ABSTRACT

ABSTRACT BACKGROUND: Minimally invasive distal pancreatectomy (MIDP) is associated with less blood loss and faster functional recovery. However, the benefits of robotic assisted distal pancreatectomy (RDP) over laparoscopic distal pancreatectomy (LDP) are unknown. AIMS: To compare RDP versus LDP for surgical treatment of benign lesions, pre-malignant and borderline malignant pancreatic neoplasias. METHODS: This is a retrospective study comparing LDP with RDP. Main outcomes were overall morbidity and overall costs. Secondary outcomes were pancreatic fistula (PF), infectious complications, readmission, operative time (OT) and length of hospital stay (LOS). RESULTS: Thirty patients submitted to LDP and 29 submitted to RDP were included in the study. There was no difference regarding preoperative characteristics. There was no difference regarding overall complications (RDP - 72,4% versus LDP - 80%, p=0,49). Costs were superior for patients submitted to RDP (RDP=US$ 6,688 versus LDP=US$ 6,149, p=0,02), mostly due to higher costs of surgical materials (RDP=US$ 2,364 versus LDP=1,421, p=0,00005). Twenty-one patients submitted to RDP and 24 to LDP developed pancreatic fistula (PF), but only 4 RDP and 7 LDP experienced infectious complications associated with PF. OT (RDP=224 min. versus LDP=213 min., p=0.36) was similar, as well as conversion to open procedure (1 RDP and 2 LDP). CONCLUSIONS: The postoperative morbidity of robotic distal pancreatectomy is comparable to laparoscopic distal pancreatectomy. However, the costs of robotic distal pancreatectomy are slightly higher.


RESUMO RACIONAL: A pancreatectomia distal minimamente invasiva (PDMI) está associada a menos perda sanguínea e recuperação funcional mais rápida, no entanto, os benefícios da pancreatectomia distal robótica (PDR) são desconhecidos quando comparada a pancreatectomia distal laparoscópica (PDL). OBJETIVOS: Comparar PDR versus PDL no tratamento cirúrgico de lesões benignas, neoplasias pancreáticas malignas, pré-malignas e limítrofes. MÉTODOS: Estudo retrospectivo comparando PDL com PDR. Os desfechos primários avaliados foram morbidade e custos hospitalares. Os desfechos secundários foram fístula pancreática (FP), complicações infecciosas, readmissão, tempo cirúrgico e tempo de internação hospitalar (TIH). RESULTADOS: Trinta pacientes submetidos a PDL e 29 submetidos a PDR foram incluídos no estudo. Não houve diferença em relação às características pré-operatórias. Não houve diferença em relação às complicações gerais (PDL - 72,4% versus PRD - 80%, p=0,49). Os custos foram superiores para PDR (PDR=US$ 6688 versus PDL=US$ 6149, p=0,02), principalmente devido aos custos mais elevados de materiais cirúrgicos (PDR=US$ 2364 versus PDL=1421, p=0,00005). Vinte e um pacientes submetidos a PDR e 24 submetidos a PDL desenvolveram fístula pancreática (PF), no entanto, apenas 4 submetidos PDR e 7 a PDL apresentaram complicações infecciosas associadas a FP. O tempo cirúrgico (PDR=224 min. versus PDL=213 min., p=0,36) e a conversão para cirurgia aberta (1 PDR e 2 PDL) não tiveram diferença estatística. CONCLUSÕES: A morbidade pós operatória da pancreatectomia distal robótica é comparável à pancreatectomia distal laparoscópica. Entretando, os custos da pancreatectomia distal robótica são mais elevados.

ABSTRACT

Abstract Introduction: Crohn's disease (CD) has been related to an increased prevalence of psychiatric disorders and suicide risk (SR). However, the nature of their relationship still deserves clarification. The aim of this study is to assess the prevalence of major depressive disorder (MDD) in patients with CD, and to investigate the relationship between MDD and CD outcomes. Methods: A cross-sectional study involving CD patients was performed. CD activity was evaluated by the Harvey-Bradshaw index and CD phenotype by the Montreal classification. The presence of MDD was assessed by the Patient Health Questionnaire score-9 (PHQ-9). Sociodemographic data and other characteristics were retrieved from electronic medical records. Results: 283 patients with CD were included. The prevalence of MDD was 41.7%. Females had a risk of MDD 5.3 times greater than males. CD disease duration was inversely correlated with MDD severity. Individuals with active CD were more likely to have MDD (OR = 796.0; 95% CI 133.7‒4738.8) than individuals with CD remission. MDD was more prevalent in inflammatory behavior (45.5%) and there were no statistical differences regarding the disease location. 19.8% of the sample scored positive for SR. Conclusion: The present results support data showing an increased prevalence of MDD in individuals with CD. Additionally, it indicates that MDD in CD might be related to the activity of CD. Prospective studies are warranted to confirm these results and to address whether MDD leads to CD activity, CD activity leads to MDD or both ways are existent.

ABSTRACT

Abstract Background & Aims Perianal fistulizing Crohn's disease is the main risk factor for anal cancer in patients with inflammatory bowel disease. Whether this occurs due to a higher frequency of human papillomavirus remains unclear. The authors aimed to evaluate the prevalence of HPV and high-risk HPV in patients with perianal Crohn's disease, compared with a control group. Methods The authors conducted a two-center cross-sectional study in which perianal fistulizing Crohn's disease patients were matched for age and sex with patients with anorectal fistula without Crohn's disease. Biopsy specimens were obtained from fistulous tracts during examination under anesthesia for both groups. The samples were sent for HPV detection and genotyping using the INNO-LiPA test. Results A total of 108 subjects (54 in each group) were recruited. The perianal fistulizing Crohn's disease group showed a statistically higher frequency of HPV in the fistulous tract than the control group (33.3% vs. 16.7%; p = 0.046). Separate analyses on high-risk types demonstrated that there was a numerically higher frequency of HPV in the perianal fistulizing Crohn's disease group. In multiple logistic regression, patients with perianal fistulizing Crohn's disease were found to have a chance of HPV 3.29 times higher than patients without Crohn's disease (OR = 3.29; 95% CI 1.20‒9.01), regardless of other variables. The types most frequently identified in the perianal fistulizing Crohn's disease group were HPV 11 (12.96%) and HPV 16 (9.26%). Conclusion Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV than in patients with anorectal fistula without Crohn's disease.

ABSTRACT

Abstract Objective: To evaluate the maximum and mean standardized uptake values, together with the metabolic tumor value and the total lesion glycolysis, at the primary tumor site, as determined by 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG-PET/CT), performed before and after neoadjuvant chemoradiotherapy (nCRT), as predictors of residual disease (RD) in patients with esophageal cancer. Materials and Methods: The standardized uptake values and the volumetric parameters (metabolic tumor value and total lesion glycolysis) were determined by 18F-FDG-PET/CT to identify RD in 39 patients before and after nCRT for esophageal carcinoma. We used receiver operating characteristic curves to analyze the diagnostic performance of 18F-FDG-PET/CT parameters in the definition of RD. The standard of reference was histopathological analysis of the surgical specimen. Results: Eighteen patients (46%) presented RD after nCRT. Statistically significant areas under the curve (approximately 0.72) for predicting RD were obtained for all four of the variables evaluated after nCRT. Considering the presence of visually detectable uptake (higher than the background level) at the primary tumor site after nCRT as a positive result, we achieved a sensitivity of 94% and a specificity of 48% for the detection of RD. Conclusion: The use of 18F-FDG-PET/CT can facilitate the detection of RD after nCRT in patients with esophageal cancer.


Resumo Objetivo: Avaliar os valores máximo e médio de captação padronizada, o valor metabólico do tumor e a glicólise total da lesão do local do tumor primário, medidos no estudo de 18F-FDG-PET/CT realizado antes e depois da quimiorradioterapia neoadjuvante (nQRT) em pacientes com câncer de esôfago, como preditores de doença residual (DR). Materiais e Métodos: Os valores máximo e médio de captação padronizada e os parâmetros volumétricos (valor metabólico do tumor e glicólise total da lesão) da 18F-FDG-PET/CT realizada em 39 pacientes antes e após a nQRT para carcinoma de esôfago foram avaliados para RD. Usamos curvas receiver operating characteristic (ROC) para analisar o desempenho diagnóstico dos parâmetros 18F-FDG-PET/CT na definição de RD. O estudo anatomopatológico foi utilizado como padrão ouro. Resultados: Dezoito pacientes (46%) apresentaram DR após a nQRT. Áreas estatisticamente significativas sob a curva ROC para predizer DR foram obtidas para as quatro variáveis nos estudos realizados após a nQRT, com áreas sob a curva ROC semelhantes em torno de 0,72. Considerando a presença de captação visualmente detectável (captação maior que o background) no local da lesão primária após a nQRT como resultado positivo, teríamos uma sensibilidade de 94% e uma especificidade de 48% para detecção de DR. Conclusão: A 18F-FDG-PET/CT pode ser útil para detectar a presença de doença neoplásica residual no câncer de esôfago após a nQRT.

ABSTRACT

ABSTRACT - BACKGROUND: At least 12 lymph nodes (LNs) should be examined following surgical resection of colon cancer. As it is difficult to find small LNs, fat clearing fixatives have been proposed, but there is no consensus about the best option. AIM: The objective of this study was to verify if Carnoy's solution (CS) increases the LN count in left colon cancer specimens. METHODS: A prospective randomized trial (clinicaltrials.gov registration: NCT02629315) with 60 patients with left colon adenocarcinoma who underwent rectosigmoidectomy. Specimens were randomized for fixation with CS or 10% neutral buffered formalin (NBF). After dissection, the pericolic fat from the NBF group was immersed in CS and re-dissected (Revision). The primary endpoint was the total number of LNs retrieved. RESULTS: Mean LN count was 36.6 and 26.8 for CS and NBF groups, respectively (p=0.004). The number of cases with <12 LNs was 0 (CS) and 3 (NBF, p=0.237). The duration of dissection was similar. LNs were retrieved in all cases during the revision (mean: 19, range: 4-37), accounting for nearly 40% of the LNs of this arm of the study. After the revision, no case was found in the NBF arm with <12 LNs. Two patients had metastatic LNs during the revision (no upstaging occurred). CONCLUSION: Compared to NBF, CS increases LN count in colon cancer specimens. After conventional pathologic analysis, fixing the pericolic fat with CS and performing a second dissection substantially increased the number of LNs.


RESUMO - RACIONAL: Pelo menos 12 linfonodos (LNs) devem ser examinados após a ressecção cirúrgica do câncer de cólon. Como é difícil encontrar LNs pequenos, fixadores de clareadores de gordura foram propostos, mas não há consenso sobre a melhor opção. OBJETIVO: Verificar se a solução de Carnoy (SC) aumenta o número de LNs obtidos em espécimes de câncer de cólon esquerdo. MÉTODOS: Ensaio prospectivo randomizado (clinictrials.gov: NCT02629315) com 60 pacientes com adenocarcinoma de cólon esquerdo submetidos à retossigmoidectomia. As amostras foram randomizadas para fixação com SC ou formalina tamponada neutra a 10% (NBF). Após a dissecção, a gordura pericólica do grupo NBF foi imersa em SC e redissecada (Revisão). O endpoint primário foi o número total de LNs recuperados. RESULTADOS: O número médio de LNs foi de 36,6 e 26,8 para os grupos CS e NBF, respectivamente (p=0,004). O número de casos com <12 LNs foi 0 (CS) e 3 (NBF, p=0,237). A duração da dissecção foi semelhante. LNs foram recuperados em todos os casos durante a revisão (média de 19, intervalo: 4-37), representando quase 40% dos LNs deste braço do estudo. Após a revisão, nenhum caso no braço NBF permaneceu com <12 LNs. Dois pacientes tiveram LNs metastáticos encontrados durante a revisão (não ocorreu upstaging). CONCLUSÃO: Em comparação com NBF, a SC aumenta a contagem de LNs em espécimes de câncer de cólon. Após a análise patológica convencional, a fixação da gordura pericólica com SC e a realização de uma segunda dissecção aumentaram o número de LNs.

ABSTRACT

ABSTRACT BACKGROUND: The enzyme methylenetetrahydrofolate reductase is engaged in DNA synthesis through folate metabolism. Inhibiting the activity of this enzyme increases the susceptibility to mutations, and damage and aberrant DNA methylation, which alters the gene expression of tumor suppressors and proto-oncogenes, potential risk factors for esophageal cancer. AIMS: This study aimed to investigate the association between methylenetetrahydrofolate reductase 677C>T and methylenetetrahydrofolate reductase 1298A>C polymorphisms and susceptibility to esophageal cancer, by assessing the distribution of genotypes and haplotypes between cases and controls, as well as to investigate the association of polymorphisms with clinical and epidemiological characteristics and survival. METHODS: A total of 109 esophageal cancer patients who underwent esophagectomy were evaluated, while 102 subjects constitute the control group. Genomic DNA was isolated from the peripheral blood buffy coat followed by amplification by polymerase chain reaction and real-time analysis. Logistic regression was used to assess associations between polymorphisms and the risk of developing esophageal cancer. RESULTS: There was no association for methylenetetrahydrofolate reductase 677C>T and methylenetetrahydrofolate reductase 1298A>C polymorphisms and haplotypes, with esophageal cancer susceptibility. Esophageal cancer patients carrying methylenetetrahydrofolate reductase 677TT polymorphism had higher risk of death from the disease. For polymorphic homozygote TT genotype, the risk of death significantly increased compared to wild-type genotype methylenetetrahydrofolate reductase 677CC (reference) cases (p=0.045; RR=2.22, 95%CI 1.02-4.83). CONCLUSIONS: There was no association between methylenetetrahydrofolate reductase 677C>T and methylenetetrahydrofolate reductase 1298A>C polymorphisms and esophageal cancer susceptibility risk. Polymorphic homozygote genotype methylenetetrahydrofolate reductase 677TT was associated with higher risk of death after surgical treatment for esophageal cancer.


RESUMO RACIONAL: A enzima metilenotetrahidrofolato redutase está envolvida na síntese de DNA através do metabolismo do folato. A inibição da sua atividade aumenta a suscetibilidade a mutações, danos e metilação aberrante do DNA, o que altera a expressão gênica de supressores tumorais e proto-oncogenes, potenciais fatores de risco para câncer de esôfago. OBJETIVOS: Investigar a associação entre os polimorfismos metilenotetrahidrofolato redutase 677C>T e metilenotetrahidrofolato redutase 1298A>C e a suscetibilidade ao câncer de esôfago, avaliando a distribuição de genótipos e haplótipos entre casos e controles, bem como investigar a associação de polimorfismos com características clínicas, epidemiológicas e sobrevida. MÉTODOS: Avaliaram-se 109 pacientes com câncer de esôfago submetidos à esofagectomia, enquanto 102 indivíduos constituaram o grupo controle. O DNA genômico do sangue periférico foi isolado e submetido à amplificação por reação em cadeia da polimerase em tempo real. A associação entre os polimorfismos e o risco de desenvolver câncer de esôfago foi avaliada por regressão logística. RESULTADOS: Não houve associação dos polimorfismos e haplótipos metilenotetrahidrofolato redutase 677C>T e metilenotetrahidrofolato redutase 1298A>C com a suscetibilidade ao câncer de esôfago. Pacientes com câncer de esôfago portadores do polimorfismo metilenotetrahidrofolato redutase 677TT apresentaram maior risco de morte pela doença. Para o genótipo TT homozigoto polimórfico, o risco de morte aumentou significativamente em comparação com os casos do genótipo selvagem metilenotetrahidrofolato redutase 677CC (referência) (p=0,045; RR=2,22, IC95% 1,02-4,83). CONCLUSÕES: Não houve associação entre os polimorfismos metilenotetrahidrofolato redutase 677C>T e metilenotetrahidrofolato redutase 1298A>C e o risco de suscetibilidade ao câncer de esôfago. O genótipo homozigoto polimórfico metilenotetrahidrofolato redutase 677TT associou-se a um maior risco de óbito após tratamento cirúrgico para câncer de esôfago.

ABSTRACT

ABSTRACT BACKGROUND: Esophageal cancer is an environment-related disease, and the most important risk factors are alcohol intake and smoking, in addition to gastroesophageal reflux in obese patients. The characterization of the patients' personality can contribute to the perception of how everyone adapts to the social environment and what relationship one can establish with themselves and with others. AIM: The aim of this study was to identify the psychological typology in patients with esophageal cancer. METHODS: The psychological typology of patients was defined using the Typological Assessment Questionnaire. In addition, the aspects of psychological assessment were studied to access the particularities of each patient, especially their reaction to the diagnosis and the meaning attributed to the disease. RESULTS: A total of 90 patients with esophageal cancer, aged over 18 years, who completed high school, and were interviewed at the first medical appointment, were included. The introverted attitude was predominant (83.33%). The most common psychological type was introverted sensation, with feeling as a secondary function (43.3%), and the second most frequent was introverted feeling, with sensation as a secondary function (24.4%). From this psychological assessment, a variety of defensive mechanisms were found to minimize distress. Most patients made use of adaptive defenses in the face of the illness process. CONCLUSION: The identification of the psychological typology allows the most effective assistance in directing the peculiar needs of each patient. In addition, it contributes to the care team to individualize treatments based on specific psychological characteristics.


RESUMO RACIONAL: O câncer de esôfago é uma doença relacionada ao meio ambiente, e os fatores de risco mais importantes são a ingestão de álcool e tabagismo, além do refluxo gastroesofágico em pacientes obesos. A caracterização da personalidade do paciente contribui para a percepção de como cada indivíduo se adapta ao meio social e que relação pode estabelecer consigo mesmo e com os outros. OBJETIVO: Identificar a tipologia psicológica em pacientes com câncer de esôfago. MÉTODOS: Definiu-se a tipologia psicológica utilizando o Questionário de Avaliação Tipológica. Estudaram-se os aspectos da avaliação psicológica para acessar as particularidades de cada um dos pacientes, principalmente no que diz respeito à sua reação ao diagnóstico e ao significado atribuído à doença. RESULTADOS: Foram incluídos noventa pacientes, com mais de 18 anos, ensino médio completo, diagnóstico de câncer de esôfago e que foram entrevistados na primeira consulta médica. A atitude introvertida foi a preponderante (83,33%). O tipo psicológico mais comum foi introvertido — sensação, tendo o sentimento como função secundária (43,3%), e introvertido — sentimento com sensação como função secundária foi o segundo tipo mais frequente (24,4%). A partir dessa avaliação psicológica, encontrou-se uma variedade de mecanismos defensivos para minimizar a angústia. A maioria dos pacientes fez uso de defesas adaptativas diante do processo de adoecimento. CONCLUSÕES: A identificação da tipologia psicológica permite o auxílio mais eficaz no direcionamento das necessidades peculiares de cada indivíduo. Além disso, contribui com a equipe de atendimento a fim de individualizar os tratamentos com base nas características psicológicas específicas.

ABSTRACT

ABSTRACT BACKGROUND: Robotic-assisted surgery research has grown dramatically in the past two decades and the advantages over traditional videolaparoscopy have been extensively debated. For hernias, the robotic system can increase intraoperative strategies, especially in complex hernias or incisional hernias. AIMS: This study aimed to compare the direct cost differences between robotic and laparoscopic hernia repair and determine each source of expenditure that may be related to the increased costs in a robotic program from the perspective of a Brazilian public institution. METHODS: This study investigated the differences in direct costs from the data generated from a trial protocol (ReBEC: RBR-5s6mnrf). Patients with incisional hernia were randomly assigned to receive laparoscopic ventral incisional hernia repair (LVIHR) or robotic ventral incisional hernia repair (RVIHR). The direct medical costs of hernia treatment were described in the Brazilian currency (R$). RESULTS: A total of 19 patients submitted to LVIHR were compared with 18 submitted to RVIHR. The amount spent on operation room time (RVIHR: 2,447.91±644.79; LVIHR: 1,989.67±763.00; p=0.030), inhaled medical gases in operating room (RVIHR: 270.57±211.51; LVIHR: 84.55±252.34; p=0.023), human resources in operating room (RVIHR: 3,164.43±894.97; LVIHR: 2,120.16±663.78; p<0.001), material resources (RVIHR: 3,204.32±351.55; LVIHR: 736.51±972.32; p<0.001), and medications (RVIHR: 823.40±175.47; LVIHR: 288.50±352.55; p<0.001) for RVIHR was higher than that for LVIHR, implying a higher total cost to RVIHR (RVIHR: 14,712.24±3,520.82; LVIHR: 10,295.95±3,453.59; p<0.001). No significant difference was noted in costs related to the hospital stay, human resources in intensive care unit and ward, diagnostic tests, and meshes. CONCLUSION: Robotic system adds a significant overall cost to traditional laparoscopic hernia repair. The cost of the medical and robotic devices and longer operative times are the main factors driving the difference in costs.


RESUMO RACIONAL: A pesquisa em cirurgia robótica assistida cresceu dramaticamente nas últimas duas décadas e as vantagens sobre a videolaparoscopia tradicional têm sido amplamente debatidas. Para as hérnias, o sistema robótico pode aumentar as estratégias intraoperatórias, principalmente em hérnias complexas ou hérnias incisionais. OBJETIVOS: Comparar as diferenças de custo direto entre a hernioplastia incisional robótica e a laparoscópica e determinar cada fonte de gasto que pode estar relacionada ao aumento de custos em um programa de robótica na perspectiva de uma instituição pública brasileira. MÉTODOS: Investigar as diferenças nos custos diretos dos dados gerados a partir de um protocolo de ensaio clínico (ReBEC: RBR-5s6mnrf). Pacientes com hérnia incisional foram aleatoriamente designados para serem submetidos a reparo robótico ou laparoscópico (RVIHR). Os custos foram descritos na moeda brasileira (R$). RESULTADOS: Dezenove pacientes submetidos à cirurgia robótica foram comparados com dezoito submetidos à cirurgia laparoscópica. O valor gasto com tempo de centro cirúrgico (Robótica: 2.447,91±644,79; Robótica: 1.989,67±763,00; p=0,030), gases medicinais inalados em centro cirúrgico (Robótica: 270,57±211,51; Robótica: 84,55±252,34; p=0,023), recursos humanos em centro cirúrgico (Robótica: 3.164,43±894,97; Laparoscópica: 2.120,16±663,78; p<0,001), recursos materiais (Robótica : 3.204,32±351,55; Robótica: 736,51±972,32; p<0,001) e medicamentos (Robótica: 823,40±175,47; Robótica: 288,50 ± 352,55; p<0,001) para cirurgia robótica foi maior que cirurgia laparoscópica, implicando em maior custo total para cirurgia robótica (Robótica: 14.712,24±3.520,82; Laparoscópica: 10.295,95±3.453,59; p<0,001). Não foi observada diferença significativa nos custos relacionados à permanência hospitalar, recursos humanos em UTI e enfermaria, exames diagnósticos e telas. CONCLUSÕES: O sistema robótico adiciona um custo global significativo à hernioplastia incisional laparoscópica tradicional. O custo dos dispositivos médicos e robóticos, além de tempos cirúrgicos mais prolongados, são os principais fatores que impulsionam a diferença nos custos.

ABSTRACT

ABSTRACT Background: Nearly 10% of node negative gastric cancer patients who underwent curative surgery have disease recurrence. Western data is extremely poor on this matter and identifying the risk factors that associate with relapse may allow new strategies to improve survival. Aim: Verify the clinical and pathological characteristics that correlate with recurrence in node negative gastric cancer. Methods: All gastric cancer patients submitted to gastrectomy between 2009 and 2019 at our institution and pathologically classified as N0 were considered. Their data were available in a prospective database. Inclusion criteria were: gastric adenocarcinoma, node negative, gastrectomy with curative intent, R0 resection. Main outcomes studied were: disease-free survival and overall survival. Results: A total of 270 patients fulfilled the inclusion criteria. Mean age was 63-year-old and 155 were males. Subtotal gastrectomy and D2 lymphadenectomy were performed in 64% and 74.4%, respectively. Mean lymph node yield was 37.6. Early GC was present in 54.1% of the cases. Mean follow-up was 40.8 months and 19 (7%) patients relapsed. Disease-free survival and overall survival were 90.9% and 74.6%, respectively. Independent risk factors for worse disease-free survival were: total gastrectomy, lesion size ≥3.4 cm, higher pT status and <16 lymph nodes resected. Conclusion: In western gastric cancer pN0 patients submitted to gastrectomy, lymph node count <16, pT3-4 status, tumor size ≥3.4 cm, total gastrectomy and presence of lymphatic invasion, are all risk factors for disease relapse.


RESUMO Racional: Aproximadamente 10% dos pacientes com câncer gástrico submetidos a operação curativa e sem linfonodos acometidos irão apresentam recorrência da doença. Os dados ocidentais são extremamente pobres sobre este assunto e a identificação dos fatores de risco associados à recidiva podem permitir novas estratégias para melhorar a sobrevida. Objetivo: Identificar as características clínicas e patológicas que se correlacionam com recidiva em pacientes com câncer gástrico pN0. Métodos: Foram considerados todos os pacientes com câncer gástrico submetidos à gastrectomia entre 2009 e 2019 em nossa instituição e que na classificação patológica não apresentaram acometimento linfonodal. Os critérios de inclusão foram: adenocarcinoma gástrico, pN0, gastrectomia com intenção curativa, ressecção R0. Os principais desfechos estudados foram: sobrevida livre de doença e sobrevida global. Resultados: Ao todo 270 pacientes preencheram os critérios de inclusão. A idade média foi de 63 anos e 155 eram homens. A gastrectomia subtotal e a linfadenectomia D2 foram realizadas em 64% e 74,4%, respectivamente. A média de linfonodos ressecados foi de 37,6. Câncer gástrico precoce estava presente em 54,1% dos casos. O seguimento médio foi de 40,8 meses e 19 (7%) apresentaram recidiva. A sobrevida livre de doença e sobrevida global foram de 90,9% e 74,6%, respectivamente. Os fatores de risco independentes para pior sobrevida livre de doença foram: gastrectomia total, lesão ≥3,4 cm, status pT avançado e <16 linfonodos ressecados. Conclusão: Os fatores de risco para recidiva no grupo estudado foram: <16 linfonodos ressecados, status pT3-4, tumor ≥3,4 cm, gastrectomia total e presença de invasão linfática.

ABSTRACT

ABSTRACT Background: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.


RESUMO Racional: O tratamento da doença hemorroidária pela técnica de THD (Transanal Hemorrhoidal Dearterialization) é minimamente invasivo e tem se mostrado seguro e eficiente. No entanto, dados sobre a recorrência e complicações (dor e tenesmo) no pós-operatório são muito variáveis. Objetivo: Avaliar se a desarterialização e mucopexia seletiva, sem o uso de Doppler, é suficiente para o controle de sintomas e se a morbidade pós-operatória é menor com esta técnica. Métodos: Vinte pacientes foram tratados com essa técnica e avaliados sobre controle de sintomas, morbidade pós-operatória e recorrência. Resultados: Controle do prolapso e sangramento foi observado em todos pacientes (n=20). Complicações pós-operatórias foram: tenesmo (n=2), trombose hemorroidária externa (n=2), retenção urinária (n=2). Após um seguimento médio de 13 meses, nenhuma recorrência foi detectada. Conclusões: O procedimento de desarterialização e mucopexias seletivas é seguro e eficiente em termos de controle do prolapso e sangramento. Esta técnica resulta em menor morbidade cirúrgica, uma vez que diminui o número de suturas no canal anal, resultando em menos dor e tenesmo pós-operatório. Para este procedimento o uso de ultrassom Doppler é desnecessário, o que diminui custos e o torna mais atrativo do ponto de vista econômico.

ABSTRACT

ABSTRACT Background: Due to the lack of normal standards of anorectal manometry in Brazil, data used are subject to normality patterns described at different nationalities. Aim: To determine the values and range of the parameters evaluated at anorectal manometry in people, at productive age, without pelvic floor disorders comparing the parameters obtained between male and female. Methods: Prospective analysis of clinical data, such as gender, age, race, body mass index (BMI) and anorectal manometry, of volunteers from a Brazilian university reference in pelvic floor disorders. Results: Forty patients were included, with a mean age of 45.5 years in males and 37.2 females (p=0.43). According to male and female, respectively in mmHg, resting pressures were similar (78.28 vs. 63.51, p=0.40); squeeze pressures (153.89 vs. 79.78, p=0.007) and total squeeze pressures (231.27 vs. 145.63, p=0.002). Men presented significantly higher values of anorectal squeeze pressures, as well as the average length of the functional anal canal (2.85 cm in male vs. 2.45 cm in female, p=0.003). Conclusions: Normal sphincter pressure levels in Brazilians differ from those used until now as normal literature standards. Male gender has higher external anal sphincter tonus as compared to female, in addition a greater extension of the functional anal canal


RESUMO Racional: Devido à falta de padrões normais de manometria anorretal no Brasil, os dados utilizados estão sujeitos a padrões de normalidade descritos em diferentes nacionalidades . Objetivo: Determinar os valores e a faixa da manometria anorretal de pessoas em idade produtiva, sem distúrbios do assoalho pélvico, comparando os parâmetros obtidos entre homens e mulheres. Métodos: Análise prospectiva de dados clínicos, como gênero, idade, raça, índice de massa corporal (IMC) e manometria anorretal, de voluntários de uma referência universitária brasileira em distúrbios do assoalho pélvico. Resultados: Quarenta pessoas foram incluídas, com idade média de 45,5 anos nos homens e 37,2 nas mulheres (p=0,43). De acordo com homens e mulheres, respectivamente em mmHg, as pressões de repouso foram semelhantes (78,28 vs. 63,51, p=0,40); pressões de contração (153,89 vs. 79,78, p=0,007) e pressão total de compressão (231,27 vs. 145,63, p=0,002). Os homens apresentaram valores significativamente maiores de contração esfincteriana, assim como o comprimento médio do canal anal funcional (2,85 cm nos homens vs. 2,45 cm nas mulheres, p=0,003). Conclusões: Os níveis normais de pressão esfincteriana no Brasil diferem dos utilizados até o momento como padrão normal da literatura. O gênero masculino apresenta maior tônus ​​do esfíncter anal externo em relação ao feminino, além de maior extensão do canal anal funcional

ABSTRACT

OBJECTIVES: Since the outbreak of the novel coronavirus disease 2019 (COVID-19), all health services worldwide underwent profound changes, leading to the suspension of many elective surgeries. This study aimed to evaluate the safety of elective colorectal surgery during the pandemic. METHODS: This was a retrospective, cross-sectional, single-center study. Patients who underwent elective colorectal surgery during the COVID-19 pandemic between March 10 and September 9, 2020, were included. Patient data on sex, age, diagnosis, types of procedures, hospital stay, mortality, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preoperative screening tests were recorded. RESULTS: A total of 103 colorectal surgical procedures were planned, and 99 were performed. Four surgeries were postponed due to positive preoperative screening for SARS-CoV-2. Surgical procedures were performed for colorectal cancer (n=90) and inflammatory bowel disease (n=9). Laparoscopy was the approach of choice for 43 patients (43.4%), 53 (53.5%) procedures were open, and 3 (3%) procedures were robotic. Five patients developed COVID-19 in the postoperative period, and three of them died in the intensive care unit (n=3/5, 60% mortality). Two other patients died due to surgical complications unrelated to COVID-19 (n=2/94, 2.1% mortality) (p<0.01). Hospital stay was longer in patients with SARS-CoV-2 infection than in those without (38.4 versushttps://doi.org/10.3 days, respectively, p<0.01). Of the 99 patients who received surgical care during the pandemic, 94 were safely discharged (95%). CONCLUSION: Our study demonstrated that elective colorectal surgical procedures may be safely performed during the pandemic; however, preoperative testing should be performed to reduce in-hospital infection rates, since the mortality rate due to SARS-CoV-2 in this setting is particularly high.

ABSTRACT

ABSTRACT Objective: To evaluate telephone monitoring for symptoms, quality of life, distress, admissions to the emergency center and the satisfaction of cancer patients undergoing esophagectomy and gastrectomy. Method: Randomized controlled study in two groups, carried out at the Cancer Institute of the State of Sao Paulo; the intervention group received telephone monitoring for four moments after the surgery, while the control group received only institutional care. Results: Of the 81 patients evaluated, the domain most affected by quality of life was social relationships domain. Distress had no significant difference between groups and moments. In both groups, admissions to the emergency center were similar (p=0.539). Pain was the most reported symptom in telephone monitoring. There was statistical significance regarding patient satisfaction with monitoring (p=0.002). Conclusion: Telephone monitoring provided greater patient satisfaction in the intervention group, demonstrating the real impact of this process on the care of cancer patients.


RESUMEN Objetivo: Evaluar el monitoreo telefónico en los síntomas, en la calidad de vida, en el distrés, en las admisiones en el centro de emergencias y en la satisfacción del paciente oncológico sometido a esofagectomía y gastrectomía. Método: Se trata de un estudio aleatorizado en dos grupos, realizado en el Instituto del Cáncer del Estado de São Paulo, en el que el grupo intervención recibió el monitoreo telefónico en cuatro momentos tras la cirugía, mientras que el grupo control recibió solamente la atención institucional. Resultados: De los 81 pacientes evaluados, el dominio más afectado en la calidad de vida fue el desempeño del papel. El distrés no mostró diferencia entre los grupos y los momentos. En ambos grupos, las admisiones en el centro de emergencia eran similares (p=0,539). El dolor era el síntoma más informado en el monitoreo telefónico. Se encontró una significación estadística relacionada con la satisfacción del paciente y el monitoreo (p=0,002). Conclusión: El monitoreo telefónico brindó más satisfacción a los pacientes en el grupo intervención y demostró el impacto real de este proceso en el cuidado del paciente oncológico.

ABSTRACT

ABSTRACT Background: The octogenarian population is expanding worldwide and demand for gastrectomy due to gastric cancer in this population is expected to grow. However, the outcomes of surgery with curative intent in this age group are poorly reported and it is unclear what matters most to survival: age, clinical status, disease´s stage, or the extent of the surgery performed. Aim: Evaluate the results of gastrectomy in octogenarians with gastric cancer and to verify the factors related to survival. Methods: From prospective database, patients aged 80 years or older with histologically confirmed adenocarcinoma who had undergone gastrectomy with curative intent were selected. Factors related to postoperative complications and survival were studied. Results: Fifty-one patients fulfilled the inclusion criteria. A total of 70.5% received subtotal gastrectomy and in 72.5% D1 lymphadenectomy was performed. Twenty-five (49%) had complications, in eleven major complications occurred (seven of these were clinical complications). Hospital length of stay was longer (8.5 vs. 17.8 days, p=0.002), and overall survival shorter (median of 1.4 vs. 20.5 months, p=0.009) for those with complications. D2 lymphadenectomy and the presence of postoperative complications were independent factors for worse overall survival. Conclusion: Octogenarians undergoing gastrectomy with curative intent have high risk for postoperative clinical complications. D1 lymphadenectomy should be the standard of care in these patients.


RESUMO Racional: A população octogenária está expandindo mundialmente e é esperado que a demanda por gastrectomia devido a câncer gástrico nessa faixa também aumente. Entretanto, os resultados da operação curativa nessa população são pobremente reportados e não está claro o que mais importa no resultado: idade, status clínico, estágio da doença, ou a extensão da operação. Objetivos: Avaliar os resultados cirúrgicos da gastrectomia em octogenários e verificar os fatores relacionados com a sobrevida. Métodos: Através de revisão de banco de dados prospectivo, pacientes com 80 anos ou mais de idade e adenocarcinoma gástrico comprovado histologicamente e submetidos a gastrectomia com intuito curativo foram analisados. Fatores relacionados a complicações pós-operatórias e sobrevida foram estudadas. Resultados: Cinquenta e um pacientes preencheram os critérios de inclusão. A gastrectomia subtotal foi realizada em 70,5% dos casos e a linfadenectomia D1 em 72,5% dos pacientes. Complicações ocorreram em 25 pacientes (49%), sendo que em 11 elas foram graves (sete foram complicações clínicas). Pacientes com complicações tiveram maior duração da internação hospitalar (8,5 vs. 17,8 dias, p=0,002) e sobrevida global mais curta (mediana de 1,4 vs. 20,5 meses, p=0,009). Linfadenectomia D2 e a presença de complicações foram fatores independentes de pior sobrevida global. Conclusão: Os octogenários submetidos à gastrectomia com intenção curativa apresentam alto risco de complicações clínicas no pós-operatório. A linfadenectomia D1 deve ser o padrão de atendimento nesses pacientes.

ABSTRACT

OBJECTIVE: Stoma prolapse is an intussusception of the bowel through a mature stoma. It can be caused by increased intra-abdominal pressure, excessively mobile bowel mesentery and/or a large opening in the abdominal wall at the time of stoma formation. It occurs predominantly in loop stomas, and correction methods include conservative modalities, such as local reduction to the prolapsed bowel, or surgical treatment. The purpose of this study was to describe our experience with the treatment of colostomy prolapse using a novel mesh strip technique. METHODS: Between February 2009 and March 2018, ten consecutive male patients underwent correction of colostomy prolapse under local anesthesia by peristomal placement of a polypropylene mesh strip. Operation time, short- and long-term complications, and recurrence rates were recorded and analyzed. RESULTS: No postoperative complications, morbidity or mortality were observed. The median length of the prolapse ranged from 6-20 cm, and the median operative time was 30 minutes. The median duration of follow-up was 25 months (range, 12-89 months). No relapse, mesh strip extrusion, local infection or granuloma formation were found. CONCLUSION: A simple, fast, and low-cost operation under local anesthesia using a mesh strip is a valuable option to treat colostomy prolapse.
