Biopsy surveillance is still necessary in patients with Barrett's oesophagus despite new endoscopic imaging techniques.
Klaus Egger,Martin Werner,Alexander Meining,R. Ott,Hans-Dieter Allescher,H. Hofler,Meinhard Classen,Thomas Rösch +7 more
TL;DR: Careful endoscopic observation and stepwise four quadrant biopsy still represent the gold standard for surveillance of Barrett’s oesophagus and AF and MB are not suitable techniques for reducing the high numbers of routine biopsies needed for finding additional foci of HGD or cancer.

The Munich Barrett follow up study: suspicion of Barrett's oesophagus based on either endoscopy or histology only--what is the clinical significance?
A Meining,R. Ott,Ingrid Becker,S Hahn,J Mühlen,Martin Werner,H. Hofler,Meinhard Classen,Walter Heldwein,Thomas Rösch +9 more
TL;DR: Even in a specialised gastroenterology setting, reproducibility of presumptive endoscopic or histological diagnoses of Barrett’s oesophagus at follow up were poor and hence meticulous follow up may not be required.

Initial experience with a new, partially covered Wallstent for malignant biliary obstruction.
TL;DR: Covering biliary metal stents is a potential solution to prevent tissue ingrowth, however, current prototypes need to be improved in order to achieve this goal.

Long-term outcome in patients with advanced hilar bile duct tumors undergoing palliative endoscopic or percutaneous drainage.
P. Born,T. Rösch,Brühl K,W. Sandschin,N. Weigert,R. Ott,Eckart Frimberger,Hans-Dieter Allescher,W. Hoffmann,Horst Neuhaus,Meinhard Classen +10 more
TL;DR: Palliative treatment in patients with advanced Klatskin tumors is still suboptimal, even when combined endoscopic and percutaneous techniques are used in the same institution, allowing treatment to be tailored to the individual patient's needs.

Bacteriobilia in percutaneous transhepatic biliary drainage: occurrence over time and clinical sequelae. A prospective observational study.
T Rösch,A. Triptrap,P. Born,R. Ott,N. Weigert,Eckart Frimberger,Hans-Dieter Allescher,Meinhard Classen,K. Kamereck +8 more
TL;DR: Bacteriobilia is initially a frequent, and later a regular, event in PTBD; however, clinically significant complications are rare during the long‐term course and limited to the initial, more invasive, phase of PTBD.
