Journal ArticleDOI
Endoscopic Mucosal Resection Outcomes and Prediction of Submucosal Cancer From Advanced Colonic Mucosal Neoplasia
Alan C. Moss,Michael J. Bourke,Stephen J. Williams,Luke F. Hourigan,Gregor J. Brown,William Tam,Rajvinder Singh,Simon A. Zanati,Robert Chen,Karen Byth +9 more
TL;DR: In this paper, an intention-to-treat, multicenter study of endoscopic mucosal resection (EMR) was conducted in the Australian Colonic Endoscopic (ACE) resection study group.
Journal ArticleDOI
Long-term adenoma recurrence following wide-field endoscopic mucosal resection (WF-EMR) for advanced colonic mucosal neoplasia is infrequent: results and risk factors in 1000 cases from the Australian Colonic EMR (ACE) study
Alan C. Moss,Stephen J. Williams,Luke F. Hourigan,Gregor J. Brown,William Tam,Rajvinder Singh,Simon A. Zanati,Nicholas G. Burgess,Rebecca Sonson,Karen Byth,Michael J. Bourke,Michael J. Bourke +11 more
TL;DR: Following colonic WF-EMR, early recurrent/residual adenoma occurs in 16%, and is usually unifocal and diminutive, as with strict colonoscopic surveillance, it can be managed endoscopically with high success rates.
Journal ArticleDOI
Risk Factors for Intraprocedural and Clinically Significant Delayed Bleeding After Wide-field Endoscopic Mucosal Resection of Large Colonic Lesions
Nicholas G. Burgess,Andrew J. Metz,Stephen J. Williams,Rajvinder Singh,William Tam,Luke F. Hourigan,Luke F. Hourigan,Simon A. Zanati,Gregor J. Brown,Gregor J. Brown,Rebecca Sonson,Michael J. Bourke +11 more
TL;DR: In a prospective study of patients undergoing WF-EMR of large sessile colonic polyps, IPB is associated with larger lesions, lesion histology, and Paris endoscopic classification of type 0-IIa + Is, and is a marker for recurrence.
Journal ArticleDOI
A prospective randomized trial of cannulation technique in ERCP: effects on technical success and post-ERCP pancreatitis.
Adam A. Bailey,Michael J. Bourke,Stephen J. Williams,P. R. Walsh,M. A. Murray,Eric Y. Lee,Vu Kwan,P. M. Lynch +7 more
TL;DR: The guide-wire technique improves the primary success rate for biliary cannulation during ERCP but does not reduce the incidence of PEP compared to the conventional contrast technique.
Journal ArticleDOI
Large refractory colonic polyps: is it time to change our practice? A prospective study of the clinical and economic impact of a tertiary referral colonic mucosal resection and polypectomy service (with videos).
TL;DR: Coloscopic polypectomy performed by a TRCPS on large or difficult polyps is technically effective and safe and results in major cost savings and avoids the potential complications of colonic surgery.
