BACKGROUND:The technique of laparoscopic cholecystectomy(LC) has not changed over the past recent years; therefore thepossibility is open to study its learning curve.

METHODS:Retrospectively, every third year's LCs were analysed between 1994 and 2012. The learning curves of surgeons andnovices were defined in the department. The surgeons havescored the laparoscopic technique of their colleagues on ascale of 1 to 10 and operation time (OT) was examined in lightof the assistant's technique.

RESULTS:2,216 LCs were performed in the examined period.The average OT of the department was 78.3 minutes in 1994,which had decreased to 45.4 minutes (42.0%) by 2003. The improvement rates of surgeons and novices were 36.7% andrespectively 9.9%, and the variance between the minimumand maximum OT changed in parallel. The OT in the initial 3 years of learning had become 13% shorter by 2006 and thefirst section of the learning curve has also become steeper. Incase of surgeons whose technical points were low and OT wasshort, the assistants average technical score was significantly higher than in case of surgeons whose technical score was highand the OT was short.

CONCLUSION:The OT alone is not an objective factor in the definition of the surgical technique.
