We read with great interest the recently published letter to the editor by Z. Al-Asadi et al. in this journal, which describes the use of shear-thinning conformable embolic gel for the occlusion of a bronchobiliary fistula [
1]. The authors successfully utilised an embolic gel (Obsidio, Boston Scientific, Inc., Marlborough, MA, USA), which is indicated solely for peripheral vascular use, in the management of a bronchobiliary fistula. To the best of our knowledge, no previous reports in the literature have documented such an application. There is no standardised approach for the non-surgical management of bronchobiliary fistulas. Among percutaneous treatment options, case reports have described the use of glue, coils, plugs, and covered stents [
2]. Of these, glue is more commonly employed [
3]. However, despite its effectiveness, glue carries significant risks, particularly migration into the biliary system, which can result in severe complications. In this context, we believe that the present case represents a valuable contribution to the literature. Additionally, we aim to further contribute by sharing the outcomes of an absorbable haemostatic sponge (Spongostan™, Ferrosan Medical Devices A/S, Søborg, Denmark), which we employed in a similar case of bronchobiliary fistula. …
