Cola Drinking May Not Provide Relief In Complete Oesophageal Food Bolus Impaction

Study on Cola and Oesophageal Food Bolus Impaction

In a recent breakthrough, a multicentre, randomized controlled trial conducted across five Dutch hospitals has explored the efficacy and safety of a seemingly unconventional remedy—cola—in treating complete oesophageal food bolus impaction. The study suggested that cola consumption did not substantially increase the rate of improvement in complete oesophageal food bolus impaction.

The study results were published in the journal The BMJ.

Background

Oesophageal food bolus impaction, a common medical emergency, peaks during holidays. Current guidelines recommend endoscopy, but previous studies suggest cola ingestion's potential efficacy. Hence, researchers conducted a trial comparing cola treatment to standard care for complete impactions, aiming to reduce emergency visits and endoscopies.

Methodology

The trial enlisted 51 adults facing complete oesophageal food bolus impaction, excluding those who ingested bone-containing meat and individuals with higher ASA physical status classifications. The intervention group (28 patients) was instructed to consume 25 mL cups of cola at intervals, up to a maximum total volume of 200 mL. In contrast, the control group (23 patients) awaited spontaneous passage. If symptoms persisted, endoscopic removal followed current guidelines. Primary outcomes focused on the improvement of food bolus obstruction and complete passage, with adverse events related to the intervention also considered.

Outcomes

Enhancement in oesophageal food bolus obstruction, reported by patients (comprising both complete and partial passage), and assessment specifically focusing on complete passage constituted the primary outcome. The secondary outcome involved any adverse events related to interventions.

Findings

Contrary to expectations, the study revealed that cola consumption did not significantly enhance the rate of improvement in complete oesophageal food bolus impaction.
Both the intervention and control groups demonstrated a 61% rate of improvement in food bolus obstruction.
Although the intervention group reported a higher incidence of complete passage (43% vs. 35%), the difference lacked statistical significance.
Importantly, no severe adverse events occurred, affirming the safety of the cola treatment.
However, 21% of patients in the intervention group experienced temporary discomfort after consuming cola.

Conclusion

The study's findings imply that while cola may offer some relief, it may not serve as a definitive solution for complete oesophageal food bolus impaction. Researchers caution against relying solely on cola, emphasizing the need for prompt endoscopic intervention when necessary. The study suggests that cola could be considered as a first-line treatment, but its use should not impede the timely planning of endoscopic management.
