Endoscopic papillectomy versus surgical ampullectomy for adenomas and early cancers of the papilla: a retrospective Pancreas2000/European Pancreatic Club analysis.

Objective: Ampullary neoplastic lesions can be resected by endoscopic papillectomy (EP) or transduodenal surgical ampullectomy (TSA) while pancreaticoduodenectomy is reserved for more advanced lesions. We present the largest retrospective comparative study analysing EP and TSA.

Design: Of all patients in the database, lesions with prior interventions, benign histology advanced malignancy (T2 and more), patients with hereditary syndromes and those undergoing pancreatoduodenectomy were excluded.

Long-Term Outcomes of Early Surgery vs Endoscopy First in Chronic Pancreatitis: Follow-Up Analysis of the ESCAPE Randomized Clinical Trial.

Importance: Patients with painful chronic pancreatitis and a dilated pancreatic duct can be treated by early surgery or an endoscopy-first approach.

Objective: To compare long-term clinical outcomes of early surgery vs an endoscopy-first approach using follow-up data from the ESCAPE randomized clinical trial.

Design, Setting, And Participants: Between April 2011 and September 2018, 88 patients with painful chronic pancreatitis were randomly assigned to early surgery or an endoscopy-first approach in 30 hospitals in the Netherlands collaborating in the Dutch Pancreatitis Study Group as part of the ESCAPE randomized clinical trial.

Mesenteric Artery Stenosis is a Risk Factor for Anastomotic Leakage in Colorectal Surgery.

Objective: Anastomotic leakage (AL) after colorectal surgery leads to substantial morbidity and mortality. Theoretically, compromised blood flow caused by mesenteric artery (MA) stenosis may create suboptimal healing conditions at the anastomotic site, increasing susceptibility to AL. The association between MA stenosis on pre-operative computed tomography (CT) scans and AL in patients undergoing colorectal surgery was investigated.

Fast-tracking ERCP learning with the Boškoski-Costamagna Trainer: results of a multicenter randomized clinical trial.

Background: Achieving competence in endoscopic retrograde cholangiopancreatography (ERCP) requires extensive training. Recognizing the potential of simulator-based education for safe and effective skill development, we aimed to assess whether initial training with the Boškoski-Costamagna ERCP Trainer (BCT) is beneficial compared with conventional training alone (i.e.

Large-scale multi-center CT and MRI segmentation of pancreas with deep learning.

Automated volumetric segmentation of the pancreas on cross-sectional imaging is needed for diagnosis and follow-up of pancreatic diseases. While CT-based pancreatic segmentation is more established, MRI-based segmentation methods are understudied, largely due to a lack of publicly available datasets, benchmarking research efforts, and domain-specific deep learning methods. In this retrospective study, we collected a large dataset (767 scans from 499 participants) of T1-weighted (T1 W) and T2-weighted (T2 W) abdominal MRI series from five centers between March 2004 and November 2022.

Pancreatic cancer surveillance: Risk stratification of individuals with a germline CDKN2A pathogenic variant.

Background: Individuals carrying a germline CDKN2A pathogenic variant (PV) are at a high risk of developing pancreatic ductal adenocarcinoma. Risk stratification could allow tailored surveillance.

Objective: To develop a Fine-Gray prediction model for the risk of PDAC in carriers of a CDKN2A PV.

Efficacy of EUS-guided keyhole biopsies in diagnosing subepithelial lesions of the upper gastrointestinal tract.

Tissue acquisition is required for diagnosis of subepithelial lesions (SELs). However, obtaining adequate tissue remains challenging. This study investigated an EUS-guided technique using a forceps to create a channel and take multiple biopsies from the center of the lesion, therefore called endoscopic ultrasound-guided keyhole biopsy (EUS-KB).

Twinning and homo-epitaxy cooperation in the already rich growth morphology of CaCO polymorphs. II. Calcite.

The two most abundant CaCO polymorphs, calcite and aragonite, are universally recognized for the richness of their morphology to which different twins make relevant contributions. The epitaxial transformation calcite ↔ aragonite has long been debated. While the twinning has been thoroughly treated, the homo-epitaxy occurring within each of these minerals has, inexplicably, been overlooked to date, both experimentally and theoretically.

Intravenous Lidocaine for Refractory Pain in Patients With Pancreatic Ductal Adenocarcinoma and Chronic Pancreatitis: A Multicenter Prospective Nonrandomized Pilot Study.

Introduction: Refractory pain is a major clinical problem in patients with pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP). New, effective therapies to reduce pain are urgently needed. Intravenous lidocaine is used in clinical practice in patients with PDAC and CP, but its efficacy has not been studied prospectively.

Endoscopic ultrasound with tissue acquisition of lymph nodes in patients with potentially resectable intrahepatic cholangiocarcinoma.

Lymph node (LN) involvement is a poor prognostic factor for patients with intrahepatic cholangiocarcinoma (iCCA). The aim of this study was to evaluate the yield and impact on clinical decision making of endoscopic ultrasound with tissue acquisition (EUS-TA) of LNs in patients with potentially resectable iCCA. In this multicenter cohort study, patients with potentially resectable iCCA and preoperative EUS between 2010 and 2020 were retrospectively included.

Contaminated duodenoscopes in ERCP: sensitivity of detection and risk of underdetection.

Background And Aims: Periodic duodenoscope cultures are essential to timely detect contamination, but their sensitivity remains unknown. This study aims to determine the sensitivity of duodenoscope cultures and to estimate the prevalence of contaminated duodenoscope use.

Methods: We combined duodenoscope microbiologic surveillance data from March 2015 to June 2022 with usage data to evaluate patient exposure to duodenoscopes contaminated with microorganisms of gut or oral origin (MGO).

Late cholangitis after pancreatoduodenectomy: A common complication with or without anatomical biliary obstruction.

Background: Postoperative cholangitis is a common complication after pancreatoduodenectomy that can occur with or without anatomical biliary obstruction. This study aimed to investigate the incidence, diagnosis, treatment, and risk factors of cholangitis after pancreatoduodenectomy.

Methods: We performed a retrospective cohort study of consecutive patients who underwent pancreatoduodenectomy in 2 Dutch tertiary pancreatic centers (2010-2019).

Risks of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis After Liver Transplantation.

Biliary complications are common after liver transplantation (LT). Endoscopic retrograde cholangiopancreatography (ERCP) is the preferred method to treat biliary complications. Nevertheless, ERCP is not without complications and may have a greater complication rate in the LT population.

Endoscopic resection in subepithelial lesions of the upper gastrointestinal tract: Experience at a tertiary referral hospital in The Netherlands.

Histological confirmation of subepithelial lesions (SELs) in the upper gastrointestinal tract remains challenging. Endoscopic resection of SELs is increasingly used for its excellent diagnostic yield and opportunity to do away with continued surveillance. In this study, we aimed to evaluate the indications, success rates and complications of different endoscopic resection techniques for SELs at a large, tertiary referral hospital in Rotterdam, The Netherlands.

Impact of long-term transmural plastic stents on recurrence after endoscopic treatment of walled-off pancreatic necrosis.

Background: Endoscopic transmural drainage (ETD) using double-pigtail stents (DPSs) is a well-established treatment for walled-off pancreatic necrosis (WON). This study aimed to compare outcomes in patients undergoing ETD with DPSs left indwelling versus those where stents were removed or migrated.

Methods: This retrospective multicenter cohort study included patients with WON who underwent ETD using DPSs between July 2001 and December 2019.

A critique of using epitaxial criterion to discriminate between protogenetic and syngenetic mineral inclusions in diamond.

Distinguishing syngenetic from protogenetic inclusions in natural diamonds is one of the most debated issues in diamond research. Were the minerals that now reside in inclusions in diamonds born before the diamond that hosts them (protogenesis)? Or did they grow simultaneously and by the same reaction (syngenesis)? Once previously published data on periclase [(Mg,Fe)O] and magnesiochromite (MgCrO) inclusions in diamond have been re-analysed, we show that the main arguments reported so far to support syngenesis between diamond and its mineral inclusions, definitely failed. Hence: (a) the epitaxial relationships between diamond and its mineral inclusion should no longer be used to support syngenesis, because only detecting an epitaxy does not tell us which was the nucleation substrate (there are evidences that in case of epitaxy, the inclusion acts as a nucleation substrate); (b) the morphology of the inclusion should no longer be used as well, as inclusions could be protogenetic regardless their shapes.

The role of endoscopic ultrasound in the detection of pancreatic lesions in high-risk individuals.

Individuals at high risk of developing pancreatic ductal adenocarcinoma are eligible for surveillance within research programs. These programs employ periodic imaging in the form of magnetic resonance imaging/magnetic resonance cholangiopancreatography or endoscopic ultrasound for the detection of early cancer or high-grade precursor lesions. This narrative review discusses the role of endoscopic ultrasound within these surveillance programs.
