC ≤ 1 cm. Various aggressive features were verified as predictive factors of RLN invasion. Tumor shaving showed superiority in preserving nerve function without increasing recurrent risk. Special attentions should be paid for disease recurrence when RLN invasion accompanied by upper-aerodigestive tract invasion, lateral neck LNM or BRAF V600E mutation.

Vacuum-assisted excision of breast lesions in surgical de-escalation: where are we? / Excisão assistida a vácuo de lesões mamárias no descalonamento cirúrgico: onde estamos?

Abstract Vacuum-assisted excision of breast lesions has come to be widely used in clinical practice. Increased acceptance and availability of the procedure, together with the use of larger needles, has allowed the removal of a greater amount of sample, substantially reducing the surgical upgrade rate and thus increasing the reliability of the results of the procedure. These characteristics result in the potential for surgical de-escalation in selected cases and gain strength in a scenario in which the aim is to reduce costs, as well as the rates of underestimation and overtreatment, without compromising the quality of patient care. The objective of this article is to review the technical parameters and current clinical indications for performing vacuum-assisted excision of breast lesions.

Resumo A excisão assistida a vácuo de lesões mamárias tem sido cada vez mais utilizada na prática clínica. A sua maior aceitação e disponibilidade, em associação ao uso de agulhas mais calibrosas, permitiu a retirada de quantidade maior de amostra, reduzindo substancialmente a taxa de subestimação diagnóstica e aumentando, assim, a confiabilidade final dos resultados do procedimento. Essas características resultam em potencial descalonamento cirúrgico, em casos selecionados, e ganham força em um cenário em que se visa a redução de custos, taxa de subestimação e tratamento excessivo, porém, sem comprometer a qualidade no cuidado com o paciente. O objetivo deste trabalho é revisar os parâmetros técnicos e as indicações clínicas atuais para realização de excisão assistida a vácuo em lesões mamárias.

Improvement in Nasal Obstruction and Quality of Life after Nasal Septoplasty with Turbinoplasty: A Pre- and Post-study

Abstract Introduction Septoplasty and turbinoplasty are common surgical interventions used to relieve nasal obstructive symptoms. Since it is difficult to measure the degree of nasal blockage, current literature wonders about the frequent performance of these procedures. Objective To evaluate the perceived change in the nasal obstruction and the quality of life (QoL) of patients that underwent a septoplasty along with a turbinoplasty by applying subjective scales, to describe the correlation between those scales, and to study the impact of clinical factors in the postoperative outcomes. Methods Prospective observational study. The Nasal Obstruction Symptom Evaluation (NOSE), the Visual Analog Scale (VAS), and the Glasgow Benefit Inventory (GBI) were assessed. The paired sample Wilcoxon test was used to evaluate the difference between the pre- and postoperative surveys. The correlation coefficient between the subjective scales was calculated. A quantile regression was performed to evaluate the effect of surgery on the results adjusted for clinical and demographic variables. Results A total of 115 patients were interviewed. Postoperative NOSE scores were 45 points lower (95% confidence interval [CI]: - 53.53-- 35.46; p < 0.001) in comparison with the NOSE preoperative scores. Obesity was the only statistically significant factor associated with worse outcomes. Additionally, we found a high correlation between the NOSE and VAS scores and a negative correlation between the GBI and postoperative VAS scores. Conclusion Nasal septoplasty, when paired with a turbinoplasty, decreases nasal obstruction and improves QoL. Obesity was associated with worse results. There was a strong correlation between the NOSE and the VAS results and between the GBI and postoperative VAS results.

The influence of 3D renal reconstruction on surgical planning for complex renal tumors: An interactive case-based survey

ABSTRACT Objectives To evaluate the role of three-dimensional (3D) reconstruction in preoperative planning for complex renal tumors. Materials and Methods A well-planned questionnaire was distributed among the attending urologists at an international meeting. The questionnaire inquired about demographic data, surgical experience, partial nephrectomy (PN) versus radical nephrectomy (RN), surgical approach, time of ischemia, probability of postoperative urine leakage and positive surgical margins after viewing computed tomography (CT) scans and their respective 3D models of six complex renal tumors. Following the CT scans, attendees were asked to view randomly selected reconstructions of the cases. Results One hundred expert urologists participated in the study; 61% were aged between 40 and 60 years. Most of them (74%) were consultants. The overall likelihood of PN after viewing the 3D reconstructions significantly increased (7.1±2.7 vs. 8.0±2.2, p<0.001), the probability of conversion to RN significantly decreased (4.3±2.8 vs. 3.2±2.5, p<0.001), and the likelihood of urine leakage and positive surgical margins significantly decreased (p<0.001). Preference for the open approach significantly decreased (21.2% vs. 12.1%, p<0.001), while selective clamping techniques significantly increased (p<0.001). After viewing the 3D models, low expected warm ischemia time and estimated blood loss were significantly preferred by the respondents (p<0.001). Surgical decision change was significantly associated with performance or participation in more than 20 PNs or RNs annually [3.25 (1.98-5.22) and 2.87 (1.43-3.87), respectively]. Conclusions 3D reconstruction models play a significant role in modifying surgeons' strategy and surgical planning for patients with renal tumors, especially for patients with stronger indications for a minimally invasive and/or nephron-sparing approach.

Perioperative mortality for radical cystectomy in the modern Era: experience from a tertiary referral center

ABSTRACT Purpose To evaluate the perioperative mortality and contributing variables among patients who underwent radical cystectomy (RC) for bladder cancer in recent decades, with comparison between modern (after 2010) and premodern (before 2010) eras. Materials and Methods Using our institutional review board-approved database, we reviewed the records of patients who underwent RC for primary urothelial bladder carcinoma with curative intent from January 2003 to December 2019. The primary and secondary outcomes were 90- and 30-day mortality. Univariate and multivariable logistic regression models were applied to assess the impact of perioperative variables on 90-day mortality. Results A total of 2047 patients with a mean±SD age of 69.6±10.6 years were included. The 30- and 90-day mortality rates were 1.3% and 4.9%, respectively, and consistent during the past two decades. Among 100 deaths within 90 days, 18 occurred during index hospitalization. Infectious, pulmonary, and cardiac complications were the leading mortality causes. Multivariable analysis showed that age (Odds Ratio: OR 1.05), Charlson comorbidity index ≥ 2 (OR 1.82), blood transfusion (OR 1.95), and pathological node disease (OR 2.85) were independently associated with 90-day mortality. Nevertheless, the surgical approach and enhanced recovery protocols had no significant effect on 90-day mortality. Conclusion The 90-day mortality for RC is approaching five percent, with infectious, pulmonary, and cardiac complications as the leading mortality causes. Older age, higher comorbidity, blood transfusion, and pathological lymph node involvement are independently associated with 90-day mortality.

Abnormalities in preoperative examinations of plastic surgery patients / Anormalidades em exames pré-operatórios de pacientes de cirurgia plástica

Introduction: Preoperative tests (EPO) aim to detect abnormalities and give greater safety to the procedure. However, the request for these tests is still controversial, either because they do not bring about changes in conduct for the procedure or result in some harm to the patient. The objective is to assess the frequency of EPO requests and abnormalities in aesthetic plastic surgery patients, to verify what these abnormalities are, what preoperative management should be done based on the finding, and to associate the data obtained with the patient's profile and the planned surgery. Method: Retrospective study evaluating medical records of aesthetic plastic surgery patients who underwent routine EPO in a plastic surgery hospital in 2019. Results: 978 patients were studied, and 51% had some abnormality in EPO. 93.7% were women, with a mean age of 46.5 years. 12.3 exams were performed per patient, and abnormality was observed in 6.1% of EPO. The exams that had the most abnormalities were the lipidogram (23.8%) and the cardiac evaluation (14.1%). Hypothyroidism was the most common comorbidity (18.4% of patients); 70% of diabetics had a glycemic level above the recommended level. Only 3.4% of the patients suffered a change in preoperative management due to EPO abnormality, and in 57.9% of these cases, the surgery was postponed. Test alterations were more frequent in male patients (p<0.0001). Conclusion: The performance of routine EPO showed a low frequency of altered exams (3.4%) and implied changes in the preoperative conduct of plastic surgery patients.

Introdução: Os exames pré-operatórios (EPO) visam detectar anormalidades e dar maior segurança ao procedimento. No entanto, a solicitação desses exames ainda é controversa, seja por não trazerem mudanças de conduta para o procedimento ou resultar em alguns malefícios para o paciente. O objetivo é avaliar a frequência de solicitações e de anormalidades dos EPO em pacientes de cirurgia plástica estética, verificar quais são estas anormalidades, qual conduta pré-operatória mediante o achado e associar os dados obtidos com o perfil do paciente e cirurgia prevista. Método: Estudo retrospectivo avaliando prontuários de pacientes de cirurgia plástica estética que realizaram EPO de rotina em um hospital de cirurgia plástica durante o ano de 2019. Resultados: Foram estudados 978 pacientes e 51% desses apresentaram alguma anormalidade nos EPO. 93,7% eram mulheres, com média de idade 46,5 anos. Foram realizados 12,3 exames por paciente e observada anormalidade em 6,1% dos EPO. Os exames que mais tiveram anormalidades foram o lipidograma (23,8%) e os da avaliação cardíaca (14,1%). Hipotireoidismo foi a comorbidade mais achada (18,4% dos pacientes); 70% dos diabéticos estavam com o nível glicêmico acima do recomendado. Apenas 3,4% dos pacientes sofreram alteração da conduta pré-operatória devido anormalidade dos EPO e em 57,9% desses casos houve adiamento da cirurgia. Alterações de exames foram mais frequentes em pacientes do sexo masculino (p<0,0001). Conclusão: A realização de EPO de rotina mostrou baixa frequência de exames alterados (3,4%) e implicou em mudanças na conduta pré-operatória em pacientes de cirurgia plástica.

Standardization of reconstructions with flaps after Fournier's gangrene / Padronização das reconstruções com retalhos após gangrena de Fournier

Introduction: Fournier's gangrene is characterized by tissue necrosis, which requires treatment employing debridement and antibiotics with wounds of varying sizes. The objective is to standardize the surgical techniques of reconstructions with flaps used to treat wounds after Fournier's gangrene. Method: A study was conducted by searching the PubMed/Medline, SciELO, and LILACS databases. Results: In wounds with skin loss of 25% to 50%, a local advancement cutaneous flap or a pudendal flap from the thigh was used; in wounds, greater than 50%, a superomedial thigh flap or myocutaneous flap from the gracilis muscle was used, with the aim of to enable proper reconstruction. Conclusion: Advancement and pudendal thigh flaps were used for wounds with up to 50% loss of scrotal skin substance, while the myocutaneous gracilis flap and supero-medial flap of the thigh were indicated for wounds with more than 50% of the total scrotal surface affected, after Fournier gangrene.

Introdução: Gangrena de Fournier é caracterizada por necrose tecidual, que necessita de tratamento por meio de desbridamento e antibióticos, com feridas de dimensões variadas. O objetivo é padronizar as técnicas cirúrgicas de reconstruções com retalhos utilizadas no tratamento das feridas após gangrena de Fournier. Método: Realizou-se estudo por meio da busca nas bases de dados PubMed/Medline, SciELO e LILACS. Resultados: Nas feridas com perdas cutâneas de 25% a 50%, foram utilizados retalho cutâneo local de avanço ou retalho pudendo da coxa, nas maiores de 50% foram necessárias as confecções do retalho superomedial da coxa ou retalho miocutâneo do músculo grácil, com intuito de possibilitar a reconstrução adequada. Conclusão: Os retalhos de avanço e pudendo da coxa foram utilizados para feridas com perda de substância cutânea escrotal de até 50%, enquanto os retalhos miocutâneo de músculo grácil e superomedial da coxa foram indicados para as feridas com mais de 50% da superfície escrotal total acometida, após gangrena de Fournier.

Marjolin ulcer: the importance of early diagnosis and excision / Úlcera de Marjolin: a importância do diagnóstico e excisão precoces

Introduction: Marjolin's ulcer is a rare disease characterized by the malignancy of chronic wounds that present healing disorders, often due to chronic irritation and repetitive trauma in this area. The diagnosis is made mainly through clinical history and histopathological examination. The differential diagnoses of other diseases that course with ulcers must always be researched and ruled out. Method: The present work presents a bibliographic review to elucidate the subject's relevance for medical students, physicians and nurses, to assist in early diagnosis. Results: Nine observational studies were selected to compose the discussion. Conclusion: The most effective treatment for this condition is surgery, and lymph node dissection is suggested in some cases. Chemotherapy has not shown satisfactory results, while radiotherapy is used in selected cases. Given the rapid evolution, tissue damage, and worse prognosis, diagnosis, and excision should be performed early for a better clinical outcome.

Introdução: A úlcera de Marjolin é uma doença rara, caracterizada pela malignização de feridas crônicas que apresentaram distúrbios cicatriciais, muitas vezes devido à irritação crônica e a traumas repetitivos nesta área. O diagnóstico é realizado sobretudo através da história clínica e de exame histopatológico. Os diagnósticos diferenciais de outras doenças que cursam com úlceras devem sempre ser pesquisados e afastados. Método: O presente trabalho apresenta uma revisão bibliográfica, a fim de elucidar a relevância do tema para acadêmicos de medicina, médicos e enfermeiros, com o propósito de auxiliar no diagnóstico precoce. Resultados: Foram selecionados 9 estudos observacionais para compor a discussão. Conclusão: O tratamento mais eficaz desta condição é o cirúrgico, e o esvaziamento linfonodal é sugerido em alguns casos. A quimioterapia não demonstrou resultados satisfatórios, enquanto a radioterapia é utilizada em casos selecionados. O diagnóstico e a excisão devem ser feitos precocemente para melhor desfecho clínico, visto a rapidez da evolução, o prejuízo tecidual e pior prognóstico.

Evaluation of the degree of aesthetic satisfaction after subcutaneous gluteal fat grafting / Avaliação do grau de satisfação estético após a lipoenxertia glútea subcutânea

Introduction: Body exposure, especially in the gluteal region, has increased the demand for gluteoplasty surgery. Autologous adipose tissue has been used to correct soft tissue defects since the beginning of the last century. Its smooth, natural texture, availability in sufficient quantities, and potentially permanent integration make adipose tissue the ideal physiological filler material. In this context, gluteal fat grafting, when compared with the use of gluteal implants, offers a faster recovery period and fewer complications in the medium and long term. Method: A prospective study was conducted using the gluteal evaluation questionnaire in patients who underwent subcutaneous gluteal fat grafting from August to December 2019. The collected data were submitted for statistical analysis by Student's t-test. Results: Forty patients (39 females and 1 male) who underwent subcutaneous gluteal fat grafting were selected. The average age presented in the study was 36.55 years. The mean body mass index was 27.38 kg/m2. The most frequent comorbidities were varicose veins, anemia, and hypertension. In most of the hypotheses evaluated, there was a significant improvement in the quality of life of the selected patients. Conclusions: Subcutaneous gluteal fat grafting improves patients' quality of life, which is demonstrated by the high level of satisfaction after performing this procedure.

Introdução: A exposição corporal, especialmente da região glútea, tem proporcionado atualmente um aumento da procura pela cirurgia de gluteoplastia. O tecido adiposo autólogo é usado para corrigir defeitos dos tecidos moles desde o início do século passado. Sua textura suave e natural, disponível em quantidades suficientes, e sua integração potencialmente permanente são características que fazem do tecido adiposo ser o material de preenchimento fisiológico ideal. Nesse contexto, a lipoenxertia glútea, quando comparada com o uso de implantes glúteos, oferece um período de recuperação mais rápido e menos complicações a médio e longo prazo. Método: Foi realizado um estudo prospectivo com a aplicação do questionário de avaliação dos glúteos nas pacientes submetidas a lipoenxertia glútea subcutânea no período de agosto a dezembro de 2019. Os dados coletados foram submetidos a análise estatística pelo teste t de Student. Resultados: Foram selecionados 40 pacientes (39 do sexo feminino e 1 do sexo masculino) que foram submetidos a lipoenxertia glútea subcutânea. A média da idade apresentada no estudo foi de 36,55 anos. A média do índice de massa corporal foi de 27,38 Kg/m2. As comorbidades mais frequentes foram varizes, anemia e hipertensão. Na maior parte das hipóteses avaliadas houve melhora significativa na qualidade de vida dos pacientes selecionados. Conclusões: A lipoenxertia glútea subcutânea melhora a qualidade de vida dos pacientes, o que é demonstrado pelo alto nível de satisfação após a realização desse procedimento.

Bevacizumab effect on viability of free groin flaps in rats / Efeito do bevacizumabe na viabilidade de retalho inguinal livre em ratos

Introduction: Bevacizumab is among the most frequently used drugs in cancer treatment. There is evidence that some anti-angiogenic drugs reduce flap survival, but it is unclear whether this applies to Bevacizumab. We investigated the effect of Bevacizumab on the viability of free flaps in rats. Methods: The animals were randomly assigned to one of three groups. The Graft group received intravascular saline and was submitted to a full-thickness skin graft. The Flap-Saline and the Flap- BVZ groups underwent a free groin flap after receiving, respectively, intravascular saline solution or intravascular administration of Bevacizumab. Results: The Graft group showed a lower percentage of the viable area (22.81%) relative to the Flap- Saline (83.98%; p<0.0001) and the Flap-BVZ groups (60.50%; p=0.0048). The lowest vascular pedicle patency was observed in the Flap-BVZ group, but the difference relative to the Flap-Saline was not significant (arteries, p=0.0867; veins, p=0.9999). A significant difference was observed in the occurrence of necrosis (p=0.0010), which was higher in the histological samples of the Graft (87.50%) and the Flap- BVZ (60.00%) relative to the Flap-Saline Group (0%). Inflammation occurred less frequently in the Flap-Saline (33.33%) compared to the Graft (87.5%) and Flap- BVZ group (70.00%), but the difference did not reach significance (p=0.0588). No significant differences emerged in the occurrence of hemorrhage or intraluminal thrombosis. Conclusion: The increase in inflammation, decrease in patency and reduction of viable area, though not significant, are in line with the histological analysis and call for further research on the potential adverse effects of the drug.

Introdução: Bevacizumabe é um dos fármacos mais utilizados no tratamento do câncer. Existem evidências de que drogas antiangiogênicas reduzem a taxa de sobrevivência dos retalhos, porém não está claro se isso se aplica ao bevacizumabe. Investigamos o efeito de bevacizumabe na viabilidade de retalhos livres em ratos. Método: Os animais foram randomizados em três grupos. O grupo Enxerto recebeu injeção intravenosa de soro fisiológico 0,9% (SF 0,9%) e foi submetido a uma enxertia de pele total. Os grupos Retalho-SF e Retalho-BVZ foram submetidos a retalhos inguinais livres e receberam injeções intravenosas, respectivamente, de SF 0,9% e Bevacizumabe. Resultados: O grupo Enxerto apresentou menor percentual de área de retalho viável (22,81%) em relação ao grupo Retalho-SF (83,98%; p<0,0001) e Retalho-BVZ (60,50%; p=0,0048). Os pedículos do grupo Retalho-BVZ apresentaram menor patência, mas a diferença em relação ao grupo Retalho-SF não foi significante (artérias, p=0,0867; veias, p=0,9999). A ocorrência de necrose foi significativamente maior nos grupos Enxerto (87,50%) e Retalho-BVZ (60,00%) em relação ao grupo Retalho-SF (0%) (p=0,0010). A ocorrência de inflamação foi menor no grupo Retalho-SF (33,33%) em relação aos grupos Enxerto (87,5%) e Retalho-BVZ (70,00%), porém essa análise não atingiu significância (p=0,0588). Não houve diferenças significantes na ocorrência de hemorragia ou trombose intraluminal entre os grupos. Conclusão: O aumento da inflamação, redução da patência e das áreas viáveis dos retalhos, apesar de não significantes, corroboram com efeitos deletérios do bevacizumabe evidenciados na análise histológica e demandam futuros estudos dos potenciais efeitos adversos da droga.

Postoperative radiotherapy with an electron beam on keloid scar: epidemiological evaluation in a teaching hospital / Radioterapia pós-operatória com feixe de elétrons sobre cicatriz queloideana: avaliação epidemiológica em hospital de ensino

Introduction: Keloids are one of the most aggressive spectrums of healing disorders. They have a unique pathophysiology and multiple specific genetic and cellular factors, which have not yet been fully elucidated. So far, literature reviews have found the influence of genetics, injury site, and ethnicity on the incidence and rate of recurrence. Furthermore, the need to associate an adjuvant method with surgical excision has already been verified, but the best therapy has yet to be defined. Method: A retrospective analysis of medical records was carried out to assess the profile of patients who underwent postoperative radiotherapy with an electron beam to treat keloids at the Hospital das Clínicas da Faculdade de Medicina de Botucatu between 2015 and 2019. Results: Data from 131 patients were evaluated, with 269 keloid scars treated. The average duration of treatment was 51 days, and the number of sessions was 17. White patients were predominant (78%) and women (70%), with surgical incision being the main cause of formation (49%) and ear the most identified location (33%). Women were more likely to complete the proposed treatment (p=0.04), while non-literates completed less than those who had at least completed primary or secondary education (p<0.0001). Conclusion: Postoperative radiotherapy for keloid scars is a well-established treatment in the literature and an important tool for plastic surgeons. Knowing the profile of patients who need this therapy is essential to create methods that improve adherence and results.

Introdução: Os queloides correspondem a um dos espectros mais agressivos dos distúrbios da cicatrização. Possuem fisiopatologia ímpar e múltiplos fatores genéticos e celulares específicos, ainda não totalmente elucidados. Até o momento, revisões literárias encontraram influência da genética, local da lesão e etnia sobre a incidência e taxa de recorrência. Ademais, já foi constatada a necessidade de associação de um método adjuvante com a excisão cirúrgica, mas ainda sem definição da melhor terapia. Método: Realizada uma análise retrospectiva de prontuários para avaliação do perfil dos pacientes submetidos a radioterapia pós-operatória com feixe de elétrons para o tratamento de queloides no Hospital das Clínicas da Faculdade de Medicina de Botucatu, entre 2015 e 2019. Resultados: Foram avaliados os dados de 131 pacientes, com um total de 269 cicatrizes queloideanas tratadas. A média da duração do tratamento foi de 51 dias e do número de sessões, de 17. Houve predominância de pacientes brancos (78%) e de mulheres (70%), sendo incisão cirúrgica a principal causa de formação (49%) e a orelha a localização mais identificada (33%). As mulheres tiveram mais chance de completar o tratamento proposto (p=0,04), enquanto os não alfabetizados completaram menos do que aqueles que tinham pelo menos ensino fundamental ou médio completo (p<0,0001). Conclusão: A radioterapia pós-operatória em cicatrizes queloideanas é um tratamento consagrado na literatura e uma importante ferramenta do cirurgião plástico. Conhecer o perfil dos pacientes que necessitam desta terapia é fundamental para criar métodos que melhorem a adesão e o resultado da mesma.
