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.

The three techniques have equivalent delayed graft function as well as patient and graft survival rates. This is an encouraging result as it means that the surgeon can choose to use the technique which is most appropriate for their own skills and for the patient.
Background: Biologic and synthetic meshes are used in immediate implant-based breast reconstruction for coverage of the lower pole of the implant. This study aimed to compare outcomes of Veritas with TiLOOP bra (TiLOOP group [TG]). Methods: Retrospective study of skin- and nipple-sparing mastectomies in patients who underwent an implant-based reconstruction using either Veritas or TiLOOP bra between January 2014 and December 2016 was performed. Results: Thirty-six reconstructions (22 unilateral, 7 bilateral) using the Veritas mesh and 179 breast reconstructions (61 unilateral, 59 bilateral) using TiLOOP bra were identified. The Veritas group (VG) showed a higher rate of postoperative complications compared with the TG (VG = 54% versus TG = 14%, P < 0.01%), including higher rates of seroma, nonintegration of mesh (VG = 51.4% versus TG = 1.6%, P < 0.01), implant rotation (VG = 16.2% versus TG = 1.6%, P < 0.01), infection (VG = 18.9% versus TG = 2.1%, P < 0.01), and wound breakdown (VG = 10.8% versus TG = 0.5%, P < 0.01). The VG also had a higher rate of major interventions (VG = 35.1% versus TG = 7.8%, P < 0.01) and minor interventions (VG = 18.9% versus TG = 2.2%, P < 0.01) compared with TG, including a higher rate of implant loss and unplanned return to theater. Conclusions: Veritas mesh was associated with a significantly higher rate of postoperative complications compared with TiLOOP bra. Our data strongly question the safety profile of Veritas in implant-based breast reconstruction. Further studies in this area are warranted.
Background: Penetrating abdominal trauma is uncommon in Australia. There are multiple potential approaches to the patient without an indication for immediate laparotomy. This study examined the management of patients with a penetrating anterior abdominal injury in a Level 1 trauma centre, and in particular investigated the outcomes of those patients who underwent diagnostic laparoscopy. Methods: A retrospective review was undertaken of all patients presenting to a Level 1 trauma centre with an anterior abdominal stab wound over a 15-year period. Patient demographic, injury, examination, treatment and outcome data were extracted. These data were analysed using SPSS PASW version 20. Results: A total of 318 patients were identified. Immediate laparotomy was performed in 121 of those patients. Of the remaining 197 patients, 146 underwent diagnostic laparoscopy. Peritoneal breach was identified in 87 patients, 79 of whom then had exploratory laparotomy. The laparotomy was therapeutic in 36 of 79 patients (45.6%). Multiple stab wounds were an independent predictor of therapeutic laparotomy (hazard ratio 2.39, 95% CI 1.16-4.93). Diagnostic laparoscopy was 100% sensitive, 60.9% specific and had a negative predictive value of 100% and a positive predictive value of 40%. Non-therapeutic laparotomy was associated with a median length of stay of 5.5 days and a complication rate of 9.3%. Conclusion: Diagnostic laparoscopy to detect peritoneal breach is a safe approach in the management of anterior abdominal stab wounds. However, utilizing peritoneal breach as an indication for laparotomy is associated with a moderate incidence of non-therapeutic laparotomy. Measures to decrease the negative laparotomy rate should be considered.
