Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Addition of 50g per day of high amylase resistant starch to usual diet to determine changes in stool output.
Participants will act as their own control as this is a crossover trial. Each participant will complete the control and intervention arm of the trial.
Each arm of the trial will last for 1 week, as week one is a control (usual diet and fluids) period no wash out is required.
Participants will self administer the resistant starch by adding 1tbl per glass of St marks solution 4 times daily.
Resistant starch is a soluble tasteless powder which is undetectable in food and fluids.
Intervention code [1] 299984 0
Treatment: Other
Comparator / control treatment
Participants will act as their own control by completing a one week observation period prior to the intervention.
The control period involves the participants taking their usual diet which includes 1L per day of st Marks oral rehydration solution. Participants are advised not to make any changes to their usual diet during the control / intervention
Control group
Active

Outcomes

Timepoint [1] 304378 0
Stool output (g/d) will be measured on days 2, 4 and 7 of each trial week (i.e. both control and intervention period)..

Summary
Brief summary
Short bowel syndrome is defined as not having enough bowel to be able to absorb enough nutrition from food to maintain body weight. Short bowel syndrome causes diarrhoea and large fluid losses as a result of not being able to absorb what has been eaten / drunk. This means many people with short bowel syndrome rely on intravenous nutrition and or hydration.

Recent studies have shown that adding resistant starch (a form of carbohydrate found in food) to rehydration solutions that you drink can reduce diarrhoea in cases from a number of different causes. There are no studies investigating the use of resistant starch to reduce stool output in participants with short bowel syndrome.

It appears as though resistant starch works when it is fermented by the bacteria that live in the large bowel. A by-product of this fermentation are short chain fatty acids (SCFA). SCFA’s increase the large bowel’s ability to absorb water and salts leading to less diarrhoea and fluid loss.

The aim of this study is to determine if adding resistant starch to a rehydration solution that you drink can reduce diarrhoea and fluid loss in people with short bowel syndrome. If it is effective it may have the potential to reduce the amount of IV fluids needed for some people.

Resistant starch is present naturally in some foods and is approved as a food additive to increase the dietary fibre content.

This trial is aimed to determine if resistant starch can decrease diarrhea in people with short bowel syndrome.

It is a 2 week trial. Participants will complete both the control and the intervention.
In the treatment group you will be provided with 50g of starch powder to add to St Marks’s oral rehydration solution. You will be asked to drink 4 glasses of St Mark’s solution daily, each containing a tablespoon of the powder.

In the control group participants will be asked to drink 4 glasses of St Mark’s solution daily without any additions.

During each study period participants will otherwise eat and drink as normal and asked not to make any dietary changes during the study periods.

During the trial period participants will be asked to record the number of bowel actions they have each day and on days 2, 4 and 7 you will be asked to weigh each bowel action with scales that will be provided to record a daily total.

Results will be compared between groups
