Use of Beetroot Juice to Protect Against Postoperative Ileus (POI) Following Colorectal Surgery: a Pilot Study.

An interventional study of Beetroot juice and Nitrate-depleted beetroot juice in Postoperative Ileus, sponsored by University Hospital, Ghent. Terminated at 1 site in Belgium. Open to participants aged 18 Years to 95 Years. Per ClinicalTrials.gov, last updated 2023-01-20.

Sponsored by University Hospital, Ghent · Not applicable, Interventional, and Prevention

Why this study was terminated
The pilot study was set up to assess whether the used dosing regimen of beetroot juice demonstrated to reach the therapeutic objective. The study was terminated early, as the deadline for the grant application for a larger study was approaching.

Study summary

The BEET IT study investigates the possible protective effect of beetroot juice on POI following colorectal surgery in (partially) blinded single-center phase 2 randomized trial (pilot study).

Read the detailed description

Postoperative ileus (POI) is a transient impairment of gastrointestinal motility following abdominal surgery, which leads to increased morbidity, prolonged hospitalization and increased healthcare cost. The pathogenesis of POI involves inflammation and oxidative stress, similar to ischemia/reperfusion injury that can be counteracted with beetroot juice. Beetroot juice is a source of inorganic nitrate, which by conversion of nitrate to nitrite in the body, exerts its protective effect. We before demonstrated in a preclinical model that administration of exogenous nitrite was shown to protect against POI. The aim of this pilot study is to investigate the possible protective effect of beetroot juice ingestion on POI following colorectal surgery.

Inclusion criteria

  • All patients undergoing colonic or upper rectum laparoscopic surgery.

Exclusion criteria

Exclusion Criteria:

  • Pregnancy or breast feeding
  • Psychiatric pathology capable of affecting comprehension and judgment faculty
  • History of disease
  • History of prior abdominal bowel surgery
  • Abdominal radiation treatment
  • Chronic constipation (defined as two or fewer bowel movements per week)
  • Gut motility influencing agents (e.g. tricyclic antidepressants, chronic use of laxatives)
  • Frequent use of mouthwash, as this affects the enterosalivary circulation of nitrate
  • Current use of broad-spectrum antibiotics, which will affect the oral flora and likely affect the nitrate reductase activity
  • More than one bowel anastomosis during this surgery
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

What researchers measure

Primary outcomes

  1. Time until recovery of gastrointestinal function.

    Recovery of gastrointestinal function is defined as the interval (in days) from the end of surgery until passage of stool AND tolerance of solid food.

    Time frame: up to 30 days after surgery

Secondary outcomes

  1. Time until passage of stool, flatus or until tolerance of (semi-)solid oral diet (in days).

    Time frame: up to 30 days after surgery

  2. Overall post-operative complication rate defined according to the Clavien-Dindo Classification.

    Time frame: 3 months postoperatively

  3. Presence of prolonged postoperative ileus.

    Prolonged postoperative ileus is defined as presence of 2 or more of the following criteria on or after day 4 postoperatively: nausea or vomiting, inability to tolerate a solid or semi-solid oral diet, abdominal distension, absence of flatus and stool, radiological evidence of ileus.

    Time frame: up to 30 days after surgery
