ABSTRACT

Introduction

Inflammatory bowel disease (IBD), which includes Crohn’s disease (CD) and ulcerative colitis (UC), requires meticulous diagnostic and monitoring protocols to optimize patient outcomes. This document synthesizes key advancements and recommendations for clinical indices, endoscopic scoring, imaging, histological assessment, and tools for evaluating IBD disability. Emphasizing validated, reproducible methods aligns with the ongoing evolution of precision medicine in IBD care, including training. The methodology of the guidelines update process is described in part 1.

Summary

Vascular diseases of the liver include portal vein thrombosis (with or without cirrhosis), portosinusoidal vascular disorder, Budd-Chiari syndrome, sinusoidal obstruction syndrome, non-obstructive sinusoidal dilatation and peliosis, splanchnic artery aneurysms, and hepatic arteriovenous fistulas. Except for portal vein thrombosis in cirrhosis, these are all rare conditions. Since the last Clinical Practice Guidelines were issued by the European Association for the Study of the Liver in 2016, much data has been published on the diagnosis and management – medical and interventional – of patients with vascular liver diseases. Based on a thorough review of the relevant literature, recommendations are provided to address key clinical dilemmas. The document emphasises personalised care, considering individual risk factors and clinical presentation. Multidisciplinary management involving hepatologists, haematologists, pathologists, interventional radiologists and surgeons is essential in this area. Our aim is to provide guidance on the management of patients with vascular liver diseases based on the best available evidence.

Summary

Extrahepatic abdominal surgery in patients with cirrhosis of the liver represents a growing clinical challenge due to the increasing prevalence of chronic liver disease and improved long-term survival of these patients. The presence of cirrhosis significantly increases the risk of perioperative morbidity and mortality following abdominal surgery. Advances in preoperative risk stratification, surgical techniques, and perioperative care have led to better outcomes, yet integration of these improvements into routine clinical practice is needed. These clinical practice guidelines provide comprehensive recommendations for the assessment and perioperative management of patients with cirrhosis undergoing extrahepatic abdominal surgery. An individualised patient-centred risk assessment by a multidisciplinary team including hepatologists, surgeons, anaesthesiologists, and other support teams is essential.
