Use of a Novel Camera to Check the Bowel After Polyp or Tumour Removal

1.1 Polyps or tumours in the lower part of the bowel (rectum) can be removed using instruments inserted through the bottom which avoids major surgery and the possibility of a stoma bag (colostomy). Afterwards, it is important to check the area with regular camera tests. If checks are delayed, re-growths could be serious and may be untreatable. COVID and other factors have led to long waiting lists for camera checks and in NHS Lothian around 20% of all camera checks are done more than 6 months late. The investigators want to try a new camera and approach that would allow us to reduce waiting lists. Using a short camera called a 'rectoscope' to check the lower bowel has already been shown to be safe, comfortable and acceptable to patients with other conditions. In fact, patients are unlikely to feel or realise any difference between the rectoscope and standard camera tests. The investigators want to show that this 'rectoscope' can be safely used in the outpatient clinic with an enema (suppository) instead of strong bowel medicine taken by mouth the day before. This would mean the camera checks happen on time and would reduce waiting lists for other important tests. The investigators will include 30 patients across three stages of our study. In the first set of patients, the investigators will use the rectoscope alongside the usual endoscope in the endoscopy room using the usual oral bowel medicine. This stage will check the rectoscope is acceptable to the patient and the doctor. In the next 10 patients the investigators will use a suppository instead of oral bowel medicine still using both cameras. Finally, the investigators will use the rectoscope in the outpatient clinic with an suppository to show this is an easy, effective and acceptable way to deliver timely camera checks.

Safety and Effectiveness Study of Pre-operative Artesunate in Stage II/ III Colorectal Cancer

TThis study evaluates the safety and effectiveness of pre-operative artesunate, given orally once a day for 14 days prior to surgery, in patients with Stage II/III colorectal cancer. Artesunate is an established antimalarial drug with an excellent safety profile. It is well tolerated, affordable, and widely available. Several laboratory studies and one small pilot clinical study in patients with colorectal cancer have shown that artesunate can reduce the proliferation and growth of cancer cells. One hundred patients diagnosed with Stage II/III operable colorectal cancer will be randomly allocated to receive oral artesunate 200 mg daily or a matching placebo for 14 days prior to surgery. Patients will then be followed closely for 5 years to determine whether pre-operative artesunate reduces the risk of cancer recurrence after surgery.

EQUITA - A Feasibility Trial of a Faith-placed Intervention to Increase Screening Uptake in Black Adults

The goal of this randomised feasibility trial is to examine feasibility and acceptability of a co-produced and faith-placed intervention to increase uptake of breast, cervical, bowel, and abdominal aortic aneurysm (AAA) screening among Black communities in the North East of England, Leeds and Scotland, United Kingdom (UK). Participants will be invited to attend a two-hour workshop at each of the three study sites and will be randomly assigned to either the intervention group or the control group. This 24-month feasibility study will inform the development of a full-scale randomised-controlled trial co-produced for Black people that uses culturally appropriate messages that support screening for early diagnosis in this underserved group.

Improving Muslim Women's Uptake of Cancer Screening (IMCAN)

The goal of this non-randomised trial is to test how a workshop that includes religiously-tailored messages can help increase the uptake of breast, colorectal and cervical cancer screening among Muslim women in North East England and Scotland. The results of this trial will inform the development of a full-scale randomised-controlled trial. Participants in this study will be asked to take part in a two-hour workshop, deliver either online or in-person.

Assessing Frailty and Its Impacts on Patients Facing Major GI Surgery

The study team will look at 3 new tests that will make it easier to measure frailty in patients awaiting surgery for cancer and compare them against standard clinical measures of frailty in a pilot study. The expected outcome is that evidence will be collated in order to apply for a major grant to look at improving the care of frail patients with cancer in the future.
