Dear Editor,

We read with great interest the article by Nezami et al. [1] on the evaluation of the outcomes of selective coil embolization of the cystic duct stump via percutaneously placed drainage catheters in patients with postcholecystectomy bile leaks.

We would like to make few constructive observations on the pathophysiology of these bile leaks related to the described technique.

On the base of our expertise in this field [ 2, 3, 4], we noticed that if the abdominal drain was next to the origin of the leak (the cystic duct stump), it favors the atmospheric-biliary pressure gradient on the biliary-duodenal gradient (even if a complete biliary sphincterotomy is performed) as we explained in our paper [ 2]; for this reason, the bile continues to flow out (Figs.  1, 2). This role of pressure gradients must be always kept in mind. The solution that we proposed, after endoscopic treatment, is to retrieve the abdominal drain 2–3 cm far from the cystic bile leak [ 2].
