Laparoscopy in the last decade of the millennium: have we really improved?
BACKGROUND
The aims of the study were to evaluate the evolution of laparoscopic surgery during the past decade in terms of variations in the quality (complexity) of the procedures performed and of modifications in patient outcome.


METHODS
A retrospective analysis was performed of 3022 consecutive patients undergoing 99 different laparoscopic procedures at a center specialized in laparoscopic abdominal surgery. All the procedures were classified according to three classes of complexity. Results relating to the first 1511 patients were compared to those of the last 1511 patients.


RESULTS
In the second group, medium- to high-class complexity procedures significantly increased, conversion rate was higher only for straightforward procedures, duration of low- to medium-class complexity procedures decreased, only the rate of slight complications increased, and mean postoperative hospital stay was longer. Frequency of conversion in medium- to high-class complexity procedures and severe complications was not different in the two periods.


CONCLUSIONS
The quality of laparoscopic surgery has improved during the past decade, with no increase in the frequency of conversion or of major complications.
