Abstract Introduction This study aimed to determine whether COVID-19 free surgical pathways were associated with lower postoperative pulmonary complication rates compared to hospitals with no defined pathway. Method This international multi-centre cohort study included patients undergoing elective surgery for 10 solid cancer types, without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until 19 April 2020. At the time of surgery, hospitals were defined as having a COVID-19 free surgical pathway (complete segregation of the operating theatre, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with COVID-19 patients). The primary outcome was 30-day postoperative pulmonary complications. Results Of 9171 patients from 447 hospitals in 55 countries, 2481 were operated in COVID-19 free surgical pathways. After adjustment, pulmonary complication rates were lower with COVID-19 free surgical pathways (2.2% versus 4.9%, OR: 0.62 [0.44-0.86]). This was consistent in sensitivity analyses and a propensity-score matched model. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19 free surgical pathways (2.1% versus 3.6%; OR 0.53 [0.36-0.76]). Conclusions Within available resources, dedicated COVID-19 free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks.

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks.

Abstract Background The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery is poorly understood. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality. The secondary outcome measure was pulmonary complications (pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation). Findings This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p < 0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p < 0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p < 0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p = 0·046), emergency versus elective surgery (1·67 [1·06–2·63], p = 0·026), and major versus minor surgery (1·52 [1·01–2·31], p = 0·047). Interpretation Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than normal practice, particularly in men aged 70 years and older.

Abstract Background Malnutrition is a state linked to worse postoperative outcomes, and cancer patients are particularly vulnerable due to cachexia. We aimed to explore the effect of malnutrition on 30-day mortality following gastric and colorectal cancer surgery. Method GlobalSurg3 was multicentre international cohort study which collected data from consecutive patients undergoing emergency or elective surgery for gastric and colorectal cancer. Malnutrition was defined using the Global Leadership Initiative on Malnutrition (GLIM) criteria. Multilevel variable regression approaches determined the relationship between malnutrition and early postoperative outcomes. Results 6438 patients were included in the final analysis (1184 gastric cancer; 5254 colorectal cancer). Severe malnutrition was common across all income-strata, affecting 1 in 4 patients overall, with a higher burden in low and lower-middle income countries (64%). In patients undergoing elective surgery (n = 5709), severe malnutrition was independently associated with increased mortality (aOR = 1.62 (1.07-2.48, P = 0.024) after accounting for patient factors, disease stage and country effects. Conclusions Severe malnutrition represents a high global burden in cancer surgery, particularly within lower income settings. Malnutrition is an independent risk-factor for 30-day mortality following elective surgery for gastric and colorectal cancer, suggesting perioperative nutritional interventions may improve outcomes after cancer surgery.

Background: Postoperative pulmonary complications (PPC) are one of the commonest complications following gastrointestinal surgery. They lead to increase in morbidity and mortality. Lactate dehydrogenase (LDH) is an enzyme present in essentially all major organ systems. Studies have shown measurement of its activity levels and its isoenzyme pattern may provide additional information about lung and pulmonary endothelial cell injury. The objectives of the present study were to study the levels of serum LDH in patients with and without post-operative pulmonary complications following emergency abdominal surgery.Methods: The study was designed as an observational study. All patients ≥18 years of age undergoing gastrointestinal surgery, excluding those with prior lung pathology were included in the study. The demographic parameters, clinical parameters and laboratory parameters along with details of pulmonary complications were recorded. Serum LDH level were assessed on admission. Levels of serum LDH were compared between patients with and without post-operative pulmonary infections and were assessed for significance.Results: Incidence of PPC was 28% in our study. There was significant difference in the mean age in the group with and without PPC (p=<0.001). Smoking habit, serum albumin total protein and upper abdomen incision surgery were associated with increased incidence of PPC. Pleural effusion was the commonest PPC seen in patients. Serum LDH was not significantly associated with the incidence of PPC.Conclusions: Pre-operative serum LDH level is not a predictive factor for occurrence of postoperative pulmonary complication. Age, smoking, total protein, serum albumin, upper abdomen incision were found to associated with increased risk of PPCs.

Abstract Background Many authors have investigated the possible adverse effects among patients who underwent elective surgery on Friday when compared with patients operated earlier in the week. Nonetheless, the weekday effect is still a matter of debate. This study aimed at investigating the postoperative morbidity rates after lung cancer surgery and their relationship with the weekday the surgery took place. Materials and Methods We retrospectively reviewed the clinical records of patients who underwent elective thoracotomic lobectomies for lung cancer. Categorical data were analyzed using the chi-square test or Fisher's exact test. Association between predictors and binary outcomes while considering the weekday stratification was determined with Cochran–Mantel–Haenszel statistics. To characterize the typical Friday patient, a multiple logistic regression analysis was performed. Results A total of 817 patients (2015–2019) were identified. Complication rates divided by day of surgery were 164 (20.07%) for patients operated on Mondays, 182 (22.27%) on Tuesdays, 205 (25.09%) on Wednesdays, 172 (21.05%) on Thursdays, and 94 (11.51%) on Fridays. Crude morbidity rates by weekday were Monday 21.53%, Tuesday 20.51%, Wednesday 27.70%, Thursday 20.0%, and Friday 10.26%. No overall association between day of surgery and overall morbidity was found (ρ = 0.095). Median hospital length of stay was 5 days (range: 2–45 days), and there were no statistically significant differences between days. The Cochran–Mantel–Haenszel statistics showed no association between morbidity and the weekday. Conclusion In patients undergoing elective lobectomies for lung cancer, the weekday of surgery was not statistically significantly associated with an increase in the risk of postoperative morbidity.

Objective: To investigate the effects of rehabilitation either before or after operation for lung cancer on postoperative pulmonary complications and the length of hospital stay. Data sources: MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL Plus, SPORTDiscus, PsycInfo and Embase were searched from inception until June 2021. Review methods: Inclusion criteria were patients scheduled to undergo or had undergone operation for lung cancer, randomised controlled trials comparing rehabilitative interventions initiated before hospital discharge to usual care control. Two reviewers independently assessed eligibility, extracted data and risks of bias. Pooled odds ratios (ORs) or standardised mean differences (SMDs) with 95% Confidence Intervals (CI) were estimated using random-effects meta-analyses. Results: Twenty-three studies were included (12 preoperative, 10 postoperative and 1 perioperative), with 2068 participants. The pooled postoperative pulmonary complication risk and length of hospital stay were reduced after preoperative interventions (OR = 0.32; 95% CI = 0.22, 0.47; I2 = 0.0% and SMD = −1.68 days, 95% CI = −2.23, −1.13; I2 = 77.8%, respectively). Interventions delivered during the immediate postoperative period did not have any significant effects on either postoperative pulmonary complication or length of hospital stay (OR = 0.85; 95% CI = 0.56, 1.29; I2 = 0.0% and SMD = −0.23 days, 95% CI = −1.08, 0.63; I2 = 64.6%, respectively). Meta-regression showed an association between a higher number of supervised sessions and shorter hospital length of stay in preoperative studies (β = −0.17, 95% CI = −0.29, −0.05). Conclusion: Preoperative rehabilitation is effective in reducing postoperative pulmonary complications and length of hospital stay associated with lung cancer surgery. Short-term postoperative rehabilitation in inpatient settings is probably ineffective.

110 Background: Although 3D conformal radiation therapy (3D-CRT) is currently the de facto standard for the treatment of esophageal cancers, technologies such as Intensity Modulated Radiation Therapy (IMRT) or Proton Beam Therapy (PBT) are increasingly being used, but the evidence for the clinical benefits of these technologies are lacking. We hypothesized that radiation technology influences perioperative complications in esophageal cancer patients treated with neoadjuvant chemoradiation. Methods: We evaluated 423 patients (3D-CRT (n=208, 1998-2008), IMRT (n=165, 2004-2011), and PBT (n=50, 2006-2011)) treated with surgical resection after chemoradiation from 1998-2011 at M. D. Anderson Cancer Center. Postoperative complications (Pulmonary, GI, cardiac, wound healing) were recorded up to 30 days postoperatively. Kruskal-Wallis tests and Chi-square or Fisher’s exact tests assessed associations between continuous and categorical variables and the radiation technology, respectively. Logistic regression model tested the association between treatment technologies and complications adjusting for other significant patient characteristics. Results: While radiation modality was not significantly associated with postoperative GI (leak, ileus, fistula), cardiac (MI, AF, CHF), and wound complications, there was a significant reduction in postoperative pulmonary complications (ARDS, pleural effusion, respiratory insufficiency, pneumonia) for IMRT compared to 3D-CRT (OR 0.46, 95%CI 0.25, 0.83) and PBT compared to 3D-CRT (OR 0.26, 95%CI 0.09, 0.70), but not when IMRT was compared to PBT (OR 1.74, 95%CI 0.66, 4.61) after adjusting for preRT DLCO level. The median length of hospital stay was also significantly different between treatment modalities (12, 10, and 8 days for 3D-CRT, IMRT, and PBT, respectively, p<0.0001). There was no significant association between treatment year with pulmonary complication rates. Conclusions: Radiation technologies such as IMRT and PBT reduced postoperative pulmonary complication rates compared to 3D-CRT in esophageal cancer patients. This result needs to be confirmed in larger prospective studies.

IntroductionThis study reports the 30-day mortality, SARS-CoV-2 complication rate and SARS-CoV-2-related hospital processes at the peak of the first wave of the pandemic in the UK.MethodsThis national, multicentre, cohort study at 74 centres in the UK included all patients undergoing any surgery below the elbow at the peak of the UK pandemic. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The secondary outcomes were SARS-CoV-2 complication rates and overall complication rates. A clinician survey relating to SARS-CoV-2 safety processes was carried out for each participating centre.ResultsThis analysis includes 1093 patients who underwent upper limb surgery from the 1 to 14 April 2020 inclusively. The overall 30-day mortality was 0.09% (1 pre-existing SARS-CoV-2 pneumonia) and the mortality of day case surgery was zero. Most centres (96%) screened patients for symptoms prior to admission, only 22% routinely tested for SARS-CoV-2 prior to admission. The SARS-CoV-2 complication rate was 0.18% (2 pneumonias) and the overall complication rate was 6.6% (72 patients). Both SARS-CoV-2-related complications occurred in patients who had been hospitalised for a prolonged period before their surgery and a total of 19 patients (1.7%) were SARS-CoV-2 positive.ConclusionsThe SARS-CoV-2-related complication rate for upper limb surgery even at the peak of the UK pandemic was low at 0.18% and the mortality was zero for patients admitted on the day of surgery. Urgent surgery should not be delayed pending the results of SARS-CoV-2 testing. Routine SARS-CoV-2 testing for day case upper limb surgery not requiring general anaesthesia may be excessive and have unintended negative impacts.

Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.
