title: [Rates of complications after laparoscopic cholecystectomy depending on the coagulation technique--a comparative study].
abstract: BACKGROUND
  This study analyzes the impact of coagulation instrument devices used during gallbladder removal. Standard electrocautery is compared to the use of harmonic scapel. To determine whether the different principles of these instruments are the key to the frequency and severity of complications during laparoscopy.
  
  
  METHODS
  Data collected from a statistically significant number of patients were evaluated and the experiment on porcine liver tissue was conducted to illustrate histopathological changes in tissues after the use of electrocautery and harmonic scalpel.
  
  
  CONCLUSIONS
  The presented data and the results of the experiment on animal liver tissue show that the use of harmonic scalpel during gallbladder removal is a safer technique with much lower risk of complications than the use of ordinary electrocautery.
