Jessica M. Leers,C. Vivaldi,H. Schäfer,Marc Bludau,Jan Brabender,Georg Lurje,Till Herbold,Arnulf H. Hölscher,Ralf Metzger +8 more
TL;DR: Implantation of covered SEMS in patients with esophageal leak or perforation is a safe and feasible alternative to operative treatment and can lower the interventional morbidity rate.
Journal ArticleDOI
The Molecular Signature of Normal Squamous Esophageal Epithelium Identifies the Presence of a Field Effect and Can Discriminate between Patients with Barrett's Esophagus and Patients with Barrett's-Associated Adenocarcinoma
Jan Brabender,Paul Marjoram,Reginald V. Lord,Ralf Metzger,Dennis Salonga,Daniel Vallböhmer,H. Schäfer,Kathleen D. Danenberg,Peter V. Danenberg,Florin M. Selaru,Stefan E. Baldus,Arnulf H. Hölscher,Stephen J. Meltzer,Paul M. Schneider +13 more
TL;DR: The first comprehensive investigation of a carcinogenic field effect in Barrett's esophagus disease is provided, and patients could be correctly characterized according to their pathologic classification by applying a linear discriminant analysis.
Journal ArticleDOI
Botox, dilation, or myotomy? Clinical outcome of interventional and surgical therapies for achalasia
Christian A. Gutschow,Ulrich Töx,Jessica M. Leers,H. Schäfer,Klaus L. Prenzel,Arnulf H. Hölscher +5 more
TL;DR: Surgical myotomy is the most reliable first-line therapy for achalasia, particularly in patients with a high sphincter pressure and moderate esophageal dilatation, and should be reserved for exceptional cases.
Journal ArticleDOI
Giant adenomas of the rectum: complete resection by transanal endoscopic microsurgery (TEM).
TL;DR: TEM is an alternative method for the resection of large benign rectal tumors located in the mid- and upper third of the rectum and the main postoperative complication is suture-line insufficiency, which generally heals by conservative treatment.
Journal ArticleDOI
Gastric Outlet Obstruction After Esophagectomy: Retrospective Analysis of the Effectiveness and Safety of Postoperative Endoscopic Pyloric Dilatation
Martin K. H. Maus,Jessica M. Leers,Till Herbold,Marc Bludau,Seung-Hun Chon,Robert Kleinert,Daniel A. Hescheler,Elfriede Bollschweiler,Arnulf H. Hölscher,H. Schäfer,Hakan Alakus +10 more
TL;DR: Endoscopic pyloric dilatation after esophagectomy is a safe procedure for treatment of gastric outlet obstruction and the use of 20-mm balloons has been abandoned in the clinic.
