E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study will be to compare Targinact (prolonged release naloxone + oxycodone) with current standard treatment (oxycodone alone) in post-operative return of normal gut function after elective colorectal resectional surgery. |
|
E.2.2 | Secondary objectives of the trial |
Since this is a pilot trial of a complex intervention, the study will gather data on aspects of study design, such as protocol compliance and treatment effect size, and record comprehensive data on return of gastrointestinal function with a view to deriving a composite end-point definition for the design of subsequent larger trials in colorectal surgery. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients scheduled for elective laparoscopic hemicolectomy at the Colorectal Surgery Unit, Western General Hospital, Edinburgh. |
|
E.4 | Principal exclusion criteria |
Pregnancy Patients lacking capacity to give informed consent. Severe liver dysfunction (Child’s A or greater) Patients participating in another therapeutic clinical trial Contraindication to oxycodone, naloxone or Targinact Pre-existing dependence on opioid analgesia (current medications will be checked prior to discussing consent) Pre-existing use of opioid analgesia for chronic pain (current medications will be checked prior to discussing consent) Patients with rectal cancer Plan to form any stoma during procedure

E.5 End points |
E.5.1 | Primary end point(s) |
25% reduction in rate of gut dysfunction (defined as nausea, vomiting, intolerance of oral intake or constipation sufficient to delay discharge) on programmed day of discharge (3rd postoperative day). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Equivalence of pain control Measured by: • Total quantity of Morphine Rescue PCA used over standard analgesia protocol (see perioperative management protocol) • Total dose of oral Oxycodone or Targinact until discontinued by the patient/discharged from hospital • Pain scores will be recorded using the OBAS multi-dimensional quality assessment tool. This assesses pain at rest, overall satisfaction with pain relief in previous 24 hours and side effects of analgesia (sweating, itching, vomiting, dizziness). • Activity monitors will be used to measure mobilisation and inform the assessment of dynamic pain relief
Return of gut function Multiple measures will be employed to record both presence of good function and absence of dysfunction • Time to first flatus • Time to first bowel movement • Time from surgery to cessation of iv fluids (excluding 10ml/hr used to maintain patency of PCA) • Total dose of rescue antiemetic (protocol ondansetron not included) • Reinstitution of iv fluids due to inadequate oral intake (Y/N) • Measurement of oral nutritional intake: Preoperative intake will be recorded by means of a recall diary. Postoperative oral intake will be recorded by the patient using a food diary for 7 days from the date of surgery, supplemented by digital photography to calculate the protein/calorie content of what was offered at mealtimes and what was actually consumed. Energy intake will then be estimated using CompEat Pro® forWindows® (Nutrition Systems, Banbury, UK). Time to attain and maintain 80% of normal solid food intake and the percentage Recommended Nutritional Intake (RNI) achieved on the first 3 days after surgery for each subject will be used in comparisons between study groups. • Validated nausea and vomiting score (Miles and Wengritzky) • Presence of abdominal distension (Y/N) • 13C Stable Isotope Gastric Empting Breath Test to measure gastric motility on the second postoperative morning[10]. The technique has been previously used in the Edinburgh School of Surgery and validated as a reproducible and accurate measurement of upper GI motility.
Additional data to be recorded: • Patient demographics, co morbidity, regular medications • Pre op bowel function questionnaire • PONV prediction data (Apfel score) • Day 3 achievement of discharge criteria (pain controlled by oral analgesia, tolerating adequate oral diet and fluids, independently mobile and nausea controlled by oral medication) Y/N • 30-day/Inpatient mortality • Duration of hospital admission • Complications (recorded by organ system and severity as assessed by Clavien/Dindo scale) • Unscheduled readmissions to hospital within 30 days of discharge • Protocol compliance analysis • Patient-reported outcome questionnaire
