- 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.

The Association Between Beta-Blockade and Clinical Outcomes in the Context of Surgical and Traumatic Stress
- 2019

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Traumatic injury and major abdominal surgery are areas in general surgery associated with high rates of morbidity and mortality. The overall colorectal cancer surgery mortality rate is around 4%, with that for emergency surgery more than twice as high as for planned. Surgical morbidity varies between 25% and 45%. Around half of trauma patients develop low mood. In one quarter of patients this becomes permanent. Depression is known to impede physical rehabilitation and recovery. The onset of physiological stress, driven by adrenergic hyperactivity following traumatic and surgical injury is hypothesized to contribute to these adverse outcomes. Interest has therefore been sparked into blocking adrenergic receptor activation.Papers I and II investigated the role of beta-blocker therapy in preventing post-traumatic depression following severe traumatic brain injury (Paper I) and severe extracranial injury (Paper II). The Karolinska University Hospital Trauma Registry was used to identify patients admitted between 2007 and 2011. In Paper I (n = 545), patients on pre-injury beta-blocker therapy were matched to beta-blocker naïve patients with equivalent injury burden. Results revealed that beta-blocked patients exhibited a 60% reduced risk of needing antidepressant therapy within one year of trauma. In Paper II (n = 596), the lack of beta-blocker use before extracranial trauma was linked to a three-fold increase in the risk of antidepressant initiation.Papers III-V explored the role of pre-operative beta-blocker therapy in patients undergoing surgery for colorectal cancer between 2007 and 2016, identified using the nationwide Swedish Colorectal Cancer Registry. Paper III (n = 3,187) identified a 69% reduction in the risk of 30-day mortality in beta-blocked patients. Paper IV (n = 22,337) outlined long-term survival benefits for patients on beta-blocker therapy prior to undergoing elective surgery for colon cancer. Beta-blocked patients showed a risk reduction of 42% for 1-year all-cause mortality and 18% for 5-year cancerspecific mortality. Similarly, patients on beta-blocker therapy who underwent surgery for rectal cancer demonstrated improved survival up to one year after surgery with a risk reduction of 57% and a reduction in anastomotic failure and infectious complications in Paper V (n = 11,966).

- Background: Intracranial pressure (ICP) monitoring in traumatic brain injury (TBI) is common. Yet, its efficacy varies between studies, and the actual effect on the outcome is debated. This study investigates the association of ICP monitoring and clinical outcome in patients with an isolated severe blunt TBI.Patients and Methods: Patients were recruited from the American College of Surgeons-Trauma Quality Improvement Program database during 2014. Inclusion criteria were limited to adult patients (>= 18 years) who had a sustained isolated severe intracranial injury (Abbreviated Injury Scale [AIS] head of >= 3 and Glasgow Coma Scale [GCS] of <= 8) following blunt trauma to the head. Patients with AIS score >0 for any extracranial body area were excluded. Patients' demographics, injury characteristics, interventions, and outcomes were collected for analysis. Patients receiving ICP monitoring were matched in a 1:1 ratio with controls who were not ICP monitored using propensity score matching.Results: A total of 3289 patients met inclusion criteria. Of these, 601 (18.3%) were ICP monitored. After propensity score matching, 557 pairs were available for analysis with a mean age of 44 (standard deviation 18) years and 80.2% of them were male. Median GCS on admission was 4[3,7], and a third of patients required neurosurgical intervention. There were no statistical differences in any variables included in the analysis between the ICP-monitored group and their matched counterparts. ICP-monitored patients required significantly longer intensive care unit and hospital length of stay and had an increased mortality risk with odds ratio of 1.6 (95% confidence interval: 1.1-2.5, P = 0.038).Conclusion: ICP monitoring is associated with increased in-hospital mortality in patients with an isolated severe TBI. Further investigation into which patients may benefit from this intervention is required.

- 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.

- Introduction: The timing and optimal method for common bile duct (CBD) clearance and laparoscopic cholecystectomy remains controversial. Several different approaches are available in clinical practice. The current study presents the experience of two European hospitals of simultaneous laparoscopic cholecystectomy (LC) and intra-operative endoscopic retrograde cholangiopacreatography (IO-ERCP) done by surgeons.Methods: Retrospective analysis of all consecutive patients subjected to LC+IO-ERCP during their index admission between 4/2014 and 9/2016. Data accrued included patient demographics, laboratory markers, operation time (min) reported as mean (SD) and hospital length of stay (LOS) reported as median (lower quartile, upper quartile).Results: During the 29-month study, a total of 201 consecutive LC+IO-ERCPs were performed. The mean age of patients was 55 +/- 19years and 67% were female. The mean intervention time was 105 +/- 44min. The total LOS was 4 (3, 7) days and the post-operative LOS was 2 (1, 3)days. A total of 6 (3%) patients experienced post-interventional pancreatitis and two (1%) patients suffered a Strasberg type A bile leak. All patients were successfully discharged.Conclusion: Simultaneous LC+IO-ERCP is associated with few complications. Further studies investigating cost-benefit and patient satisfaction are warranted.
