Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients presenting with food bolus, will have endoscopy performed by a gastroenterologist or gastroenterology trainee under the supervision of a gastroenterologist.
Patient with food bolus distance > 20 cm from incisors will be randomized to receiving either the study drug (2%peppermint oil) or placebo. This will be instilled at an initial volume of 10mls and delivered endoscopically, followed by a further 10mls one minute later if there is no spontaneous resolution of the food bolus. Should there be no spontaneous passage of SFBO one minute after the second administration then a gentle push technique will be trialled. If the push technique fails, then retrieval of the SFBO will be using equipment at the discretion of the endoscopist.
The total duration of the endoscopy is one of the end points that will be measured. Should the peppermint prove successful then the duration of endoscopy in the study arm will be significantly shorter. Difficult food bolus obstruction can sometimes take over 2 hrs to disimpact. Adherence to intervention will be monitored by documentation during procedure.

Comparator / control treatment
Control group will receive placebo (sterile water), initial volume of 10mls delivered endoscopically, followed by a further 10mls one minute later, if there is no spontaneous resolution of the food bolus.
Should there be no spontaneous passage of SFBO one minute after the second administration then a gentle push technique will be trialled. If the push technique fails, then retrieval of the SFBO will be using equipment at the discretion of the endoscopist
Control group
Placebo

Outcomes
Primary outcome [1] 329235 0
Ability of Mentha Piperita to shorten duration of endoscopic procedure. The total procedure time is recorded on the reporting software. The procedure start and end times are bookmarked by the nurse on this software (i.e "scope in" and scope out" times) during the procedure.
Timepoint [1] 329235 0
At time of endoscopy
Secondary outcome [1] 401858 0
Ability of Mentha Piperita to cause spontaneous passage of food bolus. This will be recorded on a data collection sheet by the endoscopist.
Timepoint [1] 401858 0
At time of endoscopy
Secondary outcome [2] 402652 0
Ability of Mentha Piperita to improve success of push technique for SFBO. This will be recorded on a data collection sheet by the endoscopists. I.e was the food bolus able to be pushed into stomach if it failed to pass spontaneously or did it require extraction using other instruments.

At time of endoscopy

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed opaque envelope
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Blocked randomisation will occur, in blocks of 10 participants.
10 sealed opaque envelopes, five for each study arm.
One envelope is selected for each subject at time of endoscopy.
This will be repeated for each subsequent block.
Masking / blinding
Open (masking not used)

Efficacy
Statistical methods / analysis
As this study is a “proof of concept study” a sample size calculation was not performed. We anticipate recruiting 40 patients to this study, 20 in each arm over a time period of two years.

Descriptive statistics for the cohort will be generated.
Continuous variables will be summarized using means and standard deviations or medians and interquartile ranges, and categorical variables using frequencies and percentages.
Continuous data will be compared between the two arms using t test or Mann-Whitney U test while Categorical data will be compared using Chi-squared test.

Summary
Brief summary
Oesophageal soft food bolus obstruction (SFBO) is a common gastroenterological presentation. Mentha piperita, the active component of peppermint oil has been proposed as an adjunct in SFBO. This study is to evaluate the effectiveness of Mentha Piperita in facilitating spontaneous passage of SFBO and improving effectiveness of the endoscopic push technique, via a prospective randomised control trial.

To check effectiveness of peppermint oil in relieving blockage from food stuck in the food pipe.
