[The revised version of standard terminology in gastroenterological endoscopy - result of a consensus project of the german society for gastroenterology, digestive and metabolic diseases].

A uniform and comprehensive terminology is essential in the correct documentation of diagnostic or therapeutic endoscopic procedure. In the German-speaking world, the standard terminology available so far is based on a previous version published in 1999. Therefore, the German Society for Gastroenterology, Digestive and Metabolic Diseases (DGVS) has undergone a comprehensive revision and re-structuring of the terminology.

Endoscopic therapy for infected pancreatic necrosis using fully covered self-expandable metal stents: combination of transluminal necrosectomy, transluminal and percutaneous drainage.

Background/aims: Endoscopic transluminal therapy has become the standard of care as a less invasive alternative to surgery. In a retrospective case series of two tertiary referral centers we report on an individualized concept combining EUS-guided drainage with self-expanding metal stents, direct transluminal debridement und percutaneous drainage.

Methods: We treated 13 patients with infected pancreatic necrosis.

[Improvement of cost allocation in gastroenterology by introduction of a novel service catalogue covering the complete spectrum of endoscopic procedures].

Background: The German hospital reimbursement system (G-DRG) is incomplete for endoscopic interventions and fails to differentiate between complex and simple procedures. This is caused by outdated methods of personnel-cost allocation.

Methods: To establish an up-to-date service catalogue 50 hospitals made their anonymized expense-budget data available to the German-Society-of-Gastroenterology (DGVS).

[The role of peroral endoscopic myotomy (POEM) in achalasia].

Achalasia is a rare motility disorder of the oesophagus. Classic achalasia is characterised by a lack of propulsive peristalsis of the distal oesophagus and incomplete relaxation of the lower oesophageal sphincter (LES). Traditionally achalasia is treated either endoscopically by pneumatic balloon dilatation or laparoscopically by Heller's myotomy.

Propofol sedation for colonoscopy with a new ultrathin or a standard endoscope: a prospective randomized controlled study.

Background And Study Aims: The majority of colonoscopies in Germany are performed under conscious sedation. Previous studies reported that pediatric colonoscopes reduce the demand for sedative drugs and may improve cecal intubation. The aim of this study was to compare a new ultrathin and a standard colonoscope in terms of propofol demand during colonoscopy.

Simultaneous confocal laser endomicroscopy and chromoendoscopy with topical cresyl violet.

Background: Confocal laser endomicroscopy (CLE) has been shown to reliably predict histology during ongoing endoscopy. To unmask lesions for CLE, chromoendoscopy has been mandated. Usually fluorescein then serves as a contrast agent for CLE, but it does not allow direct nuclear visualization, must be injected, leads to a transient skin discoloration, and may have allergic side effects.

EUS-guided FNA of solid pancreatic masses: high yield of 2 passes with combined histologic-cytologic analysis.

Background: EUS-guided FNA (EUS-FNA) is an established tissue-acquisition technique, with most studies concentrating on cytologic analyses of specimens, with only few data existing on histologic assessment.

Objective: To assess the sensitivity of a combined analysis of histologic followed by cytologic tissue diagnosis.

Design: A retrospective 3-center study.

Attempted endoscopic en bloc resection of mucosal and submucosal tumors using insulated-tip knives: a pilot series.

Background And Study Aims: Endoscopic mucosal resection (EMR) of early gastrointestinal cancers has been shown to be effective in treating mucosal malignancies, but en bloc resection (where the entire tumor is removed in one piece) is often not achieved using conventional cap EMR. Other techniques, developed in Japan, include the application of different types of knife such as the insulated-tip instrument. We report our preliminary experience of the use of this knife, in conjunction with other techniques, in attempting en bloc resection of early mucosal cancers and adenomas and in the removal of submucosal tumors (SMTs) of the upper gastrointestinal tract.
