Major resections for esophageal, gastric, hepatic, pancreatic, and colorectal cancer continue to be associated with a high peri-operative morbidity of up to 30%–40%. To a large extent, this morbidity is caused by infectious complications that add up to a considerable burden to patients and hospital costs. The objective of this large retrospective cross-sectional study was to determine independent patient and operation-related risk factors for infectious complications after major abdominal cancer operations to elucidate how infection rates can be reduced and improve health-care quality. In this study, several independent risk factors for infectious complications in major abdominal cancer operations were identified, providing opportunities for further reducing peri-operative infections.

BACKGROUND: The incidence of colorectal cancer (CRC) is highest among the elderly. An important treatment modality is surgery. After surgery, due to poor functional recovery, some elderly have an increased risk for complications and prolonged length of hospital stay (LOS). Preoperative elevated levels of fatigue and impaired functioning in instrumental activities of daily living (iADL) might be associated with these outcomes, and may, therefore, be helpful to recognize patients with elevated risk for complications or prolonged LOS, who should undergo more thorough functional assessment.AIMS: This exploratory study aims to assess whether physical fatigue, reduced activity and/or iADL, assessed preoperatively, are associated with postoperative complications and prolonged LOS, in elderly patients undergoing surgery for CRC.METHODS: We performed an exploratory prospective study in older (≥ 65 years) patients (n = 57) who were scheduled to undergo elective surgery for colorectal cancer. Fatigue and iADL functioning were assessed with questionnaires. Multivariable regression analyses were used to examine the relationship of fatigue and iADL with complications and LOS.RESULTS: IADL was not associated with complications or LOS. Fatigue was not associated with complications. Patients with higher fatigue had increased LOS in the univariable analyses but not in the multivariable analyses after adjustment for nutritional status and neoadjuvant treatment.DISCUSSION: We found that fatigue was associated with increased LOS in the univariable analysis. The results from the multivariable analysis and path analysis indicate, however, that this is likely not a causal relationship; the observed relationship between physical fatigue and LOS appears to be confounded by nutritional status and by having received neoadjuvant treatment.CONCLUSIONS: Although fatigue is a predictor for increased LOS, assessment of fatigue and iADL has no additional value for identifying elderly at risk for poor functional outcome after CRC surgery.

Background: Preoperative inspiratory muscle training (IMT) is frequently used in patients waiting for major surgery to improve respiratory muscle function and to reduce the risk of postoperative pulmonary complications (PPCs). Currently, the mechanism of action of IMT in reducing PPCs is still unclear. Therefore, we investigated the associations between preoperative IMT variables and the occurrence of PPCs in patients with esophageal cancer. Methods: A multi-center cohort study was conducted in subjects scheduled for esophagectomy, who followed IMT as part of a prehabilitation program. IMT variables included maximum inspiratory pressure (PImax) before and after IMT and IMT intensity variables including training load, frequency, and duration. Associations between PImax and IMT intensity variables and PPCs were analyzed using independent samples t tests and logistic regression analyses, corrected for age and pulmonary comorbidities and stratified for the occurrence of anastomotic leakages. Results: Eighty-seven subjects were included (69 males; mean age 66.7 ± 7.3 y). A higher PImax (odds ratio 1.016, P = .07) or increase in PImax during IMT (odds ratio 1.020, P = .066) was not associated with a reduced risk of PPCs after esophagectomy. Intensity variables of IMT were also not associated (P ranging from .16 to .95) with PPCs after esophagectomy. Analyses stratified for the occurrence of anastomotic leakages showed no associations between IMT variables and PPCs. Conclusions: This study shows that an improvement in preoperative inspiratory muscle strength during IMT and training intensity of IMT were not associated with a reduced risk on PPCs after esophagectomy. Further research is needed to investigate other possible factors explaining the mechanism of action of preoperative IMT in patients undergoing major surgery, such as the awareness of patients related to respiratory muscle function and a diaphragmatic breathing pattern.

Lymphedema is one of the most poorly understood, relatively underestimated and least researched complications of cancer, or its treatment. Lymphedema is a chronic condition that causes abnormal build up of fluid under the skin resulting in painful swelling, commonly in the arms and legs. Limpressive Compression Garments have designed and conceptualised an active and smart compression sleeve that integrates pioneering smart materials and sensor technology to be used to treat and evaluate lymphedema. The Limpressive garments can be used as a research tool while replacing existing compression sleeves and pneumatic compression apparatus. There is currently no product on the market that is integrating both the actuator and sensor technology to treat, let alone quantify lymphedema. It is thus imperative that the Limpressive Compression Garments team are allowed the opportunity through funding to investigate the feasibility of the technology and its integration into healthcare, the business structures and processes needed to enter and be successful in the marketplace and the value to both the consumer and to the organisations dedicated to developing a greater understanding of the disease. Limpressive will complete an extensive and detailed business plan and a complete product design by the end of the Take-off Phase. The business plan and complete product design will be complemented by a proof of function prototype.
