    Background. Variceal bleeding (VB) is the leading cause of death in cirrhotic patients with oesophageal varices. We evaluated the efficacy of emergency endoscopic intervention in controlling acute variceal bleeding and preventing rebleeding and death during the index hospital admission in a large cohort of consecutively treated alcoholic cirrhotic patients after a first variceal bleed. Methods. From January 1984 to August 2011, 448 alcoholic cirrhotic patients (349 men, 99 women; median age 50 years) with VB underwent endoscopic treatments (556 emergency, 249 elective) during the index hospital admission. Endoscopic control of initial bleeding, variceal rebleeding and survival after the first hospital admission were recorded. Results. Endoscopic intervention alone controlled VB in 394 patients (87.9%); 54 also required balloon tamponade. Within 24 hours 15 patients rebled; after 24 hours 61 (17%, n=76) rebled; and 93 (20.8%) died in hospital. No Child-Pugh (C-P) grade A patients died, while 16 grade B and 77 grade C patients died. Mortality increased exponentially as the C-P score increased, reaching 80% when the C-P score exceeded 13. Conclusion. Despite initial control of variceal haemorrhage, 1 in 6 patients (17%) rebled during the first hospital admission. Survival (79.2%) was influenced by the severity of liver failure, with most deaths occurring in C-P grade C patients

    Background: Fluoroscopy-guided endoscopic placement of nasojejunal tubes (NJT) for perioperative short- or medium-term enteral nutrition (EN) is potentially required for anatomical gastric feed intolerance. Methods: Indication for NJT and successful insertion rates was determined. NJT insertion costs were calculated and compared with central venous catheter (CVC) insertion. Duration of NJT patency in non-critical care surgical patients was determined in days in a local cohort. EN costs were calculated over a hypothetical 28-day period factoring in expected NJT replacements due to blockage and compared with parenteral nutrition (PN) via CVC, which included routine CVC changes every 10 days. Public and private sectors were compared. Results: One hundred and two (93.6%) NJTs were placed successfully, with gastric outlet obstruction the most frequent indication (40.4%) with a median 10 days’ (range 1–68 days, IQR 6–16.75 days) usage. Irrevocable blockage occurred in 33 tubes after a median 9 days (range 3–34 days; IQR 4.75–16 days). Calculated EN costs over 28 days, including NJT replacement every 9 days, reached US1676.12andPNcostswithCVCreplacementevery10days,US1 676.12 and PN costs with CVC replacement every 10 days, US3 461.35 (p < 0.001) in the public sector. In the private sector PN costs at 28 days were significantly higher (p < 0.001) at US5261.14comparedwithENUS5 261.14 compared with EN US3 780.71. The cost benefit of EN over PN is seen after three days in the public, and four days in the private sector. Conclusion: Exponential cost saving occurs with EN via NJT over time, even when factoring in the likelihood of NJT replacements

    Abstract Liver failure, whether arising directly from acute liver failure or from decompensated chronic liver disease is an increasing problem worldwide and results in many deaths. In the UK only 10% of individuals requiring a liver transplant receive one. Thus the need for alternative treatments is paramount. A BioArtificial Liver machine could temporarily replace the functions of the liver, buying time for the patient’s liver to repair and regenerate. We have designed, implemented and tested a clinical-scale BioArtificial Liver machine containing a biomass derived from a hepatoblastoma cell-line cultured as three dimensional organoids, using a fluidised bed bioreactor, together with single-use bioprocessing equipment, with complete control of nutrient provision with feedback BioXpert recipe processes, and yielding good phenotypic liver functions. The methodology has been designed to meet specifications for GMP production, required for manufacture of advanced therapy medicinal products (ATMPs). In a porcine model of severe liver failure, damage was assured in all animals by surgical ischaemia in pigs with human sized livers (1.2–1.6 kg liver weights). The BioArtificial liver (UCLBAL) improved important prognostic clinical liver-related parameters, eg, a significant improvement in coagulation, reduction in vasopressor requirements, improvement in blood pH and in parameters of intracranial pressure (ICP) and oxygenation

    © 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 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.

    © 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
