[Whether or not to perform an early endoscopy following ingestion of potentially caustic agents - a retrospective longterm analysis in a tertiary referral institution]

Abstract

Background: The optimal clinical management of patients following ingestion of potentially caustic lesions is still undetermined. In particular, the indication for early upper GI endoscopy in this context remains unclear.

Purpose: To draft recommendations regarding the use of early upper GI endoscopy following hospital admissions of patients after ingestion of potentially caustic agents.

Methods: For this purpose, a retrospective cohort study of patients treated for ingestion of potentially caustic substances during a 13 year-period at the university hospital of Berne was performed.

Results: In total, 61 patients with acute ingestion of potentially caustic substances were identified. Overall mortality was 5 %. 11/61 patients had to be admitted to the intensive care unit. Most ingestions were performed in suicidal intention (62 %). In 53 % of these patients, a combined ingestion of several substances occurred. In 33 % of patients, an early upper GI endoscopy was performed within 24 hours after ingestion. The degree of burn depended upon the hazard potential of the respective substance. In patients with ingestion of low risk substances, upper GI endoscopy was only performed when additional risk factors were present.

Conclusion: Based upon the results of the present study, ingestion of potentially caustic agents requires an individualized strategy whether or not to perform early endoscopy.
