Next-generation sequencing of pancreatic cyst wall specimens obtained using micro-forceps for improving diagnostic accuracy.

Pancreatic cysts are common incidental findings, with an estimated prevalence of 13% to 15% in imaging done for other reasons. Diagnosis often relies on collection of cyst fluid, but tissue sampling using micro-forceps may allow for a more reliable diagnosis and higher yield of DNA for next-generation sequencing (NGS). The primary aim was to assess the performance of NGS in identifying mucinous cyst.

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.

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.

Utility of palliative EUS-guided biliary drainage using lumen-apposing metal stents: a prospective multicenter feasibility study (with video).

Background And Aims: Biliary drainage with ERCP is successful in only 80% to 90% of cases of extrahepatic cholangiocarcinoma and pancreatic cancer. We present the results of a multicenter prospective study assessing the safety, feasibility, and quality of life of patients after EUS-guided biliary drainage (EUS-BD) with lumen-apposing metal stents after failed ERCP.

Methods: All consecutive adults with a dilated common bile duct (CBD) ≥14 mm secondary to inoperable malignant distal CBD stricture and failed ERCP biliary drainage were screened and recruited from 3 tertiary UK centers.

Comparison of the reverse bevel versus Franseen type endoscopic ultrasound needle.

Background: Reverse bevel (RB) needle is widely used for endoscopic ultrasound fine needle biopsy (EUS-FNB). A 3-plane symmetrical needle with Franseen geometry (FG) has recently become available.

Aim: To compare the clinical efficacy of FG to that of RB needle.

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.

Multicenter experience from the UK and Ireland of use of lumen-apposing metal stent for transluminal drainage of pancreatic fluid collections.

Background And Study Aims:  Pancreatic fluid collection (PFC) is a common complication of pancreatitis for which endoscopic ultrasound-guided drainage is first-line treatment. A new single-device, lumen-apposing, covered self-expanding metal stent (LAMS) has been licensed for PFC drainage. We therefore present our multicenter experience with the LAMS for PFC drainage in a multicenter prospective case series to assess success and complication rates.
