National learning curve for laparoscopic hysterectomy and trends in hysterectomy in Finland 2000-2005.

BACKGROUND

Complications of laparoscopic hysterectomy (LH) have been evaluated with particular focus on quantities of urinary tract injuries. An earlier survey in the 1990s on LH in Finland indicated a decreasing trend in complications; our aim was to evaluate the current complications and hysterectomy trends.

METHODS

All hysterectomies in Finland performed for benign indication from 2000 to 2005 (n = 56 130) were included, data were obtained from the Finnish hospital care register. All major complications reported on LH were analysed; the data were collected retrospectively from the Patient Insurance Centre.

RESULTS

In 2000, the proportion of abdominal hysterectomy (AH) was 38%, vaginal hysterectomy (VH) 37% and LH 25%, whereas in 2005, the proportions were 26%, 45% and 29%, respectively. The overall incidence of major complications in LHs from 1992 to 1999 (LH n = 13 885) was 1.8% and from 2000 to 2005 (LH n = 13 942) it decreased to 1.0%. During the same time, urinary tract injuries decreased from 1.4% to 0.7%; in detail ureteral injuries decreased from 0.9% to 0.3%.

CONCLUSIONS

Laparoscopic and VHs have become more common in Finland than AH. Continuous instruction and training of the Finnish gynaecological surgeons has helped to diminish major complication rates and it seems that in LH, a plateau on the learning curve has been reached.
