[Use of gadolinium as contrast agent in endoscopic retrograde cholangiopancreatography in patients with iodine allergy]. | LitMetric

AI Article Synopsis

Article Abstract

Introduction: Radiologic contrasts are required during endoscopic retrograde cholangiopancreatography (ERCP). The most frequently used are iodine-based contrast media. Controversy still surrounds the optimal strategy in patients with previous adverse reactions to iodine contrasts that need to undergo an ERCP.

Objective: To evaluate the safety and efficacy of a gadolinium-derived contrast medium in patients with previous reactions to iodine-derived agents during ERCP.

Material And Methods: Thirteen ERCP were performed in 11 patients with well-established adverse reactions to iodine compounds. ERCP was carried out with gadobutrol, a non-ionic gadolinium compound and without prophylaxis.

Results: In all patients, ERCP were satisfactorily completed. Thirteen cholangiograms and one pancreatogram were obtained. All procedures were technically successful, allowing diagnosis and endotherapy. The quality of the images was good, similar to those obtained with standard contrast media, and did not represent a limitation. No contrast-related adverse events were observed, and there were no post-ERCP complications.

Conclusions: Gadolinium-derived agents are a safe and effective alternative in iodine-allergic patients.
