Critical assessment of preoperative and operative risk factors for complications after iterative peritonectomy procedures

UNSTRUCTURED Older patients account for a significant proportion of patients undergoing colorectal cancer surgery, and are vulnerable to a number of pre-operative risk factors that are not often present in younger patients. Three pre-operative risk factors more prevalent in the elderly are frailty, sarcopenia, and malnutrition. Whilst each of these has been studied in isolation, there is little information on the interplay between them in older surgical patients. One particular area of increasing interest is the use of urine metabolomics for objective evaluation of dietary profiles and malnutrition. Herein we describe the design, cohort, and standard operating procedures of a planned prospective study of older surgical patients undergoing colorectal cancer resection across multiple institutions in the United Kingdom. These procedures include serial frailty evaluations (Clinical Frailty Scale and Groningen Frailty Indicator), functional assessments (with hand grip strength and 4-metre walk test), muscle mass evaluations using computerized tomography morphometric analysis and evaluation of nutritional status using analysis of urinary dietary biomarkers. As these are all areas of common derangement in the elderly surgical population, prospectively studying them in concert will allow for analysis of their interplay as well as the development of predictive models for those at risk for commonly tracked surgical complications and outcomes.

A total correction is a preferred treatment for Tetralogy of Fallot patients in every part of the world. However, the mortality in developing countries was as high as 6.9% to 15.3%. This was a retrospective analytic study that analyzed pre and post-operative risk factors that affected mortality on TOF patients that were performed total correction in Indonesia. A total of 47 TOF patients that were performed total correction from January 2016 to September 2019 were enrolled in this study based on the inclusion criteria. Preoperative and post-operative data were obtained from medical records. In this research, the majority of mortality was found in male patients (39.3%), while the female’s rate was lower (36.8%). Overall mortality was 38.3% and one operative death was found. The average age of patients was 84.12 months (12-210 months), whereas the average height (85.56 ± 36.17cm vs. 112.93 ± 21.73) and weight (17.22kg vs. 28.21kg) were lower for mortality patients. Some significant preoperative variables were identified as mortality risk factors such as: age below 60 months (p=0.047), smaller weight and height (p=0.008; p=0.002), abnormal hematocrit (p=0.002), and oxygen saturation below 75% (p=0.018). Significant post-operative risk factors included: temperature above 38.5⁰C (p=0.000), and ventilator time of more than 48 hours (p=0.033). In conclusion, the mortality of TOF patients undergoing a total correction in developing countries was quite high. It was associated with some risk factors, such as younger age, lower weight and height, low oxygen saturation, post-operative fever, and prolonged ventilator time.

Background: Regular exercise is a known primary and secondary defense against cardiovascular disease. Additionally, the American Heart Association has shown that regular exercisers have a decreased physiological response to stress, exhibit less anxiety and depression, and have better self-esteem. Objective: To examine the pre-operative risk factors and post-operative course of recovery for regular exercisers in cardiac surgery patients. Methods: A review was done of patient generated history forms and medical data for 281 patients that underwent isolated CABG at our institution since 2007. Only 166 patients had complete history forms: 98 patients were determined to be regular exercisers prior to CABG surgery, compared to 68 non-exercisers. A subset of patients (64 exercisers and 44 non-exercisers) also completed the SF-12 to measure health related quality of life (HRQL) at baseline and 12 months post-operatively. Results: Analyses found that the regular exercisers presented with better pre-operative risk factors than the sedentary patients, including lower BMI (t=2.6, p<0.02), lower STS morbidity/mortality risk score (t=3.3, p<0.003), lower logEuroScore (t=1.9, p=0.058), and fewer patients with diabetes (OR=0.47, p<0.04). The regular exercise group was also less likely to report depression (6% vs. 16%; Chi-square = 4.2, p<0.04) and presented with a higher physical composite HRQL at baseline than the non-exercisers (t=-3.6, p<0.001). Post-operative HRQL scores indicated that while both groups increased significantly from baseline to 12 months on physical composite scores, only the regular exercisers significantly improved on the mental composite scores (t=2.2, p<0.04). Conclusion: The importance and overall cost-benefit of regular physical activity can not be overemphasized. Regular exercisers have been shown to be at reduced risk for an adverse cardiac event. For those that must undergo cardiac surgery, the physically active present with reduced pre-operative risk and superior physical HRQL. Regular exercisers also experience greater post-operative improvements in mental HRQL as compared to their sedentary peers.
