SUMMARY In the emergency care of cancer patients, in addition to cancer-related factors, two aspects influence the outcome: (1) where the patient is treated and (2) who will perform the surgery. In Brazil, a significant proportion of patients with surgical oncological emergencies will be operated on in general hospitals by surgeons without training in oncological surgery. OBJECTIVE: The objective was to discuss quality indicators and propose the creation of an urgent oncological surgery advanced life support course. METHODS: Review of articles on the topic. RESULTS: Generally, nonelective resections are associated with higher rates of morbidity and mortality, as well as lower rates of cancer-specific survival. In comparison to elective procedures, the reduced number of harvested lymph nodes and the higher rate of positive margins suggest a compromised degree of radicality in the emergency scenario. CONCLUSION: Among modifiable factors is the training of the emergency surgeon. Enhancing the practice of oncological surgery in emergency settings constitutes a formidable undertaking that entails collaboration across various medical specialties and warrants endorsement and support from medical societies and educational institutions. It is time to establish a national registry encompassing oncological emergencies, develop quality indicators tailored to the national context, and foster the establishment of specialized training programs aimed at enhancing the proficiency of physicians serving in emergency services catering to cancer patients. cancerrelated related outcome 1 (1 2 (2 Brazil OBJECTIVE course METHODS topic RESULTS Generally mortality cancerspecific specific survival procedures scenario CONCLUSION surgeon institutions context (

Abstract ASTM A 182 F22 steel, used in components subsea for oil extraction, are previously buttered with ductile metal such as Inconel 625, before being welded to steel pipes similar to ASTM A36 steels. The thermal buttering weld cycle provides the formation of high hardness micro-phases and carbides at the interface between F22 steel and the buttering with Inconel, which when in contact with hydrogen, originating from the cathodic protection applied to these equipment, can lead to the embrittlement of this region, causing fragile fractures. In this work, ASTM A 182 F22 steel, buttered with Inconel 625 and welded to A36 steel, submitted to post-weld heat treatment without hydrogenation and subjected to cathodic protection for hydrogen permeation were submitted to fracture toughness test. The welds and buttering were done using GMAW process with AWS ERNiCrMo-3 wire as filler and buttering metal and a mixture of Ar and He as shield gas. The results indicated a 56% of area reduction, and 15% in the elongation values in the tensile tests, in addition to a 13.3% reduction in the CTOD value, for welded joints subjected to hydrogen permeation, which showed a quasi-cleavage fracture mechanism.

O câncer de cólon é uma doença de alta prevalência e mortalidade, cujo tratamento baseia-se na ressecção cirúrgica. A possibilidade de cura aumenta com o diagnóstico precoce, daí a importância dos programas de rastreamento populacional do câncer colorretal. O presente estudo analisou, retrospectivamente, 66 pacientes submetidos a ressecções do cólon por neoplasia em um período de 58 meses no Hospital Universitário da Universidade de São Paulo. Os pacientes foram divididos em dois grupos: grupo 1, submetidos a cirurgia eletiva (28 pacientes), e grupo 2, submetidos a cirurgia de urgência (38 pacientes). Os grupos foram comparados com relação às variáveis sexo, idade, apresentação clínica, aspectos da técnica cirúrgica, sítio anatômico da lesão, estádio patológico, taxas de complicações, permanência hospitalar pós-operatória e óbitos na internação. Verificou-se no presente estudo que a idade entre os grupos foi semelhante. Houve uma predominância do sexo masculino entre os pacientes operados de urgência. No grupo de cirurgia eletiva, o principal sintoma foi a hematoquezia, enquanto os operados na urgência, tinham como principal queixa dor abdominal. A grande maioria dos pacientes, no momento da cirurgia, apresentava-se sintomática há meses. Os pacientes operados na urgência apresentaram mais tumores pT4 e os operados eletivamente apresentaram mais neoplasias em estádio I. Em ambos os grupos, o caráter oncológico dos procedimentos foi preservado, bem como foi alto o índice de anastomoses primárias (81,8%). As taxas de complicações pós-operatórias, o tempo de permanência hospitalar pós-operatório e a mortalidade foram semelhantes.

Colon cancer is a disease with high frequency and mortality rates, which treatment is based, fundamentally, on surgical resection. Because early diagnosis increases the curability, it is essential to have a screening programs offering early treatment. A retrospective study was performed, including 66 patients who underwent colonic resections due to cancer, for 58 months at Hospital Universitario of Universidade de São Paulo. These patients were divided in two groups, group 1, submitted to elective surgery (28 patients), and group 2, submitted to emergency surgery (38 patients). The groups were comparable for gender, age, clinical presentation, surgical procedure techniques, tumor distribution, TNM stage, morbidity, postoperative hospital stay and postoperative mortality. No difference was observed in patients’age. Males were predominant in the urgency surgery group. Lower gastrointestinal bleeding was the main symptom in the elective group, whereas abdominal pain was the main symptom in the urgency group. Mostly of the patients were having symptoms for months at the time of surgery. Urgency group patients presented more pT4 tumors, and elective group patients presented more stage I cancer. In both groups the oncologic approach was achieved, as well as primary anastomosis rates (81.8%). No differences in average hospital stay, hospital morbidity or postoperative mortality were recorded.
