Minimal standard terminology for digestive endoscopy: results of prospective testing and validation in the GASTER project.
BACKGROUND AND STUDY AIMS: Standardization of the endoscopic report is a key issue for future research in the field of digestive endoscopy. The Minimal Standard Terminology (MST) has been proposed by the European Society for Gastrointestinal Endoscopy (ESGE) as a structured language for production of computerized endoscopic reports. The aim of this study was to validate version 1.0 of this terminology prospectively, by collecting cases in a multicenter, multilingual trial. METHODS: Endoscopic cases (esophagogastroduodenoscopy [EGD], colonoscopy, endoscopic retrograde cholangiopancreatography [ERCP]) were prospectively collected in nine university hospitals in Europe, using the same software. Reports were produced in the local language, but the software allowed comparison of reports between languages, and global analysis of the database. Outcome measures were the adequacy of terms proposed in the MST to describe "reasons for performing an endoscopy", "findings", and "endoscopic diagnoses", frequency of use and content of free-text fields, and types of lesions described. RESULTS: A total of 6,232 reports were analyzed, including 3,447 gastroscopies, 1,743 colonoscopies, and 1,042 ERCPs. Overall, terms originally contained in the MST were adequate to describe fully 91.0% of all examinations where "reasons for endoscopy" were described, 99.5 % of examinations where "findings" were described, 95.8% of all examinations containing descriptions of "endoscopic diagnosis", 98.9% of examinations containing descriptions of "additional diagnostic procedures", and 94.8 % of examinations containing descriptions of "additional therapeutic procedures". Free-text fields were only used in the other cases (less than 5% of cases in average). CONCLUSIONS: The MST appeared adequate to cover a large part of routine endoscopy reports, and could thus be used as a tool for standardization of endoscopic reports in clinical practice. The latter could be significantly improved by the use of a structured and standardized terminology for the production of endoscopic reports.

The GASTER project: building a computer network in digestive endoscopy: the experience of the European Society for Gastrointestinal Endoscopy. Gastrointestinal Endoscopy Application for Standards in Telecommunication, Education and Research.
Digestive endoscopy is currently the main diagnostic procedure for investigation of the digestive tract whenever a digestive disease is suspected. From 1970 to 1985, digestive endoscopy was performed with endoscopes equipped with fiberoptic bundles, whereas the last decade was marked by the development of electronic endoscopes, characterized by the presence of a CCD (charge coupled device) at the tip of the endoscope. Thus the physician looks at a TV screen to control the procedure and examine in detail the gut wall. Endoscopes examine the foregut until the duodenum and the hindgut, up to the three last intestinal loops. When the endoscopic workstation comprises a computer, it is possible to acquire electronic images during the endoscopy and use these images as support of the information about the results of the procedure. These numeric images can then be stored in databases containing text attached to them. Starting with these images, one may expect many developments in the near future that will change the management of the patient with digestive diseases. Physicians will become able to exchange images and text related to one patient or one procedure, although they are equipped with different workstations. Therefore, it is obvious that the information exchanged must be written in a standard format that makes it understandable by all systems. The European Society of Gastrointestinal Endoscopy is a scientific society that groups most of the gastroenterologists in Europe. This society has initiated a research program to develop standards for the exchange of images and text. The Gastrointestinal Endoscopy Applications for Standards in Telecommunication, Education, and Research (GASTER) project intends to implement a multimedia database of endoscopic images based on a standard format of images and a standard terminology for descriptive terms. These standards must be validated by use in different endoscopy units. The database will collect images from these centers that will be linked to the coordinating center through a network based on an integrated services digital network (fast electronic connection). This database will then be used for the development of computer applications. The output of the GASTER project will bring advances at three levels: (1) The physicians will be able to exchange images about the procedures their patients have undergone and will thus obtain more complete information, improving quality of care. They will also benefit from help-to-decision applications based on validated reference images from the database. (2) At the patient level, the quality of care will be improved through a better dissemination of information between the physicians in charge of the patient, thus there is better follow-up of the patient and a decrease in redundant examinations. (3) At the level of national health care systems, the benefit will be a decrease in cost of care due to a better follow-up of the patients, a decrease in redundant examinations, and a faster decision made to treat the patient. The possibility of consulting a database of a scientifically validated images used as reference material will also improve quality control in digestive endoscopy.

The minimal standard terminology for digestive endoscopy: introduction to structured reporting.
The wider use of computers for the management of endoscopic data and the use of electronic endoscopes for the production of high quality endoscopic images has made the standardization of terminology and images formats necessary in digestive endoscopy reports. The European Society for Gastrointestinal Endoscopy and the American Society for Gastrointestinal Endoscopy have combined their efforts to propose a Minimal Standard Terminology for Computerized Databases in Endoscopy. This terminology is based on the following principles: no term describing findings less frequent than 1%, of the daily practice, and no term based on subjective impressions. The Minimal Standard Terminology has been developed according to the natural process of constructing an endoscopic report in natural language and deals with the following: reasons for performing the examination, endoscopic findings, endoscopic diagnosis, additional therapeutic and diagnosis procedures (biopsies, etc.). It is subdivided according to the main organs examined with an endoscopy. Until now, the Minimal Standard Terminology was tested in many centers and was shown to accurately cover 95% of routine examinations for the upper gastrointestinal tract, colonoscopy and cholangio-pancreatography. It is currently being tested in an a prospective way in several centers in Europe (with a grant from the European Commission DGXIII-C4) and in the USA (with grant from the AHDHF).

The role of therapeutic endoscopy associated with extracorporeal shock-wave lithotripsy and bile acid treatment in the management of Caroli's disease.
BACKGROUND AND STUDY AIMS: Caroli's disease causes relapsing episodes of cholangitis due to the presence of intrahepatic lithiasis. Strategies for cholangitis prevention are still widely debated. Ursodeoxycholic acid, hepaticojejunostomy, partial hepatectomy, or transplantation, have all been proposed as therapeutic options. The aim of this study was to evaluate the role of therapeutic endoscopy, and especially endoscopic sphincterotomy (ES), in the management of Caroli's disease. PATIENTS AND METHODS: Between 1983 and 1995, six patients with Caroli's disease (mean age 52, range 17-75) underwent endoscopic retrograde cholangiopancreatography (ERCP) for acute cholangitis. Sphincterotomy was performed if common bile duct stones were present. Extracorporeal shock-wave lithotripsy, (ESWL) or intraductal electrohydraulic lithotripsy (IEL) were performed if necessary. RESULTS: The mean number of endoscopic sessions per patient was four (range three to seven). Sphincterotomy was performed in five patients and cholangioscopy in three. ESWL was performed twice in each of four patients. A Strecker expandable metal stent was placed in one patient to maintain sphincterotomy patency. In one patient, two sessions of IEL and pulsed laser were carried out. Complete clearance of intrahepatic stones was achieved in four of the six subjects (66.6%) and partial clearance in two patients. No morbidity or mortality was observed. During the follow-up (mean 6.2 years; range: 2.1-16.3), only two patients had acute cholangitis at nine months and three years, respectively, after the endoscopic treatment. Both had residual intrahepatic stones left after the initial endoscopic attempt at clearance. CONCLUSION: ERCP is a necessary diagnostic procedure which should always be carried out in patients with Caroli's disease. Our experience shows that ES does not result in an increased incidence of cholangitis and that therapeutic endoscopy allows complete clearance of intrahepatic stones in the majority of patients with unresectable symptomatic Caroli's disease. Nevertheless, the oncological risk in these patients remains unchanged, and they still have an increased risk of cholangiocarcinoma.

Lymphangioma of the oesophagus. Diagnosis and treatment by endoscopic polypectomy.
Finding a lymphangioma in the upper digestive tract is a rather infrequent event. A case of a 64-year-old man is reported. Diagnosis was made in the course of an endoscopic oesophagogastroduodenal examination and tumor excision with a diathermy snare at the same time. Two years after resection there was no sign of recidivation of the tumor.
