Thank you for your comment.

In this paper, we reported our own experience with diphenylhydantoin (DPH). On the basis of this experience, as well as the wide literature search that we conducted, we personally believe that DPH is superior to the most widely used medication (Diazoxide) in suppressing insulin secretion, Refs. [1], [2]. Our article is published in the category of a Case Report, based upon personal experience, and is not intended to generate recommendations or guidelines. We suggest considering DPH as a temporary therapeutic measure in the preoperative period of patients with insulinoma, as well as an alternative measure for inoperable insulinomas, something that has already been successfully done by others [3], [4].
