The study is a cross-sectional survey study targeting patients aged 45-75 who had their screening or surveillance colonoscopy postponed or delayed due to the COVID pandemic. Study staff will survey a random subsample of patients to assess anxiety, COVID risk tolerance, cancer worry, willingness to screen and barriers to screening colonoscopy, and preference for colonoscopy and alternative colon cancer screening options. Eligible patients will be sent a survey packet in the mail that will include a cover letter, an information sheet describing the study, an incentive, and the survey. The cover letter will include information for participants to opt-out if they desire. Patients will be asked to complete the survey and return it back to study staff. Consent is implied with return of the survey. For the study, staff plan to invite 300 patients and expect to receive 195 completed surveys. Analyses will examine whether COVID-19 has changed patients' interest in colon cancer screening and the strength of patients' preferences for colonoscopy and other approaches to colon cancer screening. It will then examine factors associated with positive and negative views on rescheduling colonoscopies such as anxiety, worry, and risk perceptions.

OBJECTIVE: The aim of the study is to demonstrate that the intracorporeal resection and anastomosis in left-sided colon cancer, sigma and upper rectum, is not inferior to extracoprporeal resection and anastomosis, in terms of anastomotic leakage. BACKGROUND: Due to the recent events of a pandemic respiratory disease secondary to infection by SARS-CoV-2 virus or coronavirus 19 (COVID19), surgeons have been forced to adapt our surgical procedures in order to minimize exposure to the virus as much as possible. Based on the recommendations in case of surgery in patients with highly contagious viral diseases, the latest studies suggest minimally invasive accesses to minimize the risk of contagion. One of the proposed measures is the performance of intracorporeal anastomoses. Therefore, given the extensive experience of our center in minimally invasive surgery and studies on the validation of intracorporeal anastomosis techniques in both laparoscopic surgery of the right colon and rectum (TaTME), and the study of advantages that they can provide to the patient, our intention is to apply it to surgery on the left colon, sigma and upper rectum. Our hypothesis is that exteriorization of the colon through an accessory incision increases the risk of tension at the mesocolon level, thus increasing the risk of vascular deficit at the level of the staple area and it may increase the rate of anastomotic leakage. In this sense, studies that validate a standard technique of intracorporeal anastomosis in left colon surgery and that demonstrate its benefit with respect to extracorporeal anastomosis are lacking. We intend to describe a new intracorporeal anastomosis technique (ICA) that is feasible and safe for the patient and that can be applied universally. Once the ICA technique is established, it will allow us to determine its non-inferiority compared to the standard technique performed up to now with extracorporeal anastomosis. METHODS: All consecutive patients with left-sided, sigma and upper rectum adenocarcinoma will be included into a prospective cohort and treated by laparoscopy with totally intracorporeal resection and anastomosis. They will be compared with a retrospective cohort of consecutive patients of identical characteristics treated by laparoscopy with extracorporeal resection and anastomosis, in the immediate chronological period.

The global cancer burden is estimated to have risen to 18.1 million new cases in 2018 (WHO), with a trend of ongoing growth. This very frequent illness exerts tremendous physical, emotional and financial strain on individuals, families, communities and health systems. Malnutrition (under- or over-nutrition) is highly prevalent in cancer patients receiving chemotherapy and is an important predictor of morbidity, mortality, treatment response and toxicity. Alterations in taste and smell are frequently reported as side effect of chemotherapy and may contribute strongly to malnutrition and to a worsen quality of life and wellbeing social, emotional, and role functioning. There are evidences that chemotherapy influences food liking and appetite with implications for food behaviours, including food enjoyment, food preference and dietary intake. A linkage between alterations in taste and /or smell and food behaviours has been reported by some studies but not all, suggesting that there is a need for more research using common standardised methodologies and larger sample size to gain a further insight into this topic.
