Experience with Stent Placement for Benign Pancreaticobiliary Disorders in Children.

Purpose: There is a lack of experience with stenting for benign pancreaticobiliary disorders in children. Materials and Methods: Fifteen children (9 male and 6 female) with a median age of 7.1 years (range 0.7-14.2 years) who underwent treatment with a plastic stent for a benign disorder of the pancreaticobiliary system between May 2003 and September 2017 were recruited to this retrospective study. Results: Biliary and/or pancreatic plastic stents were inserted into 5 patients with congenital, 4 with post-traumatic, and 6 with idiopathic pathologies. Median duration of individual stent placement was 111 days (range 14-1569 days). Eleven children (73%) were treated with one stent only. In 4 cases, up to 22 stents were successively placed over time. There were no complications during stent insertion or stent removal. Seven patients (47%) experienced adverse effects during stenting, including choledocholithiasis, pancreaticolithiasis, cholangitis, acute pancreatitis, stent obstruction, and stent fracture. At follow-up, in 11 cases (73%), the underlying condition was resolved. In 4 children, all of whom suffered from congenital pancreaticobiliary disorders, stent therapy was considered as a temporary treatment before definite surgery. Conclusions: Patients with congenital anomalies of the pancreaticobiliary tree often require surgery for definitive management. However, temporary stent placement can be accomplished safely and successfully and this serves as a bridge to temporize their obstructive process while awaiting surgical intervention. Children with post-traumatic or idiopathic disorders can frequently be managed definitively by stenting alone and many of these require only one single stent insertion.
