Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
ERCP is commonly performed in either the left lateral decubitus or prone position.
The left lateral decubitus position for performing ERCP will be in half of the randomised group.
Measurement of time to biliary cannulation and complication rates will be recorded.

Treatment: Other
Intervention code [2] 291315 0
Diagnosis / Prognosis
Comparator / control treatment
Comparator group will be active group of patients undergoing ERCP but those that have been randomised to the prone position.
Similar parameters as outlined in the "active/intervention" group will be assessed.
Control group
Active

Secondary outcome [1] 313009 0
The secondary objective is other complications including perioperative cardio-respiratory anaesthetic complications and other complications directly as the result of ERCP - this will be assessed by reviewing the vital signs recorded during the procedure, reviewing the patient's electronic medical records, and where apropriate - a phone call to the patient at 4 weeks post procedure
Timepoint [1] 313009 0
immediate and 4 weeks

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A suitable subject will be randomised to a position as determined by the position allocation concealed within a sealed opaque envelop e.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified allocation was performed to ensure equal numbers of both genders are enrolled, and that half of each gender cohort will be randomised to one of two positions.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Other
Other design features
Parallel with crossover.
Subjects are randomised to an initial position for performing the procedure. If the procedure is unsuccessful in that position, they will be repositioned to the other position, but they are not acting as control for themselves.
Phase
Not Applicable
Type of endpoint(s)
Safety/efficacy
Statistical methods / analysis
If there is no significant difference between the standard and the experimental treatment groups, then 194 patients are required to be 90% sure that the upper limit of a one-sided 95% confidence interval (or equivalently a 90% two-sided confidence interval) will exclude a difference in favour of the standard group of more than 10%.

Summary
Brief summary
Patients having an ERCP may have the procedure lying on their left side or on their stomach. Currently, the position chosen is decided by the doctor performing the procedure. We do not know if one position is better than another. This project aims to assess whether the position a patient is in affects the ease and time taken to perform the procedure as well as any affect this may have on the rate of potential complications.
