Arm Type
No Intervention
Experimental
Arm Label
Control
Omega-3
Arm Description
Patients undergoing standard laparoscopic colorectal resection with no omega-3 enriched peri-operative nutritional support
Patients in this group will receive 7 days pre and 7 days post surgery of a nutritional supplement enriched with 1.42g/dose of the fish oils EPA and DHA. The supplement is pre-mixed and will be taken twice daily for a total of 14 days.
Outcomes
Primary Outcome Measures
Changes in Phagocytosis of pathogens
Phagocytosis of E.Coli, S.Aureus and Candida measured with flow cytometry
Changes in cell membrane composition
Using gas chromatography, measuring the percentage of omega-3 within cell membranes
Secondary Outcome Measures
Infectious complications
Descriptions laid out in supplement 1 for diagnostic criteria
Non-infectious complications
Descriptions laid out in supplement 1 for diagnostic criteria
Length of hospital stay
Length of stay in days as per electronic discharge records
Sarcopenia
Changes in body composition measured on CT scan
Quality of Life (EORTC: QLQC30)
Quality of life questionnaire EORTC: QLQC30. A 30 element validated questionnaire. Symptoms are grouped into scales: Physical Function, Role Function, Emotional Function, Cognitive Function, and Social Function. In addition symptom scales including: Fatigue, Nausea, vomiting, pain, dyspnoea, insomnia, appetite loss, constipation, diarrhoea, and financial difficulties. 28 of the scales range from 1 to 4, 4 being most symptomatic, 1 least so. The 2 remaining scales for overall health and quality of life are scaled 1-7, with 7 being the best and 1 the worst. The 30 questions can be combined for a global score, in which instance the 2 global scales are reversed so that 7 becomes the worst quality of life or health and 1 the best.
Changes in Hand grip strength
Physical measurement of hand grip strength using hand dyanamometer to assist in diagnosis of sarcopenia / functional status.

5. Study Description
Brief Summary
Bowel cancer is the second most common cause of cancer-related death in the UK, with 50,000 new cases and over 15,000 deaths annually. Surgery is the mainstay of treatment and the most common complications are an infection of the wound or lungs. These can lengthen hospital stay, reduce the quality of life, and even increase the risk of death. Bowel cancer patients are often malnourished. Optimising nutrition with supplements such as fish-oils can improve the immune response of patients, helping prevent such complications, shorten hospital stay, improve quality of life and overall survival.
Detailed Description
Bowel cancer is the second most common cause of cancer-related death in the UK, with 50,000 new cases and over 15,000 deaths annually. Surgery is the mainstay of treatment and the most common complications are an infection of the wound or lungs. These can lengthen hospital stay, reduce the quality of life, and even increase the risk of death. Bowel cancer patients are often malnourished. Optimising nutrition with supplements such as fish-oils can improve the immune response of patients, helping prevent such complications, shorten hospital stay, improve quality of life and overall survival. We are increasingly familiar with the term BMI, body mass index, which we use to categorise obesity in healthcare. A newer term in this realm is that of sarcopenia, a low muscle mass relative to your size, unrelated to your weight or fat density. This can be measured in a number of ways, including on a scan performed routinely in bowel cancer care, a CT scan. Evidence shows that people with low muscle mass, irrespective of their overall weight, experience more complications than those who have healthier amounts of muscle. We hypothesise that patients supplemented with fish oils both before and after surgery will experience an enhancement of their immune response, and subsequently encounter fewer infectious complications, a shorter length of hospital stay and improved quality of life. We also predict fewer patients having extra nutrition before and after surgery will develop sarcopenia and avoid the risks associated with that condition. The trial will only take place in those with bowel cancer who are planned to have a keyhole operation, as this is now the most commonplace approach to surgery. We plan to recruit 40 patients, 20 to receive the supplement, and 20 to form a comparison or control group.
