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.

deviation). Results: A total of 75 patients (83% female) met the inclusion criteria with 67% completing the DLQI assessment. The mean number of treatments over the study period was 12 (AE 3.1) while mean age was 37.6 years (AE 8.82). Mean overall DLQI score was 1.6 (AE 2.01), which was an improvement of mean overall score of 12.2 (AE 8.0) from previously published validated data. Relationship related scores were mean 0.53 (AE 0.8). Conclusion: These data suggest that known benefits of botulinum toxin treatment on QOL are sustained in the long term. However, there is a requirement for randomised data to confirm this hypothesis.

The value of infusion cholecystography 99mTc HIDA cholescintigraphy and ultrasonography was compared in 51 patients presenting with a clinical diagnosis of acute cholecystitis. Of the 35 patients with proven gallbladder disease, the presence of gallstones was correctly predicted in 31 (88 per cent) by infusion cholecystography, 32 (90 per cent) by 99mTc HIDA cholescintigraphy and 27 (77 per cent) by ultrasonography. There were no false positive investigations. Infusion cholecystography may be of particular interest to surgeons with no ready access to isotope scanning techniques.
