  • The Relationship Between Severe Complications, Beta-Blocker Therapy and Long-Term Survival Following Emergency Surgery for Colon Cancer
  • 2019
  • Ingår i: World Journal of Surgery. - : Springer. - 0364-2313 .- 1432-2323. ; 43:10, s. 2527-2535
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Emergency surgery for colon cancer carries significant morbidity, and studies show more than doubled mortality when comparing elective to emergency surgery. The relationship between postoperative complications and survival has been outlined. Beta-blocker therapy has been linked to improved postoperative outcomes. This study aims to assess the impact of postoperative complications on long-term survival following emergency surgery for colon cancer and to determine whether beta-blockade can reduce complications.STUDY DESIGN: This cohort study utilized the prospective Swedish Colorectal Cancer Registry to identify adults undergoing emergency colon cancer surgery between 2011 and 2016. Prescription data for preoperative beta-blocker therapy were collected from the national drug registry. Cox regression was used to evaluate the effect of beta-blocker exposure and complications on 1-year mortality, and Poisson regression was used to evaluate beta-blocker exposure in patients with major complications.RESULTS: A total of 3139 patients were included with a mean age of 73.1 [12.4] of which 671 (21.4%) were prescribed beta-blockers prior to surgery. Major complications occurred in 375 (11.9%) patients. Those suffering major complications showed a threefold increase in 1-year mortality (adjusted HR = 3.29; 95% CI 2.75-3.94; p < 0.001). Beta-blocker use was linked to a 60% risk reduction in 1-year mortality (adjusted HR = 0.40; 95% CI 0.26-0.62; p < 0.001) but did not show a statistically significant association with reductions in major complications (adjusted IRR = 0.77; 95% CI 0.59-1.00; p = 0.055).CONCLUSION: The development of major complications after emergency colon cancer surgery is associated with increased mortality during one year after surgery. Beta-blocker therapy may protect against postoperative complications.

  • Guidelines for enhanced recovery after lung surgery : recommendations of the Enhanced Recovery After Surgery (ERAS®) Society and the European Society of Thoracic Surgeons (ESTS)
  • 2019
  • Ingår i: European Journal of Cardio-Thoracic Surgery. - : Springer. - 1010-7940 .- 1873-734X. ; 55:1, s. 91-115
  • Forskningsöversikt (refereegranskat)abstract
    • Enhanced recovery after surgery is well established in specialties such as colorectal surgery. It is achieved through the introduction of multiple evidence-based perioperative measures that aim to diminish postoperative organ dysfunction while facilitating recovery. This review aims to present consensus recommendations for the optimal perioperative management of patients undergoing thoracic surgery (principally lung resection). A systematic review of meta-analyses, randomized controlled trials, large non-randomized studies and reviews was conducted for each protocol element. Smaller prospective and retrospective cohort studies were considered only when higher-level evidence was unavailable. The quality of the evidence base was graded by the authors and used to form consensus recommendations for each topic. Development of these recommendations was endorsed by the Enhanced Recovery after Surgery Society and the European Society for Thoracic Surgery. Recommendations were developed for a total of 45 enhanced recovery items covering topics related to preadmission, admission, intraoperative care and postoperative care. Most are based on good-quality studies. In some instances, good-quality data were not available, and subsequent recommendations are generic or based on data extrapolated from other specialties. In other cases, no recommendation can currently be made because either equipoise exists or there is a lack of available evidence. Recommendations are based not only on the quality of the evidence but also on the balance between desirable and undesirable effects. Key recommendations include preoperative counselling, nutritional screening, smoking cessation, prehabilitation for high-risk patients, avoidance of fasting, carbohydrate loading, avoidance of preoperative sedatives, venous thromboembolism prophylaxis, prevention of hypothermia, short-acting anaesthetics to facilitate early emergence, regional anaesthesia, nausea and vomiting control, opioid-sparing analgesia, euvolemic fluid management, minimally invasive surgery, early chest drain removal, avoidance of urinary catheters and early mobilization after surgery. These guidelines outline recommendations for the perioperative management of patients undergoing lung surgery based on the best available evidence. As the recommendation grade for most of the elements is strong, the use of a systematic perioperative care pathway has the potential to improve outcomes after surgery.

  • Prognostic Value of P-POSSUM and Osteopenia for Predicting Mortality After Emergency Laparotomy in Geriatric Patients
  • 2019
  • Ingår i: Bulletin of emergency and trauma. - : Shiraz University of Medical Sciences. - 2322-2522 .- 2322-3960. ; 7:3, s. 223-231
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To evaluate the Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) in comparison with other risk factors for mortality including osteopenia as an indicator for frailty in geriatric patients subjected to emergency laparotomy.Methods: All geriatric patients (≥65 years) undergoing emergency laparotomy at a single university hospital between 1/2015 and 12/2016 were included in this cohort study. Demographics and outcomes were retrospectively collected from medical records. Association between prognostic markers and 30-day mortality was assessed using Poisson and backward stepwise regression models. Prognostic value was assessed using receiver operating characteristic (ROC) curves.Results: =0.004) while osteopenia was not. P-POSSUM had poor prognostic value for 30-day mortality with an area under the ROC curve (AUC) of 0.59. The prognostic value of P-POSSUM improved significantly when adjusting for patient covariates (AUC=0.83).Conclusion: P-POSSUM and osteopenia alone hardly predict 30-day mortality in geriatric patients following emergency laparotomy. P-POSSUM adjusted for other patient covariates improves the prediction.

  • Embracing change : the era for pediatric ERAS is here
  • 2019
  • Ingår i: Pediatric surgery international (Print). - : Springer. - 0179-0358 .- 1437-9813. ; 35:6, s. 631-634
  • Tidskriftsartikel (refereegranskat)abstract
    • The concept of Enhanced Recovery After Surgery (ERAS) has increasingly been embraced by our adult surgical colleagues, but has been slow to crossover to pediatric surgical subspecialties. ERAS® improves outcomes through multiple, incremental steps that act synergistically throughout the entire surgical journey. In practice, ERAS® is a strategy of perioperative management that is defined by strong implementation and ongoing adherence to a patient-focused, multidisciplinary, and multimodal approach. There are increasing numbers of surgical teams exploring ERAS® in children and there is mounting evidence that this approach may improve surgical care for children across the globe. The first World Congress in Pediatric ERAS® in 2018 has set the stage for a new era in pediatric surgical safety.

  • Optimal Perioperative Care in Major Head and Neck Cancer Surgery With Free Flap Reconstruction : A Consensus Review and Recommendations From the Enhanced Recovery After Surgery Society
  • 2017
  • Ingår i: JAMA Otolaryngology - Head and Neck Surgery. - Chicago, USA : American Medical Association. - 2168-6181 .- 2168-619X. ; 143:3, s. 292-303
  • Forskningsöversikt (refereegranskat)abstract
    • Importance: Head and neck cancers often require complex, labor-intensive surgeries, especially when free flap reconstruction is required. Enhanced recovery is important in this patient population but evidence-based protocols on perioperative care for this population are lacking.Objective: To provide a consensus-based protocol for optimal perioperative care of patients undergoing head and neck cancer surgery with free flap reconstruction.Evidence Review: Following endorsement by the Enhanced Recovery After Surgery (ERAS) Society to develop this protocol, a systematic review was conducted for each topic. The PubMed and Cochrane databases were initially searched to identify relevant publications on head and neck cancer surgery from 1965 through April 2015. Consistent key words for each topic included "head and neck surgery," "pharyngectomy," "laryngectomy," "laryngopharyngectomy," "neck dissection," "parotid lymphadenectomy," "thyroidectomy," "oral cavity resection," "glossectomy," and "head and neck." The final selection of literature included meta-analyses and systematic reviews as well as randomized controlled trials where available. In the absence of high-level data, case series and nonrandomized studies in head and neck cancer surgery patients or randomized controlled trials and systematic reviews in non-head and neck cancer surgery patients, were considered. An international panel of experts in major head and neck cancer surgery and enhanced recovery after surgery reviewed and assessed the literature for quality and developed recommendations for each topic based on the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. All recommendations were graded following a consensus discussion among the expert panel.Findings: The literature search, including a hand search of reference lists, identified 215 relevant publications that were considered to be the best evidence for the topic areas. A total of 17 topic areas were identified for inclusion in the protocol for the perioperative care of patients undergoing major head and neck cancer surgery with free flap reconstruction. Best practice includes several elements of perioperative care. Among these elements are the provision of preoperative carbohydrate treatment, pharmacologic thromboprophylaxis, perioperative antibiotics in clean-contaminated procedures, corticosteroid and antiemetic medications, short acting anxiolytics, goal-directed fluid management, opioid-sparing multimodal analgesia, frequent flap monitoring, early mobilization, and the avoidance of preoperative fasting.Conclusions and Relevance: The evidence base for specific perioperative care elements in head and neck cancer surgery is variable and in many cases information from different surgerical procedures form the basis for these recommendations. Clinical evaluation of these recommendations is a logical next step and further research in this patient population is warranted.

  • Bacterial translocation after non-lethal hemorrhage in the rat
  • 1993
  • Ingår i: Circulatory Shock. - : John Wiley & Sons. - 0092-6213. ; 41:1, s. 60-65
  • Tidskriftsartikel (refereegranskat)abstract
    • Translocation of enteric bacteria has been suggested to compromise patients in severe catabolic stress. Mechanisms for this route of infection are not known. In this study, ratswere subjected to hemorrhage without reinfusion during 60 min, total blood loss was 3.28 +/- 0.14 ml/100 g BW. Control groups consisted of sham-operated animals without bleeding, and rats not operated at all. The mean number of viable bacteria found in mesenteric lymph nodes (MLN) of bled animals was 168 +/- 45 colony forming units (c.f.u./MLN), significantly higher compared to sham operated (5 +/- 3 c.f.u./MLN) and not operated (0 +/- 0 c.f.u./MLN) controls (P < 0.01). Cultures from MLN were positive in 7/9 rats after bleeding, in 3/9 of sham operated, and in 0/6 of non-instrumented control animals. No positive blood cultures were isolated. Escherichia coli was the dominant species found in MLN. A biochemical fingerprinting method (the PhP system) was used to identify translocating strains of E. coli among strains found in cecum. The method was also used to compare translocating strains between different animals. Our findings reveal that bacteria translocate to MLN after hemorrhage. Some phenotypes of E. coli strains translocate more frequently than others, suggesting that they have properties facilitating translocation.

  • Preinjury β-blockade is protective in isolated severe traumatic brain injury
  • 2014
  • Ingår i: Journal of Trauma and Acute Care Surgery. - Philadelphia, USA : Lippincott Williams & Wilkins. - 2163-0755 .- 2163-0763. ; 76:3, s. 804-808
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The purpose of this study was to investigate the effect of preinjury β-blockade in patients experiencing isolated severe traumatic brain injury (TBI). We hypothesized that β-blockade before TBI is associated with improved survival.Methods: The trauma registry of an urban academic trauma center was queried to identify patients with an isolated severe TBI between January 2007 and December 2011. Isolated severe TBI was defined as an intracranial injury with an Abbreviated Injury Scale (AIS) score of 3 or greater excluding all extracranial injuries AIS score of 3 or greater. Patient demographics, clinical characteristics on admission, injury profile, Injury Severity Score (ISS), AIS score, in-hospital morbidity, and β-blocker exposure were abstracted for analysis. The primary outcome evaluated was in-hospital mortality stratified by preinjury β-blockade exposure.Results: Overall, a total of 662 patients met the study criteria. Of these, 25% (n = 159) were exposed to β-blockade before their traumatic insult. When comparing the demographics and injury characteristics between the groups, the sole difference was age, with the β-blocked group being older (69 [12] years vs. 63 [13] years, p < 0.001). β-blocked patients had a higher rate of infectious complications (30% vs. 19%, p = 0.04), with no difference in cardiac or pulmonary complications between the cohorts. Patients exposed to β-blockade versus no β-blockade experienced 13% and 22% mortality, respectively (p = 0.01). Stepwise logistic regression predicted the absence of β-blockade exposure as a risk factor for mortality (odds ratio, 2.7; 95% confidence interval, 1.5-4.8; p = 0.002). After adjustment for significant differences between the groups, patients not exposed to β-blockade experienced twofold increased risk of mortality (adjusted odds ratio, 2.2; 95% confidence interval, 1.3-3.7; p = 0.004).Conclusion: Preinjury β-blockade improves survival following isolated severe TBI. The role of prophylactic β-blockade and the timing of initiation of such therapy after TBI warrant further investigations.Level of evidence: Therapeutic study, level III; prognostic study, level II.

  • Effect of beta-blocker therapy on early mortality after emergency colonic cancer surgery
  • 2019
  • Ingår i: British Journal of Surgery. - : John Wiley & Sons. - 0007-1323 .- 1365-2168. ; 106:4, s. 477-483
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Emergency colorectal cancer surgery is associated with significant mortality. Induced adrenergic hyperactivity is thought to be an important contributor. Downregulating the effects of circulating catecholamines may reduce the risk of adverse outcomes. This study assessed whether regular preoperative beta-blockade reduced mortality after emergency colonic cancer surgery.METHODS: This cohort study used the prospectively collected Swedish Colorectal Cancer Registry to recruit all adult patients requiring emergency colonic cancer surgery between 2011 and 2016. Patients were subdivided into those receiving regular beta-blocker therapy before surgery and those who were not (control). Demographics and clinical outcomes were compared. Risk factors for 30-day mortality were evaluated using Poisson regression analysis.RESULTS: A total of 3187 patients were included, of whom 685 (21·5 per cent) used regular beta-blocker therapy before surgery. The overall 30-day mortality rate was significantly reduced in the beta-blocker group compared with controls: 3·1 (95 per cent c.i. 1·9 to 4·7) versus 8·6 (7·6 to 9·8) per cent respectively (P < 0·001). Beta-blocker therapy was the only modifiable protective factor identified in multivariable analysis of 30-day all-cause mortality (incidence rate ratio 0·31, 95 per cent c.i. 0·20 to 0·47; P < 0·001) and was associated with a significant reduction in death of cardiovascular, respiratory, sepsis and multiple organ failure origin.CONCLUSION: Preoperative beta-blocker therapy may be associated with a reduction in 30-day mortality following emergency colonic cancer surgery.

  • Effects of beta-blocker therapy on mortality after elective colon cancer surgery : a Swedish nationwide cohort study
  • 2020
  • Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 10:7
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Colon cancer surgery remains associated with substantial postoperative morbidity and mortality despite advances in surgical techniques and care. The trauma of surgery triggers adrenergic hyperactivation which drives adverse stress responses. We hypothesised that outcome benefits are gained by reducing the effects of hyperadrenergic activity with beta-blocker therapy in patients undergoing colon cancer surgery. This study aims to test this hypothesis.DESIGN: Retrospective cohort study.SETTING AND PARTICIPANTS: This is a nationwide study which includes all adult patients undergoing elective colon cancer surgery in Sweden over 10 years. Patient data were collected from the Swedish Colorectal Cancer Registry. The national drugs registry was used to obtain information about beta-blocker use. Patients were subdivided into exposed and unexposed groups. The association between beta-blockade, short-term and long-term mortality was evaluated using Poisson regression, Kaplan-Meier curves and Cox regression.PRIMARY AND SECONDARY OUTCOMES: Primary outcome of interest was 1-year all-cause mortality. Secondary outcomes included 90-day all-cause and 5-year cancer-specific mortality.RESULTS: The study included 22 337 patients of whom 36.1% were prescribed preoperative beta-blockers. Survival was higher in patients on beta-blockers up to 1 year after surgery despite this group being significantly older and of higher comorbidity. Regression analysis demonstrated significant reductions in 90-day deaths (IRR 0.29, 95% CI 0.24 to 0.35, p<0.001) and a 43% risk reduction in 1-year all-cause mortality (adjusted HR 0.57, 95% CI 0.52 to 0.63, p<0.001) in beta-blocked patients. In addition, cancer-specific mortality up to 5 years after surgery was reduced in beta-blocked patients (adjusted HR 0.80, 95% CI 0.73 to 0.88, p<0.001).CONCLUSION: Preoperative beta-blockade is associated with significant reductions in postoperative short-term and long-term mortality following elective colon cancer surgery. Its potential prophylactic effect warrants further interventional studies to determine whether beta-blockade can be used as a way of improving outcomes for this patient group.

  • β-Blockade in Rectal Cancer Surgery : A Simple Measure of Improving Outcomes
  • 2020
  • Ingår i: Annals of Surgery. - : Lippincott Williams & Wilkins. - 0003-4932 .- 1528-1140. ; 271:1, s. 140-146
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To ascertain whether regular β-blocker exposure can improve short- and long-term outcomes after rectal cancer surgery.BACKGROUND: Surgery for rectal cancer is associated with substantial morbidity and mortality. There is increasing evidence to suggest that there is a survival benefit in patients exposed to β-blockers undergoing non-cardiac surgery. Studies investigating the effects on outcomes in patients subjected to surgery for rectal cancer are lacking.METHODS: All adult patients undergoing elective abdominal resection for rectal cancer over a 10-year period were recruited from the prospectively collected Swedish Colorectal Cancer Registry. Patients were subdivided according to preoperative β-blocker exposure status. Outcomes of interest were 30-day complications, 30-day cause-specific mortality, and 1-year all-cause mortality. The association between β-blocker use and outcomes were analyzed using Poisson regression model with robust standard errors for 30-day complications and cause-specific mortality. One-year survival was assessed using Cox proportional hazards regression model.RESULTS: A total of 11,966 patients were included in the current study, of whom 3513 (29.36%) were exposed to regular preoperative β-blockers. A significant decrease in 30-day mortality was detected (incidence rate ratio = 0.06, 95% confidence interval: 0.03-0.13, P < 0.001). Deaths of cardiovascular nature, respiratory origin, sepsis, and multiorgan failure were significantly lower in β-blocker users, as were the incidences in postoperative infection and anastomotic failure. The β-blocker positive group had significantly better survival up to 1 year postoperatively with a risk reduction of 57% (hazard ratio = 0.43, 95% confidence interval: 0.37-0.52, P < 0.001).CONCLUSIONS: Preoperative β-blocker use is strongly associated with improved survival and morbidity after abdominal resection for rectal cancer.
