About this study

Official title: Multi-centre Double-blind Randomized Trial of the Clinical Value of Preoperative Oral Carbohydrate Loading in Colorectal Surgery.

The aim of this study is to provide conclusive clinical evidence as to whether or not the preoperative administration of oral carbohydrate-rich solutions is effective on the outcomes of patients undergoing colorectal surgery.

Read the detailed description

Preoperative oral carbohydrate loading is an issue that has been investigated extensively in terms of its fundamental and biochemically apparent effects and potential benefits. Most commonly, proponents of the application advocate that it may be beneficial for improving patient outcomes and for decreasing complication rate by attenuating postoperative insulin resistance. To date, however, no study with a sufficient sample size has been able to demonstrate that it has a marked value in clinical practice. Almost all of the clinical benefits ascribed to the application have been based on subjective well-being, which can also be provided with non specific simple beverages. A study conducted to show whether or not the application has direct influence on patient outcome, therefore, could significantly contribute insights on this topic. The present study was planned to consist of three study arms, namely: 1.Study group, which will be given high-carbohydrate beverage (Nutricia preOp®, Numico, Zoetermeer, The Netherlands) 2. Placebo group, which will be given flavored water, and 3. Control group (surgery after overnight fast). The revised power analysis shows that an accrual of 74 patients in each group would allow detecting a 15% difference in the rate of complications with 80% power at the 5% level of significance (two tailed). We hope we will have recruited at least 220 subjects at the end of a two-year course. Once the data recording is complete, this study will be the largest one ever conducted to investigate this topic.

  • commercially available high-carbohydrate beverageDietary supplement

    800 ml before the day of surgery, and additional 400 ml two hours prior to surgery

  • flavored waterDietary supplement

    will be given in doses equal to those of high-carbohydrate beverage

Questions about this trial

What is this clinical trial studying?

A study testing commercially available high-carbohydrate beverage and flavored water in people with Colorectal Disorders and Colorectal Surgery, run by Gulhane School of Medicine at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall 30-day complication rate (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2015.
