# Urgent Endoscopic Biliary Procedures: “Run Like the Wind”?

## TL;DR

This paper reviews which biliary tract conditions need urgent endoscopic treatment and discusses the implications for healthcare organization.

## Contribution

The paper clarifies which biliary tract pathologies require urgent endoscopy and outlines organizational strategies based on international guidelines.

## Key findings

- Severe acute cholangitis (ACh) requires urgent endoscopic treatment within 12 hours.
- Other biliary tract conditions can be treated within 72 hours, allowing for more flexible scheduling.
- Organizational challenges arise due to the need for trained biliary endoscopists available 24/7.

## Abstract

Emergency endoscopy is an activity that must be guaranteed 7 days a week and 24 h a day. The pathologies of endoscopic interest that require emergency intervention are mainly hemorrhages of the upper digestive tract, the removal of foreign bodies, and the ingestion of caustics. The emergency endoscopist must therefore be experienced in the management of these pathologies. Nowadays, however, we know that even some biliary tract pathologies must be managed within a variable period between 12 and 72 h, in particular acute cholangitis (Ach), acute biliary pancreatitis (ABP), biliary duct leaks (BDLs), and acute cholecystitis (AC). If, on one hand, there is little awareness among doctors about which pathologies of the biliary tract really deserve urgent treatment, on the other, the international guidelines, although not uniformly, have acquired the results of the studies and have clarified that only severe Ach should be treated within 12 h; in other cases, endoscopic treatment can be delayed up to 72 h according to the specific condition. This obviously has a significant organizational implication, as not all endoscopists have training in biliary tract endoscopy, and guaranteeing the availability of a biliary endoscopist 24/7 may be incompatible with respecting the working hours of individual professionals. This review aims to evaluate which pathologies of the biliary tract really require an endoscopic approach in emergency or urgency and the organizational consequences that this can determine. Based on the guidelines, we can conclude that a daytime availability for urgent biliary tract procedures 7 days a week should be provided for the management of severe ACh. Patients with ABP, AC unfit for surgery, and not responsive to medical therapy or BDLs can be treated over a longer period, allowing its scheduling on the first available day of the week.
