[Juxtapapillary diverticulum--the effect on endoscopic interventions and diagnosis].

Juxtapapillary diverticula are found in the contemporary population according to various sources in 10-20%. Their importance in the pathogenesis of some diseases and symptoms is beyond doubt, while in other cases, such as pancreatic diseases, it is doubtful. In the submitted material the authors evaluate experience assembled during endoscopic examinations and interventions on the papilla Vateri implemented in 1988. The authors confirm the more frequent prevalence of choledocholithiasis in patients with juxtapapillary diverticula. Juxtapapillary diverticula make endoscopic examination as well as possible subsequent interventions more difficult. It is necessary to use more complicated procedures, specially those with guides. Diverticula may even be the cause of failure or complications such as haemorrhage or perforation. For the experienced endoscopist there are, however, no decisive impediment.
