    Mortality of emergency abdominal surgery in high-, middle- and low-income countries

    Background: Surgical mortality data are collected routinely in high-income countries, yet virtually no low- or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI). Methods: This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression. Results: Data were obtained for 10 745 patients from 357 centres in 58 countries; 6538 were from high-, 2889 from middle- and 1318 from low-HDI settings. The overall mortality rate was 1·6 per cent at 24 h (high 1·1 per cent, middle 1·9 per cent, low 3·4 per cent; P < 0·001), increasing to 5·4 per cent by 30 days (high 4·5 per cent, middle 6·0 per cent, low 8·6 per cent; P < 0·001). Of the 578 patients who died, 404 (69·9 per cent) did so between 24 h and 30 days following surgery (high 74·2 per cent, middle 68·8 per cent, low 60·5 per cent). After adjustment, 30-day mortality remained higher in middle-income (odds ratio (OR) 2·78, 95 per cent c.i. 1·84 to 4·20) and low-income (OR 2·97, 1·84 to 4·81) countries. Surgical safety checklist use was less frequent in low- and middle-income countries, but when used was associated with reduced mortality at 30 days. Conclusion: Mortality is three times higher in low- compared with high-HDI countries even when adjusted for prognostic factors. Patient safety factors may have an important role.

    Thoracic stent graft versus surgery for thoracic aneurysm

    No full text
    Thoracic aortic aneurysm (TAA) is an uncommon disease with an incidence of 10.4 per 100,000 inhabitants. It occurs mainly in older individuals and is evenly distributed among both sexes. There are no signs or symptoms indicative of the presence of the disease. Progressive but unpredictable enlargement of the dilated aorta is the natural course of the disease and can lead to rupture. Open chest surgical repair using prosthetic graft interposition has been a conventional treatment for TAAs. Despite improvements in surgical procedures perioperative complications remain significant. The alternative option of thoracic endovascular aneurysm repair (TEVAR) is considered a less invasive and potentially safer technique, with lower morbidity and mortality compared with conventional treatment. Evidence is needed to support the use of TEVAR for these patients, rather than open surgery. The aim of this review is to assess the efficacy of TEVAR versus conventional open surgery in patients with TAAs. For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched March 2013) and CENTRAL (2013, Issue 2). Randomised controlled trials in which patients with TAAs were randomly assigned to TEVAR or open surgical repair. Two review authors independently identified and evaluated potential trials for eligibility. Excluded studies were further checked by another author. We did not perform any statistical analyses as no randomised controlled trials were identified. We did not find any published or unpublished randomised controlled trials comparing TEVAR with conventional open surgical repair for the treatment of thoracic aortic aneurysms. Though stent grafting of the thoracic aorta is technically feasible and non-randomised studies suggest reduction of early outcomes such as paraplegia, mortality and hospital stay, high quality randomised controlled trials assessing all clinically relevant outcomes including open-conversion, aneurysm exclusion, endoleaks, and late mortality are needed

    Laparoscopic versus open surgery in small bowel obstruction

    BACKGROUND: Acute intestinal obstruction is one of the most common surgical emergencies. The small bowel obstruction (SBO) is the site of obstruction in most patients (76%) and adhesions are the most common etiology (65%). Laparoscopy in SBO has no clear role yet as it may have a therapeutic and diagnostic function. In some settings laparoscopic or laparoscopy-assisted surgery is considered feasible and convenient more than conventional surgery for SBO; however little is known if laparoscopic or laparoscopy-assisted surgery is more suitable with respect to open surgery for patients with SBO. OBJECTIVES: The aim of this systematic review is to assess whether laparoscopic or laparoscopy-assisted surgery is feasible and safe for acute SBO, and whether laparoscopic and laparoscopy-assisted surgery present advantages compared to open surgery in terms of short-term and long-term outcomes. SEARCH STRATEGY: We searched for published randomised and prospective controlled clinical trials without language restrictions using the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1950 onwards) and EMBASE (1980 onwards). SELECTION CRITERIA: Randomised controlled trials and non randomised controlled prospective trials evaluating laparoscopic and laparoscopy-assisted surgery versus traditional open surgery for acute SBO were considered. DATA COLLECTION AND ANALYSIS: We conducted the review according to the recommendations of The Cochrane Collaboration and the Cochrane Colorectal Group as well, using Review Manager 5 to conduct the review. MAIN RESULTS: No published or unpublished randomised controlled trials or prospective controlled clinical trials comparing laparoscopy with open surgery for patients with SBO were identified. AUTHORS' CONCLUSIONS: Although data from retrospective clinical controlled trials suggest that laparoscopy seems feasible and better in terms of hospital stay and mortality reduction, high quality randomised controlled trials assessing all clinically relevant outcomes including overall mortality, morbidity, hospital stay and conversion are needed
