Abstract
Background: The strategy for choledocholithiasis in surgically altered anatomy (SAA) has changed over time. This study aimed to clarify the current status of endoscopic treatment.
Patients and Methods: We retrospectively reviewed 491 patients with choledocholithiasis who received endoscopic treatment from 2008 to 2019. The patients with SAA were divided into early group (2008-2013, n=17) and late group (2014-2018, n=26). The patients with normal anatomy were categorized as normal group (n=448). The treatment outcome was evaluated.
Results: The usage rates of double-balloon endoscope (DBE) and salvage therapy in the late group were increased compared with that in the early group. The stone removal rates in the early, late and normal groups were 70.6%, 100% and 98.7%, respectively. The outcome in the late group was superior to the early group and equal to the normal group.
Conclusions: DBE and appropriate salvage therapy increase stone removal rate in patients with SAA, which can be comparable to those in patients with normal anatomy.
