Introduction: Radical surgery combined with chemotherapy is the only potential curative treatment of patients with advanced epithelial ovarian cancer (EOC). However, 43% of older Danish patients with EOC are not referred to surgery due to frailty, age, or fear of complications. Comprehensive geriatric assessment (CGA) has demonstrated ability to reduce frailty in older patients, but there is a knowledge gap regarding its effect before or during treatment in older adults with EOC. This protocol presents a randomized controlled trial (RCT), which evaluates the effect of CGA-based interventions including individualized physical exercise therapy in older adults with EOC during neoadjuvant chemotherapy (NACT)., Materials and Methods: This RCT will include patients aged ≥70 years with primary EOC referred to NACT. Patients will be randomized 1:1 to intervention or standard of care, along with neoadjuvant antineoplastic treatment. Stratification for performance status and center of inclusion will be performed. In the intervention arm, a geriatrician will perform CGA and corresponding geriatric interventions and patients will undergo an individualized home-based exercise program managed by a physiotherapist. All patients will be evaluated with Geriatric-8, modified Geriatric-8, clinical frailty scale, and physical tests at randomization. Predictive values (positive/negative) will be evaluated for CGA detected impairments. The primary endpoint is the proportion of patients referred to interval debulking surgery (IDS). Secondary endpoints include the proportion who complete oncological treatment, improvements in physical tests, quality of life measured by European Organization for Research and Treatment of Cancer-Quality of Life questionnaires at inclusion, after three cycles of chemotherapy, and at end of chemotherapy treatment. Furthermore, the association between results of geriatric screening tests, CGA, and physical tests with complication rate and progression free survival will be examined. The primary outcome will be analyzed with logistic regression in the intention-to-treat population. Power calculations reveal the need to enroll 216 patients., Discussion: The present study examines whether CGA-based interventions including individualized physical exercise can increase the referral rate for potential curative IDS in older patients with EOC. If successful, this will result in more patients undergoing surgery and completing chemotherapy, preventing complications, and ultimately improving quality of life and survival. The study setup may establish the basis for direct clinical implementation if proven effective., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024 Elsevier Ltd.

Background: Acute Kidney Injury (AKI) is a frequent and serious postoperative complication in trauma or critically ill patients in the intensive care unit. We aimed to estimate the risk of AKI following major emergency abdominal surgery and the association between AKI and 90-day postoperative mortality., Methods: In this retrospective cohort study, we included patients undergoing major emergency abdominal surgery at the Department of Surgery, Zealand University Hospital, Denmark, from 2010 to 2016. The primary outcome was the occurrence of AKI within postoperative day seven (POD7). AKI was defined according to the Kidney Disease: Improving Global Outcomes (KDIGO)-criteria. The risk of AKI was analysed with a multivariable logistic regression. The association between AKI and 90-day mortality was analysed with a multivariable survival analysis., Results: In the cohort, 122 out of 703 (17.4%) surgical patients had AKI within POD7. Of these, 82 (67.2%) had AKI stage 1, 26 (21.3%) had AKI stage 2, and 14 (11.5%) had AKI stage 3. Fifty-eight percent of the patients who developed postoperative AKI did so within the first 24 h of surgery. Ninety-day mortality was significantly higher in patients with AKI compared with patients without AKI (41/122 (33.6%) versus 40/581 (6.9%), adjusted hazard ratio 4.45 (95% confidence interval 2.69-7.39, P < 0.0001)), and rose with increasing KDIGO stage. Pre-existing hypertension and intraoperative peritoneal contamination were independently associated with the risk of AKI., Conclusions: The risk of AKI is high after major emergency abdominal surgery and is independently associated with the risk of death within 90 days of surgery., (© 2022.

Purpose: Patients undergoing major emergency abdominal surgery have a high mortality rate. Preoperative risk prediction tools of in-hospital mortality could assist clinical identification of patients at increased risk and thereby aid clinical decision-making and postoperative pathways. The aim of this study was to validate the preoperative score to predict mortality (POSPOM) in a population of patients undergoing major emergency abdominal surgery., Methods: POSPOM was investigated in a retrospectively collected cohort of patients undergoing major emergency abdominal surgery at a Danish University Hospital from 2010 to 2016. Predicted in-hospital mortality by POSPOM was compared to observed in-hospital mortality. Calibration was assessed by Hosmer-Lemeshow goodness-of-fit and calibration plot. Discrimination was assessed by area under the receiver operating characteristic curve and accuracy was assessed with Brier score., Results: The study included 979 patients (513 females) with a median age of 64 (IQR 55-77) years. The majority of patients underwent open surgery (94.5%). The observed in-hospital mortality rate was 10.9%. The estimated mean in-hospital mortality rate by POSPOM was 6.7%. POSPOM showed a good discrimination [AUC 0.82 (95% CI 0.78-0.85)] and an excellent accuracy [Brier score 0.09 (95% CI 0.07-0.10)]. However, a poor calibration was found (p < 0.01) as POSPOM underestimated in-hospital mortality., Conclusions: POSPOM is not an ideal prediction model for in-hospital mortality in patients undergoing major emergency abdominal surgery due a poor calibration., (© 2019.

Background: Optimal recovery can be defined as the adequate in-hospital length of stay with minimal postoperative complications and readmissions. The quality of recovery beyond the immediate postoperative period after major emergency abdominal surgery is yet to be fully described. We hypothesized that long-term measures of overall recovery were affected after surgery. The study aimed to investigate patient-focused recovery-related parameters 1 year after major emergency abdominal surgery., Method: This is a prospective study including patients undergoing major emergency abdominal surgery at a Danish secondary referral center. Three questionnaires were answered regarding the recovery following the procedure; Activities Assessment Scale (AAS); Quality of Recovery-15 (QoR-15), and Self-complete Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS). All questionnaires were answered at postoperative days (PODs) 14, 30, 90, and 365., Results: Eighty-two patients were included, and 68 were available for follow-up until 1 year after surgery. The response rates differed between the follow-up time points, with a response rate of 85% (n = 59) at POD30 and 50% (n = 36) at POD365. A decrease in the level of physical function following surgery was observed in 60% of the patients at POD14, which improved to 36% at POD365. Twenty-four patients (48%) reported postoperative pain at POD14, which declined to 9 (26%) at POD365. The maximum overall recovery was reached at POD30, which remained stable throughout the study period., Conclusion: One in three patients reported physical functional impairment, and one in four patients reported pain 1 year after their surgical procedure., (© 2021 The Acta Anaesthesiologica Scandinavica Foundation.

INTRODUCTION Major emergency abdominal surgery results in a high risk of morbidity and mortality. Preoperative neutrophil-to-lymphocyte ratio (NLR) has been proposed as a predictor of post-operative outcomes in elective surgery. The aim of the present study was to examine whether preoperative NLR was associated with post-operative morbidity and mortality after major emergency abdominal surgery. METHODS We conducted a retrospective cohort study of patients undergoing major emergency abdominal surgery in two university hospitals in Denmark between 2010 and 2016. Associations between preoperative NLR and 30-day post-operative complications and mortality were established through multivariate logistic regression and receiver-operating characteristics (ROC) analysis. RESULTS A total of 570 patients were included in the study. The overall 30-day mortality was 9.3% and 59.3% had post-operative complications. The median preoperative NLR was 8.6 (interquartile range: 4.8-14.7). Although NLR was higher in the group of patients who had complications or died after surgery, a multivariate analysis showed that the NLR was not associated with 30-day post-operative complications (odds ratio (OR) = 1.01 (95% confidence interval (CI): 0.99-1.02); p = 0.424) or mortality (OR = 0.99 (95% CI: 0.97-1.02); p = 0.57). The ROC analysis showed an area under the curve of 0.55 and 0.60 for 30-day post-operative complications and mortality, respectively. CONCLUSIONS Preoperative NLR was not associated with 30-day post-operative complications and mortality in patients undergoing major emergency abdominal surgery.  FUNDING none.

Purpose: The patient-perceived barriers towards an optimized short-term recovery after major emergency abdominal surgery are unknown. The purpose was to investigate which patient-perceived barriers dominated concerning nutrition, mobilization, and early discharge after major emergency abdominal surgery., Methods: An explorative study, which focused on patient-perceived barriers for early discharge, mobilization, and nutrition, was performed within an enhanced recovery perioperative setting in major emergency abdominal surgery. Patients were asked daily from postoperative day (POD) 1 to POD 7 of their self-perceived barriers towards getting fully mobilization and resuming normal oral intake. From POD 3 to POD 7, patients were asked regarding self-perceived barriers towards early discharge., Results: A total of 101 patients that underwent major emergency abdominal surgery were included for final analysis from March 2017 to August 2017. The main patient self-perceived barrier towards sufficient nutrition was dominated by food aversion (including loss of appetite). The main patient self-perceived barrier towards sufficient mobilization throughout the study period was fatigue. The patient self-perceived barriers towards early discharge were more diffuse and lacked a dominant variable throughout the study period; however, fatigue was the most pronounced barrier throughout the study period. The leading initial variables were postoperative ileus, insufficient nutrition, and epidural catheter. The leading later variables besides fatigue included awaiting normalization of biochemistry values, pain, and the perception of insufficient oral intake., Conclusions: The major patient-perceived factors that limited postoperative recovery after major emergency abdominal surgery included food aversion regarding normalization of oral intake and fatigue regarding mobilization and early discharge.

Background: Major emergency abdominal surgery results in high morbidity and mortality. We aimed to describe patient-reported quality of recovery after major emergency abdominal surgery., Methods: A prospective observational cohort study of patients undergoing major emergency abdominal surgery at a University Hospital was conducted in the period between November 2016 and February 2017. Patients were interviewed using the 15-item questionnaire Quality of Recovery (QoR-15) six times over the first 30 postoperative days. Patients' maximum score of QoR-15 ranging from 0-150 were divided into four groups depending on recovery status going from poor (score of 0-89), moderate (score of 90-121), good (score of 122-135) to excellent (score of 136-150) recovery., Results: A total of 37 patients were included in the trial. At postoperative day (POD) 1 the recovery status of the patients was mainly poor to moderate (poor N.=8 [22%], moderate N.=23 [62%], good N.=4 [11%] and excellent N.=2 [5%]). Sixteen (55%) of the patients reported a poor or moderate recovery within the first 7 days after surgery, which advanced to good or excellent recovery (N.=19 [68%]) from POD 14. The patients were not fully recovered at POD 30 (N.=18 [62%] had an excellent recovery)., Conclusions: Recovery measured by QoR-15 is substantially affected after major emergency abdominal surgery even after 14- and 30 days postoperatively. The patients were poor or only moderately recovered within the first seven postoperative days and only 62% of the patients were fully recovered at postoperative day 30.

Background: Preoperative endothelial dysfunction is a predictor of myocardial injury and major adverse cardiac events. Non-cardiac surgery is known to induce acute endothelial changes. The aim of this explorative cohort study was to assess the extent of systemic endothelial dysfunction after major emergency abdominal surgery and the potential association with postoperative myocardial injury., Methods: Patients undergoing major emergency abdominal surgery were included in this prospective cohort study. The primary outcome was the change in endothelial function expressed as the reactive hyperemia index from 4-24 h after surgery until postoperative day 3-5. The reactive hyperemia index was assessed by non-invasive digital pulse tonometry. Secondary outcomes included changes in biomarkers of nitric oxide metabolism and bioavailability. All assessments were performed at the two separate time points in the postoperative period. Clinical outcomes included myocardial injury within the third postoperative day and major adverse cardiovascular events within 30 days of surgery., Results: Between October 2016 and June 2017, 83 patients were included. The first assessment of the endothelial function, 4-24 h, was performed 15.8 (SD 6.9) hours after surgery and the second assessment, postoperative day 3-5, was performed 83.7 (SD 19.8) hours after surgery. The reactive hyperemia index was suppressed early after surgery and did not increase significantly; 1.64 (95% CI 1.52-177) at 4-24 h after surgery vs. 1.75 (95% CI 1.63-1.89) at postoperative day 3-5, p = 0.34. The L-arginine/ADMA ratio, expressing the nitric oxide production, was reduced in the perioperative period and correlated significantly with the reactive hyperemia index. A total of 16 patients (19.3%) had a major adverse cardiovascular event, of which 11 patients (13.3%) had myocardial injury. The L-arginine/ADMA ratio was significantly decreased at 4-24 h after surgery in patients suffering myocardial injury., Conclusion: This explorative pathophysiological study showed that acute systemic endothelial dysfunction was present early after major emergency abdominal surgery and remained unchanged until day 3-5 after the procedure. Early postoperative disturbances in the nitric oxide bioavailability might add to the pathogenesis of myocardial injury. This pathophysiological link should be confirmed in larger studies., Trial Registration: clinicaltrials.gov no. NCT03010969.

Background: Patients undergoing major open emergency abdominal surgery experience high morbidity and mortality rates and often have sepsis at admission. The purpose of this study was to evaluate the association between antibiotic timing and in-hospital outcomes such as complications, need for reoperation, length of stay, and 30-day mortality., Methods: This retrospective observational cohort study was conducted between January 2010 and December 2015 including patients that were triaged through the emergency department for subsequent major open abdominal surgery. All relevant perioperative data were extracted from medical records. The outcomes of interest were development of in-hospital postoperative complications, reoperations, length of stay, and 30-day mortality, all in association with antibiotic timing, categorized according to 0-6, 6-12, or > 12 h from triage. Multivariate logistic regression was performed to evaluate adjusted outcomes associated with antibiotic timing., Results: A total of 408 patients were included, of whom 107 (26.2%) underwent at least one reoperation and 55.4% had at least one postoperative complication. These complications consisted of 26% surgical complications and 74% medical complications. Of the surgical complications, 73% were Clavien-Dindo ≥ 3. The median length of stay was 9 days and the overall 30-day mortality was 17.9%. The data showed that the development of complications, need for reoperation, 30-day mortality, and the length of stay were significantly correlated to delayed antibiotic administration of more than 12 h from admission., Conclusions: Antibiotic administration more than 12 h from triage was associated with a significantly increased risk of postoperative complications, need for reoperation, 30-day mortality, and a prolonged length of stay, when compared to patients that received antibiotic treatment 0-6 h and 6-12 h after triage. Our data suggest that prophylactic antibiotics should be administered to all patients undergoing major open emergency abdominal surgery; however, the dose and duration cannot be concluded on the basis of our data and should be further examined.

Background: ABO dependent variation in von Willebrand factor (vWF) and factor VIII have an impact on hemostasis. Several contradictory studies have investigated the influence of ABO blood type in surgical hemorrhage. Emergency surgery is associated with an increased risk of perioperative hemorrhage leading to inferior clinical outcomes. The aim of this study was to investigate if patients with blood type O received more transfusions with blood components compared with non-O patients after major emergency abdominal surgery., Study Design and Methods: This retrospective observational study combined perioperative data including hemoglobin with transfusion data in patients undergoing emergency surgery at a university hospital between January 2010 and October 2016. The primary outcome was postoperative transfusion stratified into early transfusion, within 24 hours after surgery, and late transfusion from 24 hours to 7 days (POD7) after surgery., Results: A total of 869 patients were included, 363 patients with blood type O (42.0%) and 501 (58.0%) with blood type non-O. We found no difference in the need for transfusion with 42 (11.6%) patients with blood type O and 66 (13.2%) patients with blood type non-O receiving early transfusion and 39 (13.4%) and 48 (11.9%) of O and non-O patients, respectively, receiving late transfusion. Multivariate logistic regression analysis showed an adjusted OR of 0.915 (95% CI 0.569-1.471) for early transfusion and an adjusted OR of 1.307 (95% CI 0.788-2.169) for late transfusion in patients with blood type O. Likewise, no difference was seen with respect to the change in hemoglobin levels before and after surgery as well as transfused volume., Conclusion: We did not find an association between transfusion or perioperative changes in hemoglobin with respect to blood type ABO., (© 2018 AABB.)

Little is known about patient-reported outcomes after major emergency abdominal surgery. Studies on patients undergoing major elective abdominal surgery and patients in the intensive care unit report significant challenges with chronic pain, functional impairment, quality of life, depression and post-traumatic stress disorder (PTSD). Approximately one out of three patients experience chronic pain and functional impairment after major emergency abdominal surgery. The magnitude of depression and PTSD after major emergency abdominal surgery have not been studied before.
