Abstract:
Background:/Aim: Endoscopic retrograde cholangiopancreatography (ERCP) is one of the useful treatment for treating diseases that cause pancreatic duct stenosis. However, if the stenosis is severe, accessories other than the guide wire cannot pass through. This makes the ERCP procedure difficult. At this time, cystotome, a type of diathermic dilator seems to be an option. In this paper, we would like to discuss the experience of treatment procedures using cystotome.
Methods:Patients who underwent ERCP at a single tertiary hospital from November 2019 to October 2022 were analyzed retrospectively. Among them, cystotome was used in eight procedures in seven patients who passed the guide wire but failed to pass the stenosis.
Results:Technical success was achieved in all eight times. All the balloon catheter smoothly passed through the stenosis after cystotome was performed. In the second ERCP, it was a functional success for the balloon catheter to pass through stenosis without further treatment. This was achieved in 6 out of 8 (75.0%). In the case of complications, only one of the total successful procedures developed mild pancreatitis, which led to additional hospitalization for about two days after the procedure, and improved after conservative treatment.
Conclusions:Based on this, cystotome seems to be a good option as an alternative treatment to severe stenosis of the pancreatic duct.
