The summer of this year is here - at least on our half of the globe. During the summer - in June, July and August - the Quiz will be quite easy for two reasons. First, a quick answers save You time to be out in the sun. Second, You do not have to be an expert in endoscopy to manage in this quiz during the summer. So - if You are a health care professional just thinking of starting a career in endoscopy, please have a try - You might find it interesting!

In 1994 a new scientifically validatet classification of reflux oesophagitis was presented at the World Congress of Gastroenterology, hence the name LA Classification. According to this endoscopic grading system the severity of the oesophagitis is divided into four grades, Grade A, Grade B, Grade C and Grade D. Since 1994 this classification has been videly accepted and used by endoscopists over the world.

The images above represents a typical grade ? reflux oesophatis - well, what grade?

Answer

Reflux oesophagitis grade D according to the LA-classification.

The Los Angeles Classification System for the endoscopic assessment of reflux oesophagitis:
GRADE A: One or more mucosal breaks no longer than 5 mm, non of which extends between the tops of the mucosal folds
GRADE B: One or more mucosal breaks more than 5 mm long, none of which extends between the tops of two mucosal folds
GRADE C: Mucosal breaks that extend between the tops of two or more mucosal folds, but which involve less than 75% of the oesophageal circumference
GRADE D: Mucosal breaks which involve at least 75% of the oesophageal circumference

The majority of this months answers was grade D. However, about 25% answered grade C, and they might not be wrong, but we think this is grade D. These classifications are not always quite easy!
