Summary Background 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov , NCT03471494 . Findings Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

PCR is more sensitive in detecting bacterial contamination of gallbladder bile in cholecystitis than conventional culture. The clinical relevance of this high sensitivity remains unclear.
Este estudo teve como objetivo analisar a ocorrência de complicações em pacientes submetidos à colostomia e reconstrução do trânsito intestinal. Para isto, estudou-se 56 pacientes, com idade média de 39 anos, sendo 37 homens e 19 mulheres. As principais indicações para a colostomia foram ferimento por arma de fogo (35%), doença diverticular perfurada (12,5%) e câncer colo-retal (12%). O tipo de colostomia mais realizado foi terminal (70%), com utilização do sigmóide em 71,4% dos casos. O tempo médio de permanência da colostomia foi de 5,5 meses. A reconstrução do trânsito foi realizada através de anastomose término-terminal em 85,7% dos pacientes, através de síntese mecânica com stapler circular em 5 pacientes ou manual em 51 pacientes. Observou-se taxa de complicações de 25%, sendo as mais frequentes a infecção de parede (35,7%), as fístulas (28,6%) e a hemorragia digestiva baixa (21,4%). Conclui-se que a reconstrução do trânsito intestinal não está isenta de riscos cirúrgicos e apresenta taxas consideráveis de complicações pós-operatórias, sendo que a infecção continua a ser um dos maiores desafios existentes neste procedimento.
