The focus of our study was to explore and report on our experience with EUS latex balloon use in patients with a self-reported latex allergy.

The use of a fluid-filled balloon improves acoustic coupling and visualization during EUS-guided procedures. We perform thousands of EUS procedures a year, and some patients have a self-reported latex allergy, precluding latex balloon use.

Anecdotally, we noticed patients do not experience adverse events with latex balloons, and obtaining latex-free balloons can be associated with increased costs. Therefore, we wanted to report on our experience.

Our study found that latex balloon use was not associated with adverse events such as anaphylaxis or angioedema. Latex balloon use was safe whether prophylactic medications were used during the EUS procedures.

Despite our findings, patients should be adequately informed about latex balloon use if they have a reported latex allergy, and routine monitoring should be performed. Hopefully, this study reduces the need for obtaining latex-free balloons when enhanced acoustic coupling is necessary.
