Journal ArticleDOI
The diagnostic work-up and outcomes of ‘presumed’ idiopathic acute pancreatitis: A post-hoc analysis of a multicentre observational cohort:
Nora D L Hallensleben,Devica S Umans,Stefan A.W. Bouwense,Robert C. Verdonk,Tessa E H Römkens,Ben J.M. Witteman,Matthijs P. Schwartz,Marcel Spanier,Robert J.F. Laheij,Hjalmar C. van Santvoort,Marc G. Besselink,Jeanin E. van Hooft,Marco J. Bruno +12 more
TL;DR: Assessment of the use of diagnostic modalities and their yield to establish an aetiology in ‘presumed’ IAP patients found Identification of an aETiology with subsequent treatment reduced the rate of recurrence.
Journal ArticleDOI
GWAS-uncovered SNPs in PLCE1 and RFT2 genes are not implicated in Dutch esophageal adenocarcinoma and squamous cell carcinoma etiology
Polat Dura,Caro V.V. Bregitha,Rene H. M. te Morsche,Hennie M.J. Roelofs,Jon O. Kristinsson,Theo Wobbes,Ben J.M. Witteman,Adriaan C.I.T.L. Tan,Joost P.H. Drenth,Wilbert H.M. Peters +9 more
TL;DR: It is unlikely that the PLCE1 rs2274223 and RFT2 13042395 SNPs play a role in EAC or ESCC susceptibility in Dutch Caucasians, in contrast to the modulation of the risk of ESCC in Asians.
Journal ArticleDOI

Boermeester,Hjalmar C. van Santvoort +28 more
TL;DR: Continuous and intermittent pain patterns in chronic pancreatitis do not seem to be the result of distinctly different pathophysiological entities, and the subjectively reported character of pain is not related to imaging findings or disease duration.
Journal ArticleDOI
Endoscopic versus surgical step-up approach for infected necrotizing pancreatitis (ExTENSION): long-term follow-up of a randomized trial.

TL;DR: At long-term follow-up, the endoscopic step-up approach was not superior to the surgical step- up approach in reducing death or major complications in patients with infected necrotizing pancreatitis.
Journal ArticleDOI
Multicenter study evaluating factors for stent patency in patients with malignant biliary strictures : development of a simple score model
Petra G. Van Boeckel,Ewout W. Steyerberg,Frank P. Vleggaar,M. J.M. Groenen,Ben J.M. Witteman,Bas L. Weusten,Han Geldof,Adriaan C.I.T.L. Tan,M.J.A.L. Grubben,Jan Nicolai,Peter D. Siersema +10 more
TL;DR: Besides plastic stents, stricture severity requiring preceding dilation, and initial higher bilirubin level were associated with a shorter period of stent patency, and a simple score model was able to predict stent occlusion and may aid in choosing the most appropriate stent type in individual patients.
