Summary

This trial compares two methods of bowel cleaning for patients having rectal surgery. One method uses Fleet enemas, which are inserted into the rectum, while the other uses Pico Salax, a drink. The goal is to determine which method provides better visibility and cleanliness for the surgery.

Who is the study for?
This trial is for individuals under 75 years old with colorectal cancer who are scheduled for transanal endoscopic surgery at the QEII Health Sciences Center. Candidates must be able to self-administer enemas and not have conditions like inflammatory bowel disease, previous pelvic radiation, congestive heart failure, or chronic constipation.
What is being tested?
The study compares two methods of bowel preparation before rectal surgery: Fleet Enema versus Pico-Salax oral solution. It aims to determine which one better cleanses the rectum by using a modified Ottawa Bowel Prep Scale.
What are the potential side effects?
Potential side effects may include discomfort from administering an enema, dehydration or electrolyte imbalance due to bowel cleansing agents, abdominal cramping, nausea, and possible irritation of the anus or rectum.

Trial Design

2Treatment groups
Active Control
Group I: Fleet EnemaActive Control1 Intervention
Patient is to administer one sodium bisphosphate (Fleet) enema at home 2 hours prior to arrival for surgery and a second enema one hour prior to arrival for surgery. Each 120 mL application of rectally administered enema contains 19g of monobasic sodium phosphate and 9 g of dibasic sodium phosphate. Patient is to follow standard packaging instructions from the manufacturer.
Group II: Pico SalaxActive Control1 Intervention
Patient is to take Pico Salax oral bowel preparation which is a combination product consisting of 10 mg picosulfate sodium, 3.5 g magnesium oxide, and 12 g citric acid per sachet the day prior to surgery. Patient is to take 2 doses of this product, as per standard packaging instructions from the manufacturer. Specifically patient is to take the first packet contents dissolved in 150 mL water at 3pm the day before surgery. Patient is to take the second packet dissolved in 150 mL water at 8pm the day before surgery. Patient should drink 2-3L of clear liquids after each dose, for a total of 4-6L.

Other Research
Common treatments for colorectal cancer include chemotherapy, surgical resection, and bowel preparation methods. Chemotherapy agents like oxaliplatin and S-1 work by damaging the DNA of cancer cells, thereby inhibiting their ability to replicate and grow. Surgical resection involves physically removing the tumor from the colon or rectum, which is often necessary for localized cancer. Bowel preparation methods, such as Fleet enemas and Pico Salax, are used to cleanse the bowel before surgery to ensure clear visibility and reduce the risk of infection. These treatments are crucial for colorectal cancer patients as they aim to eliminate cancer cells, prevent recurrence, and prepare the body for effective surgical intervention.
