Summary

Liver transplantation (LT) is an established life-saving procedure. The field of LT has changed in the past 10 years from several perspectives, with the expansion of indications, transplantation of patients with acute-on-chronic liver failure, evolution of transplant oncology, the use of donations after cardiac death, new surgical techniques, and prioritisation of recipients on the waiting list. In addition, the advent of organ perfusion machines, the recognition of new forms of rejection, and the attention paid to the transition from paediatric to adult patients, have all improved the management of LT recipients. The purpose of the EASL guidelines presented here is not to cover all aspects of LT but to focus on developments since the previous EASL guidelines published in 2016.

Main recommendations

MR1

ESGE recommends the following standards for Barrett esophagus (BE) surveillance:

• a minimum of 1-minute inspection time per cm of BE length during a surveillance endoscopy
• photodocumentation of landmarks, the BE segment including one picture per cm of BE length, and the esophagogastric junction in retroflexed position, and any visible lesions
• use of the Prague and (for visible lesions) Paris classification
• collection of biopsies from all visible abnormalities (if present), followed by random four-quadrant biopsies for every 2-cm BE length.

Strong recommendation, weak quality of evidence.

MR2

ESGE suggests varying surveillance intervals for dif ferent BE lengths. For BE with a maximum extent of ≥ 1 cm and < 3 cm, BE surveillance should be repeated every 5 years. For BE with a maximum extent of ≥ 3 cm and < 10 cm, the interval for endoscopic surveillance should be 3 years. Patients with BE with a maximum extent of ≥ 10 cm should be referred to a BE expert center for surveillance endoscopies.For patients with an irregular Z-line/columnar-lined esophagus of < 1 cm, no routine biopsies or endoscopic surveillance are advised.
Weak recommendation, low quality of evidence.

MR3

ESGE suggests that, if a patient has reached 75 years of age at the time of the last surveillance endoscopy and/or the patient’s life expectancy is less than 5 years, the discontinuation of further surveillance endoscopies can be considered.
Weak recommendation, very low quality of evidence.

MR4

ESGE recommends offering endoscopic eradication therapy using ablation to patients with BE and low grade dysplasia (LGD) on at least two separate endoscopies, both confirmed by a second experienced pathologist.
Strong recommendation, high level of evidence

MR5

ESGE recommends endoscopic ablation treatment for BE with confirmed high grade dysplasia (HGD) without visible lesions, to prevent progression to invasive cancer.
Strong recommendation, high level of evidence.

MR6

ESGE recommends offering complete eradication of all remaining Barrett epithelium by ablation after endoscopic resection of visible abnormalities containing any degree of dysplasia or esophageal adenocarcinoma (EAC).
Strong recommendation, moderate quality of evidence.

MR7

ESGE recommends endoscopic resection as curative treatment for T1a Barrett’s cancer with well/moderate differentiation and no signs of lymphovascular invasion.
Strong recommendation, high level of evidence.

MR8

ESGE suggests that low risk submucosal (T1b) EAC (i. e. submucosal invasion depth ≤ 500 μm AND no [lympho] vascular invasion AND no poor tumor differentiation) can be treated by endoscopic resection, provided that adequate follow-up with gastroscopy, endoscopic ultrasound (EUS), and computed tomography (CT)/positrion emission tomography-computed tomography (PET-CT) is performed in expert centers.
Weak recommendation, low quality of evidence.

MR9

ESGE suggests that submucosal (T1b) esophageal adenocarcinoma with deep submucosal invasion (tumor invasion > 500 μm into the submucosa), and/or (lympho)vascular invasion, and/or a poor tumor differentiation should be considered high risk. Complete staging and consideration of additional treatments (chemotherapy and/or radiotherapy and/or surgery) or strict endoscopic follow-up should be undertaken on an individual basis in a multidisciplinary discussion.
Strong recommendation, low quality of evidence

MR10a

ESGE recommends that the first endoscopic follow-up after successful endoscopic eradication therapy (EET) of BE is performed in an expert center.
Strong recommendation, very low quality of evidence.

MR10b

ESGE recommends careful inspection of the neosquamocolumnar junction and neo-squamous epithelium with high definition white-light endoscopy and virtual chromoendoscopy during post-EET surveillance, to detect recurrent dysplasia.
Strong recommendation, very low level of evidence.

MR10c

ESGE recommends against routine four-quadrant biopsies of neo-squamous epithelium after successful EET of BE.
Strong recommendation, low level of evidence

MR10d

ESGE suggests, after successful EET, obtaining fourquadrant random biopsies just distal to a normal-appearing neo-squamocolumnar junction to detect dysplasia in the absence of visible lesions.
Weak recommendation, low level of evidence.

MR10e

ESGE recommends targeted biopsies are obtained where there is a suspicion of recurrent BE in the tubular esophagus, or where there are visible lesions suspicious for dysplasia.
Strong recommendation, very low level of evidence.

MR11

After successful EET, ESGE recommends the following surveillance intervals:

• For patients with a baseline diagnosis of HGD or EAC: at 1, 2, 3, 4, 5, 7, and 10 years after last treatment, after which surveillance may be stopped.
• For patients with a baseline diagnosis of LGD: at 1, 3, and 5 years after last treatment, after which surveillance may be stopped.

Strong recommendation, low quality of evidence.

Introduction

Ulcerative colitis [UC] is a chronic inflammatory bowel disease [IBD] characterised by colonic inflammation extending to a variable extent from the rectum. Care of the patient with UC requires appropriate input from across the multiprofessional team. These guidelines summarise the recommended medical treatment for adults with UC. Other ECCO guidelines consider the approach to UC diagnosis and monitoring, nursing care, management of disease complications, risk of infection, and technical aspects of surgery. This document was prepared as part of a process that also led to the publication of a related guideline with recommendations on the surgical care of the patients with UC and on the medical aspects of the management of the patient hospitalised with severe UC. ECCO Guidelines on Therapeutics in Ulcerative Colitis: Surgical Treatment.
