The authors concern five years long retrospective analysis of miniinvasive endoscopical and surgical methods from point of view the occurence of perforation complications. The frequency is compared with dates in basic literature sources. They analyse the mortality , morbidity and therapy in perforation incidents. Results are full comparable with the literature dates, in the region of upper gastrointestinal tract and biliary ducts are the results better. The main risk factors for complications (incl. perforations) of miniinvasive procedures are the overestimation of own possibilities, underestimation of findings and surgery, late sending to surgery and total status of the patient. To the succesfull solution of complication the multidisciplinary approache is needed.
