A case of idiopathic chylous ascites.

Chylous ascites is a rare condition found in 1 in 20 000 patients admitted to hospital with abdominal distention. It is caused by a limited number of pathologies but can, in rare situations, be idiopathic. Its management is difficult and usually involves correcting the primary pathology, making idiopathic chylous ascites particularly difficult to manage. We present a case of idiopathic chylous ascites extensively investigated over a period of several years. An incidental finding of B cell lymphoma was initially suspected to have been the primary cause of the ascites; however, after successful treatment of this condition, the patient's ascites did not resolve. Diagnostic difficulties and management are discussed and an overview of the diagnostic process is outlined through this case.

EUS-guided choledochoduodenostomy with electrocautery-enhanced lumen-apposing metal stents in patients with malignant distal biliary obstruction: multicenter collaboration from the United Kingdom and Ireland.

BACKGROUND AND AIMS: EUS-guided choledochoduodenostomy (EUS-CDD) with an electrocautery-enhanced lumen-apposing metal stent (EC-LAMS) has emerged as a viable method of establishing biliary drainage in patients with malignant distal biliary obstruction (MDBO). Our aim was to assess the efficacy, safety, and outcomes in patients with MDBO who underwent EUS-CDD with an EC-LAMS. METHODS: A retrospective review of consecutive patients with MDBO who underwent EUS-CDD with EC-LAMSs at 8 tertiary institutions across the United Kingdom and Ireland between September 2016 and November 2020 was undertaken. RESULTS: One hundred twenty patients (55% men) with a median age of 73 years (interquartile range, 17; range, 43-94) were included. The median follow-up period in 117 patients was 70 days (interquartile range, 169; range, 3-869), and 23 patients (19.2%) were alive at the end of the follow-up. Three patients were lost to follow-up. Technical success was achieved in 109 patients (90.8%). Clinical success (reduction of serum bilirubin to ≤50% of original value within 14 days) was achieved in 94.8% of patients (92/97). The adverse event rate was 17.5% (n = 21). Biliary reintervention after initial technical success was required in 9 patients (8.3%). CONCLUSIONS: EUS-CDD with EC-LAMSs at tertiary institutions within a regional hepatopancreatobiliary network for treatment of MDBO was effective in those where ERCP was not possible or was unsuccessful. When technical failures or adverse events occur, most patients can be managed with conservative or endoscopic therapy.

Long-term outcomes of liver transplant recipients followed up in non-transplant centres: Care closer to home.

INTRODUCTION: Increasing rates of liver transplantation and improved outcomes have led to greater numbers of transplant recipients followed up in non-transplant centres. Our aim was to document long-term clinical outcomes of liver transplant recipients managed in this 'hub-and-spoke' healthcare model. METHODS: A retrospective analysis of all adult patients who underwent liver transplantation between 1987 and 2016, with post-transplant follow-up in two non-transplant centres in the UK (Nottingham) and Canada (Ottawa), was performed. RESULTS: The 1-, 5-, 10- and 20-year patient survival rates were 98%, 95%, 87% and 62%, and 100%, 96%, 88% and 62% in the Nottingham and Ottawa groups, respectively (p=0.87). There were no significant differences between the two centres in 1-, 5-, 10- and 20-year cumulative incidence of death-censored graft-survival (p=0.10), end-stage renal disease (p=0.29) or de novo cancer (p=0.22). Nottingham had a lower incidence of major cardiovascular events (p=0.008). CONCLUSION: Adopting a new model of healthcare provides a means of delivering post-transplant patient care close to home without compromising patient survival and long-term clinical outcomes.

The Impact of Preexisting and Post-transplant Diabetes Mellitus on Outcomes Following Liver Transplantation.

BACKGROUND: Diabetes mellitus (DM) is said to adversely affect transplant outcomes. The aim of this study was to investigate the impact of pre-existing and new-onset DM on liver transplantation (LT) recipients. METHODS: A single-center retrospective analysis of prospectively collected data of LT recipients (1990-2015) was undertaken. RESULTS: Of the 2209 patients, 13% (n = 298) had Pre-DM, 16% (n = 362) developed post-transplant diabetes mellitus (PTDM), 5% (n = 118) developed transient hyperglycemia (t-HG) post-LT, and 65% (n = 1431) never developed DM (no DM). Baseline clinical characteristics of patients with PTDM were similar to that of patients with Pre-DM. Incidence of PTDM peaked during the first year (87%) and plateaued thereafter. On multivariate analysis (Bonferroni-corrected), nonalcoholic fatty liver disease and the use of tacrolimus and sirolimus were independently associated with PTDM development. Both Pre-DM and PTDM patients had satisfactory and comparable glycemic control throughout the follow-up period. Those who developed t-HG seem to have a unique characteristic compared with others. Overall, 9%, 5%, and 8% of patients developed end-stage renal disease (ESRD), major cardiovascular event (mCVE), and de novo cancer, respectively. Both Pre-DM and PTDM did not adversely affect patient survival, retransplantation, or de novo cancer. The risks of ESRD and mCVE were significantly higher in patients with Pre-DM followed by PTDM and no DM. CONCLUSIONS: In this largest nonregistry study, patients with Pre-DM and PTDM share similar baseline clinical characteristics. Pre-DM increases the risk of ESRD and mCVE; however, patient survival was comparable to those with PTDM and without diabetes. Understanding the impact of PTDM would need prolonged follow-up.
